How do I make an efficient "on-the-go" power management profile?

Hey guys,
Althogh I own a Precision 7510, I'm pretty sure that the specific model isn't that relevant to the question in the title, which is pretty general.

As far as specs go, in case you guys can estimate how much of battery time I should get:

Intel Xeon E3-1505M v5 - 2.8GHz base clock (upto 3.6~ish), 4C\8T, think of it as a 6th gen I7.
Intel P530 Integrated GPU \ Nvidia Quadro M2000M dGPU (which is like a Geforce 960)
Samsung SM951 512GB NVMe SSD (it's Samsung's OEM version, basically)
15" 1080p + Touch screen (picked 1080 over the 4k for power consumption, but I don't see the benefits as of yet)
91Whr 6-cell battery (huge battery - huge laptop)
it also has 64GB of DDR4 but that shouldn't matter, but just in case.

Most of the time my laptop is docked, and it's set to "high performance" which is fine.
But when it's not docked, and using it mainly for programming \ youtube vids \ powerpoint files, I get around 2 hours of battery life, totally absurd.

- Intel site states that my CPU has a 45W TDP and that it can be configured to work at 35W - how does that work?
- Can I disable the CPU "Turbo" (OC) option through the OS? because I need it when docked (with the dGPU enabled), but don't need it at all when I'm out, 2.8GHz is plenty fast.
- How can I make sure the dGPU never turns on while on battery?
- Will disabling the touch screen option (via device manager) do anything?
- Anyhing else that can be done and I'm unaware of?

Until now, I've been using my brother's old Macbook Air because it gave me a full (university) day's worth of battery life + it's super light.
Will it be possible to turn those 2 hours into.. 6-7hours? My battery is both huge and healthy, so besides the CPU the rest of the specs should be as power efficient as the Macbook's, so IMO I think it should be possible, but I might be wrong.
Thanks in advance guys

 

I am having the same issue with my inspiron 5000 2 in 1 too. I think its more of your battery is toast. Mine is stating it's healthy as well, but I went from 5 hrs down to 2hrs. So the reporting system is not very accurate.

 

- Check the advanced power profile settings - "balanced" or "power saving" or such. There's a whole bunch of them, and there's a special "on battery" set vs "plugged in".

- Pay attention to your background processes, they might be spending watts for unnecessary tasks. Try googling up a good guide for getting rid of unnecessary programs/processes/services. You can measure idle consumption with a W-meter while plugged in. 64GB RAM probably matters.

- The battery indeed tends to lose a large part of its capacity over a few years. The lifetime is around 500 full cycles. Gets worn even if plugged in all the time, especially if at 100% - 50% is much healthier, 80% is a reasonable compromise if using as UPS.

 

What you need to do is get ThrottleStop, learn it, and dial it in for your machine's hardware. Additionally, since you are running SSD storage, you should look into enabling HIPM+DIPM in Windows Power Settings if it isn't already. Setting up Throttle Stop will give you insight as to what C state your machine is going up to. Higher the C state the better for battery life. My machine gets ~50% C7 "Package C State" when idling / running Chrome and doing minimal tasks.

You can see how I have my Throttle Stop setup here:

Additionally, here is the link to check out for tweaking your registry to allow you to set your AHCI link state to help reduce your SSD's power consumption:

FWIW, I get ~4 hours of usable time on my Dell 7577 w/ i7 7700HQ and a 55WHr battery when just browsing using Chrome and doing other light tasks, but I also have my system processes and services trimmed very nicely. Don't forget to clean up your Task Scheduler as well.

Also as far as browsers go, Chrome is a battery hog. I hear Edge can save you some juice if you're into that sort of compromise.
