New MacBook only getting 5 hours of battery life

I agree with you on some things, but on others I have to defend Apple. Your claim that the MacBook should have been advertised for five hours of battery life matches my few months' of experience with the new computer. However, I had a MacBook Pro 15” Retina from Late 2013, and it was getting 9.5 hours of battery life earlier this year, so your experience with that computer is not the experience with all of them.

I had a particular case that was able to defend my point. I had just gotten the 2015 MacBook after selling my Late 2013 MacBook Pro 15” with Retina Display. Both computers were advertised for 9 hours of battery life, and I was using them the same way. The only difference was I got 9.5 hours on my MacBook Pro and was getting 5 on my MacBook. Obviously, there was something wrong with my laptop.

I advise you to skip AppleCare’s first line of defense and ask to speak with an AppleCare Senior Specialist. My first interaction with AppleCare was fruitless, but when I asked to speak to a Senior Specialist, things began moving forward.

All,

I have been suffering from poor macbook 12" battery life and have been doing some testing and querying with vendors. My issue was found to be with Outlook 2016 and languages. If you are using Outlook 2016 on your macbook make sure that you do the following:

Click on new email, Options menu, choose language, disable Detect Language Automatically.

I was getting 4 hours, and am now getting between 7 and 9 on a daily basis.

Have you tried to run Activity Monitor to find out which application used up the energy? You can start Activity Monitor from Finder | Applications | Utilities or App Launcher.

I have the same problem. The 15 inch macbook I own is brand new with a new install of software and I had it charged all day. I come home and work for 2-3 hours on wordpress connected through Wifi and it is already down to 47%. I am truly upset with the poor performance of this VERY expensive piece of equipment...
