This post will cover some general specifications of tablet computers. If you're new to the series, you might want to go back and read Part 1 (types and basic information) and Part 2 (size and operating system). When you're ready, come back to this page to learn about other specs like storage and battery life.
Storage
Most tablets have options for how much storage capacity is available on the device. Keep in mind that with some tablets that use flash memory, like the iPad, it's impossible to add more internal storage at a later date. (The iPad does not offer a USB port or card reader, but there are other options for external storage.)A range of 8 GB - 64 GB seems to be the most common for consumer tablets. Some rugged tablets have storage capacities of 256 GB or more.
How much storage you need depends on how you'll use the device. Do you want to store photos, music, or videos? Will the tablet be for work with lots of apps? Will you download game apps that have a lot of graphics?
Say your device will be broken up this way:
- 25% photos
- 35% music and videos
- 20% apps
- 20% other (like the operating system)

Battery Life
Once you've got all of your files on your device you're going to wonder how long it'll last between charges. Reported battery life varies between resources - what the manufacturer says may vary from what you and other users experience. Battery life can vary based on what apps you're running, screen backlight brightness, and whether you're taking photos or watching a movie.culled from appliance technology
