IPhone 4s shuts off with high battery

Your statements are very true. I have had my phone since October 2012. This issue has persisted since that point. I just recently had apple test the battery and the health is actually very good, according to their testing. They tested for hardware faults, there were none. So they rest the iOS to the most current. Nothing has changed. The phone drains from 50/60% to 25% and then dies. Once plugged in, it reads 38%. If it's not the battery, not the hardware, it can only be the software.

Previously I was using the 4s 16Gb and did not encounter this problem at all, however, I mostly used that one as a music player and didn't keep a SIM card in there (basically I'm flight mode 95% of the time, and WiFi for the rest). In Jan 2014, I upgraded to the 64Gb 4s and used it as a phone with the SIM card in and not in flight mode. This is when I noticed the random shutdown issue at various battery levels, typically from 10-35%. I had that phone replaced, but still encountered the same issue. I'm now on my third 64Gb 4s and still finding this problem occurring. I've had the hardware checked and was told the battery was in excellent condition. I've also done what most people here have and used the latest software and carried out multiple factory resets.

This is really disappointing as this thread was created way back in 2012 and the issue still hasn't been resolved!

Upgrading from iOS7 to iOS7.1 fixed the problem for me.

It took me a litte way to figure out the solution, but got it easily. Anyone can do it. Don't need to be a computer geek or a genious to find the solution. Two steeps takes you there 🙂. Reseting your phone or changing batteries has nothing to do with it, indeed can be a waste of time.

OK , so? what did you do?

Hello folks.

My experience is simple as **** :-)) well imagine over-the-warranty car trying to go up the very steep hill... that is exactly what we pushing our iPhones to do, while heavy-using it... esepcially in Cold weather + 3G/4G on + Cellular data on + Weak cell signal <=> result is the engine (battery in our case :-)) dies suddenly. Simply replace the engine (battery) with brand new one n Voila! car is going fine again! for about a year (dunno how in ur country, we here have 6mth warranty on batteries, so anything >6mth is a gift :-)) I did it with many iPhones n worked like a charm over n over again :-)) Good Luck every1 ! n Happy iPhoning :-))

These DFU and Restore and Resets and Battery Recalibration did not work for me.

I have suffered with this switch off problem for 6 months now. Finally I think I may have fixed it.

Firstly, just turn the phone to low power mode after a full charge and revel in the long battery life. Irrespective of the excitement you will see in the battery lasting so long, do observe whether the phone turns off or not.

If you find that the phone doesnt turn off, then it is clear that there is no hardware problem. Now your culprit is either an app that uses background data, or an app that uses location.

For me, turning off background app data worked and my phone drained power gracefully and turned off only after 1% charge. When I turned it back on I started getting shutdowns at 40% or 20%. I seem to have narrowed it down to whatsapp.

Try turning off the background app data for whatsapp, or better still, uninstall that godforsaken app and your $500+ iphone will show no battery problems.
