It's all about the battery...

[Derpling]

I would like to say that i hope to make this thread a sticky, and that we as community, can help each other to eliminate the problem with standby drain or any battery related issue.

I would like to open with a recent issue related to Pie, rouge apps, which results in too much battery drain on idle and overnight.

I recently disabled powergenie to maximize performance of device and make sure that my apps won't auto dim(i'll post the commands here, so you won't have to search it):

pm disable-user --user 0 com.huawei.powergenie
pm uninstall --user 0 com.huawei.powergenie

I've been monitoring the battery life ever since, and noticed at first a faster drain on idle, that's because i had some rogue dating apps that i didn't think drain too much(PowerGenie might have prevented them from over draining, even though they ran in the background).

Which brings me to the next conclusion- On android PIE, media apps might drain more power than usual, as it wasn't the case with Oreo.

Since i use various dating apps like Tinder,Grindr,OkCupid, it all might contributed to that fact, mainly tinder which was draining battery even in silent operation.

Some here are some advices: If u use dating apps, at least tinder, make sure it's not running in the background.
Instagram is also a battery sucker, facebook app is the biggest sucker, u might use facebook and messenger light.

When you go to sleep, make sure that u have no active media apps in the background, as they'll try to connect to the net even if you have turned it off(Using Airplane mode kinda defeats the purpose of low idle drain), make sure to turn off all unneeded services such as Bluetooth, Wifi, Mobile Data, Location.

I'll update it, the more i'll find, i'll post some of my recent battery life(was using phone whole night, so it didn't overdrain in the night or idle time).

Powergenie specifically kills app wakelocks that are running too long if they aren't white listed so it's not surprising that some "rogue apps" are causing power drain after you disabled Powergenie since stopping rogue apps from causing power drain is the purpose of Powergenie in the first place.

I'm assuming you disabled Powergenie so you would receive more timely notifications but you probably ended up killing a fly with a bazooka.

There are less aggressive methods that generally fix that problem like removing important apps from Huawei's battery optomization and changing the app's notification priority to the highest available.

Unless your phone is rooted it's impossible for you to block any wakelocks yourself and closing the apps you see open in the display window doesn't stop them from running in the background--it just frees memory.

You can manually stop apps running from the settings/applications menu but they can be restarted by another app or by a system process.

I wish you luck but with Powergenie disabled you are going to end up with additional idle battery drain.

Not sure there I've had this removed for almost 2 weeks and I have quite a vast improvement in the battery performance, also I was having background colour issues with XDA, huawei video and YouTube which has since stopped. Apps open a lot faster and even when I opened Google photos There was a pause in loading photos which has since gone.

That's why it's in testing phase, i get notification and no force close apps. removed hauwei launcher and now toying with powergenie.

I might bring it back and see how it fares on vs it's off, when it's off, you gotta be more aware of wakelocks as you said.

I also uninstalled Powergenie 3 weeks ago. Don't really notice a difference with the battery time. But I'm happy my screen no longers dims brightness within certain apps.

I remember somewhere you said you could still see your battery software stats, despite uninstalling Powergenie? You had installed GSam battery monitor if I'm right? Then do you need to give that app permissions via ADB? Otherwise you won't be able to see the app usage right? After only installing GSam battery monitor I don't see the app usage yet. Also do you have the free or pro version? And doesn't GSam battery itself consume battery?

The stats in battery are gone, but I have Gsam battery Pro, it seems to not use much battery at all, but then I am relying on Gsam to tell me about its own product, but it has the stats pretty reasonable.

Don't understand what the top numbers are about but tells me I'm getting average of 9.20 screen on time, and 10.10 hrs max

Oke. I've installed the app but can't see the software usage yet. Do I need to grant GSam battery monitor acces via adb before I can see my software usage?

Yes, it should prompt you the instructions when you start it.

Seeing an improvement in battery service likely depends on what apps you actually have installed. Apps that were referred to in a separate post as "rogue apps" have wakelocks that will prevent the phone from going to sleep and cause constant battery drain. They are coded either accidentally or intentionally so they will not be affected by standard power saving measures coded into stock Android.

Social media and dating apps are the most likely to do this on purpose so users always receive notifications immediately rather than when Google Play Services does a background sync. These types of user installed apps don't have the elevated system priveledges of something like an sms app so the only way to make them provide notifications immediately is to keep the apps awake in the background which drains battery.

I'm surprised you would see improved battery life with PowerGenie disabled but apparently PowerGenie is using more power blocking wakelocks than the apps creating the wakelocks use when left alone.

I haven't experienced any of the problems that you say disabling PowerGenie fixed on your handset but there are slightly different versions of the OS depending on where and how you got your phone. Some have carrier specific apps. Some have the Google Trust Agent and standard Google Smart Lock options. Some have the Huawei Trust Agent instead and only have a smart lock option for Bluetooth devices. Some have the standard Google Feed as an option on the stock launcher and others have a Huawei created screen instead. Some features are different or missing altogether depending on what region you select for the phone. Some stock Huawei stock apps don't work at all in certain regions. There are a whole lot of variables involved so everybody isn't going to have the same results that you had when disabling PowerGenie.

There's also the difference between the LG and BOE displays. I had phones with both and kept the handset with the LG display because it was brighter, had much richer colors and noticably faster pixel response.

I did notice an issue with brightness dimming while certain apps were running but only on the handset with the BOE display.

Indeed, I put my dating and social media apps on auto manage and brought powergenie back for now.

Results vary between different configurations, but social media apps needs to be kept eye on, in case you decide to doable powergenie

None of this really is relevant to the fact that I was using the phone for 8 weeks with power genie, then soon as I have removed it I have seen a dramatic improvement. The results speak for themselves.

Except the thread OP who followed your advice is now apparently experiencing signifigantly more battery drain with PowerGenie disabled (which is the opposite of your experience) and the fact that I haven't seen any of the problems disabling PowerGenie fixed for you.

Still irrelevant, since I have better performance and quality improvement. So you stating that it's not possible doesn't change the fact that it is.

Since I updated to .187 I have a strange issue.

I booted into recovery cleared the cache, fully charge the battery at 100% I get 11minutes before dropping to 99%

If I Go to apps and manually clear the cache 1 by 1 fully charge I get 36 minutes before dropping to 99%

This is with or without powergenie. Which is currently disabled.

Very strange.

 

[Darkat70]

Why is it if I have uninstalled Power Genie is it possible to still be a running service.

Developer options/running service

Yes, also running on mine even after disabling it.

Just stopped it now. Let's see the results. In any case, pretty happy with the battery so far. Also phone is snappier now.

 

[lil_kujo]

i have tried both with and with out for weeks at a time same usage pattern same network same location, and settings and the only difference i notice is that on idle with out powergenie the phone discharges faster with powergenie enable it stays for a longer time with out losing juice in terms of SOT and usage it was basically the same with it on or off. At least for me.

I've got a problem with the removal of Powergenie since Emui 9.1

On Emui 9.0 I had no problems whatsoever. But since 9.1.0.300 my battery drains very quick. I even tried factory resetting a few times, without backup and I don't have much apps installed, the same apps as I had on 9.0... Also the battery charges slower, because the phone gets hotter. I checked for draining apps with GSam battery monitor, but all apps behave normal.

Only when I put Powergenie back the problems are gone...

I had this problem first on 9.1.0.300, then 9.1.0.310 and now still on 9.1.0.320.

I really want a solution for this problem as I don't want to keep Powergenie installed. With Powergenie installed my screen dims in bright apps. So when I open an app like Whatsapp, Chrome, GMail, or even the calender or notes app, the screen gets dimmer. When you close the app, the screen gets brighter again. This is so terrible annoying and I don't like this behaviour at all.
As far as I know there is no other solution for this problem, except uninstalling Powergenie.... Before I found the Powergenie solution I was really thinking about returning or selling this phone, just because of the dimming issue. But now there is a new problem

Can anyone help me with this problem? Does anyone else have this same issue? Right now I'm even thinking about buying another phone... But maybe Android 10 / Emui 10 will fix the problem?

I don't remember reading about a similar problem...so are you sure it's not an app or something else you uninstalled? I have none of these problems (and I whacked Power Genie 3 months ago, along with 3-4 other Huawei apps) - certainly I didn't expect charging to be affected or that the battery drains actually faster.
The fact that factory default does not have a positive effect is alarming - remind me, does that also restore the system apps you uninstalled using adb? I thought it does...

Running 9.1.0.325 on LYA-L0C.

I even had Powergenie uninstalled since around March I think. Never had a problem with it untill Emui 9.1 came.
I have not installed any new app. It surely is strange that a factory reset doesn't help. But when I enable Powergenie again, the battery behaves normally again. But then I have that horrible screen dimming back. :crying:
