Top 10 smartphones with strong battery life

Because a smartphone is only as smart as its battery

While it's important to have a smartphone with the latest features and technology, it's just as important to have a strong battery life to support it. A smartphone is capable of numerous things and can substitute for one's computer in many situations. This includes times when you need something lighter but still capable of accessing the Internet, creating documents and viewing media files.

The longer the battery life of a smartphone, the more connected you can be to the world. And with smartphones providing entertainment as well, no matter where you are, you'll never be bored. Here's our top 10 of smartphones with the best battery life.
