How do you drain the iPhone battery for testing?

[nategold]

On the Mac in terminal you can type yes > /dev/null in multiple terminal windows to drain the battery for testing. How do you do this on the iPhone? I have the LibTerm terminal app but it says yes: command not found. Any other way?

Drain battery? Perhaps you could it use until it dies and then leave it to "die further" without turning it on/charging?

I meant a fast way to drain the battery.

There's no reason to do this. You want to check your battery health you can just look it up in the settings. Or if you think a program is draining your battery just turn off your iphone and turn it on again. 'testing' is just something for people who don't know what the **** they're doing.

There certainly is a reason - to test a new charger.

Test what? A charger has a set wattage you can see on the charger itself and the iPhone has a max wattage it accepts. So get a 20W or above charger and it will charge at 20 watts. There's no charger that's gonna work slower or faster if it's at 20w or above.

How to test your charger:

1) Wait until your iPhone battery isn't full.
2) Connect it to the charger and wait awhile.
3) Check the battery level.

If the battery level went up, your charger works. (I have no idea why you think you need to test this)

Are you trying to see the wattage of the charger as it is charging? With Coconut Battery app you can see the current wattage of the charger while it is charging.

Have a look at Ampere - battery charge info by CrioSoft LLC (be careful there are several apps with very similar names).
