Battery drain
Unfortunately there are still critical problems with latest version. I still get around 40% battery use within 24h period. The worst problem for me is that when I turn tracking off for longer time, it continues tracking after awhile. So far the only way to really prevent MileWiz draining 18-40% from my battery is to uninstall it :(. Support is polite and helpful, but I have been having this problem for around 6 months now and the latest update didn't fix the problem.
