I have checked the BIOS and run PC Diagnostics (from the website and from Pre - Boot. They both say the battery is performing normally. Is there any more suggestions? Thank you.
I apologize for the delay in response! I would suggest you to try updating the BIOS to latest version.
**NOTE: Few things to ensure before updating the Bios is, the Ac Adapter should be plugged in and the battery should have minimum of 15% charge. No other external peripherals should be connected to the computer. Please ensure that the Bios update should not be interrupted else it would damage the motherboard.
Hope this helps!

Awaiting your response!
I have been facing exactly the same issue as mentioned above. This issue is occurring from the very 1st day I received the laptop.
I have updated BIOS, calibrated the battery, ran diagnostics, some representative from dell disabled all third party services but the problem is still the same.
On full charge, it shows a time of approximately 11 hours & reduces to 5hrs/3hrs after a restart.
I do not understand if this is a hardware problem or a software problem as many people are facing this issue with this specific laptop.
I have bought this laptop on 29th August 2013 & have not really got a solution which would resolve this issue.
HI, i just got an Inspiron 15R 5521 today, my time remaining on my battery shows 216 hrs. at 86% battery life. Any suggestions other than those given...tried them and nothing has changed.
