    how did you get the redstone build on L640? I heard it's only for devices shipped with W10, looks like the battery performance is good on the redstone build

    I have single-SIM LTE on W10.
    Usually I get 3 days of battery, then charge overnight. As you would guess, usage is quite light ;) Most everything is on: data, wifi, gps, nfc and bluetooth, no extra settings in power department. Battery life was very good on WP8.1 and also is with W10.

    is this on 4G always? 3 days is too good to be true... I would say very good battery performance then...

    I don't measure it that precisely, because all I care about is getting a full day without charging and I can do that regularly. Lumia 640, W10, build .164, on wifi 50% of the time, light on apps, I mainly use the phone for communication via text, email, and calls, but I also read the news, Twitter, weather. Do not play music or run the GPS most of the time. I plug my phone in over night and run all day long until bed time--that's all I need.

    Windows 10 Mobile Production, so thats .164. (no Insider, although I did enlist it in the Release Preview ring after upgrading, but there's nothing yet.)
    AT&T (LTE) - however I flashed the phone to the Argentina variant ROM two days ago, so performance could change.

    It was off the charger around 7:40-8:00 AM today.
    It's at 76% right now, which is just a tad past 2:00 PM. (so 6 hours)
    UPDATE: I am at 62% just at 16:53. (so 5p)

    UPDATE 2: It's coming on 20 hours off the charger and it's at 12%.

    Use has been light-ish. A couple photos, maybe an hour's worth of Groove offline playback. Light messaging, poor to nonexistent Wi-Fi. Maybe 10+ minutes of WC.

    Regardless, it looks good thus far. If I get 24 hours of my usual usage out of it, I will be pleased. (which would translate to maybe 1.5 days if standby power usage is decent.)

    for anecdotal reference, the iPhone 5s would last 14-18 hours, the Galaxy Alpha would be more in the 11-15 range, Pre 2 in the 10-13-14 area, my Lumia 920 was in the 12-16 range. (until it hit consistent 10's, but the battery was getting old)

    Now those numbers are just my feel for their longevity, I don't have hard data and of course, it could all vary. I used the Pre 2 a lot less than the others over the course of a day for example.

    My 640 is not my primary phone, so it sees light usage. It has seen about 10 texts, 4 mms, and 10 minutes on wifi. Last charge 14 days, 23 hours.

    The phone show 2 days remaining, but it has been like that for the past 14 days. I think it has enough battery life for 5-7 days. Wifi, BT, GPS, and data are off except when needed. Phone is still on WP 8.1, T-mobile LTE standby.

    My 640 used to run very good on IWndows 8.1 (Morning 6.00 am to like 8.00 pm around 40 with moderate usage and 4G and still remaining on 30% - 40%)

    on Windows 10 the phone goes to 30 around 5 PM if I'm on 4G whole day. For the last few days I have set the Data connection to just edge, so that i don't have to worry about battery life until I reach home.
