[BUG] Phone won't full charge battery (with At&t 4.1.83)

don't know if someone point out this already..
impressed by the short battery life of my Atrix, definitely lower than i expected, i make this try, and that's what i found out..
if you full charge the battery (phone shows "charged" or "100%" if you charge it when off) , then pull it out WITHOUT disconnect the usb charger, the phone reboots, then it shows a big picture of a battery with a question mark in it.. if you put in the battery again, the charge is stuck at 60%, and it takes about another hour to get the battery full..
so it seem that the phone think that battery is full, and stop charging it, when in fact it isn't..
if someone had a Motorola Milestone before, this was a known bug, due to the motorola kernel, who was solved only by some later Roms..
i haven't yet tested if using this, battery life is effectively longer, (just discovered), but with Milestone it was. a lot.
maybe our battery life can be better than it is now, if we can make phone recognize the full charge when it realy is..
P.S. i'm on stock At&T froyo.. if this was solved by latest kernel and Gingerbread i'm sorry for the useless post..

i can confirm my battery life improved after charging my phone in that way, like it was with Milestone and according to what i expected..
in fact, to charge a 1900 mA battery with a 850mA/h wall charger, it MUST takes, in a perfect world without energy dissipation, about 2h20' from discharged.. don't know about your, but my Atrix normally takes less, so it seem more than probably that it isn't really full charged
still waiting someone who test this on Gingerbread.. hope this issue's gone..

Just tried it on GB 4.5.91, when I popped the battery back in it said it was at 5%. It's charging up now, I'll update when it's done charging up...

If you have CWM you can clear the battery stats, then use Battery Calibration to fully charge and calibrate. I usually leave the phone charging for about 15 minutes after I get the fully charged message, then calibrate.

So you reckon his battery isn't calibrated. If yours is, can you perhaps try what he suggests & report back? That'd be useful!
(I'm calibrating mine right now otherwise I would have tried..)

Same here, how did you go?
Mine seems to be stuck on 5%
If I boot the phone, its 100% and 4200mV but as soon as I unplug it it goes to 99% and 41** mV

That's where I was for a long time (stuck at 5%), so I decided to calibrate the battery then give it another go. Right now the battery is draining, hopefully by tomorrow I'll have some results worth posting...
EDIT: After recalibrating, draining, and recharging, the battery still says 5% when you pull it and replace it. I'm charging up overnight, will update again tomorrow.
2ND EDIT: Charged for about an hour and a half, and it went up from 5% to 15%. After another 7 hours, it was still at 15%. Looks to me like a glitch in how the phone reads the battery, but don't know how much it's actually affecting battery life.
Today's my first day trying Green Power, so we'll see how that does.

so it seems Gingerbread acts in a different way..
maybe this bug was solved, with latest kernel, since if you're stuck on 5% and don't increase, phone is definitely NOT charging... it seems that it doesn't well recognize the amount of charge, but probably it is full..
i repeat, mine goes from 60% (when i pull and put the "charged" battery) to 100% in about an hour, bringing the total time of charging to 2h 15', that is how it needs to charge a 1900mA @850mA/h...
it's maybe simpler to check if it was solved or not.. if your phone takes about that time to full charge, we can assume that's act properly..
will try the calibration, thanks for the hint..

N7 Powers off when battery reaches 20%

So I thought this was a fluke the first time then I was just able to reproduce the issue again. Once the battery level reaches 20%, the tablet will either shut itself down using the built in shutdown command or will just simply power off as if it doesn't have any power left at all.
I've charged it thoroughly and have even drained the battery down to 1% in the past but this keeps happening now. Any ideas?

this hasn't happend on my nexus yet but something similar happened to my LG Nitro HD. I basically rooted it and tried some battery calibrating apps on the Play store. In custom recoveries there's also this option to wipe batter status which i think might fix it but i've never tried it.

The battery gauge can be quite inaccurate. From what I have seen, I think Asus cut some corners in calibrating it for the specific battery chemistry - which makes things even worse.

It's not as if, there is no power left. The battery gauge simply had a wrong estimate of the remaining charge and suddenly the battery voltage collapses (happens very quickly towards the end of the discharge curve) and the N7 shuts down.
Messing with the battery stats doesn't do anything useful.
If you do a full charge / discharge cycle that may help a little with battery gauge accuracy. The battery gauge does some recalibration when doing that.
After a forced shutdown, fully charge and make sure the tablet sits around fully charged for at least 1h (e.g. just plugging it in over night will do fine). Then do a full discharge cycle with the N7 not plugged in at any time (normal usage will do just fine).
Those battery calibration apps don't anything useful, beyond getting you to run a full charge / discharge cycle.

Never happened on my Nexus 7, which have been taken down to 14% more than 10 times in the last 2 month. If what are suggested above don't work then use this tool to restore stock then Warranty return it or return it to store if you still have time,

Wonder if this is what happened to me last night. Was watching a video and it just shut off like the battery was dead. I wasn't paying attention to the battery but was almost positive it wasn't anywhere near zero yet. Never had the low battery pop up on me either. Hopefully it was a fluke...

there are many battery calibration issues/posts in old N7 forums. it also happened to me once in first couple weeks. what helped, I think, was shutting down the device completely with a little bit of battery left and just keep it unplugged for a few hours. Some say to preventively repeat this exercise every now and then..

I had tried completely discharging it and then leaving it to charge overnight a handful of times without any luck. I ended up just restoring it to factory state and getting a replacement via Google Play Warranty Support. The new unit works just fine. It's an 07/2013 build unit just like the first one if anyone was interested.

by any chance do you use a qi wireless charger?
I have encountered a weird bug where if I charge my nexus 7 with a qi charger to 100% and leave it on the charger itll screw up the percentage/battery stats. with my situation, itll lock my battery % to 100% and wont go down until i go into twrp. If i just go into twrp and not recalibrate the battery stats, the percentage would be off and my nexus wont show the right %, so my nexus would shut off at random % instead of the normal 1% or 0.

I can confirm this!
Did help on many devices for me with battery calibration erros...
Last one was a Galaxy S2 last weekend - turned of immediately, showed 0% upon start.
Took battery out for 4 hours, put it back in then and voila... 92% and everythings fine again.

Battery not charging past 80% after battery change

Hi folks,
I recently got a new battery for my S3 neo to replace my rapidly deteriorating original.
since the switch, i've been unable to charge EITHER battery up to 100% without waiting many hours for it trickle charge up from 80%.
here's the background:
i switched out the batteries when the old one was fully charged (since i was going to store it).
when i put in the new one, it read 84% when turned on again, i thought this was acceptable, since the battery would have been stored for a while before i bought it.
however, when charging this battery up again, it would hit around 76-77% and start trickle charging, as if charging from 95 to 100%
im not really sure how to fix this, and i have tried wiping cache, and running the battery down to 0% and charging from there. i have my theory, but am not sure its at all correct!
my theory (please tell me if i'm wrong)
when the battery jumped from 100% to 84% following the battery switch, that reset 84% to "fully charged" somehow
this would leave being fully charged as 1764Mah in the battery instead of 2100Mah
and by charging to 84%, then switching in a 100% battery this might be somehow reversed?
Would really appreciate any ideas people may have, since the already poor battery life (2 hours screen on) has now gotten even worse!

Please Help moto x play huge battery issue

I used samsung fast charger for 4 months and battery life was all good , then i lost the charger so i had to charge the phone with a "not so fast charger" that took ages to charge my phone.
Never charged to 80% , and battery drain was serious.
That's when i got worried that the charger ive been using might have destroyed my battery.
So bought the "turbopower 15" charger for my MXP and at first it heated up my battery more then 60* (serious overheating issue)
After 2 or 3 charges i figured it only heats up after the percentage is 50% or higher or when i use it while charging.
And now it drain my battery like crazy!,
I just restarted my device into recovery right now and it was 45% but by the time i booted up to recovery it said 25%. How CRAZY DRAINAGE IS THAT??, Please devs help me.
Its like i dont need a stopwatch my battery drain a percent per second.
Im using purenexus 7.1.2 by @GtrCraft witb stock kernal

Thanks god. my battery is back to normal after charging it a couple times with the turbopower 15 charger. now when im home i never let it discharge past 70% this way it stays in good health.
when it went bad it discharged 10% in 20 minutes now its 10% in an hour

Battery health on 6t

Does anybody noticed the battery health of 6t draining faster ..
I'm talking about capacity of battery
After 4 cycle of accubattery app it shows around 3600 mah battery but my phone is brand new its been a 10 days till i bought .. is my battery faulty or is it okay ?

Same here. Battery quickly drains to 96% after unplugging from the charger. Takes half an hour max without using at all. After that normal drain.

May be new update is buggy ?

Since the last release I decided to stick with Nova Prime and no Google Companion. Before I was on stock launcher and turned off shelf. Charged to 100% and over night battery drained to 99%.Right now I am at 77% with 2 hrs of screen time and been unplugged for 16 hrs.
I would think that shelf or Google Discover is a battery drain for sure.

I don't think so. It's happening on custom ROMs as well. For me it started from one day on another. Weird thing but I think that's the ACTUAL capacity of the battery. You'll actually never have 100% battery when unplugging from the charger after some longer charging. It just shows you that.

I noticed as well. I think its because of my extended use of fast charging as isn't good for the battery. But I thought that the heat was going to the charger and you should use the charger that comes in the box.
However, from extended use of my 6T and my previous phone the OnePlus 3. Dash charging affects the battery even though heat doesn't go to the phone, it affects the battery health. And you shouldn't use it especially if you want to keep the phone for 2+ years. I've been using my 6T since December and my battery health is around 70%?! I only been using dash charge as well for both of my 6T and OP3. The reason I upgraded was because of the degraded battery in my OP3. From this, I'm gonna send my 6T back to OnePlus for a battery replacement, so that I get a brand new battery and from now on I'm never gonna use dash charge and instead gonna use quick charge 2.0 chargers as I don't have a apple 5V charger. But this should still be better for long term, even if it is a form of fast charging. All Samsung phones since the S7 have been having this quick charge standard. Using fast chargers is convenient, but it is not good for long term and it is just another scummy way for companies to reduce the longevity of your device and make you buy a new one. Tbh Dash Charging or Warp Charging or any fast charging should only be used when you're in a rush and you're phone's battery is low

Thanks buddy noticed this issue too .. while charging on regular charger it's fine shows almost 3700 as health but on dash charger it shows much lower

So i figured something interesting ...
The ideal capacity of oneplus 6t is 3700
But rated or we can say usable capacity is of 3610mah ..
So according to that accubattery is almost right ...

Hey!
I got a new device one week ago. Felt the same. As soon as I unplug, it starts to tick. Battery backup is up for 24 hours only. But I have seen many say that it lasts longer. Suggestions? ? I did one update after getting the device. That's it. Even before it was the same situation.

In the beginning I had a similar issue. Drain up to approx. 85% went fairly quick,but afterwards the drain will improve drastically. Takes some time I think

It did for me at least. Otherwise it's an app issue.
I only have the "issue" that battery goes from 100 to 96% fairly quick but I don't really care. Drain afterwards is normal and getting over 10hrs SOT easily anyway.

Mine does this but I noticed that if I reboot my phone every morning before taking it off the charger, this issue goes away. So I'm guessing there is some sort of trickle charging happening once the batter reaches capacity. I also notice if I take the phone off the charger as soon as it hits 100%, battery does not drain to 96% quickly as well. Must be something with the way one plus software works with charging
