[Q] Battery being weird - One (M8) Q&A, Help & Troubleshooting

My phone keeps acting weird while charging. Some days I can charge it without turning it all the way off and other days doing that doesn't do anythng except slow the phones power loss. And other times if I charge with the screen off it'l charge to like say 27% then i boot it up and it says 66% then drop to 21% right away and after a reboot it'll say six percent and when i shutdown it'll say 13%. So my battery is just jumping everywhere and I was wonder what I could do and should I reset the battery stats. I'm running Maximus HD 11 but i had battery issues starting sunday when I was running cm 12.1.

I have the same issu with 12.1 ..i can not even charge sometime .. .the usb charge is someyime working sometime not working

try and reset the battery stats..

[Q] Strange battery percentage drain in 10 minutes.....wtf

This morning after I got ready I took my phone off the charger (it had been charging all night and was at 100%) and walked upstairs. About 10 minutes later I turned on the phone and it was at 67% and going down. I had flashed a new rom yesterday and as quick as I could I did during the drain I did a NAND restore. Could this have been actual battery drain or is there something wrong with my phone/stats. Could my phone have stopped charging at 50% and then just said it was 100%? What should I do? Is there anyway to avoid this from happening again?! I cant go to work with a battery at 50%! lol
-.- Searching is your friend.
The Evo has never trickle charged properly. Trickle charging is when you hit 100% battery while charging and the phone will continue to keep the battery charging and maintain this 100%. So 100% > 99% > 100%.
The problem is the Evo doesn't do this. Once it hits 100%, it switches to battery. It will run off the battery till it hits about 90% and then charge again. Some even say it will NEVER charge again after it hits 100%. So when you unplug it in the morning, you end up dropping extremely fast from 100% to 90%.
There are kernels in the development section that fix this issue but there are people who say it will break your phone or burn your battery out faster over time. When trickle charging, your phone will get hot as its constantly draining and charging. That can lead to a burned out battery as time goes on or a damaged phone. I personally have three batteries. I still tried to use this and noticed a drastic improvement but my phone was also pretty warm when I picked it up in the morning. Its up to you.
Also you might want to see if you have your 4G radio on. That is probably the only thing I can think of that would drain it that fast. Either that or your GPS is on and theres an app running thats using the GPS receiver.
i'd say a 30% drain in 10 minutes is unnatural. it wouldnt be myns rls4 that you flashed, would it? this is experianced by some as a "first day side effect". just fully drain and fully charge the battery a few times and you will be fine.
It could be that it just needs a couple drains and I don't want to quickly point the finger at an app that you are using. A lot of times if I actually charge my phone it will be on 92% when I wake up. 67% is a stretch unless that was 10 minutes of a game or YouTube..but still. Drain the battery a few times and see what happens.
i was thinking maybe its some kind of battery stats problem? Could that have caused it?

Charging problem! slow or no charge..

ok, over the last week or so ive had this issue, gradually getting worse...
my battery will charge to around 40-45% and then charging will slow right down.
two hours later, it will be on around 50% if im lucky, and about 3 more further hours before i hit 60% (this is some of the time, other times, it just remains on its current charge%)
if i leave it overnight for about 10hours or so, highest it goes to now is about 73%, but this is rare, usually 45-50%ish.
ive tested with htc ac wall charger, htc usb, blackberry charger, car charger and a random microusb wallcharger. all have same issue.
when tested with two friends desire hd's on different days, my battery charged perfectly, and at the normal gradient speed over the % range. and my phone reads it correctly at the 100%-98% when back in my phone after change back.
i thought it was down to my phone, just dont know if its rom or hardware. shud i factory restore, or claim on insurance?
i have another issue here...http://forum.xda-developers.com/showthread.php?p=18480603&posted=1#post18480603
which also applies to the question of restore or insurance...
thanks
What Rom are you using, i am using runny 2.2 only 62% charge in 6 hours
9 hours later on battery only upto 68% i have amazing battery life now
i'm using runny 2.2.....left it on charge for 2 hours with phone on, but wifi and everything off and it had only gone up 2% ! !
Turned phone off and plugged in charger, 30 mins later, only went up 1% ! !
72% charge at this point.
So took it off charge, put it in my pocket, went upstairs to bed, turned it on to set alarm and it said 100% on battery....weird!!

Lol this is an issue with calibration. The battery is charging but the software doesnt report it.
You have to charge the phone for as long as possible so you know it is on 100% whether the software says it or not, go into CWM, wipe the battery stats and then let the battery drain fully until it shuts down by itself. Then plug it in and leave it until you know for certain it is at 100%. If the green light comes on leave it for an additional half an hour. Then it will be fixed.
ive only recently got this handset, as last one was replaced on insurance a month or so ago, and its runuing on stock rom with latest updates....?

[Q] Battery status not updating while charging.

Since last few months I have observed that when I charge my phone, it isn't updates properly battery status(ABOVE PATTERN LOCK).
After 82% or 92% it seems stops updating battery status. Then it takes hours to go 83% or 93%
Today when I was charging it, it was updating properly in proper interval of times (25% to 82% I think in 2:30 to 3hours). But again got stuck to 82% and then it took 2 hours for just going on 83%. So I though of restarting phone.
When I restarted my phone it showed 100%.
Although restarting solve this problem, but I think even if it shows 82% it stops charging when it actually goes 100%.
Has anyone else faced this on Wildfire?
Is it because of some widgets?
Is there any solution for this?
My phone have stock 2.2 rom
I have same problem like @Lara_Shadow - battery don't want to go to max charge. Goto 70-75, sometime 78%.
My GF have Wildifre with CM 7.2 Stable, but the mestery is that when I change battery with my and plug-in into my phone android says that is fully charged. My have 20-25% but her WF says there is only 1%.
Have someone any idea what to do with that?

Insane battery drain after charging

So I've had a problem with battery drain lately that has only seemed to get worse. After leaving my phone on the charger overnight, I unplug it to immediately get battery drain of around 25% on average. The phone will get hot and keep quickly draining unless I turn it off for an extended amount of time. Today was the weirdest problem yet. I unplugged it from a full charge only to have the phone instantly go to 1% battery and die. I'm running paranoid android as my rom. What could be causing this and how can I fix it?
How long have you had the phone?
About a year now, got the phone last October.

Poor battery since 6.0.1?

So I updated my phone tonight and after it used 30% in an hour or so. All I was doing was using FB on it. Prior I played PAD for 15 minutes and it hardly used 5%. I've wiped cache, cleared app cache, and now I'm working on a full discharge from 100%. The battery is brand new and it was getting better life prior to the upgrade. So much for 3x better battery I guess?
After clearing caches I left it idle ofer night. It used 13% for 20 minutes of screen time. and then it used 3% idle over the 5 hours I slept. Still seems a bit high on usage for screen time but idle is great.
So I discharged it completely and now its losing power fast again. The battery was 100% unplugged it and turned it on and its 97%. So I turned it back off and checked it and its also showing 97%. Charge it back to 100%, turn it on, its on 100% but loses 1% in a second. Plugged it in while onand it took like 3 minutes to charge that last 1%/ No idea why. The battery is brand new and got 2 or 3 days on idle before, now it reports 20 hours. what happened to that 3x better battery? What else can I do to sync the battery properly? I also noticed 100% is not 100% until the phone tells me battery is charged.
Again this battery is brand new and my life with 5.1.1 was pretty good.
I've been having poor battery calibrations in EPH7, though my battery is still what came with the phone.
There are days I can get to about 5? left before the phone dies, and there are days it dies at 15?..
Already tried charging all the way till full while the phone was off, still the same. It's random, but I just generally expect the phone to turn off as I come close to 15?.

That sounds like a bad battery. I can get my phone to drain down to 0% before it dies, but the battery usage can be erratic.
After some testingm the first 5% (95-100%) does down fast but after that it can go a pretty good while. Not sure why. I left the screen on with max brightness, turned on NFC/wifi/bluetooth and just left tons of apps running and it took 4-5 hours to get the battery down to 20%. the life is in fact great just not properly synced. No root makes it more of a pain to calibrate.
So I charged the battery offline and it got to 100%. I switched it on and it shows 97%. What the hell has marshmallow done to my note?
last post. If I charge the phone formt he OS it reaches 100% seemingly properly and doesn't discharge quickly. Not sure what marshmallow screwed up.
I had the same issue with my battery draining quickly after the upgrade. I backed up all of my data and then performed a master rest of the phone and then went into recovery and cleared cache as well. Once it booted back up I reloaded all of my apps and reconfigured all my accounts and my battery acts normal once again. It was a pain in the ass to do all of that but it did work for me so hopefully it works for you too.
