Hi Richard, I think your statement that battery life goes down "much faster" without screen curtain is relative. I highly doubt you could show that say in a two hour time period it would go down by 6% without screen curtain and only by 4% with screen curtain. You also would have to replicate exactly the same conditions, say you turn on airplane mode so nothing else may use more power during one test as opposed to the other test, then maybe play a downloaded movie of about a 2 hour length on your iPhone, first with screen curtain turned off and then with screen curtain on. I would also make sure the phone is fully charged to 100% before you start and then see what your percentage is after the 2-hour movie for both scenarios.

Well, my experience is that if I set my phone to use auto brightness under settings, accessibility, display and text size; and use the screen curtain, the brightness is always at zero unless I turn off the screen curtain. I seem to get better battery life than many, and I notice the battery life going down when my screen curtain is off for an extended time. Often because my wife wanted to see something on my phone and I forgot to turn the screen curtain back on. During those times, the battery drain is much faster than when I have the screen curtain on and using the phone the same way. Can I prove it? no. Can anyone convince me it doesn’t make a difference having the screen brightness at zero when using the screen curtain?

With LED displays, setting the screen to dark or changing it’s brightness won’t impact the battery since they’re backlit. With OLED displays it should take less energy to power a dark display, but I haven’t looked for any benchmarks on this. -- Christopher (AKA CJ) =>÷ Chaltain at Outlook, USA From: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> On Behalf Of Jenny Bomareto Sent: Tuesday, October 4, 2022 6:17 AM To: [email protected]<mailto:[email protected]> Subject: Screen brightness. Am I remembering someone on here says that it Hass to be set to dark so the battery doesn’t drain as fast and I do have it set to 0% for some reason it was on light so I had to switch it back over again too dark. And I also the phone set to lock after 30 seconds. Thanks for reading regarding this matter.
