One of the Lumia 920′s claims to fame is its super-sensitive capacitive touchscreen, even detecting fingers obscured by gloves. If it’s that sensitive, though, won’t the screen go nuts in your pocket, picking you up even through layers of fabric? There’s been some concern that these issues might lead to abnormal battery drain. Nokia’s now attempting to nip such rumors in the bud, explaining why the 920′s great touch sensor won’t mean you’re charging your phone every few hours.

The concern is that a physical button on the phone would get nudged while asleep in your pocket, and once the screen powered-up, it would keep detecting errant non-inputs until it drained the battery. Nokia says this won’t happen, because of the way it’s configured the phone’s firmware. It’s put in a requirement for a “landing event” before the display goes active, one that would be tricky to occur accidentally.

Nokia says that in all the tests it’s run, it hasn’t noticed any problem like the one this rumor speculated upon. So, worry not; you’ll be able to enjoy the 920′s sensitive display without penalty.
