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%.
Sent from my MB860 using XDA App
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.

When I charge my phone it only charges to 99%. I'll leave it in for a while, come back and it's only at 99%. Either charging in the wall, or on the computer. It used to make it to 100% then all of a sudden it just stays at 99% regardless how long it charges. So the charging light always stays on and never lets me know when it's fully charged.
Any idea why?
Thanks.
Mine does that too once in a while, randomly.
But the Sensation would do that to randomly.
Dunno why.
Battery is strange...
I get that too. But eventually it will get to 100%. There has been times where it was charged to 100% then suddenly drop to 99% even though it still plugged in.
Did you get your phone recently? I'm thinking its because the battery needs to be conditioned.
Mines always does that, as soon as I unplug it it jumps to 98%. Im hoping ARHD fixes this
I've installed Battery Widget (from Market) and it reports 100%. I plug in every night and in the morning it reads 100%.

New Amaze Android Revolution HD ROM by mike1986?
This happens with many devices. I have not seen this yet on my Amaze but I am sure at some point it will happen. Try turning the phone off and charging it to 100% then power it on also try running the battery all the way down and letting it charge to full UNINTERRUPTED over night. If those dont help you can always try another rom with better battery management or go into a t-mobile store and get a battery replacement if your battery is still under warranty. Hope this helps
HTC does this on a lot of phones. It is a safety default to keep the battery healthy and safe. I had this issue with the Evo. The only way to fully charge a battery is to have other a wall charger or a SBC kernel.
its the best sense rom known to man in my opinion.

My stock battery is 3.8v, and it only goes to 100% if I charge it in the phone. If I use my wall charger, it shows up at 99% when I put it back in my phone. I have two aftermarket batteries that show about 98% when charged from the wall. I am thinking that the phone charging circuit is set for 3.8v, and might possibly overheat the aftermarket batteries (3.7v). I saw one review that said these batteries melted the top of his SIM card. I'm not planning on trying that; I use the stock, charging every night, and swap the spares in if I run out of charge during the day.
I just remember hearing the same stories when I had my evo. You could charge for hours and unplug it and it would almost immediately drop to 99 or 98. So my previous statement may or may not help.
I charged mine over nite and woke up to it being 99%, left it for another hour or two and it hit 100%. I would say to leave it a little longer to get that last 1%.

I find that if my phone its powered off while charging, it shows 100. If powered on, it shoes 99.

this is normal for lithium ion batteries...it also depends how the manufacturer perceives the battery...some manufeacturers say that your phone is 100 percent but it might only be around 95-98...overcharging lithium ions are bad...also some manufacturers say you have 10 percent left while you might actually have 15 or maybe to percent left...this is a fail safe method to shut off the phone and keep the battery from draining completely WHICH IS REALLY REALLY BAD FOR LITHIUM IONS...OVER CHARGING THE BATTERY IS BAD TOO...perhaps htc's thresh holds are a little different and actual to the real battery life.
also not a good idea to use your phone or any lithium ion device while its charging
powering off your phone to charge it overnight is the best idea to give you lithium ion a long life but this is not practical. this is why it says 100 percent when you turn off the phone and 99 when you're phone is off....it confuses the phone: " A portable device must be turned off during charge. This allows the battery to reach the set threshold voltage unhindered, and enables terminating charge on low current. A parasitic load (which means using phone or turning screen on while its charging) confuses the charger by depressing the battery voltage and preventing the current in the saturation stage to drop low. A battery may be fully charged, but the prevailing conditions prompt a continued charge. This causes undue battery stress and compromises safety."

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.

This was common on my droid x for so long while flashing but is it a good form of practice on the Rezound? The reason I am asking is I flashed Bamfs Cubed rom and my charging led goes from orange to green at 98%, never making it to 100. Would it be wise to go ahead and wipe battery stats and see if it fixes it? I presume there would be no harm to the system or battery in doing this.
Thanks!

Don't agree. Just like I don't agree with people saying task killers are bad. I guess with the way I use my phone I get different results. I have always noticed better battery life wiping battery stats. Now it could be that the OS will fix battery stats itself over time, but when you ate bouncing around a different rom every two days then the OS doesn't really get a better feel for the battery.
Plus...I came from the evo 4G where we uses trickle charge kernels and I want those back. Never had better battery life than when I had those. Was doing 35+ hours a charge on the stock battery.

Haven't bothered since I never could get the thunderbolt devs to try it. There was "reported" cases with no proof that it caused some batteries to go bad. Even then they were cheap Chinese batteries that 2 people total I think it was claimed went bad.
It was always nice to pull your phone off the charger in the morning at 100% instead of it showing 100% and you pulling it off the charger to say 92%.

Well there is the fact that Li-Ion batteries can not be trickle charged after reaching full charge...
Well they can, but it will hurt the battery. And that isn't me talking from a few bad battery posts... but from knowing how Li-ion batteries work and charge... and reading engineering papers about Li-Ion batteries.
Luckily trickle charging is slow and most people only leave the battery on the charger over night at most. Plus they charge while the device is running and using power. Should someone leave the charger going for 24 hours, with the device off, we would probably be hearing about a fire.
What is probably happening with these trickle charge kernels is:
The phone is going to use some power at all times, the trickle charge is probably just enough to keep the phone running and preventing the battery from draining slowly.
This works because there are two ways to handle full charge status while the charger is still connected.
1) When the battery reaches full charge, the battery is isolated from the device preventing the device from draining the battery. The device then runs solely off the power coming in from the charger. (this method would not benefit from trickle charging, and forcing the battery to continue charging will at best slowly hurt the battery over time, and at worst cause a fire/explosion)
2) When the battery reaches full charge, the charger is isolated from the device. The device runs off the battery until the charge drops to a certain level (usually around 90% or so) before charging starts again.
The second way is how the Rezound does it, and most other devices as well.
The first way requires the ability to switch instantly to the battery from external power without any drop in voltage. This is difficult to do, as a drop in voltage could cause the device to crash/freeze, so many devices do not use this method.

Well if the device was off then the kernel wouldn't be running and trickle charging the battery but when turned on and the battery fully charged they would very slowly charge the battery as it dies. So there should be no risk of the battery catching fire. And anyway, the way the evo trickle charges worked is they would charge your battery to a certain voltage. Once it hit that voltage it would stop charging until it dropped. So it wouldn't be hard to protect the battery.
Did this for 6 months on the evo with no issues.

If ithrow my phone on the charger with the battery in,it will charge to 100% after the external charger says it was fully charged. I've tried letting them die all the way and charging them back up in my phone, tried wiping battery stats at 100%, and even tried taking the battery off of the charger the second the fully charged light turned on. But no matter what I do when I put the batteries in my phone, it says 87% lol. Both batteries do it, my old one and new one. Any suggestions?

Shot in the dark, but my battery meter on my phone routinely goes down on a restart. Maybe the act of booting up your phone causes the drain.
Or, maybe the charger is not fully charging them to preserve the battery.

Go into recovery and format battery stats. That should fix your problem.

I tried that man, and it didn't help. Maybe the external charger just can't fully charged the batteries
