Battery got significantly worse with iOS 9.0.1

It seems that factory reset and restore my ip6+, the battery seems to behave like it should be. At least for one day that i observe it remains 100% after overnight. And when i texting with social apps, for about 10mins, the percentage drop was about 6%. To me, this is normal. I will continue to observe the battery behavior in coming days. Thanks for the info!

Hi peeps!

I had the same issue after IOS 9 update with my 5S. Tried all different things and finally one worked.

I turned off the cellular data and wifi off before going to sleep. The battery did not drain through out the night and when I connected back to the internet, my phone has started behaving. It's not heating up anymore and the battery usage is normal now.

Let me know if it works for you...

Cheers!

We're having problems with battery drain with both 4S and 5S. Wired suggested going to cellular data, scrolling to the bottom and turning off wifi assist. The 5S has this feature, the 4S does not. I've turned off cellular data on the 4S. We'll see if this makes a difference on either phone. We're used to 2 days of battery on both phones. This is a pain. Wish I'd never done the update.

Me too, I have thought about updating to ios 9.0.1 for a long time now I regret that decision, currently as of right now, my iPhone is plugged in because of having a phone call for about 10 minutes wastes about 20% of your battery. Apple is just going in reverse from their products even to their new ios. Next phone of choice is going to be Android.

SAme problem here. My iphone 6 battery life dropped dramatically after updating to IOS 9. It got worst with 9.01 and 9.02. Bad work Apple. It worked perfectly with IOS 8.4.1. Fix it or I will switch to Android.

Inot sure what happened but since my last post everything turned around. I didn't change anything. It's a mystery to me but I love my phone again.

I Have to say that, after the 9.0.2 update and a few app updates, things seem to be back to normal with regard to battery life. I'd be interested in hearing others' experiences.

No luck here - I'm still getting the hard crash when using the Sleep Cycles app after a couple of hours, might just need to wait for them to update.

I upgraded my 5s from 7.1.2. Previously it goes 2+ days with a charge, now it's hard to pass 1 day with light using.

Apple is evil.

Same

hi, noticed the same batt drain on my 5s. full charge in the morning, batt gone flat in the evening i was whatsapping n stuff during the day so at first i thought it was prob cuz of that. but i put my full charged 5s on airplane mode before sleep, the batt gone flat the next morning. clearly the batt drain even its on airplane mode. wish i'd nvr done the update. 😟

Don't know if I'm glad to see that I'm not the only one, but wow, everyone! Same here, iPhone 6 and iPad mini both destroyed by the last two updates, first to go has been battery life on both, but also, slowwwww like never before, and everything keeps crashing! Was hoping to avoid factory reset, since it has not resolve things for everyone, so I sure hope Apple steps up for its customers, soon!!! These devices aren't only for luxury use anymore, they're necessities!

Mine actually seems to last longer after upgrading from 8.41 to 9.01, I haven't upgraded to 9.02 yet.

iOS 9 is terrible - since the upgrade, battery life is ZILCH. Can't get through a day! It is chewing up everything, running down th phone in less than one day. Something is very remiss with this OS. Very bad programming internally, very bad power management, very bad systems programming. This entire system needs to be reworked to resolve such disastrous issue. I severely regret this upgrade!!! There are some bad problems, I suspect way into the kernel of the OS.

Yikes, I really hope this gets fixed because I don't even know how to go back.

IT is a problemas about the battery life after update to IOS9, but mainly about the battery percentage counter. It workd terrible. Fix it Apple
