You want your phone to last as long as it can on a charge, but you should pause before you swipe away those background apps β closing them might cause your phone to use more power, not less. It's counter-intuitive, I know, but here's why.
Battery-powered tools are now powerful enough to tackle most jobs, with an ever-growing range of options from impact drivers to nail guns and everything in between. These live in your shed or garage when youβre not using themβbut this could be a big mistake.
Let's face it, you probably don't spend a whole lot of time thinking about your motherboard. Fair enough; neither do I. But did you know that there's a battery on it that can cause a whole lot of problems when it eventually dies?
The 5.3-inch Enough Phone promises Android 17, a removable battery and microSD storage, but the compact smartphone still faces a difficult path to launch.

If you find yourself lost in the woods or adrift in the ocean, a GPS-enabled Personal Locator Beacon (PLB) is certainly a handy thing to have as it will pinpoint your location for rescuers. The one [Steve Jernigan] has is relatively affordable considering it might save your life one day, but it turns out that replacement batteries for the unit are extremely expensive and hard to come by because the manufacturer would rather you send the unit back to them for refurbishment. So naturally, he took it apart and figured out how to do it himself.
His DIY battery pack consists of a small custom PCB and pair of off-the-shelf 6 volt lithium manganese dioxide cells in a 3D printed enclosure that slots into the rear of the McMurdo PLB. In assembly video below, [Steve] shows how the pack goes together and demonstrates the use of a two-part potting compound in an effort to keep the elements at bay.
Before anyone says it β putting a homemade battery pack into a device which one day might be the only thing standing between you and death is probably not a great idea. [Steve] mentions in the description of this project that this is meant for backup purposes, and that you should really spring for a legitimate battery if thereβs a chance you might actually need to be rescued at some point.
