Surely you must have rebooted it since then? It's possible it could last through a reboot I guess, since it's only displaying the difference between current_time and start_time, not actually counting every millisecond when it's in the background.
Edit: ok, yeah, I just tried it: reboots don't reset the stopwatch, whaddya know!
It just has to record the start time, then show the duration between the current clock time and the saved start time. As long as the clock can still sync or be manually set after being charged, there's no reason it shouldn't work.
yes but i think the stopwatch on mine just reset after booting with 1970 date. its been quite a while since i used it so my memory could be corrupt tho
Could be. I have no idea how it's implemented in this specific device/app. It might immediately resume tracking the duration when it boots (or you opened the app before correcting the time) and cancels the stopwatch when it finds the start time is seemingly in the future. If I still had my iPod Touch, I'd try to find out — decent nerd sniping opportunity.
Just compares the time started vs the time now. So if you set your device clock back 10 years, start a timer, and set the time back, you'll see 10 years has elapsed.
Timers might use just a wee bit more because they will have a check to produce an alarm when the timer expires. But we're still taking negligible values.
Not even, really. They use "wake timers" the same way every other app does, the loop in the OS runs for that regardless of if an alarm exists. It's just one more item in the queue that gets ignored until it goes off. And stopwatches don't even have that.
There was some person who started a stopwatch on their iphone and they were unhappy that there wasn't a way to keep it going when they replaced their phone.
It wasn’t me, but I will be sad when I can’t keep the same stopwatch running. It’s weirdly comforting whenever I lose track of what year it is since COVID or disassociate to see a token of time passing

That's good to know, I would have thought it wouldn't.

I started a stopwatch on my ipod touch back in 2011 and it was still going last time I found and charged it up around 2017.

Fun fact: The timer app doesn't even need to run in the background. When you started it, it recorded the start time. Now it's showing you now - then.
You could turn off your phone for 10 years, let the battery die, come back, reset the clock, and the timer will still be running!
JelleWho@lemmy.world · 4 pts · 22d
You can set your time backwards, then start it, and then update the time again

Only 14 more to go…
11111one11111@lemmy.world · 0 pts · 16d
14 more? Whatre you running 1/3 or 1/5 mile long tracks lol you picked the only number that wouldnt work with the standard 1/4 mile tracks🤣
violentfart@lemmy.world · 1 pts · 16d
I used 14 since 30 years (15x2) is a normal minimum duration of employment.
Boe@lemmy.blahaj.zone · 32 pts · 22d
Seems more like a startwatch

Stopwatch: “I’m tired, boss.”

Here's mine !! (Not accidental)
Zorque@lemmy.world · 16 pts · 22d
Are the laps when you last checked it?
nope@jlai.lu · 2 pts · 21d
They are not ! It's mostly when I felt like it, although I did try to get 10000 and forgot thus the 10003 lol
Sev5000@lemmy.world · 18 pts · 22d
hah, made me check if the stop watch app I installed when apps were the new hot thing is actually still going..
ianhclark510@lemmy.blahaj.zone · 12 pts · 22d
Watch out man, my bf swears that leaving a timer going in the background will kill your battery
