Battery wear level (Lenovo C930 Glass)

Hello everyone,

first of all my apologies if I did not post in correct sub-forum. Feel free to move my thread if necessary. I think this is more tech-related question than Lenovo related... but you decide

I am writing here desperately to see if I am crazy or Lenovo is crazy.

So, in 07/2019 I have bought Lenovo C930 Glass. In following weeks I was following how my notebook is performing and I have noticed increasing in battery wear level (measured in HWmonitor, Lenovo Vantage and Lenovo battery report via CMD). Battery wear level was up to 6%, I have emailed my local Lenovo service partner and after couple of days they have informed me that Lenovo approved battery replacement (without any additional tests, at the wear level of 6%). This was in 10/2019.

And you must be curious what is the problem?

Long story short: new battery after couple of days of usage started losing it's capacity. Now, in 04/2020 wear level is about 25%. That means I have lost 1/4 of the capacity of 2000 USD worth notebook in just 6 months (since 10/2019). Maybe this is joke to Lenovo, but it is no joke for me.

Lenovo now changes approach: it is no longer important that my wear level is 25%, now they say that only relevant information is status of the battery in Lenovo Vantage (status says "Battery is in good condition"). But why they did not ask for this status in 10/2019 when they approved battery replacement just via email communication without any testing at wear level of just 6%? Strange...

Current situation:
Full charge capacity: 47890 mWh
Designed capacity: 60060 mWh
Wear level: 21%

Can someone experienced please advise me what to do?
Coud charger be the problem?

Thanks so much for any kind of valuable feedback!

...seems to talk about the sudden drop of Battery strength.

 

But my problem is not poor battery life due to battery drain.

The problem is battery wear level (battery that obviously cannot be charged at full capacity and works with limited capacity, much less than in specifications).

Thank you

 

Fast Charge and Fast Drain of battery can contribute to wear of battery.
And, in addition, most companies may not use factory "Sealed" fresh batts for replacement. Just in case certain batches hv explosion/burn issues.

 

How to convice Lenovo that something is wrong?

1/4 of battery capacity less is "wrong" for me.

 

Return it as soon as you can. Don't put up with that crap. You clearly have a faulty battery, unless you are operating your alptop in excessively hot conditions or are charging your laptop fully and discharging it multiple times every day

 

Hello, thanks on your reply... I got approval for new battery replacement. So... here we go for the second time.

Of course I am not fully charging and discharging.

If I got two faulty batteries already, what is the change that third will be okay? I am very skeptic

 

My device scheduled for battery, motherboard and AC adapter replacement.
