Five minutes into a fresh session, with the reset timer showing 4 hours 55 minutes remaining, 28% of my session allowance had already been consumed. Claude Code sessions had been cleared for the previous 24 hours, Cowork was disabled, Claude in Chrome was off, and I was on a single browser and device. Over the following four idle minutes, with no prompt sent, the figure rose to 32%. This pattern has held for the past 24 hours, with the session allowance reaching 100% within roughly an hour on several occasions without matching use on my side. I have been on the platform daily for more than four months and have not encountered this before. Anthropic published a postmortem in April 2026 concerning a caching fault that produced a similar pattern, so this seems worth reporting rather than absorbing. If you would like to check your own account: open Settings → Usage at the start of a session, note both the percentage and the reset timer, remain idle for five minutes, then check again. I would welcome your figures in the comments.
