Why is Apple so controlling? Why do they have phones that are all nearly identical? Why do they have particular restrictions on background apps? It all comes down to battery life. Battery life is not just another feature on some specifications checklist. It is the driving philosophy behind every design decision made on the iPhone.
He suspects that Android will only develop more battery life issues, and things are already getting pretty bad.
Again, it’s all about balancing constraints. If you want to run seventeen apps at once, or play flash games, you have to expect you’ll get a couple hours out of your phone, max. Apple isn’t willing to create a device where consumers need to be charging their phones five times a day.
