UX31 wear level

I just received my ux31 3 days ago, and after having installed HWmonitor it shows that the battery has a wear level of 7%... Isnt that quite high for a completely new laptop?

 

Battery wear tends to show that amount on a new battery but then it will slow down. When I got my Asus June 2010 it showed 6% pretty much right away. A year and a half later its at 15%. This will change depending on how often you use your battery. With a 6% wear i wouldnt worry about it too much.

I received and started using my computer on November 22nd and have been using it exclusively everyday for at least 8 hours a day for the past 41 days. I play Minecraft everyday, so that loads up the CPU/GPU quite a lot. I also do the basics such as Microsoft Office, Skype, Pandora, email, web browsing, Facebook, and Youtube (I prefer plugged in & on high performance). I haven't been very mobile as of lately due to my school's winter break so I've been using the computer mostly with the AC adapter. When I am on the go, I use Power Save.

I use to leave the battery out of the computer when using the AC adapter with my HP Pavilion DV5. In the past, I have read and researched that leaving the battery out when plugged in is best for prolonging battery life. Leaving the battery in, meant possibly overcharging and overheating the battery. Apparently, not all batteries & computers are built/designed the same. That's when I read in the U24E manual that taking the battery out of the computer is NOT necessary after the battery has fully charged. There is a protection circuit inside the battery/computer that prevents overcharging or damage to the battery when the AC adapter is left plugged in. Since then, I no longer remove the battery while plugged in.

I wonder then why my battery already has such a high wear rate? It could be due to my usage patterns. Maybe I should fully charge and discharge the battery to condition it? What are you using to monitor the battery's condition?


Using PC Wizard 2010 v1.961 & Using CPUID Hardware Monitor v1.18.0:

Designed Capacity: 57200 mWh
Full Charge Capacity: 55726 mWh
Capacity: 55726 mWh (100.0%)
Level: 3%
Rate: 0 mWh
Voltage: 12.58 V


Using HWiNFO64 v3.91-1470:

Designed Capacity: 57200 mWh
Full Charged Capacity: 55726 mWh
Wear Level: 2.6%

Current Power Status
Power Status: On AC Power
Current Capacity: 55726 mWh (100.0%)
Current Voltage: 12.575 V


Has anyone else had the chance to test this?

EDIT: I've been watching this and I've concluded that these battery tests/results are not always accurate, especially when plugged-in. They are most accurate when on battery alone. When on battery, I've seen my Full Charged Capacity go past 57200mWh! And, my wear level is really around 0.0-0.3%. I will continue to monitor my battery but so far it has been flawless! I get 5 hours or more of battery life on average and have had ZERO problems with this battery. It is really a great battery and I don't think we have much to worry about.

 

I personally do not believe the results of this tools. Here is why:

I run HWmonitor on my 6 years old HP Notebook wear level is 0 (ZERO !). Yes, zero, nice...

I bought two notebooks: Toshiba R835 and Toshiba Satellite R835 (in fact same notebooks, first names for USA the other named for Europe).
HWmonitor says battery wear level is %9 (for both of them).

They are BRAND-NEW but the wear level is %9, 6 years old HP wear level is %0 !

So, I do not believe these results.

 

My Asus UL80Vt-A1 was purchased Jan 18th 2010 and HWmonitor shows battery wear level is 13%. Nothing to complain about there. I still get 7 hours + with wifi enabled, running Firefox with 28+ tabs, Thunderbird and my Excel spreadsheets and screen brightness around 25%.

 

Just because it reports 7% doesnt mean its correct. Its an estimate based on a full charge discharge cycle.

It will either stay 100% under discharge for longer than normal, or still run at 0% for a few minutes. Eventually it may settle back to 0 after several full charge discharge cycles.
