Avoid Cheap Copy Batteries
In local mobile markets like Hafeez Center, Hall Road, Karachi Saddar, Singapore Plaza, and Dubai Plaza Rawalpindi, cheap copy batteries are sometimes sold as original.
A cheap copy can look almost the same from the outside. You may only find out after fitting it when the battery gives poor timing, drains quickly, or stops working after a short time.
