Forget foldable phones, Energizer’s Power Max P18K Pop has a battery that lasts for 50 days in standby on a single charge.

The latest smartphone unveiled by French company, Avenir Telecom, at the Mobile World Congress (MWC) in Barcelona this week, includes an enormous 18,000mAh battery – enough to power 100 hours of music.

By comparison, the Apple iPhone XS has a 2658mAh battery.

To put this into perspective, users currently get half a day’s usage out of their phone, whereas the Energizer reportedly gives users an entire week – or up to 48 hours of continuous video playback.

But there’s a slight catch – the smartphone measures a whopping 30 millimetres in thickness, which is about the size of three-and-a-half iPhones – reminiscent of the iPod classic.

Other features of the phone include three cameras, a 6.2-inch LCD display and 6GB of RAM.

There’s no word yet on Australian pricing or when it will be available here.

‘Can’t see a stampede towards it’

According to Dr Belinda Barnet, media and communications lecturer at Swinburne University, the phone looked similar to a “brick” and saw it mostly appealing to one market.

“It’s a really good idea, but it looks heavy and I can’t see a stampede towards it,” Dr Barnet told The New Daily.

“It will appeal to the early adopter market, a small segment of consumers who are willing to pay for technology that may or may not survive.”

Energizer’s Power Max P18K Pop has an 18,000 mAh battery. That’s almost 7x the size of the iPhone XS battery!

She said the benefits of the phone included its long battery life.

“When you go on planes you can’t rely on there being a charger so this is one benefit.”

In light of 5G technology being touted at MWC this year, Dr Barnet predicted 5G would also be successful in Australia.

“4G is already filling in the gaps for NBN, so we’re going to see 5G be quite revolutionary when it’s rolled out.”

‘Wear your phone on your wrist’

If you thought the Apple Watch was impressive, then Nubia’s wearable  smartphone is something to get excited about.

Although the display measures just 4 inches (10.16 centimetres) corner to corner, it appears bigger because of its ultra-wide aspect ratio.

Nubia says the display can withstand being bent 100,000 times, which should allow you to wrap it around your wrist without risk of damage.

Nubia’s wearable smartphone also has an Android-based OS that lets you scroll the watch’s essential information, so it’s readable from any angle.

Chinese smartphone makers in the spotlight

The New Daily reported on Tuesday that Chinese tech giants unveiled their flagship devices at this year’s event.

Some products included foldable screens, 5G phones and stunning camera technologies.

Huawei is the latest company to unveil a foldable smartphone, just days after Samsung revealed its latest Galaxy Fold.

The Mate X features a 6.6-inch display, 5G connectivity, a powerful 4500-mAh battery and three rear cameras.

Oppo also revealed its latest hardware feature, an 8.6mm triple-camera system, that includes a 48-megapixel main lens and a 120-degree, ultra-wide lens and a 160mm telephoto zoom lens.

The company said it had been working on its 5G technology, with Optus and Telstra expected to have a 5G-ready phone in the second half of the year.
