Smartphone users have more than oncereasonable questions regarding the declared technical characteristics of smartphones, which do not always correspond to the indicators advertised by the manufacturer. This is especially true for the autonomous operation of smartphones, and this is what the UK Consumer Protection Society noticed. It turned out that among the most dishonest manufacturers stood out Apple and HTC.
Experts checked dozens of autonomous workunits of smartphones in talk mode. At the same time, 9 iPhone models did not correspond to Apple’s stated technical indicators for battery life in talk mode. Thus, the iPhone XR in the "conversational" mode worked 16 hours and 52 minutes, while Apple guaranteed 25 hours of continuous conversation. At the same time, depending on the conditions of testing, the figures were lower than those stated by 18–51%.
HTC has shown a slightly better result. The specialists did not indicate which models were tested, but said that instead of the stated 20.5 hours of continuous talk, the HTC device worked only 19.5 hours.
Simultaneously, mobile gadgets suchmanufacturers like Nokia, Samsung and Sony showed results that surpass passport performance. For example, Sony Xperia Z5 Compact allowed to talk for 26 hours, while the company announced 17 hours of battery life.
Meanwhile, developers from Apple and HTC right awaythey firmly answered the experimenters, indicating that no clear test conditions were announced, not even the type of calls (mobile or via Wi-Fi), the types of device firmware, background applications and the number of tests.
Apple representatives said the companyThere is strict control over the testing of products, and especially the high demands on the battery life of the iPhone. In addition, intelligent energy management has been developed, which should, in practice, lead to the extension of the work of the smartphone offline.
HTC has noted that all product parameters are being thoroughly tested, but various settings and a testing environment may lead to some differences in technical indicators.
