A few days ago, the European Union introduced a new law "New Battery Law".
The bill stipulates that from 2027, batteries in any household appliances and electronic products sold in EU countries should be designed with portable batteries, and consumers should easily open their mobile phones or electronic products to remove or replace the batteries themselves.
This bill is another big move on digital products in the European Union after killing Apple's charging interface.
The bill was immediately passed by an overwhelming majority of 587 votes in favour, 9 against and 20 abstentions.
In fact, this year there are also a number of removable battery mobile phone release, but there is no domestic market, such as Samsung's XCover 6 Pro, can be bought in the second-hand market, this mobile phone has all the functions of the mobile phone ten years ago, such as 3.5mm headphones, LCD screen, three-proof design, support SD card expansion, etc. It's just that the processor uses 778G, and the charging speed is only 15W, which is a bit crotch-pulling.
There is also Nokia's C12 Pro, which is sold in China, but the post-release reviews are all overturned. The appearance of the ugly water drop screen, large chin, large black edge, LCD screen, in the evaluation, the back cover is very intolerant to scratches, a little friction is not able to eliminate scratches. The processor uses Unigroup's 28nm 9863A1 chip, which runs the Android 12 system in 2023, with a maximum memory configuration of 3+64, but does not support memory expansion. There is only one rear camera, 8 million pixels, scanning the code is difficult, the front is 5 million. And only support 5W charging, but promote "all-day battery life", think about it, all this configuration, can only look at the web page to call and text, what games can you play.
The advantage is that the battery is removable 3000 mAh (4000 mAh for the Pro version), and the screen can still smash walnuts.
Now want to buy removable battery mobile phones, can only choose some professional rugged mobile phone manufacturers of products, although the performance is not very outstanding, but people have made the battery to the extreme, and even 20,000 mAh battery mobile phones. And detachable.
Replaceable battery mobile phones have been commonplace ten years ago, since Apple launched the first non-replaceable battery mobile phone, major mobile phone manufacturers have followed suit, have adopted this mobile phone design scheme, their flagship mobile phones are designed into non-replaceable battery products.
There are pros and cons to everything, and so do removable batteries.
Apple's choice of this design scheme was also considered in many aspects.
Merit:
- The battery that cannot be disassembled can be designed into an irregular shape, thereby improving the utilization rate of mobile phone space, making the mobile phone design thinner, the internal structure tighter, and the gap narrowed, thereby reducing the looseness of internal parts and improving the service life of the mobile phone to a certain extent.
- The battery can not be removed, which further improves the stability and safety of the mobile phone system, because the battery cannot be easily removed, the system to find the mobile phone and satellite positioning has the remaining power transmission, locate the location of the mobile phone, thereby reducing the theft and loss rate of the mobile phone.
- Environmental protection is also an advantage over removable batteries, non-removable batteries reduce the production of battery shells, thereby reducing resource consumption; And compared with removable batteries, recycling is more standardized, and can also be standardized for reuse, and many of the batteries that were not removable before have been littered, causing environmental pollution.
- To a certain extent, the functionality of the mobile phone is increased, such as the waterproof function, and the non-removable battery is relatively easy to achieve.
- Removable batteries increase the security risks of mobile phone users, because some users are cheap in the case of true and false, and it is easy to buy inferior removable batteries, which also have a certain impact on the performance and life of mobile phones. Non-removable batteries largely avoid this.
Shortcoming:
- As mentioned earlier, everything has pros and cons, and so do batteries. The battery that cannot be removed has brought people an inconvenient experience to a certain extent, such as not having a charger, can not immediately replace a fully charged battery, so that the mobile phone is full of blood and revived.
- The non-removable battery has caused people to bring more bulky and huge charging treasures when they travel.
- Any battery has a problem of life, although the non-removable battery life is relatively longer, but it also has a life, at most one year, the life of the battery will be weakened, people need to replace the battery must find a professional mobile phone repair personnel to replace.
- Although the non-removable battery is environmentally friendly, but only the battery is environmentally friendly, the battery mobile phone life to the end, people will put this kind of mobile phone idle, over time will be thrown away, originally replaced battery can also fight for another year of mobile phones, premature throw away caused a certain waste of resources. It is estimated that this point is most valued among manufacturers designing non-removable batteries.
Some mobile phone repair practitioners said that many of the batteries that were removed and replaced and the mobile phone batteries from more than ten years ago have not changed in appearance and internal structure, but the interface has increased the cable from the previous metal contacts. For example, the current Meizu, Xiaomi, Huawei mobile phone batteries, are all regular rectangles, Apple is relatively different, the rectangle is a little long.
There are many mobile phone back covers that can be easily removed, but to remove the battery, you need to remove the motherboard bezel and the beaffle of the tail parts, which increases the difficulty of removing the battery.
So in low-end mobile phones, the non-removable battery does not have much advantage in design, does not make the phone thin, and does not waterproof.
So can we think of a way to improve the security of mobile phones, and also easily replace the battery to improve convenience?
That's the dual-battery solution.
A mobile phone is equipped with two batteries, one 500 mAh and one about 4000 large-capacity batteries.
The small one can be designed as an irregularly shaped non-removable battery, so that the phone can also maintain a certain data stability after it is turned off.
The large battery can be easily removed and replaced. And the power supply of the mobile phone first chooses to use the power of the large battery, and keep the small battery always in a state of power.
This not only ensures the security of the power supply of the mobile phone, but also facilitates the user's experience.
For waterproof, now in addition to a few flagship mobile phones, most of the people's mobile phones are actually not waterproof, as long as the quality of the back cover is done, I believe that the current technology can achieve the airtightness and closure of the mobile phone.
In fact, to put it bluntly, the dual-cell design of many mobile phones is actually a design of two batteries connected in series or parallel, and can take off when charging.
Do you say this is feasible? What are the advantages and disadvantages?
