Newly bought S8 and a 4.5h battery life. Is is normal?

So I got my GS8 yesterday and this is the battery life I get with:
AOD off
No battery saving profile
Wifi on all the time
4G network but no data
Automatic brightness
No gaming, about an hour of video playback
Since I can't share outside links I'll just write the info here: (From 100% to 3%)
Last charged: 10h ago
Screen on time: 4 hours and 30 minutes (812mAh)
Android System: CPU total: 3 hours and 11 minutes (312mAh)
This is not even close to what I expected, do you think this is normal?

Normal. It's happened with both my S8 and my G6. Your battery life will get better in 3-5 days. Android is setting stuff up and optimizing battery life behind the scenes.

You bought it yesterday. Give it time to settle.
Also, turn off automatic Samsung cloud backup, it's on by default.

How much better are we talking about? Like what would be my screen-on time on average?

I am 45% with 4 hours SOT. But I have days like yours with 4 hours SOT at end of day... It depends on how you use it.
Also depends if you debloat it or not (no root required)

What did you expect from a 3000mah battery? It all depends how you use the phone, i can empty the battery in an hour if I want.
4.5h is more than respectable, if you want more lower the brightness and use a black theme.

I expected the sot other users (like people from this forum) get. This battery life I got is bkarely better than that of my 3-year-old Xperia Z1!
-----------------------------------
Another question guys. Is a 6% drain over 7 hours of being idle normal? Wifi on and AOD off.

It pretty much. Also depend on how many apps you installed. If you dont want it run much, add it to smart manager sleep list. My idle about 3hrs/1% man. This is my battery current round and apps list. About 10% wasted battery because I did clear davikcache a few times

This should be normal. with AOD on, my phone takes about 2% per hour, but when browsing webpages, every 1.5 hours costs about 10% of power, watching videos should take more. also, the 1080p and 2k resolution have notable differences. so it seems that the white-background screen cuts down most of battery life, i think.

For an hour of browsing, mine decreases by 15-20 percent! (On wifi and auto brightness)

hmm, i turned my phone as power-saving as possible - brightness is less than half of the bar, suspended all background apps, and FHD resolution. also, after some days of usage, the system should be able to auto balance the power consumption by sleeping some unused apps and some Samsung's system services maybe. so i don't think this is an issue.

Dont believe every sot someone posts here, i've seen a few 8 or 9 hour sot's but i'll bet the brightness was as dim as can be and they used a black theme. Or they were probably reading a book on the phone which uses no cpu at all or using the battery saving feature.
Your z1 also had a 3000mah battery, yet it had a smaller/dimmer screen, lower resolution, less ram, much slower cpu/gpu. How can you be complaining?

yeah, you're right, the AMOLED screen with high brightness and white color is the real battery killer. also BTW, does the 'sot' mean 'screen-on time'? sorry for my bad English...

Yup screen on time

4.5h is more than enough ! I am coming from a S6E+ it used to give me 2h SOT MAX ! Hated my life with it.

Do you plat Pokemon Go? I find a lot of people I see complaining about battery do, that game is very poorly optimized for battery consumption.

And thanks everybody for posting your opinion. It really helped me!

It's more normal than not.

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 before depleting the battery.

Battery doesn't drain that much, but I've only tested it for a day so far so I may update this in the future

Manage all apps automatically & smart display
5:48 @ 04% ~ 3.63 minutes to drain 1%
4:08 @ 18% ~ 3.02
2:19 @ 53% ~ 2.96
3:51 @ 29% ~ 3.25
4:29 @ 17% ~ 3.24
Same as above then towards the end of the day switched to 720p & auto manage apps off
5:11 @ 21% ~ 3.93
720p & auto manage apps off
7:14 @ 11% ~ 4.88
I think this is more because of the aggressive ram management when manage all apps is on, and what seems to be a bug with smart display. Restarting apps so many times must drain battery. I will try tomorrow at QHD+ and see the SOT
Also worth noting I do not game, I listen to a lot of music (most of the working day) and stream YouTube to and from work I have over 100 installed apps and 6 messaging apps which I switch to frequently. I have news apps that refresh every hour on data or mobile.
standby drain seems a lot over night about 2x the mah than the OnePlus 6 that I have

Barely need to look for a charger thru out the day

Amazing .

Is yours a Boe or LG screen?
QUOTE=Darkat70;78334851]Amazing .[/QUOTE]

Mine is a BOE screen, 18B02.
Pretty awesome to get that SOT, with 43% battery left. I used my GPS for 30 minutes, watched about 20 minutes of YouTube, 30 minutes of Slotomania game.
On standby I lose about 5% battery in 7 hours or so.

Agreed. I am absolutely loving the battery life on this thing, it insane how much heavy usage 1 Charge cycle can take.
I average around 7-8hours SOT, sometimes 9hours and that's with the screen set to 60% Brightness. Absolutely insane, and it just keeps chugging along.

SOT on LG panel. Truly amazing at more than 6 hours with 40% juice left.

How you get like 8h-9h sot? Usually i have 5.30

i have 3h... how is possible? xD

Hi I get about 6 hours ost is that good.? I have brightness on about 90% and WiFi on at all times I have seen ppl get 7-8 hours ost should I keep manage apps automatically on or turn it off any advice appreciated guys

This bad boy is killing all phones when it comes to battery life..

Here are my stats.
Today was a heavy use day so I only got just over a day of use. I usually get about 2 days before needing to charge. So either one day at 9h SoT or two days at 7h30 SoT, I guess it depends which apps I use too. I try to charge above 5% and stop at 95%.
WQHD+, auto manage apps on, dark theme everywhere I can, never have both wifi and 4G on at the same time and am in Airplane mode during the night to limit battery drain (very effective, I never lose more than 3-5%).
I do a lot of web browsing, a bit of gaming and YouTube, and Facebook/Messenger are probably running in the background and are used a lot.
I rarely have brightness above 50%, except for videos. I mostly stay between 15 and 50%.
System update .153

I noticed that my battery life isn't as good as it was with ly first mate 20 pro that was equipped with an LG display. Since i got my replacement using a BOE screen, battery drains faster. I still manage to get 6/7h of SOT so i'm not complaining but it was better before

BOE screen here, power save mode, 1080p forced resolution gives me 12+ hrs SOT.
Same settings on S7Edge got me 8 hrs...but then again, that battery is 3 years old, therefore around 82% capacity.
Happy camper so far.

The stats i gave were achieved with the exact same settings as i used with the LG equipped one. I used to have 1/2h more of SOT

Battery life is just too good and with the new update 152 makes it even better S

Nice results! What version were you on before? I'm still on .146

On latest 171.. did not notice anything still amazing since day 1..

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 Huawei P30 Pro before depleting the battery.

I am getting 9-10hours SOT consistently on the P30 Pro, mine is the 256GB 8GB RAM version, and I have been thoroughly enjoying the camera and battery life.

8 but i have another 20% battery so i can make it 10.

I am definitively not getting that much.
Right now I have 29% battery left with 4,5 h of SOT and 1,5 hours of calls, couple of pictures taken yesterday. BT was on the whole time connected to my watch GT, Wifi on, 4G on.
I just updated yesterday afternoon to version 124. Maybe it improves over time.

What's the best way to drain less battery? Keep WiFi on or Mobile Data on or both at the same time?

With a normal use (from 5:45 to 17:45) with
auto brightness, 2 wearable connected, 4h of music via BT, GPS always on, 1h of voice call... I made 9h of SOT within 48 hours (with a single charge)

I have a problem. The battery menu can not be more than 6h SOT. I do not know where I'm wrong. can he help?

I have the same problem. I think since the update the battery drain is insanely fast.. No rogue apps, just fb, messenger, and mostly of them are put to manual mode.. What is going on, pls help. Also it can barely go through 24h without charging, mostly 5h on screen time max..

Coming from moto z play battery on p30 pro is a sad joke. 6-7h SOT charged on the morning, empty at the evening, with screen dimmed as much as i can, either by app that lowers auto brightness by 50%, or lowering it manualy. I have read reviews that stated great battery life, so either they were misleading or maybe i should turn it to the service. 124 software, but it wasn't any better before the update.

Hmm gsam :/

Sounds like a faulty device. You should be getting 8 hours and over for SOT

Good
11 hours SoT. Auto brightness. Pretty goood. :good:

But was auto brightness at the minimum value, possible only in darkness?

How the hell do you get 11h on screen time with one charge????

Either with screen dimmed so it's visible only in total darkness + wifi internet... or in fact some people have outstanding battery and other got horrible.

I always end my day with 50-60% left and 4-5hrs of sot. Auto brightness and mobile data.

The brightness was average 50%. It has to be mentioned that the battery is hugly affected which apps that are used. As you can see from my post i used reddit and youtube a lot when i got 11 hours SoT.
I have experienced 6-11 hours SoT. So 7 hours is not bad... It all depends on which apps that are used.

I have charged it this morning, now It has past 2h and 45 min since the charging, screen on time 52 min and 88% left. It says only 20h are left before the battery runs out.

OnePlus 7T, unlike the predecessor OnePlus 7, is
confirmed to have 90Hz refresh rate.
Hence, whoever is going to post SOT, do not forget to mention refresh rate used (90/60 Hz), screen resolution, "tweaks" and "measures" taken in settings etc. Also show full screenshots. Thanks.

GSMArena has given an endurance rating of only 84 hrs (90hz) & 89 hrs (60hz) which are not that great considering OP7 which had 102 hrs. I cant understand even at 60hz why so much difference compared to its predecessor?

Higher clock frequencies

So is there way to underclock to 855 rates and get about 100+ hour battery endurance ? It's big hearthbreak for me these battery stats, still better than my HTC U11, I get around 3.5-4 hours screen on time. Device 2 years old.

Not sure it'll compare to my OnePlus 5 record
Of 14 hours 40 something minutes in one charge
But I think 10 hours should be possible.
Here's my old thread, I always requested proof, app list, battery stats and installed ROM.

No played much, max for 40 mins, in that 6 hrs.

brightness?
Since this screen is a 1000 nit, could it be the auto brightness settings are up way to high, and thus much higher battery use. As far as i know, the clocks on the 855+ are a result of binning, so same voltage with those clocks, unless that is inaccurate?
watching this vid, with what he says is equalized brightness he manages to get 3+ hours of pubg, along with youtube etc, for 8:46 of SOT. Now as i have a 6T this is pretty appealing, but reading a lot of reviews, it seems 5.5 to 6 hours is the average and i wonder is that because of having brightness wayyy up, if the slider isnt balanced, or rather linear. 50% could be 500nit, which is max brightness on a lot of other screens. Thats 45nits brighter than max on a 6T for example. Just trying to sort out the discrepancy, between this gaming test, and what reviewers are getting. I cant imaging 4g modem is that big of a difference.
—------------Update-------------
In terms of battery life, the 7T put in 8 hours and 47 minutes of work in Tom's Guide's custom battery test, where phones endlessly cycle through websites at 150 nits of screen brightness until they run out of juice. Decent though that is, that's not only worse than the OnePlus 7 Pro (9:31); it pales significantly when compared to the iPhone 11 (11:20) and Samsung's Galaxy S10 Plus (12:35).

this from Tom's hardware seems to rule out over bright theory as they control nits to 150, but that seems crazy compared to the gaming vid we see above that shows a mere 45 mins less while streaming video and 3+ hours of pubg. It can't possibly be as demanding to refresh a web page at 150 nits. Judging by the video as well brightness looked easily over that level. So guess we'll have to wait for the IRL user reports

I am really finding very minimal difference in haptic motor between the OnePlus 6T(my friend's) and my 7T. But I can say the loudspeaker is really good on the OnePlus 7T.

Update day 2:
I am totally satisfied with the battery backup. I am a above average user but not a gamer.
The below stats were 80% on WiFi and remaining on 4g. Have turned off ambient display since I am not a fan of it.

Thanks for posting that, what was the average screen brightness, ballparked if you dont have gsam style breakdown? Those numbers look better than the 7 pro! This usage mirror's my own, in that i dont do a lot of high cpu/gpu intensive work on my phone, aside a quick few photo/vid edits maybe. No gaming, so overall SOT for emails, msging is important. 8 hours bests what ive got on my 6T on auto brightness.

I had a Oneplus 3 since october 2016 and I did not realised how bad the battery was. During the last 2 years I had 2h30 of sot MAX, mosty 2h.
With the Oneplus Nord, after the first charge I got 4h30 of sot (36 hours of usage) and still 21% battery left.
I don't game, mostly web browsing.

This has me a bit worried. I have had a Huawei mate 20 and a Xiaomi mij 9t pro that got me 6 to 7 hours easily... And those had 4000 mAh.

This proves everything is relative. It is more than enough for me.
Don't forget It was only the first cycle so I cannot conclude anything yet.

Not to bad after 4 day's actually. 5.5 hours SOT and 33% left. Most of the time spend on WiFi though.

9h
Just web browsing. Little youtube , 30 minutes or so. Wifi. Brightness auto.

Update
Well , there it is.

Battery is great. Period.

Battery is great. Usually I get 7-8 of sot. Also the charging is ridiculously fast for me as I switched from a 4 year old phone with just a 5 watt charger.

Also getting 7-8 hours screen time. impressed

Nice how are your settings and how much standby time ?

Check on lte or 5g only and show the graphs .
Battery drainage is not just a nord domain.

Very satisfied

I only charged twice so far, but both times I barely got over 6 hours SOT. Using 60hz, on WiFi, mostly just browsing web, no gaming.

Well maybe it is so high because I did not used the phone that much then and it was new , not so many apps instaled .
Now a get max 8 hours .
So , it just hapend I guess.
One HIT wonder like. ?

I am barely getting 4-5 hours of SoT. Is there something that I need to do to boost up my battery life?

When I first got the phone battery life was just ok 4 hrs sot. After 5 days its improved by quite a bit including the latest September update.
Am on 90hz all the time. Blocked all Facebook. So far its ok. Would have been great if it had a slightly bigger battery.

I will get an 6 or 7 hrs screen on time on 90hz,
In this picture iam using continues hotspot thats why its low
