iphone 5 stuck on red battery screen

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.

HELLO GENTLEMEN,

I had the same problem too, my Iphone 6s (now about 2 years old) started to stuck in the low battery mode after drainment about 3 months ago. I first thought that it is a simple battery life or dock connector issue. Until I tried to load the Iphone with different devices and chargers. First I started to charge my Iphone at the standard wall-socket, then at my PC, finally I tried a third party powerbank with different genuine Apple USB-cables of course. Nothing helped. My phone was kinda dead and unuseable.

Then I went to the Genius Bar at my local Apple store. They did some very good troubleshooting with me and we finally agreed on a 90 Euro Battery replacement. The replacement happened yesterday.

THE PROBLEM IS, IT DID NOT WORK.

I got my IPhone back, with a 100% charged new battery (I checked that via a Battery-life app). But still, after my Iphone died the first time today (after replacement of the battery), nothing changed. The phone is still stuck on the red "charge me screen", although it recognizes the charger (plug in symbol dissapeares, Iphone is reognized by Itunes ONLY IN DFU MODE while "dead")

-------------------------------------------------------------------------------- -----------------------------------------------------------------------------

SO MY INTENTION TO WRITE THIS POST, DURING MY ONGOING RESEARCH, WAS:

IF YOU HAVE THIS PROBLEM I AM TELLING YOU ABOUT AND THE ORIGINAL POSTER IS SUFFERING FROM TOO,

DO NOT REPLACE THE BATTERY FOR 90 $ / Euro, BECAUSE IT WONT HELP IT.

ANYWAY DO NOT PAY FOR ANY OF APPLES "MAYBE-WORKING"- SERVICES HASTILY

-------------------------------------------------------------------------------- -----------------------------------------------------------------------------

I am still looking for an answer (the heating of the battery via hair dryer or heater is not helping either, the only thing that HELPED ME TEMPORARILY, was to charge the phone with one charger at the socket, interrupt the charging process for 30 mins waiting and then charge it with another charger at my laptop/power bank), a really weird problem, I know.

so thank you all for reading and good luck and greetings from Germany

Hello andrewcsss,

After reviewing your post, I have located an article that can help with your device battery. It contains a number of troubleshooting steps and helpful advice for the issue you are experiencing:

If you can’t charge your iPhone, iPad, or iPod touch

Make sure you’re using Apple-certified accessories and the right power source.

If your battery is really low, you might see a black screen for a few minutes even after you plug it in. Let it charge for at least 10 minutes (20 minutes for iPad). If it still doesn’t charge, follow the steps below.

If the battery doesn’t charge

If the battery doesn’t charge, unplug your device and try these steps:

1. Look at the connector at the bottom of your device and make sure it’s free of debris.
2. If you're using a USB power adapter, make sure it's plugged in all the way and the power outlet is working. If you're connecting to a computer, make sure it's on and can charge your device. To charge an iPad, you might need to use a USB power adapter and plug into a power outlet.
3. Try a different USB cable, USB power adapter, or USB port.
4. If everything seems to be working, reconnect your device and wait for 30 minutes.
5. If your device still doesn’t charge, try to restart it while it's connected to power. If you can't restart, reset your device.

If you see an alert

When you plug in your device, you might see one of these alerts:

• “This cable or accessory is not certified and may not work reliably with this iPhone.”
• “This accessory is not supported by this device.”

If you see one of these alerts, unplug your device try and these steps:

1. Look at the connector at the bottom of your device and make sure it’s free of debris, then reconnect the USB cable.
2. If you still see an alert, try a different USB cable or charger.

Get more help

If your device still doesn't charge or you still see an alert after trying the steps above, contact Apple Support.

Thank you for contributing to Apple Support Communities.

Cheers,

Hi,

I had this problem, i used a heat gun to heat up the back of my iphone 5s for about 30 second and i then pluged my iphone straight in to a wall charger and the apple logo came up. please be careful because it gets really hot. i think the cup of tea or coffee can do the trick as well.

Following a response here that showed how he got his iPhone 5 to start up by pressing it against a cup of coffee, I can say that this works too if you're in a pinch - I simply touched the back of my iPhone 5C that I had recently purchased from eBay against a warm cup of tea for a few seconds, then reconnected it to my computer - it would seem that the cold conditions it was being transported in were making the phone act a bit odd, and it needed just a tiny bit of warmth to wake up properly.

I have a similar battery problem on my wife's 2-month-old iPhone 6+. Here are the symptoms:

1. The phone would not charge beyond the displayed battery percentage, which was 7% in this case. The battery kept draining no matter how long we kept it plugged in.

2. The displayed charge value declined over the course of the day until it came to rest at 1%, after which it only went back to 4% when I connected it to my pc and iTunes started up. That's about it.

3. I did all kinds of reset as found here in the forum. None worked.

4. I backed up the phone using iTunes and did a restore using iTunes. Then, the pc kept making these connect/disconnect sounds and eventually iTunes told me that the device had malfunctioned and couldn't be recognized and needed to be reconnected.

5. At this point I noticed that the phone was caught in the shut down/power up loop. I disconnected from the pc. The loop went away and I was able to set up the phone. Still wouldn't charge past displayed figure- 3%.

6. I plugged in phone all night until morning. Nothing changed. So, I decided to let the phone battery die out so that I could try the hair dryer idea.

7. The hair dryer worked- TEMPORARILY! After blowing hot air on the back of the device for about 3 minutes or so I immediately plugged in the dead phone. The apple logo appeared immediately and the phone booted itself up and showed 100% charge. After about 20 minutes I disconnected the phone from the wall and it died within 10 minutes! I tried the drier a couple more times. Each time, after I plugged in, the dead phone showed the apple logo on and off (like a looped thing) until the phone booted up again, only to show the persistent 1%. It was at this point that it occurred to me that it was strange for a dead phone to start up when plugged in; it should show only the battery icon or something like that along with indication of charging in progress.

8. So, I went online again and found this web page: https://www.mendmyi.com/blog/2014/06/has-your-iphone-5-died-and-wont-charge-or-c ome-back-on-we-can-fix-that/

Their explanation of matters makes sense. They had me examining all the Apple adapters and USB leads at home- we have accumulated quite a good number over the years. I found one cable that didn't pass muster on closer inspection. And it had, by some strange accident, recently been used to charge that ailing iPhone. Wow!

And that got me thinking. Why haven't I found some sort of "official" explanation of the problem, along with its cause, from Apple? Why? Oh, why have the 'isheep' been left seemingly without a shepherd?

Hi All,

I used the blow dryer heat method on my battery (I took it out of the iphone 5c because I didn't want to damage the iphone) and it worked too! Further, the battery that I had plugged in all night, but still wouldn't reach the apple icon, just the battery indicator, showed a charge of 100% once the iphone 5c rebooted.

Since I had another older battery that was exhibiting the same stalled charging pattern (no apple logo, just the battery charge indicator even after several hours of charging) I was going to try the blow dryer method again, but first I plugged the charging cable into the iphone without the battery to see what would happen (you have to have already performed battery removal procedures that exist on youtube from various repair places). After a few minutes, the apple logo appeared, but it just kept cycling through from apple logo to black screen and back to apple logo. So (and probably stupidly...you should never make connections when the phone is connected to the charger) I reconnected the battery while it was still plugged in and cycling through this apple logo process and...it rebooted. Don't know if this is something that will help anyone who is at their final, exasperated point, but when my phone rebooted the battery was at 1% and subsequently charged all the way to 100%.

My iPhone 5s has been having battery issues ever since I updated to iOS 10 (previously on iOS 7). However tonight was the first time it ever got completely stuck on the dead battery screen. I didn't believe the heating method would actually work, but after several attempts holding it over the candle I had burning, it actually turned back on. About a minute of careful heating is what did it for me.

Well actually u need to plug in to ur computer.Connect you device to your computer and open iTunes then put your phone into DFU MODE it will become a black unresponsive screen and then just restore your device.After it is done it may show u the battery screen again but let your phone charge for the whole night.At the morning you shouldn't face any problems.And then if u are facing

Battery problems then it's better to consult apple

About few weeks when I done a software update on iPhone 5 but during the update that when I stuck on red battery black screen. But if left off the charging all day it stuck on 100% then I plugged in charge then it dropped to 1%

I can't believe this worked! I heated a hot cup of coffee up an extra 75 seconds, then held the back right of the iPhone against the outside of the cup for 60 seconds. I then plugged it in immediately and it quickly switched from the red low battery screen to the apple logo. THANK YOU!

**** Yeah... The 'Make your iPhone hot' technique does work. Even my 5S was dead as **** in the office, and I only had a cuppa of Green tea to make it hottt! enough to get restarted. It works... Just put your phone besides any hot object for a minute and it should solve this kind of issue. Thanks Mate.

Andrew, Did you find any solution for this case? I got similar problem. My iphone was showing 80% and within 1 min it is 1%. It worked on 1% for few hours before it was dead. Now my iphone is stuck on red battery logo.

FOR ANYONE THAT'S TRIED EVERYTHING & STILL STUCK ON CHARGING SCREEN:

I found the solution! For reference I have an iPhone 5, and mine went into charging screen after I tried Upgrading into iOs 9.

If you've tried every single thing on the net hard reset, soft reset, cleaning charger port, etc. and still can't get it to get OFF the Charging Screen & You think you need a new battery, TRY this method first:
Let the iPhone completely die. Plug an original iPhone charger to USB cord & into your PC or Mac. While it's plugged in - Reboot the Laptop, this may take once or several trials before the iPhone finally turns on/or into the Apple Logo, eventually you will finally be able to sign onto iTunes, and restore, or restart your iPhone, iPod, or iPad without losing all your Info. Most cases this has worked!

For me, I had to first unplug the battery cord from the motherboard, and then try the same steps. Took me 3x's for it to finally work.
I have watched every single video on YouTube, regarding this issue, and read every thread I could for 3 days, Until I found this in a Forum. Hundreds of people got there's to work. Read their results here:
http://forums.everythingicafe.com/threads/iphone-wont-charge-or-turn-on.16042/
If the link doesn't work go to www.everythingicafe.com search through the forums "iphone wont charge or turn on".

I bought a Battery thinking that was the issue, although my phone will need a new battery eventually ( due to dying quickly ) Nothing has worked

for me, Until I tried those steps. Hope this helped.

My phone was fully charged and docked when the red battery just appeared and would not go away? It's a 4S and a couple of years old, so most likely needs a new battery, which is a simple and inexpensive fix (just google). But I am away in the middle of a vacation, and a huge rain storm from a hurricane, so getting a new batt anytime soon won't work. I tried all the reboot and iTunes fixes, but after six hours on the charger, still a red batt. Then I found this thread about heating the phone to put a slight charge in the batt <http://forums.imore.com/iphone-4s/231912-iphone-won-t-charge-after-battery-drain ed.html>, go to the 16th post by VFRWiz... doing this made my phone alive again, it's all about heating the batt to get it up past the lithium auto-shut down level (which is what the red line battery icon means).

Following is how it worked for me, and my phone is fine now 12 hours later. Do not do this unless you are desperate, it would be best to get a new battery if you can, or into an Apple Store. ALSO be VERY careful not to over-heat the phone, read the entire thread above, as some advise against doing this at all, and there are some other tricks, and finally follow my advice at your own peril:

I used a heat-gun (super-hot & can melt solder, but was very careful not to get too close -most people used a hair dryer) from about 10 to 12 inches away, with the iPhone 4S face down, pointing the heated air at the back right side & edge (where batt is) for one full minute, phone gets pretty hot so be careful, then put the phone back on the charge cord right away. The red battery symbol was immediately replaced with the white apple and a progress bar, then Photos & iTunes launched on my computer and a moment later my iPhone splash screen came up!!! Holy Moly, what a save. NOW THE MOST IMPORTANT STEP: Go get a new battery. Hope this helps someone who is stuck, but do be careful not to overdue the heat, you could damage the phone.

Another post in the middle of page 3 explains the science of the "Heated Battery," which I paste here:

For the Electricians, it's as simple as V / I x R

For the rest of you, Voltage over Current times Resistance.

Basically, heat creates resistance with electronics, and because resistance (ohms) and current (amps) are friends, they increase the value of Voltage.

Example: 30ohms x 5amps = 150volts

If you heat it up, the ohms will rise, example.. 35ohms x 5amps = 175 volts

(note this isn't the actual stats of your battery, just a loose example)

Now because you applied heat to your iPhone battery, or any Lithium Ion battery with a circuit that cuts off when it drains too low, you re-enable the circuit because you charged the battery slightly through raising the resistance inside of itself, thus rising the voltage. (very neat trick, eh?)

Another thing about this funny science thing is... if you are a person who wears a wrist watch.. have you ever wondered why the battery in your watch lasts so much longer while you are actually wearing it all the time?
