Lenovo flex 5 14 4500u, full charge capacity going down too fast.

2021-05-04, 13:02 PM

As explained above, My laptop only saw around 60 cycles and that's what all the different software reports (lightly used, some weeks not used at all) 
I also don't rapid charge to 100 and often charge just up to 60 for the health of the battery. 
It went down from 53,870 mWh full charge capacity to 48,020 mWh in 60 cycles (to be fair, I own it for like maybe even a year but as I said there were easily 6 months that it wasn't used more than one or twice a week for an hour as I used my desktop during lockdown) 
The amount of cycles is what you would get after 2 months if you were using it daily and often like most people. That's why I'm worried. 
Let's do some quick math, if two months made it lose 10%, 20 months would make it lose 100%? this means that after a bit more than a year and a half, dead laptop. Not reasonable. correct?

Again, I need to mark this: Even if I have owned the laptop for almost or even a year that does not mean it has seen what is a year of usage because, again. 60 cycles. 
here's the windows report:

It's straight up copy paste, nothing changed. 
Correction*** I'm reposting this problem because I wasn't answered back on my previous time here regarding the problem, it's been about a month since and checking now it's not 60 anymore but 75. Makes sense because I'm back at school and taking my laptop with me. 

Anyway PLEASE don't ghost me after leaving a not solving reply. I really need support here to figure out what's going on. 

Also check screenshot please!

Hello LazyLand,

 

The battery life endorsed for the unit depends on how the machine is being used, what kind of programs are being utilized, the environment where the machine is mostly utilized, and what applications are running in the background.

 

Battery normally deteriorates at some point in time when all of its resources are used up, hence, this component is considered as a consumable part.

 

But you can check here and here for some tips to save battery life. 

 

Otherwise, you can try to uninstall the battery drivers and see if there would be any changes in the performance.

 

1. Open the Device Manager.
2. Click Batteries to expand it, there are two items: Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery.
3. Right-click on each item and choose Uninstall device. Yes, you are uninstalling your laptop's battery drivers, these will automatically be reinstalled when you restart the laptop.
4. Shutdown/restart the machine.

 

Regards.
