Hi Guys,
I was sick and tired of 3.5 hours battery life with the 960 EVO 1TB. I bought the new Intel 660p QLC SSD 512GB (for now, waiting for 1TB to be release) for $100. It's running so much better! I'm getting 7+ hours again! I haven't tested too much but I would say if I were to surf and do light task I should get somewhere around 6 to be honest. I just got it so further testing to be done.
Here are some brief specs:
MBP 15" mid-2014 (PCIe 2.0)
Speed: 900 write/1500 read
Power consumption: 0.17A idle/0.80A active
TRIM: On
Brand new High Sierra install, the system idles at 11-12w draw. This is according to istatmenu. My battery has like 30-40 cycles on it. It's new.
Let me know if you guys have any questions!

I wanted to post this to make sure that I'm fair to Samsung in my review. I recently found out that the reason I was getting 3.5 hours on the Samsung was because I had two apps that was preventing my laptop from switching to integrated graphics. It was solely using Nvidia gfx which is a huge power draw. The apps responsible was Menubus and Screenconnect. For some reason these two apps kept the Nvidia graphics card on 24/7 while on battery.
Without these two apps preventing the laptop from switching to Iris Pro gfx, I'm now getting more like 5-6 hours of battery life on light use. This still not as good as the Intel 660p but it's not stupid bad like 3.5 hours. The laptop is much cooler while running on the Iris Pro as well.
I would say with the Samsung you're losing somewhere around 30-60 mins of battery time. Which is not bad if you're on a mid-2015 MBP 15" since you're able to take advantage of the speed performance. For those of us on PCIe 2.0 x4 it's not worth the extra juice drain for the performance. The Intel drive will almost max us out.
The 960 EVO idles at around 0.40A average (you could see from the picture below it spikes up and down between 0.36A and 0.53A while it's idling and spikes up to 1.0A-1.4A during full use (running Blackmagic disk test).
Before my entire laptop was idling at 23-24w average, after shutting down those two apps to allow Iris Pro gfx to switch, it's now idling at around 14-15w average. I pretty much gain 3 hours of battery life from this simple fix alone.
I'm quite happy with the Intel 660p so far and I'm probably gonna end up returning the 960 EVO.
BIG FYI - I'm also running Volta to undervolt the CPU by 80mV. This probably gain about 20-30 mins of battery.
I hope this helps someone out there. Cheers.
