My N4 started to have battery issues after the kitkat update lasting no longer than 6 hours even turned off. It also started to take longer to charge and gradually this got worse and now all I get is a red light when plugged in but I can't turn it on now.
I guess my battery is stuffed, but could it be that the upgrade did this or (I hope) it was just a coincidence.
I've ordered a new battery and tools but I would appreciate your thoughts on this.

It has been written that the battery shouldn't be run down past 15%. I don't know this for a fact, but that could be one of the issues. Another issue would be an app that is constantly running, but there's no way to find out if you can't boot the phone.
As far as the upgrade is concerned, it's iffy at best because a lot of people have upgraded with no problems.

Hi everyone!
I got a Note 4 a few days ago and it has battery issues.
I got it second hand online from a guy I don't know. I'm from Romania, I think the phone is from the UK, it's Verizon branded. The model is SM-N910V and the Android version is 6.0.1. It's not rooted. I noticed this V version isn't very common.
The battery that came with it was pretty poor, it would drain in a few hours with minimal usage and the worst problem is the phone would suddenly shut down at about 30-35% battery life. Then it would go into a booting loop, without being able to actually boot until I plugged it in.
I bought a new genuine battery from a popular online store here (F64), battery life is better, but still with just wifi, it went to 50% in about 2 hours of browsing. Without wifi or data (very little), it lasted for a day and a half. But the phone suddenly shut down at 8% battery life, again going into a booting loop, without being able to actually boot until I plugged it in. I'd also like to mention, when the new battery came, it only had 4% battery life left (I heard they should come about half charged, is that true?) and also there were a few reviews from people who had to try multiple batteries from this store until they got lucky with a good one. Both the old and the new batteries look identical, I don't see any signs of counterfeit.
Should I return the battery and try a new one? Is there a chance there's something wrong with the device itself?
Thank you very much!
Common problem.

My real fear is if there's something wrong with the device, because I can't return it.

Return the battery.
The seller store the battery in a very poor way.
Lithium should be kept at around 40% charged if you store it for a long time (more than 1 month)
I have 5 batteries with me, 3 of them are considered broken (70 - 60% left)
The last 2 are still in very good condition, around 98 - 99%
About your device, you will need around a few days of charge cycle with a good battery.

Thanks for your answer. I didn't know batteries for this phone are so problematic.
I just charged it to 100% slowly from my PC, will use it normally and see how much the battery lasts and if it shuts down again. As I went through forums, some people say I need to do battery calibration. If it's still bad, I'll return it.
Thanks again!
Try to get a battery direct from Samsung. Failing that buy a PowerBear or Anker. Do a factory reset and calibrate your battery by fully charging it, then running it down to 0% (if it shuts down, keep turning back on until it won't turn on). Then charge fully back to 100% again - DO NOT USE FAST CHARGE.

I will look for a store somewhere. I don't think I can find those two brands here.
I did a factory reset when I bought it a few days ago, but that was with the old battery. Will do the factory reset after I drain it to 0% later today.
I don't have a 'fast charge' charger, and I have it disabled in settings.
Thank you for your response!

What I said before is for all phone that uses Lithium Battery.
Lithium Battery must be kept in a storage at around 40 - 80% charged & must avoid hot places if you don't use it for a long time.
Draining Lithium Battery to 0% will deteriorate the battery faster so it's a big NO.
Calibration is done on the phone not the battery.
Delete "batterystats.bin" to calibrate the battery gauge.
Calibration is useless if the battery is bad (you received it at 0% it means that the storage condition is bad thus the battery is bad.
Charging from PC is a BIG NO as USB port on PC only provide around 500mAh & usually it's unstable.
The charging rate is too low & it could deteriorate the battery faster too.
And the last....I think factory reset doesn't necessary reset the batterystats.bin, so you have to delete it manually if you are rooted or follow this link if you are not rooted.

I had a similar problems, and I have received my new battery yesterday which has been charged in 51% so I drained it to 1%-0% without unexpected shutting downs, I have charged it again and so far it seems to be ok

Hi, I didn't return the new battery after all, I think it 'calibrated' itself after the first charge. Also it goes from 100% to 1% and shuts down properly now.
I did two tests on full battery:
- barely using it, no wifi, data etc, just a few short calls (probably 30 mins of OST) and it lasted almost 6 days
- stress test, wifi and data on, gps with maps and waze on, maximum brightness and and a very long youtube video playing constantly (screen on) and it lasted about 5 hours and 30 mins
In normal use it lasts me about 2 days, but it slightly worries me that if I keep mobile data on all the time it only lasts until the end of the first day.
Would this be considered a good battery life for the Note4?
Thanks to everyone for replying and helping!!
Hey guys, How you all doing ?
First of all, I recently got in hands a Nexus 6p! Bought It used (8 months of use), and its perfect, everything os ok.
Then, I rooted It and now i'm using the Android O ROM, with franco kernel.
But, I've been noticed that the battery sometimes drains 2%-3% too quickly. And yesterday my phone shutdown at 18%!
I was experiencing the 2-3% drain on 7.1.2, but not the shutdown.
I dont get that bad SOT, like 3h-4:30 is still a thing for me.
What do you guys think ? Is It bad battery or software related problem ?
Should I consider doing this trick and go back to Android N ? https://www.google.com.br/amp/s/for...-6p/help/nougat-battery-bug-fix-t3559250/amp/
Here is one print from my screen on time and accubattery.

First of all, going "back" to anything is not going to help you. Android 8.0 is not the issue, it may be a degraded battery, especially if you are having early shutdowns. Please open the Health page (Saúde) and post it. That is where you will find your estimated battery capacity relative to a new battery. You should have a few full charges before this percentage stabilizes. Try draining it as low as you can go (or when it shuts off), and then let the phone charge fully until Accubattery tells you your phone is fully charged NOT the phone reporting 100%. It's common for the phone to continue charging 45-60 minutes beyond the phone reporting 100% and you need to keep it on the charger until completely full to get an accurate capacity estimate. Hope this helps. Boa sorte!
Okay. I went back to 7.1.2, early shutdowns got resolved, but the 2℅ drain not.
I followed all the steps of the guide I posted, changed governator, etc..
It have seen to got a little better. Will report back after a few days of usage with accubattery health status.
Thanks!
6P has been shutting down early for a while now, usually like 10% or less which never really bothered me. Battery life seemed decent, but I never really tracked it.
Last week it started going off at 15-30% at times. But it can be random. Might go below 10% one time, next shuts off at 30%. This was on a prior version of Pure Nexus. So I tried updating to the latest build. First charge it shut down at 40%. Same crap tho, random shut off times. Today it shut down at 48%. By shut down, I mean it just suddenly gives the low battery warning, reports 0% and turns off. Many times I can restart the phone, and it will say like 1-3%, and let me use it for a while before turning off again. This most recent one at the 48% shutdown, I restarted it, showed 1%, used it for a while before it turned off again. Restarted, now shows 18%.
Wtf? Is this just a charge level reporting issue? Tried battery repair/calibration apps/techniques with no success. Nothing looks bad with regards to apps/services draining the battery. I tried accubattery and says I'm at 70% health. Don't even get 2 hours of SOT. Have a replacement battery in the mail. Think this will solve the issues?
It's known issue with some factory battery's for some reason the phone is thinking the battery is low and shutting down even though it's reporting let's say 50%. I didn't have this issue until I bought a cheap replacement would shut down at random percentages especially when opening something power hungry like camera. The only thing you can do is get a replacement and change or send it in to get changed. If you replace it yourself I suggest testing the battery before you put the phone back together. I think the 6p is a great phone and worth it to replace the battery. That just my opinion best of luck. ?

@ 70% your battery has been toast for quite a while. This degradation doesn't happen overnight. If you did your research and purchased one of the "good" replacement batteries from a known good vendor then, yes it will likely completely solve your problem. If you just bought a random battery from Ebay or BFE, then you may have another dud on your hands. Suggest testing the new battery with Accubattery before sealing it back up. Best of luck.

Interesting. Did notice a couple of the times it shut down, and it was this last time at 48% as well, was when opening a power hungry game. And yes I agree the 6p is still awesome today, by far the longest I've had a phone. Considered getting the Pixel 2 XL, but it's a waste of money to me if I can get the 6P working well again.

Hmm, yeah I grabbed one off ebay. Had over 500 sold though, so hopefully not too terrible, but I will test.
I think it has really degraded in the last ~6 months. Possibly from numerous partial charges? Got a new job in April, and I'm often traveling to different sites only 10-15 minutes apart. During this time plug it into my car for Android Auto.
Thanks for the help guys!
In the same boat (But I have a solution for me)
2 weeks ago I upgraded from a beaten GS6 Edge and I am quite fond of my new phone. However I started experiencing this issue, ignored it for the first week since my S6 at 100% battery would die in an hour or two, if I'm lucky. Then the battery problem became an interest to me. I had read a lot of threads on the issue, some saying its a hardware problem, and some saying just a software bug that hasn't (or can't) be fixed. SOOOO at this point I said screw it and just accepted my phone battery as it is. Installed Dirty Unicorns Rom, messed with settings, and boom a breakthrough (I think). DU has a feature called smart pixels in which to save battery life turns off a percentage of the pixels. Wasn't to fond of this at first, but in order to make my 60 - 70 percent battery last i set it to the lowest setting. Every since then I have had maybe one random shutdown, it's only been a week and a lot could change but for me its working pretty well.
Sidenote: I found that not using camera apps, nor Google assistant had also prevented random shutdowns (this helped me with smart pixels enabled and disabled, if you wanna give it ago on stock)
Hello guys. I am experiencing random shutting downs on my phone too. I bought it in January 2017.
What I have observed and today was confirmed is that I have these unexpected shutting down when I charge the phone with fast charge. Today my phone was at 60% and shut down. When I plugged my phone on the charger, the phone was again at 60%!!! How was it possible? I think the problem might be the battery or the internal controller of the charging system...
Ok so my phone is the 2017u, running currently the latest LOS16 but this shutdown has happened on 15.1 unnoficials and official.
Is this battery crapping out on me finally as when I was using my accubattery it reported around 72%.
I have a replacement Cameron Sino to fit but since that in itself could be over a year old (new at least) I don't hold out much hope it's not down to 90% just through age.
Cheers

72% should be decent, although not great. Calibrate your battery.
Calibration:
Drain to 0%, boot phone drain to 0% again.
Charge to 100% without booting if possible. Otherwise charge while in TWRP.
Unplug
Boot phone, then charge to 100%, unplug, reboot, charge again to 100%, repeat until you have 100% after a reboot while unplugged.
Drain to 0% without charging.
Boot phone and charge to 100% while booted.
Then reset Accubattery, do two cycles from 100% to 0% then charging to 100% while booted, no partial charging. Then run normal usage for a week, see if it reports anything different. If your capacity is around 2000mah, you might want to consider replacing it.
Cheers and have done that cycle before for calibration. Does flashing ROMs throw out the calibration as generally always seem to bugger up my phone every couple weeks flashing something that breaks it or doesn't work.
Will do it when I refit my new battery. I happy to burn this battery out this side of Xmas as wanting it to donor its board for a battery mod I have planned anyways.
Was just wondering if it's likely to be that my battery is fooked that's all. It seems to shutdown to dfu mode and then when plugged in it automatically reboots and shows 30%.

If your phone is going into dfu and the battery issue is occurring afterwards. It might not be the battery. It wouldn't hurt to get on a more stable ROM that doesn't dfu, do the calibration again and retest with Accubattery.
I think LOS16 is stable enough. It seems to be at least.
If the battery is below 50 % then it sometimes dfu's if I ask to much of it when the ambient temperature is cold so the actual phone is cold to touch or if I feel heat of the phone around 10 o'clock of fingerprint scanner.
Typical example of cold shutdown is could be speaking to wife on WhatsApp back in Canada and boom it's gone and won't reboot until I plug it in.
Sometimes when Ive tried to use the camera or do moving files and it's warm wherever I am it will shutdown also.

Well you're not the only one who has reported dfus with the latest Los16 builds. So as I said, you may want to make sure it isn't the ROM first. Try testing your battery out on DotOS 2.5, just to be sure, as there haven't been any dfus reported there. I know this would mean clean flashing and starting fresh for a few days, but you can restore your LOS backup as soon as you find that you still have the battery issue with DotOS.
Honestly though, from your latest description, it sounds to be the battery.
Are you using another kernel, like Schwifty?
I've played about with schwifty 4, 5.4, 5.5, 5.8 and 5.10 but reverted back to LOS 16 kernal for now. When the next stable schwifty comes out I might flash that though I'm feeling again this side of Xmas it's not a problem.
My biggest problem is I am moving back to Toronto next year before the spring and I can't be having my phone dfu'in on me if it's too cold hence my asking now to try to work out whether it's the battery or not.
Is there anything I can run after a shutdown to report stuff like a logcat or something ??
Edit
Also it takes an hour to charge my phone to 100% from about 87% which makes me feel the battery is just done now. Remember the same happening on my old nexus 6p and nexus 5 before that.
And if it does get up to 100 it drops charge quite quickly until about 80% then it seems to normalise after into a reasonable rate of loss depending what I'm doing etc.
The phone in TWRP only charged to 94% and had been there for 20 minutes, basically the time it took for my breakfast to come and to be consumed at my local wetherspoons (Brit reference)

Oh wow, yeah, all indicators of a bad battery. I wish i could recommend a good seller, but the one i bought one from gave me a battery with only 80% health. I got 50% refund back, since they didn't want to do an exchange. Still haven't decided if it's worth getting another one. I'm pretty content with 6 hours sot.

Wish I could get 6hours sot. It's ok. I hope my Cameron Sino for the grand x4 or whatever it is will be fine. I am going to hack my back out soon and use my dead battery board to solder in 2 replacement 3000mah or whatever fits batteries.
My Cameron Sino wasn't expensive and brand new so I hope it's in good shape. Either way 2 new lipos from eBay and a small Dremel will do the job haha
Replaced my battery this week with a Cameron sino new from eBay here in the UK. Massive difference to battery life and now the phone is lasting more akin to what I expect from an 820 powered phone.
I'm running
09/18 los16
Schwifty v5 stable
Gms magisk.
Had a nice flat line last night when I was in bed.

i have same problems here so now and then,also happens on older roms.
also weird battery drains and accu % on statusbar.
Some people claimed my battery is downgraded etc,but at this point i think its caused due the burn in display stuff (when your phone is hot and decide to change roms)
i think replacing your battery doesnt solve it
