Apple Watch Series 7: Not booting after battery replacement

Tue, 02 Jul 2024 08:35:41 -0700

I just replaced my bat using the instructions on ifixit. The first night, I had it going to the low battery screen like it’s starting to charge. I let it sit there overnight, it’d occasionally ding like it was seeing a charger and show the apple logo. When I took it off the charger it stayed on for ~5mins then shut down. I couldn’t get it to come back without putting it back on the charger. Today I opened it back up to see if I had something connected wrong or something, and now all I get is an apple logo that shows up for a few seconds and then fades out. Can’t even get to that low bat screen anymore. Any thoughts on what troubleshooting steps to take next would be greatly appreciated.

Apple Watch Series 7: Apple Watch Display Remains Black After Battery & Screen Replacement

Fri, 14 Nov 2025 05:28:17 -0700

Hi everyone,

I’m experiencing an issue with my Apple Watch after performing a repair. I’ve replaced both the battery and the screen, and while my iPhone still displays a battery percentage (around 50-60%), the watch itself remains completely unresponsive. There’s no vibration, sound, or any sign of activity when I attempt a forced restart using the buttons.

I’ve inspected the flex connector for the screen, and everything appears to be correctly connected, with no visible damage or misalignment. Despite this, the screen stays black.

Has anyone encountered a similar issue? Could the watch be effectively “off” even though the iPhone shows battery information, or might there be a problem with the new screen, the flex connector, or even the logic board? I’d appreciate any insights or suggestions for further troubleshooting.

Thanks in advance!

Before the repair, the watch’s display had intermittent issues. Sometimes, it would turn off completely and then turn back on by itself after a while. The touch functionality was also unreliable, occasionally failing to respond properly. Eventually, the screen stopped working altogether and remained black. That’s why I decided to replace the display. I also replaced the battery because it was old and inexpensive, and since I was already opening the watch, I thought it was worth changing both components.

Regarding the flex connectors, I initially left the latch open, but I have now repeated the process completely. I removed the battery, reconnected it, and this time made sure to properly close the latch on the flex connector. After that, I connected the display, ensuring the correct order (battery first, then display). Despite this, the screen remains unresponsive.

What could be the next possible cause? Could the issue be with the new display itself, or could it be something else on the logic board?

Apple Watch Series 7: My apple watch resets throughout the day + Scroll wheel issue

Wed, 11 Oct 2023 21:14:01 -0700

I was wearing my apple watch to surf once a week for a couple of months. Shortly after, I began to notice mishaps with the watch. I presume it may be because the watch was worn in salty water too often? I was under the impression that the watch should be fine to wear while swimming. The scroll wheel sometimes doesn't register the scrolls or clicks and the watch will reboot randomly throughout the day. Sometimes as often as once every 30 minutes. Is there something that can be done to fix the issue? I tried doing a quick search to see if anyone else has had a similar issue but I couldn't find anything. Thanks!

Apple Watch Series 7: Will I be able to repair rear cover adhesive without front assembly?

Thu, 22 Jan 2026 07:19:11 -0700

I found a guide for replacing the rear cover/sensor on the Apple Watch Series 7 that instructed removing the front display and battery for swapping the rear cover. However, I do not need to replace the rear cover. It is still functional. The watch charges in the sensor works, but the gasket and adhesive sealant failed and The gasket is hanging out of the watch body, see the attached picture.

Am I missing something other than the rear cover adhesive for this repair.
Will I be able to do this repair without removing the front display and battery?

Thanks for the help!

My watch isn't turning on. The only time I see it display anything is when it's on the charger, but it only shows the Apple logo for about 10 seconds before going blank for another 10 seconds, then repeating. How can I get this watch to work normally?

Apple Watch Series 7: Terminal locations for key functionality, and suggested repair steps

Mon, 28 Jul 2025 15:40:50 -0700

Hey All!
I'm new to personal device repair, but I worked as a repair technician in the medical device field for a few years. As such, I wanted to test the waters with my Apple Watch. I have intermittent battery and screen issues, with some small signs of life. Is there a guide, not on how to fix the device, but on what terminals and wires should be tested to determine which sections of the device are functional?

I have issues with the screen being black 95% of the time, and the charger not charging an equal amount, but occasional signs of life, such as the alarm going off once, and occasional haptic feedback when the watch accepts a charge. I believe this would require at least a battery replacement, and possibly a screen replacement, but I would appreciate information on how to test these failure points before buying replacement parts.

Thank you!

Apple Watch Series 7: ECG not working after backglass replacement on apple watch s7

Fri, 09 Aug 2024 12:04:23 -0700

Hey did someone replaced their round backglass of their apple watch and knows how to make the ECG work again? All sensors work fine, the crown works just fine, but the ecg doesn't work - doesn't recognize the finger

thanks, so might the solution be to glue the sensor on the backglass? (haven't done that yet, I just put the Backcover on to see if the sensors work) there is a white circle with 2 connection points, these than should be attached probably with the backglass?

So they’re basically charging me for a whole new apple watch. They just said the whole thing was broken. Is there a way i can fix it myself when im not sure which part to work on? When i took it in it looked like the screen was what was busted. I could still see ghosts of images on it but i would get haptic feedback when holding down the non-crown button. It broke down THE day of the warranty expiry. :(

Apple Watch Series 7: Possible to swap LTE antenna from US watch to support UK network?

Mon, 28 Feb 2022 06:07:42 -0700

I have a 45mm Cellular Series 7 watch purchased in the US. It will not connect to my home UK cellular network because the LTE frequencies used in the US are different to those in rest of world.

The US model number is A2477

The Europe model number is A2478

I’m trying to discover what parts differ between these two models and whether it would be feasible to swap the parts (antenna I guess?) to get my watch to use my home cellular network.

Does anyone have any experience of doing this?

Apple Watch Series 7: Display remains off after replacement

Wed, 24 Sep 2025 13:34:32 -0700

Hey everyone,

A week or so ago I managed to replace the battery on my 41mm series 7. Hurray! Or so I thought.

I initially powered it on without reapplying the screen's adhesive, and unfortunately when reopening it things went wrong and I ended up bending some of the display pins, which resulted in the display not turning on.

I ordered a new display from iFixit, followed the instructions to replace it (disconnecting the battery first), and after putting everything together the display still remains black while the watch is on (I see its battery in iOS and I can mirror its screen with the accessibility settings.

Anything obvious I should look for? I double-checked and the screen connectors seem to be fully in (see images).

Additionally, just want to make sure I got this right and the connector with (1)

should go in-between the taptic engine and what seems to be the housing of the crown? (2)
