Apple Event: May 7th at 7 am PT
I have an iPhone 6S which I have had for a little over a year now and is currently at 89% maximum capacity. For the last two weeks now the phone will not drop below 30-40%. The phone gets to around 38% battery life, dies then turns itself on at 14% battery life by which time it immediately dies.
Does anyone one have any suggestions on how to fix this issue?
iPhone 6s, iOS 12
Is this my only option now? Unfortunately my warranty has expired so I will have to pay for a new battery. The battery life appears to be getting worse. My phone now dies at 45% rather than at 30% like it used to. It then comes back at 45% when I charge it up again.
One thing to consider is that my lightening cable is frayed and I am only charging the phone in short bursts I’d say 20% at a time as I’m scared about both the phone and the charger overheating. If I bought a new lightning cable and charged the phone up to 100% would that make the battery problem subside?
You should not be using a frayed cable for safety reasons. Buy a good cable and see if that helps your charging situation. If not you will need to get the battery replaced. Don't go the do it yourself route unless you have the tools and knowhow to do that.
It’s always possible it might fail at any time. The symptom you describe is typically a battery that has developed high internal resistance. This does not show on the battery health percentage, but the phone will abruptly shut down under heavy power load.
That's really helpful. When the phone runs out of battery now it turns on at 54% instead of 30% initially, which means it’s going up very fast.
I worry that the phone will eventually, immediately go up to 100% battery life when I charge it by which time the battery will die as soon as I unplug it.
Is this a realistic possibility?
I tried changing the phone up to 100% using a different cable but unfortunately this did not help my situation.
Replace the battery.
Unfortunately, yes. Battery's age and loose capacity as they get older. So your only option is to get a new phone or replace the battery.

Thanks. I will try to get a new cable and see if that improves my situation regarding charging my phone. Do you think it’s possible that my phone could just die on me without warning?
No, you really need a new battery.
iPhone 6S dies at 30-40% battery
