They should have stated that in the Specifications!

Cheers!

The phone I normally use doesn't need charging.

Cheers!

They state the battery capacity. How that translates into operating time is purely dependent on usage - it’s an estimate, not a specification.

That’s pretty unusual. Very few phones are wired nowadays.

Dont tell me, tell logitech.

That’s exactly what I said.

I'll give you that! I must read more carefully in the future!

I would still prefer something like, "an overnight charge will give three months normal use".

Cheers!

It’s not really a pain. Just keep a usb C cable plugged in to the computer. And connecting a usb C plug is much easier than any variant.

Wired mice went out with the ark. Good riddance.

But not for gamers, by all accounts. I still hear people saying that wireless mice adds latency and they are not reliable.
I presume they are better now. For games on the PC I have an old Logitech G502 Wired mouse, not so much that it is wired, but because it is a conventional mouse. If I use my lift mouse for games, when I press the button in the heat of the moment, I move the mouse as well

I am not a good games player, I just enjoy the ones I play

As I said above, my lift mouse uses a normal battery, stick a battery, and it last for over 6 months if not longer if you remember to turn the mouse off
you can always use a rechargeable battery, but not sure how well that will work, I normally find them only work well on devices that are high drainage

6+ months later ...

I charged my mouse back in January. This morning, the red power light is on!
