I owned the galaxy S9 (dual sim - 128gb - exynos) since july, my battery doesn't last a whole day, all I get is 4-4.5 hours of SOT. I installed phone info for samsung from play store and checked the battery status, it says that battery health is 91.37%.
And my phone is warm most of the time, not extremely hot, just a little bit. Is it normal? Or my phone has a problem?

Same as mine, feel warm all the time, even not using it. 3hours+ SOT per full charge. Bought it on end of June 2018. After 100 cycles phone info shows 86.53%.

Don't worry about that, I don't think it can be accurate, mine says 84.97% after 54 cycles, and I'm fairly sure I remember it saying it was only about 90% when it was new, so I'd add 10% onto that %
Will wiping system cache help to decrease heat and improve battery life?
Check for any apps that may be constantly functioning in the background, streaming apps that are not closed, etc. GSam is a good app for monitoring this.
Recently, I am not charging my phone like I was doing before, I mean sometimes I recharge it to 100% when it's at 60% for example, or sometimes I let it drop to 10% or lower. Because of university needs...
But I'm noticing a very bad battery life that it lasts me about 16 hours with 2-3 hours of SOT (I only use whatsapp and open some documents at university).
And my phones gets hot sometimes like I said before.
And sometimes I unplug it and after 2 mins it drops from 100% to 98%. The battery drains too quickly! What's the problem here? (I also notice a higher % for android system usage, like 13% or 16% for example)
PS : I tried wiping cache and I saw some apps running in the background and putted them on "always sleeping apps" except of social media apps. But they still run, I can see this in RAM usage. So don't know what to do.

Thanks bro! But I am asking why I need to do all this stuff to make a flagship phone last me the whole day, my friend's s9 battery lasts the whole day with 6 hours of SOT without disabling apps, or optimizing them. And without putting a dark theme...

So my battery life so far has been hugely inconsistent. The first day it was draining so fast (60% in an hour) that I contemplated turning around and taking it right back to the Verizon store.
I decided to give it a better chance than that and gave it a full conditioning cycle and all seemed well - I got 16 hours with moderate usage including an hour and a half where my screen was constantly on! I was very pleased. Extremely pleased.
So I charge my phone back up to 100% before I go to sleep then take it off the charger once it does. I drift off into dreamland, dead to the world, and five hours later I decided to check my phone for calls, texts and email.
Before I could even pull my notification bar down I saw something horrific - an extremely low battery capacity, nearly red. Checked battery usage and it said it went from 100% to 13% in about 5.5 hours.
Android OS - 64%
Phone Idle - 10%
This is the big indicator. Under Android OS, my phone (not the display) was kept awake for an hour and a half overnight. I'm really not sure what's going on here and what's causing this to happen. I haven't downloaded much - 1 game, Skype, Google Reader, Facebook, Tweetcaster, Evernote and Foursquare - and none of them showed any signs of being the culprit.
As you can tell, this is very worrisome. If I can't get more than 5.5 hours on a full charge what use is this phone to me? Does anyone know what could be going on or has anyone else run into this issue?

Thank you! I will direct my attention over there. Mods please close this thread.
My battery stats have improved greatly by turning off location completely.
Took it off charge at 6am and with heavy usage
YouTube internet calls etc
still have 65% 16.5 hrs later.:good:
Just starting to play with battery use on my new G5. 100% charged 10 hours ago just before bed.
On a day to day basis i am a pretty light user. Calls and texts mainly.
Left phone unpluggged so it slept and 7 1/2 hours layer its at 93%.
20 mins music and email checking 19 hours in its at 88%.
Have Greenified much in the way of apps which i think improved things. Compared to the Sony i had the G5 seems to have ok battery life.
Its certainly in the useful, full day and better range.

Is yours rooted? I tend to get 5+ hours screen on time sometimes 7 which is amazing for a phone this cheap.
Same here, I have about 4-5 hours of screen on time with greenify, non-rooted. I'm a regular user, messenger, emailing, browsing, spotify etc. I'm also using Adguard which has its impact on the battery but a small price compared to having ads all over the place

Nope, no root as yet. And actually i may not depending on what ROMS become available in the future. Pretty happy with the way this is setting up and Android 7.0 stock. I think i may well leave it unrooted until after Android O hits and see where i go from there.
i'm rooted and the battery is very good, i got 7,5 hours SOT, usually i have 5-6 H of calls and 3H of SOT, 2 sims active, wifi and 4g always on, and the battery is 20-25% when i put on charging from evening to the morning. Very happy with this battery

Very good battery for price of the handset
I don´t know it´s a isolated case, but since i bought the phone, the battery is pretty bad, yesterday i tried to charge with another power adapter and my battery it´s lasting longer, anyone have this same problem?
Sometimes this happens to me.
When i keep my phone overnight(Battery Saver ON) even wid a charge of 60-70%, next day mrng, the battery is completely drained and phone is OFF. This doesnt happen daily, happens only sometimes. Any guesses why dis happens?
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Samsung Galaxy S8+'s battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

Hello. I've recieved my mobile phone about week ago and there is one problem that annoys me. While the phone has lcd turned off, it drains a lot of energy. For example, yesterday I slept 7h and the battery decreased from 80 to 50%! I've tried almost everything, offline mode, aod off, battery saver mode etc. Any solutions?
Not that much
I think it's a lot ! I've seen many baterry usage screenshots and I was impressed. But mine is some kind of joke. I can't even use my mobile phone often at work because it's dead from 8 to 16, with all options turned off - aod, sync, gps etc. Also with baterry saving mode. Please guys, there must be a way to fix that.

Maybe try and disable bloatware using BK package disabler. It helped for me after disabling a few things
Unfortunately it did not work. I've tried everyrhing..
with only wifi and sync on, battery drains 3% from 11PM to 6AM
4G on
Wi-Fi on
Sync on
Over night From 12 to 8am is 2-3%
Not more.
there's a hundred settings for better battery life, putting apps to sleep, app background data, app data while data saving, notifications, permissions, etc etc etc....
Change network mode to 2G only. You will see standby consumption go from 1-1.5% per hr to .3-.5% per hour guaranteed. Obviously more drain if using always on display and/or other heavy features. Works perfect for me as my s8 is my secondary phone and don't need 4g.
ps. sot currently was like 6 mintues so didnt post screenshot of that, although im able to get around 5-7hrs sot with about 24hrs total use time. Also rom is renovate ice note 8 port ver .1 all stock settings otherwise. Also i got pretty much the same battery runtimes with stock or custom roms. Same usage with lte/3g/2g setting enabled got me nearly 5/6 hrs sot with around 16hrs total usage but really standby was affected by this setting change.

how much would it be with AOD on ?
Snapdragon S8+ rooted.
Not touching the phone, I lose about 10% per hour. A thirty minute drive to work, with Pandora the only app in use, it runs through somewhere between 15-20%. I've tried everything, including telling its mother and using the kitchen sink, but nothing helps. One day we weren't busy at work, and I forgot my charger at home. By 11am I was at 9% (that's after leaving the house at 7:30am) and had to make a run to Walmart for a charger. On a normal day, I have to charge it 2-3 times. On an extreme use day, I have a constant tether.
Not that much
I lose 3% or so over 8 hours of sleep. Make sure you go through your battery management and options to end draining apps when left in the background.
Stock US unlocked S8+
I'm going to leave my S8+ (unlocked) history so that others can relate and solve as i did:
Bought mine with a German ROM (DBT), and as soon i as connected it to Wi-Fi it got updated to QH3 (latest).
Notice immediately a "Android System" drain that would take over almost 50% of phone sleep time. After some days decided to a "Reset / Factory default" but same story, drain ...
Solution ? Flash different region software (PHN - Netherlands - G955FXXU1AQI7 )
Now it sleeps like a baby and "Android System" remains very low.
Imm experiencing huge battery drainage since the new firmware update......no clue why
Oh and my phone is warm in idle and becomes quite hot when doing low intensity tasks such as loading this site
It's too bad

If this true, I may give up to purchase one. I don't like to bring a power sink. And there is not always have a store that I can charge my device.

That's been my, my son's, and several other people's (in the root threads) experience. There are a whole slew of people that have great battery life with root, but mine is abhorrent. I actually went back to stock, and have been astounded how much longer the battery lasts compared to having it rooted.

Program Tasker to switch off all internet access, auto sync and wifi and Bluetooth. Once switched on, the phone will regain all functions. In a 12 hour shift, with occasional use, I lose about 20% of battery power.
I like Galaxy S8
This is best phone I every wanted. Galaxy S8 is best device in its own. No one can beat it.
I've a brand new Xiaomi Mi 10T Lite, but since a few days I notice that it seems that the battery is draining fast.
So I've done a test: I've charged my phone to 100% and used it until it turned off due to too low battery and it lasted 23 hours and 3 minutes.
But I doubt if this is normal and I'm kinda worried about it.
I've bluetooth off, and wifi is always on except when I go outside and then I use mobile data.
I use my phone for surfing, using social media, chatting, gaming, making nice pics and more.
So is the battery life normal or is this a serious problem?
is 23hr bad ? I feel like my one is always above 80% as it charges that fast I don't seem to notice the battery being low

I dunno
I haven't mentioned the standby time and the active time in the topic, and I cannot find that data anymore so that means I have to do the test again
I would advise to install AccuBattery app, fully charge the phone and look at screen off and screen on power consumption at the end of the day.
These numbers are "normal":
Screen off - no activity (over night or phone just laying down for a few hours): 0.2-0.3%/h
Screen off - the usual daily activity (moving around with the phone in the pocket, Whatsapp for web active, Google location tracking active etc.): up to 1.3%/h
Screen on - about 7-9%/h
I'll do another test on Friday as I said.
I'll charge the phone to 100% and use it until the phone turns itself off due to low battery and look at the active time then.
I'll post the results here if the test is done.
What were the results?

My phone is pretty new and I am using it more frequently these days. This leads to similar battery times like you describe them.
I did not do the exact same discharging like you did, but imo battery drains mainly during screen-on time. Over night it is quite stable and only slowly discharging.
Maybe power consumption is dominated by the LED screen? This might be the reason why Xiaomi has such an aggressive screen dimming implemented...
I think what _mysiak_ is describing above, is pretty accurate and explains what you are observing.

Unless your trying to calibrate the battery that's really stressful to the battery to use it like that.

Im planning to buy OnePlus 9 pro phone, everything in this phone is perfect for my needs except the battery life. almost all the reviews on the internet suggest that the battery life of the phone is average, and some site say it's worse than that of the oneplus 8 pro, even though both phones have roughly the same battery capacity with the oneplus 9 pro having more efficient display and processor. so do you think it will be improved soon with a software update? and for those how bought the oneplus 8 pro at lunch last year, did you experience the same issue?
It charges to 100% in under 30min...
So seriously, what is it that you do all day where you need to have your screen on for 6-7h, hard usage, without any acces to a power plug to charge it?
Are you a ranger in a Safari Park that tracks Rhino's?
Battery life isn't great, but I top it off for about 10-15 minutes late afternoon (half a charge or so) and I'm good to go. I'll keep my old 30W charger (from my 7 Pro) in my car just in case I'm ever caught with a low battery, but it doesn't seem to be an issue. I certainly welcome any improvements, though.
Usually, ota updates have battery performance improvements...
In the summer i will be moving back home where frequent blackouts are a common thing specially during the hot days, that is why im worried about battery life. and i dont like carrying power banks.
Anyway thanks guys for the replys, and hope future updates would include battery improvements.

I've upgraded from a Samsung Galaxy Note 9. I'm really surprised how quickly my phone has died the past few days at work. Only gets me through about 8hr of listening to podcasts, screen off before I hit 20%. I hope that something improves because I was hoping with this phone I'd be able to get through more of my day without charging.
It's astonishing to me that all the improvements to hardware and particularly power efficiency over the years have resulted in... the same SOT and battery life in general as my four old phone. Progress

They'd rather have the phone charge from 0 to 100% in about 30 minutes so that's their *solution* to the "problem".
Idle or standby battery drain is too much.. Anyone facing that? How to reduce it. My phone was charged 90% in the night. After 9 hrs standby, battery went to 67%. Thats too much battery drain

Mine drains about 5-6 % in 9 h standby. Always-on disabled. Try disabling "listen to hey google all the time", that might be the culprit.
As someone else stated earlier, my battery was horrible when I first got it for a couple of days, then without doing anything, it just got better, like a normal phone. No complaints now. That was my only gripe.
Btw a new update that ends .3.3 seems to be rolling out in India and should further improve battery life. it's great to see they're doing something, hope battery life will get even better.

Yeah I now have my phone for 2 days, it's a garbage battery!
It drains like close to 20% per hour of 'light usage', with low brightness only FHD......
Also it drains the battery even when it's supposed to be Idle (no AOD)!
