10hrs doing what tasks? My 1520 lasts more that 24hrs using the web a lot. Not so much for calls as people call me in my office landline all the time.I've noticed a huge improvement with Windows Phone 8.1 installed on it. I used to get 4-5 hours with the phones battery. Now I'm getting around 10 hours. Now I just have to pull the back cover off the old 521 and ship the rest of it back to T-Mobile for recycling. I'm keeping the battery, back cover, microUSB cable and power chord as backups for this one.
I just joined their forum and also have it setup in FeedDemon on my desktop pc. Now I just have to add it to FeedDemon on my laptop. I'll do that a little bit later tonight. I have a few errands I have to do first.
badrobot: Could you post a link for the Voucher app. I did a search in the store on my phone and didn't come up with anything with just Voucher as the name. I got a bunch of results, just none named Voucher. My phone didn't come with a $25.00 voucher. Here's a link to mine. http://www.walmart.com/ip/Walmart-Family-Mobile-Nokia-Lumia-521-Prepaid-Cell-Phone/34443770
