Overnight Phone Charging: Is it safe? How to protect your battery life
•Modern smartphones (iPhone, Samsung, Google Pixel, OnePlus) prevent overcharging, but prolonged 100% charge degrades lithium-ion batteries.
•Keeping battery at 100% for hours causes high voltage and heat stress, reducing capacity over 2-3 years.
•By 2026, most major brands offer 'Optimized/Adaptive Charging' features to mitigate this issue.
•These features learn user routines, charging to 80% and completing to 100% just before wake-up, or limiting charge to 80-85%.
•Best practices include using optimized charging, original chargers, avoiding overheating, and keeping charge between 20-80% if smart features are absent.
