I never never download any software from anyone on my computer or phone

except the manufacturer (HTC, Microsoft, Toshiba).  I know y experience this

is asking for disaster!!!!

The only download that ever got on this phone from the day it was purchased

(November 18, 2011 from Best Buy) was the update HTC/Verizon installed in

May 2013.  That is when I started returning phones to Best Buy for this very

same issue and my 5th Thunderbolt has the same problem.  I know it is the

"update" that is causing the problem.  I've had the phone in airplane mode

for two weeks and it has NEVER turned off and the battery is still charged

to 50% (after 2 weeks! Without plugging it in to the charger) .

There is nothing wrong with the Thunderbolt as an electronic device. It's

the software update.

Thank you for your concern.
