Galaxy A32 modified with 30,000mAh battery


Smartphones have evolved a lot over the past few years. We now have 200MP cameras, 300w charging speeds, and 3nm processors, none of which existed a couple of years back. But amidst all this, smartphone batteries have largely remained static in terms of capacity. Even the biggest phones today hardly go beyond 5,000mAh.

However, Redditor Downtown_Cranberry44 took battery capacity to a new level with their modded Samsung Galaxy A32 5G. They have modified the phone with a ludicrous 30,000mAh battery.

The Galaxy A32 5G is a mid-range Samsung phone from 2021. The handset, which currently sells for less than $200, ships with a 5,000mAh battery out of the box. As said earlier, that’s the industry standard today, though the average may still be well below it.

Unless you seldom use it, a 5,000mAh battery will struggle to power the phone for two days without charging. The Redditor has solved the problem by giving the device six times its original battery capacity.

The modification involves replacing the internal battery with an external pack that consists of six Samsung 50E cells (5,000mAh each) wired in parallel for a total capacity of 30,000mAh.

The handset doesn’t look pretty, of course. It’s like a brick strapped on the back of the phone. The whole package weighs about a pound (over 450 grams). The original device weighs 205 grams, so it’s more than two times heavy now.

The 30,000mAh battery took seven hours to charge fully

According to the Redditor, the device doesn’t recognize the external battery pack and still shows its original capacity. It no longer reads the battery level as well, and always reports 1%.

The modified Galaxy A32 5G reportedly took seven hours to charge fully (likely externally determined a full charge). At the time of posting, they used the phone for two days. Since it doesn’t note the battery level correctly, it’s unclear how much charge is left. But the handset may last over a week before running out of power.

It’s not just the battery that they replaced, though. This modified Galaxy A32 5G also gained multiple charging ports. It supports fast charging via USB Type-C, Apple lightning, and MicroUSB ports, though it’s unclear if all ports charge the phone at the same speed.

Moreover, it supports reverse fast charging through two USB Type-A ports and a USB Type-C port. So the handset can be used as a 30,000mAh power bank as well.

That said, you shouldn’t do this. It’s a safety hazard. You may not be able to carry it around as well. The TSA doesn’t allow batteries above 27,000mAh capacity. This modification is just a fun project for experts and enthusiasts. Don’t try this at home.
