Every week we have some customers that get confuse about their phone's wired issue. They say the phone can get fully charge and discharge very fast, or the phone will lose 20-50% battery all of a sudden; like it drops from 80% to 60% in a minute. Some others say the phone gets turn off when the battery reaches to a certain percentage and when they connect it to the charger, it immediately turns on. All of these symptoms are related to the Battery. The point is usually phone batteries have a life cycle between 2-3 years, each battery have different cells. When one cell in between won’t work fine, the battery would start to act wired and malfunction. This issue will solve by replacing the battery. We will do this service in store quickly.
