iPhone 5s iOS 10.2 Battery drains quickly
With the recent updates my phone keeps draining faster and faster. The other day I was using it, it was at 53% and suddenly it just shut down saying the battery was dead. When I reset and restarted the phone it came back on and said the battery was at 46%. I have to charge it about 3 times each day even with minimal usage.
I took it in to the Apple store and was told I needed to buy a new battery. When I asked why it started with the latest updates I was told the agreement says it could have an impact on older devices and that I should not update any more. When I asked if updates were needed for some apps I was told yes. I also believe that upgrades offer some security protection enhancements as well.
I am left with paying $80 for a battery on a phone that is only worth $95 on trade in and not able to take advantage of any further updates - Or buy a new phone. I just bought 2 new iPads for the family. I was hoping my phone would last a little longer than this.
I am looking to see if anyone has other ideas that might help resolve the battery draining issue?
I set the brightness way down almost to nothing. Most notifications and app tracking is turned off. I do have an Apple Watch but with few apps.
Any suggestions would be appreciated.
