Something wrong with your netbook configuration. In "suspend-to-RAM" mode it consumes the low portion of watt to keep DRAM content. Of course, it is possible that there are some troubled devices which don't have power saving mode or driver which can't restore it properly and system keep that devices under power but that is not right. That devices should be replaced (not bought in first place).

My notebook keeps DAYS in suspend-to-RAM mode and it is even not netbook (netbook typically has much more battery per power consumption). My friend just say me his netbook lasts at least 5 days in suspend-to-RAM mode (he didn't test more because he uses it).
