Hello all,
So, here goes- my very first post on MacRumours.
This is going to be a bit long so pls bear with me.....I have been having the following annoying problem with my Mac:
I am using a mid 2011 Macbook Air 13. I fresh installed Sierra and found that I was only getting a maximum of two hours of battery life from a full charge. It was getting through 1% every 40 seconds!!!
After reading around on the net, I decided I would fresh install El Capitan. I did so, and instantly things improved. The Mac said I would get over 5hrs on a full charge.
Then I went to the app store and downloaded a software update. It installed and the Mac restarted, but after I logged into my account, the battery was only estimated just over an hour on a full charge. What??????
I proceeded to (via recovery) reinstall OSX. Not a fresh install, though. Battery life has now improved (note that I have not installed the software update) but I am still not getting Apple's promised 7hrs web browsing.
Have tried SMC and PRAM/NVRAM reset many times...in vain. Activity Monitor holds no answers and all apps are behaving normally when it comes to energy impact.
The battery has done 550 cycles, but that is only just over half way to the promised 1000 cycles before it starts to gold way less charge, so surely one percent every minute or less is not right???
Does anyone have any further ideas about how I can get some decent battery life oh this Mac? I use it for travel and keeping in contact with family when away, and I am always at a desk with my charger whilst using what is supposed to be Apple's most portable Mac.
Thanks in advance for any help/advice everyone.....
Alex
