Hello!
My phone usually lasted 4 to 6 days on one charge. Suddenly, overnight, the battery went from 100% to 24%!! Couldn't believe it so i charged the phone again fully and as i went to bed the following night, i turned off the phone. In the morning the phone would not power on! Battery was fully drained!!
Did a factory reset and the problem remains.
Any thoughts?
Thanks in advance.

Over night my main battery went completely flat. There was no charge left in it in the morning!!! The phone rebooted itself n the battery was completely flat. Don’t know what happened!! any ideas as to what happened? M foxed!! I charged my phone in the evening completely. this has never happened before..it always has sufficient charge left till the next evening!!
check yr power and backlight options. make sure they're set to conserve battery.
i charged it in the morning.. now it seems to be working fine.. will moniter for a few days n c.. for a minute i thought that my battery went kaput..
I recently purchased a used S4 through Swappa from XDA user @disasp6. When the phone arrived, the battery was fully discharged. I let my wife use the phone a couple of days while hers was being repaired, and she experienced the battery running completely down and needing a recharge before the end of the day after being 100% in the morning. I then turned the phone off and put it aside for over a week and when I tried to turn it on, the battery was dead.
I tried a test, charging the battery to 100% and pulling the battery out of the phone for 24 hours. The battery retained it's charge. It did lose just a little bit of charge in a 24 hour period, but I was able to top it off with about 10 minutes of charging. I then left it in the phone for 24 hours with the phone turned off, and at the end of 24 hours the battery was fully discharged.
I've never seen a problem like this. Any phone I have ever owned has retained it's full charge when turned off. The phone is running safestrap with Goldfinger 9.0 XXUGNK4. It seems to be running normally. I haven't seen any issues with the phone firmware or its operation in the limited time I have been using it.
Does anyone have any idea what the cause of this could be, or how to troubleshoot the issue?

I'd say first thing to do is wipe and start from stock. See if that fixes anything.

I flashed back to stock NJ4, rooted and installed Better Battery Stats. I fully charged the phone and left it unplugged over night. After 8 hours of total inactivity, the battery had discharged from 100% to 60%, and Bettery Battery Stats indicated that the phone was in Deep Sleep 100% of the time since unplugged. There were 0% partial wakelocks of any kind. In my thinking, this verifies that the issue is hardware related. Does anyone have any thoughts on this?
I would think idle drain with 100% Deep Sleep should produce somewhere around 0.5% per hour drain, and certainly less than 1%. I'm not familiar with the S IV so I'm not sure the exact number. Can anyone verify this?
Hi, I'm having a weird problem. Last week I replaced my phone's battery. Everything was going fine till the first charge. The battery percentage isn't showing the right value.
After charging the device all night turned off. Battery shows only 79% of charge. If I let the phone charging turned on, it gets to 100%, but short after drops to 85% and then 79%.
First I thought it was a faulty battery. But I'm using it for a week now, and the device holds a day without a charge, I can even get 3 hours of sot.
I tried fully cicles of charge, to see if it's some kind of calibration, but nothing helps.
Any ideas?
Calibration apps or BBS?

Try battery calibration apps or use Better Battery Stats to find what's doing this!!
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.
I bought a 1 year old note 4,it usually dies at 25% percent,it drops suddenly to 0 %.,after weeks of research i found it is caused by faulty battery so i bought a new battery now it dies at 10% to 0% in seconds and turns off,i flashed a kitkat rom now problem is solved but i want to be on lollipop due to UI changes,can any custom rom solves this? i've tried dr.ketan rom,same issue dies at 10%...

Probably caused by battery calibration. Just use your prior rom from 100% to when it shuts off a couple of times to retrain it.
If you use multiple batteries like I do, you'll never be able to calibrate, and will just have to live with this issue.

Well not entirely true. Ur battery have the chip that tells the system how much left the battery is. I often have those prob. But now is gone. I just charge until 100% let it 10min charged. Then use it until it off. (Really really off.) Like when the battery circuit stop the battery not the phone shutting down. After that charge until 100% and after 100% i let it charge for 1hour to make sure it really 100% . done
Same here after last update. From 10 to 0% in second
+1 here
Thats why I utterly I hate sw updates.
My Galaxy NOTE 4 SM-N910C
Same problem here ,, considering buying a new battery but afraid that the problem isn't from the battery and get the same drop again with the new on
my phone is 1 year old
i had the same problem, so what i did was to flash the Rulinglite ROM for my note 4 910 C. it works fine now.
Hey guys, I got the same problem. Sometimes it drops from 15% to 4% in a few minutes and then from 4% to 1% in another few minutes (without using phone ofc).
Also, when i charge my phone - it shows me 100%, but when i reboot it - i got like 94%. Few minutes later - again 100%. After reboot - 95%.. etc etc etc... (charger is pluged on for all this time)
Do you have this problem?

Same problem here
my problem is that the battery percents are getting lower ery fast..if i make some actions that require more battery and i have 20% of battery, the percent goes to 16 so quickly and then the phone hangs up. I turn it on, it shows lesss battery, then it hangs up again and i need do recharge the battery. I bounght the phone at 2nd hand, i noticed the battery issue since i was testing it, but i love the phone. i am affraid not to be a hardware problem with one of the internal components of the phone, that killed the battery...i tested the battery on Note 3 and i am sure that the battery has a problem. What if i buy a new battery and a malfunctioning component of the phone damages the new battery too?
For me: i will dial *#0228# press quick start and wait till phone lids up connect charger and charge until 100% and then dont unplug first leave it there for 30mins or more and then unplug. ( do not unplug it halfway )
Second i switch off my phone take out battery and wait around 3 mins and then put back in and start charging it to 100% without switching device on, also same thing leave for sometime before unplug when it reaches 100%. you can also switch on after 100% and wait for sometime. ( as booting phone drains battery too )
hope it helps
Bought a new battery still drains at 10percent exactly,thought it's a lollipop issue,but even in MM it exactly shuts off at 10%.
