One thing that is the main concern of every laptop user is whether or not their battery will last long for them to finish an appointed task.
It has been found that manufacturers of laptops tend to exaggerate their battery life, but measuring it meaningfully can be challenging.
Trusting the processor speed or memory capacity on the specification sheet of your new laptop is a relatively safe bet, but when it comes to the battery life, how much can you estimate? Some manufacturers’ claims about how long their laptops can go without a charge are overstated.
Some battery tests carried out by the United Kingdom-based consumer products review website suggests that some laptop makers claim a battery life that’s 50 percent longer than their batteries last under real-world conditions.
Among the verdicts is that the Dell Inspiron 15 5000 lasted just under four hours, despite Dell’s claims by Dell that the laptop battery can last up to seven. At the other edge of the spectrum was Apple’s 13-inch MacBook Pro, whose battery used up to two hours than Apple advertised.

The company made it cleared that they believe that the tests they conducted are a true diplomat of the real world use that a laptop would get. They also concluded that the figures they came at are often drastically different to the manufacturer claims, which makes us wonder how they arrived at their estimates.
Of course, the discrepancy between an independent battery life test and a manufacturer’s claim is only an obstacle for you, the considered computer owner, whether or not your “real world” use matches the tester’s “real world.”
What this means is actively browsing the web over a Wi-Fi connection until the battery is drained. There are lots of variables in such a scenario, though, including the browser version and the individual websites accessed during the test.
Knowing that each user subjects their laptops to different tasks throughout a typical day, the standardized test made use of a standardized battery rundown test that helps all operating systems, including Windows, Chrome OS, Linux, Android, and also OS X.
The report shows that for the 13-inch MacBook Pro which went for 11 hours and 53 minutes followed closely with those from other independent testers. Also, it was found that the Inspiron 15 5000 lasted 5 hours and 8 minutes, about an hour longer than some independent inspectors claimed.
Nonetheless, Dell has so far not made any specific battery life claim on the Inspiron 15 5000 websites.
