I know nothing about working with BETA versions. Just not something which I want to risk with any of my machines or devices. Anyway, tracking the charging thing is not something I've ever tried or even thought about trying...... When I am charging a device, I simply look every now and then...... iI it is something that I really feel a need to track I might look more often but seriously, it is not a big deal to me, especially with my computer(s), which are kept plugged in most of the time anyway. I rarely use my MBPs on battery alone, just once in a while. With the iPhone or an iPad, I may monitor progress of charging if I'm in a hurry to go somewhere and need to get the thing charged up to a reasonable amount before I leave the house with it.....otherwise, it is just not all that important.
