As a test I disabled AOD and it has dramatically improved my stand by time. I've had the phone on for 5 hours and have only lost 5%. I definitely think that was draining my battery more than it should.
Galaxy S8 / S8 + Battery Life Thread

I agree. The radio is killing it. My signal has been **** lately for some reason and I'm only getting 6.5 hours max now without WiFi. Idk what's going on with the signal in my area but I'm usually 4-5 bars. Now I'm 2-3 this past week. And even standby I'm losing like 10% overnight from the radio. When the signal is normal around here I'm getting 8 hours. And 10 with WiFi. If I mix WiFi in I get 9 with WiFi and 4glte.
It looks like this phone has a serious battery drain when it comes to running off just the radio. I could see an update coming and it explains all the battery life issues. It's definitely the issue. 100%. So anyone confused, there's your problem
Ok Michael. I want to believe you on this one. I hope you're right so I have the answer to my problems. The only thing is that even with bad signal, a bad battery day for you is still 2,5hrs of sot more than me on my better day. What is it due to then ! Roaming ? I'll try another WiFi only day to see if I get results this time

You're probably right, which means I get double drain, from bad signal + roaming. The problem is that the other day I used my phone all day on airplane mode + wifi and I still didn't even make it to 5 hours, when some people hear get 6,5 on a bad day
All I know is I'm having serious battery issues with my signal being bad this week.
Thanks Michael. Please continue reporting your progress with this issue.
Yesterday I had 5 hours of SOT while my battery was still at 47%, no idea how I did it. 30% brightness, WiFi on, WQHD+ resolution, could probably easily reach 7+ SOT, but as it was late I went to sleep
One thing I'm confused about is why folks are saying that roaming would drain more battery. Roaming means that you're not connected to your home network, but the signal itself even while roaming is going to be good if you're in a good coverage area. Phone isn't going to search for a signal constantly if you're in a good coverage area. So why is roaming itself an issue?

Here is what I am seeing:
Unfortunately, we have a lot of folks who are not listing if they have an S8 Plus or the standard S8. So it is difficult to tell if problems are based on the model. I would encourage you to start by saying "I am usiing the S8, or S8 Plus" I almost wish I could delete the ones who do not identify their model so I could better see if there is a pattern in the thread....It appears that there are more people identifying as S8 Plus who are having very good battery life. So I am sort of going with that theory for now....It appears that there are issues for both the S8 and the S8 plus for a limited number of users and they dont know why.
I would be interested in any replys to some any of my thoughts below....just to see if I am on track. I am trying to determine if I want the S8 or wait for Pixel 2 (I am not into larger phones, I like the smaller one cause I like throwing in my front pocket and I like using with one hand).
Here are some of my conclusions from reading this thread so far:
1. The phone is a one day phone with an average SOT of 7-8 hours which is actually pretty darn good.
2. The SOT is more in the realm of S8 Plus based on who has self identified. We dont know about the S8 cauwe dont have alot of folks who identified as S8. Doesnt mean its not as good, just abit more inconclusive untill we get more people identifiying S8 standard and SOT and hours.
3. Some folks are getting really good SOTs and some are not. It seems like for the most part with moderate to somewhat heavy usage the phone is making it throught the day with little or no problems with juice to spare. This is true for alot of people. For others its just isn't. So far we are indentifying signal strength. And so far it is comparing to the S7 and S7 edge in terms of battery life....maybe a bit better for many with the S8 Plus.
One other thought for those who are getting poor SOT.....my friend when she got her S7...her battery life was horrible for the first two weeks or so, she came to me, I played with the phone and battery usage went way up. The two things I did was I removed Facebook and there was a setting that at I turned off that ...I think it was allowing to the phone to look for a wi-fi signal...so try those things, it might help!

S8 plus for me. Max SOT I ever got was 4h26mins and that was all day on WiFi with brightness at 35%
Actually i think they are very similar. Same everything except screen size and battery size. So in most cases discussions would pertain to both models. I see your point in this case, for battery usage and stats, that it will be different depending on model. But in most other cases, discussions would apply to both models since they're pretty much the same phone.
Quite odd that over here in android central forums ive already seen couple people ask and mention that there should be two separate forums for the regular size and plus size. On the other hand over at XDA I've seen numerous people request the two separate forums to be merged into one, and question why is there a need for two forums when majority of discussions are the same and apply for both models. They would have to visit two separate forums, and read threads that pretty are the same in both.

I do prefer just one forum for both, it's really a nightmare just browsing 2 forums simply because there can be things posted in one forum and not the other (AKA S7 and S7 edge) and being almost the same phones except the battery and screen size just one forum makes more sense.
What can be done is simply creates another battery thread and then you can easily identify each thread for S8 and S8+.

Is it safe to say that usage of the S8 and S8 Plus is similar to the S7 and S7 Edge....however the 8 Plus might be bit better (for most users)?
If this is true.... another thought is running through my head...how did Pixel 1 and Pixel 1 Plus do? My understanding is that the battery usage for these phones was on par or very similar to the S7 and the S7Edge.... but the Pixel 1 Plus (has better battery life). Point being they were similar...maybe.... slightly longer lasting than the Galaxy S7 series. I am wondering if the Pixel 2 will improve on things substanially from Pixel 1?
It appears S8 Series performance has indeed improved a little from S7 series (particularly the S8 Plus)..but it seems like it depends on the user and the average SOT is better...but still...its a one day charge phone?
Is my analysis pretty close so far as this community can tell?
One other thing...why I am so freaked out about a battery? I dont live in the woods or on a farm!
