if you compare dram-less nvme, their power consumption are about the same.
case in point, 980 is maxed out at 4.3W (and about twice as fast both on read and write)
SN550 is maxed out at 3.9W (and about 50% faster on read)
so if you REALLY value about battery life, you should care about performance per unit watt. 980 consumes 30% more power but performs 100% better, so for a given task, it is actually uses 40% less power, all for 10 dollar more.
honestly, given the 980's price tag and performance, i don't know why anyone would go for anything else for general home use(esp at MSRP)

any reason not to jump on this deal
what stands out is the
Warranty: Limited 5-year or 800TBW more then double most
and it VERY LOW POWER 3.3v - 1a
many others are 3.3v - 2.8a those will get very hot and suck batteries dry

i looked at the Specs
980 FOR THE 500gb
Power Draw:
4.3 W (Active) 5.9 W (Max) 5.0 mW (Standby) [B]~1.8amps
Endurance TBW: 300 TB
the Gigabyte 512gb
Power Draw:
Avg. Read : 3.3W ; Write : 2.8W (Idle) 1.8mw ~1amp
Warranty: Limited 5-year or 800TBW
so the Gigabyte is $14 less
the Gigabyte is slower but still faster then any Sata SSD
uses ~1/2 the power and is Guaranteed to last more the 2 times longer

BUT this is a gem for in a laptop with 1/2 the drain and very cool
in a desktop it would not typically matter EXCEPT LASTING 2x longer

No. Your storage device in normal usage won't go full power for more than 30secs. It's both very unlikely for your laptop to do something that requires full power, and it's unlikely any super high load task would last for longer. The max power rating on SSD is most likely thinned out to less than 10%. That makes the difference in number much smaller.
This is not yet considering that your CPU is going to be fully tolled when your SSD is doing heavy work. That is easily more than 15W, and some times all the way to 65W. So even if your SSD on full power uses 10W, compared to something uses 0W (magical SSD!) you are getting 66.7% longer battery life by the most optimal condition. Real world number will be somewhere around 5% mostly.
The more important factor for battery life would be sleep state power consumption, but it is not on the spec sheet that I can find.
It is recommended to read benchmarks like what Tom's Hardware is doing, which includes efficiency tests. Do not rely on spec number as they are defining only the envelope and sometimes just lies.
