David Hanak If you have an iPhone (or iPad), you've probably noticed that when you repeatedly wake up, your device wakes you up after 9 minutes, not after 10. The time of the so-called Snoozing mode is set to nine minutes by default, and you as the user can't do anything about it do. There is no setting anywhere that would shorten or lengthen the value of this time. Many users over the years have asked why this is. Why exactly nine minutes. The answer is quite surprising.
I personally ran into this issue while trying to figure out how to set a 10 minute snooze. I believe that more than one user has tried something similar. After a short look on the Internet, it became clear to me that I can say goodbye to the ten-minute interval, as it cannot be changed. In addition, however, I learned, if the information written on the website is to be believed, why this feature is set to exactly nine minutes. The reason is very prosaic.
According to one source, Apple is paying homage to the original watches and clocks from the first half of the 1th century with this setup. They had a mechanical movement, which was not brilliantly accurate (let's not take the expensive models). Due to their inaccuracy, the manufacturers decided to equip the alarm clock with a nine-minute repeater, as their stands were not accurate enough to reliably count down the minutes to ten. So everything was set to nine and with any delay everything was still within tolerance.
However, this reason quickly lost its relevance, as watchmaking developed at a dizzying pace and within a few decades the first chronographs appeared, which had a very precise operation. Even so, the nine-minute interval allegedly remained. The same thing happened with the transition to the digital era, where manufacturers honored this "tradition". Well, Apple behaved similarly.
So the next time your iPhone or iPad wakes you up, and you press the alarm, remember that you have nine extra minutes of time. For those nine minutes, thank the pioneers in the field of watchmaking and all the successors who decided to follow this interesting "tradition".

If the old alarm clock was delayed by a minute in 9 minutes, it took almost an hour from evening to morning. I mean, then it didn't really matter if he went to postpone it by 9 or 10 minutes, didn't it? :-)
Well, that would theoretically be the case if the snooze wheel ran all day. However, if it always started with an alarm and its rotation would be 9 minutes +- a few seconds, a reset could theoretically occur after each press. Unfortunately, I do not know the details of historical automatic movements, so I will have to trust the information provided :)
Steve wanted it that way! :)
So I read that it was a little different with those minutes:
"Due to the structure of the machine, a time of about ten minutes is then necessary until the hour hand connects again with the mechanism for putting it down. According to previous knowledge, however, they assumed that 10 minutes is long enough for a person to fall into a deep sleep again, so they shortened it a bit. That's how today's 9 minutes came about. Over time, this time became the standard in other watches as well, and eventually ended up in the iPhone itself.”

I don't really like the deep sleep interval explanation here. I'm not sure if it's possible to reach the deep sleep stage in 10 minutes and if so, does anything change when the timer is at 9 minutes…
It would partially make sense. But it doesn't make much sense that in 10 minutes a person will fall into a deep sleep and not in 9 minutes.
But that's stupid... I personally don't use an alarm clock from Apple, but customization is perhaps normal these days... but let's wait for the next 2 versions of iOS and it will be announced with great pomp that the alarm clock will support it...
It is more about the fact that if the alarm clock rings, for example, at 6.00:10, you often press it only after 60-6 seconds (ie, for example, at 00:30:6), after snooze, the next ring will ring, for example, at 09:30:6. Therefore, even with a minute delay, you are able to get up at 10:XNUMX
Unfortunately, I can reliably fall asleep again within those ten minutes, I would need two or three.
I like iPhones, but this is a total piece of shit and it can really piss me off. For example, if you have an alarm at: 9, 9:10,9, 20,9:30, 9:9... it rings like this: at 09,9, 10,9:18,9, 20,9:27,9, 30:XNUMX, XNUMX:XNUMX, XNUMX:XNUMX, XNUMX:XNUMX... etc…. I've never seen anything worse on a mobile phone.
