I’ve searched this forum and there are no clear guides on how to reduce the power consumption of the MangOH Red. Is there a guide for disabling hardware, either via the hardware switches or via GPIOs? Currently power consumption averaging is around 160mA (@ 5V), with gnss and radio turned off. Is there a way to disable wifi and bluetooth, or other devices? I am measuring power over the USB when connected to CF3 USB. ---

I don’t remember the specifics, but I think there is something you can do to save some power by disabling the battery charging capabilities of the system. Do you need battery charging? Also, please read through the [Legato Power documentation](https://docs.legato.io/latest/legatoServicesPowerMain.html) to get some ideas of how you might be able to change you software to more effectively save power. If you have the `devMode` app installed, you will need to remove that to allow the device to enter lower power states. ---

Thanks. I have tried those and it’s all marginal power savings. Shutting down all services saves the most power, I need to spend some time and document everything. ---

What features do you want to use on the platform? ---

Hi Asyal, I’m mainly wanting to use GPS, the modem (WP8548) for networking and SMS, also an IOT card which allows serial communications. All other peripherals are not necessary. Cheers, Simon ---

Are you ok to make hardware mods to the board? Like removing resistors etc.? ---

Yes, I can do that. What resistors can be removed? And what power improvement could I expect? ---

Quite a bit actually. What numbers are you wanting to have and in what modes? I’ll need to dig through some of our test numbers and send that to you tomorrow. ---

Can you try the following: \*Mediatek at reset (AT!WIOCFG=25,4,1) Measure current: 50-75mA Measure current USB SS mode: 30mA ---

Thanks @asyal, this saved around 30mA. However the command should be `AT+WIOCFG=25,4,1` ---

Thanks for that. …here are the numbers we get Radio is ON: 150-$400mA • Radio OFF (cm radio off): 140-180mA • Mediatek at reset (AT+WIOCFG=25,4,1) o 50-75mA o USB SS mode: 30mA ---

I have similar a problem. A mangOH Red board with WP7702 modem. I cannot get below 36mA in suspend. Is there some other things that can be done to get down to below 5mA? ---

Still not possible to get below 37mA. Any ideas? ![image](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/b/bda27220ae84c152c4828404c3bd00515a3c1f20.png) ---

is it in ULPM mode? ( i can see there are spikes so I suspect if this is in ULPM mode) how did you measure the module current? In whole mangoh red board? or the current going into module? [Next page](https://mangoh.discourse.group/t/reduce-power-consumption-for-mangoh-red/2909.md?page=2)
