iphone 5 stuck on red battery screen

Hello, recently my iphone 5 has been having weird battery problems. Sometimes it will loose 25% in seconds but last one 1% for hours at time. I forgot to plug in my iphone last night and woke up to it dead. Its been plugged in for a few hours now and still shows the red battery screen. Some things ive already tried are testing the charger(it works on other devices), holding home and power for 30 seconds, and putting it in DFU mode. When i put it into DFU mode it just becomes a black unresponsive screen and i have to hold down the power and home button for 30 seconds just o see the red battery screen again. Any help would be greatly appreciated.

iPhone 5, iOS 7.1.2

This is a hardware defect that is quite common in the iPhone 5 and is now appearing in the other devices that use the lightning charging system. The usb logic ic, called U2, in the iPhone 5 is easily damaged by unregulated voltage swings that pass through non-Apple chargers---especially cheap car chargers.


The symptoms of U2 failure are: rapid battery drain, auto power on at battery reconnect, inability to charge a stone dead battery, fake charging, no usb detection, hot spot at U2 chip. Any or all of these symptoms can occur with a U2 failure.


This chip is encapsulated in a not-meant-for-removal black underfill substance that complicates our ability to replace the chip. There are a few places in the UK and Europe that can change the U2 ic chip, but as of early December 2014, there are no US repair shops that offer the service.

Having tried a bunch of traditional stuff, all the way to attempting recovery mode, the hair drier worked, phone woke up with 35% charge ( it had been on chargers while attempting to wake it) and allowed a factory reset. Time will tell whether the battery needs replacing, it has been misbehaving for a while, suddenly "draining" etc, or whether the heat has reset the battery chemistry.

EIther way, the hairdryer works brilliantly and fast, for at least a functional period of time.

keep regular backups!


thanks

Wow, heating the back of my iphone 6s plus with hair dryer for one minute does the trick for me. The battery had died completely coz of my laziness and refused to come up even after 5 hours of charging. After heating with hair dryer, it didn't come up immediately. But I did put the phone back on charging immediately after heating and waited with crossed-fingers while searching for my old 5s and putting its drained battery on charger with both phones having same screen at that point in time. 🙂 However, got pleasant surprise when I heard the notification sound on my 6S plus. So, heating an iphone with dead battery does work. For those interested, 5s came up automatically without requiring any heating!

I had the same issue last night with my iphone 6. It was stuck on black screen with red battery symbol. This morning I tried searching on net for any solution before taking it to apple service. I found this If your iPhone, iPad, or iPod touch won't charge - Apple Supporthttps://support.apple.com/en-us/ht201412. I tried to clean up the charging port which had lot of debris, garbage in it. Then plugged into power and surprisingly it worked!!
