Battery wear level on Lenovo notebooks? Please contribute!

Hi everyone,

could you PLEASE check your battery wear level and update us here? It won't take much of your time, but it can help some of us get justice.

Notebook model:
In use from:
Battery producer (if you know):
Battery wear level:

I am in a conflict with Lenovo trying to prove them there is something from with the batteries. A lot of resources (Lenovo Forum, Reddit) suggest that there are a lot of unadressed issues.

In my particular case this is already second battery. First one was replaced on 3rd October last year... and this one will also get replaced soon. Very frustrating!

To check wear level please download HWMonitor and open it: https://www.cpuid.com/softwares/hwmonitor.html (very small software, no garbage in it).

So, allow me to start.

Notebook model: Yoga C930
In use from: 3rd October 2019
Battery producer (if you know): Celxpert
Battery wear level: 28%

Thanks everyone in advance!

 

Notebook model: ThinkPad P1 20MD
In use from: 1/15/2020
Battery producer: Celxpert
Battery wear level: 5.6%

BTW, @Keano16, you may want to edit your original post to add instructions for people who may not know how to look up their battery wear level.

 

Thanks for the suggestion. I will edit my post.

 

What is the point of collecting such data when there is no reference point? Everybody uses their notebook and battery in different way. It is like collecting data on number of broken cars without stating if the break occurred in factory, shipping, misuse, collision, accident etc.

 

Well, TS is probably trying to pinpoint on specific battery maker, towards specific production batch of batteries. But he had probably ignored that his 2in1 flipper is that slim that heat dissipation design could be a flaw that contribute to the fast degration of his battery.

 

If the battery has a flaw then sure, Lenovo should swap it for new one.

But we don't even know how Keani16 is using his battery, maybe he is discharging it from 100 to 5% every day and therefore murdering his battery. If that's the case then nothing will help beside changing usage scenario.

Posting data without reference point just doesn't make sense and achieves nothing IMO.

 

Hello,

I got your point, but still it does not prevent you from contributing and posting your data. Maybe it will help me or someone else, and it will take just 3 minutes of your time.

In this matter I am counting on everyone's rational use of their own system and battery. Of course that does not need to be right. But, the data I collect will suggest certain things to me. For example, if your battery is only 2 months old, you use it improperly, and it has 30% wear level - then 30% is too much even if you really use it improperly because it is just 2 months old. Long story short - the data I am trying to collect IMHO is enough.

For the reference - I am using my device very carefully. No full discharging. I am not killing my own battery. Batteries are bad or something else is the problem (device design, charger, batter controllers, firmware?). I don't know.

Lenovo already replaced first battery. Now this one also has problems and I am waiting for the third battery.

Be so kind and contribute with your data, please. Thank you.

 

Hello and thank you,

I did not ignored that fact. For this reason I have spent the weekend studying Lenovo Community (Forum), this forum and Reddit. As I can see - there are many Lenovo users with different devices (2 in 1, normal notebooks) which have very similar problems.

This is why I think something is wrong with the battery. Maybe CelXpert problem. Maybe SMP batteries are better? Who knows.

Best regards!

 

Unfortunately I can not post my data.


Second thing I did after creating factory disk image and fresh Win10 install was to remove internal battery from my unit.

Also, Lenovo bios update tool requires battery to be connected to the MB in case anyone would want to remove it and then try to update bios. For me at the moment is not a problem unless very significant update will be published.

 

There are many factors that contributes to heat built up, and the speed of cooling off to prevent overheat of the battery. I believe that Lenovo sources their batteries from different suppliers, towards specific specs given by Lenovo across on their specific product range. So far, @CitizenInsomniac had shared his ThinkPad P1 battery was made by the same manufacturer as urs, u could take it as a reference to compare with urs on size and built. I can give u my share with my L340-17, which is much bigger than ur C930, however that will be later when i reach home in few hours time...

 

Thank you Ed. Yang. Update me when you can

 

Just a glance into ur cramped system...

...it spells a easy heaty system that will stress ur battery...​

 

I saw this online and in service manual aleady. Thanks.

Obviously I did a big mistake when buying this device, such an expensive one! Now there is no way back... The only hope for me is the fact that there are users with this device who have NO problems with battery wear&tear. That kind of suggests:

- user problem (improper battery management and charging)
- battery problem

If we can trust my words (what could be the reason for me to make all this up? ) ... then battery is the problem (or device... but not the user).

 

Okay... Here's my result.
Battery maker: UNKNOWN(CPUID's HWmonitor displays as L18M3PF2)
Battery wear lvl @ 4%

 

Thanks
