What is going on??

Megan

I have the iPhone 6S and the iPad mini 2. They updated when the new update came out and ever since things have been off. I’ll just be sitting down and listening/ watching something on YouTube and Siri will come on or the video will randomly pause. I can just slightly move and it will happen. The other day I was walking and tried to listen to music on YouTube while I did, my battery was on 50% and after 2 minutes I moved the video out of the way and my battery was on 10%. There’s been some other things going on and it’s really irritating. Is anyone else experiencing the same thing?
