my battery life has got worse..i tried it out for a couple of days just to be sure. i have everything set up like it was before the update & its consistently getting less than pre-2.1.
i was running live wallpapers for the first couple days & with light use, by bed time the battery was at 40% or less.
then i changed to regular wallpapers for two days, same.
before 2.1, with my usage, at bedtime it never got below 50%
but hey, f=it, i have a car charger if i need it LOL
