    I accept this. Every source on the internet seem to say that the signal has a big impact. But then my signal must not be bad at all. If not how do you explain that I did not get better results on day 3, when i toggle airplane mode on to shut every radio signal besides wifi?
    Yeah that doesn't make sense on airplane mode your phone should've given you 24 hours SOT easy

    I haven't charged my S8+ in 13 hours and I still have 50%. Not too shabby.

    Noticeably better than my S7 Edge. Max brightness no bluetooth or wifi general use during the day average about 14-16 hours.

    Well after all those great days my battery got worse. I used to get 40 mins screen time and lose 4 percent. Not I'm losing almost 13 percent with that. My battery life has gone down. From 8-10 hours OST to 7-8 at the most it seems like. Idk wtf is going on

    The thing you don't understand is that iPhone are far better optimise on iOS than any Android is meaning batteries are more efficient and suck less power and they need less powerful processors and less ram than Android phones do. So they still have equally good performance or better than much higher spec android phones. Hence why the iPhone 7 blows the S8 out the water in benchmark tests. Plus their build quality is top notch but yes they're still overpriced. Yo compare it with a midrange Android like Blu is just being stupid. I think you need to be little more open minded?
    I used iphones before but performance does not blow minds at all it performs well in single cores applications but since it has a dual core the muti core tests get trumped all over by the s8 + yes iphones are good for lazy people ie: those who don't wanna take 30 mins and set a device up like they want.battery efficiency is always dependent on your usage which is true for both platforms. In the end it's more because apple has a bigger ecosystem and is more well known brand people these days tend to stick with what they know too apple is riding on their fame atm they have nothing that android doesn't and btw dat 3d touch is the biggest gimmick of recent years imo.

    Looks better today again. Must have had weak signal the other day. I'm on 4glte, high performance mode, auto brightness, sync and notifications on, and location off. All on screen time is chrome and YouTube today. I'm on pace for about 8:45 OST. So idk what was going in yesterday. Total time seems down though. I think my stand by time isn't as good as it was. That's the only issue.

    Take it off auto Brightness.
    Go on the apps to battery and git rid of everything that is drawing battery.

    Install Greenify and turn it on.

    Nah ik good. I donr use grenify. I've had nothing but problems honestly with stuff like that. Appreciate the advice but I'm getting 7-10 hours OST. I'm fine. If it dips below 7 then maybe I'll turn off auto brightness.

    Interesting to see the euphoria wearing off. I think some individuals that were seeing (what would qualify for) extreme battery life performance are now recognizing that the devices are settling into a pattern that is not nearly as good as what was being shown originally.

    READ THIS SOME OF YOU WILL REALLY LIKE IT !!!!

    Ok so here is something interesting. I am in the middle of an experiment to find out the reason why everyone in here gets an average of 8 hours SOT and I barely get half go that on my s8+. There is something dragon the battery on my phone without me noticing it and I need to find out out. To that effect, I started a "discard" approach, why I try every suggestion I am getting from you guys one by one to see which will affect my battery life. Here is where I stand so far:

    - On day 1, I toggled off all the battery intensive features that you guys mentioned such as Wifi, bluetooth, locations, auto brightness. I set the luminosity of the phone at a fixed 30% throughout the entre day. But unfotunately the results were the same: a disappointing 4 hours of SOT.

    - On day 2, I decide to attack another suggestion of yours: that my phone is defectuous and that I should exchange it. To be honest, I did not believe in it even before starting because this is an issue that I have been having since my S7 edge. So I took my wives S8, installed all my settings on it, and I got a disappointing 4 hours of SOT. Defectuous phone theory discarded. This also means that we can disregard the Factory Reset theory.

    - On day 3 (today) I tried to see if most of you were right. Many of you tell me that all my problems are due to my carrier signal, coupled with the fact that I am roaming. I actually believed it could be true, and I wanted to get a local sim card from a different carrier to test it out. But I ended up doing even better!!!! This morning when I arrived at the office, I unplugged my phone 100% charged and immediately set it on airplane mode with Wifi on. No phone radio at all! And I used the phone just as I would any normal day. Well guess what ??!!! A disappointing 4 hours of SOT.

    I only have a few ideas left to test, and here is what I plan to do in the next few days.

    - On day 4, I will toggle off the Sync on my phone. The reason why I am doing this is to find out if some kind of sync is draining my battery in the background. Maybe the google backups, my email client, the fact that I have my phone synched with my iCloud email contacts and calendars... Let's see if this makes a difference. \

    - If it does not, on day 5, I will reconsider the whole way I use my phone. To that effect, I will delete the app that I use the most: Instagram. I will do a normal day except I will not browse instagram from my phone to see if the routines I have are the problem and my battery drain is relative to the way I use my phone on an everyday basis.

    - If this does not help, on day 6, 7, 8 and 9, I will be willing to try anything that any of you here might suggest between now an then. I would particularly like to hear from Erasat, who has helped me a lot in the past two years trying to solve my issues with bad SOT, but I'd be glad to hear from anyone else too.

    If nothing of this ends up working and I never identify my problem, three things will happen then:

    - I will cry myself to sleep until I heal and start feeling better (might need to see a shrink to treat my battery anxiety for that)
    - In order to feel better, I will convince myself that all of you were in need of money to finish the month, and that you accepted a bribe from samsung to post crazy SOT on forums all over the world wide web (Im only half joking here)
    - I will buy a car charger and live with this burden for the rest of my days.

    Any help will be much appreciated.

    Cheers,
    Steven
    Alright another day, another test.
    Today I toggled off the Sync to see if there was something stealthily draining my bad.
    Result: I managed to get 4h30 of sot instead of 4 hours. Still crappy right ? I bet those of you with the 8 hour sot would have given you an extra 4 hours if you had done the same.

    So the struggle continues.
    Tomorrow is the greenify test. Let's see the impact.
    Everyday I'm closer and closer to believe that you all work for Samsung here.

    What are you talking about? The iPhone 7 has a 4 core processor. Its performance in multicore benchmarks is only slightly behind the S8 while the single core benchmarks completely destroy the S8. Let me also tell you that I've used Android phones for several years from the very start of Android. I've flashed custom roms and kernels almost every day, rooted and customized to excess. Then I switched to the iPhone 6 and didn't look back. Everything just works out of the box without the hassle of customization. I could finally relax and concentrate on using apps. And I didn't have to worry every day, if it was going to be a good or bad battery day (like bad hair day). Because other than the iPhone I always found battery life on Android inconsistent as there are very often apps draining power in the background. But I respect the progress Android has made over the years.

    My bad for the dual core part (i don't watch stuff about iphones didn't know) though I've tried iphones 3 times(4s,5,6 plus) i always miss to be able to have more on my home screen + i like to put things wherever i want options and android always worked for me no matter how many years i've had the phone and my battery always was standard duration i'd say (4-5 ost) my usage vary so does charge. Overall, never was disappointed with android and without options i get too bored of the UI.

    Yeah I'm still good too. I'm getting 7.45-8 hours on 4glte with all settings maxed out besides location on. I never leave that on. And 10 hours OST on WiFi. That's fine by me. I had one bad day where my signal must have been screwy.

    Nah just one bad day. 7. 45 - 8 hours OST on strictly 4glte. 10 hours OST on WiFi, average over an hour OST per 10 percent actually on WIFI as you can see below



    If I mix it up and use WiFi and 4glte I get anywhere from 8.5-9.5 hours OST.

    Agreed 100%. An iPhone is nothing to brag about. I've been hearing this optimization crap for years now. That blanket statement doesn't apply anymore.

    Buddy if you're still getting only 4.3 hours of on screen time you need to return the phone. That's not normal. It's impossible unless you are getting 1-2 bars, with maybe a 3 thrown in here and there, max ALL DAY LONG and have no WiFi running on top of it. With say maybe max brightness all the way up at all times. No auto. And location on.

    If this phones battery had 4 hours OST, as in the actual battery life that everyone was getting including myself, I'd return it immediately and get another brand. Samsung would probably be in serious **** too. They'd never release a the s8 or + with that battery life. It would be a disaster. Especially after the note fiasco. They'd say one blows up, and the that doesn't can't hold a charge. Their most powerful phone ever has only 4 hours OST. Can't imagine that. It's crazy and would be the downfall of samsung.

    Got my regular S8 and have been using it for the last 4 days. Location turned on (battery saving), sync on (multiple email accounts), brightness set around 40%, AOD on, wifi on roughly 30% of the time and rest with LTE. Been getting 8.5hrs of usage with 3.5 to 4 hr SOT and 1-1.5hr phone calls. Coming from an iPhone 7 which consistently gave me 6.5-7hr usage. Only thing am dreading with my S8 is the battery performance on roaming when I travel.
    Surprised by the overnight AOD stand by endurance of the S8. Seem to be losing just about 4-5% over 8hours. Well done Samsung!
    This will turn out to be a happy purchase if these figures remain consistent over time (something my iPhone 7 did over the last 6 months)!
    Looking at some of S8+ owners post, I feel S8 is short of 2-2.5hours of usage. Not bad for a phone that has a much smaller footprint and easy to operate with one hand.

    This is such an ignorant comment it's laughable. Maybe you should go buy an iPhone and really compare it. Bash on Apple all you want and praise Android or Samsung or whatever, but an iPhone is always going to be an optimized device, and an Android will never be one, not unless it's a Google Pixel device. That is the only Android device that actually compares to the iPhone when it comes to optimizing the software for the hardware. Seeing as I have no loyalty to any brand I am at least more objective about the pros and cons of each platform. Next you'll tell me how Android apps have comparable quality and performance to those on iOS.

    Anyway, back on topic, battery life and all that. I'm up to about 6h-6.5h SOT now on regular basis with my S8+, so I'm getting to be in line with my S7 Edge. No improvement but at least it seems to have settled into about the same battery life as what I had before. Only thing I keep disabled is AOD as it needlessly drains my battery during idle time. I also had this generally disabled on my S7 Edge. I bet if I was not using Snapdragon chip I'd be able to squeeze out another 30-60 minutes.

    Pretty happy with my S8. Been getting 3.5-4hrs on SOT with location on, LTE on, sync on and 1 to 2 hours of voice calls. Been clocking 8hrs of usage thru a 15hr day. Am getting impressive AOD stand by endurance overnight with just 4-5% drain over 8 hrs. Galaxy S8 / S8 + Battery Life Thread-screenshot_20170506-104120.jpg
