The lifespan of a rechargeable battery may naturally decrease over time. Having your battery die when you’re away from home can be an annoying experience, but if this constantly happens you may want to investigate whether or not your device can still actually hold a charge. While this may be a manufacturer error, it is possible that you may be draining your battery at a rapid rate. Either way, it never hurts to do a quick diagnosis to help identify the issue and to see if you can easily solve the issue yourself.
First, understand that the higher the wattage is on your device, the more quickly you’ll drain the battery. Running at high wattages will require your battery to perform at a higher level, thus draining power at a more rapid rate. To remedy this, simply turn the power down if you know that you’ll have to conserve battery life.
If you happen to have a device with removable batteries, you can quickly solve the battery dying issue by picking up a set of batteries with a higher mAh. The mAh, or milliamp-hour, is commonly used to indicate how much power a battery can hold. Thankfully, there are several batteries available with high mAhs, meaning you'll be able to vape for longer.
All that being said, if you have internal cells and you find your device is dying at an alarming rate, your device may have an unfixable error. In this case, it is best to contact the seller or manufacturer to return the item if it is still under warranty.
