Hello,
Since a few weeks, my xiaomi a1 can last only 4 h SOT with a 100% battery.
I tried to switch kernel, to switch different roms (RR, AIM, Pixel Experience) and even to downgrade to Android nougat. Between all version switch I wiped ALL the memory...
I even tried to calibrate battery, by a full discharge and full charge, and by the "root method" (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=fr)
I don't have a huge usage of my smartphone, small social networks, music and web browsing. With the same usage I had 8h SOT before.
I don't know what to do... I start to think that my mi a1 has an hardware problem, what do you think ?
A kernel shows its effect after 2-3 cycles . so make sure to stick to a kernel for 2-3 cycles
I had big battery drain on my Stock Mi A1, overnight it was draining 20%. My problem was with WiFi router. Wireless was set to Channel 1, I changed it to Channel 6 and now there is 1-2% overnight drain and I can get 2 days without charging. Check what Channel is set for your WiFi if you're using it, and then set it manually to Channel 6

Can you tell me how to change the channel
I too sometimes get 4 hours of SoT until 30%, other times it does more or less.. so I guess it also depends a lot on how we use our device..

Depends on what router you use. You will need to login to your router, then find wireless settings and there will be Channel option, probably set to Auto, change it manually to channel 6. Find how to do it on Google or YouTube.
Thx to you for your answers.
I tried the customs roms and kernel for at least one week before change...
I know all depends of the usage but here, with the same parameters and usage I went to 8h+ SOT to ~4h, and many wipes and software change have not resolved the issue.
I will try to post you a screenshot nextly
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 Xiaomi Mi 8'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!
Hi all, i use china rom and i can show you how los is draining when idle( the phone was in my night table) overnight.
I would say there's a 15 -20% drain overnight, I've had my Mi 8 for about a month.
9.5.11.0 Rom

That's terrible. I moved to 9.5.13 Global and my drain was about 3% last night.

Yeah no problems with drain here either, run xiaomi.eu MIUI 10.
My bootloader is locked. I can't install other roms. My main concern isn't the battery drain however as it charges up so damn fast. I have GPS issues, it's really slow and it constantly gets turned off despite given all permissions for google maps.
3-8% drain over the night
Chinese rom: 9.5.11.0
Hi, I have xiaomi.eu 10.10.18 rom and I have I think serious drain. In GSam it looks like this. Anybody else have that RCS phone app using that much juice?
There's big problem with cell standby brain on this phone!!
yeah, also on xiaomi EU 10.1.2 and got problems with cell standby.... it takes around 21%.....
5-7% overnight on global beta 8.12.20, network mode set to LTE/wcdma and adaptive battery enabled.
Always on display enabled

The cell standby is not a direct reflection of the power drain, it only shows the proportion of battery usage compared to other components. e.g. if you have the screen on for long time, then the cell standby for the same period will be relatively small.
You can check out from my test. My phone can have cell standby of 34%, but the battery only drops less than 2% overnight! I'm on Global Stable v10.1.2.0 through OTA update.
Yes, posting screenshots of your battery usage without mentioning or also posting screen on time is completely useless.
Mobile standby dropped for me with similar or less amount of SOT after switching network mode.
Miui Global 10.1 Stable 10.1.1.0 (PEAMIFI)
Battery lasts more than 3 days with these settings.
If i let wifi on, it drains 15-20% while i sleep.
Preferred network type = 3G
Wifi, bluetooth, gps are off when not in use.
Debloated using MIUI 10 De-bloat (Then i installed Google Phone,Contacts,Messages)
Facebook,youtube,9gag vs.. for these kind of apps, i go to their mobile websites in chrome and use "Add to home screen"
Installed Greenify, i actully dont know if this app makes any difference.
Alot better battery on custom rom
When I was using MIUI 10 Oreo battery was great between 8:30h and 10h SOT then I updated to pie and man what a horrible mistake battery came down to 6:30h 7:30h SOT, now I'm using pixel experience and getting between 8:15 to 9h SOT.
Since Xiaomi isn't responding to the Bug thread on MIUI forums:
https://twitter.com/_Princeps_/status/1082926593331343360
Please retweet this if you have an account so we'll maybe get a fix for all these MI 8 battery issues.
9% drain in 7 hrs by night, 2-day total radio stand-by drain 15%
I get 9% (too much) discharge in 7h by night (wifi and LTE radio on) while I sleep, no display use and most apps shut down, and few wakelocks (0.5% total time). Something's wrong with the radio. I am on LTE/UMTS auto (PRN), 9.1.3 EU, Sphynx kernel. Radio usage is 38%, and Wifi 5%. I get full bars of LTE at 1815MHz band 3 (Net Monster RSSI -59 dBm, RSRP -87dBm). NetGuru reports driver bug and won't start.
When I set Airplane mode or turn off the phone by night discharge is minimal (~3%).
In more than 2 days on battery with intense screen use (14h SOT), total standby-drain is 15% (too much), and display drain is 26%. Wifi and radio was on most of time.
¿What's the conclusion? This phone drains on stand-by. Battery life is good in general, but stand-by should be less than 9% in 7 hours, I'm sorry.
P.D.: I will try Syberia rom, maybe we need updated kernel with better radio drivers...
The conclusion is that the baseband is ****ed.
There's all kinds of weird stuff hapening and it appears that at least one of the issues is that the MI 8 will always follow the MIUI/Android configured network mode instead of the SIM card overriding regional differences.
Lemme copypasta my own post from the MIUI/Xiaomi.eu forums:
My initial tests regarding the Network Mode on the MI 8 are on page 2 of this thread. To narrow this down I ran similar tests on my Redmi Note 4X to find out if other devices handle it better and it does appear to be so.
MIDO battery drain with Network Mode manually set to LTE/WCDMA instead of the MIUI default value of LTE/TD-SCDMA/UMTS was exactly the same.
But the cell signal history wasn't...
Redmi Note 4X, Xiaomi.eu 9.5, 70km Highway drive with Waze and internet music stream running, fixed display brightness. Same route in both tests, just opposite directions - hence me flipping 2nd signal history in the following screenshot:
I then went and checked what would happen if the network mode was manually set to "TD-SCDMA only"
Mi 8 @ global beta 8.12.20 set to "td-scdma only" : NO CONNECTION!! MI 8 just keeps searching for TD-SCDMA cells and doesn't find any.
Could be another hint that our mi8 is reacting adverse to the lte/td-scdma/umts default setting... the SIM card should override this setting.
Redmi Note 4x @ xiaomi.eu stable 9.5.2.0 set to "td-scdma only": no effect, it'll stay on whichever network mode it was set to before. This is good since it means the SIM card is reacting and working correctly and overrides or ignores the wrong configuration
Redmi Note 4x @ xiaomi.eu weekly 9.1.3 set to "td-scdma only": no effect, stays on same mode as before. same behaviour as stable 9.5.2.0

This also means that 2G fallback just doesn't work for me because there's no LTE/WCMDA/GSM setting available. That stuff is kinda hard to troubleshoot but I went to a spot that has very bad 4G reception, no 3G at all, but acceptable 2G.
Went through almost all network modes and the only instances where it'd succesfully fall back to GSM/Edge was when set to GSM only, TD-SCDMA/GSM (useless) or LTE/TD-SCDMA/GSM (also useless because then you get no 3G)
Interestingly, I have analysed the wakelocks by night, and even if they don't add much to battery, some of them seem to be Xiaomi's metric apps that 'report to base' every 2-3 hours and wake-up the phone 133 times more than Whatsapp, Messenger and GooglePlay.....
Oh yeah uninstalling those metrics apps surely helps with standby drain.
Someone posted the short guide a couple weeks ago....had forgot about that:
https://forum.xda-developers.com/mi-8/help/extremely-battery-drain-miui-10-stable-t3843702/page4
That certainly helped lowering "Android System" drain. They'll stay uninstalled after updates and will only reappear after a factory reset.
Hey guys, on which firmware are you getting the most of your battery life ? I'm suffering battery drain on Android Oreo and even on Android 7.0 firmware 14.02.1712.29 . Tried turning power saver mode on, disabled auto-start apps, brightness level at 50%, no push notifications, no auto-sync, no location service.
Hello,
Just got brand new Xiaomi Redmi 7a (3 days ago) and it's superb except one thing... it's battery sucks :/
I'm using it only for calls and sms. My WIFI is off, auto sync is off, BT is off but stil my SOT is only about 2 hrs :/
I'm using MIUI GLOBAL EU, tried MIUI 10 (10.5.2.0) and 11 (11.0.18)
The most power consuming thing I found is "Android System" it took about 70% of all my battery is it normal ?
I've read that this phone has superior battery :/
I can't place my screen picture I'm to fresh user here :/
plz help
------------------------------- solved ------------------------------------------------
OK I solved it, used "Debloater by The4Anoni"
link: https://forum.xda-developers.com/android/development/miui-xiaomi-global-debloater-the4anoni-t3879739
And now my 7a consumes aboud 15% battery per day
