Post Your Battery Usage Here

Hi, I know it's a little too early but please share how's the battery life coming along..
Screenshots along with other info on wether or not Stamina/Ultra Stamina mode was used. Thanks!

From it's first 100% charge.
1h30m of screen on time, no stamina modes used. Light-medium usage for browsing, facebook, reddit, etc.

That's quite average imho, isn't it? I mean after all the great reviews bout a 2-3 day battery life.. Was it more or less similar on the second charge?
Anyone else gettin better results?

I can't give any quantitative data, but qualitatively battery consumption is just awesome. I'm an ingress player so I'm used in measuring phone batteries in terms of ingress usage time. (screen on, GPS on, data on, moving around continously). The battery goes down sensibly more slowly than my previous phone.

First full charge with Stamina mode activated. Mostly browsing via WLAN, testing GPS, setting up Email etc..

74% used, over 6 hours screen on time over a period of 35 hours.
Very impressive so far. This is the first phone I've used that beats the LG G2 for battery life - and it trounces it!

Hey Ben it's pretty impressive indeed. Any stamina mode or so activated?

Nope. Just as it comes.

That's pretty awesome. Mine currently lasts around 16 hours, with heavy usage (I'll try to get screenshots in the coming days). Mind sharing the settings you're using?

Wow amazing! Do you mind sharing your app usage as well? Thanks!

That was just with general browsing using Chrome & tapatalk, video streaming using Showbox & BBC iplayer and general messing about with the phone. No games.
Auto brightness is on, stamina is turned off, but I do use greenify (non-root mode obviously) to kill apps when I've finished with them.

Amazing battery for me as well. I used the phone HEAVILY today! Lots of browsing and talk time.
There will be no problem getting over 6 hours on screen time.

This includes a lot of music playing as well, and the total is off by about two hours since I rebooted the phone at the AT&T store.
I had stamina mode enabled for some of that, but only the performance part, I disabled the part that turns off networking when sleeping. I honestly can barely tell any difference (except for longer battery life) between having stamina off/on when it's just the performance part, so I tend to leave it on now.

This is my 2nd day, I have 4h screen time and I'm around 45% now right before going to bed. Should easily get me to 2 days of full usage. Which is amazing. This is just the best smartphone ever if you ask me...

Can you give me more details about your settings? Do you use double tap to wake it up?

Here are my stats. I literally tried to use it as much as I could while watching NFL all day. I had a ton of usage today with lots of background processes. This is paired with moto360 all day with stamina mode on with exception of gmail and hangouts. One gmail account and exchange for work.
Forgot to mention I also have Acdisplay - came from a motox and can't live without this function now

Two days so far using it from 100 to basically zero.
Not as impress as I thought I would be. Does this seem normal to you guys?
No stamina mode activated because I wanted to see how long it could last alone. I was really hoping for the "2 day" battery life the reviews were raving about.
Think it may get better after a few more days?
Day 1:
Day 2:
Any suggestions would be appreciated!

Of course. I have double tap to wake on. BT and LTE are disabled unless I need it. Wifi/3G always on. Brightness is at about 30% with ambient sensor on.
Lost 3% over night, but I had a battery drainer app trying to access location all night! And I also really like, in battery stats display and cell standby are on the top. With my Samsung Android system/OS always was on top and it drove me crazy
Btw I'll post stats after another few cycles. This is just a first impression kinda thing with alot of usage time while setting up the phone.

Turned phone into stamina mode before going sleep with 37% remaining. T2w on. WiFi off.
Woke up 8 & half hours later and it dropped only 1%.
This phone is legend in standby mode. Bonkers

Does tap2wake supposedly increase battery drain?
I know it does on phones not designed for it but I figured phones designed for it would have a special kernel or something to reduce drain to normal levels...

Early report of Nexus 6 battery performance : Almost 6 hours screen on time!

What do you think???
With not so good cell reception (as he said) and so many wake-locks, I think it's pretty good!

Now lets see how the battery handles while playing Ingress!

I would be very happy with this if it is typical usage!

If I can actually get anywhere near this I will be very Happy.

Not as good as I was hoping, but still reasonable. That's right around what I've been averaging with my Moto X.

Not good at all.

The wake locks are horrible!
Sent from my Nexus 5 using XDA Free mobile app

I think that is looking decent, with 13% of the battery used being on 'Cell standby' it is clear that reception was not good during the day. On my nexus 5 when cell reception is good Cell standby barely registers on the list. Max of 5% usually. So would we be looking at 6.5 hours screen time if reception is good? Also no indication that battery saving has been used or not (doesn't look like it is, on the screenshots as the notification/nav bar are not orange). Or what screen brightness set.
Who knows. It is all guessing until more reviews are out.

Just what I was thinking
Sent from my Nexus 7

Yes, same with me. On my Nexus 5 with quite good reception the "mobile standby" is less than 5%.
With that in mind, we will have more than this.
And see those wake-locks, horrible.
Probably some apps, services, or accounts need to be properly setup and configured.
More battery life from that.
And for more extreme, we can use darker theme
So, I am OK with this early report, it's a GOOD BASE!

It's a great start. I'm sure we'll have them up to 10 hours SOT with tweaks in no time.

That is mush better then my Note 3... hope I can get this divce sone..

I'm seeing similar wakelocks on my nexus 5 with the last preview. The one before it had much better battery life, at least for me. I think kitkit has better battery life than lpx19D. so much for improved battery savings in 5.0.

Yeah me too. My N5 was charged fully yesterday morning and it just sat at my house untouched all day, and by the time I went to bed it was at 75%, which is pathetic. That's the last dev preview. On KK, it still would have been at 100%, or at worst 99%. I didn't investigate what was causing it, but that was bone stock without a single app installed. It shouldn't be like that. Hopefully the final version won't have that issue.

im not impressed. my G3 can easily handle 6 hours of screen time. But its tweaked to hell. Im curious to see the N6 with tweaks. also, does anyone know what screen brightness was set to?

This.. Battery usage is going to vary greatly by different users that's why I personally could not care less about anyone's battery usage findings other than my own.

Yes it will but it is also very nice to know about what to expect ... this should get just about the same battery life as the note 4 ...give or take 30 minutes

I agree but some people take these findings to heart and if the battery doesn't live up to their expectations they have an aneurysm.

Coming from Sony z2 and im bit dissapointed about the S7E Battery Life

Hello,
First i have to say i really like that Phone looks and feels very nice, changed a bit the ui and rly like it actually but...
The Battery Performance is very poor between a z2 and a S7e,
sure i know better screen bigger/faster cooler but when i see my old z2 can handle 2 (40 to 50 hours) days without charging and i get 400mah bigger battery in a s7e and only get around 20-24h from it thats very poor.
I hope they get something like the Stamina mode from Sony which is learning what you do on your phone to safe more battery, actually the Power saving mode gives me 1 more hour...
this phone is 2 years old now and perform so much better in battery stats thats just unbelievable.

That's why I always carry a 10000mah portable battery charger. No bigger then the phone do it's not a big issue to put in my pocket. I went 14 hours 27 minutes yesterday and that was down to 11%. I'm also a very heavy user tho. I stream, Facebook, text, kik, internet, watch movies, etc constantly. So to me that's actually not a bad battery. Came from the s5 and I was only getting 9 hours max on that. So this is fantastic battery life to me.

i never need to carry something extra on my z2 and i would say im a "normal" user fb a bit emails whats app etc i dont play on smartphones nothing. and compared to my old z2 when i go to bed i had around 40-60% battery left actually i have around 10-20% left on the s7e... i think something is wrong with the battery/software or something.

Battery life seems okay to me. Idle overnight for 7.5 hours is only 1% drain...

I do believe than an update from Samsung will improve the battery on the Snapdragon 820 edition. It's impossible for such discrepancy between Snapdraon and Exynos. On the other hand, it may be that Qualcomm is just behind with their efficiency and people are just not believing it yet.

I get 7-8 hours SOT.

I got 30hrs runtime and 11hrs SOT and am now on track to get almost 3 days runtime and 9hrs SOT. I'm not disappointed. Screenshots are in the post your battery life thread. I'm on my z2 tablet now so I can't post them. SD820 on Verizon BTW.

Something is obviously draining your battery. I really don't see why anyone complains about battery life of any phone the first week they have the phone. Most people never put the phone down. I got my S7 Edge the first day people got them with T-Mobile so I think two weeks now. I'm a power user and killed the battery once at like 8pm after taking it off the charger at 7am. I had the Sony z1 and returned it since battery life sucked.

I can't post my Gsam stats on the mobile xda app, but I am at 42% battery life left with 5 hours and 11 minutes of active time over the course of 9 Hours. Very heavy usage those 5 Hours btw. GearVR for 20-25 mins, YouTube for an hour and Spotify both to and from my work. With the occasional Web browsing.
Damn good for me.
I want to point out I disabled the majority of the bloatware with package disabler though.

I've moved from an Xperia Z3 and i find the battery life to be much, much better. No complaints here.

Ok this morning i get a popup about some apps moved into power saving mode now.
atm im coming home and get 70% batter left, WOW!
so far it says around 40h lifetime of the battery i think you are right guys i should give the phone a bit more time....
btw im on the european version of the s7e i think thats the exynos version right?

battery life

Can anyone with >4 hours sot post screenshots of their battery life? I'm only trending at 3.5 and the only problematic things are Android system and Android os. Already used 250mah after 3 hours off the charger. Google now is turned off and used PDP already but not on system apps

Same here....on snapdrag...

Honestly my battery life is pretty add. Back on the s7 edge during build 4 of the night beta my standby time was incredible. It stayed on 100 percent for 2 hours (although I did use it for about 15 minutes thought the 2 hours) and I expected the same with this phone even though it has a smaller battery. But I can't even squeeze out 11 hours and that's with PDP (disabling all bloat and even bixby and some other small things). I'm considering a factory reset to see if that helps

Um..... My battery life on the s8 plus is the best I've ever had, on any device, with or without a custom rom. The stand by I get is incredible and screen time is always over five hours.

Already got almost 5 hours 40 min SOT and still have 40% battery left.

Yes mate! It can kill your battery very fast. I've lost 20% battery in an hour after leaving my phone in a gym locker with very poor reception with my S7 Edge. The worse the signal is, the harder that phone is working to stay connected. As a consequence, you get huge battery drain in areas with poor reception no matter which brand of phone you use.

I have to say battery life's been very good. Get almost 6 hours sot everyday. T mobile s8 here.
Sent from my SM-G925T using Tapatalk

I also have been getting 6+ hours so since I got mine this past Thursday. Just yesterday I got 7.5 hours sot over a 28 hours off the charger period. It's pretty damn good.
AOD is off. Turned off wifi and Bluetooth scanning.
Don't have bixby setup or enabled.
No disabled apps.
Have the S8+ btw

AOD is the killer - I probably hover around 5-6 hrs SOT with AOD enabled, 6+ hours easily with AOD disabled.

On my second charge I got just over 6 hours. I have the Canadian model which comes with Snapdragon. I have it set to WQHD+, AOD on, 50% brightness, changed a few things in settings, and use Package Disabler Pro to disable things I don't use. Its quite hard for me to drain the battery on this phone compared to the Note 5 I had.

Battery is better than my note 5.

I charged phone two times now every time sot at 5:30 hours with 15% left

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 S21 / S21+ / S21 Ultra before depleting the battery.
Then, drop a comment if you have anything to add!

Pretty damn average on S21 128GB Exynos version. Accubattery says max 6h on charged battery and it's pretty in line with my experience. Charged in the evening (around 19:00) and unplugged, I could only do 4 hours SOT before it died around 17:00 the next day.

I'm on 2.5h SOT. Same setup on p30 pro was giving me 7h of course it was without 5g and no 120hz but still it's a huge difference... let's see how it evolves

Previously I smartswitched and set everything up. I factory resetted the phone, SOT did not seem to get much better than previously reported but I think idle drain is a little better. I don't, however, have all apps set up yet and also changed Messenger to Lite, uninstalled facebook.

Battery life is poor on mine (Exynos) : around 2.5h SoT after a day of use, mostly in WiFi. I actually can't use it for a day even though I try to save as much battery as possible.
Initially migrated through SmartSwitch, I did a factory reset without this migration and still have poor battery life after 9 days of use.
I'm really considering returning the phone.

It's definitely not as good as my previous two or three devices. Especially my last one. But that's not a fair comparison. Most people don't own those or even know about them (Chinese imports - flagship chips with high refresh rate displays too). I've only owned this for just over a couple days and idle drain overnight is too high. Actual SOT is average. Not terrible or awesome. Just about acceptable. My concern is, how it will hold up in the one year or more life cycle of my ownership, if this is its performance four days into owning it.

The following are On all the time:
WiFi
Mobile Data
Bluetooth
Location
Sync
NFC
Power Saving Mode.
I dont manually put apps in deep sleep, i just leave that to the system to decide.

120hz refresh rate
Power save mode off
20% battery left, battery still shows 3h50min left unfortunately have to recharge.

I noticed a massive improvement in battery life on my S21 when setting a Bixby routine to automatically turn off mobile data and location services when connected to known wifi networks.
You can also set a routine for auto rotate to only work when opening certain apps, this will save you further power turning off that sensor until required.
Enable wifi calling under connections if you struggle with mobile signal in any areas where you are connected to wifi. This will assist with less stress on the phones battery searching for a better mobile connection.
Also turn off fast wireless charging in more battery settings if you do not make use of wireless charging.
My standby battery drain with the above settings is now nearly non existent.

Improvement in battery life after August update on S21

Using battery saving mode, since I already use 60hz (to save 15%) and already put WhatsApp and Telegram in sleep mode (and many others in deep sleep). I still get push from IM.
I don't have seen any problem and got much more SoT then shown here.
Soon I post a full battery only print.
