Can devoted tinkerers do the replacement themselves? It depends on whom you ask. While researching Thursday’s article about ways to improve the battery life of portable devices, I got two different answers from two companies I interviewed that sell iPhone replacement parts and services.
According to ifixit.com, a company that provides parts for Mac computers, iPods and iPhones, the answer is yes. For about $32, it will sell you a new battery, plus the tools you need to crack the case and separate the various screws and connectors to get at the dead battery. The battery is guaranteed for six months.
