Increase battery lifespan

The “lifespan” of the battery refers to the number of times in can be recharged before it must be replaced. The batteries on the iPhone and iPod touch slowly lose the ability to hold a charge after numerous recharge cycles. For example, after 400 full discharge/recharge cycles these batteries are able to store 80% of their original capacity. This percentage decreases with further recharge cycles. There are things you can do to improve the lifespan of the battery:

  • Heat degrades battery performance and can damage the battery. Don’t leave your iPod or iPhone in the sun or in a vehicle on a hot day.
  • Minimize power use to improve battery life as described previously. The longer you go between charges, the fewer charges you’ll have over time, and the longer your battery will last.
