Battery down to 67% in 1hr 6 it time to upgrade?

Late 2013 Macbook Pro. I'm running Windows so I'm not sure if the OS is just a battery hog or if my battery is about done for but I finally got around to timing it and found I'm down to 67% battery life in just 1 hour and 6 minutes.

Howe good or bad is that for a Macbook Pro or any laptop for that matter? It's been so gradual that I honestly do not remember how long I used to be able to use this laptop for before losing half the battery power but I never measured it. It's only in recent months this year that it seemed like I have to plug it in more often.

Also another question. How many years do you guys typically go with a laptop until you upgrade it? Mine is really close to the 5 year mark but the processor (i7) is still plenty powerful enough for me and otherwise works great so not sure how easy it would be to replace the battery, if it can even be replaced.

I've heard, but never experienced directly or measured, that Apple's own OS is a lot more power-efficient than Windows' Power Management is, on similar hardware.

Be careful as the battery replacement might cost enough to be better off buying a new laptop.

do not buy the newest MBP with touchbar!
I have one and damn it suck. The touchbar is so easy to press "esc" without even noticing it and it's just useless. The new MBP are also can't be repaired easily when you are out of the warranty (keyboard is with the logic board - WTF?).

Change the battery and enjoy your MBP.

I also have a 2013 MBP. A charge was good for about 7 hours when it was new. Now it's down to 4-5 hours. But I don't run Windows.

The batteries were glued in by late 2013. You can replace them but it's kind of annoying.

My housemate's 2010 MBP got a new battery 2 years ago. (~5 hours new, ~1 hour when we replaced it.) NewerTech brand, from Other World Computing. After the replacement it was good for ~4 hours, and is now able to chug along for ~2.5 hours. But we've been keeping the OS up to date the whole time, so it's not apples-to-apples. (More background tasks, etc.) The old C2D definitely runs hotter than it did new, so it's probably using energy to run the fan more.
