Samsung's security patch released in early April is apparently causing users more problems than just with Microsoft apps. In forums, owners of the Galaxy S24 and S25 series are primarily complaining about devices overheating and significantly reduced battery life. Some users believe they have found the cause.
Battery Drainer
“I charged it fully 35 minutes ago, its at 65% now. I've turned off everything. Turned on battery saver. Restarted. Ran a virus scan. Ran diagnostics. Nothing seems to cool it off,” writes a frustrated user of a Galaxy S24 in the Samsung community forum. Numerous users confirm his experience (via Android Authority).
S25 users report the same in both the Samsung community and on Reddit: “My battery has been trash for a whole 2-3 weeks as a s25 ultra user,” complains a Redditor in a thread on the Android subreddit. An owner of a Galaxy S24 states that his battery lasts less than three hours and takes five hours to charge to 100%. However, an owner of a Galaxy S25 reports that his phone is dead after just two hours.
A moderator of the Samsung community advises users to charge the device in Safe Mode. However, according to numerous user reports, this does not change anything.

Knox Matrix possible culprit
Some users seem to have identified the culprit and are sharing screenshots of their devices' battery consumption. The Samsung security feature for the connected device ecosystem Knox Matrix stands out clearly. Several screenshots show that Knox Matrix consumes an unusually high proportion of the battery power. The app appears to be constantly running in the background and overloading the CPU.
There seems to be no interim solution. The app can be closed and the device reset to factory settings. According to one user, they have done both and still have the same problem.
Samsung does not seem to have confirmed the error yet, and it does not occur for all users; a Galaxy S24 from our editorial office runs completely unobtrusively after installing the security patches from early April. However, Samsung will likely have no choice but to release another update as soon as possible to fix the known problems.
