Using too much battery on iPhone 14 when running in the background #2046

Yesterday night, I executed the command below to run iSH in the background:

cat /dev/location > /dev/null 2> /dev/null &

Then I slept.

I'm using iPhone 14. I remembered, the battery of my iPhone is $64$% yesterday night. But when I woke up, there is only $20$% battery.

I also have an iPad (7th generation), and I also ran iSH on it in the background. But it only used $8$% battery through the whole night.

Why does iSH use so much battery on iPhone 14? How to set a memory limit?

These numbers don’t seem unusual to me. We can probably look into your battery usage in more detail if you want but I don’t see anything wrong here at first glance.

Just the nature of emulation I guess.

The daily power consumption in the background will scare you, 50% before going to bed and 10% when you get up. Check the background are ish.

iPhone 13 Pro . Even when I manually turn off the background, it's still draining in the background. I don't understand why.

Are you doing it through the Settings app? That's not going to do it.

Since that you've specifically executed a command that enabled running iSH in background, there's also this command that can suspend iSH app again when leaving into background, especially if you want to conserve iphone battery after using a command that started using background.

killall -9 cat

It's on you if you've left iSH running in background and forget about it.
