It's the same on mine. Google play services has taken 1.7% and has been running in the background for 16 h 49 m, since last full charge. Google play store 0.9%. I'm guessing Google play store is down to having automatic updates on. So it's running in the background checking.
it needs to run if you use anything to do with google which is pretty much everything. its used 1% from your screenshot. Does that really matter that much?
I have fully checked and trust me it's Google play services and the actual store. Yes I know when we use our phone other stuff are in background but still it's not right. Even iPhones don't have much in background. I love Android for a reason. So user friendly giving so many options. I don't customise my phone apart from put majority apps to sleep. With Google background processors I can't seem to disable things such as play store or Google play services so it seems to me it's definitely the software with Google play and play services
