Battery Life droped since this week

[Gentei]

Soooo....

I bought the Xperia Z2 in March, I got the phone, since I got the phone I allways had Stamina Mode on.

My Battery Life was allways excellent, I had like between 4-6 hours screentime and I allways could do 3 days with one charge.

(Do note that my 4G isn't allways on offcourse and i'm a medium phone user because i have a tablet at home)

However since this week my battery is empty after a day, when I look at what's getting my battery down it says "Mobile Stand-By"

This morning it was 33% I never had a high percentage like that for this.

Apparantly Mobile Stand-by is the thing that keeps your operator signal on your phone.

I got the new system update like 2 weeks ago but don't think that's the problem since the phone marched perfectly after the update and started to behave differently this week.

Anyone got a fix for this or?

Check if the same drainage occurs in safe mode:

Sadly doesn't help battery usage still the same.

You should perform a software repair:

Mine has the same issue after the update, I've downloaded an app "Gsambattery" and checked, found out it's caused by "Google service", used the app to disabled the service and problem solved.

Will i loose my data if I do the software repair? Is it the same as a factory reset??

Just noticed the following, when my Xperia is charging the stand-by goes down to like 2%

When i'm not charging the phone it goes up....?? **bleep**?

You will lose data if you try a software repair.It is recommended to backup your data before.
