It's best known as one of the most powerful and detailed system information tools for Windows, but AIDA64 is now available as a free app which can tell you everything you ever wanted to know about your Android device.
There's no flashy interface, just a vast amount of data organised into a lengthy list of categories: System, CPU, Display, Network, Battery, Android, Devices, Thermal, Sensors, Apps, Codecs, Directories and System Files.
Browse for a while and you'll find all kinds of static information: CPU type and architecture, memory and storage capacity/ utilization, GPU renderer, battery technology, wifi and network information, installed apps, codecs, system directories and more.
All this has much more depth than you might expect. Click Devices, say, and it won't just tell you that your device has a camera: you'll see its ID, image and video resolution, and the features it supports, both rear and front-facing. And there's even more on your USB devices, OpenCL, CUDA or PCI.
Even if you don't care about the low-level hardware listings, there are plenty of useful diagnostic items to explore here: battery health, wi-fi connection details, temperature information, real-time sensor displays and more.

It's very difficult to get this level of detail across all Android devices, but AIDA64 does vastly better than most of the competition, and it's regularly updated to fix problems and expand its device support.
