I would like to know how long can Raspberry pi be on without turning it off? I am looking for the maximum uptime. It's been 2.5 years since the Raspberry Pi was first launched and I am curious to know what the maximum up time anyone has achieved.

Is it possible to have it run a full year? So 24h a day, 7 days a week and 365 (or 366 :) days a year??

  • In my case, so far 4 months 24*7, only 3 reboots.

  • 71 days so far, since the last power outage. (So not that much to win a price...)

  • At times for me, continuous A/C power can be a roadblock to long uptime. I've recently discovered that the unit can be powered from the 5V GPIO pin. I have an Adafruit USB to TTL serial cable connected to my Pi for debugging and I found that I couldn't turn the Pi off until I disconnected the USB cable from the laptop I was using to monitor the serial console port. My other big challenge is that I only have 256 MB or RAM and run out of RAM periodically. I've added background services over time that use up all the RAM at times. Sep 30 '14 at 22:25
  • $ uptime 11:20:54 up 316 days

I had a quick scan of http://www.raspberrypi.org/forums/viewtopic.php?f=62&t=49488&hilit=longest+uptime

563 days was the longest I noticed in the post.

The longest I've done is 35 days during a test. I normally switch off overnight.

  • What happened after 563 days? did you just turn it off or did it die?

  • Oh, sorry, just realised you only did 35 and not the 563 - my bad :)

    For all I know that one will be over 700 days now!

Yes it is certainly possible, as it happens I had to rewire a socket yesterday so I currently have an uptime of 1 day but it was getting on for 6 months prior to this. even then it was unplugged as I was reorganising my desk.

I'm not over-clocking it however, not sure if this would make any difference.
