I currently have a OnePlus One, rooted and running CM12.0. This phone has excellent battery life, and is very fast.

But I bought a Nexus 6 for my Wife her birthday last month, and rooted it running Chromo ROM, and the phone is really nice too, and I like the larger size, and really like the AMOLED screen much batter, and speakers too, over my OPO. My Wife gives two craps which phone she uses, and she actually would prefer a little smaller device. So I can swap phones with her, and she'd be happy.

Question is, I haven't used her Nexus 6 for a full day ever, I just tinker around with it for an hour or two here and there. But how does it hold up for a full days use ? I know the OPO is known as one of the top battery Android phones out there, and I read the Nexus 6 is not that great on battery life ? ( My wife comes home with 50% to 60% still left on her phone after a full days work, but she barely touches it, maybe 2.5h - 3h On Screen time per day )

So has anyone here had the OnePlus One, and switched to the Nexus 6 ? Opinions ?

Thank you
