Why does the cold drain battery power? Most batteries work through an electrochemical reaction, which sends power signals to your terminal ends. This chemical reaction slows down in colder weather, weakening your battery's power.
Another glaring sign of battery issues is a watch that no longer keeps time, even if it still continues to tick along. This includes watches that run slow and watches that run fast. If you have a digital watch, a dying battery is the most common culprit.
If your battery is running out faster than it should, it's possible that there's something wrong with how your watch and phone are paired. You can resolve a lot of issues by un-pairing your watch and then re-pairing it as a new watch, which should wipe out any of the corruption that caused the battery glitch.

Usually, it means that your phone is detecting a cable plugged in but no power is being sent to the phone battery. Or, perhaps the phone battery is rejecting the battery charge. The reasons could range anywhere from a charger problem, to a charging port problem or even a bad phone.
Use less power: Typically, the reason why your phone is hot and losing battery is because you've been using it for a while. Take regular breaks to preserve your phone's temperature and battery life. Install junk-cleaning software: Junk files add extra work for your phone's processor and battery.
