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.
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.
I only calibrate like every 2 months
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.is battery calibration still needed nowadays?
