Is Your Smartwatch’s Battery Life a Constant Struggle?

Is your smartwatch running out of battery, and you are facing challenges in charging it? To stay connected the whole day, you must recharge your smartwatch in several convenient and innovative ways. Before discussing the exciting ways of charging, I want to tell you the tips for charging.
Helpful Tips for Charging a Smartwatch
If you follow the manufacturer’s instructions for charging and tips, then you can find which charger is compatible with your smartwatch and which method is suitable. Let’s discuss which tips you must keep in mind while charging your smartwatch to enhance Li-ion battery charging speed and prolong lifespan:
1. Compatible charger
Using the compatible and proper charger while charging your smartwatch can maintain your battery lifespan and efficiency. Because using rapid, discounted, and wrong chargers will shorten the battery lifespan and damage your watch.
2. Optimum temperature
If you want to charge your smartwatch properly and efficiently, then charging at optimum and moderate temperatures is mandatory. Charging in extremely hot or below-freezing points can damage and affect the battery’s lifespan.
3. Dirt and corrosion-free Smartwatch
Before charging, you must ensure that your charging tool, ports and contacts are free of dust, debris or dirt. A single drop of moisture can cause rust to electromagnetic pins or contacts that can prevent charging and data transfer. Before charging, wipe the watch with a cloth piece to dry it fully.
4. Properly Placed Smartwatch
Place your smartwatch in a flat and well-ventilated area before charging. It also helps to enhance the charging speed of the watch.
5. Powered off the Smartwatch
You must make sure that your smartwatch is powered off before charging. If your powered-on watch remains connected to the charger when fully charged, it will create stress on the battery and shorten its lifespan.
6. Avoid complete discharging
The devices are designed to be booted down while they are powered off. Your device will not have gone through a power cycle when discharged completely. That’s why it’s better to avoid the complete discharging of your smartwatch. Also, please don’t operate your watch when its charging is very low (2.5% or below).
If you follow the above tips, you will enjoy your smartwatch’s smooth and interruption-free running.
