Hi all!
So I want to extend the battery life and I thought of reducing the power draw from my OLED.
I’ve already reduced the power by a few mA by turning the contrast to 50%.
What else can I do?
Can I turn down the refresh rate on the OLED? I only need to update a few numbers once a second.
The library I’m using is MultiLCD but the commands apply to any library
The communication is over I2C and teh OLED has to be on all the time.
Every µA counts
Thanks for any help!

You can put the display in deep sleep, and the current consumption falls to less than a 1uA, assuming your using the 3.3V version without the regulator on the back.

Yes I’m using the 3.3V version without a regulator, at least that’s what I think. IM feeding it 3.3V since it’s the system voltage.
Wouldn’t this clear everything on the display and result in flickering?

Sure, it will turn the display off.
An LCD display or ePaper display would be a far better to use for low power use, if you want a display that is low power and remains visible.

Thanks for the tip, I’m looking into it! IM having a hard time finding a LCD or an E-Paper graphic display that’s around the same size as the OLED (1.3")
Could you link to a place where I can find these? I’ve looked at DigiKey and Farnell but the selection is very small

1.56" ePaper displays are easy to find on eBay.
