    Unless i'm watching long youtube videos or something worthwhile yes i can barely see a difference anyway tbh(i did hear there's not a huge difference between both resolution battery wise). All in all i mostly use fhd since i can still see my screen outside and in these case i use the performance mode.

    Alright so here's something craxy: after complaining for 8 days of not being able to get over 3h45 of sot, I just had an amazing battery day like my phone had heard me and had gotten offended !

    15 hours of the charger, over 5 hours of sot and with those 9% left I could easily reach 6 hours !
    I haven't done anything different than usual so I can't understand what happened ! But I hope it lasts.
    Auto brightness on, 2 hours of Netflix at 80% brightness, sync on, location on while using the google maps, notification on, qhd screen on, quite a lot of outdoor use! I even used the phone to fly my mavic pro for 20 mins with 100%brigthness! And now I'm going to bed without having charged the phone while normally I must charge it before diner.

    I'm so confused !!!

    Went to Best Buy today and had one of the Samsung guys take a look at my phone. Said something definitely wasn't right. He looked and couldn't find anything that could be causing my pathetic battery life. Re-flashed my software, and if that doesn't work I'm swapping it out for another phone. Had barely over 3 hours of SOT and 25% battery left.

    This is from my first whole day with the S8+. The phone is great did so far on the battery, and normally, I'd experience a lot of drain at work due to the concrete walls, but I switched to AT&T and have better service , so I'm doubly happy.

    I think everyone needs to pay close attention to not just SOT, but other usage on the phone. For example, the nearly 10-hour SOT that was posted earlier here, look at the app usage percent. It is extremely low. Whatever is eating up the active time has to be highly optimized. Also, it is very likely that the brightness of the screen is low. The stuff people post here is grossly misleading. The S8+ has okay battery life for mixed heavy usage, and is nothing to write home about. Plenty of phones out there are better. S8 is probably atrocious.

    Battery life has been great for me on the smaller S8. Currently at 3 hours SoT with 52% battery left. My S7 would be at 30% by now with the same usage. Yesterday got 5.5 hours. I can imagine what it would be like if I got the Plus. I'm very satisfied.
    Yeah I'm getting two to three more hours of SoT with my s8+ than I've ever gotten on any android.

    Battery has been great thus far on my normal S8, I mostly use wifi and data all day at about 60% brightness with a slew of services running including high accuracy GPS and wifi calling on T-Mobile.

    I estimate an average of about 5-5.5 SoT with a day I do a lot of reading I can probably get over 6.

    This is today mixed with some YouTube , Facebooking , Browsing , photos vieeikg and sharing etc.

    Yeah I don't know why it says that cause I've never seen 4 hours sot on my phone. As an example if you look at this screenshot i have 1h45 of sot and I'm half way through the battery. Means I won't pass 3:30/3:45.
    Not sure why it says 4 hours cause that neevr happened to me.
    And anyway 4 hours is pretty crappy compared to the rest of you who get between 6 and 9 hours without turning off all the features of you phone like I have to do.
    Maybe the Exinos processor is not as good as the SnapDrahon this year?

    Here is my Sunday... at home all day on WiFi with cellular on. Indoors on a cloudy day so I had screen at around 30% but with Auto brightness. I was on the phone a lot but on WiFi.
    Amazing battery life in my opinion... even considering that I was on WiFi for all of the data downloading, and the relatively low screen brightness.

    You know, I gave you the benefit of the doubt and I actually pitted my S8+ fast charger against my iPhone 7 Plus on an iPad charger...guess what, charging from 20% to 45%, the S8+ got to 45% while the iPhone got to 42% at the same time. That's a 3% difference only. In the meantime, the iPhone did not even get warm, where as the S8+ was nice and toasty. Even if I extrapolate this to 100%, the S8+ will likely charge to 100% faster than the iPhone 7 Plus, but not by much, maybe a few minutes at best. The iPhone will likely be around 93%-95% charged by the time the S8+ is at 100%. Depending on how much the Samsung fast charging slows down the two might actually end up even closer. So there it is...the whole "iPhone charges slow" is pure crap. It does, if it is using the crappy stock charger. If you are using the iPad charger or another high-current charger, the iPhone can take the charge just fine and charges (in essence) just as fast as any top-end Samsung phone with Adaptive Fast Charge. If you want pictures, I can post those later too.

    Edit: Just a point to note, both phones were not running any apps, had basically the same apps installed, same configuration, and both on Airplane mode. Basically, I equalized them as a user would under normal circumstances. The setup was the same because I use both phones and both need to be configured the same apps-wise.
    What a seriously bad and flawed analysis. There is no comparison between an iPhone and S8 plus. The S8+ blows the doors off in both battery life and battery charging.
    iPhone is trash using old tech and cheap parts.

    Whoever is getting 4 hours of screen time needs to exchange their phone. You've seen my OST posts. Chirst I'm at around 40 mins OST right now, no WiFi, all 4glte online browsing, and I've dropped only 3%. Get your phone checked out if you're not getting at least 7 hours.

    In other words, stop being happy about your battery life. You are incorrect to be happy about your battery life. LOL

    Look I'm no expert on these matters, all I know is that in my typical use on my S7 Edge, the battery lost percentage points at Double the rate that it loses them on my S8 Plus. All your fancy technical explanations will not change the fact that I know for a fact I'm getting nearly double the battery life that I was getting.
    Yeah idk what he's talking about. So what if app usage is low. I'm on my s8+ using YouTube and Chrome with TaptoTalk, and some social media mixed in for most of my OST. YouTube more then chrome. With auto brightness, outside in the light most of the time, sync on, notifications on, using 4glte and WiFi sometimes. With high performance mode ON. I'm getting 8-10 hours OST with 20-30 hours total time. That's the bottom line and that's ridiculous for any phone. I don't have to use 10 apps to prove it. YouTube is one of the most battery draining apps considering I'm watching video, in high resolution, over 4glte. I'm a power user too. I use about 30 gigs a month. So I know what I'm talking about when it comes to battery life.

    And by the way, that app usage is what percent of the battery was drained by the apps you're using. Which basically shows that the phones processor is highly optimized, that's a good thing and doesn't mean you're not using apps.

    This is the best battery I've had in a phone. And I've had a lot. The guy who just posted that is full of it. Or jealous. This phone is ridiculous. I got 40 mins of YouTube last night and my battery drained 3 percent. So you were saying?

    I see dramatically different battery life when I'm at work or when I'm at home on WiFi. It's when I'm on WiFi that battery is ridiculously good. This is today at home all on WiFi. I had just over of 30 minutes SOT and my battery was still at 99%. That blew me away. Here's my stats at 80% now
    That's what I'm talking about. I got 40 mins last night on 4glte and my battery was at 96%.

    The problems is that I use my phone just as you described it, except that I never pass 4 hours of sot. How do you explain that ? Your phone is a super heroe and mine as a defectuous battery ??

    I had my S8+ connected to a strong WiFi signal and I never got more than 5 hours SoT before I returned it, and that was with mixed usage. I am also skeptical of those posting 7-8 hours SoT.

    Besides, SoT is not a very good measurement of battery life. There are many factors that affect battery life, such as signal strength, app usage, background refresh of apps, etc.
