Whenever I pull my battery out and put it back in, my phone’s battery is drained to 1-2% and weirdly start to rise till 7-8%, even it was fully charged before. Why?

The battery on this phone has been great. I have been charging it only if it is below 20% when I go to sleep. Typically every 2, 3, or even 4 days. Last night it was at the end of its 2nd day of light use and the battery was at 57%. I turned sound off and left it on but not charging. This morning the phone was off. When started I got the critical battery message and it showed 2%. Plugged phone in to charge and then the battery level immediately went to 56%.
Any ideas what could have triggered the phone to think the battery was at 2% and shut down?
Battery screen in settings shows the 56% level too. Shows on for 2 days and 6 hours - screen use 33%, cell standby 20% and the rest looks normal... Except that it shows wifi at only 3% of use. This seems odd as the phone has been on my wifi system more than half of the 2+ days. Shows connected to it now. Does 3% for wifi make sense?
Thanks!

I've not seen that behaviour on my Note 3, but I seen something similar on my Galaxy nexus that turned out to be the micro-USB pin had been slightly bent out of shape, causing the thing to occasionally think it was charging when it wasn't and other weird stuff.
OK - Thanks. That is definitely something different. In my case the phone thought it was at 2% and shut itself off. Then when I powered up the phone, it gave the critical battery warning and said it was at 2%. Then immediately upon plugging in to the charger, it said it was at 56%. I then unplugged the phone and it has been fine since. So the powering off and the 2% warning was in error. Strange. If nobody has seen this behavior before or has any idea why it might do this, I guess I will just think of it as a misfire of some sort and hope it does not happen again.

it seems to be software bug.
Flash Stock ROM or repair it by kies

Try cycling the battery. (drain till it won't come on, charge with the phone turned off, turn on at 100%)
Hello all,
As the title says, I'm having this weird issue with the tablet. The tablet loses a significant amount of battery charge when the device is turned off completely. For example I would charge it to 100% at night then switch it off completely, not just to sleep, I would wake up to about 60% battery left. I'm seriously confused what to do. I have taken this tablet 3 times now to the service centre. They even changed the battery for me but the problem persists.
I've attached a screenshot of the battery stats example. I've turned the device off then when I wake up a few hours after, it was only 57% left.
If the device is on /sleep mode, the battery actually drained normally.
Any help would be appreciate it, otherwise I would have to let this tablet go.:
I've owned my Note 4 since October 2014 and it's been working solidly since. Last Thursday, out of nowhere, I noticed that from a 14% charge, it suddenly dropped to 4%. I immediately scrambled for a charger and charged it back up to 100%. On Friday, I charged my battery normally again. Charging finished at 11 AM but the drain was abnormally high. My phone was warm to the touch and battery was dead in 4 hours. I was using the phone normally throughout that time, 4g on, location services/bt off, screen off for the most part. I ran OS monitor to see whether any app was locking up the CPU, but, as expected, the main CPU users were Android System and Android OS.
On Saturday, I charged the phone to full again, disconnected around 4 pm. Being that I was home, both wifi and 4g were off. Battery discharged normally, and was only down to 30% on Monday morning.
On Monday, I noticed that battery dropped from 21% straight to 11% straight to 4% in a few seconds. The drain from 4 to 3 to 2% was decent (few minutes of screen on time, on viber), then the phone shut off. I tried to charge the battery with the device powered off, but noticed that the phone simply stopped charging at 80%. I thought that was an abnormality. I tried wiping the system and app caches, but the problem persisted and drain still felt pretty fast. Tuesday night, the phone stopped charging at 91%, staying at the same level for 40 minutes before I gave up and unplugged.
My friend had purchased a fake OEM Note 4 battery and allowed me to try the drain/charge process using his battery to troubleshoot. When I first plugged his battery into my phone, the drain was high at about 1 percent per minute. When I tried to charge the battery, the charge level would not go beyond 90%. I switched on safe mode, but the battery did not charge any further either. I felt by then that something was definitely wrong with my phone. When I restarted the phone to get out of safe mode, though, it suddenly started charging again and hit 100%. With regular use, the fake battery gave me 16 hours of power, which I thought was relatively decent. Alas, when I started charging it again, it stopped charging at 77%. Battery Monitor Widget showed 0 mA flowing into the phone at the time, though the battery indicator in the status bar showed the lightning bolt.
I took out the fake battery and put in my original. It is now charging up normally, but I expect charging to stop before I hit 100%.
If anyone could provide possible explanations for what could be going on and/or other troubleshooting tips to try, I would really appreciate it. A factory reset would be my last recourse.
Thank you very much!
EDIT: My battery went all the way up to 100% this time. But it's the same one that got stuck (at 80% then at 91%) twice in the past.
I'm using two different Samsung chargers and different cords, by the way, and blew out the port with air prior to attempting to charge the fake battery that still stopped at 77%.
I had the same issue, took it to Samsung and they replaced the battery, it has been okay since that

Really? I was ready to write off my battery and just buy a replacement, but what was weird was that even the newish fake battery wouldn't charge fully. That's what made me worried that it's my phone that's the problem.
It'd be great if this could be as simple as a battery problem.
Battery Suddenly Shutting Down Before 0% (Possible Solution)
Ok so after a bit of playing around I have seamed to rid of the battery cut off at 15% - 20% and so on.
As I was doing the battery reclab I noticed when I drained the battery and the phone would turn off, then restart the phone it would boot alittle then shut off. Then I'd plug it in with phone Off and the display would show an instant charging percentage of around 5% -10% -15% . I noticed the battery was not discharged to 0%.
What I did was boot into recovery and keept the screen on for as long as it needed till the battery really died and the screen turned off. I was surprised how much battery was left. Depending on your battery. It took me around 30min to die.
After that I then plugged it in to do a full charge with phone off.
Let battery die again boot back to recovery and keep screen on Antill screen shutoff.
Do full charge again.
Antill you see your battery shut off at normal 0%.
I did this twice. You may need to do it more depending on your battery state.
Give it a go. Who knows it may work for you.
Good luck

I had luck doing something similar in TWRP.
My issue is my battery still only reports about 75% or the capacity that it should.
Waiting for my replacement from Google.
I need a good battery in my phone and 75% in a "like new" replacement is not going to cut it.
This is an issue I've noticed in not just one, but many ROMs that I've tried on my G5 Plus.
My phone is almost three years old, and with time, battery backup would gradually decrease, which is normal. But in my case, I've noticed that my phone isn’t displaying my battery’s true percentage at times.
For example: I usually don’t discharge my phone completely down to 0%, but what happens is that when I do it and plug in the charger while the phone is dead, the battery indicator doesn’t show 0%. It has showed 15-20% and even percentages like 52% and 62%. I don’t know what's wrong with my device. I used to think its some kind of ‘reserve charge’ and turns out, its not. After some reading, I came to know that my battery needs calibration. I tried doing it today, and drained my battery down to 0%. And long behold, my battery indicator started charging from 26%, instead of 0%.
Can anyone help me with this? Would be great help. Thanks!
