No one on our team is exempt from the temptation to have the latest, greatest whatever. But we have gotten into the habit of reminding each other it is not always necessary. Frequently not. Almost never, actually. We never tire of sharing, and hope you never tire of reading, new stories about re-use, recycle and up-cycle options in our every day lives:

Choosing to Skip the Upgrade and Care for the Gadget You’ve Got

By BRIAN X. CHEN

Vincent Lai was working at a recycling facility in New York and sorting through a bin of used cellphones a few years ago when he dug up a Palm Treo, a smartphone that was discontinued last decade.

Mr. Lai, 49, tested the Treo and found it still worked. So he took the device home and made it his everyday mobile companion, much as one would adopt an abandoned animal on its way to being euthanized.

“That’s how I think about a lot of my tech stuff: candidates for 11th-hour pet rescue,” said Mr. Lai, adding that he was fired from the recycling facility in 2010 after continuing to take home unwanted gadgets, against the wishes of his boss. Now he works for the Fixers Collective, a social club in New York that repairs aging devices to extend their lives.

Many tech companies are trying to train people to constantly upgrade their gadgets — part ways with a device, the argument goes, as soon as something newer and faster comes along. Companies like Apple, AT&T and T-Mobile USA now offer early upgrade plans that allow consumers to buy a new cellphone every year. Philip W. Schiller, Apple’s senior vice president for worldwide marketing, said at a product event last month that it was “really sad” that more than 600 million computers in use today are more than five years old.

Mr. Lai’s behavior might be extreme, but his experience with the Palm Treo illustrates there is another way: If you simply put some maintenance into electronics as you would a car, you can stay happy with your gadgets for years.

It is part of a movement of anti-consumerism, or the notion of cherishing what you have rather than incessantly buying new stuff. Signs of this philosophy are spreading: Industry data suggests that consumers are waiting longer to upgrade to new phones than they have in the past.

So in observation of Earth Day on Friday, Mr. Lai and Kyle Wiens, the chief executive of iFixit, a company that provides instruction manuals and components for repairing devices, offered their advice on getting the most mileage out of a smartphone, tablet and computer.

Mobile Device Maintenance

When smartphones and tablets were fairly sluggish and limited in abilities compared with computers, there was a compelling reason to buy a new mobile device every few years. But now the mobile gadgets have become so fast and capable that you can easily keep them much longer.

“A five-year-old computer is still completely fine now,” Mr. Wiens said. “We’re starting to hit that same plateau with phones now.”

Maintaining smartphones and tablets is fairly easy. Just two critical features require attention: data storage and battery capacity. If a device is close to running out of storage, the operating system may slow to a crawl. And if the battery is near the end of its life cycle, the device will run out of juice more quickly than it once did.

So how do you free space? For Android phones and tablets, Mr. Lai recommends storing personal data like photos, movies and downloaded files on a removable memory card. That will open up room on the device’s internal storage, allowing the Android system to run more quickly.

On Apple’s iPhones and iPads, which lack support for removable memory cards, managing storage can take more sleuthing. One clever tip recommended recently by a user on Reddit.com was to rent a movie on iTunes that exceeds the amount of space you have left. When the device detects it lacks room for the movie file, it rejects the download and clears out cached data lingering in apps. I tested this method by downloading the new Star Wars movie on a three-year-old iPad that was nearly out of space; it freed two gigabytes and sped the tablet significantly…
