I recently bought a Thinkpad to try if another platform would work. I first ran Windows 10 and found it unworkable and then installed Ubuntu, did some battery tweaking. It is great; have not touched my Mac since. Especially long battery life, swappable batteries and, for my taste, a better keyboard next to more ports is just better over all for my (full stack) dev.
How did you get great battery life from Ubuntu? I've never been able to get anything close to the runtime I get on OSX. In my experience, OSX gives me the longest batter life, second is Windows and any flavor of Linux is terrible (maybe 3-4 hours on a machine that Windows gives 5-6 hours).
I get 16 hours under my Lenovo with ubuntu with tlp default settings. I have to be careful a bit with browsers (they use most in my workflow) but usually I just use lynx for programming searches. OS X on my MBP is ghastly: Apple replaced the battery and I use the same software as under Ubuntu but I struggle to get 3 hrs. On my Air it was wonderful. Windows I have not used for anything serious in 20 years.
