So, at one time it was considered good maintenance to periodically fully charge and discharge the iPhone. I recall an Apple help article saying as much. Is this still considered best practice? I want to make sure I condition my iPhone 6 battery properly to get the best battery life.

Thanks!

It's not really necessary, but doing that every once in a while will calabrate the battery percentage.

Thanks! Any chance it could hurt the phone or battery to completely discharge?

It shouldn't. Lithium ion batteries have a set number of charge cycles if you drain it deaf then back full that is one cycle. if you drain it to half then to full you used half a cycle. Etc.

This is an endless debate, and has been since Lithium Ion batteries began being used in cell phones. The older mobile phone batteries responded well to the drain-to-shutdown-and-charge regimen, and made their lived a bit better...but most people smarter than me say that kind of thing actually doesn't help Lithium batteries at all, and could even shorten daily charge lifespan. From what I can gather, simply being consistent with your charging routine is the key.

I pull my 6 off the charger each morning at 6am...and with moderate to heavy use, I still have 20-30% charge left when I put it on the charger at bedtime each night. I usually had to plug my 5 & 5s in before my workday was over, so the battery life on my 6 is a huge improvement.

With a lithium battery, fully discharge and charge won't help. Your device has build in battery management. Engineers

This is my typical range. I don't leave apps running that I'm not using. Nothing is tracking my location besides Find My IPhone that I can control, and I only have one app allowed to do any background updating. I only charge my phone when it hits 1% or dies. I did the same with all my other iPhones and had no battery issues.

I also leave my phone on airplane mode overnight. I set it on airplane mode around 10pm and turn it back off when I get up. Not only does it save power it doesn't make noise or go nuts. Anyone that needs to reach us in emergency situations knows how.
