[最近剛購買的裝置，其預估電池續航力似乎比以往的裝置更短，為什麼？]
[最後更新日期 : 2020年11月25日]
[Gálá~xý Ñó~té9/S9/S~9+ 提供了許多方式增加電池續航力。剛購買使用手機的前幾天（大約三天）由於 應用程式電力監測與最佳化電池用量功能尚未正常運作，您可能會覺得電池續航力較短。]
[依據您的裝置使用習慣，若開啟應用程式電力監測與最佳化電池用量功能增加電池續航力，經過約一週後，裝置便可提供更精確的預估電池續航力。]
[預估電池續航力視您的裝置設定、個人電池用量模式與操作條件而異。]
[建議可透過以下方式增加電池續航力：]

[立即最佳化功能可透過以下方式優化裝置效能：]
[• 釋出記憶體空間]
[• 刪除不需要的檔案並關閉在背景運行的應用程式]
[• 管理異常耗電情形]
[• 掃描偵測惡意軟體與網路釣魚]
[應用程式電力監測]
[避免在背景運行的應用程式耗用電量，以達到省電效果。]
