Explanation
The key clues are: no new apps installed, the update was removed, and the poor standby time persists. Because the symptom survives a software rollback, the root cause is hardware-related, not software. Overheating is the most likely culprit-a device running abnormally hot draws more power even in standby, as the processor throttles, thermal management circuits activate, and battery efficiency degrades. Zero-day malware and OS corruption are software-layer issues that removal of the update would likely address. Time sync failure does not meaningfully impact battery drain.
