Iphone Battery Drain Issues

Fuzzy Cumulonimbus Cloud

Hi H/A,

My husband has an iPhone 5S from AT&T. It continuously shuts off at random battery percentages and doesn't seem to hold a charge. We had the battery replaced but it is still not holding any charge. This happens with multiple chargers. Not a charger issue.

Has anyone else had crippling iOS 10 battery problems?

We have tried:
1) Draining to zero percent and charging to full.
2) Resetting settings.

Neither of these two things has fixed it.

Any ideas?

Thanks,

FCC

I'm having them. 5S from tmobile. I'm not sure if it's iOS10 related, so much as shitty hardware related. Mine can't seem to make up its mind on just how much battery percent I have left, even with a new battery.

I did get it to do the drain to zero, power down, and a "soft reset" that kind of worked for like a week.

My iPhone 5S also does this. I've resorted to using a phone case with a built-in battery to provide it with some extra charge when it thinks it's dying (I'm 99% sure that it's not), which adds some bulk, but also greatly prolongs the amount of usage time I get out of it. My understanding was that this was a common problem in 5S, but I'm not sure if there's a solution.

Not sure if this is the same issue I've dealt with. I would have my phone suddenly shut off when it was at 20%, and when attempts are made to turn it back on, it would show the screen indicating insufficient battery power. When I set my phone to 'power saver mode' I have not encountered the issue again - I routinely am able to use my phone even at 1% battery.

However, in my case the battery always showed that it was charging properly. Using 6S.

Agreeing with juicer

I have the 6s and it will randomly turn off anytime it's below like 25%

making sure it's always in low power mode seemed to do the trick, it still turns off sometimes, but not as often..

also the battery just lasts longer so making sure it's in lower power mode seems to be a good idea anyway

Yep, my user base experiences that pretty regularly. We replace 3 or 4 iPhone 5s per month due to what we have determined is "wacky battery", and I expect to continue the trend until they are all gone.

All phones will have similar issues at one one point but the 5s was horrible at this. I don't know why exactly but there were some serious issues with that phone's battery management system. I had replaced the battery on it twice: first replacement after 1.5 years of use, second replacement 1 year after the first replacement. The phone itself died last month, so I no longer care for it but as far as I know, unlike NiMH batteries, Li-Po and Li-Ion batteries should never be left to drain to zero percent. In other words, they don't have the memory effect problem. By draining it to zero, you are actually harming the battery by letting it fall into deep discharge state.

How old is your 5S? I've found that the 5s itself had some pretty silly issues with battery lifespan, but most phones in general will have some portion start to fail within 2-3 years. You can look into replacing the battery itself with a third party model for less than $40, usually, or expect to pay $100-200 at a shop.

We went to a shop and they put in a new battery and said the same thing was happening. May be time to just get a new iPhone. ):

My 6S plus is doing it. It looks like ios 10 is doing this to any non-7 phone.

My 6 does this as well and is really bad about it when it's cold out. It can go from 80% to off in a couple of minutes but the second it's plugged back in, goes back to 80.

My 6 Plus does this as well. I never run into issues when using low power mode, which I was available all the time.
