While very reliable, it can occasionally have issues that require a reset. The first thing to try is resetting your System Management Controller (SMC), which is a hardware chip that controls some hardware settings, including the power system. I’ll show you how you can attempt to resolve the issue yourself before replacing the battery outright. If you get the Service Battery warning, the cycles are above about 1,000, then your battery’s likely pretty close to worn out.īut if your cycles are relatively low, then there may be other issues at play and you should use the methods I’m about to describe. How Do I Change Low Battery Warning on My MacBook? If you mouse over your battery icon on the status bar at the top of your screen, a popup will display the battery status, the amount of power remaining, and a list of apps that are using a lot of power. Your MacBook monitors the health of its battery. Partial charges do not count as a complete cycle if you discharge your battery a bit and then charge it back up, that will only count as a fraction of a cycle for its internal monitoring. Note that the macOS is quite intelligent when calculating cycles. It will continue to degrade slowly over time and will eventually stop working altogether, but that can take years. Note that even after this long life-cycle (a complete discharge and recharge every day for three years), your battery will still work - it just won’t have the same ability to hold a charge as it did at its peak.
