Battery health New MacBook Pro

[Mac Hammer Fan]

I bought a new MacBook Pro 15 inch Mid 2015 and downloaded the application Battery Health. According to the manual I can work 9 hours with my battery. But the application says 5 hours remaining. System info says that the battery is in good condition. Should I be worried? Or are the values from the application not reliable?

All software indications of battery life or remaining battery charge are GUESTIMATES.
stop taking them seriously.

No. Don't worry. It takes several battery charges/discharges for those various software programs to hone in on decent estimates. I just bought a new 2015 15"er as well and Coconut battery has been all over the place, but it's getting better now.
