Most smartphones are designed to optimize battery usage and minimize battery swelling. However, complete prevention remains challenging. If you frequently encounter your phone showing low battery but charges for only about 10 minutes before indicating a full charge, or if your phone feels hot and the battery is swollen, your device may suffer from battery swelling. The following article from Mytour will help you understand the causes and effective ways to fix swollen phone batteries.
CAUSES OF PHONE BATTERY SWELLING.
1. Use of Poor-Quality Chargers.
When purchasing a phone, users are often provided with accessories such as cables and chargers. As these are standard chargers, it is advisable not to use chargers of unknown origin. Low-quality chargers, typically equipped with circuit boards that obstruct proper power absorption, prolong the charging process.
2. Always Keep the Battery in Depleted State
When you constantly keep the battery in a depleted state below 10%, there's a high likelihood that your battery will easily swell because chemical reactions occur in the battery, depleting energy. The lower the energy level, the more likely the battery will swell, and the energy accumulation when full is less, reducing the battery's lifespan.
3. Using the Battery While Charging
There has been plenty of advice stating that you should not use your phone extensively while charging because doing so raises the device and battery temperatures, reducing the battery's durability. Moreover, using the phone extensively while charging can pose risks to users.
REMEDIES FOR SWOLLEN OR EXPANDED PHONE BATTERIES.
The best way to address this issue may be to replace it with a new genuine battery and develop good battery usage habits. However, the following methods may still help you mitigate this situation. However, to apply them, your battery must not have been used for more than a year and must not be swollen, and it must be a removable genuine battery. As for solid designs like the iPhone, the best way to address iPhone battery swelling is to refer to the article we shared in the previous post on how to address iPhone battery swelling.
Method 1: Clean the contact surface of the phone battery.
- Remove the battery and clean the 2 contact surfaces between the battery and the phone to enhance the battery's ability to receive power.
- Then, reinstall the battery and use the device until it shuts down completely (meaning the device turns off completely when the battery is depleted).
- Reconnect the charger to the device when it is turned off until the battery is full.
- When the device's battery is full and holding the device feels warm, wait for the device to cool down completely, usually about 3-5 minutes, then continue charging for another 5 minutes.
- Continue using until the device indicates low battery or shuts down, then repeat the cycle above from 3 to 4 times.
Method 2: Proper Charging and Discharging of the Battery.
After cleaning the contact surfaces of the battery with the phone, use it until it runs out of battery and shuts down. At this point, charge the phone battery and ensure that the charger is genuine and the contact points are not exposed.
During the phone charging process, do not turn on the device. It's best to charge the phone at night before going to bed and leave it until morning because sometimes a swollen battery may show full charge after a few minutes of charging, but it's actually not fully charged.
Once the battery is fully charged, remove the phone and wait for a while until the battery cools down before turning the device back on for use.
Method 3: Remedying a Swollen Battery.
- With the above methods, if they are not feasible, when the battery is about 20% charged, remove it from the device to cool down and wrap it in food-grade polymer paper from the refrigerator, then put the battery in the freezer compartment (at -13 degrees Celsius) for about 2 hours.
- After 2 hours, remove the battery from the refrigerator and wrap it with paper towels. At this point, you'll notice the battery sweating due to exposure to the air; after 30 minutes, dry the battery (make sure to dry the contact points thoroughly). Wait a bit longer until the battery reaches room temperature, then reattach it to the device.
- Then, use the device until the battery runs out, remove the battery from the device to let it cool completely. Reattach the battery to the device and continuously charge it for 8 hours without turning on the device.
- Repeat this process 3 times in a row; if you're lucky, you may be able to restore 90% of the original capacity.
