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.

Hi,
Last night I purchased my S2 and am in the process of priming my battery. Could anyone tell me what is the standard (in the box) battery capacity that is achieved after the going through a few cycles of charge/discharge I should expect?
Coming from a HTC Desire HD, I am so far impressed with the S2, way better in every respect.
Thanks for your input
Didn't know the battery capacity could be variable in a battery... are you talking about battery duration?
Talking about the value reported in apps, the like of Quick System Info PRO, where one can see the state of the battery. For example, when my DHD arrived, batter was only at 3500mV. After a week of "training", a.k.a. priming of the battery, I reached full capacity of 4204mV when charged at 100%.
I am simply trying to establish where my battery is at today + how many cycles of charge and discharge it needs to span full capacity. Talking about this for example
Breaking In New Batteries - New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge your new battery two to four times to allow it to reach its maximum rated capacity.

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.

3350, 102% here.
Had my phone for 1 month 1 week
Medium use
What is your estimated battery capacity? between 3270 and 3310. now it's 3305. FG_FULLCAPNOM is 3232.
For how long has the phone been used? since Oct. 24
Are you a light/medium/heavy user? On weekdays the use is heavy, on the weekend, medium.
3,380 Only 10 days 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

Do you know if there is a difference if a use wireless charging or wall charger? Any ways. I use the wireless regular charge most of the times.

You mean if it makes a difference for estimated capacity? I shouldn't think so.
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)

Accu battery is showing battery capacity only 3600 mah instead of 4000 anyone faced this or my battery is dying

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?
