S7 Edge Battery Drain after replacing - Samsung Galaxy S7 Edge Questions and Answers

Hello.
I replaced my S7E battery a week ago since my old one had 960 discharge cycles.
After replacing the battery and booting it up my phone freeze and rebooted. Idk if thats normal or not
One thing i noticed is that the drain is the same as before! A recently manufactured battery performs the same with my old 2016 battery. I heard about clearing battery discharge cycles to fix this problem. Do you guys confirm? I'm running latest update.
I dont wanna root since i use samsung health and many other features but i'll have to do it if its neccesary
Any help would be appreciated!

[Q] Is the battery gone or miscalibrated?

hello everyone, I'm a new note owner, I bought it used and I think it has two years on it, but it is in great shape. I noticed however, that the battery life isn't that amazing as people have told me, this coming from a Galaxy alpha user. I will leave screenshots of today's battery life and I think it isn't that amazing what it got
I've heard about battery miscalibration, is this really a thing? I can try and calibrated but I need to root it, & I wasn't really looking forward to reading it, since its lollipop on stock rom.
The screenshots are bellow of screen on time and total time, you can see that it's not consistent and I charge my phone two times a day.

I'm using lollipop official rom flashed on Odin via download mode, yes the rom is compatible with my country's frequencies so there's not really a problem there.
I notice however that the battery sort of goes down faster sometimes more than others, sometimes even going as far as draining 10% simply being on stand-by with LTE enabled for 2 hours in my pocket when I'm in class.
Is this normal behavior?
I don't think there is any such thing called miscalibration, I mean I am not sure, but well.
If your phone is 2 years old, then I think the battery has seen its life, time to get a new one mate.
Battery recalibrates itself .
However as the battery is old then Drain the battery to 5% power off charge fully unplug wait one hour top up charge and use .
Next step is new battery Anker brand is good .
Wiping battery stats/ supposed calibration has nothing to do with battery calibration and will make no difference .
Lithium-ion batteries last about 300-500 charging cycles, after that the risk of it dying increases exponentially. Some last 5 years, some 1. It depends on usage and environmental factors.
There is no such thing as recalibrating a modern lithium ion battery. It doesn't have a memory.
New battery costs about 20 quid, it should solve the problem.
Also, did you do a reset after the update? Updates can cause battery drain too, quite often.

No, I did not do a reset after the update. But I noticed this before updating to lollipop, I had to do some running around before I got home the day I bought it, and it was running KitKat 4.4. I got it with 93% of battery, walked home for a bit and was down to 65, went to the shopping and back, got home with 40 to 35%. (I bought the phone at around 5 pm and finally got home after going to the mall at around 8pm)

Then it's the battery, most likely.

Poor batter life

I changed from Note 3 to s 6 edge plus recently
The battery drops 5% per hour overnight when not in use. If I go to bed with less than 40% battery at night I am sure to wake up with my phone switched off in the morning.
When in use with screen on, the battery drips one percent every two minutes. This is the worst battery life I have ever seen in a phone. I was a long loyal customer of samsung and this is my last samsung phone ever.
Extremely disappointed
Please post your battery stats ? so we can have a better understanding of your problem. I suggest you install 'Doze' which should stop unnecessary apps from connecting to the internet and causing your phone to awake from deep sleep.
Dear Akbar 11
Heres the battery stats....is it normal?
I had the same issue, and as far as I managed to find out, it is a bug in Samsung's kernel. Flashing Arter97 kernel solved the issue for, but do post battery stats from SmartManager. If it says 'Android' or 'Android OS', then you have the same problem many of us do.
I don't think it's a kernel problem. My android OS is very low 4%. Like zoolok said post your battery stats from settings, battery, battery usage
I have the same problem. Battery was great before I flash custom rom. After going back to stock I have big battery draining. I must stay on custom rom. With Audax rom and Skyhigh kernel i have great battery life.
You have either messed up something big or you have an app in the background that is eating up your battery like no tomorrow.
And the reason i say that is because i recently got this battery life on my Galaxy S6 edge+.
And this was taken 2 days ago.
Here i use the CRISSCROSS ROM, AudaxPro Kernel, Greeinify and Samsung's own 'Appoptimizing' feature (same as Doze in Android 6.0).
So my battery life is pretty awesome.
i have problem whit battery lose 25% when i sleep
This is a usual day with s6 edge plus
Any help?

i have this problem battery ... if u fixed it tell me how?
Well I was expecting Google Play Services to be eating your battery (which is quite common) but it looks like your Andriod OS is eating the most battery. I would uninstall Facebook and use the web version it always helps with the ram and battery furthermore, turn off location if you are not using it and check accounts which are being synced. These are the only tips I can give you as I have never seen Android OS drain so much battery.
Since a few days Google Play Store is eating up my battery: I go to sleep with 100% batt and wake up with 50%, if I check batt stats on top I have play store at 45%, with 5h active a d 2h of CPU.
Follows Android system at 5%.
Going crazy why...

You've charged your phone 4 times during that day. I can't see what's the interesting part here.

High overnight battery drain while on airplane mode?

I turn my phone on airplane mode at night and the last few nights I did this, I experienced 0-1% battery drain overnight, which was also pretty much in line with what I saw for my old S6. Last night, however, my battery dropped 3% overnight while on airplane mode. In GSam, it says most of the battery use was due to Kernel, then followed by Android System.
This can't be normal? Considering my S6 had a 2550 mAh battery and the S7 edge has a 3600 mAh battery, the S6 would have been using less than 25.5 mAh overnight while the s7 edge was using up to 108 mAh overnight. Considering that Marshmallow has doze, I'm really not sure what could have been using up this much battery!
Do any of you guys have any possible insight into this?
Anyone? I've been checking battery usage over the last few nights and it seems to drop about 3% every night in airplane mode.
There is a leak somewhere within the system apps.

Thanks for the response. Is this a known issue that's happening to many or am I one of few?

It's a known issue happening to many people with the US version of the phone. The one with the Snapdragon CPU.
Found this thread while searching for a solution regarding my Moto G (2nd), because I'm facing exact the same problems. I have NO root (everything stock), and lately I hoped the upgrade from L to M would solve the problem, but yesterday it was back again. The continous battery drain started somewhere at the late afternoon, and didn't even stop after switching off everything you can (inlcuding autosync) before going to bed. Very annoying, though the first days after the upgrade looked promising. This bug seems to be a general problem in Android, and for me it started last year with Lollipop.

A510 Battery Issues

Hey guys,
My A510FD has been suffering battery issues for a long time but it's getting worst nowadays.
100% charge used to give around 9 hours of screen on time but after some time the battery starts dropping from 20% to 0% in matter of seconds.
Nowadays, it drops to 0% from 30% and when charging it only takes few minutes to go from 80-100%.
I think it's because the battery capacity is getting lesser. Anyone else has this issue with their A510? I've replace a battery at Samsung center around 10 months ago and same problem happened to both batteries.
Thanks.
Same issue

What ROM are you using ?
Because some custom rom are eating battery.
The best battery is often on first version (Lollipop downgrade)

Ok, maybe you should downgrade to 6.0 or 5.0 (5.0 is the best), i'm having some battery draining on 7.0 TW
Also you should try to use some hibernation apps like Greenify

Battery Issues/Not discharging to 0%/terrible life

VS995, Rooted, been running WETA since last January.
------------
About 2 months ago I noticed whenever my phone got to 15% battery left when I plugged it in it would reboot. I ignored the issue for a while because I rarely let it get that low.
Recently though I notice my battery life getting very bad. Insanely bad. Not even 2 hours of SOT, dying in 3 hours just using hotspot with no SOT. Losing 10% in a few minutes of active use sometimes.
So I tried some battery calibration apps, tried recharging to 100% and draining again. Tried wiping battery stats. Tried different ROMS.
I flashed desolation ROM tonight and the battery life seems to be really good on it but it ended up shutting off at 24% left.
Battery apps say my battery is in good health, but I'm wondering if the battery itself is bad? Any tips or advice or help of any kind is appreciated. Thanks

I just wanted to make sure because I've never experienced this issue before. I even hand my smartphones down to my mother and they tend to get over 2 years of use and I've never had to buy new batteries. Thanks for the feedback
If it drops from 24% to 0 then im pretty sure its a damaged battery try it ypu can buy it for less than 20 dollars on ebay
If it drops gradually in standby you could have also a battery drain bug but this is not the case here
