    I upgraded my Lumia 1020 to the preview yesterday. I left my phone off the charger overnight and woke up with only 3% drain over 7 hours. Also, the current usage rate is 0.87%

    Is the battery reporting screwed or has the performance really improved?

    I have 3 email accounts syncing every 30 minutes, glance on peek and double tap to unlock. have a bunch of apps with background tasks enabled (battery, bing news, bing weather, caledos runner, das image, whatsapp)

    My 920 dropped 5% overnight, a slight improvement from gdr2 under the same conditions. Too early to tell, will report more later on.

    My 920 on GDR3 dropped from 88% to 83% in 8 hours during the night.

    Need more time to test battery life but it seems it's improved compared to GDR2.

    Battery life on my 720 got worse after the update. Hope MS fixes this before they release it to the public.

    I think it's improved a little....Today, 1 call, and 3 texts with using Weave for about 20 min, MLB app for about 2 min and checked 2 email accounts at least 3 times, I pulled my 928 off the charger around 6:30 this morning, it's 9:43 and I have only used 3% it's saying 97% free.....

    Not bad, by this point during the day I would normally be around 83-90% by this point.

    Unless the battery reading is wrong and I cant be more accurate till I use it for a few days but, so far, if the numbers are right, it looks like it helped.

    If your still having problems with the battery, I might suggest to give your phone a reboot (after the completed message came up, I rebooted it again "vol down+power" for 10 seconds) and then report back.

    I thought my battery was good, for the first 30min didn't lose any battery, but since it's gone back to normal, 12-14% per hour without the most amount of usage (which has been bugging me recently). I hoped the battery would get better but no joy from my side, went down to 20% after around 6hrs.

    Yeah, it seems that battery is better (based on 1 day experience with Lumia 920):

    Remaining battery: 74 %
    Estimated time remaining: 25 hours
    Time since last charge: 10 hours (all day time, no night time)

    Data, WLAN (wi-fi), fb chat enabled and in use ...

    updated my Lumia 1020 yesterday evening. immediately after the update it was the same. I let it drain to shut down and charged it all the way. I then turned on background on all my apps, switched to LTE from edge and set my email to push from every 30 mins to get an accurate idea of any changes (the previous settings were in place to make sure I could get a full day on GDR2).after 5 hours and 6 minutes which included 1hour off Wi-Fi, 1 hour of calls, about 10-12 pictures, some texting tweeting and about 3 pictures to Facebook and 3 to 6Tag, I'm now at 82% which is much better than it's been before considering how much I had it limited previously. I'll report back once I've drained it down to 0 to let you know what my final results were.

    Battery is normal to me, i think its pretty much people wanting their battery life to be better which is doing it.

    I haven't seen anything out to the ordinary for me.

    Previously, i was able to leave my phone off charger over night for 8 hours and have no battery drain that is with bluetooth on, 3 emails, 2 coming as is and 5 apps running in background. Probably would do the same now if i tried.

    The battery life on my 920 (AT&T) got worse. It seem to have improved after GDR2 but GDR3 is so far decreasing it a lot. The 920 also get fairly warm doing nothing after GDR3. Any suggestions?

    I'm pretty OCD about things and I can say for sure my battery life is much improved and my phone also runs cooler.
