My Problem

Had to replace the battery in my 3GS, phone was dying anytime it wasn't plugged into a charger, even if the battery said 100% it would die and I would have to put it on a charger to get it to turn back on

My Fix

Was nervous that I would end up with a paperweight, but it went very smooth, I just followed the guide every step of the way, the only hiccup I had was that I do not own a hair dryer, so removing the old battery took longer than expected, that "mild" adhesive they have on there seemed like it could hold a car together lol, but I finally pried it out and everything else went perfect, the phone is acting like it did the day I first got it!

My Advice

The tip about a magnet for the screws was an awesome idea! They are so small and I know I would have lost half of them if not for that tip! So thank you so much whoever thought of it, also use a hair dryer to loosen the glue holding the olds battery in, it took me about an extra 10 min. Just to get the old battery out, do it the easy way if you can

My Problem

The home button on the phone was not working.

My Fix

the repair went a bit bananas at the begining. I replace the part and one of the internal cables was not doing good contact so i could not use the slide functionality on the screen. I reopen the iphone and connect carefully the cables again. Then it works.

Iphone 3g works like new.

I can see that the screen is not the same type as the original one but it work so i will survive.

My Advice

it si a challenge but it was fun.

My Problem

No matter what charge level the battery was at, phone would just shut down. Could not restart phone with out putting a charger on it. Apple store wanted way too much to replace battery and ATT wanted a 2 year contract for a 99 cent replacement phone. Did not want to get stuck with contract with IPhone 5 coming out before 2 years was up. Needed a GOOD solution. Found a GREAT one with Ifixit.

My Fix

I got my kit at 5pm and by 5:30 job done and phone works like new again. The guide was so well writen and the photos so helpful in visualizing the instructions that anyone can complete this repair.

My Advice

Unless your IPhone is under warranty Ifixit is place to go for replacing your battery.

My Problem

My iPhone's battery was dying. I had to charge it twice per day and some days even three times! I had to change my battery.

My Fix

It was a thirty minutes procedure and imagine that it was the first time opening my iPhone.

My Advice

If your battery needs replacement don't even think about it. Just go for it!

My Problem

After two year in operation, my phone was not retaining battery charge. After three months form the starting of the problem, even with battery on 100%, after using some software the phone re-boot. Some time it went from 100% to 0% asking to re-charge, and other times, after re-booting it worked a little after die again.

In the beginning, I was thinking that problem was related to IOS 5 update. Latter, when the problem escalated I started to suspect on the Battery. The problem worsened very fast after few months and It was almost impossible to use the phone without a battery-case (DEXIM). First I would like to send the phone to replace the battery, but it would cost me much more than I would like to pay and I would have to send my phone to other city and wait almost one week to take it back. So I decided to replace the battery myself.

The problem? It is hard to find a Battery spare in São José dos Campos SP - Brasil. There is some place that has, but I did not have much reference.

My Fix

First I would like to thanks everybody who shared information on this site and also to IFIXIT for the very good guide and also shopping experience. First I had a little issue because the system did not accept a billing address different from the shipping one. As this was for safe reason, it is okay. After sending a Fax the order was accepted and everything worked fine.

The repair - I followed the guide step by step, but I still faced some difficult in the beginning. First my display was not getting off, even using the suction cup. Second, after I opened the display, I have problem do disconnect the connector. Before I found the correct way, I removed the label of connector 1 (it did not damaged any thing). After studying the guide and the video, I realized what I was doing wrong. After disconnecting the first connector, the task become easier. I take all the advices posted on this forum, I have prepared the place, I had a Hot Air in place (it was not necessary in my case) and the only other issue I have was that I damaged a little the DO NOT REMOVE tag and I had some difficulty to connect connector 3 (I connected, but did not know if it was enough).

My Advice

My Advice? Take some time preparing your self before starting the battery replacement. The first time is not so simple as it seems looking the video and if you damage some thing, it is worse. Also, I recommend the Heavy_duty Spudger. I almost did not use the original one that comes with the kit. Most of the time I used the heavy-duty one.

My Problem

Same problem as many others - phone shuts down randomly at 70% power. Lots of blather on the web about why (new iOS, etc. etc.) but the only solution that appeared to actually solve anyone's problem was battery replacement.

My Fix

No problems with the replacement. Pay attention to where the cable under connector 3 actually is before you release it. When I released the little white flap the whole top came off and I didn't really see where the cable had come from. After some fussing on the rebuild side though I got it into the right place. Hardest part is getting the logic board with the camera attached all back into the correct place. That took a while; just stick with it and use that spudger to push the camera down into place when you get it oriented correctly. Although I bought a 4S before attempting this repair not being too confident in my computer repair abilities, I now have an operational 3GS that I'm hoping to get ATT to unlock so I can use it overseas with prepaid SIM cards from local carriers. That part may be harder than the battery replacement!

My Advice

Be brave. Keep the screws separate in the same pattern as where you took them out of the phone.

My Problem

The backlight on the 3GS was dead, and we have to make it to November before we are eligible for the phone upgrade, so we ordered the display assembly and followed the instructions.

My Fix

Mostly just like the repair guide shows. One issue and recommendation.

My Advice

The #3 tab is very small and difficult to discern. There is a black band across the top of the cable, that is NOT the piece you are supposed to lift 90 degrees. In front of that bridle is the tab that you GENTLY lift to release the cable. Ours was white.

For older eyes, use your digital camera in close up or macro mode and take a picture of the area before you try to release the #3 cable. Zoom in on the picture and you can see the mechanism much more clearly.

Inserting the tab on reassembly takes some dexterity, but eventually the cable will slip into the slot, and then just be sure the cable is fully pushed forward before pushing the locking tab back down.

My Problem

My iphone 3GS is almost 3 years old and for the past few months, it would shut down at about 60% battery life. I was super frustrated so I searched online. I found ifixit, watched the tutorial, read the reviews, and decided to order a replacement battery and tools. I figured $40 was cheap to get my 3GS working.

My Fix

It took me about 45 minutes but I was able to install the new battery and reassemble my phone. And my phone works great now! No more shutting down at 60% and it lasts the whole day!

My Advice

I would pay close attention to the connectors before disconnecting (take mental or actual picture). Also, pay attention to the screw next to the camera since there is a small metal piece attached to it.

The best advice in another review is, generally "pull harder and push harder than you think is ok." This helped me a lot in reconnecting the tiny connectors.

Thanks ifixit!!!! I would highly recommend this product and instructions for the iphone 3GS battery replacement.

My Problem

Dead battery

My Fix

Smooth

My Advice

For that price, everyone should make it

My Problem

My 3GS battery life was slowly getting worse and worse to the point where it would only last me half the day before I had to recharge it. This was only using the phone for texting and general internet browsing...if I actually had to phone someone then the battery would likely die between 4-5 hours of use. I was going to send it into the Apple store, but decided I was more tech savvy than that and could replace the battery myself (with the help of iFixit of course).

My Fix

Repair went very smooth. The picture tutorials offered by iFixit are fantastic! I've had to make tutorials for other things so I understand the difficulty and time that goes into making good, coherent tutorials. The process took a little over about 2 hours, which is longer than it should have taken, but this was due to me studying the insides of my iphone because I've never taken one apart before.

My Advice

The spudger is ridiculously useful. If you never use it again to disassemble your phone you can absolutely use it for other electronic endeavors where tiny baby hands are needed but unavailable due to restrictions on child labor. I was hesitant on ordering one since it looked like a basic piece of plastic, but it is most definitely worth it!
