How Long Should a MacBook Pro Battery Really Last?

As an Apple repair technician and self-professed MacBook Pro power user, one of the most frequent questions I get is, "How long should my MacBook Pro‘s battery last?" And the answer I give is—it depends.

With so many variables at play, from your MacBook Pro‘s age and configuration to how you use and maintain it, battery life is never a one-size-fits-all equation. In this deep dive, I‘ll share realistic battery life expectations for various MacBook Pro models, telltale signs that your battery is nearing the end of its lifespan, and five proven tips to maximize your battery‘s charge and overall longevity.

What‘s a "Normal" Battery Life for a MacBook Pro?

Apple rates most current MacBook Pro models for up to 10 hours of "wireless web" use and up to 17 hours of "Apple TV app movie playback." But in my experience, real-world battery life rarely aligns with these best-case benchmarks.

Realistically, with medium-to-heavy workloads and normalized display and energy settings, here‘s the battery performance you can expect from recent MacBook Pro models on a single charge:

Model Battery Life (Hrs) Battery Capacity (Wh) Charge Cycles
13" MacBook Pro (M1, 2020) 15-17 58.2 1000
13" MacBook Pro (Intel, 2020) 9-11 58.0 1000
16" MacBook Pro (2019) 9-11 100 1000
13" MacBook Pro (2019, 2 T3 ports) 9-11 58.0 1000
13" MacBook Pro (2019, 4 T3 ports) 8-10 58.0 1000
15" MacBook Pro (2019) 8-10 83.6 1000

As you can see, battery life can swing considerably based on your MacBook Pro‘s configuration. For example, the M1-powered 13" MacBook Pro delivers remarkably longer battery life compared to the Intel-based model with identical screen size, thanks to the exceptional power efficiency of Apple silicon.

"The battery life on the M1 MacBook Pro 13-inch is simply unbelievable. In our web-browsing battery test, it lasted nearly 18 hours, which is the longest battery life we‘ve ever seen in a Mac laptop." — Tom‘s Guide

However, these estimates assume that your MacBook Pro‘s battery is in optimal condition, with a full charge capacity. As your MacBook Pro ages and its battery undergoes more charge cycles, you‘ll notice a gradual decline in battery life.

5 Pro Tips to Maximize Your MacBook Pro‘s Battery Life

While battery wear is inevitable, how you use and care for your MacBook Pro can significantly impact its battery health and lifespan. Practice these five tips consistently to get the most juice out of every charge cycle:

1. Monitor Battery Cycle Count and Health

Your MacBook Pro‘s battery capacity is designed to retain up to 80% of its original charge capacity after completing the recharge cycle limit (1000 cycles for current models). You can check your battery‘s cycle count and condition by following these steps:

  1. Hold the Option key and click on the Apple menu. Choose "System Information."
  2. Under the "Hardware" section in the sidebar, select "Power."
  3. Look for the "Battery Information" header and check the "Cycle Count" and "Condition" entries.

If your battery‘s cycle count exceeds the recommended limit or its condition is listed as "Service Battery" or "Replace Soon," it‘s an indicator that it may be time for a battery replacement to restore performance.

2. Optimize Your Display & Energy Settings

Your MacBook Pro‘s gorgeous Retina display is its biggest power draw. To significantly extend battery life, dial down the brightness to 50% or lower when running on battery power. You can quickly adjust brightness using the F1 and F2 keys on your keyboard.

Additionally, go to "System Preferences" > "Battery" and enable "Slightly dim the display while on battery power" to automatically lower brightness when unplugged.

MacBook Pro battery preferences

While you‘re in the Battery preferences, consider these additional energy-saving tweaks:

  • Set your MacBook Pro to sleep after a shorter period of inactivity, like 1-2 minutes.
  • Enable "Put hard disks to sleep when possible" to reduce power usage.
  • Turn on automatic graphics switching to use the more efficient integrated graphics when unplugged.

3. Limit Background Processes and Quit Idle Apps

Have you ever checked the battery status menu and noticed certain apps or processes using "significant energy"? Spotlight indexing, iCloud syncing, photo analysis, and other background tasks can sneakily siphon your battery life even when you‘re not actively using your MacBook Pro.

Apps using significant energy

To optimize battery life, limit these background processes when you‘re running on battery power:

  • Pause Time Machine backups and syncing services like iCloud, Dropbox, and Google Drive.
  • Quit apps you‘re no longer using instead of leaving them running in the background. On the latest MacOS versions, you can enable automatic quitting of unused apps by going to Battery preferences and enabling "Optimized battery charging."
  • Disable unnecessary push notifications and location services for apps.

4. Keep Your MacBook Pro Cool and Up-to-Date

According to Battery University, a leading authority on battery technology, "Heat is the worst enemy of the battery." Exposure to extreme heat can cause your MacBook Pro‘s battery to degrade faster and lose charge capacity prematurely.

To prolong your battery‘s lifespan, avoid using or storing your MacBook Pro in hot environments, like inside a parked car on a sunny day. When in use, ensure the air vents are unobstructed and consider using a laptop cooling stand to improve airflow.

Additionally, keep your MacBook Pro‘s system software and apps updated to the latest versions. MacOS updates often include energy-saving improvements and optimizations that can help squeeze more life out of your battery.

In a support document, Apple states, "Always make sure your MacBook Pro is using the latest version of macOS. If you rarely charge up your MacBook Pro all the way, it‘s time to perform an update."

5. Recalibrate and Restore Battery Health

If you‘re experiencing sudden shutdowns, inaccurate battery percentage readings, or significantly reduced runtime after updating your MacBook Pro, your battery may need to be recalibrated. Here‘s how to do it:

  1. Charge your MacBook Pro fully and keep it plugged in for at least two more hours.
  2. Unplug your MacBook Pro and use it normally until you get a low battery warning.
  3. Save your work, and keep using your Mac until it goes into sleep mode due to low battery.
  4. Wait at least 5 hours, then charge your MacBook Pro uninterrupted to 100%.

This process recalibrates your battery‘s internal microprocessor and ensures that your MacBook Pro‘s battery percentage readings are accurate.

If recalibrating doesn‘t restore your battery life to expected levels and your MacBook Pro is no longer covered under warranty, consider getting the battery replaced. In my experience, a professional battery replacement can breathe new life into an aging MacBook Pro and greatly improve day-to-day performance.

"If your MacBook Pro‘s battery holds less than 80 percent of its original capacity and is not covered under warranty, Apple offers a battery service." — Apple Support
