Doze is suppose to help extend battery life.I'm looking forward to Google Now on Tap, and Doze.
They claim that a Nexus 9 on M vs Lollipop, the M version got twice as much battery, that's a pretty bold claim. What I'm wondering is why they didn't test this on a Nexus 6 with services activated, that's the real test imo. Majority of Android users are phone users, so why did they test it on a tablet that probably didn't even have data service (if I missed that part lmk).
