I got the phone yesterday, trying to test it out myself today and get results!!!

First full charge is encouraging.

Wait till two to three charge cycles are complete. The battery life normally increases.

How much time it is taking to fully charge

Almost all on WiFi -- browsing, installing and setting up a bunch of apps, listening to music/podcasts for roughly an hour or so, texting, phone talk time around 20-30mins...things of that sort.

Definitely! I was impressed myself, especially since I came from an iPhone that had a depressing 1400mAh battery. In the time it took for one full discharge on my S5, I would have needed to do 1.5-2 charges on my iPhone :laugh:

Mine? Snapdragon SM-G900A

How is the battery back up guys for exynous version mine is not gud
Sent from my SM-G900H using xda app-developers app

Much better than my GS3. 30% at least.
And Charges about twice as fast.
Not kidding.

Which one do you have snapdragon version of exynous version.and how much time its taking to fully charge
Sent from my SM-G900H using xda app-developers app

Getting outstanding battery life on my g900a. Once someone figures out root for it and i get greenify working properly it should be even better.

Siting at 8H 25M 11S on Battery. AT&T S5. The thing that is killing my battery the most, Gear Fit Manager at a19% then Android at 16% and Screen at 14%. I have only charged 2 times so far since I bought the phone on Sunday, Ran it down to 9-10% yesterday but it took forever to charge. In over two hours of charge time it went from 10% to 37%. My iPhone 5 would have been 100% or close to it. Never had android phone before (really enjoying it) so not sure if this is normal or it will get faster the more charging cycles.
Thanks

I've disabled almost all advanced features such as smart stay and stuff that normally uses your front camera to identify that we are looking at the phone. I don't understand what else to disable. I even disabled edge features but still no response. I've factory reset it several times to no change

No root

There are many threads discussing the battery life of the US variants, nothing has been found to correct the Android battery drain. Even disabling some system packages has caused worse battery drain.

disable Facebook. It is contributes to that drain.

There seems to be a lot of variability out of the box. Mine has always had mediocre battery performance, even with no additional apps installed. I should have exchanged it when j had the chance, but I thought an update might fix it. Disabling this and that can make small improvements, but nothing I do has ever made it outstanding. There are some with great battery performance but I personally believe that with the exception of a few horrible apps (like facebook) there's only so much a user can do to influence battery for US devices. Either you have a good one, or you don't.

Yeah I totally agree. I have friends who have outstanding battery performance and no matter how much i try, I still get very inconclusive results. I'm big into development and nothing has solved the issue with the limited resources that we have without root

Im not sure . I know it last 2 to 3 days easy on the original pb5
The other phone updated to pd3
Dont even come close.
The update kills the phone. Im so glad i never updated this one. Its flawless
Sent from my SM-G935P using XDA-Developers mobile app

I took the update cause one of the features was better battery life and I was thinking "it's pretty amazing now I gotta get this update and make it even better"
And it's total garbage. Screw the update and screw Samsung for putting it out. What once was an amazing phone is now dying just as fast as my 6P or HTC whatever.
Samsung needs to fix this crap asap
Sent from my SM-G935P using Tapatalk

On PD3 I've been around 20-24 hours consistently usually around 3.5-4 hours SOT due to work being in an area where I get one bar of 3g consistently
-autobrightness on
-everything on GPS on high
-bluetooth to pebble and tons of streaming music 3+ hours
Compared to the s6 edge this is miles better so no complaints here
Sent from my SM-G935P using Tapatalk

Versus my Nexus 5X (1000 mah smaller battery)
Similar SOT, HUGE difference in Application battery drain (same apps installed on both phones).
Samsung is now a software company my ass.
Even the Note 4 does better on a smaller battery.
Sent from my Nexus 5X using Tapatalk

The first 2 firmwares show they are capable of producing software with good battery life. Not sure what went wrong with this update but I hope they fix it asap

Rom with the best battery life

Hi guys,
From your experience, which rom is providing the best battery life so far? I've got my S7 for a week now and not really impressed with its battery.
Thinking of rooting to be able to monitor wavelocks and hopefully improve this so your feedback would be very helpful!
Thanks
Sent from my SM-G930F using XDA-Developers mobile app

There is no straight answer to this, every rom has its own pro's and cons.
This also determines on your on personal usage, e.g number of apps, backround services , wifi....etc.
I personally use Echoe Rom, it is the best i have used in terms of performance and battery. Brilliant Developer , with faster than lighting updates.
Try out a few and test , see what suits you.

Where to download the echoe rom?

I just registered on their forum, waiting to be approved. From the youtube video I saw, it looks quite nice. It was in another language but lots of eye candy for the initial install. If you register, they suggest using your xda username as well so they can look you up I guess. I am looking forward to trying this rom though. Thanks again for the suggestion.

For the Exynos version, try the stock G935FXXU1APC8 (for Edge) or G930FXXU1APC8 (for regular S7) rom, that it the best for battery life.

Can only be invited to echoe rom now.
Battery is so different 4 every user.
I've tried all most roms and currently on. Echoe and to. Be fair there isn't much in any over stock
I get on average 6hrs sot
Best is 7hrs 50mins.
People will tell you all sort of bull**** about all there hours if sot but it ain't possible 5-6 is what you'll get average maybe less if you a heavy user.
You can only achieve a long sot time by watching videos.
I tried freezing apps
I. Use amplify smart. Network and battery saver
Have dark apps where possible and material black theme.
What's your sot because this has been one of the best battery I had on a phone and I had every Samsung since s2

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy Note 8 before depleting the battery.
Then, drop a comment if you have anything to add!

Actually good, I thought it was going to be worse.

After applying disable package? what is that?

After a couple of days, minimal packages disabled, Screen brightness average 75% (half the time 50, half at 100%), Resolution at Max, video enhance On, gps on a little, Hotspot on for about an hour, Bluetooth controller/mouse/keyboard on for about an hour. Pretty impressed! I'm going to disable LOTS tomorrow and see how much better I can get. One thing I noticed, I barely had AOD on today, but yesterday had like 8%, hope they can fix that. Nearly 10% of my battery for AOD is CRAZY!

This is my battery life today. Very impressed better than my note 7 and my LG V20.

Ha ha I am not paid. I really didn't think it would be this good. And I don't have the screen turned down about 85%. I turned off some apps from running in the background. My Bluetooth stays on all the time because I use it in my car and to get in my house. That was day 2 let's see how day 3 goes. I have never gotten this good of SOT on any phone. 3 to 5 at the best.
