The Technology Behind It
The 13-inch model packs a 52.6Wh battery, while the 15-inch includes 66.5Wh capacity. The M3's efficiency cores intelligently manage background processes, delivering exceptional power management without sacrificing performance.
Maximizing Your Battery Life
Quick optimizations:
