Inspiron 15-3521, Battery questions

Hi Guys,

I just bought a new Laptop (Dell Inspiron 15-3521) but it does not keep charge. Before I sleep I charge it to 100% and shut down my laptop. But when I wake up in the morning and switch it on, it says battery low. Is my battery genuine? My batter number is: DSH2016032120053. Made in China. Please I need to know if the problem is the battery or not by checking if it is genuine. Thanks alot.

If purchased directly from Dell, the battery is genuine. If not, no way we can know what the reseller may have done.

Sleep/Wake is not a true power off. You should click Start- Power- Shut down. Then test.
