    I've just got the phone. I use Internet sharing for about 3 or maybe 4 hours a day(sometimes more) and the battery lasts for about 20 hours or less. Also since it is a new phone, I tend to play with it a lot to see what's what :D

    Another question: How long does it take to be fully charged? Mine went from 9 percent to 100 in 3 and a half hours.
    Thanks

    what backup you are reporting is an average for every mid-range device. in under heavy use mine gives about 12-14 hours with heavy gaming and music. overall in mild use i get a backup on my 730 for a day+. But with recent windows 10 build on production my device has been raining charge quickly..

    Are you on windows 10 or 8.1?

    I'm a fairly heavy user on 1520 (insider).. 12hours per day is at the absolute max duration I can get. My usage
    - WhatsApp and Telegram (multiple work groups chats)
    - No movies, music, games
    - No usage of GPS/Maps
    - No Wifi, although I would use the phone as hotspot to my laptop a few times a day.
    - Black theme on all apps where possible,
    - Nearly all notification and vibration switched off, very few apps allowed to run in background
    - Heavy on Edge. For my most used fave sites, they get pinned to my start screen. Especially true for Facebook, that's very poor app (freezes, etc). Edge is highest on battery usage
    - Photo editing (usually L.Creative Studio, Fantasia Painter, etc
    - The carrier signal is strong,
    - No usage of OneDrive except when I'm at home on WiFi (which is after the 12hours workday)

    The 1520 is nearing three years, so overall can't complain about the battery duration (15-25 % left after 12hrs) . I was using a brand new 1520 recently, with near identical setup/settings. . battery duration was just slightly better.

    ...!!

    Heavy use with 640XL on Fast Ring:

    From 6am to 8pm, have 30% left on average.

    Blows away old 950XL, which would be dead in 5 hours.

    640XL is a beautiful beast

    I recently picked up a 640XL and updated to Anniversary update. The battery endurance definitely took a hit. Charged it to 100% this morning and took it off the charger. After an hour of moderate use, it drained 11%. For those that are running insider builds, does the battery life improve on this device? Is Microsoft making headway in improving the power draw of W10M. Let me know. cheers!

    Glad to know the battery life is pretty solid. I just grabbed one for myself from the sale.

    I think the 950xl has bad battery life is because of the OS and the Screen pushing all those pixels

    W10M Release Preview user here, i think that WP8.1 on our devices is still better than the current W10M release. Maybe due to some under the hood quirks...

    wondering the performance about this beast.

    I sold my 920 and the reason is facebook apps loading time is killing me.

    How about the loading time on 640 XL?

    Facebook takes 15 seconds to load on my 640xl. Currently on Win 10 mobile release preview (12-9-16). Other apps open much faster, though 15 seconds is meh tolerable.

    i am very happy of this 3000 mah beast. When switch to battery saver mode, the battery only drop 1 percent for 8 hour.
    With my usage, it can stay away from charging port for at least 24 hours.

    The only things i don't like is, why facebook will take 12 seconds to load ?

    Try SlimSocial as an alternative app for FB. I hear that it works well.
