Ever since 2.1, when I check battery usage, the application Maps shows up as the #1 user even though I'm not even using Maps. Just unplugged, and the reading is Maps 34% Display 21% Wi-Fi 17% System 11% and on I have not gone into the Map application, I checked the running applications and it doesn't show up. Anybody know why it says it's using so much battery power? And on a possibly related issue, 2.1 Maps performance is AWFUL. It doesn't update very quickly, various symbology elements blink, it doesn't always show the blue triangle when I'm at 'my location.' Anybody else not liking the Map since the OTA 2.1?
