Nokia Lumia 800 battery problems surface

The Nokia Lumia 800 promises to bring you the “amazing everyday,” but many UK users have found the “everyday” part to stand for daily charging. To be perfectly correct - multiple daily charging as the Lumia 800 seems to experience a battery drain issue.
“I had it charged last night and when I got up in the morning it was down to 35% from just sitting there. … I don't use it that much during the day but it seems to go down really fast. I'm currently at 47% and it estimates 1 hour left,” user mkr10001 kicked off the discussion at Nokia Support a couple of days ago.
“I just had similar problem with my Lumia 800... it was on full charge before i went out....made a couple of calls, took a couple of pics. Wifi was swictched off....and after 1 hour, the phone went dead!!! Couldn't even switch it back on after putting it back on charge again....completely dead!!! Phone is running latest OS - 4470....which was meant to fix battery issues [sic]” commenter RajC said.
