Battery weirdness since last system update. - AT&T Samsung Galaxy Note 4

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%

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....?

Battery & Charging

So I've been having issues with battery life and my charging.
When I woke up this morning my phone was at 1%. I went ahead and played with it till it died. I kept it turned off and let it charge for about 2.5 hours or so. I would think that it would be close to fully charge. The battery charging icon when phone was off made it seem that way, but when I turn my phone on it's only at 40%. I turn it back off and let it charge for another 1.5hr while i'm at the gym. Come home to find that it's only charged up to 46% since then.
This is a brand new, official samsung battery. Came with the Samsung spare battery charger. Similar things have happened with a 2nd spare battery i've bought. None of these issues happened when I was using my original battery though.
Do you think it's the phone or the battery itself? I'm leaning towards phone

Phone was 25% battery, But 50% battery after reboot?

Hey guys, I've had my phone for 4 or so months now and I always charge it while my phone is off and never had any charging/battery issues until today, I decided to charge my phone while it's on and it charged up to 25% and I restarted my phone without removing it from the charger and after it booted back it it's showing 50%, I restarted a few times, tried a cold boot, it's still 50%.
Is this a known issue with this phone? does anyone know what's causing this? I've never had this happen before.
EDIT: After this happened I ran my battery to 0% so I can attempt a battery calibration and when I poped it on the charger it showed my battery was actually 0% and showed a yellow hazard triangle thing (normally it only drops to 1% and there has never been a yellow triangle before)
Sometimes the Android system can incorrectly report a battery charged. I have had it happen to me on my Nexus by about 10%, but have not had it happen to me on my G3. I would not worry about it too much if it only happened to you once. If in continues you to jump around in battery percentage, then I would suggest getting a replacement battery. Keep in mind to try not to leave it charging for very long after reaching 100%, from my experience it can effect a battery's ability to hold a charge if that is done repeatedly. Which means do not leave it charging overnight while you are sleeping. Also I would not suggest running it until 0%, I would imagine a sudden shut down of the Android Operating system is not a healthy thing for it either. Just like it is not good to go up to a computer and just pull the power cord.

Thanks for the input.
I never leave my phone on the charger while I sleep since it only drops 1% while I sleep. My phone actually only goes on the charger like 3 times a month
I know it's not good to fully drain the battery very much, I was just draining it to attempt a battery calibration in the os. And when I do this my phone usually only drops to 1% then dies, but all of a sudden it dropped to 0% this time and showed a big yellow triangle with a big exclamation mark in it
Anyways I reflashed my rom in hopes I can flush the problem out. In 4 months of owning this phone I've never seen this warning before.
This is almost exactly what happened with my old phone (Samsung Captivate Glide). If this continues to happen, it is one of the first signs of the battery failing. But if this is a one time thing, I wouldn't worry about it.
In my case, the battery was going bad. It started going from any % battery, down to 0 instantly, forcing a shutdown. After rebooting, It would show a decent charge (~60% most of the time), but would do the same thing within 5 minutes. At first it only acted up like this once a month, but it became more and more frequent that it happened every day, after using the phone for only 15 minutes. The only fix is to get a replacement battery.

tyvm, This is extremely helpful info to keep in mind. Now that you mention it I have seen the battery kinda swollen up a couple times when it got hot, only ever so slightly but I did notice it.
If my issue persists i'll defnitly try a new battery, thanks for the tip

CM11 battery issues

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.

Battery charge issue...

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.
