160 is the tipping point with Lipolys, you are correct though, they are more efficient when run hotter. I suspect the phone would shut down before anything got too hot to cause damage, because that damage could be deadly, and lead to expensive litigation for HTC. Lipolys are not a battery to mess around with as I alluded to earlier in this thread, and as such I highly doubt HTC (or any other manufacturer for that matter) would have used it without extensive failsafes being used as well.
