ZOLEO Battery Draining Too Fast – ZOLEO

If your ZOLEO device is losing battery faster than usual, several factors may be affecting performance. This article will help you review your settings, usage habits, and environment to identify the cause and improve your battery life.

Before You Begin

Make sure you're using the latest version of the ZOLEO App and that your device firmware is up to date.
Always use the provided charging cable or a certified USB cable with a wall charger rated at 1.5 amps or higher.
If the device has been in storage for a long time, it may need a full 24-hour charge to restore battery performance.

Step-by-Step Troubleshooting

Step 1: Check Your Message Check Interval

The ZOLEO device connects to the satellite network periodically to preserve battery life.
By default, the Message Check Interval is set to every 12 minutes.
Having this low interval or having your device on Always On can significantly shorten battery life.
We recommend using a higher interval or Manual to extend battery life.
- - Note: This doesn't affect SOS alerts or Location Share+ updates.

For instructions, please see How To Change The Message Check Interval.

Step 2: Review Usage and Environmental Factors

Certain factors can impact battery life:

Location Share+ Settings – Shorter intervals between updates will consume more power. Please consider increasing the interval to get a lower battery usage.
Obstructed satellite visibility – If your device is indoors or partially blocked from the sky, it will work harder to connect to the satellite, which will use more power.
Extended active use – If you're sending frequent messages, using Location Share+, and your message check interval is set low, the device will consume battery faster.
- - Please see how ZOLEO Battery Management works.

Step 3: How You Carry Your Device

For optimal battery performance, carry your ZOLEO device where it has a clear, unobstructed view of the sky, such as on a backpack strap facing up.
Avoid placing the device inside bags or enclosures during active use.
This is specifically important when:
- - Sending a message
  - Message check intervals are active
  - Location Share+ is running.

Step 4: Update App and Device Firmware

On your smartphone, open the App Store or Google Play Store and search for ZOLEO.
If there's an update available for the ZOLEO App, please install it.
Open the ZOLEO App and connect to your ZOLEO device.
Go to the App's Settings > My Connected ZOLEO Device > About My Device > Click on Device Software Update.
If prompted to update, tap on Yes and complete the update.

Once you have completed your updates, link your ZOLEO device to your app again and test your battery life.

Step 5: Factory Reset Your Device

In some cases, an old message stuck in the device's queue or a configuration may be draining the battery.
Performing a factory reset clears all settings and any possible messages that are stuck, resetting the device's power behavior.
Please see How To Factory Reset Your ZOLEO.
After the reset, please test your battery life again.

Step 6: Charge Your Device for 24 Hours

Use a 1.5A (or higher) power source and ensure the cable and wall charger are working correctly.
Test your cable and plug with different devices to confirm that they work and provide enough power.
Once verified, plug in your ZOLEO and charge it uninterrupted for 24 hours.
After charging, unplug it and test the battery life again.

If the Issue Persists

If your device still has a shorter than expected battery life after completing this troubleshooting, get ready to contact our Product Support Team. Before contacting them, it will save you time if you send the following information in your inquiry:

Device IMEI number – This 15-digit number (starting with "30") can be found on the back of your ZOLEO device or in the box it came in.
Account number and billing address for verification – Log into your MyZOLEO account at myzoleo.com and go to the My Account section. Your account number is displayed in the top-left panel (e.g., "ZU00000"), and your billing address is shown in the lower right, under Billing Address.
A description of the issue and the troubleshooting steps you've completed, along with what happened after each step.
How long you've had the device.
When the device was last successfully powered on or charged.
If the device has been in storage, please let us know whether it was fully charged before storage and whether it has been charged regularly every six months and kept up to date with firmware updates.

Once you have gathered this information, please reach out to our Technical Support Team, and we'll be happy to assist you with the next steps.
