Local notifications have minimal impact on frame rate and memory because they run outside the main UI thread. They do not affect battery significantly if used sparingly. However, frequent or complex notifications with images or sounds can increase battery use slightly.
Schedule notifications efficiently by batching them when possible. Avoid heavy payloads like large images or long sounds. Use lightweight notification content to keep the app responsive. Cancel unnecessary notifications to reduce system load.
Adding local notification support usually adds a small library (~1-3MB) to your app bundle. This has a minor effect on startup time. Keep notification assets small and minimal to avoid increasing app size.
iOS requires user permission to show notifications and supports rich notifications with images and actions. Android also requires permission on newer versions and supports notification channels for grouping. Android allows more customization of notification appearance and behavior.
Your app takes 5 seconds to load this screen. What's likely wrong?
Answer: You might be scheduling or loading notifications synchronously on the main thread, blocking UI rendering. Move notification setup to background tasks or initialize lazily.
