The April 2026 security update is rolling out in full swing, and a bunch of Galaxy devices across regions have picked it up. But it’s not going well for everyone, as some Galaxy S24 and Galaxy S25 users are reporting battery drain issues after updating to the April 2026 security patch.

April 2026 update may be hurting Galaxy S24, Galaxy S25 battery life

Users across Reddit and Samsung community forums (h/t Android Authority and Piunika Web) say that after the April 2026 security update, their phone’s battery is draining much faster than it should. Some also report that their devices are getting hotter, neither of which should happen after an update unless something’s seriously wrong.

So what might be the culprit here? According to multiple users, Knox Matrix is what’s eating up the battery far more than it usually does. It’s part of Samsung’s security infrastructure, helping detect threats, isolate compromised devices, and keep your phone secure. That also means you can’t uninstall it.

At the moment, there’s no workaround we know of. Several users have tried things like clearing the cache partition, wiping data, enabling battery saver modes, or switching to safe mode. But none of it seems to fix the battery drain on the Galaxy S24 and Galaxy S25 after updating to the April 2026 security patch.

So if you haven’t updated your device yet, it’s probably worth waiting before joining the growing list of frustrated users. Samsung hasn’t acknowledged the issue so far, but if there’s any update from the company, we’ll update this article. In the meantime, if you’ve found a workaround, let our readers know what worked for you.
