MBA Early 2015 - Battery Service Recommended
Hello, Everyone. I have a Macbook Air Early 2015 model and it's been about 4 and half years since I purchased it. The Battery's Charge cycles currently is 1193. Battery's capacity has decreased drastically. I thought of replacing the battery in apple's authorised service centre in my country but the cost for a new battery would be 18000/- INR (~250$) and the service representatives evaluated my macbook and recommended me that my motherboard is corroded because of exposure to moisture and adding a new battery maybe dangerous, so they advised me to change the motherboard too before replacing the battery. It's going to cost me additional 35000/- INR (~475$) that makes it a total of 725$ just for the repairs. Amusingly I purchased this MBA for 815$ back in 2016. I can see that performance of my MBA has dropped and it heats up a lot.
I would like to know if this MBA can still be used or would it be dead one day all of a sudden? Anyone here are still using Macbooks older than 5 years without any issues? Any suggestions about what can be done?
