How to Monitor Mac Battery Health?

29.11.2017

Owners of MacBook Air and MacBook Pro should pay close attention to their laptop’s battery health. Keeping track of the notebook battery cycles is crucial for knowing when to replace it. In the event your Mac’s battery rapidly discharges, or your laptop refuses to work without a power source, it’s time to get alerted. Because of multiple recharge cycles, laptop batteries gradually lose their operating capacity. macOS Sierra constantly monitors the battery condition to help users evaluate their laptop’s battery health.

MacBook Battery Condition: What is a Charge Cycle?

The manufacturer sets the limit on Mac’s battery life span. The more intense battery use is, the faster it wears out. Users should monitor the battery status and serviceability, or they risk to end up with a non-working laptop. One charge cycle equals spending all of the battery’s power. However, this doesn’t equal one full battery charge.

Using a half of the charge then completely recharging the battery wouldn’t equal a single charge cycle. In fact, it may take a few days to complete a cycle. For example, if you use 25% of your battery power then charge it to 100% four times, it will equal one battery cycle (25+25+25+25=100).

How to View MacBook Pro or MacBook Air Battery Condition?

To assess your MacBook Pro or MacBook Air battery condition, hold down the Alt (Option) key and click the battery icon in the menu bar. Alternatively, in the Apple menu, go to About This Mac -> System Information, then access the Hardware section in the left pane -> select Power.

In the right pane, you will find Health Information, which includes Cycle Count and Condition.

Compare the cycle count in System Information to the manufacturer’s limits to learn the life expectancy of your laptop’s battery. For instance, the maximum cycle count of MacBook Air computers manufactured between late 2010-2017 equals 1000.

There are four battery condition indicators:

  • Normal means the battery is functioning properly.
  • Replace Soon indicates there is a malfunction, which requires a battery replacement soon. At the same time, the battery may work fine, but keep the charge less than before.
  • Replace Now indicates there is a serious malfunction threatening to damage your laptop. The battery requires replacement to prevent the damage. At the same time, it may function well but keep the charge a lot worse than before.
  • Service Battery means you have to replace the battery immediately. There is a possibility of the battery overheating which may result in damage to other componentry of your MacBook.
