I'm digging my Thinkpad T570. This bad-boy has two batteries!

2 batteries? How did I miss this one? What kind of realworld battery life are you seeing?

The Thinkpad T4x0 series has two batteries as well. I had a T450s at my previous job and I think I'd get 6-7 hours out of it (usual workload of ssh, vim, 50-100 chrome tabs, slack, google play music all running).

The T470 (not the T470s) also allows you to hotswap out one of its batteries too, so you could carry an extra if you needed it: http://www.notebookreview.com/feature/business-laptop-battle...

Just chiming in with another recommendation for the T470, which I currently own. It has a pretty decent battery life.

I wrote about my experiences with installing Linux on it here: https://medium.com/@debugjois/installing-ubuntu-gnome-17-04-... (it’s a bit outdated. I run Arch on it now)

You have a few issues listed in that blog post. Do any of them sill plague your system, or has Arch sorted them all out?

Most of the issues were sorted out by kernel updates, and a BIOS update I performed recently.

The only thing that Arch clearly improved was the Bluetooth experience, which was very unstable on Ubuntu (even after the upgrage to 17.10). But even that is probably down to the newer kernel in Arch.

You can do better! I get near 20h some times longer with about the same work loads. Make sure you have tlp and use the settings suggested by power top. There are also a few options to pass to the i915 module that increase power savings.
