iOS 7 battery life fix with clean install


There are plenty of iOS device users happily using iOS 7 since the recent update, but it seems many users are still having problems. There are still issues for some iPhone 5 and 4S owners regarding faster battery drain on their handset since the update, so today we want to give you information about an iOS 7 battery life fix from a clean install.

We recently discussed the battery life hit for some iPhone users that seems to have been caused by the iOS 7 update. Many readers responded to this article with comments to say that their device was suffering severe battery drain since the update, with plenty wishing they’d never updated at all because of this.

However, there’s good news on the horizon as it appears that this problem may not be as bad as we initially thought and can be fixed pretty simply. One site suggests that any such problems with battery life in the majority of cases, is only because of the installation process.

We’re informed that in most cases the battery drain that some iPhone users are noticing can be fixed with a clean install, after backing up the device first of course. If the battery life on your iPhone was fine before iOS 7, then the chances are that this is purely a software issue and performing a clean install is all that’s needed.

However, it’s also acknowledged that there may be some cases where the battery is faulty at hardware level and in these instances a clean install will not work. Product Reviews notes that they tested iOS 7 in beta stages and on the final public release. Whenever battery life issues were encountered, a clean install after backing up was all that was necessary to rectify the problem.

If you’re not sure how to perform a clean install on your iPhone you can find further instructions here. This issue seems to be mostly affecting the iPhone 5 and iPhone 4S, although there are also cases of people complaining about the battery life of the just-released iPhone 5S that of course was released running iOS 7.

We’d like to hear from readers about this, so please feel free to send us your comments. Are you one of the many people who have noticed that the battery life of their iPhone 5 or 4S has been detrimentally affected by the iOS 7 update? If this is the case and you now decide to perform a clean install, did it solve the problem for you?

    I have an iPhone 5 and the battery life was dreadful on iOS6, however I did a clean upgrade and re-synced everything whilst not the best it has improved a fair bit from before the upgrade.

    Please keep writing about this until Apple addresses the issue. Think you are right that this is a software installation issue that must have introduced some kind of bug or hangup. That is why it is affecting many but not all iPhones. My husband and I uprgraded our 4S phones exactly the same time to iOS 7 two days ago. Mine upgraded quickly, installed quickly, and I have had zero problems and no battery issues at all. My husband’s installation was very slow, took about 15 minutes longer than mine — and since then his battery has been draining in about 4 hours. It looks from usage data that his phone has been doing something every second. Not sure what it is but whatever it is, it is bad. This morning we charged both phones to 100% We left everything switched on on my phone. We turned off background app refresh and everything else we could think of on his phone. Four hours later, his battery was drained to near zero. 8 hours later, my battery is still near 90%.
    We will try a clean install on his phone tonight.

    I did a clean install yesterday and that fixed the issue perfectly but once that battery cycle ran out, I’m back to the same issue! Notifications, wifi, bluetooth, app refresh, brightness, push emails are all off and I’m loosing 15-20% every 2 hours when idle!!

    Had the same issue for days; however, just before noon today I needed to charge my iPhone 5. The only thing i had available was my iPad charger, I fully charged my phone…it’s been 4 hours and i’ve hardly used over 15%. i chalked it up to the charger, not the phone.

    I updated three iPhone 4S to iOS 7 and all have experienced much higher battery drain. On two of the devices I did a clean install via DFU and then restored from backup, and that didn’t help. I’ve disabled background processing, 3D effects, etc. and it hasn’t helped. It’s hard to tell what’s consuming battery power, but it seems like using the readio (either wifi or 3G) is a culprit.

    I could get a day of fairly heavy use on iOS 6, but now I can barely get through half a day. This is very annoying, and even more annoying is that Applr doesn’t allow users to go back to iOS 6. I hope they fix this soon.

    OK, back to update report from yesterday. Intrigued by reading elsewhere that perhaps the phone was updating or doing something when ios7 was installed and it was caught in a constant effort to keep doing that. So short of a clean install, I did these things in this order to fix the battery drain: 1) turned off wifi. 2) swiped apps so all are off 3) held down the home button and on-off switch until the picture of the apple came on (showing reset), let go and let it reboot. 4) plugged in phone 5) turned wifi back on 6) went into settings – icloud and backed up the phone. it took an age. 6) turn phone off and back on. When I had finished all those things, I unplugged the fully charged phone and let the phone sit overnight. This morning it still had 95% power. Perhaps one of your readers or staff can figure out which one of these steps solved the issue and report back if it works for them as well.
    Good luck to all.
