Re: lumia 920 Battery Issues
I had pretty good battery life, lasting all day from 8 to well past midnight, pretty much always having decent charge still available most nights, unless I had very high usage. After the update, it seems it was not as good, so I tried the soft reset others had suggested, and it looks like I am back to normal decent battery life. I have had it on for over 11 hours and I still have 42% of the charge left. Before the reset, I was running out by the end of the day. I am also back to it staying at 100% charge for several hours after I take it off the charger in the morning. I always exit out of apps when I am done with them pressing the back arrow to get to the start screen so I do not leave unneeded apps running in the background, and I have a most of the background operations blocked in the settings for apps I really do not really use much. I am on wifi most of the time, though when I am off WiFi and on cellular data, it seems to still last as long, or maybe longer. If you have not tried a soft reset since the update (holding volume down and power pressed), it might be worth a try to see if it helps.
