Loose battery connection or bad battery, faulty iOS update, and unsuccessful jailbreak are some of the common causes of boot loop problems affecting various iPhone models including the iPhone 7.
There are two symptoms of boot loops problems in iPhones. First, is when your iPhone restarts intermittently and second is when your iPhone is stuck in a restart loop. With the first symptom, you may still be able to use your iPhone for a while without bumping into an issue but then it suddenly restarts. With the second symptom, it’s going to be worse because your iPhone continuously restarts and therefore not usable. What usually happens in the second scenario is that you’ll likely to see the Apple logo on your iPhone display for a few seconds and then suddenly disappears and it reiterates.

Potential solutions to iPhone 7 infinite restarts or boot loops
These subsequent procedures are typically used when dealing with more intricate software errors on the iPhone. They’re regarded as tough solutions for tougher bugs. You have to note though that both these procedures will delete all your critical data including personal information saved in the internal memory of your iPhone 7.

In this method, you’ll need to enter recovery mode first and then select the option to restore iOS. You may opt to restore your device to a previous iOS backup that more stable or restore your iPhone to factory defaults.
A lot of complex software issues are rectified by recovery mode restore in both Android and iOS devices. Nonetheless, some problems may be just tough enough to withstand and manage to persists after the procedure.

If a recovery mode restore failed to fix the problem, then your next possible solution is a DFU or Device Firmware Update mode restore.

Again you will need to use iTunes on a computer to carry out this restore.
You may refer to our comprehensive walkthroughs on how to perform a recovery mode restore and DFU mode restore on iPhone 7 available on our dedicated Troubleshooting page for iPhone 7 under Tutorials section.
- Use iOS repair/recovery software. Seeing the rising number of iOS device owners who encountered more intricate software problems including infinite boot loops, more and more iOS recovery and repair tools are being developed and rolled out by software companies and developers. While not all of these tools guarantee a sure fix, it won’t hurt to try. Some people who have used similar software before ended up with some success. Should you wish to give it a shot, just do some Google searching of these software. You may opt for a free version or paid version of your preferred software.
- Remove and reinsert SIM card. It is possible that the problem has something to do with a bad SIM card since SIM card connects your device to your wireless carrier. If there’s a problem with your phone’s connection to your wireless carrier, there’s a tendency that your device can get stuck in a restart loop. To rule this out from the possible causes, you may try to remove the SIM card from your iPhone 7. If the problem doesn’t occur with the SIM card removed, then you’ll need to fix SIM card issue first. You may try to restore iOS in iTunes or have your SIM card replaced in this case.
- Pay for service or avail for warranty. Should this be a system glitch that comes along with the pre-installed apps and services on your device and you couldn’t get it fixed no matter how hard you try, then take a trip to an Apple service center for further assessment. If eligible, don’t forget to avail for service warranty or unit replacement. If you just bought this phone then you should be eligible for warranties. Otherwise, you will really have to pay for service.
I won’t recommend removing the battery from your iPhone 7 because it’s risky. Instead just let the Apple technician do it for you.
