Restart vs. reset: what is the difference?
Understand restarting, power cycling, resetting settings, and factory resetting before choosing a troubleshooting step.
A restart is the least disruptive option
Restarting closes the operating system, clears temporary working memory, and starts the software again. It can resolve a frozen app, temporary network problem, stalled update, or process that is using too many resources.
A normal restart should preserve saved photos, documents, apps, accounts, and settings. Unsaved work in open apps can still be lost, so save what you can before restarting.
A power cycle fully removes power
Power cycling means turning equipment off, removing its power source when appropriate, waiting briefly, and powering it on again. This is common for routers, modems, televisions, and accessories that do not have a useful restart command.
Use the manufacturer’s procedure for devices with batteries, storage activity, medical functions, or other special shutdown requirements.
Not every reset erases the entire device
Some menus offer targeted resets for network settings, keyboard dictionaries, preferences, or app permissions. These can remove the named settings without deleting every personal file, but they can still disconnect networks or undo important configuration.
Read the confirmation screen closely. The exact meaning of reset depends on the device and the option selected.
A factory reset is a major step
A factory reset is designed to erase user information and return software settings close to their initial state. It is useful before selling a device or when serious software problems remain after safer troubleshooting, but it should not be the first response to a minor issue.
Before proceeding, confirm that important information is backed up, that you know the account credentials needed for activation, and that any security or device-protection feature is handled correctly. Keep the device connected to reliable power during the process.
- Save and back up important files.
- Confirm account passwords and recovery access.
- Check whether authenticator or wallet data needs a special transfer process.
- Follow the manufacturer’s instructions for the exact model.
Frequently asked questions
Will restarting delete my photos?
A normal restart should not delete saved photos or other personal files, though unsaved work can be lost.
Does a factory reset remove everything?
It is intended to erase personal data and settings, but the exact scope varies. Verify backups and follow the device manufacturer’s instructions.
Should I restart my router or reset it?
Restart or power-cycle it first. A factory reset removes its customized network settings and usually requires complete setup again.
