Why Is My Battery Draining Overnight. My iPad Air battery life suddenly got so short. I have an array of fancy expensive test equipment.
What it does is continues to discharge the battery even after shutting the engine off. Some older or cheaper converter chargers arent equipped with a shut-off that stops overcharging. And this is not the first time its happening I am facing this problem after I upgraded to Windows 10.
However the best way to troubleshoot battery drain issues on these trucks is to solder up a test light with some test clips.
This is how much battery your iPhone 12 has left. Your car battery is still powering some components once the engine is turned off such as the clock and anti-theft features. The light will come on if there is a drain somewhere. If you processor is not power efficient then it may lead to battery drain fast.
