Symptoms:
- Your phone occasionally gets very hot, just below the camera
- The battery drains with about 20% an hour, so your phone is dead in about 4 hours
Solutions:
None for the moment. I sent my phone back for repair, no solution. The only consolation: you are not alone: see Nokia Support Discussions
Workaround:
I “solved” this by limiting the highest connection speed for the Mobile network to 2G. I can easily use my phone with one battery charge for two days now, with wifi, bluetooth and location services enabled. OK, surfing is a bit slower.
I sincerely hope that the WP8 “Amber” update is going to solve the issue.
