Should You Regularly Restart Your Phone? Here’s the Answer
We're already in 2026, yet some "urban legends" about smartphones still persist. For example, putting a water-damaged phone in a bag of rice—please don't fall for that trick. However, regularly power cycling your phone can actually solve many real-world issues, and in critical moments, it can even act as a privacy guardian.
- Real Performance Benefits of Restarting
Modern phone systems are designed for long-term operation, and cache allows frequently used apps to open instantly. But when memory management reaches a critical point, app crashes or abnormal battery drain can follow:
| System Type | Memory Management Features | Restart Recommendation |
| Android |
| Recommended to restart weekly for noticeable benefits |
| iOS |
| Restart only when experiencing lag |
- Privacy Protection Power Move: BFU State
The biggest "hidden feature" of restarting is related to security. The NSA recommends restarting weekly to defend against some zero-click attacks, but for regular users, the most valuable aspect is the BFU (Before First Unlock) state.
After restarting your phone and before entering your password, the system enters a highly encrypted BFU mode. At this point, encryption keys are not stored in the RAM cache, making it extremely difficult for forensic tools to extract data. Before going through CBP or TSA checks, manually restarting and not unlocking your phone can effectively protect your personal memes (like JD Vance and others) and private data.
There's no need to time your restarts—just do it whenever you feel like it. Brands like Samsung support automatic restart settings, and it's recommended to enable them. iPhones also trigger a protective restart automatically after 72 hours of inactivity. Restarting is more of a troubleshooting tool than a mandatory daily KPI.
(Note: The automatic restart feature mentioned in this article may vary depending on the phone model, system version, and carrier customization. Please refer to your device's actual settings.)
