That looks pretty damn good.
I was just about to post a thread. Something is draining my battery life and causing Android System to be the highest battery usage. Check out below.

Auto brightness.

Not to jack your thread.
But I used my iphone at work to watch videos, ect while there is downtime. I usually watch while it's also on the charger
For the Note series, does anyone know if that "kills" my battery for long term?
I know you can replace battery, but just wondering for future use.
Thanks.

Issue with battery drain due to android system is real
All three people I know that just got the Note 4 were experiencing the same issue I had with excess battery drain with the always generic "android system" taking more battery than anything else including the screen.
I downloaded an app called "System Tuner" and looked the CPU% for Android system and it was a constant 3-4% when the phone was otherwise idle.
I found a post at http://support.t-mobile.com/thread/80459 where they were experiencing the same issue (lose around 12% battery an hour with android system taking a huge chunk of battery). The person from that post was able to address the issue by turning location off, rebooting, turning location on, and rebooting again. After I did this I saw Android system idle at ~0.6% - 1.1% instead. So far I'm getting much better battery life but I'll need to give it some time to know for sure.
Hope this helps!

mine took about 2 full days for everything to finish syncing, downloading, indexing, etc. I had books, news articles, pinned music from google play, etc.
Once that happened, everything is now "normalized" and I'm getting better battery life than I was with the note 3.

Short answer: Maybe, it depends on how you are doing it. Using it while it is charging is not necessarily bad but watching videos and keeping it plugged in while the cell voltage is pegged at 100% will likely deteriorate your battery faster.
Long answer + tips:
Lithium ion batteries are great - they are light, can be made very thin and have excellent energy density but they are also very finiky.
Things to avoid doing with a lithium ion battery
-Charging to 100%, leaving it plugged in overnight is a poor practice(high cell voltages reduce the service life*, stopping the charge at 90%[4.10v] can double the service life, stopping the charge at 80%[4.00v] can quadruple the service life.*)
- Discharging the battery to below ~20% (Li-Ion batteries are somewhat sensitive to deep discharges)
-Charging/exposing Li-Ion to elevated temps or below freezing.
*service life is defined by when a battery can only retain 70% of its rated capacity. Most consumer batteries used in mobile devices have a service life of 500 charge discharge cycles.
It is not uncommon for batteries to lose 30% capacity in 1.5 years or less. Changing your charging and handling habits can double or quadruple a batteries life span.

LOL your picture took up have my damn screen on my 1080p laptop with 15.7 in screen. It was crystal clear too.

On my 2nd charge, auto brightness. Pretty freakin' amazing battery life....
15.5 hours off the charger with 8+ screen on time!

I got awful battery life on the first charge cycle. It drained 50% overnight. 2nd charge has lasted amazingly long and I still have 64% after 12hrs of average use.

First charge. Battery life has been phenomenal. Brightness on auto.

Did u use any power saving features to achieve that time?
Did u use any power saving features to achieve that time?

Definitely improve battery with recent update and I'm a power user

After the latest update

I dont know why but my phone goes from 100-90 in less than a hr with minimal use while the screen is set at auto, also in the leaving it unplugged in the night the battery also drains like 5 points.

I've been at full brightness and using the hell out of it non stop so far, and I'm at 35% with screen on time at 3hrs 40 min.

Battery capacity less than it should

Hey all,
2 days ago, I got my Op5. Very happy with the phone, except for one thing : accubattery says that the capacity is just beneath 3100mah, instead of the 3300mah it should have. I let it run down and charged it to 100% and kept it on the charger for about one hour after that, still around 3100mah, according to accubattery.
How are your batteries? I'd like to know if this is a widespread issue.

How do you know that accubattery is correct?
Alan

Same here, but even lower. After 42 cycles is around 3000 mAh.

Well, since it is measuring the amount of current going in the actual battery, after some cycles you can assume with quite confidence the actual battery capacity. Besides, it will actually plot the measurement, so you can actually see if the data makes sense.
I'm curios also about the actual capacity, because this would be an indicator of why I have seen so much variation about the battery life on different handsets.

Man, I really don't care. Best battery life ever! (I came from OP3 and OP2 before that)

This app shows significantly lower capacity in almost all phones. To determine capacity you have to discharge battery completely (which is not 0% reported by system) and charge it with precise measurements (5 seconds sampling rate like Accubattery isn't enough). This app is like cancer. This is fourth thread in last two weeks about this **** app. Only things it does well is reporting false data gathered by pseudoscience method and drain battery by wakelocks. Do you need to mess up with battery stats? Get Google battery historian.

So, how some users like the one above achieve 8h SOT while others like myself neither 5. I'm even never play games almost, which is typical a drain source on phones.

There is no typical drain source. Everone has different apps installed, different usage, different settings... etc. I can achieve 8h SOT or 2h SOT too. Do you really think, that 10% of reported battery capacity loss would make 60% higher difference in SOT?

Nexus 6P Replaced battery health

Hi all,
Recently I have exchanged a battery at a local service provider, battery they showed before installation seemed as legit as they come and after replacement phone felt way more agile especially at a lower battery charge levels. So I was happy until I started investigating poor SoT that I thought at the time was due to the Oreo update. After some time, resets and reinstalls it feels like the system is as healthy as it can be for now, but Accubattery shows 83% health at 2,853 mAh out of designed 3,450 mAh. That is only after few charge cycles, but I am still worried that it might a permanent battery hardware issue. Right now at latest Oreo build with elementalx kernel running a wingoku gov profile I get around 3 to 3,5 hours of SoT with little use, over night after 100% charge phone looses around 10% percent by the time I wake up.
If anyone has any insight into similar issues and can confirm Accubattery health stats credibility I would really appreciate.

Sorry, but you got a bad replacement battery. It happens. Although it just provides an estimated value, I've found Accubattery to be a very solid indicator on the phones I've used it on. Since your battery is barely above 80% it takes the guesswork out of the equation. The battery capacity estimate converges quickly to a value after only about 3-4 charges. That's it. It's not something else with the phone. It is the battery itself. There are literally dozens of threads discussing which batteries are good replacements and from which sources. Buy one of those and your problem will be solved. There are some Accubattery haters out there, but I guarantee based on what you are saying, your battery is a dud. With a fresh, high quality battery you should be seeing very high 90's to low 100's. Yes higher than 100% because some batteries sold actually have a higher capacity than rated. Try to get one of those.

Thank you for a reply.
At this point I guess I will just have to live with it until I buy a new phone, I only decided to give this one another go since I love it and do not see anything on the market now that would appeal to me as much as 6P did at purchase. But I do not want to spend more money and time on this, just wanted to make sure this is not a software issue. Software I can tweak, but battery replacement yet again is too much.

AccuBattery says my battery health is ~90% :-/

Now the question is, can anyone install AccuBattery and let me know after a couple of charges (needs to be charges larger than 50%) what your battery health says it is?
I expect your response to be delayed by days obviously, but if you can confirm below that you are doing it I will appreciate it.
I'm starting to think that I got a lemon, the SOT is obviously different from anyone else but this is the first time that AccuBattery tells me that my battery health is less than 100% on a new phone, and when I get less SOT on such phones AccuBattery correctly confirms my suspicion every time (sample size 5 phones).
For visibility of everyone, hence the question, I want to see if this normal for this phone or just a defective battery.

I got the same thing with the OP 6, the battery capacity mah was 2933 instead 3300, 6t says 3378 instead of 3700. I don't believe it's accurate. Just did my first full charge charge after I got it Monday. Battery seems solid. Ampere says Max Capacity 3700

Says 3388
But my battery is solid

Will test with a device soon and see if it is accurate or not!

93% here. 3,437 out of 3,700 based on 7 sessions with 174% charged for a total of 5,981 mah total. I received the device on the 2nd.

Here's mine. I got mine yesterday.

same here - 3450mah by accubattery. my 5t shows 86% 2850 actually.
pixel 3 (not xl) - show 99% as specified =\.
is that means 1+ lies to us?

I was literally just looking at mine last night. Gotta say I'm a little confused... No way a 4 week old phone should go from 3700mAh down to 2915mAh capacity...

Mine is down to 3300. Either AccuBattery needs an update for the new OS, or the background battery optimization is playing with AccuBatter readings?
Or maybe we are getting weaker batteries but I hope this is not the case.

most of us seem to be around 94% give or take. Maybe it's the app, maybe something else. As long as we are getting those awesome SOT times everything is good and we should not worry too much.

I have been using Accubattery since my Oneplus 5. On my brand new Oneplus 5, Onplus 6, and Oneplus 6T - they all started out from day 1 at about 93%.
Either the batteries are starting out a bit lower, or Accubattery isn't accurate.

My note 9 was always less with accubattery too

This same exact issue was reported with the 5T here: https://forum.xda-developers.com/oneplus-5t/help/battery-health-accubattery-t3735499

The application is not accurate.

Edit: Sorry about the necro...I was looking into this issue and was glad to find someone talking about it and wanted to contribute.
New phone and mine says:
Mine says 89%
4906/5500 mAh
Based on 6 sessions with 283% charged for 13883 mAh total.
I was kinda wondering how accurate it was too...I know it has to use some kind of modeling, instead of measurements, to get those numbers...but I was kinda expecting it to be more accurate...apropos of nothing I guess.
I stop charging around 85% (missing a couple times and 100%ing overnight), but other than that, I dont push it hard.

I had the same issue..
charge your phone one time up to 100% and then leave it on charger an additional hour. you will see, your battery health goes up to 96-97%.

Ignore these stupid apps that measures your battery health. They can't do it in a reliable way anyway.
As a bonus if you don't worry about this false information you'll live 5 years longer, good or bad, you decide.

Tbh I given up on my battery health for my 6T. A phone is suppose to be used. Just trickle charge it (Charge it bit by bit). Avoid charging over 90%. It doesn't matter if your battery health is low or not. If your battery life sucks two years later, you can just go to Oneplus support and replace the battery. It may cost more than a replacement battery, but it guarantees that the battery is new (not a year old) and you don't damage your phone. Sorted

is accubattery accurate?

I have a tmobile galaxy s10+ snap dragon and I noticed the battery drain is really bad. So after having it for 3 days I checked out accubattery and it says I have 4% wear already.

Hmmm...

Mine only shows 3900 mah for the estimated capacity on the health screen... I'm pretty mad about this. Only thing I can figure is it hasn't been completely depleted yet, the lowest I've taken it is about 15%. So maybe they bias more charge capacity for the last 5-10% to help prevent people from having their phones die kind of like how cars will often have 20-30 miles left once the range falls to 0...
Or I got a bad phone or samsung lied.....

I completely agree I am starting to wonder if I have been lied to or they have a reserve battery or something.
Also I have dropped 13% battery in 4 hrs of phone being idle at full signal..

5% of your battery is kept for recharge reserve, Android has no access to it, it's handled by the firmware and Accubattery obviously thinks your battery is consumed since it counts 200mAh is missing, that's completely normal and they should update their app to keep that in mind.

Youre saying every phone does this though, not just samsung keeping it from bottoming out? Because on my pixel I never observed that shortage when it was brand new either.

Also as an update if you go to settings and read battery info they say 4100 Mah is not guaranteed (Samsung's support sent me there)
