iPhone 5S turns off when it is not run out

Hi there,



I was doing a run this morning and suddenly my iPhone 5s turns off. There's not even the the loading wheel you get when it normally shuts down after running out. Just a black screen, nothing. I try holding down the home button but i get the symbol which tells me to charge it.



There was no warning whatsoever about this, it just turned off. I had at least 40% battery left. The last time I had a problem like this was on a Galaxy S3 Mini back in 2015 - almost exactly the same issue. But this is the first time I've had it on the iPhone.



Is this a problem with the phone or a problem with the power in my house? The phone is used but is only about 8 months old.



Thanks,

Alex
 
Check the battery data in the settings app.

See if some apps are using an overly large percentage of battery, that doesn’t fit with how you use the phone.

My wife’s iPhone 6 was doing odd battery things - switching off when 25% battery left, and then being charged to 30% after only minutes on charge.

Facebook and Instagram were listed as using about 40% each which was too high. Removing and reinstalling and the battery meter started working fine.

Shortly after however the iPhone reported it needed a battery service. Apple said it had reached 1000 charge discharge cycles
 
When mine and my friends iPhones have done this in the past having a new battery fitted has always sorted it out.
 
Well, I've just turned it on and it's back to 40%. Odd. I've checked the LCI - should it be white with a dark orange circle?

I think that indicates that it has contacted water at some time.
 
I think the symptoms you have listed are indicative of a battery that is failing. I had an iPhone 5 that did similar things but a battery replacement fixed it. I am not sure if the water indicator also signals a problem.

See the thing is is that I had a samsung a couple of years back that did the EXACT same thing (apart from turning on again so soon) and I tried a battery replacement on that and it didn't work so I'm skeptical about spending money on batteries. But I will contact my local repair centre to get a quote
