    so this has been a 1 month long issue with my iPhone only draining when connected to wifi..had my 6 a month after launch with no issues..I charge my battery and 100% before I go to bed and when I wake up its drained over 50% I just recently had a new one sent to me and exact same problem right out the box NO apps downloaded or NO iCould backup and now my old 6 doesn't drain while on wifi with NO SIM card in it...already went to AT&T to get a new SIM card thinking that was the issue...any help/ideas would be greatly appreciated

    Try going to settings>general>usage and seeing what apps are using the most battery. It may be you're setting your phone slightly out of cell range and it is looking for a cell signal. That eats battery very quickly.

    I noticed today that I get the same usage using 4G as I do using WiFi. Whilst my 6+ battery usage stats over cellular are perfectly acceptable, WiFi use should increase on those surely.

    Whilst I don't have the OP's problem, it is still perhaps relevant?

    Ok, if you still look at the usage, what apps are at the top of the list?

    yea makes no sense how battery life would be better or equal on LTE/4G over wifi

    Nope. Apples spec for the 6+ is:
    "Internet use: Up to 12 hours on 3G, up to 12 hours on LTE, up to 12 hours on Wi‑Fi"

    So you shouldn't get an increase on wifi technically.

    The 6 is a little different:
    "Internet use: Up to 10 hours on 3G, up to 10 hours on LTE, up to 11 hours on Wi‑Fi"

    OP you have something hung up (maybe email acct or iCloud backup) causing that drain. It should not drain 50% overnight just on standby. Something else is running causing that drain. You mentioned it doesn't drain on wifi when sim is not in the device. So apparently its not wifi causing it as the thread title suggests. I would reset network settings and see if it clears up. My guess is it will.
