3. Charging and Battery Life
Charging the Mouse
When the battery is low, plug the provided USB charging cable into the front of the mouse. The mouse will seamlessly switch to data-over-cable mode when connected to a PC. A full charge from empty takes approximately two hours when plugged into a PC USB port.

The G703 is also compatible with the Logitech G POWERPLAY wireless charging system, which is sold separately.
Battery Life and Indicators
The G703 features a rechargeable 720mAh LiPol battery. It provides up to 32 hours of non-stop gaming at a 1ms report rate with lights off, or 24 hours with RGB color cycling on.
You can check the charge level when the mouse is powered on, or by assigning a button in Logitech Gaming Software to check the charge level. The scroll wheel displays the charge level for seven seconds upon mouse power-on:
- Green: 50-100%
- Orange: 30-50%
- Red: 15-30%
- Flashing Red: Less than 15%
When the battery is at 15% or less, the scroll wheel will flash red. At this point, plug in your mouse to charge it. Detailed battery information, including charge level, power draw, and estimated remaining battery life, can be monitored in Logitech Gaming Software.
