The battery might need replacing. I'm assuming this is the original battery in the iPhone? How long have you owned the iPhone for?It's an iPhone 5S with 520 cycles and 95,62% of capacity!
Well, bought from second hand, but assured that was never replaced as battery, so I'm thinking it's the original battery!
It likely could be, especially considering its a 5s and is almost four years old. If it is the original battery, then it's near replacement.Well, bought from second hand, but assured that was never replaced as battery, so I'm thinking it's the original battery!
Trust me, I did everything I could! No apps in background, no automatic updates and all the parameters and settings already optimised, still drains like hell, just by leaving it in standby!95% capacity? Holy cow, my 6s is at 86% and lasts longer. You need to look in the settings because something is working in the background. Also try "battery life" from the app store, it s a simple app that shows the life of the battery.
