After updating to iOS 20, affected users are seeing battery drops of 25–40% within just a few hours of light usage. The issue appears even when phones are mostly idle. Background activity, push notifications and location services seem to be consuming abnormal amounts of power.
Some users also report noticeable device heating during simple tasks like messaging or browsing, suggesting deeper system-level background processes running unchecked.
Who is affected?
- iPhone 15, 15 Plus, 15 Pro, 15 Pro Max
- iPhone 16 series (all models)
- Devices updated to iOS 20 within the last 24–48 hours
- Users across Europe, North America and Asia
Is there an official response?
As of now, Apple has not issued any public statement acknowledging the battery drain issue. Apple Support pages remain unchanged, and no iOS 20 hotfix has been announced at the time of publication.
What should users do right now?
- Enable Low Power Mode immediately to limit background activity.
- Disable Background App Refresh for non-essential apps.
- Limit location services to “While Using” only.
- Avoid full factory resets until Apple confirms the root cause.
- Wait for the first iOS 20.x hotfix which is likely to address performance issues.
