My BH is at 81% so im soon due service but I can play 3-4 games until it gets hot and that spends about 15-20% of battery. but if the battery is new I doubt it would get hot and you could play more
IPhone XS Max is completely fine , 95% BH after a year and 8 months use and just few days ago I tried cleaning the front speakers and ended punching it a little with the hard tooth brush and now it sound a little bit different distorted , not notice able on sound but a bit noticeable on call and every now and then , it keeps making me worried and I just keep thinking of it as a phone with issue to the extent I even called a seller to swap it in for another Xs max again , am I thinking too much or this is normal for everybody
