Iphone 7 Stuck on Low Data Mode

I had a similar problem as you did. Under the WiFi setting there is an i, select that and it allows you to switch in/put of low data mode.

It turned out the WiFi low data mode was also my problem. Thank you!

As I said, low data mode does not slow down your phone, it just prevents high data use functions from using cellular data. You can still use those functions over Wi-Fi; the low data mode switch does not affect Wi-Fi useage. So the fact that your phone is slower is unrelated to low data mode, and is probably because your battery is failing. The phone is designed to slow down when the battery is weak to prevent sudden shutdowns. See—>iPhone Battery and Performance - Apple Support

If you turn it off does the switch stay off? And Low data mode does not slow down data; it disables some functions that use a lot of data like photo sync.

If your phone is slow that’s because the battery is failing.

The solution is to have your battery replaced. It will still sync photos, but only over Wi-Fi. And it will also download app updates, but again, only over Wi-Fi.

Cellular network access is the heaviest user of battery power on the phone after the screen, and if the signal is weak it will even exceed the screen’s drain.

The reason you haven’t have any sudden shutdowns is because iOS slowed down the CPU to prevent sudden shutdowns.

It might be one of the ways it prevents sudden shutdowns. But again, low data mode doesn’t slow down anything, it just stops photos from being synced over cellular data, stops app updates and disables background app refresh. As noted under the setting.

My educated guess is that you can’t turn off low data mode because the battery is failing. If you could turn off low data mode your photos and other content would sync over cellular data, which would probably cause the battery to shut down from the heavy drain of a cellular network connection.

Did you ever find a solution to your “low data mode“ problem, Ciaraj90? I recently sent my phone to Apple for the “No Service” repair and they replaced the battery while they were at it. I got it back and it too is stuck in low data mode. This never happened before I sent it in.

Hi. I too am (was) stuck on low data mode and stumbled across your question.

I found here https://www.reddit.com/r/iOSBeta/comments/dekvxc/bug_hotspot_wifi_cant_disable_low_data_mode_it/ that low data mode is also a setting that can be found in Wi-Fi. Go to Settings / Wi-Fi / then click the info symbol next to your Wi-Fi connection. Scroll down and you will see Low Data Mode. For me, it turned out that this was ON and causing updates to pause until I manually forced the update.

The setting I kept mistakenly going to was in Mobile Data / Mobile Data Options / Low Data Mode. This was OFF, so I couldn’t understand why updates kept telling me Low Data Mode was on.

It doesn’t help that if you go into Settings and use the search bar for Low Data Mode it only shows the one under Mobile Data.

Hope this helps.

Apple considers 80% to be the end of the battery’s useful life. So it forces low power mode to reduce the probability of the phone shutting off unexpectedly. Apple will replace the battery for $49.
