The smartphone with a massive battery – manufacturers should look up to Energizer

Energizer presented a 500-gramme brick with a 27,000 mAh battery at the Mobile World Congress. That’s more than five times the capacity than what you get nowadays. Read on to find out why I don’t think it’s a bad idea.

One of the highlights at the tech fair in Barcelona is the Energizer P28K. Journalists and trade visitors crowd the small stand all day long. Everyone wants to look at the smartphone, yet it’s not a thing of beauty.

500 grammes of pure fascination

The device is a hulk, 500 grammes and bulky. This is all down to the huge battery. The battery specialist has installed an energy source of 27,000 mAh and, if you used this for everyday purposes, that would mean you only have to charge the smartphone once a week.

With the battery, which is also a smartphone, the French manufacturer is addressing an everyday problem many users have. I hate that I have to put my phone on charge every night. I either forget to do it or I don’t put the device on the charging stand properly. If I leave the house in the morning with 20 per cent charge, I have a problem.

It’s a bit much, is that ok?

But I also don’t want to carry a half-kilo brick around with me. Why not a smartphone that weighs 250 to 300 grammes instead of 200 grammes and is a little thicker? The battery capacity can then be increased from the current maximum of 5000 mAh to perhaps 10,000 mAh and the battery life increased from one day to two days or more.

More battery life for a less slim design – I’d gladly shake on that. Up to now, it’s mainly been outdoor specialists such as Ulefone, Oukitel and Energizer that have smartphones with specially sized batteries in their range. It’s time for the major manufacturers like Apple and Xiaomi to rectify this issue too. An iPhone 16 Pro Supermax or a Samsung Galaxy S25 Ultralong would certainly prove popular. But maybe not the name.

The battery on the Energizer is exceptional, nothing much else

Technically and visually, the Energizer P28K is no masterpiece. Nevertheless, it fascinates visitors at the Mobile World Congress (MWC). And rightfully so in my book.

Would you accept a less stylish look and heavier weight for a larger battery in your smartphone? Let us know your thoughts in the comments!

Gadgets are my passion - whether you need them for the home office, for the household, for sport and pleasure or for the smart home. Or, of course, for the big hobby next to the family, namely fishing.
