IOS 5 rapid battery drain (including in sleep mode), springboard crashes: FIX!
OK folks, I resolved all issues in their entirety with the help of a genius bar tech who recognized that I was very technical. WARNING! Sync or backup your phone prior to performing these steps!
First, do a MANUAL download here of the IOS 5 that matches the model of phone you have and save that image to your desktop or some other place on your computer. PUT THE PHONE IN DFU MODE, not recovery mode (google on how to accomplish if you are not familiar). The raeson why you are going to put in DFU mode is so that you will be able to not only get a good copy of IOS 5 installed but to ensure that your firmware is not corrupt, which appeared to be the case with my battery drains and springboard crash issues.
One you are in DFU mode (your screen should be black the whole time, again google), open itunes and it will give you a warning that says that your phone needs to be restored. If you are on a mac, hold down the option key and press RESTORE in iTunes. This will open up a box that will allow you to "locate and select" a file, which will be the IOS 5 image that you manually downloaded before.
Once you do, the iphone will start to restore. After all of the restore cycles have been completed, you will be prompted in iTunes to either setup as a new phone or restore from backup. I USED RESTORE FROM BACKUP so that I could preserve all of my settings. Everything has been working PERFECTLY ever since completing these steps! I will probably go ahead and make a separate thread related to this fix.
I hope this helps! Scott
Their is another thread in here that mentions turning off reporting of Diagnostics data (Settings --> General --> About --> Scroll to the bottom/Diafnostics --> Select Don't send.
Another item to check are you E-mail accounts. If you only have one account in this section then you should be good. If you have multiple and have every feature turned on (Contacts, Calendars, Reminders, etc) then your device could be trying to update to all and timing out which would get it to retry over and over again. I have turned off all the other features for my email accounts with the exception of iCloud and my battery life is looking good.

Battery Drain - iMAC in sleep mode
I hooked up my 16g iPOD Touch to our iMAC, (USB connection) left it alone for a few hours-all set right? Came back to use the Touch and noticed the battery was drained. So I plugged it in again. The indicator shows it is charging, so cable is fine. I am thinking that when the iMAC goes to sleep it stops charging. If so, that bites but I understand. But why would it drain so fast? The Touch was half charged this past test and down to 20% in no time. Nothing running on the Touch.
Don't remember reading anything saying the USB port dies when in login mode or sleep. Usually don't charge it with this MAC, so sorry if this is an old problem. Usually use my MACBook or AC to charge.
Would you agree it's a sleep issue doing the battery drain?
ThanksYes, it because the compute is asleep.

Iphone 4 battery draining while in sleep mode
I have noticed over the past few days that after putting my iphone 4 into *sleep mode* and not using it for several hours that the battery percentage is significantly lower after powering it back up. I first became aware of this after waking up to find my battery was at 50% (8 hours before I went to sleep it was 90%). Just today I was using my phone and the battery was at exactly 85%, I turn it off and an hour later I check the battery at its at 77%!!! I then go for a 45min run (leaving the phone at the house) and coming back I see that it is at 73%.
I don't know if this is a battery issue or a problem with the wifi/3g working when the phone is in sleep mode. My parents both have the 3GS and they do not experience this with their phones.
I have had this phone for 2 weeks and I don't want to have to send it back so please tell me this is a software/settings problem and not with the hardware!!
I haven't changed any settings or downloaded any apps since I got the phone (Except for the free case app). I did however sync my email address with the phone so it may be a problem with that I don't know.
I am also on the original firmware that came with the iPhone 4 I have not updated that yet.ehanger wrote:
I think it had something to do with the signal being weak. I normally keep my phone in the basement where my computer is and often there is only 1 bar or no service at all. In order to make contact with the cell phone tower the phone has to work harder therefore using more battery. I put the phone upstairs in my room last night where the is better AT&T signal and my battery has not dropped off at all.
That could be the issue. Your phone is only getting 1 signal or no service, and is trying to work hard trying to find good service in your basement. Try setting the phone on the first floor where you get good signal and see if that fixes your battery issue,. -

Complete overnight battery drain when in sleep mode
When I close the lid of my Macbook Pro Retina, the battery of my MBP Retina goes down from full to zero overnnight.
Very frustrating because this basically makes that I either have to switch the Macbook off entirely, or that I have to connect it to the power supply.
No weird settings...
- Running 10.8.1
- Energy settings: default
- Power nap is turned off
- Happens with both wifi on / off
Does anyone experience the same issue? Is there a solution?Battery condition is "normal". I have copy/pasted the information below (in Dutch only).

MBA 2013 battery drain quickly during sleep after updated to mavericks
Hi,
After I updated to mavericks this Tuesday, I noticed the battery drains quickly during sleep mode.
Before the system update, everything was ok. Each night after I closed the lid, it went to sleep and the battery only droped less than 5% after sleep of the whole night.
But during the last two nights after system update, it drained more than 50% of the battery during 8-hour sleep. I could feel some heat on its back when I picked it up. I did not change any system setting or installed any new apps.
my MBA: latest 2013 version, 13 inch, haswell i7, 8G ram, 256 SSD.
I liked my mba so much because of the long battery life. But now It was really annoying because I have to charge it very often.
Any ideas how to solve this issue?Hi Hans,
There's another thread going with the same issue as you... check:

Why Does My iPhone 3GS with iOS 4.0.1 Cause Rapid Battery Drain
I upgraded my iPhone 3GS to iOS 4.0.1, and now the battery drains very rapidly---needs to be recharged after a few hours---and gets very warm. Before this, iOS 4.0 was fine (although slightly increased battery drain over 3.1.3).
I use Exchange with push and had no issues before iOS 4.0.1. This may be the culprit now because when I turn off "push," the battery drain appears to be normal (although not extensively tested yet). But, I also have MobileMe, Yahoo!, and Google email accounts set up.
Is this a new problem? Anyone else have this problem? How can this be fixed? Anyone have any ideas?*Reposting this..had done the same thing earlier as well*
This is my observation from past 6 nights;
All 6 nights, charged my iPhone to max and then kept it in sleep/stand by. Not even a single call or mail checked...(11 pm to 6:30 am when my alarm rings)
1st & 2nd Nights, I had flight center, angry birds, twitter, facebook, mail, phone, sms, settings app open in the multi-tasking bar.
Battery drained from 100% to 83%
3rd and 4th nights, i had only twitter, facebook, mail, phone, sms
Battery drained from 100% to 92%
5th and 6th nights, I had nothing open
Battery drained from 100% to 93%
my mail is always in push enable setting to exchange and me account,
location always on, bluetooth always off. 3G off
I thought, the applications on multi tasking bar is actually not draining the battery, but looks like they are...might be a flaw in multi tasking api or may be from developer.
I hope to get an easy way to kill the apps and not let it go to multi tasking bar. -
IOS 4.2.1 + 3G data = hot phone & extremely rapid battery drain
Anyone else having this issue?
Since "upgrading" to iOS 4.2.1 on the weekend, it seems anytime I try to use the phone for data over 3G, it'll heat up like crazy and I can watch the battery drain in front of my eyes.
Everything else works fine including data over WiFi aside from some apps quitting abruptly without any transition effects.
I've reset and just finished Restoring. Less than a minute after I turn off WiFi and use any kind of data, the phone heats up and my battery % actually went down while connected to my Mac Pro.Donovan,
just wanted to share my experience... I too updated to 4.2.1 the other day and running on Rogers network. I noticed that the 3G data seems to be the culprit. Its consistantly downloading data! I can only imagine what Rogers is going through if all iphone 3G's are having this issue :s... I just turned off cellular data and running some tests, later tonight going to try a full restore to see what that will do...
keep you posted. -
Rapid battery drain after Mavericks Install
Hey everyone,
I've spent a lot of time reviewing the existing threads and haven't been able to pinpoint a solution to my issue. I upgraded my late 2008 MacBook Aluminum 2.4 GHZ to Mavericks, and noticed considerable battery drain. I made an appointment at the Apple Store to do a clean install of Mavericks, and this seemed to help but as I installed software required to access internet at school (SafeConnect, AnyConnect VPN, Avast) my battery life has gone down again. Also, the battery drains when the computer is supposed to be in sleep mode. I have a new battery on board (127 cycles, my cycle count has increased a lot due to this battery drain issue). Does anyone have an idea of what could be the offending software and provide me potential alternatives?
Some numbers for reference: With Snow Leopard I have 3.5 hrs of battery life, and after my initial clean install I had 3.5 hrs of battery life (so no improvement, but no worse performance either..). Now I am lucky to make 2 hrs with a full charge.

Bug: Raise to Speak sensor for Siri remains on whenever the screen is active - regardless of Siri Raise to Speak Setting (enabled or disabled).
After updating to iOS 6 (via iTunes - not OTA), I noticed that my battery was taking quite a bit of a hit. Granted I was checking out the new features but aside from a very short call, nothing major in the way of activity.
I had also noticed that Siri sounded quite a bit different with iOS 6 (10A403) than with 5.1.1 (9B206). Not only did the Siri Voice change but also the responses vary between the two iOS versions.
Example: What is the weather like in Alaska?
iOS 5.1.1 response:
Here's the forecast for Juneau, Alaska through Monday
iOS 6.0 response:
Here's the weather for Juneau, AK through Monday (note: Siri does not say "Alaska", instead Siri says 'A-Kay'
With iOS 6, Siri sounds more robotic. After looking at speech rate settings and comparing between the two versions, I could find nothing different. I decided to post a video and this is where the Siri bug became interesting and tied into the battery drain with iOS 6.
Remember with 5.0.1 we saw a hit on battery drain and one of the fixes was a fix to the proximity sensor (http://hottipscentral.com/could-siri-be-hurting-iphone-4s-battery-this-little-li ght-might-mean-something/). Well, it appears this bug is back in iOS 6. When I went to do the video, I noticed that my 4s had a flashing light near the earpiece. It remained on continuously. The only time it would stop flashing was when the phone was locked and the screen inactive. As soon as I hit the lock button to bring the phone out of lock, the sensor would begin to flash again.
Give it a shot, hold up your iPhone to a webcam and see if your result is the same.
Submitting this to Apple via the feedback form. Please do the same if you are seeing the same behavior.
http://www.apple.com/feedback/iphone.htmlI dont believe so Amy. Phone has not sustained any damaging drops nor any liquid spills. Was not an issue before but I figured I'd post as I believe this is a definite bug. I neglected to mention that I have my wife's 4s (5.0.1 build) which I am using as a comparison.
Based on the issues folks are reporting with the ambient light sensor, its either the proximity or the ambient light sensor causing the drain. I've turned auto brightness AND raise to speak both off and the sensor continues to flash as I described in my opening post.
If others can confirm, this will definitely need to be looked at by Apple and fixed.
I just found this - same behavior (posted 7/24/2012 on another forum - source link below).
Hi folks, remember the proximity sensor (always on bug) I reported here in iOS 6 Beta 1 bugs/feedback thread? It continues to happen in beta 3, I reported to Apple and the answer I got from them is that it behaves how it's intended to do
Thing is, when you turn Raise To Speak feature off, and use your webcam (no IR filter) to verify if it turned infrared proximity sensor off, results that it didn't. Since iOS 5 this bug has been present, power cycling, or doing a soft reset solves this issue but this solution does not apply in iOS 6. Don't have an idea on how hard it is on battery draining, but it makes no sense that this sensor stays on forever even when you turn this feature off. Unless it has to do with constantly display brightness adjust feature that we have noticed came with iOS 6 version. Doing some test of this feature (some of you commented about a brightness bug in earlier posts) I noticed that ambient light variations make that display brightness adjust accordingly to brighter or darker ambiences. Previous to iOS 6, the sensor samples the ambient light, and adjusts the brightness; it does this only once--each time you unlock the phone after waking it. Now in iOS 6 you can easily watch how brightness slider adjusts itself when display senses light variations. If you open Passbook app it raises brightness to full (it is supposed to act this way for easy reading of barcodes) but getting out of Passbook app makes that brightness readjusts itself responding to actual ambient light intensity (this adjusting task occurs slowly until brightness slider stops to right level).
I've checked and ambient light sensor and proximity sensor are separate and work differently but if Apple says that an always on proximity sensor in this iOS version is behaving how it is intended to do; all that I could think of is that it has to do with ambient light "sensing"??

Encore WT8 - battery discharging during the sleeping mode
My battery is discharging during the sleeping mode.
If I sleep the tablet with battery fully charged then battery is fully discharged after 14h.
I suppose that must be something wrong with it. I cant find any option to activate functionality to switch off (hibernate) tablet when it is not used in sleeping mode for particular time.
Do you have any solution or advice what I should do to change energy consumption during the sleeping mode?Hi
The system supports connected stand by function which starts working after your tablet goes into sleep mode.
Connected standby function is to provide a constant connectivity while delivering long battery life and at the same time some activities are allowed to run to ensure that the supported connected standby scenarios (for example receiving emails, updating tiles alive with fresh content, downloading/uploading a file from a/to a website and playing music) are functioning properly.
What does this mean?
This means that even if the tablet is set into Sleep Mode, some background processes are still running and this could be the reason why the battery discharges. -
Ios 7 battery drain - using faster than charging now
Anyone else have issues getting a full charge on iPhone 4S after updating to ios 7.0?
It's draining noticable faster - battery drains faster than it charges now so that unless you turn off the screen you end up with less charge than when you docked it. Same goes for regular 30 pin cable to 1Amp wall charger without the dock.
I left mine over night on the iPhone dock and it still only reached 92%
Never had issues on ios 6.
Even with the screen dimmed back to 50% (like I had it set for ios 6),
Battery was at 45% before updated yesterday and even though it was docked and charging during update was at 36% after the update, and kept dropping the longer I had it connected.
Does anyone know for sure if ios 7 is using the A5 cpu differently? maybe running it faster or using more power than on ios 6?
Rebooted my iPhone 4S a few times after updating, nosame issue. Was able to use Safari but unable to download from itunes or app store. They asked or my password, but it said "could not connect to app store, please try again". perhaps due to so many users updating yesterday
Then after opening a few apps (ebay, amazon) battery meter jumped to 100%
I do have DND enabled for notice center. update retained that preference and my screen lock code.
I noticed that even though screen lock timeout was set for 2 mins, it was prompting for code immediately. Had to change to 5 mins, since the 2 minute to lock option has been removed in ios 7.
Thanks,

9800 Torch - Rapid Battery Drain
I've searched a bunch of forums and found that this is an old problem, but this has just started happening on my device within the last 2-3 weeks. I have a Torch 9800 with 6.0.0 Bundle 2647. When i look for an upgrade, the desktop software tells me that i have the latest version (ie..no upgrade available).
My Blackberry 6.0.0 System Software is pulling 100% of the CPU time. I have deleted a few of the apps that i thought might be the culprit, and the problem goes away for a day or two, then boom, BSS 6.0.0 is pulling 100% again, and my battery drains quickly, and the phone acts sluggish, to the point it is almost useless. I am at wits end, and although this appears to have been resolved in an older version of the OS, my OS seems to be up to date.
Any ideas out there?

.g.What OS are you on? On your device, type in a new message MYVER and a space after to see and report back please.
Try a Battery pull please, with the BlackBerry device powered ON, remove the battery 15 seconds and then reinsert the battery to reboot device. This will clear all cache like rebooting a PC. Then try again and see if your problem persists.

Rapid battery drain after turning on iCloud
Is it normal for iCloud to drain my battery so quickly? Since turning on iCloud for Calendars, my battery drained almost completely overnight, and went from 61% down to 36% in about 2 hours doing nothing other than sending one very short (2 words) iMessage. I'd like to use iCloud but keeping my iPhone plugged in constantly is not an option.
Avast is garbage. Uninstall it according to its instructions. Avast's uninstaller will remove it completely.
If your school requires you to use Avast you will just have to tolerate its detrimental effects on your Mac's performance and battery life.

Red Highlight state text looks like garbage
I have a project that my client wants to have his text highlighted in red. The font used is fairly broad and clean (no sarifs) but when in highlight state which is red it looks terrible. Its almost like its not covering the whole white text behind it
