Abnormal Battery Consumption

My XPS L502X is 5 year old and naturally when the battery drains abnormally, first solution would be to replace the Battery with a new one.

However, issue is that even after Battery replacement, when i keep the laptop switched off overnight, i see a drop in battery charge % upto 25% i.e. from 100% to 25%.

To strike off possible root cause, i charged the battery to 100% , removed it from laptop and kept outside for 1 week. Observation was that the charge dropped from 100% to about 96%. Absolutely Normal. Therefore, i have ruled out the battery.

Any solutions on this problem of abnormal battery consumption even though Laptop is turned off ?

    It's still probably a battery that's worn out.  When the battery is in the system, even powered off, the system does use battery power -- when it's out of the system the battery isn't being used.  That slight power draw is rapidly draining the battery - in other words, it's worn out.

    Well i did check up with the service centre and they replaced the new battery with another new battery.

    Issue still persists. After i charge the laptop to 100% and switch it off, i see a drop by 12% in the battery after 24 hours. Now, this is really unusual for a brand new battery once again.

    Did you try recalibrating the battery monitor? Use the lower process for your lithium ion battery:

    www.dell.com/.../soho_article_8

    After you discharge the battery to 40% and recharge, run a battery health report

    With an elevated (admin) command prompt type:

    powercfg /batteryreport

    It will save the report in your c:\windows\system32 folder by default.

    No reason you couldn't run the report before and after calibrating the battery.

    If you are still having trouble, make sure your system is on the balanced power plan.

    There is also a chance your new battery is a dud.

    Well i did the above mentioned steps. Report shows everything normal. But absolutely no resolution in this problem.

    I have got the battery replaced twice. Battery would be dud in both cases ? Dell should stop selling dud batteries then.
