That’s cheap! Really genuine?

Anyone change in Mac city before? The branch in setapak central?

I went to inquire they say can accept during weekdays, send in the morning, collect at 7pm. No need format phone.

Sounds too good to be true but I worry it's not original battery.

In my opinion, you should. Battery is generally considered not fit for purpose once its health is 80% or less (normally 2 years of standard usage).

If you are planning to change phone soon (say in 6 months time), might as well just dont bother to change the battery, but to sell it off later

If you are planning to use your phone for another year or two, or maybe even if you plan to keep this phone, better change the battery now for discounted rm121 only what   

I asked machine for appointment and they redirect me to apple site, which I made an appointment there at klcc.

I also asked through the site their customer service told me even at 94% my iPhone 8 Plus is eligible for the replacement, and if warranty is still available then it would be totally free of charge, can anyone confirm?
