　　Which brand of mobile phone has a long battery life? This is a very good question. Because the battery capacity of most current smartphones is not high, consumers often run out of battery capacity after a day of use. While performance and photography are getting better and better, it is becoming more and more difficult for mobile phones to have enough power for a day. Relatively speaking, Android phones last longer than Apple phones. In addition to Android's large battery, it is also because of fast charging.

　　A mobile phone, if it is out of battery, is no different from a brick.

　　In order to prevent the phone from running out of power and turning into a brick, iWALK has sorted out related models with large batteries and fast charging. What smartphones with large batteries are there on the market? What fast charging options are available for smartphones?

　　High-power fast charging is the trend

　　Low temperature lithium iron phosphate battery 3.2V 20A -20℃ charging, -40℃ 3C discharge capacity ≥70%

　　The amount of charging power will directly affect the charging speed of the mobile phone. At present, almost only the Apple iPhone is still equipped with a 5W charging head as standard, and most Android phones can basically reach 18W.

　　Among the fast charging powers of flagship phones in 2019, 18W is actually relatively slow. For example, Xiaomi 9 supports 27W fast charging. 27W is not slow, but it is not the fastest charging. Because Huawei P30Pro has 40W flash charging, and iQOO supports up to 44W fast charging.

　　Even vivo suddenly announced news about fast charging up to 120W: vivo preheating information shows that it will announce a new 5G phone at the MWC2019 exhibition in Shanghai on June 26, 2019. One of the highlights of the phone is that it supports 120W super flash Charge. Officials claim that the 4,000 mAh battery can be fully charged in 13 minutes. If vivo's 120W fast charge can be produced, it will definitely be very attractive to consumers.

　　A large battery that fundamentally solves battery life

　　Although fast charging is good, if there is no power connection, you can only stare at it. Wouldn’t it be better if smartphones could be directly equipped with large batteries? Yes, many mobile phones on the market have battery capacities as high as 5000mAh, which can be called small power banks.

　　Low temperature and high energy density 18650 3350mAh-40℃ 0.5C discharge capacity ≥60%

　　The battery capacity of the vivo Z5x mobile phone has reached 5000mAh. The large-capacity battery means that the battery life must be improved a lot; as Samsung's product that deeply explores the thousand-yuan phone market, the Galaxy A40s has a built-in 5000mAh large battery that can also bring long battery life; and Huawei Mate20X This product also has a 5000mAh battery.

　　Not to mention the large 5000mAh battery, none of the batteries in the Apple iPhone next door has a capacity of more than 4000mAh.

　　As mobile phones are used more and more frequently and the requirements for battery life are getting higher and higher, I believe there will be more and more Android phones with 5000mAh capacity.

　　To ensure long battery life, currently there are two main options: large battery and fast charging. There seems to be no better choice. No, you can actually choose to use a power bank for mobile charging!

　　A power bank is like carrying another battery, allowing your smartphone to have longer-lasting power.

　　"The secret to maintaining a good mood is to have a mobile phone with 90% battery capacity." If you want to maintain a good mood at all times, to be honest, carrying a large-capacity power bank with you is a good choice.

　　How to choose a power bank?

　　Safety must be the first priority. Generally speaking, choosing products from well-known manufacturers has guaranteed quality and after-sales service. Secondly, you can choose from richer functions, such as supporting fast charging, supporting its own charging cable, supporting mobile phone holders, etc., and even wireless charging is also very good.
