[XPERIA X10 General] aBaDDoN-NL:
First of all, normally I'm not quite the chatter :)

But I've been browsing the X10 related topics on the XDA forums for a while now and especially those related to batterylife.

Last Friday I decided to finally take some time to figure this battery usage of my X10. This is I my first Android phone (waited a long long time because after the first "leaked" images of this phone I was sold :D ) so I took the time with several tools/apps and tried everything I could think of to decrease the powerusage of my X10. And I found the culprit on my device finally and wan't to share this with you guys. Maybe you'll be able to find the culprit on your device.

After purchasing the X10 I had to do two or three full battery discharges to get some more juice out of the battery. Batterylife went from 8 hours to approx. 20-24 hours.

I've tried severel tools like Advanced Task Killer (Free version), Juice Defender (almost decided to go for Ultimate Juice), TasKiller, Task Panel to kill processes when the weren't needed. Task Panel worked best for me when I wanted processes/apps to be killed the moment my screen was turned of.

But my phone wouldn't last for more then 20 tot 24 hours with an light to moderate usage (30 min to 1 hour call time, 20-30 textmessages, 30 minutes browsing, 1 hour playing around with the device, 30 GPS with google maps, 1 hour music). Ok, don't think there is a real definition for light, moderate or heavy usage so this is how I defined it for myself.

Then I read in some thread about the application Spare Parts and downloaded this from the market. I noticed that my phone never went to sleep and kept running at 100%. I tried to kill all kind of processes with the above mentioned tools but it would help. Even after removing widgets (not actually uninstalling them) and switching over to Helix Launcher 2. I installed OSMonitor and couldn't find a process that was eating cpu-time.

I was almost accepting the fact that my battery just wouldn't give me more juice to run, but couldn't accept this because I read posts of people running more than two days on the same battery.

So I started to just simply do a step by step procedure using two applications only. I removed all task managers/killers from memory and bought ( 1 dollar worth the shot) /downloaded Startup Auditor. Together with Spare Parts I simply started to check the usage.

First I disabled all programs entirely until only basic processes where left. Rebooted the phone and waited a while (15 to 30 minutes). Then started up Spare Parts and checked "running" percentage at "Battery History", "Other Usage / since last unplugged". I saw it dropping drastically.

This was a clear sign for me that something was really eating up my battery because normally it ran at 100% and my remaining battery percentage didn't drop a thing (maybe ~1% while normally it would drop 5% every hour).

So basically I started this process all over after enabling 2 to 4 apps. Enable them, reboot the phone (just to be sure), wait a while and check the percentage running.

Eventually I discovered it was the Beautiful Widgets Home widget. After enabling it my phone was running 100%. Not Timescape, the face recognition service etc. Just the widget I downloaded almost at day one.

I've still have it disabled, running

- widgets: Timescape (updating Facebook every hour, Twitter every three hours), BatteryTimeLite, Digital Clock, Calender

- home: Helix Launcher2 with 5 screens

- 3G: turned on always

- Brightness: auto

Same usage as always similar to described above...

Battery at 60%, device up and running for 32 hours.

In my case this increased my battery life with more then 200%. It won't guarantee that all of you will be able to find the culprit on your device, but hopefully it will help others. If this will be multiplied by a factor x due to the upcoming Sony update then it would be super (mind though that I do not expect it to double battery life, maybe a better way of handling processes or whatever).

So here is my first post and 50 cents to this community ;)

Ps. when the device starts roaming when you don't have networkcoverage... It sucks your battery like hell. Noticed a 2 to 3% battery drop just being 20 to 30 minutes out of network coverage (a shop with some sort of force field around it probably :P).
