One of the biggest mysteries of the iPhone is how Apple manages to get a full day’s worth of performance from the iPhone when it features a battery that is not rated more than 2400 mAh. When you look at Android devices, you will see smartphones featuring huge 4000 mAh+ batteries in order to deliver that one-day battery life.
The key to Apple’s success is the optimized iOS platform. Apple has designed their mobile OS in such a way, that apps only go full throttle when they are needed. When you have apps running in the background, they either go on a sleep mode sort of activity, or they turn off entirely. This saves on precious battery life, and thus allows iPhones to deliver that stellar battery performance.
