Over time, the Apple Watch 4 battery wears out and holds a charge less, loss capacity is a standard situation for lithium-ion batteries. It is not possible to restore the wear of the Apple Watch 4 battery, so the only right solution is to replace the battery in the Apple Watch 4.

Wow thank you Mr how-fixit I am so unimaginably lucky to have found this guide! Now i have the luck of not only having to replace the battery, but now also the screen ribbon cables because i didn't read the comments first. Thank you!!!!

[@martinjurak5966]

This is not a very good tutorial - there is absolutely no need to disconnect the screen. The replacement itself is pretty straight forward - this video just adds unnecessary complexity for no reason.... You do not even need to remove the vibration part during the replalcement. In short, no need to disconeect the screen, no need to remove the vibration part, everything else related to battery removal/replacement is OK (+ screen re-attachment with glue).

[@AdolfBeaz]

Noticed that as well, can you please suggest me a simple video that does the battery replacement quite right?

[@N0M0RENAME]

wouldve been cool to read this comment before I lost track of which screws go where

[@howfixit]

- First, replacing the battery with connected ribbon cables to the display can accidentally damage the cables. Replacing a damaged ribbon cable is a difficult repair that is not worth the watch itself. - Secondly, when opening the watch body, you can damage the Force Touch cable, which will need to be replaced and you still have to remove the display. - Third, removing the vibration module will give a more convenient approach to removing the battery, especially since it is not difficult to remove the vibration part. - Fourth, with the removed display module, you can thoroughly clean the display surface and watch body from the adhesive residue, and it will also be more convenient for you to apply the glue evenly. - Fifth and most important, you can be flexible and follow your principles, this video guide is my approach and you can skip some steps if you consider yourself a pro. My goal is to show the safest repair steps without the risk to damage the device, especially for those who are starting to repair for the first time. Your comment suggests the risk of damaging the device at several steps, and so, you are either a professional (you have some experience and you can skip a few steps, in which case I don't understand why you watch this tutorial) or you have never repaired anything and trying to give an incompetent recommendation. Why not take two extra steps, but at the same time make a quality repair?

[@tgvinfinite2607]

@@howfixit not trying to say you're incompetent or anything, but i read the ifixit guide and they didn't do some of the steps you mentioned. Do you think the ifixit guide is unsafe then, because it looks like its faster, but at the same time I dont want to risk damaging components like you mentioned

[@jorancardon7125]

​@tgvinfinite2607 like he said his replacement is the safest possible way that's why his showing some extra steps it doesn't mean the other method isn't safe this one is just safer and if your new to repair this is the best way to do it lowest risk of damaging parts

[@precisionxt]

That curved screen tool is a life saver. It’s so much easier to lift the screen without damaging the aluminum body. It’s already paid for itself.

[@mblackwe11]

Pretty good video except you skipped the part where you replaced the Vibration Engine.

[@josephdeluca]

I was able to replace the battery without removing the screen or the taptic engine. Makes it much easier and faster.

[@NigkonuN]

How ?

[@martintrevino6688]

Thanks for your useless comment

[@carlocarnevali7790]

Is the process the same for the 44mm version?

[@Koko-qs8zx]

I tore the connector that is on the rubber seal. Can you buy a new one? How do you connect it to the watch? It doesn’t appear like it snaps in. Any help is appreciated….. Thanks.

[@pablin5198]

Hi, thanks for the video. I am writing to you from Argentina, thanks to your video I was able to replace the battery of my apple watch series 4, but I have a problem and I need help. It turns out that I finished assembling my watch and it works, but the screen does not turn off, after a few seconds, it turns off but turns on again. I suspect that some sensor is not good. When I disassembled, a small connector on the bottom of the right side broke.

[@andreacarbonchi6719]

Hi. I just replaced the battery by wading through this video and I have the same problem as you. How had you solved it? Thank you

[@saqibhasan101]

is there a reason people don't use the isopropyl alcohol to loosen the black foil adhesive?

[@TheMalecs]

READ THIS BEFORE YOU START!!!!! You really don't have to take the screen Ribbon Off! You may end upbreraking the ribbon and needing to replace it. This is not a great tutorial. Sorry

[@sinatra617]

So you replace batteries for others? If so how much? My father got had one brand new that sat for a long time. It wont turn on. It was literally never opened or dropped.

[@lardenr123]

Hi done all this but touchscreen not working on the watch now. Which connection would I need to check? Thanks

[@SusanGW]

WOW! Not sure if I can do all of that or not! My battery will only stay charged for about 4 hours. Thanks for the video!

[@dingnextstop]

I’m afraid I tried this and only managed to splinter the screen edges, I have a comple set of Ifixit tools and heated the edges but it was impossible to get the tool under the screen and landed up splintering the glass… no blame on you I just feel it’s a very difficult procedure even though my battery life is almost non existent

[@yaridarison235]

Does it still water proof?

[@ssportslivetvstreaming]

can I put a series 5 or 6 into my series 4 for upgrade battery or not ¿

[@edtilsley]

Do I really need to pull out the black stuff @6'23" ?

[@dawitjohannes]

Thanks alot.

[@justinstewart3248]

The battery you linked for the Apple Watch 4 has a different mah than the one in the video…what do I do?

[@joshrepik]

Higher mah is fine

[@CKTechTV]

What a mess. This would be simply unacceptable in my workshop...

[@jorancardon7125]

Make a video and show us how to do it simple without proof your comment is useless

[@CKTechTV]

@@jorancardon7125 alright then.

[@dwc1857]

8 months and no video.

[@CKTechTV]

@@dwc1857 it's coming...

[@alexi5473]

I did this and the touch screen isn’t working anymore, why?

[@joshrepik]

You didn’t get a flex cable reinstalled fully or you ripped it

[@miltonlino6762]

what's the measure of the tri-wing?

[@howfixit]

tri-wing Y 0.8mm

[@SrssSteve]

The background ‘music’ made this unwatchable for me.

[@CKTechTV]

Nice pun.

[@SivaFolsom]

Totally agreed. Watched it on mute with CC.

[@alexandrevm3]

Thanks.

[@MrAnderson321]

Think I’ll give it a miss.😳

[@justinstewart3248]

I just can’t get this screen off at all

[@shayneoneill1506]

oof. battery glued in. I really dont understand why apple makes it so difficult to replace these sorts of parts. Since Watches are SUPPOSED to be 20+ year jewelry, you'd *think* they'd build them in the understanding it'll need 5-6 battery replacements over that lifespan. So why make the task so fiddly.

[@martinmysak8606]

Isopropyl makes it easy

[@markwarren7959]

They make it fiddly so they can gouge as much cash out of you as possible. Don't fix it, spend another $350 for the next Iwatch.

[@wolfehaund9729]

Because you don't want a battery knocking around in a device or it'll get damaged, also its not a watch its a phone that happens to be on your wrist, it'll last for as long as its capable

[@macuse2008]

Ah good sir Apple wants you to buy a new watch every three years

[@slushyable]

$$$

[@sergeizvol]

Три ошибки при разборке. Показал что открывать дисплей металлической лопаткой в месте где шлейф дисплея в миллиметре от корпуса, мне стоило это 67 долларов. Не показал что открутил ещё два винта крепления платы. Оторвал два провода от медной подложки, которые экранируют помехи на дисплей закрывая шлейфа подключения. Чудо броканик. Тебе говно в канюшне чистить надо. Вообще непонятно как тебя вообще пустили к этой технике. 😂

[@sergeizvol]

How to Brock it. 😂

[@macuse2008]

You could just pony up the $80 bucks and let Apple do it. Guaranteed success.

[@randygonzalez5758]

why does this guy sound like a strip club DJ?

[@cbaker257]

😂😂

[@johnmonk66]

why are you taking it all apart? as soon as you open it the battery is right there! this video is stupid, buy 200 dollars in tools to do something apple will do for 99 dollars

[@patriciaweber9832]

the glue is still there looks so bad..
