    I'm on the phone with AT&T complaining and they said according to their notes that on Monday when the software update is realized to is supposed to fix battery issues as well...oh how I don't believe them
    Well I'll be on a trip next week. So we'll give it a chance next week with that update and if it still dies, going to have to exchange it for a Titan or something else.

    Thanks for the tip, Bill.

    My current voltage is 3.655 and Current (Discharging) is ~120 mA.

    This is with Cellular Data on, WIFI connected. No apps in the background, BT off, Brightness low and vibrate off.
    With similiar settings, I am getting really good battery life. My battery drain shows anywhere between ~100-120 mA. I set my brightness setting to Automatic. XBox updates off, Bluetooth on. I think if you are away from your known WiFi it will keep searching and drain battery. When I step out of my known WiFi spots (home, office etc.) I switch off Wifi.

    I was home all day today and my battery was drained within 8 hours with very light use. I did have Wifi on though. Going to test if battery life is any better on a full-charge with Wifi off.

    So I am doing a test now. I completely factor reset my phone last night and drained the battery until it shut off and then did a full charge to calibrate the battery.

    I have BT on, WiFi off, Screen set to 30 sec. timeout, Medium brightness, 2 emails on push, and 2 live tile apps running in the background (WeatherMaster and PlusPoints).

    I took the phone off the charger at 7:30am this morning. It is almost 9:00am for me so roughly in 1 1/2 hours on pretty much no use I am down to 94%.

    I will keep you all updated.

    Bluetooth is a killer, I won't expect your phone to last the day. Let us know what happens.

    I always have had BT on my phones. My Focus, HD7, Focus S and Titan all easily lasted the whole day with the exact same setup.

    I don't think that is true...

    I have bluetooth turned on and get the same results under Battery status in the Diagnostic app....

    I am finding battery life to be the best I've ever had. Get about 20 hours with moderate to heavy use under lte with auto brightness on.

    tweetwp7 - I have pretty much the exact same set up on my new Lumia 900. 2 push email accounts, BT on, two livetile apps on with background tasks, WIFI off, screen brightness @ medium. Also I dont have LTE in my area yet.

    I unplug at around 9:30 am, and by 11:30 my battery is down to 94%. I unlocked it twice to check email and then locked it again.

    I used to have a Samsung Focus, with the exact same setup, and I could easily go until 3 or 4 pm until I hit the ~90% battery range - with much more usage on my part. I'm not even using my phone and the battery seems to be draining faster....

    Something seems wrong....

    Something seems wrong with mine as well. Not getting nearly the battery life I did on my Lumia 800.

    I wonder if the April 16th update will fix battery issues as well.

    The AT&T rep I spoke to said in his notes the Monday update is "supposed" to fix battery issues as well. I don't know how much I trust that.

    @Earle36 Also I don't have LTE in my area so I am running HSPA+.

    After I run the nokia diagnosis, what should I see? My voltage us 3.883 V and 115 mA. I have no clue if these are good numbers or bad. Is there a chart or something I can compare these to?
    Thanks.

    Another 1 1/2 hours passed and 58% battery...I am not even on LTE. Also all background tasks are turned off.
    Someone may have mentioned this already-
    run the battery out completely 2-3 times. Mine was pretty bad until I let it calibrate by running it til it turned the phone off, then charged to full. Now I'm getting pretty good life out of the thing.

    I have done this since I got the phone on Friday and no luck...

    That is what I am seeing too. No issues here. I What is the estimated time remaining on your Settings > Battery Saver?

    Also keep in mind that your battery life depends on your location and distance from tower, AT&T network settings etc.

    I've never even for a split second seen mine jump under 102 mA. I wonder why.

    It has been another hour and I am down to 84%. I haven't used the phone at all in the last hour. The estimated time left is 1 day and 5 hours, but we know that is a lie.

    Also I submitted this issue to Mary Jo Foley at ZDNet and she responded to me...so maybe since she has some power in the tech world, we can get some answers from Nokia.

    Mine seems terrible as well, at least compared to my iPhone 4. I have only 1 live tile updating weather once an hour. Disabled just about every apps background abilities, no email syncing, just wifi and 4G (200 yards from tower, not LTE). Was 85% when I went to bed and 8 hours of idling later it was 74%, not sure if thats bad but it looked like it. Playing Wordament I can practically watch it drain, and poking letters doesn't seem that intensive. Don't think I could make it through the day with even light use.

    So another hour has passed and all I did was check my Twitter feed. My battery is was at 84% an hour ago and now at 80%. It is getting slightly better but that is still 4% in an hour for checking a Twitter feed for less then a minute.
