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.

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.

Enormous battery drain after 3.01 upgrade

guys and gals,
anyone of you experiencing a huge spike in battery drain after upgrading to firmware 3.01? On 3.0 my iphone 3gs had no probs but after my upgrade last night he ran out of juice within a few hours while I was sleeping. This morning I recharged it but an hour later the phone is allready down to 80% and feeling warm. I guess there is something running in the background but I cant figure out what. Turning the phone on/off doesnt seem to do a thing. Any ideas or personal experiences?

I did what you said in your 2nd post, and recharged the battery. after 6 hours, it was the charge was still at 100%!
then I used an app, IM+ Push for a few minutes and had disabled the Push functionality before quitting it. after an hour, I noticed that the battery issue was back. so deleted the said app, and the battery levels returned to normal.
This evening I re-installed the app, disabled the push functionality again and made sure to set my IM account to off before quitting. the problem hasn't re-occurred since then.
hope that this helps someone else who's having the same issue.

Heavy Battery Drain after updating to 8.1 Lumia Cy...

After updating my Lumia 1520 to 8.1 Cyan update, the battery drain is very high. The battery is lasting only for 6 to 7 hours when the data traffic is on (under mixed use of 2G and 3G modes). I have noticed few other users were also experiencing heavy battery drain after the Cyan update.
Will there be an update to fix this battery drain issue?
When the phone was in WP 8 Lumia Black update, battery backup was around 24-30 hrs (when data traffic was on).
What will be the workaround for this?

Yep, my 1520 battery drains like a helicopter that's lost it's rotor after this 8.1 update.
I was just boasting last weekend how awesome the battery life was on this phone, I drove 300mi with the GPS w/navigation, did some tethering to my laptop for work, went overnight..no charging, used lightly all the next day, few pictures, email, browsing, phone calls, and drove 300mi back on GPS/navigation and I still had 38% battery left.
I updated to 8.1 sunday night, and on my normal commute to a customer in another state, which under 8.0 would have drained oh...mabey 4-5%, I was at 62% by the time I got to this customer yesteday.
All I did was make a phone call, that's it. All background stuff is not allowed. location off, cortana off, ...still drains.
Bad bad bad news. I'm not seeing much usefull ness out of 8.1, and considering the battery life and no real new features....just gimmicks if you ask me, I'm not sure I want to stay at 8.1 . I'm trying to give it a chance...battery life is still better than my POS samsung androids I've had in the past, but knowing how good it really can be...and no real features in 8.1 (I was hopeing they'd fix the imap email not allowed to map sent/trash/inbox issue)....eshh...what a mess it seems.

Battery drain after update to 10.2

i noticed high battery drain after i have updated to 10.2. i charged phone to 100% yesterday at 16:00 and now 17h later it is 61%. - i wrote 4 sms'es, 1 short phone call, and that's all. i tried restart few times, checked out if network settings are same as before, nothing helps.
battery application is estimating discharging speed at level of 1% every 24 min. before at the same usage it was at least 50 mins. i heard 10.2 has better battery efficiency, but not for me. anyone has similar experiences after update?

Double check that your Network settings are how you want them as after an upgrade they have a habit of changing.
On my Verizon phone it redefaulted to Global which really burned my battery instead of limiting it to LTE/CDMA, once I changed it back battery life was back (or better) than previously.

Battery drains after upgraded to ios5

battery drains after upgraded to ios5 my iphone4

With iOS 5.0 battery life was terriable. Apple quickly fixed it with 5.01. Now with 5.1 battery life is back to terrible. I could go at least two days without a charge. After the update (and all my patterns and behaviors being the same), I don't even get a full day! Apple needs to fix this! Or allow us to go back to iOS 5.01.

IPad 2 battery drain after iOS 5.0.1 update!!!

iPad 2 battery is draining way too fast after the 5.0.1 update - I've lost over 10% just browsing the apple site over wifi for about 10 minutes - with no other apps running. NOT ACCEPTABLE APPLE!!!
Same issue with my iPhone 4 that went from 62% when I went to bed last night to completely dead this morning - unused!!
Apple - roll 5.0 back out to replace this battery leech. I need to be able to actually USE my products.

Same issue here! I've been reading on my fully-charged iPad and the battery is down to 78%. Never did this before the latest update. Yesterday, iPad quit before my usual evening reading! Any solutions!
I have personally seen the problem and corrected it on numerous models now including the 4S, 4, 3GS and iPad 2s. Corrupt system level settings created by an iOS 5 bug in the original release that caused battery recalibration issues, etc. Just installing the update does not fix the issue in most cases (sometime it initially can be worse). You need to clear out those settings and recalibate the battery. For those still having the "standby battery drain" issue follow the procedure below in order. It does fix the problem in most cases.
Go through these steps to address the battery after updating to iOS 5.0.1:
1. Reset all settings (settings app-> general-> reset)
2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). At this point, Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
3. Turn off system location services timezone and iAd
4. Fully discharge battery (tilll it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!

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 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 after installing IOS7 on Iphone 4

Hi
I have recently installed IOS7 on my IPhone 4.
The battery drains really quickly even when I am not doing anything with the phone. I never had these problem before updating.
Suggestions please???
Thanks

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

Severe battery drain after AT&T sim card replacement.

Up to a point, my wife's original iPhone worked fine. A week ago, it stopped connecting to the AT&T network, and after a call, we found out that someone at a retail store made an error when registering an upgrade to a 3g, and somehow started the process on my wife's account, which killed the sim card. I ran to the local AT&T store and they replaced the sim card for free, and all seemed well.
However, since then, her phone has been suffering from a severe battery drain. I have made sure that wi-fi, bluetooth, and location services are turned off, but it will not last 10 hours in standby mode after a full charge anymore (she makes no calls during the day - just leaves it in her purse on standby). I have tried a full restore of the software/firmware, and she is running the latest 2.02. Is there anyone who can help?

Sorry, no, that's not the issue. First, it's a 1st gen iPhone. Second, as I said in the question, I've already turned off every other unnecessary service on the phone. Basically, it's sitting in her purse on standby during the day, just as a phone, and draining from a full charge to nothing in about 9 hours. The problem only started after getting a new AT&T sim card. I'm wondering if anyone else has heard of this problem.

Nokia Lumia 1520 Overheating & Battery Drain after...

Hello,
I've been experiencing an intermintent problem with my Nokia Lumia 1520 (AT&T, 16GB model) where my phone overheats and the battery drains. The problem started after I upgraded to Windows Phone 8.1 and Lumia Cyan. As of now I haven't figured out a good step by step method to reproduce the problem on demand however I have noted that when this problem occurs and I wake the phone and unlock it the Start screen shows a never ending or unusually long "Loading" message and my phone will overheat and drain the battery. So far the only way to mitigate the problem is by shutting it down manually or performing a "soft" reboot of the phone. Afterwards the problem gets resolved and the phone resumes normal operations after rebooting with the phone returning to a normal temperature and battery drain rate that is consistent with the use it is being given.
Given that I don't know anyone else carrying a Lumia 1520 has anyone seen something similar to the problem I am describing on this post with their Lumia 1520 unit after updating to Windows Phone 8.1?
So far the only big resolution step I've taken is to perform a complete phone reset and not recovering the phone from my back ups, effectively making it a "new" phone in terms of settings and software conditions.
My theory for this problem is that it is software driven as an overheated phone and a stuck "Loading" message instead of the Start screen after unlocking the phone indicates that a software process (either OS or separate Application) may be behind the issue.
Thanks for any assistance on this matter!

Did not work unfortunately... But I have resolved my overheating and battery drain issue...
CORTANA is the culprit and needs to be unpinned from the start screen.
Here is the process if CORTANA is piined already..
1) Unpin CORTANA
2) Go to "Settings.. Applications and open Cortana
3) Turn off Cortana
4) Phone will RESET
5) Go to "Settings.. Applications and open Cortana
6) Turn on CORTANA
DO NOT PIN TO START SCREEN
7) Swipe your start screen over to your applications
8) select CORTANA and allow it to set it self up again.
Now CORTANA is still accessible by the Search icon or from your application menu.
Now your battery.. Before the update my battery was reading "1 day, 14+ hours"
After update After recharge I was getting 14 hours then it would start draining.
After taking CORTANA off the start screen my phone stop getting hot near the camera (Upper left) and after 2 days (Battery cycling) my battery has returned back to reading "1 day, 14+ hours"
My assumption - The matter will be resolved with the Lumia Denim update coming later this qtr.
When that arrives my understanding is CORTANA is off BETA in US. Some additional Firmware tweaking, along with the camera updates and more.. Which "SHOULD" resolve this battery drain & over heating with CORTANA
Per my experience, I believe you're right that Cortana is the culprit for the problem described by the original poster. I unpinned Cortana from my start screen 6 days ago, and so far so good. I have not had a recurrence of that problem. I did not turn Cortana off and then back on again though. I just unpinned it, and that seems to have done the trick.
I'm also hopeful the Windows Phone 8.1.1 and Lumia Denim update will fix this since Cortana will be off Beta in the U.S.

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.
