Battery issues on new Macbook Retina 15" Mid-2015 only lasts <3 hours

I am seeing the same issues, on my 2nd MBP as well. The MBP I have now, I have been using Chrome only and the battery won't hold a charge. No additional software has been installed, with this one, I noticed the battery issue right away, and haven't bothered to install any software or transfer my files. does anyone have any answers?

Hi Stazi:

I found this link: http://www.omgchrome.com/new-macbook-dont-use-google-chrome/

It basically says that using Chrome instead of Safari reduces battery life by 3 or 4 hours.

Just as a test, why not try switching to Safari and let us know how you make out.

this would not explain why the battery drains overnight, with no application or web browsers on. Battery went from 81% to 48% overnight. It was left on my desk at work. not connected to anything which could have drained power

Yes that seems a large change with nothing running.

Another thought. Is it possible your Mac is not sleeping properly. That may cause it to use up battery power.

See the following:My iMac does not sleep after install of El Capitan

it is a brand new mac - picked it up late thursday, did nothing with it over the weekend, brought it to work yesterday and notice the battery had drained over the weekend, with no apps on. I charged it back to 100%; unplugged it and watched the battery drain while checking email via the browsers (both Safari and Chrome)

the Energy saver settings are on the default settings turn display off after 1.5 minutes; put hard disks to sleep whenever possible and slightly dim when on battery power.

Be careful, if your laptop doesn't sleep properly, it will fail your logic board when you keep it in your backpack.

I followed the instructions for the SMC reset and that helped with my mid 2015 MBP i7 2.5Ghz.

Battery was showing less then 2 hours on a full charge, and things weren't working as they should. After the SMC reset (link provided by D.Cohen), things are back to normal and I am showing over 7 hours on a full charge.

Don't listen to the noise about Chrome vs. Safari, this might be relevant under other circumstances, but not at all relevant to this problem.

I think it may have started when I used my girlfriend's MBP 13 adapter accidentally to charge, but I'm not sure. Anyway now I am using Chrome (!!!) and still getting over 7 hours on a FC.
