Realme Showcases Prototype Phone With 10000mAh Battery
Usually, you will find phones with 5,000mAh batteries even in flagship phones like the Samsung Galaxy S25 Ultra. However, the emergence of silicon-carbon batteries has raised the bar with phones sporting anywhere from 6000mAh to 7000mAh batteries.


Some phones, like the iQOO Z10 and the Honor Power, offer 7,300mAh and 8,000mAh batteries. But Realme seems to have beaten them all with the Realme GT 10,000mAh, packing a humongous 10,000mAh battery.

It can easily last five to seven days on a single charge, and the best part? It’s thinner than your average smartphone at just 8.5mm. Imagine an entire week passing by and you don’t need to charge your phone; that’s crazy.
Compared to something like the iPhone 16, which has a 3,561mAh battery, or the Galaxy S25, which has a 4,000mAh battery, it seems like a monumental leap.
How Did Realme Manage To Fit This Huge Battery?


But how did Realme achieve this? Well, by using denser silicon carbon technology, roughly 10%. Realme calls it the ultra-high silicon anode battery.
This allows them to fit a huge battery in the same body as a regular-sized phone. The phone has a transparent back and the world’s smallest Android mainboard.
This means you huge battery capacity without the hefty bulk that comes with it. It weighs only 210 grams, which for comparison, is lighter than a S25 Ultra.
Well, this Realme prototype can also charge other phones, doubling up as a 10,000mAh powerbank. You don’t need to carry those bulky power banks any longer.
And unlike a powerbank, it is slim enough like a regular phone to fit inside your pocket. But what about the charging time? Well, it is rumored to support 100W wired charging, which is faster than most flagship phones out there.
This means that a full charge should take around an hour, which is just lightning fast. If you are suffering from battery anxiety, then this phone might just be the cure. Who knows, we might even witness phones with 15,000mAh or 20,000mAh in the future.
