    I have charged my 6 plus to 100% from being drained to 0%, now do I want to drain the battery as fast as I can, then charge to 100%? Thanks

    So you've already drained it to 0% and then charged fully to 100%?

    If so then that's all you need to do, don't continuously drain to 0%, that can damage the battery a little (one of the few things that are bad for lithium ions). You only need to drain to 0% and back to 100% once a month or so for optimal results.

    The phone came charged at 70% today, then over the course of 10 hours I drained it to 0%, then charged it to 100%.

    It's good then, it's recommended you don't do it again this close together, it's to no benefit and if anything could do a little harm.

    Ok then why are you asking if you should drain to zero again? You've just calibrated it..

    Apple appears to have removed all references to iPhone battery calibration from their site. It's no longer needed on the MacBook line. I wouldn't worry about calibrating your iPhone battery.

    I agree with the above. It's not necessary to drain the battery anymore. If you feel like the battery meter is wonkey like it goes down then all of the sudden goes back up, then you may want to calibrate the accuracy.

    Just use your phone normally and don't worry about it.
