Need a phone with a week-long battery? Energizer’s new beast has your back

Energizer and its collaborative partner Avenir Telecom surprised many at MWC 2024 when the two unveiled a new rugged smartphone that houses a massive 28,000mAh battery.

It’s called the Hard Case P28K and it looks like a brick. You can find photographs taken by people at the event on X (the platform formerly known as Twitter) comparing the device to other phones. There, you’ll see it completely dwarfs an iPhone. Information about the P28K was initially scarce; however, the company managed to give us the inside scoop by giving us an official specs sheet. According to Energizer, the phone has a talk time of 122 hours (roughly five days) and a standby time of 2,253 hours which is a little over three months. TheVerge in their coverage states it can “last for a whole week” of regular usage on a single charge.
