[LG Optimus G Pro] spexwood:
I had no response to your post until this morning when things went sour on my phone again.

On Saturday night, I reverted back to 4.1.2 (e98010p to be exact). I was sick of the E988 ROM being locked to the Chinese area. Specifically, the Quick Remote, which didn't have US cable company set top boxes. I tried replacing the Quick Remote files with the E980 ones, but every time I did so, the remote app would disappear from the app drawer, even though the permissions were set correctly. And this was after a reboot too.

I also had issues with Better Battery Stats getting uninstalled after a reboot when it was set to a system app (which is needed to get accurate data on Kitkat).

So anyway, like I said, I reverted back to Jelly Bean Saturday night. I've NEVER had any issue with Jelly Bean, and the phone was working perfectly all Saturday night and Sunday. That is, until Sunday night (last night) when I began to get the EXACT same wakelocks, heat, and battery drain as I did on Kitkat!! My phone began to suddenly heat up and I lost 50% battery within 2 hours!!!!

Google has pushed out the Google Play Services 5.0.84 update, and people who have been suffering from this kind of high battery drain, such as the Sony Xperia users, are still having issues. I am wondering again if this is the Play Services. I just uninstalled the update and completely disabled Play Services, then rebooted my phone. I'll be going to work soon, so I'll test if this works or not. It wouldn't be an ideal solution since Play Services pretty much runs all the Google stuff on your phone, but it will at least point the fingers at it if the issues disappear after I do this.

If this IS Play Services, I would want to know why the heck Google isn't fixing it! There's not even a way to contact them (AFAIK) to report these kinds of problems.

I have been using Android since 1.6 Donut, and I love the system and the customizability, but this crap is annoying me enough to consider ditching it and getting that new 5.5" iPhone 6 that's coming out soon. And trust me, when I say something like that- me being someone who has refused to own a single Apple product since the first day when the very first iPod came out- I'm saying a lot. This problem doesn't appear to be isolated to just our phone. Xperia and Nexus users are having the same issues. Sony has even pointed their fingers about the battery drain at Google Play Services.

If anyone wants to read more, search:

"Google Play Services 5.0 battery drain"

"Google Play Services 5.0 wakelocks"

"Google Play Services 5.0.84 battery drain"

"Google Play Services 5.0.84 wakelocks"

"Google Play Services 4.4.52 wakelocks"

"Google Play Services 4.4.52 battery drain"

I'll reply back after work today regarding the Play Services disabling.

UPDATE: OK, so It's been 10 hours now and my battery level is at 79%. My screen on time has been 45mins and Android OS is running at 7% (the lowest it's been!).

I noticed something weird today too. When Google Play Services is disabled and auto sync is on, certain apps, like Keep, will post and Error in the status bar when trying to sync. It says something like "And application requires and update. Requested by [APP]."

Well, this was getting annoying, so I turned off auto sync, but I kept getting this error from Maps. I keep location off at all times, so why would Maps be doing something in the background, but failing because Google pLay Services is "no updated," so to speak!? I also have Location Reporting off too.

I also did more research on some of the issues I was having. Android OS is running real high in the battery usage list. The wakelocks I've been having are all "Wlan_Wake" and "Wlan_rx_wake," which are wifi related. In Processes, I get a dhd_dpc process that runs for hours throughout the day (pretty much the same amount of time as Android OS in battery usage). According to further research, dhd_dpc is the wifi driver on the phone.

I decided to look at my router and noticed that its firmware was... 4 years outdated....

I'm updating it now, but I have no idea if this would do anything to help since I still have these issues when I turn off wifi. I also enabled AP Isolation on my router to see if it does anything.

Google Play Services is reenabled and updated back to 5.0.84. Let's see if any of my issues start again.

These problems still occur when I leave my house, but they always seem to start when I'm home. Every single morning, the wakelocks/process issues start as soon as I unplug my phone from the charger. But it's almost like I take the problems with me when I leave the house, and once this happens, they continue until I reboot the phone. Then they eventually start again after an hour or two. So what I'm trying to say is I have no idea if this will do anything....

UPDATE2: OK, it's only been a couple minutes now and my phone is already heating up and hasn't slept this entire time. It's DEFINITELY something Play Services related!
