iOS 26

Is it a good idea to upgrade my iPhone SE2 to iOS 26? Is it a good idea to postpone the upgrade after Apple finding more bugs? Will the battery be used up faster when I upgrade my iPhone SE2 to iOS26?

Upgrading can be fine, but you should be prepared: expect a short-term battery and heat hit right after installing, some early users report bugs on day‑one builds, and many experts recommend waiting for the 26.0.1/26.1 patch if your iPhone is critical for work or travel.

Immediately after a major iOS update your iPhone will do background work (indexing, model downloads, app updates) that commonly causes higher battery drain and warmer operation for 24–72 hours; Apple says this is normal and usually temporary.

When Apple says your iPhone is “indexing,” it’s essentially re‑organizing and cataloging your data in the background so the system can find things quickly later. Think of it like a librarian going through every book in a library, tagging and shelving them so you can instantly find what you need

Over the longer term, new features that demand more resources can produce a measurable, ongoing battery impact for some users, depending on how heavily you use those features.
