> Generally, as long as you keep the phone plugged in, the battery should be safe virtually indefinitely

What is your source on this?

I've replaced the battery in always-plugged-in iPhone 3 times over 10 years because it was expanding into a spicy pillow.

I too want a way to run phones directly off of USB power, without a battery present.

Go to ifixit.com, look up your phone's battery replacement steps, stop half way through :)

Yeah the first two times Apple did it for me. Then Apple stopped supporting battery replacements on a phone that old, so I ordered a battery replacement kit on Amazon and did it myself, with ifixit.com's assistance.

Never again. I was genuinely shocked the thing turned on once I closed it up. It's one thing to have a conceptual understanding of how tiny the components inside a phone are. It's another thing to actually be trying to seat a plug into a socket with tweezers and just have no idea how you're supposed to tell if it's fully inserted or not.

		I agree. But for removing batteries, could not be easier. The ifixit guides are especially good because they warn you of the stuff you could never anticipate when opening glued on cases.
