I have had at&t atrix for 2 months or so, i usually take good care from batteries. I charge the phone every night and I calibrate the battery on every rom install.
The calibrating app always reports 4200 and 100% charge.
Well sick of my poor battery life, i left the phone on my room(good signal) with full charge. It only lasted for 35h. It only had google sync on. No gps, no bt, no wifi, no screen ..... I only turned the screen on the last %5 just to check battery stats. most % was from "phone functions"
I am running aura rom with latest faux's kernel undervolted and underclocked(~900mhz).
Should i get a battery replacement? i live in europe so warranty is not an option for me.
Atm i'm going back to stock gb kernel to give it a try, but i don't think it's the problem
EDIT:
Sorry, I have no idea how I came up with 3 days. My mistake.
Leaving it overnight takes about 30% battery, even if I am using night powersave mode

Have you tried the method here:

Also, sometimes you have to let the battery drain completely until it shuts off, then charge it completely before even turning it on, and then calibrate. Even after that you should allow it to go through a couple charge cycles before you get a more accurate reading.

I bought an extended battery on ebay http://www.ebay.ca/itm/EXTENDED-BA...Accessories&hash=item4cf994fb1f#ht_655wt_905 you should do so, with a heavy usage I get normaly 2-3 days of battery life with CM7 beta 2, it's very impressive.

Newbie here - I have a stock G Tablet.
Have added many apps and also Flash and it is working great.
My one concern is that however long I charge the unit,
I can't get the battery indicater to go above 93%.
Is anyone else experiencing this ?
hello there,
yes i am having the same problem. no matter how long, mine can't get past the 95% mark. clockwork mod + tnt 2.2
ideas on how to fix this, anyone?
regards
Try to recharge with the device powered off, and let it charge for at least half an hour after the light turns green.
I've left it plugged in a good 2 to 3 hours after the green light came on.
It still only reaches 93%.
Is it a bad battery, bad charger, etc.,
Any thoughts... anyone ?

Do a full cycle, all the way dead and then charge as stated for about 30 minutes after the green light comes on. It could be just a calibration problem. How long is the battery lasting for you?
I use it for short periods throughout a day, so it is difficult to gauge an accurate time.
A rough guess would be approximately 6+ hours.
I always thought it wasn't good to totally drain this type of battery ?

I think this is a LiPo battery - if so, then its is OK to let it drain all the way - just don't do it too often. You should *always* do two full discharge/recharge cycles on any Lithium-based battery as soon as you purchase it, and again about every month or two.
For removable Lithium-based batteries (i.e. *not* for gtab!), if you aren't going to use the battery for, say, more than a week, the best thing to do is to discharge it to about 50% and then put it in the refrigerator. When you are going to start using it again, let it warm to room temperature for at least a few hours to a day (depending on how big it is), *then* put it on the charger. Absolutely do not charge the battery cold as the thermal shock could damage the battery.
The initial discharge/recharge cycles "primes the pump" so that you get the maximum capacity out of the battery (who knows how long the battery has been 'sitting on the shelf'), and the ongoing discharge/recharge cycles keeps the battery at its maximum capacity *and* allows the calibration electronics more accurately track the slow decline of the battery's capacity.
BTW, my gtab's battery lasted on-and-off for almost 2 1/2 days. That was 'sleeping' it at night (*not* turning it off!) and using it on-and-off wifi/surfing/playing AB during the day. I must say, the gtab's battery life is phenomenal!

Thanks. Tried the full discharge and then full charge with the gtab turned off, left for about an hour after the green indicator, but still stuck at 95%. Even deleted the batterystats.bin file. no change. must i do two cycles of full discharge and charge?
I'm having similar issues. I powered off my gtab overnight and let it charge for 8-9 hours and I have not been able to get the battery to say 100%. I'm going to leave it on all day and let it discharge completely and try again tonight.
Drained battery and left it charging overnight and while I was at work (15+ hours) and its still at 95%. I wonder if I should exchange it now.... I'll give it another week....
If you do two full discharge/recharge cycles and the battery is still not showing 100%, then I would take it back. Either it is the battery or the battery calibration electronics that isn't working (my bet would be the battery). Furthermore, since the battery is "not removable", its just not worth keeping it and taking the chance.
If the battery had been removable, then Viewsonic could have just sent you a new battery instead of having a whole gtab come back....
(Note for Viewsonic - this is where removable batteries are superior to non-removable!)

Before you return it check the actual battery life. If it turns out that it's just a calibration issue and if your happy with everything else, perhaps you should keep it.
Read the thread about my battery test...
mine is different... I can charge up to 100%, and keep using it for few hours at night, put it to sleep, then I wake up in the morning and find the battery completely drained... any1 has the similar issues??

You can try going to settings/applications/running services and turn off all non-essential services before putting it to sleep.
Mine doesn't get above 96%, will have to try the suggestions here but overall I'm still very happy with battery life of the 96%...
thanks, i'll definitely try that... but I don't think I have too much installed or services running since I flashed it with the new ROM.
have you guys notice your battery temperature? i got 2 gtab but both operating at different temperature 1 at 23-24 other is around 31?
My battery life seems pretty good even though it doesn't go higher than 95-96%. I saw in another thread to try resetting battery statistics in clockwork recovery to see if that will fix the battery display problems. I'm going to try that next.
I've got the Malata Zpad (SMB-1002-3G) and mine now wont go over 91% (happened on the 3rd day). It used to charge to 100% no problem for the first two days.
I did a recovery (format) when you press the power and volume up button, but that didn't seem to do anything (other than wipe all my settings and put it back to original factory settings of course)
I'm pretty sure the battery is fine, and lasts just as long, but it would be good to be able to reset the battery status.
PS: My Zpad is not rooted or anything. It's pretty much standard (just running Launcher Pro).

Do you have Clockwork installed by chance? If you do you can charge the battery all the way up and then go into clockwork and reset the battery stats.

Not battery life.
Today i noticed my battery meter has been sticking, any way to fix that? It'll drop 20% upon reboot.
Today i noticed that my battery would spike up from 95% to 100% while charging and not go anywhere in between,. Is that normal? Battery calibration app kept going off early, and then as soon as it hit 100% i unplugged it without calibrating it, and it dropped to 99%. Happened twice in five minutes.
Also, instead of using clockwork recovery, i use Battery Calibration app to wipe my batt stats.
What mV should i be on?
One last thing, how do you bump charge? And is it really that unsafe?

I noticed this yesterday, I had my phone plugged in and it was at 94-95% and 2 minutes later it was at 100%.
To bump charge, once your phone is at 100%, unplug your phone power it down then replug it in. Once it shows the green LED meaning 100% charged boot your phone up and keep it plugged in. Might go back to being orange saying its not 100% yet so let it get to 100%. Unplug it and replug it back in a couple times until every time you plug it in it shows green for 100%.
I would think that it would be bad for the battery if you do this every day, but I can't give a definite answer for that. I use Battery Calibration to do that too, but between today and yesterday after I flashed over the new CDMA/LTE radio leak from the Radio thread my battery life hasn't been great. Considering going back to the stock radio.
I've noticed similar things on my bolt and even my dinc. To counteract this, I stopped looking at the battery % and got battery left instead. This app tells you how much longer your battery will last in hours rather than %. I no longer freak out about my battery life, %, or what others are getting; I've never been happier.

Sounds like a good idea especially for me lol. I noticed this morning that my phone was 56%, down from 74%. 18% drain over the time span of like 6-7 hours or so while I was sleeping. Not sure how good or bad that is, but for me it was just like wow.
You're being anal. Don't worry about it. Your phone is working fine. The battery level will appear to jump around a bit, especially when going on/off charger, or rebooting. Search around if you feel a need to know why.
So I have just flashed the CM7 ICS Themed BETA, wiping everything.
I then charged to 100 percent, and used Battery Calibration app.
I have just setup some apps, and I have lost 10% battery life in 40 minutes
Display is using 85% battery life apparently.
Please help?
It can take up to a week to fully calibrate the battery. Since the battery doesn't have memory the phone has to get a feel for how much juice it actually has. Try it for a few days running the battery down and then charging it to full without unplugging. If that doesn't work you might want to try charging all the way then reflashing and immediately do a calibration.

Yeah, I'd calibrate the battery - wouldn't hurt.
Ideally always flash on a 100 % full battery to avoid problems like yours..

Cheers guys I've taken this all on board.
I'm on 13hrs on battery, its showing 16pc. Battery calibration app shows 3609mv however. This doesn't seem right to me. Am I correct in assuming the phones battery power is the mv listed and no battery is more like 100mv??
Could anyone explain the 'mv' term to me?
Is 0mv when it powers down? Is this indicative of power?
Thanks.
Lithium ion batteries never fully discharge. If they did the battery would not recharge again.
Sent from my MB860 using xda premium
mv referers to mV, as in Milivolt. Most li-ion batteries are rated at 3.7V or 3700mV. A nominal full charge should be around 4.2V or 4200mV.

That's 35 minutes of active use. 10% isn't outside the realm of the possible.
I usually can go a full day on 60% battery, but this morning Facebook, the interwebs and text messaging put me from 100% to 77% in the course of 30 minutes. Draining 10% in 45 minutes does not seem out of the realm of possibility
I get mine to last around 20-26 hrs on a single charge, of course depending on use. but i hardly leave the house and dont use it a whole lot. One thing to make sure of is setting up profiles on SetCPU and/or undervolting. i just posted my setup on another thread. http://forum.xda-developers.com/showpost.php?p=20284361&postcount=28
so after you clicked the battery calibration button and it said calibration successful, you're wondering why the battery is dropping so fast under use right away?
Easy answer my friend, when you first use the battery calibration app, the first cycle (when phone is being used) will always drain a lot faster than the 2nd and 3rd time around.
The battery calibration app, wipes the battery stats, and makes a new one, however that does take at least 1 - 2 times of a full charge/discharge of the battery. There is a battery tread in the atrix general forum i believe for cailbration steps, etc to go about successfully doing a complete calibration when flashing from rom to rom.
Hope this helped
Hmm, maybe I am just upset that I have to charge every night.
Coming from a BlackBerry 9780 I could go 2 days with semi-heavy use.
I am now using the official Motorola cable, and only charging from very low to full.
Thank you for the advice.

Try getting one of these:

1900mah extended battery
Problem Solved.
Bluetooth radio was killing my battery. WiFi is fine leaving it on as it disables in stand by, but bluetooth was absolutely draining everything.
thanks for the update
I agree, 10% loss in 40 minutes of active usage is not bad. If the OP had better battery life before he flashed to new ICS themed CM7 beta rom, maybe the new rom is to blame??? I'd OC/UV, possibly with the latest faux123 kernel.

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.
I have an Atrix 4G running Neutrino 2.9 EE, with a new battery I bought only a few weeks ago because I thought my old battery was dying. But I'm having the same problem with this one. I can't get it to charge past 70% or so, and the charge seems to drain very quickly, about 1% every 15-20 minutes. I checked the battery usage, and Phone Idle is taking up around 60-70%. I've got wifi off, the screen turns off after one minute, and the brightness on half. I'm really at a loss as to what's causing this, so any help would be great.

Try to use all battery till your phone turn off, when charging again go to recovery and clean battery stats, rebbot and charge to full battery, see if your bar go to %100, i install battery widget and have an option for motorola phones, enable that option, that help me a lot,
Good luck!!!:fingers-crossed:

Battery drain issues, it seems, are as varied as "My car is making a noise that goes like this: ____"
Do you have the battery calibration app off the market? A full charge is 4200 mV (or really close to that value), regardless of what percentage your phone is displaying.
If your phone is getting up above 4100 mV, then the battery is fine. You can trick the phone back into displaying a more accurate percentage for a while, but it's not permanent:
- Charge the phone as high as it will go
- Shut the thing off and pull the battery
- Plug in the phone, wait for the question-mark icon to appear
- Re-insert the battery, let it sit for a few minutes (10? 20? no magical number here)
- Turn the phone back on. Percentage should be a lot closer to 100%.
If you're getting a decent charge but the battery is genuinely draining quickly, well... all I can offer is my experience from this summer. My major symptoms were:
- Losing an entire charge in the course of 8-9 hours, but ONLY when wifi/mobile data were turned on
- *Extreme* phone lag when wifi/mobile data turned on. Every single app would force close. Not fun at all.
- Checked what's using the battery, and "Contacts" was responsible for ~5% of the charge.
After six weeks of debugging hell, wiping, reflashing stock, etc I found out my contacts were nonstop-syncing (and duplicating, and duplicating, like rabbit offspring) on one particular email account. Killed the email account, got a functional phone back. Battery life returned to normal. All that to say, one misbehaving app (even a stock misbehaving app) can trash the phone's performance.
If you can stand it, try returning to something completely stock and not restoring any of your apps/data for a few days.
