La lansarea MacBook Air 2013, Apple a anuntat ca laptop-urile sale sunt capabile sa obtina pana la 12 ore de autonomie a bateriei pentru utilizare obisnuita, OS X Mountain Lion fiind utilizat pentru teste. Ceea ce spunea Apple atunci nu mai este valabil, deoarece acum Air-urile sale obtin pana la 15 ore de autonomie multumita OS X Mavericks si vorbim despre o crestere de peste 3 ore in ceea ce priveste perioada de utilizare. Pentru teste a fost utilizat un script care combina navigare web pe anumite website-uri si editarea de texte, iar rezulatele au oferit o medie de 15 ore de utilizare pentru noile Mac-uri.
I suspect the aggressiveness of the auto-playing Flash ads that happen to be on specific websites on a particular day may partly explain the huge variability in Mountain Lion’s numbers. Some of the lower-scoring Mountain Lion trials may have also had the bad luck to coincide with energy-intensive periodic jobs—jobs that are prevented from running on Mavericks due to AC power or battery-level restrictions as part of centralized task scheduling. These tests may or may not be representative of how you use your Mac, but regardless, it’s clear that Apple’s efforts have not been in vain. Mavericks really does consume less energy than Mountain Lion when performing the same tasks.
Desi nu sunt la fel de radicale, imbunatatiri exista si in cazul Mac-urilor vechi, un MacBook Pro 2007 obtinand cateva zeci de minute de autonomie in plus dupa instalarea OS X Mavericks. Practic noile tehnologii implementate in OS X Mavericks imbunatatesc atat de mult sistemul de administrare a aplicatiilor care ruleaza in background si administreaza atat de eficient energia, incat in final putem obtine cu pana la 3 ore in plus de utilizare in cazul MacBook Air-urilor si probabil intre 1 si 2 ore suplimentare pe MacBook Pro-uri.
