iPhone X: How to reset Maximum Capacity with New Battery

Tue, 08 Jul 2025 10:11:25 -0700

Update:
I've now chosen to recommend my customers to replace the entire battery and just deal with the non genuine battery warning. That way we are not reusing used battery parts and everything feels much more professional.

Original Post:
Hey there,

I replaced a battery on a customer's iPhone X with a ampsentrix battery. Also used my icopy2 programmer to program the new battery.

I got him to try performing a full drain and charge to calibrate it with no luck. He even did it twice.

How can the "maximum capacity" be reset?

Thanks

Kevin

iPhone X: iPhone X cannot get past lock screen after repair

Wed, 25 Sep 2024 09:55:13 -0700

After replacing a broken iPhone X screen I try to enter the passcode on the phone and after pressing the final digit the phone freezes and doesn’t proceed, cannot be locked and can only be hard reset. Can still receive and take phone calls but can’t get past the lock screen. Problem persists after old screen reinstalled. Any ideas?

Cheers

iPhone X: Powered up after opening case!

Thu, 20 Jun 2024 17:15:00 -0700

Hi,

I removed my SIM card and powered down my iPhone X prior to opening the case to do a screen change, almost immediately the phone lit up? try as I might holding one side of the case with one hand while trying to power off with my other hand it just wasn’t possible, so I immediately removed the battery connector. Before I go ahead with the screen change I was hoping that you can reassure me that nothing would have happened to the software or other parts, the phone was only with power for approximately 45 seconds.

Thanks

iPhone X: Face iD Not working due to proximity sensor failure.

Wed, 13 Sep 2023 17:19:51 -0700

I have a iPhone X on which I performed a screen repair, Iam a regular worker and know my stuff. I performed all the steps which are necessary to retain the face id and I succeeded too but only temporarily. After a month or two my face id stopped working, my phone's proximity sensor doesn't works due to which true tone has also vanished. Portrait mode does not works either. Can anyone help me out on how to restore proximity sensor? I know for sure if i get it up and running again then face id will work like a charm. Any suggestions, ideas, help will be appreciated.Thanks

iPhone X: New LCD screen showing Burn-in from Old OLED display

Fri, 21 Jul 2023 10:03:38 -0700

I just replaced the Burnt-in OLED screen on this iPhone X with a brand new LCD display. All seemed fine until today, I pick the phone up and it's showing the same Burn-in pattern from before. Did I receive a used display under the guise of new or is something deeper the issue? This LCD was obtained from iFixit

I screwed up today.

customer came in with a broken display and I replaced it with a new one. I accidentally overwrote his original display information with the replacement display. I have no true tone now. Is there a fix for this? I have JC PRO1000S for writing display data.

This is the report from JC repair. The data should exist on the device right?? It says QUERY LCM# failed

Hey piper,

I have the same problem but it made it so half of my screen is frozen and I can't use it, so I can't even type in a passcode to get into my phone. Do you know how I could possibly fix it?

iPhone X: Apple Pay/NFC reader no longer work after replacing other parts

Sat, 10 Jun 2023 14:37:55 -0700

Well... I went through with replacing my charge port battery and screen and now everything works except for Apple Pay/NFC payments/reader. I tried resetting all settings and adding a card back, but I am still at this point. I'm having trouble trying to finding something that would really give a clue as to what I could have screwed up.

iPhone X: Why cellular data is not working after water damage.

Wed, 31 May 2023 14:47:42 -0700

I jumped on the pool with the phone with me. Because a week ago I had to repair the screen myself, the water protection was not there anymore. After using it for 1 hour the screen turned off with an increasing purple filter. I was able to turn the device. After it, I opened it and saw the damage done by the water. There was plenty of water. I disconnected the battery (and remove it) and put the phone on alcohol isopropanol.

After few days drying out with silica gel (for the water). I replaced the screen and it worked since I put the sim card.

It seems out the cellular data is being connected and disconnected all the time. Every 10 sec the data is disconnected and after 10 sec the data is connected. When I call someone everything seems fine. No discconection at all.

iPhone X: Water Damage - Cameras and Flash Issues - Please help troubleshoot

Thu, 30 Mar 2023 06:37:40 -0700

Hi all,

My iPhone X got water damaged. I opened it up and cleaned all corrosion and performed visible inspection with jeweler's loop. The digitizer was bad so I replaced the screen and transplanted the sensor assembly from old screen to new. I am a little suspicious that I might have messed up the sensor alignment, but maybe I am just paranoid. That fixed the digitizer issue but now the front/rear cameras only work when the power flash cable is disconnected. When the rear camera works it is blurry or something is off with the focus. If the power flash cable is connected then the rear cameras will not work. FaceID always complains of issue with the TrueDepth camera in all cases. Leaving rear cameras disconnected does not fix the FaceID or flash issue. Disconnecting the front camera does not fix the rear camera issue. My thought is to try to replace the power flash cable, but wanted to see if anyone else had any experience or ideas on how to further troubleshoot this? Thanks.

iPhone X: I messed up a customers iPhone X touch.

Wed, 15 Mar 2023 19:51:57 -0700

Hey guys,

I had a working Iphone 10 come in for a battery. I put it together and realized i forgot the sheild over the FPC Connectors.
When i took it back apart something in the screen got damaged in the screen and i got a green line threw it.

Ive had to bite the cost and ordered a new screen for the person, but there is another problem

Some of the screen connectors got unplugged while the battery was connected and there is no touch on the screen as well.

What are the chances its a bad screen causing no touch? Or did I mess something else up on the motherboard? I had to lend him my personal phone, and he wants his back ASAP.

Should i order any more parts to be safe? Is there a Filter i may have blown or IC Chip that could order ahead of time to have on hand? I also dont have a board separator and would need to order one if i need to get inside the motherboard.

I am going to use the FPC diode map to check the FPC connector on the Motherboard tomorrow as well as inspect the touch cable better. Any advice in the matter would be appreciated.

Thanks
