Power supplies are glued into iPads: didn't you know?

nospam
no they aren't. where did you get that insane idea? plus, what's in

that picture is not an ipad power supply anyway nor is there any

evidence of it being glued to an ipad.

the batteries inside an ipad, however, are glued (and not in all of them) for many reasons.

battery != power supply.

Isn't it?

nospam

Why isn;t it. The battery is the power supply it's what supplies power to the circuitry so it is the power supply.

the power supply refers to the part that plugs in the wall, not the battery.

Apple doesn't refer to them as a "power supply". Apple calls them a "Power Adapter". It adapts, or converts, the incoming power to the level that is required to charge the battery.

If you Google "iPhone power supply", you are redirected to "charging devices" and "power adapters".

I would not consider an adapter to be a power supply. The power adapter charges the battery, and the power the phone uses comes from the battery.

The phone can be used with the adapter in use, or with a charger connected to a 12V system, but the power still comes through the battery. Without the battery in place, there is no way to power up the phone without some modification to the phone.

In any battery-powered device - like a drill or a portable vacuum - no one would consider the adapter used to charge the battery to be a power supply. It's called either a power adapter or a charging device.
