Using Power when switched off
recently picked up a legend and having some issues with the power usage. I expected it to use quite a bit of power but when I power down over night the battery goes from around 75% to 11%. How can this be when I've switched the phone off? It didn't do this for the first few nights I had it. Is it something I've done? Are there any decent apps hat will prolong battery life?
Any help would be appreciated.
