[sanuj_bhatia_54]

I have installed WP8.1 developer preview on my nokia Lumia 820...but battery life very bad! Uts only 1650 mAh n then preview sucks it more..so should I hard reset my phone to improve battery life n remove bugs?

soft reset is like a reboot/ restart whereas hard reset will erase all the content from your phone , removing all the data including images , music and user settings. You have to re-download all your apps after a hard reset.

Do a soft reset for the mean time. You'll be good.
