Swollen Battery Can Damage Your Screen #iphone #battery #broken #repair

Battery swelling occurs when gas builds up inside a lithium-ion battery due to chemical breakdown, which can be caused by excessive heat, prolonged charging, or battery aging. Several factors contribute to this issue: Playing games while charging – This generates excess heat because the phone is drawing power while also being charged, putting stress on the battery and accelerating wear. Over time, this weakens the battery’s internal structure and can lead to swelling. Using battery cases that constantly charge the phone – Keeping the battery near 100% for long periods prevents natural charging cycles, causing stress on the battery cells and shortening their lifespan. Leaving the phone discharged for a long time – When a lithium-ion battery is left completely drained for weeks or months, it can fall into a deep discharge state. This can cause chemical instability, making it difficult to recharge and increasing the risk of swelling when eventually powered up. Natural aging – Over time, all batteries degrade due to repeated charging cycles. As they age, their ability to hold a charge decreases, and the risk of internal damage leading to swelling increases. If you notice a swollen battery, stop using the device immediately and have the battery replaced. A swollen battery is a safety hazard and can damage internal components or, in extreme cases, cause leaks or fire
