、電池的本身特性，或者說是電的特性。即電池在正負極接通的情況下，就會產生耗電行為。因為手機電池接有保護板，內部是形成迴路了的，而電子無器件是需要耗電的，否則無法工作。
手機在待機狀態下，後臺程序，移動信號，手機內元器件也是一直處在工作狀態的，因此會一直耗電。比如你什麼都開著視頻呀流量呀其他的硬件升級後導致耗電增快的。所以最好是晚上什麼都不要開全部關閉就OK了
有些功能增軟件也會會導致耗電快。
啟動多任務同時運行。不要給電池過度充電，電池容易膨脹，膨脹的電池當然會很危險。
電量儘量在20%-40％以上時就給手機充電，如果降到太低，要想給電池充滿需要電池內部發生很多化學反應，會損傷電池或者導致電池膨脹。充電器儘量用原裝的，充電寶能不能儘量不要使用。手機電池最好在常溫下使用，不要邊充電邊玩手機，比如玩遊戲看電視都對手機壽命不好而且還很危險，
還需要經常關閉一些沒必要的後臺應用和服務，比如視頻，微信，藍牙、WiFi問他亂七八糟的軟件。

手機電量會少的原因有很多。
情況一般是手機後臺在作祟，
鎖屏狀態耗電快很有可能是手機後臺沒有關閉或者是自己啟動導致的，
建議您睡前把手機所有應用後臺都關閉（開飛行模式也有利於省電）
當然也有可能是系統問題，您可以升級或者降級系統，或者先備份再格式化。
最後也有可能是電池問題，手機使用兩年左右電池就應該更換了，
重度使用的話一年就應該更換了
希望我的回答對您有幫助，謝謝！
1.你看下手機設置後臺運行軟件是否都打開了沒關
2.還有各軟件推送信息打開了沒有關這些都會比較耗電的
3.另外還有手機電池，主板也會引起一些耗電。
4.這手機待機也會耗一些電
5.待機也會耗電的
6.你關機了手機照樣也會耗電
7.不管那一款手機它都會耗電
8.建議買個諾基亞老年版本的，這個手機省電，充一次電可以用三四天。想省電的話可以考慮一下換這個!謝謝邀請，下期在會!拜拜!
