I recently discovered the app AccuBattery which can estimate the actual remaining battery capacity in mAh based on a few charge-discharge cycles.
It would be very interesting to hear from you Note 8 users what your estimated battery capacity is. So, if you wouldn't mind. Please install the AccuBattery app, leave it on the phone for a few cycles, and answer the following three questions:
What is your estimated battery capacity?
For how long has the phone been used?
Are you a light/medium/heavy user?

I had had the phone for a month. I have never had the declared capacity. I have been stuck at 96 % capacity for a while.
Added a poll now because ... Polls are fun!
Was initially at ~3450mAh (105%) when I got the phone. At 3410mAh (103%) now, after ~2 months of use.

I found this thread searching on Google because mine's been average 3,000 capacity each charge cycle (but the overall health is still at 3,241 98% but decreasing every day), after having owned the phone since release. I'm a moderate user, and follow the 80% charge guideline most days. Is my battery defective or maybe Accubattery is wrong?
I know Samsung promised 95% battery health after 2 years. But if mine already hit around 98%, I'm concerned.

It could perhaps be that the battery was lower capacity to begin with, but the rate of degradation could still be the same. This brings me to a feature I was wishing for in AccuBattery: being able to plot calculated capacity over time. To reduce variance in such a graph, the app could filter out measurements based on <60% charging.

I did get 3,300++ when I first got the phone though. But if it's a problem with my battery, I'd want a replacement. I actually do a lot of small charges (like 10% at a time) most of the time so perhaps that causes inaccurate measurements. I agree that I wish I could filter data out to get a better idea.
What does "sessions" mean on this app, when I installed the app and did my first charge it simply stated based on 5 sessions bla bla bla

Sessions are charging sessions, so you need to charge your phone 5 times. But I think it only counts a certain percentage charged as a session.
It is interesting that nearly half of all people who have voted have more than 3,300 mAh estimated capacity. Hard to know whether this is because of inaccurate measurements of charge/discharge or variation in actual battery capacity.
I now have a Note 8 myself, an SM-N9500, and based on 4 cycles it is 102% or 3,375 mAh. Nice to see Samsung actually delivering slightly more capacity than promised rather than the opposite.
Edit: The estimate has now stabilised at 101% or 3330 mAh.
Mine is 3160 based on 5 sessions
3400

Hey, just wanted to let you guys(and gals) know that this app works perfectly on our axons: Battery Charge Limit.
https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002
It does exactly as the name suggests, stops the battery from charging beyond a certain percentage, thus for example if you set a limit of 80%, your battery will preserve its health for around 1500 cycles instead of 500 cycles of charging to 100% before degrading by ~20% of its total capacity.
Enjoy the app guys, tested on B19, stock kernel, rooted.
So the way to have 1500 cycles is to only use 70% of battery at best. Because going under 10% is not exactly good for the battery either. I don't want to have an even worse battery life, so I think I'll pass, thanks though!

Don't go under 90ish as you will stop charging whilst quick charging and will damage the battery even more than if you didn't use the mod so just be carefull

Dont let them fool you, you dont need this app. The charging controller of your phone actually already has its safety margin built in. Same on the low end. This means you can not charge your phone to its physical maximum anyway, it will show 100% whipe the physical charge in fact is ~95% and will shutdown showing 0% while physically there is still about 10% of power left. So your battery is safe from this kind of damage anyway.
If you want to extend your batterys lifetime for real, try to charge it as often as you can, keep the charge as high as possible. Flat charging is the magic word. This is what your charging controller does when your phone is connected to ps for longer when it shows 100%, it in fact lets it deplate 2% without showing and then charges it back, thats called trickle charging and is the best treatment practice for our bateries.

Samdung pretty much confirmed they do this (or better) in the S8 and later (and possibly the S7). But has any other company confirmed they have battery longevity tactics built in?
Personally I use AccuBattery since I've had it for a long time as a charge alarm/monitoring tool. I use a 1 amp charger instead of the 3 amp charger that comes with it and charge my phone at low amps and voltage which prevents the battery from heating up. So low charge, low heat. I don't want a degraded battery in a year because I don't know when I'm replacing this thing.

AccuBattery is no good for giving an accurate estimate of the actual capacity when you're charging at low %s. For first 50% it'll calculate something like 3500mAH+, for the last 50% it'll estimate 2000 or lower. If I had to give you a rough estimate of what I actually think it's at, it's roughly 2900-3000mAH. When I first got it, I estimate it was around 3100-3200 a year ago. I HATE that phones no longer have replaceable batteries. That's half the reason I wanted an LG V20, I could just murder the battery and just pop in a new one every year. Sadly the V30 is sealed, following the BS trend of planned obsolescence. Thanks Apple.
Oh and I almost forgot, I typically charge my phone from 20% to 50% after it drops 30%. Then sometimes once more if I use it some more. On average I charge about 50% worth a day without going over 50%. Even with such light battery usage, keeping the battery 30C or lower 99% of time, and keeping the voltage below 4.1 again 99%, it's still degraded at least roughly 200mAH in a year. Rarely when I know I'll need longer battery life I charge it to 80%. It's a cheap quality battery. ZTE cut corners. This was my first, and unless I have no other reasonable options, it'll likely be my last ZTE phone.

can you TL;DR this for me?
-So i better keep charge between 20% and 80% yes?
my old sony phone form 2011 still works nicely, as it had Quality battery (over 2000 cycles already) yeah does not last long 2/3 but still. useable.
And i agree, replaceable batteries is must have function, My old S3 and S4 worked for "ever" because of that, every year new battery and another year of usage! (s3 still going strong since 2012 !!! )

Apple has been using enclosed batteries for like 10 years or so.
You can do better than the app by setting a lower maximum voltage on the Axon 7 instead. I posted about the discovery awhile back on that thread https://forum.xda-developers.com/showpost.php?p=74746734&postcount=1353

Essentially, yes, that's what I keep hearing whenever I dig for information. If any of the stats of AccuBattery are accurate at all then it also supports that going over 80% causes multiple times the degradation that charging up to just 80% would. These days I try not to go over 70% based on app estimates of degradation. These days I need more than the 50% I was previously charging to.
My battery has only 1k mah left from the 4k? How is it for other people?
Since when you have been using your device? Mine is year and a half old and i have the same sot as you.
The screenshot says the display has approximately used 1196mAh of the battery's capacity. This can be during 1 cycle of charging or even several ones (of not charged at %100 ofc)

Here is the screenshot
This can have multiple reasons, for accubattery to show a reasonable number you should at least use it for a week.
The supercharging messes up the mAh count... if you only supercharge 20%-50% all the time accubattery will show like 4500mAh.
So just keep using it for a while and see what happens. If you phone is one of the first that were shipped it is already 10 months old. if you use the phone a lot and always drain the battery and charge it to 100% always then the battery will wear out much faster. also heat can wear the battery out over time if you game a lot or live in a hot country then it can affect your battery life span too

Thnx for the clues, now is uodated to 4040 mah, is not accurate as the name of the app, lol my mate 10 pro is 5 months old and is about 6h30 screen on time and performs well my question is it is better to charge when it is on 30 % or wait till he turns off or to make short charging when it is on 50 or 60 per cent. Which method will keep the battery life

first of all: if you are happy with the battery, then dont focus so much on the numbers of an app. If it is enough juice for your days then everything is fine.
Accubattery explains it pretty well with the Charge cycle wear (or whatever it is called).
Generally speaking draining you battery to 0% or chargin it to 100% both means stress for your battery, it is bad.
So try to never drain it to 0% and never charge it to 100%. Accubattery has a scale fot this they call it "battery wear" and chargin from 0% to 100% causes "1.0 cycles" which is maximum stress for your battery and very bad.
If you want to have "0.0 cycles" you should best keep your phone between 45% and 55% all the time. Of course that is impossible but if you have the chance just focus on never letting it drain to 0% and never letting it charge to 100% (the last 10% take too ****ing long anyway, also do not charge over night. 100% for the battery is like a small car with 20 people inside... when the charger keeps the phone at 100% for 5h or so it means high stress over a long period of time).
My last charge charge was from 11% to 85% the wear is only "0.3 cycles", so its only 30% stress compared to charging to 100%. Lucky enough for us the battery of the mate 10 /pro is so big, we can afford only charging to 90-95% and still have enough battery for a whole day.
You shouldn't check it from. This tab anyways
Go to health there you will see the true current capacity of ur battery
Has anyone checked the ROG phone "Battery health" on AccuBattery Pro? Mine is showing Estimated Capacity as 3,548 mAh, Design Capacity 4,000 mAh. I completely discharged then charged to 100% as calibration. Brand new phone.
Mine is showing 3,531mAh after around a week of usage.
Someone should report this on the Asus forums
mine also show 3500mah after 2.5 weeks of use
I have posted this issue on ASUS's Forum
https://www.asus.com/zentalk/thread-249329-1-1.html
Please feel free to add your battery capacity screenshots on their forum so we have a reference for the future
Mine's at 3462 after a little over a month. With a health of 87%
OK, then. We shouldn't be concerned. The proper way to measure battery is more complicated than what AccuBattery does (the proper way involves measuring battery discharge at a controlled rate). Since many of us are getting similar readings on AccuBattery, it's probably that AccuBattery's method isn't accurate.

Same here: 3536 mAh 88% health with Accubattery first charge out of the box after discharging to 15% following first power up.
Either Accubattery has a problem with our phone, or Asus is ripping us off.
If the batteries were bad, we'd all have different readings.
I am guessing the AI charging might affect the measurement from AccuBattery. However I also don't think the battery capacity is full 4000 mAh. My last phone from Motorola has a 3000 mAh battery on the spec chart, but the battery itself prints 2810 / 3000 mAh (min/typ). From the ROG phone tear down videos, this battery isn't marked though.
From the asus zen forum the only solution the person provided was to bring the device to a service center to get it tested
I maybe wrong however with batteries these days it only ever uses a percentage so that there is redundancy for failure and to preserve the battery life.

Samsung does that. Note 9 is 4000mah but Accubattery says 3800mah on new phones. Every one of them.
Power reserve to not kill the battery early.
Anyway, 3500 mAh seems like one heck of a left over reserve.
Our batteries should last 5 years at least
Same "problem" here, but maybe it is because program has small amount of gathered data about battery usage. I did full discharge and full recharge yesterday, and goz about 3567mAh, but ill try to calibrate battery and use measuring app for longer time to get more accurate results.
Ps: I am using only slow charger to avoid overheating to eliminate battery damaging when recharging
I have not checked my ROG Phone in any 3rd party apps as I have not had a reason to question the 4,000 MAH
It is not a problem, lithium ion battery deteriorate faster if kept fully charge all the time or when discharged to low. Since most people have the bad habit to plug their phone all the time and keep them full for a prolonged period of time, oem have to be creative to fight this. Some will show your battery is charged at 100% while in reality its only charged at 90% .That is what your program most likely reading.
lithium ion should only be charged at 100% before you leave the house, i tend to keep mine between 50 and 90 usually . With quick charge there is no reason to keep a phone plug overnight, 10-20 min before leaving the house is plenty.
I have turned on AI for battery charging and as soon as my Battery reaches 100 it stops charging which is good enough for me to have faith in the charging technology in the phone and battery capacity.
I do leave mine plugged in over night however with the right equipment to check its hard to get a good understanding of whats happening. Theres inbuilt battery health tools so i would always advise using these and going through the features of this over 3rd party jank applications and trust them. Its the only tools Asus are going to support in any diagnostic troubleshooting.
Hi guys, I am returning after some time of usage and charging. After some charging cycles I have to admit my battery capacity is "increasing" - well better say, it is getting used to be charged properly. Now I passed 7 full charging cycles, but after 3rd one every next charge had more mA. I started at 3479mAh with full battery, now I ended with 3711mAh - hope it gets even better (I'll be glad for at least 3800, but who knows?). Everytime I tried to charge only when I was below 3%.
I have to say I am using slow charger with 5V and 400mA current. Battery checker from mobile manager was not detecting any issue with this way of charging nor AccuBattery Pro. I also know, that batteries shall be charged only about 80% of its capacity, but I am still sceptical about that rest 20% so I am charging to max everytime.
Hope I helped...
...another time passed and I am back with another results. After a lot chrging cycles I am stuck at between 3500-3700mAh of total capacity. I was searching around whole internet and found out, that phone manufacturers are "decreasing" battery capacity with SW at 90% of total capacity to prolong battery life and avoid battery wear, because everytime you charge the phone, you think you are charging to 100%, but in real you are charging to 90% only - rest of 10% is "hidden" to save your battery life - due to my calculations and testing it might be true. Anybody else had something different, so we can compare it?

Hello all,
Has anyone else tried to discover their actual battery capacity?
After about ~6 charges and discharges 3C Battery Manger tells me my battery capacity is 4549mAh not 4614mAh.
I may try AccuBattery which a lot of people really like but has given me strange results in the past.
If you've tried to discover your actual battery capacity with good results, what app did you use and what was your actual capacity?
AccuBattery is giving my capacity to be 4,888 mAh. Which is nice if it is accurate?

Hey pems82, thanks for the reply.
I ran AccuBattery for a cycle or 2 and it gave me an estimated capacity of 4694mAh so who the hell knows...
I would like to believe AccuBatterys estimate over 3Cs Battery Manager estimate
My estimate is based on 31 cycles. It becomes more accurate the more cycles you run it through.
I think you would need to do at least 10 charges where you add at least 20% to get a decent accuracy.
