This brand could be developing a phone with a 10,000mAh battery

Think phones with 9,000mAh batteries are a breakthrough? Wait until you hear this rumor about a possible Vivo phone that's supposedly being tested. 

Vivo might be testing a phone with a 10k+ mAh battery

In a recent Weibo post, renowned tipster Digital Chat Station claims that Vivo is currently developing a smartphone with a 10,000mAh battery. Supposedly, this battery beast would pack a 4.53V single-cell silicon battery. What's more, the typical value of this monster is said to be 11,000-12,000mAh. 



Now, this already sounds pretty remarkable, but the real highlight isn't the mAh — it's between the lines. 

How Vivo is changing the battery game

What's truly special about this leak is that Vivo is supposedly using a single-cell silicon battery with an extremely high voltage. Let's break it down.



The OnePlus 15 features dual-cell technology and packs a 7,300mAh battery. While this is already huge, this particular technology results in about 10% "dead space" under the chassis. This is because all the protection boards and wiring need to be connected in a stable way, and it also results in faster charging speeds. 

Vivo could be choosing another approach. Instead of relying on a dual-cell technology, it could aim to utilize the most internal space. The brand could adopt a higher energy-storing silicon-carbon material. Put simply, this phone may come with more energy while maintaining a relatively thin design that doesn't feel like a brick in your hand. 



Also, most phones' batteries have a maximum cutoff voltage of about 4.4V — they simply stop charging beyond this voltage. And if you try to bypass this threshold, the device may become downright dangerous. 

Vivo is stepping things up by pushing the battery chemistry to 4.53V. This is basically an "overclocked" chemical density — and it could be the key to how the brand can push the capacity to 10,000mAh without making the phone too bulky. 

And yes — phones with single-cell batteries tend to charge slower, but they last longer on a single charge.

Too early to say

At the end of the day, it's way too early to say whether Vivo will indeed launch a phone with a 10k mAh battery — regardless of how reliable the tip is. Technical problems could always arise during the testing period, which could make the brand reconsider. 

But the bottom line is this: Vivo is pushing the boundaries and striving to make the dream of a true multi-day phone finally possible.
