OK EVERYONE HAVING BATTERY ISSUES LISTEN UP

I have been as guilty as evry one here by posting my voodoo solutions to the "battery drain" issue.
But like a broken clock I can be right @ least 2x . I think this is one of them.
By reading every post about battery issues in this forum over the past few weeks and experiencing some issues while I was on vacation last week got me thinking.
Then I went into some other forums- like the iPhone 3G forum here.
You can really learn something.
This battery drain issue has been around since 2.2 . It is apparently a function of the wifi chip getting hot and using lots of battery juice (i am paraphrasing and collapsing many pages of info).
Today I followed a link to someone's blog and followed 1 piece of advise... Turn off AutoBrightness.
Prior to turning off AutoBrightness I was experiencing load values of 0.53 0.48 0.46
after turning AutoBrightness off my load values are 0.13 0.15 and 0.14 - by the way with 3G turned on.
the other advise I can offer is to keep the iPhone cool - not by putting in the freezer (as some suggested) but by cupping in hand and not keeping it in pants pocket.. this may help with wifi reception as well- i will have to test that later.

I noticed while tracking this issue i noticed that my load spiked for no reason. i set out to figure why... last nite thinking i solved the issue i started to turn things back on- eg. skype "stay online".... then i saw in the processes "securityd" come flick off (i took screen shots to compare) after that i turned off skype "stay online" and securityd went away.
i think that something in the "securityd" process is burning batteries and somethings are keeping it alive - like skype- like not closing all safari windows when exiting safari...
i am just guessing and may be wrong-

Anyone having battery issues on iphone4 after using Garmin 2.0 for a while?

Hi mate. I'm afraid I haven't got a solution, but just wanted to say that I am having the exact same problem in my Lexus. I have an iPhone 5 which was paired and working perfectly while running iOS 6 and then iOS 6.0.1. But I was having all sorts of wifi problems (this is my second iPhone 5 as Apple replaced the first one but I've still got the same wifi issues!) so I had hoped 6.0.2 would fix these bugs. But - as you've found too - it's broken by Bluetooth connection to my car!
I too had tried the same things as you : deleting the profiles etc. but it just won't pair!
If anyone has a solution please help!!

I notice a lot of you started having battery issues after updating to iOS 6....

I'm not saying this could be the reason but I'm about 98% sure it has something to do with it. I have an iPhone 4S and when I first got it, I remember the display was very very bright... i would set it on low and it was still pretty bright. Battery consumption was horrible, I could literally sit there stare at the screen and see the battery percentage drop. Then when some kind of update was released about a month later iOS 4.XX something along the lines... that suppose to fix the issue. I updated my phone and it was fixed. However, it was fixed because my phone got more dimmed.. i could max out the brightness and it was still no where near the brightness of before. And this cause my battery life to be better. However after I updated to iOS 6 the brightness came back, and my battery is rapidly decreasing like it did before. So i'm guessing this had something to do with the battery issues. I'm hope this will help you all. to make your battery last longer, dim your phone, better for your eyes too

I, on the other hand, had no brightness issues on the 4S after upgrading to iOS 6, and no change in (good) battery life. If could be something else, an app or background process that is less efficient with iOS 6? Could be anything.

Temp warning, now having battery issues

I was outside Monday using my iphone 3G S in the sun...the outside temp was around 85. My phone overheated and caused the temp warning screen to come up. I put it in the shade and didn't use it for a while so it could cool down. I plugged it into the charger when I went to bed as I usually do. The next morning I had a dead battery signal (red battery strength and lightening bolt below) the phone would not respond. I moved it to a different outlet and it came on and showed full battery strength. Every time the phone went to sleep it would lock up and show dead battery again. I could not wake it with the button on top and had to do a restart several times before it would even turn on. Twice I couldn't get it to come on until I hooked it up to my computer. I'm having the same issues again today. I NEED my phone to work! It is one of my main business tools!

tp those posting on this i have come across the same problem as many out there over te last few days as my company IT guy came to set up my outlook on the phone. prior to this it was good to go and happy it all worked well. however obver the last two days after constant charging the phone ran out after mere hours! i deleted all the apps incase there was a virus and from other sin this forum i have gathered the techniques to solve this.
turn off 3g if you do not have ths function in your country (i am using mine in china as i am bsed here for some of my work time) they dont have 3g and this will cause battery drain
this is closely linked with email settings. fomr others in these forums suggest turn off all push mail functions on your phone if you dont have 3g or edge. my phone was trying constantly to conect to the internet to download emails but failing.
i did these two simple steps and have had the phone on all day and am still at way over 80% battery life!
i guess iphone havent published an offical not on the web about this issue as they intend 3g iphones to be used by 3g subscribers in those countries only.
i also assume the intention is you buy an 3gs as you have 3g so wouldnt need to worry about turning it off.
i hope this helps as i am a big fan of this machine and would hate to see others suffer as i did, had improtant calls to wait for and the phone got so hot it wouldnt recieve cals!

IF you are having Battery issues, please read. . .

One thing that people NEED to understand about Batteries, is that they need to be Conditioned when they are New! Meaning, that the first few times, they need to be DRAINED completly until the iPod shuts down(Regardless what the meter says), fully charge it again, and then drain completly a few times!! Don't rely on the meter!! It's a Guess, for the Video's/movies/pictures anyways. Here's WHY the meter is so 'flaky' at times: When you are listening to mp3's ONLY, the meter will read pretty accurate, cause it's a low drain on the battery. When you play movies/video's/pictures, it's a HUGE drain on the batteries at the time, so the meter reflects the CURRENT draw, and that's why it seems LOWER then it ACTUALLY is. So, let's say that you start out with a Fresh charge. You start watching a 20 minute video. At the end, it shows less than a quarter of battery left, and you are like ***?! It's NORMAL!! Turn it off for a few, and turn it back on. It should be somewhat accurate of the actual battery stength! Don't rely on the meter 100%. It's a Reference, especially when you are watching videos/movies/pictures. With MP3's I have found that it's pretty accurate. But, I have found when the battery meter says it's dead, it'll last for a few more minutes..
One thing.. IF you have a New iPod, Condition the battery FIRST, before relying on the Battery Meter! !
I hope this thread helps some people out that are asking "Why is my battery only lasting XX amout of time?"

True about them 'Thinking' about NOT having to condition the Lithium ION batteries, but when I received my new laptop battery, it stated that I should condition the battery a few times. I noticed a decresed battery life, AND not-so-accurate battery meter the first few times with it. Since I have conditioned the battery a few times, it lasts much longer, and the meter is more accurate.. So, I honestly don't know why, but it worked..
I'm NOT claiming to be a battery expert, but what I have read, and have done for me. So, I wish the best of luck to you guys!! I know it's HARMFUL for you to keep draining the battery EVERY time, but I don't think it's bad for you to do it a few times when it's new..
Just my $0.02 worth..

Hi everyone! Battery issues!

i just bought a mbp 15" 8GB last week online from apple ( 4/13/2011) BTW- i just switched from being a pc user to mac and am in looove with macs now! My issue is that my mac has been plugged in all day. i unplugged it to watch a 2 1/2 hr net flix movie (started at 98% battery) by the time i finished the movie and replied to a few emails, it's now on reserve??
Apple advertises that this mbp gives 10 hrs of battery life. Did I get a lemon? Is anyone else having this problem?
thanks in advance for any help

MacBook Pro

I'm having battery issues with macbook pro

I've tried calibrating my battery on my fairly new (3 months old) macbook pro, but it has not resolved the issue. Whenever i connect the charger to my mac it momentarily lights up green for a few seconds and then goes to amber which obviously means it's charging. My issue is it never turns green after letting it charge for an hour or two. I've also noticed at the top, my battery icon the percentage time just when it's about fully charged rather than the percentage time go down it goes up. Please help

My issue is it never turns green after letting it charge for an hour or two.
It may not be fully charged after an hour or two, depending on how far down it was drained beforehand. A full charge can take several hours.
I've also noticed at the top, my battery icon the percentage time just when it's about fully charged rather than the percentage time go down it goes up.
If I'm understanding this garbled sentence correctly, you mean that the time estimate until full charge is achieved sometimes increases near the end. This is to be expected, because the rate of charging slows down at the end.

TO EVERYONE HAVING NETWORK ISSUES: Possible Bug Identified. Need Testers.

Please do the following and report back if it solves your issue.
sudo ifconfig en1 mtu 1400
... or if you're on Ethernet (en0), go to System Preferences / Network / Ethernet / Advanced / Ethernet and set the configuration on Manual. Set the MTU to 1400.
This isn't the most optimal value, but it's low enough to account for the issues I've tested.
What seems to be happening is that the MSS value being sent by OS X is not accounting for the additional bytes required for the TCP optimizations that were added (timestamps in particular). So servers are probably trying to send larger packets than they should back to the client (You most likely).

It doesn't matter what you're using (Ethernet or Airport). They both default to an MTU of 1500 and therefore an MSS of 1460, which is too large for PPPoE users with timestamps enabled.
So reducing the MTU (temporarily - again, this is not a fix, it's a setting to prove that this is the issue) to 1400 now reduces the MSS to 1360 which is plenty small unless you've got a lot of tunnels in path which most people won't.
If we can confirm this is related to the problem that most people are having then we'll have a very solid case for what the bug is.

Anyone else having battery issues since updating to iOS 7?

After updating my iPhone 4S to iOS7, I noticed a horrible drain on my battery! From 100% to 62% in less than two hours... I have tried shutting off Bluetooth and even disabling refreshing background apps, and have my screen brightness set at less than 45% but it is still draining fast... Is anyone else having this problem and does anyone have any idea why?

Okay it seems I was right.
After I originaly posted here I unplugged my phone and let it drain to about 30% before charging it back up to full. I went home and my 5 year old son and I played on it, including an pretty memory intensive human anatomy app for kids -- sometimges plugged in, sometimes not. Used it A LOT last night, playing with settings, cheking out the new auto update feature, notifications, etc. I didn't end up turning any of the new features off in settings, and even enabled a few new features. Then, as usual, I plugged it in when I went to bed and let it run a clock/alarm program (Rise) all night.
This morning I drove to work (about 20 minutes) with turn-by-turn navigation running and a podcast playing in the background -- not plugged in to power. When I got to work the battery showed 98%. Leaving the phone unplugged, I have been playing that video podast for half an hour -- with a pause for a phone call set up by Siri -- and battery is currently showing 93%.
I think it's going to be okay. Everybody breathe.

Kelly speca is having battery issues with new iPhone 6 plus.

Hi this is Kelly Speca,
I have a serious issue with my iPhone 6 plus. While watching movies or rather playing some basic games,the battery drains out very fast. It is a s fast as that I have to charge the phone almost 2 times a day...Also the phone touch screen becomes unbarely hot.So can anyone help me with some suggestions..
Thanks,
Kelly Speca.

It may be worth your while to engage with Apple in a chat online or go to an Apple store. It seems as if you have some hardware issues that need to be sorted out
But here is a test I would do to check the battery drain:
1. Do this at night before going to bed
2. use app switcher and close all apps
3. Go into settings - cellular and turn cellular data off
4. Put phone in airplane mode
5. Charge phone to 100%
6. Then un hook it from the charger and let it sit overnight and see what the battery percentage is, in the morning
This will tell you if the battery itself is not performing up to par......

I'm having battery issues after updating to OS 10.9.2. Anyone else?

I noticed that my 13 inch late-2011 MacBook Pro has seen a significant decrease in battery life after updating to OS 10.9.2. For example, I will turn off my wifi and just watch DVD's and the battery life isn't any where near what it used to be. It's only a few hours! This is awful. My brightness settings are down and I'm not connecting anything into the USB ports and I am not using wifi. Any ideas or anyone else experiencing similiar issues?
Thank you!

I would suggest taking the computer to an Apple Store or Authorized Apple Service Provider to have your computer checked. I can say that based on your numbers your battery is about to reach the end of its usable life (which is about 1000 cycles), however that should still allow some time of computer use after taking the MagSafe adapter out of the computer. Ask the rep to run a complete hardware test on your computer. You can also save some time by running the Apple Hardware Test yourself and noting down any error codes that may appear during the course of the test and giving them to the repair representative.
You can learn more about the Apple Hardware Test here:

Hope this helps!

I'm unable to get Yahoo email to work on my new iPhone 4. Get message that Server Unavailable try again later. Is everyone having this issue?

Does anyone know why Yahoo is having problems with email on the iPhone 4? I just upgraded yesterday from a 3G and it was working then but has yet to work on the 4.

I'm having the same problem with hotmail .. it worked this afternoon now I get 'not connected to internet', 'could not activate cellular data network' ..... email and safari are not working

Am I the only one having significant issues with battery life on the iphone5?

I purchased an iPhone5 at the end of June 2013. Ever since I downloaded iOS7 I have been having battery issues. This past Friday the issues got worse. On Monday night (1/6/14) my phone unexpectedly shut off 22 times according to an Apple rep. My phone was replaced yesterday and I'm still having significant issues. My battery drops somewhere between 2 and 5% if I simply unlock the phone. I went over every possible setting with an Apple rep tonight to make sure my settings are making my phone as efficient as possible. All apple reps are telling me is that I can replace the phone yet again or I can do ANOTHER factory reset. I refuse to deal with this company because it's been 3 days and 14 hours. Has anyone experienced this with their iPhone5 because if I have to call another apple rep I'm gonna flip out.

So now 12 days later and another replacement I'm still having issues and apple still isn't helping. My phone has started shutting off unexpectedly again today. Does anyone have any suggestions on where to go from here?

Advice for ppl that have Battery Issues

Hi everyone,
I been using my Lumia 800 since December and recenty updated it to the latest firmware version.
I charge my Lumia via USB every night and it lasts me for a good 13+ hours with lite/medium usage. Usage such as checking Facebook/Twitter updates, Fuse for RSS feeds, Outlook/personal e-mails, messaging, playing and download music and light gaming about 15 minutes.
I usually leave my Wifi turned Of. Only in places I turn it on are at Wifi hotspots which I have passwords to.
After recieving the latest firmware I hard resetted my phone and started from scratch no complaints. If you having battery issues after the firmware update this is what I recommend
1. Perform a hard reset on your phone
2. Charge the phone to max using USB. I heard the faster the phone charges the faster the battery will die so I charge my phone nice and slow via USB every night
3. Run the basic applications and see how long your battery lasts you for. So run your phone with the stock apps for a day and see how good it lasts you and then slowly start adding apps. Maybe theres an app in the background messing up your battery life etc
Give this a try and see if it improves your day to day experience I can go through a day with ligjht/medium usage but usually I charge it at night. From what I understand this update focuses on Idle time so as long as your phone is in idle it shouldn't eat alot of battery.
Let me know what you guys think and if this helped you guys with your battery problems. If you guys have any questions you can hit me up on twitter @based_graham

you could choose to back it up if you want. The important thing is that you do not restore after u formated your iPhone to your backups.
Go here for learning how to disable iTunes backup:
http://iphonefreakz.com/2008/07/27/windows-users-disable-itunes-backup-for-faste r-sync/
for now u can choose to cancel (x) backup. sync your photos and videos and contact info and etc.
one more point, you must reset to erase all data and content. restore alone will not fully erase your phone.
