iPhone 8 Battery Replacement - iPhone 8 Battery Repair How To - Simple Guide 

First of all thank you so much for the great video! Best one on RU-vid in my opinion for changing this battery. I looked at many, and this is the most complete and concise including cleaning and replacing the seal and applying the double sided tape. Secondly… Awesome accent! A pleasure to listen to during a stressful rookie attempt

by watching the delicacy of the steps taken, I will never dare to attempt to replace battery. You're amazingly skilled to replace the battery.

Clear and thorough guide. Thanks! BTW, I set the playback at half speed, which made it easier to follow.

Thank you! I was able to flawlessly switch out the battery in my daughters phone thanks to your video!!!! Well done, amazingly thorough and decisive instructions! Thanks again!

Guides like this should start with a warning!! Make sure you record where each screw comes from, and where they should return to! The screws vary in length, and if you put a long screw into a shorter hole, it will go down too far and damage the circuit board immediately below. Apple does this to hamper phone repairs.

i never comment on youtube but i thought i would this time, thank you so much for this tutorial! ill admit it took me 4 hours (fighting with the screws and loosing one) and doing the "pry of shame" because i didnt buy isopropyl with the nozzle but but other than that this was very clear and very easy guide to follow. so, thank you!

Excellent video, which should discourage people from me from threatening the life of my iPhone.

Damn my old iPhone 8 was on 71% max capacity and I’m tryna fix it to sell it thanks

That was almost to much for me and my old eyes !! But thanks to your great video I was able to complete the job !!

Thank you so much. Perfect tutorial. I was able to change my battery to my Iphone. :-)

Very excellent video, much appreciated to replace the battery in my phone. What I can’t find is the first seal/ adhesive that is put in before the battery and seals the surrounding edges of my phone. I can find the two strips but not the bigger seal. Could you please tell me if that seal has a particular part name or number? Cheers Yvonne. Ps I am 70 soon do quite impressed with myself as now my phone still works 😊👏👏👏

Very well done... Really like the small pocket friendly size of these older iPhones so I'll give it a try to keep it going a bit longer! Thanks :)

yes thanks you made it look easy but my clumsyness and first go took a lot longer and i cant be sure the seal whent totaly to plan but i did it with yours and others help , you get the thanks as you did the seal bit as well unlike most others so many thanks for your time and help for a first timer 🙂cheers

This made up my mind. I thought about changing it myself. I'm not cheap, I just like to fix things. First I really don't want to buy brain surgery screwdrivers. Maybe if i had a need in the future. Now having just turned 67 I have gotten along just fine without them. Add in the not so steady hands. I believe I'll just watch the young man install it. If he lets me. Very well done and very understandable narration. Subscribed and a thumbs up.

Close and very helpful. My kit came with a suction cup to separate the screen. It said to heat the phone up with a hair dryer for 90 seconds first.

I just had my battery replaced today and an apple certified place in Canada, and I’m curious about the waterproof seal is that the blue tape that somehow applied a waterproof bead around the phone or?

Great Video On iPhone Repair. It's nice to see a good POV to further my knowledge

Thank you for breaking it down. Very helpful

Yur videos are really helpful

Hello, Battery on Iphone 8 has not a BMS chip ? Condition of battery is visible after replacement ? Thx.

So this was WAY more informative than others... and shows the actual install... It's a lot of work. But you made it look easy (and I know it's not). Sharing is caring!!! xxx/ooo 👍

Don't be fooled by this video. This is a very cavalier crash course guide. It's a very delicate job and can take several hours if the adhesive strips put up a fight. Cover your screen with something to protect it from scratches. Don't lose the screws and remember which ones go where. The adhesive strips under the battery are a bastard. They won't come out nice and easy. Apple made sure of that. Alcohol makes it more difficult to scrap them out clean. Warm the bottom of the phone instead. Clean with alcohol after you get the pieces out. Connect the battery ribbon cable and install the battery before you put the screen adhesive sheet on. Be very careful and take your time positioning the screen adhesive sheet. You'll only get one shot at getting it perfect. When reconnecting the ribbon cables, be gentle but make sure they're connected properly. You'll feel a positive click and check they're fully engaged by pushing down on both sides with the plastic tool. The little screws don't like to stay on magnetic screwdriver bits very well. Position them with tweezers first. When starting them, it's always a good idea to turn them counter clockwise a turn or two before turning them clockwise to ensure you don't cross thread them. Before you set the screen and close up the phone, test it. Make sure it powers up, and that the home button and front camera work.

Very thorough and helpful tutorial. Thank you. 99% IPA isn't common in the US. Normally only up to 91%. Will pure methanol work in place of the IPA?

My mom’s iPhone 12 Pro has 85 percent battery capacity! Have a replacement ready to go once I goes down 80 %

After servicing the battery the phone says it's unable to determine battery health. I'm wondering if it's something in the iOS updates (16.8.8) that's causing it?

Good video. However I was not using isopropyl but ethanol and in the end noticed some lens fogging on the camera despite drying up the phone with the hairdryer before closing. So it’s now in a ricebox with extra silica gel on top for a day or two with open sim slot. Also you don’t have to pry with anything sharp. Just use hairdryer around the edges and use a suction cup.

Fantastic instructions.

Thank you!

2:49 I accidentally scraped that black stuff under the battery a little bit. So its like a 5x5mm or a lil smaller scrape mark on the black ”film” thing... Will that affect the phone? Or will it work anyway?

great knowledge thanks for sharing 😊

1:23 which screwdriver you use ?

Great video man

Do a video of screen burn-in fox please like self fix it

Great video

Thank you, I have 100% again

How long phone/baterry hold on 100% capacity, on one charge.

Good video, clear voice and no wasted time, I'm gonna give it a try. Thanks

Hello❤️.my iPhone 8plus just cut completely off and it’s not charging or nothing.does that mean my battery health is dead?

Great video! I’m also going’s to replace my battery with my local repair shop but will the phone no show “battery not genuine” and will 3rd party battery show battery health?

Does replacing the battery in a iphone 8 with a non apple battery give some kind of warning messages or any percentage health displaying issue in ios 16 and higher?

Excellent guide, thank you.

Thankyou .. works well.. excellent work.

hi why do copy batterys not show the health

Can I do this with the display still attached?

Can i upgrade my iPhone 8 battery? From 1,821 to 2,200 mAh? Is it safe? What is it negative effects?

The battery was from Apple or any other brand?? Is it ok if I use a battery that is not from apple? Will I still be able to see the battery health?

Just one question, whenever I press the home button some vibration happens but loud and I don't know what piece is that or part, don't know if it has to do with the home button or something else... can you guide me???

Would brake cleaner work as the achool ?

Great

Very helpful! Thanks so much!

The hardest part was getting those extremely tiny screws into place. Had one fall into a crevice and was really hard to get out. But I finished the operation

Awesome video, thanks!! Have a nice weekend.

thx for sharing :)

do u need the apple id after it finish?

Do a video of how to fix screen burn

No tag on flex or programmer?? i was told i need to get a tag on flex

What is the liquid you are using to remove the glue?

Well done!

Hey Man how do you Fix camera shake in iphone? Using magnet inside iPhone 8 is a good idea?

Where can I get the main iPhone 8 battery to replace my phone please?

yoooo ima fix my phone in a month (currently mentally preparing myself by researching and rewatching tutorials) so that i could give it to my younger sister for her birthday hopefully i dont fuck up since this is my first time ever trying something like this 🙏 does anyone have any beginner tips i need to know before i attempt to do this?

i replaced my battery on my iphone 8 and the life on it still sucks compared to back in the day when i got the phone, Wish apps did not require new IOS versions to update the apps…. it forces you to update your ios causing the battery life on older phones be worse each updated …

Are all the screws the same size?

Went well, until I put it back together and now the home button will not work. Took apart and reconnected all of the cables. Still nothing. Ugh.

Do Adhesive sheets come with the battery?

Bien echo ❤

I change battety, but now wont work home button, selfie camera and top speaker… whats wrong?

That’s nothing compared to my phone which is at 77% capacity

"Authorized service provider only" It's my damn phone, and I authorize myself. 😅 At least this model is old enough they haven't serialized every component.

The maintenance video is very detailed, I learned a lot, it is very helpful to me, thank you for sharing. If you need mobile phone repair tools, please contact me.

Excelente trabajo saludos 👍🏻

Excellent guide. He makes it look so easy. If you follow step by step, you should have success. Of course all of my battery sticky tabs broke off and i had to pry the battery out........

Is it critical to use 99.9% pure Isopropyl Alcohol? I have 70% on hand and I would have to order 99.9% from a special supplier. I guess 70% would take longer to dry off, and might leave a trace of water behind, perhaps I could allow a few extra minutes it to dry off.

Mines only work when plugged in

Best instructions out there. Thank you.

So im not gonna have to worry about that error message that the newer phones get?

Is it normal that the phone heatup when the battery health is around 85%??

Can you please do mine.

Yoo where does the tools sell

What is that liquid?

why is music in everyone's background

Alcohol will not damage screen?

how many mAh is the battery

First of all no one in their right mind would have a battery replaced that’s at 85%. Second.. he did a lot of unnecessary shit. You don’t remove the screen, you don’t remove the internal screws, and you don’t mess with the adhesive. I’ve done this for years.

But does it display the non genuine battery message??

CAN I USE IPHONE 7 BATERY IN IPH 8

Never ever use paper to wipe your phone. It leaves tiny scratches over time. Always use some cotton cloth.

My phone healt is 78%

Bye bye Ip 67 and now your phone does not worth like before in its price. It is an opened device. Serviced.

Mmm- I’m at 51% - getting my replacement battery today

nope it does not work that way.

Mine is 77

Mine 62 😢

Also are battery was about to explode

I have an iPhone 8 and if I watch RU-vid, it only lasts for 2 hours, maximum.

Me who’s at 75% 🗿

If need a helper for work plz contact me. I repair phones too🙂

My phone at 72%

what a pain in the butt.

It looks like a bit easy for him to replace the battery. LoL. It's possible he's already replaced that phone battery too many times. Because it does not look like that the first time you place it. 🥴💩
