Since updating my iPhone 5s to iOS 10.0.2, the battery for my phone has been draining rapidly from fully charged to nothing, just by being on standby. If I go into 'battery' in my settings and look at the 'time since last full charge' it shows that on standby it is 7 hours which is accurate from when I unplugged it at 100% charge, and usage shows 5 hours, no idea how this is possible as I have used it actively (not on standby/unlocked using my phone) for around a total of 15 mins since it was at 100% today.
Before the update my battery life has always been fantastic and I have only had the phone for a year now, but this has been happening everyday for a week and a bit now, so any help from anyone would be fantastic!
Thanks
Sean
