My iPhone 5 keeps turning off randomly?

I have an iPhone 5 as it says, but I've been having some trouble with it recently, it keeps turning off randomly, when it has at least 40% battery, and it won't turn back on if I hold down the sleep button, it sometimes but only rarely turns back on when I hold down the sleep button and the home button for ten seconds, but 90% of the time I have to plug it into the charger or wait about half an hour for it to turn back on, has anyone else had this problem? It just started randomly, I haven't dropped it or gotten it wet or anything, I only got it in January, thank you In advance.

Probably just a glitch from apple, try taking it to an apple store or call apple about it

Not much I can say other than you should have gotten a galaxy s4…

Happens to me too. No cure yet

Yeah this is the exact problem that i'm having with my iphone right now i asked help on their technical support on their website and suggested to update my o.s. Since mine is outdated, i just updated to the latest os. Hopefully if fixes the problem if don't i gotta bring it to apple

Same problem. When you take it to an apple store they tell you to wipe all your data!

Have had this problem several times during the past year - apparently it's a glitch with the 5. Happened today with it showed 83% charge. First time it's happened when I had more then 50% charge. Not upgraded to IOS 7 - did not see anything in the materials about it addressing this problem.

I have been having the same problem. Talked to both Verizon Wireless and Apple, they tested the battery and Apple had me back it up to ICloud and then restore it as a new phone, but it is still happening. Very frustrating and neither place will even talk about replacing it for me because I didn't spend a wad of extra money for insurance!

The same thing happens but some days it doesn't happen and then randomly when I'm on 30+%. However I have always thought it was because I have many apps running on my phone ie. Facebook, twitter, snapchat, instagram. It doesn't help when snapchat basically kills the battery which needs to be fixed.

I'm having this problem too it is very annoying

Having the same problem. Plugging it in won't turn it back on. It's been happening more and more frequently. I have insurance but I think this just made up my mind to switch to a Galaxy.

All this is not helping we all have this problem but no reply from apple as how to fix this does anyone really know what to do?

Having the same problem.

This happened to me too. I got my sister's old iPhone five and now it won't turn on. In rarely turns on when I'm even connected to a cord. This is happening to my new iPhone 5. I think this might be a glitch for iPhone 5's cause my friend with an iPhone 4 and my dad don't have this problem. It is annoying because my mom doesn't belive me about this problem

The issue of an inability to get my I phone5 to turn on once it goes to the Dark Side has become really annoying! Today was the 3rd time in about 6 weeks. My phone is just useless the past 5 hours and maybe longer the other times it happened. I'm not going to sit and stare at a useless phone. UGH!

Talked to Apple tech the other day for same issue on iPhone 5S since updating to ios 10.3.2. Press both the sleep/wake button at the top and the home button simultaneously for 10 sec. Or a little more. The Apple icon should appear and the phone will return to normal function without losing any your data or info. If it happens a 2nd time ( as mine did), do a backup on iTunes on your Computer to your PC or iCloud. Then, restore your pone from back up. I did this last night and am waiting to see if it solves the issue. I was told something may have happened when installing the update to make it so buggy, but a large number of people seem to be having the same problem. I suggest everyone with this issue call Apple tech and let them know.

It happens to me all the time it goes off in the day a lot and never comes on until i connect it to the charger and leave it a few hours but for the first time today i held the home and power button for ten sec's or more and it came on but that's the first time that's happened

To Serge: Yeah, let's all switch to galaxy phones and have them blow up in our pockets! Good idea! I wouldn't have a Samsung if you gave it to me for free, and oh yes and their washing machines caught on fire all by themselves, too… Good products! Cheap junk!

Same bs

Completely shut down?

Me too its annoying

Derp, this is how they force upgrades.plant these bugs in older equipment.

My iPhone5 has been acting up now for about a month… Shuts down… Comes back on… Okay for a few hours… Then does the same thing again. It was off for 5 hours yesterday. I'm solving this irritating problem… Buying a new phone, but not an iPhone!
