Husband was charging his phone under mattress ..?

My husband was running a quick errand this morning when I was still in bed and he kissed me goodbye and said his phones here bc it was dead. I said no problem and didn’t think about it, but later his alarm was going off and I was trying to find it but I couldn’t !!

Then I realized he had put the phone UNDER our mattress, as if he didn’t want me to see where it was ..?

Is this suspicious??

I’m so confused
