Lots of battery drain while in standby mode

[mattvail692]

I have noticed that this phone the Motorola moto e4 has a really bad battery drain and it looks like that FMRadioService might be the problem I am not for sure but I would like to ask other people what they are getting so we can figure this out

I have the FM radio disabled and don't really have many battery issues. I've been on my phone since I took it off the charger three hours ago, overclocked cpu on performance mode, and brightness all the way up and this is what I'm at.

I did some more digging because my Android system is always high i downloaded gsam battery monitor and found out that the kernel is keeping the phone awake when it's supposed to go to a deep sleep

I'm not talking about the fm radio I'm talking about the fm radio service it seemed to have been using battery for no reason

Ah I see, yeah my battery drain isn't really that bad.

Well I have been digging around more for the past few days and found out the kernel has been keeping my phone awake and not letting it go into deep sleep and I am not sure why

I have noticed something using an insane amount of ram all the sudden.

I have noticed something using an insane amount of rom all the sudden.

I am using stock rom and I am getting the same ram usage as you and I don't really have anything downloaded

Well it used to be at like 600mb steady and all the sudden it's 1.1-1.3gb constant

Mine runs about 1.1 gigs most of the time and sometimes it gets lower but I found out a bunch of system apps have been sitting their for hours doing things in the background and not letting it deep sleep and I can't do anything cause they are system apps

I ended up doing a factory wipe of my phone to test some things, my ram usage is back to normal now.

Hi mattvail692, could you find out the source of the battery drain? I just bought a Moto E4, and I find I can hardly last 1/2 a day. It is burning energy at the rate of 18% per hour.

I use mine all day and usually get a day and a half usage on one charge.
I don't use Facebook or any of that crap, and have disabled most of that crapware on mine.

Thanks madbat99. In Settings-> Battery, I find that the main culprit (48%) is Screen. I wonder what the reason can be, since most of the time screen is switched off.

That means your phone has recorded the screen taking up the most. If your not using the screen much, it could be that your phone is not recording the record of the real reason. Hard to diagnose on a non rooted device. You can try greenify (it has some non root functions). From the playstore. But it's hard to say if it will help until you try it

My current battery. With alot of use so far.

Sitting overnight, no drain while idle.

My idle drain averages 0.6%/hr on stock with all radios on, location services on, full push mail (50+ messages/day) and active display enabled. Device sleeps like a baby yet remains fully functional and engaged with the outside world. Can get several days of light use on a single charge. XT1768 unlocked, rooted (Magisk) with no social media apps (prefer lite alternatives). Living under a rock has it's advantages.
