This is just another example of consumer hostile planned obsolescence. Rechargeable batteries are consumables. Most cell phones used to have removable batteries so when it wouldn't hold a charge any more you could easily replace. Now most phones have integrated batteries which can only be replaced with an expensive and inconvenient visit to a repair center.

You're niche. Most people don't care as long as their phone is fast and they can use their phone all day. By the time a phone's battery becomes unusably short (my iPhone 4s still holds a charge for about a full day), most people agree their phone is ready for replacement.
