Resolved Apple battery case : question

[gren_patterson]

I was thinking to replace my iPhone6 (battery life)
But then I thought 'why not a battery case and wait for the 8'

My question,
While charging the battery heats up.
Will it also be in a apple battery case, plus in this case it charging all the time...

So, what about the heat??

When your phone is in a battery case, you're not charging your phone battery any faster than you're using it. So no, it would not cause any significant heating.

Actually, I suspect it's more like draining the battery case's battery first, rather than charging your phone's battery, but I haven't tested this as I find current incarnation of battery cases overly large and clumsy.

If only Apple had put their "smart" connector on iPhones, then a battery case could connect to it, instead of having to daisy-chain onto the lightning jack, causing the length of an already rather large phone explode further...

I have a battery case on my 6s, there is no significant heat, the case just charges the phone all the time.

Be aware that if you get a case instead of a battery, it's much more bulky and heavy
