How to solve the problem of inaccurate power display of Samsung I728?

This is the phone I used. I just bought it. In this case, first of all, pay attention to the normal charging method every time. At present, there is no high-energy battery of this type on the market. This is rarely true. Ok, 1500MAH can only be used for one or two days, but the function of the mobile phone is still very good. Insufficient power will make the communication function unavailable. See if your battery has not been scientifically charged, or the first three charges have not reached 12 hours, which may cause this phenomenon. I asked the customer service that the original battery should be 280 yuan. So be sure to take care of the battery!
