Have you checked online whether the battery problems was caused by software or hardware. See if these tips from HTC official site works. http://www.htc.com/us/support/htc-one-mini-att/howto/399985.html Well, I myself don't like extended battery that much cos'z the matched case is not so good-looking even it makes the battery lasts longer. Anyway, it's feasible to change a more powerful battery if you need.
