Hi everyone,
Im running cherryblur 1.4d obviously rooted and unlocked. I've been running it like this for over a month now and its been great but a week ago my phone stopped charging up to 100% when I let it charge overnight. It reaches 90% and stops. I have a charger that charges the phone and an extra battery at the same time and it has worked great since I got it and the only way to get the batteries to go to 100 is to take the batteries out of the phone and put 5hem to charge in the battery slot. Please help me guys. Its not the battery because I have another battery and it won't charge fully either. I'm going crazy with this I've looked everywhere and haven't found anything
Charge your phone to its fullest capacity (I guess that would be ~90 for you)
Wipe battery stats in recovery, reboot.
Let the battery drain completely, until the atrix shuts off. Watch a bunch of videos or something.
Recharge back to full capacity, hopefully 100%

You might also want to try charging the battery with the phone switched off, when it reaches 100% remove the battery and wait for the no battery icon to appear on the screen. Then re-insert the battery and leave to charge for another hour or so.
After doing this, boot into CWM and clear the battery stats. This should fix your problem.

Mine won't charge to full unless I'm using the charger that came with it, ALL other chargers stop at 95-98%.

Make sure the other chargers are kicking out at least 700ma the moto charger kicks out 850ma.
Any less than 700ma and you'll not get a full charge, a lot of 3rd party chargers only 500ma which will not work too well.

^ This. Most people don't realize that they can't use just any charger with some phones, this phone being one of them. It requires a certain amount of juice running through it to charge properly, which is why if it's dead it won't charge from a USB port.

Thank you guys I'm in the process of trying the first suggestion I'll see if it charges fully tonight
Also if you are swapping batteries, the battery stats will continuously get messed up. It will be trying to configure the two as one and that could make this a reoccurring problem for you
Sent from my MB860 using XDA App
Oh that could be it as well because the second battery I got drains quickly (or it shows that way) and spends the other half of the battery life (8~10hrs) at 1%
Ok guys turning it off and charging fully and then unplugging and plugging again, and wiping battery stats after worked perfectly. Thank you!
For anyone who has this problem you can wipe battery stats with the battery calibrator program or in CWM and then you must drain the battery after wiping the stats.
So I charge my Galaxy S2 to full (or at least, it says it's full), unplug it, and it says it's only charged to 60%, or 43%, or something random. I plug it back in, and off it goes, starts charging again, this time usually up to the "proper" 100%.
On top of this, the battery drain is very fast (10-15% overnight)
So, believing it's the battery, I get a replacement. Same thing.
I then learn that the reason might be because I flashed Lite'ning ROM while not on full battery, and that it just needs a battery calibration.
Ok, so I do a battery calibration - I charge it to full, drain it to 0%, then charge again. Take it off the charger, plug it back in to make sure it's full and...what do you know, the battery meter shows it at about 20% It continues to charge for about 4-6 hours after this.
Help? Is my phone faulty, or am I just not doing the calibration correct? I don't think it was like this before I installed Lite'ning ROM. So I'm praying it's not the phone itself?
The only other thing I can think that it might be, is the fact that it's a UK Galaxy S2, but I'm using it in Japan with a Japanese charger. Though I don't think that's an issue.
Any help would be very much appreciated.... not only does my battery not charge to full in one go, but it has **** life afterwards
did you try removig battery stats from recovery mode?

Yeah, that's what I meant by "tried the battery calibration".
Charged to full, wiped battery stats from recovery, then rebooted.
Try using app battery monitor widget, and check battery is actually charging it to around 4200mV, and discharges to around 3500mV at approx 1%.
100% is not full, it will continue charging for quite a bit after to around 4200.
At least you will know that the high and low scale is correct, and can monitor in between.

So I charged it overnight via AC adapter (with the phone turned on), woke up, and the phone was at 4%!
Seriously, what the hell?
Phone was indeed reading close to 3500mV via Battery Monitor when it was almost empty
Any help?
Try charging via usb, much slower than ac though, then check again.
Don't drain battery to 0%, certain reports indicate not good for the battery, others say no worries. Try 1% so the phone doesn't turn off.
Although the huge jumps in battery level indicate a battery issue; If still no good, try a different ROM, and recalibrate. Also try in flight mode overnight and check results.

Thanks for the suggestions man, I appreciate it. My main concern is whether or not it is a problem with the phone itself - the place I bought it from has a ****ty returns policy and won't exchange it or anything. So I'm hoping like hell it is something I can fix myself (new battery, new charger, different rom, etc etc etc).
As I mentioned, I'm currently on the latest Lite'ning ROM with Ninphetamine kernal I believe. Just did a factory reset/data wipe via recovery mode, thinking it would get rid of lite'ning rom and the ninphetamine kernal, but upon rebooting the Lite'ning rom theme (blue lightning on the icons, etc) is still there.
Anyway, I have it charging on USB now, and I have ANOTHER battery coming tomorrow, along with a stand-alone wall charging unit (that charges just a battery on it's own, not connected to the phone). Maybe I should charge the new battery via that for 16 hours, then stick it in the phone, wipe the battery stats via recovery, and flash a new ROM (say, the new villainrom)?
Yeah, forgot about that also, I have two SGS2 (one in for repair), and each time new have let is charge overnight without turning on before first boot. Then discharge to approx 1% (do not let it die), then charge fully to 100% and approx 4200mV. Quickly clear battery stats with Battery Monitor Widget (menu / stats / SU permission, no need for recovery as you'll waste battery rebooting and get inaccurate reading) and immediately disconnect charging. A new batt stats file will be generated.
At least with this method you'll know your at a "true" 100%.
Also, it may take a number of charge cycles for full battery potential, but don't let it die.
I use Cognition straight "out of the box" with no issues.

Yea, as the title says.
is there a way to fix this ?
THANKS!
I would try re-calibrating your battery. Try this which is straight from my MIUI guide.... (I suggest method 2 as it is the easiest)....
RECONDITION YOUR BATTERY
AFTER FLASHING IF YOU FIND THAT YOU HAVE BAD BATTERY LIFE TRY ONE OF THE METHODS BELOW TO FIX:
Method One:
Use phone till it dies on its own, completely dead.
Charge phone completely, plus 30 minutes longer.
Unplug phone from charger
Reconnect, you'll notice it's not full, charge till it is again.
This is bump charging and NOT something you want to do often, a few times is okay, in my opinion. You could skip the bump charge if you like.
Phone remains plugged in.
Boot into recovery (volumes + power)
Advanced > wipe battery stats, reboot.
Use phone till it's literally about to shut off (or does) Charge till full + Use phone like normal
OR
Method Two:
Download the Battery Calibration app by NeMa from the Android Market

Tell me if this works for you...
A real battery capped to charge at 96% or 97% due to voltage issues that would occur if charged to complete 100%. But samsungs stock ROMS and most other ROMS are customized to display this 100% when its really not at that level. Since MIUI is based off of CM7(and this is uncredited of course), it is not modified in any way and it displays the actual battery life. Which in your case is 96%. Hope this helps.

Hi guys, when i try to charge my battery its stop charging with 90% and never goes beyond that. It starts to happen 2 weeks ago.
Any help would be great to fix it.
Thanks,

Boot into recovery, then go to advanced and reset battery stats, then reboot. Use your phone until the battery dies then fully recharge. If this doesn't fix the issue, you may have a bad battery.

Have you Tried to Recalibrate the Battery?
Sometimes the phone battery monitoring gets out of sync and the remedy is to recalibrate the battery.
You can either try one of the available apps in the Android Market or you can do some manual steps available online(just search for Android Battery Recalibration).
Here is one example, scroll down to Battery Calibration section: http://www.darkyrom.com/community/index.php?threads/guide-battery-life.2551/
I tried wiping the battery stats and calibrating as well but what worked for me was:
1. Charge for at least 4 hours to ensure a full charge
2. Unplug, turn off, and then pull the battery
3. While battery is out, plug charger back in and wait for the battery icon with the question mark.
4. Reinsert the battery (results will vary here, mine comes up as 5% for some reason)
5. Unplug the charger and then plug it back in, it should show as 100% now
6. Turn on while plugged in, wait until fully booted and then unplug from charger (it should read as 100% or 99%, depending on how your battery gauge works)
This is just what worked for me, I am running Navalynt's pi-crust (based on AT&T 4.5.91) so please be careful and research if there would be any issues with other ROMs

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.
