3 Ways to Cut Your Tablet Charger Energy Bill
- 🌱
Enable optimized battery charging to avoid holding at 100% on the charger, which wastes energy and degrades the battery.
- 💡
Reduce screen brightness before charging — the display draws current even while charging, slowing the process and wasting energy.
- ⚡
Charge during off-peak hours if your utility offers time-of-use rates.
