I found myself seeking threads in these forums about different ROM's and SOT obtained. The results were way different between different users, some claim to get 2.5h SOT some 5h SOT under normal circumstances.
Under normal circumstances I never get more than 3h and I suspected that my worn battery (598 charge cycles according to "Charge Cycle Battery Stats" app) was far from the original 3000mAh.(Thats a manufacturer stat obtained in perfect conditions, real world must be around 2800mAh)
I needed to measure the capacity left in mAh,so I bought a USB ammeter power meter (Keweisi white digits, but you don't need it, I'll explain later).
Using the Power meter, to measure properly you need to avoid thermal loss and power loss when charging:
- Note 5 completely discharged at 1 or 2% battery left.
- Disconnect the Fast charge option in Android.
- From start to finish keep the note 5 Switched off.
- Use an USB low power charger, mine was charging at 0.8A
Results: 1800mah that's far from the 2800mAh(3000mAh) when new.
(Same test I'm getting 2200mAh out of the original 2800mAh on my old Galasy S5 Neo.)
You don't need USB ammeter, Android has a builtin ammeter calculator(estimation).
Today I depleted the battery (2% left) of my note 5 again (Rom based on Android 7.0) and under battery usage I added all the "Computed Power Usage" in mAh giving the next results:
mAh
557 Cell standby (I worked underground today)
333 Screen 2h53m (30% brightness and auto brightness on)
271 Device Idle
221 chrome
203 Android OS
43 Google Play Serv.
39 Androyd System
27 Youtube
20 Yahoo Mail
20 Wi fi
17 com.android.systemui
Total: 1751mAh
This result shows that the phone itself makes a good estimation of mAh juice available in you battery.
As an anecdote I run the same test that Jerryrigeverything in YT with his Note 5(6 month of use): Playing a 2k video in 100% brightness( auto brightness off) with sound and in Flight Mode(not even wifi). He gets 6h20m, I surprisingly get 6h. But those test are only worth to compare Note 5's
Conclusions(my own and humble): Surprising degradation of my battery, specially compared with the results obtained in my S5 Neo. According to "battery university" (a good scientific source of information about Lithium-Ion) I might have shorten the life of my battery abusing of the fast charge mode.

Same here, the problem is that is quiet impossible to find a genuine battery for replacement. All those on amazon and ebay are crap.

That's the next step, find a good provider and compare capacities.
What I know so far is that there's 2 different battery models:
EB-BN920ABE The most common, but most reviews complain about being 4 or 5 mm shorter, ...less volume less capacity.
EB-BN920ABA Difficult to find, It seems the original replacement according to this picture:
https://ae01.alicdn.com/kf/UTB8YQ_yanzIXKJkSafVq6yWgXXa0.jpg The original is the right side one.
I found a Canadian provider who seems serious (free of fantasy marketing) who also ships worldwide, it looks like the original, (or a extremely good copy) I'm going to take the risk and try it:
https://www.ebay.co.uk/itm/OEM-EB-BN920ABA-3000mAh-Replacement-Battery-for-Samsung-Galaxy-Note-5-N920-N920A/401346669803?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

How did it go? Those eBay batteries tend to be pretty bad in my experience.
Finally someone else is concerned about note 5 battery capacity, i replaced mine with an original one in feb 2018 from a nearby samsung service center for $40, i used Accubattery app to measure and compare the battery capacity of the old vs the new battery.
After two years of usage and fast charging enabled in all of charge sessions, the old battery was giving me 76% (2291 mAh) of the original capacity, while the new one is giving me 89% (2675 mAh) right now, the weird thing is that it was giving me 90% right when i purchased it, i dont know if this is normal or not.
As for SOT, the old battery was giving me 2.5 hours on average, with an average of 17 hours of total usage, the new one gives me 3.5 to 4 hours with an average of 20 hours of total usage (disconnect at 100% from charger and drained to 1% or 2%)
Hope you find this post helpful

I'm in the same boat as you. My battery life blows and I am looking for a decent replacement so I don't have to buy a new phone. How did that one work out for you?
After one year use I am now at 3,601 mAh
What's everyone else at?
Although I use Accubattery app
I don't think its estimate of battery health or capacity is particularly accurate.
The app states that it estimates capacity.
It estimates mine as approximately 3600 mAh
Bought Aug 2018
Manufactured 21 Aug 2018
never trust the battery apps for how much % i have on my battery , apple have that but thats way out my x says 93% but still gives me the same screen on time as when i bought it , by unplugging the battery and plugging it back in the iphone now says 100% , with my note 9 i still get over 8 hours screen on time , all these apps on batteries do is count the full battery cycles and deducts the % over time , the best way to check any battery is by your screen on time , if its good then theres nothing to worry about
What did it show from the start? When I first got my phone, it calculated that my capacity was around 3400 mah. I actually managed to change the battery on the warranty and now it says estimated 3800 mah. An improvement, but not really what I was expecting...
3782 here.
Why am I not getting the battery life that you guys have? I'm currently at 62% battery with 2 hours and 58 minutes SOT, no gaming, just light usage. I have the 128GB Global version running Android 10 Beta 5 but even with the latest stable Android 9, I'm still getting similar results. Could this be a hardware problem with my phone? I'm sooo disappointed because I got this phone for the battery life and it just doesn't feel like a 6000 mAh phone. Attached are some screenshots.
On 9 I get ample battery life, also it is a beta, so assuming ymmv
Wow that's bad, light use I get 2 days.
Can't help why though, I'm on Android 9
Although to a certain extent, we even came to doubt that Samsung would update the Galaxy S9 and Note 9 devices with the OneUI 2.1, it is finally here, and it cames with Deep Sleep Apps feature, which will allow to actually suspend all services and processes associated with an app.
This has resulted in a relatively big battery life improvement when the device is on standby with S10 and S20 devices in controlled tests1.
Galaxy S9, S9+ and Note 9 are devices released more than 2 years ago, and surely the battery stamina is not the same as they were in their first months of use. Samsung stats that the batteries used on these devices should keep a decent stamina for 2 years with the average user.
Some people have used their phones with battery care measures1, in order to extend battery life.
So, with the recent release of OneUI 2.1 for Samsung Galaxy Note 9, the battery life with the device in standby is expected to be longer (but not the screen on time), although the magnitude is yet to be determined in the coming days.
This thread is aimed to share our opinions on the subject, as the update becomes available and we can evaluate the battery life.

IOS uses a choise in his battery settings to charge the battery up to 80 % of it's capacity and then charging will stop to improve the battery's durability.
It's known that standing in battery's 20/80% capacity increases its life and durability and doing this you can charge how many times you want because one parzial charge will not be counted as an whole cycle of charge so the battery might last more than 3 years going on like this.
This choice is not implemented in Android even with one UI 2.1 and it's a shame even if the new feature will improve battery's autonomy due to the lower consumption of the apps and even if it's impossible to perfectly be able to stay in it's 20/80 percentage range, there's an app that I found that will avert you when reaching 80 % of its charging capacity so you can disconnect the cable to preserve the battery....

You're right and I keep charging between 30 and 80 but this shouldn't be how the phone charges by default as you said. Many people charge from 15 to 100 and want that extra 40-50% they'll get by doing so. I found that without fast charging it takes 1 hour from 30% to 80% so it's no big deal to look at the clock when you leave the phone on the charger.

Even your right, there are even people that continually from 0%(completely dead) goes to 100% after charging the battery for the whole night... that's why what I said for charging should be a choise (like in IOS) and not a default setting.... strange thing that Android or Samsung didn't consider implementing this choise. Fast charging even worns the battery first... it stresses the battery and it will last less but at least they gave us a choise in using it or not.
Absolutely true! Samsung should have implemented a feature to limit charge at 80%, or implement a Bixby Routine to enable this behavior (for example, when charger is plugged at night)
50% increase in my case. And i used OTA Package to update manually.
From: 4h SoT in 24h
To: 8h SoT in 24/30h
Idle times are impressive.
EDIT: just FYI, i rarely charge up to 100%. So my average case is from 85/90% to 5%. Very rarely do i go for a 100 to 0.
One UI 2.1 improvements are all courtesy of the Deep Sleep feature.
I've added everything i barely use or dont need to create wake-ups on the Deep Sleep list. On the normal sleep list, i have low priority things like Play store, etc. And i make sure i white list everything i need untouched (Messenger, WhatsApp, etc) and also do the same thing on the Memory management. Solid results.
Edit: 100% to 1%. 10h SoT with a 30h cycle. It's like getting better and better.
My tab a 2019 has the 80 percent feature and I do not understand why they wont offer the simple setting actually I do because phones they want you to replace the phone instead of the battery in 2 years. I run my note 9 from however low to 100 every night but only because I dont have the option these newer android 9 then 10 now 2.1 adding more and more apps into the firmware but wont add a simple little feature as this. Also I would like to be able to choose if I want to do ota with my data! But I cant.
For me One UI 2.0 was already worst with about 3 to 3.5 hrs of screen on time. Now with 2.1 i barely get close to 2 hrs of SoT. My note 9 is running stock since i bought it at launch and have never done any factory reset. Only thing i do is wipe the cache after a upgrade.

I've Snapdragon variant, running one ui 2.0. Battery life on my note 9 is phenomenal ?

Bro you need to factory reset and start fresh and if that doesn't help something is wrong with your battery I get 9 SOT all the time with 10 2.0 with android 9 it was about 6 SOT, I haven't received 2.1 yet. I have us unlocked version.

You have a snapdragon variant which is anyway much better than exynos variant (my phone) for battery backup.

Stop saying Exynos is not good for battery life. I can easily get 8h SOT of regular usage on my SM-N960F running OneUI 2.1. Obviously I don't play games like Asphalt 9, etc but I never use power saving modes and never limit myself in order to save battery life. I play 8 Ball Pool when I want to, I watch YouTube for as long as I want to, I browse Instagram and use Samsung Internet Beta when I feel like it. Not once have I ended up in a dire need to recharge when I was outside or when I needed to use the phone. Also the phone charges 50% for 1h (I charge between 30 and 80%) so I just leave it charge while having dinner, watching TV or something like that - when I normally wouldn't use the phone anyway.
On my N9 seems battery life abit improve from previous 2.0. Sammy did great job this time.
Here is my screenshot to prove it.
It takes time to see improvement in your device's battery life after installing OneUI2.1. As the software AI needs to learn all your habits again before any improvement in battery life will occur. This process should take a few weeks
I have been using my brand new Tab S8 5G for 8 days or so. I have AccuBattery installed. The estimated battery capacity has been very low from Day 1. Currently I get:
Battery Health 87%
Estimated Capacity 6759mAh
Design Capacity 7760mAh
Based on 31 sessions 1031% charged for 69688mAh
I understand it takes a few days for AccuBattery to function accurately, but I think it's been enough. The design capacity has been automatically measured and already adjusted to a lower value than what Samsung advertise (8000mAh). I've also installed 3C Battery Monitor app, but the estimate is very similar (3718). I have bought 2 other (non-Samsung) android devices in the past few months, but their estimated capacities are much closer than 100%.
Has anyone expericed the same? Or do you think mine is a bad lemon and should be returned? Any insight would be much appreciated! Cheers.
Are you charging to 100% or just 85% (battery save option). If you charge up only to 85% then it is accurate.
Thanks! That's a very good question. I have used the 85% charging limit option for a couple of days but left it off for the majority of time.
But wouldn't it be the same from AccuBattery's point of view if you used the option or not, as the tab tells the app 85% as 85% not as 100%? (or maybe my assumption is wrong).
I have since updated AccuBattery (which cleared all my history!) and started self- recalibrating the app as their website suggests (you go down as low as you can, and start charging until drawing ampere really finishes at over 100%). After a few iterations, hopefully the app will show more accurate info. (Or not, I will just come terms with it!)
https://accubattery.zendesk.com/hc/en-us/articles/213575425-How-to-manually-benchmark-your-battery-health
İ think accubattery calculates with the Design capacity of the device, with the the Option to charge up to only 85% you would have charged up to 6800mah vs. 8000mah 100%. But i could be wrong too
Just not to open another thread. I have a similar situation with my tab s8+. All apps that do something hardware/battery related report the battery to be 9800mah and not the Samsung claimed
10090.
As for now I'm letting sccubattery do its reading, but so far battery life has been ok for a tablet with high end Specifications. On average I get 8 to 9h of SoT on average not very demanding usage.
Yes my S8 has also a considerable difference between Samsung's advertised battery capacity (8000 mah) vs the capacity apps like AccuBattery read (7760 mah). That's probably their way to prevent users from overcharging their devices.
On top of it, I have also found that my tab can go quite a bit after showing 100% charged. Following AccuBattery's re-calibrating (re-benchmarking) method l mentioned earlier, in one charging episode I saw my tab going up to 8700 mah or so until it started showing 0 or negative charging values about 40 mins after it showed 100%. Having overcharged my tab a few times this way, AccuBattery now shows about 100% for battery health. Obviously this isn't a good way to charge your battery in terms of its longevity, but it might help to calibrate your new device with a battery app. When the % reaches 100%, the estimated capacity on AccuBattery is normally much lower, something like 6700 mah, as I initially got. I need to do more tests, but I find the leeway Samsung spare is a bit too much.
Interestingly, I have also found quite a bit of variability in this 'fake 100% battery' setting across different manufacturers (or at least different devices). I am applying the same recalibration process on my Xiaomi Pad 5 Pro and OnePlus 8T. They are both about 9 months old. My OnePlus behaves somewhat similarly with my Tab S8, showing about 10% extra capacity after 100%, whereas my Xiaomi really stops charging when it reaches 100%.
Hey. This is my stats on my S8+. I recommend trying to completely discharge the battery to 0%, charge to 100% and wait until current is 0 mA. Do this min 3 times in row. Then you will get a more accurate reading
