Just got an ultimate MBA 11" and haven't been thrilled with the battery. 5 hours would have been great but i am seeing closer to 3. how about in this thread we just list : 1. MBA specs 2. typical apps running 3. Battery life what i propose, since we all use them differently, is just charge it up, start using it and note the time. especially note if it is continuous use. As an addendum feel free to add details like what apps were running throughout, other usage patterns that might help give people a better idea of battery life. p.s. another thread is noting that battery life appears to have improved with the new 10.7.1 update. please note if you have seen this.
