Solution To Your Charging Problem
Chances are you have an issue with your Charging IC chip on your iPhone. When this chip fails, you will see low amp draw from your phone when it’s charging. A typical iPhone should charge at 0.97 amps, but when this U2 IC chip fails or is broken, the amp draw may be 0, or very low 0.3 or anything below 0.5.
At CaseMogul, we can fix this issue for you by replacing this chip with a whole new one! The cost of this repair is $100. But we will rule out that it’s not a charge port or a bad cable. We also carry a 90 day warranty on all our repairs.
What causes this issue?
Typically speaking a bad cable is the main culprit, many times you would plug in your phone and it just dies, or you plug in your phone going to bed and wake up to find your phone isn’t responding or turning on at all. The best advice is to buy Apple OEM cables, there are critical chips that help regulate electricity when you are charging your phone. When you are charging your iPhone, the cable and phone work together to regulate the electricity, and if you have a cheap cable, it runs the risk of releasing unstable current into the phone thereby damaging components.
If you absolutely don’t want to spend $25 on a lightening cable, try to go to a reliable supplier. We have seen customers come in claiming that they’ve used apple OEM cables and still have had the same issue but it’s more common when you buy that $1 cable at 7-11.
On a side note, Samsung phones seem to have built in charging chips that handle all the responsibility of regulating current. So having a cheap cable doesn’t really affect anything!
Error 27 on iTunes
If you encounter error 27 on iTunes, this basically means there is no path to data. Meaning you will have to go through a full restore. Usually speaking, if there was no other damage to the phone, this should be all you need to do. You may have to put your phone in DFU mode before connecting to iTunes.
- Plug in your iPhone, iPod touch, or iPad to your Mac or Windows PC.
- Make sure iTunes is running.
- Turn Off your iPhone, iPod touch, or iPad if it isn’t already.
- Press and hold down the On/Off button on the right side (iPhone 6 or later) or top (all other iPhones, iPods, and iPads) of the device for 3 seconds.
- Swipe the slide to power off slider to the right.
- Press and hold down the On/Off button on the right side (iPhone 6 or later) or top (all other iPhones, iPods, and iPads) of your device for 3 seconds.
- Press and hold down the Home button on the front of your device while still holding down the On/Off
- Keep holding both buttons down for 10 seconds. (If you see the Apple logo, you’ve held them too long and will need to start again.)
- Let go of the On/Off Button but keep holding the Home button for about 5 seconds. (If you see the “Plug into iTunes” screen, then you’ve held it too long and will need to start again.)
- If the screen stays black, that’s it! Your iPhone, iPod touch, or iPad should now be in DFU mode.
Replacing Charge Ports and Ripping Pads on Charge Ports
We’ve all been there where we just start figuring out how to solder and we end up replacing an old charge port but the metal pads that are stuck on the motherboard end up coming with it. Ripping pads on motherboard is a pretty common thing in the beginning, but over time you should get better and you shouldn’t be ripping any pads at all.
Why do I keep ripping pads when replacing the charge port?
The motherboard pads are ripped because the solder that connects the charge port prong to the motherboard has not all melted. It may seem strange but the solder on each little pin actually melts at different speeds. Why? Take a look at the picture with the two arrows for me to explain.
The connectors on charge port are connected to the motherboard, but each piece of the motherboard that each connector is connected to is different in sizes! For example, the connector under the orange arrow has a tiny tiny little piece of the motherboard connected to it. You can barely see it but it’s essentially a small light green dot that’s walled off by the dark green colour. The connector under the blue arrow however is connected to a much larger light green surface. Because they are attached to different sized light green patches, it should make sense that as you apply heat, the heat takes longer to heat up a larger green patch than a smaller green patch.
That’s why just because one connector solder point has melted doesn’t mean the rest of them are melted! We have to wait until the connector that is tied to the large while connector. In many cases the (ground wire) is fully heated before we can safely life off the charge port!
Have no fear! If you do ever rip pads, you can always send them our way and we can clean up your mess of ripped pads!
S6 Edge or S7 Edge glass screen protectors lifting
As smartphones have slowly shifted to having curved surfaces, it’s been a real challenge to provide the same amount of protection as “Tempered Glass” but at the same time making sure the screen protector stays on the phone. Given each screen on each phone itself is made ever so slightly differently it’s been a real challenge to have proper tempered glass installed without it lifting in a matter of a few days!
We’ve found that if you apply a regular screen protector first and THEN apply glass screen protector, the hold is a lot stronger! Since we’ve used this new technique, there’s been far less issues with lifting glass screen protectors for curved phones.
