Say goodbye to low-battery panic. realme has just pulled the curtain on a bold new concept: a smartphone with a massive 10,000mAh battery — all packed into a sleek, surprisingly slim design.

Yup, you read that right. Despite this giant battery, the phone is under 8.5mm thick and weighs just over 200 grams, proving that big power doesn’t need to come with bulk.


🔬 Innovation Inside and Out

realme isn’t just stacking in a bigger battery — they’re reinventing how it works. This concept device uses an ultra-high silicon anode battery with the highest silicon ratio in the smartphone industry (10%) and an energy density of 887Wh/L. Translation? More power, less space.

To make it all fit, realme introduced a new “Mini Diamond Architecture”, shrinking the Android mainboard to a record 23.4mm — the world’s narrowest. The result: more room for battery without sacrificing performance. And through the semi-transparent back, you can even see the futuristic internal design for yourself.


⚡ realme’s Battery Legacy Keeps Growing

This isn’t realme’s first battery breakthrough. From the 150W GT Neo3, to the 240W GT3, and even a 320W concept phone in 2024, the brand has consistently pushed fast-charging and endurance to the next level.

Now, with this 10,000mAh concept and the GT 7 Series on the horizon, it’s clear realme is aiming to become the go-to brand for battery innovation in the smartphone world.


Big battery. Smart design. Industry-first innovation.
The future of mobile power is coming — and it’s coming from realme.
