Redmi K40 is a mid-range mobile phone owned by Xiaomi, officially released on February 25, 2021, equipped with a Qualcomm Snapdragon 870 processor, supports 5G network, has a 120Hz AMOLED screen, a 48-million-pixel rear triple camera, a 4520mAh battery, and a 33W fast charging function. This phone received a lot of attention and popularity from consumers when it was released, because it is very cost-effective, and the price starts at only 1999 yuan.
I bought this phone in May 2021, and at that time I felt that it was the best phone I have ever used, whether it is playing games, watching**, taking photos, or daily use, it is very smooth and comfortable. However, time is the most cruel, and with the use of the phone, the life of the battery is gradually decreasing. By the end of 2023, I found that the battery life of my Redmi K40 is not as good as before, and to meet the normal use of the day, it must be charged three times, and sometimes it will automatically shut down when the battery drops to 20%.I began to think about whether it was time to get a new phone, after all, there are already a lot of new phones on the market, such as Redmi K60, Xiaomi Mi 14, Huawei P60, etc., all of which have better performance, stronger photography, larger battery, and faster charging.
However, when I actually picked up my phone and wanted to place an order,I hesitated. I think of the little bits and pieces of me and the Redmi K40, which has accompanied me for three years and witnessed many important moments in my life, such as graduation, work, etc. It is also a good companion for me to entertain and study, I have used it to watch countless movies, listen to countless songs, learn countless knowledge, and play countless games. I suddenly felt that I was not ready to give it up, I still wanted to continue to use it, it was no longer just a mobile phone for me, but a memory, an emotion, a trust.
So, I decided to give it a new battery and give it a new lease of life. I searched on the Internet and found that there are many stores that sell Redmi K40 batteries, ** and it is not expensive, about 60 yuan. I picked a store with a good review, placed an order, and received the goods on the third day. I opened the package and saw a brand new Redmi K40 battery with a set of tools for changing the battery, as well as an instruction manual telling me how to remove and install the battery.
I followed the steps in the manual, carefully opened the back cover of the phone, removed the old battery, installed a new battery, and then reattached the back cover, charged the phone, and turned it on. I saw the familiar boot screen and heard the familiar boot**, and it felt like I had met a friend who had been reunited for a long time. I opened the settings, looked at the battery information, and found that its battery information had been restored to excellent. I tried the other features of the phone and found that there were no problems, and it still worked as well as before.
After changing the battery, I was thinking, with the passage of time, the technology of the mobile phone is also improving, in 2024, can the Redmi K40 still meet the needs and expectations of users?
From the hardware side, the configuration of the Redmi K40 is not very high-end in 2024, but it is not too far behind. Although the Qualcomm Snapdragon 870 processor is not the latest flagship chip, it can still cope with most daily use and gaming scenarios in terms of performance, and there will be no lag or lag. Moreover, I really think that the performance of Redmi K40 is already very good, for daily use, such as swiping Weibo, watching**, playing games, playing**, sending messages, taking pictures, etc., there are no problems, running smoothly, no lag, no heating, no power consumption. I'm not a user who pursues the extreme, I don't need every new phone to experience it, I just need to be able to use it normally. I think the Redmi K40 is already able to meet 90% of my needs, and the remaining 10% of my needs can be supplemented with other devices, such as tablets, computers, cameras, etc.
The Redmi K40's 120Hz Samsung E4 screen is also a highlight in 2024 and is not far behind. Although the 48 million pixel rear triple camera is not the highest number of pixels, it is not bad in terms of photo effect, and it can shoot clear and vivid** to meet the general needs of photography. After replacing it with a new battery, the battery life of the Redmi K40 has also been improved, which can support normal use for a day, and there is also a 33W fast charging function, which can fully charge the battery in a short time without worrying about the problem of insufficient power.
In short, what is the experience of changing to a new battery and still using the Redmi K40 in 2024? My answer is, it's a pretty good experienceAlthough the Redmi K40 is no longer the latest mobile phone, its hardware and software can still meet most of the user's needs and expectations, and will not make users feel too backward or uncomfortable. Of course, if users have higher requirements for their mobile phones, or want to experience more new technologies and new features, then it is also a good choice to switch to a higher-end mobile phone.
