Battery OS 6.1

Since the new update 6.1 the battery life on my Ipad is ridiculous. Lasting only two to three hours. Along with this it only runs on 3G for the most part. If I reboot it it will connect to LTE but then after a few minutes it drops back to 3G.

I have done a reset, a master reset and the issue still exists. Charging it a kip takes forever.
