I just bought a brand new 13 inch MBP, the top model. It is advertised as lasting 10 hours, but the battery is draining at a much faster pace. I have updated it to 10.13.4. Anyone else having this issue or have suggestions?
 
Download coconut battery and look at the capacity. If that‘s close to 100%, look at the Activity Monitor to see what‘s using your CPU.
 
The 10 hour rating is based on doing specific tasks (like light wifi web browsing). If you're exporting Final Cut Pro X videos then your mileage may vary. What does faster pace mean? What programs are you using and what are you doing with them?

I will try that!

Thats all I’m doing right now, nothing heavy yet. Still setting it up and moving files around and copying stuff to and from the Network. I’d say it’s draining in 2 hours...
 
Use it for longer than a few hours before you complain about battery life

Tips: use safari
Clicking by the battery amount left will show you the apps using energy
Don’t use the screen at full brightness
Heavy photoshop or programs like iMovie will use the battery quickly
 
OK, 10 hours is rarely seen in real world. And yes, I get it when I do Safari browsing and some text editing, when running below 50% display brightness. May be movie watching (MBP2017). But once I do anything more demanding, cpu goes up, battery goes down. It is simple physics, No one can do anything about that...
Also, installing, setting up new computer - installers need to uncompress, Spotlight needs to index the drive, some other tasks need to run. I usually leave computer over night after system upgrade running to finish all indexing, backup to TimeMachine etc. That helps to reduce background load.
 
I have been web surfing and doing some python programming and reading some PDF's, I have used my 13" for about 4-5 hours total today and I am at 44%

You're probably doing more heavyweight tasks. :p

My battery on my 2008 MacBook lasts for a few hours with just standard use. With YouTube videos and Netflix it drains WAY too quickly.

the 15 inch gets better battery life than the 13 inch.

I do use Safari and will check the Apps. Have not even touched Photoshop or iMovieor anything like that yet.'

I pretty much have left it plugged in and turned off or the first two days... I did try and lower the brightness, the screen didn't seem to change.

Have not done any heavyweight tasks yet...
 
the tbMBP 13" is known to have worse battery life than the non-tb and the 15" due to a faster processor, additional fan, but same wattage battery as the non-tb model

Actually TB has smaller battery than non-tb model. And with higher watt CPU/2fans.
 
Look at my signature - there is a link to the battery life statistics for most MacBook models. It says that the 13" MacBook Pro w/ Touch Bar usually runs on battery for about 6 hours.
 
I will try that!

It’s probably spotlight indexing everything you are adding this will impact performance and lower battery life until that spotlight indexing has finished give it a few days to settle down.

where are the battery figures 13 inch vs 15 inch?
 
Spotlight should have a system indexed in a half hour not a few days

It certainly takes longer than half hour and the OP is still moving stuff around using networks etc, it will spotlight index this as it happens and any externals so set up as well.

Yeah but what websites are you visiting? Web ads can eat CPU. Ad blocking can help with that.
