'Auto Brightness' setting - Uses more power?

[Kraftwerk]

Just wondering if the 'auto brightness' setting uses a lot more power on the Moto G?

I've heard that it can on certain phones, but I now have version 4.4.4 and wonder if it uses any more power than if leaving the brightness setting at half way?

Thanks

Initially mine was set to low like 25-30%, but now I use auto. It doesn't seem to affect battery life in my case even though I've read disabling auto improves battery life.

I suppose it depends on how you use your phone. I would try auto and see how it goes.

I think it's less about which mode you use (auto or manual brightness) and more about the actual brightness level. Auto brightness in a dark environment (where the display would be automatically dimmed) would be more power efficient than auto brightness in broad daylight (where the display would be automatically brightened).

So manually setting a lower brightness value than auto brightness would use should improve your battery life. The downside is that you may not be able to see your display if you suddenly walk outside, for instance. On the other hand, if you manually specify a higher brightness setting than auto brightness would, you'll probably decrease your battery life.

Like so many things, it ends up being a trade-off or compromise between convenience (not having to manually adjust your brightness) and battery life.

Protip time: You can use an application like Lux to change how your auto brightness adjusts to different environments. Configured cleverly, you can use this to get the best of both worlds - brightness that adapts as needed while still getting good battery life. :thumbup:

Thanks for replies.
I will give 'auto brightness' a go and see how I get on.
