iPhone 5 battery replacment failed, due to U2 IC chip malfunction.
I have realized that when the Iphone 5's U2 IC chip is not working properly, once the battery is 100% dead it is toast. When replacing the battery with a new one the phone works fine, until it has completely drained again. If the phone is on it will charge just as long as it does not 100% deplete its battery life. My question is what happens to the battery that it can never work again? Can I recharge this 100% depleted battery another way, then reinstall as a new fix, instead og buying a new battery every time?
