Screen on time - Xiaomi Mi 8 Real Life Review

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Xiaomi Mi 8 before depleting the battery.
Then, drop a comment if you have anything to add!

Can any of the device owners share their experience so far with it?

I'm on xiaomi.eu MIUI 10 open beta so battery life can be better when it's stable. Buts it's pretty decent right now I'm happy with it.
15 percent per hour if display is on. If display off than 0.5 percent.
On my usage I get two days.

Battery life is a good surprise, I'm using xiaomi eu

My MI 8 can reach upto 7h30 on-screen time, how about you #5 and #n?

The battery is what I was looking for in a smartphone. Constantly using it (web browsing, facebooking, gaming, youtubing, etc.) for a day, it could last around 8hrs or more, playing games heavily it could drop to 6hrs. I have been using the phone for around 2hrs per day, and it could last up to 3 days. Ah, I have Always-On enabled. My rom is still China, waiting for bypass time to unlock it.

How do you get that SOT? I'm on xiaomi.eu 8.8.30 and max I get is 5 hours

So you are on miui 10 beta, i am still on miui 9.6.7, i hope it is not the issue. I put most of my apps to "not running in background", some are set with no restriction. But the system still kills all apps once in a while, i am new to xiaomi phone so I still dont know if this can be disabled or not. I have not installed all of my daily drive apps because I want to unlock the bootloader and flash global rom first, i also hope this is not the issue
My normal standby drain is about 12hrs for 10%. Oh, I do go battery settings to solve any detected issues when I am on break. I also hide the notch.

Battery life is solid, running china dev and i get 2 days with total ot 5+ hours SOT. For a non stop use indoor i can go 8+ hours

xiaomi.eu ROM (up to 8.8.30) drains battery fast, 15-20% per hour with screen on, = maximum of 4.5-5h SOT. With global stable or global beta ROM getting around 8-8.5h SOT, 10-15% during usage.

Yesterday i bought the phone, fully charged and at 25% i got 7h+ screen on time.. which is completely amazing!! Global stable 9.6 here..

You can easily get over 7 hours of SOT, and more than 30 hours on one charge.

Hi people I wanna alert everybody: DO NOT UPGRADE TO MIUI 10. It drains so much battery than miui 9.6 stable. I've wiped full data, it drains less than before ,but more than 9.6. global stable. I post screeshots

LTE - 4-6h depends on usage

I've got easy 8 hours on WiFi (YouTube, Facebook and so on)

What 's about your SOT?

Please share your screen on time in single charge .
Thank you guys.
I hit nearly 10 hours yesterday. Todays charge I'm on 7h 48m with 18% left
All on miui.eu build.
6 to 7 hours, miui 10.2.8
10h-12h medium usage. no gaming but stream a lot. 2 weeks old device.
7 and half hours max with gaming included
I'll tell you ASAP 'cause I've bought it today
Its 6-7 hours. LTE range is not good in my area so its around 6 and half on 4G. When on 2G or 3G and WiFi , SOT goes beyond 7 and half. My usage is browsing only, no gaming.
5h to 6 with miui 10.3.6
what's wrong with me, i can't go over 4h on sot ?? miui 10.3.6

Debloat MiUi. USE LTE ONLY ON ONE SIM. Select 2G on other.
you know what, i install miui global eea v10.3.2.0 and update to v10.3.2.0 and look the result is too good!!
Mine
I was initially getting ridiculously good SoT, easily above 10h while GPS, Bluetooth, Sync etc. all open.
Since last week, Play Services started to eat battery a lot. Still well above 7-8h SoT, and it's more than enough, but it's weird :/

Ah yes. Is it responsible for this?
Also to be fair, yesterday I still got 9 hour SoT, but I think originally it was longer.
I don't get what i'm doing wrong, i basically installed resurrection rom with elvira kernel and i barely get 4 hours of sot trough a workday
am i doing something wrong

I've red somewhere that it could be responsible of some battery drain.. Go in battery settings and turn off any background process for the gcam.
Syberia is absolutely amazing rom!
First cycle of charge... See screenshots ... All out of the box... Kernel stock and anyone configuration to save battery...
I'm absolutely freaked and happy!
on MIUI 5 days bought
12hs screen
Finally I got this phone.
And I'm happy with that.
Usage 4 days.

I have been very happy with battery life so far.
Screen is on 90hz qhd+
90% on wifi
Sot of 7 hours and 5 minutes.
Been of the charger for 15 hours.
Still 16% battery left.
First day of moderate usage with qhd and 90 hz
90 hz fhd betwen 7-8 hours screen on time normal use social media youtube and some light games (except pubg that game is a battery killer ) with quad hd didn't tested yet !
Fourth day with the op7t pro and I've noticed that the screen on time is even worse than on my 3 years old OnePlus 3...
I'm getting 3 to 4 hours of screen on time in normal usage. Google, social media and Netflix/YouTube.
If I start playing games the sot drops below 3 hours
I'll send it back and buy another smartphone. It's not acceptable to have 3 hours of sot for a brand new flagship
have you tried a hard reset in your phone , dark mode , and battery saver as well because 7t pro can do better than that

I have a 6-8 SOT usually (90hz and automatic resolution). Give it some days to stabilize. Battery on first days was bad. Now it's amazing
I average too around 7 hours of sot. Pretty good I would say.
I'm really thinking about giving it a try but SOT is very important to me and no phone has come close to my mate 20 pro this year and I returned every one I tested. But never tried a oneplus so... Wireless charging is really something i would miss for sure so I'm still hesitating. And the mixed results given here don't confort me into buying it...
Display -FHD 90 HZ Brightnes 50% dark mode on
only wifi no sim cards on it used for netflix , youtube facebook , browser and camera

Well... Now it's even worse. I'm getting like 3 hours (of even less) of screen on time.
Automatic resolution, 90Hz, only wifi, 1/3 of brightness, black/dark mode everywhere, only social media and video (yt and Netflix).
I'll send it back. It's unacceptable for a flagship to get under 3 hours of sot. I have to plug in my OnePlus 7t pro 2-3 times a day
Amazing SOT
Fantastic battery life! 90hz+QHD with latest Ex Kernel.

The only kernel that officially supports the T series is Ex Kernel. However, I'm using Kirisakura Kernel atm without any issues on my 7T Pro.
Poor sot
I get around 5 to 5 and half hours max.
Disappointed as my friend gets 8 to 8 and half hours screen on time. What should I do?

Many threads mention WhatsApp as the culprit. The latest beta should fix the drain.
Whatsapp Beta APKMirror

Will post screenshots when its drained
Amazing
55% left.... No charge beetween. Most of the time wifi. Low brightness ~30-50%. Everything blacked (substratum) also Samsung browser dark mode...

I got the Xiaomi Redmi K30 (4G - 6GB+128GB) directly from China through a friend. My very first Xiaomi and boy what an amazing battery this phone has! Coming from Samsung I've been literally blown away. I thought such battery life was always limited to XDA threads and hence this was truly a dream come true lol. And for $250, this has been the cheapest phone I've ever bought. So much value this has to offer.
This is my first charge cycle of the phone.
I am yet to fully move all my apps to the Redmi K30 yet. Only Gmail, other Google apps including Chrome were mainly used with some very light gaming (I'm no gamer). And I uninstalled many of the apps that came with the phone.
Its running MIUI 11.0.3 on Chinese stock ROM. 4G LTE on all day (not connected to WiFi at all). Screen refresh rate set at 120Hz.
Usage was mainly fiddling around with the phone setting it up and installing Google apps, 2 hours of voice calls, 30 mins of videos on YouTube, 15 mins of games. I am yet to drain my battery fully. So halfway through at 50% mark, I have used the phone for over 24 hrs with 4+ SOT.
Stand by drain has been amazing as I've already slept through two nights where battery drained only 1% (!!!) over 6-7 hrs. For me, this battery life is purely insane!
I will post again once I manage to deplete the battery fully.
-- EDIT -- FULL UPDATE
The battery was finally about to die after 2 days! (48 hrs!!!) With 7 hrs of SOT ?
In addition to the above, I further used the camera to take a few pictures, Maps/GPS and more fiddling around.
4G LTE (mobile data not WiFi) was on and connected throughout using a single SIM. Battery Saver mode was not activated as I wanted to see how far it could stretch. Screen refresh rate set at 120Hz.
Drains fast when 120hz but with 60hz amazing battery life, i must say. Even got 9 hours SOT in 60hz with small games and YouTube on speakers.
11 (ELEVEN) hrs of SOT!!!
3rd Charge Cycle -
Screen refresh rate set at 60Hz
4G LTE on all day (not connected to WiFi at all)
2 hrs of YouTube video/music playback
1 hr of voice calls
Connected to Bluetooth earbuds for media
Lot of messaging on WhatsApp
Random browsing
Installing apps
Battery Saver mode was NOT activated
Face Unlock with Raise to Wake enabled
Verdict on SOT range - 7 hrs (120Hz) to 11 hrs (60Hz)
Redmi K30 (stock CN ROM with MIUI 11.0.3)

How to check SOT btw
Sent from my POCO X2 using Tapatalk
OK got it, It's about 7 and half hours.. Not bad I guess.. Use 120 hz.. Though use battery saver and location off.. Data is on most of the time
Sent from my POCO X2 using Tapatalk
10-11 hrs on avg(120hz) or even more
0% battery drain
I dont play any games just normal apps like social apps,spotify,reddit,chrome,etc
I am using pixel experience plus rom(with location and auto sync off)
Coming from Galaxy Note 8, the battery life is really impressive. Im on china rom with google play install. 60hz and on wifi all the time. No games. Just watch some videos and surfing the web. And social media such as whatsapp, instagram and telegram is also used. Planning to switch to xiaomu.eu rom after my bootloader has been unlock which I need to wait for 168 hours.
Edit: since I could not upload the image I will just say it. 23 since last charge with over 7 hours sot with 50% battery left.

in my Poco X2, before i got maximum 4 hours SOT with 120hz, then i uninstalled mi pay, security, credit, music, video, browser, mi drop, mi mover, getapps and signed out from miui...cant believe ...my bluetooth, net, hotspot is always on for my office work...but after that i got 11 hours SOT....i recharged my phone now 2 days back...now i know mi bloatware is the main culprit for battery draining and security

6 month old phone, I'm getting only 4hrs SOT on 120hz and 5hrs on 60hz. I don't game, no heavy use, I've almost tried all custom roms and supee debloating my mi rom, still no profit. Idk how to get better battery life at this point, I used to get 12hrs sot in my op5t
120hz
WiFi(when i was home)
LTE(outside)
Miui 12.0.2.0
30%-50% brightness

I had a Oneplus 3 since october 2016 and I did not realised how bad the battery was. During the last 2 years I had 2h30 of sot MAX, mosty 2h.
With the Oneplus Nord, after the first charge I got 4h30 of sot (36 hours of usage) and still 21% battery left.
I don't game, mostly web browsing.

This has me a bit worried. I have had a Huawei mate 20 and a Xiaomi mij 9t pro that got me 6 to 7 hours easily... And those had 4000 mAh.
This proves everything is relative. It is more than enough for me.
Don't forget It was only the first cycle so I cannot conclude anything yet.
Not to bad after 4 day's actually. 5.5 hours SOT and 33% left. Most of the time spend on WiFi though.
9h
Just web browsing. Little youtube , 30 minutes or so. Wifi. Brightness auto.
Update
Well , there it is.
Battery is great. Period.
Battery is great. Usually I get 7-8 of sot. Also the charging is ridiculously fast for me as I switched from a 4 year old phone with just a 5 watt charger.
Also getting 7-8 hours screen time. impressed

Nice how are your settings and how much standby time ?
Check on lte or 5g only and show the graphs .
Battery drainage is not just a nord domain.
Very satisfied
I only charged twice so far, but both times I barely got over 6 hours SOT. Using 60hz, on WiFi, mostly just browsing web, no gaming.
Do you think battery will get better with time?

Your screen shot shows battery life that is massively better than any other reports I have ever seen. Literally close to double anyone else. It makes me a little skeptical.

Well maybe it is so high because I did not used the phone that much then and it was new , not so many apps instaled .
Now a get max 8 hours .
So , it just hapend I guess.
One HIT wonder like. ?
I am barely getting 4-5 hours of SoT. Is there something that I need to do to boost up my battery life?
When I first got the phone battery life was just ok 4 hrs sot. After 5 days its improved by quite a bit including the latest September update.
Am on 90hz all the time. Blocked all Facebook. So far its ok. Would have been great if it had a slightly bigger battery.
I will get an 6 or 7 hrs screen on time on 90hz,
In this picture iam using continues hotspot thats why its low

Miui EU 12.0.3.0 - SOT

Hi,
I have a Mi 9T with the official EU rom 12.0.3.0.
I am not a hard user, only using emails, whatsapp, internet ... (no games or movies) but I only have 5-6 hours SOT.
I have as well restricted many apps in the background.
The battery is not draining when I am not using my phone, or a very little drain 2% but as soon as i use my phone, the battery goes down very quick.
Main consumer is Android system with 30%.
I did a factory reset on the 12.0.2.0 version, still bad SOT and last week I had the 12.0.3.0 update, SOT unchanged (5-6 hours).
I have seen many subjects on the forum but i feel like not everybody found a solution for having a nice SOT (8-10 hours). I usually keep my phone 2 days without charging it, with same apps. But today i mostly need to charge it everyday.
Are you guys in the same boat?
If not what is your SOT, and what ROM or setting do you use?
I would prefer to stay on a official ROM if possible.
I becoming desperate with this poor SOT, thinking to go back on miu10... which is a shame because i bought this phone to enjoy last os.
Cheers,
You can try the global version,( 12.0.5) or a custom rom like xiaomi.eu that uses a debloat version of chinese rom, stable and weekly.

SOT means Screen On Time, you can see it in "Battery & performance -> Battery usage stats.
Right now, my SOT is 2h40min and I have 46% battery left. So I would probably get around 5hours SOT once my battery is gone.
I think it is very little but I would like to know if people have similar SOT to mine?
First of all screw miui ,if y are a practical orientated person who only cares about

Please flash a rom which is caf based ASOP doesn't make sense to Snapdragon driven phone
*I myself use pa quartz 4 edition ( sadly no quartz 5 )
*I got upto 14 hours of sot once that was just with browsing @25-30% brightness with mobile data on
*I've restricted all unwanted **** including google assistant , I'm running gappa pico edition , I use Google Chrome for satisfying my needs of Gmaps , Gmail etc. ( Ofcourse I've disabled "Google" app too, along with vibration and all kinds of hepatic feedback including touch sounds on dialer )
And I get An average of 10 hours SOT watch the screen shot.
I'm talking every 10%=1hour or 1hour+.
TRADEOFF : FOD - in this rom fod never works fine and is broken. if you need fod or if you prefer it over the double tap to wake + pattern mode which I myself use now you should rather get yourself PIXEL EXPERIENCE or lineage os 17.1 . (FOD WORKS Steamlessy on PE rom , 2ndly on lineage os but battery life never gets better than this it's always under 10 hours but all these 3 are way ahead of all miui roms which no MI bloatware and fake optimization only part about miui is that FOD and our device has a lot of hidden bugs which you don't find in our day to day usage which I got exposed to myself after messing up my persist image a while back ).
The last versioni of miui 12 and 11 have bad sot. On 12.0.2 i had also a battery drain with screen of now on the 12.0.3 in 7 hours i have 3% of battery discarghe with screen off but with screen on the drain Is vert higt 20% of hour.

Thank you, we have the same problem.
So what have you done? Are you using another ROM now?
I'm on MIUI Global 12.0.3.0 and I constantly get max of 4.5 hours SOT.
1 hour calls
3 hours social media and messaging
Brightness around 90% fixed
mixed LTE & WIFI usage

Hi, yes I see yours is even worse than mine.
Have you tried a factory reset with the new 12.0.3.0?
I guess you should try to use automatic brightness because 90% is a lot and may consume lots of energy.
The last 2 days, I have tried the saver mode and the battery actually last much longer.
I am around 8.5-9 hours SOT now. I have activated the auto synchronisation to get updates in live.
I will continue on this set up this week, but I am pretty happy with this SOT, it gave me almost 2 days without charging now.
