Strange severe battery drain, never sleeps topic


I've had this phone for nearly a year and despite not being able to do more such as running an AOSP-based ROM, I've been fairly happy with it until recently as I'm barely able to get any battery life out of this phone! I am lucky to get 6 hours!

A few months ago I had an issue with battery life when I decided to try Lollipop (OA8 at the time). I had significant battery drain along with the usual issues that have been reported. So I decided to ODIN back to, at that time, KitKiat NI2. The battery drain followed, despite having completely wiping the phone along with completely downgrading the phone.

I decided, as a last ditch effort, to ODIN all the way back to NCG and allow the OTAs to update the phone, which worked beautifully and give me back the normal 24+ hour battery life I initially started with. Well, after having some sluggishness I did a standard wipe, just wiping the data and cache, leaving system untouched. The horrible battery life has returned!

I have tried on numerous occasions to ODIN back to NCG and OTAs, multiple wipes, run without any 3rd-party apps, no accounts assigned, without any luck whatsoever!

According to Wake Lock Detector the phone is refusing to sleep. What bothers mie is that it'll say an app is causing it, so I delete it. Then another app will take its place as top of the list. Again, I remove it only to find yet another app to the top until Android System is the top.

I currently have a brand new Samsung battery installed which made absolutely no difference. I also have reinstalled my apps, stuck with KitKat NK2, and rooted. Never have I restored any data with Titanium Backup, system or user in any way.

Could there be something hardware-related causing this? Anyone else have this problem? Verizon doesn't seem to want to help me other than giving me the standard scripts. Sadly I can't switch carriers, either. TMO would be my choice but sadly they have no coverage in my area (I tried!)
