Battery cannot be fully charged

If you experience the problem which is The battery doesn't be charged when power level is above 95% with AC adapter connected.

This is a normal condition for battery protection, not a problem for either the battery itself or the charging function.

When the battery is charged to 100%, it will stop being charged. At this time, the battery will self-discharge very slowly owing to the chemical characteristics of a Li-on battery even though the notebook doesn't consume any battery power.

The current design of ASUS Notebooks come with built-in RSOC (Relative State Of Charge) and the purpose is to prolong the overall lifespan of the battery. The description below can explain this phenomenon:

• When the battery capacity is lower 95% with AC adapter connected, the battery will be charged to 100%, then stop being charged.
• When the battery capacity drops from 100% to 99%~95% with AC adapter connected, the battery will not be charged until the power level drops lower than 95%.
• When the battery capacity remains around 94% to 97%, the battery will not charge with the AC adapter connected. You can unplug and re-connect the AC adapter several times to resume charging to 100%.

If you experience the problem which is The battery stop being charged after the battery level is charged to 60% or 80%.

Please make sure whether you set up Battery Health Charging in MyASUS (for some models, the Battery Health Charging is a separate app). In order to protect the battery, Battery Health Charging allows you to set your battery's maximum power of ROSC (Relative State Of Charge) which helps extend the battery's lifespan. Here you can learn more about the introduction of ASUS Battery Health Charging.

• Full capacity mode: The battery can be charged to 100%.
• Balance mode: The battery can be charged to 80%.
• Maximum lifespan mode: The battery only allows being charged to 60%.
