Samsung Galaxy S21 - Battery replacement [including reassembly]

[@yott1950]

This is the best and most detailed step by step video I've seen for replacing the S21 battery. Danke schoen!

[@CurtisAkerstrom]

Why can't all KZbin tutorials be this thorough and easy to understand? Great video

[@georgeponcedeleon8754]

Thank you so much for this video! I was a little unsure if I should change the battery on my phone by myself, but after watching this video I was able to successfully change the battery.

[@Zerkoto]

Such a detailed and beautifully explained video! Thank you very much for the guide. I am sure I will need this in the near future as the battery is already draining fast. I also love the fact that a girl is doing the tutorial ❤ It's so rare to find a technical video that is not made by some Indian guy and I never expectde to see a girl 😁. Subscribed to the channel! Keep it up giiirl :)!

[@D191969]

Excellent tutorial! Now I know for sure that I will not attempt this repair myself :)

[@DefJamDead]

Still rocking my S21 in 2024. Only spent £20 on repairs. £10 today for a battery replacement. Last year £10 for charging port replacement. Great phone!

[@mrdripz1095]

Did you repair it yourself

[@mrdripz1095]

Replace the battery by yourself?

[@vvurx]

thank you. you explain everything clearly, i replace the battery by myself and everything works great.

[@daviddrew7624]

Great video, I'm replacing the battery on my s21 ultra, only thing I'm doing different is I've cleaned off the old seal from the case and back cover so I can put a new seal in place 👌

[@FareedAhmed-v5l]

Thank you. Amazing instructions. Blessings and good will to you and your team

[@fcon2002]

What beautiful voice and accent.

[@alysson478]

Thank you, your tutorial helps me to make my phone has a real long life

[@GianmarioScotti]

At 6:16 I already decided this is not for me. I'm going with Fairphones from here onward.

[@zoomermcboomer4771]

This is much better due to the plastic back rather than the glass which is prone to cracking more easily. I did this with my s9 when I had it. The problem is that I replaced the old battery with a crap, chinese one and it was arguably worse than before. I don't know where I can find good quality replacement batteries especially for older phones.

[@fearless6947]

yes a lot of the batteries on amazon and ebay used cheap ones. The also put a new cover tape on top of the old one. There is a youtube video about this problem, which I didn't know about before. Even with the seller with lots of great reviews. The youtube video is titled.....It's all a sccam - before replacing your phone battery watch this- scams explained. KZbinr Hugh Jeffreys. I guess it depends on the seller but seems like a lot of sellers do this. It sucks but maybe go back to Samsung or iphone manufactor or time to upgrade. It depends how long you used the phone for.

[@TristanVash38]

I've never heard a country european accent before. Interesting!

[@dobermanguy9437]

It really ticks me off that manufactures have these battery sealed inside the phone I much better like back in the day where you could just pop out the the battery the guy who says they do this so your battery doesn't pop out when you drop it that's total BS most of us have our phones in a case anyway so you wouldn't have to worry about that they do this so you go out and buy a new phone !!!!! because they know 90% of the people are not going to bother taking a phone apart to change a battery trust me it's also you go buy a new phone

[@lp4625]

I wouldn't recommend using a suction cup on the battery. There is a flexible wrapping around the battery, and using a suction cup could (probably will) ruin the wrapping and comprimise the battery. In my case, it caused a small hole/rip somewhere and by using the suction cup, I pulled air into the wrapping. I know this video is about changing the battery... so your battery might already be bad... but I was hoping to move the battery to another S21+.

[@lluismac9614]

Hello; Good tutorial, it seems easy, the question is that the S21 comes with a 4000mAh battery that lasts very little for a day with normal use, can it be replaced by others that sell 5000mAh batteries, is it convenient or inadvisable? The brands that sell it are LOCONCOER, Da Da Xiong, HSABAT which you recommend or discourage. Thank you.

[@mephisto86yt]

The claimed capacity is not real. Always replace with an original battery.

[@CarmenLopez-vn9lm]

i live in the US where can i purchase original battery?

[@zumbatan550]

Excellent. Thanks

[@pyro9973]

Hey for anyone curious and a little bit anxious about the NFC here is a solution I came up with and also tried instead of just "removing it" you can unscrew the top and bottom and with a slighlt lift on the top and a spudger you can remove the flex cable and remove it as a one whole unit. Remember, the screws are all the same so mixing anything up doesn't cause harm. Here isa little pro-tip from me about screws, before you screw them in try to screw it in the opposite direction till you hear a small "CLICK" sound so you do not demage the thread for the screw so you have in the case you have to replace the battery again your screws are still in tact. For anyone reading this comment in the future and needs help with the removal of the battery hit me up and I will give you a cool nieche trick to remove the battery.

[@CMG02]

I did not find an s21 battery on your website.

[@iDocEN]

Hi CMG02, here you can find the original Samsung Galaxy S21 5G battery. www.idoc.eu/en/samsung-galaxy-s21-5g-battery Best regards iDoc Berlin

[@CMG02]

@@iDocEN thank you.

[@Emiror]

I did it! Thank you!

[@svenb1520]

U can use solvent to remove the battery

[@MegaFCKforever]

dosen´t the guarantee stop if you just as much as try to pull the backcover off ?????

[@pcofranc]

Yes warranty could be void but won't need to change battery until out of warranty 2+ years in most cases. Other option take phone to authorized repair center.

[@sjstu]

Is possible to warp the screen during heating the battery adhesive?

[@pcofranc]

No. Watch JerryRigEverything as he burn tests screens by putting a flame to the screen. Don't do that but heating the screen to where is is up to ~ 200 F is fine. I purchased T-7000 silicone adhesive tube and glued my screen on and use painters tape overnight and it came out perfect.

[@ivystrickland8760]

did anyone's phone get hot after replacing the battery?

[@zuheyr1]

Can we buy this kit from you as well as the original battery but *for Samsung galaxy s21 ultra*. Can you make a vidéo for 21 ultra?

[@dobermanguy9437]

It doesn't matter what Samsung you have they're all pretty similar the way they come apart if they are glued in this is what you got to do

[@eggsammich1186]

Is there a way toheat the phone without the gun?

[@pyro9973]

A hairdryer but it takes longer. Here is a quick tip, heat it up to a point where you can touch it but it's not very pleasant for long. You can also try run a game on your phone while doing that to heat it up!

[@USDM_Jesus]

My only concern is the water resistant capabilities

[@0...00..19]

I think she stated the water resistance won't be up to the same standards after doing this which makes sense

[@robertdavis8578]

I wonder if a 4.5 lb. hammer wouldn't be a less frustrating solution? 🤣🤣🤣

[@lapisfix]

no need to remove everything tbh and adding Isopropyl alcohol to the sites of the battery will help loosen up the glue and its best to re apply glue when putting the back cover of the phone

[@suzio6571]

This is the worst phone I have ever owned! I'm not a technician and have no idea WHY it should be sooooooo difficult to take the phone apart. I WILL NEVER BUY A SAMSUNG PHONE AGAIN! SWITCHING TO IPHONE, AS SOON AS I CAN.

[@seankossila6478]

Iphone is even worse.

[@Wolfy-tp1wr]

lol are u lost why are you even tryna open your phone its ment to be like that so it doesn't fall apart when you drop it

[@acanofspam4347]

LOL yeah uhh... good luck with the iPhone 😂

[@TheMikePho]

Buy an LG. Much easier to replace battery and the batteries last much longer.

[@suzio6571]

@@TheMikePho phones actually running a lot better these days. I took into the shop. I don't remember what the problem was now but the guy fixed it😁
