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

  1. Home

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.

Searching Google for the com.google.media, the advice was to search /mnt/sdcard/media/audio/ for ringtones and delete them. I did not have any ringtones there, but did have one notification for facebook. I deleted it, and it helped a bit.

After that com.google.media continued to eat CPU time.

Only after I killed Xperia Gallery using Automatic Task Killer (ATK) did the phone go back to normal, and neither com.google.acore nor .media were eating up CPU.

Here is the output of top -n 7, either from adb shell or from ConnectBot.

While com.google.media is eating CPU:

User 55%, System 12%, IOW 32%, IRQ 0%
User 56 + Nice 116 + Sys 38 + Idle 0 + IOW 100 + IRQ 0 + SIRQ 0 = 310

While both com.google.acore and com.google.acore is eating CPU:

User 83%, System 10%, IOW 6%, IRQ 0%
User 40 + Nice 214 + Sys 33 + Idle 0 + IOW 19 + IRQ 0 + SIRQ 0 = 306

After com.google.acore stops eating CPU, the output was
