Battery life

Please, please, P L E A S E, when Apple issues the next iOS update, fix the battery leakage problem that I've suffered from with iOS8.1.3, 8.2 and now 8.3.

I don't want more facilities.

I don't want Beats Musice App

I don't want politically correct Emoji

I just want my battery to last as it used to with iOS8.1.2 and earlier.

I've tried all Apple Supports suggestions including going back to factory settings and re-installing all apps and data.

Apple Diagnostics indicate that there's NOTHING wrong with my battery.

It's iOS that's at fault.

PLEASE fix it!

There are plenty of others wanting the same thing!
