Since 2005, Coconut Battery has been my go-to utility for monitoring laptop battery health – it also does the same for iPhones and iPads!
It will show you the age of your devices and their batteries, the battery health, any history you have saved, cycle counts, temperature and so much more…
Overall, a very useful and recommended little utility.
