I used the original Battery Health and liked it a lot. This does the same job, and does it just as well and is much better-looking. But version 2 is missing the "time remaining" estimate section, and the menu bar lightning bolt icon option is gone, meaning that it takes up more room on my toolbar. Also, where the previous version had a usage graph for the last few hours (I don't mean the full history that comes with the add-on) Battery Health 2 is missing it. Bring back the features from the original Battery Health and I put the fifth star back.

MacOS keeps meticulous track of statistics and performance for a MacBook’s battery. Exposing that information would seem like an easy decision: if you know your battery’s been recharged a thousand times and is barely holding any power compared to when it was new, you’ll want to have Apple replace it. Yet, MacOS does not do this.Battery Health 2 does. The interface takes up no more room in the menu bar than the stock battery level report. When you open it, however, everything you’d want to know about your battery is right there. This is a very nice balance of graphics and text, easy to understand, and will tell you what you need to know. Recommended!

My Macbook pro is several years old and was having some issues including possible bttery overheating issues. This app let me see what was expected new and where it is now. Basically the battery is operating at only 66% of its original design use. Or in otherwords it is slowly dying. The battery showed as 5.7 years old, which is about right. It also showed it had during that time 96 full cycles. It also indicated the battery needed to be checked professonionally or replaced. So it is due for a replacement. This is a useful app and amazing for free. You can buy an upgrade that provides tracking. I will probably consider that after I get this old battery replaced.

I still use the previous version on my 2015 Macbook Pro and in my opinion, it was more useful. This new version on my 2020 Macbook Pro tells me my battery is 10.1 years old! Also, instead of a slim dropdown info tab, the new version puts a larger window down in the middle of the screen taking up much more of the viewing area. Who needs such a large window for just battery info? Also, on the older versipn, you click on the lightning bolt icon to open then click it again and it closes. The new version opens with a battery icon but to close it you have to move your mouse down to the large window in the middle of your screen to close it. Overall, its okay but not great.
