Lp A,m (dB)
Idle2.3 (K V = 0.3)13
Wireless web2.3 (K V = 0.3)13
  1. L W A,m is the mean A-weighted sound power level, rounded to the nearest 0.1 B.
  2. Lp A,m is the mean A-weighted sound pressure level measured at the operator position (rounded to the nearest 1 dB).
  3. 1 B (bel) = 10 dB (decibel)
  4. K v is the statistical adder for computing upper-limit of A-weighted sound power level.
  5. The quantity, L W A,c (formerly called L W Ad) may be computed from the sum of L W A,m and K v.
  6. The Wireless web test browses 25 popular websites.

  1. MacBook Pro with Apple M1 chip: Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip, 8GB of RAM, and 512GB SSD. The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 8 clicks from bottom. The Apple TV app movie playback test measures battery life by playing back HD 1080p content with display brightness set to 8 clicks from bottom. MacBook Pro with Intel Core processor: Testing conducted by Apple in April 2020 using preproduction 1.4GHz quad-core Intel Core i5-based 13-inch MacBook Pro systems with 8GB of RAM and 256GB SSD; and preproduction 2.0GHz quad-core Intel Core i5-based 13-inch MacBook Pro systems with 16GB of RAM and 1TB SSD. The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 12 clicks from bottom or 75%. The Apple TV app movie playback test measures battery life by playing back HD 1080p content with display brightness set to 12 clicks from bottom or 75%. The standby test measures battery life by allowing a system, connected to a wireless network and signed in to an iCloud account, to enter standby mode with Safari and Mail applications launched and all system settings left at default. Battery life varies by use and configuration. See apple.com/batteries for more information.
  2. 1GB = 1 billion bytes and 1TB = 1 trillion bytes; actual formatted capacity less.
  3. Weight varies by configuration and manufacturing process.
  4. iMovie, GarageBand, Pages, Numbers, and Keynote are available on the Mac App Store. Downloading apps requires an Apple ID and a device that is compatible with the OS version required for each app.
