We all want Mac laptops that can run for days on a single charge and never need their batteries serviced. Sadly, we’re always going to be disappointed. Battery and power management technologies continually improve, but those improvements are matched by more powerful processors and smaller designs with less room for battery cells. And, because physics is a harsh mistress, current lithium-ion batteries are always going to age chemically, so they hold less of a charge over time.
In the just-released macOS 10.15.5 Catalina, Apple has introduced a new battery health management feature that promises to increase the effective lifespan of the batteries in recent Mac laptops. It does this by monitoring the battery’s temperature and charging patterns and, in all likelihood, reducing the maximum level to which it will charge the battery.
You see the problem. While battery health management can extend your battery’s overall lifespan, it will likely also reduce your everyday runtime before you need to charge. It’s too soon to know the full extent of this tradeoff, and we suspect that it may be impossible to determine, given that everyone uses their Macs differently.
It’s worth noting that this battery health management feature appears only for those running macOS 10.15.5 or later, and only then if the Mac in question is a laptop with Thunderbolt 3 ports. In essence, then, it’s available only on MacBook Pro models introduced in 2016 or later, and MacBook Air models introduced in 2018 and later. (The Thunderbolt 3 port requirement is merely a shorthand way for Apple to indicate “recent Mac laptops.”)
So, if you have a supported laptop and you’re running macOS 10.15.5, what should you do? We see three scenarios:
- Favor lifespan: If you seldom run your laptop’s battery down to the electronic fumes because it’s easy for you to plug in whenever you need to charge, leave battery health management enabled. That will preserve the battery’s overall lifespan to the extent possible.
- Favor runtime: For those who need to eke every last bit of power from their batteries, disable battery health management. You might have to replace the battery sooner, but you’ll get more runtime in everyday usage.
- Switch as needed: Many people need the longest possible runtime only occasionally, such as on long flights with no under-seat power. In such situations, switch battery health management off for the flight and back on when you return to normal usage patterns.
Switching is easy, but Apple buries it deeply enough that it’s clear that the company doesn’t think most users should be disabling it regularly. Open System Preferences > Energy Saver, click the Battery Health button at the bottom, and in the dialog that appears, uncheck Battery Health Management and click OK. You’ll be prompted to make sure you know what you’re doing; click Turn Off to finish the job.
One final note. The reduced maximum capacity with battery health management enabled may have an undesirable side effect—a recommendation from the Battery Status menu’s health indicator that you need to replace your battery. To check your battery’s health, hold the Option key down and click the Battery Status icon on the menu bar. At the top of the menu, next to Condition, you’ll see either Normal or Service Recommended. (In previous versions of macOS, it could have said Replace Soon, Replace Now, or Service Battery.)
Regardless of the term, anything but Normal indicates that your battery is holding less of a charge than when it was new. If you see that message and you aren’t getting enough runtime for your needs, get the battery evaluated at an Apple-authorized service provider or Apple Store.
Social Media: If you have a Mac laptop with Thunderbolt 3 ports, the new battery health management option in macOS 10.15.5 Catalina could extend the lifespan of your battery. However, it comes at the cost of reduced everyday runtime. Learn more here:
Need help with something? On occasion, we all need tech support. Speaking as the people who are sometimes on the other end of those requests for help, we have some suggestions on how to get the support you need as quickly as possible.
For instance, think about what we have to do if we receive an email message along the lines of “I keep getting a note that my backups aren’t working.” All we can tell from that message is that something may be wrong with the user’s backups. But without knowing what app they’re using and what the specific error is, we can’t even begin to recommend a solution. We’ll have to go back and forth to figure out what we need to learn to address the problem. By the end of the (possibly lengthy) process, the user and we may be quite frustrated.
So here’s a simple set of steps you can use to get to the heart of a troubleshooting problem whenever you’re communicating with tech support.
- Describe your setup as it relates to the problem. Whenever possible, be specific about what apps you’re using and include screenshots or videos. In our example above, this might involve saying, “I back up with Time Machine to an external hard drive. It has been working fine, but now I’m getting this error.” (Obviously, if you’re talking on the phone, it might not be possible to share a screenshot, but you can read it to the support rep.)
- Next, explain how you’ve tried to resolve the problem so tech support doesn’t automatically tell you to repeat the same actions. (They may anyway, just to confirm that you did everything properly, but it’s still a help.) You might say, “I clicked OK and let Time Machine try again, but I got the error on the next backup too. Then I launched Disk Utility, selected my Time Machine drive, and clicked First Aid.”
- Finally, explain what happened (or failed to happen) when you took the actions in the previous step. For instance, “First Aid also reported an error.”
- At this point, you may need to repeat Step 2 and 3 for each thing you tried, but you’ve given the support person enough for them to start recommending other courses of action. (In this case, we’d have you erase the drive using Disk Utility and see if that eliminated the error. Even if it did, we’d recommend that you get a new backup drive since you don’t want to depend on a potentially flaky drive for important backup data.)
The steps are a little different if you’re trying and failing to figure out how to accomplish some task. Try this script:
- I want to _____. State what you’re trying to achieve, and as before, make sure to say what apps you’re using. For instance, “I’m using Preview to read a PDF, and I want to print it with four pages per sheet of paper to avoid wasting hundreds of pieces of paper.”
- I tried ____. As before, explain what you’ve already attempted, as in: “In Preview’s Print dialog, I tried choosing 4 from the Copies Per Page menu.”
- What happened was _____. Finally, explain what happened after what you tried, and why it was wrong. “That caused me to get four copies of the same page in the preview, rather than four different pages.”
- Again, you may need to repeat Steps 2 and 3 for everything you tried, but in this case, we have all we need to explain that you need to click the Preview menu in the middle of the Print dialog, choose Layout, and then choose 4 from the Pages Per Sheet menu.
One last thing. It’s always important to explain your overall goal, rather than just ask a specific question. In the example above, for instance, saying that your goal was to reduce paper usage was helpful because we could then suggest that you select the Two-Sided checkbox near the top to print on both sides of the paper, cutting your paper usage in half.
So next time you need to contact tech support, make sure to use these tips, and you’ll likely get better support and a faster resolution to your problem.
