Things to consider when buying a smartphone - Battery

6. Battery

Read reviews or talk to people who already own the phone you're interested in buying. You want one that's going to last all day, if possible. The biggest complaint I get from friends and family is that their smartphones are "always dead." If you're in this bunch, consider a smartphone with a fast charging battery.

Most Android smartphone makers include the special chargers that can juice up a battery to at least a half charge in just minutes. Or, if you own an iPhone, consider buying an iPad charger to get more juice.
