Anyone with this phone, what battery life are you getting in usage hours? Mine if taken off charge at 7am and is about to die by 7pm Usage hours are usually between 5 and 8 hours. I could have sworn it lasted between 8 and 12 hours and nearly 2 days! Battery health says 88% but I can’t believe that. Do you think my battery is way down on capacity or is this the effect of the latest iOS ? I’d really like to keep this phone.
