what causing the battery drain issue? - Xiaomi Poco F1 Questions & Answers

Nowadays I only get about to 3.5 hrs of sot and if I use it lightly it dies within 12 hrs, Miui astable 10.3.4

long live the miui 9. battery is getting worse with each update.....sadly

Miui 10 Global Beta 9.5.17, stock kernel

Same here. Used to play 5h of pubg when the phone was new. Never wanted to unlock bootloader but looks like trying another ROM is only option left.

Poor battery life?

Is 3 hours of screen on time on Lollipop good? I keep hearing of people that get 5 or 6 hours of screen on time and No android device I get has ever achieved that. Even my xperia z3 tablet compact can't get over 3 hours of Screen on time. Am I doing something wrong? Like could I be using my device too much?
check apps wich draw most battery and get rid of them , if this won't work then do a factory reset ...
I get between 4 1/2 and 7+ SOT hours.
Depends mostly if I turn Bluetooth on (SmartWatch), GPS use (Google+ position tracking, weather),use a lot of Internet (chrome is a battery sucker, you don't believe it), sync a lot of mails n stuff like that.
Of course it depends on your apps, but 3 hours is really not a lot, may be your battery is not good.
The 3 hours screen on time is with heavy usage but the standby time is amazing.

I get 3-4 hours screen on time too. However, that's with heavy use. Viber, Skype & Talkray for 1-2 hours per day. I get 2-3 days standby with 3-4 hours screen on time based on the above. Also some light web browsing and some WhatsApp...

It very much depends on a rom.
I was able to get around 4-5h sot on lollipop, but it was on Google style rom. On some more customized or stock roms you may get a bit worse battery life.
So to answer your question, 3h is a bit below the average result.
The reason may be an old battery.

Old battery? My Z2 is only 2 months old and was bought brand new. :laugh:
Perhaps rom related. Most ever SOT I got was around 4.5 hours and that was on Lollipop Google style rom...

Best Battery life ROM?

Hello guys,
My question is which ROM seem to be best for you in battery life? Im talking about my R3Pro(ido) device. I've been using xiaomi.eu's stables from beginning which has great 8h SOT, but now experiencing like 3h SOT with LineageOS 14 always updated with Xposed and all day data/WiFi on. Any ideas? Should I change back to MIUI?
Thanks

U can try:RR,SudaMod,Lineage OS 15 Unofficial or PixelExperience 8.1.
The UNTEST-20171122 version of Resurrection Remix N has the best battery life for both screen on and off time, hands down. Was a lifesaver in a recent job where I listened to hours of podcasts per day to keep sane. Keep away from Oreo ROMs for the time being, theyre still largely broken apart from PixelExperience (which instead has the fun problem of ridiculously fast battery drain.)

I've installed this version you're talking about on my friend's phone and he cannot go over 3 hours of SOT, he must charge the phone before going to bed.. did you install some kernel too or anything else?

No. The only things I flash on my device are the ROM, GApps and Magisk. The battery usage when the screen is off is the prizewinner here. It rarely goes down more than 2% after being left for more than 2 hours, which is ideal for me. Still though, I'm pretty sure I get more than 3 hours of screen on time. Learn to use some basic battery saving methods; turn the brightness to 50% or lower, turn off wifi or data when you're not using it...or better yet, learn to restrain your usage of it when out and about
When I go out, the phone is generally being used consistently all day via me using Bluetooth headphones along with some occasional use of 4G data. It usually never gets past the 40% mark by time I'm back home and I'm usually out for more than 5-6 hours per day. Honestly I'm not personally sure what the issue with having to charge it daily is...I've never had a phone which didn't require such a task, with the exception of things like the original Nokia 3310.

I did the same on my friend's phone: Rom, gapps mini and Magisk. I can't tell you about his usage of the phone, but I've seen battery stats and it just can barely reach 3 hours of SOT, the usage is mostly of socials and music.. This rom here and latest LOS builds are just very battery draining, I don't know what to do with that phone! Anyway, thank you for the reply and the tips, I'll let him know!
What about MIUI? Maybe the EU version? Somedoby that tried that out can tell which will be the pros and the cons? Is it still on Lollipop?

Ahh, social media apps can very easily drain the battery from what I remember. The Facebook app is especially bad for it if I recall correctly. Perhaps grab a Wakelock detector app, see if anything is keeping the phone awake and then use Greenify to stop the apps from doing that.
With regards to MIUI, I seem to recall stock MIUI (from the official Xiaomi site) definitely having the best battery life out of every other rom I've used, with MIUI.eu not being as good but better than other custom roms. In terms of pros and cons, there isn't much. It works a little differently to regular Android so there's some bothering aspects to it (such as the Files/Documents app being disabled by default for some unexplained reason, meaning you have to re-enable it after every reboot.) And yes, It's still on Lollipop sadly, meaning apps like password managers etc can't use the fingerprint scanner.
Honestly I'd say wipe everything on the phone, clean flash RR-UNTEST and then slowly re-add all the apps and see if one in particular causes heavy battery drain.

Idle Battery Drain workaround on recent 9.5 Global Stable ROM

Hi all.
Just sharing a tip found randomly on Xiaomi forums, and did not see it here, so i though i'd share.
It has been reported that standby times are worse than before on the last two Global Stable ROMs on Redmi 5 Plus ( 9.5.3.0 and 9.5.4.0 ).
Saw it myself, got annoyed, and while browsing, found a post suggesting to disable the fingerprint scanner.
Tried it, and for now, seems to do the trick, the battery graph is as flat as it can be while the phone is sleeping, idle battery drain seems gone (Xiaomi.eu Stable ROM, based on 9.5.4.0).
Cheers !

Battery issue - subpar battery life

Hello everyone!
I bought my Xiaomi Redmi 5 Plus in january this year. Since then I've been more than satisfied with this device. I was using Resurrection Remix v6.1.0 for a couple months when I started to see that my battery was draining faster and faster... Firstly, my phone could charge up to 98%, then it would stop charging... Then there came issues with screen on time... I was barely getting around 5 hours of screen on time. I quickly wiped everything and flashed DotOS which had even worse battery life for me... Now I'm on MIUI 10 Global Beta and things aren't getting better... As you can see by the screenshots in the attachments, my battery is performing terribly. Moreover, 96% seems to be maximum value for my battery since I can't charge it more than that... Can someone give me an insight of what might be going on with my phone?
Unlocking the bootloader and installing custom roms might cause troubles for you and affect the performance.. you should know that.
It seems you are using 4G which drain battery faster than wifi as it appears in your screen.
Check for wakelocks, if [Timerfd] and netlink wakelock exist (with high alarms/wakelocks), then you need to reconnect the battery cable.
i get the same issues on my R5P which i bought back in May. when in install any MIUI rom, it seems that Android System is draining most of the battery.
at first i was getting 5-6 hours SOT. now i struggle to get 3-4 hours with the same usage.
i am currently on crdroid and max battery charge is 98%.
how difficult is it to open the device at reconnect the battery?
i had the same wakelock problem after instaling orange fox recovery and rooted oreo miui 9.
the only solution to wakelocks was to flash with test point method.
it was a very easy process.
for opening the back cover i have used 2 or 3 bits of plastic cutout form water bottle. use scisors for cutting plastic from water bottle.

what rom did you flash first in miflasher? did you flash orange fox afterwards?

A recovery has nothing to do with wakelocks in your ROM.

After some testing several forum users reached the conclusion that test point isn't needed. Disconnecting battery is sufficient.
Test point method implies disconnecting the battery.

flashed 9.8.1.25 beta
I had to do the test method because I have locked my bootloader by mistake and then got a bootloop.
but the wakelock problem has gone
I dont know if orange fox caused the wakelocks but I got those wakelocks like in the first post picture after using orange fox for rooting oreo miui 9.
After that I tried flashing nougat 9.5.4.0 , formating data, doing all the wipes , factory reseting then restoring my backups with twrp but the wakelocks were still present.
only test point method helped me get rid of wakelocks.

use wakelock detector app.
kernel option
i had the same problem before, just discharge your battery to 0% i mean take time until your phone won't boot up and then wait an hour, then charge it for maybe 6 hours (i let mine overnight)
and repeat 3-4 times
if that doesn't work try to calibrate your battery/
good luck!
i just took the back of the phone off, disconnected the battery, reconnected it, booted it up and it charged to 100% in crdroid. testing battery life now.
Thanks for the replies. I'll most probably try the testpoint method and tell you if it worked for me.
Regarding the wake locks, app says that my phone is awake almost 70% of the time even though I used for around 2 hours in a 24 hour period... My phone is going from sleep to awake state every couple of seconds...

Tell us your results after testing
Hey.
IDK if this is going to help but here you go:
Yesterday I flashed via recovery the MIUI 10 Global Stable update for vince, working more flawlessly than Global Betas. I have tested a lot of ROMs for vince and always noticed that MIUI even 9 or 10 has worst battery than PE or any other Android Stock rom (8.1) for vince.
With this MIUI update things changed and I'm having the same statistics (or even better) as Android Stock roms for vince, now I've changed some settings before telling you this.
1- Installed MIUI Hidden Settings.
2- Opened Battery Optimization.
3- Selected all the apps that I could optimize.
Did that this morning (around 8 am) and I'm having this SOT.
Note: Mine is only charing to 98% idk why.
Want best battery life, Miui 10 Stable is shockingly best super smooth and best battery ever. The rom.
is even smoothest of all the custom roms i have tried. It is weird but Miui Stable release for Redmi 5 plus is a amazing ,

As Per My Thinking Android System Higher Point for Battery Drain In Your Battery Uses Screenshot That Means Some Inbuilt App Use Battery
Ok so i had some problems with my battery draining fast with very little screen on time about 4-5 hours. What i did is opened the phone, disconnected battery cable, left it like that for a minute or two. Then i flashed the latest global miui 10 stable official stable rom using mi flash and flashed all data. Now my battery is once again amazing like when i first bought the phone! I get about 10 hours sot
So I opened the back of my phone and disconnected then reconnected the battery. While the back of the phone was opened, I did the test point method and entered EDL mode. I connected my phone and Windows installed the needed Qualcomm drivers. I opened MiFlash tool to try to flash the latest MIUI global stable ROM, but it always said there was an error. The error was that it couldn't receive the "hello" packet. So, unable to fix this error, I booted the phone and entered fastboot mode then flashed latest global stable ROM. Battery life improved just a tiny bit. Still getting subpar battery life with around 3-4 hours of SoT. Am I missing something or what? I am unable to believe that I managed to damage my phone's battery in less than 10 months since I don't use it for gaming.
Anybody got a clue on what to do?

battery with miui 10

Does any one notice much quicker battery drop with miui 10 update?
I'm experiencing same here.
I just bought the device 2 days and battery on MIUI10 can't even take for the whole day
No issues here. I'm still charging every 3rd day.
My battery is also discharging much faster than miui 9
yep! my phone's battery life has definitely reduced after updating to MIUI 10. Only noticeable if you're a heavy user.
Also, I've noticed now the phone doesn't charge with same speed, while playing PUBG side by.
My battery is much better on miui 10
I agree after miui10 my battery drains faster.( May be %20 percent) .
Now I am waiting for 9.0 and hope it will be turn back to old days.
Haven't tested before, but I reach more than 9h of screen time without no problem on MIUI 10.
Can we go back to MIUI 9.6.14 which is my first version out of the box? Im rooted and TWRP installed. I also have a full backup of my 9.6.14 using TWRP. Can i just restore this image using TWRP? TIA.
Miui 10 beta 8.11.1. Form me is really fine the battery.
I am on LiquidRemix (9.0) rom battery is better than Miui 9 which I was running before. I play you tube 10 mins it discharged 2%.
I think it would be hard to kill this phone on one day with LiquidRemix rom.

With more than 2 days? For me yes. I did 10h of SOT but not in 2 days.
Well not for 2 days, but for 2 days i make around 5:30-6 hours and Mi8 is with 3400mAh. So on Poco should be much better, like AT LEAST 7, 7:30 hours for 2 days.
yes me too
my version is Beta version is there any problem for that in battery
