iOS 17 Low Power Mode Turning Off Automatically: Why It Will Not Stay On

You enable Low Power Mode to stretch the last of a battery, and by the time you look again the icon is yellow no longer. It switched itself off without asking. This behaviour is deliberate rather than a bug, though the logic behind it is not documented anywhere the average person would find it, which is why it feels so rajaong arbitrary.

What Is Likely Causing It

• iOS disables Low Power Mode automatically once the battery charges past 80 percent, on the reasoning that it is no longer needed.
• Plugging in and charging even briefly can push past the threshold and trigger the switch-off.
• A Shortcuts automation created earlier may be toggling it based on a condition you have forgotten.
• A Focus mode with a low power setting may be interacting with the manual toggle.
• Restarting the phone can clear the setting in some situations.

First Steps to Try

1. Note the battery percentage when it turns off. If it is around 80, the behaviour is by design and nothing is wrong.
2. Re-enable it from Settings, Battery, after charging if you want it to continue.
3. Add a Low Power Mode toggle to Control Centre for faster access.
4. Check Shortcuts, Automation, for any personal automation referencing battery level or power.

If the Problem Persists

1. Create your own Shortcuts automation to enable Low Power Mode at a chosen battery percentage, which is the closest thing to making it permanent.
2. Build a second automation triggered when charging ends if you want it to resume after every top-up.
3. Check whether a Focus mode has a low power option enabled and is fighting your manual setting.
4. Restart the phone if the toggle refuses to stay on even at low battery levels, which is not normal.

Safety and Data Warnings

Running permanently in Low Power Mode disables background refresh, some visual effects, and automatic downloads, so understand what you are giving up before automating it around the clock. Do not install third-party apps claiming to force the mode on, since iOS does not expose that control and anything claiming otherwise is misrepresenting itself.

Conclusion

The 80 percent cutoff explains almost every case of Low Power Mode switching itself off, and once you know the number, the behaviour stops being mysterious. A Shortcuts automation is the legitimate way to make it stick on your own terms. If it turns off well below 80 percent, that is genuinely unusual and a restart is the right first response.
