Why Does iPhone SE Restart Every 3 Minutes?
Before we get into the details of why an iPhone SE restarts every 3 minutes and how you can fix it, check the table below for some of the common reasons and their solution.
| Reason | Solution |
| Degraded Battery | Replace the Battery |
| Hardware Issue | Repair the Board Issues |
| Software Issue | Force Restart the iPhone |
| Improper Software Update | Update through iTunes/Finder, DFU Restore |
| Not Enough Storage | Free Up Space |
Software Issue:
Common software glitches can lead to the iPhone SE to restart every 3 minutes. Don’t worry though, it isn’t that big of an issue. To fix it, you just need to force restart the phone.
Solution: Force Restart iPhone SE
Following are the steps for force restarting the iPhone SE
Step 1: Press and quickly release the volume up button
Step 2: Press and quickly release the volume down button
Step 3: Press and hold the side button
Step 4: As soon as the Apple side logo appears release the side button
With a forced restart, most of the software-related problems will be gone. But if the restarting problem persists then it is a hardware issue.
Degraded Battery:
If you find that your iPhone is not showing a percentage at the top of the screen then it indicates a battery problem. More specifically it implies that the battery data is not being properly read by the device. This is leading your device to restart every 3 minutes.
Solution: Replace Battery
Before you try to replace the battery, make sure to diagnose and verify that your battery is defective.

Following are the steps to diagnose the battery
- Go to ‘Settings’
- Next, click on ‘Privacy’ and then ‘Analytics and Improvements’
- After that, click ‘Analytics Data’ and then scroll down until you reach files starting with ‘panic-full’
Once you get to the files, keep searching for the keywords where it says ‘Missing Sensor TG0B or TG0V”. If you find any keyword as such then your battery is defective.
Now, you need to replace the battery. Following are the steps for replacing a battery in the iPhone SE
Step 1: Turn off the phone and remove the required screws
Step 2: Use tools like a suction cup or an opening pick to separate the display assembly carefully
Step 3: Disconnect the battery connectors
Step 4: Remove parts like the Taptic Engine, and logic board so that you can access the battery
Step 5: Gently pull away the battery adhesive tab from the battery and then extract the old battery properly.
Step 6: Install the new battery in the battery compartment and reconnect the battery connector
Step 7: Reassemble all the parts

Once you have properly set the battery in your iPhone, make sure to follow the required steps to make the battery life in your iPhone longer.
Hardware Issue:
Apart from the battery, problems in other components such as the sensor or power jack can also lead to the iPhone restarting every 3 minutes.
If there is any defective or missing sensor in parts like the lightning connector flex cable then the iPhone kernel panics will be triggered. This can lead to the device restarting at regular intervals.
Apart from this if the screen or power jack has not been replaced properly then there can be a faulty replacement part. This can mean that the iPhone SE will not be charged properly or the screen will not work properly. Either way, the result is that the iPhone will restart every 3 minutes.
Solution: Repair the Board Issues
Once again, start by diagnosing the issue at first.
- Test with a known good screen.
- Diode Mode the LCD connector line: SPI_AP_TO_TOUCH_CS_CONN_L.
- If OL, there’s a board issue.
- If 0.366, apply pressure on the SIM Tray area to check for fluctuations. Fluctuations indicate a board issue.
You can also do the following
- Check the panic log to identify the cause of restarting.
- If “Missing Sensors: mic1”, test with a known good charging port flex.
- Use high-quality parts, ideally OEM Pull or Premium.
- Diode Mode the Charging Port connector lines: I2C1_AP_SCL, I2C1_AP_SDA.
- OL reading indicates a board issue.
- 0.329 reading indicates no issue, but apply pressure on the SIM tray area to check for fluctuations.
Following are the steps for repairing
To fix board issues:
- Run 3 long jumpers to bypass and reinforce connections.
- Recommended to run all 3 jumpers regardless of symptoms.
- Jumper 1: SPI_AP_TO_TOUCH_CS_CONN_L – Run from LCD connector at C5770 to a trace near SIM tray and U3600.
- Use Boardview software to locate the trace. Once installed, UV mask the jumper wire.
- Jumper 2: I2C1_AP_SCL – Run from R6610 (next to CPU) to C6456 (next to charging port FPC).
- Jumper 3: I2C1_AP_SDA – Run from R6611 (next to CPU) to C6466 (next to charging port FPC).
After installing jumpers:
- Verify Diode Mode readings are no longer OL or shorted (0.000).
- Test with known good parts.
- Check touch functionality and run the stopwatch to ensure the issue is resolved if it surpasses the 3-minute mark.
After fixing, make sure to get a proper power jack for your iPhone.
Not Enough Storage:
When your iPhone SE’s storage is full, it can cause problems. This might make your phone restart unexpectedly and slow down its performance.
Solution: Free up Storage
If the storage has been full for a while then free it up. It is always a good idea to keep some space in your device’s storage. This can allow your iPhone to regularly update itself and avoid problems such as restarting every 3 minutes.
Overheating:
When the device gets too hot, the iPhone can restart itself as a default mechanism. To avoid this issue from happening do not expose your phone to direct sunlight. Apart from that, do not keep it in your pocket for a long time. Keep it at room temperature.
Improper Software Update:
If the software update is not complete or if it fails abruptly then the iPhone SE will restart every 3 minutes.

Solution 1: Update through iTunes/Finder
You have to update the software properly on your iPhone. But you can also do it using your computer.
If you’ve got a computer, you can try updating your iPhone using iTunes (for Windows or macOS Mojave and earlier) or Finder (for macOS Catalina and newer). Sometimes, this can help skip over any problems that are stopping the update from happening directly on the device.
Solution 2: DFU Restore
If you’ve tried everything else and nothing’s working, there’s one more thing you can do. It’s called putting your iPhone into DFU (Device Firmware Update) mode and restoring it. This gives your iPhone a fresh start by erasing everything and installing the newest iOS version.
But here’s the catch: it wipes out all your data, so only do it if you’ve recently backed up your iPhone.
However, before you try to put your iPhone into DFU, you can call Apple Support or visit any of the nearby Apple Stores. They should be able to help you with any of the issues and properly diagnose to find out what can be the solution.
