battery problem

Hello guys, I have a Samsung Galaxy Note 4 (N910u) , I reset it a week ago and I am starting to have issues. The phone will not charger more than 70% (fast charger connected) even after 2 hours of uninterrupted charging. When I turn off the phone and charge it still shows 70% but when I remove the battery and plug it in again then the phone shows 100% charged and I am good for another day until this problems repeats. Please help if this is a hardware issue or an issue with software or battery calibration and suggest any methods to resolve it.
Used to happend to me also, but my problem was an kernel issue... So all I did was flashed a different kernel... Also I'm using custom rom btw

Step 1: Buy a new battery (Anker, PowerBear, or genuine Samsung direct from Samsung or carrier)
Step 2: If problem persists, come back and ask again

hi my friend
when you flashed a different kernel the problem sloved or no
and what the best kernel i can flash it to slove this problem
thanks alot
I'm on nemesis 3.7 rom with H-vitamin 2 kernel
You didn't answer the whole questIon, Dorian...did it fix the issue?
Yes I already stated that it fixed my issue in first post
thanks alot my friend
iam install the Kernel you say it and my battery now perfect
Nemesisroms 3.7 fails
I installed that rom but I have had problems.
1. I can not calibrate the fingerprint lock I tried it a thousand times and I finish the steps and when I try it does not work.
2. 3 days ago the phone when I will use it after the inactivity of the night the lock screen turns on but does not recognize the touch. Step to remove the battery and to place it and to turn it on it works well.:Rodar los ojos
I don't think nemesis refined is meant for ur phone model... You could try a different rom that is for N910u, I'm using a N910h... So two different models.... You could also try a new battery and see if problem goes away
Can one of these extended battery kernels be flashed with a stock ROM? My phone is really turning into a laggy POS, I wanna do a custom ROM that's faster and minimalized but I'm worried what ROM can be flashed with what kernel since I haven't felt the need to flash or bake my own ROM in like 3 years since getting my first Note 2...this 4 is a step forwards and backwards.

Another strange battery thread

Hey,
yes i know: another battery thread. But tbh i havn't seen a thread with a similar problem description so far. Im using a Note 3 SM-9005
After my Note3 got super slow with normal samsung rom, i decided to flash it and install LineageOS 14.X. It works amazing! Feelt like a super new phone to me. Just some problems with rotation but i could life with that. One year later my battery started to drain faster. But a while after that i could fully charge my phone, watch some YT videos (like 20min overall) and then the phone just goes off. Its super hot near camera (processor i guess?) after turning it on again it was at 1%. 1 Month ago i tried to finaly fix it by flashing to LineageOS 15.X (Android 8.1) but the problem is still the same. And now its not just videos, if the phone screen is on for more then 20min it will turn off (even if it says 50%)
But not enough.
- After shutting down automaticly, it start itself again and shutdown again and so on. Until i plugin a charger then it stops doing it (or if i remove the battery).
- If im just listining to music it works fine (no screen on time), but while listining music in freezes for 1 up to 3 seccends (on avg every 10s one "freeze")
- It can happen after 5min of usage after charging it to 100% or i can listin to music for over 70min, than can have it in my pocket for 9 hrs, can hear music again for 70min and it still works (all of that with less to none SOT)
I havnt tried so much tbh, cuz i always thought it is a battery problem. But the new battery I got 2 days ago still has the exact same problem. I've read something about save mode and I booted it in save mode and the phone didnt get hot (not even warm!) with 20min SOT browsing (had no time to test it more). But the only apps that I have installed are Spotify, Firefox, WhatsApp and the Blizzard Auth.
Now i tested using a calibrate battery app (my phone isnt rooted but the app said it worked) and now im charging it up to 100% again to test it. But I dont think it worked.
Anyone here with more ideas I could try?
One full wipe and install stock rom .
Charge battery and test over two weeks .
Calibration app NO thats fake it does not and cannot calibrate a battery ( see multiple posts )
Its just the usual battery question and a search answers your question .
How long have you been using that battery? Get a new battery and your problem is solved.
I had similar problems with battery charging to 100% and suddenly going down to 50% and suddenly switching off. Changed battery and all was well again.

I just bought a new battery. TBH it defenetly cant be a good one for that cheap price. But I just flashed back to Stock Rom. With the old battery same problem, but with the new one it works good so far. nearly all bugs that came up the last few month are gone. While setting it up, the phone got really hot (it had to work pritty hard i guess to update everything). This is why JJEgan mentioned to use it for atleast a week i guess.
But an important question: is it possible to flash back to a new version again after like a week? Or am i now forced to use this stone age version of Android. (I guess all samsung apps can be removed if i decied to root the phone)

Battery draining strange on J530F, cell standby and device idle

Hi guys, I am using a j5 2017 but it.s very strange battery drains quite fast in comparison with the old phone. I see strange drain at Cell standby and device idle. I will post some photos, I don.t understand why it drains battery for staying idle. Thanks very much, help is appreciated. Cheers.
PS: j5 is brand new, 1day old... Is this hardware failure? Although i.ve read others are complaining same problem.

Screenshots are here
That's normal man. 48% of screen because you use phone and 12% cell phone is about one longer call. It holds about day so it's okay. If you want to push it longer just root it and install custom rom + grenify
Thanks for answer
Hi folks,I am using samsung j5-00f model.
I am facing the following problems
1.mobile not charging (although it shows charging)
2.As I was saying "It shows charging".. it behaves strange.. it controls iself
...now as I remove/unplug the cable .. it still behaves strange(controls itself)...( untill I restart the device)
3.I have formatted the mobile... yet not charging
4.I have tested with a new battery ( yet it just shows charging but it doesn't) .. confirms that battery works good
5.tried different cables and chargers ( includuing original and trubo )
someone please help me ... I recently have had my mobile motherboard changed ... so I am kinda worried if that
happens again .... ( please let me know how far would this issue cost go if I submit it to a service centre...
do I really have to change its motherboard or might it just get fixed by changing the connector or port or ic
something like that..) ... additionally,using an extenal battery charger I came to know that the battery is working
fine...
update : its been a month and the service center guy keeps postponing ... says ic is not available
please help me ... Thanks in advance...

Galaxy S7 edge heavy battery drain problem

Hi
I swithched from my old galaxy j7 2016 on nougat to a used s7 edge. Now my battery drains wery fast even if my phone is on medinum power saving mode and i have my screen turned off and just listening to Spotify.
My school break is almost over and i dont know if my phone s battery will last until i come home. Before when i went to school at 6.00 AM and came home 3.00PM and i still had 45-60% of battery left and now i dont know if i will even have 15% on charge when i ll come home. I lose my battery charge fast when phone is in sleep mode. I tried a factory reset and it helped a bit but i still lose battery fast. I think its a software problem and i need a new ROM. Im currently on full stock recovery and stock 8.0 oreo rom. Does anyone know any good battery life ROMs. Maybe i ll go to a store and ask if they can help me but my phone just lost my warranty last month, but they ll probably just offer me a new battery replacement and i think that wont solve my problem. Help me please:crying:

Install custom ROM...i suggest you to install BatMan ROM v1.5
I have created a video on youtube (just search for "26 days standby time")
if you follow those steps...your battery can last for upto 26 days and battery will drain way too slowly
will definitely work if you're not a fan of social media...Read description fully (if you have never rooted your phone)

Random shutdows

Hi, i am experiencing a problem on my Note 4, i've had it since it was new and i recently changed the battery for a new genuine one. So my problem is my note 4 dies at 30-50percent battery life and when it dies i have to take out the battery to boot it, it boots up normally but using apps like messenger or generally anything expect leaving the phone untouched. But when i insert my charger i dont get this problem.
I also thought that it was a faulty battery but it isnt the case. I also tried *#0228# but that also didnt help,used WakeLock same problem, reinstalled my OS same problem. Please help me.
bump?
