when i check *#*#7378423#*#* --> service tets --> battery test
WTH ....1500mAh not 1750mAh....why????
mine 1697,5 mAh
mine also says 1500 wth?
Could this be something that the new update fixes? That some phones report having less than 1750 mAh.
The same thing happened to the Lumia 800.
Ok as your battery discharges your figures will lower to fix it press and hold volume up + Power until the phone vibrates 3 times this resets the counter back 175000 and then charge. I done this on mine, I think this like a calibration method.
i gave it a try...its still shows 1500 on my xs
for me too,still 1500!
56% left and mine says 1750 mAh
Running fw. 67
Sent from my LT26i using xda premium
me to, it show 1500
That's very strange. it is definitely 1750 mah battery in the device. I just did it this morning. Did you guys wait for the 3 vibrates when you held the keys down?
yes, and after restart, my phone was in flight mode...

Flight mode???? OK something definitely don't look right. It's just a reset.
Try battery health test instead of battery test, it gives current capacity in uah. (mine shows 1725000)
I have noticed that during charging the led will go from red to green at 90%
Out of interest what battery tech does it state ?
Under battery test it shows mine as 1500mah and tech li-poly

Yep my one also shows Actual Batt(uAh): 1750000 under battery health test but it shows 1500 mAh under battery test. I've already tried the reset and it's same.
Another one showing only 1500mah here...
The reset has worked if under health test it is showing the max capacity

Mine worked too! Before reset it was 1697 and now it shows 1750
I've had a strange one in the beginning it showed 1750000uAh and after a while I checked again and it said 1685000uAh, so I did the reset and now it's showing 1750000uAh again
Any one actually run the battery test? I am running the test but took so long and haven't complete yet???

Hi guys, I am at my wits end with this stupid phone, If its not one problem its another. I was convinced this phone would have amazing battery life once seeing my cousins AT&T version, I bought the UK T-mobile version and its been plagued with faults. The main fault it has developed now is that it won't charge past 96%, I have configured the battery and installed the 1% battery fix and nothing is happening also my battery has been draining quicker than usual. Sometimes I get 13hrs sometimes I get 7hrs!? Could someone give me some advise? I was thinking of ringing my insurance company for a replacement (as it is with my bank and usually they just replace the phone)

I'm sorry, are you sitting in front of my phone? I have followed this correctly on another atrix and it has worked for them, I don't know why its not working on mine I have followed it through properly.
How long have you had the phone?
One thing we all have to consider is that since the dev community has had to provide "fixes" for the Battery Reading on the Atrix it might be safe to say that at some point the measurement might become too accurate. What I mean by this is, I've had my phone for almost a year now and I'm pretty convinced that the reason my battery won't charge past 97% is because of the natural degradation of the lithium battery. It is a fact that lithium batteries can lose up to 10% of its charge capacity after a year. So I've accepted the fact that my battery just might be losing capacity and the battery mods I have applied to my phone are just that much more accurate.
This reminds me of the recently released Galaxy Nexus and people complaining about the signal and Verizon responded with that the "reading" was too accurate and that they'll release a patch that will basically "lie" to the end user about the strength of their connection.
http://www.androidcentral.com/verizon-galaxy-nexus-signal-strength-its-not-us-its-you
Verizon is just basically saying "Here, let us cripple your phone for you"

I have had the phone for about 3 months now. This is why I am saying its weird. The fact that it dies so quickly is another thing I got about 7 hours of moderate use with about 1hr 45 display time with 10 mins of music and about 10 texts and a few phone calls(about 3 short 5 min ones)l
All of you are talking percent. What is the power level of the battery at max charge? Battery showing charging to 100%, or any other percent, and having full charge are not the same thing.

Could be a faulty battery. If you've only had it 3 months I would try to get the battery replaced if it has drain issues.

You make a good point, I use Battery Monitor Widget Pro and keep an eye on usage time rather than battery level.

The battery never reaches 100 on the phone it will sit there at 96% and even the battery calibration app says the battery isnt at 4200mv (which apparently it should be) its at 4190. I never charge mid way I always let the phone get to about 15% then chuck it on charge.

Well I use the internal android one but I want to know whats draining it because today nothing was running, i had everything shut down and frozen that wasn't necessary.
You might need to use a 3rd party app to find the "rogue" app/process. Other than BMW, I also use System Panel to monitor it if I notice my usage time is depleting, it works well. You have to have monitoring activated and it's only available on the paid version, but you can use the free version to manually watch your apps/processes.

Ok so I recalibrated the battery and got rid of the 96% freeze but now the drain is quicker than ever :S
have you tried wiping battery stats as well? Also, when you recalibrate, do you go through a couple "full" charge cycles? As in, do you allow the phone to fully discharge and then completely charge it plus at least an extra hour? I know that lithium batteries do not have the "memory effect" but I think it has more to do with software rather than the battery itself.

yeah i do wipe battery stats but the mAh is not going to 4200 its stuck at 4186 nd wont go past 98%
Something else you could try that I've read around here.
1. Charge the battery for like 4 hours until it won't charge anymore.
2. Unplug the phone from the charger, turn it off, and then pull the battery out
3. Plug the phone back into the charger (Do not put the battery back in yet)
4. Wait for the phone to show an image of a battery with a question mark in it.
5. Put the battery back in.
6. Wait for it to recognize the battery, it will probably give a very low percentage like 5% or 10%.
7. Do not turn it on yet, let it charge for another hour or so.
8. Once you return, it will still probably show a low battery reading, ignore that and boot into recovery while it's still plugged in by long-pressing the power button and when you see the green led notification light press and hold volume down
9. Wipe battery stats and then reboot.
10. Wait for it to boot and then unplug it from the charger and check the battery reading.
I really don't understand what this does but I've read it has fixed the issue for some people.

I'm having this problem with my i777.
Sometimes when I reboot the phone the battery charge drops enormously, like 30% or so. For example, I will be doing things with the phone, the charge will be at something like 60% then reboot and right after reboot it says charge is 30% which doesn't make much sense.
this happens with the stock battery but the effects seems to be more pronouced with some batteries I bought on ebay.
Anyone has any idea what's going on?
what rom are you running on?

Normal behavior of our fuel gauge hardware - high load (boot process) immediately after a reset confuses it and makes it report low. Effect is much more pronounced at lower states of charge.

That's exactly right. Tends to happen more on lower states of charge.
Does this mean that the charge indicator will go up after the reboot? Or maybe it will take longer to drop and the effective battery life will be the same.
Yes when this happens to me my bettery either dies extremely slow or my percent just goes up..

I see this too. I will be at ~40%, reboot and see 10%. Come back after a while to 12%, and it stays on 12% with like an hours worth of heavy use before going lower. If I look at the battery usage, it trends down, then drops, but stays level, then about when the trend would have been it starts dropping again.
I thought I just needed to calibrate the battery, as I just flashed a new ROM. But, it keeps doing this after a week, and several charge cycles.
Guess I'm relieved to see this weird behavior is not indicative of a problem.

Correct - because the gauge thinks the battery is lower than it actually is when this happens.
Attached a screenshot of the battery use with the big drop in effect.
I particularly think this is a bug and Samsung should fix this behavior.
It can't be changed without hardware alterations.
As with anything in engineering, there are tradeoffs. The positive aspect of this fuel gauge design is that it does not require ANY calibration. No wiping battery stats, no "always flash firmware at 100%" - none of that.
The negative is that in a few corner cases, it gets thrown off temporarily. This is basically the only known one.
Ive noticed this as well with both Stock and ICScreweD. I just try to reboot as least as possible.

If you reboot at higher states of charge, OR reboot when on external power, you should not see this issue.
I just had this same problem lol. I was at 42% and when I rebooted my phone it dropped to 23%....This was a few hours after the OTA update to 2.3.6.
I had the same problem also.
-Battery would not charge to 100% ( it would charge between 97% -98%)
-Battery would drop 20% or 30% percent (when reboot).
I tried to recharge many times and cycles the battey but nothing would work.
I tried changing kernal, modem and roms . Nothing would work.
I actually thought i messed my phone up.
So i tried something that work for me.
1) i would let the battery drain till it was completely dead!
2) I would take battery out for 5 minutes.
3) put battery in and charge with phone OFF till it reaches 100%.
4) unplug charger from phone and take battery out and wait 5 minutes.
5) put battery back in and plug charger up and wait till phone marks 100% again ( This time the wait was longer to get to 100%).
6) i repeated step 5 untill finally the phone would mark 100% faster
7) unplug phone and then wait to see the battery status ( if your phone mark 99%) plug charger to phone and let it charge till it reaches 100% again. once it reach 100% reboot and repeat step 7 untill you reboot and it would show 100%.
not sure if this might work for anyone else but it did work for me. battery would charge to 100% and i don't have my phone drop 20-30 percent after reboot.
If it drops 20-30% on a reboot when the battery is near full, you may have a defective battery.
I've only seen major drops on reboot when the battery is low to begin with, never when at higher states of charge.
Doing a full discharge on Li-ion batteries puts a huge stress on it and greatly decreases the life of the battery. To get the longest life out of a battery, you want to generally stay in the medium range of charge (Don't over charge it, and don't discharge it too much). Cars like the Chevy Volt employ these techniques to encourage a longer battery life, however with phones, you get users that think discharging the battery all the way solves problems. If you want to see the true battery life that the fuel gauge averages from, press *#0228# in your dialer and check the battery voltage. Full is around 4.1v and discharged I believe is around 3.5v or so. (maybe 3.3? not sure)
3) put battery in and charge with phone OFF till it reaches 100%. <-- is probably what fixed it, and why I switch batteries instead of charging on my phone because the charger is able to control the current and voltage better than with a slight load on it (with phone on)
I'm sure that that user cut off at least 5% of his overall battery life with overcharging it like that though...
Same issues here pending the ROM I'm using.
4.2 volts is the upper limit for li-ion - and actually, it hits that at around 95% charge.
The method for charging Li-Ion:
Charge with a current limit initially - on our devices this is 650 mA.
Once you hit 4.2 volts, do NOT go above this - maintain voltage at 4.2 volts or lower regardless of current
Once current drops to around C/10 (on our devices, this is about 160 mA), shut off charging completely.
The phone's charge controller does this all automatically for you.
There's usually a timer/averaging filters in the final stages of charge termination - which is why "bump charging" can push a little extra into the battery - but this will lead to degradation in battery total capacity.
As somewhat of an extra trivia on Li-ion batteries, Motorola has apparently managed to get batteries that have nominal voltage at 3.8v and max charged voltage is around 4.3v as opposed to 4.2v.

Hopefully I can state this in a way that doesn't scream "I don't know how to use teh search!"
I calibrated my battery stats using the free app on the market after flashing darkside. My phone used to charge to 100% on the indicator (4200+ mV). Now, a couple of weeks later, it charges to the same 4200-and-up charge but the meter tops out at 92%. Two days ago, it was topping out at 94%.
I've re-calibrated using the app, draining it down and charging fully up. Same result, 92% max.
I've wiped battery stats using CWM immediately after charging fully (verifying the charge is above 4200 mV). Rebooted. Still at 92%. Actually, now it's reporting 90% with 4128 mV.
so if wiping stats is a "useless operation", what gives? How is it possible that this method apparently fixed other users' miscalibrated battery meters stuck down around 30-40%?
Try this:
1. Charge as much as it will charge
2. Turn it off and take out the battery
3. While the battery is still out, plug it in and wait for it to show the battery image with the question mark
4. Put the battery back in (do not turn on yet) and let it charge for an hour
5. After an hour, turn it on, unplug, and report back
Note: On step #4 when you put the battery back in it will probably only show like 5% or 10%, just ignore that and let it charge

in cm7, charges to 98% normally, but sometimes takes hours to reach 100%.
I hope i'm not hijacking this thread, but since we are talking about mV i thought this might be a good place to ask....
I've been having problems with my battery levels for a while, i've tried all the voodoo to try and fix it but i can't get anything consistent.
here is what i get....
i have battery calibration app installed, sometimes it will read 4200mV and be 20% charged. Other times it will read 100% charged at 3700mV, it's all over the place, and trying all the suggestions to fix the battery life don't seem to fix it.
another thing i have is it will discharge from 100% to 5% within an hour but my mV will be at 3900+, then it will sit at 5% for another 8+ hours then the phone shuts off, so i plug it in and it says 5%, i let it charge for a minute or two and it's at 20%, i turn it on and it shows that it's above 3700 or 3800mV.
so the phone thinks it needs 3700+ mV to run, but not always, sometimes it will go down below 3600mV and still run
A couple questions
1. can someone post their mV reading at 5%, i'm guessing it should be about 3300
2. what is the max mV that you have....is it above 4200mV (mine never is)
FYI information i've tried fastboot -w, cwm battery wipe, deleting the battery stats file manually, even formatted /system and other file systems to make sure it was fresh

Ok,
I did this and my battery starts off at 100% and all appears to be fine. The next time I charge, it only shows 83% and it is reading 4200mV which should be a full charge. Do I have to do this each time? Is there any other solution? I am running CM7 stable and the battery is an aftermarket one. Could this be the issue? Thanks in advance all.

One trick I've found is unplugging the micro-USB and plugging it back in immediately. When I do this the 4200mV usually drops to the low 4100 range and the % continues to increase.
Only caveat is you'll have to keep doing this until it reaches 100. It takes a while since it seems to get re-stuck at every 1-2% intereval. A pain, but it's a work around from having to pull the battery. :silly:
I have the same issue too but DO I ALWAYS HAVE TO DO THIS METHODS? My battery level drops day by day (becomes %92 max) from %100.
I'd had the issues you explain for AGES.
I'd heard that buying a new battery wouldn't help. But I bought a new, official battery off eBay and I've not had the issue since. That was a couple of months ago now... not saying it will definitely work but at worst you have a spare battery...
What works for me... Charge up as much as possible, then use root explorer and go to data/battd/ and delete everything except the file "uid" then reboot... Should be good to go...
Hope this helps!

This definitely worked for me. I was having repeated issues that full charge/drain calibrations didn't fix. This did.
I had the same issues with charging it ,but i foudn out that the only failproof method of chargin it by using the oem ac adapter and the oem usb cable if you dont have the cable the nokia cables shoud do the trick but the samsung one does not work i dnno exactly why but i tested it myself.

100% agreed.
Never heard of a 1950 battery for sgs2, best bet go with the 2000 mah one, there is a whole thread about it.
Thanks guys, I imagined the same thing. I will be checking out the 2000mah and the 3500mah. My phone battery used to give me more than 20 hours now it hardly lasts 4 hours.

i think that, what you need is to sync your battery, plug in and let it charge till 100%, after that, leave it charging 30 min. more, now, still conected to the power source, go to recovery mode, and swype the battery stats, and after it turn on, un-plug it, and now do 2 full charge cycles, that means, let the battery drain out 100% and let it charge till 100% without interrumption(power off the phone, and then plug it to the "wall"), do it 2 times, and now you'll notice a better battery performance:good:

Thanks, I will try to do what you said. Since I sometimes charge the battery with a battery charger and not with the phone.
Edit- I did what you said and I noticed that the battery does in fact holds a longer charge. I bought this battery on ebay and I am waiting to receive it. http://www.ebay.com/itm/270992164008?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
I have bought from that seller before, it seems a very good price for it.

Actually that doesn't do anything at all for Galaxy S2 devices.

That's not a very informative reply, lol
Fortunately, I know what you're referring to, which is a post by a Google engineer that wiping battery stats has no affect on battery life.
Hello,
put a new battery into my Nexus 4. It's got slightly more mAh, 2250 instead of 2100 mAh.
Phone works but battery indicator is showing the 'empty' battery icon and it doesn't change no matter how long I charge.
What can I do?

I would recommend calibrating the battery using the following: https://www.androidpit.com/how-to-calibrate-the-battery-on-your-android-device
The non-root instructions should still work (fully discharge and fully recharge, etc.) but anything Android specific will fail since we're not in Android. (then again, if you can get access to the Android LXC container somehow [try lxc-attach -n android with root privs], they may work.)
Other than that, not sure what else you can do
It's all right now.
Turned out that the broad band cable connection is a little sensitive. You have to bend/fold it because it is too long. Depending on how you fold it you have or you don't have a proper connection.
Second point: I had to use the original charger (1.2 mAh)! First I had one with 2 mAh which gave me the "red light of death". LED blinks, nothing else happens.
