### ⭐ Overheats and drains fast
*by T***K on 30 June 2025*

I purchased this battery for my iPhone 12 Pro, hoping for an upgrade in performance, but it turned out to be a huge disappointment and a potential safety risk. The battery gets very hot during normal use and charging, even when the phone is idle. It also loses charge extremely fast — I tested it with the phone completely powered off, and it still lost over 90% of its charge within just 6 hours. That’s completely unacceptable. Despite following all installation instructions carefully, the battery is clearly defective or unsafe. I’ve removed it from the phone because I don’t feel safe using it. I cannot recommend this product to anyone. Stay away from this battery – it’s not worth the risk to your device or your safety.
