Disable Bluetooth, location, and WiFi automatic search functions
Don't look at these small functions, but also very power consumption. In terms of WiFi automatic search, there is no WiFi environment, but the WiFi switch has been turned on, then your phone will continue to search for WiFi, and this process will definitely eat the phone power! So turn them off.

Don't wait for your phone to run out of battery before charging it
When we think about how to save electricity, protecting mobile phone batteries and improving the battery life of mobile phones is the most important thing. Lithium batteries can be charged at any time, in order to reduce the number of charging and deliberately use up the battery and then full, has a negative impact on the life of the battery. Therefore, do not wait for the phone to run out of power and then charge it, which is very damaging to the phone battery.

Smart phones, like personal computers, have independent operating systems, independent running space, can be installed by the user, such as software, games, navigation and other third-party services provided by the program, and can achieve wireless network access through mobile communication networks. At present, the development trend of smart phones is to fully join a number of patented technologies such as artificial intelligence and 5G, making smart phones the most widely used patented products.
Smart phones have excellent operating system, free installation of all kinds of software (Android system only), full touchscreen operation sense of the three major features, of which Apple (Apple), HUAWEI (HUAWEI), SAMSUNG (SAMSUNG), Nokia, HTC (HTC) these five brands are the most widely known in the world. And Xiaomi (Mi), OPPO, MEIZU (MEIZU), Lenovo (Lenovo), ZTE (ZTE), Coolpad (Coolpad), oneplus (oneplus), VIVO (Vivo), Tianyu (Tianyu, K-Touch) and other brands have attracted much attention in China.

The world's first smartphone, the IBM Simon (Simon Personal Communication Device), was born in 1993, and it was manufactured by IBM in partnership with BellSouth. As an emerging technology,
Apple and Meizu CDMA CDMA2000 are rapidly gaining popularity around the world and already account for 20% of the wireless market. As of 2012, there are more than 256 million CDMA2000 subscribers worldwide, and 156 operators in 70 countries have commercialized 3G CDMA services. Dozens of Oems around the world, including Anxin Communication Technology Co., Ltd. with Qualcomm's authorized LICENSE, launched EVDO mobile intelligent terminals. In 2002, Qualcomm's chip sales hit a record; Since 1994, Qualcomm has supplied more than 7.5 billion chips to many manufacturers around the world, including China. Smartphones were born in this context.
The application software of different operating system mobile phones is incompatible with each other, and the mobile phone software of the same system is basically universal and convenient to use. Because third-party software can be installed, smartphones have a wealth of extensibility features.
The birth of the smartphone is the evolution of the PocketPC. The earliest handheld computer does not have the function of mobile phone calls, but as users rely on the personal information processing function of the handheld computer to improve, and are not accustomed to carrying mobile phones and PPC two devices at any time, so manufacturers transplant the handheld computer system to the mobile phone, so the concept of smart phone emerged. Smartphones have more integrated processing power features than traditional mobile phones, such as Symbian OS S60 series, Symbian S60, Symbian3, and some MeeGo OS smartphones. However, in terms of recent developments, there is a tendency for these smartphone types to merge.
Smart phones are similar to traditional mobile phones in appearance and operation, including not only touch screen but also non-touch screen digital keyboard phones and full-size keyboard phones. However, traditional mobile phones use closed operating systems developed by manufacturers themselves, which can achieve very limited functions and do not have the scalability of smart phones. The term \"Smart phone\" is mainly for the Feature phone, which does not mean how smart the phone is; From another perspective, a \"smartphone\" is a phone that can be installed and uninstalled at will (just like a computer). Feature phones are not free to install and uninstall software

The emergence of JAVA has enabled later feature phones to install JAVA applications, but the operation friendliness of JAVA programs, operating efficiency and the operation of system resources are much worse than smart phones.
The world's first smartphone was the Simon, launched by IBM in 1993. It was also the world's first smartphone to use a touch screen, use the Zaurus operating system, and only one third-party application called \"DispatchIt\". It has laid the foundation for future smartphone processors and has milestone significance.
The first iPhone was released in 2007, and on July 11, 2008, Apple introduced the iPhone 3G. Since then, the development of smart phones has opened a new era, and iPhone has become a benchmark product leading the industry.
Large-screen phablets are becoming mainstream, with shipments surpassing those of smaller tablets in 2014.
