Hi i was wondering whats ur life time in lumia 620 ? Mine is 10 hours with 100%
I charge it twice per day .......... Its so boring since i bought the phone the battery life is the same
What about you ? Should i change the battery
Do you have double tap to wake enabled? I have read it degrades battery life more than glance so try disabling it if possible. Also if possible do a clean flash using Nokia Product Support Tool for retail.
Accuweather has always ate the battery on my icon at a high rate.. Try a different weather app. That may help you a little.. The weather channel worked ok for me in 8.1 and now running the 10m preview ms weather app has done me a fine job..
