    Welcome to iMore! You could try recalibrating your battery, which ensures that your battery and device are on the same page regarding your battery percentage.
    1. Charge your device to 100%
    2. Unplug it and then use your device until it shuts itself off (runs out of battery)
    3. Recharge to 100% with no interruption in charging.
    It may or may not help but it's worth a try. What device are you using? If it's an older model your battery might just be nearing the end of its useful life. Apple's iPhone batteries, for example, are designed to retain 80% of their original capacity for 500 full charge cycles. After that you're on borrowed time.
