I have done a search and found dozens of threads on this topic, but none of them comes to a conclusion.
This problem has been around since the s2 and happens at random to many brands including iPhone.
I have replaced the battery, wiped and reflashed the stock rom, calibrated, ect, but the problem persists.
It appears that the saturation and trickle modes have stopped working. When my other phones hit 100%, the charge continues for a few minutes, then goes to maintenance mode. When my s6 reaches 100%, it instantly stops charging and the battery % begins dropping several percent.
This started after I tried the battery charge limit app from Slash. Before this I could let the phone idle for 2 hours while still reading 100%.
I'm surprised this 10 year old problem still hasn't been solved. Hopefully xda members will change that and I can give my s6 every drop of desperately needed juice to get me through a long day.
Thanks to all in advance.

Alright, before you tell me to remove batterystats.bin and move along read this carefully.
I've had my HTC Legend for about 8(?) months now. Around the same time, my mum also bought one. I rooted mine, flashed CM 7.0.0, up to the newest nightly now. She left it as she got it, only upgraded to Froyo when the update came out. Everything is working great, except for the battery statistics.
Around 4 months ago my mother first complained about her battery not charging to 100%. It got worse over the weeks, and the battery level also started dropping faster and faster. It has gotten to the point where, when she gets it off the charger in the morning, it's around 52% (Even though it's been charging for forever, and should theoretically easily be on 100%). After about 5(!) minutes of using the phone, it will have dropped to a 2% battery. Battery life, however, is hardly suffering. She can just walk around with a 2% battery for the rest of the day. Obviously the batterystats are totally ****ed up. After 2-3 months my phone started doing the same, except it does it less severe. I can only charge to 50~60% as well too.
Around this point, I started looking around, and found about how android saves it's battery levels. I rooted and flashed my phone, and using fake flash, I booted into Clockwork recovery, mounted /System (S-on phone, can't edit system when phone is on, still no s-off for hboot 1.01..) and removed the batterystats.bin. I did in a couple of ways now, including the build-in option and using Android Commander. My phone, however, still won't charge past certain numbers.
Now my questions to everyone here is: Did anyone else have problems like these? Any solutions you'd like to suggest? Are batterystats/total voltage also saved somewhere else?
I'd like to point out that the battery itself is not damaged or anything. When my mum's phone had these problems, and mine didn't yet, we tested her battery in my phone, and it would charge to 100% just fine, and the levels weren't messed up.
Her problems started around the time she flashed Froyo from the official update. I can see how flashing a new rom messes up the batterystats.bin, but apparently that's not the only file being wrong?
Any suggestions are VERY welcome.
Tl;dr: Phone battery won't charge past 50% or so, battery level drops to 1% in 5 minutes.
EDIT 1: My mum send her Legend to HTC to get it ''fixed'' THREE weeks ago. She got it back today, them saying it was fixed. After a good 10 hours in the charger it still won't go to 100%, and after 30 minutes the battery levels dropped from 70% to 1%. I think it's quite shocking how HTC can say something is fixed without even trying to charge it to 100%.
you can try this, can't hurt
Turn your phone on and charge it for 8 hours or more
Unplug the charger
Turn your phone off and charge it for one hour
Unplug the charger
Turn on the phone and wait 2 minutes
Turn your phone off and charge it for one hour
Unplug, turn it on and use as normal.

Thanks for the reply,
sad to say I've already followed steps like these atleast three times. Including charging without entering pin, when off, when on, etc etc. Still, thanks for the suggestion.
no such problem yet ... but i'd be interested to know if you were able to resolve it... it cant be a coincidence both you and your mom 's battery levels acting up.

Could be so, but I don't think we're the only people in the whole world to have this problem. I'll keep this thread updated with any information I might stumble across and any other solutions tried. If anyone could tell me where the maximum values for the battery are stored in android it'd be great, seeing how deleting the batterstats.bin file didn't help, there must be another file in android tracking battery..
Hi,
so you're not alone. My Legend is showing the exact same symptoms.
I bought my Legend used via ebay and the seller told that the battery won't fully charge. No problem i thought, just buy a new battery.
Even with the new battery it won't charge more than 60% and it decreases to 10% in 5 minutes.
Just had a test. Even with 60% power at the beginning and 10% after 5 minutes it still was working for 80 hours!
unfortunately i don't know when the probs started to occur. My legend is also with the official Froyo flashed.
regards
Mario

Everyone seems to have this problem since Froyo. HTC fixes it by replacing the motherboard, which basically means they replace 90% of the phone... So basically, there is no real fix around. :/
seem like hardware fault..

Could be so, but it seems strange as the problem starts occuring after flashing to froyo. [Even though going back to eclair doesn't seem to fix it..]
My appologies if this question has been answered somewhere else, I could not find any other threads with a similar situation.
My phone was dropped and ever since then it has not shown me the right battery level. It will charge on USB or AC up to 99% and stop. I connected it to AC power 30 hours ago and it never gave me the green light. This is after a full drain and then recharge. It did however stop charging at some point. I noticed no light was on, red or green, turned on the phone and my battery had gone from 99% to 41% in 22 minutes. I plugged it into USB and it appears to be charging back up. My widget now shows 84% with 4334mV (i dont know if this is right or not).
It is not an issue with the battery. My wife has the same phone and I swapped batteries. Mine works fine in her phone and I have the same problem with hers.
My other issue is that when I use the phone off the charger it will not show me the level accurately when it is draining battery. Example being, I unplug the phone at 99%, within 5 minutes I'm down to 92% (i know this is not unusual because of how the batteries charge). But, I will stay at 92% for hours and hours, with moderate use of internet, phone, and apps. Then it will fall from 92 to 60 ish in a few minutes and do the same thing. Sometimes it will tell me that I'm getting low (under 15%) other times it just turns off a second or two after the notification. If I plug in the phone and turn it on it shows me 1% and charges up to 99%.
In the few minutes I have been typing my phone charged up to 91% with 4336mV.
I was running ViperRom ICS when the issue started. Restored it back to Stock with no root and the issue remained. Now I am running Mean Rom ICS with the same issues.
I have cleared the battery cache in recovery too.
Any help would be appreciated.
If you kiss it. your phone will love you and it'll be all better. NOW KISS IT AND TELL YOUR PHONE YOU'RE SORRY FOR DROPPING IT! LOL!
Based on my experience with batteries of all kinds, it sounds like one of the cells may be damaged. Best bet is to get a new battery. They are decently cheap for a good one. Im actually looking for an extended unit myself. If you come across one, please PM me.
Thanks
That was my first thought but when I swap my battery with my wife's battery I have the same problem. Both batteries work fine in her phone but not in mine.
Sorry to bring this up again, my bad. But seriously you are not the only one with this issue.. I had the same problem since stock, swap battery didn't help either.
Hi guys,
I just got this phone but it's having a weird problem. The battery % seems to drop off in big jumps instead of gradually.
For instance, I also have an Xperia Play, if I run the LED as a flashlight, I can see over a few minutes the battery % goes down gradually.
This new phone, Samsung Galaxy Q, if I run the flashlight, nothing changes in a few minutes. But if I check back after locking the phone a few minutes later, it shows a battery drain.
Another example, before I went to bed, I had it charged to 100%. When I woke up 7 hours later, I checked and it was still at 100%. I checked after I got dressed a few minutes later, and it just dropped to 90%. During my trip to work about half way while playing music, half way to work, it was down to about 86%, kept checking, and no changes. When I got to work at my desk, the battery hit 77%.
My battery graph when I goto battery use is basically this, straight line....DROP, straight line...DROP, etc.
Has ANYONE ever had this problem?
I have seen this happening when the battery gets older.. is this a new device with a new battery?? If it is a new device, your battery might be damaged. you should better get it replaced.
Hi all, thanks in advance for your help.
I've been having crazy drain trouble with my stock battery for about six months now (the battery is currently 15 months old). It's draining like crazy, it goes from 100% to dead after two hours of browsing/reading an ebook, even less if I'm playing something like Candy Crush Saga or Asphalt 7. I tried going through several apps such as Wakelock Detector, Better Battery Stats, tried recalibrating the battery and haven't found an obvious culprit - other than the screen, which alone uses up something between 40 and 60% of the battery.
Is this normal?
Sometimes, when the battery is at 30% or less, it will just drop by several percent in the matter of seconds, for example if I switch on mobile internet. If I'm using the phone at <10%, the screen will sometimes start flickering, and the phone will freeze and remain like that until I switch it off manually.
In addition, if I connect the phone to charge, in about 70% of times, it will incorrectly show something like 45-55%, even though it's depleted. Then it remains like that until it's charged up to that point and then the percentage starts rising again.
Honestly, I'm tired of having to bring my charger everywhere and ending up with a dead phone whenever I need it for a longer period of time. I don't remember the last time my battery didn't die by the afternoon
I'm facing exactly the same issues and yes, honestly I believe it's time for a new battery.
After 15 months, assuming daily charging, you would have approx. 450 charging cycles. Lion batteries are known to age and to lose capacity after so many cycles. Try a new battery, if the problem persists, have your phone checked.

Hello, I was told to post my question here. I'll just copy/paste:
I have a Samsung Galaxy Beam (GT-i8530) and recently it started to show weird behavior when it comes to the battery level. It drops really fast and takes forever to charge up to 60% and then jumps to 100% in a minute. It also happens that when I leave it charging it says 100% but the moment I remove the cable it shows a lower percentage such as 38% or 56% (it happened again today, I left it charging for almost 3 hours and when I checked it said 100% but when I removed the cable it changed to 34% and the warning message appeared telling me the battery was under 50%). At first I consider it to be a problem in the battery but Galaxy Beam comes with two batteries and the problem kept the same even after I've used the second battery.
I've searched around but everywhere I look it gives those charge/discharge cycles guide and I've tried that already but it didn't work at all. For one no matter how long I keep the cellphone charging, even if it says 100%, if I restart the cellphone it will starts with 94% instead of 100%. Is there anything else I can do to fix this? Should I try the charge/discharge cycle again? Could rooting my cellphone and doing the cycle calibration again but with a rooted device and the calibration app for it help instead of doing the calibration for unrooted devices or it's unlikely that will make a difference. I don't know what else to do.
Thank you.
Edit: It got worse. The battery was at 45% so i put it to charge. When I came back it actually dropped down to 28%. I tried to restart the cellphone and after I did it started with only 15% instead. I've checked the cables, the chargers and the USB door, there's no problem with any of those. Tho recently sometimes when the cellphone is charging it starts vibrating non stopping and it's not the cables contact because it does not show any message saying the cable disconnected.
HELP!
