Just wanted to comment that today for some reason, Google Play Services cannibalized my battery. I do have the new launcher installed if that matters. Anyway, I am going to restart the phone and give it another go tomorrow. It's currently sitting at 11h 46min on battery with 14% remaining (and I plugged it into my car charger for 1 hour!). Normally I get about 1 - 2 days. Google Play services usage is at 61%. Never had this happen before. Anyone else experience this?
