Battery Life on 13-aq0004np

[InfinisEternum]

Hi,

I've recently acquired an HP Envy 13 (13-aq0004np model), and no matter what i do i cannot get more than 4h20 of battery life, even if i leave the laptop on, in battery saving mode, idling.

I've done all updates, including the BIOS one to the latest F07 to no help. I've also tried a clean OS install to no avail.

More data: HWinfo reports a battery draw of 12335mW no matter which state i leave the laptop, which translates to the 4h20m of battery life I'm experiencing, so it looks more of a software/firmware issue than a hardware issue.

Any ideas?

@InfinisEternum Here's what you need to know about how the battery typically drains:

That said, what do you use the device for, is its most gaming or for watching movies/videos, the battery could drain a lot faster than it would while editing a document or simply going through pictures on the device.

If you've been using the battery for simple tasks as mentioned above, you may want to perform the below steps to enhance the battery performance:

The first thing you'll want to do is make sure that you have a reasonable power plan selected for when you're rolling on battery power. The high-performance plan is always tempting (you're a high-performance user, after all), but you'll burn through your battery a lot more quickly, so select the Power Saver or Balanced plans, and make sure it's set to turn off the display quickly after inactivity, since that's the biggest power drain.

Next, you'll want to dig further into the Advanced Power Plan settings, and make sure that the On battery settings are set to maximize battery life—change the plan to turn off the hard disk quickly, use the low-power mode for your wireless adapter, processor, and especially your graphics card. The System cooling policy setting allows you to specify whether the laptop will rely on fans for cooling, or slow the processor down when the temperature gets out of hand, and can definitely help your battery life, though at the cost of some performance.

Adjust the Screen Brightness

Since we've already shown that the LCD screen is the biggest drag on your battery life, the quickest way to save your battery life is to use your laptop's hardware buttons to control the screen brightness—most laptops require holding down the function key and using the brightness keys, and turning it down as far as you can (while still visible) is a good idea. It may seem like an obvious choice, but it's worth emphasizing at the top of the list for one reason: Of everything you can tweak to improve your battery life, this one change alone is at the top of the list of tweaks that can dramatically improve your battery life.

Make sure that your power plan is set to turn off the display quickly when your laptop is idle, and don't use any fancy screensavers that overuse the graphics capabilities of your laptop. Many websites tell you to disable Aero to squeeze more battery life, and it's true that you might get a very small bit of extra life, a couple of minutes at the very most—you will be much better off adjusting the screen brightness and using aggressive screen blanking settings.

Kill Background Processes and Services

Runaway system processes can do more than just kill your PC's performance—they can also kill your battery as well. You'll want to make sure that you close any background applications you don't need to be running while you are on battery power, and disable any automated updates, scheduled tasks, and especially search indexing.

Prime targets for removal are things like Windows desktop gadgets and all of those applications that hide in your system tray. It's time for a cleanup, so disable or uninstall any application running in the system tray that you don't actually need. (Only uninstall if you're still plugged in—no use wasting extra battery life on that now.) It's not just good for your battery life, it's a good practice in general.

And last but not least, if the issue persists, reinstall the battery drivers by uninstalling the same from the device manager and get back to me with the results,

P.S: Welcome to HP Community 😉

Keep me posted, as I (Or a trusted colleague) shall follow-up on this case to ensure the concern has been addressed, 

And your device is up and running again, only in case you don't get back to us, first!

Thanks for the answer, and sorry for the long time to get back to you.

I've tried numerous solutions including the ones you mention but I keep seeing the same discharge rate, and the battery lasts the same time.

I believe this might be a firmware/software issue since the battery drain reported is always the same independently of what I do with the laptop. I'm using throttlestop and batterymon to verify and I keep seeing the laptop reporting a 12,335w of drain.

The user of this post reports the same https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/I-can-only-get-around-4-Hours-... can you let me know what was the solution for him?

Thanks.

@InfinisEternum I checked the link you mentioned, and the private message is for contacting phone support in case you need a battery replacement, although, we don't have to do that just yet.

I suggest you perform a test and calibration of the battery: click here for details,

If that doesn't work or it fails, you may need to get the battery replaced.

If that passes, we may need to test the adapter: click here for steps.

If you wish to thank me for my efforts, you could click on "Accept as solution" on my post as the solution should help others too.

@Riddle_Decipher both tests are reporting OK.

I have an update: Occasionally, when returning from standby, either by opening/closing the lid or the laptop going into hibernation, when the laptop wakes up the battery discharge rate lowers. This suggests that there is a device that is erroneously powered while on battery that sometimes doesn't resume when the laptop wakes up.

This lowers the discharge rate from 12.3w to 4.9w and the battery life increases accordingly.

I have a few questions:

1. Can you report this internally? sounds like a firmware/driver issue.

2. Is there a way I can see which device is powered on and causing this drain?

Thanks.

Many laptops use the Connected Standby feature, and this feature won’t completely turn off your laptop. Instead, it will keep it in a state similar to Sleep Mode and allow you to easily boot your Notebook

Although this feature can be useful, it might drain your battery even while your laptop is off. To fix this problem, you need to disable this feature by making a few adjustments in your registry. 

1. Press Windows Key + R and enter regedit. Now press Enter or click OK.
   
2. When Registry Editor opens, in the left pane go to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power In the right pane, double-click the CsEnabled DWORD.
   
3. Set the Value Data to 0 and click OK to save changes.
   

After doing that, restart your Notebook and let me know how it goes

The Connected Standby feature is working indeed as it should. If you read my posts from the beginning you'll see that my issue is drainage during laptop operation on battery and not while on standby.
