    I just recently replaced my iPhone 6S for an iPhone 7, but I've been having a pretty bad issue which is the fact that the battery is dropping way too much even if the phone is idle. Just to give an example, if I leave it overnight without any apps running, the battery drops about 50%. The only way that I found to avoid this is by leaving the phone in Airplane Mode. In this case, even if I turn on the Wi-Fi (so I can keep receiving notifications, etc) the battery doesn't drop at all overnight. This is obviously not an ideal solution though especially when I go out with the phone and there's no Wi-Fi.

    Here are a few of the things I tried:

    1) Resetting the phone -- didn't work at all, I even tried leaving the phone without any content (no 3rd party apps, no photos, etc) but the problem remained the same.
    2) Disabling Location Services -- didn't work.
    3) Enabling Low Power Mode -- instead of dropping 50% overnight, it drops about 30%. Still far from ideal.
    4) Disabling Cellular connection only, then disabling both Cellular and Wi-Fi -- none of the options worked.
    5) Updating to iOS 10.2 Beta -- didn't work.
    6) I also read the "iPhone 7+ Overnight & Standby battery drain" thread and tried some of the options listed there to no avail.

    The Battery screen on Settings does not help me much, as the apps that are listed there and the times that they have been used definitely do not correspond to the amount of battery that is lost.

    Everything points to a hardware issue, but what gives me hope is the fact that on Airplane Mode the battery seems to work fine. Do you guys have any idea of what I could try to do to fix this? If there's any setting that I could try changing or anything like that... It's been a huge problem for me and I really don't know what to do anymore.

    Is your signal strength the same as it was with the 6S? low signal will eat at battery easily.
