By going through forums and blogs, there are no answer for this issue yet, but some possible reasons stated are:
i) hidden services running behind
* no matter on off data traffic (WiFi/3g)
ii) Camera app
* once run camera app to take picture, it will continue running behind
iii) New Batt takes some full time cycles charge to work at its peak
*drained three times and fully charged, still doesn’t help
Next, i done a small test to make sure mine is not fault unit,
Step 1
- Turn off all auto sync
- Stop Camera app by going into “Running Service” -> tap on free RAM at the bottom right with light green color -> Scroll and choose Camera -> Tap to stop it.
- Put on the battery widget that comes with ARC, it helps me to monitor battery percentage
- Uninstall advance task killer, there is still debate on whether it really helps
- Turn off GPS, Data transfer, WiFi and Bluetooth
Step 2
- Reboot
- Charge more than 5 hours
- Monitor
Monitor log:
14 hours, 91%
- idle for 9 hours as i am sleeping
- few msgs, alarm, miss call, check
- check on the running service and battery percentage for few times
1 day 2 hours, 81%
- half an hour music playing
- few msgs
1 day 15 hours, 69%
- 3g for 45 minutes
- music playing for 15 minutes
- working on Evernote few times
- few msgs, alarm
1 day 22 hours 39 min, 61%
- WiFi for 10 minutes
- Transfer 1 music album through WebSharing
2 days 3 hours 18m, 47%
- 2 msgs
- 40 minutes music playing
- 10 minutes 3g for ESPN, Download and install WordPress app
2 days 9 hours, 34%
- 3g for update Adoebe Flash 10.2 and Whatsapp
- Wifi for 15 minutes
- 3g for 15 minutes on surfing blogs
- take pics with Camera 360 for around 5 minutes
2 days 15 hours 14 min, 7%
- took around 20 pics with stock camera app
- few pics on camera 360
- an hour wifi
- 10 minutes 3g
-
2 days 16 hours, 0%
- arc auto shutoff
*not making any phone calls in this test
Conclusion:
From the testing, it is obvious the battery unit is okay. I have no clue to point out which app or service that “sometimes” draining battery. I hope to have full access to system log.
My guess on two possibilities:
a) Incorrect battery charging measurement
For example: 100% on battery status actually is around 75% at that time. Therefore, it drain fast when using it. If this is the one, then charge it for a longer time although already 100%.
b) Apps or services running behind
If this is correct, temporary solution is reboot it when you figure out the phone drain around 7%-10% for an hour, with phone mostly idle or light use.
*Hopefully the coming Sony Ericsson official update will solve it.
Update: 2.3.3 update fixed battery drain issue.
