![]() ![]() Press Shift+Ctrl+Option+Power at the same time and hold.The process is straightforward, but any customizations to your power plans or hardware settings may also be reset. 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? Modern Macs get at least 1,000 cycles before there’s a problem, though if you have a Macbook that’s older than 2010, then you may only have 500 cycles available before your battery’s worn out. Look at the Condition of your battery (indicated directly below Cycle Count), which should be Normal if your battery’s operating properly.Under Battery Information on the right-hand side, look for the Cycle Count under Health Information.Select the About this Mac in the Apple Menu.Select Power on the left side and review your battery health.Īnother way to view the System Report is by doing this:.Click the Apple icon while holding the Option key.To access the details about your battery, do this: You can check the health of your Macbook’s battery by using the System Information function. The first thing you should do when you get a ‘Service Battery’ notification is to check the ‘System Report.’ This will tell you the cycle count and overall condition of your MacBook battery. Service Battery: There is something wrong with your battery, and it needs to be replaced as soon as possible.It’s time to start looking for a new battery. Replace Now: The battery still works but has degraded significantly.Replace Soon: The battery is holding less of a charge than it did when it was new but is still working fine.Normal: Your battery is operating within normal parameters.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 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. How long can you expect that level of performance from your battery?Īpple states that its new batteries are designed to support 1,000 full charge-discharge cycles, after which the battery should still have 80% or more of its original capacity.

MacBook Battery LifeĪ typical MacBook or MacBook Pro can run for about 10 hours when using the Internet and doing normal computing tasks like word processing or playing music. How many times can the battery be discharged and then recharged before it no longer functions at full capacity?įor lithium-ion batteries, the number of cycles before this varies widely depending on the quality of the battery build and the level of discharge that the battery supports. The main factor we are looking at today is the charging life cycle of the battery. Of course, knowing the dangers of a swollen battery are important to your safety and electronic devices. As battery technology has developed, this problem has been more or less eliminated by the addition of electronic monitoring circuitry added to a battery. Those stories are true this type of battery is subject to overheating and exploding if they are not carefully monitored. You have undoubtedly heard news stories about lithium batteries exploding or catching fire. ![]() The results will go on your permanent record. ![]()
