Apple Adds 3 iOS 26 Lock Screen Tweaks, Expanding iPhone Customization

Q: Are the new 3D spatial wallpapers in iOS 26 secretly draining your battery to create that depth effect?

Probably not in any major way. Apple’s new Spatial Scene wallpapers in iOS 26 do use motion-based rendering to create a 3D depth effect when you tilt the iPhone, so they are not completely “free” in power terms. But based on what Apple has described, this is a subtle lock screen visual effect, not a continuous heavy animation like a video wallpaper or graphics-intensive app. The feature works by adding depth to personal photos and responding to device movement, which likely means the iPhone uses motion sensors and some extra graphics processing on the lock screen. That can increase battery use slightly, especially if you wake the screen often or spend a lot of time on the lock screen. Still, there is no evidence in the material provided that Apple’s Spatial Scene feature is “secretly” causing serious battery drain. The bigger battery impact in daily use is still more likely to come from display brightness, always-on display behavior on supported models, background app activity, cellular signal strength, and other system features. In other words, Spatial Scene may add a small overhead, but it is unlikely to be a main battery culprit for most users. If battery life becomes a concern, the practical fix is simple: switch back to a standard photo wallpaper and compare. Since Apple lets users customize wallpapers easily through Settings > Wallpaper > Customize, it is easy to test whether disabling the 3D effect improves endurance on your device.

iOS 26 lets iPhone users resize the lock screen clock, move the widget dock and add a 3D “spatial scene” effect to photo wallpapers.
The clock can expand to roughly one-third of the screen, but only one font currently supports the larger size and changing size disables font switching.
Widget placement is still constrained: users can drag the dock near the bottom, and expanding the clock automatically pushes the dock there.
Spatial scenes work only with photos—not Apple’s built-in wallpaper collections—while lock screen controls also gain automatic color accents in iOS 26.
The update builds on iOS 18’s lock screen control changes, with iOS 27 betas already testing another option: shrinking the clock.
