Few problems using xperia z3

[Hassoun907]

Hi everyone i bought my new xperia z3 since 4 days
First: My battery is reaching 40% with 5 hrs screen time on. I let my phone only to reach 40 to avoid charge cycles
Where is the xperia z3 overrated battery who can last comfortable for 2 days
2:Is it bad to charge my z3 from 40% to 100% (I MEAN.reaching full capacity)
3:my battery really will get better after few days of using
THANK.YOU (WAITING FOR YOUR REPLY)

Greenify will run in the background, it will drain your battery and create other issues.

The battery should be ok wether you charge at 40% or at 90%, here is a useful link
