Fast Charger - Speed Charging is a free utility tool designed to provide information about your smartphone’s current software and hardware status, including memory, temperature, charging status, and more. Despite the app’s name implying its fast charging function, this isn’t entirely accurate, as it is a hardware feature, not a software one.

Get to know more about your device

Fast Charger - Speed Charging gives you an interface with two options: Device Info and Battery Info. In the latter option, you’ll find info about your phone’s battery time, quick toggles, temperature, voltage, and battery technology. On the former, you’ll find more info about your phone’s hardware, including CPU, memory, and more.

There’s also an optimizer built in that offers basic optimization, but it appears that it isn’t working. Same as the charger function, which ‘sends’ your device into speed, continuous, or trickle charge mode, but this is false since the charging speed is tied to its declared speed by the manufacturer.

An unnecessary app

Unless you have an old phone or find a specific use for it, Fast Charger - Speed Charging is unnecessary due to its features readily available on smartphones nowadays, which are more useful than this app. It gives some useful insights about your phone, sure, but the advertised ‘fast charging’ didn’t work.
