ZS EV range dropping faster than usual - battery health?

[valentinestaveley]

So I've been driving a 2021 ZS EV for about 18 months now and it's been brilliant for my daily commute, but I've noticed over the last month or so that the range seems to be dropping off faster than it used to. I used to get around 250 km on a full charge in normal driving conditions, but now I'm lucky to see 210-220 km and the battery percentage seems to drop quicker than before, especially when I'm on the highway. I know that batteries naturally degrade over time and the heat here doesn't help, but I'm concerned that the drop has been quite noticeable in a relatively short period and I want to get the battery health checked properly before any warranty issues come up. I've been reading about battery management system updates that can sometimes help, but I'm not sure which garages actually have the proper diagnostic equipment for EVs. I found 800Sayara online and they seem to have some EV expertise, but what I really want to do is compare same day MG service in Umm Al Sheif because there are a few workshops there and I'd like to know which one actually knows what they're doing with the ZS EV's battery system. Has anyone had their EV battery health checked and found a good place that gave them honest results without trying to upsell unnecessary work? I'd love to hear from other EV owners in the area.
