Your phone’s power usage can reveal where you’ve been

When you think of smartphone location tracking, both legitimate or otherwise, and you will most likely think of technologies that directly relate to locations, like GPS, WiFi, or even Bluetooth. But a group of researchers from Standford University and Israeli defense group Rafael are proving even something so innocent sounding like your phone's battery consumption can be used to track your movements.

Apple faces lawsuit over EV battery expert poaching

Apple's electric car project may only have been grist for the rumor-mill for a week, but it's already landed the firm in legal hot water over alleged expert-poaching. Speculation about the so-called "Project Titan" underway at a secret facility near Apple's Cupertino headquarters has so-far centered on intermingling rumors of EV powertrains and self-driving technology. However, according to battery maker A123 Systems, some of the skills that are helping those projects came as a result of a targeted campaign by Apple to grab the firm's staff.

EasyAcc 10,000mAh portable battery mini-review

A portable battery seems like an unnecessary burden until that one time you really need it, then it's worth its weight in gold. Not all external batteries are created equal, however, and investing in the wrong one could mean endless fiddling to make sure it's still charging, trouble getting it to hold a charge, and frustration when it fails in the middle of your weekend getaway. I recently got my hands on EasyAcc's 10,000mAh portable battery, and having been burned (in the non-literal sense) by external batteries in the past, I was skeptical about how it would hold up.

You're out and about and your phone's battery indicator starts flashing. An inconvenience, usually. In less favorable situations, you might be stranded somewhere waiting for the tow truck to call, only for your battery to turn red as its final farewell. Whatever the situation, users will find a portable (external) battery handy when the battery is running low, topping it up enough to last a couple more hours, or, in some cases, completely recharging it for another day or so of use.

Situations where a portable battery is likely to get wet, dropped, bounced around, or otherwise handled roughly are all welcomed territory for Dark Energy's new Poseidon rugged portable battery.
