I was getting GREAT Battery on Cush, better than any ROM.
But today, I was in the car using GPS and had what I think was a soft reboot. I looked back down at the phone and it was at the lockscreen instead of Google Maps and when I opened the lockscreen, all my widgets and app drawer were reloading, but I did not technically see the boot animation.
Since I use GPS a lot for work and stuff it can be really annoying to not have Google Maps working all the time. I like to set the GPS and forget it since it really isn't safe to be opening apps, typing in addresses etc while I'm trying to drive around in the city so then I have to pull over etc. Anyone who drives in the city/highway knows pulling over and getting back on can be a royal pain in the ass.
Thats my only hangup with this ROM. Otherwise, its friggen awesome.
