Performance
When you have many history items, a lower-end device, or want steadier background behavior, tune with this page. The core idea: record less junk, control history size, and trim unnecessary background and sync overhead.
Who this is for
- Users with slow list loading or high resource usage
- Users on low-end devices, or who want lighter, steadier background behavior
Locate the bottleneck first
| Symptom | Tune first |
|---|---|
| History list loads/scrolls slowly | History size: cleanup + retention + dedup |
| Lots of useless content recorded | Sources and filters: disable unneeded sources, add filter rules |
| High background usage or battery drain | Background/power policy and sync scope |
| Stutters during sync | Sync method and sync scope |
Tuning actions
Lower the retention capacity, set retention days, and enable dedup. For how-to, see Delete, cleanup, and retention; for settings, see Settings.
Disable clip sources you don't need, and configure History filter rules so useless or sensitive content never enters history.
Sync only what needs to cross devices; avoid pulling large amounts of local content into sync. For method choice, see Sync overview.
Pick a lighter mode in the performance/background settings (item names follow the app). When you need stable background behavior, keep the necessary background permissions.
Image and file clips cost more than plain text. When handling large content often, pair it with a cleanup strategy to keep the total down.
Values like history capacity and retention days vary by version and settings [待确认：current version defaults and limits]. Defer to the actual items in Settings.
How to verify after tuning
- After cleanup or narrowing config, reopen clip history and check that loading and scrolling feel smoother.
- Use it for a while and confirm background usage and battery return to an acceptable range.
