If you want to do your own benchmark, I recommend using BOINC and supporting a grid computing project, like SETI@home. These basically use 100% of your CPU from the moment you turn the program on until the moment you turn it off. This drains the battery pretty quick. Just be careful to check temperatures to make sure the computer doesn't
Macbook Air 2020 Sidecar Hero (Image credit: Rene Ritchie / iMore) Perhaps the simplest (if theoretically most time-consuming) thing you can do in an attempt to correct battery problems is first run down the battery. Use your MacBook Air until it shuts down because the battery level is so low. After this happens, plug your MacBook Air into power.

However, I've notice recently that battery life performance has been less than it used to be. I pulled up the system report and was a bit surprised to see how much the maximum capacity had degraded.
In short, how many years can I realistically expect my Macbook Air to last? It is a 2017 model, well cared for, and in good condition. I ask this as I am considering the new M2 MBA, but after careful consideration, there is not really any great benefit to me in an upgrade.

MacBook Air M1 battery drain rate? Hello. Is anyone experiencing an unusually huge battery drain? I'm using a 5-month old MacBook Air M1.

Go to the “Energy” tab of Activity Monitor. At the bottom of the Energy screen find “Time on battery” to see how long your Mac laptop has been running on battery power. In the example shown here, my several month old MacBook Pro 15″ model is achieving a little over 3 hours of battery life in my own real world usage before it’s

The MacBook Pro is priced to be a reliable, long-lasting investment, but using it for eight-plus years seems excessive. Yet, here I am holding onto my 2012 MacBook Pro, having snubbed years of
The screen-shots below, from the iStat menu sensor data recording, show how the battery is draining (while still connected to the power supply). The DC input from the power supply is reduced to 2 W (20 V at 0.1 A) and power is (mainly) drawn from the battery. above: Battery charge drops to ~93% while connected to power supply MvMDHB.
