Battery life issues

[goatedpenguin]

Hi I recently purchased the HP Envy Laptop 17t-cw000, 17.3" and its battery life to say the least is not where it should be. Now before you tell me to update the drivers, bios, uninstall the acpid & AC adapters drivers from device manager, reboot the machine and  also run diagnostics, I have done all that. I have also ran the hp support assistant diagnostics and it tells me everything is normal. And no I am not running anything intensive, the most intensive thing would probably be WSL and besides that everything is done on the browser etc. And if your going to say that WSL may be the cause it is not, in fact this is not OS specific, I had installed arch Linux on this system but decided to go back to windows and the battery life on both OSes was horrible, so no this is not a software issue or a bios issue it is most likely in my mind a hardware issue. Any thoughts on what might the problem be? The computer is great and the keyboard, audio, trackpad is such a joy to use but the battery life needs to be fixed.

And also please don't tell me to do sfc /SCANNOW that command never works .

Thanks in advance 🙂

Wasn't going to suggest any of what you rule out. But be specific. How much life are you getting vs. what do you expect? 

You do not give the exact model but it has a huge screen and likely a powerful CPU and maybe a dedicated video card. 2.5 to 4 hours is a reasonable expectation. Less than that and you may have a bad battery.

Hi I am sorry for sounding blunt, its just that I have read a lot of forum posts here and many people who try to help give some cringe sounding compliments and bad advice like "kudos to you for trying the superb diagnostics etc." and then they give a bunch of advice that never works. Responding back to your question the battery does seem to last for around 3 hours at best. I understand this computer is pretty bleeding edge and is very high spec but my expectation was around 8 hours. like litterally right now I just unplugged the computer which was charged to 96% and it went down to 94% in like less than two minutes which is bit odd imo.

The specs for the laptop are:

Intel i7-13700H

32gb ram@3200 mhz

windows 11 pro

17" screen

EDIT: battery is now 79%

2 kinds of responders here. Fellow end user experts like me who do not work for HP and HP Agents, who are shall we say more constrained in their ability to respond candidly and tend to work off scripts and checklists. 8 hours is not a reasonable expectation for a 17 inch laptop. 3 hours is par for the course and could perhaps be improved a bit. Biggest improvement can be achieved by limiting screen brightness. The screen takes the most power and after that is the video card, particularly if you have a dedicated one. 

Good luck

Hi thanks for giving all the info I will be sure to tweak the brightness and the power settings etc. Thanks for all the help 🙂

What irks me is that on the purchasing page- the battery life was listed as 9 hours... even with light web browsing- the most I get is 3 hours which is a bit off expectations. Am I doing something wrong? As OP said I've tried all the common advice (even tried running Linux like OP) but to no avail. If I can't improve this I'd probably just return this and buy something else.

Ye my expectations were much higher but I suppose the hardware and the screen this laptop has would cause the battery to die out rather quickly.

You may well be right 2 to 4 hours, but the boasts by HP themselves on their Envy laptops (2023) is some 8 to 10 hours watching video. Nope nowhere near that and truly false advertising.

Yep sent one back and replaced so X2 same issues. Simply on both, running 50% brightness and not videos gives a life of 100% to 20% (saver turns on then) of 2hrs 15 mins and 2hrs 40 mins respectively ...3 hours or just over then laptop turns off at around 4 or 5%

Next test running now is simply with battery saver on from start and 3 hours in with usual light use (no video or gaming) sees 39% left after 3 hours. One could 'assume' it may get 4 to 5 hours at this rate.

However, 10 hours is just plain BS and is on HP store reviews ..how could you achieve that? Stop every single background app and watch videos on 0% brightness setting?

Poor show HP

This is one of those topics where it just does not pay to respond when the advertising says 8-10 hours and that is just not realistic. But its not just HP. Check battery life claims for all laptops. Some brands may have a bit better power management but nobody gets 8 hours from a 17 inch laptop with dedicated video and a top tier processor. Don't shoot the messenger; I am not an HP employee.
