Low Power Mode vs. Normal Power Mode Battery Test

Big thanks to Autonomous for sponsoring this video.

Apple says Low Power Mode helps the iPhone last longer. But how much longer? After 80 hours of active testing, that's we aim to find out in this video.

TEST NOTES:
- Screens were calibrated to 200 nits with auto-brightness turned off, except for in the second test where auto-brightness was turned on.
- Speakers calibrated to the same decibel count.
- Tested within equal distance of a mini cell tower.
- Tested in a temperature controlled environment.
- It's the same iPhone in all tests, with a battery health of 100%.

Low Power Mode vs. Normal Power Mode Battery Test

How is low power mode?
Gattuso: "Sometimes maybe good, sometimes maybe shit"

Low power is more beneficial for when the phone is in your pocket, it stops background refresh for apps, downloads, email fetching, and dims the screen faster after receiving a notification or something that lights up the screen, so of course having the phone on most of the time doesn’t work at all.

In other words, it’s background tasks that get benefits from low power mode.

I would like to see this test in some androids too. I think iOS is normaly super efficient

[Francisco]

I would like a speedtest between low power mode and normal

[sadieangelina]

Does low power actually increase battery life?

Well no, but actually yes

[rafaqilaharis]

Please do a True Tone on vs True Tone off battery life test

[SpaceWithSam]

His videos are too fascinating and entertaining to watch, also informative at the same time, excellent work!

The Low power mode restricts background processes and lowers the refresh rate when fast scrolling. In your case, there are very few fast scrolling session, and there are virtually no demanding background apps like messaging apps, multiple mail accounts and other realtime notification enabled apps, that's why the difference between two modes is negligible.

I use a 6S Plus and it saves much more power but that's again probably cause of the older phone.

[blakeweitzman]

I think it’s much more affective with older phones where the processor might be working harder for more normal tasks so that CPU cap will make a big difference, on top of that the older CPU’s are less efficient and usually paired with smaller batteries

[supercool]

I think we will see a significant difference while comparing the Samsung/Android devices.

[matin.]

It’s about years that I’m trying to find video like this
Thanks 🙏🏻🙌

As someone who’s used an iPhone 5s and is currently using an iPhone XR, low power mode is HUGE for the older devices. Since their processors aren’t as powerful, my old iPhone 5s could get an extra 30-90 mins with low power mode enabled from 100%, where as there is no major difference from day to day simple tasks on the XR. However, intense gaming or video editing has helped me squeeze an hour or so more with the iPhone XR on low power mode

To people who are curious about the performance with and without low power mode:

Geekbench 5 CPU without Low power mode:
Single Core: 1332
Multi Core: 3282
Geekbench 5 CPU with Low power mode:
Single Core: 786
Multi Core: 1487



3D Mark Slingshot Extreme without Low power mode: 5190 pts.
3D Mark Slingshot Extreme with Low power mode: 4298 pts.

EDIT 1:

Geekbench:

Runtime: 03:35
Battery before test with low power mode: 71%
Battery after test with low power mode: 70%

Runtime: 02:06
Battery before test without low power mode: 70%
Battery after test without low power mode: 68%

I’ve been asking for this vid for about a year lol finally happy to see it

[croissant]

As someone who always uses low power mode everytime. I feel like i needed to watch this

[TheMoose]

6:50 That’s… not how margin of error works… like at all. You don’t just add percentage points to the one you think should’ve won because “margin of error”.

[jesselam]

I think you can conclude that low power mode makes the most difference when doing more intensive tasks, for day to day tasks that aren’t intensive to begin with it doesn’t make that much of a difference

[gd.ritter]

I would expect normal mode power draw to vary greatly by what background tasks/apps you often use. If you have many things chugging in the background or while in standby, the difference should grow

[ast]

Yaaay it lasts 15 minutes longer.
Perfectly useless.

But yeah if I enable it at 20%, I save 2 minutes. Well that's worth it, right?
