hey guys not a noob but feel like one right now bc i have to ask this.
anyways i have a vibrant running nero 5 w/voodoo. my charger port is iffy at best. i ordered a new usb port off ebay and will be installing it once it arrives.
now the phone charges fine off, however i noticed that when im on it while plugged in charging its loosing percentage. i just finished charging it and turned the phone back on and kept it plugged in to top off the last 4 percent it had to go to 100. and when i check in settings it says 88% about 5 mins later it said 86%
any ideas?
i also did a search and didnt really find anything
I've had this issue since day 1. I've had my vibrant for almost a year now and it's never changed. It's happened on stock and all roms I've used. It seems to happen more when I'm using memory heavy apps or games. I used to play pocket legends and I once drained my battery (while plugged in) so much that I went from %100 down so low my phone died. The charger never lost connection either.
I've also had this happen while streaming tv shows to my phone & using tv out while charging.
Happens to me sometimes. I figured it was a badly calibrated battery. I calibrated my battery and it doesn't happen that much. Oh, and I've learned to not really use my phone when it's charging. Lol.
yea i bought a new battery yesterday. let it die then charged it. drained it and had probs. i wiped the stats and its off charging now sitting at about 92 percent. see how it goes

I've gone through it with the stock battery and my 3000mAz
Are you overclocked at all? Maybe set a charging profile with setcpu to lower clock and/or undervolt if you have a compatible kernel? Not sure, just throwing out ideas... Good luck, hope you get it figured out.
[SOLVED]
issue has been solved. thanks everyone
How did you solve it
it could be an app using the cpu at all times
turned the phone off and let it charge all night and that was about 3 days ago and its back to normal now. it was deff a bettery issue as i have 3 batterys and 2 extended ones and my other batteries would charge just fine. but all good to go now. thanks.
Hi, I'm new to the forum.
Recently, I have rooted my aria with Clockworkmod 2.5.0.7
however, when i switch off my phone to charge, the led light doesn't go out even after i pulled it out from the plug.
Can anyone tell me why?

Did you use Unrevoked or Revolutionary?
Battery stats are jumping and showing inconsistent information
Hello,
I have a strange problem with my rooted and S-OFF’ed Aria for the last six months and I have been trying to find a solution or a fix to the problem ever since.
The battery percentage is always incorrect and never shows any percentage value greater than 30 even after 8-10 hours of charging and drains within an hour phone shuts off. The phone is basically useless for me right now.
I did try all the calibration methods and other solutions (listed below) that I could find in the web and the forums here, but none seem to have fixed the issue.
Soft Reset
Hard Reset
Format System, data, cache partitions
Installed all available ROMs in the community (Liberated, CM 6, CM 7, Stock Original, Stock Update for 2.1, Stock Update with Froyo (2.2) etc).
Battery Calibration of all known procedures (Delete batterystats, discharge fully, recharge fully etc)
Did a task 29 (fastboot oem task 29)
Replaced with a brand new original battery from ATT.
Now with S-OFF, I cannot fully revert to Stock version or send it for Warranty repairs etc (Is there a way to revert to S-ON)?
So now turning on to the experts in this community to help me out and you guys are really awesome in guiding others and fixing things. Hoping to hear from someone.
Btw, I found a similar symptoms and “solution” in the Atrix forum. Please refer link below.

Have you tried wiping battery stats, then just using the phone normally? (not letting the battery totally discharge, etc.)
Did the problem only start happening after you S-OFF, or did it happen before then?
It does sound to me like there's nothing you would be able to do about the problem, except reverting to S-ON and sending the phone in for warranty service. Supposedly there is a method for doing this although I have no idea how complicated it would be. You should probably go to the #liberatedAria IRC channel to ask about how to do it.
Thanks for your reply, drumist
Yes, I tried wiping the batterystats and used the phone normally for couple weeks, still no difference.
The problem started months before I did S-OFF, possibly due to multiple format, flash of ROMs etc. Somehow the phone or the battery doesn't know the correct readings/voltage data.
The max voltage on a full 8-10 hours charge that I have seen is only 3.8 v (new and old battery) and ideally it should be >4 v for a full charge.
Thanks,

Yeah. It sounds to me like the mechanism in the phone that is supposed to charge the battery is failing to charge it above a certain threshold. Either that or the mechanism that measures the voltage is failing. You could figure out which one is the case by measuring the battery's voltage with a multimeter if you have one.
I know this is a long shot, but have you tried charging the phone with a different USB cable, or with a different USB power adapter, or by plugging into a different power socket in the wall (or using a different computer if you are charging through a computer USB port)?
Today I tested both batteries using a multimeter and both had voltage > 4 (old battery: 4.19 v new 4.18 v). I tested this after charging the batteries through the phone, so it proves phone charging is working fine and the batteries are good.
Then I went to CWM and deleted the batterystats, pulled the battery out, waited for couple minutes, put it back in and restarted to generate a fresh stats file.
But the voltage displayed in the phone is totally wrong (3456 mv) and showed 20%, so there is something wrong with how the phone understands full battery voltage and percentage.
I waited for the phone to discharge and shut off (which was <10 mins), then checked the battery voltage in multimeter, it was still good at 4.10 v (lost only about .09 mv).
Is there anything that we can do to override or correct the voltage and percentage in the phone?
Thanks,

my phone is not getting charged, it shows charging but reduces the charging already present. how to solve this issue
Hi.
After flashing a new ROM I could only charge my battery to 64% overnight.
The battery discharged to 23% in about 3 hours.
I installed battery calibration, ran it. The battery then charged to 57%.
This number is now stable even if I reset the battery calibration in CMW.
I think that the problem is that the OS has the voltage settings wrong.
At 57% the battery calibration program says it reads 3825mV. The EVO 3D battery is rated at 3.8V.
So it should be in principle fully charged, right? So why does it read 57%?
(Google play information for the battery calibration program claims that 100% is 4.2V, can it be overcharged that much?)
Do I just need to wait for the phone to settle? Or do I need to somehow let it know that the battery is 3.8V?
Anyone know how to fix this?
Really? Nobody else had this problem?
I have no idea how to fix this.
After the battery is discarged, it charges back to the right voltage 3.8-3.9V but it will read a random % value.
The OS calibrated itself over the weekend to where it would think the battery discharged over 2 hours from full.
Using the battery calibration program while in the OS seems to do nothing.
But resetting the battery calibration in recovery (CWM), or flashing a ROM seems to reset the battery %.
However! It resets to read 64% at full, not 100%.
With a fresh reset like this, the battery lasted me about 7hours (with me playing music for maybe one hour of that.)
When charged overnight, the battery topped at 43% for some reason. (Battery voltage still read 3.9V).
I reset the calibration in recovery and it jumped back to 64%.
I tried two different ROMS. I tried reflashing my hboot. I tried several versions of CWM. Same results.
Any suggestions from anyone? Please?
Edit:
I tried switching the recovery from ClockworkMod to 4ext, but it seems that 4ext did not work on my phone.
I was not able to boot into the recovery menu.
Edit 2:
I tried two different batteries. And I put back the stock recovery. Still wrong % reading.
I don't really want to put the stock hbood back in. Won't that relock my phone?
i have a solution

hi mate, i have an ISW12HT from AU KDDI just like you are and have same problem lf i flash custom rom like smooth criminal or CM 10.1.
finally i got the solution, just go to /system/bin , and swap/copy htcbatt file with htcbatt from stock rom AU KDDI
don't forget to change the permission to -rwxr-xr-x, then voilaaaa.... battery indicator back to normal again.
i hope that can help your problem...
sorry for my english
So I have this annoying problem that my G5 turns itself off when the percent of charge left is somewhere between 15 and 20 percent. I'm not completely sure that it affects amount of time it could operate from the full charge but at least it leads to the following problems:
1) Battery saver is never triggered so losing the ability to use the phone is always abrupt.
2) Battery usage statistics/ time left on battery predictions seem to be totally incorrect.
I've googled and found some ways to calibrate battery without rooting the phone but it seems like they always feature charging the phone while it's turned off and somehow (maybe due to newer android) G5 always turns itself on when connected to charger for me. All the apps for battery calibration seems to do nothing.
So my question is - is there any way to fix this without going to LG tech support/ rooting the phone? May factory reset help in this case perhaps?
Same issue
Very good question and very giid analyse , i have the same problem , i was about to calibrate my batterys but seems to do nothing according to your experience . i m using lg external battery charger , i think using two devices for the battery ( lg charger + phone ) give this problem , i m very confiuesed how to solve this probleme

I second this I got 3 batteries and the cradle 1 never charges to 100% but seems to last longer than the 2 that do charge 100%
I think the cradle and charging throws the calibration way off then think you run 1 batt down till shutdown slap a new one in so the device never gets a charge discharge calibration
Okay I just had this issue on my N10, but I solved it by switching the charger out (yes sounds stupid, but it helped)
I did have this problem on other tablets however and I am happy to share the solutions I have found over the years.
Solution 1: Battery stats.
Plug it in and boot into twrp. If it just keeps showing a faint white battery icon, use solution 2. Now max out the screen brightness, and let it die. Now plug it in and charge it to 100%, boot into the OS and calibrate the battery by wiping the battery stats or grabbing a battery calibration app off the play store.
Solution 2: Different charger/Wall Brick
This was my N10s issue, I tried solution 1 but that didn't help, so I tried switching out the wall brick. I traded my 5 Watt amazon adapter for a generic usb wall brick. My wall brick heats up, yours might not. You know that the charger is a problem when you plug it in and the battery icon is dim, it should be full brightness and doing a little charging animation. I noticed that this generic brick would do the animation so I tried just leaving it plugged into that, and my tablet is now at 7% and going up slowly.
Solution 3: Reboot over and over again
Exactly the title. On my old kindle, the battery would occasionally come up with a real number rather than 0%.
Solution 4: Rom cycling
Flashing a different rom. I had to do this on my old tablet a few times, but it would fix it sometimes. Honestly any rom will do, just keep cycling.
Solution 5: Replace the battery
Lastly you could just replace the battery. a battery is about 40$ on amazon, so this is a bit pricey. This is a last resort and will most likely fix your problem, and if it doesn't, you'll at least have a nice full battery for when you do. I've never done this, but I've read about people having success when they do.
Tried most of the items you pointed out and unfortunately changing the battery was my only success.
However the new battery is also starting to give away. Using it as a photo frame so battery is not a issue, the yellowing of the screen however is..

'ole N10 user here, ordered a $23 replacement battery just now then hoping it resolves basically a dead battery. I own lots of tablets but a "why not" feeling if $23 makes it as-new.

I can confirm that there is something strange going on on the nexus 10 hardware. When I received my second hand nexus 10 ,it shoots down at 40% . Now after 3 months, I don't know why but trying to charge in twrp, let it go drain all the battery in twrp, and charging when it's turned off completely recovered the charging hardware ,because I know the battery can't recover from a bad state . Now it turns off at 0% , and it's not only a calibration effect, it lasts longer than before. I charged mine with an aukey charger and some good quality cables . I never used the original wall charger , because the aukey has 5 connectors and I use it to charge all my devices

I fixed it, turns out it was the charger I was using. Guess I was lucky, my Nexus 10 is a champ now.
I fitted my Nexus 10 battery. Bought the battery [URL="https://www.youtube.com/watch?v=yru4k62qdEU"]here[/URL] and used this video guide. It was very easy took me about 30m watching and re-watching the key steps, the ribbons being the one to pay particular attention. Wow, though 17 screws......
I have Android N via Pure Nexus unofficial build and its performing well. Its relatively slow cpu by today's standards does make it stutter more if I make it do a few things at once, relative to my Pixel C, but I love the forward speakers and good now for a spare tablet. I just did similar thing for my Nexus 7 2013.
The Pogo pins is finnicky takes a few connection attempts til it works. I can see why 2 models later (after Nexus 10 was 9 then Pixel C) they moved to USB-C 3A 5V 15W its far quicker.
I've replaced the battery, changed a few roms, use different chargers all the time (whichever is Handy), and tried resetting the battery stats. No joy so far. Always shuts down at 30%.

I had the same issue with a new battery. I charged it up to 100% then went into twrp (I'm running linage) and wiped the cache. Touch wood it seems fixed.
I'm having a good experience once I opened up my N10 and replaced the battery. I'm getting very good battery life, on full brightness about 8-9 hours.
I like the screen form factor for watching videos like MP4 or Netflix. It is so good I turned off my Pixel C at 60% charge to make its $600 expense I spent 18 months ago last as long as possible for when I need its performance which is when traveling.
The recharge performance is the biggest weakness, I have to plug in the Pogo cable and leave it alone. I have a bit of light bleed on bottom right corner. Audio via built in speaker is a bit feeble. Running Pure Nexus which eventually will get Oreo.
I bought my Nexus 10 when released. Battery still lasts till the end and charges fine to 100%.
But this screen is so bright, I always kept it at lowest brightness. No screen issues and no battery issues and use it everyday since new.
I bought my Nexus 10 the week it was released. The battery eventually stopped holding a charge, and I replaced it. Now my battery indicator is stuck at 100%, which is as bad as 0%.
I'm about to try a different ROM. Hopefully that will help.

Fully charge it, wipe battery stats, reboot
This is a common problem when swapping batteries on any device. It took me a while to respond because MeowDude is my old account.

I tried letting the battery drain until it shut down, then recharging to 100%. I think it's better - not sure.

Last year my Nexus 10 was due for a new battery. I swapped it for a new genuine one, but since that day the Nexus will shut down at around 80% charge. It's not that this percentage is incorrect (it happens at around two hours of light use), but it somehow sees 80% as 'empty' and shuts down. I've tried all solutions mentioned in this thread but to no avail. Any ideas?

Since I replaced my battery, my Nexus 10 stays charged for days. If you've replaced the ROM (so you know it's not a software problem), then it must be a hardware problem. Hopefully you just got a bad battery, and it's not the Nexus 10 itself.
