    My battery life is really good.

    Leave everything on (BT, WiFi) all day and have a couple exchange accounts and a google account getting email all day long. I stream audio over BT on the way to work and home (about an hour total).

    Can last me all day and all night before I need to recharge it. Right now im at 73% remaining (7 PM). Had a couple of calls totalling about 30 minutes. Played a game for about 20.

    I have very strong signal both at home and work and am almost never on WiFi...guess I should turn WiFi off to get even more battery life.

    Think signal strength may have a lot to do with it. Also I just turned off the two options on Find My Phone since I never use that. I do have gMaps running in the background though.

    The day I got my Lumia 900 i fully charged it and it has an estimated time remaining of 1 day 12 hours. The phone lasted a long time with heavy usage and everything on. Location on, brightness high, WiFi on and connected,2-3bars LTE, 3 email accounts manual sync, battery saver off, find my phone on, update on, feedback on. I have 1 live tile and that is weather.

    My phone got hot when I was streaming a youtube video and I had it charging. Then the next morning my estimated time remaining was 10hrs. Some days it is 12hrs. My battery dies in 5hrs with heavy usage now and everything off. WiFi off, brightness low, battery saver on, update off, feedback off, find my phone off, cellular data off(occasionally turning it on).

    Also when battery saver and nokia diagnostics says there is 0% battery life remaining, I usually get about 30min more of heavy usage.
    Right now this phone gets worse battery life than my Samsung Focus and my focus' battery life was bad.

    I have noticed on some occasions after a full night of charging the battery, the Remaining battery life = 99%.

    Estimated time remaining = 16 hours

    I'm not sure why it does this because on other occasions it says

    Remaining battery life = 100%

    Estimated time remaining = 23 hours
    While on charge, once your phone reaches 100% it will drain back down to 98-99% (sometimes even 97%) and then go back up to 100%, cycling up/down every 20-30 minutes. I have tracked this using the homebrew Battery Meter app, which graphs the current battery percentage every 10 minutes. This keeps your battery from overcharging.

    This is the first phone that I could leave my Bluetooth and WiFi on all the time without worrying about battery..and I can easily get 24 hrs of usage. To the OP, poor signal definitely kills battery life.

    I think my issues are related to poor service while at work. On the weekends at home with 5 bars of sig I seem to have no issues.

    Went to Detroit last night and took a bunch of pictures, uploaded some...used 25% in 5 hours. That seems acceptable.

    I too had bad reception at work. I changed my email from as items arrive to every 15 minutes. This helped a ton. My battery life has since been very long and I do a lot on my phone throughout the day. I also find this is the first phone i can leave WiFi and Bluetooth on all the time. Though I do normally turn off bluetooth as i only use it in my car and it does still do extra drain on the battery.

    My typical usage is 9AM - 11PM with a bunch of texting and a bit web browsing then a 1-2 hour phone call conversation at night before I sleep and I usually have about 10%-20% left. My phone's battery is a champ, IMO. 4G LTE and WiFi both on. Medium brightness.

    I don't get it.

    I take the phone off the charger at 6:30 am. 30 minutes of phone calls and 30 minutes of spotify streaming and Im at 53% battery by 11am. No other apps in the background, no live updates except weather which updates every 30 minutes.

    Is it possible I have a dud? Am I doing something wrong? Is there a way to see where the battery leak is coming from? I keep my brightness on medium.
    People who like the phone with overestimate their battery life (intentional sometimes, other times not).

    People who are unhappy will underestimate it (same caveats).

    Heavy/Moderate/Light use are subjective terms and you can't really take those seriously. That's why there's a return window. See how the phone performs for you personally and then figure out if it's good enough.

    Smartphones typically all have poor battery life unless you mod them with optimized Custom ROMs or they come with huge OEM batteries (Razr Maxx, etc.) to extend them (or use a 3rd party extended battery that turns your phone into a brick). LTE phones are generally worse than 3G phones.

    Using the Cell Radio over WiFi will almost always lead to a decrease in battery life. If you live or work in buildings where cell signal penetration isn't so good, it will obliterate your battery. Try to use WiFi in those instances.

    Use Black Backgrounds/Dark (assuming the dark is black) themes in all apps possible on an OLED screen. That will also save some battery.

    I was expecting battery to be a bit better personally. My iPhone 4 was a champ - I'd say it would run 2 to 3 times longer than my Lumia 900 does on a charge.

    The iPhone4 has a tiny screen and no LTE. The screen is easily the worst battery sucker there is, you think Apple doesn't want to introduce a larger screen? I bet they haven't figured out how to do it and then join the rest of us in terms of battery life.

    My battery life has been great on some days, not so great on others. But I'm always doing different things and in different parts of the city. I've gone 18 hours and had it say I have five hours left on battery saver. It's just something you stay on top of, give it a bump charge mid day if you had heavy use in the morning, etc.

    Something I noticed is I get bad battery life depending on location, not much more on the signal strength according to the phone. I will be getting 4/5 bars in the hospital, and the drain is like 200-600 with no apps running, and also after a restart, and when I'm back at home, I get the nice idle of 90-100. I notice that I can go about 1.5-2 days with moderate use back home, but when I'm back at university/hospital, it's back to daily charging. Signal strength wise I have 1-2 bars at home. That's been my observations so far.

    so where I work is like a tin can with approx 1 bar of service...does this effect battery at all? approx 1-2 bars of service.
    That'll do it.

    You might try turning on the battery saver setting. If you don't need email pushed to your phone constantly, most people don't if they are sitting at a desk where they are getting email anyway.

    The battery saver setting will make a huge difference, with that on you'll still get text messages but you will only be using a lot of energy when you're actively using the connection.

    Personally, I keep the battery saver setting on at work, I don't have live tiles updating constantly, I stream music for about 3 hours a day though using my office WiFi, check email on the phone periodically and make phone calls and send texts. Doing that my battery easily lasts all day. I usually have 30-35% when I get home actually.

    Even if I forget to turn the battery saver on, I haven't had my phone die on me before the end of the day once. I do have good reception in my office though, usually 4 bars.

    Socialcarpet (sorry, can't quote with Board Express), Battery Saver only kicks in when your battery drops down below 20% and the little heart appears on the battery meter. It does absolutely nothing otherwise till it reaches 20%. No need to toggle it on/off. Ihave had it active on my L900, since about an hour after taking receipt, and I get mail, updates, etc., all day long, till my phone drops below 20%.

    There are two checkboxes.

    Always turn battery saver on when battery is low.

    and

    Turn battery saver on now, until next charge.

    If I have both checked, I get considerably better battery life on my phone, and it does not check my email until I use the phone.

    I stand corrected. Learned something new today.
    Thanks for pointing it out.

    Personally, I couldn't deal with this. No email updates, no background tasks. Not even sure you can do app downloads on battery saver. I know I have a couple apps that won't update while on saver. Why have a Smartphone if it can't work smartly. Background updates are at the core of what WP is. That's why I have a handful of portable USB chargers. My phone is seldom below 50% for very long. But if it works for you......whatever.

    Had another bad battery experience this weekend at a wedding. Off charger a little after noon. Ceremony was at 2:30pm. Checked twitter and some scores for minutes while waiting. Took a few pics right after the ceremony and at the start of the reception.

    Around 5:30 in was in line to get a one more drink before dinner officially started. I pulled out my Lumia to check a score and the battery was at 53%....it was also quite warm feeling. So something got "stuck" and was just running. But the battery and background systems on this phone are just not reliable.

    I had full signal of HSPA+ the entire time. After a rebooted the drain seemed to stop. I made it the rest of the night down to the battery saver coming on. But I just got really annoyed I wanted to show off the Lumia and here it has a major flub.

    All this and my buddy's (the groom) Indian family were all ogling the Lumia the entire night.

    Trust me if you're getting that kind of battery life you're below moderate use, and probably on WiFi the entire time which is a completely different usage scenario than someone out and about using the carrier network for data (which drains a ton more battery).

    I've had a couple lockups/overheating but they happen infrequently. Seems like I can stream audio or just play music (Zune local) and just about do the same on battery. WTF is up with that?

    Incidentally - I ran my wife's LG Nitro HD (Android) w/ Cyanogenmod 9 (getting ready for ebay selling) and man I have nothing to complain about. Less than 8 hours of battery on moderate use. At least the Lumia seems to be able to handle 12+ hours of moderate use.
    That's because your iphone4 was not LTE, L900 is LTE. LTE will drain battery a lot until the towers reach the full capacity and you find good strength everywhere, till then it will keep draining.

    I think that was a reasonable battery life. You are making this a big issue than it is.
    I have had worse experience with my iphone4s than you are having. I consider this as an improvement over my 4s.

    Yup. I toggle back and forth. If I'm in the office, I don't need email coming to my phone. As far as weather or news apps, I don't need for them to be up to date the second I turn the phone on, it's no bother for me to tap a tile and wait the 1.5 seconds it takes to update. I'm usually not checking weather or news on the phone when I'm at work anyway. I have a charger on my desk at work anyway, but I rarely need it.

    When I'm not in the office, I uncheck the second box so my email gets pushed through, also when I'm not in the office, I'm much more likely to be checking news or weather or other things then, so the background updating is actually useful to me then.

    Works pretty well for me. There's definitely a noticeable difference in battery life with that second box checked. But even when I'm on my day off and it's not checked all day, I've rarely have a day where I leave the house with a full battery and need to charge before the end of the day. That only happens if I'm using the phone like crazy.
