Apple iPad Pro and iPad Air battery drains too quickly

Apple iPad Pro and iPad Air (M4 Pro and M2 Air, 11 and 13 inch) battery drains too quickly: recent update/indexing, screen/radio use, background activity, signal and battery condition should be measured before replacement. Scoped to M4 iPad Pro and M2 iPad Air, 11 and 13 inch.

An iPad Pro M4 normally loses about 4 to 6 percent over eight hours of overnight standby. Losing much more means an app is working in the background or the iPad is still indexing after an update. Turn on Low Power Mode at bedtime and compare the overnight loss; if Low Power Mode makes a big difference, check Battery in Settings for the apps using the most and limit their Background App Refresh.

Model-specific

What is true of this model and not of its siblings

The XDR display
The 13-inch Ultra Retina XDR display is bright and large, so screen-on time is the main drain; lowering brightness gives the biggest gain.
Low Power Mode at bedtime
Owners automate Low Power Mode at bedtime with a Shortcut and say it improves standby drain noticeably.
Other models this page answers
These steps also fit the iPad Air 11-inch (M2).

  • !If it loses 40 percent overnight even with Low Power Mode, contact Apple Support for diagnostics
  • !If the iPad is hot while idle, stop using it
  • !If the back bulges, stop and contact Apple

How much should an iPad Pro M4 lose overnight?+

About 4 to 6 percent over eight hours of standby; owners report that as normal.
