Okay so I have this phone for over 3 years now as my daily phone and the battery started deteriorating fast, up to where I will only get between 1h - 2h SOT (phone was always on stock firmware and not rooted).
So yesterday I flashed Noble Nougat Rom 5.1 with Kiboi kernel.
This morning I installed all apps again and after the battery died, I plugged it in with Accubattery running.
As I write this, Accubattery says 2724mah has been charged in 1h50min and it is 90% charged. Will post a screenshot of fully charged stats.
Battery design capacity is only 2550mah. Is it possible that Samsung limits the phone not to use full capacity of battery and Kibio kernel "opens up" the bottleneck? Are the stats wrong? Does Kiboi kernel mess up charging current recognised by Accubattery? Whatever is happening is beyond my understanding and reasoning.
I ordered a S7 batter to replace the "bad" stock battery, but now the stock battery looks not so bad after all. The proof is in the pudding, however. Will see how this charge holds up and let you know.
Screenshots
Had to unplug phone at 94% to take a call. Screenshots below.

Could be a bug.
Or maybe someone put an S7 Edge battery in your phone before you got it.

Between those 2 options, I'd say it is a bug, because I bought this phone new, unless Samsung put it in there for me.
Okay so I resolved that it is some kind of bug causing Accubattery not to be accurate. After 18h light use I only managed to get 2h30 SOT of this charge. Battery still sucks so now waiting for S7 battery to arrive.
2nd Charge did much better, 3h45 SOT. It felt like the battery will never die (i want to have 2 - 3 full charge/discharge cycles with new rom and kernel).
I think the new rom and kernel is a good match for the battery because I notice a significant change. Usually the battery dropped about 3 - 5% and hour while in standby, now the drop is down to about 1% per hour.
For all of you struggling with poor battery life, I suggest to flash Noble Nougat Experience 5.1 with Kiboi kernel.

Hi,
You should use your battery for 3 or 4 cycles (charge/discharge) before judging it.
Yes above post is correct. Please cycle 3-5 times before judge. I just received a. New mugen 3500mah battery
It's recommended to cycle 4-5 times before it reaches full capacity. I'm on first cycle. So far a hour of use still at 100%.but it won't be to full capacities until its cycled at least 4 times.also I read not to drain to zero percent before next cycle. Hope this helps out.also you can get a long lasting battery if issues still persist. Personally I finally broke down and got a mugen 3500 mah for my device. The back cover is pretty ugly but so far first cycle battery is amazing! That's what matters to me anyway. Phone may look a bit pregnant but great battery life is the trade off . So far its worth every penny. I was tired of having battery issues. If you do decide to purchase one. Purchase from mugen site. Also follow instructions before use device must be charged 12 hours even if showing 100% also instructions recommend never discharging to zero before next cycle of 12 hours . I hope this helps.
sent from HTC sensation, soff, 3.33 firmware, viper Rom, sense 4.1, mugen battery. please press thanks if I helped in anyway.
I'm using Cyanogenmod 11 M5 on a D820 32GB. Lately I've noticed that idle battery life is not as it should be; I got frustrated enough last night that I wiped everything and left it sitting. Battery started at 82% and dropped to 63% with about 15min of SOT::

This doesn't feel right; as I recall from when the phone was new (and as I have seen others talking about), standby time is supposed to be great. Is this normal?
I'm flashing stock right now; I'll see if that helps.

Show us some BBS logs. Most likely CM issue though. More precisely, the CM kernel. But without BBS, it's just speculation.

Okay. I'll try this with stock Android and see what happens. If it's not better, I'll post BBS logs for it too.
I also think it's CM's fault, and if this happens with stock as well, you may have a faulty battery.
I usually get 1 hour SOT/20%, give or take 10 minutes.
I can get this with my usage patterns, obviously this is going to change (for better or worse) depending on how you use and configure your phone.

Awesome as in how long?
At any rate, after totally paving my device the drain seems to be better on M5. Not sure what the issue is/was.
WTF is going on with my battery? I have the S7 Flat snapdragon version (G930v) running the G930u software unrooted which removes all carrier bloat. Screen brightness is set to a little past half way. I have all setting provided by stock software optimized for maximum battery life other than running AOD. I am running a black Wallpaper/Lockscreen/ and an All black theme from the Theme Engine.. Wth hell is going on here. My battery time is looking Rediculous in comparison. Someone help me out here.

I feel asleep around 3am I guess with 89% and woke up just now close to 11. Heres battery over that 8hr period. 5% during that time. Standby drain is not bad it seems. But only 10hrs on 100% is crazy low compared to what some of you guys are getting.
End of Trial:
What can I do to get this increased.?

Is the same problem present with the phones original firmware? What you call bloat may very well be needed adaptions.
Urs is mutch better the what i get, mine drains 40% over night ..
My battery today.
Auto brightness and location on power saving.
Aod off.

When I first got my Note 20 Ultra (Aug of last year) the battery was amazing. Now within the last 2 months is horrible. My phone shows a full charge will last 11 hours and 51m. Just today I was out and about, unplugged at 11am est and by 4pm I was at 41%.
Not sure what has changed. Though Facebook is showing around 10-20% battery usage over the last 7 days which is odd since I'm not using it that much.
Ditch FB* and any social media that's loaded as an app... crapware.
Clear system cache.
Disable all power management.
Now see what's using the battery and if it's appropriate. Go from there.
Install Accubattery to track battery use history.
A well optimized Note should about 7-14%@hr SOT, less than 1%@hr with AOD in tap on mode at night.
After doing all this reevaluate if it's a weak battery or just excessive power usage.
*yeah I know you can't send any FB messages if the app isn't installed... ditch this malware. It's malware by design not coincidence. FB is a menace... learn or get burned.
This is my N10+, the N20U may use slightly more due to variable refresh rate and 5G but should be similar.

Battery aging process.

I figure a on heavily used Note that's fast charged the battery will last 1-2 years.
My last N10+ battery failed around the 1.5 year mark. I'll probably replace now at 1 year intervals.

I am interested in this battery performance? What SOT are you getting? What do you get for battery time the medium power saver mode?
Any screen shots are appreciated.
It's on Friday and I feel like the first 48 hours it was draining pretty quick. I upgraded from the OnePlus 6t and I certainly feel the slower charge.
Waiting for it to fully discharge and then I'm going to give it a full charge and then I will post my battery stats after seeing how long it lasts.
Full charge before bed last night .. and I drove around a bit today with it plugged in for about 30 minutes. Going to bed now at around 50%. Not going to charge until tomorrow.

I am still trying to figure out if I have a battery drain issue. I am getting the same usage as what I did as my A70. After full charge it says it will last around 22 hours. Usage is the same as with my A70, not sure if that is right.

Standby uses about 1% for every two hours for me with Always On Display. That is always my benchmark even for my last Samsung. There's something using battery wildly if it goes too high after some many hours or even within one hour.
A hint there, try rebooting 3 times in an hour or so. My last Samsung had an issue where normally one reboot would fix the battery drain but it would every now and then require two more to fix the drain.
The battery use stats might help you narrow down to something but if not then you have to factory reset or disable or remove stuff. If its with the rom then it gets more difficult.
If you are seeing the 1% standby for even an hour or two then it should be fine there and the drain is only while the screen is on.
You might also be able to spot certain things the the logcat.
Thank you for your reply. I will try to reboot it. I have done a factory reset but it hasn't helped. I will test it for a few days.
I have 9hours Screen On Time on a pixel experience rom.
AOSP does wonders to this device.

You never know. Funny how much reboots fix things that shouldn't need fixing in the first place
