If you have high requirements for battery life, it may not be wise to buy a mobile phone with 88% battery health, because it means that the battery has been used for a long time and cannot provide the same battery life as the new battery.
If the battery life is not high, or you just need a spare mobile phone, it may be a good choice to buy an Apple 14 mobile phone with 88% battery health. Because although the battery health has declined, other functions of the mobile phone may still be intact, and the price may be relatively affordable.
