Similar story updated IPhone 7 to IOS14.2. Battery indicator rapidly drops to 20% in a couple of hours. By 3 hours it says 1%. I didn’t have a charging cable with me but phone worked fine; Mail, browsing on Safari and WhatsApp for another 12 hours while still saying 1%. Low battery warning comes up suggesting I go into low power mode. I avoid and it seems to keep going. Notifications now accounts for 17% of my battery usage!
