Read the executive summary: "This article may be unpredictable and dangerous, do not blindly do it"
Hi ~ Hello everyone, in this time when you can't go anywhere, on a bright night, the left hand is coiled with a mobile phone, the right hand has nowhere to put it, suddenly a flash of inspiration, thinking that you have also followed me for five years, and I have been disctented with a seductive luster, and I am trying to figure out how to move your body to continue to fight with me for another five years... How can you extend your use time without losing grace? yes! If you have it, then plug an extra battery into it, ah ~ then plug another speaker into it, ah ~ instantly feel that it is full, almost overflowing
The picture below is the protagonist, ah ~ what a seductive body shape ~ ~
iPhone6sPlus
First of all, I drew a contour diagram with cdr, as shown below, layered engraving, this size is drawn according to the outer frame size of the front panel glass of the mobile phone, so that wonderful things happen, in order to better fit and facilitate future maintenance.
The picture below is the front panel glass bracket, I removed it from the previous broken screen, this phone is specifically broken a few screens can not remember...
Then combine the two of them
The reason for this design is to facilitate disassembly and maintenance in the future
I forgot to take a picture when I carved the middle frame, and only glued it. I have a 1325 advertising woodworking engraving machine because I am advertising...
The following is a modification of the battery, which is dangerous ⚠️
Next to experiment with the battery, turning over the box and finding a battery that was previously purchased in a treasure, a word "big unload eight pieces" at this time encountered a problem, positive and negative pole miscellaneous? Oh, my God... Then Du Niang took a look at how to distinguish the positive and negative poles of the battery, (because there is no multimeter) does not pay off, and finds an answer, that is, to use the speaker to distinguish, the same speaker, connected to the battery, the speaker will be concave or convex, and then I will try one by one with two batteries to ensure that the speaker is a direction!
yes!!! The battery positive and negative pole problem was solved, and then there was a new problem, how to connect the two batteries, tried the soldering iron with soldering... But it ended in failure, and then Du Niang took a look, Du Niang said that in the aluminum is not soldered tin... Oh, my God!!! Because there is alumina after heating there is alumina... Don't die, all to this step, and then rummaged through the box to find a display line, thinking that the clip should be able to connect, as shown below
After this step, I am not sure whether the two batteries are successfully connected in parallel, and I think that the dead horse should be a live horse doctor... Start wrapping the tape as shown below
Plug in the motherboard and try it (at this time I am very scared, afraid of BOOM, when I press the power button...). The screen lit up, the familiar Apple logo (I thought I didn't roll over, thank goodness)
Then used for an afternoon until the battery ran out and the quest started to fill up from 0. During use, I feel that the power loss speed is no different from usual!
At this time, the battery use time forgot to take a screenshot (and follow-up) and then the more you think about it, the more unsafe it is, and it feels that the long connection line will definitely have losses, and it may cause a short circuit, a word "dismantle and dismantle, and then change"
The left hand touches the battery, the right hand has nowhere to put it, so after the time of "three seven two one" thought of a more perfect way, that is, directly put the battery cell contact, through the external force extrusion connection, do not line up, as shown below, the blue strip is to make the contact squeeze tighter, the use of transparent tape winding method ... The only thing missing is that the two cell contacts are not in one position, and the other battery needs to be misaligned to be directly paralleled!
It feels more beautiful in an instant, and the psychological effect is reduced, because there is no longer that long white line. At this time, a new idea burst out ~ and then added a speaker by the way, which was removed from the old mobile phone Meizu MX3, as shown below
Attached to a Meizu MX3 mobile phone that has been with me for several years, it has now been broken, repaired several times, all screen broken, and now the whole has been deformed, there is no repair value, let her bury it in the corner ~ let her voice continue to follow me ~
Run the wrong set, keep up the topic!
I welded the horn directly with wire to the contacts, and did not distinguish between positive and negative poles, as shown below
Because the horn is a bit thick, and there must be a sound cavity, because I tried to take the horn out alone to listen to the sound, the sound is particularly small, put into the original sound cavity after the sound is huge... (Wiped a handful of sweat -_-||.) ）
Because the sound cavity is a little thick, polished, just stuffed in, the overall feeling of the sound is a little bigger, and the bass is a little bit larger, when listening to the song, the whole fuselage is vibrating... Because this speaker and the motherboard and the screen are just squeezed together, when the speaker vibrates, the screen and the back of the mobile phone are also vibrating, and the noise is not.
Then let's take a look at the overall appearance, as shown below

Bottom figure
Four small holes were opened in the top of this place, which facilitated the sound of additional horns
Combined effect
Side after closing
Overall thickness effect
The middle frame was originally transparent, it felt too transparent, a little cheap, and then Rummaged through the cabinet to find the lamp stickers that had been purchased before, pasted it, it felt like two mobile phones stuck together, poofhahahaha However, the overall feel is still good, one-handed holding is not effortless, and even a loss of iPhone4 feel, as for the weight, it feels at least half a pound ... - _ - ||
The next step is to use the battery for a few days, the current maximum 100% battery can be used for 11 hours continuously (or even longer, and my phone has been jailbroken) as shown below
Then strange things follow, such as the use time of the above figure, the battery will be stuck in a certain amount of power has not moved, such as 1% of the electricity can be used for a long time, and does not drop speed, the following figure is the CPU frequency
There is also a strange thing, when charging, occasionally suddenly drop to about 80% and then continue to flush, as shown in the following figure
This problem I did a circle, did not find that do not know why, as if because the battery protection board capacity data is not modified, there may also be the impact of the Coulomb meter, in short, the current endurance time doubled, indeed can be used, the following figure is the battery data detected by Aisi, and each time is different, do not know why, as shown below
Summary: The overall modification of the use of more than ten days, there is no big problem at present, the endurance use time is significantly longer, the overall appearance is not too ugly, the only regret at present is that there is no instrument to modify the true capacity of the battery, resulting in the mobile phone displaying the remaining power is not accurate!
Changing the machine is risky, and change and cherish!
