Unlike many brands out there, Apple does disclose the service charges that customers need to pay in order to replace a damaged iPhone display. However, it is not exactly a global policy though but fortunately, several Apple Authorized Service Providers (AASP) in Malaysia did the same too.
According to the service price list from Switch which is also a well-known Apple Authorized Resellers (AAR) in Malaysia, it currently costs RM 1790 to replace the Super Retina Display on iPhone XS Max. Naturally, the fees are slightly less for iPhone XS and iPhone XR which are listed at RM 1590 and RM 1140.
Another well-known AASP and AAR, Machines have also recently updated its service price list to include screen replacement for iPhone XS Max, iPhone XS, and iPhone XR. Interestingly, the fees are slightly higher though at RM 1999, RM 1599, and RM 1299 respectively.
Given these repair costs, it might be wise to invest in a good protective case or screen protector if you have obtained any of these newly released iPhone models. Alternatively, you can consider investing in extended warranty programs provided by some of the AAR in Malaysia such as Switch Smart Protection Plan or Machines Protection Plan.
Since AppleCare+ for iPhone is not being offered in Malaysia, these extended warranty programs are pretty much the closest you can get to having discounted repair fees for your iPhone.
