# **Four points to consider when buying a smartphone** **Except for some wealthy people, most consumers when buying a new smartphone want it to be usable for as long as possible. To achieve this, there are several configurations that users need to take care of.** Here are four configurations that users particularly care about when shopping for a smartphone, allowing them to use it for as long as possible. ## Large internal memory Basically, all smartphone manufacturers focus on memory configuration and technology parameters when introducing a product to the market, especially in the Android world. It can be 12 GB RAM + 256 GB internal memory, or 16 GB RAM + 1 TB internal memory… Both of these parameters have a big impact on the daily experience on smartphones. Besides, users should also pay attention to the specifications of the memory, in which the larger the following digit the better. For example, UFS 4.0 flash memory will definitely give faster data access speed (doubling) than UFS 3.1… With RAM, the memory specification can be LPDDR5X… Studies have shown that, if the memory is not enough, the system will have to shut down processes to reduce latency as well as unilaterally close background apps. As users install more and more apps, the available memory will shrink, especially for Android phones. Therefore, users are recommended not to choose a model with 8 GB RAM or less because after a year or two of use it may be worse, must upgrade to have a better experience. In addition to background applications, taking pictures, etc., which take up a lot of memory, users only need to know that low RAM will cause the game to be “killed in the background” when returning to the game. However, as the world of technology has grown, this problem is said to have been much reduced. ## Powerful performance If memory is the most notable hardware configuration, the mobile chip is equally important. The refresh rate of this core hardware is very fast and the chip can upgrade 4 or 5 times in just 1-2 years, with each time CPU and GPU performance can be improved by about 20%. But the performance requirements of the application will also become higher and higher, so the mobile chip must be powerful enough to ensure the smooth operation of the smartphone. If you still want to play mobile games, the chip requirements are even higher. It is recommended to choose the most powerful chips in the Android world, such as Snapdragon 8 Gen 2, Dimensity 9200+… According to the development speed of mobile chips, they can ensure strong and stable performance for at least 2-3 years. ## Good system Smartphone manufacturers all have their own custom systems with the latest algorithms and technologies built in to slow down the aging process. For example, Oppo’s ColorOS platform can accurately schedule hardware resources and focus on solving two industry problems, irrational resource allocation and memory usage conflicts. Of course, there are many smartphones that have received the same anti-aging certification and all of them deserve priority. ## Battery stability Over time, smartphones become less and less efficient due to many reasons, for example iPhone used to have problems with poor performance when the battery condition decreased. To use smartphones for a long time, users should also pay attention to daily usage habits such as unplugging the power when the back cover of the phone is becoming too hot and do not wait until the battery is exhausted to recharge, but instead charge whenever possible. Some smartphone manufacturers are also investing in battery research and development, such as Xiaomi’s self-developed G1 chip or Oppo’s SuperVOOC… which can effectively optimize the charging and discharging process, thereby helping to prolong battery life.
