Although just about every iOS update has at least a couple of minor bugs, the iOS 7.1 and 7.1.1 updates have caused some major problems for quite a few iPhone owners. While the iPhone 5S has been the model with the most problems from these updates, other models like the 4S have been impacted as well.

In terms of the specific problems these updates have caused, the four big ones are battery drain, WiFi not working, crashes & data loss, and Touch ID issues. If you have experienced any of these problems with your iPhone, keep reading to get more details on each issue, as well as what you can do to resolve it:

Battery Drain

A thread in Apple’s official support forum has spurred three pages of responses about battery drain issues since the 7.1.1 update. The original poster said he’s had to charge his iPhone 5S two to three times per day since he installed the update. Several subsequent posters said they were experiencing the same problem with their iPhones, as well as one poster who said the update was causing his iPad 4 battery to drain in no time.

If you’re experiencing this problem, the first thing to do is check out this post from Overthought.org. It includes eight different steps for improving the battery life of your Apple device. If you go through those steps and are still experiencing significant battery drain, your best option is to fully back up your phone via iTunes or iCloud. Then once everything is backed up, do a full erase of all data and settings. Several people in the previously referenced thread about this problem said that the full erase solved the problem for their device.

WiFi Not Working

The next most common problem caused by the 7.1.1 update is an iOS device being unable to connect to WiFi. As several people explained in another official support thread, they’re experiencing one of two problems with their WiFi. Either the device won’t stay connected to a network, or it will keep rejecting the connection by saying the password is incorrect even though it’s not.

If you’re having this problem with your home WiFi connection, the first possible solution is to unplug your router and modem. Be sure you actually unplug the cords from the wall, and not just from the back of these devices. After letting them sit unplugged for a few minutes, plug the cords back in and see if this fixed your problem. If the problem persists, the next option is to click the lowercase i with a circle around it next to your network’s name on your iPhone, and then click the Forget this Network option. If that solution doesn’t work either, the other thing to try is the process discussed at the end of the last section of backing up your data and doing a full erase.

Crashes and Data Loss

Mirror Online reported that numerous iPhone 4S, iPhone 5C and iPhone 5S users experienced bricking or data loss after updating to 7.1.1. If this update caused you to lose any data, you may be able to restore it via an iTunes or iCloud backup. If you don’t have a backup with your most recent data, it’s probably going to be impossible to get back anything that was lost. The unfortunate truth is this is a rough way to be reminded that it’s always best to do a full backup before installing any update (even if it’s a minor one). And if you’re unable to turn your phone on at all, you’ll definitely want to get professional help with that problem.

Touch ID Issues

Although Apple said that improving Touch ID was one of the main goals of the 7.1 update, many users have reported that this update actually broke their Touch ID experience. If you’re in the same boat, iMore has published several steps to fix the problem. The two main steps outlined in their post are deleting all your prints from Touch ID and adding them again, and/or restoring your iPhone 5s from a backup. Also, if you haven’t updated to 7.1.1, several posters in this thread reported that solved their problem after experiencing multiple issues with Touch ID and 7.1.
