Battery drain after 2.2 update (Exchange Active Sync users or those who use a calendar on the phone)

A lot of folks are having "issues" with battery life after the over the air (OTA) update and there has been much speculation as to the cause. My frustrattion level increased with each new post I read that did not reveal a resolution. The back and forth banter about FTC complaints (that was an interesting escape from the battery problem but not very helpful), new apps running from startup (I don't like 'em either), Linux really working better with all these programs running (don't really care as long as the battery level isn't drained after an hour of just sitting on the counter) just made matters worse.
I would like to share with you my experience and hope that it helps some of you who have taken the time to read my post. First, let me say that the cause is not due the the "bloatware" applications that were installed during the OTA update.
Secondly, the primary purpose of my handheld is for voice calls but running close behind is my need for immediate email, contacts and calendar information (which is configured through Exchange Active Sync). If you are not using your phone with Active Sync or updating a remote calendar like Google), you can stop reading this post.
I noticed that the yin/yang (sync) icon at the top of my screen kept popping up more than usual after the update. Looking through the items I have set to sync (Menu -> Settings -> Accounts & Sync), I reviewed all the things I have set and disabled the sync settings for the things I did not want. After disabling the "Backup Assistant", "Google", "News", "Stocks" and "Weather", I thought for sure the issue would be resolved. Not yet. When those adjustments didn't change the frequency of the sync, I decided to look at the Exchange Active Sync and to my surprise, the culprit was revealed - the calendar was stuck in a sync loop (syncing over and over). I disabled the "Sync Calendar" feature and the phone stopped it's maddening attempt to refresh the calendar.
I let the phone cool off and thought that I could get by with manually toggling the option to sync the calendar but I couldn't accept that was the only way this thing would work. I removed the Exchange Active Sync account and created a new one. After the new account was verified, it attempted to sync mail, contacts and calendar but this time, there was a error that occured during the calendar sync. Instead of repeatedly attempting to re-sync, an error message that stated "Client/Server conversion error". At this point, the calendar sync loop was no longer a problem (wasnt' draining the battery) but now my calendar wouldn't sync at all.
To fix it, I cleared the data in the Calendar applications (Menu -> Settings -> Applications -> Manage applications -> All [tab at the top]). Scroll down the list and open each of the Calendar items and click the "Clear Data" button.
(Credit goes to "Brenny" at AndroidForums.com for the post that explains how to clear the Calendar Data)
It seems that adjustments made to events before the update were kept in the phones local storage. After the update, the calendar data in the phone's cache was not matching my remote calendar and appears to have been the cause for my battery drain. After performing these steps, everything is back to normal. Good luck!

Super frustrating, I know. Do you use Exchange Active Sync?
If so, you might be having the same issue that I've explained. Since making the adjustments (clearing the data from the Active Sync components like mail, contacts and calendar), my battery life is back to normal.
Try clearing the data (see first post in this thread) and let me know what happens.

Severe battery drain after last verizon update

After the last update for my phone I have been experiencing around 10% battery drain an hour with moderate to low usage. I have already done 2 factory resets and formatting my SD card. I have disabled GPS, WIFI, Global access, Google now and everything else that i can find that could cause a drain. I have even gone and disabled/uninstalled all apps that I don't use. That didn't fix anything. I started to suspect that my battery was bad. Ordered a new from Samsung and charged it all night on there spare battery charger before using it. It actually seems to be draining even faster, after 45 minutes I was already at 88%. During that period I sent about a dozen texts and checked email and the weather. So I don't believe its the battery. Any suggestions to help resolve this will be greatly appreciated.

likegod04, thank for posting. Are you still having battery issues? If so, then next option will be to replace the device. How long have you had it? Is there any physical or water damaged done to the phone?^SP

Samsung GS3 Battery Drain after 4.3 update

Greetings,
If you aren't already aware, there is a serious flaw in the most recent update to the Samsung Galaxy S3. The 4.3 update causes a serious issue with battery drain, screen responsiveness and some apps not functioning properly. If you search for this issue you’ll find it’s not carrier specific. This update was originally delayed due to battery drain and other issues yet here we are with a December roll out and the same issues. I called Verizon today and they are aware of this issue but have not received a plethora of calls (yet) according to the rep I spoke to.
Bottom line, if you have not installed the update, DO NOT. Wait until a fix has been implemented. I’m lucky if I get 10 hours of light use when I could go 24 hours prior to the update. If I make a few phone calls and use any apps I am forced to charge my phone within a few hours. This is by far the worst issue I’ve ever had with this phone. Up until now everything has been quite solid. If you are having this issue please call Verizon so this can be escalated. I’m hoping a fix will be pushed out in the next couple of months or sooner. My Galaxy S3 is not rooted as I really never found a huge need to do so. Hopefully this issue will not push me in that direction. All I want is a phone that works as expected. You can try using the Deep Sleep Battery Saver app which has a free version for the time being.
May the force be with you, always…..

I noticed in December after an update that my phone was having significant battery drain issues. I also had issues with the phone suddenly shutting off when the battery wasn't even all the way ran down, but would not turn on until it was plugged in again.
Now today I received another update. This one I had no choice but to receive. The battery is once again WORSE. I hate the new look on this update. Features I used that were standard on the phone (such as T9 word) have disappeared and forced me to use an app to replace it (again, HATE that). I realize the updates are essential to have the latest technology but I DO NOT understand why features disappear. This is so irritating I'm about to opt out of even having a smartphone all together. I got this phone when it was on the market 2 weeks. Its "old" and my contract isnt even near up! Its ridiculous at best.

Battery Drain after iOS 6 Update on my iPhone 3GS -16G

My iPhone 3GS 16G on iOS 6 after update.
2 - 3 hours it's flat & thats from a full 100% (over night) charged phone with no use
& then keeps switching on & off for 20mins or so in charge mode after it's been pluged in to the charger.
Never had a problem on the old iOS 5.1.1 got up to 2 Days on standby .
Never had a problem with my phone ever until the new iOS 6 install.
... GET IT SORTED APPLE PLEASE A.S.A.P

Got onto Apple Teckies yesterday & spent about 1.5 hours on the phone with a very helpfull bloke
that went through everything.
At this stage my phone has been reinstalled with iOS 6 as a New Phone (Like a test mode) so NONE
of my APP's or Settings only my Contacts from iCloud (As a New phone would come out of the box).
... From the time we finished uploading the iOS 6 softwear untill now my phone has only used 40%
battery so it's looking good.
If this works I then have to conect my phone with my iTunes & Reinstall from my Back Up to get all
My App's & Settings back.
... Then we will see if it has worked.
... Will let you all know what happens in the next 48 Hours.

Battery drain after IOS 6 update

I and my 3 family members and two fellow employees have all noticed that since upgrading to IOS 6 on our cellphones we have had the following issues;
1. Massive battery drain
2. Battery heat-up during recharge with the phone on but not being used.
3. Lost data
With the phone on and not being used - the charge level drops much faster. I used to go the whole day on one charge and recharge at 10 pm with 30 - 40% of the charge left. Since the IOS 6 upgrade I'm recharging at 4pm with a 10% charge remaining on the phone .
Also - recharging the phone while it is on (but not in use) causes noticible battery heat-up.
Again - this was not the case for any of the 6 of us prior to downloading IOS 6
My conclusion is that there are aspects of this new operating system that use a lot more battery juice than the previous IOS 5.1.1
This significantly increased demand on the battery is showing up as much less operating time and battery heat-up during recharging.
Anybody else experiencing these issues ?

E6 battery drain after microsoft apps update

just two days ago i updated with microsoft apps in my e6 belle. Now the battery doesn't last even a day. I went to installations in settings and tried to uninstall microsoft apps, but a pop up says 'file cannot be deleted'. How do I uninstall microsoft apps from E6 belle? Seriously upset with nokia. at this rate i will start a facebook page telling people to switch to android, with nokia anyway already suffering from the osborne effect. Really upset. Just tell me how to remove this slow and useless microsoft apps from my supposedly good business phone e6? I was much happier using the faster and more user friendly quickoffice.
Problem: need to uninstall microsoft apps (word, onenote) from E6 belle.

@deb52001
Can only suggest that you have a look at this resource:http://digipassion.com/2012/06/uninstall-microsoft-apps-from-symbian3-belle-phones.html
Since QuickOffice not currently compatible you might like to look at Picsel SmartOffice as an alternative..

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.

Iphone4s battery drains while charging on updating to ISO 8.1

hi, i was trying to look for the "ENERGY MANAGER" but i couldn't find it. also i searched it by typing but it's not showing, do you thing it has been deleted when the 8.1 was installed?

This setting is designed to help conserve the health of your battery if you tend to use your laptop while plugged in. It's not good for the battery to be held at 100% for long periods of time, so instead this setting stops chargins when the battery reaches 60% to prevent battery damage.

Exchange active sync not requesting advanced setup details

hi - we have exchange 2010 with active sync 14.1 we have many types mobile devices connected using active sync including iphone and android. when we previously added any account onto a phone we always had to add the advanced setup manually during
the setup i.e. mail server and domain. now these details are added automatically after adding email and password. This seems less secure and i need to find how to stop this.
Thanks

Hi ,
This is normal behavior in exchange because of autodiscover feature and it is making up the things easier during new account configuration on mobile devices.
After giving up the user name and password ,autodiscover is the feature which will bring up the remaining settings that you mentioned .
We will discuss in terms of security view .
1.User's password would be confidential .
However in worst cases someone might know about anyone's password and email address then on such case there would be chance to configure that particular account in any of the mobile devices.
We can control the above scenario too.
In exchange Active sync organisation settings we have an option to set the DefaultAccessLevel to quarantine for the devices.So that administrator can decide to allow or block the active sync device which is trying to connect to exchange.
Reference Link : http://exchangeserverpro.com/preventing-new-activesync-device-types-from-connecting-to-exchange-server-2010/
Note : If your existing exchange organisation is having active sync devices configured in use then before changing the "Defaultaccesslevel" to quarantine we need to make sure existing active sync device ID'S are added to the corresponding mailboxes

Exchange active sync not loading emails?

Hi I am currently using a Samsung Note 2 and i've added my Company email account successfully using Microsoft Active Sync options in Email settings.
however when i go to look at emails, the inbox just stays on "loading..." indefinitely and does nothing.
Does anyone have any ideas why my phone will not pull emails?
thank you!

Exchange Active Sync Draining iPhone Battery Quickly. Help?

Exchange Active Sync seems to drain battery on both Iphone 4 iOS4 and iOS5 software platforms. I have 3 users that this is happening to. Users are on both AT&T and Verizon networks. Exchange is 2003 and the version is 6.5.7638.1. I’ve tried rebooting the phones (soft and hard resets), redoing push (Deleting the account and re-adding it), and restoring as a new iPhone (as a new iPhone not from backup) with no success. When you are in the mail account you just see the account trying to sync constantly, the battery drops like a rock, and the battery gets hotter than usual. This only seems to happen to users after they go away for a weekend trip or leave the geographical area where they live. I’ve even updated roaming capabilities on the phones. These are not the only users I have. Myself for example, I have exchange set to push, I’m on the Verizon network, and I have no problems. Does anyone know how to fix this issue?

I've been looking into this for about a year off and on. More recently it seems to be iPads/iPhones that are the worst. Even the latest iOS 5.x. It does seem to be people who travel a lot and/or jump on/off wireless a lot.
Deleting the device partnership does at least for a short time, resolve it in most cases.
I have a little script I run against the logs to show top user syncs. Basically, they do sync constantly all day and night up to 80,000+ hits per day on the ActiveSync frontend server (Exchange 2003), which is about every second or two. I know of a couple of people who got new phones because there battery was dying like crazy. It was just the sync problem killing them.
Anyone else have any info regarding WHEN this starts happening for a device?
It also happens with Android and Windows phones. It may be worse on iDevices for us because a lot of the people traveling have iPhones and/or iPads.

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.

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.

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.
