Battery Problem to FlyMe 4.5.7A

Hey guys,
I’m on MX4
I’ve Flyme 4.5.7A and I have very big batterie problems.
Sometimes my phone switches off when it is at 40% and just after when I switches on it is at 1%…
I think this is the OS but I’m the only one with this problem and my phone is New.
If you Know why or how repair this problem, thanks you.
( sorry for my bad english)
