Galaxy S8 / S8 + Battery Life Thread

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.

Yeah I know this battery test video. But two things: 1. no one knows, how old the tested iPhone 7 was already and 2. no one else on the internet got similar results from testing these devices.

Actually I remember another youtuber who did a battery test and S8+ won, just can`t remember the name.
 
I'm on s8+. I optimised it as much as I could to save battery and I still won't pass 4hrs sot or 12 hours off the charger

Unless you're in a bad service area
There's something wrong with your device, you should try and replace it

My s8 + gives me 5 hours screen on time before the battery reaches 50%
And that's with WiFi on Bluetooth on
Streaming music for 2 hours, whd+ all the time... Everything to full capacity

Lol what's the point of FHD if we're getting 7 and 8 hours with Quad hd?

Exactly
I'm on wqhd+ since day one
Battery life is amazing
I go to bed at night with over 50% juice still on my battery on most nights and that's with 5-6 hours screen on time
I'm always on my phone (heavy user here) s8 plus

Is my battery performing properly ?

The screen was on FHD and no Wi-Fi used today. I've been browsing with Chrome, texting, using twitter and facebook. The results from you guys are really amazing even with the wqhd screen that I have to consider mine again.

I just switched from iPhone and I never notice battery lost overnight before in iPhone and I felt like the battery drains really fast comparing with my old iPhone 6+

Some people don't care about some features on either phone ie: speakers and camera which i dont use often enough to cry about and battery life is always subjective as apple and samsung probably don't have the same power management +,haven't seen alot of people saying the iphone had better battery life but I'd be interested in reading one if you could provide a link.

Here is a link to a review, in which the iPhone 7 Plus comes on top in battery life:

http://www.phonearena.com/reviews/Samsung-Galaxy-S8-Plus-vs-Apple-iPhone-7-Plus_id4334/page/4

My point was not to say that the iPhone 7 Plus has superior hardware or that the mentioned features are necessary for everyone. I just couldn't agree with someone saying the iPhone hardware is cheap and trash.
 
No worries my man :) i'm open minded + curious about battery life stats also ,i've used iphones before and i do agree the hardware was something but imo it dosen't compete with the s8 and the taptic engine to me feels too much like a gimmick (just like edge features on the s8 which i barely use) Overall though apple is more for people who have multiple apple products already,their ecosystem hasen't been touched by anyone yet that i know of,me ? I just prefer android in general.

Btw thx for the link ahah first time i see the iphone coming on top though made me chuckle XD.
 
LMAO at the review... Fan boy much? (that is in reference to the article... not the person that posted it :))
