Does anybody know sone work around regarding this? Because its starting to annoy me, have you ever experienced when you are using your device,the battery warning suddenly pops up and says that you must charge already and the battery percentage suddenly changes to 3% eventhough awhile ago there is still 50% left, but when you reboot it chages back to 50%, what could be a possible culprit, this happens a few times to me a day and im tired of rebooting everytimethe warning pos up.
Any advice is appreaciated
Same experience. I posted this a while ago but no solution.

well this isnt an acutal solution but have you tried actually draining your battery down to 3% recently? By doing that you are "calibrating" the battery life sensor and maybe that will cause this issue to occur less frequently?
This happened to me once so I did that and havent had a problem since. Hopefully it works for you!
but how do you power it on if thinks the battery is critical
Somehow if ido a reboot it just goes back to normal..maybesomething is messing up with the battery sensors,i did let it drain but some how it still the same, i had read on a similar thread about a bump charge or something maybe i could try that and lets see from there
on verizon tab SCH-I800 - does the same thing ... mine seems to happen around 33% though. (i thought it was something with the 33% .. since it would drop down to 3%) ..
i think samsung should really push out an update to address some of the glitches in these tabs..
Tried the recalibration thing. Problem still exists.

thats a similar issue i get,. Yes i tried the recalibration charge also and still having the problem, i did a factory reset also and it did nothing.. Im really desperate for some fixes..
Mine jumps from 15% to 3%. Quite annoying, I assumed that it is because it is poorly calibrated and so it doesn't realise its actually critical until its 15%.
I tried calibrating it by running it until it switches off, and then fully charging. However, that didn't work.
If in reality the battery is at 15%, then its a pretty bad software bug.
Maybe deleting the battery stats solves the problem?
I think its getting worse on mine now after a full charge after i remoce the charge around 2min. It says 3% again what the heck?

try to flash it with rotohammer rom JHA/JMC it might fix the issue. My problem with GT was battery draining too quickly but after flashing it's much better now.

This worked for me too, however I had to do it 2 or 3 times. I haven't had any problems since.
I think i sorted it out also by calibrating battery,i removed the battery stats using the root explorer,now im still observing the progress
Brand new sprint tab, only installed the over clock kernel first week i got the.
Today, which would be week 3, i experienced the 35% to 3% drop instantaneousness..... So, im draining the battery, and hopefully doing a full recharge...

I also have a sprint tab and it is three months old. I have not put another rom on it, only rooted it. It also has developed this battery problem recently. It will go from 53 to 3 all of the sudden.

Not too sure what's the issue but it does sound like a program consuming too much CPU or the battery calibration issue.

Hello,
Anybody on this board actually never did modify their phone and received OTA update from Motorolla? I mean never rooted/unlocked/ etc original Atrix and went through official channels to update it? Can you report if you see "battery jumping" issues (battery available is higher after reboot then before reboot)?
I know it happens on all Gingerbread releases for me but I don't know is it becouse I was tinckering with a phone or something to do with my phone in general.
So I was wondering if 95% of people who does not even read this board and abide by ATT rules after getting latest Gingerbread update actually left with this awfull bug?
My phone has never been modified (meaning no root, unlocking, PROMs, etc) and it does have the battery bug.

So you got OTA update and on Ginberbread now, right?
You sure you don't have this bug? Please get down to something like 50% battery avaialble and then reboot your phone and see if it's changes.

Stock, unrooted, locked BL and OTA to gingerbread
I'm now rooted mind you but in the last 24 hours I've not observed the bug (yet) fingers crossed. Battery life seems identical to before (basically around 10% an hour with 30 minutes bluetooth music and 15 minutes surfing, 3-5% an hour if idle). I do leave everything on and run skype + trillian in background (I didn't buy horsepower to leave it idling lol).
What about FP scanner? How is that working for you guys?

Did you reboot the phone to check if you have this is issue or not? Let it drain 30% of battery and then reboot and check if battery meter jumps. Several people on another thread reported that they don't have an issue but after actually rebooting and checking stats actually confirmed that issue is there.
I ran my battery down until it shut off and charging it has been a pain. Once I put it in the standard charging dock it powered right back up and said it had 50% battery left. Turned it off and back on again and it said 20%, repeated that and it went down to 5% then powered off by itself. Left it charging untouched for 3hrs and the battery only made it up to 20%. Really odd.
I ran it down until it powered off again and its been on the charger ever since. I would guess another update will come out to correct this battery bug in a week or two.

Had to delete my fingerprint profile and recalibrate/setup my fingerprint and now it works pretty much like it did before.
edit: got it! wohoo, sort of
Just tried this and I can't recreate the battery bug:
battery at 70%, restarted phone 3x, battery still at 70% each time
played a game for a while, battery went to 50%
restarted phone 3x, battery still at 50% each time.
used phone some more, phone still at 50%
restarted phone, still 50%...no jumps in battery graph
restarted phone, 100%, battery stat restarted completely (time was only 1 min 6 sec vs 8hrs before the restart)
restarted phone, back to 50% (time on battery did not reset, at 2m 19s)
restarted phone 3x...still at 50%, no time on battery reset
phone setup, fairly stock:
flashed .83 SBF (had the swype beta installed with no stock swype backup), applied the official 2.3.4 through SD card, rooted, swype beta. stock launcher, no battery/task/data monitoring type apps. motoblur account is set up and running.
Maybe a factory rest will straighten the phone out?
I'm rooted, bl locked, and updated to gingerbread using the official OTA.
I saw the bug initially when I had updated my phone while it was around 55% battery level. Immediately after the update, the battery level was at 70%. However, after rebooting my phone again, the battery level returned to normal and registered at 53%. Since then, I haven't seen any battery jumping issues - even after rebooting (it decreases probably 1% after the reboot). *shrugs* Maybe I'll see the battery bug issue if i reboot at a lower battery % level.
In terms of performance of the battery, the overall drain has been about the same as when it was when it was froyo. 1-2% per hour at idle. I usually get somewhere between 4 and 5hrs of display time and it's been the same for gingerbread thus far.

It does not seem widespread (using xda as a sample size is way too small and skewed). And it does not seem to happen all the time/seems to occur at random and only on reboot. Yes it's a bug, but it's not huge IMO. If you have it just apply the battery fix in the dev section.
for those that see the battery jump, does the time on battery stat reset?
Me too had the same battery jumping issue. Battery life indicated was highly unreliable and inaccurate. I discharged the battery down to the point it shutdown. After putting back to the charger it showed the battery to be at 50%. I let it charge again. Battery indicator seems to be reasonable now.

I don't really understand the point of this thread but you can simply flash this in CWM to fix any battery issues in GB: http://forum.xda-developers.com/showthread.php?t=1174349&highlight=Fix
i never modded/rooted my atrix
had 40%, received OTA, it read 73% restarted, still says 73%
It's piss poor for a company like Motorola to release a ROM with a bug like this.
My phone is stock and i also have this issue.

The reason i want to know is simply to find out if the official OTA fixed this bug and if it did that means the leaked beta from kennethpen is outdated since AT&T fixed it and may have also fixed other things (perf, batt efficiency etc.)
guys chill out lets all run the battery through a few full cycles before jumping up and down
you never had weird battery readings after flashing CM6 or whateaver?
for the record yes I"m affected, stock locked unrooted to OTA2.3....
currently, my Atrix always could not charge battery fully even using electric outlet. is there anybody know how to fix it.
You could try calibrating it.
Charge the phone until it no longer charges. Leaving it plugged in, shut the phone off, then pull the battery. Wait for it to boot up and display a ? and battery symbol. Then place the battery back in. It should read 5%. Leave it for a few seconds, then boot the phone. Should now read 100%.
definitely trying that later today, thanks.

This, but I would add, that when you reboot, go to recovery first and wipe battery stats.
Mine has the same problem. Never charges past 60%. Calibrating, wiping battery stats several times does not fix it. I plan to buy a new battery to see if that solves it but I am not optimistic. Search for the thread named "atrix not charging past 88%", no fix for me yet and several others.
re install rom and full wipe
Don't forget to flash the juggernaut battery fix too

Same issue here, the percentage isn't always the same though. One morning it will be 94, 96 the next, and 90 the next. Always at 4207mv at those points. Tried wiping batterystats full, empty, etc.

I thought this was already part of most roms out now?
Juggernauts fix helps the battery jumping issue, but not the battery not charging to 100%, at least not for me. The problem started after flashing official 4.5.91 and it has continued after I flashed to CM7. I am now used to removing the battery and putting it back in place while charging for it to read 100%, but it is annoying no one has found a cause or solution.
It really works

Hello!
Sorry I can't post this in the Paranoid Android thread yet. As a noob I can't post in that forum until I have 10 posts so I'm at a loss as to where I should post this.
Anyway, I just put the new 2.1799 PA ROM on my Nexus 7. Unfortunately, I seem to have a serious battery drain when the screen is on. I have read many posts where people claim to have easily achieved 6+ hours of active screen time per battery charge whereas I'm only getting 3-4 hours of active screen time per charge, almost all of it related to web surfing. I have a strong wifi signal and I keep my screen brightness around 20/30 range. I'm not sure if it's the ROM or if my battery is defective.
I have also read about a battery calibration app through a different thread. Is that necessary for the PA ROM? I didn't see anything in the tutorial mentioning a battery calibration.
Included are two pictures, although they aren't very indicative of my problem as my tablet was sitting in my backpack for most the day.
Please tell me I'm just being paranoid! Thank you for the help!

The battery recalibration is a myth, but there is also no harm in trying it.
according to the pics you have attached, there doesn't seem to be anything wrong.
Battery also drains faster if you have too many apps that have services running.
Ex: Facebook.
I know there is a battery warranty, but how bad does it have to be to get it replaced? My battery cannot reach the 9.5hrs of 720p video playback (with headphones in) as achieved by Asus. I can only get 8hrs. From normal usage, I am only able to get 6 hours.
The ROM has less to do with the battery than the kernel does.
I would say try flashing another kernel. The default cyanogenmod kernel that comes with Paranoid Android didn't give me very good battery life.
Franco kernel gives me excellent battery life. Other good ones for battery are Faux or Motley.

That is in the normal range i would say, Companies usually exaggerate.
As suggested try franco's kernel.
He has a free kernel flashing app on the play store.
My issue is with how the battery percentage is running down......
Charge the N7 to max and use it for a good 2 hours and the battery STILL reads 100%.
Even if I then shut down and reboot it still shows 100%, then all of a sudden it will start to drop very slowly at first until it gets to around 40% which it then shuts down and will not reboot, obviously void of any battery cells.
Clearly it's a calibration issue.
This is on a stock non-rooted machine.

I tried his kernal. I did my video play back test and I got the same 8 hours as before. During normal usage I think I will get about 30-40 more minutes. Still not what others are getting

Try a factory reset. If that doesn't work, you're more than likely actually looking at it being a hardware issue.

Factory reset was the very first thing I tried when it started playing up.... I'm hoping when 4.1.2 rolls out it may clear it. If not then I'll have to look at doing a root and access the battery file to see if deleting may help.
Thing is a recharge should clear out the battery file stats and calibrate, which clearly it's not.
Apart from this the N7 is flawless so it's staying with me. Running hours is the same, just doesn't give an accurate reading of how the battery is running down.
It's not a big issue.... to be honest I'm more curious than annoyed.

Have you tried installing a 3rd party battery app to see if it registers the correct battery output? This is the one I have used, works good. GL

You do realize that wiping batterystats.bin has absolutely nothing to do with the battery fuel gauge, right? It does not "calibrate" the battery or affect reported charge. The myth of wiping battery stats has long since been debunked by Google's Android engineers. The only info contained in the file is a list of apps that used battery since the last full charge.
The only other thing you could do besides a factory reset is see if 4.1.2 fixes it for you. If not, then it's definitely hardware causing the issue- the battery charge is likely being improperly read and reported by the battery itself.

I've just flashed PA latest build (dirty) and my battery stats are pretty messed up, apparently Bluetooth was the biggest drain on my phone, 57%, and it was on for nearly 50 days.
I don't use Bluetooth and obviously a battery lasting 50 days is nonsense.
I've had a search and found people experiencing high drain from some services, or reporting 100% charge as soon as plugged in, but can't find anything resembling my problem.
Is there a way of resetting these stats without having to do a full wipe. I tried charging to 100% but they remain.
get battery calibration app, should delete the stats shouldnt it?

Thanks for replies. I did a charge last night but the stats remain. I probably didn't charge to 100% just almost 100%.
I find that it can take up to 30 minutes to go from 99% to 100%. I will leave it charging overnight and hopefully that will sort it
That Bluetooth figure just seems weird, and I have no idea where it came from??

Anyways running Franco kernel and PA on this and get 5.5 hrs of sot with YouTube and music playing all the time xda browsing Facebook and mostly on WiFi but on 3g when WiFi signal is lost when I go outside. Auto brightness on and screen does take up juice outside but I believe I could get 7 or 6 hrs if I played with settings, underclocked, minimum brightness etc...
