Vivo is the company that has produced some of the most intriguing and powerful handsets in the past few years. Just to name a few: Vivo X300 Ultra, Vivo X Fold 6, Vivo V80.
Soon, Vivo might stun us again with a 12,000 mAh phone. Yup, that's more than three times the battery capacity of the good ol' iPhone 17 (~3,700 mAh) that millions of people swear by and use every single day.
Some big numbers

It's not yet clear which Vivo phone would be housing this mind-boggling battery capacity, but I guess we'll find out in early 2027. Per the latest rumors, this isn't even the end of the story for Vivo. The Chinese brand might be planning even bigger batteries for the near future and those would be reserved for devices with large displays.
Which means that the 12,000 mAh battery might be fitted in something that's under 7 inches in diagonal and that isn't too thick.

What's the capacity of your dream battery?
How is this possible?
Ask any tech nerd and you'll get the same answer: Chinese phones are increasingly packing silicon-carbon (Si-C) batteries, which, in turn, pack more energy into less physical space than traditional graphite-based lithium-ion batteries.
We no longer have to choose between a slim design and a large battery.
Of course, that depends entirely on your phone usage habits. Some people have no problem burning through 5,000 mAh worth of battery in a single afternoon. In any case, such technological breakthroughs are fascinating.
But the tendency is to push it as far as one can, as fellow Redditors are discussing here.
A wider foldable is in the menu, too
Vivo's plans apparently include a new foldable in 2027. And, judging by what we saw happen in 2026 on the fold front, I'm willing to bet a reasonable amount of money that Vivo will come up with a wide foldable to counter the alleged successors to the iPhone Duo and the Galaxy Z Fold 8.
