Different battery discharge rate. Any ideas? - Galaxy S II Q&A, Help & Troubleshooting

Hi guys. I'm running on CheckROM revoHD4 and while sometimes I lose 10% of battery overnight today I dropped 30% in 3.5 hours doing absolutely nothing with screen off and not a huge ammount of apps running on the background. And its not the first time I notice inconsistent discharge. When I installed this ROM battery would last for 20h/3h screen/3h voicecalls. now sometimed it doesn't even last half of that. Any ideas?

You should check the battery info via Settings > About Phone > Battery Stats to see if you find a proccess that is huging the battery.
Also you could download Better Battery Stats from the Market and find which proccess are the ones doing the more Wake Locks and how much time they have done it. You could find for example an app thats been doing that for hours and that could be the cause of the battery drain.

Battery going down like mad

I been using using the the Elelinux gingerbread rom and have not have the greatest battery life I turned off wifi Bluetooth and my internet connection on my phone and in a hour I lost 15% I did not to anything in that hour does anyone know how I can increase the battery but I never lost 15% in an before like that I normally lost 0% but today when I fully charged it this happened does anyone know his to increase the battery life
Go to:
Settings -> About Phone -> Battery Use and check what is draining your battery.
You may also use consider lower Min CPU frequency. I'm running on 19 MHz.
i did nothing it that hour with my phone all i did with my phone an placed it on a table and watched tv
You might did nothing but some widget could drain battery like hell Check battery usage as per my first post. I'm using Elelinux-7.0.0-RC0-Hero-v0.7 and my battery life is very good, with all stuff "on" except BT.
but after i while the battery life a bit better
Have you tried to reboot? I just realized that after first reboot after I flashed new rom Android Service process was draining my battery like hell (3 times more than Display), my phone was down within 3h. But after I rebooted everything was ok.

Froyo OTA and battery issues

My brother did the OTA update last night, his phone has never been rooted.
After about 5 hours today his battery has about 20% life left! Battery stats says 74% of the power was used by the display which was on for 40 minutes.
Cell standby is about 4% of battery use and he was without signal for 25% of the time, if I recall correctly.
Anyone else observing something similar?
My battery life on 2.9.2 has been less than desirable and I was considering going back to stock in hopes the battery would be better after the OTA. This is not encouraging.
Also, does he need to go through a couple battery cycles, drain fully then fully charge, before he gets a clear picture of what the battery life would be?
TIA
Yes true battery life will be clearer after a few days of use. The phone learns your usage and gives a better idea of how much charge is left.
best way is to fully charge battery and then wipe battery stats and then drain battery and then charge battery to full one charge. Then use phone normally for s couple of days. Then you will hadn't good sense of what kind of battery life you are getting.

Thanks for the response.
Am I correct that he would need to root to be able to run the battery stats script or is there another way?

I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...
I agree, the OTA froyo ED01 is worse for battery life. I get 5-8% per hour idle drain, which is way too high. I've been try to track down the issue with spare parts, system pannel, and battery details. So far I can't see any specific issue.
There are so many hoops to jump through just to get this phone working normally. It's really insanity that we should have to bust our butts on software bugs. And this isn't even mentioning the totally slow choppy ass browser in 2.2. (Vibrant browser on 2.2 SO much better)
Overall my urge to flush this POS down the toilet is growing every day.

Help with my battery?

My battery has horrible life. I'm rooted running evil fascination and have done all the things that typically help with battery life such as disabling gps and wifi, and lowering brightness. In fact my brightness is currently as low as it gets and my battery use shows my display as 99% of my current usage. Even though I just took my phone off the charger 15 minutes ago and it's already at 85%. I know my screen can't possibly have taken that much battery so fast. It also takes about 4 hours to charge from zero to 100 because it's draining so fast. Can anyone give me some advice? I downloaded an app that shows my current mah or whatever but I don't know what that means. I notice when it's at 270mah my battery drains fast which is most of the time but a few times it has been at 2 mah and it doesn't drain fast then.
sounds like a rogue app keeping your phone/screen running when off.. I had the same problem a while ago, 96% screen usage and taking 6 hours to charge then draining to zero in an hour and a half.. unfortunately the only thing that fixed it for me was a complete data/cache wipe and reflash of the rom, I think I was on superclean 2.9.2 at the time.. could be the battery being wonky also, you might wanna look into the battery calibration app on the market or wiping batt stats in CWR

Terrible battery life with the OTA update

I have the stock 4.5.9 gingerbread update on my AT&T ATRIX. However I am observing a terrible battery life. There are too many solutions in the forum to follow. Can someone direct me to the appropriate one? I am rooted and unlocked. I used the unlocked 4.5.9 sbf for upgrading from from Froyo to gingerbread 2.3.4

there;s a lot of solutions because poor battery life can be cause by many things, you have to find out what is draining your battery. try calibrating first let it drain until your phone turns off and then if you have cwm install then wipe batterystats and then a full uninterrupted charge
Try setting profiles in SetCPU and freezing apps with TitaniumBackup. Theres a topic for each of these two solutions.
battery stats 6h 3m 29s on battery (now left with 10% of battery)
Display 49%
Phone Idle 22%
Cell standby 6%
Android system 5%
Launcherpro 3%
xda 3%
Android OS 3%
this is just terrible .. i never had such battery life with Froyo. i dont understand what might be the problem. Meanwhile i will try to calibrate my battery.

Calibrate your battery.
Then freeze your bloat.
Problem solved.
dont forget you might also being playing with your phone a lot more trying to see all the new stuff in the update. Thus causing more battery drain.

There are some strange things happening with the battery. I let my battery discharge completely to the point where phone shuts down. Then I plugged in to charger, waited for 2-3 minutes so that I can start the phone. Started the phone and saw 50% battery. Don't know what's going on.
I was told by an admin from another site that most of the battery programs do not work with ova ginbread. You go to settings/about/status and observe the battery. I do no I was also getting flaky results with 2 of the battery programs.

That's a GB bug... there's a battery fix in the development section to flash which deals with the reboot battery jumping. (turn off phone at 50%, turn on phone and it says 70%)
I am having problems with my Atrix too. With my usage, I used to be able to get almost 3 days of battery life. Now it hardly lasts a day. I have checked pretty much all settings (sync, sleep) and all seems fine as far as I'm concerned. So I am having hard time trying to find what is causing this. The only suspect I have right now is wifi. I don't think wifi is sleeping even though I've selected "When screen turns off" in the sleep policy.

Battery Drain <== Core Apps

Hmm...well, this is the second time that this has happened in the 2.5 weeks that I've owned this phone. I'm currently running unNamed ROM 1.2.0 and noticed that my battery is draining quicker than usual (8%-10% drain per hour on IDLE).
Usually, my battery drain is between 1% - 2% per hour on unNamed. What I've noticed in both the instances where my battery drains rapidly is that I end up seeing 'Core Apps' (white envelope with android icon in the middle) under the Battery Usage. From what I can recall about this icon, it's the icon for the launcher. CPUSpy shows my phone at 78% deep sleep (the phone's usually around 93% - 95% deep sleep when in idle).
The first time this happened, I was away from home on business for 1 night and ended up having to power my phone off when it got down to 11%. Got home later that day and recharged my battery while the phone was off and after the phone was 100% charged, it lasted 38 hours with 7% left before I powered off and recharged. Again, the battery with light usage lasted 30 hours with 30% left.
Today, after charging (while off - seems to charge better this way) I was surprised to see that my battery was draining at ~10% per hour and I saw that 'Core Apps' was listed under Battery Usage again.
Fortunately, I am not away on business this time (yeah, my spare charger is on the way) so I can recharge teh phone at home. Is the only way to "reset" the phone's battery usage history by pulling the battery or charging the phone?
Hopefully, one of the devs can answer or provide a fix/workaround for the 'Core Apps' drain? (BTW, I leave my WiFi on all the time and my phone still lasts anywhere between 28 hours to 40 hours...just wondering why I have these sporadic glitches when the battery doesn't seem to last long.)
From my experience... this will be very hard to fix. Usually appear ramdomly, and disappear randomly.

Yeah...the 1st time it happened, I was wondering "WTF is 'Core Apps'?"
Now that I've seen this the 2nd time, I'm stumped by it since you're right...it doesn't happen often and doesn't seem to be reproducible by any consistent method.
Hard to do a battery pull with this Neo Hybrid case (case is a PITA to remove) and I don't have my 2ndary charger yet...
Rebooting the phone does nothing since the battery history remains and even powering off for an hour and then powering the phone back on still doesn't clear out the battery history so the drain continues!
Oh well...it is what it is then I guess...I was hoping that someone smarter than I could find a way to cure this. (BetterBatteryStats doesn't show this as a wakelock (partial or full)...CPUSpy just that my deep sleep state is in the mid to upper 70% which isn't the norm.
Oh well, hopefully, this doesn't happen too often.
Wiping battery stats in CWM does reset the battery useage screen.

But a few have reported their phone doesn't behave right in reporting battery percentages after wiping battery stats.
Doesn't mean you can't. But no one has proven it helps.

I haven't had any issues that can't be directly linked to something else (like random reboots).
If all you want to do is reset your battery useage screen to zero it definitely does that. The point isn't to help anything, just to reset the screen to zero without having to wait for the phone to charge all the way.
In that case not a bad idea if you see it show up. If it's as bad of a battery drainer as it seems and still running, it should show up again pretty quick after you clear battery stats.
It'd be useful in reading the logs to know that at a certain time it was for sure running.

Dunno, it's just odd...recharged my phone last night and now I'm back to 1%-2% battery drain on idle and the phone's going back into deep sleep at 93% and I haven't touched any of my settings. I just let the phone dip to 19% and powered off and put it on the charger for ~4 hours (I know, I could've pulled it sooner since it wasn't at 0% but honestly, I forgot.)
It's just the weirdest thing...whenever Core Apps appears as the envelope w/Android icon it seems to be persistent and stays in the battery usage. However, there have been times when the Core Apps appears as teh same icon as 'Contacts' and will disappear on it's own after a while. <-- This seems to be okay as the battery drain remains minimal.
I'll have to check out Entropy's battery drain thread later to see if I can gain any insights. (Haven't ever flashed any of Entropy's kernels as standalones -- I've just been flashing unNamed ROM so I know the kernels are stable builds and not the experimentals.)
