When running a clinical trial, one unexpected failure can disrupt data collection, delay outcomes, and compromise compliance. Among the most underestimated risks is device battery performance. In fact, research shows that nearly 18% of protocol deviations stem from device issues, and weak battery life is a key contributor—especially in remote or long-duration studies.
At STK, we design our 5000 mAh eCOA smartphones and rugged tablets to deliver reliability, compliance, and AI-ready data capture, ensuring battery performance never puts your trial at risk.
Why Battery Life Matters in Clinical Trials
1. Preventing Data Loss and Delays
Short battery life leads to device shutdowns mid-assessment, causing data gaps and increased site workload. Reliable 5000 mAh batteries minimise these risks.
2. Supporting Remote and Decentralised Trials
In decentralised trials, participants and clinicians rely on devices for continuous data collection. Weak batteries can compromise remote patient monitoring. STK’s Titan 5 rugged device ensures consistent performance in challenging environments.
3. Enhancing Patient Engagement
Patients are less likely to comply if their device constantly needs charging. Extended battery life keeps participation smooth, reducing trial dropout rates.
4. Meeting Compliance and Quality Standards
Regulators such as FDA, EMA, and MHRA expect complete datasets with minimal deviations. By eliminating power-related gaps, STK devices ensure regulatory-ready trial data.
