iPhone 5 shutting down with 20% battery life left

Hi

I had the same problem, my iPhone 5 shuts down at 25-30%.

I restored iPhone with iTunes, and it didnt help...

What can i do? since i bought this iPhone a year ago it never last for more the 2-3 hours.

this seems to be strictly limited to new OS (ivy++. Bring back Forstall NOW.!!). I upgraded to new OS and next day % started jumping.. I disabled all background app but that hardly made any difference. I notice that the problem is worst with any data cellular connection and with camera. Open a page and battery runs down 30-50% before the page finishes loading.! I am an avid reader and can clearly see that the problem is caused by new software. Also, for some reason battery seems to be running hotter ie it heats up quite quickly witheven data connection is active on cellular. probably some NSA spyware with new software? who knows.!

Hi skennedy1023,

I'd like to try your method of resetting my phone however my sleep/power button doesn't work.

Do you know a method of hard resetting my phone using assistive touch or if there's another method of hard resetting?

the iphone randomly shuts down with charge >1%, how do i drop it to 1%????

guys hope this will work ... i tried this and work first you can reset your iPhone

and then u can simply attach your iPhone to laptop and you charge your phone until 100 percent with laptop and then unplug your phone and use your battery hope it will also work with you its simple

I have tried the method you've stated on my iPhone 4S few times, but I can only drained the battery until 5% and it shuts down, is it okay if I proceed to charge the phone for 4 hours?

Such an easier process than restoring the whole phone. Here's hoping it works.

That is a very helpful analogy 🙂

I Have been running through full battery for iPhone 6+ in 2-4 hours! Made a GB appt but kept playinv for an answer and here's what I got that fixed it for now:

for the shutting off at 18-19#% problem I did what Lawrence recommended & it worked so far. After it shut off, I plugged in for two min, then took the cable out first, then force rebooted, and when it came back on there was a sudden jump from 20% to 4% to 1% and then I put a movie on silent and ran down that last power which took 2 hours!!! ( so it had more than 1% obviously) and then I plugged it into it wall charger and left it for 4.5 hours.

To solve the rapid drain problem I took over all the setting manually. I turned off most background refresh, took off auto bright, took off everything I could find that seemed optional just to find the issue(there's alot of manual settings, if you don't know go have a deep look into the settings app & see how much you can turn off!!) After two days it was iCloud Drive that was found to be the cause. When I turned off that, the problem went away. Bottom line: the battery status is not the whole story, start turning things off to find out what is causing it!!! It took two days because to isolate variables you can't do everything at once! Ok? Do it piece by piece to see what happens...

OTherwise do do a restore as new or go get a new battery. Neither of those are the end of the world.
