My battery life is miserable. It stated in the past week, though. Can't figure out what changed, but I'm at 5% or so battery left each and every evening now, with light use. Last Saturday I woke up and used the internet in bed for about 20 minutes and killed 25% of my battery.
Finally realizing the huge issue, I looked at the phone when I took it off the charger this morning, and it showed 18 hours left. 18 hours at 100% charge? I walked to work, about 20 minutes, with music playing and the screen off. 14 hours left. 93%.
It's at the point where I can't go morning to night without charging. And I am a light user - 20 minutes of talk, 20 minutes of music, maybe 20 minutes of internet (usually less) and maybe 20 texts. Bluetooth is off, WiFi is sometimes off, and music is local, not streaming.
So yes, battery life is a huge issue for me. If I were using this thing heavily I'd probably have to charge it twice per day.
The only background apps I've allowed are Weather Channel and Bing Weather. I may uninstall one to see if it's the drain, but I've never had a phone last this little - my 928 used to get twice this. And, like I said, I'm fairly certain this is a new development with this phone, but it makes me extremely unhappy with it. I think my headphone jack is broken as well - in-line controls don't work, the microphone doesn't work if the phone is in my pocket, and today the left ear stopped working. With two sets of headphones... I'm getting very tired of going back to the Microsoft Store with a defective Nokia phone.
