@@Myriddlemind Okay, here's another update. I checked the battery stats this morning and noticed that shortly after 12 am the battery took a nosedive from 95% to 10%. This wasn't a gradual decrease, but a sudden drop. The screen was locked and no apps were open. I bought this device to refurb and sell in my shop and was hoping I could preserve the battery health functionality with the tag on flex. Now I'm afraid it's a little too unstable for that purpose.
If you remove the Tag On, could you please verify what reading you get with 3U Tools? When we have tried this, 3U Tools reads old battery value is the Tag On is nog connected to the iPhone.
**Troubleshooting** If the old battery health still appears and the battery notification persists, you will need to re-trigger the iOS stack battery notification window. To do so, remove the new Ampsentrix battery (with its tag on flex) and install any new test battery with a functional BMS. This will prompt iOS to recognize a battery with a new serial and allow you to restart and repeat steps in the video.
If you wanted to program the battery using the tag on flex, would it work the same? In other words, does the included tag on flex work the same as the previous Qianli tag-on flex models?
Great tutorial, but I would make removing the tag on flex mandatory and not optional. The tag on flex can potentially move and rub the battery enough to short out causing it to need to be replaced.
you need to leave it inside otherwise it will show old condition in 3U Tools and will work the same.. Also try to fully bend to the back the battery fpc.
Funciona con todos los modelos? Puede haber alguna actualización que revierta los porcentajes de la vida de la batería como sucedió recientemente? Gracias
Con la Jcid queda 100% aunque actualices. Y usas solo un tag on para todos los equipos. Con este sistema nuevo tenes que dejar el tag on si no queres que el cliente venga al mes que viene al actualizar su equipo.
How are you able to do this without a second battery? I thought you need the second battery to bring up the "non genuine" message and then use the battery with original BMS and tag on flex. When I try the method in this video I don't get the battery message and the battery health still shows the old number. Please advise.
@@faridjxo4884 I think you have to have a second battery to get the “non genuine” message. Then switch to the new battery with the original BMS and tag on flex.
Is battery adhesive included in the kit like all the other ampsentrix and service pack batteries or sold separately for this model? Didn’t see it in the video.
@@peterluong5812 yes actually, im pretty sure I had a bad tag on flex, once you prompt boot by cable you need to power off, then power back on manually (with power button)
I did this repair just now on a iPhone 13 mini using the tag on flex. Booted the phone with the lightning cable like you showed. It still shows the old battery health from the customers previous battery.
Its possible that the tag-on flex was in the wrong orientation, or had some unwanted tension on it. It needs as much room as it can have inside the phone like any tag-on flex. Try it again and see what happens
@@MobileSentrix what are those reasons? I would rather buy the AmpSentrix Core batteries w/o tag-on flex & save $1 on every battery + be able to center the battery properly instead of scootch it too far to the left, to accommodate the extra thickness of the additional flex material. If there are actual reasons to leave it in, I'll happily do that :-) I just want to know and understand what those reasons are.
as connections with power can get hot, solder is not very reliable. especially if someone uses low melt by accident. battery spot welders are cheap. under $50-75 I think
What do you mean by “prompt to boot with lightning cable”? Do you mean just plug in cable to boot it or do you have to something first? Prompt word is throwing me off. Helps pls
WHY??? I have been replacing batteries for 14 years and it is rare when a customer is really upset that it is not an original battery. 90% of the time, they don't really care. If they do, as an IRP, I just order an original and program it with Apple software. Even in Apple internal docs, if they open a phone and see a non-OEM battery, they require you discharge the phone and then proceed with any repair other the battery.
I think this is kind of important especially when reselling and multiple parts have been replaced on the device. Its a little bit of an extra step but Ive noticed a lot of customer asking about the battery health lately. For repair service if someone is paying to have their battery replaced this doesn’t matter that much unless the customer is willing to pay more
Here in USA people really don't care about the warning messages of battery or screen. In Colombia people are obsessed with those messages , battery percentage or true tone. Me personally I don't care
Love your vids but please equalize audio levels of voice and music. Music gets too loud compared with your voice. I am constantly having to turn audio up and down because of this and its very annoying. Thanks.
I think the best solution is to stop buying iPhones, I’m a iPhone fan, but I’m sick off Apple locking down everything, wait and see when the new iphone 15 is out, you only can charge it with only approved apple USB C cable, time for people like me to cop on, and stop giving apple my money
I DEFINITELY agree that Apple is going WAY to far in their BS by serializing EVERYTHING. I joked around with my wife saying that “Watch. Next thing you know they will find a way to serialize the back glass.” Sure enough, with the new 16’s that came out, they did. WTF!!!!!!
Is the process same for higher capacity batteries? I wonder what that would show for battery capacity and health if it’s higher than original spec? Love the vids, keep ‘‘em coming ❤
@@MobileSentrix I asked a technician and he told me that there is a risk of it burning if I put more amps on the iPhone, could this be true? I have an iPhone 7
@@henryce7 hi there , im a iphone 7 user too . to answer your question it is about the quality of the battery . some company sell conterfeit product out there so you need to be careful. I use high capacity battery and it works just fine although it produce more heat but it is logic but you need to make sure you buy the trusted company for the high capacity battery . some of them are knock off product but claim to be high capacity. mine luckily is good at 2400 mah for iphone 7 . some knock off battery claims 4000 mah for iphone 7 which is totally bs ofc. so i hope i answer your question.
Yes, It works when you leave the tag on Flex but sometime it won't work properly, I have done 13 pro max in the last few weeks, and the customer returns it back.
@@kcastillo1234 because leaving it in is useless and costs money. it also has additional potential for errors and you can continue to use the day on in the workshop. So all of that is worth a few seconds to me
I definitely wouldn’t leave a mobile sentrix circuit board in my phone if it isn’t needed. Good chance that flex will fail and then you’ll have to open the phone up and take it out anyways.

If you wanted to program the battery using the tag on flex, would it work the same? In other words, does the included tag on flex work the same as the previous Qianli tag-on flex models?

Could someone please help tell me what that rotary tool that he is using is called? Can I get it on amazon?

leave them in the phone as there are several reasons to do this. You get one with each battery as well. so there's no need to hold on to them.
@@MobileSentrix what are those reasons? I would rather buy the AmpSentrix Core batteries w/o tag-on flex & save $1 on every battery + be able to center the battery properly instead of scootch it too far to the left, to accommodate the extra thickness of the additional flex material.

Stays the same
can i just solder it using a solder iron ?
as connections with power can get hot, solder is not very reliable. especially if someone uses low melt by accident. battery spot welders are cheap. under $50-75 I think
yes, but you need a different soldering wire, different alloy otherwise regular soldering wire will not stick to the battery.
These can now be bought for like 4€ on aliexpress depending on phone model
Still working today this method?
I assume soldering is out the question ❓
Can you just solder it instead of the tack weld? If no, why not?
no, don't solder batteries.
Is the tag on flex reusable?
What do you mean by “prompt to boot with lightning cable”? Do you mean just plug in cable to boot it or do you have to something first? Prompt word is throwing me off. Helps pls
Yes Prompt to boot just means turn it on with the cable and not the power button.
Is this working in 16.5 ?

To get the battery health on phone
