Your Wireless Device Battery

Lithium-ion batteries are used in most wireless devices because they are lightweight, can hold a charge and can be recharged repeatedly. Because these batteries are more sensitive than alkaline batteries—like those used in flashlights and other household devices—they need to be treated with care.

In order to keep your lithium-ion batteries safe and improve their efficiency, we recommend the following actions:

  • Follow the battery usage, storage and charging guidelines provided in your wireless device’s user guide. Do not open your battery pack.
  • Purchase chargers and accessories that are certified, approved or otherwise compatible with your device. If you see an example of an unsafe mobile device or accessory, please report it immediately.
  • Avoid damaging the battery by not crushing, puncturing or putting pressure on it.
  • Keep the device away from heat sources such as direct sunlight and cooking surfaces. Sustained hot or extremely cold weather or temperatures can also impact your battery’s performance.
  • Keep the battery away from other metal objects like coins and keys since they can impact its electrical connections.
  • Avoid exposing the battery to water, which could cause corrosion.
  • Avoid dropping your device, which could potentially damage the battery.
  • If you plan to store your device for a long period of time, keep your battery at about 50 percent of its charging capacity and turn the device off to prevent the battery from unnecessary use.
  • Install any updates to your operating system to keep up with the latest battery efficiency enhancements.
  • Do not overcharge batteries.

To learn more about how to protect your device’s battery, visit your device manufacturer’s website or call their customer service center.

Stop charging your battery if you see or smell smoke, fluid, other odors or if your battery looks misshapen, discolored, or is hot to the touch.

And dispose of your mobile device, battery and/or accessories properly. Wireless providers and retailers, electronics manufacturers, charitable organizations and state and local waste authorities all offer ways to donate or recycle wireless mobile devices and equipment—often at no cost to you.
