Put that on a phone and the battery will degrade almost 30% in one year... seems a lot tbh.
As a point of reference, Google says that somewhere between 500-2000 cycles you can expect a regular lithium battery to degrade to 80%. So this is worse, but in the ballpark. Seems reasonable for a research prototype to be a little worse than a commercial product that’s had years to become highly optimized.
But depending on cost, in my hopeful optimistic universe, that could mean bringing back replaceable batteries.
