    As others have pointed out, sometimes it's because of a person's signal strength
    I refuse to accept that and signal makes a difference between 8 hours sot and 3h30.
    And my signal is not that bad. 3-4 bars at work and 4-5 bars at home. And I'm on WiFi most of the time.

    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 have no idea. I'm at 38% today and 4.5 hours of OST. Should work out to about
    7+ hours. I'm using web browsing and YouTube all day, continously, with 4GLTE. No WiFi. Now yes that less then 9-10 but I'm only using 4glte, dipping from 4-3 bars, and I'm outside in the bright sun so it's at full brightness. No phone calls made really either, just messaging. My lowest yet, but I'm dipping between signal strength today because I'm all over. Still great life.

    I easily get 9 hours OST, and over 20 hours total, with WiFi mixed in.

    I'm not lying to you for chirst sake. I was one of those guys who never understand how people were getting 7 hours on some of the older phones. So I'm not that guy. I'm telling you the truth. I've owned a lot of phones.

    And why the hell would I lie? Are you guys crazy? My s6 edge battery sucked. My s7 edge was OK in the beginning, but actually dam good after the software update for some reason. And this is the best I've gotten. I'm. Not some fan boy.

    Well, I'm at 28% battery and only 3 hours sot. So far behind you. And the worst is that I haven't used my phone as heavily as you today. So frustrating.

    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.
    I regularly get 6hrs plus on my S8+. My screen brightness is normally around 25 percent indoors, and fairly high outdoors. Auto brightness on. Locations services and sync all on. Typically stream 30mins of Netflix at lunch at work. And I'm on LTE data all day. I've owned many phones over the year's. This phone gives me best battery life by far. Beating out my previous champ, the Note 4 by a good margin.

    Forgot to mention, I also set screen res to QHD from day one. Using Snapdragon variant on T-Mobile

    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.
    Right, I had an S7 edge and could never get anything near what I'm getting. It had decent battery life, but now I'm getting amazing battery life.
    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.
    I had mixed usage yesterday, 15 hours and 8.5 of that was SOT. Still had 10% left when I went to bed. That was a majority spent on WiFi. I have the screenshots if you want to see them. I've never gotten numbers like that before or any phone and I've been on the forums in the past wondering why I couldn't get numbers like that. I dunno, sorry your results weren't the same. What you're describing in your post is what I got with the S7 edge.
    Well, I'm at 28% battery and only 3 hours sot. So far behind you. And the worst is that I haven't used my phone as heavily as you today. So frustrating.

    It looks like you're roaming. Are you sure you have good signal? That will kill battery in a heartbeat.

    Yeah. Signal shows roaming with very poor signal. That'll destroy batt life

    So far, we are seeing S8 and especially S8 Plus users saying their battery life is really good. There are exceptions though...
    1. Some folks when we look at their screen shots...we are left to wonder how much they are really using the phone, the itnernet, apps, etc.
    2. Some folks are turning on the battery saving tools, others are not and still getting great times...so we are left to wonder about that.
    3. Some folks...and it appears to be more S8 then S8 plus are getting some really BAD battery times that are not consistent with other users, leaving us to wonder if their is a signal issue or something else.

    For those S8 and S8 plus users...please continue to log your stats and particulary add contenxt..."this is how I used it" so we can get a better feel...Much appreciated!
    P.S. Please do not forget to say if you are rocking an S8 or and S8 Plus....very frustrating when you do not say!

    My usage is mostly Facebook and chrome. Not using battery saver. All locations service's, sync, and Google now enabled. Screen set to QHD. S8+ on T-Mobile. On LTE most of the day or all day with fair to good signal. 6hours or more SoT. Note that when I used my LG V10 with same apps and same way I struggled to get 2hrs.

    Not really going to track this much any more this is great for a work day. Not much screen time like 45 minutes. But you know I was working for a change.... Lol

    I did put it in the Qii car charger on the way home but I streamed YouTube and Navigated using split screen. (Don't worry it was just a podcast I didn't really watch it.)

    This is what I got last night. No I don't always get this. This is a first (probably a fluke). I usually average over 5 1/2 hrs SOT.

    I didn't use phone enough to see it through to the end, but on one day I had nearly 4hrs SoT and 45 percent battery left. Had the pattern continued I would have been between 7 and 8hrs.

    Ok so I keep reading comments about people saying some are hiding things. And using battery saver mode. And lower resolution. And not using apps like YouTube. Blah blah.

    No one is hiding anything. Why the hell would anyone do that? It's getting silly. I honestly could care less about those people at this point. I will however state my settings and usage one last time. Maybe it will help ones that are struggling to get battery life. Idk. Personally I feel bad and I think something is wrong with their phone.

    When I got the phone I let if drain down to 0. And charged to 100. Did that about 3 times. I then charged from 40% as much as possible. I use no saver apps or managers. Only thing I use is CCleaner to clean my phone up every few days. That's it

    I'm running NOVA launcher. One widget on my screen. And a black Samsung theme in the background. I'm also using live wallpaper for my lock screen. Regular for my home screen.

    I have auto brightness on at all times. Sync on at all times. App notifications on at all times. Location off. I am on Verizon 4glte, 3-4 bars throughout the day in the bright sun. At home I'm on WiFi and 4glte on different lighting conditions.

    I don't make a lot of calls. I'm constantly on YouTube, Chrome, tap to talk, and amazon, eBay, etc. Keep multiple chrome tabs open wgejike/while I'm online and keep it open in the background when in YouTube. And vice versa. Facebook use is very minimal. I use messenger though.

    My phone is set to the highest resolution. It's also set to high performance mode which drains the most battery. I stream all my YouTube in the highest resolution available. Like I said I'm constantly watching YouTube and browsing Chrome. Usually 2 hours at a time.

    I'm getting around 9.45-10 hours OST and 20+ hours usage with WiFi. I'm getting about 8.5-9 with WiFi and 4glte mixed in. And I'm getting around 7.5 with just 4glte with 3-4 bars, outside all day. That is a fact. Doubt all you want. I'm not doing anything crazy to get life, and not some fan boy.

    Anyway I've repeatedly shown stats and I'll show them again now. IMO id you're only getting 4-4.5 OST with an s8+, return it because something has to be wrong. This is the best battery performance I've ever had. I wish everyone luck with their battery life. Take care.

    Man your results are CRAZY!!!!
    Here are my results of yesterday. Didn't make it past 4 hours again.
    The day before I had miraculously gotten 5h30 sot so I started to wonder what I had done different.

    Here are the three things I can come up with between the good and the bad battery day.

    Ok the good battery day:
    1. I may have had better signal, but I am not even sure
    2. I used Instagram much much less than usual. It's nomarlly the number one app I use the most
    3. I didn't use Bluetooth to stream my audio book and Spotify to my airpods.

    Besides than, nothing special. Im back with my crappy battery life.

    Few things i need to mention:
    1. Yes I use a foreign SIM card in my phone which means that I am constantly roaming (but it doesn't mean my signal is bad I always have 4 bars up)
    2. My s8+ is an exynos (955f)
    3. I purchased the phone directly on the Samsung website.
    4. I have not upgraded the phone since purchase (I blocked the ota update that came on the day I received it because I wanted to keep the ability to remap my bixby button to whatever I wish)

    Any thoughts as to why I can't get passed 4 hours ??

    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.
    Sorry, but your comment is trash. The iPhone 7 (Plus) has many hardware features, the S8 doesn't have like the dual camera with the amazing portrait mode (the Samsung software emulation can't match this), stereo speakers, the Taptic Engine (pressing the home button feels so much more real on the iPhone), 3DTouch... Also almost every review site on the web has found the iPhone 7 Plus battery to be superior to both the S8 (look at phonearena.com for example). And what's more the iPhone 7 still smokes the S8 in benchmarks and app rotation tests. Yeah, the S8 has the fancy new design and the superior display. But the iPhone 7 is far from being "old tech".

    Well I did watch a heavy usage battery test between those phones, and when Iphone 7+ died, S8+ still had 39% battery. I also watched a speed test. And S8+ won in opening apps, but iphone7+ won in opening games.
