🔋 Tech Tip from Tech Node

Did you know that charging your phone overnight every day can reduce its battery life?
When your phone stays plugged in for too long, it continues to receive small charges even after reaching 100%, which puts stress on the battery over time.

To keep your phone battery strong and lasting longer: ✔ Charge your phone before bedtime
✔ Unplug it once it reaches full charge
✔ Avoid leaving it plugged in all night
