Clean Installation Ubuntu 14.04.3 LTS on Toshiba Portege Z930

First of all, not I being despise of using Windows, but I missed working on Linux environment computer. The office Toshiba Portege Z930 Ultrabook has been handed over to me recent month a go, comes with pre-installed Windows 8 Single Language, then I tried to upgraded to Windows 8.1 Single Language. After few days using Windows 8.1 as working environment to develop web apps, writing reports, do work administration, doing some research or technical paper, or simply do technical writing.

Then, it snaps me hard one day. I missed working on Linux, those Ubuntu, Linux Mint, Lubuntu, or Kali Linux. But, I can't do anything to converted these Windows 8.1 to any Linux. Main reason that, these are office laptop, and when it handed to me Libre Office still can't maintain Microsoft Office 2010 docx format. Windows 10 came out, I'm eager to tried it, after upgrade it and a whole month trying, still deep down I still missed working with Linux.

One day, I discretely installed Ubuntu 14.04.3 LTS on these machine, but disaster happen. The impatience made me blind and fool, these device had UEFI BIOS Boot mode and come with Secure Boot, instead of Legacy Boot mode. After, first time clean installation, the boot loader are not detected. Even worst, the Operating System isn't detected at all by BIOS. Again I said to myself, this is a disaster! I tried everything I could to find resource and knowledge from any Ubuntu users forum, stackexchange, or any blog posts that come out from search engine, but after three days trying to repair boot loader, any EFI or GRUB, still failed.

For the record, yes I already tried with Boot Repair GUI which install to Live USB mode, with these step:

Code:
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair
sudo boot-repair &


try with recommended solution and come out with these result http://paste.ubuntu.com/13310433/, or advanced mode and choose nomodeset, reinstalled grub and rewrite the efi and having these result http://paste.ubuntu.com/13322056/. Still nothing happen, trying with manage flags on GParted, failed result also.

On the verge of giving up, I found a blog post that gave me something useful. Thanks to J.A. Watson post on ZDNet explaining how he install clean Linux or rather Ubuntu distros and derived on his laptop. Let go the chance on using UEFI and Secure Boot mode and revert back to CSM and not Secure Boot mode, and whala... Ubuntu running on my office Ultrabook.

But, that UEFI Boot problem still bothering me, why boot-repair couldn't repair it, and why Ubuntu still couldn't be able installed on Toshiba Portege Z930 with UEFI and Secure boot, or that just happen with these Ultrabook that handed to me?

If you readers have same problem and had solution, I'm open to hear or read it. Thank you.

Hidden Game in Your Smartphone

Game for get rid of your boredom, while waiting or on journey. But games nowadays, especially mobile games are an online based games, rare we could find an offline one. Although, many we could try to look for in Apple Apps Store for Apple based smartphone or tablet, Google Play Store for Android base, or other mobile apps store platform. Still, that’s with condition you already download and installed the games first.

How about you forgot to installed some offline games, while you not able to find any data connection, not even a Wi-Fi, and you need some games for killing boredom or time.

Don’t you worry, your smartphone have a solution to that situation. Do you have Chrome Mobile Browser installed yet? For those Android based smartphone or tablet, I'm sure you already are, but checked you have the newest version. For another mobile platform, make sure you already have one.

Why do you need a browser, but no data connection available? How am I supposed to browse Internet to looking a game for first place? I’m sure you all have the same question and think that I’m a retard giving this suggestion. Wait for thought of that, just follow my lead first, complaints later.

Already open the Chrome browser? Alright, when you’ve already open then you will find picture of T-Rex on gray pixelate. Some say that is the symbol of pre-historic or pre-internet era, perhaps. But wait, push that T-Rex and she’s moving on the track! That’s the game, that I wanted to inform you earlier.


If that is not enough or still got bored, I still have one more solution. But, this applied only for Android Lollipop based mobile platform. You just navigate to Setting page, by click Setting button on home launcher or in all apps or by sweep on status bar from top to bottom. On setting page, click on About Phone and click several times until pop a circle in the center of the page.

Now, click and then press little circle until become a lollipop candy as Android Lollipop logo. Press and hold little more and you will get some animated scrolling page, click it anywhere on screen. You will get a Flappy Green Droid game!


Hidden on plain sights right? That’s Google.

PDF Reader and Editor on Android

Want to not just read of your PDF file on your Android devices? perhaps I was too late to found out, Xodo and PDF Max Free could be some examples of freemium apps that could edit your files or PDF Tools, a premium apps with features that we all needed to edit a PDF files.

Picture 1. Some PDF Editor Available on Google Play Store

Well, which one of these apps that wins my heart of read, edit, annotate, or sign a PDF document. I've been tried on all of these apps for quite some time, using it, test it and (perhaps) buying it. As we noted, PDF Tools is a premium apps, but in here we use freeware tools or lite version first. 

Xodo 

The first freemium apps that I encountered and been using it is Xodo. As a freeware apps, Xodo offering a great features, almost as great as premium one. Let's we break down these features. 

In Xodo every buttons is place on top of apps, button to arranges page view, search text, share button, page view button, bookmarks button, editable features button and other menu button represent by three little box arrange vertically. Well, that's the basic and all of the buttons available in the apps.
Picture 2. Default Button in Xodo
In edit function, we'll be seen several buttons more. Comment with the text style buttons, strikethrough and underline style, signature, freehand, eraser, textbox, several shape buttons. The eraser itself only erase the freehand draw, and signature is literally we do signature on paper in these apps.

Picture 3. Edit Function Inside Edit Button in Xodo Apps, Up: when screen tilt landscape mode, Down: default potrait mode

We could add text by using textbox function and place it wherever we like to position to. We also can modify text style, the text color, font size, font type, etc. After textbox added, we could changes its styles by tap the textbox and pop up 3 buttons on top of it, also able to changes text or delete. How about sign a document? No problem, there is Sign feature in Xodo. Just hit the sign button and you just sign your document, whether using your finger to create hand signature or using smartphone stylus.
Picture 4. Xodo Hand Signature Feature
That's the things of beauty in Xodo, everything is smoothly to edit without any problems with, but we couldn't delete, extract, or insert page(s), only rotate page. Insert and extract images also unavailable in Xodo, we could draw shape or something but not place an images. The only file type that could be handled by Xodo is PDF format.

PDF Max Free

While we can't do much on pages with Xodo, in PDF Max Free we could add, extract, delete, and rotating pages. 
Picture 5. Page Editing in PDF Max Free Apps

The editing buttons is a small area place on right side of screen, but don't you worry, it hold hidden buttons when you scroll up.
Picture 6. PDF Max Free Button (break down as screen is not big enough)
There's annotation, highlight, strikethrough, underline, squilly, draw shapes, freehand tool, signing tool, stamp, and many more. Yes, more editing tools than Xodo. Little note that I feels when add textbox or posisitioning it, is not as smooth as I used Xodo. Not just positioning, resizing also made me some issues. 

The common thing with Xodo is unable to insert images in to pdf document. This is the downside with freemium apps, I hope this problem could be fixed with premium one.

PDF Tools (lite)

Well, the last tools I itch to used is PDF Tools Premium. But, unfortunately I am still afraid to bought it. I tried the lite version first, but I think it's not represent the real capabilities from the apps.

Why? Too many essential features are locked, so I wouldn't know if these apps is powerful as they said. From the features that been preview on apps, is capable to split or merge pdf, delete pages, flip or rotate pages, create pdf from text or html, and extract pages.
Picture 7. All PDF Tools (lite) Menu and Features

All the free features I've been tried, and it conclude that every features are promising. But, only the merge pages or pdf documents I still haven't hack into it in these lite version, same like the others we can't inserting an image onto pdf document.

Conclusions 

From all the three free Android apps to edit pdf document, I love the way things with Xodo, but with some features that PDF Max Free offers could covered the Xodo lost capabilities, even from lite version of PDF Tools apps.

So in the end, I end up with all those three apps just to edit some pdf. But wait, what about inserting an image to document? I still to find another Android pdf editor that worth of money. Do you have any idea what pdf editor on Android Smartphone are capable of doing that? Give me some feedback, if you have one. Thank you.


notes:
All images editing in these post are conducted on Android Smartphone Xperia Z with Lollipop using Photolayer and Image Editor

Microsoft Office for Android Smartphone (at last) on Xperia Z


Overview

Microsoft already a year ago turns their products running for mobile, but only for simple editing and compatible with Office 365 subscription.

Figure 1 Microsoft Office Mobile Apps for Android

Microsoft still try their best to reach out mobile users, especially when they already has mobile phone platform to begin with. The products update on Android users available limited only for phablet or devices comes with 7” inches and up display.
Even though Android platform is one of their market competitors, but the users is one of those opportunities to reach in. Using Microsoft Office products and Cloud Computing SaaS to strife other platforms and still able to wins their heart of using Microsoft products.
Enough said for how Microsoft gain their profits using their software plus Clouds, it’s time to see their own product for Android smartphone device, which no longer on beta version or invitation only bug finders. The Office apps is already on Android Google Play Store and comes with specifications are any smartphone that running Android Kitkat 4.4.4 or so with plenty of space on internal memory, writer recommended minimum 4GB free space, and 1GB of RAM for running one of the apps.
Another thing to keep in mind, to use most of Office apps features you'll need Microsoft account and pay the subscription to use full features. But, Office apps itself is still able to use to open and simple edit, if you don’t have Microsoft account.

Figure 2 Microsoft Office for Android Smartphone and Tablet with 4.4.4 or up Versions

We could find the apps for smartphone on Google Play Store, where before we hardly found it or can’t install without any invitation, to used and test it. Each of apps comes with different sizes and in the process of installation, we also have to download additional file first. This additional file making the apps become bloat, but these are needed to provide high performance apps and using low resources.
 
Figure 3 Comparisons File Size Before and After Installation

Microsoft Office main apps itself comes with 3 (three) major office productivity application, which are Word, Excel and PowerPoint, even though there are other apps we could found in Google Play Store like Outlook, Office Lens, and One Note. Our first initialize of those three apps, a splash screen with intro page before we need to input Microsoft Account. Then, on first screen we’d offer to start using or upgrade service with our Office 365 paid subscription account. If you want to start using it, prepare to sign in first with Microsoft Account.

Figure 4 First Time Initialize of Three Microsoft Office Mobile

  
After we setup and configure using Microsoft Account, we could see our files list has been arrange time modified sort. Either on cloud storage like OneDrive, Dropbox, Google Drive, etc or inside our device. The file that Word could handle, right now limited to .doc or .docx file only, because my .rtf, .txt, and odf file aren’t on the list and Word never asked me which kind of file type that need to associated and file type to be working with Word only with .docx. While Word could handle .xls or .xlsx file only and save to .xlsx, and PowerPoint handle file with .ppt and .pptx extension and save to (you could guess it, yep) .pptx extension.

Word

The first one is Word, just like Microsoft Office Word available on PC or Mac, these one is the mobile version of the original one. The main functionality is to create a document for people productivities, like making reports, journals, notes, books, letters, etc. Word provide with many kinds of template that we could be used to initialize our work without many efforts just to format it like they need to looks like.
Next on apps, the UI almost feel like using Microsoft Office 2013 Web version or online version, but condense or comprises onto single format button. Main menu button presented by three bar stacked on upper left corner, followed by format and styles button, reflow view button, save file button, share button and undo button on other end in same level. The difference between those two, beside button, there’s reflow text function. What’s this function anyway? Like the other Office apps, Word is capable to adjusted display text input to make users comfortable working with this apps.

The compliance between Office Word for Android Smartphone files and PC or computer version files is perfect. These means that if you want to continue working your documents on Computer to your Tablet or Smartphone would be no problem and even if you want to continue working with your documents seamlessly, just connected with OneDrive account.
All features on Word Online is available on Word for Android phone, but not all of these features are able to used, except insert references. Even with Microsoft account connected, you'll need paid subscription to Office 365 account. Sadly to said, features like page orientation, page break, and columns only available to paid subscription users.
Microsoft Word for Mobile is indeed a powerful apps for productivity, I’ve been tested to use these apps several days. For some reason with Sony Xperia Z resource using Lollipop, Word is always re-open the file that I’ve working on, while switching to other apps. I don’t know whether this is the default operation, but looks like Word only works with 1 (one) apps window, that happened too while I tried to opened second Word file. While inserting shape or text box isn’t a big deal to Microsoft Word, but different thing applied inserting image. I tried inserting an image, but there isn’t any result that indicate the image is inserting to Word page, I already send a feedback to Microsoft Developer to fix this.
Handling many pages or thousand characters or even thousand words is not a problem, even not made apps crash or lagging on performance. But keep in mind that only occurs with print flow text. Different if you on re-flow text you’ll find lags on typing, this occurs when document reach more than 15 pages. Not only for typing, includes insert table, shapes, and other kind of formatting.

Excel

Microsoft Excel is same with previous Microsoft Office apps, you able to use its feature with your Microsoft Account. After a few minutes to setup and login your Microsoft account, then Microsoft Excel available to used it.
Not like Word apps, on Excel apps every features are available to be used free with Microsoft Account integration. Microsoft Excel not having reflow text button, I have open many type of Excel files to test how the apps could handle everyone of it. Start with blank workbook, using the Excel template, open file with a thousand or so lines, open with more than 10 worksheets, with many pictures or charts, and even creating chart with more than two thousands line of data not even glitch or sluggish feeling.
This is incredible, really, magnificent. I had some lag with another Office apps while opening file with four thousand-ish line of data, or creating several charts with a thousand of data. But, then again same like Word, we could only work with a single file and not able to insert an image, not even smallest pixel of an image (120px x 120px).

PowerPoint

Well, now the last Microsoft Office apps, the Microsoft PowerPoint. The one that created a presentation show on line of Office application in Microsoft. Same with all, for the first time we need to sign in to Microsoft Account before using with all features.
How you using this apps is up to you, but on my opinions and I prefer using on portrait mode, why? Because on portrait mode, we still could see part of text or area that we edit or insert it. While on landscape, most of it will be covered up with keyboard.
Same with Microsoft Excel, PowerPoint does really know how to handle the job pretty well with all features and menu all could be access and used. Try to opened presentation file with 20 and more slides with pretty much of image inside it, there’s no lag on apps. Even, open a file with 4MB-ish file had no problem. The euphoria seems to be stop with unable to insert an image onto slides, I still don’t know whether still mere hardware problem or still need work to do from Microsoft itself.

Conclusions

Microsoft know their product and how to handle it, because I’m amazed with how the apps is work, and whatever we’ve been working on Mobile it’s formatted exactly on Computer. The OneDrive itself gave advantages to be able working on any devices or any platform, and save our work anytime and anywhere, convergence they said. Google drive or Dropbox is the same as cloud storage, made our work is accessible from any devices or any platform, but the compatibility could be some issues.

Sony Xperia Z Pengalaman Awal Menggunakan Android Lollipop

Berdasarkan pengalaman pengguna dalam menggunakan smartphone Sony Xperia Z setelah upgrade firmware ke Android Lollipop.


Pengalaman menggunakan Android Lollipop dalam 34 jam di smartphone Sony Xperia Z tipe C6603 dan merasakan perubahan pada tampilan, performa, fitur-fitur dan daya baterai. Pertama-tama yang ingin diberitahukan kepada pemilik smartphone Sony, bahwa Sony tidak memberikan notifikasi kepada pemiliknya melalui system update. Saya sendiri mengetahuinya setelah tidak sengaja menjalankan apps Xperia Update. Ketika apps tersebut berjalan dan saya melihat pada tab System terdapat 1 update.
 


Informasi tentang update ke Lollipop tertulis pada apps tersebut, kita memerlukan ruang kosong sebesar 1,2GB pada memori internal smartphone dan membutuhkan aplikasi Sony PC Companion untuk mengunduh dan memasang firmwarenya. Setelah beberapa waktu untuk mengunduh, memasang, dan optimasisasi apps kemudian reboot lalu tampilan Android Lollipop pun muncul.


Tampilan
Yang pertama kali terlihat adalah kotak notifikasi pada layar kunci, sebuah fitur baru dan awal pertama kali yang terdapat di Lollipop. Pada halaman home terlihat ukuran icon apps yang telah berubah sedikit  lebih besar daripada ukuran pada versi Kitkat. Ketika tidak sengaja saya merotasi smartphone, secara otomatis layar utama pun ikut berotasi, walau Sony Xperia Z tidak berada pada charging dock. Menurut beberapa pengguna Sony Xperia tipe Z1 dan diatasnya, fitur ini baru ada pada Sony Xperia Z, apakah ini merupakan sebuah penghargaan bagi Xperia Z? Smartphone flagship pertama yang mengusung segala kelebihan seri Z.


Tampilan yang berubah secara drastis adalah area notifikasi dan setting shortcut, recent apps, tiga tombol utama Android, dan tampilan material desain yang terlihat sekali di tiap halaman. Kontak dan pemutar telepon juga mengalami perubahan, yaitu pada ukuran font yang sedikit lebih besar dan telepon yang sering dihubungi terdapat di bagian atas layar, sedangkan perubahan lain pada apps jam dan alarm yang tidak lagi terlihat kaku seperti pada versi Kitkat.


Perubahan yang terjadi pada versi Android Lollipop, selain pada tampilan juga pada bagaimana cara pemilik smartphone berinteraksi dengan Android. Perubahan desain secara keseluruhan pada Lollipop merefleksikan Android menginginkan bagaimana seharusnya kemampuan smartphone seharusnya.


Performa
Setelah 38 jam penggunaan Android Lollipop sudah cukup waktu untuk menilai performa dari smartphone Xperia Z. Saya sendiri tidak melihat adanya penurunan performa sebelum dan sesudah menggunakan Lollipop. Sehingga saya coba memberikan nilai dengan menggunakan Antutu dengan segala apps yang telah terinstal di smartphone saya. Tes dengan menggunakan Antutu dijalankan dengan kondisi baterai Xperia Z terisi penuh (atau sekitar 99%), tidak ada apps yang berjalan atau yang telah dijalankan, berdasarkan pada recent apps yang kosong dan boot-up pertama setelah pengisian baterai. Seperti yang sudah terdapat di daftar hasil Antutu, Sony Xperia Z dibandingkan secara dekat dengan Asus Zenfone 5, dan hari ini hasil skor tes lebih baik dari Zenfone 5 yang menggunakan Kitkat.


Saya tidak menemukan adanya bugs ataupun lag dan berjalan dengan baik pada Sony Xperia Z C6603. Menjalankan dan menghentikan setiap apps, baik secara individual atau secara bersamaan antara 4 sampai 7 apps pada recent apps. Bahkan memainkan game Marvel Future Fight dan Modern Sniper secara bersamaan, berpindah-pindah antara kedua game tersebut dan tidak terasa adanya bug atau force close. Yang lebih menariknya adalah setelah menghentikan sementara dalam gameplay (game paused) dan memainkan kembali, tidak terdapat lag yang saya temui saat menggunakan Kitkat.
Kembali saya lakukan percobaan mengenai performa Lollipop, kali ini saya menjalankan game Marvel Future Fight bersama dengan WPS Office, Google Drive dan Google Chrome browser dengan 5 tab laman web yang terbuka. Berdasarkan pada Kitkat, dengan kondisi seperti ini akan mengalami penurunan performa pada game atau lebih parahnya game dapat saja restart, ketika game tersebut pause saat pindah ke aplikasi lainnya. Ternyata hasilnya seperti yang telah saya duga, bahwa game tidak mengalami restart ataupun mengalami lag setelah pause dan pindah ke apps yang lain. Hal ini juga mungkin karena Android telah menggunakan runtime engine terbaru yaitu arsitektur ART.
Sepertinya performa smartphone memang mengalami peningkatan, sesuai dengan skor pada Antutu Tes.


Fitur
Cukup dengan performa dan tampilan, Android Lollipop sendiri bukan sekedar upgrade tampilan. Saatnya berbicara mengenai setumpuk fitur yang terdapat di Lollipop.

Notifikasi
Bar notifikasi yang terdapat baik pada layar kunci utama atau pada laman notifikasi yang terdapat di atas layar, telah mengalami banyak perubahan daripada versi sebelumnya. Terutama pada layar kunci smartphone, belum pernah ada pada versi-versi sebelumnya secara default. Walaupun beberapa custom ROM atau custom launcher lainnya dapat mengakomodir, tapi tidak pada stock ROM ataupun bentuknya seperti yang terdapat pada Lollipop.


Kotak notifikasi pada Lollipop juga mengalami banyak perubahan, notifikasinya telah terkelompok sesuai dengan apps yang sedang berjalan. Walaupun fitur ini juga telah terimplementasi pada versi Kitkat, akan tetapi ada sedikit perbedaan pada setiap notifikasi tersebut terdapat pengaturan lanjut, dengan cara menekan dan menahan salah satu kotak notifikasi sampai terlihat icon huruf 'i' dan menekan icon tersebut. Pada jendela berikutnya akan terlihat pengaturan untuk notifikasi dari apps tersebut, apakah kita akan memblokir atau membuat prioritas terhadap notifikasi.


Prioritas notifikasi
Selain pengaturan terhadap notifikasi terdapat langsung di kotak notifikasi, tetapi kita dapat mengakses pengaturan tersebut melalui menu Setting di laman all apps, yaitu Setting > Sound and Notification > Apps Notifications akan menghasilkan fungsi yang sama. Pengaturan tidak hanya berdasarkan pada tiap apps, notifikasi diatur berdasarkan dari kontak orang. Pada laman yang sama, kita juga dapat mengatur gangguan atau interruption atas telepon yang masuk, acara dan pengingat, bahkan pesan dan kita dapat mengatur kotak orang yang dapat senantiasa menghubungi tanpa gangguan, apakah semua orang (tanpa pengaturan), yang terdapat pada kontak saja, atau bahkan kontak favorit saja.


Tidak hanya itu saja, fitur interruption dapat diatur sesuai dengan waktu yang kita inginkan, sebenarnya fitur ini dapat di atur juga melalui aplikasi Sony Smart Connect, tapi jika menggunakan aplikasi ini mengatur seluruh sinyal seluler atau hanya mobile data saja yang di non aktifkan ketika terhubung baik dengan perangkat pengisi daya, dock, NFC tag atau aksesori lainnya.


Layar kunci (lock screen)
Seperti yang telah saya ungkapkan sebelumnya bahwa layar kunci di awal pada Lollipop telah berubah, tidak hanya hanya penambahan pada kotak notifikasi, tapi juga akses langsung ke pemutar telepon yang di indikasikan dengan icon telepon di pojok kiri bawah dan di geser diagonal ke atas kanan atau akses ke kamera dengan cara yang sama tapi kebalikannya dari pojok kanan bawah di geser diagonal ke atas kiri, selain itu jika untuk membuka kunci dengan menggeser layar dari arah bawah ke atas.
Setiap notifikasi juga dapat di akses secara langsung dengan cara tap dua kali pada notifikasi yang kita ingin lihat, atau tap sekali dan geser ke bawah untuk melihat secara sekilas isi dari notifikasi tersebut. Kita juga dapat mengatur isi dari notifikasi tersebut akan di tampilkan pada layar kunci atau tidak, hebat kan?


All-in-one Tabs
Fitur seperti ini mungkin diinginkan oleh orang lain, tapi tidak untuk saya. Android versi Lollipop memberikan fitur ini sehingga tab Chrome browser atau tab browser lainnya dapat di akses secara langsung melalui fitur recent apps. 

Anda dapat memilih kembali atau menutup secara langsung tanpa harus masuk melalui browser. Setelah beberapa jam mencoba fitur ini, saya masih memilih recent apps tab hanya untuk recent apps dan tab chrome berada tetap di dalam aplikasi browser.


Multi users dengan multi desktop
Fitur lainnya yang telah di tunggu lama, Lollipop memperkenalkan penggunaan banyak desktop pada smartphone. Yang mungkin belum ada adalah seharusnya aplikasi yang telah terinstal seharusnya dapat ditentukan, apakah akan digunakan atau terlihat di semua pengguna, yang terjadi setiap pengguna memiliki aplikasi miliknya tersendiri.
Fitur ini dapat diakses lewat notifikasi yang berada di atas layar dan di tarik ke bawah, kemudian tap gambar foto pengguna. Cara lainnya adalah dari Setting, pada menu account > new user account, pemilik smartphone dapat memberikan akses kepada orang lain yang bersamaan menggunakan smartphone tersebut, tapi akses terhadap pengaturan perangkat keras tetap berada di pemiliknya.


Baterai
Hampir dua hari menggunakan Lollipop, baik menjalankan berbagai aplikasi, browsing ke internet, sms, pesan instan, dan telepon, perangkat Xperia Z pun menghasilkan panas yang cukup terasa di genggaman. Hal ini seringkali terjadi saat melakukan perambaan internet dengan membuka 4 tab atau lebih. Pada versi Kitkat, jika hanya ini kondisinya panas dari baterai tidak terasa seperti saat menggunakan Lollipop ini.
Tapi panas seperti ini tidak terjadi, jika hanya menjalankan aplikasi Office, email, dan game yang saya install, utility apps atau telepon. Cukup aneh kalau menurut saya, selain dari itu umur penggunaan baterai antara dua versi firmware tidak berbeda jauh. Dalam penggunaan normal saya menghabiskan baterai dalam waktu sekitar 7 jam saat menggunakan Kitkat dan saat ini pun masih sekitar itu juga. Saya menggunakan WiFi pada hari dan jam kerja, dan mobile data (4G/LTE atau HSPA) selain waktu tersebut.


Selain dari isu penggunaan baterai dan sering kali orang lupa untuk paparkan adalah berapa lama waktu yang diperlukan untuk mengisi daya baterai hingga penuh? Setelah tiga kali melakukan pengisian daya baterai, Android akan menampilkan status pengisian dalam persentase saat ini, ketika dalam keadaan mati dan berapa lama waktu yang di butuhkan hingga baterai terisi penuh dalam jam/menit saat kondisi hidup.
Saat pertama kali menggunakan / update ke Lollipop, dari kondisi 16% baterai yang tersisa membutuhkan waktu 1 jam 44 menit untuk terisi penuh. Pengisian yang kedua dari kondisi baterai habis dan mati, membutuhkan perkiraan 2 jam 6 menit, dan terakhir kalinya mengisi daya Sony Xperia Z saya dari daya baterai tersisa 8%, membutuhkan 2 jam 2 menit sesuai tampilan di layar. Saya rasa walau terasa sedikit lama dari sebelumnya, tapi kenyataannya waktu yang dibutuhkan hampir sama.


Kesimpulan: Keanehan dan Keunggulan
Masih banyak orang melaporkan bahwa perangkat smartphone Xperia mereka (Z3 dan Z2), ketika menggunakan Lollipop mengalami banyak error atau bugs, tetapi kenyataannya saya tidak (atau belum) mengalaminya. Hanya mengalami sering panasnya baterai, selain itu animasi dari notifikasi atau shortcut setting dari atas layar terkadang terasa agak tersendat, dan ketika berpindah apps ke game yang sedang berjalan tampilan game tertampil sesaat menjadi setengah layar dan beberapa detik kemudian normal kembali.
Keunggulan Lollipop sendiri yang telah saya rasakan, apps / aplikasi berjalan dengan cepat, respons dan interaksi terhadap smartphone juga lebih baik, tampilan layout UInya terasa nyaman, dan yang paling saya inginkan adalah fitur multi desktop. Yang herannya, para kompetitor telah mengimplementasikannya, mengapa Android belum memasangnya, hingga sekarang terjawab pada Lollipop.
