Hi everyone,
My G3 (D851 T-mo, not that it likely matters) yesterday shut off dead at about 40% battery reported as remaining. I was early to a movie and fired up Angry Birds 2 to kill the time. Just as I was about to start playing the phone went black. Tried turning it on, nothing at all happened. I had noticed the battery was at 41% just a minute or two before. Usually this means I have PLENTY of juice left.
After the movie I tried turning on the phone; again no response at all. Pulled the battery, replaced it, still nothing.
I got to my car and plugged it in to charge on the way home. After a moment the screen came on and gave the "powered off charging" screen showing 71% battery remaining. Huh. 71% ?
I was driving for about 10 minutes, got home, and plugged it into a wall charger. At this point the phone (still powered off) reported 51% charged.
Shortly thereafter, I booted the phone up and it reported 55% charged on the usual battery % notification.
I charged it to completion, and all seems normal, but I'm worried about it dying again at ~40%. I frequently run the phone down to 15-20% before charging in the normal course of events. Is there some battery calibration I should run? Or, is it time to get a new battery (and if so, any recommendations...)?

I've noticed that since I upgraded to CM-101 (I'm now on 106) that my battery takes FOREVER to charge. For instance, last night I went to bed around 1am and put my phone on the wall charger it was on 17% and when I unplugged it at 9am it was only 67% charged.
I'm at work right now and I plugged my phone about two hours ago and it was at 50% - two hours later and it's at 64%. Before it would at least be at 80% by now.
I haven't installed anything that I would think affect this (no major notifications, etc..)

Check your wake time, it could be that your phone is staying awake and sucking up the juice that should be charging it. Also, does your battery die quickly? A possible culprit could be tango, it has a bug that doesn't allow the phone to sleep.

I'll check out watchdog lite and see what it tells me. It did it again last night. I plugged it in at 12:30am and was at 23% - this morning I woke up at 9am and it was only at 89%. I turned it off and left it charging another 15 minutes and it was up to 96% when I turned it back on. With light usage (20minutes using Music and checking email/SMS message a few times) it's now 11:42am and my battery is down to 51%. It hasn't been this bad in at least a couple of months.
The only that I did over the weekend out of the ordinary was use one of those AA powered portable-chargers that I bought at a drugstore because I was down to 16% and wasn't going to be near a charger all day/evening. Could that have messed something up with my battery?
Worst ever
Mine too!!! this is crazy!!! my O2X take forever to charge and this not my first smart phone... i had HD2, touch pro, desire... all HTC. The only thing is this samsung n dual-core... doesnt make sense!!! so far anybody has resolution for this? HELP!!!!
Same with mine. Did you guys do the OTA update? I did it to watch Green Hornet and it wasn't doing it before.
I plugged it in at 1am @ around 50-60% and woke up at 8am and it was only @ 88%!
I used the wall charger, so it should be getting 1 amp.
UPDATE:
f*cking duh! ooops, my bad! I was developing last night and left STAY AWAKE WHILE CHARGING enabled!
running the 2/16 release of CM11, battery meter is acting funky, but battery life seems normal. I have no idea if it started with CM11 install or just out of the blue. couple week ago after 13 hours of running on battery I noticed the meter still said 100%, then about an hour later it said 52%, and 30 seconds later 12%, battery low warning, and 15 seconds later it did a clean power off. plugged in, powered off charging said 9%, and was 52% again in about 30 seconds.
battery still lasts all day, but I have no idea how drained it is until about an hour before it's dead. it also won't actually charge unless the meter says it's below 100%, but plugged in it also doesn't drain it more. using an app to monitor the battery, it rarely shows above 3850mv, and will hover there all day long going up and down 300mV or so, but then late in the day it'll break from 100% around 3700mv and the % starts dropping.
so, what's going on here?
so, left on charger overnight (as I do every night), status app said USB power on but discharging. came to work, plugged it in (as I sometimes do), battery said 100%, again USB power and discharging.
unplugged to go to lunch, 54%. sat down to eat, 65%. few minutes later, 70%. from there it started dropping at a normal rate. used it heavily all through lunch, only went to 58%, and seems to be charging normally now as well. I'm so confused... it's been wrong for at least 2 weeks strait through multiple charges and reboots.
What about 'calibrating' the battery?
if it does it again I'll to find time to drain it and then fully charge it powered off, but with an inaccurate reading of what the charge is it was very difficult to fit that into my schedule.
it seems to have calibrated itself now, as it's been fine all weekend.
so the questions is now: what caused it, and why did it fix itself some weeks later? I certainly didn't do anything anywhere near a calibration cycle.
So my phone battery has been acting crazy since the last update. First it dropped to 0% instantly from a 30 or 40% a weeks ago and just now it went from 20% to 0 in a second. The battery doesn't seem to be bulging. So before I buy a new one, has anyone else had weird issues? Just now I was charging it and decided to take out the battery. It jumped from 14% to 55% charge instantly from reinserting the battery.

It's a bad battery. There have been many people coming on here describing your same symptoms, but it doesn't matter what update they're on. In the end, it always turned out to be a bad battery.
So it's not an update issue.

I have had same issues and I noticed it's beacuse I was charging my phone via portable power bank.
When this happens I just drain battery dead, recharge phone to 100% while its turned OFF.
Unplug the cable, turn it on, if it doesn't show 100%, I just plug the charger again to refill it to 100%.
After that for several chargers no problem, it goes slowly to 1% and then dies on 0%
Hi,
Bit long story, I know, but I'll have rooted Galaxy tab 3 8.0 and the problem for few weeks has been that the battery has gone mad.
So, when battery dies and tablet shutdown and I try to start again after a while there's no enough juice to even start fully or if it starts it shows 1% and shutdown immediately. That's as it should be I guess.
BUT, if I plug into charger when batt is empty and it has shutdown it suddenly shows very random percentages like 12%, 45%, 52%. 75% etc totally random even it should be something like 0%-1%.
If I then fully start it android shows that same big percentage but batt won't last a minute if I plug off the charging cord.
If I then plug in the charger again when it has shutdown it may show totally different percentage than last time but also dies as soon as I plug off the charger.
First time it could be like 12% but immediately after shutdown suddenly 71% etc.
Also when I try to fully charge battery it often jumps from around 70%-80% to 100% and while discharging it can suddenly drop from around 45% to 1%.
I have tried many things like wiping batt stats and fully charge from empty to full with power off/on, restart after full and charge again, leaved it screen on to slowly kill the batt etc.
So is that batt just badly worn after many years or is that "battery information file etc" somehow messed up that it can still be fixed/calibrated?
Ouh, and my current rom is AICP 12.1 (Nougat 7.1.1) if it matters.
Thanks
Phone was at 98% battery. Did a reboot as I do every morning, and when it started up again it showed 91% battery. I know reboots don't take 7% battery, so what gives?
My Pixel 2 XL has been having some battery reporting issues, I noticed that when I took my phone off the charger it would lose 15% very quickly then stabilize. Rebooting would also cause a drop in indicated battery %. That's my guess. Investigating to see if it can be fixed by doing a full charge/discharge cycle.

I've also been seeing this issue! I will also be letting it do a full cycle today to see if it helps since it only started a few days ago.
My battery seems to be okay but my charge port when I place the cable in it doesn't feel like it fits snugly it almost has a slight wobble to it. Have you guys been noticing that as well?
I've actually been experiencing this as well for a week, I called up Verizon and they shipped me a new phone. So far no charge issue anymore on this one.
I have experienced this too
Tested this again this morning. Had the phone charging overnight.
Unplugged it, it showed 100% battery.
Immediately rebooted, and it dropped to 96%.
With a lot of phones, battery stats reset on reboot. Also- the percentage isn't a perfect science. Just let the phone do its thing. Run the battery down and recharge it. No need to reboot the thing every day.
The battery has been great for me. I use my phone extensively throughout the day, maybe 3-5 hours on time, I always make a day of use without needing to plug in. I had a light use day yesterday, and had 30% left @ 11pm, after pulling off charge the night before @ 11:30pm.
Pleased to announce that (in my case at least) doing a full cycle reset the fuel gauge and it is now working properly. I've never seen a device come with a miscalibrated fuel gauge from the factory, so that was odd. I usually keep my li-ion powered devices between 80% and 30% SoC(state of charge) to reduce cell degradation so we'll see if the fuel gauge becomes uncalibrated over time (which would be somewhat unusual) or if this was simply a software fluke.
Yea I have noticed that in my case, my phone says 100% on the charger so I will restart the phone while still plugged up and once it's booted back up it says 98% so it lost 2% while hooked up to the charger lol. Doesn't seem to affect the battery life. I'm still able to get 5 hrs of screen on time but I will try to kill it completely and charge fully today and see if it fixes it.
This morning I didn't do the restart and didn't use the phone or even turn my screen on and within fifteen minutes I turned it on to 98 % remaining.
