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. – Roberto Sep 29 '14 at 11:36
  • 71 days so far, since the last power outage. (So not that much to win a price...) – Ghanima Sep 30 '14 at 8:48
  • 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. – HeatfanJohn Sep 30 '14 at 22:25
  • $ uptime 11:20:54 up 316 days – lenik Oct 1 '14 at 2:22

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? – SaturnsEye Sep 29 '14 at 13:11
  • Oh, sorry, just realised you only did 35 and not the 563 - my bad :) – SaturnsEye Sep 29 '14 at 13:20

    For all I know that one will be over 700 days now! – joan Sep 29 '14 at 13:46

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.
