iPhone 4S - iOS 8 battery issues

Hi there Drumrocker365,

You might take a look at Settings - General - Usage - Battery Usage. That screen should show you which apps are using your battery. I found that the Moves App was using the majority of my phones battery.

HTH

I suffer the same issue with an iPhone 5. Normally at the evening it had about 70% left, now it's about 25%... I'm really annoyed about this.

I'm having the same issue with the battery life, it's terrible!!!!

I Was hoping they fixed it in iOS 8.0.2 but no. Hopefully they do something soon because I really need my battery life back!!!

Exact same issue here, so are a lot of people. Battery goes down at 10% per hour while the device is on Standby. IOS 8 has taking the mobile out of mobile phone. The 'improve battery tips' do very little. All I'm looking for is a chance to downgrade to 7.1.2. I missed the window.

I have the same problem with my beloved iPhone 4s on which I installed iOS8. It use to last almost one day, not it doesn't last even 8 hours (mostly on standby): at lunchtime, I have to recharge it again.

No app background update, limited GPS location, no e-mail push, new battery just installed, etc... But if I cannot use these things on a smartphone, then I just go back to an old Nokia brick... Frustrated...

Does anybody knows if 8.1 or another update will possibly address this issue?

I am having the same problem. I had it in standby when I started work and the battery was about 85%, didn't use the phone all day, by the time I left 8hrs later the phone was dead. I have seen no real advantages from updating to iOS 8.

After installing iOs 8 I'm starting to hate my smartphone. With Ios 7 the battery lasted until the evening while now barely reaches mid-afternoon with the same use of the phone and being careful not to leave apps in the background. I'm afraid to use the smartphone to save battery power ... frustrating!!

I ask Apple to release as soon as possible an upgrade to fix all the problems with iphone 4s or enable us to return to IOS 7.

Despite updating to 8.0.2, my iPhone 4S still only last for about 6 hours.

Will 8.1 fix this?

No, it did not. 8.1 still ***** battery life.

Apple is definitely not the same company under Tim as it was under Steve. The IOS 8 update is on par with Microsoft updates causing tons of issues for customers. As someone who's used Apple products for 20 years it makes me sad to see them falling from grace with these kind of update bugs.

I have the iPhone 4S -- come on! it's only 2 years old! -- and the running app I was using, LogYourRun, was brought to its knees after the IOS 8 upgrade, I scoured the internet for solutions. They all said just about the same thing -- try restoring your iPhone from backup, shutting off unnecessary Location Services, getting a new battery, upgrading to iPhone 6, putting the phone in Airplane Mode (um, that's not going to work if you want to receive phone calls or use an app that is dependent on GPS...), etc. The problem is that about a mile into my run -- regardless of how much battery juice I had when I started -- the phone died and trying to restart it showed only the momentary red battery graphic (i.e., you're toast). After returning home and plugging it into the charger, it would reboot and show 40-50% battery life remaining. I wrote to LogYourRun Support. I wrote to Apple Support. I trolled all the blogs and forums. I gave up waiting, and downloaded the MapMyRun app and the RunKeeper app and tried them out. Guess what? SAME EXACT PROBLEM. It's actually worse with MapMyRun because every 2 seconds they treat you with a new ad that you have to dismiss in order to see your split times. Well, after hours more of trolling the internet I stumbled across a post that identified an IOS 8 bug with Location Services and use of WiFi. Using WiFi does supposedly improve GPS tracking performance. Last night, I shut it off and did my normal 5K loop (all other Location Services except LogYourRun shut off as well), and, voila!, no battery drain at all. The route tracking, timekeeping, and all other functions worked as accurately as they had in the past.So, if you're not actually using WiFi, try shutting it off and see what happens to your battery life. Hopefully, Apple will fix the bug in the next update (I have the latest 8.1.2 version, but the problem started with the first IOS 8 upgrade -- it wasn't a problem under IOS 7).

I just need to share my solution to a similar problem with my 4S in hopes that it may help someone with the same problem. It may not be what OP needs to solve his, but worked in my situation. I was banging my head against the wall in what seem to be TERRIBLE battery life with IOS 8 and my 4S. I tryed all of the usual suggestions with turning of notifications, background refresh, etc. No luck. I tried a new battery. No luck. In troubleshooting some more I realized my phone would not turn off. After turning it off, it would turn itself back on. I did some research and a lot of folks seemed to point to the dock connector. I switch out the dock connector, and my phone then did turn off. I then charged it to full and did a usage test and found it had maintained its full battery life with a long standby time and showed 0 usage. My phone now stays in the 90% with minimal use through the day. Before the dock connector replacement, my phone wouldn't make it through the night on a full charge in airplane mode. Thank God, I was really starting to get frustrated and lose my senses. I think it was a coincidence that happened to fall close to the IOS 8 update, but I was very quick to blame IOS8. Did not turn out to be the issue once I breathed a little and tryed a better troubleshshooting approach. Hope this might help someone searching with the same problem.
