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.

Can't believe it! But yes indeed the coffee cup trick worked. I've been having crazy issues with my battery (much like mentioned above) so I decided to do a battery calibration. I was going to let my phone go totally dead on its own, then do an 100% total recharge without interruption (not unplugging it, putting it on airplane mode) and then rebooting. Well, I got as far as letting it go totally dead. Then when I went to do the recharge, it would not charge. Just the red battery symbol. Tried different cables, different outlets, soft reboot, hard reboot.... nothing... just the red battery sign. So I grabbed a cup of coffee.... rubbed the phone on the side of it (back side of the phone) on the cup of coffee for about 30 seconds.... then plugged it in and WHAM! It started up. I've got it on airplane mode charging now. I'm sure I'll need a new battery soon I'm sure..... but I'll see if this works. 🙂

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!!

Holy crap! The heating thing actually worked! My iPhone five has been experiencing insane battery glitches since the last update and was stuck on the red battery screen-- despite being plugged in all evening. I couldn't connect to iTunes to do a restore, so I've been stuck for the past two hours. However, found this post, added some heat from a nearby heating fan and -- VIOLA! Restoring iPhone as we speak. I can't believe this trick worked.

This helped me alot, thanks!

I found it strange that my battery level stayed at 1% the whole morning, so I decided to restart the phone. After restarting the battery level stayed at red.

After applying your heating trick I was able to start up my phone, many thanks!

I Did updated my ios from 8 to the newest 9.2.1 , perhaps in my case this was the cause..

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!

Thank you! My IPhone 6 was on the charger all night. I didn't use it all day but grabbed it to go run errands and saw the red battery icon. I put it on the car charger...nothing. Came home and did the obvious trouble shooting to no avail. Plugged it into my laptop and iTunes didn't recognize it. I'd been on line all evening trying to find a fix. I'd already made an appointment for service (the nearest authorized spot is 1 hour away) for tomorrow but the only available time, other than days away, was going to mess up a prepaid gym session. I'd already flaked out on this session last week and didn't want to miss it again. I have weekend plans that will require trains and the subway and I rely on my phone for getting around, finding food, etc. I read your post, turned on my wall heater and held my phone up to the heater for a few minutes. It came back on. I'm going to read further to try to understand how this worked. Woohoo!

To add...I continued to have problems with my phone. Same thing at least twice a day. Red battery icon. Phone won't hard reset. Putting on charger has no effect. However, remove phone from case and hold in front of wall heater and it comes on. The battery says 29% or something equally low. I put the phone on the charger and it immediately jumps to 100%. I take off the charger and it rapidly drops down to 65%. A few minutes later it says 80%. It's all over the place. I couldn't get an appointment at the Apple store and I couldn't mail in my phone because I needed it because I was going out of town for the weekend. I got an appointment with an Apple Tech at a nearby Best Buy. The Apple Tech ran a check on my battery and said it was fine. He seemed confused about what the problem was. How to you explain this problem without sounding crazy??? He said to go home, do a factory reset and do a restore from the cloud. I did these things. The phone was fine for a few days and now we're back to square one. The same problem over and over. I'm debating whether to make an appointment at the Apple Store or pay the deductible and get a new phone.
