Hi there, I often do iPhone repairs but i have a question about an iPhone that is showing strange behaviour. This iPhone 4 just goes black all of a suden. I doenst repond to anything, its not working at all at that moment. Also a reset is not possible at that time. It is not possible to power on the iPhone. Only when connected to a charger is can go on. When its on everything is working fine, shows up in iTunes etc. I replaced the battery with a new one a did a software recovery. Still the problems accur. It doesnt seem to matter if the phone is connected to a charging source or not, it just shuts off random. When the phone is on everything is working normally. Another thing that i noticed, when its shuts down you wont see the spinning circle that you would see when manually powering off the iPhone, it just goes dead inmediatly. When the phone is powered off manually, it will also go on the normal way. When it shuts down itself this is not working The battery is working fine, the phone accepts and charges it just like normal. Home & sleep button are working perfect. Any ideas what to do with this
UPDATE** The iPhone is now constantly fibrating, it was charging on my pc. Now it wont go on but keeps fibrating :S When putting the iPhone in DFU mode and try to recover it gives errors. like ‘2005 and 106’ Any ideas? Any help would be apreciated
The battery terminal may be damaged therefore the battery cannot charge nor supply the phone with power but when the power cable is plugged in it powers the phone directly. You can check if this is the case by removing the battery and connecting the charger then if the phone powers on this idea should be correct. Kind regards Brad
hi i have an iphone 6 plus that only stayed on with charging wire even though the battery was showing as almost full . When i opened the phone the battery seemed to have expanded slightly (damaged most likely). Replaced the battery for a new one and it is now fine.
This sounds like you got water or damaged the Doc connector where the charger plugs into so its not charging the battery so when you unplug it just dies straight away. replace the doc connector and take it from there as the battery is next in line! i got one for a fiver on ebay!!!
Try to clean the contact between the battery and the phone, press hard on that contact and power the phone with charger disconnected. if it powers on you can install a small plastic bumper on top of the contact and than n force the cover on it will crate some Pressure . good luck
i think you need to replace the battery connector.But you need to know about microsoldering.iFixit has a video series about microsoldering.They have a video that they replaced the iphone 4s battery connector.But with the iphone 4 the process is almost identical.
ITS the Battery…the reason why it’s randomly turn off…the reason your having iTunes error is because when the phone goes to restart itself it will not because the battery giving you this error and battery’s are real tricky almost everyone who sells battery’s say oem or original but even Apple has a lot of complains about battery’s…lithium battery’s are out of date and Easley breakable but ohhh well there cheap to make!
If you take Ito the Apple Store they will just give you a new iPhone but make sure your phone is backed up so you can just transfer everything to the new iPhone
Probably there’s a loose battery connection. I have to reconnect the flex cable on mine.
Kimberly iPhone will be on an battery all the way up the screen will be on an you see I tunes an when I stop miss with it an put it down it will go in sleep I guess an I have to plug it up to back on put battery is up what that mine ???
I had the same problem. Device would die a few minutes after autolocking. Only plugging in the lightning cable would turn it back on. It still has full battery after turning on. Eventually it would stop charging altogether whilst displaying the charge icon (lightning cable was plugged in, and tested on a second device to be functional). This occurred several months after a battery replacement. Turns out I had applied too much solder on the battery contacts. This caused the black sticker covering the soldered contacts to tear and the battery shorted itself against the aluminum battery cover. The fix was, open it, stick black electrical tape on the underside of the battery cover directly over the battery contacts. After putting everything back together. It charges properly and doesn’t turn off after autolocking anymore.
Still happening in 2020. Just got the iPhone 12 last week and was almost done putting all my accounts in. Connected it for charging and an hour later pulled the plug to look something up. Black screen, no reaction, nothing, dead. Connected it to the charger again, bootloop. Apple logo, black screen, apple logo, black screen, apple logo, black screen… Connected it to the old USB A to lightning cable and got it to boot. I was able to do a backup and reset the device that way. Problem is still there. In a few hours I’ll be at the Apple store. … #notamused If you have the same problem I think the old cable is the only way to get your stuff. USB-C to lightning seems to do something “clever“ that allows the bootloop to happen.
I have same issue in my iPhone Xr. I get 3rd party battery replaced after this problem start. Battery backup is good. But when i turn on camera at full brightness. It does suddenly turn off some times and power on until i do connect to charger for only few second. Can anyone help me plz
I had the same issue. I deleted a large percentage of internal memory - backup files - problem solved.
