    So i updated my Lumia 820 last night. New features are quite great and Cortana is unexpectedly impressive.
    But the problem is, i think, my phone battery is running out faster than himself in 8.0. Here is my conditions after I fully charged:
    - have Wifi on, 3G on
    - running Viber, Skype, LINE in background
    - 3 email acc update every 15min
    - Double-tap, Glance screen (Peek)
    I left the phone alone for 3 hours, replied 2 messages, and the battery lost 17% back to 83%, while usually with 8.0 i only lost ~9-10%.

    Anyone has same prob? Any solutions? My bat is only 1650mAh, quite weak, and if 8.1 runs like this I think I would have to charge my phone 3 4 times a day.

    Definitely. The same with Lumia 720.
    Four hours ago the phone was fully charged and now it shows 82% with all background tasks disabled.In wp8.0 it looked much better.

    Yep... Same with my Lumia 925.... This may be why the newer Windows phones are getting bigger batteries I guess?!

    So WP 8.1 is a deal breaker for Lumia 520?

    I think Nokia and MS should have a new project to make bigger bats for old-Lumia phones, you know, making the bats double capacity LOL

    I have probably used the wrong expression! I have a Lumia 520 and I am very happy with it, besides being a bit slow (anyways it is the Lumia entry line, so I should expect too much), what I really dont like on the phone is how short the battery lasts. So I am wondering with the WP 8.1 the battery life worse at 520 or if the effect is only marginal. If the battery life is a way worse I wont update the phone for the 8.1.

    It happens to every phone i think. Stick with 8.1 for a while and let's wait if your phone can get along well with the OS :) hope MS can fix this

    This was called preview software because it would have some errors. Microsoft didn't force this update on you. You chose to download it. More importantly check all the apps under battery saver, many apps have been enabled to run in background. Disable what you don't need, should be better off.

    I would venture to guess that the increased use of GPS is to blame. About 5 minutes after I got home last night, the test "remind me when I get home to beat a cat," which should have been "feed the cats," popped up. So it has to check GPS occasionally, and with experience from some weather apps that used GPS to update the live tile and lock screen, it tends to be my worst battery drain.

    Im with you guys, same problem here.

    Yesterday I saw some forums about this problem, and I was recommended that let the battery runs out completely, and charge again completely, repeat some days ... I'm doing this right now.

    Mine's definitely draining faster on my HTC 8X (probably 10-20% faster). I suspect it's a combination of how hefty a process Cortana runs in the background, the amount of time she spends accessing GPS (as mentioned) and the OS may need to re-learn your usage after the update. I know when I first got my phone it burned the battery to less than 20% in under 8 hours. After it learned my usage and adapted itself I was getting about 36 hours on a charge relatively easily (not that I would go a night without charging it anyways). It may have just lost its marbles a little bit and needs to re-teach itself.

    Nope. The 520 is excellent with WP8.1. Im running it and loving every minute of it.

    Sure, the battery drains faster, but I do play around with Cortana and such so that could be the cause.

    WP 8.1 seems to drain the battery faster on my HTC 8X, even with GPS and Cortana disabled. One thing I've noticed since GDR3 is more tasks keep running in the background unless I 'X' out instead of using just the Back button.

    Also, is it my imagination or is IE11 slower?

    My Nokia Lumia 625 battery management is definitely better. I uploaded it about 10 hours ago and Its battery status is 72%. The Wifi and GPS is running all day and I often talk with Cortana.Today, I explored the new feature and it was always in my hand.

    I tried Cortana for an hour and she is really fun to be with. Unfortunately, I must turn on "Location Service" for Cortana to work. So I uninstalled her by changing region again. Location Service + Cortana = Huge Battery Drain.
