Having received a replacement battery from CE Store, the phone is now OK with top battery performance. The one received earlier was just a scrap, not chargeable. Now, I’m quite satisfied.
Crushing experiment! The phone wakes up, all installed apps appear on the screen, works well, joins to Wi-Fi, but can’t charge the battery. 1% still remains after three hours, connected to its genuine charger. Well, I’m down and very sad.
The battery replacement took 50 minutes. The taptic engine took a bit more extra 10 minutes time.
