Okay... What is up With my Battery Life? - Samsung Galaxy S8 Questions and Answers

Currently running stock 8.0 most recent firmware. Most I can possibly squeeze out is 2.5 hours of SOT with AOD enabled and about 50% screen brightness.
One other issue unrelated is that I simply can not get OEM unlocking to show up in dev options. I have updated manually with the update.zip to the newest firmware and waited multiple weeks and it still hasn't shown up. Not sure if this has anything to do with my horrible battery life. You may say that it seems normal but my battery is supposedly at 89% life and is only lasting until around 5pm, which I'm sure is not the case for most of you.
Relevant screenshots attached. Any help is appreciated!

The latest update seems to have caused this. Mine was affected too, but found a hard reset and careful managing of apps has helped. But still not as good as battery life on Nougat. Hoping the October patch will fix this....whenever that gets released.

I don't know why this is happening to some, but here i can't complain about anything... I am using it like before with all the apps that i have. I even didn't turn off the apps monitor etc.

i dont even use my phone like i used to, and its battery is crappy now ): guess i need to factory reset it so it can be lit as before

Really bad battery life? Help

So I've been experiencing some very bad battery life ever since i got this phone. I get between 5-7 hours of battery life with an average of 3 hours of on screen time. I do use a lot of Spotify, Bluetooth and Instagram. Instagram makes my phone feel hot quickly. Like its using a lot of CPU. I've also noticed i got a few wakelocks. Any help? Anyone got any tips? I don't feel like deleting Instagram neither lol

I also have Instagram Greenified. If i didn't manually close Instagram before shutting the screen off, it would keep running in the background and keep my phone hot.
This might sound stupid, but it worked for me before, but have you tried just restarting the phone? One time I was getting terrible battery life over several battery cycles and doesn't know how to get rid of the wakelock so I restarted my phone and next cycles were a lot better. It might just be a "band-aid" for the real problem, but it might help some.

Radio shows as off+battery frain

So I have been having battery issues on my Note 3 for a while now. Android system has been a large offender of using my battery, but I've also noticed that there are gaps in my mobile network signal. From this post: http://forum.xda-developers.com/showpost.php?p=26891039&postcount=14 I'm gathering that my radio is off? This happens when screen is on, but mostly when it's off. During these times I can get texts, and everything works fine. Just my battery starts to drain faster. The area under my camera also gets rather hot. This is my 2nd Note 3 with this issue, the first one was RMAed because it would not get messages on time.
Does anyone have any idea what could be causing this?

I believe with your radio off you should drain less battery. Mine does it too, and I have awesome battery life without being rooted. Usually well over 24 hours with heavy use, and 6 hours or more on screen time. I recently did a factory reset so maybe that's what you need for better life?

Awful Battery Life! (<2 Hours SoT)

So I've been getting some pretty abysmal battery life so far. Running out of ideas of what to do!

I've done a full factory reset, which made no difference. And the screenshots above were taken with location services completely disabled! Any suggestions?
There's quite a lot of wakelock time from Android OS and Android System, but would that really be enough to cause this much drain? Then there's the problem of actually finding a way to stop it. It's just annoying as otherwise this is a fantastic phone, and I really want to like it, but this is just putting me off.
I think it might good idea install a Wake-lock detector app to whats happening also check this thread

Thanks, I've been taking a look through that thread but haven't found anything specific just yet.
As for a wakelock detector, I'm not rooted just yet, so there's very minimal information I can actually get annoyingly.

Smartmanager showing different battery results?

I've got my Samsung Galaxy S5 SM-G900F running stock rom rooted with CF-Autoroot and debloated with titanium backup.
Since I first got the phone I started checking the battery stats, and from they beginning they seem off, as you can see in theese images:
So this is the first screen I get when I open up the smartmanager battery app:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The strange thing happen when I click "Battery usage", as you can see, there is a 13 hours difference:
How can I fix this, which one do I rely on, is there another, better app I can replace this one with?
Thank you
Anyone?
Top image is estimated battery time left at current usage
Bottom image is estimated battery left at idle, although this changes drastically if you are heavily using the battery before checking stats
Does not seem right either, left my phone with screen off for twelve hours yesterday, and only about 3% down on the battery, which should make it stay on for far more than 1 day 7 hours?

Abnormal Android OS and Android System Battery consumption?

Hello guys, I've been using a 6P for about 3 weeks now, coming from a Nexus 4 with CM13.
I've been getting somewhat between 3,5h to 4,5h of SoT, but everytime I check the Battery graph, the Android System and Android OS consumption seems pretty high. On my old Nexus 4, these two never got over 6%, and I didn't found many reports of those 2 proccesses taking that much bettery.
I don't really know what it can be, and I feel that I should be getting a better battery life if I didn't have this problem.

That SOT sounds about right for this phone, unfortunately. Especially if you are on stock and don't use a custom kernel with battery easy profile.
There are thousands of report of people complaining that they are in the top list but that doesn't matter, what counts is your overall drain. Which is very dependent on the apps you use, your baseband station, and your usage. 4.5h is a good average for this phone.
