Back in 2019 Avenir Telecom, the company responsible for creating Energizer-branded phones, arrived at MWC with a bunch of phones promising weeks of battery life. Those same phones also had all the style and aerodynamic ability of a brick, and got roasted more than a king size bag of peanuts. Unsurprisingly the company’s subsequent crowdfunding campaign completely flopped.
Five years later and Energizer phones still exist, and Aventir has another phone with an insanely large battery life at MWC 2024 — upping the ante from 18,000 mAh to 28,000 mAh. Thankfully the design of this latest model, the Energizer Hard Case P28K, won’t see you confuse it with construction materials. But that doesn’t mean it looks particularly good either.
