I've always heard that a cellphone battery has a set number of charges, and whether you charge from 0% to 100% or from 75% to 100% or from 55% to 75% each of this instances will use one of those finite charges. So my questions is as follows:
If the above is true and I'm using a wireless charging plate to charge my phone. Say the phone charges from 15% to 30% and I get a phone call. I pick up the phone to use it, thus removing it from the charger. I put it back down after I'm done and it resumes charging. Does that use 2 of my finite charges since it stopped charging and then resumed? If so, wireless charging loses essentially all of it's appeal to me.
Any thoughts on this?

Also don't worry about plugging in your phone early evening and not unplugging it until late morning the next day. Your device has safeguards in place to prevent the battery from being "overcharged". The reason people used to remove batteries from laptops they always had plugged in, was heat. We don't have to worry about that. Our phones are too smart for that to be an issue.

How to Prolong Lithium-based Batteries - Battery University
"Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while."
