Laptop battery drains quickly, even when turned off.
Zaz -
Good evening,
I just bought a laptop, a Dell Latitude 7400 2-in-1, which is recent (2019) with good specifications.... I got it in perfect refurbished condition, I know it’s not worth as much as new, but on the Dell website, they advertise a product with over 20 hours of battery life... However, mine lasts around 6 to 8 hours with school-type usage (Google and Libre Office...). If that were the only problem... It’s mainly that I charge it to 100% and shut it down, and by the time I get to class (10-minute journey), I arrive with between 85% and 75% depending on the day. The battery drains on its own, it honestly drives me crazy. I contacted Dell to check the battery status, it shows "excellent": the battery is in good "condition". I’ve already disabled fast startup, lowered the brightness, etc.... I don’t know if my laptop is completely defective, or if I’m missing something? Maybe a setting to disable (I hope...). I’ve seen something about battery charging while off, but I didn’t really understand... I’m really open to anything and everything! Thank you in advance :)

Hello Zaz,
First, you might have the fast startup feature enabled on your Windows, which means that if you turn off your PC, it goes into a "deep" sleep, and when you want to turn it on, Windows starts up faster than usual. The consequence here is that it consumes battery percentage. I refer you to Lenovo's website for the tutorial on how to disable it (sorry, I can't share links at the moment) How to enable or disable fast startup on Windows 11 - Lenovo Support SV.
Secondly, if you have peripherals connected to your PC (mouse, USB stick...), it’s a cause of battery consumption. So, try to unplug what you don't need when you're not using your computer.
And thirdly and finally, consider whether the PC is not being used, as the more it is, the less reliable the battery state is (+/- reliable) (generally, it’s like that). If none of the solutions resolved the issue, I think you should change the battery (here's one from Amazon (sorry, I can't share links. Here’s the name) -> K KYUER 60Wh MXV9V Battery for Dell Latitude 5300 5310 7300 7400 E5300 E5310 E7300 E7400 Inspiron 7306 2-in-1 P96G P97G P99G P100G P97G001 P97G002 P100G001 D1XK9 829MX 5VC2M 0829MX 05VC2M 451-BCJG for 47 euros).
In the meantime, I advise you to use the battery saver ;)
Best regards,

Good evening again,
I have already disabled fast startup (as I mentioned in my message), regarding the devices, I am not using any.
The battery is not worn out because as I said, I went into the BIOS to check the battery status and it says "Excellent". So should I change it in this case? It's strange...
My computer is still in battery saver mode but it drops very quickly (5% in less than 10 minutes of LibreOffice).
Thank you for your feedback.
Hello,
Interesting. A few questions: is your PC overheating? Have you changed any components (RAM, hard drive, etc.)? Is there any obstruction in the ventilation? Are you sure your PC is not going into sleep mode?
Check to see if there are any drivers to update.
Otherwise, if none of these solutions work, even though the battery status shows "Excellent," it could be in poor condition.
Best regards.
Hello,
So, it doesn't really overheat that much, even though it's true that sometimes it gets warm even when I'm not using it heavily; it's just a bit warm, nothing more. Sometimes it does make some noise, a slight whistling for example when I plug it in with my charger usually. And no, I haven't changed anything, it’s "new," I've only had it for a week.
Thank you for your replies.

Hello,
Try executing this command:
Open PowerShell and:
Powercfg /batteryreport /output c:\reports\Battery.html
This will create a file Battery.html which will be located in C:\reports.
Thank you for sharing it with, for example:
Or others...

Hello, you probably need to create the directory C:\reports and/or run the command in administrator mode.
This report is often interesting. I have a 2019 Dell Inspiron 7586 2-in-1, and it shows for example the original battery capacity and its current capacity:
DESIGN CAPACITY 41,998 mWh FULL CHARGE CAPACITY 31,179 mWh
It has lost a quarter of its original power. And in the following table, there are the usages for the last 3 days.
-
No, the 70% is due to the aging of the battery. It no longer has its original capacity. Even when fully charged to 100%.
Change it? Maybe. But personally, I would have doubts about the 20 hours of battery life.
And if it's like my laptop, the battery is not removable. You have to take apart the bottom of the laptop to replace it, if it's even possible. -

Hello
a Dell Latitude 7400 2-in-1, which is recent (2019)
2019.....it's not recent at all......
5 years for a battery, depending on its usage, is already a good age; if you still get 6 hours on battery, you actually have no problem.

Waiting for more responses; I'm attracting trolls....
