Battery consumption problem

[koutsi]

Hello there. I have my Z1 two years now, and I am getting extremely low on screen time. No matter if i browse the internet, or watch videos, about 10% dies in about 15 minutes, 2 hours of pokemon go dries the battery, and stamina mode doesn't seem to have any effect. I thought of changing the battery, but I am not sure if this is caused due to bad battery or hardware malfunction, and i am outvof warranty so i dont wanna just waste my money. I would just buy a new one, but i am going to the army, so it gonna have to wait. Any ideas? Thank you

PoGo will drain the battery like crazy since you are using data/wifi, gps, etc, the battery might be old and can't retain charge as it once did, perhaps a new battery will solve this issue.

A friend of mine with a Z3 has way lower consumption on Pokemon Go

There are myriad reasons, I get better battery life playing PoGo with my Xperia X than with a Xperia Z5.
