The Motorola DROID Bionic and ATRIX 4G allegedly both suffer from a power management fault that could lead to the smartphones overheating even when idle. According to trusted source kbman at HowardForums, his contacts involved in testing the smartphones claim the issues could affect radio performance among other things.

“The problem has to do with the PMU and causes a variety of issues including severe overheating even while at idle, power fluctuations affecting RF performance and cold boot issues”

More concerning are suggestions that the problem is “unfixable”, though another user claiming insider information claims the PMU problem is in fact due to be addressed this week.¬†While no specific evidence has been produced, kbman has a track record of inside Motorola information that is leaving would-be Bionic buyers wary of the new smartphone.
