For years we were told that the best thing to do was charge our phones to 100%.
But with modern batteries, this practice can actually accelerate wear and tear.
If you want your phone to last longer without losing capacity, this is for you.
🔋 What type of battery do current phones use?
Most smartphones use lithium-ion (Li-ion) batteries, a technology commercially developed by companies like Sony in the 1990s and refined by current manufacturers like Samsung and Apple.
These batteries perform best when they aren't kept at extreme levels (0% or 100%) for extended periods.
⚠️ What happens when you charge to 100%?
When the battery reaches 100%, the internal voltage is held at its highest point.
If your phone remains plugged in for several hours (for example, overnight), this can cause:
Increased chemical stress
Slight temperature increase
Faster wear and tear over time
This doesn't mean it will be damaged immediately, but it can reduce its lifespan over time.
