I purchased this phone from a dealer less than a month ago and this was a demo phone(warranty was over and demo phones don't increase cycle counts if they are in official apple stores) so i saw a fair price and took it as it was having 100% health and very less cycle count (34) but i've noticed the pattern that after every 5 cycle count 1% drops now at 94%, and that concerned me so i took the phone back to the dealer he says he doesn't know what's going on and he can't take it back as it dropped 6%, i also checked with 3utools but it showed everything was good no boost nothing. so now i'm stuck with this... i just want to know what can be done.
