Like other devices, the Fitbit wristband requires some time to get charged to the maximum.

To find out how long you should charge your wristband, we’ll need to learn how to identify the current battery percentage and how long the device lasts.

The Fitbit (Flex) wristband takes 2 hours on average to charge to 100%. With a full battery, the wristband is expected to last a few days before the charge gets low. The device should be charged for at least 30 minutes to last more than 24 hours.

How Log A Full Fitbit Flex Charge Last?

When the Fitbit device is charged to the maximum capacity, the wristband should last at least 5 full days, depending on the usage.

Some of the factors that consume the battery are the following:

  • Biometric tracking
  • Alarms and reminders
  • Step-recording
  • Calorie counting

With heavy usage, the expected 100% to 0% timeframe would be more than 72 hours.

For users that utilize most of these functions, the wristband might last a shorter period of time.

However, by disabling unnecessary features you can increase the uptime and the wristband can last up to an entire week.

Tip: You can enable/disable the Fitbit features from the dedicated application.

It’s important to know how to charge the Fitbit properly so you can be confident that the device will last as long as possible.

Here is how to reach 100% charge on your Fitbit Flex wristband in a few simple steps:

  1. Use a finger to press the Flex out of its band.
  2. When inserting the Flex into the charging cradle, make sure to hear a click.
  3. Make sure to hook up the charging cable to a USB source.

This is how to charge your Fitbit Flex wristband let’s now learn when the battery is full:

How To Know When Fitbit Is 100% Charged?

On your Fitbit Flex wristband display, you’ll see little LED lights upon plugging the device into a power source.

There are 5 LEDs in total which indicate the current Fitbit Flex charge.

When the five little LEDs start glowing, the Fitbit (Flex) is charged to the maximum.

Each of the pulsing indicators represents 20% of the total battery charge. When the very last LED starts to pulsate you’ll know that the battery is over 80%.

On a 100% charge, a green light will flash, turning OFF all 5 LED indicators, hence the device is ready for use.

Note: Without any activity, the Fitbit wristband can last up to two weeks.

The time which your Fitbit Flex wristband would need to fully charge depends on the current battery level.

As we’ve mentioned in the previous heading, the number of glowing LEDs indicates the current charge of your wristband.

It takes 2 hours for the Fitbit wristband to charge from 0% to 100%

However, 2 hours might not always be necessary since users often connect the wristband before the device completely turns OFF.

The recommendation is to keep your Fitbit Flex wristband connected to the power for at least 1 and a half hours each time.

The charge time also depends on whether the wristband is connected to another device (computer/laptop) or to a wall power outlet.

Note: Leaving the wristband connected to the power overnight will not impact the battery.

First-Time Fitbit Flex Charging!

We all know that first-time charging is quite special for every brand-new device.

This is because when the battery hasn’t been used for a long time, it might require more time than usual to fulfill the cycles and charge to 100%.

To learn how long does it take to charge a Fitbit Flex for the first time, you’ll need to leave the device plugged in for at least 2 hours.

This is the minimum time recommended for a new Fitbit wristband so if you’ve got a chance, leave the device plugged for even longer.

In most cases the brand-new Fitbit Flex would not be dead, thus it would have some charge within, but the first time you’re charging the withstand should be longer than usual.

How Often Should You Charge Fitbit Flex?

You should charge the wristband as frequently as you can.

Do not hesitate to plug the Fitbit (Flex) to power every chance you get, which will guarantee that the device won’t die when you need it the most.

The best recommendation is to charge the wristband once every 3 days, based on the usage and feature utilization.

The most features you’re using, the more frequently you need to charge the device.

Most users leave their wristbands connected to the power overnight, which fully charges the battery for the first few hours.

For the remaining time, the device is on standby (not charging).

You can’t overcharge or damage the wristband battery by frequently charging the device.

Tip: The best time to plug the wristband in the power is when the battery is at about 10-20%.

How To Increase Fitbit Flex Uptime?

When your Fitbit Flex does not last as long as you’ve expected you should definitely tweak the settings and relive some services to increase the uptime.

To do so you’ll need the Fitbit mobile application installed on your smartphone and the wristband connected to the app.

Here are some of the most resource-consuming features:

  1. All-Day Activity – You can enable/disable activities that you would like to track.
  2. Wireless Syncing – When the Fitbit continuously scans for new devices.
  3. Reduce Alarms – Fewer alarms mean less vibration, which equals less battery usage.
  4. Display – Avoid obsessively checking the track by tapping the display.
  5. Sync – Turn OFF All-Day Sync to prevent Fitbit from attempting to transfer data.
When using these steps combined, you can increase the uptime of your Fitbit Flex by a significant chunk.

However, in case you’re feeling that the wristband is underperforming, you should bring the device for an inspection to test the battery and form a conclusion.

Quick Recap:

Hence, the Fitbit Flex requires at least an hour and a half to charge from 0% to 100%, based on the current battery level of your device. The first-time charging sessions should be longer than the ordinary, and the device must be charged for at least 2 hours.
