It's 4:52 and I'm about to leave and I have 32% remaining and it says I have 3 hours 5 minutes, but I don't believe it. It drained 68% in a matter of 3.5 hours. Not looking good.
I used my device for casual web browsing and after 2 hours I was at 50% battery on W10.
Between crappy battery life, crappy OneNote and right clicking bug I'm seriously annoyed at my SP3. The *only* redeeming quality it still has going for it IMO is that it has a full desktop web browser.
But even then, somehow many popular websites (like messenger.com) don't even work properly in Edge, and Chrome is awful.
