M2 Dual Charge Drain Problem (%95)

[BlackShadow1]

When i charged to %100, it is draining fast to %95 in half hour. It appears after upgrade KitKat 4.4.4 in a few weeks. Is it need calibrate battery or another way? How can I fix that problem ?

It'll be wise to reinstall the latest update with PCC

It says "already have last update" I tried uninstall a few applications, but still charge is draining fast.

Or you can re-flash FTF using Flashtool.

You should see an option to repair the phone.
