Quick Summary
Avenir Telecom is renowned for its rugged, long-lasting devices and the Energizer Hard Case P28K is certainly that – it has a battery inside that can last up to 94 days.
It's a decent budget phone too, with a big display and enough oomph to get the job done.
If you occasionally make phones under the name of a battery brand like Energizer, your focus surely has to be on battery life.
