Solutions for Android battery drain because of suspend_backoff/Wakelocks

Contents: 

Tags: 

If your Android phone is suffering from suboptimal battery life, you may be suffering from suspend_backoff problems. This happens when the phone is woken up by applications in quick succession, so it decides to keep the phone awake for a little while. For example, there is data to be sent over WiFi, so the WiFi connection is kept awake, which keeps the phone awake.

High CPU usage on Sony Xperia Arc with Android Ice Cream Sandwich 4.0

After I upgraded my Sony Ericsson Xperia Arc from 2.3.4 (GingerBread) to 4.0.4 (Ice Cream Sandwich), I noticed that it was laggy and slow.

With Gingerbread 2.3.4, and ADW Launcher as the home screen, everything was fine.

Upon using the "top" command, either from ConnectBot, or from adb via the USB case, I noticed that com.google.media and com.google.acore are eating up most of the CPU time.

You can also go into Settings Developer Options and turn on the CPU overlay which will tell you the top processes eating up CPU.

Do you have a Sony Ericsson Xperia phone running Android? Such as the Xperia X10 or Xperia Arc? Is it slow and lags often?

We have a solution for you ...

But before we tell you, we have to explain why Sony Ericsson's Android can be slow. The reason is Timescape, Sony's user interface for Android phones. Even if you disable all the Timescape widgets from your home screens, it will still be running under the hood.

Arabic on Sony Ericsson Xperia Arc and X10 running Android

A very nice surprise from Sony Ericsson. Even though Android does not have full and official support for Arabic until Android 4.0, their handsets do have very good Arabic support by default, even handsets sold in the USA and Canada.

Arabic in Sony Ericsson Xperia Android phone

If you have Android 2.1 or 2.3 and updated it to the latest update from your carrier, then you do have Arabic support. To check if it works, then just visit BBC Arabic and see if Arabic shows correctly and the letters are connected.

Enabling Arabic keyboard

To enable Arabic typing, you need to press Menu, then select "Language and Keyboard", then under "Keyboard settings" select "Default input", then select "Writing Languages", and check "Arabic". You will then see a language switching icon on your keyboard (the "globe" symbol).

Not only does Arabic work well, the font looks much better than what is in CyanogenMod for example.

How to root a Motorola Milestone and Sony Ericsson Xperia X10 and enable Arabic on them

Update 2011-09-02

For the Xperia X10, when upgrading the software using Sony's PC Companion, you will get full Arabic support on the phone, with a beautiful font, and no glitches. The only drawback is the phone is unrooted, and therefore you lose functionality of apps that require root (e.g. Titanium Backup, ShootMe), and have the bloated apps that autostart (Timescape, Moxier Mail, ...etc.)
