Intel Corporation Wireless 7260 (rev bb), iwlwifi, powertop usage

I have this card in my Dell XPS 13 (4303): Intel Corporation Wireless 7260 (rev bb).

When surfing the web, powertop shows the power consumption of:

    5.66 W      2.4 pkts/s                Device         Network interface: wlp2s0 (iwlwifi)

but sometimes gets up to 9W.

In Devices tab it shows:

    100.0%        Radio device: iwlwifi

Is this normal? I have poked around with power_save, power_level kernel params (no effect). It does seem like this wifi card in on 100% of the time no matter if I transfer anything or not.

Any tips on improving the situation? Including getting a less power hungry replacement...
