Yes, this is what I also did. I replaced my battery without chip, then backup iPhone through iCloud and 3utools. In few days I need to downgrade iOs and then update again to 18.1
Except install after market battery and flash wich 3u tool, you also need to transfer the original battery cable to the new battery. You can refer to this video. th-cam.com/video/BC5kjx4-920/w-d-xo.htmlsi=EtDOcp8bVnsPv6gW However, the specific transfer method differs depending on the type of battery.
So you do need the original BMS and new tag on flex ? I have xs max with 17.4 and it keeps showing original health. I will try the 3u tools options next
I had my iphone 12 mini battery replaced. At the time it was on ios 17.5 and battery remained the same as before. To fix battery health should i install 17.4 ios version and then do this recalibration or while installing 17.4 it will be fixed as well ? Its important so please answer.
Can I remove the tag on flex after flashing? So when I insert the battery with original bms after flashing without tag on flex, 100% is still displayed. My question is whether the old battery capacity is displayed after an iOS update
I have tried to flash iOS 18 and check "fix battery health" but 3utools give error and flash is not complete. 3utools error says: "unable to exit restore mode". If I try to fix battery health with iOS 17.7 the error doesn't happen. Is iOS18 even harder to restore 100% battery health? Any solutions?
In fact, before installing the new battery, we need to transfer the battery cable from the original iPhone battery to the new battery. Therefore, you can understand that the programmer is the original cable.
What happend if the replacement lf the battery, iphone 12, is made with an ios versión lower than 17.4? I mean if the bms is tranfered to the new battery and health+ cycles reprogramed vía tag flex, would it stil show baterry health after upgrading to ios 17.4? Or this issue only affects if you try to replace the battery on ios 17.4 or later?
Does this whole process still work on ios 18.1? My battery already replaced with new battery but has still same 81% batt health. It never becomes 100%. Can I still Back up my iPhone using 3utools>Anti recovery flash>restore Data from 3utools? Can I get my iPhone back to same data with 100%?

That’s because the BMS is serialized, and if you use a different BMS than the one that was originally in the phone, it’s gonna show the unknown battery message
It depends on the type of battery you use. Regular aftermarket batteries typically require tag on flex, while the latest introduction of popup-free batteries eliminates the need for it. For specific details, I recommend checking the description of the video, my friend!😜
After a regular battery replacement, the battery health will gradually improve. If it only improves slightly, it's important to consider whether the replacement battery is brand new or refurbished. Is the battery made of pure cobalt or ternary materials? What type of protection board is used? Is the original Apple protection board reused? If the original protection board is used and the battery has undergone numerous cycles, it may require a refresh.
When you backup, is the data stored in the laptop or cloud?? And does it demands an internet connection to backup??
I am at ios 18.01, do I need to downgrade to 17.4 to get it to work and then update to ios 18 ?

will this work as well with ios 17.5.1?

You don't need to click on fix battery health for the ios18. Just click flash and it will do it automatically

Is it a one-off action or does it need to be done for every firmware upgrade?
it's one action. i downgrade from 18.0 to 17.7 after battery health fixed, i upgraded again to 18.0 through my phone.. battery health did not go back
So.. we don’t need any programmer to modify battery health (just swap the bms and flash with fix battery health) ???
Not possible
In fact, before installing the new battery, we need to transfer the battery cable from the original iPhone battery to the new battery. Therefore, you can understand that the programmer is the original cable.
@@DBXTUBE so what is the new battery we need to buy ?
pretty much

You are in luck then, you can continue using it without genuine battery message or loosing battery health.
