I’m interested to hear from anybody who has ever had an iPhone battery replaced over the counter in a high street Apple Store. Specifically, did they do it while you waited? Or while you went shopping? Or did they send it away for a few days?
I’m unable to (easily) get an answer from Apple as, whilst the nearest shop does list a phone number with appropriate area dialling code, it is answered by a robotic system that just fobs me off into the global support queue, no matter what question I ask. The wait time of 10 minutes, with zero confidence that I’ll actually get through to anybody in the local shop, means I give up at that point.
I know iPhone batteries can be had more cheaply elsewhere, but the Apple advertised price is not that unreasonable, £50 for a 6S. I can book an appointment at the local shop, the next step is unclear. I’ll be peeved if I make a special trip into town only to be told “yes we know you booked a slot, but we can’t do it today”.
