Each generation of iPhone is almost one of the phones with the largest single unit sales volume, just the iPhone 5s released in 2013, whose cumulative sales have reached 200 million units. Although the performance and sales of the iPhone have soared, the battery improvement in recent years is far less than that in other fields. Today, The original battery of the iPhone is still smaller than the flagship of Android of the same generation. It is still troubled by the problem of freezing shutdown, and even occasionally there is an iPhone battery burning accident.
Despite these problems, according to the normal battery aging law, the mobile phone will have to replace the battery after about two years of use, All these factors together breed an entire ecological chain of iPhone battery replacement. Even if the replacement rate is 5%, the replacement volume of the iPhone 5s alone will be 10 million, and the volume of this market is far larger than expected. In addition, at the end of 2015, the large-scale iPhone freeze shutdown and the iPhone memory upgrade that many iPhone users are still talking about have become phenomenal events, paving the way for the popularization of iPhone battery replacement in disguised form, and even many small white users have plans to replace the iPhone battery.
Take the iPhone 5s as an example. The prices of its batteries in Tmall and JD are between 60-90 yuan and 100-130 yuan, respectively. However, most of them are inferior brands, and big manufacturers are rarely involved in this field. Perhaps it is the current market situation that we are looking for. Romans, originally in the field of mobile power supply and accessories, has also launched its own set of iPhone battery products. his The selling points are larger capacity than the original battery, safer gel cell and better low-temperature protection.
However, the price of the 5s/5c and iPhone 6 batteries of Lux is 79 yuan and 89 yuan respectively, which is more conscientious than some other brands. In addition, the promotion points of this series also include DIY experience. Along with the battery, it also includes complete tools and accessories for disassembling the iPhone, so that even ordinary users can replace the battery of their favorite phones themselves.
Packaging and appearance
Romance iPhone battery includes four models from iPhone 5s/5c to iPhone 6/6 Plus, corresponding to 1700mAh, 1810mAh and 2915mAh respectively. The three versions are packed in a unified hard paper box, with detailed descriptions of accessories and battery parameters on the back of the package. Interestingly, the iPhone 5s/5c battery, whose capacity is 10% larger than the original one, has a longer corresponding mobile phone pattern than the other two versions, and also conveniently blackens the battery capacity of the iPhone 5s
The battery body lies on the first layer of the drawer type package, and the corresponding positions are provided with grooves for taking out the battery conveniently. The second layer is very rich in accessories, including instructions, suction cups, double head screwdrivers, tweezers, rocker plates, paddles and double-sided 3M adhesive for fixing batteries.
The manual has a very detailed process and description of the disassembly of the real machine. The front and back of the manual are the disassembly process of the iPhone 5s/5c and iPhone 6/6 Plus respectively, which saves the user the trouble of checking the online tutorial, and the real machine diagram can easily confirm many action and location details.
I think many of you are familiar with the other parts. Double head One end of the screwdriver is a 1.2mm cross screw, and the other end is a 0.8mm pentagonal Torx screw used to turn on the external screws of the machine body. The suction cup is used to suck up the screen, and the warping piece is used to embed the suction gap. The warping rod and tweezers are used to deal with the precision components inside the machine body.
In fact, there are also similar products in the market that provide these disassembly accessories, but it is estimated that this set of Romos is the first set of products with its own tools. After all, there are circuits inside the mobile phone. The common metal material is too hard and conductive, which will increase the chance of damage to the machine. Therefore, all accessories, including the screwdriver handle, are made of uniform frosted white plastic, with good texture and workmanship.
The battery has a handy handle sticker, which is no different from the original iPhone battery except for the text logo. There are product and usage warnings on the back of the battery. It can be seen intuitively that the battery thickness of 5s/5c and 6/6 Plus is almost the same. The battery area is proportional to the capacity. The battery of 6 Plus is several times larger than that of 5s/5c.
Enlarged view of independent electricity meter chip
The iPhone uses an independent electricity meter chip, which is used to feed back battery related information to the system and control numerous circuit outputs. The iPhone freezes and shuts down in winter, the power is not even, and the power indicator has obvious problems, all of which are directly related to this chip. Apart from the lithium battery itself, this circuit board is crucial to battery performance, so some phone users still have the habit of looking at the power meter chip after buying the iPhone battery. Interested users can tear off the protective sticker to see the inside, and we will tear it down first.
Among them, the Romance iPhone 6 Plus battery uses the electricity meter chip used by Apple's original battery. The specific model is the SN27545 customized by Texas Instruments for Apple. The circuit board is also black as the original. In the field of lithium batteries, Texas Instruments has the habit of selling cells with electricity meters. Although the cost is high, the quality of batteries and the accuracy of electricity meters will be more guaranteed.
Battery replacement
For ordinary users, dismantling is a very tall job, which sounds far away from the public. But in fact, the iPhone itself is a product with extremely optimized production and supply chain. The disassembly method is so simple that it is "heinous". What we have in front of us is more a psychological threshold. The whole disassembly process can be simply summarized as: screw, open the cover of the suction cup, remove the cable, pull out the battery, reset "6 steps. As long as you follow the tutorial seriously, it is difficult to figure out problems
Here we take the iPhone 6 Plus as an example. This test machine is the first batch of machines in 2014. After many endurance tests and daily operation, the battery has been aging to a certain extent.
The first step is to turn off the machine and tighten the screws, The iPhone has used the bottom fixing screw+top snap structure for many years. In order to be waterproof, iPhone models after 6s also added a ring of waterproof glue between the screen and the body. During disassembly, the hot air blower/air duct was required. However, the previous machine was a relatively simple snap structure. In this step, just unscrew the Torx screw at the bottom.
Place the suction cup above the home key, and lift it with a little force. It does not need to pull out a large gap, as long as the warping piece can be inserted. As long as it is not too violent or too fast, there is no need to worry about bending the screen.
Slide up the home key to both sides, and you can hear the sound of internal snaps being opened one by one. The screen can be lifted after a circle around the fuselage. It is worth noting that, The iPhone 5s has a flat cable connection at the home key. Lift the screen Don't use too much force when doing this. You should first pull out the cable.
Flat cable protection cover fixed by 5 cross screws
4 stacked cables
After unscrewing 5 screws (1 long and 4 short), you will find that there are 4 flat wires in it, including Cable arrangement for multiple modules such as screen, touch and Touch ID. However, they have a clear relationship between the upper and lower levels. You can pick them up one by one with a stick, and you don't even need to remember the order.
We move our eyes below the SIM card slot (the one with many holes, because the previous iPhone has no dust-proof design, this position will accumulate more dust after a long time of use). The "two grids" below are the protective plate of the battery connector. Unscrew the screws on the horizontal metal cover plate (one long and one short), You can see the battery cable below. Take it easy, and the machine will be powered off.
Then the whole dismantling process was the most enjoyable, and it was also the part of "key and difficult points". There are three "stickers" under the iPhone battery, which are disposable plastic pulling handles.
Use tweezers to roll up a part of the adhesive and slowly pull it out horizontally. Pay attention to the angle at which the adhesive strip is pulled out. If there is no problem, the entire strip can be pulled out as smoothly as the factory protective film. However, if the adhesive strip is accidentally broken inside, a hair dryer will be used. An ordinary household hair dryer will blow at the corresponding position of the battery on the back of the fuselage for tens of seconds to soften the adhesive, and use a stick to "semi violently" tilt out the battery.

The flat cable connectors of the two batteries are the same, but the flat cable shape is slightly different
After the battery and the body can be separated without trace, the complimentary adhesive can be placed and the new battery can be connected. Here is a warm reminder. Before putting the adhesive, put the battery into the test position and fold the flat cable. The author remembered not to fold the flat cable until he glued the battery with his hands... Then he reversed the process just before, reset the flat cable and the 2+5 screws in turn, cover the screen and screw the outermost two screws, and light up the machine. At this time, I will say to myself in silence, Niubi.
Before and after the battery replacement, we conducted a one hour game test. After two years of use, some aging batteries lost 41% of their power after one hour of large-scale games (wild drag racing 8), which is significantly different from the 28% of the power loss of the battery life test just bought that year. After the battery was replaced, the endurance performance returned to 28%. The battery capacity seems to have no false label. Of course, The capacity density of the iPhone battery itself has no threshold
It is worth noting here that the new battery density may be higher. In the two old iPhone 5s/5c models, their replacement battery capacity has increased from 1560mAh to 1700mAh, with an increase of about 10%. This must be a good relief for users of these two models.
Summary
The actual difficulty of disassembling the machine will be much smaller than many people expected, and the whole process will take no more than half an hour even if it is operated against the instructions. Of course, the whole process is more enjoyable for the airplane users to enjoy the process of disassembly and the sense of achievement. In this field, Opponents who start at 79 yuan and have a full set of tools and accessories are all brands that have never stopped writing. The iPhone battery of Lux is priced in this range, which is already a bully.
From the perspective of computer users, this set of batteries is a good alternative, and can even be used as a gift for "Bear Boy". Of course, it is also a good choice to change the battery in front of your girlfriend (squint).
