1. If the number of battery cycles does not exceed 500, but the battery health of Apple's mobile phone drops to 80% within one year after purchasing the mobile phone, it indicates that there is something wrong with the battery quality of the mobile phone. In this case, you can apply to Apple for free battery replacement after sale. If the mobile phone has purchased the AppleCare plan, you can apply for battery replacement within two years of using the mobile phone.
2. If the user frequently uses the mobile phone while charging (especially watching videos or playing games), the battery will be excessively damaged due to frequent charging and discharging, resulting in a sharp decline in battery life. If the health of the battery decreases and the user chooses not to replace the battery, the performance of the mobile phone will be limited to ensure the life of the battery.
3. In addition, users are advised to go to Apple Store or Apple authorized repair point to replace the original battery, so as to ensure the normal performance of the mobile phone after replacing the battery (inferior battery will affect the use and even cause the hardware failure of the mobile phone).
Mobile phone charging
1. Don't charge your mobile phone while playing.
Mobile phone batteries are very sensitive to temperature. If you find that the phone is hot when charging, please take off the protective case on the phone in time. Playing mobile games while charging will aggravate the fever of the mobile phone, which will not only lead to slow charging, but also lead to the risk of battery explosion.
2, don't charge all night
Although the current smart phone can automatically stop charging after the battery is fully charged, it is better not to charge the phone all night.
3. Don't bring the phone case.
Don't wear the phone case when charging. Nowadays, the price of smart phones is generally high, so many people worry that their phones will break when they fall to the ground. In order to avoid damaging the mobile phone, many people will wear the mobile phone case. Although wearing a mobile phone case has many advantages, it is very hot when charging, so be sure to remove the case to let it dissipate heat, which can reduce the danger.
