i have i9100 which was on 2.3.5. i did something stupid with it and rooter my phone ,upgraded to RR JB Rom with Siyah kernel. Since then my phone was very cranky. the battery used to drain down very fast. read a few threads and turned the wifi off when on sleep, never went to 3g network and i used it only for phone calls and msgs but it still wouldn't stay longer than 3-4 hrs before the battery drains.
a little later to add to my misery, the phone used to shutdown randomly. each time this happens i connect the charger and power it on. when the charger is connected, the battery shows 80% but when removed phone shuts down.
i tried to re-calibrate the battery going to recovery mode nogo.
so i decided to downgrade to ICS. i am now on an official ROM by Ssamsung for S2. Un-rooted the phone. same issue here as well. i open you tube , Fb, Dolphin Browser, the phone shuts down. i think this is happening only when i use internet.
i don't see wipe battery stats at all now in recovery mode to re-calibrate my battery.
i am stuck and need help. very close to throwing this phone away and settling with a cheaper one. please help!!!!!!!

I just noticed in the past few minutes that my gmail is pushing to my tablet despite the screen being off and my wifi policy set to off when sleeping. I've also found some issues when it would actually cut the wifi off when sleeping, and when it comes back it doesn't want to reconnect to my router.
My other issue is battery life related. Last night I *believe* I turned airplane mode on before going to sleep and when I woke up 9 hours or so later, the battery was at least 10% down, I think more than that but I didn't take note of it at night. Even if wifi was on, it should've been shut as my sleep policy is that way. Looking through other threads people seem to be experiencing 1% or so battery drain in an hour. The other factor is that I have setcpu installed and a screen off profile that maxes at the second lowest frequency. This morning I installed netarchy's kernel and lowered my setcpu profile so it stays at the minimum frequency when the screen is off.
I'm running Prime 1.3 (didn't do the r2) and have manually removed a handful of the Asus apps that I don't use/want, and I have GPS disabled.
What 'concerns' me is that I have a droid incredible for a while now and with it, I get no battery drain overnight with airplane mode on (at least none that registers) and that's a battery with a fraction the capacity of the transformer. Moreover, I have a very few apps on my tablet whereas my phone has quite a few and basically beyond the stock stuff on the tablet the same apps are on my phone. Also, the battery stats window on the transformer doesn't show any info about apps. I've had my phone on since I woke up, on 3g and I'm at 90% with not much use. And I thought that my phone got meh battery life.
ive had some issues with wifi disconnecting and wouldn't stop disconnecting till a reboot. cant find any news on it. ive tried all firmwares now and still have the issue.
I been having the same issue. Last night I reflashed the 8.2.3.13-20110511 build, to see it it will help. Mine is stock not rooted.
I have the dock and use the pad with most of the time, both are loosing battery life even after I do a complete shutdown. To me it seems it has gotten worse after the 8.2.3.13-20110511 build update. The WiFi is loosing connection when the dock goes dead so I have to reboot the pad to get it to reconnect.
I also have contacted Asus tech. On another thought I really wish in Android you could disable startup apps without rooting.

Was hoping for more replies but my naturally long-winded posts probably scared everyone off...
I wiped my device and installed Modaco's ROM. I didn't touch the stock apps and only things I've installed are Titanium & Tasker. I put together a Tasker profile to kick airplane mode on when the system is put to sleep, and turn it off when unlocked (unless airplane mode was enabled when put to sleep). I also installed Setcpu and setup a profile to keep the CPU frequency to the minimum when screen is off.
I charged to 100% and let it sit overnight. When I woke up I was at 98%, when I got home a little while ago it was at 96%. Note that I hadn't used the tablet other than for a brief minute or two to check the battery stats. As of now I'm showing 15hrs 51mins on battery with a 4% drop. I've had it in airplane mode the whole time. Oppositely, I had my droid incredible at 100% and played Drop7 (great game btw) for at least 20 minutes before going to bed last night, and it was still 100% when I woke up (it was in airplane mode overnight). I find it weird that my droid incredible, with a 1/4 of the battery capacity doesn't drop at all overnight even with a game being played, and the transformer drops 2% in that time idling.
Has anyone wiped battery stats via CWM?
When I setup AutoStart, I noticed the power state event for screen on/off is off by default. I tried turning back on, seems to improve battery on sleep.

Ok I have searched and not found anything like this yet so I am going to ask. I know the phone has battery problems all around for a lot of people. Mine seems to be fine when it is on. It can sit and idle powered on all day locked and stay at full charge. It runs about 10 hours with minimal use and maybe 8 hours with some data use and a few calls and texts. Now I am experiencing a wired problem. When I go to work we cannot have cell phones. I leave my phone in my locker and power it off. After my 12 hour shift is up at work I come back to the phone with a dead battery? What could be causing this? And has anyone else noticed this issue?
defective battery? pull the battery and see if it still does it. If it does, gotta be a defective battery.. if it doesn't do it when pulled, you're not shutting off the phone maybe?
Yesterday I tried leaving the battery out. I took the battery out and let it sit 12 hours and it still had full charge when I put it back in. When I go to work I long press on the power/lock button and choose Power off then I watch it shut down and it just dies before I come back. I wish I could watch it the whole time. Today I left the phone off for around 6 hours and came back and it was fine though. Maybe it gets turned on some how at work. I have no idea. Or when I go to power it on it is just the issue where the phone isn't reading battery % correctly and it just says 0%
Seems like a battery driver issue or a defective battery? definitely call t-mobile and check if it's the battery. I've had some issues as well, but not that bad.
Weird.
So the phone powers off after you turn the screen on and it won't come back on? Try putting the phone in airplane mode.
Also, I'm assuming you are running the stock roms?
Might also want to check into a battery monitor to see if any 1 thing is pulling it down.
I think it might just be the battery driver. Sounds like the phone is in suspend so it doesn't power off properly until the screen is turned on and is revived, updating the battery % status, seeing 0%, and turning off.
CM7 fixed the wonky battery issue a few nights ago. Right now, I think a current CM based rom is the best bet as it has most of the drivers fixed. I'ved used mine pretty heavily today, unplugged at 8am and I just got a 15% battery warning at 11:30pm. It will usually last until I go to bed at midnight but I might want to play with it some more.
Well, this was interesting... Since day 1, I have had great battery life and have not experienced what everyone else has been experiencing.. An occassional lock-up/reboot, but nothing major.
A couple of weeks ago, I switched to a backup battery (andida). Things have been going well w/ that battery. Yesterday, I updated cwm.. While the andida battery was out, I decided to switch back to the stock battery for a while. Then, the following items took place all within a few hours of use, which I have not experienced.. ever before:
- Battery temp running high.. Andida constantly hanging around 22.2 - 23.2. Stock was hitting around 43 until i rebooted the phone, then dropped to 40. It is currently running at 36.
- 2 shutdowns. I could not boot the phone past the LG logo after the shutdown. Was able to boot into CWM though > went to shutdown > tried to boot, same thing. Had to pull the battery in order for it to boot.
- Received a phone call, answered, but the phone kept ringing during the entire phone conversation.
- 2 screen lockups. Could slide the unlock, get the haptic feedback, but that was it. It would not unlock. Had to reboot.
- 1 black screen of death? Total black screen with the task bar displayed. Was able to go into settings, pull down the task bar, etc. Background was blacked out. Reboot, fixed.
- Can not get gps. Was driving for 5min trying to get a GPS lock, nothing. Opened up GPS test and not a single satellite showed up in the list.
- Finally... and worst of all. Last night I plug in the phone for a couple of hours. As I'm going to bed, I disconnect the usb from it.. and take a glance to see where it charged to - 100%. I go to bed at around 1:30am. I wake up at 7:30a, turn on the screen of the phone, and it gives low battery warning. It's at 2%. I reboot the phone to make sure. It's at 1%.
So idk.. maybe something was stuck running. I'll find out here shortly after this charge is done.. but I am seeing a major difference in the operation of the phone after putting the stock battery back in. I had not experienced this when I was running the stock battery in the past. (I had an occasional lockup/reboot.. but not to this scale.. and I had always had fantastic battery life. Every single time I unplugged before bed and had 100%, I would have 98% when I woke up).
Suggestions? Changes were updating to the new CWM 4 and putting the stock battery back in. Running Bionix RC1..which I have been running for a while. I'll let this sucker charge up and see what it does. Maybe I should wipe the batt stats?
yeah wipe the batt stats. possibly try cm7 its really stable now. i know it doesnt have the a2dp but every else works. i would say another kernel also faux's or morific work fine. use setcpu if your going to oc. if you choose to flash another i would do a complete wipe of everything then install so hopefully the problems wont pop back up in the new flash. i read in one of the thread that if your battery is dated 3/2011 it will have issues but the 4/2011 or whatever will have less reboot and freezes issues may wanna try getting a replacement if you wanna stick with bionix until krylon does an update.
The andida battery doesn't have a temp sensor, so it's worthless for testing temperatures.
well, idk.. who knows what the crap happened. I charged to 79% and unplugged. 2.5hrs later, I'm still at 72%. That's around 3% an hr. Last night was 17%/hr.. Something happened last night.. Man, I'd love to know what took place.
Either I had an app going wild all night, or the battery really never charged.. and the 100% was deceptive. It's just nuts how all of these probs all of a sudden surfaced right after cwm 4 and putting the stock battery back in. They never surfaced b4 on the same ROM and with the same battery that I used for weeks and weeks.
O'well....

When the battery is less than when it removed,After some time and putting it back will be full power display
SORRY FOR MY BAD ENGLISH
You should wipe battery stats when doing any major rom change (stock to custom or between different roms).
Battery will always be wonky the first time before a full charge/discharge on the rom unless it is 100% and battery stats are wiped.
Typically what I do (on CM7), is when I wake up the phone is at 100%. I download the latest nightly while I'm in the shower. Jump out, it starts to flash. When its done and booted up, I wipe stats then unplug the phone and go to work.
I don't always wipe stats. But with all of the battery tweaks and fixes he's done, I will occasionally.
I very rarely ever completely turn my phone off, but last night I decided to turn it off right before I went to sleep. My battery was down to 25% right before I turned it off. When I woke up this morning the phone would not turn on. So I decided to plug it into the wall charger to see if it would help. Well the phone did turn on after I plugged it in and to my surprise the battery was showing as 0% charged which is why it wouldn't turn on without being plugged in.
So, that means that something drained my battery from 25% to 0% while the phone was completely turned off. What in the world would be running while the phone is turned off that would drain the battery like that?
I have bought this phone 2 months ago, and it is working OK, but I have a problem when charging it:
The screen is switching on and off every 30 or so seconds, and it seems to me, when it gets to 100% full, the phone freezes, since I can unlock the phone when it is not 100 full. The ROM is a stock last 2.3.5 version, and it was the same on the earlier version.
When I come to the phone after some time, the back side above the battery is hot, and the only cure is to remove the battery. If I do not do so, it will drain the battery in a matter of hour or two. Not sure what can causing it.
The other thing is that sometimes I cannot activate BT or Wi-Fi. Icons are flashing but it wont enable it, and after some time, especially with the WiFi it will again drain the battery.
Any thoughts?
P.S, I cannot locate the previous owner of the phone, so the warranty service is not an option
Hey guys, I'm having a problem with my battery. I get a normal amount of time out of it, but the battery indicator is behaving oddly. I can use the phone normally throughout the day and it seems as if it's discharging as it should, but when it reaches 22 - 20% it will stay there for a very long time (about 2-3 hours of screen on time) and suddenly shut off. No shutdown, just off. Won't power on again until I plug it in. Once I plug it in and turn it back on, the battery indicates that it has 1% and seems to charge like normal.
I have never noticed it before I flashed Liquid Smooth 2.8, so I believe it might be a ROM issue.It happens on the stock CM kernel and on KT747. I have already wiped battery stats and upgraded to Liquid Smooth 2.9. I would rather not flash to another ROM as I really like Liquid. It's a very smooth ROM.
Please help me out. Thanks.
