    First time on a laptop and confused by the MacBook Pro 10 hour battery claim. I've read some reviews stating that they're not getting close to the 10 hour mark but I'm really falling well short of it. I feel like at best I may get 5 hours, maybe 4 on my MacBook primarily using iTunes and Safari. Three hours ago I closed the screen with the power still on at 31%. Opening it back up and waking the screen I'm now at 23%. Is this normal?

    First week or so the battery life will be shorter. After that is should stop indexing and get better.

    If the battery drained from 31 to 28 with the lid closed, this indicates to me that a program or service is preventing the MacBook from entering deep sleep.

    I'm definitely dropping approx 20-30% per hour. Most of my usage comes from iTunes and Safari. Seems odd.

    Since moving to Mojave my battery consumption is far worse especially in sleep. I tend to lose 10% in 6 hours.

    I just made some change and now it might be a loss of perhaps 6% in 6 hours, which is not as bad but still pretty poor. Way worse than Sierra.

    All that aside, open Activity Monitor and you can check which apps are draining your battery. You can also determine whether those apps are preventing sleep. I would start there and see if that provides any clues.
