I swear by bags of WHITE rice for my cell phone and cameras.

So you take rice that's been exposed to open air and you believe that can effectively continue to absorb moisture? Like any hygroscopic material, it has has a limit how much water it can absorb. It might be somewhat effective if it's first dried out. But most people use rice that's been sitting on their shelf. Rice actually does a poor job of absorbing atmospheric moisture.

I placed white rice from a unopened bag and a hygrometer in a Mason jar. Temperature was initially 74° and a relative humidity of 58%. That's a dew point of 58.3°. Six hours later relative humidity had dropped to 47%, dew point 52.5°.

Doing the same thing with a silica gel canister reduced relative humidity from 58% to 5%. (The apparent limit of my hygrometer) That's a dew point of -1.2°.
