I upgraded to WM5 for three days. After my X50mid slowed to a crawl I just couldn't take it anymore, not to mention the horrible bluetooth stack; So, I decided to roll back to WM2003.
At first I was very please all my previous info was still there, X50 was back up to normal operating speed, everything seemed fine until today when I noticed a problem after charging to 100%. If I turn on WiFi when my battery is at 100%, I can literally watch my battery level decrease very rapidly. I'm talking about major decrease! 1% every three seconds

. It finally levels off at about 86% What can be causing this?
PS: I have A05
