4s very warm with battery drain

But I have found a solution.... Turn push off, and delete Facebook and MSN live messenger apps!!!

It's just a bug just like every OS they put out, it will probably need iOS 6.1 or something to correct the battery/heating up issue and also the Shotty WIFI/ "unknown" data usage.
back it up, drain your phone to 0%( calibrate ) the battery, then reset and RESTORE from your back up and see if that helps.
edit: also you can't downgrade unless jailbroken..... which could result bad for you. otherwise your stuck with iOS 6

IPad 3 very hot w battery drain when streaming AirPlay!

Why does my iPad 3 get very hot and battery drains very quickly only when streaming with AirPlay?

Just in case anyone else is experiencing the same or similar scenario that I was (see first post), turns out that the Apple Care Geniuses determined that the PMU (Power Management Unit - I think the "U" is for "unit" anyway), was corrupted or not working properly, so too much power was being used for tasks that shouldn't have used up so much power.
They replaced my unit, it may or or may not be a refurbished unit, although it looks new and was manufactured on a later date than the one I brought in.
The Geniuses were very helpful and didn't just turn me away saying to "turn down the brightness or turn off WiFi when not in use" which I do anyway.

IPad mini with retina very slow and battery drains fast

my ipad mini 2 is only ten months old. After getting the iOS 8 currently on ios8.0.2, wifi internet speed is only 25% of the normal speed (compared to what my imac tested), battery drains 1% every 3 minutes or so. All of these after I restored it to factory setting per Apple support suggestion. is there any fix for this soon? why is the issue only affecting some but not all users? Is there anything I can do for my ipad? I have only been using it lighty (have installed like less than ten app's) but this is still very frustrating.

If You Think iOS 7 Feels Slow Here’s How to Speed It Up
http://osxdaily.com/2013/09/23/ios-7-slow-speed-it-up/
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

My iPhone 5 is getting very hot and battery drains quickly.. normal?

I've been having a variety of signal related problems with my iPhone 5 and I'm wondering if anyone can offer any advice. From day 1 I have observed that my phone will have poor signal strength or will switch from 4G or LTE into Edge mode, even if my wife standing right next to me (same network same iphone 5) has better signal. Phone also frequently gets quite hot (to were it's uncomfortable to hold).
I did a long hike last weekend and in the space of 3.5 hours, while doing nothing but listening to music and taking a few photos, the phone was nearly drained (20%). If I tried to take a photo it would simply shut down after pressing the shutter button. I also had no signal (phone was searching), even though other AT&T iphone users around me had signal and were texting, making calls and sending photos (this was from a mountain top so the temps were quite low).
Apple diagnosed the radio in my phone and said it is fine (good attenuation and no dropped calls). They recommended that I wipe the phone and set it up as a new phone versus restoring from a backup (what a pain). I did this and while returning from an outing yesterday I had 3 bars of LTE signal and noticed that with just light browsing the phone got very very warm and the battery was draining quickly. In the space of just an hour the phone plummeted from 75% to 30%.
I'm trying to determine if all of this is "normal" or if I should demand a replacement phone. I have tons of Macs, iPads, iPhones, etc (for both myself and my wife) and I've never seen Apple so reluctant to do a hardware swapout as they were when I was in the store yesterday.

Did you transfer the backup for your 3GS to your iPhone 4S?
Try a reset, which is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release.
If no change after a reset and you transferred the backup for your 3GS to your 4S, try restoring your 4S with iTunes as a new iPhone or not from a backup to see if this makes any difference.

For those with battery drain / wifi issues

Many of you have found a temp fix related to exchange email accounts, this is not for you and I'm glad you have found something that seems to be working.
For those of you with battery oddities, something new to try...
See what security protocol your wireless router is using...is it WEP, WPA, WPA2, etc.
If you are using WEP, try changing to WPA/WPA2 and re-associate your iPhone with your wireless network.
IMPORTANT: Changing this setting on your router will disconnect all of your wireless network devices so only try this if you've tried everything else to this point and your phone is still acting up.
I've spent more hours troubleshooting over the last couple weeks than I care to admit. I noticed that both my routers at the office and at home were still configured using WEP protocol (older/insecure standard). I reconfigured my office network this morning with WPA and updated the configuration on my phone.
Well....................since doing this my 3GS is acting normal again (normal standby drain, not warm, wifi status bar icon not staying on constantly, etc.). So far NOTHING else has worked for me - restore as new, toggling various settings on/off, evaluating certain apps, reset settings/warnings on phone and in iTunes.
I'm curious to know if it makes a difference for any of you as this issue is certainly 'outside' of the phone itself but would make sense as some incremental firmware releases in the past have caused issues when connecting to different wireless networks.
Please report back if you try and after you've had a fair amount of time to evaluate. May just be another shot in the dark but so far it's peaked my curiosity.
Nathan

Thanks once again for your post nateinva. Ultimately it was your suggestion that got me going on the right track, but I had one additional variable...
So, after reading your post I did switch my router to WPA2 (which also necessitated reconfiguring all of my wireless devices) and then once again began testing my phone battery life. Alas, it was the same. It would drain inordinately at home on wifi, but otherwise was normal. Next I read something about router firmware, and indeed mine was a bit outdated, so I updated that to the latest version. Voila, now my battery performs as I would hope. I have several mail accounts, an exchange account and a bunch of other stuff going on. I do have push notification turned off. I now lose about 1% per hour which I find totally acceptable.
Many thanks for the helpful post.

IPod Touch very warm with wifi enabled?

I noticed that with wifi enabled, my iPod Touch gets very warm to the, uh, touch. Also, battery life decreases significantly. Does this not happen for anyone out there? I can't tell if this is a defect or if this should be expected. I wonder if the device can overheat.

WiFi is very demanding on battery life regardless if it is a phone, computer or even the iPod. Be sure to turn it off if you are not expecting to be in a hotspot or don't plan on using it.

What is going on with 6.0.2 exchanged two phones today in store all with battery draining issue problem

Guys, what is going on two phones exchanged in store today all had battery draining problems once phone updated to iOS 6.0.2.
First phone wouldn't last 3 hours usage even in plane mode function.
Second phone bit better battery life 3 hours 15 minutes usage No Apps installed on both phone and location turn off even setup as new phone.

First of all, why did you say yes to Nero Back up before researching what it does with files already on the HDD? When I install Nero, the Back Up is the first thing I disable, it is a nagging pain, there are much better backup programs available. There are several file recovery programs out there to recover deleted files, that is, if that is what happened. Also, if you haven't overwritten the files, so you should be able to find them.

IPhone 4 very hot and battery draining fast

I am having an issue with my IPhone 4 that just started yesterday. It is VERY hot to the touch the screen and the back of the phone. It is also not maintaing a charge. I charged it all night and just taking it off the charger and not using it till I checked the time one time it was down to around 96%. I talked on it for maybe 5 - 10 minutes and only talked and it was down in the 70's. By the time I picked it up again once in the office to check battery power I noticed it was down in the 50's. I am constantly having to charge it and cannot stand to hold it in my hand due to it being so hot. Any advice or ideas?

There is Most likely a Probem with your battery, I would go to the Apple store to see if it can be fixed or replaced.

My 3GS gets very hot and battery drains from 100% to 0% in less than few hours

The problem is really tricky. I kept tracking the problem, the problem persists only in the following case, if cellular data is on with no dataplan registered.If dataplan is activated the problem disappears

I forgot to add, I closed notification center, all push and pull activities and ping.

Resolving battery drain with iOS 5 (not 5.0.1)

Hi
New iPhone user (first iPhone). Unlocked 4s 64Gb. iOS 5 United Kingdom
NOT impressed with battery drain so far and reluctant to "upgrade" to iOS 5.0.1 On standby (most services set to "off") phone has decent life (looking at about a week bofore the battery dies) but as soon as I start using the phone - eg browsing over WiFi, battery drops like a stone (4% in 20 minutes).
I can see lots of folks upgrading to 5.0.1 and doing a full battery drain, full reset & set-up as a new phone and this seems to resolve some issues.
My question is, does this same technique work with iOS 5??
Hopefully 5.0.2 (or whatever it is called when released next week) will sort this out - otherwise the 4s goes back to store for a refund.
Any comments gratefully received.
Cheers
RB

I have also noticed what appears to be decreased battery life after the upgrade, though not this bad. Seems many people are noticing problems.
I noticed and changed a couple of settings that seem to have helped.
- first, fully shut off the phone and then turn it back on - i read online this helped some, immediately after the update.
- in mail settings, for the icloud account (I dont use this but it was configured by default) check the sync settings . it defaults to push, which takes more power. you might want to disable push and set to fetch for this and any other accounts you have, for additional power savings
- in settings, location services, scroll to the bottom and tap system services : All of them are defaulted to on. I turned off location-based iads and setting time zone since i dont need those. (I also opted out of the diagnostics and usage as part of the setup, but it was set to on in this screen - i left it on for the time)
- also in settings -- location settings: check the list of apps and verify that only the ones you want, are enabled
These few settings seem to have improved things

Battery Drains In IPhone 5s In IOS 8.1.1

Hi All ,
I'm Using Apple I Phone 5s White 32gb , Using 2G data That Too Very Rare..
But After Updating To IOS 8.1.1 My Battery Get Drained Superbly
My Phone Stand By Is Only 6Hours And 45 Minutes Only,
Changed Battery From Store Also , No Help ,
Seems There Is A Problem In IOS 8.1.1..
We Need This To Be Fixed In Coming Update , R Else Apple Will Lose A Old Customer ..
Is Any One Having The Same Problem ?

I answered extensively in another forum. Here is my reply. I understand apple released today 8.1.2. I will check if it solves the issue. I have the same problem with battery drain on stand by at 7 hours after doing everything you can read below. Hope it helps
I had the same issue with iphone 5s (32gb) i upgraded as soon as the 8.1.1 came out and i suddenly saw the battery drain like crazy. In mid morning i was down to 40% and in the early afternoon gone. I left it at night running on sleep mode and the battery was drained who knows when. I normally when i have 40-50% I leave it and in the morning i have a few percentage points left....but never nothing !1
My wife is running the same phone on "8.02" and I did not upgrade hers, and no issues with battery drain there. Now she refuses to let me touch her phone in case i upgrade and screw up hers too!.. she is right in not trusting these upgrades. !
I tried all the tips and tricks that you read all over the web to stop drainage...from background refresh, to motion reduce, location, notifications...etc...believe me tried them all.
I also restored the phone a few times to clean start (8.1.1), and then also from my back up in itunes...
Nothing worked. !! My 5s becomes warmer than my wife 5s and there is definitely something running in the background that depletes the battery much faster.
I went to check the battery with my mobile operator and they claimed there is no problem...but go tell the guy fixing screws on iphones that the web is full of reports on battery drain with 8.1.1 .
After much research and waste of time...i managed to find the IPSW for downgrading to "8.1" I did succeed to downgrade and i will be testing in the next few days if all is ok. I will report any results
I learned one lesson....don't trust the iOS "upgrades" until a few weeks and month go by to check what effects they have on the phone !! They sell you a phone for over 700-800 bucks and then you have to waste your time figuring out how to solve their software problems.Who is going to pay for my time?
With a market valuation of over $650 Billion and the stock price over $110, you would expect them to check thoroughly before they release a version to fix one device and screw up the others. I guess Apple & Samsung are almost running a duopoly on Smartphones. Yes, there is competition (HTC, LG, Sony, Nokia..) there but if you want the most advanced model, you need to choose between 2 or 3 suppliers. Once all your data is connected to one Operating System, the switching costs to another platform becomes expensive..cause you need to buy a new phone and a new tablet and move all your data, settings..etc
So for the time being i am stuck with iOS with an iPhone and iPad, and hopefully the downgrade will solve the Battery Drain of 8.1.1
So my recommendation if you have an iPhone 5s : DO NOT UPGRADE TO 8.1.1

IPhone Battery Drain, 7.1.2, I Have A FIX!

Hello everyone! My name is Gabriel Chen and my iPhone has been having trouble with battery draining, and overheating. I'm here to tell you how to fix it. This is completely different from the rest of the posts because I've discovered something interesting and new.
Background (I'm a little long-winded, sorry. Just skip down to "What-to-Do" if you are pretty sure you've had the same problems as me):
I got my iPhone 5s when it first came out. It's battery life was amazing, then the fire nation attacked. Jokes aside, the battery became worthless about a month ago after I updated to 7.1.2. I thought the issue was 7.1.2, but now that I fixed it, I don't think it is. I took my phone into the apple store about a week ago because I was off to college and needed to fix this problem before I left. They ran diagnostics and found kbd and backboard errors. They immediately replaced it. I was happy because I had a brand new phone, but the battery issues came back, and this time even worse. My phone was burning up, even hotter and it even froze sometimes. I then took it to a store near my college–which was difficult because I have no car here–where they did a reset because that's what they always do. I sat there and played with the phone to make sure the problem wasn't there. Turns out it was still there. I love apple genius bar employees, but not all of them are very knowledgeable about the products and how they work. I don't blame them because: updates can always cause new problems, it's probably above their pay-grade to memorize what every single error code means, and they don't necessarily have knowledge that lets them troubleshoot any problems that involve hidden processes that their apple-issued easy-button diagnostic test doesn't tell them about.
I then approached another employee who helped me immensely. He knew something was wrong, which was awesome because most employees do tend to blow you off, so he decided he'd try to help me fix it. He had a lot more knowledge about the phone. This time he found kbd errors again so he replaced it. After that process, he disappeared into the back of the employee's only part of the store. I tried playing around with the phone, and it was clear that the problem persisted. I then went and got help again. This time, the new person who was helping me went to the back, and I waited around for about an hour and a half not knowing what was going on. The whole time, I was wondering where the first guy who helped me disappeared to. For the sake of convenience, the first person who helped me in this paragraph will be Ian, and the second will be Will. Will eventually came back out, this time bringing Ian along with him. Turns out Ian had been doing research for me in the back for the last 1.5 hours and found that the problem probably had to do with iCloud. My phone was draining and overheating due to its attempt to download some sort of data with no success. So each time it failed, it would retry over and over again. This explains the overheating and battery drainage. We deleted some stuff from iCloud and it got a lot better.
The next day though, the problem came back. I was so frustrated so I've been trouble shooting for the past 5 hours. Eventually, after 4 hours, I tried using different iTunes accounts. There was no battery drain when I used these. When I used my original account, there were still problems. So I tried turning off iCloud on my account. Still, I had no luck with it. I eventually tried something else which finally fixed it! My phone now no longer has problems with battery drain and overheating.
What-to-Do
1. Go to Settings —> iCloud —> Delete Account
Don’t worry, as long as you click “keep the stuff” or whatever it says, you won’t lose stuff
2. See if your batter still drains by leaving it on and watching the battery. Touch it and see if it’s heating up. If your battery is draining 1% every 2 minutes, it definitely is still having problems. It’s your own choice, but even if it does drain, I would follow the next step anyways. If it doesn’t drain, the issue definitely had to do with iCloud. Now, log in once again.
3. Make sure all of the iCloud data that you care about is stored some where other than iCloud. For example, make sure your Pages files are on your computer.
4. Go to Settings —> iCloud —> Storage & Backup —> Manage Storage. Then delete the stuff under Documents and Data. I REPEAT, DO NOT DELETE WITHOUT FIRST MAKING SURE THE DATA IS ON YOUR COMPUTER IN SOME SHAPE OR FORM
Why? What is probably happening is that there is probably data that is trying to get onto your phone. This data is failing to do so which is causing an infinite loop of effort and failure which drains your battery and makes your phone work really hard. Apple should code a fail-safe into this to stop the loop, but they haven’t yet.
5. You’re done with this part! For some of you, like me, your phone will stop draining. If so, you’re done! For some of you, it will start draining again! Here’s the part that took me 5 hours to figure out, mostly because I was just frustrated and venting.
6. If you’re still draining, go to Settings —> iTunes and App Store, and turn off SHOW ALL Music and Videos. What this feature does is it will display the purchased items that have not been downloaded, but are on your iTunes account, specifically Music and Videos, within the the corresponding apps. I understand that you probably like this feature and that you’re probably unhappy that I’m telling you to turn it off. This is a glitch or bug that Apple will probably come to fix if it comes to their attention eventually, so don’t worry. When they do fix it, you can turn these back on.
Why? For some reason, the battery drain was being caused either: by the phone failing to fetch data from your iTunes account, pertaining to purchased items such as songs and videos; or by the phone repeatedly fetching the data, instead of just holding it in place.
So, this fixed my phone completely. Please rate me up if that’s even possible. If you’re an Apple dude, I’d love to receive rewards if this was actually useful to you guys (haha, sorry I’m just a little proud of my accomplishment.) If it doesn’t work, try to trouble shoot and figure it out. If you would like clarification, feel free to comment or whatever it’s called. If this doesn't fix it, maybe try getting it replaced in an apple store because that might be the issue.

Thought it had worked but soon found out it had not.
after further days of trying finally, solved it for me Yesterday.
turned off notifications when locked, and bingo, wow.
i have not turned off iCloud but location services are also off.
best thing to do I found was keep checking your usage, settings, general, usage, and flip down to bottom, if the standby and usage are similar there is a problem, if there is a big difference then all is ok. Just keep turning things off and on until the difference is very apparent.
something on my phone was keeping the phone alive even when turned off, and I think this was the phone repeatedly trying to update continually.
to me this is definitely down to the iOS, my wife has exactly same phone and iOS but hers doesn't have any problem and the battery lasts for days.
the guy at the Genius Bar told me to restore the phone via iTunes, not iCloud. This is because iCloud remembers the exact info from your phone and simply reinstates it when you restore, and this includes the iOS too.
when I get home from holidays that's what I'll do, or wait for iOS 8 in few weeks. But I'm so pleased I finally made it work, I was beginning to think ditch the phone and buy Samsung.
anyway anyone out there please try my final solution and let me know if it works for you?

Iphone 4 warm and battery power lost in half a day

HT1688 iphone 4 battery draining out

I believe there were a lot of people who were having issues with battery draining quickly after the iOS 6 upgrade. The latest patch release from Apple was suppose to fix the issue, but for me the issue has become worse. It drains out to almost 74% in 1/2 hr phone call and upto 40% in 2-3 hours with nothing else.
Has anybody else have similar experience? Is Apple releasing another patch soon? I use this phone for my office calls and mails, and constant need to keep it charging is hurting my mobility.
