Fast ChargeĬertain Apple devices-most notably the iPhone 8 and later, USB-C iPad models, and 14-inch and 16-inch MacBook Pro models-support fast charge, which can boost the battery up to 50% in 30 minutes.įast charge requires a sufficiently powerful charger and appropriate cable-it does not work with wireless MagSafe and Qi chargers. In an effort to meet both of these conflicting desires, Apple has developed two seemingly contradictory technologies: fast charge, which does what it says, and Optimized Battery Charging, which actually makes the battery charge more slowly. Long-term, they want the battery to maintain its capacity for as long as possible-replacing a battery to bring a device back to decent daily battery life is expensive and annoying. In the short term, they want the device always charged and ready to use-little is more frustrating than running out of power earlier than you’d expect in a day. Users have two conflicting desires with regard to batteries, whether or not they realize it. Holding the battery at a 100% charge level.It’s more forgiving than older technologies like nickel-cadmium, but it’s all too easy to shorten a lithium-ion battery’s lifespan by: The inherent problem is that lithium-ion-the current battery chemistry of choice-isn’t particularly stable. Engineers keep finding ways to cram more transistors into chips, but batteries have hit a brick wall of physics, forcing hardware makers like Apple to invent creative workarounds for those limitations. The most significant limitation for mobile devices is power.
