作為app開(kāi)發(fā)者，或許很少有人會(huì)注意app對(duì)電量的損耗，但是用戶(hù)對(duì)電量可是很敏感的，app做好電量損耗的優(yōu)化會(huì)為自己的app加分不少。
如果是一個(gè)好的負(fù)責(zé)任的開(kāi)發(fā)者，就應(yīng)該限制app對(duì)電量的影響，當(dāng)沒(méi)有網(wǎng)絡(luò)連接的時(shí)候，禁用后臺(tái)服務(wù)更新，當(dāng)電池電量低的時(shí)候減少更新的頻率，確保自己的app對(duì)電池的影響降到最低。當(dāng)電池充電或者電量比較飽和時(shí)，可以最大限度的發(fā)揮app的刷新率

不斷的檢測(cè)電量也會(huì)影響電池的使用時(shí)間，我們可以這樣做 |

<receiver android:name=".BatteryLevelReceiver"> |
3 |
<action android:name="android.intent.action.ACTION_BATTERY_LOW"/> <action android:name="android.intent.action.ACTION_BATTERY_OKAY"/> </intent-filter> |
當(dāng)電量低或者滿(mǎn)時(shí)會(huì)觸發(fā)
有時(shí)間再寫(xiě)確定和監(jiān)測(cè)連接狀態(tài)
