Weird battery charging issue (stuck at 83% in all ROMs)

So,
I've flashed three or four ROMs over the last week (with a few different kernels) and they're ALL having the same issue:
I use the "miagi method" to fully charge the battery, but when the phone is ON, the blue LED comes on when the phone is still reading 83%. I turn it off, plug in, and after a few minutes it's at 100%. I've wiped stats, flashed ROMs and kernels and the problem persists.
I don't know if this is having an actual effect on battery life, but it sure is annoying.

I'm going to assume you've been to this forum?
Personally, with all the phones, re-roots, re-flashes, and Odin flashing I've done I've had no need to do any battery edits, so I am limited on experience. My question to you is this: Does it hang at 83% for a while when in use, or does it immediately begin to drop percentage as if the battery never charged beyond that point? I know that sometimes after a reboot, my phone will go from 50% to 20%, but then hang at 20% for hours since it is in actuality at 50%.
If none of that helps you at all, my suggestion is this. I found the same thing for half the cost several months ago elsewhere if you look. It came with 2 batteries, one for me and my wife. The included batteries are notably not quite as good as the original samsungs. However, carrying an extra battery gives flexibility, and the wall charger does a faster and more effective job at charging any battery.
Plus, then you'll have a battery while you're other one charges!

++ on This .... I've used that calibration method (the 2nd one, off method) and it worked well for me.

hi i can solve this just follow simple steps
discharge your battery upto 17 percent
than use back camera with flash on take pictures with flash your phone will power off suddenly after 2 to 10 pictures.
just plug in charger issue is resolved your battery will be charged upto 100 percent

Bad battery, wake issue or usb port/cable?

So after some time I've been battling with my battery life through the day. Few months back it was great, Id easily get a day no problem! Then I found I had a wakelock issue and had that fixed.
I now suddenly have almost multiple things going on at once but first a small back story.
Went to bed one night and had it plugged into the wall. Went to bed at 60% and woke up and my phone was down to 6%. I thought, well the usb port is bad or the cable. Took it into the sprint store, they of course say "it looks like its charging just fine, the light is coming on" (the light was on during the night too).
They checked the battery and they said it was bad. Im wanting to take it to another store and have them check, because either: they didnt want to replace me with a new phone or replace the usb port if thats bad.
1) Bad battery- in a matter of 30minutes (during my lunch break at work) my battery dropped from 63% to 14%- only used 3g for facebook and sent 2 text messages. And my phone is undervolted and underclocked
2) Possible bad usb port- I plug my phone in all day at work, and 90% of the time the screen is off. The % of the battery doesnt increase, but maybe decreases slightly (I have data and everything turned off while at work because I get no data signal).
3) wakelock- so suddenly I'm getting a huge percentage of system usage of 54% in my battery stats. A few months back it was maybe 1%? I flashed the .img that sets the wimax, PRI, NV, etc to what fixed the issue back then. Im just confused how this has come back now when I havent even updated anything related only my rom (MIUI 1.8.26).
So I've ordered 2 2000mah batteries off ebay- I wasnt going to pay $40 from a battery story across from the sprint store (as they didnt have any stock, only extended batteries).
If anyone has had a similar experience, or would know what is the culprit would love to get feedback. Hopefully I can get this fixed soon. Maybe just a trial and error.

Something really strange just happened. I checked my phone just now and the battery is at 98% and just maybe 30minutes earlier it shut off because of low battery
What I explained before about using my phone on my lunch break was only 2 hours ago and showed 16%.
I always wipe my battery states when I update my ROM or install a new kernal.

Don't wipe battery stats if you don't have a full battery, it'll keep your battery from charging fully.
It may be the battery, but since you're getting new batteries you'll know then. If you didn't get an external charger, I'd suggest doing so. That way you can guarantee that your extended batteries get a full charge, and you can switch out a dead battery with a fully charged one if you keep having problems. The usb port on the Evo is crappy anyway, but if the light comes on and stays on & you can transfer data through the usb port then I doubt that's the problem.
It could be hardware failure, but wait until you get a new battery and have properly calibrated to come to that conclusion.
In the meantime download Battery Monitor Widget, that should show you your true battery capacity even if the system will not. You don't have to use the widget, you can just open the app. Once you see that your battery is fully charged, calibrate your battery properly. Wipe battery stats at 100%, let it drain until it shuts off, charge to 100% without breaks, and you should be good to go.
Good luck!

Thanks for that!
I just bought a battery from BB to hold me over (50$ for a 1750mah battery?! )
when it charges to 100%, should I go into recovery, or use battery calibrator (app)?
Ill install that battery monitor too

BMW has the feature to wipe stats. I also recomend to look at the reports and judge when the battery is full by looking at mV. 4200mV is full charge. Then wipe stats FIRST, then unplug and run down completely, then recharge fully with out unplugging.

Ya just noticed BMW had that feature. Forgot I had a menu button. LOL!
This battery I got at BB is a "1750mah".
You know what I realized what might be the issue? Back a few weeks ago, I bought an extended battery to use to take videos at a concert. At that point I wiped the battery stats at 100% of the 2500mah or so battery..

Galaxy Nexus batteries wont fully charge

Last month i rooted my phone and installed buggless beast. Since then my phone wouldn't fully charge. I bought the extender battery, same problem.
Last night i wiped it again and installed aokp. Still wont charge past 63%.
I attached a screenshot of the phone info.
I've looked at the other posts about similar issues but it hasn't worked out yet. If anyone has any other ideas I would appreciate it.
Thanks,

Charge the phone to 63%, and then leave it plugged in for a few more hours just to make sure it is charged as much as possible. Use the phone until the battery hits 0% and the phone turns off. Do this 2 or 3 times if possible. If this doesn't solve the problem, go into recovery and wipe battery stats.

[Q] battery dies too soon

I have an epic that was working fine. I got a new phone so it sat with the battery dead for a little over a month. Now I gave the epic to my daughter and the battery is all wonky. It will charge up to 100%, but when I take it off the charger it will last anywhere from 20 minutes to 4 hours, which I got the other day with no use and airplane mode on. Now here's the wonky part. It only goes down to around 88% and than goes dead. If I plug it back in it says it has about 80% charge. But if I don't plug it in and just try to turn it back on it acts like it doesn't have enough juice. Now on this phone I'm on cwm 6.8.x or something like that and you can't wipe battery stats so I didn't try that. So I guess my next step would be to flash another recovery and wipe battery stats. I did just flash the peoples ROM 2.2 (I think was the number) just yesterday and wiped everything else for a clean install. Has anyone heard of or experienced this? How can I fix this? Will wiping battery stats work? Also, the battery was great, I could easily get all day out of it with average use just a month ago. Please and thank you.

Nothing?

This community is very small now since this device is old. You need to have patience regarding replies to threads.
Sounds like you need to replace the battery. Look on Amazon and eBay.

I haven't heard of this happening before, nor has it happened to me. Even though some would advise against it, i'd 'calibrate' the battery just to see if that would fix it. If that doesn't fix it, I have no idea.

From what I recall there was a lot of different opinions about the battery wipe in CWM.
If you google it there should be a video that shows you how to use it. I think you drain the battery until phone shuts off then charge it full, unplug it wait 10 minutes, charge it full, then turn it on and wipe battery stats. Then run phone dead again and charge again. Don't really want to charge it until after running it dead.
I used it a couple of times and it seemed to help but people say it has no affect because the battery stats are in the rom or something like that.
I also have heard that after you load a new rom you have to give it some time and the battery will get better.
I have never experienced what you are so sorry I can't help.
I would guess most would say its the battery buy a new one cause it sounds like the battery is only charging 20%.
I still have my stock battery after almost 2 years. It will get me through the day if I just make phone calls and text, but I have to keep a charger handy if I'm going to use the phone for other things. Sometimes my battery will drop if I reboot. It will be at like 30% and when I reboot it will come on with 15% and tell me to charge it.
They say the 1800ma model will work in this phone and I would check into that if buying a new battery.
Well good luck!

The battery was working fine two months ago. That's why its weird to me. Wiping the stats didn't help. I guess a new battery is in order. Grrrrrrrr

If it was the original battery it already has some miles on it and if it sat for a month or two dead in the phone then it's most likely toast. You will get best results with li-ion batteries during the first 300 to 500 charges, so after a year or two the battery will naturally loose it's ability to hold a charge, that's just the nature of the beast. A new battery will do wonders!

The percentage that is displayed is usually directly correlated with battery voltage. So 3.200 V would represent 100% and I think it is 2.6 is 0%. So what sounds like is happening is the battery has a bad cell and jumps from say 3V or whatever is 80% right to some voltage below 2.6. A new battery "should" fix this.

check that 4g isn't on or google talk isn't on. Google now is a big battery waster too. For unexplicable drains, check for a defective battery and if all else fails a clean wipe/install. I've had just about all of these issues on the 4 epic's we own.

[Q] How many people have had battery problems with the Galaxy Tab S 10.5 T800?

I've spent the entire evening tonight trying to find out why I'm getting very erratic battery performance on my Tab S 10.5. I've seen the battery jump and drop 10-30% within a half hour, I've seen the battery percentage go UP from 55% to 67% after rebooting it while it wasn't plugged in, and all kinds of other battery level weirdness. I've even seen it lock itself at random and randomly reboot both when plugged in and when running on only battery.
Tonight, I had had enough and did a factory reset, and it got WORSE! After the reset, it went from 10% tom 17% when I unplugged it. Once I did, it rebooted itself and the battery dropped to 0% and shut itself off!
I've seen other people on here complaining about the same battery weirdness, but the threads seem to mix people talking about different Galaxy Tab S tablets. My question is if I return this to Amazon and get a new one, am I likely to have the same problem? Will it be better? Worse?

For me, the biggest drain is the screen and I have it at a very low level. I put it into ultra power saving mode last night before going to bed. The batter level this morning was fine, but GSam Battery Monitor said I had the screen on for 8 hours, whereas the built in batter app shows otherwise.

I'm seeing alot of battery issues for people that root. You play. You pay.

I haven't rooted my Tab. I'm running stock.

Here's another example of what I was seeing. Once it dropped down to 0% last night, I left it plugged in and left it alone. hen I looked at the battery meter, it didn't show a gradual increase in battery level, it showed a huge spike up in the middle of the night. So it charged very slowly, then at some point jumped around 50% or more and continued to charge until it showed 100%.

Today my T800 did something similar, it was full, then unplugged, started to use it and it went to 92% in just 15min so I was like WTF, plugged to the charger and then immediately jumped to 99%, I unplugged and did a reboot and it once it was back was at 99% again, so I charged again to full and I will see later how it's behaving.
I did notice that when this happened it was warmer than usual
Mine is not rooted.

My T800 doesn't behave like that. I'd definitely return it.

Mine is doing the exact same thing. Also loses all wifi connections and I have to put in the passkey every time it reboots. It started about a week or so ago. I think I'll just return it.

Guys, see this thread. Tab S 8.4 T705. I had issue with battery too and i managed to settle it by this way.

Do you even know what rooting is? If you did, you'd know that rooting on its own does nothing to the battery, not only that but it CAN'T do anything to the battery

my battery problems solve (maybe)
Finally after reading dozens of post and trying all kinds of apps to solve the draining and rebooting of mt Tab 5 10.5 t800 I decided to replace the battery so I watched a video on you tube about how to replace the battery and took the back cover off.it was easy I used one of my guitar pics and before I took the battery out I remembered seeing a post here on xda about the battery plastic connector not making good contact so before I took the battery out i disconnected the white plastic connector it just pulls up and off and used a q-tip with some electrical cleaner on it and cleaned the contact and plugged it back in, I charged it to 100% witch I could not do before because it would stop at 98% and put the unit through the paces playing games and videos and doing every thing i could to drain the battery and the first thing I noticed was the battery life was about 5 times greater and it did not drop or reboot yet after 7 hours im at 54 percent battery life .. the screen is more responsive and the unit is running smooth as butter. I am REALLY excited and hope this is the answer to my problems because I really dont want to buy a new battery and find out it does the same thing.
