C5 Ultra Battery Issue

[Srichal]

Hi, bought this phone last week in India.. The battery drains like anything while using wifi in stamina mode itself... Not sure whether this is an issue with Android 5.0

You should reinstall the latest update with Sony PC Companion.

I've the same problem
And I have done what you many times and the battery still drying too fast and takes too much time to get full charge again

Just try to turned your Xperia on into Airplane mode while charging. Also disable you internet connection (WiFi). It should works just fine for me.
