    My battery (Lumia Icon) is draining at an unusable pace doing almost nothing.

    My phone intermittently heats up (a lot) whenever notification center, battery saver or Cortana decide they need to do something.

    I can literally tell when I get an email because my phone gets hot. I used to get to the end of the day with 60-70% battery left and now it only lasts to my lunch break because I'm not using to do anything but adjust settings.

    Among other things I've noticed:
    1- Notification center triggers massive power drain and heat
    2- Batter saver doesn't close when you back arrow. You have to hold the back arrow down and press X to close the app.
    3- Several times when taking the phone off of stand by it shows "Resuming....." and proceeds to drain battery until it goes back to start screen.

    I turned off everything to do with Wifi Sense and have had a huge improvement. Might be even better than before 8.1 now :)

    I posted this in another thread thanks to a few peoples help... Turning OFF the battery saver actually increases battery life... Since I turned it off I have been heavily using my L920 for 4 hrs streaming videos HD and music, downloading music, sending files via Bluetooth, recording 1080 videos, instagram browsing, playing with Cortana. 74% and I'm pretty happy overall now.

    Same here on L920, though it must be because I keep chatting with Cortana, and have lots of background stuff.

    Maybe its Cortana draining all these devices. My battery improved with 8.1 but I'm in Canada so no cortana

    I am seeing the same problem, on my Lumia 1520 I have noticed several issues around the battery. First, the upper left corner of the device gets unusually warm (I have never noticed this before with the 1520). Secondly, the battery take a very long time to achieve 100% charge, sometimes I will charge it overnight and it may get to 95%. And lastly, worst case, I have had my battery drain after about 3 hours unless I keep it plugged in and charging throughout the day. Its actually quite unbearable at this point. I have tried soft reset, hard reset, completely wiping the device and starting from scratch and nothing seems to help the situation.

    i saw in my friend's lumia 520, even though he was playing around with his phone, his battery saver showed no current usage.. and on the other hand my battery saver showed plenty of apps running in current usage.

    Too many of these threads. I posted this in another battery thread.

    When you go into Battery Saver the default view is the usage. I went through all of the displayed apps disabled background on all of the ones I saw. A day later and my battery was still draining way too fast. Well, I went back into Battery Saver and at the bottom of the list I noticed the 'show all apps' link. I clicked that and voila, I had a dozen apps with background activity still enabled, a few that I knew were power guzzlers. I turned them all off about 15 minutes ago and my phone doesn't feel like a mini-space heater any more. I have it plugged in so Battery Sense hasn't updated to show what my per-hour drain is yet, but I will post an update soon.

    3,000 mah - 4,000 mah should be the standard battery capacity of smartphones nowadays.
