I've recently bought a brand new Lumia 1020 from Amazon. Simply astonishing phone. Huge improvement over my Lumia 900! The only downside is battery life! I was supposed to get a free camera grip, but I didn't. When I took it out of the box it had like 30% off battery, and I was so excited to explore it so I didn't fully charge it that day. I'm kinda worried because the battery doesn't last a whole day and I've only had it for 3 days! Will 8.1 fix my problems with battery? Should I hard reset before or after? Will that erase things Microsoft points in my account (from the Gift Voucher app)! Thanks
