Is there any downsides to auto rebooting every 10 minutes?

Kurt

At the moment its set to 18 hours auto reboot. Is there any negatives of having it set much shorter to 10 or 30 minutes? Does it wear out the phone if it reboots all the time or is it fine?

If I understand correctly, auto reboot puts the phone into "BFU" state? And that is much better for security as the phone is much harder to break into in BFU rather than AFU? is that correct?

Yes.
Depending in which app you use, you could loose some data if you haven't saved your work before the reboot.

The only thing I can think of is the impact on battery life. I used to have my auto-reboot set to 4h and couldn't help but notice that every time my phone rebooted, it drew a lot of power from the battery for a minute or two.

Kurt

SuperNoodle ah yes, battery life would probably go down quite a bit as I use my phone a lot so it would have a big impact

You won't receive phone calls since the PIN code won't be entered.

Eirikr70 is that the same with all notifications too or just phone calls?

I wouldn't want to miss an appointment call or emergency call from friend or family :/

Kurt The topic of reboot has been discussed a lot on here. I'd read up on the prior discussions which includes these:

You can unlock permanently your SIM :
Settings > Security > More security settings > SIM lock > toggle the Lock SIM option
This will probably also allow someone to use your SIM in another phone without PIN.

ErnestThornhill thank you those threads are informative. It would be cool if graphene had a "snatch" feature that would auto reboot the phone if it detects sudden movements from the phones sensors (gyroscope or whatever). So if someone grabs your phone it may help protect it

Kurt If that's what you're after, you may want to look into Cerberus App -> AutoTask Rule Configuration -> Event (Device Moving or GeoFence) -> Action (Lock). It's a third party app that requires a lot of permissions and it's quite invasive and problematic, but it does the job.

Not the answer to your question about the disadvantages of short auto reboot intervals, but maybe it will help you anyway:

Maybe a multi-stage model could be something for you: A slightly laxer auto reboot timer for everyday use (however short that time may seem acceptable to you) to avoid the disadvantages already mentioned here and if you get into situations where there is a higher probability that you might need the increased protection of the BFU state, shorten the auto reboot timer manually in the settings.
