A:Answer Thank you for your inquiry about our product, JB. Using your phone while it is charging may shorten its battery life. The smartphone fails to fully charge when in use, resulting in the phone becoming warmer than expected. Using it while it's charging will use more power, making it take longer to fully charge. To improve the battery life of our phone, it is still better to charge it first before using it. If you have other questions or concerns, please send us an email at supportforums@motorola.com. We're here to help you out. -Rizza
