Mi 10 Lite overnight battery drain on MIUI 12 - Xiaomi Mi 10 Lite Questions & Answers

I recently got a Mi 10 Lite and the battery seems to drain about 20% every night which seems very excessive to me. Last night for example it was on 71% when I went to sleep at 12 am and woke up 7 hours later to see it on 50%. I installed Battery Guru to help give more insight as I don't think MIUI's battery stats are the most accurate and it seems Xiaomi's security center is sitting at the top with 72% battery usage. This seems very high to me.
I do have a pi hole server on my network so is it possible that something on my phone is trying to phone home and can't get through?
The only thing that is on at night is wifi - GPS, bluetooth even 5G is off.
Has anyone experienced this on their device? I know I can try a Xiaomi.eu rom but I wanted to keep things as stock as possible for sometime.
I am wondering what else I can try?

I updated mine to Global 12.0.3 last week and mine seems to be losing a lot of battery overnight. Sync is turned off and there's minimal apps on my phone anyway. Mine seem to lose 20-30% overnight and it didn't before i updated.

Mine has lost 9% since it turned on at 7am this morning - so 8 1/2 hours. I'll leave it on overnight tonight, but your loss does seem excessive. I'm also on 12.0.3 Global.

Did a bit of an experiment last night. Put my phone on airplane mode and then turned WiFi back on. My phone only lost 2% battery during 8 hours overnight. I understand the cell radio uses a fair bit of battery but I wouldn't have thought 20% in 8 hours overnight in standby.
Is it possibly my sim card that might need updating, it is 4 or 5 years old? Unless it's just MIUI12 that doesn't play well with certain radios? Either way it definitely seems to be a radio issue.
I have noticed that when it's in standby for a long time with the cell on the MIUI Security Center jumps to the top of the battery list with a very high percentage of battery usage. Every time. Not sure what that would be.
Very frustrating. Maybe I should try a hard reset.

Mine has lost 30% in 36 hours, everything turned on except 5G as I'm nowhere near a 5G signal. Which seems about right for my normal usage.

When you updated to MIUI 12 did you do a reset after the update or just a straight update?

MIUI 12 was released within a few days of me getting the handset - I don't remember doing a hard reset, but it is possible. Definitely didn't after the newest update to 12.0.3 though.

why does your battery stats screen look different?
Oh and if I use the phone with light browsing/videos/music it can go for 5 maybe 6 days with the Gingerbread update and Mugen 4500 mAh extended battery. I got 3 days and was still at 68%.
To be completely honest, my battery life hasn't been very good lately. I'll take it off the charger at about 7AM in the morning. It'll be about nearly dead (in the orange or red) at about 6-8PM. Before the update, i'd get a lot more life out of it honestly. Whether I was using it or not.
i'm at 78% after 17hrs right now. but i utilize wifi.

had exact same experience. I've decided it's because while I'm on wifi at work, it's not a strong signal so the phone keeps dis/reconnecting.
I'd say that I generally get around 20 hours with normal weekday usage.
I installed xboarders tweaked with LG cam and nothing else and would get about 10hrs out of the battery. Then I installed the nontweaked version with all bloat and stock camera and when I put it on my charger I was at 30hrs with 28% left.
If you wanna feel good about yourself dl ZDbox ... it always seems to exaggerate my battery life...lol
With heavy use I get about 8 hours.

Since I installed this plain rooted rom my battery has flatlined. All I have installed on it is Beautiful Widgets and enabled wifi calling.
has anyone ever seen anything like this? 15hrs and it was still at 76%.....
My battery was horrible until yesterday. CM7 build 97 helps my battery a lot and then I also use SetCPU with a screen off profile and an in-call profile. Those 2 things left my battery at 7% after exactly 24hours off the charger and light to moderate usage.
Screen off - 312/216
In Call - 1000/216 with priority slider set higher that screen off profile.
Credit goes to 'phburks' for the profile settings.

Dude you didnt even use the phone until the end where it dipped.
Yeah, isn't that what your looking for? I only want my battery to drop when in use. Every other rom I have tried the that slope has been at around a 45° angle.

I've gotten better battery performance on Eagleblood 2.3.5 ver1.6
Overall, still sucks. I've not tested the battery because I accept that having android, I can't expect for more than a day's use. My nokia e72 has great battery performance.
I'll push to see how much I can get, but honestly, I accept it. I'm always near a charger so it doesn't matter. Spent most of my frustration on getting a working ROM with my phone.
Now I can tweak with battery performance. I don't expect anything more than 8 hours. I use my phone alot.
last full charge on my G2x with Faux's rom and UV kernal lasted me 55 hours with normal usage, H+ (3g+) most the time, the true 42mb 4g isnt out here yet
I got 12 hours today. Amazing.

[Q] Help with identifying Nexus S i9020a Battery Drain

Running Stock ICS 4.1.2 on Nexus S i9020A on AT&T US.
The battery was fine till about a few months back, but of late, it is draining @ around 8-10% per hour on standby!. I originally thought JB was causing the drain, and switched to ICS, and finally to GB. But the drain is consistent across all three.
There is also accelerated battery drain if my phone is completely switched off. If I leave the battery in the phone after powering off, the battery goes from 100 - 0 in less than 4 hours. Thinking the battery might have gone bad, I bought another oem battery, but that is exhibiting the same behavior.
This leads me to think there might be a hardware issue with my phone. I am tired of keeping the phone plugged in at all times, and am ready to throw this out the window and get another phone. As a last ditch effort, I wanted to post this here to see if I can get any kind of feedback/confirmation on this before I buy another phone. Other users are reporting 1-2% battery drain on standby, so 8-10% drain is unacceptable by any standard.
I have attached some screenshots from today when the battery was at 20% after about 9 hours. For this test, I did the following last night:
1. uninstalled all apps I downloaded
2. turned off WiFi, Bluetooth, GPS, sync, auto brightness ( set to the minimum brightness)
I charged the phone fully, and then left it on standby, with minimal usage - I think I made a 2 minute call, checked my email once, and read some rss feeds for about 5 minutes in the 9 hours I tested it.

Any help would be much appreciated.
Thanks!
I know I'm not giving any advice here but I just wanted to let you know I'm in the same boat. No matter what ROM GB/ICS/JB I lose too much battery per hour with the phone just on standby. There's no explanation for %10 battery drain per hour with pretty much everything off (wifi, data, gps, nfc, background data, etc)
I have tried everything and now I must admit I've given up. I'm just going to ride out CM 10.1 until I can decide on a new phone, most likely the Nexus 4 or HTC One.

Bro, just replace the battery, buy a new one!
Doesn't seem like a software issue to me, sadly.
That confirms my suspicion. I guess it is time to start looking for a new phone. Thanks!

Yeah, your phone doesn't seem to be doing much while asleep. 20 minutes screen on, 35 minutes active, yet battery down to 21%. My battery would be at 90% with that sort of usage. Since you changed the battery (I'll assume it's a decent quality battery, although a cheap battery could be in cause), there's not much left.
Have you tried switching 3G off? 3G seems to SUCK the life out of these Nexus S batteries like no tomorrow.
But I suspect it's a hardware issue with the Nexus S phones. I have WiFi, Bluetooth, 3G and auto-sync all shut off and a static wallpaper and I will lose 20% of my battery in 7-8 hours.
Battery is kernel related. Try changing your I/o scheduler to row and governor to smartassv2. If you don't have those options then look for a kernel that does...air kernel and matrix should suffice.
NO SOLUTION so far
A friend was having the same issue, gave him the battery of my nexus s ... it lasted him for 7-8hrs max whereas it gives me 1 day~ on 2G and normal use without gaimng . So my guess like his mobile your mobile may have some component which is short and draining out the battery . I have been trying to look around for answer but so far no luck. So better check it with another batteryif you can before purchasing a new one.
Vampire test
If anyone is investigating why their Nexus S suddenly starts draining the battery in a matter of hours, BEFORE spending a ton of time (like I did) trying to diagnose what software problem you might have, do the vampire test, as described here:
http://forum.xda-developers.com/showthread.php?p=42586314
I wasted days before coming across this test on this forum, and it proved it had to be a hardware fault.
I have two healthy batteries, both hold a charge for days (probably weeks) when not inserted in the phone, but pop one in the phone, leave it powered off, and within 6 hrs it's dead. So frustrating, and sad to see this phone go.

OPO battery drops dramatically after the last OTA

After installing CM13.1-ZNH2KAS254 the battery lasts only four to five hours by merely using the phone.

- How many full cycles have you had since updating?
- Are you using the original OPO charger and USB?, aftermarket products don't offer the same charge rates so may affect battery use.
- You have a device that is 2 years old, the battery regardless of it's total charging cycles is already past its 12 month expected lifespan.
- Try clearing the cache via recovery, this is something always recommended after an update, regardless of how small as it irons out any duplicates or issues.
I bought the phone this year, I am using the original charger and cable, but I have been charging it whenever I had the chance because of my work. For example from 35% to 80%, never letting the battery drain out completely. I contacted OnePlus and they advised me to let it shut down and full charge the phone three times. I will post the resaults.
I also use tethering a lot, at home on my desktop pc. I see that while tethering is on, the phone is charging really slow, like 1-2% every 10 minutes. Could this be linked to the battery lifespan?

This is a known issue of slow charging with the latest official update. If you are rooted the device, you can switch to Custom ROM like sultanxda's which does not suffer from slow charging.
Battery life actually depends on how you use the device. If you just use the device to read, it'll last longer. If you use the device only on WiFi, it'll last longer. If you have good network coverage, it will last little longer and most important is the age of the device.
Battery drain can be because of some of the apps using the device resources(like Google Play Services etc) continuously and not allowing the device to go into deep sleep mode.
Tethering drains a lot of battery as your device acts as a router and gets the power from the battery

This is a common issue on MM roms and the OPO.
Lots of people are reporting wacko battery behavior after upgrading to MM.
In my experiments, the CM 13.1 by Sultanxda was the least offending, and possibly COS, but I don't exactly remember about COS.
Switching back to LP will correct any battery issues.
What about screen overlay which is very frustrating.

It's been almost 1.5 years since I'm using my OPO.
With the latest COS update, battery backup hasn't changed anything toward bad if not better.
6-6.5 hours SOT always based on my usage. While I get under 5.5 hours SOT with similar tweaks using SultanXDA CM e.g.
COS 13.1 is running really good for me, battery is great, and honestly, since COS 13 came out, I've literally stopped using custom ROMs while on COS 12/12.1 I was barely using the official ROM. Mostly was on Resurrection Remix.
So battery backup wise, COS is "GREAT" if you know what to tweak, and yes the phone charges from 1%-100% in 1.5 hours using the stock charger.
Do a battery calibration, complete calibration, here's what I do after every flash, drain to sub 1% when phone turns off, go to recovery and keep it there until it "completely drains itself to death", then start charging from complete zero all the way up to 100%. That works for me, can't take any guaranty for your device though.
[SOLVED]
I did what they suggested and the battery lasted a full day, 08:00 to 02:00.

S10E stand-by battery drain. Let's get on top of this.

So, I have a Exynos variant of the S10E and I'm having mixed result with battery life:
If I use my phone a lot (and I mean a lot) for example when I'm traveling i get about 6 hours of SoT which is great with a 3.100mah battery and heavy usage.
However on a regular day the phone just seems to discharge itself when in standby mode and I don't even reach 3 hours of SoT.
My setup is simple: all apps are disabled when on standby except for WhatsApp, Telegram and some e-commerce stuff and in the Battery stats "Android OS" in on top of everything (except for screen).
Are you having the same issue? Did you manage to find the cause? Let's discuss it.
This solution was posted on the S10 forum and certainly helped me.
There's a bug that stops the phone from going into a deep sleep mode post making a call (audio/video) on apps like WhatsApp, Skype et al. The solution for the time being is to reboot the phone once before going to bed. I tried a lot of other things but had a ~2% hourly standby drain which reduced to <5% overnight after figuring out this solution. I have both WiFi and Bluetooth on at night.
You may try to play around with the battery saving tweaks in ONE UI but nothing worked as well as this has. Hopefully there'll be a more practical fix to this soon.
Cheers!
Hi! Thanks for your feedback.
I have my S10E scheduled to reboot every night but this doesn't seem to fix the issue and I also don't use whatsapp/telegram voice/video calls, so I don't think is is quite the issue.
There's probably something else preventing deep sleep, but I think that waiting for an update from Samsung will be my best bet

That's interesting. There are over two dozen people on the s10 page confirming this to have solved their drain.
For how many days have you had your device? Mine took a while to understand my usage pattern
I am currently getting over 5 hours SoT over 18-20 hours now, it was ~3 hours previously.
I'm having the same issue. No video calls and still losing ~2% per hour. Restart doesn't help.
Mine too, lost 3% in under an hour sitting in my pocket doing nothing. As usual the battery stats are not much use.

There's a bug with the proximity sensor. The phone gets turned on automatically in the pocket which might cause battery drain.
BTW putting the phone on battery saver (Medium power saving) mode stops battery drain. Until we get a fix from Samsung this seems like a worthy option.

Nope. It's not only when sitting in the pocket. Basically put it on a table and the battery will drain.
There's people on the S10 forum reporting a much better battery performance after a software update (ASC8) on the Exynos S10 / S10+ (see here or here) that should fix the drain issues. Do you know if they are rolling it out also for the S10e Exynos?

It seems ASC8 has been stopped, and they are releasing ASCA. For now it has only released for Germany firmwares. Let's see what's new in this update. Regards
Same issue
I have the same problem, when phone is in use it gets great SoT of around 6 hours, but when not in use throughout the day battery still drains very quickly. I was hoping the update will fix it , but even after updating, nothing changed. Hopefully there is a solution soon.
Seems like battery drain issue was fixed in the latest update ASCA. Mine was previously draining 15% overnight. Now it only drained 4% in 8 hours!! Which is pretty amazing.
Anyone have the Hong Kong model G9700? I've noticed standby drain is quite high.
I have German ASCA version, but battery is draining awfully. I use both SIM cards and loose 25 percent half a day being in standby-mode.

Expected at least 5 hours of SOT from a phone at this price point. This is bad. Even with the second sim turned off, battery drains heavily.

I was also having pretty bad battery drain, 15% overnight. But after the ASCA update I'm getting about 5% overnight, maybe it's just my phone?
Used this guide:

After i made the tweaks the standby is decent compared to my OP6
I disabled bixby on the Maine screen 4 hours ago and I do have a feeling my battery od much better. Will see...
ASDA update seems to help with drainage for me.
Using 970U1 TMB version. Attached is typical usage for me last few days. I get another 6-8 hours sot average by 15% or so and about ~5% overnight drain
S10e Weird 999:MAILBOX_CP2AP Wakelock
Not sure why the "Android OS" always so high usage, I think in normal case, it should be lower than "Android System"..
And by using Battery Historian, I saw this kernel wake up, does anyone knows what's that?
I'm having a lot of RILJ_ACK_WL too.. Sigh.

Mine's not too bad but then I have a choke-chain on it so to speak. #1 thing imo is to restrict google gms and use aggressive doze settings, allowing the occasional 'maintenance' sync thru wifi (set to turn off at screen-off). Naptime may be oldish but he keeps it working...esp his magisk module for dozing google! BetterBatteryStat has now been updated for A13 and more! Battery Guru is also a gem. If ur not rooted, u still have adb perms for BG and BBS to help. I also don't have much of any 5G connectivity so I changed network pref. to 4G/LTE.

I'm not rooted.
How would BBS or BG help with the draining?
And is Naptime effective without root?
BBS doesn't 'do' much but it's a great tool to see what's using batt., how much and when...incl. details of any wake-locks that may be keeping your phone from entering/staying in dozie/deep sleep. It can give you percentages starting at boot, unplug, last full charge (variable) and almost anything u could want. With ADB perms., you don't miss out on much vs. root. BG is just a good all-round battery app. that can also keep charge session stats and set an alarm for what min/max charge levels but can't actually stop charging...just an alarm so u can keep from maxing to 100% every time...extends batt. longevity big time. I'll try n find some good links that explain the dynamics muuch better than I can...
I'm happy with battery stats. I use Battery Guru to check, but it usually reports 15-30 minutes extra SOT than system settings. Either is very good. Stock with no root, still December. Last few SOTs:
010623 10h 18m 100 to 10
010723 11h 35m 100 to 8
010923 11h 10m 100 to 8
011123 10h 57m 100 to 0
011323 10h 53m 100 to 10
011423 11h 56m 100 to 10
011823 10h 28m 100 to 7
012023 10h 46m 100 to 10

is it safe to let the battery get so low before charging ? i thought it shouldn't go below 20% or is that a bit of a myth
I've gone from 100 to 10 with my 4a and 6a since day 1. I've never noticed battery depletion other than an oddball app hit.

In terms of longevity of the battery itself (battery health), as opposed to battery drain, many people think that not letting your battery get below 20% and not charging above 80% is the way to go. Also, frequent, shorter charges are better than longer charges for the battery health, according to many of these same people.
The way I charge depends on how long I intend to keep the phone. I usually shoot for a once every 2 year update cycle. Since I'm not a super heavy phone user and don't plan to keep phones more than 2 yrs...I've adopted a 90% max and 15% min charge strategy. Heavy users or those planning to keep their phone like 3 or 4yrs may want to stick to 80%/20% or somewhere in between.
Here is a great write-up on best charging practices.
How to maximize battery life: Charging habits and other tips
If you've ever wondered what the best way to charge your battery is, here are some scientifically proven tips for maximizing battery life.

slightly off topic again but following the battery care theme .. car ( lithium ) batteries .. 20-80% to prolong their life span ( How to get the most out of your electric car battery article ) , so i suppose the same principle applies across the board .
thanks everyone , who says ya can't teach an old dog new tricks
Could battery saver Itself be the issue? I received the update and do not have any battery issues or idle drain..
Battery saver is off - how ironic
Not sure, I have the battery saver on and DO have the drainage issue.
I got it in the UK , unlocked global , and a list of updates from Google January updated models. Nothing about battery fix / issues ..

Mine still has not seen the Jan update. At this point, with the Feb update coming out early, the 6a might just skip Jan entirely.
Link seems to imply its mostly just the 5g drain issue thats been around since release. Sometimes blamed on the type of modem google is using or the software around it.
My 5g stays off unless if i'm signal searching. With it on the phone seems to try too hard to connect to iffy 5g instead of going with a stable LTE.
I actually turned 5G off, unless I'm going to be streaming.
CAn't be since mine's on Wifi most of the time and I have the drain
