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 estimate

Hello!
I am using my galaxy s7 edge for 7 month , and my battery has started to be very bad..
I checked with an app my battery capacity estimate.
And it said that I am actually using 74% of my battery.
I have some questions:
1.is there any way to change it and to return it to 100% ?
2.what makes it happen?
3.what can I do next time that it will not happen
Thank you for your help!!

Try battery calibration from play store

It's suppose to help my battery ? Or the only way is to change my battery to another ?

You don't need a battery calibration app. They only do what your phone (Android) can do anyway without a third party application, IF they do anything at all. Battery calibration apps are for me in the same category as TuneUp Utilities and supposed system tuner/optimizing apps that are nothing but placebo apps. But enough of that.
Apparently batteries on Android devices calibrate themselves upon every (almost) complete charging cycle. For reference.
Also, if you're concerned about your battery capacity, I advice you read into Battery University. They have section about this exact topic: http://batteryuniversity.com/learn/article/how_to_measure_capacity
It looks highly technical but it really isn't that difficult to understand. Give it a try.

Firstly, I wouldn't trust what the app is telling you. Secondly, I'd chase down rogue apps that may cause your battery drain issues (if you have any). As to how to prevent early battery wear:
- Always keep the charge ABOVE 30% - 40%.
- You can't always control it but Li-İon batteries have optimal working temperatures. Li-İon batteries don't like being cold or too warm (50°C +).
For more info on how to prevent your battery breaking, visit the site I've linked above.

Ok , but my battery still drains fast , I get around 10 hours of use and 2 hours of screen .
When I full charge the battery it's writing 13 hours left to use, and it's seems that everyone else has better battery stats.

Accubattery is not reliable when estimating Battery Capacity, i think it reports 70-80% for all users.
If you battery has intact degraded then there is no way to restore it.
To reduce battery degradation, do not use quick charge, keep your battery between 30-80% battery, but honestly this is just nitpicking, if you are experiencing bad battery chances are it's just a case of a rogue app.
Also, depending on where you live, Samsung does offer replacement for battery if the battery rated capacity drops below 20% in the warranty period, but i highly doubt that it has.
And there is no easy way to accurately test your battery capacity.

No it doesn't, for the first 2 weeks with new S7 Edge it reported 100% and after 3 month now I'm at 95%. So it seems to report the value very well...

Losing 5% of the battery in 3 months is not at all normal. Normally you would lose 5-10% after 18-24 months of heavy usage, that's just how batteries work.
Or let me reiterate Accubattery is inaccurate for most people, there is really no way to accurately measure battery rated capacity on a software level.
Sent from my SM-G935F using Tapatalk

Why do you think accubattery is not accurate? If you know the time and mA of charging you could calculate your battery capability.
For my s7 edge and after a month it gives 96%.
I think it could be right

battery life after 7.0 update is terrible, first beta was great I got 6-7 hour of SOT, now I get only 2 hours, what about you guys ? (4G always on, AOD on, internet browsing, messenger, light gaming)

My battery life is pretty bad but I don't know if that's the battery or the new software (7.0)..
For me accubattery shows that I am using only 74% of my battery every time..

Try to do a sort of calibration. Let your battery reach o% and charge to 100% for 3 times

I´m facing the same issues. AccuBattery saying that i have only 2635 mah left on the battery on my S7 edge...
Bad battery also on Nougat.

Thats a very bad advise. Lithium ion batteries doesn't like to be completely empty. That will damage the battery.
You should always keep your battery at 20-80 for maximum durability.
Sent from my SM-G935F using Tapatalk

There are different opinions about this point. Lithium battery has to stay between 20 and 80 % and you are right... but someone tell that sometime you had to descharge and full charge it completely in order to renovate the power. In my personal experience i always keep my battery between 20 and 80 but when i make it have a full recharge cicle it gives better results
Inviato dal mio SM-G935F utilizzando Tapatalk

they said that Android 7.0 would be better for the battery length but I don't notice any difference. I'm not rooted and stock touchwiz.
In the beginning when I had the phone, I installed GSAM battery monitor and it showed the battery cycle was 20 hours or more (since 17 may 2016). it has been lowered ever since. 18 to 15 and now I checked and I see 13h 35 active...

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.

Best Method to Measure Battery life/SOT etc...

Like many others my 1 year-old A2017-U's battery life had deteriorated significantly. Until yesterday it was completely stock, unrooted. In an attempt to salvage what is a perfectly serviceable phone for me, I finally bit the bullet, unlocked, rooted and installed Lineage OS 14.1 and the Radioactive kernel.
What's a good way for me to objectively measure battery life. What I'd prefer to do, is to charge to full, and then understand under typical conditions how long it lasts, day by day.
Is there a good app for this?

In my view, there is non. Everyone's phone is different, with different apps, etc. What I used is Antutu's stress test and see how many % drops after X number of tests. It can also show how quickly it drops, but only useful if you have previous tests to compare to.

Accubattery. It measures the mA while charging and takes the estimate of mAh, coupled with the percentage thay you charged. After 2 charges with more than 20% (say, from 20 to 60) it will show you an estimate of the current battery capacity. after more charges it will get even more precise, bur in my case it's been showing 2400 mAh all the time

I agree with above, Accubattery. It will tell you your battery's capacity. I bought a year old Axon7 and the capacity was down to 58%, Bought a replacement and did a fairly simple install and now all is good.

I don't trust Accubattery that much, I use a USB battery capacity tester (google for it). Plug it in between the charger and charge cable and it will show me the true capacity when full.

And how much difference does it report? I mean, why not trust Accubattery since we saw all of the results on the other thread? Before changing the battery it would report very low values like 58%, after changing it it reported about 96% which is really good

Bottom line is it is an app which will draw power when it is running, which may affect the result. I had not tested the app fully but on my old zf3, when screen is on, it reports as drawing at 500ma while the USB tester stay as the same before screen on, 1.8A. The USB tester measures the actual electricity that went down the cable while the app measures reading as reported by the phone, which could be wrong.

Question How's the battery like in details? Could you please provide screens from AccuBattery?

Hi guys, how do you find this phones battery life with cellular network on? Can't seem to find any info about it.
I am on Pixel 6 Pro and I am looking for replacement. As you can see on my screens P6P has some serious battery issues. While it's in my pocket or lying on the desk with screen off it sucks battery life like crazy. Up to 5% per hour sometimes. This is my fourth device(Google agreed to replace it 3 times) and all the previous ones had the same issues. I have tested it in safe mode too. It's that crappy modem in P6P. Btw I am unable to wirelessly charge it too. I noticed that when P6P will heat up to 39degC it will stop charging so in northern Spain I'm unable to charge my phone(unless I put it in the fridge for some time) without a cable lol.
Will NP1 have better results?

This is normal with the screen on and full screen brightness.

I am asking about NP1 and talking about battery standby with screen off performance(4,5%/h) for P6P.

2592000 pixels in NP1
4492800 pixels in the P6P
The battery in NP1 is Li-Po 4500 mAh
The battery in the P6P is Li-Ion 5003 mAh
If the Qualcomm SM7325-AE Snapdragon processor in the NP1 is more economical and online operation does not devour as much power as by Google Tensor in the P6P, you can minimally extend the all-time online usage time with the screen on.

Never been from 100% to 10% since I got the phone as I use Android auto and it charges. Will try to do a 100 to 10 tomorrow and then post it here.

This is 83% to 59% if this helps

Guys, can anyone confirm, how much SOT to expect from this phone?
Also, in accubattery and castor apps, my battery is showing 4350mah instead of 4500, is this an issue?

SOT more like 7 hours plus (varies with usage I don't play games and got 7 hrs : 40 mins sot ) and inaccuracy of battery capacity is there with many tools reporting 4350 while others 4500 like CPUX reporting the later one. Accubattery has a feature of estimate battery capacity after few charge cycles that is showing 4495 on my unit so check that incase.

It need to be 7h+ but it is not, thats the problem.
