But the problem is i saw nothing on this issue online so im aftaid they wont fix it bacuse they dont know about it

I've seen quite a few post online about poor battery life & other data/Bluetooth issues after updating to emui 10, for both Mate 20 Pro & P30 Pro.
I used the files posted by dog121 (10.0.0.155) but battery life is still great for me as it was on 9.1
I'm sure Huawei will fix the issue with the official (stable) release.

Same problem here, I'm in version 10.0.0.180 but the battery life is still very poor. Disappointing!!!

Mine honestly doesn't have any problem with battery life and i'm on a10 still got 6-7 hours screen on time within 16-20 hours of usage and i'm a really heavy user

No difference noted on battery life since I updated from android 9 to 10 on my Mate 20 Pro...

.
Right for me (mate 20) it was great on version 10.0.0.155 but after the update to 10.0.0.180 battery life is very poor

I'm on A10 with 158 version and have actually observed improvements over version 9.

I am on 180 and battery life sucks. After 3 hours on 60%.
Bought this phone for the exceptional battery life.
Not pleased...

Go to System --> Battery --> Battery Usage to find out what's consuming your power so much. It certainly isn't normal for EMUI 10

For me battery is much better - v. 181

After I updated to .180, my battery is phenomenal. Gained almost 20%, its back to being a 2-day battery phone.

10.0.0.182 - no visible difference.
I will say though that I wiped out the cache partition and it took a few days to calibrate. I did the same as on EMUI 9.1, disable a bunch of system apps, particularly PowerGenie.
Was hoping for better behavior in EMUI 10 but it still stupidly kills apps and notifications...so it's gone.

Which version of firmware was the best in battery life?

Best miui version with best battery backup pure stock

I read some comments that they used to get 8-9hrs of SOT, some said they could manage to get 10 or more hours on SOT, so ive been thinking on creating thread to get some info on what version of miui is the best for battery backup, ive used miui7 and yeah i got 8hrs of SOT back then, miui8 is pretty fast on battery drain, so can i have something on you guys? what version is good on battery backup?
I don't think there's a simple answer to your question. Everyone's use of the phone is different.
Playing games uses more battery than browsing or watching YouTube.
4G uses more battery than 3G.
3G uses more battery than WiFi.
Bad mobile signal uses more battery than good signal.
Setting the brightness higher uses more battery than setting it low.
Overclocking uses more battery than running at stock speed.
MIUI 8 uses more battery than MIUI 7.
So there is really no way to objectively compare SOT between users.
I never managed to empty the battery of my phone in one day, no matter what I was doing.
And as long as you come home in the evening and still have battery left, you shouldn't worry about other people's screen on times.
But do you even need to use MIUI? I have used both MIUI 7 and 8, for many months and I used to think that the user experience was pretty great till I installed an Android 7 rom here from XDA, Slim 7. Only then I understood what a great experience this phone can offer. I have been using Nitrogen OS for close to two months now, and not only does it have all the customization options I need, my phone is smooth as a flagship and I get 10-11 hours of screen on time regularly, with heavy use.
You could use a Marshmallow ROM if you really need a perfectly stable camera, but the camera works 9 out of 10 times anyway.
Custom ROMs are better in every way than MIUI.
Now im on miui7.5.30 battery back up is pretty good. I love aosp based rom but suddenly my fp breaks on NOs, dont know why, since then i get bootloop when i installed custom roms so i settled now in miui
I love aosp to but alarm dont work when turn off phone. And that is important to me.

[Galaxy A40] Battery discharging quickly with Pie - Solution or donwgrade to Oreo

Good afternoon,
I'm new to this forum and I don't know if I'm posting in the appropriate section. Please, relocate my post if necessary.
I'm quite a newbie regarding phone hacks but I can make my way through the various general processes related to phone updates.
I recently updated my Galaxy A40 to Pie (A405FNXXU2ASJ1, Oct. 2019) [update: after checking on the official Samsung website, I updated the original April version of Pie with the August update and the battery issue started aftewards] and the battery started discharging way faster since then. I'm really not satisfied with this issue and I would like to do something to solve or improve battery life.
I tried Package Disable Pro and disabled a few apps and packages, although I don't really know which services to disable exactly. I also added most apps to the standby app list in the developer options, but it didn't improve the situation as much as I expected. I used to charge my phone every 24 hours or so with Wi-Fi on all the time, no Bluetooth or NFC.
Would anyone have an idea to get a similar battery life (charge once per 24 hours) or explain to me how to restore Oreo (downgrade or flash).
Thank you very much for your help
Weird. My Pixel XL is experiencing slightly better battery performance on Pie. I OTA updated from Oreo.

Well, as regards Galaxy A Series, numerous forums evoke a decrease in the battery performances probably due to some bugs in the update energy management pattern.
The problem is that I had to change the phone to night mode and also charge a black theme in order to slow down the battery leakage while in use.

Idle drain issues on custom ROMs

Hello all,
I tried all the custom ROMs available and they seem to have a high idle drain. I am loosing usually 10-20% per day which is extremely high in my opinion.
The Paranoid Android and Arter97's software collection seems to be slightly better but that is Android Pie based.
Is Android 10 the actual problem for the drain? Do you have any suggestions on how to fix it?
I never tried MIUI so I do not know how is the idle drain on the official OS but I had a Lenovo Tab 4 8" plus before and it was barely loosing 1% per day.
I hope I can find a good setup because at the moment there are not many options for a good 8" tablet. Even the Mediapad M6 8.4" is not produced anymore.
Any feedback is welcome. Thanks!
Edit: I forgot to mention that I use f2fs partitions on data and cache. I am not sure if that could cause any issue but on other devices I never noticed battery drain because of it.

yes. I'm facing same issue too. performance is owesome but idle battery got problem. have been try all android 10 for clover. all of them have the same issue . I don't think android 10 causes the problem because my lavender on miui android 10 battery life very good.
Turning off wifi works for me. When I do not need the device I just turn it off and the battery lasts much longer then when idle. have not really looked into it but I guess it is related to data usage or device not going to "deep" sleep
Yes, I had this issue with many custom roms, except Carbon rom. I've been running Carbon rom since I found this rom didn't have that issue, though it has less features than most of other roms

Yup, I second that. Also using carbon rom and idle drain is good
If you're using magisk then v20.4 have higher battery drain during idle. Try v20.3

MIUI 12 strange battery drain

I have noticed that the MIUI 12 version 12.0.1 would have a strangely fast battery drain overall on my mi note 10 lite which I recently purchased. An update for the MIUI 12.02 just rolled in today and has appeared to be a bit kinder on the battery life. Anyone else having battery related issues with MIUI 12 on their mi note 10 lite ? I am really thinking about flashing back to MIUI 11 once my bootloader can be unlocked tomorrow.

I debloated my phone yesterday from all the annoying services of Google as well as Xiaomi ones and particularly the Joyose which is the telemetry and ad service and my battery life has sky rocketed! I will upload screwnshots of the usage shortly.

Allow me also mention that I am on miui 12.0.3 and have also restricted the applications that tend to autostart for no reason. Chrome in particular I uninstalled since it seemed to autostart for no reason frequently.
Same issue on miui 12.0.2
Bought this phone some days ago & battery is not performing as well as it should be considering the phone holds a memoth battery.

Indeed it is pretty strange but in my case de bloating my phone and disabling quite a few Google services helped me. My only issue is that the Other apps power consumption just does not make sense for me being more than 10% which would be the case for my old redmi note 7. Anyways it might be due to dirty flashing although I have factory reset my phone through TWRP the last time I flashed MIUI 12 12.0.3 (xiaomi.eu that is). I don't really want to go back to miui 11.0.5 which seems to be the best miui version battery wise due to some miui 12 features that I like but if no fixes are presented to this on future miui 12 updates I might just have to refrain to flashing miui 11...

Mi9 cepheus SOT (screen on time) ROM battle

Hi guys
I wanna find out which ROM has the best battery consumption with a smooth system.
I'm now on
Havoc 4.3 / 2 years old heavy used mi9 256gb transparent edition / some sys apps freezed / some changings in build.prop / automatic brightness with velis autobrightness
SOT 7 hours in a cycle from starting with 90% charged (using smart charge) used to 3% = 87% consumption in 36 hours
It would be good if you post also the base of your phone.
No one with better values ?

It's useless. You should really test all the ROMs yourself, as our usage differs, our network differs, our ambient temperature differs and so on and they all contribute to battery life or as you expect, SOT.

Hmmm useless?
Ok, I respect your opinion.
In my opinion it's not useless and hopefully for others too, because the main thing is the ROM for overall SOT.
As substantiation the SOT 2 years ago with new phone and Miui factory settings was at the highest value around 3 hours and now I've got 6 hours. Also if I add the ambient temperatures and light and different app using.... the overall SOT now with my old phone is much better as delivered and so the reason is the havoc rom.
It's useless because it can cause misleading conclusion.
There's no such a thing as overall SOT for everybody at least without perfect comparison (i.e. you list all your phone age, apps, settings and usage pattern) with previous ROM you use.
Even if your experience above is true, there's no guarantee it will happen to me as well if I also change ROM. For starters, my MIUI EU ROM ever since I had this phone 1.5 years ago has always been around 5-6 hours SOT. That one alone is already different from you, right? I would be very misled if I think "oh, this person can jump its SOT from 3 hours to 6 by using havoc ROM, so if I follow him I could get 10-12 hours, or at least 8-9 hours". Don't get me wrong, ROM does have influence to battery life, at least if the developer do some low level optimizations, better if at kernel level, but still assuming one person's experience can be reproduced by others, is a no go.
My best experience is with stable xiaomi.eu, 12.0.6 at the moment, and about 20 frozen MIUI and Google apps. I test and use custom roms from time to time, but never had better SOT than with xiaomi.eu and the same package of apps.

H, since I updated from miui 10 to miui 11 and even now that I have miui 12 I have noticed that the battery doesn't last as long as before. I state that since I purchased the phone (July 2019) I have always charged the battery in the best way...

You can usa AdbFastboolTools with debug USB to disable system apps.
