Like you'd know what you're doing

Randall Stross, an author based in Silicon Valley and a professor of business at San Jose State University, has an article in The New York Times about cell phone batteries:

Why is it fairly easy to open some smartphones and tablets, while others seem designed to thwart a user’s effort to repair them, or even replace the battery?
Some devices, like my Android phone, a Galaxy Nexus by Samsung, have a back cover that slides off and a battery that pops out. And when evaluators at iFixit, a website offering do-it-yourself repair manuals and parts, disassembled Google’s new Nexus 7 tablet for a “teardown” review, they found that it was easy to open and repair.
In iFixit’s video review, the narrator describes how the battery can be replaced without unscrewing a single screw. She is moved to declare: “The sustainability-geek inside me wants to hug Google for this.”
Other vendors (Apple, would you please take a bow?) make products that are designed to keep users out. The case on my wife’s iPhone 4 is closed with screws of Apple’s own devising that require a special screwdriver.
IFixit offers a tool kit for replacing those screws with standard ones. It mischievously markets this as a Liberation Kit.
It isn’t surprising that Apple, the epitome of the closed organization and overlord of the iPhone’s tightly controlled software ecosystem, would design screws that, in effect, serve as locks. And one can see how it would be in Apple’s interest to make it hard for users to extend the life of older models; it’s a way to encourage the purchase of the newest, greatest Apple stuff.
Google, which until now has not done much in consumer electronics hardware with its own brand name, is positioning itself as a conspicuous alternative to Apple, in design as in other aspects. As long as Apple embraces closed systems— and closed cases— Google can take advantage of an opportunity to be the un-Apple and to open up.
Using components that are easy to recycle is one way to score points for selling an environmentally friendly product. Apple’s products rank high in that regard, says Kyle Wiens, co-founder of iFixit. But Apple doesn’t want its users to service its devices, he says. So it scores lower in another important aspect of being “green”: extending a product’s useful life by making it easy to repair. An Apple spokesman declined to comment.
In January, Sprint announced a “sustainable design” effort, in partnership with the environmental unit of UL, the independent testing and certification group. Sprint encourages all of its partner manufacturers to submit their handsets for evaluation of the “repairability and recyclability” of the devices. Those that attain a certain number of points will be designated as “certified” or, greenest of all, “platinum”. Lois Fagan, Sprint director of product development, says: “We have a self-imposed goal that at least fifty percent of our portfolio of new phones in 2012 will be certified.”
Consumers who want to know which phones are the easiest to repair won’t get much guidance from UL Environment. It will say only whether a device has earned its “certified” or “platinum” designations. It does not say what points were earned for any particular criterion, like ease of removing the external enclosure or the battery, or availability of replacement parts. Nor does it disclose which handsets fail to earn enough points to be certified.
The ability to remove the battery is especially important to frequent phone users, because the original battery may not last the two-year commitment required in a standard contract.
Apple says its iPhone battery is designed to retain up to eighty percent of its original capacity after four hundred full charge and discharge cycles. For phones out of warranty, it offers a battery replacement service for $79 if you send the phone to its repair center; shipping costs are extra. (Being without one’s phone is an inconvenience not reflected in the price.)
IFixit provides an alternative. It sells replacement batteries and the necessary tools and offers its free online repair manuals, prepared by fellow users. A replacement battery for the older iPhone 3G model is only $14.95, and there’s no painful parting with the phone in the process.
According to Wiens, iPhone batteries aren’t hard to replace, with the right screwdriver, available online. “Under five minutes; no technical skills required,” he says.
Even replacing the glass on an iPad 3 can be done by amateurs, he contends, but guidance is needed: “I have a pile of iPad 3s that we broke while trying to learn how to repair them. Last week we finally broke the code.”
IFixit offers manuals covering computers, cameras, game consoles and household appliances, too; its credo is “repair is recycling.”
Hooman Morvarid, president of CellularDR.com, a repair business that handles phones from many manufacturers, says the most frequent problem he sees is broken glass, followed by a broken LCD screen that sits behind the glass. Increasingly, he says, the glass and LCD are fused together in a way that makes them impossible to separate if one or the other is broken. “So phones are actually becoming more expensive to repair,” he says.
The more that designers of mobile devices avoid fusing parts together, the easier they are to repair. And the repairs most likely to be undertaken are those we can do ourselves.

Rico says he'll be happy to leave all this to the pros...
