# During charging

The MX-1000 does not hold the hosted device's battery at full capacity for a long time. This process helps prolonging the hosted device's battery life.

- For the first 24 hours, the MX-1000 charges the hosted phone or iPod to its maximum capacity (100%), then stops charging.

  If the hosted device's charge then drops below 90% charge, the MX-1000 provides power to charge the hosted device back to 100%.

- If the MX is still being charged after this initial 24-hour period, the MX-1000 allows the hosted device's battery to drop to 75%.

  After letting the hosted device's battery drop to 75%, the MX-1000 starts to charge the hosted device's battery again, but it does not charge the battery above 85%.

Note: When you remove an MX-1000 from its charger, the hosted device's charge can be as low as 75%, depending on how long the MX-1000 had been charging the hosted device's battery. This is normal.
Note: As soon as you remove the MX from charging, charging periods reset. This means if you immediately put the MX-1000 back to charging, the MX-1000 resumes the first 24-hour behavior.
