I've had my 920 with ATT for 2.5 years now and it's been a great phone. It's had a few issues but overall I love the phone and haven't really even felt the need to upgrade. Well 2.5 years does take a toll on the battery no matter what and I'm lucky to get through the day without charging it. I'm off contract and will stay with ATT and have been looking at the 830. It has pretty much everything I want especially wireless charging built in. The 1520 is too big so the 830 looks just right to me. I know it's more of a sidegrade than an upgrade but I don't know how much longer I can deal with my 920's battery. I know as soon as I get the 830 MS will release info of their new "flagship" phone (all these "budget" phones are annoying) and I'll regret the 830. Is the 830 up to par to keep up with future updates from MS such as WP10 and other software updates? I know it won't have the "Hey Cortana" feature due to the processor, but I don't have that feature now so I wouldn't miss it. I don't want to be in the dark completely though if MS releases a bunch of cool features that the 830 won't support. With Amazon offering the 830 with the FitBit package for $0.01 it's making it really hard to turn it down right now. Is it worth renewing a contract for or should I wait for the possibility of a new flagship?
