High Cpu Usage. Battery Drain on Standby - Lenovo P2 Questions & Answers

I recently purchased a P2. Every thing's good. Battery life is also better than most of the phones. But, one thing that I noticed is that Cpu usage is high in idle state too. I did a factory reset. But, the problem persists. I usually get around 8hrs SOT. I think that's lower than most P2's.
Is there a way to solve this? My bootloader is not yet unlocked. Have to wait 12 more days.
Thanks.

Wait 12 more days, unlock the bootloader and flash the DrainFix.zip that can be found in Lineage and RR threads.

Are you still on Marshmallow ? There was a bug that caused the cpu to stay at 1689mhz on some phones .
And Drainfix wont make any difference . It changes the governor from performance to interactive , but your already on the interactive governor .

I am now on nougat. But same problem. Already performed factory reset a couple of times. Cpu doesn't stay on 1689mhz. Now it fluctuates. But, still heavy usage from CPU.
Battery drains by 7-8% overnight.

I already installed Nougat, but the phone is sleeping as dead. Charged it to 95% last night, put it on airplain mode and today in the morning after 9h to battery is still 95%.

The android battery stats show that CPU is awake all time, but BetterBatteryStats shows that everything is fine.

Mine is dropping in Flight mode too . Its probably the system tuning itself up while its idle , it should settle down in a few days

I have the same problem
Have you found any solution? I purchased it on 21 April 2017 and currently running it on Naugat.

Here is how it was for me.
I took phone out of the box with MM preinstalled and right after i turned up the screen and connected to my wifi network it asked me to update OS to Nougat 7.0 so i did. The bug that caused CPU stays at 1.69Ghz occures for 100% on Nougat, and you say on MM too ?
Anyways, for me, hard reset solved the problem, at least this one.
But battery drain still takes place. In normal mode 3-4%, in ultra power saving - 5-6% over night (5-7h). This is pretty a lot i would say.
ps: Phone goes into deep sleep mode according to BetterBatStats.

On p2 i get average SOT of around 13hrs

Thanks ill try it once im rooter in 9 days.
So far im very dissapointed with my bateery life. I get 8.5h over 3 days use. It's not really a good result as for such a battery and screen technology.
I counted exactly - 23% of battery went for standby. It's a lot, isnt it ?
Any ideas if its Nougat fault, or bad piece of phone ?

I think u need to drain your battery completely till the phone shuts down then recharge completely while the phone is off then power on and try

How did you install magisk? Did you root using magisk or using phh superuser? Right now I am rooted with phh.. I would like to change to magisk. Please guide or send link to a guide..

Systemless root under Nougat with magisk:
1. Format data partition to ext4.
2. Type in the recovery terminal :
echo "SYSTEMLESS=true" >> /data/.supersu
3. Flash the magisk12.zip
4. Reboot
5. Install Magisk manager
If you have another su like phh, will not work, you need reinstall the original boot image.

Should be around 0.2%/hr...

The only way to know the standby drain is normal or not, try install GSam Battery Monitor app...
As shown above, native stock ROM S233 should drain around 0.2% per hour, which in turn to be 0.2% x 8 hours sleep = 1.6% or 1.6% of 5,100mAh is 81.6mAh energy consumption...
Conclusion:
P2a42 can survive in airplane mode for 20 days on a single charge.

So, i just checked my Gsam, and here is what is says:
0.7%/h drain in standby which is more or less what im losing of battery juice over night. It's stick Nougat form OTA update.
Right now im at 44% and i switched into ultra power saving mode. It says that i have left around 51h. I dont think this is normal. Isnt it really very little time ?
It's just a little over 2 full days @ 44%
Damn...
Should i return this piece to store with complain i got faulty one ?
Can you please switch to ultra power saving mode just for a second and tell me what did it calculate aproximately as time left on battery ?

What do you do to reduce your Tab S power drain?

I have a SM-T800 on CM12.1 that averages a current drain of around 60 mA during deep sleep. I also have a OnePlus One that averages around 9 mA during deep sleep.
I'm using Battery Monitor Widget Pro with the "Android mA" setting to get my readings on the SM-T800.
Obviously, there's quite a difference there. The SM-T800 draws almost 7x as much current while it's doing nothing - no screen on time.
It makes me think that there must be something I can do to reduce the current drain, especially with a rooted device. But, I haven't been able to figure out what.
Has anyone been successful getting their battery drain lower? If "yes", what have you done?
Thanks,.

Did you forget the thread you made 2 weeks ago.
http://forum.xda-developers.com/galaxy-tab-s/help/sm-t800-barry-drain-t3157867
John.
Yeah, @Tinderbox (UK), but since the title was messed up I didn't think folks were looking/responding/searching to the older thread.
I think this is still something we can all benefit from, if someone has figured out a way to get our power consumption down. And if someone does respond back to this thread, other folks will be able to find it when they search now.
I use Euphoria OS and debloat it, that gives me a few weeks of standby if it's just sitting on a shelf. Ensure you delete Trebuchet (replace with Nova/Apex/etc) as it sucks a huge amount of CPU power when idle.
If you can run without GApps you'll maximize the savings.
As i said last time my T800 only used 1-2% in 16hours what ma does that work out too, the battery is 7900mah
7900mah/100 =79/16*2=9.8mah
Every time you install an app, it can make an huge difference, if it stops your tablet from sleeping.
You need to check your wakelocks to see which apps are keeping your tablet from going into deep sleep, auto check for emails, sync, alarms will cause your tablet to come out of deep sleep.
John
Thanks, @Tinderbox (UK).
As a test, I decided to wipe out my current installation, and just load the latest Nvertigo SM-T800 ROM and the very minimal nano Open GApps. I had to load a few minor things beyond that to get functional (KeePass Droid, Opera, MyBackup Pro, Wakelock Detector). I disabled all Google account sync items.
I disabled Trebuchet wake-ups, and set autostart off (Thanks, @fraser.dk)
I'm still seeing about 1% drop every 4-5 hours.
Nothing stood out from Wakelock detector. After 24 hours of the tablet sitting idle, the wakelocks were all less than 30 each.
Are you running a specific ROM or Kernel?
I am on the Stock UK v4.4.2 kitkat rom, I have never flashed though i am rooted.
If you are rooted, try the app in the link below, it link to XDA and you can download a version of cpu spy reloaded, it works great at spotting wakelocks it`s the only wakelock detector i use now.
I am running an Sony App that is supposed to stop all wakelocks, it`s in standby mode, you can whitelist apps if you like, I am not certain if it`s doing anything at the moment, you need root and exposed installed.
http://www.xda-developers.com/optimize-battery-life-with-this-useful-app/
A 1% drop over 5-6 hours is not bad.
John.
So i have an result on the Sony Battery App, I put my Tab S into sleep mode at approx 12:30AM it was at 69% , I woke it up at 6:50pm, it was still on 69% after 17hrs.
Click the link below, to see an screenshot of GSam Battery Monitor.

for me i have downgraded back to stock kitkat 4.4.2, debloated, rooted and xposed installed, and use powernap, i can use the tablet all day and still have between 45% - 60% battery left depends on if i am playing games or not... i have tried so many apps and custom roms in lolipop and none of them have good battery life....
PowerNap which is the Sony app i use, only reduce battery drain in sleep mode, by stopping all wakelocks, it does not reduce the power that games or other high drain app require, so how does you battery last longer, how much power were you loosing overnight when you tablet should have been sleeping it must have been immense.

on kitkat i had no major battery drain, i just like having powernap on my device... on LP like i say even just using the tab battery would drain like 1% every min... just doing typical web use... i have tried everything to get good battery life on LP but nothing works for me at least.. but with KK i have no issues...
A lot of people say they have had no problems with lollipop, but there is an significant number that have reported problems after upgrading, I decided to stick with kitkat and await android m.
1% a minute just browsing that`s bad.

I think I'll try going back to KitKat, and see how things go.
I have been frustrated on how fast the battery drains when doing minimal tasks, like reading an ebook (about 1% drain a minute).

I installed the Canadian stock KK ROM (T800XXU1ANJ6_T800XAC1ANI1_HOME.tar.md5) onto my US SM-T800, and it's boot-looping.
I thought I should be able to load the Canadian version without any problem.
Is there a way to turn the tablet off when it is bootlooping? I don't want the battery to drain while I'm downloading another ROM.
Try this to stop boot loop.

Out of the bootloop now, and setting up KK.
What do you do to prevent OTA updates? I have TWRP installed via the All-in-One Auto Root.
If you are rooted you will not get ota updates, if you are not freeze the updater an tab s owner did that with an app called "package disabler" it works without root but the free version keeps being removed from google play store, the full version is £2 (£1.50) just reduce.

@Tinderbox (UK) WHAT KITKAT ROM YOU ARE USING ????
stock UK kitkat rom v4.4.2, Lollipop has been out for my T800 10.5" for an couple of months, but it is full of bugs, and quite a few people have went back to kitkat.
Kitkat has been solid for me, I ran it for 164 days continually, I never rebooted or shutdown in that whole time, no problem at all.

[FIX] Battery Drain,No Deep sleep, Android os wake-up all time

Tested on Lineage OS14.1, PurefusionNougat, CRDroid (not tried in other ROMs, it may work)
After trying a lot of modifications in two weeks regarding battery drain due to android os wakeup all time and little or no deepsleep, found a simple way to solve the issue.
1. Calibrate your battery according to post #9 (https://forum.xda-developers.com/showthread.php?t=2765663)( (Essential- it will fix almost all errors regarding battery)
2. A simple build.prop tweak wifi.supplicant_scan_interval=200
Add this line to system/buildprop using a root explorer with root permission " wifi.supplicant_scan_interval=200 " and reboot.
Screenshots after applying the mode
I edited the build.prop file via BuildProp Editor in the app store. So does i add that line in the beginning of the file or at the end?
do build.prop edits need a reboot to work ?
But yeah... WiFi has always been an issue on the HTC10 -.-

Battery Caliberation that also worked for me according to this xda post by @bikercr https://forum.xda-developers.com/showthread.php?t=2765663
Thanks to @bikercr
His Post
"This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)
NOTE: Another potential fix for battery/charging abnormalities if this procedure fails (esp. after an OTA update when corrupted files can remain stuck in device cache partition)--clear cache partition using this method: http://forums.androidcentral.com/ver...ted-phone.html"

This fix increase standby time (battery drain and no or little deepsleep due to android os awake all time)
This fix have little impact on SOT. SOT depends on many factors like Screen brightness, Surfing on 3g, 4g or wifi, playing Games, watching videos etc.
A Little Story
I bought this device through OLX and the seller selling it due to poor battery backup and warmer device even in standby. Due to interest in tweaking and modding from my first android device(Samsung spica 256mb RAM!) i bought it (with Android MM). Found the device doesn't enter in to deepsleep and android os is in the top of battery consuming. Two weeks of flashing differnet roms, Kernels, tweaking kernel through Kernel adiutor app, disabling and removing of apps , build prop edits etc. One day i noticed that my device goes to deepsleep almost suddenly after locking. Flashed the device again and do the tweaks one by one to know which tweak give me the result, and found the wifi scanning interval build prop tweak is the reason.
And it runs smoothly almost all time and some time it shows battery drain. So done some more googling and found this post in HTC One (M8) forum https://forum.xda-developers.com/showthread.php?t=2765663)(. It realy helps to completely overcome the Battery drainage issue. Then i tried almost all nougat roms and all of them are giving excellent battery backup.
Now my device have no deepsleep battery drain issue and now trying some bloat removed nougat stock.

i made some screens.,. will upload later
first of all, it was defintly better than last 4-6 weeks...
battery juice goes down from 100-0% not like 100 to 98 to 86 to 80 to 52... u know that % jumping around, reboot between 19 and 23% and so on...
but i have had a screen on time of about max 2 hours and my battery was down after 8~9hours... -10%battery per hour in power saver mode with lowest brightness
heere my results :
6:25 100%
74% after 2h30m with screen on 21 min
45% after 6 hours with 52min screen on
12% after 9 hours with 1h16 screen on
3% after 10h15min with 1h18m screen on
after the 10 hours i have had battery usage:
40% Mobile Network Standby
29% Apps
15% System
6% Phone inactive
it was defintly better than before but i have had also the battery draining... btw im on lees r143 with cleanslate kernel....
i install elementalX Kernel with a bit of uc and deactivate some stuff i dont need i will test it tomorrow and report....
maybe we find a solution together....

40% Mobile network standby is due to low network coverage and network use more battery to establish a good connection.

on my phone , wifi running is always 100% , I think that is "always scanning option enabled", so this option is draining my battery?
or
which I sacrifice doing your method to my phone?

wifi.supplicant_scan_interval=200 if you switch on the wifi always scan mode, then wifi trying to search for available networks all time, if you add these lines to buildprop it pause 200 seconds between scans and it help to reduce battery consumption, drawback - time for find a new wifi hotspot may increase.

new battery and having the same problems before the old one died.

Hi all,
I got a new battery a week ago, because my phone didn't turn on or charged anymore.
But my battery keeps draining. I lose around 25% in idle at night time. And around 3% every 5 minutes when I use it.
I used gsam for a few days now to see iff there are any applications that are causing the drain. So far I can't discover any.
Also when I'm using my phone the side of the power button gets hotter then the rest of my phone. While the battery and cpu both are under 40 C.
I do have android 10 and 2.1 ui from devbase rom with soldier 6.0 clean installed, tried other roms aswell, so maybe I should get back to android pie?
I also started using ex kernel with the standerd underclock option you can choose while flashing this helps a bit.
Hopefully somebody can help me out.
Some gsam data
I have the same. I used different roms and kernels, all the same. I turn on airplane mode for the night. it helps a bit.

Thank you, this reassures me that It's just a coincidence that my battery died, and that the behavior of my phone at the moment doesn't mean it would happen again.

I do notice, that gsam says that that I am using wifi all the time. And it shows that battery usage is high when this happens.
The only thing is that I never use wifi anywhere..

Something drains my battery very quickly

Hello
The problem is that something drains my battery really fast
According to AccuBattery it's 40% per hour (380mA) active drain and screen off 10-18%/h
On BBS everything seems ok, deep sleep is ok
It was the same on stock MM v20p
I'm on latest LineageOS 16 + microG and I just replaced my battery (looks like original and date is from june). I replaced it because I had random reboots when battery was at low level and it also was draining like crazy.
Any ideas what can it be?

Same just started happening to me. Using a powerbear, same rom. Just installed acca and it was working fine. I noticed the past day it's been dying while charging.

Yeah. I just use it for a camera monitor. Looks like wiping cache and dalvik in twrp fixed it.

Question High battery consumption on idle

My phone is usually on idle and not used due to my job. But Im noticing extreme battery consumption even when Im not using it. Never had this issue with other phones. Last night I checked the batter before sleep and it was at 67% at 1 AM, today its 62% at 7 AM so there must be an issue because it should only drain 1 or 2 percents during idle.
In battery settings the top app using the battery is phone idle.
Im on xiaomi.eu 12.5.6 rom but I had the same issue with stop 12.5.3 so I dont think it's because of rom.
I had great battery life with my last phone which was poco x3 nfc with the same settings and apps so it's not because of any third party apps either.
Anyone else experiencing the same problem?
With AOSP ROMs, I even had worst experience when I installed one of the custom kernels because they somehow didn't put the phone into deep doze correctly. But yeah, the idle consumption is quite high - even on stock Kernel.
Currently I use HavocOS and its stock Kernel - and SuperFreeze (from F-Droid store) to freeze most apps right after screen lock. Idle consumption has dropped to 0.1-0.2%/h as a result. I made a thread some days ago regarding this topic... see here.
Thanks. Im gonna try your guide but it's not the most noob friendly guide I've seen
Just Kidding, thanks for your time.
Oh, my thread wasn't meant to be a guide... I did put it in "Question" like you did, but a mod seems to have moved the thread to "General"
My "solution" is only temporary - at least I hope there are still developers out there who value a low idle drain more than fast charging and benchmark numbers...

Sorry for the OT, could it be that the app. is called SuperFreezZ?
Have you noticed any good battery life gains with this app.?
Yeah, sorry, SuperFreezZ: https://f-droid.org/en/packages/superfreeze.tool.android/
For several months I had the problem that from a certain moment, the consumption at idle suddenly increased enormously (from 0.1-0.2 % to 2-3% per hour). Even if I manually forced all apps to stop, In Android's battery info "Android OS" and "Android System" showed up with double-digit percentages. I could only get the phone back to its previous behavior with a restart.
To date, however, it is not clear to me what triggered this. I suspected GCam for a while, then Osmand+, but I couldn't ever confirm that because the problem didn't start whenever I used those programs, just sometimes.
I never found a real solution for this, but SuperFreezZ did.
The best thing I've used for years now is Greenify, its hasn't received an update in more than a year but still works perfectly
Do we need root to use these apps? I remember using greenify before onmy older devices with root but havent used it for a while. Gonna see how much it drops tonight and then try to tweek some things and recheck it tomorrow night.
Weird thing is, I was getting an awesome battery life out of poco x3 nfc, could it be because of the cpu idle? Because that's the only thing that seems different between the 2 devices. (X3 even had an lcd which is supposedly less battery friendly)

Unfortunately, hardly anyone notices this because most users do exactly what the F3 was designed for: Playing games.
I came from a 2.5 years old F1 and it lasts easily longer than the F3 although it has a smaller battery and a LCD screen... The F3 behaves anything but fully developed. These latest high-end SOCs (870, 888) are really powerful, but unfortunately not equally power-efficient. That's the reason why I throttled the CPU and undervolted the GPU. This dropped the active drain from ~8 %/h to <5 %/h on my device and my usecases.

Yeah. I used to underclock the cpu on my old phones but I dont know about undervolting. wouldnt it cause issues? I just used 3c toolbox app to set a lower max clock and a lower min clock for cpu cores. I read somewhere that rooting xiaomi.eu rom breaks some functions so I havent rooted it yet. do you have any info on that?

As long you don't push too hard with undervolting, it works quite well. See attached image (it's not mine, but I have oriented to it).

Konabess doesn't need root, afaik. Extract the boot.img of your ROM and copy it into a folder of your device. Then use Konabess to modify the settings and repack it into a modified boot.img. This file you can flash with TWRP. No guarantee that it works for xiaomi.eu, but it works for AOSP (at least it worked for me).

I'm ont he same rom as you and let me explain my experience.
My battery has been insanely good. Even with heavy usage over a period of 4 hours, which included 1.5hrs of SoT and pandora playing though bluetooth all 4 of those hours with dolby and viper enabled. Was at 100 and dropped down to 94%. So It may be an app or setting that you have installed causing problems and draining battery. The only battery saver addition I have installed is Universal GMS doze. Idle time for me It takes me about 5 hours to drop down 1%.

Well if there is an app that is causing this, it should be shown in the battery settings. But the only thing that is eating up my battery is phone idle. So it might be a service or something. Im out of options right now unless I find a way to root this rom without facing new problems.... Worst thing with miui is that you cant do things like rooting as easy as other roms.
Btw, would you please tell me the settings and xiaomi.eu version you are on? Im on 12.5.6 stable and using 120hz + vivid color scheme and most of my apps are on blcok background activity except my messaging app. And Im losing battery on phone idle not the screen on time!
Ss below.(dropped from 92 to 82 woh only 30mins screen on time doing nothing but checking xda!) And 7hrs of those 9hrs I was asleep and the phone was on airplane mode + gps off!
You could try BBS or similar apps. Maybe it's an app which prevents the phone to go to deep doze (wakelocks).
BTW: MIUI sucks

I switch my screen refresh rate down to 60hz but since your phone is idle it really shouldn't come into play unless you have always on display or turn screen on for notifications.
Rooting this phone is amazingly easy. Takes like 5mins if that. My Mi 9 lite took longer to root then this phone.
As far as an app draining battery, It more then likely not it since you saying phone idle, which in the past people have said if you phone has problems with signal this can drain a battery. For me this has been a major issue. With AT&T service I would loose double the amount of battery over night (I play pandora through out the night when sleeping). Also if you have apps that are heavy internet usage (unsure where you at but things like facebook and messenger drain tons and yet don't register battery drain on most analytics. And since you using a xiaomi.eu rom I know alot of those bg services are disabled or removed.

Yeah thanks for the info. I used to root my devices easily by flashing magisk but it seems they have changed the method, though I found the method on a post on xiaomi.eu website and rooted my device.
Tried to lower cpu frequencies a little and use superfreez app. It seems better now but not as good as what you say...
Gonna play with settings a little bit more and wait for another xiaomi.eu stable update to see if it's a bug on this version.

Someone made a auto script for it, but you will have to reflash rom and factory reset data. You really shouldn't have to change cpu feqs. Also uploading a screenshot of my last 2 hours. I know its only 21min of SoT but also 2 hours off charger but playing pandora as well as some other app usage but still at 100%

Konabess without root won't start, any idea?

Ah, ok... I thought you could load a separate boot.img - my fault, sorry!
Then you've to have root for Konabess...
Just to show what's possible with HavocOS 4.9 and 12.5.6 EEA firmware, see atached screenshot... It's with the stock kernel of HavocOS, but with the modifications I did mention here.
Running for almost 2 days
~8 hrs SOT (2 hrs of which with 120 Hz and 2 hrs of which with 100 % brightness, otherwise 60 Hz and brightness between 25 and 50 %) and still 50 % battery left.
