I am using iPhone 7 and from few months my phone battery is draining 100% in 6 hours stand by time and Battery Health was also showing 84%. Recently tried replacing Battery even it is in normal peak performance but still facing same drain issue with 8 hours standby time and 100% Battery health.
Tried all the settings related to battery, restore factory settings but still same issue. One more thing observed is even if I swithoff the phone also it is draining in same time. Please suggest.
