Why Your Device is Crawling: The Science of Slowdown
Understanding why your device slows down is the first step toward fixing it. Contrary to popular belief, age itself isn't the primary culprit. These are the actual factors responsible for degraded performance:
- Storage congestion: As your storage fills up, devices struggle to find space for temporary files and system operations, causing everything to slow down.
- Background processes: Apps running in the background consume valuable resources even when you're not using them.
- Fragmented data: Files become scattered across your storage, requiring more time to access and process.
- Startup bloat: Programs set to automatically launch during startup create bottlenecks when turning on your device.
- Update deficits: Missing system updates often means you're missing crucial performance optimizations.
- Cache congestion: Browsers and apps store temporary files that accumulate over time, creating digital clutter.
Most importantly, these factors are largely reversible. The solutions outlined below address each of these issues systematically, delivering a comprehensive performance recovery.

Frequently Asked Questions
It depends on the device. On computers, closing unused applications definitely frees up resources. On iOS, the system manages app suspension efficiently, so manually closing apps usually doesn't help and can sometimes hurt performance by forcing a cold start later. On Android, closing resource-intensive apps can help, but modern versions handle background processes better than older versions.
Most "speed booster" apps provide little benefit beyond what you can achieve with built-in tools, and many include advertisements or questionable features. Some perform basic tasks like clearing cache files, but these functions are already available in your device settings. Instead of these apps, use the specific techniques in this guide for better results.
With proper maintenance and occasional hardware upgrades (when possible), most computers can remain useful for 5-7 years. Smartphones typically remain viable for 3-5 years, though battery replacement at the 2-3 year mark often extends their useful life. The techniques in this guide can significantly extend these timeframes, especially for devices used for standard productivity, browsing, and media consumption.
For computers with upgradeable components, RAM and SSD upgrades often deliver the biggest performance improvement per dollar spent. A 5-year-old computer with upgraded RAM and an SSD can often perform equivalently to a much newer model for basic tasks. For smartphones and tablets, which typically can't have their RAM or storage upgraded, focus on software optimization and consider battery replacement instead.
For computers with mechanical hard drives, replacing the drive with an SSD delivers the most dramatic performance improvement. For devices with SSDs already installed or non-upgradeable devices like smartphones, a factory reset followed by selective app installation often provides the most significant speed boost. In both cases, combining these approaches with the maintenance habits outlined above will maintain that performance over time.
