I have updated to 10.7.1 few days ago. Test it and I didn’t notice any different to 10.7.0. May be after I have done the SMC and the maunal graphic card switching which have already resolved my short battery life issue. I did a search on google about what is updated in 10.7.1 and I found that the problem it listed I didn’t notice any of them while I am using that on my MBP.
The main concerns for other people still the battery issues on OS x Lion. However, there is no word about battery life improvement on the 10.7.1 and some people have also confirmed that 10.7.1 make no changes to battery life.
Look like only a few people are lucky enough like myself who can fix their battery life issue with SMC reset and the maunal graphic card switch trick.
Come on Apple, can you confirm your OS works properly before releasing them?
I have a Mac Book Pro early 2011 version running on a 2.2 quad core i7, before I upgraded to Lion, when I fully charged the battery indicator always display 5+ hours of battery life. However, as soon as I have upgraded to Lion, even I have fully charged my Mac Book Pro, the battery life indicator has never display anything over 4 hours.
I then go to change some energy saving setting, adjust the brightness, etc and finally can squeeze the battery timer up to 4:30. However, I still can see a significant shorten life of the battery.
In summary, in my personal experience of this Lion upgrade (+ some other articles online), I am quite certain that the current Mac OS X Lion (10.7) is using a lot more power than it previous OS (10.6.8). Now I am hoping Apple will release a 10.7.1 to get this power consumption issue fixed.
After my extensive testing on my Mac Book Pro, the battery life is shorten around 1 – 2 hours in normal use.
