A "better battery" would have been a larger battery, which makes the phone bulkier. This isn't a good or bad choice, it's a tradeoff between form factor and battery life. This is a good choice for customers that want bulkier phones with longer battery life. But it would be a bad choice for customers that want a slim phone.
