    Lumia 640 battery drain

    Solved my problem, but it's a weird one. I noticed my phone was constantly searching for my family mobile network, because it couldn't keep a stable connection. I took it out of LTE mode and my battery life is pretty much back to normal. I'm not sure why it started happening now, because it was...

    Lumia 640 battery drain

    Thank you for the information Hyrokumata. I'll be looking into the Device Portal. I just did an update and it has OS 10.0.15063.414 - I'm not sure what OS I was running before the update. I'm hoping this update might fix my problem. The batteries were bought from amazon and ebay with the...

    As far as I can tell it does. When I go to make a call the Wi-Fi symbol is showing instead of LTE. I don't know a 100% way of knowing for sure though.

    Lumia 640 T-Mobile windows 10

    I'm not sure what I did. I got sick of waiting so I installed the windows insider app. Then I ran the Windows upgrade advisor app. It gave me confirmation Windows 10 upgrade was available. It seemed weird, because it didn't seem to be part of windows insider. I then uninstalled windows insider...
