Questions & Answers for iPhone 11 Pro Max Smart Battery Case - Black

It is 'Smart' :)
It works as you'd expect and desire:
When fully charged, the battery case depletes first, then the iPhone. So if at any time you took the case off, the Phone would still be fully charged, if possible.
When placed on charge via a Qi mat or Lightning, all power first charges the iPhone, then charges the battery case. As you would want.
Unlike 3rd party external USB chargers, iPhone knows it's not _really_ on charge - it knows it's not on a wall charger in other words. The phone still acts like it's on battery power. That means the phone won't drain your batteries by analysing the contents of your photo library, doing large iCloud syncs, and other things which only happen when on the charger. This means the Smart Battery Case actually lasts a lot longer in use than it's mAh rating would suggest - because the phone treats it like a battery, not a charge.
I hope this makes sense. :)

It is not possible for the case to damage the battery like this. The OS and the battery case/battery work in tandem to prevent this from happening.

The case weighed 3.88 ounces (110.1) grams on my scale.

The iPhone 11 Pro Max is said to weigh 7.97 ounces (226 grams), but it weighed 7.88 ounces (223.4 grams) on the same scale I used to weigh the case.

Adding the case makes the phone about 50% heavier than it is without a case.

Yes it will, that is why the top is clear of battery cells as the NFC chip is in the top of the phone

The case has an integrated Lightning jack that connects to the Lightning port of your iPhone. You can place the iPhone while in the case to a wireless charger and charge your iPhone and case wirelessly.
