LGG4 Battery Saving Tips?

I know im not the first person to ask this but if you guys have any battery saving tips it would be appreciated.

LG-G4 (VS986) and very odd camera-related crash

I have an LG-G4 (VS986 - Verizon), rooted (13b). On three occasions over the past week, the phone has hard-crashed (totally powered off immediately and unexpectedly, and would NOT power up, even after a battery pull). In each case, the only way to bring it back to life was to plug it into a charger, which booted it up when the power button was held - but in every case the battery was at least 80% charged at the time of the crash (and I tried two different batteries), so it wasn't a power issue. It only happened when using the camera (actually taking pictures, not browsing through the gallery). It doesn't occur every time (I shot about 15 pictures this morning, and it didn't reproduce the crash).

I also have noticed that the pictures do not flip vertically/horizontally during viewing (usually in QuickPic but also in Gallery) but Advanced Tools says the accelerometer, etc. are working fine. Tis is also recent.

Anyone else seen this?
Thanks in advance...!

LGG4 h815 freezing and restarting with CM13 and Genisys rom 4.2

So my g4 started randomly restarting itself, so i decided to do a factory reset.
In my haste, i wiped all data from the phone including the OS. Since then i have tried flashing genisys rom 4.2 via twrp.
It installs okay, but after inital set up, it either freezes and becomes unresponsive, or starts ressting itself over and over.

Thinking it was the rom i have since tried flashing CM13, but again, it either freezes and becomes unresponsive after install on the homescreen or is resetting itself.
I am now stuck for ideas on how to resolve this, so any help and advice on solving this would be greatly appreciated :)
