Does fast charging shorten smartphone battery life? HTX Studio’s lab tests dig in

German tech YouTube channel HTX Studio recently published an in‑depth video investigating how modern fast‑charging systems affect smartphone battery longevity. The creators use a laboratory‑style setup to evaluate whether quicker charging cycles accelerate battery degradation.

The video aims to answer a question many users have: is the convenience of fast charging worth the potential long‑term cost to battery health? HTX Studio’s testing approach appears methodical, and the episode covers the test rig, charging profiles and the metrics used to track capacity loss over time.

What the video covers

• Overview of the fast‑charging standards tested and which phones/adapters were used.
• Details of the test setup (controlled charge/discharge cycles and monitoring tools).
• How battery health and capacity were measured across repeated cycles.
• Practical takeaways for everyday users about charging habits and preserving battery life.

We won’t spoil HTX Studio’s conclusions here — the tests are worth watching if you rely on fast charging daily. You can view the full video on HTX Studio’s YouTube channel (opens in a new tab): HTX Studio on YouTube. For the original German write‑up, see iphone‑ticker.de.

Quick tips from battery‑care best practices

• Avoid keeping batteries at 100% for long periods; remove the charger when practical.
• Use the charger and cable recommended by the manufacturer to reduce stress on cells.
• Consider using optimized charging features (where available) to slow charging near full capacity.
• If you must fast‑charge frequently, occasional slower charging sessions may help balance convenience and longevity.
