Logistics and Tax Control:
Apologies to some Spanish buyers: (Balearic Islands,Las Palmas,Canary Islands,Santa Cruz de Tenerife,Ceuta)The above Spanish island areas are temporarily unable to be delivered due to logistics restrictions, please do not purchase at this time.

The difference between standard capacity and high capacity:The external dimensions are exactly the same, and the higher the capacity, the longer the duration of the phone.The marked capacity of the battery is the actual capacity (error value: 50mah), which supports testing.

Regarding duration of the phone:

The condition of the phone, the brightness of the phone screen, and the use of different functions all directly affect the duration of the phone. The external temperature and environment can indirectly affect the duration of the phone. The duration of the phone can be compared to the previous battery or directly tested at a professional repair shop for capacity.

Regarding Battery Health / Battery not recognized / Repair  window :

System iOS 18.1 can check 100% battery healthy. (But still showing unknow part and important battery message)

iOS ≤ 18.0

14, 14plus, 14pro, 14promax, 15, 15plus, 15pro, 15promax: Due to encryption issues with the original battery motherboard. It is necessary to transplant the battery motherboard to prevent repair pop ups and display 100% health. After transplanting the battery motherboard, it takes approximately 5-15 days to fully display the 100% health status of the new battery. Teaching video on transplanting battery motherboards: https://www.aliexpress.com/item/1005011574204397.html

Warning: Non professionals should not easily transplant the battery motherboard, even if the phone cannot recognize the new battery. But it will definitely not affect the use and duration of the phone.

packaging of battery ×1(Normal capacity without retail packaging)

Battery usage precautions:
1. After 3-5 cycles (5% -100%) of the new battery. The battery can maintain its optimal state.

2. Avoid overcharging:Overcharging can lead to excessive battery consumption and shorten battery life. Therefore, when charging your phone, do not charge it all the way to 100%, but try to control it between 80% -90%. This can leave a certain buffer space for the battery to avoid excessive consumption.
3. Avoid excessive discharge:Excessive discharge can also cause damage to the battery. Therefore, when the battery is low, it should be charged in a timely manner to avoid complete depletion of the battery. In addition, the "low battery mode" can be enabled in the settings to extend battery life.
4. Charging with original charger:Charging with an original charger can ensure the stability of current and voltage, avoiding damage to the battery. At the same time, it can also avoid unexpected situations such as overheating, short circuits, etc. during the charging process of the battery.
5. Avoid prolonged storage without use: Mobile phone batteries that are not used for a long time are prone to damage because they will naturally discharge. Therefore, if the phone is not used for a long time, the battery should be charged regularly to maintain its activity.
6. Avoid frequent use of fast charging function:Although the fast charging function of Apple phones can charge quickly, frequent use can cause certain damage to the battery. Therefore, when using the fast charging function, attention should be paid to controlling the frequency and time of use to protect the health of the battery.
7. Turn off unnecessary switches:In the settings, unnecessary switches such as Bluetooth, Wi Fi, etc. can be turned off to reduce battery consumption. In addition, mobile data networks and automatic screen lock functions can also be turned off when not in use.
