New iOS 18 Update is Causing iPhones’ Batteries to Die Quickly

iPhone users are reporting that they have to face battery drain issues after the new iOS update on the iPhones. Some iPhone users have noticed a considerable drop in battery life after upgrading to iOS 18. Many reports suggest losing 20% to 30% of battery within an hour of regular use, a sharp decline compared to previous versions.

This problem is especially frustrating since iPhones still lack fast charging features when compared to similarly priced Android devices. Most Android phones in this range offer faster recharging speeds, but iPhone users still rely on overnight charging to achieve a complete charge.

Apple has provided steps to address this issue, helping users improve their phone’s battery life. If you’re using the iOS 18 beta version, some battery performance issues are expected, and previous testers reported similar problems. Beta versions often run background diagnostics and system optimization processes, provoking the battery to drain more quickly.

Apple Support advises that, after an update, background functions continue to work, which can affect both battery and thermal performance. These tasks can temporarily use more energy until they are complete, which may take a few days depending on usage habits.

If you experience battery drain after installing iOS 18, Apple suggests allowing a few days for the system to optimize. During this period, your phone will stabilize, and battery performance should return to normal.

To reduce battery drain in the meantime, try these methods:

•  Activate Low Power Mode to disable non-essential background features like app refresh, notifications, and visual effects, conserving energy.
•  Whenever possible, connect to Wi-Fi instead of relying on cellular data, as it consumes less battery.
•  Review app permissions to restrict apps from using background location services, which can consume power unnecessarily.
• Enable Auto-Brightness or Auto-Lock to prevent excessive screen usage when idle.
