    The discharge speed has been coming down (had the app for a while so the average doesn't change quickly) for a couple of weeks now since I had a WiFi issue that was eating battery up. That seems to be resolved and I have been going 2-3 days without needing to recharge. To be fair I am not a heavy user but I am still impressed.

    That is great.

    Only 2 years ago, a smart phone meant just accepting battery life stunk, with the only exception being BlackBerry. Now, we are seeing more and more that battery tech and the software design of OS's are starting to catch up with that.

    I would LOVE to go 2 days on a charge. My L920 does eat battery charge quicker then any other device I have ever had, so I am looking excitedly to the WP 8.1 update.

    Turn off battery saver and stop it from running in the background. Very odd but greatly increases battery life!

    I get about 12 hours of screen on time with my 1520 so depending on usage o get between 3 and 5 days out of each charge.

    How many apps do you have installed on your device? One of the threads I was reading over the weekend suggested uninstalling unused apps which I had a bunch of so I did It freed up storage space and along with being more careful getting the 1520 into the case without the camera app starting or being started by the case flap has settled the battery drain quickly. I tend to hook it up either at the office or home are car if its draining more than I'd like. Its a habit I have been doing since the early days of converged devices/smartphones like the treo 600. Too many chargers may not be enough.

    My own experience with my Lumia Icon is that it simply sips on the battery. Never drinks. I've gone a solid day (9hrs) of mobile hotspot use and still have about 15% life left. The phone is excellent in the battery department. 😊

    Granted I have Data Sense disabling background Cellular data, I recently went to an out of town wedding. After ~26hrs I had 50% battery left and I was messaging people, snapping pictures, etc... Had Wifi at the hotel and Wedding Hall, so there was still background data going on. I was ecstatic compared to what I'm used to on my 1020. I had fully planned on using my 1020 on vacations, for the camera and incase I lost my device (my 1520 is an ATT Next device, needs to be returned), but now I don't know.

    Well, mine too, if i dont use it!
    I got the 620 (ok, with a better battery in it), if i dont use it i have the same: 3 days and 50% left. And i dont close apps or care about background blabla, location is always on!

    BUT: If i use it, its gone after few hours. Like every phone, there is no special longlife-wonder-phone!

    Yea..no you are wrong.

    The Lumia 1520 has the best battery life of any phone I have used to date. I get on average 2 days with heavy usage. This is the first phone I don't charge immediately upon getting home at night, and feel confident it will work all the way till next evening with heavy usage.

    I have EVERYTHING turned on, location, fb, etc.. Literally nothing turned off. I use LTE all day mainly as well and bluetooth in car. Hell I dont even turn off bluetooth or wifi even if there is non around.

    620 is NOT 1520. 1520 has an absolutely massive battery and it shows.

    Agreed, 1520's battery was awesome, under 8.0, but it's EPIC under 8.1 - the second dp update.

    I've just driven from Paris to Calais (3 hours) and am for and a half on the ferry AND then a further one and a half hour to London and home: Drive + ALL the way, with a Bluetooth headset - 56% battery left! Now I had the screen set to medium brightness but hey. EPIC. That 3000mah battery is brilliant.

    It's kinda weird, when I first installed 8.1 my battery drain was horrific the first day or two. So much so that I was considering reverting back.

    Then, all of a sudden, it drastically improved. I didn't disable anything or change any settings that I was using on 8.0. It just kinda self-calibrated and now I'm getting at least 2 days worth before I need to stick it on the charger.

    Considering the screen and power of this thing, that's pretty incredible. I'm not a moderate-user either so it's even more impressive.

    You guys must not be using your phones very much. My phone comes off the charger at 8:00 am every morning and by 5:00 pm, I'm at ~50% charge. Lots of phone calls, texting, 3 exchange accounts, some navigation using Waze, some Nokia MixRadio Bluetooth audio streaming, and not to mention the 15 apps I have running in the background. If I use it hard, by the end of the night, I'll be at ~20%. Battery Saver will usually report around 22-24 hours in the morning.

    I'm actually very happy with my battery life. With my 920, it would have to be on the charger by 5:00 pm..

    I'm so amazed on how good battery lifes you all get. My 925 is a whole another story. Watching Netflix is big decision to make because I can barely watch more than 3 hours and IE kills it around the same time. I said I'm a medium-heavy user and after waking up at 9 and going to bed at 10 my battery would most like be dead. I have to charge it through out the day which is a pain. I do feel like the battery is starting to get better (I have 8.1 since the first day) I'm hoping after a little bit more tweaking ill be able to achieve battery like all of yours

    925 will never have the battery that the 1520 has

    With my 925's I can get around 5 hours screen one time depending on what I'm doing. I don't use my phones for gaming.

    I try to judge by screen on time if I can. I have kept an account of my screen on time on for a couple of discharges and he least I got was 10 hours and the most was 14 however I only use my phone for web browsing, email, music and location on all the time for Cortana and maps (not satnav)

    I never turn Bluetooth, data and wifi off.

    This is real. I am a HEAVY user. Phone, text, Skype, IE, numerous alarms, Weave, Bing News, Podcasts and Xbox Music all day. Over 250 apps installed. Yesterday, throughout all that use, my 1520.3 consumed 1% per hour. ONE PERCENT.

    I suspect some of the batteries with smaller runtimes these days are due to the phone batteries being a couple of years old and not holding the same charge. Latest 8.1 is the best so far here - got a couple of days with light use which was a first for my 920.

    I also haven't noticed it burn its way through the battery. Yet.

    Also to boot the 1520 has an insanely large battery compared to the other phones in the WP's line up (though it does have a biggest screen). The battery life is probably down to the improved efficiency of the snapdragon 800 SOC compared to the older SOC's.. Also MS did say they believe they can make current smartphones last a week with tweaks, so therefore the Cyan update should make the 1520 even more epic in regards to battery life.

    Therer have been several apps that have come out or have been updated and I decided not to reinstall them or download them until I determine that I'm going to use them. I'm trying to be more disciple at least until I get my microsdxc card in a few days.

    Sure, the battery in 1520 is huge and battery life is great! Thats not what i mean!
    But if someone got another "normal" phone and says "yeah my batterylife is 3 days", then it indicates that he doesnt use his phone. And so every phone can have 3 days batterylife if you hardly use it...

    There is NO MIRACLE BATTERY WONDER in any phone. Its useage, brightness, apps, battery size. Done.

    I don't know what you guys call heavy use. But I wake up at 5.30 am every day, and by 5 or 6 pm , I have to plug it . And I do use it super heavily: constantly browsing, GPS, streaming music and videos , WiFi, lte, bright screen, etc.
    I don't have WP 8.1 yet. I'm waiting for the official release for the 1520 on att
