All laptop manufacturers except Apple, 2-3 times overstate the actual battery life

According to the study, the largest time web surfing on a single charge boasts a MacBook Pro laptop – 12 hours. According to the researchers, Apple is the only manufacturer that underestimated the real battery life of the laptop. For most other models, the battery life is 2-3 times lower than claimed. For example, device 510 according to the description should work 5 hours, but lasted in tests only 2 hours and 7 minutes and the Dell Inspiron 15 5000 is 7 hours and worked 3 hours and 58 minutes.
