Thanks man. I don't know why I've been so hesitant to get into this. Maybe cuz customers were just paying for the battery replacements and could care less about the battery health management indicator. But I think I'm going to start switching over to this method. I think it's a better quality repair
me for bms spot welding only 50% successful the bms board is very fragile and very weak also the battery connector is very easily torn off anyway very great video your grinding bms board is so impressed best video thank you
That feeling 😅 when you know step by step on how to do this and still wanna Watch because you’ll definitely get a useful tips that you don’t know about 😊😊😊
So we can remove the tag on flex cable once the iphone has boot up with ? I mean, the second time iphone boots after the process, we can remove the ToF cable ? thanks
@@VCCBoardRepairs I’ve just done a bit more research and to help anyone looking for the same answers I was: - this works with any new battery, as long as you have the original bms - it works with all tag on flex brands and they’re safe to remove after the initial calibration.
@@AureaBulgariayea but when taking out the tag 3utools will still show the original battery capacity read from the bms, despite the fact that the phone will now display 100% and also, after dealing with few devices i have replaced the battery in with this approach, i noticed some significant drop in the phone's battery capacity percentage after some 2-3 months of time, which leads me to believe that it would be better to leave the tag inside. but for now i can't be 100% sure about that
I have been getting mixed results. I use Xcap batteries with Xcap pre-programmed tag flex, also JD ID tag flex with programmer. Around 1 in 4 repairs are unsuccessful. When booting the phone for the first time with the power cable inserted and tag flex attached the phone shows '0' percent and does not charge. The cable is attached to a good power adaptor. I follow the same process for each repair. I just don't understand why some work and some fail. Any ideas?
i do bms swap on xs max several months ago, it doesn't work. i dont have a programmer and the battery indicator is 1%. did i mess the bms or only needs programming?
Is it really necessary to buy the pre-programmed Tag On Flex, or are all tag on is pre-progrramed? Can I just order any tag in flex on Shopee? New subscriber here
Not all solutions are the same. So if you're going to follow my video, use the Xcap battery & tag ons. If you're going to use other brands, you're on your own. They may or may not work the same.
Hi VCC. So I've done as per your video. I boot using the cable and I don't get battery message, and the phone reads the original battery health. Any ideas?
Nice video :) However doesn't the battery life reset to the previous health after actualization or restore of the device when you disconnect the tag? Do you have experience with that? Also the phone was not charging because your charger is not MFI therefore after turning on phone you have to reconnect cable :)
it won't restore to previous maximum capacity after restoring the phone but it definitely will if you connect any other battery or power supply (which of course leads to the "important battery message") then back to this "original" battery. also i noticed that not leaving the tag-on flex inside the phone after the repair probably leads to faster capacity degradation from the programmed 100% to the original percentage. but for now i'm not 100% sure on that, plus there's a chance this percentage drop will never quite hit the original percentage and just stabilizes itself on the actual level after a longer period of time because the battery's capacity is periodically measured and calibrated over time. so i noticed this fast drop on some devices after approximately 2 months from battery replacement but i can't tell how the situation will look after next 2 months or a year p.s. also the 3utools keeps showing battery's original data even if your iphone displays the 100% capacity
@@BillAnon If you want to use the solution I show in this video, then you have to follow it exactly like in the video. If you want to experiment doing your own method, you're on your own for that one
@@VCCBoardRepairs Well, you mentioned in the beginning that even a genuine Apple battery would give the same warning. It seems to me the Apple battery would already have the BCM so all I would need is the tag-on flex cable. Worse case, I grab the BCM from the original battery. Thank you so much for the ideas.
you did a very clean job! congratulations! two questions (i use qianli tag flex): 1. is this flex reusable or you need to buy new flex for every battery you change? 2. did you try to update the phone or factory reset it to see if it keeps the battery health percentage? i currently leave the flex in the phone everytime i do this job and it is very difficult to do this neatly in such a tight space. sometimes it breaks my fpc connector and needs to resolder a new one to the tag flex. thank you.
1. I reuse the tag on flex. I don't leave it in. 2. I personally haven't restored it. But I know the injured gadgets team has fully tested it without the tag on flex and they confirmed it is still working fine. I did do an update to the phone after the BMS swap and it's still working fine.
@@VCCBoardRepairs if you dont leave it there yes it will work but if you put in 3utools it shows the old percentage and charge cycles if you leave it there in 3utoold works like a charm better leave it inside and the tag on flex leave it between the flex of battery from my experience and i have changed a lot of them from xs-13 pro max tag on flex need from 11 and above
@@VCCBoardRepairs i am changing batteries for iphone every day the percentage in phone keeps 100% but if you see in 3utools its the old one i didnt use xcap this specific tag on flex sorry if i make mistake but can you see in 3utools if the percentage is ok?
According to the Xcap (Injured Gadgets) team It takes up to 14 days for 3UTools to reflect calibrated data. The device displays accurate data after calibration.
Great Video.! I have used this method to replace my iphone 12 Pro Max battery that was less than 80% (73%) and so was showing the service message 'your battery health is significantly degraded'. I replaced the battery and set the health to 100% and cycle count to zero. Even though the health is now showing as 100%, the service message is still there? Do you know why this may be? and how do I remove it? Thanks
Do you need your battery replaced and don't want to lose the battery health, contact me for a quote: www.vccboardrepairs.com/contact-us
Top technician wish I had half your skills keep up the good work fella 👍
Wow, thank you
Works with other batteries too. Mine worked with battery from another iphone 11. You are a legend
Interesting! Good to know!

Definitely give it a try. Or at least, give the customer the option
@@VCCBoardRepairs absolutely with you giving videos like this I kind of can't help but give it a shot. Seriously appreciate your content.
Great video clean and precise
I appreciate that!
Thanks for the tutorial - and making those preprogrammed tag on cables available...just purchased one. Liked and Sub'd!
Thanks for the sub!
Hey Jesse, thanks so much, can the tag on flex be used more than ones?
Secondly can a tutorial come in for Truetone transfer with the a108 programmer
Love your videos Jesse. See you on the group.
Awesome! Thank you!

Clean Job 💗
Thank you!
DOes this message appear only once when you start the phone or does it pop upp all the time?
can I change the battery health and cycle before changing cell so that I can activate the battery health first then change battery cell?
great content👍
Thank you 🙌

That's strange. I haven't had any issues with all the batteries I've done. Maybe the spot welds are not good? Or maybe the BMS board gets damaged?
@@VCCBoardRepairsMy spot welds are secure and I am extra careful not to damage the BMS board. I always fully reset and install latest iOS.
Is it possible to use a programmer instead of the small part that connects to the battery??
Nope.
Can we use the tag on flex again or is only for one time programming
You can use it multiple times
i do bms swap on xs max several months ago, it doesn't work. i dont have a programmer and the battery indicator is 1%. did i mess the bms or only needs programming?
If it's not Xcap BMS solution, then i don't know.

use icopy plus?it easy
Try to Quick Flash on 3u tools & select "fix battery health" in the pop up
is the cycle count reset to zero using this method?
Yes, but it's automatic
wait.... i already use this method but u need 1device to reset the battery health but u not show in this video u reset the battry health correct?
Are you using Xcap battery and tag on flex?
he don't use icopy plus?
No he doesn't

Why not just weld it together without filing it 🤔.
as i say in the video, is to get a better weld
