[PROBLEM] High Battery Drain and Lockscreen

Hello,
Recently I noticed that my battery is drained faster than usual, even when I put it untouched overnight, it drains about 30% of battery
First, I thought, that it was kernel (I flashed Hydracore v1.1std), but when I came back to kernel, which I used (Notecore 14.1 std) battery drain still was present.
I discharged battery and charged with AC charger when phone was off, lifetime was increased little bit, but nothing important.
I checked in task manager (es task manager) and there is no unusual tasks or autorun entries...
I cleared cache and dalvik cache from CWM
I checked also cpuspy and my phone does go to deepsleep
also in battery statistics, most battery consumption is as usual order (screen consumes more than 50%) but, drain rate is increased greatly when screen is on (for example when I am using navigation) in comparison as it was before.
I bought phone 3 month ago, so battery itself should be fin
Today I also noticed that screen is not locking after specified time...and I can not figure out which application is preventing it...
currently I am on Hydracorev2.b std kernel and XXLRK stock firmware

First of all notecore is a performance based rom and second did u wiped battery stats wen u charged ur phn completely in switch off mode???

install betterbatterystats and put your phone in airplane mode for a day. Check the BBS after and see any kind of apps or wakelocks that might be causing your battery drain issue.
also,it might be noteworthy to tell you this but your kernel is not optimized for battery life and is instead more on performance (which equates to higher CPU speed consumption and which in turns, drains much battery juice after).
Switch to a more battery saving kernel like SpeedMod... it is developed and mainly optimized to get more juice out of your phone.

Thanks gays for helpful advices
I know, that notecore is good for performance and speedmod for battery life, but as I mentioned battery drain was higher as usual (I am on notecore kernel from v3)
If I wipe battery stats will it help?
I will try betterbatterystats and write results

It will help wipe battery stats

I was running Hydra v1 on LiquidSmooth V2 (beta2) N7000 and using the Beast Kernel. Dropped about 1% per minute while using phone and also about 30% over night.
I then flashed the HydraCore v1 which made a major improvement in performance and battery drain. I loaded HydraCore v2.1 (beta) today and the battery was already a bit better, but I then noticed that the default setting for Latitude was to automatically share my location. I disabled that and so far the battery drain has been less. Will be checking if this caused my issue.

I will update to Hydra 2.1
for now, drain is less than before, I wiped battery stats
here is partial wakelock screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I think this is normal?

I switched to speedmod K3-13
and now, I have deeplsleep issue, and according BBT, this is kernel wakelock multipdp, which drained 97% of my battery (about45% in 7 hours)

I think I found problem:
It's Google Maps Location update service
Code:
com.google.android.location
I found in BetterBatteryStats Alarms over 450 wakeups in 7 hours and almost no deepsleap
But I completely disabled location updates (do not update setting) in Google Maps settings....
any ideas?

Do you have some other apps that connect to the internet as well? facebook, flipboard, instant messaging apps,Accuweather /Clock Widgets... etc... ? You need to individually note all the apps you have on your phone... and one by one check if one or two have some background syncs enabled, turn them off or set it to never.

Thanks for advice,
Yes, I have all af them :| I have disabled location now in all related (FB, Accuweather)
When data connection is on (as it was previous) it consumes a lot of battery power because there is a lot of wakeups and phone is not going in deepsleep (even when in most of applications, sync time is 1 hour (except mail clients)
Now, I have disabled data and after 40 minutes of idle time, battery is still at 100% and most of the time in deepsleep
I will check at morning battery stats and drain level,
If it is OK, I will turn data on and will observe power consumption
But, as I mentioned week age, everything was fine with turned on location services and data
I guess best option would be to flash the rom, but I want to find out what causes problem to avoid it further

you can give it a shot first to observe for a couple of days to let it settle down everything.
And in case you don't know.. your apps are constantly being updated by Google itself. (when you turn data on and access Google Play for example). Some updates on some apps might have triggered this issue. Flashing Roms are just one side to the story. The other side is one big grey matter.

Yeah,
I know this things, at least as user...
Today I turned data, and battery life is greatly improved, it is about 68% at this time, no heavy use, but I had problems with Idle time too...
I also did this:

[Q] Weird "battery drain" when lightly using the phone

Hello !
I just bought my P880 two days ago and everything is great except one thing: battery drain. It is not occouring in background when phone is in Deep sleep, it doesn't lose charge while it's sleeping, but when I just unlock it/start using it, it just starts draining.
I have rooted it, and unrooted using SuperSU. The thing is I haven't experienced that kind of drain yesterday, it was working fine except drain caused by bad signal (badly inserted SIM).
Usage by Android System is at 50% over 5 hours, Screen is at 9%. Awake graphs are the same as Screen on graphs- no wakelocks.
I have these apps installed:
Prey Anti Theft
Skype (not running)
Adobe Reader
SoundHound
Disco Light
QR Droid
Sygic (not running)
X-plore
SwiftKey 3 keyboard
WiFi, GPS, Data, everything turned off except mobile signal
Running Internation version with Android 4.0.3, Kernel 2.6.39.4-00001-g0f9182c
Mobile network type is EDGE:2 with mobile signal -70dBm
I'm first time android user and this is my first problem so I tried to include as much info as possible.
Thanks in advance

I see 2 mayor issues, first is the android deft app, it may be running and trying to sync but bcz the data is off it will try to connect foreva.
Also, edge is (in other words) ROAMING and this forces the antenna to use more power to get signal from another provider, it get worst if you have a phone with sim card.

Thanks for pointing that out, but I have disabled every sync and I have set phone to 2G mode only, the reason is that UMTS signal was low and was draining battery even more.
I am only losing sharge when just doing random things on phone, even if that means only adding/removing widgets/apps on main screen with WiFi off.

Then you must try the Deodexed version of v10f, removing the bloatware with the script in the same thread.
The issue may be some lg apps that are running in the background so doing this will have 6 hours in standby time with 100% still, like me (if I turn all radios off ).

I have just woken up, while sleeping (9h) phone was awake for about 50%, no wakelocks but there were 30 alarms from Android/Google maps ans 29 alarms from com.google.android.gsf
Hope this helps.
I may try custom ROMs if nothing else works.
While typing this message I have lost 7%.

Similar state here as the OP. Got the phone two days ago.
All is good, it rooted OK, Directory Bind works fine, phone runs like hell (about 10 times faster than my old Galaxy S) BUT it drains battery like a genuine power guzzler.
Ok I get that according to the performance you get, it comes with an accordingly high power draw, so I don't ***** about it, I just want to know if this is normal. I mean I played 2 hours and 15 minutes of Sprinkle and the battery died, starting from a full charge. Screen was set at 50%.
GPS is off, Bluetooth is off, no 3G mobile network and screen is at 50% brightness as I said. There's an NFC icon on the notification bar next to the battery icon, which I am not sure if it should be there.
Here are a couple of shots from the battery section of the phone and from Battery monitor widget if these help.

Please note that as the OP said, the phone consumes nearly nothing when idling. Firmware is 10f.
PS I am not trying to hijack the OP's thread. I just noticed the same behavior and I'd like some help on the same matter, as well as to contribute in whatever way I can. If the OP is offended somehow, I will gladly start a new thread.

@psolord No, not offended at all. I'm glad you posted actually.
My phone has encountered 20 more Alarms, wake ups since I left it standing:
com.google.android.apps.maps Wakeups: 50
com.google.android.gsf Wakeups: 45
You can see pictures below, the drop on the second picture happened when I was writing me previous post from P880.
- I am also rooted again (after factory restore)
- I have reenabled 3G networks but the signal is only at about 50%.
Any additional info please ?

Ok buddy, so we can keep discussing it here together.
For the matter at hand, I see the same behavior, when I unlock the screen, it's like I have opened a whole in the battery.
It dropped from 85% to 65% just from downloading a new map (500MB, 20min download on a slow wifi) from Sygic downloader. I mean this can't be right, right?
I also checked cpu spy and it reports the system 75% at deep idle, 15% at 51Mhz and the rest are 0% to 1% up to 1500Mhz. So if the cpu has so little operation, what on earth is draining the battery?
I wonder if we could be looking at a bad battery batch.
Is there an app that reports exactly what activity consumes power and how much?

Indeed, the hole in the battery.
I even restored to factory from recovery mode since I screwed up the root, so it was just stock, but guess what, nothing has changed :crying:
I really hope this can get fixed, else I'll get a replacement.
I hope someone from this forum with more experience can help :/

I think I am onto something.
Can you please check how is the phone doing if you disable everything under location and services?

I am going to try this, I am also talking to LG Support right now. WIll let you know when I get more information.

I disabled everything, and I didn't see pretty much any improvement. LG Support suggested me to return the phone.
Pretty much draining the battery atm so I can charge it back to 100% and use something like Battery Calibration. Maybe it can change something.

Yeah indeed I was onto nothing. Nothing changed for me either.
Playing 30mins of a 720P resulted my battery dropping from 62% to 50%. I also used the gps for the first time with Sygic (Jesus even the GPS is lightning fast) and the battery went from 50% to 30% for a 20 minute ride. It seems that my phone cannot give me more than 2 hours of use. That's just silly.
BTW do you or anybody, know of an app that can show battery usage per app?

Stock application ?
Also you can use Better Battery Stats to see if there are any wakelocks or anything is waking up the phone etc.

What is happening right now is rather strange, I disabled screen turning off (trying to drain battery to 1%/2%) looking at stock battery app, it seems to be stuck at 21% and it's not changing.

The stock application does not do so much analysis, but the batterystats you used above seems more like it.
I am getting panicked and I miss some stuff haha. Ok lets cool.
It makes me sad that we don't get any input from the community. Something like "yeah this is normal, live with it" or "your phone is faulty, take it back to the shop for a replacement" or something.

Agreed, ANY, ANY kind of input would be appreciated, but I guess we are getting none.
I am going to fully charge it today, do some stuff and report back tommorow. Also anyone, please do post any suggestion you may have.

Maybe this has to do something with the built in power saver. Maybe it kicks in when the battery drops to the 20s and stops whatever is draining it.
I am thinking trying some battery saver to see if it does the same thing but from the beginning of the full charge.

Actually I have disabled it when it asked me if it should turn on. So I guess nothing to do with that.

I am going to backup now, fully unroot and somehow get it to pure stock. Than I'm probably going to exchange the phone in case battery life doesn't change.

[Q] Odd battery usage on lg optimus 4x hd

Hello xda-developers,
I'm having some trouble with my lg optimus 4x hd, the battery is mostly drained by the android system, which doesn't normally use a lot of battery.
I would show a screenshot of the battery usage but I can't upload any links yet.
I hope someone else has had this problem and knows how to fix it.
Thanks in advance,
Cas

I'm not sure. This is more like an o4x issue. I had the same: battery usage is 60% Android system, followed by mobile stand by 18% and some more minor percentages.
My Samsung uses most power by use of the display.
So 60% is far too much.
I am trying to find out what I can achieve by rooting and freezing some apps and/or using Greenify. What I hear is that upgrading to Jelly bean causes more trouble.

Airplane mode - causes lots of baseband_xmm_power wakeups
WiFi on when not connected to router - same
Use e.g Tasker to turn on wi-fi when screen is on, and turn off when screen is off. Right now, I have baseband_xmm_power usage at 0.8%, after 16 hours of on time and about 1h 10min screen on. Try experimenting a little more! Using the WiFi>advanced>Keep Wi-Fi on during sleep is not recommended, as it causes a lot of wake locks... :laugh:

I experimented a lot and since yesterday I managed to use less than 10% while asleep. Before that it used 30% or more during the night (about 8 hours).
After disabling a number of processes I can see now that the Android system uses only 12% in stead of 60. The Android Operatingsystem even 2% only. On top is now Mobile Stand-by (42%) en Inactive phone (39%).
This is very satisfying. I did not really documented what I disabled, but now I can root my phone in order to disable things one by one permanently. Because I guess that most of the processes that I disabled will probably be active after rebooting the o4x.

check the first 8 hours of 'doing nothing' cause 30% loss of power
And after:
not complete, but after 8 hours of sleep less than 10% loss of power and the next 90 minutes intensive use - phone calls, twitter, mail....

@xtribas if he's still on 4.0.3 stock, this might be a different issue -- same as mine: 80% of the time a full wakelock held by "com.android.providers.settings" -- nothing seen of baseband_xmm here (though I used a different tool than BBS to check -- will switch-over to BBS next for verification).
@Mauvan mind to tell us what you changed, and how your progress / long-time effects are? As we two seem to share a similar problem, I would be very much interested in your details!

on ICS the baseband wakelock is not present... even so... revert to ICS is not an option for me...

As I did not update yet (stock JB is no option for me, as some of my apps wouldn't work well anymore -- e.g. LBE, and no, the localized Chinese "Master" is no option for me either), there's nothing to revert. But as I wrote: I clearly can see the same issue Mauvan has reported, and am just trying to figure out what that should be. No idea why some "provider settings" should need a "full wakelock" for 12+ hours between ~8am and ~21pm. Funny thing, though: deep sleep is more than the 1h difference to-be-expected, but something > 6h.

@Izzysoft: I upgraded a few days ago to JB and disabled a dozen of programs like Application Manager, Cell Broadcast, some widgets (contacts, memo etc.), Picasa uploader and stuff like that, which I don'use or force Stopping some apps (no permanent solution though).
All these tricks help a little. Yesterday the battery was almost empty after a little more than 15 hours. Not much, because it was not a day of extensive use of my phone.
At this moment I see that my battery load is 72% after 5 hours en 24 minutes.
I'll continue reading forums like this and decide this weekend if it would help to root my phone and look for more permanent solutions. I am not considering Cyanogenmod's rom because there's still no stable version. I've seen great performance improvement of this rom on galaxy s plus, so there is hope.

@Mauvan so you don't remember what you did back on 4.0.3 -- or did you start this thread when already being on JB?
Seeing your numbers, I cannot complain: ~70% is what my 4X goes back on the dock at night, after ~15..16h. Estimated battery time altogether is around 2 days for me (and yes, my device is rooted and I disabled/froze a lot of that stock crap, bloatware and mafia-ware -- e.g. the RemoteCall stuff which does not accept a "No" as answer). Still room for improvement: If I can get hold of that stupid "com.android.providers.settings" WakeLock, I should end up with 80%+ and an overall estimated battery time of 3d+, nice for a weekend in the hills

No, when I started this thread I still had ICS. However, those statistics where too optimistic. After a few hours it went down & down & down. That's why I tried JB. Seems smoother, but drains the same.
Now it's my turn to ask what crap you disabled/froze etc. and what additional apps do you use to achieve that. I would be Very Very happy if my battery time should be, let's say, 24 hours at least.

As not everything is freeze-able from Settings->Apps, I used the friendly Titanium Backup (one of the first paid Android apps I aquired, and never regret) for the remains:
Chrome
E-Mail (believe it or not: even unconfigured it consumed battery by permanently trying to do some Exchange-Stuff!)
Email-Widget
Stock News
Google Play Books
Google Play Movies
Google+
Google Bookmarks Sync (just now, as they ran their sync though I unchecked it in Account & Sync)
LG On-Screen Phone
LGSetupWizard
Live Wallpaper Picker
Maps (using Titaniums freeze/unfreeze widget on my homescreen: unfreeze+start on demand with a single tap, then freeze again with another tap. Must not run in background 24/7/365 when only needed 2-3 times a year
PC Suite Service
PC Suite UI
Remote support service
RemoteCall Service (Mafia! That's the one which did not accept a "No")
Social Networks
Android Live Wallpaper
Today Widget
SmartWorld
World Time
After that, installed Apex Launcher -- and like my phone. Except for that minor juice-sucker

thumbs up! (except I need exchange for workthings)
And did you do anything with the LG-loggings and MLT stuff (hidden menu + apk)?

HiddenMenu I just used to peak into what's available, but did not actually change anything. What I'd like to know is about the LocMgr* stuff: Name suggests a "location service". I couldn't find any information on what it really does (as LocationService usually is included with the Google Apps, this looks like a dupe to me), so I didn't dare to freeze the two. Any idea what it could be about? Or even a reference on what it really is about?

No I'm not sure what it all means and I do not like to experiment in those settings. I've read some threads about the MLT like this one and that one.
In the mean time I just rooted my JB and freezed a bunch of apps. I'll let you know the improvements (I hope!!).

I hope for both (improvements and report)
EDIT: Wow, thanks for the Linx! Read that about MLT:
I just disabled it.. lost the weird battery drain from "Android System" that I've been having lately..
Click to expand...
Click to collapse
Looks like there is my culprit, huh? I just disabled MLT -- let's see how it goes. So now, we both wait for the report of each other LOL

so far so bad
disappointing, because the first night it should be in deep sleep. But instead it consumed 35% in 9 hours. Annoying issue seems to be Cell Standby, responsible for 44% of this drain. Famous wakelock baseband_xmm_power (says BetterBatteryStats).
What I figured out is that there was still one process looking for my location. Wifi disabled in sleepmode, it tried to find access to 3g, but in my house on that place there's not enough coverage (no signal during 56% of total uptime). Might be the age of my sim card? Dunno.
This afternoon I freezed almost all apps like in this link.
Tomorrow I hope to know more.
Edit (17th May):
I rooted my O4X, I installed a root browser, Titanium Backup, SuperSU, BetterBatteryStats.
I watched and monitored. Even tested Tasker (to reduce Cell Standby wake locks). I got a new sim card to replace my (very) old one.
Yes, it improved, but too little. Last night, after so many freezes in Titanium, O4X lost 10% in 8 hours.... doing nothing.
I'm beginning to regret buying this P880. It could be a bad battery, but I doubt it. Too many issues here and elsewhere on the internet about the battery drain.
Also looked at CyanogenMod experiences. This rom gives some people issues like these.
Trade it for an S II plus?

Poor battery performance, what to do?

Hey guys, I'm wondering what can I do to improve my Note 8 battery life. Seems to me that is draining and I do not get the chance to use it too much. Maybe you have an idea how to optimize and track the apps are overusing the battery, so far I was not able to detect which app/component drains my battery. Even Samsung seems that doesn't know since there is no message regarding background processes with heavy usage.
Basically I finished fully charging at 9:15 AM and now 16:15PM time I started to write the post and make the screenshots, it has 16%. What I did all this time with the phone, was:
- a bit of browsing,
- make one NFC payment,
- have the S3 gear connected on bluetooth.
- few twitter messages and viber really small usage. (less than 40 messages overall)
So here are my settings
- WIFI is off and I'm using 3G connection (I stopped LTE thinking that requires more battery.. , correct me if I'm wrong please),
- screen not even on 50% and auto brightness off (using HD+ and a dark theme, everything is so dark!)
- AOD
- no led, no gestures (most of them I turn off for testing purpose)
- Medium battery saver on.
- No phone calls
- few notifications (not more than 20, also the notification is optimized to apps I'm concerned)
Any suggestion how to make it to end of working day .. at least?
I was waiting so long for a new note and now I'm a bit disappointed and I hope that is something I do wrong..
Funny is I just realized that by mistake I put the phone on airplane mode while making the screenshots, still percentage was flying away even like this. I lost 2% making screenshots in a matter of couple of minutes.
Please find the screenshots attached in the link down bellow, were to big to add them to the post.

Thanks!

you might have some apps draining battery. I'm used to a rooted phone, so I'd always check with wakelock detector, but I'm not sure what you can do without installing an app as a system app.
Try factory resetting your phone and using it without installing anything for a day and see what the battery life is like. If it's significantly better, install your apps 1 by 1 until you find out which one is causing unnecessary cpu cycles or wakelocks.

But I wonder, I shouldn't see the heavy usage on the battery info page? Like which app does most of the usage and time spend in the background or CPU?

I had excessive battery drain, about 10-11% an hour with every off . A full factory reset cured the problem.

What's your screen on time usage? 5-6 is probably the normal amount you would get with most phones (This is the most important thing if nothings draining the battery). And yes, it seems you might need a factory reset.

You won't always see this as it could be a byproduct causing a kernel wakelock.
Either way, something is acting incorrectly. The only way to really figure it out is to start over and try things slowly till you find out what it is.
For instance, on my nvidia shield tablet k-1, I was getting horrendous battery life on every single rom, stock or AOSP/Lineage. I found that I was getting 30% wakelock killing ~20% battery life per day when it should be sub 5%. I found that wifi was causing these kernel wakelocks and setting wifi to be disabled with the screen off unless charging fixed the issue entirely.
Now, that anecdote likely has nothing to do with what you're experiencing, but note that you can usually find out what's wrong from trial and error.

I've had my note 8 for 6 days now, and battery life is excellent, i mean i have wi-fi and 4g lte on all the time, bluetooth on all the time, sync with 3 emails, Facebook, weather widget, weather screen refresh every 30mins, location high accuracy, edge lighting, aod schedule 7pm-7am, was 100% at 6am, played games on it lots, used the phone 2x, 1 hour call and a 30 mins call, text messages, it's 130pm and I'm at 55%, try a factory reset then log in to your gmail then just try to update the phone if there is any. Then reboot then start installing your apps. If it doesn't work call carrier customer service and complain about the battery not holding up like some people you know who has note 8. They might replace it with a new one.

Phone died 15-20 minutes after I did the screenshots, so a bit more than 2 hours...
So.. yeah.. I will try a factory reset and start install all the apps bit by bit and see which one causes the troubles.. hopefully is nothing more than that.

Did you restore a backup or did you load your apps fresh from the play store?
I've had horrible luck with issues like battery life restoring from backups. I always install apps fresh.

I did a google restore from backup! Damn! And I was thinking that I should maybe to a clean, one by one app install.

My battery life is also not great but im using full resolution and when i remember time when i got S6 edge on launch....the battery was horrible but after few updates it was perfect so stay strong and wait a bit

can you translate "not great" in hours? :laugh: Because I will say that mine is second after horrible.. with update done.
I will start the reset in a short while and I will test it tomorrow with minimum apps installed.. those which I really must have in a working day..

Maximum 5 hrs on wifi normally about 3-4 battery is not great on note yet....some optimalization would be nice

I use Ampere to monitor the instan drain of current. In a quiet situation (screen on, internet or tapatalk browsing, gear connected, wifi and data turned on) you should have something 200 mA drain.

Maybe some of the settings changes you're making are somehow rendering your phone less efficient.
I have the USA unlocked version and use it as it came without changing to a dark theme or turning anything off and the battery life is much better than yours.

I restored from a helium backup. My battery life wasn't good for about a week but it did last all day down to 20-30% at the end of the day. After a week it has improved maybe due to apps updating. Now I'm at 70-80% at the end of the day with moderate use. I have disabled several apps I didn't need as well.

Seems like it's hit or miss with the battery life. I see a lot of people happy and some are having problems. Hopefully Samsung might push a update to help.

Get cpu spy and verify that your devoce is going into deep sleep when off(mine wasnt at first until i froze/removed some rouge apps). Install accubattery and do a benchmark and see how your battery does. At least do 6 discharge cycles first to see an average. Also, in device maintenance, you can make all apps doze when not being used now.. this is a new feature. Add all of your apps and they get put to sleep immediately. I get 8 hours SOT this way

You dont have to use med battery saver either, just read my reply on this thread and you will be good. You may have to experiment a little to get your device to go into deep sleep when screen off. Mine didnt at first. Its on my other comment

I got back from work and my phone was at 75% that's between 9:30am and 6:30 pm. So my battery life is pretty good. I lose about 5% overnight.

I average 7hrs screen time Got 8hrs yesterday

Question Battery life on my Redmi Note 10 Pro became unexplainably crappy

My phone was purchased a little over a year ago. At first it probably needed a full recharge maybe once per two days, so I doubt it went through more than 200 charge cycles.
The screen on time when new regularly surpassed 12 hours with browsing and some YouTube. I suppose it became a bit worse as time went by, but the current SOT is terrible and also unpredictable. Again, it's mostly browsing on Chrome and YouTube, and it can be between 7 hours SOT to 10 maybe. The MIUI was updated to 13.0.15 I think a couple of months ago, and perhaps it became this bad after the update.
Does anyone else have this? The battery usage breakdown also doesn't make much sense. Chrome is often at the top but it counts as if only a small fraction of its usage was CPU foreground. Android System is often third-fourth, and the Cell Standby can be about 5%, but the drainage when not using the phone is sometimes a few percents every hour.
I revoked almost all of the system apps and also removed "Modify System Settings" for all of them as suggested somewhere, but that doesn't help.
Any solution?

use the dialer and tip *#*#6485#*#*
MF_02: should be the full battery cycle
MF_05: remain capacity in mAh
MF_06: designed capacity in mAh

I have MF_00, 01, 03 and 04 but not those suggested values.
Also, it seems this phone uses a lithium-polymer battery and according to online resources that material is rated for about 300 recharge cycles. Does to mean it's actually expected to degrade significantly after just over a year? I will note there's a battery health status (MB_06) simply saying Good.

Had the same problem, but I bought mine two months ago with global MI 13. Didn't use phone much but Chrome was always on top of the list with minimum to no usage at all. When I disabled Chrome with mi tools, battery was good again. Try debloating with mi tools if you don't have root, should do the trick.

The question is whether it's actually because of Chrome or that there's something inaccurate with the battery readings? I prefer not to disable Chrome.
What SOT do you have with full charges?

To know that. Disable Chrome temporary and use another browser that time.
There could be a good chance that background use of Chrome is because of installed bloatware.

Are there any examples of removing Xiaomi bloatware actually improving battery life?
I know you can't remove Security as it bricks the software and this seems like it might be the one thing that actually uses background battery, but the app is revoked on my phone anyway if that actually does anything.

I know there is a list of removeable Miui bloatware, but because I choose for a custom rom, I don't know of explicit examples.
In the past, with another Xiaomi phone I have done this and I know that this minimized the ads then, but can't remember the BB improvement.
I depends what the bloatware apps tries to do and how.
If they use network connections or cause wakelocks that prevent deep sleep etc. removing them should improve battery life.

I don't have any ads on anything other than regular ads in some third party apps.
Does the debloating method delete or just disable the apps?

You better read the threat about debloating
Without root you can only remove this app for a user.
So in theory the app is gone for you, but it will be still there and is easy to install again.
You need adb for this and can remove/install apps the easy way with a script or manually for every app.
Personally I think you must be conservative with removing system apps to prevent malfunction.

SOT was good, 1st few charges (using from 20-85%) i got between 7h and 8h. I never go to 0 and 100% if i can help it.

On what kind of usage? Because as I said, for light usage I got around 12 hours SOT at first.
EDIT: Ah, you referred to 85% to 20%, that could be around 12 hours for the entire battery.

Something similar happened to me this night. Bought the phone a couple of months ago, currently on miui 13 eea, rooted, sleepy kernel with limited cpu freq. With light usage the minimum SoT i got was 12 hours. However this night battery went from 15 % to 3% and the phone was totally inactive. This is the first time i see this issue. Dont know the cause.

It seems the issue might be a bit better now, as so far the phone has been off the charger for about 5 hours and I have around 92% charge left over 50+ minutes of SOT.
I did "uninstall" through ADB a bunch of built in apps and software as suggested in some bloatware lists, although not everything (and some that weren't suggested in all cases but were supposedly related to mi account stuff), although another thing I did was unlog the mi account from the phone. I think I might have logged it in about a month ago when I wanted to change something with my mi router, and although nothing is set to backup to their cloud perhaps it did work in the background in some ways which heavily drained the battery?
I'll see when the battery is close to 0 what is the actual SOT.

Honestly i don't really know. For example the past night i left my phone on and everything went fine, no drain or strange issues. I always use the battery saver mode and i disabled most of the miui apps with luck patcher, except security, clock and some basic apps

Listen, the change in battery drain after the debloating I did (or just the logging out of the mi account, I don't know) is incredible! As I mentioned, it used to drain almost 20% over a 7-8 hour night with the battery breakdown I pasted above, and now it's 2% to 3% and looks like this:
Makes me wonder what it was doing in the background when all of the optional battery-draining features were supposedly disabled.
