Battery case is reducing my phones max capacity

HankHowdy said:

Something strange happens when I use a battery case to charge my phone. My max capacity for my battery is around 1418.

When I start using a battery case for a couple charge cycles it starts to reduce the max capacity to 1350's.

What the heck is going on? Are battery cases bad for the phones battery? Is wall charging the only good way to charge your phone?

Thanks.

Which battery case do you use?

How do you know the capacity? Also battery cases add a thick layer of material to the iPhone making it keep in heat for a longer time as the battery case heats up. Like the battery is converting power and charging the iPhone and while the iPhone is charging the battery in iPhone is warming up. The battery case is insulating the iPhone and keeping the device warm. Heat and battery's do not mix.

Guessing it is this battery case:

This is the one I use. I have an app that tells me the batteries capacity. When I switch back to the oem cube then my capacity returns to normal.

You cable instead of cube?

The oem charger that apple supplies for its iPhones resemble a white cube.

I'm very confused on why that's happening. I though it was heat what but it is not.

HankHowdy said:

I noticed that this case isn't MRI Apple approved.

Perhaps it doesn't charge correctly. I know that Li-ion needs to have proper voltage to know when to stop charging.

That could be. I though lenmar is apple approved.

HankHowdy said:

If you take a look at the link, it's not mentioned anywhere, but the link you supplied mentions it.

Counterfeit merchandise I suppose. Maybe buy a new one that is apple approved and if it is better keep it and possibly return the lenmar. If the one below does not change anything you can always return it.
I recommend this one:
