iPhone batteries, like all rechargeable batteries, are consumable components that become less effective as they age. Each original battery after 300 to 500 cycles diminishes its full capacity down to 80% or even less. Check your battery health in Settings/Battery/Battery Health (Beta) the feature is available if your software is up to date. We fix phones and use these batteries ourselves. All our refurbished phones show full capacity and have good battery live.All batteries are tested with a multimeter before dispatch and are 100% safe and working. Same day or next day dispatch.
We dispatch items usually on the same working day with 1st Class Signed For service and post batteries to UK Mainland only. Advice: Please complete battery calibration after installation. Discharge the battery, make it drain to 0%, then charge it fully till 100% and leave for additional 2 hours. Keep your device away from moist and wet places. Keep the phone away from too hot or too cold temperatures, try to keep it at room temperature.If the battery replacement didn't help to increase the phone's battery life and the problem is related to the motherboard then you can try one of our power banks to keep the phone charged for longer.Any questions - please ask!
