Does your phone get too hot while charging? Incorrectly charging your phone in the summer can be a serious disaster. To preserve battery life and avoid the risk of explosion, follow these charging rules. We often hear about phone batteries exploding during the summer. Let's understand the underlying cause.
Smartphones have become an integral part of our lives. However, rising temperatures in the summer are a major threat to phone batteries. We often hear reports of phone batteries exploding during the summer. This is primarily due to heat and improper charging.
How much percent should the phone be charged in summer?
According to technicians, you should never charge your phone to 100 percent in the summer. Battery temperatures are already high in the summer, and fully charging puts chemical stress on the battery. The safest approach is to keep your phone between 20 percent and 80 percent charged. Once the charge reaches 80 percent, unplug it. This prevents the battery from overheating.
The 20-80 percent rule
increases battery life: Following the 20-80 percent rule increases battery cycle life and prevents swells. Internal components are protected because the phone doesn't heat up. When the battery stays cool, the phone doesn't freeze and runs faster.
Improper charging methods:
Charging at 100% in the summer and simultaneously gaming or using the phone excessively can cause the battery to explode. Heat drains the battery faster. Excessive heat can permanently damage the phone's display or motherboard.
5 things to avoid in the summer!
Charge with the cover removed: When charging your phone in the summer, remove the thick back cover to allow heat to escape.
Don't keep the phone under the pillow: Don't charge the phone under the pillow or mattress while sleeping at night, as this prevents the phone from getting air.
Avoid leaving your phone on the car dashboard. Leaving your phone in a car parked in the sun is inviting an explosion.
Be careful with fast charging: If your phone is overheating, try using a regular charger instead of a fast charger for a while.
Don't charge while in use: Avoid playing games or making video calls on the phone while charging.
Whether your smartphone is expensive or inexpensive, the heat is the same for everyone. Charging the battery to 80% and storing the phone in a cool place is the best way to stay safe.
