Introduction

This video investigates common concerns about smartphone battery health, specifically whether charging while using the phone, temperature exposure, wireless charging, and the final 1% of battery affect battery life. The creators conducted extensive tests over 193 days involving numerous phones under various conditions to answer these questions.

Key Takeaways

• Charging while using the phone: Using a phone while charging doesn't significantly harm the battery more than charging alone, despite higher temperatures. The number of charge cycles is the primary factor affecting battery life.
• Temperature effects: High temperatures (around 35°C/95°F and above) negatively impact battery health more than normal use. Cold temperatures can also be detrimental, as shown by one phone experiencing a significant drop (45%) in capacity, making the cold-temperature results unreliable. Normal temperature range is best for battery health.
• Wireless charging: Wireless charging itself doesn't inherently damage the battery more than wired charging. However, avoiding frequent full-charge cycles (e.g., charging only from 80% to 95%) is beneficial.
• Last 1% of battery: The final 1% of battery life isn't significantly more durable than other percentages. The 100%-99% range tends to last longer, due to slower charging near full capacity. The time until shutdown from 1% is variable.
• Battery health indicator: The iPhone's battery health indicator is generally accurate in showing the overall trend but may be off by up to 4% due to estimations used in calculating this metric.
