Wi-Fi Assist makes your iPhone more aggressive in jumping off of Wi-Fi and onto 4G LTE.
There are a few exceptions where Wi-Fi Assist won’t work:
- If you’re already data roaming.
- If the app trying to use it is in the background. Basically, it only works for apps that are in the forefront and active.
- Doesn’t work with most third-party apps that download audio, video, or large attachments such as a video app, music streaming service, or an email app that might download big documents or photos.
Why It’s Awesome
Wi-Fi Assist solves this annoying problem in real life: you’re just on the outer edge of terrible Wi-Fi signal, so your iPhone is desperately trying to use Wi-Fi even though it’s too far away to actually go through.
It happens all the time to me when I’m leaving my apartment, just as I’m getting in my car I have just enough Wi-Fi signal for my iPhone to try to use Wi-Fi instead of LTE, but not enough Wi-Fi for anything to actually work. Sometimes I’ve sat for minutes, even driving around the parking lot before my iPhone will connect to the Internet, which is when I need to be playing my Apple Music playlist or navigating. I often resorted to simply turning Wi-Fi off and back on just to get my iPhone to connect to LTE.
Some people don’t like having Wi-Fi assist enabled because it can majorly run up your bill if parts of your house have weak Wi-Fi signal, like this poor kid who ran up a $2,000 cellular data bill. Ouch. Some people even tried to sue Apple because the feature was enabled in the iOS 9 update without customer consent.
How to Enable or Disable Wi-Fi Assist
It’s incredibly easy to enable or disable this feature if you know where to look.
Settings > Cellular > then scroll ALL the way to the bottom, and you’ll see the switch. Green is enabled, grey is disabled.
You can also see how much cellular data your iPhone has used if you have at least updated to iOS 9.3 or later.
What Devices Can Use Wi-Fi Assist?
According to official Apple documentation on Wi-Fi Assist, any device running iOS 9 or later can use Wi-Fi Assist except the following devices:
- iPhone 4s
- iPad 2 (with cellular)
- iPad 3 (with cellular)
- iPad mini 1 (with cellular)
Uh oh! Your iPhone fell in the pool/lake/ocean/bath/washing machine/sink/toilet! What now? Are all of your photos gone? How do I get a new phone?
These are all really important questions. For most people, losing your iPhone for a few days due to water damage is the equivalent of having an arm removed: we rely on them so much these days for everyday communication that it really hurts to be down.
We feel you.
So here’s our best advice on how to get your iPhone fixed and your data restored.
1. Don’t Try to Turn it On
When an iPhone gets wet, the first reaction is to try to turn it on to see if it still works. Please resist the temptation, because trying to turn on the device can work against you. There may be water on the circuit boards inside and it can cause something to get fried!
We want your iPhone to be resurrected too, just don’t try to turn it on.
2. Put it in Rice While You Figure Stuff Out
You may have heard of the ol’ rice trick, and guess what: it actually works a lot of the time. So, our advice is to put your iPhone into a ziplock bag of uncooked, unseasoned rice while you sort out the details. It can’t hurt anything to get it in rice until you’re back online. We’ve actually seen this bring some devices to life!
For maximum effectiveness, it’s best to keep the device in rice for 24+ hours. It takes a while for the rice to suck out the moisture, so give it some time before you try to turn it on again.
3. Don’t Get it Fixed Anywhere but an Apple Store
Even if your iPhone isn’t under warranty, we recommend getting your iPhone repaired by Apple. You can check your warranty by putting in your serial number into this website. If you’re not sure how to find your serial number, go to this site and follow the instructions from Apple.
Apple has the ability to completely replace your device that same day, even if it’s way out of warranty, for a reasonable price. And, if you have a warranty, you could save a ton of money.
Getting your submerged iPhone/iPad fixed anywhere else but Apple will void all of your warranties with Apple and can be extremely costly down the road.
If you can, make a Genius bar appointment at your nearest Apple Store to get a replacement set up. If you can’t make an appointment, Apple has opened up to take more walk-in appointments, so just go up there.
