Lithium-ion batteries use a chemical reaction to generate power. As the battery ages this chemical reaction no longer completes perfectly which can result in the creation of gas. Leading to a swollen battery and lost of battery health.
If the battery internal layers don't maintain proper separation, do to damage or defects, can result in swelling or in small instances even an explosion can occur. If you remember the story of the Samsung Galaxy Note 7, a defect could of been the reason why they would catch on fire.
Avoid leaving a battery discharged for a long period of time. Leaving a battery discharged can cause the creation of gases. As a result if you have devices that you rarely use and have lithium-ion batteries make sure that you occasionally charge them to keep the battery working.
You should also avoid exposing the battery to excess heat or charging the battery too often since this would ware of the battery much quicker
Purchase high-quality chargers. The reason why purchasing high-quality chargers are important because the cheaper chargers tend to save money on key components that might lead to a swollen battery to occur
Absolutely Not!!!! While doing research on swollen batteries I saw a couple of videos suggesting you carefully puncture the battery to remove the gas and put a tape over the whole. This is extremely dangerous plus putting a defective battery back into the phone doesn't make sense.
Undoubtedly replacing the battery on your Samsung Galaxy phone is going to be the best option to fixing a swollen battery. Replacing the battery will give your phone better battery life and extend the life of the phone.
