Yeah, if applications send lots of data, naturally that will increase
power consumption dramatically. For these cases it would helpful if
you could install tcpdump to the device and take a dump of traffic.
You could do it like this:

tcpdump -i wlan -w dhcp-1.cap

And then attach dhcp-1.cap to the bug report. That would help a lot.
