Below are specific topics we’re bringing for you today:
Problem 1: iPhone 6 overheating issue
My 6s Plus IPhone is overheating and less than a minute after switching on, it “boils” in the upper right corner so that you can hardly touch it on the back. A message appears that it has to cool down after overheating. I unfortunately dropped the phone a few days ago and it also updated the software to IOS 10. Not sure if any connection. I read that software update can cause heating but this is abnormal as it hardly switches on. If I go to Airplane mode there is no problem, but switching it off for LTE or just the WIFI immediately causes to heat up very fast. Switching Data off does not help, I did twice a full restart of the phone setting to factory settings and wiping it completely. Same behaviour, no heat in Airplane mode and beaten up after a minute if it is switched off. I am at home with very good reception signal and WIFI with many other devices working very well, so the idea of the phone overheating as it looks for the network is not working. If there is hardware failure what is the parts I should try to replace in the first place? I opened the phone and the heat is in the area where the screen cables connect. — Raphael.charit
Solution: Hi Raphael.charit. Overheating issue can occur in any electronic device although it’s much commonly experienced in smartphones and computers as they tend to require huge amount of processing power to do some tasks. Knowing the exact reason why a device gets too uncomfortably warm varies in every case. For some, it can be due to a software glitch, malware, or problematic content (app). In others, overheating can be a direct result of user misuse such as accidentally dropping the device, exposing it to moisture or water, or leaving it near direct heat source. Since you are the owner of your device, you should have full knowledge of its history.
For instance, if your iPhone was accidentally dropped before it started to overheat, there’s lesser chance that the cause is software in nature. You are most likely facing a hardware malfunction, which can be anything at this point. A failing battery is, however, not far-fetched in your case. If the drop dislodged the battery or broke some connections, there’s a chance that some components may encounter problems either due to shorting or lack of required power. A drop itself won’t directly damage the battery. It’s the other things connected to it, or even the connectors itself (cable) that may suffer. Once there’s a short inside, the battery can then fail indirectly after the direction of power between components become erratic.
If a factory reset did not help fix the overheating problem, that’s an indication that you have a hardware problem at hand. Since our blog does not provide hardware troubleshooting and solutions, we suggest that you let a professional service the device so proper assessment can be done.
Problem 2: iPhone 6 keeps rebooting on its own, can’t complete full restore
My iPhone 6 keeps rebooting to the point where I can start a restore with iTunes, but a minute or two into it, the phone reboots.
History: iPhone is 2.5 years old. Six months ago, the battery would start suddenly draining FAST, like 24% then within a couple of minutes 12%, then another few minutes and 1%. I would plug it in to charge it and within 30 seconds, it was showing numbers like 48% or 66% charged. I lived like this for a few months and 2 months ago, had the battery replaced at Staples. It helped some, but not much. And the iPhone kept getting slower to respond and lock up for a few seconds here and there many times a day. Yesterday, it went into a reboot loop. I went into DFU mode and reset the iPhone… it reset it and put the latest iOS on it. Now, when I try to use iTunes to restore it from the backup, it starts the restore, but a minute or two into it, it reboots so it doesn’t finish the restore. Sometimes after it reboots while connected to my PC and iTunes, it’ll start to sync, but then after a minute or two, reboots again. — Cash
Solution: Hi Cash. Like Raphael above, you must be having a bad hardware situation here. If the battery has already been replaced but the phone continues to reboot on its own, or won’t even complete a restore process, there must be a motherboard issue causing it. We suspect it’s a power management IC problem because this is often the first component to die out due to a number of reasons. We’ve seen power management integrated circuits go out after subjecting the phone to a power surge. In some cases, this IC can suffer slow death if your phone charges erratically. Current or voltage fluctuations can kill power IC in the long run too. We know that it’s hard, even impossible for an end user to know which of these possible scenarios is true but a quick check by a trained technician can confirm if our hunch is correct. Power IC failure is often the second most common cause for random reboot issues even on non-iOS devices after software failure. We don’t think yours is caused by software failure though since your device can attempt to restore itself at this point. What is most probably happening is that the phone can’t simply stay stable enough because the power IC can’t provide a stable power supply to other components.
Be sure to let Apple service your device so you’ll know the real deal.
Problem 3: iPhone 6 black screen issue, won’t turn on
Yesterday my phone would not turn on at all. Nothing. It wouldn’t reset either when i pushed the home & power buttons at the same time. I tried to restore it through itunes multiple times & it wasn’t detected. When i went to bed last night it was finally recognizing the phone and was doing the restore. When i woke up this morning, the screen was blue and itunes said that it didn’t restore because no device was found. I did it a 3rd (or 10th) time this morning & it says the restore was done & my phone is detected on itunes, however, my phone still will not turn on. When plugged in it buzzes like it’s supposed to, but the screen remains black. Please help! — Amgrassi
Solution: Hi Amgrassi. Let’s make one thing clear here. iOS troubleshooting is very limited and there’s only so much an end user like you can do. Also, iOS troubleshooting is only possible if you can turn the phone on. There’s no magic trick to revive the phone if the main reason for the failure to boot up is, say a failing battery or a dead motherboard. So how would you know if there’s a hardware issue at hand, you may ask. Well, it’s simple. Here are a few things that you should do:
- Press and hold the power button for at least 10 seconds. This will verify if indeed the phone fails to turn on.
- Repeat step number 1 when the phone is connected to a charger. Sometimes, a battery can lose total energy in its circuit for some reason but leaving the device charged for at least an hour may revive it.
- Check the phone for signs that it still powers on such as charging or LED indicator, vibration, or sound.
- Try using another known working Apple charger. For an issue such as yours, it’s very important to check the possibility that the charger may be to blame. If you have another Apple device or iPhone, make sure that you use its charger to charge your iPhone 7.
- Check the charging port if there’s any telltale sign of damage such as bent pins. A bad charging port will obviously not allow normal charging so after the battery has drained all power, the phone may be unable to charge because due to a bad charging port.
If your iPhone remains dead, or the screen remains black after doing all these, you can bet you have bad hardware. Contact Apple for support.
Problem 4: iPhone 6 plus iTunes 4013 error
Am I completely out of luck? Friend gave me his old 6 plus a few months back. I shattered the screen a month ago. A cell phone repair store replaced it and we discovered a non-Apple battery inside and it was swelling. He said to replace that too. We did and now the new battery is also swelling and if I try to restore my phone through iTunes, I get error 4013. Is this phone now a useless brick to toss or is there someone, somewhere able to fix it or perhaps even myself. HELP!!! — Monica
Solution: Hi Monica. First off, iTunes error 4013 means usually occurs if there’s a problem between your phone and a computer that hosts the iTunes program. It usually indicates a bad cable but it can also be a charging port issue in your phone, or a USB port in your computer. Try to use another USB port and USB cable when connecting your phone to iTunes.
Secondly, you yourself witnessed that the phone’s hardware was tampered with. This means that the previous owned may have attempted to repair the phone and failed at it. The current issue can be caused by the bad battery, or by something entirely unrelated but critical in making the phone stable. Unfortunately, there’s no way for us to know where the real problem lies. If you think the device is worth a couple hundred dollars, have it checked by a professional so proper repair can be done. Otherwise, you may just have to accept the fact that you have a paperweight in your hands.
