Battery draining ridiculously fast

No clue what is causing this. Maybe someone here might know. The battery on my RB2015 is draining RIDICULOUSLY fast. I am talking <2 hours of general web browsing. The unit always stays warm even though the CPU is never above 10%. I check Intel XTU and it is operating fine. I even went as far as to limit the maximum CPU to 20% when on battery and it still drains crazy fast. Any ideas?

 

Maybe it's software related if this starts to happen recently?
Also check you battery wear level, maybe it's time to reset the battery?

 

It's possible it's software related but the battery should stay up longer with me gimping the CPU. I've drained the battery completely and re-charged it a few times so it isn't that. Like I said the laptop is warm like it is doing something but it's just idling most of the time.

 

BatteryInfoView will show the battery status and the power drain while the Sensors tab of HWiNFO provides useful info about the hardware status including the CPU power drain. ThrottleStop 6 (click on the C1 button) should be able to show the CPU power states - you should see the system spending part of the time in the lower power states.

Thanks I'll check it out.

 

It's possible something is using the dGPU instead of the iGPU. That would definitely accelerate battery drain.

 

You know I was up late last night and I was thinking that then I thought hey this is Optimus you can't do that, then I remembered you can default EVERYTHING to use dGPU!

 

So it's definitely set to Auto and I went through the list. The only thing running that's configured to use the dGPU was GeForce Experience. I would assume everyone has this installed though?

 

What C1 button?

 

In the older Throttlestop 6 there is a C1 button in roughly the same place as in the C7s on ThrottleStop 7 that you see here (I think that will have the same function). A CPU that is not fully loaded should be spending a significant amount of time in the lower power C states.

Try installing the stock gpu drivers from the Razer website including the integrated intel gpu driver, I also had this problem on an earlier Blade and this fixed the issue.

 

Going stock unfortunately is no solution since you won't be able to do the proper scaling fix with the newer Intel GPU drivers and you won't be able to play any newer games such as GTA V. Pre-today's driver update GTAV runs like ass. Post, runs like a charm for everyone.

 

Started up 8 minutes ago. Was at 92% now at 85%. Here's an image from my ThrottleStop

40 minutes now and 69% remaining

 

Either something is causing CPU/GPU drain or you just have a bad battery.

I'd recomend a full restore using the built in recovery. Then see how battery is. If its still bad return it for another.

Also what brightness are you running the LCD at?

For comparison in about 45min on lowest LCD brightness while streaming from TWITCH I just used 11% so I should get about 5-5.5hrs. I also have latest Intel and nVidia drivers.

 

Middle to high. Looks like I was able to crank out about 3 hours today.

 

Any insight on the C states I posted?

 

I wouldn't be amazed if the brightness has a good bit to do with it. I noticed a large change when I started to turn up my brightness.

 

In order to make sure this is no hardware problem, you will have to reinstall Windows on a new partition, install all factory default drivers, turn off wireless, turn on power-saving mode, turn off auto-standby, and idle on desktop to see how long can it last. And what how does the battery decreases with time.
After that, you can delete the new partition, freeing up disk space.

If you suspect there are some programs such as virus, trojan, etc., you can look at Task manager what programs are using CPU abnormally. Usually, if you did not run any programs after a fresh boot, the task manager should show "system idle process" taking up 99% CPU. And your battery should NOT drain very fast in this condition if your power scheme is set to power saving. Otherwise, something is wrong with your laptop hardware.

 

Apologies for the delayed response. Something is stopping your CPU going into the lower power states. Here's the typical situation for my Dell E7440.


Are you using a maximum performance power profile?

When a computer is truly idle, you should be seeing the individual cores spending up to 99% of the time in one of the deep low power C States like C6 or C7 for the Haswell CPUs. When all of the individual cores enter the same C State, then the entire CPU package can also enter a low power C State for further power savings. C6 package or C7 package isn't a big deal. My Lenovo Y510P has left the C7 package disabled but at least the other package C States are enabled. Open up the Windows Task Manager and find out what apps are running in the background. I fixed one computer yesterday and it was the GoPro Studio - Notification Area icon that was using half the CPU, 24/7, when GoPro wasn't even being used. Every time you install a new program you have to make sure that your C State idle time has not significantly changed. Battery run time went way up as soon as that process was killed. Autoruns is very useful when disabling start up items that are really not necessary.
