We’ve all been there: just when you need to use your phone the most, the battery dies.

But the days of fighting for a charger could soon be a thing of the past, thanks to Energizer’s latest device.

The tech giant’s rugged new smartphone can last almost a week on a single charge, even though it’s three times heavier than an iPhone.

With such a large battery, the Energizer Hard Case P28K is, as expected, a brick-like device, about 3cm thick and weighing more than half a kilogram.

But, after just an hour and a half of charging, it could allow talkative users to sit in front of the phone talking for 122 hours straight before running out of charge.

Meanwhile, its standby time (when the phone is on but not in use) is claimed to last more than three months.

Energizer says it’s designed for users who need a durable phone, like hikers, rather than the latest technology.

Running out of phone battery while you’re away from home is the bane of many people’s lives.

While smartphones are equipped with increasingly powerful batteries, they are also consuming much more power, with larger, brighter, higher-resolution screens and more apps running in the background than ever before.

The iPhone 15, for example, which weighs 171g and is just under 8mm thick, has 3,349 milliamp-hours (mAh).

Testing by review website Tom’s Guide has found it lasts around 11 hours of continuous web browsing at low screen brightness.

In comparison, the Hard Case P28K’s battery is eight times more powerful at 28,000 mAh, giving it a talk time of 122 hours and a standby time of 2,252 hours.

The device, which costs around £215, is just under 3cm thick, weighs 570g and can be quickly charged in around 90 minutes.

The phone, which will go on sale in October this year, is quite basic and cannot work with 5G.

It runs Android 14, has 256GB of storage, good quality cameras on the front and rear, and a 6.78-inch 1080p LCD display.
