Q: iphone 5 stuck on red battery screen

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. 

Battery with thin red line stuck not charging. Tried hard reset then cup of hot water on back of iPhone 5 for 15 minutes plugged in, no success.  Unplugged and used hair dryer medium setting for 30 seconds and went to plug into charger AND APPLE LOGO RETURNED AND HAD 13% battery showing and now charging.  Thanks.

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..

OMG!!! IT WORKED WITH MI iPAD!!!!

I'm at work so i don't have a hair dryer at hand but I used the hand dryer at the ladies room and IT WORKED!!!!!

Thank you so much for the information

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 ... I was not having my hot tea ... so kept the iPhone 5 out in the balcony with its back facing the hot blazing 112 F/ 40C sun for two minutes ... held the Switch on button ... and voila ... there comes on my dead since 4 days iPhone to life ..... !!!!

I have a iPhone 5s, same problem, stuck on battery screen for 5 hours. I heated a cup of water in my microwave for 1:30 minutes, put the iPhone on the cup, and voila!!!! appeared apple logo and phone lived again!!!!!

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!

this has happened ti me and im stuck on  the red battery sign.. i have tried all my chargers... any help ??

Thanks for sharing this trick.  I followed it and was able to access the phone again.

Thanks.  I just tried this with my IPhone 5.  The first time it did not work but I did it again applying more heat and it turned on as soon as I plugged it in.  About 80% charged.  My IPhone had refused to start for two days.

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!!
