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

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.

Has anyone run across this? Lately when using Battery Calibration app, as soon as I unplug from charger I drop from 100 to 96...( happens frequently now) is this just a sign my battery is getting weak?
Sent from my SCH-I500 using XDA App
Nope - that's actually the correct behavior for a well-calibrated and healthy battery. When you charge your phone disconnects the current when the battery is full, and for the next half hour or so it reads 100% but the battery is slowly discharging. This protocol preserves battery longevity. After a while it will top the battery off again. Long story short, 96% charge shortly after unplugging is perfectly normal.

thats funny, my device stays at 100 percent after I unplug it from the charger, then discharges normally. It never drops to 96%, sounds more like a kernel issue to me.

When still running Froyo my Fascinate always displayed 96%-100% upon disconnection after full charge, even if left overnight. After update to GB, the longer it remains on charger after reaching 100%, the lower it drops after disconnecting. Sometimes it's dropped from 100% to 76% as soon as charger is unplugged, if left on charger for too long.
I was informed on another forum that there's trouble with the trickle charge function on GB and it's likely not to be corrected.
Just thought I'd pass that on, for what it's worth.
the battery does that on purpose so it doesn't overcharge and decrease battery life.
in other news, google android people have said more than once that battery calibration does nothing, wiping battery stats will not help anything at all.

I normally Charge it while Battery Calibration is running, then when it hits 100%, I power off the phone and let it finish charging with the power off then onces its "Truly" fully charged I turn the phone back on get into Battery Calibration then press the calibrate button
What's the general consensus on this i.e. Google engineer basically debunking the necessity or benefits of calibrating one's battery?
http://tweakmydevice.com/2012/01/no-need-to-calibrate-android-battery/
,this is how i calibrate my battery,before i have 45min of standby it will decrease from 100% to 99% but now it is 2hours & 34min before it go from 100% to 99%,i felt the drain after 2 weeks of overusing my phone (1week playing paladog and 1 week flashing different roms,kernels and theming my phone with different launchers),
- Charge your phone to 100% while it’s on.
- Unplug it from the charger, power off, then charge for 15 minutes with it in a powered off state.
- Unplug charger from phone. Power it on, and then charge 15 minutes while the phone is on.
- Calibrate battery using battery calibration by NéMa then unplug charger reboot.
- Power on, charge for 15 minutes then unplug.
- Finished.
note: deleting battery stats(calibrating) don't increase your batterylife said by others and it is just a placeboo and i believe in them,but it fix my battery drain so why don't we give it a try,there is nothing to lose,battery drain is so annoying.
,thanks to NéMa for the awesome apps,

That was from LEWA OS, one of the best rom at that time...:good:
First and foremost, a Google engineer debunked the idea that batterystats.bin has anything to do with how the phone charges. By deleting it, you're actually inconveniencing yourself, as there will be a short period in which you won't have accurate stats.
Secondly, the O1 has a lithium ion battery. Lithium ion and lithium polymer batteries don't need to be calibrated, as they have no "memory" effect (you can read more on that here).
Moreover, these batteries have built in charge circuits that protect and regulate the battery. Ever wonder how the phone knows the battery temperature? It's pulling it off the charge circuit. That same circuit also prevents the battery from ever being overcharged or discharged fully, which is why that convoluted guide about calibrating your battery by draining it to "empty" and then recharging it to full doesn't work. Worse yet, intentionally draining your battery is actually counter-intuitive, as lithium-based cells wear more as their percentage of discharge increases (you'd be hurting the battery in your effort to calibrate it).
Your instructions aren't detrimental, so if it works for you, go for it. However, based on my understanding of these batteries, it seems to me that this procedure is inconsequential.
Besides, a new battery for the O1 is only $6 USD on Amazon or Ebay.

My XPERIA X10i charges up to 100%, then stops charging until the battery drops below ~93% and then starts charging again.
So depending on when I unplug the charger, I may or may not have a 100% charged battery.
Clearing the battery stats and checking again can't hurt.
Just give it a good charge for up to 12hours
If you disconnect the charger and then reconnect it again, does it start charging again from 90% upwards?
It won't charge the device when the battery is indicated to be 100% charged, so there still could be a problem.
Good chance to buy a 1800mAh Mugen Power battery. Mine gets from 1 to 3 days depending on use and has a heavily under-clocked CPU over night or when not in use. Seems to spend over half it's time in deep sleep.
Hi there, wiping battery stats doesnt actually do anything in relation to battery level. It was a myth and all placebo effect.
I remember your screen name from a while back when I still had my x10, so it could be the battery itself starting to die.
You could get an extended battery (or just a new stock battery). I had the 3300mah and it was awesome.
