Mines been quite poor, but it's been downloading and installing apps over LTE for hours. Not exactly a fair benchmark.

7 hours of screen on time with 10 percent battery lef. I'm satisfied

Same here. But when i finished installing it, I fully charged it around 9pm last night and it just went to 10% today at 1pm

I'm at 4h 40m screen on time, with 36% left in the tank. I put the mid batt saver on at 65%. At this point I'm pretty impressed.

The battery is downright impressive!

Yea I don't know what happen but my last 2 charges after that has been around 5 hrs max. I didn't do anything different. But I'm still satisfied with 5 hrs SOT

One thing that isn't mentioned enough is battery maintenance and care. A carefully maintained battery will last longer, and store more energy, therefore providing more time between charges. I have a lot of knowledge about lithium based batteries in the hobby grade Radio control models. I have been maintaining lithium polymer and lithium ion cells for about a decade. So I would like to compile some tips for everyone.
1) Heat. Heat causes the most damage to lithium based batteries. Leaving your phone in direct sunlight, as most of us know can cause your device to catch fire, or even explode. Water is useless in extinguishing a lithium fire. Lithium cells will burn under water. This isn't new info to most of us, but I mention heat mainly for these reasons;
A) rapid charging causes increased heat in the cell. This increased heat degrades the cell, causing reduced cycle life. This is significantly more concerning on modern phones without removable or replaceable cells. Therefore you should avoid rapid charging unless it's absolutely necessary. Especially overnight. If your sleeping then there's no reason to rapid charge.
2) Voltages. Voltages are also very important, but since these are managed automatically you don't need to be overly concerned about them.
A) 3.0v this is the minimum voltage at which your charger will still recharge the cell. Most phones will shut off at 3.3v or 3.2v. This is your 0% charge level. The reason this is significant is that once your phone shuts down from a dead battery it is important to recharge it within a reasonable timeframe. It may take a week or 2 for the cell to drop those last few tenths of a volt, but once it does it's over.
That said, it is good to completely drain your battery occasionally because this helps the OS calibrate a more accurate battery charge percentage.
B) 4.2v is fully charged. This is your 100% charge level.
C) 3.7v is the best voltage for cell storage. This is approximately 50% charge. That is why your phone is usually about half charged when it is unboxed. (But who stores their phone lol)
So the important takeaway from all of this is, avoid rapid charging when you can, and once your phone dies, recharge it soon after. -Chris

Not bad. Got me through the day. ~4 hrs sot

Too early to tell. I had like 3.30 SOT. After a couple of charge cycles it's getting interesting.

I went through 16 hrs of my average use and had 39% battery left before calling it a day. That's at least 30% more than what I was squeezing out my Note 4 on 6.0.1. Idling overnight for 7 hrs the battery went down only 4%.
I'm really impressed so far!

People getting 6+ hours SOT, can you let us know what your setup is like? Are you disabling stuff? Running dark theme?
Thanks!

If the question is for me....yeah, Material Dark Theme. Nova Launcher, no stuff disabled (Wi-FI/Loc/BT etc.). No app power saving. Hi resolution. I run "Optimize" once in the Device Maintenance menu.
I'll post a stats screenshot at the end of the day

I don't really trust any battery benchmarks right now..... the phones are all brand new...... lets all wait about 12 months and re-check them; While compared to the Note 3 my Note 7 replaced I am generally happy with the upgrade to the Note 7, the sealed battery is really pissing me off. I was using the Zero Lemon 10,000 mah batteries on the Note 3. I can almost gamble that the battery in the Note 7 will be useless in 12-24 months depending on usage and then we are stuck with $800 bricks unless someone figures out how to safely open the phone so we can replace the battery on our own.

Yesterday I had 7.2 hours of SOT. First few days were a little less, due to initial geek out, setup, testing. Seems on par with the my Note 5 and S7e.
What this shows me, is that I need to spend much less time in front of a phone's display....

For how I use the phone, I can easily get over 7 hours SOT....with 10% or more left. Yeah... I disable all the Sammy/Tmo bloatware I can....as well as Lookout, Android Pay, Facebook stuff...and a few others. I always use Nova 3.3 (the last before they switched to the horrible white themes of LP & MM) and I've been using a minimal black theme from the Sammy store, that has the color rings around some icons. Love it. I don't use auto brightness...and normally have it about 30-40%. I also don't ever use NFC, so it's disabled. I rarely use bluetooth....and i don't do any gaming really. I imagine if you're doing those things...battery life will suffer a bit.
Though I definitely think it helps to have an all black theme going. Settings, dialer, app drawer....solid black. And don't have the screen too bright of course.

I don't know how good or bad it will be but in my opinnion it's going to be average and its a note so i'll be using the phone a lot. I just bought the wireless charging case from the T-Mobile store i work at My coral blue comes tomorrow !!!

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.

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

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...

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...

accubattery app says I've lost 15 percent of my charge./ health

Is this right.. Of so it means after a year I would of lost 30 percent as I've had the phone for 6 months... This surely can't be true... Damn I miss the replaceable battery..

What your daily batre statistics are like. If you can still 24 hours and about 4-5 hours sot it is still good and in tolerance

Thanks battery still good... But to lose that much in 6 months not good

Hello i have also an issue , i had always used built in device maintenance feature , and it always told me after 100% charge, remaining time was about 20 hours, but for 2 days after full 100% charge, device maintenance tells me i had 12 hours left after full 100% charge, this is weird , i had done no change to any setting , except installing some games which i play , but why they reduce battery timing if i don't play them ? only installing them reduces battery time ?

Well i do not know for sure about this, i hardly ever use fast charging and i do not feel the battery drop since the first time usage a year ago. I can still use within 24hrs and get 8-9 hrs sot

I lost 28% in one year. Really says a lot about the quality of these batteries in the S7. By comparison, after a year my S6 lost less than 10%

no one gave me any answer ? please i need to find some clue about it, why built in device maintenance feature says my battery life is only 12 hours after 100 % charge ? just few days it was telling about 21 hours left , i do not made any changes , just installed few games, anybody has a clue ?

I love the Accubattery app and use it in all my newer phones..It's education is spot on too..
Most people fully charge there battery everyday..Going over 80..Or 90% regularily, especially 95 and 100% having phone go to 4.3-4.35v is just plain bad for the overall battery health of a lithium ion battery..What it will do is degrade the longevity of the battery where as normally one should get 500 cycles to get to 75% health left it will get there much quicker and I see so many that have phones, like this one and other non replaceable battery models that have toasted batteries within a year..Toasted as in the life is much shorter and drains so much quicker and needs recharge by 2-4pm..
As for fast charge..Jury is still out..Battery researchers say at current levels of less then 1c fast charge rates it shouldn't make a difference but I say it does..At least a little..So I only use it when needed..Once or twice a week (and only up to 85%)..
But outside of that..Even when handled well,some batteries just aren't up to snuff and die quicker..

They are about the same and like all lithium ion's, will suffer same fate from over voltage (100% charges all the time)..And actually apple batteries seem to fall off a cliff sooner then most..We all know people with iPhones (that are older) that will hold far less a charge and many that hit 50% and die needed recharge immediately...Is what it is..
But if u do things right one can extend the overall longevity of a battery by a fair bit

Another thing to keep in mind and very few know this about the S7 Edge (and u can search and confirm this online and with Sammy),is that the real (useable) capacity of the battery is 3521mah and not 3600mah.. and this is because it is a 3600mah @ 4.4v battery but Sammy locks it out to max at 4.35v (which is actually a good thing for safety and to help with overall longevity of battery life thus reducing the useable mah to 3521.
So in my Accubattery I custom set my battery capacity to that 3521mah number.
And on a side note..I wish Sammy and phone manufacturers would build setting into the kernel that would allow a user to set a charge limit (say 80/85/90% for example) that would stop the charge or just trickle when left plugged in and not have it force it to 100% and keep trickling it at that max ...That is actually the main cause of battery life killer..Plugging in at night..Gets to 100% quick then has hours at overvoltage (plus higher temps) and those two things alone are 95% of cause for lithium ion killer

You can check your capacity using this :
https://www.reddit.com/r/GalaxyS7/comments/694urh/how_to_gauge_your_phone_battery_capacity_after/

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

Battery capacity after one year of use.

So i got my Oneplus 6T about 1 year back. And today i decided to check the battery capacity. Phone was drained to 0% and repeatingly turned on until it showed the low battery warning. Then i used a regular 5V 2A charger to charge it turned off overnight. I have been limiting the charge the past few months to 80% since I am not long away from a charger anymore.

~3200 according to AccuBattery since release when I seem to recall it showing ~3600.

For me, it was showing 2900 only after Two Months. I checked via Accubattery and after some GoogleFu I found that it is common in all OnePlus phones. Even those you just bought.

Chinese batteries never produce their rated output. You'll only see accurately rated ones from Korea and Japan.

I testet my 6T now too and saw only ~3000mAh going in.
The App AccuBattery is showing Battery Health is 80%

Don't trust apps lol. An app that uses battery and resources on the same battery its analyzing isn't real lol. Tells me I will get 5 hours screen on time, but I always get between 8-10 hours screen on time and my standby sometimes reaches 30+ hours lol

For the first i meant that the charge i checked with a Ampere Meter like the Threadopener.
And Yeah, looks like it's showing **** at your Device. But i think it's showing not bad at my device. it forecasts the SOT to 10 hours but i only come to 7-9.
Already i did the App kills with ADB from the Debloat Threads.
Blocked some Data-background at several apps.
Installed Naptime and optimized light doze
I can't show pictures, i don't see the attachments place

Not familiar with Japanese batteries. But last time when I knew Korean batteries, it was Samsung Note 7.

This is about what I'm getting now with no tweaks no root on stock OOS 10.3.3. I was at 7.5 hrs sot and 27 hours total last cycle. So this is good info. It means the 1+6t I just bought doesn't need a better change. Yay. ?

I vape, and play with RC model planes and drones as a hobby, so I have lots of experience with rechargable batteries. That experience has taught me that Chinese manufacturers always overstate both the capacity and output of their batteries. If you want to see which manufacturers produce the best rated LiPo batteries (the type used in handsets) then check out various hobby sites.
Phone manufacturers using these Chinese batteries are aware of these exaggerations, so they account for it in the published ratings of their devices, making those numbers relatively accurate. The problems come when trying to replace the OEM batteries when they wear out, because it's the "wild west" with no regulations in the aftermarket, rendering the claimed performance of these Chinese batteries useless for comparison purposes.

I have been using Accubattery for as long as ive had the device. almost 2 years now. The battery dropped to 87% in about 2 months of usage and as been in there since.
