Iphone 3GS shuts down now after Battery goes to 50%(On 5.0.1) Help

My Phone will now shut down after battery life goes to around 50%, I can get back on but then it goes off again..
New since I upgraded to 5.0.1....
Any ideas ???

I have exactly the same issue with iPhone 4 iOS 4.3.3 getting empty battery shutdowns at 20% then at more than 20 % seems to be poor calibration but I don't know how to reach 0% if it keeps shutting at 20% anyways charging to 100% then restoring appears to solve the problem but it's only a matter of time then the problem comes back ... Any ideas

Why does my iphone 3gs shut down when battery gets to 80%? have installed new battery and nothing changes?

Why does my iphone 3gs shut down when battery shows 80%. a couple of months ago is shut down at 60% but has continually gotten worse. this was before 5.0. i took it to a repair man and he tried a used battery, a new battery, and the original battery. nothing helped. 5.01 didnt help either. What is my problem?

Fully discharge the battery (till it shuts down and won't turn on) and then fully recharge it (100%). This will recalibrate the battery meter. You may need to do this a few times.

My iphone 4 shuts down now and then battery is charged

since one week, my Iphone 4 shuts down now and then (randomly). then I have to push the top button to restart (apple sign) and after 1-2 minutes, its running again with unlocked sim. Can anyone tell me how to fix this. (my iphone 4 is 4 years old and i'm attached to it..) kind regards

Hi Asem,
From your post I see that your iPhone 4 is unexpectedly shutting down while you're using it. To help resolve this issue please follow the directions outlined below.
If your iOS device restarts, displays the Apple logo, or powers off while you're using it
You might see this unexpected behavior on your iPhone, iPad, or iPod touch if you have an older version of iOS. These steps can help.
Make sure that your device is up to date and your apps are up to date. If you still see this issue after updating, contact Apple Support.
Learn what to do if your device won't start up past Apple logo or doesn't respond.
If your iOS device restarts, displays the Apple logo, or powers off while you're using it - Apple Support
Have a good one,

Iphone 3gs shuts down & reboots on its own.

The 2 yr old iphone 3gs shuts down on its own and the silver apple icon pops up ~ the phone boots itself up. This has been happening more frequently, since Dec 2010. I could be on the internet, or using any app and it does this. A couple times I had to simutaneously hold down the power and home buttons to turn on the phone, and, or, unfreeze the phone. I always charge my phone, and regularly sync it with the latest upgrade(s). What is going on?

I had this, but I have now rectified the issue. It's an app?
I de-selected all my apps and just left the standard ones on.
I did a full restore from backup but did not sync any apps.
Problem solved, no more dropped calls. No more apple logo for no reason.
I am slowly re-adding my apps, 1 or 2 at a time, I have over 150 so it may take a while but so far I have reloaded about 10 of my most used ones and still everything fine. I will find the one that caused the problem eventually!!
Happy bunny again though, as I have a phone that can actually make a call for more than 5 minutes!!

Why does my iphone 3gs screen go white after it goes "to sleep" for the first time after turning it on?

Why does my iphone 3gs screen go white after it goes "to sleep" for the first time after turning it on?
The screen isn't broken because it works after i turn the device off and back on, but after it goes black once, it's only white again.
But it takes the touches although it's only white, because I can answer my phone when I slide my finger on the bottom of the screen, eventhough there in not the button to see.
This is so weird. I have already done everything I can think of that might help. But I cannot think of anything that might be causing it, because nothing has happened to the device.

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?

IPhone 3GS shutting down randomly...

Hi,
I was wondering if someone has experienced an issue where an iPhone 3GS shuts down randomly. The issue started tonight just a few minutes ago, the only thing I installed yesterday was iOS 5.0.1. Personally, I don't know what has happened, I do know that my brother has downloaded some songs using the Download Lite App from the App Store. Curiously the issue started occuring after the downloaded one song using that app, but other than that I can't find a problem indicator.

I also having the same issue with my iPhone 3GS with iOS 5.0.1, except most the day went by okay for me until near the end of the day. Perhaps I don't use my iPhone as frequently as you guys are but when I really on to something on it, it just shuts down like a Window virus. (hehe)
Also find some more details on my similar post:

Thanks for sharing comments/problems guys. It really means a lot.

my iphone 4s shut down quickly after charging why?

Most likely due to faulty battery. Make Genius reservation and take iPhone to Apple Store for free quick battery diagnostic testing.

My 3gs shuts down spontaneously after 5 minutes

My iPhone 3GS started to act up recently.
It just shuts down spontaneously after about 5 minutes irregardless of what I am doing with it.
It is not a jail-break phone.
Can someone please help?

My iPhone is doing the same. Went to apple they showed me how to click home twice then hold the most bottom left icon, then there will be a row of icons across the bottom screen these are all the apps running at the same time. Try closing them all except what you need. Because this multitasks it could be crashing.
However...
Also could be the lithium-ion battery/controller. Because lithium batteries cannot be allowed to be discharged completely they have (I suspect) a built in controlling device. If this device or the battery does not operate according to design your phone will shut down so the battery does not over discharge. Lithium-ion batteries should never be exposed to extreme heat either.
Because I feel that my problem is my battery I am taking it back and insisting replacement

IPhone 5 shuts down with the battery at 40%

I'm having issues with my iPhone 5. It regularly shuts down with the battery being far from 0%. When I took it to the apple store, a "genius" said that the battery is fine and restored the phone to the factory settings. I set it up as new without touching the backup (with iOS 8), but the iPhone keeps shutting down with a half charged battery. If anythings, the problem only became worse with iOS 8.1. I would appreciate any suggestions on how to fix it.
The iPhone is out of the warranty and is not eligible for battery replacement. Another issue I have is that the home button often responds with a delay, but I don't know if it's related to the main problem.
Thanks

Here's the battery info from iBackupBot:
CycleCount: 368
DesignCapacity: 1430
FullChargeCapacity: 1200

Iphone 4s shuts down when it battery life gets to about 17%. prior to IOS 7 it would shut down at about 1%. What's up? (Oh, when I plug in recharge, the battery indicates it's at 17% or so. So, I'm not referring to battery drain).

My iPhone 4s shuts down when battery indicater reaches about 17%. When I recharge, indicater shows about 17%, so apparently this isn't fast battery drain. Oh, this happens since IOS7.

See if your phone is one that Apple has noted as requiring a replacement battery: https://www.apple.com/support/iphone5-battery/

My IPhone 3GS shuts down

My IPhone 3GS shuts of while making a call & when the wifi is on. I need to connect it to power to put it on. What's to be done? Thanks, E. Frank

try a reset, hold down the home/power button together for 10 to 15 secs or until you see the apple logo and then release. Then wait for you phone to boot back up.

My iPhone automatically shuts down when the battery reaches 50%. How can I resolve it?

IPhone 3GS Shuts Down When I Get To 20% Battery - Battery Doesn't Last

So like everyone now, I'm experiencing battery issues on the 3GS after upgrading to 4.3. My phone can barely get through a 5 hour day at school & it's dead before I even get to work at night. I'm constantly having to keep my phone plugged in to the external battery I bought. My 3GS also automatically shuts down as soon as my phone reaches 20% battery. This never happened before iOS 4.3. Used to be the phone shut off at 2% battery, not 20%. Anybody else experiencing this? I hope this gets fixed in an upcoming update soon.

I have exactly the same issue with iPhone 4 iOS 4.3.3 getting empty battery shutdowns at 20% then at more than 20 % seems to be poor calibration but I don't know how to reach 0% if it keeps shutting at 20% anyways charging to 100% then restoring appears to solve the problem but it's only a matter of time then the problem comes back ...

Iphone 3gs shut down and now wont switch on help!!

My 18 month old iPhone 3GS won't turn on. I had the screen replaced in an Apple Store on Tuesday, and was advised to reset it, as a new phone, because it would cut off mid conversation.Which I did Tuesday, too, losing everything, because the advise was NOT to use the backup. (All the software was upto date as I checked before handing it over in Store).
This morning It won't turn on, and I know the battery isnt dead. I've tried simultaneously holding the on/off and home button for minutes at a time, it won't connect to iTunes, nor will it register in the charger. I've even loaded iTunes on to my husbands computer, and the phone is still not registering!
I've trawled the internet for advice and tried every suggestion I've found, but it's still just blank.
I need my phone, I can't get to the Apple Store til next week. Was my £80 new screen wasted money?
Here's hoping someone can help me.....thanks in advance
Niki

I'm guessing whoever installed your screen didn't install it properly. I'd take it back to them.
You could try Recovery Mode... http://support.apple.com/kb/HT1808
