iOS 11.4リリース直後から、アップデート適用後にバッテリーの消耗が激しくなったという報告が多数上がっているようで、アメリカのApple Comunityでも話題になっています。 iOS 11.4 battery drain My iPhone 6 was working perfectly fine until I updated to iOS 11.4 and ever since I did that my battery is draining rapidly even without me using it at all. I used to go a full day without charging it now it may last half a day. I am just wondering if something got turned on with this
