I would spend some time looking for some apps that affect your lockscreen. I currently use Paper Shuffle. As well, maybe invest in a new wireless charger
Battery life will probably suck initially. But give it some time and it will get better. I took original back and new one wasn't any better. Took about a month to start getting good life out of second. Might help to use USB charger that came with it until battery is conditioned. Just a theory. And keep an eye on background tasks. If you don't need it operating in background don't let it.
