I am watching this video in 2021 n there is so much improvements in his work confidence, camera set up n mostly the flow of informations. He is very serious in this video but the recent videos you laugh your lungs out 🙂

Nice repair. And congrats on your anniversary :) Cheers John

@ststele 8 лет назад

Thank you! :)

@naiarapierotto4437 6 лет назад

Hi! I love your videos, I saw most of your stuff online, I learnt a lot from you. I've been in iphone repair business for two years and finally a month ago I started with microsoldering myself. Just a quick question, 5s U2 replaced successfully, but it still same with fake charging and low voltage( but better than before, double), it is annoying me, do I need to look for something else..?

@daveg.9380 5 лет назад

wow just the video i needed my friend you're so young there

@oddity4650 3 года назад

What are them things called that u are pulling off? U call them dudes... the black rubber cover things?

@davidtorres8426 7 лет назад

Hey man Great video you know I wanted to ask you about a job I had today so I replaced Tristar on a 5S as I always do after diagnostic but the phone was still unable to rise a dead battery, so I replaced the IC again and same thing so I checked voltage on the nearby cap (sorry don't rememebr the numbers) and was 5V everywhere required also replaced the small nearby protector ic and even went ahead and replaced the pmic bro nothing do you have any leads? brand new looking phone btw lol

@fixedtech 7 лет назад

Hi Jason I was wondering if you would be kind enough to advise me. I have just done my first 5s tristar replacement. Prior to the repair it worked with a charged battery but not with a flat one and pulled no charge. When unpacking the replacement ic I noticed it was chipped on the edge but I installed it anyway. The job went well with no overheating but the phone is now dead even with a charged battery. Could this be because of the damage to the new ic? Thanks in advance

@ststele 7 лет назад

Absolutely. When these ICs get cracked, any number of things inside can get shorted and cause undesired behavior.

@oddity4650 3 года назад

Interesting u said flat battery, basically i got a replacement used battery, also a new battery, both did not have any charge to them, so I am guessing that even thou I also replaced the digitizer display, ic, charging port, it could be as I need a charged battery, no idea tbh.

@oddity4650 3 года назад

So I replaced a ic, charging port, battery digitizer display, but it is not showing any image on the screen and it is showing no amps or voltage, for the iPhone 5s, any advise to what it could be?

@danielwelsh 7 лет назад

I enjoyed your video. I have a question that you may be able to answer. iPhone 5s water damaged, Emi shields removed, ultrasonic cleaned but phone stuck in recovery mode. I get the apple symbol, then black screen with backlight on then turns off. can't restore get error 5.....any idea what this problem may be

@jonthecont 5 лет назад

the sticker on the other side around the charging port connector peeled up and removed 5 components, ill remember to remove that next time as it took a while to solder them back on. Tri star changed now and all charging

@lequid18 7 лет назад

Hello super tuto !! What is the temperature for desoldering with the hot air station ? What type of welding flux do you use? thank you for your reply.

@ststele 7 лет назад

Thanks! 390C is what I keep the hot air set on. I use all sorts of different fluxes tho.. these days I'm using mostly Chipquik SMD291.

@lequid18 7 лет назад

Hello, thank you for your reply.

@Blitz886 7 лет назад

helo! my ip5s is dead now, it instantly black screen itself after connected to a charger, could it be the U2 IC cause this?

@alexgreer872 7 лет назад

Correct me if i'm wrong , after replacing the U2 IC the voltage from the battery connector should be between 1.3 to 4.2 and you said in the end of the video that the voltage is 0.00 volt which is mean there is no voltage for the battery to fill it ? which is mean that how ever the battery show that its charging it should be fake charring too .

@ststele 7 лет назад

I had accidentally shorted the battery to ground if I remember right. They generally snap out of that pretty quick. I'm pretty sure at that point in this repair, the 0 volt condition was caused by me (without going back and watching my own video). This phone did in-fact charge to 100% after this repair :)

@ststele 7 лет назад

This one was a lot of repairs ago.. I may have that battery short confused with another video? I see a lot of zero volt batteries from Tristar faults be revived without anything other that connecting the charger after the repair . You guys are gonna make me watch my own video! LOL! You're the second one to say something but I know this phone was absolutely working and reviving itself from a stone dead state when it went out the door.

@madsure. 2 года назад

5s and 5se does it have the same charging ic, which is 1610a3?

@gemos7777 7 лет назад

One question.. I have one iPhone 5s which drains battery in standby mode 2-3 % in 5 mins. It doesn't get hotter. What can be the reason? Is it u2 chip? Replaced battery still same problem.

@antonmeden6334 8 лет назад

Good explantation, what kind of microscope do you use, how much do you have zoom. Where do you buy it? Thanks, greate job.

@ststele 8 лет назад

Thank you! That's an Amscope microscope - it's 7x - 45x. Purchased on eBay.

@mixxx2005 7 лет назад

Hei, love your channel and attitude in general. I have a problem with iphone 5s. After lcd change - backcamera and flashlight failure. Is it possible that U17 is ruined by statistic or I should look in different place? Greeting from Latvia ;)

i have 5s, no lcd picture, filters all good, changed lcd driver ic at the back beside nand chip, fpc connector good, what can it be?

@fineart8927 7 лет назад

Hello Jason, do you know why my phone would have rapid discharge? I've replaced the tristar 4 times and it still is discharging fast. I've tried a known good battery too and it still discharges abnormally fast.

@artman102 5 лет назад

Water damage corrosion somewhere.

@jaytrip3770 7 лет назад

I have a 5S that was water damaged. Have cleaned the board with isopropyl and removed all corrosion. It now turns on. But it doesn't seem to charge properly. If battery dies, when phone is turned on it goes into bootloop until I restore it through iTunes. Currently not charging past 6% but I have seen it charge past this, but then battery dies very quickly. There's a few dirty looking capacitors on the back of the logic board.. I assume u2 and have bought a new chip to replace with but I am unsure. Is there anything else I should check before attempting an IC repair? I'm learning so go easy on me !

@artman102 5 лет назад

You must practice this repair on old boards. You will mess the pads at first. Some tristars have very hard solder and take a lot of heat and flux. You can damage nearby components. Prying off the tristar takes practice. If you have an old board you can remove and replace different chips for practice.

@rafaelaguilar1329 7 лет назад

iphone 6 plus ic u2 5 pins are damages could i made a jumper only to charge the battery

@ronaldr2693 7 лет назад

where do people usually purchase all these types of ic chips and filters from? some people say digikey.com but searching for the conventional name like Tristar (U2 IC) shows up as nothing.

@ronaldr2693 7 лет назад

thank you so much. greatly appreciated.

@wojc4339 6 лет назад

Hi, I'm watching Your videos for some time now and I'm having an issue with my Iphone 5s. The phone is not charging, not connecting to computer but when it's turned off, battery plugged in and I'll plug the charging cable the phone is starting. I've changed the lightning port for a new one, but this didn't helped. Can You please give me some advice where to look for problem and how much would it cost to fix?

@ststele 6 лет назад

I'm betting this one would wind up being the Tristar IC at fault. Unfortunately, I think you can buy a 5s for about the same price as what we fix them for though. We charge $95 + $8 return shipping.

@wojc4339 6 лет назад

Thank You very much! I'll search for another one :)

@chsunil206 7 лет назад

bro can u solve my problem . my iphone 5s is charging very slow and not showing charging sign bt still charging very slowly . what should i do

@_kemal_z 7 лет назад

How can I check whether to u2 chip? By measuring the voltage at the battery connector and switch on charger? Wont turn on.... If you can help, thank you.

@ststele 7 лет назад

Hey, hopefully you have that one figured out by now. Tough to keep up with all the messages and emails. I generally go by the behavior of the device and eliminate dock connector as a possibility. Many times I replace the Tristar IC as a diagnostic check to see if it was bad.

@FYNT_SEVERE 7 лет назад

how much does this cost

@vinstoncoelho6711 5 лет назад

Hi guys can anyone help me? I have a problem that is I have a iPhone 5s which died on me one day and won’t turn onn. No matter how much I leave it to charge, even I left it overnight and still did it turn onn so I replaced the battery and the device turned on and also started to charge but it holds charge for only 5-6 hours even thought its 100% charged and then dies again so I thought it could be faulty battery so I replaced the battery one more time and same problem drains the battery within 5-6 hours even if I don’t use it at all. Do you’ll think it’s a charging IC problem?? Thanks

hello sir my i got an iphone SE thatse wont charge after water damaged! iv removed the shields and cleaned with the unltrasonic machine ! the little resistors next to the battery connector seems gone! should i get these resistors? or replace the u2 is enough? hope you can help me!

@nayefalkurahi3357 6 лет назад

will a 6s that drains fast but charges normal at ~.70 Amps and even from dead battery . Be a bad u2 chip? i tried multiple batteries and charger ports and restores but drains within 2 hours

@ststele 6 лет назад

+Nayef al kurahi there's a lot lot of things that can cause battery drain. I have seen it be Tristar but I've also seen it be audio IC as well as others. Those can be tricky to chase down.

@myxmusic1822 6 лет назад

Can you help me with my iphone 5s please. When my phone manually or auto-lock after a few seconds it turns off by itself and i need to press the home button and lock button simultaneously to turn it on again sometimes it boot loops to apple logo when i turn it on. I tried the DFU mode and restore it but its still the same problem. Help me!

@artman102 5 лет назад

Water damage somewhere, or someone knocked off a chip somewhere.

@filipeaugusto1269 4 года назад

if i change the tristar, i lose my personal data anda photos?

@ststele 4 года назад

Tristar doesn't contain any data so there should be no data loss.

@filipeaugusto1269 4 года назад

STS Telecom My iPhone 5s are in lopping, so its probably that the problem is on the tristar?

@tomasvavrecka3801 5 лет назад

Hey! How did you know it's 100% Tristar?

Check your symptoms, they are listed on the internet.

hello nice videos can you please show me how to remove the back peace from the back from iPhone 4s ??? please help me or show me a video how to please thank yo bless

@RebelBoy-bk5yc 7 лет назад

To remove the back glass from a 4s their is 2 "pentalobe" screws next to your charging port. Remove them and slide the glass up toward the power button and you should be able to lift it and remove it from the phone.

@carlossmith2500 7 лет назад

I'm asking cause my phone was working perfectly I put it to charge for a few minutes when I got back to it .. nothing worked... so I'm guessing that it could be the battery..
