Energizer Hardcase H590S

For Energizer, its main talking point at MWC 2018 has been about batteries. This is unsurprising given it's what the company is primarily known for. But this time it's all about the battery life in its smartphones.The Energizer Hardcase H590S doesn't have the sheer battery brute force as the recently revealed Max P16K Pro - which promises around five day's use, thanks to its 16000mAh capacity, but looks like a bit of a brick in the process. It does come packing a meaty 5800mAh, however.
