Keep in mind, when I say 'short bursts', I mean on the time scale of seconds. No capacitor bank is going to be capable of supplying current for that long; especially not one put in a phone. In most cases, the restriction is inevitably heat based (how long can I run this before thermals cause me to need to throttle) and the power supply is pushed to be able to handle it.

EV batteries and e-bikes are a whole different animal than what is used in cell phone battery tech.

Also, is 2.0V bad for the battery? It's not great, but it's not Voc of 2.0V. It's Vsc, essentially. Which is a very different quantity.
