iPhone 14 Pro Max: iPhone 14 Pro Max: NominalChargeCapacity 3910 mAh vs MaximumFCC 3298 m

Tue, 11 Aug 2026 19:23:52 -0700

Can BMS data on an iPhone battery be reprogrammed in a way that makes Battery Health show 91% while Analytics reports an unusual MaximumFCC/NominalChargeCapacity relationship?

recently bought a used iPhone 14 Pro Max. Battery Health is 91% and normal usage backup is actually good. But when I leave the phone unused, especially overnight, it loses around 8–9% in 6–7 hours.

I checked Analytics Data and got:

MaximumFCC: 3298 mAh

NominalChargeCapacity: 3910 mAh

Cycle Count: 726

iPhone Battery Health: 91%

So NominalChargeCapacity is much higher than MaximumFCC, and the shortcut calculates 118.56%.

Is this an abnormal/invalid Analytics reading, or could it indicate a replaced, rebuilt or BMS-programmed (“boosted”) battery?

Also, is the 3910 mAh reading consistent with the 91% Battery Health?

iPhone 14 Pro Max: How to replace the NFC antenna in iPhone 14 Pro Max?

Mon, 03 Aug 2026 04:13:21 -0700

I was trying to replace the rear glass panel of my iPhone 14 Pro Max when I started to see the NFC antenna fall apart. The rightmost (or bottommost) solder connection seems to have been disconnected. The magnetic array surrounding the coil peeled easily. My screwdriver was making scratches on the magnetic coil. I highly doubt NFC remains functional.

Does anyone have experience or a guide on how to replace the NFC antenna for newer iPhones? I searched a lot on YouTube, but the only videos I found address older devices, such as iPhone X, iPhone XR, and iPhone 11 Pro Max.

Here are some photos of what my NFC antenna currently looks like:

iPhone 14 Pro Max: iPhone 14 Pro Max restarts randomly after screen repair

Sat, 01 Aug 2026 21:37:54 -0700

Just randomly restarts every 5 or so minutes. I checked the battery connector and display connector. I did rip the front assembly connector, but I was told it would be fine without it. Just the proximity sensor wouldn’t work

iPhone 14 Pro Max: Will my iPhone 14 Pro Max start without the Front Sensors?

Tue, 28 Jul 2026 07:11:09 -0700

Yeah, uhm... long story short... I completely smashed the Front Sensor Group whilst trying to change my display, and am now wondering if I need it, or can just let it out? I know about some of the drawbacks of not having the sensor group installed my question is just will it start if I just don't put one back in.

This is the torn apart sensor group (Rest in Peace)...

...with the Original display I just removed.

iPhone 14 Pro Max: Pink Screen of Death after housing swap

Fri, 29 May 2026 08:59:42 -0700

I swapped the housing for a customer on an iPhone 14 pro max with an OEM/Pull housing from a well-known supplier. I have done so many times without any issues. This time I am getting a reboot with a pink screen every 2 to 3 minutes. I have the panic log, and it points to the power flex. I would like to know has anyone had this issue and is it normal for the power flex to function but, still cause panic? I have another power flex and wireless charging flex on order.

panic(cpu 1 caller 0xfffffff048921f84): SMC PANIC - ASSERT: target/d74/target.cpp:266: 0, SMC BSC failure, spreadsheet ver(*10) 150

S.sensor array 0 - 4 is 0x0, 0x100000, 0x0, 0x0, 0x0

F.sensor array 0 is 0x0

F.sensor array 0 is 0x0

The power button flex on an "OEM" housing with small parts was causing the issue. Swapped it out and no more pink screen of death.

Thu, 26 Feb 2026 10:09:31 -0700

This is the log About 3 months ago I ran a van over my phone and the screen broke, so for a month after the phone was a little cracked it continued to work, I went to change the screen, I had been put a 60hz LCD screen that started to make a purple screen and restart the phone but it didn't happen always only once a day, then for a few hours it restarted every 3 minutes, so after about two weeks I had another 120hz OLED screen installed the problem persists every now and then it restarts and then it doesn't restart for 3 or 4 days what can I do I don't want to change my phone?
