Any android system drain solutions?

[maduro78]

Like many I've been suffering through this issue since I bought the phone when it first came out. Its murdering my battery life. Highest culprit if battery drain, even more than the screen. I've tried uninstalling Google services erasing data and cache then updating reboot. Tried keep phone on battery saver location , that worked for half a cycle then back to draining. Tried using different Google downloads but kept crashing. I'm not gonna bother calling verizon because as usual not matter how many calls they get about an issue they act like each call their hearing it for the first time. Any solutions about to sell this phone and get the nexus 6p
