Just took the update and battery life dropped significantly. I was running stock rom, rooted, and kernel with CWM. I could use the phone quite a lot and it would last all day and still have 25%-30% left after being off the charger for 17 hours. I flashed the stock kernel and performed the update yesterday. I charged the phone all night. I was off work today so I didn't use the phone at all. After 15.5 hours, the low battery notification sounded. The battery meter showed I only had 11% remaining. The main culprit was the "Android OS" at 77%. Display, which is normally the main power drain, was only 6%. This shows how little the phone was used.
I believe its Entropy who has a thread that has really helped me. Could be a rouge app. Do you have better battery stats?

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.
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.
So I was one of those who was finding my battery life to not be sufficient on the Photon and bought the Seidio extended battery. First thought is that it does make the phone heavier, but I can deal with that. Not a deal breaker.
My issue is that the Photon doesn't recognize the fact that I now have the extended battery. I've spent the last two days using Battery calibration software (charging overnight to 100%) and then trying to discharge completely and recharge. The problem is that the phone continually is showing 1% for almost 3-4 hours if not longer. I can't get it to recognize that there is more juice in there.
While it's great that it seems to be working well (first real work day with it today), having the battery drain like mad (or seemingly) and then sitting at 1% for half or more of the day and not knowing when it will die is a problem.
I wonder if this is why the stock seemed to drain so quickly - maybe it's a programming bug? Firmware bug? I dunno. In any event, any suggestions on how to make the phone actually see that there's more juice would be great.
As an FYI I've used "Battery Calibrator" - both of them and Battery Drainer and Fast Discharge to get the phone down. I am rooted, but everything is stock other then the root itself.
Thanks!
Rumor has it, that the latest software update decreases battery life. I have the latest update, (I understand that many have this issue updating, if you do, look it up in the forums, you will need to SBF the first version of software to your phone...), and my battery life could be a lot better, like it used to be.

Well the issue now with the new battery isn't so much battery life. With the extended battery the life is stellar. This issue is that yesterday at about 3 in the afternoon the phone showed 1 percent battery life. Yet it didn't ever die. When i plugged it in last night before going to bed, at 1200, I still had 1 percent. So the issue is that the phone isn't properly recognizing the battery life itself.
Help?

I understand that you have used the battery calibration application, try installing CWM, ClockworkMod, after you root the phone. Drain the battery, charge to 100% boot up into CWM, and go to advanced, and clear battery stats...
If that doesn't work, then I could be the battery, or the phone itself. See if any other members have any insight.
Can't change bootloader on photon without breaking 4g as far as I know. Will crosspost in main photon forum. Thanks!

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.)
Hey guys,
I have had my Galaxy S2 for over a year now. I have not always had great battery life but I blame that on my providers ****ty 3G connection.
My longest battery life I had on Hydra h2o ICS rom and that was about 2 days with 2.5h screen time. Those were the good old days.
Now I'm on Vanilla RB with the DorimanX kernel and am getting a little concerned if my battery could be failing me.
I have tried for some time now to get stable, good battery life on the JB ROMs and it doesn't seem to be working. This is my case:
I charge my phone at night and use it over the day. The past weeks my phone has really been heating up and the battery is draining to near-zero levels within 2 hours of screentime. For instance I was playing a game the other day for about an hour on and off and lost 70% of my battery. The thing is that when the battery drains this quickly it always seems to slowly increase as the day goes by and if this happens, the phone can hang for an hour or two on the last 2%.
This I find really strange and have tried numerous times recalibrating the battery and doing cycles and everything I have thought of. I don't have any strange wakelocks that can explain this drainage.
For instance my phone completely died on me this morning after rebooting it at 50% and it booted up with 1% left. I then took the battery out and waited a couple of minutes. In the process I checked the battery out and it smelled strange. I also thought i noticed a slight bulge on one of the flat sides of it. When I popped it back in and booted my phone it was at 13% and slowly increased to 22% before starting to discharge again.
What I'm wondering is if my battery is broken and I should buy a new one of eBay?
edit: Right now I was charging it and rebooted. It went from 22% to 63%. Isn't this just a bit strange?
If you detect a slight bugle one side of the battery.
It means it is time to change the battery before it burst.
The battery is not hold a proper charge or discharge it properly, itr could be one of the filaments maybe damaged in the bulging area.
Okay, is there any aftermarket battery that is better than the stock Samsung one?
I also have the same problem after flashing on stock ROM. Solved with app "battery repair". Honestly it was not original (replacement) battery, but it still works well.

Yes, multiple calibration attempts.
But it's the bulge on the battery that has me concerned. It´s even ath the point where my back cover can't hold back anymore and sometimes comes loose where the battery is bulging.
One thing I'm noticing is that in AnTuTu Tester it shows the battery at higher voltages than the 3.7V on the back of the battery. So far I've noticed this go as high as 4.2V.
Is this something that is not ok? If not, could it be my phone or my battery's fault.
edit: 3.2V now during testing...
edit2: went all the way down to 2.7V during the testing (about an hour passed) and I experienced heavy screen flickering at around 22% left of battery and then the phone just shut down. Battery temp was at 39° right before shutdown.
Just recieved a new 1650 mAh battery today in the mail. Gonna give it a few cycles and post the results here.

It's works for me, but not a panacea for all problems.
