Galaxy S8 / S8 + Battery Life Thread

[Arsenio Martins]

Oh my god ! Finally someone with terrible battery life like me ! I thought i was alone in the world but now we're two !!!!

No matter what i do i can't pass 3h30 sot with everything turn off and barely using the phone while every one here claims to get between 6 hours and 9 hours of screen time.

There must be something synching in the background. I set mine to not have any battery optimization and it went from 6+ hours of SOT to 3.5. so something is updating or synching. I'm sure of it.

This would be my dream to actually identify the problem. Any idea how i could figure out what is draining my battery ?
Thanks for your input

Have you tried GSam?

 

[EMGSM]

Facebook App is a battery killer!!!

My thoughts exactly. If it's pre-installed, it's one of the 1st to go for me.

 

[steven Hadjez]

Ok, so i just had a other S**** battery day. Absolutely awful with around 3hours of sot even though i have all locations, haptic feedback and auto brightness off. Its even worse than yesterday.

That being said, i decided to use gsam today to try and identify the problem. Here's the screenshot.

Is it normal that phone radio is so high ? Is this the reason why you guys get over 6hrs sot and i barely get half of that ????

Download GSAM. Let it monitor for a day or two.

Also for those of you that use the Facebook app.... Go into the Facebook app setting and turn off autoplay videos. Not only will it save data but it will also save battery. Why let a video in a stream autoplay if it might not interest you.

For anyone wondering...the Pixel XL charger does fast charge the S8 +.

Looks like bad service, your phone is constantly searching for signal. That's what my phone does when I'm in a bad coverage area. Probably the biggest battery drain of all.

But can this account for 3 hours of sot as opposed to the 6-8 hours everyone in here is getting ?

 

[Arsenio Martins]

Yes it could be. Based on your screenshot you have 4G service but you are also roaming. Which cell provider do you have?

 

[PopFilms]

Are you a heavy user ?

Eh, not really. This was me watching downloaded Xfinity DVR for about a half an hour, listening to podcasts, and checking reddit.

Over the past few days as I've been tinkering with the phone my battery life seems to have gotten much better. As I type this at school my phone is currently at 54% so I'll be able to make it home without whiping out my charger.

It's definitely your problem. What carrier is this?

Check your Mobile Network Settings on Connections and see if you identify there any unusual setting. Also, no, you don't need to turn everything off on this phone, if you are on that point, better go and exchange it for a new one and tell them that the reason is that the battery must be bad.

BUT, even with a brand new phone I'd check for your Mobile Network settings, and if if they are by default, try switching between the options to see if there is an issue with your carrier and the signal/bands that you are actually getting.

I'd advise you to do a full backup with Smart Switch, save everything possible, then do a Full factory reset, set everything back and if it keeps doing the same, ask for an exchange, this phone has a great battery if you are not getting it then you have a rogue app or some kind of other hardware/network problem that you won't be able to fix it by yourself.

Does it meet your needs? if so then you have good battery life.

Yep. It works for me.

When I'm at my dad's, where my service is horrible my phone gets less than half of what it normally does.

 

[amotter]

This is consistent with my own experience. Every metric I've used to measure screen on time shows I'm getting seven to seven and a half hours.

So this is S8 Right...not S8 plus right? Just being sure!!! Also, the Time On..or in the text "on time"....is that referring to....what exactly? IS it the time you turned your phone on? Cause if that is the case I will jsut say "Yiikes"...or is it referring to the amount of time you were actually DOING something and the phone was literally lit up (phone call, texting, video, game, internet, whatever!).

I feel like this battery life is amazing. Very happy with it!!!!
