    I think the roaming affects battery life...
    I mentioned this on my first post about the issue, I also mentioned about a similar issue another user was having last year while using the Galaxy S7. Problem is that some people on this thread have mentioned that it shouldn't affect battery while others like me think it does. I may understand that some phones have different radios and behaves different but it's as much a fact as it can be than being on Roaming have a huge impact on battery life.

    BUT, take a look at a couple of articles about the issue:

    Okay maybe you guys are right. Because I just bought a brand new s8+, turned off most battery draining feature, and today I still didn't make it past 4 hours of SoT!!

    So we can discard the deffectuous phone theory. And we can add that to the list of so many other things I tried and didn't work so far.

    So tomorrow I will try to use the phone all day with my wife's SIM card which is local. Let's see if roaming was the problem.

    Will report soon !
    I mean nothing else you are doing is out of the ordinary. I don't recall if you ever posted a screen shot of the apps that are using the battery to see if anything is drawing battery?

    Ok, here is something interesting. I observed that the last three screenshot posted from peppythetruth, Anthony Mclean all have an SOT of 7 hours and 5 minutes. To achieve this SOT, the battery consumption is different for the three of them. One of them used 1200mah, another one used 1400mah and a last one used 1800mah. I assume this difference is due to different screen settings such as brightness or resolution.
    So I decided to go check out my own battery consumption for the screen. At 10% battery, I used 740mah of my battery for 3h37 SOT. If you do the maths, its not excessive. Alll you need to do is double is to see that with 1400mah i would have gotten 7hrs SOT just like everyone else. My problem is that i did not have those extra Mah to use because they were wasted somewhere else.

    So my goal is to know where the rest of my 3500mah battery went ! Why do you three get to spend 1400 mah of your battery on the screen, and I only get half of that !
    I took details screenshot of all the tabs in the battery section, and I am hoping that one of you will be able to compare, and maybe spot a diffenrence, so I can have a better indication as to what I am doing wrong.....

    Here they are. Anything abnormal?

    @erasat, I know you did, but remember, after you said that I tried to use my phone for a full day on airplane mode + wifi but i just got 4h30 instead of 4hrs of SOT. So I assumed this wasn't the issue.

    I ll try today or tomorrow the local sim card just because im out of options, but im not too hopeful.

    Last idea I had after that is ti delete the app I use the most (instagram) and see if the use of it (and especially the fact that i turn on my screen a millions time a day to check my notifications for a minute) affects my battery life so much.

    Almost a month later and I am still getting between 6.5 and almost 8 hours SOT consistently on my S8+ on T-Mobile.
    When I work from home on WiFi all day I can get 8 hours SOT easily.
    At work where the signal is horrible i get 6 SOT.

    Man its hard to realize, But the better the signal, the faster the phone works and it don't work as hard.
    Especially if your in 4G LTE.

    So I got a local SIM card to figure once and for all if everything that's happening is caused by the roaming + bad signal. Result: nothing changed ! I'm 50% down and only 1h38 of SoT! I knew this wasn't the problem.
    And since I've tried pretty much everything that all of us could imagine to improve my battery life, then only conclusion I have left is that all of you who are reporting 8 hrs + are paid by Samsung for your posts. And I would like to receive a piece of the most money to compensate me for the time 8 wasted !

    (Just kidding of course, but I feel like crying and that's the truth)

    Maybe you just need to go to another phone. You aren't having good luck with the battery on the S 8 and its causing you to have breakdowns. I haven't been in this post in weeks and you're still having the same issue.

    Problem is that he has mentioned before that he had the same issue with his previous phone so it can't be the S8.

    Exactly. Had the same thing happening to my s7. Half the SoT as you guys claimed !
    One last thing I can think of is that Instagram is draining my battery. I use the app intensely and check it at least a couple of times every hour.

    Maybe I could delete it off my phone to see what happens to my SoT

    I like how my iPhone takes a long time to go from 100% down to 99% when on standby. Although the battery drain on the S8 is not as good, it takes longer to go from 100% to 99% than my S7 edge. I average a little over 5 1/2 hrs sit and I don't use Google now.
    This ^ If left on standby my IP will sit at 100% for ages. I was in meetings all day a week or 2 back and when I returned to my desk just before 5pm it was on 99%!

    I agree with Sweety Pie,
    Turn it it and check to see if you like the Moto or LG or Pixel flagships. IF not, get a bridge phone...a cheap one that can get you to Christmas. Then, you can decide on Pixel 2 or wait for S9. The S8 is not working for you and you will adapt, but you will not be real happy if you are charging every day to use.

    Instagram = Battery Killer. Is there a way where you can set it so it does not push notifications?

    Sounds like a use case... a mix between the way you use the phones and signal strength. My S8+ is WAY better than my S7 Edge ever was. Also might be the difference between Snap Dragon VS Exynos.

    If you long press the app you can put it to sleep and it will only update when you open it again. Pain to do that each time though.

    You can also go in here and optimize an app. Clock on the app and then click on the save power icon.

    If instagram (or any app) was the culprit you would have known already. It would have popped up in the battery usage stats, right?

    Not sure about Exynos, Snapdragon point. It can't be so drastic anyway, right? I agree on the use case point though. We all use our phones differently. I use the Exynos S8+ and i consistently get 10hrs usage over 24hrs between charges. SOT isn't my thing as I use the phone to make calls as well! Attached stats will show that even with active usage, battery drain is just above 4% an hour.

    Most of em dont use the phone to make calls ☺️
    Just don't go only by the SOT, there are many other things that consume phone resources and hence impact battery life. On continuous use the S8 + can easily top the endurance game.
