CPU-Z Tells You Everything About Your Phone's CPU, Battery, and More
Android: Getting detailed information about your device isn't always easy. Apps like Speccy help on the desktop, and now CPU-Z can do the same for your phone or tablet.
The app requires Android 3.0 and above (sorry Gingerbread users). Once installed it will give you extensive information about your device, including display resolution, SoC architecture, active RAM usage, battery health, temperature, and a ton more. In most cases, this app will probably be overkill, but if you've ever needed to know what kernel architecture your device uses, CPU-Z has your back.
