[Q] High battery drain because of Android-System

Hello,
I have a high battery drain because of "Android System". I lose about 3-5% per hour of my battery in idle state. I turn screen off and didn't use it.
I'm using Slim ICS ROM with franco kernel #174.
Badass Battery shows me that following included processes are in Android-System:
Code:
com.android.systemui
system
android:ui
com.tmobile.themechooser
surfaceflinger
com.android.settings
servicemanager
So anybody know what's the problem here?
I'm already disabled Google Photo Sync, NFC and GPS because I didn't need that. Also googling for the problem doesn't help.
Hope you can help, thanks!

Again, I've mentioned this twice today: Bullsh**, I don't mean to be disshonouring, or anything, but please, give proper answers,. It's all good, that you want to help, but only with proper and correct answers.
Right, back to topic;
Go into your dev. settings, and uncheck everything that doesn't need to be checked (Stay Awake, Strict mode, etc.) Undervolt the CPU, that should save a ton of battery charge, and underclock to 900-920 MHz, that is definitly enough, on a dual-core

Thanks for your answer =)
I think my phone is already undervolted through Smartreflex in francos app and I also tried underclocking by setting max cpu to 1036 Mhz (instead of 1200 Mhz).
The problem disappeared after 1-2 charges (don't ask me why..).
And now after flashing Slim ICS 3.9, battery time seems to be ok (for me at least).
Per hour in idle state the phone consumes ca. 2-3%.
I ask myself how do others get 1% drain over night. Is that even possible? Tried very much kernels (franco, trinity, glados and leankernel) and didn't even get near that.
Any tips?

OP Im glad you mentioned the issues went away after a few charges. this has been an issue for some who do not believe that a few charge cycles does anything. well im with you as i always see things sort of "settle down" after a few days of flashing a new rom.

I have the same problem on my Nexus S.
The process consuming battery is surfaceflinger. I can see it on battery screen before the name change to Android System.

I guess this is an Android problem. Not related to any device.

Android
Yes, i think your prob comes to every Android phone after flashing New rom.
Just wipe Battery stets after flashing. It needs few complete chargings to calibrate the battery.
There are also many apps in the market for this

This. People, just give it 2,3 days for the rom to settle after flash. Same for a kernel.

I don't know if was the new kernel I flashed or was the battery stats wipe I did, but seems now my phone have no more RILD/RILJ wakeclocks.

Yes, it is possible. I get 1 or 2% drain overnight with wifi and mobile data disabled, and up to 5 to 6% if mobile data is enabled overnight.
My record with it is 1 day and 20 hours from 100% to 3%.
I had a LG Optimus Black before and didn't last a day. I'm loving this Galaxy Nexus.

I would like to achieve battery drain like that, seems like what it should be.
I am running AOKP Build 2 and I feel like my battery life is ok but not great. I let my phone sit overnight last night with sync off, but LTE on and it drained roughly 4% an hour. I actually turned off LTE in the middle of the night to see if there would be a difference, and no, it drained at the same speed on 3G as well. I live in an area with pretty good reception actually, GSam says I spend the vast majority of my time with a signal strength of 4/5.
GSam reported that roughly 34% of my battery drain overnight was due to Phone Radio. Another 52% was due to app usage. Drilling into that it tells me that over 40% of the battery drain from apps came from "Android System", "Phone" and "Kernel". Under Android System, which was by far the greatest drain of the apps, it only kept the phone awake 1m18s overnight so that doesn't seem excessive. However, I'm confused as to why, with a good signal/connection my battery would drain at nearly 4% an hour whether connected to LTE or CDMA. Unless the radios in this device are poor, I have a hard time believing there isn't a way to fix this without using something like Juice Defender.
I can't recall because it's been so long, but I don't really remember any ICS ROMs draining this fast. I'm on a clean install of AOKP B2 and I've tried a few different kernels with the same results. Any ideas anyone?

So I wanted to let you all know that after trying a few different ROM/Kernel combinations all with similar idle battery drain, I installed the latest (9/21) CM10 nightly and I only lost about 10-12% overnight last night connected to LTE. That is a much better drain than the 30% or so I was seeing previously. Not sure why but my phone just hasn't been handling the latest AOKP builds very well. I am afraid to try a different kernel right now as I'm leaving town tomorrow for most of the week so I'll leave it as is until I get home next weekend, and see if I get this good of battery life with the latest Leankernel.

Surfaceflinger
The same happens to me, this app appear in BetterBattery stats, Surfaceflinger appear as the culprit of my 45%+ battery consumption caused by Android Sys
When I first rooted my phone (xperia S) I noticed an 31%+ energy consumption by Android Sys, I reflashed and re-rooted and stoped for 2 weeks or so, now 2 days ago I woke up to find that 81% of the battery is being drained by Android Sys, then it lowered to 31-43%. I noticed that when I refreshed the stock "Battery" app ,"Surfaceflinger appear for a moment, I seem that I confirmed with the BetterBatteryStats, Surfacaflinger appears at the top.
Why is this happening? Can something be done about it?
PS: I cannot change kernel, bootloader is locked...

Surfaceflinger and android.process.acore are top battery drainer. I mean how to make them not sucking on battery?

One plus 3 best rom for Screen on time

Can anyone tell me that which is the best rom for screen on time.i am using stock rom.just me a rom that can give a 5+ hour screen on time...i have posted my usage in screenshot

OOS 4.0.2 with OB7 firmware. Then flash render EAS kernal. EAS will make sure that you get the most battery out of your phone.

It doesnt fully depend on the ROM. If u really want good battery life then its all about tweaking. For example flash LOS14.1 with bluspark/ElementalX/Franco then apply a AKT profile, for further explanation of this head to the advanced kernel tweaking thread and then download the akt APK. Then choose which profile u think suits the best. U can choose from battery/balanced/performance. Then u can easily reach 5h SOT. Hope i helped you.

I have 8-9h SOT on sultan's CM13
Screenshots: https://forum.xda-developers.com/showpost.php?p=70828408&postcount=668

Beta 11 with Franco's kernel. 4+ guaranteed SOT for me with a moderate gaming ( CoC and CR .... Both battery hogger )
Plus both Sims and 4g data on one is on mostly.
If you want more battery then you should try AKT ZHANA but for me it made my phone slow. So avoiding it at this moment.
Hope it helps. Thanks!

SOT is personal and doesn't mean a lot you can leave your display on with sync off, 0 Brightness and get 20hrs...
Try different setups maybe ditch some apps and log in with optimized sd browser etc

I have got my best SOT with Slimroms

It really depends on usage more than anything else. For example, I'm consistently getting 5-6h SOT on stock ROM and kernel, no doze tweaks or anything. Never got below 4h, once hit over 9h.

my constant is with 4 hours sot with stock 3.2.8. could be better with 4.0.2 or whatever.. but i stopped thinking about the sot coz its just making me paranoid everytime i look at the battery stats. as long as the phone can hold up till end of the day then im good and as long as i can get off a charger everytime im on low battery then im damn fine

I agree with this as well. I think back to my note 4, and just wanted a better that would last until I got home.. I frequently had to plug it up or swap batteries halfway through the day.
Now with heavier use, [and more knowledge of android] regardless of what I do, my oneplus 3 always makes it through the entire work and school day.

H2OS Beta 7, stock kernel + root +greenify +juice defender(default settings). It's the best battery duration I have with OP3. 5-7h sot generally.

They are talking about unplugged screen time ... I see no other way you could get 12 hours sot from this phone. I'm not calling you a liar just saying I don't think it's possible.

High Kernel (Android OS) & Android System BATTERY CONSUMPTION

I have been suffering this issue since I updated to N (screenshots attached).
Atm, SOT is about 3 hours.
Are you guys experimenting this battery drain caused by this two processes too?
In case this also happened to you. Were you able to solve it?
I installed latest RUU 2 days ago and nothing seems to have improved.

Your kernel and android system usage look OK to me... Google services are OK too IMO. Looks like you've used chrome and YouTube a bit.. Awake time up a little, that would be mainly from apps running in the background. You could try servicely to try and improve that...

It doesn't look ok to me. Comparing it with the phone i use for working, it seems there is a problem in here.
As i was saying, the phone i use for working averages 10% combined kernel+android os consumption while my htc 10 averages 30%+.

I have the exact same issue. I just unplugged my phone and I'm already down 3%.

Why not use Better Battery Stats, let the phone sit idle for 6 hours, download the dump file to your SD, and see what exactly is killing your battery.
There are too many variables to test your device reliably while it's in use. With GSAM, all you see is what's happening while the device is in use, and what 'Eats' your battery, but no 'Why' your battery life is poor, is it background processes/ notifications/ poor reception/ bad Wi-fi??
GSAM creates a guessing game. Logs never lie. If your battery is going bad, it will be reflected in your log(s).

Question Any tips for improving idle battery drain?

Currently trying to squeeze as much battery life from my phone as I can. I'm running arter's kernel and screen on time is pretty good, according to accubattery my idle drain is 0.6% an hour which isn't bad to me by any means but at the moment I'm a little obsessed with improving battery life so any tips are appreciated!

ideally, anything below 0.8 is fine, you should not worry about the idle drain much. There are apps that would underclock the device but it would risk the performance and wake times. You can try that if you wish and see how that affects the device's performance to get to know if its actually worth it.

I considered switching to bluspark since it allows me to switch from schedutil to conservative but I don't know if there's any real world difference between the two in terms of standby drain.

This doesn't include the scenario with AOD enabled, right? I'm getting around 3% idle drain reported by FKM. OOS 11 rooted and with bluspark kernel. Does that sound bad?

Hey all
If I may jump the topic question: I'm on arter97 + derpfest latest + magisk. Today I got like 3h sot
I can't seem to figure out what's wrong... Does anyone know of a working version of bbs for this combo?

Hmm I never use aod. Do you mean 3% an hour? Id expect it to be lower than that but again I've never tester aod.

Yes, per hour. I had between 1.5 and 2% on my previous Realme X2 Pro, and now it's 2.5 to 3%, that's why this looks a bit too high.

Early A12 builds will hog more so cont do much for now. You can use it and see how that makes a difference for you.

No, when I said less than 1% I referred to idle at night time with AOD off when the device sleeps basically. With AOD 2-3% is fine. No need to restrict it further.

Question Miui 14.0.4 stock Battery drain

Hello
I recivied 3 days ago a new update to Miui 14, before update the battery work for 24 hours good (40-50%), now afrer 12 i'ts 20%.
does anyone have this problem?

I am using Miui 14 (xiaomi.eu stable edition), and I also experience battery drainage. I am looking for any updates, but they seem to have dropped their weekly updates for Lisa (the 5G NE). Let's see now, because I ended up liking Miui and not like the UI of any other roms...

yes have the aforementioned problem of battery drain. Since I kept this phone as stock I cannot even revert version

Yes, I've faced the same problem. I was getting 10% overnight battery drain. Then I flashed custom rom(AOSP), and now the overnight battery drain is 4%. MIUI su*ks

On my Mi11 used to get 2-4% battery drain overnight on MiUI13, since i updated to MiUI14 i get 8-14% battery drain, counting i usually sleep 7-5 hours, it's not an issue since i can change fast, but it's goddam annoying that now i consume 15% insted of 10% per Youtube watching hour

One thing could be done is unintall Carrier Services updates.

Any custom rom > stock miui

I've noticed that "com.android.bluetooth" is draining battery. Is there some fix?
