[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

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.

[Battery Life] OP3 vs IP6

Hi! I know Android since 2008 (HTC Hero), had tons of devices and (have to) use IPhone6 Plus for work.
Can someone please explain why IPhone is basically not draining battery when screen is off? I can put my IPhone with all services running...Facebook, email, Google, Instagram etc...If I dont use it 24h it maybe looses 3%...
But on Android...not matter what I do (Greenify, disabling notifications for Facebook, Instagram... etc..) I don't get anything close to that. I discovered across multiple devices with different ROMS. With my fresh OP3T it is not any different...
What is Apple doing differently here?

Google has more services that sync in the background than apple by default, so things like location history (which I would recommend turning off) and sync for apps like Facebook that can't be disabled (unless you use Greenify) are the most common drains.

I know But even if I change massively on Android incl. Wakelocks etc there is not a lot of change. Facebook I had e.g. on Cyanogenmod as "keep active = no" and others as well...But IP was still way much better. And I get all updates on my IP6 incl. ebay, messages etc....
Honestly it is annoying because stand by drain should be at least the same with all the measures we can do with a rooted device...but in reality IPhone keeps e.g. 100% for at least 8 or 10 hours....
I know location history has definetly some influence...is there any way to send location history maybe only every 10 min?

That's all due to optimization of the app code and the os

Set localization to battery saving mode, and you should get better results on Android. IOS is better optimized though so you wont get the same results on android. Also if you suggest on battery stats you shouldnt comaper androids SoT and ios "device active" or something because they are not the same.

I know it's really bad. Look at my results. Can't even run for half day on battery

If you want really disgusting battery life, give the moto z play a try. My wife got one recently and it is unbelievable. +10 hours SOT over 48 hours with sync on and no battery saving techniques. It's only got a 3500 mah battery, which leads me to believe CPU efficiency plays a bigger role in battery life than optimization of the OS.

Because your device doesn't sleep, if it sleeps (screen is off) the battery drain should be way closer to a solid line that barely goes 1-2% down. Buy you are ilon Nougat CM 14.1? It's known that sleep is currently broken on 7.1 Nougat for Oneplus 3.

I think there is something really draining your battery or your battery is dieing.
Look here cb 8.
Download betterbatterystats this should give you a clear view what is the cause. Here an average drain of 1.7% per hour.

Hi I have better battery stats installed nothing significant in there too. I am. Running 4g all the time may be that's why the drain is so bad

thank you for all the feedbacks. Just wanted to start discussion about it!
Real life experience with my work iphone 6plus yesterday.
3% at 8pm...sync and all services on (gmail, location for google, facebook, ebay, instagram etc...) and running. Phone was ringing twice because of skype call coming in, but was not used...Next morning 7am still at 2%....
Android got better, much better, but still is far from that....pretty much the only part I like about IP

ip6?!?..
It's that a phone?!?..:laugh:

The Iphone has better battery life, easily.
However, the battery life on this phone is such that it shouldn't be a problem... Who goes a day or two without access to a charger?
If you are doing nothing but watch Netflix and play Pokemon all day, yeah, the OP3 will run out of juice... But at that point you don't have a social life, so you can hug the wall and recharge and not miss a beat.

Phone was at 98% at 1:00am and then 96% at 8:30 when I woke back up. All sync is on. No greenify or anything like that. I think standby drain is just fine.

iOS does too. Here's a screenshot from my iPad. I was getting all notifications on time and did everything on it except game.

"Stand by 22 DAYS"..., hilarious. Apple drollery..

If I was a hardcore user, (which I'm not,) all that would concern me is whether my phone could last a day after a few years of use.
As a light user, its nice that my battery can go days but that's what it really is, a nicety.

Dunno about OP but my IP6 always had at least 8-10% battery drain overnight, and I never even had Facebook on it (just Messenger). OP3 is at 3-6% most of times, depending on how many times it got woken up due to notifications.

My battery life is just perfect.
Beta 8 Nougat.
Beta 9 is even better.

-----------------------------------------------------------------------------
Due to insufficient optimization of the Kernel
within OxygenOS, battery discharges much faster.
OnePlus need to improve the optimization
related to the battery discharge in everyday use of the phone.
-----------------------------------------------------------------------------
Well described here,
one of the important reasons:
Stock OnePlus configuration forces display-related processes to use the Gold cluster(formerly known as big cores) exclusively.
This configuration brings a huge power regression since it makes every frame dispatch to wake up and use Gold cores.
This kernel resets this profile to use the configuration Google recommends, which is to use the Silver cluster(formerly known as LITTLE cores)
exclusively instead. No performance penalty was noticed with this change while massively improving battery life.

I have to power off the phone every night. Otherwise the battery consumption becomes massive. Kernel time skyrockets.

OnePlus 7 Pro. Official stock ROM. No root, no TWRP. Bootloader locked.
Powering off every night I can achieve 8 hours of screen usage, from 100% to 0%. If I don't do that, the phone lasts 6 hours at most. Kernel wakelocks start to consume much time, and it's not related to a particular app. I have attached two screenshots of Battery Historian. One with moderated consumption and the other with kernel wakelocks going through the roof.

More like check your kernel. Also, those are horrible drains, 13% per hour screen on and 1.5% screen off. Stock kernel is very poor for battery life on the 7pro. If anyone here is using stock firmware+kernel with no root or no magisk modifications, do a bug report to Oneplus on their site. With how poor the 7pro's battery life is, not enough people actually report it to oneplus themselves. Yknow, the people that can fix it for good.
On my device, OOS 10.3.2, Arter r54, EXT4, I average between 6 to 8 hours of SOT, and my idle drain is sub 1% - I could let it sit idle for weeks on end and still have battery life left over. I don't drain to zero, though - I'm usually plugging it in around 10-15% at the end of the day with moderate-heavy use. Good battery life can be achieved, but the fact you have to root your phone, debloat, and use a custom kernel to achieve it is awful.
I use 10.3.2 because 10.3.3 had much higher drain, as did the latest Arter. I use EXT4 mostly because I forgot to format to f2fs before setting up my phone, though truth be told I don't notice it at all.

Good battery life is subjective. I get 2 days out of a single charge which is more than enough.
My idle drain was sub 1% but has risen since I've installed more apps - and I'm also using the 'optimised charging' feature in OB16.

My GF gets "good battery life" out of her oneplus 8 - easily 2 days out of a full charge, but she hardly uses it during the day, so it idles more often than not, while my phone gets used quite often throughout the day.
When I mention poor battery life, I'm talking about Screen On Time while doing everyday tasks such as news, browsing reddit, texting. I don't play games, netflix, etc. Only the occasional video. Obviously SOT would be lower if you're playing Fortnite or some **** all day. But that's within reason. On the stock kernel, on tbe latest stable or OB, battery life is very poor for most people that actively use there phones. Something is draining the battery more than it should, as the same everyday tasks I mention barely get me 5 hours of SOT, whereas on my setup, I can get close to 9 hours some days.

0.59%/hr with screen off.
10.12%/hr with screen on.
I have all apps frozen with SuperFreeze. So no rogue app consumption. Just bad kernel optimization. Kernel wakelocks are not used by apps.
Battery Historian shows that PowerManagerService.Display and PowerManager.SuspendLockout are the culprits of kernel wakelock abuse.
Kernel wakelocks go from 27h to 319h. Meanwhile userspace wakelocks remain at around 20-25 minutes.

Question High battery usage? Even when I'm sleeping?

The device is new, has only 2 weeks of use and I've updated it to MiUi 12.5.6 (RKLEUXM). My use is very moderate, some videos, social network just for conversations and only wi-fi connection. After the update, I noticed high battery usage even when I'm sleeping with all connections turned off. Obviously there is some battery thief, but it only appears in the graph as "smartphone services", this is not normal. Any idea?
I can even feel the phone a little warm around the cameras when I'm using it for basic stuff.

Try battery guru's app...

It's seem a 12.5 MIUI problem for all Xiaomi note 10 series

Something(s) are running in the background.
Try putting into Safe mode at night to rule out 3rd party apps.
Track down the culprits and deal with each on a case by case basis.

I have this device since August 27th, after setting it up, I started optimizing it, restricted background use for a lot of apps, well, everything that could be disabled or restricted, I only gave free pass to apps I consider important, but, the reults were really bad, 17% of overnight drain! Long story short, the optimization must be done very carefully, trying to stop all kind of things might prove negative, by trial and error, I now get a good battery life, now it barely consumes 1% in 8-9 hrs idling at night, aod off, wifi on, gps on, so, try to optimize your device carefully

Hi,
Did you single out what was the culrpit. I have disabled every non essential app, tried this solution: https://forum.xda-developers.com/t/improving-battery-life-on-miui-12.4139913/
But nothing helps. It only shows that android system is drawing power.
I will be glad if you could point what you made to fix your phone

If there is any Firewall that can log with the newer "secure" OS's you can use that to help pinpoint the rogue apk(s).
With Pie I use Karma Firewall but it's logging feature doesn't starting with 10.

After doing everything I could think of, the AOD seems to be the culprit, even thoug I really like it, when disabling it, overnight battery consumption lowered to 1% in a 7 hrs period

Thank you for the fast reply. I already had it disabled, but with no positive result.
Thank you, nonetheless.

Is tap on an option?

No, to achieve this low bat comsuption, I disabled miui optimizations, then, the option for aod is on or off, no more settings, I really like the aod, but the drain while idling drives me nuts... I painfully miss my galaxy note 10+.....

Meh, I hear that. It's to the point I got a second new 10+ while they're still available. They are the last of the stock devices running on Q.
I won't touch 11 or 12. Funny thing is it doesn't run like an outdated dinosaur.
Been a real bad year for Android...

Question Asus zenfone 8 , I purchased a new Asus zenfone 8 dual SIM 2weeks ago . But the battery life is just shocking. Had anyone have any thoughts on this ?

Hi all
Just wondering if anyone who has an Asus zenfone 8 are having trouble with the battery life ?
Thank you

I'm not sure about everyone. I heard from some people on stock about 6-7 hours SoT, but i don't know how. 5-6 sound much real)

5-6 sounds about right . That's very disappointing considering it's a 4000amh battery . I would have expected slot more hours.

I find the battery life ok but in need of some tweaks (hopefully) on AOD, 2t2w, wakelocks, cpu governors and so on.
Hopefuly they'll put the effort into it.
In my usage, i shut off the 2nd sim when i don't need it, aod, 2t2w/fingerprint is on (w/out the aod icon), reception set on 3g w/ occasional 4g, 120hz (not that much of an impact) but i restrict some of the apps that pool lots of resources and (with a few exceptions) i have most of the battery optimizations on (adaptive bat, managed auto-start aps, bg app mgmt, w/ bat draining apps off.
On an average day outdoors, spotify streams on very high most of the time to BT (aptx hd), some occasional pics/videos, plenty of instagram, some browsing and some youtube. I usually go to sleep w/ 20-30% left. Charging is done w/ shed charging and ultra steady charging during sched charging.
It is my opinion that the screen on very high brightness just eats through battery (I mostly avoid extended usage in direct sunlight).
While excluding the 120hz refresh rate, second battery hogs after the screen would be the 2t2w, aod and the general standby opptimizations.
I hope they'll address some of these but otherwise I pretty much love the tiny guy - there had to be a comproomise for the specs and pricepoint.

I think 5-6hrs with moderate usage is alright
First of all it has an 888 and flagship socs in general are known to have an higher battery consumption plus the higher refresh rate (and depends if you use 5g all the time or if you get a better reception in your area and other usage)
You can optimise some stuff in Asus autostart manager,disable aod (which consumes quite a bit of battery) and some other stuff and get slightly better battery life though
But Asus might optimise battery further with otas though

I got a root. After that, I changed the minimum frequencies of the processor (they are high in the drain, no matter what mode we choose). Chosen by a conservative governor. Removed all Google software. I set the refresh rate to 60 Hz. Disabled AOD. Sim one is 3g, the other is 2g. But I still get the same 5-6 hours. I have a suspicion that the reason for the fast discharge is the radio module.

By the way, what SAR level ZF8 has?
I have good signal 4G and 3G where my previous Note20 Ultra (865+) was often switching to 2G.

SAR value (head): 1,412 W/kg, SAR value (body): 1,582 W/kg (source)
I've attached the official SAR test report of the Zenfone 8, if anybody's interested.

Had mine a full day and the battery is appalling! Come from a p30 with bigger screen, smaller battery and less efficient soc and the ZenFone is draining about 40% faster. Came on here to ask the exact same question!!

Its strange, ZF8 has 4000 mah battery and battery is pretty poor. Seems asus lags behind in optimizing their software

Has there been any software update from Asus that improves the battery life? I've been reading that the battery is a big issue. I'm split between getting this phone or the Pixel 5. I'm currently using a s21U and have been using big screen phones the last few users but I'm ready to switch to a more compact phone, it's rare to find one nowadays. The market has more demand for big screen phones nowadays unfortunately and the current compact Android phone choices are very limited...

So, having used a few days now it has suddenly got much better. I'm off charge since 7am and am writing at 4pm and I'm at 80%. Not massive usage - 1 hour screen time with a little Pokémon go in between which seems pretty decent to me. I've disabled 5g, have screen on auto refresh rate and running latest firmware. I do wonder if low signal strength causes disproportionate power drain, the office saw me down to 30% by mid day work virtually no usage at all.

So I have Zenfone 8 since June and battery life is OK, I can get through a day. Saying that I am a pretty heavy user as I had to charge my pixel 3 twice in a day, while now when my father is using it, battery lasts for 2 days with 4-5h screen on time.
Here is my accubattery estimates. They have gone from 6h 10min to 6h 48m in the last week, so maybe the adaptive battery is affecting this.

My personal record, after two weeks of using this
phone! Honestly, I'm not happy. I was expecting more, when it comes to battery life.

Everything the same except AOD (only for night 8 hours) and auto-sync. Maybe auto-sync is the reason? It's setting in Accounts or some different auto-sync?

Thanks for your reply! Really appreciate it! Do you use two sim cards?

@dron39 just in accounts
@Harthouse no i use only one sim card
