IdeaPad S540-14IML battery life

2020-08-29, 12:37 PM

I think I have a problem with the battery life on this model.

 

I also I have an IdeaPad 5 14are05 and the battery lasts much longer.

Hello,

 

Please expand more explanation regarding what is happening with your battery.  Also, is your problem system under Warranty?  If it is under Warranty, use your mouse, select "SUPPORT" at the top of this page, type your system serial number into the window.  This will open a page describing your exact system configuration.  You will need that to answer my next question.  If you have Warranty coverage, click the contact warranty support button, and talk to that team.

 

If you don't have warranty, how many Watt Hours is your system battery rated?

 

For example, my system has a 30 watt hour battery.  My system usually uses a little more and a little less than 10 Watts.  If I try hard to minimize screen brightness, make the processor fast to sleep and so forth, I can get my system down to 7 Watts usage.  From fully charged to fully discharged my 30 watt-hour battery will supply 10 Watts for 3 hours.  It will provide 7 watts for 4.29 hours according to my calculator.  It is a simple algebra division of how many watts times how many hours add up to 30 Watt hours.

 

Batteries degrade with age, so when my battery drops to actually providing 15 Watt Hours of storage or 50% of original capacity, I'll think about replacing it.  IF you are hard on your battery, or unlucky this could be as soon as 14 months from new.  I think I treat my battery kindly, so far mine still has 95% of capacity after 3 years.

 

Sincerely,

Usedtoberich

It is a 7-month-old laptop with a battery (15.44V50Wh4cell) that had only 16 cycles. I sent it under warranty and the battery was replaced. The original battery was produced by Celexpert and the new battery is produced by SMP. I just received it and I'm waiting to see how it behaves.
