MacBook Pro 15' mid-2015 battery life?

[jaynaytion]

I've just got the new 15" Pro w/dgpu and the battery doesn't seem to be living up to it's billing? On boot with no apps open it says I've got 3.5hrs. Shouldn't it be more like 9...?

Also having a problem with my magic mouse randomly disconnecting every 45 mins or so (this happened occasionally on my macbook air with the same mouse but this is way more frequently).

It depends how you use it. My battery last longer if I dim the brightness of the screen,don't play video or gaming. If I use for typing or web browsing my battery do last more than 5 hours.

Well if you've just got it and loaded it up with old stuff then it'll be spotlight indexing that will cane the battery until it's finished and it can take hours.

If you haven't done so please read the information on the link below it is a very in depth thread on apple batteries and should answer all your questions.

The reading may be improper, try using it with normal usage after it has been fully charged and report what happens.

Also having a problem with my magic mouse randomly disconnecting every 45 mins or so (this happened occasionally on my macbook air with the same mouse but this is way more frequently).

If the problem persisted on more than one notebook, then it is more than likely an issue with the mouse itself. There could be an issue with the bluetooth interface within the mouse that allows it to connect. Just to be sure, try using another bluetooth device with your Mac and see if there are issues with it.

Hope this helps.
