IPhone 4s turn off whenever the battery reached 20%

I really sad about my 4s. I bought it 22 days ago and the battery is okay. But now, when it comes to 20% of the battery percentage, it will turn off the phone. When I charged it, it will continue to 21%, 22% - 100% .. I try to restore and everything that I could; nothing is changed.

Let me know if I should start a new discussion instead of opening a new topic here.
My wife's iPhone is the same vintage as mine 3Gs, but has never had the battery problem. Its affliction instead is that it cannot detect WiFi networks unless it is quite close to the source. Often, when my iPhone not only detects but shows a maximum cells connection with a network, hers cannot detect the network at all. In contrast, her iPhone seems to detect ourcellular carrier just as well as mine does.
Is there any help for this affliction?

Why does my iPhone 3GS turn off when the battery charge is only as low as 70%?

After my iPhone 3Gs has been fully charged, whenever that charge drops to the 50% to 70% range, the phone turns off. When I try to turn it on again, the Apple icon appears the first few times, followed only by a blank screen each time -- the home button does nothing. Beyond those times, when I try to awaken it, I can see a faint design that includes a plug, a red battery and suggests it is out of charge. This also happens if I depress the awake and home buttons concurrently.

I just got my iPhone 4 a week ago, and I realized that whenever the battery reaches 55% or less, it automatically shuts down. I have to charge it again to turn it on. I won't turn on unless there is an external power supply to it. Why is this so?

I got my iphone 4 a week ago, but i realized that whenever the battery reaches 55% it automatically turns off and will not turn on unless its connected to a power supply (AC charger or USB on pc). I tried hard resetting it but it did not work. Havent restored it. Any idea why is this so? I hope it has nothing to do with the battery.

Hi,
Not that's not normal and is one of the Problems I was having before Restoring as New...
Just make sure you Sync ALL your important Info... Contacts... Music... Etc... to your Computer...
and then do a Restore as New...
i was a bit reluctant at First, because I hadn't done it before... But it was So Easy and am Really Glad I did...
Cheers,

My iPhone 4S was turned off when the battery got empty, and when I put it on the charger it didn't charge at all. I tried restarting it (on/off home button for 10 sec) nothing happened except it kept giving me the "charge battery" on its screen.

Hi! My iPhone 4S was turned off when the battery got empty, and when I put it on the charger it didn't charge at all. I tried restarting it (on/off home button for 10 sec) nothing happened except it kept giving me the "charge battery" on its screen. I tried with different chargers, still dead! What's weirder is that my sister who has iPhone 4 experienced the same today! No we don't live in the same house!! Does anyone have the same problem?

On belhalf of my fellow volunteers, the answer is, "We'll try our best."
My advice is to try not to treat this like it is a paid service provided by compensated professionals. Ask nicely and one of the nice folks here might take some time out of their weekend to offer advice.

My iPhone 5 keeps turning off saying the battery is dead but then when it's connected to the charger it's says the battery could be anywhere between 40-60%. Any solutions

2 day old iphone 5s turns off at 95% battery life and will not turn back on. HELP

So I had an iphone 4s for two years, the battery started to not last as long, so with my upgrade I got the iphone 5s (greatttt). Anyways I had it for a month then all of a sudden I wasn't getting calls, it took over a minute for me to even get a call to send, then once I was on the call others couldn't hear me well, then it would drop (no problems with service, always happened with full bars). Brought it to Apple store, they told me it was a combination between the phone and my SIM card. They gave me a new one and recommended I go to verizon to get a new SIM card. That same day literally 3 hours later, the phone turned off randomly at 65% battery and WOULD NOT turn back on. I had to go back to the apple store, they restored my phone and almost gave me another new one. However they tested the battery and everything and came to the conclusion it was okay and that I needed to restore the phone and set it up as if I did not already have an iphone (not use icloud to bring EVERYTHING over) So we did that and it started to work, that was two days ago. Over the course of the last two days I have SLOWLY downloaded my previous APPS, however the only way to download those are to do it from the "cloud" because apparently I can't just get them from the app store. Well yesterday I got the blue screen of death, however it came back, I thought nothing except that it was over worked. Tonight it went down to 1%, I left it on the charger until it was at 96%. I had NO APPS open. Went to my calendar and added a event for tomorrow, put my phone down and then ten minutes later looked at it and its turned off. It will not turn on, I tried rebooting pressing both buttons, Ive plugged it back it, switched outlets, switched cords, NOTHING.
Of course I wish I never got the iphone 5s at this point.
What now?
Back to Apple again?

Yep.
Just like cars, you lucked on a lemon.

Hi, thank you very much for your reply. No my phone was never been jailbreak-ed. Never been dropped in water or in any wet surface. Dropped on the floor while texting yes, but it was just a one time incident, last year august i can clearly remember, but after that no more (phone still works fine even after.) restored the phone again earlier, but problem still occured. Will try to go to Apple also to ask and have it checked. Just worried because my phone is already out of warranty. Will keep you posted. Again, thanks. If you have any more advice just let me know. It would mean a lot.
Cheers,

My ipod touch will not turn off and the battery (charged to 100% with trickle charge) is discharging on it's own. Any advice please?

My Ipod touch has not turned off for some time. I reset it. Now, as well, the battery which is charged to 100% and finished with a trickle charge is discharging completely overnight when not in use. Help please, I use this all the time

might want to consider posting in the proper forum. This is the iPhone forum.

Iphone 4 turns off randomly with battery remaining

Hi ,
My iphone 4 has been switching off randomly even when battery is 100% and wont switch back on unless connected to a power source.
This behavior is more prominent when i connect to 3G or when i turn on or turn off the flight mode.
I have already changed my battery and also restore my phone to factory settings with latest ios update but still its not working as before.
I do not remember dropping my phone or it getting in water.
