Excess Service Tickets Highlighted a Critical Battery Alert Problem

Excess Service Tickets Highlighted a Critical Battery Alert Problem

Excess Service Tickets Highlighted a Critical Battery Alert Problem

After the product launched, a large number of service tickets came in reporting dead or underperforming coin cell batteries. On average, 35% of tracking devices were flagged for service, even when their batteries still had plenty of life. This created wasted service hours and unnecessary costs.

Investigating the issue, we discovered a combination of firmware limitations and inaccurate battery status alerts were the root cause. The solution focused on improving data accuracy and giving users clearer, more actionable information.

Reusable Interaction Patterns for Rapid User Improvements

Reusable Interaction Patterns for Rapid User Improvements

By leveraging reusable interaction patterns, we quickly improved the user experience for battery alerts and device replacements. These patterns allowed us to deliver clear, actionable guidance, reduce false service tickets, and streamline the path to purchase—all while minimizing development effort.

Adjusting Battery Thresholds

Lowered the alert threshold from 50% to 25% so users are notified at the right time, reducing false “Dead” battery reports. Added color-coded indicators (green, orange, red) to show urgency clearly.

Adjusting Battery Thresholds

Provided contextual guidance on battery behavior, like extreme heat or inactivity, using non-intrusive messages that help users understand their device without overwhelming them.

Direct Purchase Path

Enabled users to buy replacement devices through retailer APIs, reducing the time to find and purchase a new tracker by 75% on average.

Conditional Alerts

Provided targeted notifications that inform users of their device’s battery status and guide them on next steps.

In-App Education

Provided contextual guidance on battery behavior, like extreme heat or inactivity, using non-intrusive messages that help users understand their device without overwhelming them.
