Hi Robin,
I’m using iPhone 11 and my battery percentage decreased to 79%. So I decide to replace my battery. So I searched an authorised service centers near me through Apple official website. I got few suggestions. My question is both iCare and iPlanet Care were authorised, but the battery replacement charge is higher in iPlant Care when comparing to iCare. So could please help me with this. Which one is better whether iCare or iPlanet Care. Thank you.
Hi Bro, if you can see iCare in Apple Support app on your iPhone then dont worry. Price difference may be there due to stock they got and pricing strategy they have to attract more business. Replacing battery from any apple authorised service center will be good and safe.
