Default 2009 RX350 draining battery

I just got the battery changed last October. Now coronavirus situation, if I let the car sit more than 2 weeks, I can't start the car easily and can hear unsmooth sound from starter. Today I tested static current of my car. It's about 90MA and almost three times of 30MA as other cars. I unplugged the radio fust No.1. It decreased to 20MA. I checked the radio fuse current. It's almost 70MA. Could somebody test yours to compare the value? It's located at the fuse box Radio No. 1. To test, you need lock the car with remote control for a while and unplug the fuse. Use MA to test(If the multi-meter pin is to big to reach inside, you can point to the metal nearby. Please see my picture ). Mine is 70MA. That's too much.
