iPhone suddenly power hungry

Other Apple Chat

I have a 2 year old iPhone 5s that up until recently never gave me any trouble.

In the past I've always been able to go 2 or 3 days before needing to recharge the battery. About a week ago it started getting power hungry to the point that I now have to recharge it every night.

I've checked the settings and they all appear to be unchanged from where they were before.

I usually close all running apps when I am done using the phone for a while, so I don't think it's apps in the background consuming power.

In case it matters, I'm running iOS 8.4.1.

Could my battery be dieing?

There has been quite a bit of commentary of late regarding the Facebook App sucking huge amounts of battery life. It was recently reported that in some cases there was up to 57 minutes of unexplained background activity for every 21 minutes of use.


This may or may not be the cause of your problem, but if it was my phone I would rather isolate an App issue before taking action on a failing battery.

hi, yes, if it's not an app like facebook draining it, location services being activated in the background, something you might want to check for, or something along those lines, yes, the battery could be having problems maintaining a full charge as it used to. on average, most phone batteries are only rated for a life span of about 2 years. so there is a good chance that yours is giving up bit by bit. if you have an apple store near by, you could take it in, and get them to check it. if it's the battery, you can have a replacement battery done for, i think, $100 USD

I don't do any of the social sites like facebook or twitter. Internet forums like this one are the closest I come to them. So I have never launched the facebook app and would have gladly deleted it if that was allowed.

Wow! $100 for a battery? That's &$*@)$* insane!

Could be worse. Also, take into account that they are replacing old battery with the said new battery. Also, if you can, fid a local batteries plus bulbs store near you. They do phone battery replacements, and usually have them done same day or day after. I just replaced my battery on my 5S this past september and paid around $60 for it, so it's well worth the cost of getting a new battery and having the store replace it.
Yeah, your battery is going. I had my old battery in the 5S for about 2 years actually and noticed that over time, the battery just wouldn't go for more than a day, and it would randomly die at like 28% charge and or sit at like 70% and drop in the blink of an eye to 1%. I once had the phone refuse to turn on for 20 minutes due to the battery being crap. Eventually hooking it up to a power pack for 25-30 minutes did the trick and it started charging and booted up.
HTH and good luck

Hi. Yep, definitely see if there's a place near you that repairs and replaces Apple products. Luckily for me, I have 2 in my area and their prices are both pretty good. The Apple store is always going to make you pay full price, and to me at least, their prices for almost everything are insanely high. This is why I recommend going other places, so you can save cash.

Before rplacing the battery, try discharging and recharging your phone. I’ve notice plenty of quick battery discharge occurs because the battery and OS are out of sync.

Keep using your phone until it turns off. Turn it back on and keep using it until it turns off again. Repeat until the phone no longer turns on. Charge your phone overnight. Repeat once more.

If this doesn’t work for you, then consider replacing the battery.

HTH and good luck.
