Up to 5 days

The trackers in this section are the majority of Fitbit since Up to 5 days is the regular battery life that comes in most Fitbits, is a cool mark since you don’t have to be to worry about charging your device constantly like with most trackers that have a 24 or 48 hours battery life.

On the other hand, there are trackers like the high-end line of Garmin that can go to more than 2 weeks without the need of a charge.

There’s something that we need to mention, that in the case of the Ionic that will happen with most tracker that comes along with GPS ( also happens with the Garmin watches), is that when using GPS your battery drops quicker, so in the case of the Ionic if you don’t turn off your GPS your battery instead of last 5 days will be done after 10 hours.

Have in mind that the Ionic is the only one that comes with built-in GPS all the other Fitbit will use your Phone GPS pairing it by using Bluetooth.
