Samsung Galaxy Phone's with Swollen Battery | what causes a swollen battery and how to fix it

What causes a battery to get swollen on a Samsung Galaxy Phones?


Lithium-ion batteries use a chemical reaction to generate power. As the battery ages this chemical reaction can no longer complete perfectly, which can result in the creation of gas. This gas will lead to a swollen battery and lost of battery health.

Defects or damage

If the battery internal layers don't maintain proper separation, due 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 have been the reason why they would catch on fire.   

How to Avoid a swollen battery on any Galaxy Phone

Samsung Battery Not Charged

Uncharged battery

Avoid leaving a battery uncharged for a long period of time. Leaving a battery uncharged can cause also lead to the creation of gases. As a result, if you have devices that you rarely use and use lithium-ion batteries then we recommend you occasionally charge them to keep the battery working.

Excess Heat

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 is because cheaper chargers tend to save money on key components and might lead to a swollen battery. 

How to Fix a Swollen Battery on Samsung Galaxy S7/S8/S9/S10? 

Puncture Battery?

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. 

Replace the battery

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.

Suggestions in Replacing the Battery of a Samsung Phone.  

  • Open a ticket with Samsung 
    • Drawback: May require phone to be shipped and they may no longer have the battery available for older Samsung phones.
    • Pro: The battery will be an original battery and replaced by trained technicians
  • Independent phone repair service center
    • Google search "cell phone repair store near me" and get a quote by calling. Look for 5 star rated stores and more than 30 reviews. *Please note that not all phone repair stores do all phones so just call
    • DrawbackNot all service centers have a good reputation so make sure they can be trusted with your device. You may also live in areas where the nearest location is miles away.
    • Pro: They will have the tools necessary to do the repair. Ask what type of warranty they have for their battery replacements. 
  • Going the DIY route
    • Go to Amazon and search for a battery there. They usually come with tools to do the repair. *I'll add a few links later in the future for all Galaxy phones
    • Drawback: you will be required to do research (watch a few YouTube videos) and labor for the replacement. Battery may not be original. You run the risk of something going bad and causing you more money.  
    • Pro: Chances are that a swollen battery may have lifted your back glass, if that is the case then removing the back glass on the Samsung phone becomes easier. You save yourself a lot of money
