ATT version of SG2 sucks your battery?! *Fixed*
Update and FIX!
My phone is no longer draining massive amount of batt life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.
1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory
Yes, att installs a lot of bloatware that constantly update for changes.
If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:
1. Take phone back to att and get a replacement
2. Re-flash your android with the STOCK kernel
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).
NOTE** This will root your phone, you will NOT get the exclamation mark during boot up, but kernel counter may be at "1" after this process.
Re-flashing my phone AND applying the three tricks I mentioned above worked for me..finally my phone is no longer crippled with crappy battery life and recharging is A LOT faster now.
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).
The phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files syncing from time to time (but 2-3% usage usually).
Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.
It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.
I see people who have a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
Running on 2.3.4, can't be the infamous drainage bug right? Thought that only happens with the 2.3.3s
Wifi on, application sync on, GPS off, brightness at 25%, using live wallpaper (the windmill). No active apps on. Downloaded aim, epocrates, battery monitor, cpu spy, and os monitor..rest of the apps are stock.
According to my CPU spy
For the past hour that the phone was in idle
2:20mins at 1200mhz
4:52mins at 1000mhz
8:33 at 800mhz
1:28 at 500mhz
10:11 at 200mhz
33:36 in deep sleep
Currently Android CPU usage is @ 97%, display time of 7mins(2%)
2h 30mins since last charge (97% charge)..current power is 79%. Did nothing but idling and checking battery life.
So...that's 30 mins out of the hour in which my idling cellphone was hacking the pentagon....
Also the cellphone is a tiny bit warm to the touch (not cold)
