Battery Failure after 2.2 update!!!

I have an officially unlocked iphone which I purchased from Australia.
I live in England & Spain so needed it unlocked for orange in both countries. All was OK but...
I updated to 2.2 now my battery life has crashed from a couple of days to 6 hours
I had on wifi, bluetooth 3g etc. I have read battery faq's and switched off bluetooth and wifi ( I need 3G )
I have done an itune restore after backing up my iphone to no avail.
any help please?

Read the many threads here about holding down the home key to shut down Safari next time you use it, and also deleting and re-creating any Push accounts you may have.
Hold down the home key for 8 seconds when exiting safari seems to fix the problem for many.

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.

I Have been getting BAD battery life after the ICS UPDATE !! on the DROID RAZAR MAXX have this happen to any one else ??????

i have been getting really bad battery life after install ICS on my droid razar maxx i can only go 1 day and 3 hours where i used to be able to go 2 day easy have this happen to anyone else can someone tell me how i can make my battery life better??????/ and do i need to let my phone go complete dead before fully chargeing it again ??????
before install the ICS update i had 30 percent of battery life remaining so i pluged it in and let charged for a little bit while it updated my phone and ever thing after it updated i unplug my phone and started playing on my phone to see what ICS was all about but when it got to 15 and said " connect to your changer so i did !!!!! should i haved let my phone going complete dead since i unplug without it fully changer or does it matter ?????????????? if someone could please help me !!!!:)

What was your battery reading right after the update when you unplugged the phone? I have never let my Maxx drain further than 20% battery ever before I charge it. Yesterday after the update I also played more with the phone trying to learn the OS, as did most everyone on this forum. Give it a few days of your normal use before you decide your battery life has decreased. I took my phone off charger today at noon, it was 100%, and now it's 80%, with about 30 min talk time, and mostly standby. that's about normal batt life for me, maybe a little better than before the update. I'm still going to watch it for a few days before I make a conclusion about battery life.

Pathetic Battery Runtime after SMC 2 Update

Hey all,
I was very happy when I purchased my brand new MacBook Air latest edition (2013) back in May 2014. It used to give me over 14 hours of run time ALL the time and used to go upto 17hrs if I used to turn the keyboard backlight off and bring the screen brightness close to 35%. After the SMC 2.0 update, I've been very unhappy after what the update did to my notebook. Even EFI update didn't help at all. I contacted Apple customer care after 24 hours of update and they said nothing wrong has happened and everything will be back to normal once Spotlight is done re-indexing. Well, today I saw Spotlight running and it ate up my 100% fully charged notebook battery within 1 and a half hour. After disabling Spotlight completely via Terminal, the notebook is hardly lasting 4 hours now running the same apps that I used to run before and even for it to last 4 hours, I need to bring the brightness down to 20% and turn the keyboard backlight off. WTH?!
I use several Apple devices and excluding iOS devices, everytime Apple has updated something major (OS, firmware), they completely screw up my brand new machines. I had bought a brand new dual-core i5 Mac Mini just a month before Mavericks update showed up and before that, the machine was lightning fast in everything (with 8GB RAM) and after the udpate, it has become so slow it takes 4 minutes to boot up (without any single startup apps running) and then doing everything takes some seconds to respond. Nothing that I did helped to make it faster and had to finally purchase another fresh brand new Mac Mini after a few months while the old one (which was only a month old at the time Mavericks was released) is now eating dust.
I'm very annoyed by this, Apple, when I have to waste hours and days hopelessly trying to fix my brand new machines instead of getting work done. I'm including the URL of a screenshot (http://www.coddent.com/media/macbook-air-snaphost.png) which shows how pathetic my MacBook Air's condition is now (which makes me want to smash both my head and the Air with a hammer). Safari was running with 3 simple tabs with very simple text content pages at the time I took the snapshot. Sublime Text was running with 2 tabs open and was minimized. Terminal was minimized with no commands running.
Can anyone from Apple tell me what should I do with my Apple machines? I have always bragged about how nice Apple products are after buying each of them and have recommended your machines to several of my contacts who ended up buying one or other Mac products and then these type of horrible things start happening with my machines after any major update. How do you think I feel about your company in this type of situation?
Is there any solution for this or you want me to buy another MacBook Air now (which I'm totally not going to buy again, not a single Apple product anymore if this problem persists)?
EDIT: updated the screenshot URL.

Hi PlotinusVeritas,
Thanks for trying to calm people down about this battery/spotlight problem, although I'm still annoyed that they have such awesome software developers and still nobody gave it a proper thought on balanced file indexing rather than screwing up everything else to finish the indexing. For me, work is more important than the indexing madness which I hardly make a use of (and there are way too many people like me who do the same). It's extreme sad time for humanity if humans (who wrote softwares) can't control the software themselves. Spotlight is one of those softwares that laughs at your face while you're going all crazy trying to figure out what went wrong with your machine and should either be fixed, improved or completely removed from the OS.
In general, I'm a big Apple fan but it troubles me when they take forever to improve softwares like Spotlight. It totally was Spotlight which showed 20% battery left merely 1.5 hrs after fully charging the Air. I've been running the Air on battery since the time I created this thread (and disabled Spotlight) and now everything seems to be fine. Is there any utility that you know of that can allow me to set indexing only when the system is idle and keep it disabled while I'm working?
Thanks!

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

Battery issue after 8.3 update

BAttery drains like ****.. Overnight drain increased 1% to 15% after this new update. Cant use phone handy need to be charged after A hour or 2

Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose any data by resetting, but it can cure some glitches.
If this does not help, setting it up as new device would be the next step:

Battery failure after downloading battery update 1.2

Last night I downloaded the battery update for my Macbook; however, after doing so there was a 'X' showing over my battery. Whenever I unplug the laptop, the computer shuts down and does not read that there is a battery present at all. I have tried taking the battery out and putting it back in, but I can't figure out how to get my computer to read the battery again.

First try resetting the PMU/SMC.

Battery failure after software update for nokia n8...

I recently upgraded my n86 with the latest firmware..now the problem is the battery dies very fast .The phone gets heated while on charge and even after leaving it 5 hours on the charger the phone is still showing that it is charging.plz help...

Hmm, I'm about to think this could be a faulty battery. Do you have any spare battery to try?
Anyway, I don't know what a Nokia care point would do, as I don't actually know what's wrong with your device. There could also be a hardware fault in your device which accidentally appeard at the same time you did the upgrade.
Click the "contact us" link at the top of this page to get contact information and find your nearest care point.
You cannot roll back to older fw.

Awful battery life after latest OTA update

I've owned my Bionic for about 16 months now, and up until recently, have been very pleased. After the initial Jelly Bean update, I was enjoying the best battery life I had ever experienced, up to 20+ hours with moderate use throughout the day. However, the latest over the air update (I remember hearing my phone restart itself after the update in the middle of the night), my battery life has suffered dramatically. At first, I thought the battery was bad, so I ordered a new one, but the problem persisted. I searched online and discovered others were experiencing similar issues after updates. I have tried various solutions, included wiping the cache, deleting apps one at a time to determine a culprit, and eventually even a FDR, but none have helped.
I am almost positive the issue is stemming from "wakelocks" and other things waking my phone up again and again, even with the display off. My battery will drain from 100% to 40% as I sleep at night, even with WIFI and data disabled. The battery stats show Android OS and/or Display (they alternate) as the leaders for my battery usage, usually around 40-50%, which is much higher than it used to be.
I have become increasingly frustrated with this issue, as there seems to be no known solution other than getting a new phone. I find it almost inexplicable that an update could go out that causes such problems. My phone has basically been rendered to a tethered device, as I can't go more than 8-10 hours without recharging. If there are any known solutions, or if I can possibly receive a new Bionic, please let me know.
Thanks.

After the Google logo appears and I try to go to step 5, I get the green
little robot on his back, 'tummy' open with a red triangle and exclamation
mark in it....and it stays there for a long time???
Then the phone reboots....problems stay.
I do not know who you are Kevin but I was at the Verizon store on Friday
and I was told to call customer service as they are not responsible for the
software...it's Samsung's problem!?
I am a +$300 a month client and this is the service I get!
I will close my account, pay whatever it takes and go someplace else if
this doesn't get fixed fast...this did not happen on my request and I'm
stuck with it.
Respectfully,

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.

Poor battery life after Mountain Lion update

I updated OS on my 2011 13" MacBook air from "Lion" to "Mountain Lion."
My laptop used to last 5-7 hours with a single full charge. After installing Mountain Lion, I can't even last 3 hours.
I noticed that other people are experiencing the same problem but I can't seem to find a solution.
Any suggestions?

Droid DNA battery life after kit kat update cut in half

Since the kit kat update, my battery has gone from lasting about 13 hours to barely 7. If I am actually using the phone heavily it's less. If I look under usage, Android system is shown at 76% with Facebook being next highest at 6%. I haven't installed any new apps since well before the update.
I'm also experiencing a very long delay in opening sms messages- about 45 seconds, with considerable delay in sending as well.
Any help here? I use my phone almost exclusively for texting and Facebook messaging, as well as taking pictures/using Instagram.

In response to the list of items in the first link, I've verified the device is undamaged, and I am using the replacement charger sold to me in the Verizon store. My original charger cord came apart within a few weeks of getting the phone.
I've done a soft reset several times in the last few weeks. Doesn't seem to make a difference. Software is up to date which is where my issue seems to be coming form.
I'm still using the phone in the same manner as I was before the problem occurred. I've removed or disabled any apps I do not use only a few weeks ago. I have put the phone into safe mode as of this morning, so will see if the battery drains as quickly with with almost everything disabled.
The phone is generally connected to wifi within our home and always has a strong signal. Display settings are set for the display to sleep after 30 seconds, I am not using live wallpaper, and my brightness is set at about 75%.
GPS is turned off.
I'm not sure what my syncing settings are set at, but they have not changed save for one item that was altered when the latest update rolled out. After the update, Google offered me an auto-back-up service for my photos and videos (uploading them to my Google account) which I turned on. I've turned this off for now. Otherwise my settings for push/pull are unchanged.
I don't stream audio or video from my phone with any frequency (less then once a week). I have not yet done a device reset. Hoping to hold off on that if possible.
Even in safe mode, there is still an extremely long delay in accessing my SMS messages. That has not changed. I will update more at the end of the evening or tomorrow.

Your Battery Life after Lumia 800 Update

Hi,
I recently updated my Lumia 800 to firmware (1600.24838106.11500) and my battery life is much much better. However, I am still not seeing an expected fixed full charge of ~ 1502mAh, which it had before the update. Nokia says it may be an issue with the phone but before I send it back could any else confirm that post update they can get a max capacity charge reading in the 1500mAh's? Could there still be a little more battery charge a firmware update could tap into for all of us or is my battery weakened by pre-update battery management? My battery at the moment polls:
1) Battery Saver Life remaining around 1day 9hours.
2) Battery Status Full Charge Capacity varies between ~1350 & 1420 mAh.
3) Charging using approved Nokia Lumia 800 chargers.
3) Three charging cycles completed.
Cheers for the help.

After the update and a hard reset;
The max battery ranges between 1322 and 1478
For the 1st few days I was getting about 26hrs out of it so quite a leap from 6-9hrs but this morning the phone was dead after 16hrs - with most of that time just on standby.
Plugged in the charger and there's a battery charging image but after 15 mins I still can't turn the phone on to make a call (with charger in).
During this time my Blackberry 8520 was charged up on Saturday and the battery power shows 3 bars left out of 5.
The Lumia looks really nice but I think it's covering up internal outdated junk and the only thing that's keeping it selling is smoke and mirrors marketing.
335 hrs standby time - nearly 2 weeks!!!
55 hrs of music playback - over 2 days!!!!
It's like they plucked the numbers out of the sky... "this will sell it"!
My phone is now coming up to 2 months old and all this "there's a patch to fix it" has proved nonsense. Sure they've increased it a little but I'm sure I could have got more life out of it by setting the brightness to low myself.

MBA battery life after OS X update 10.9.2

Since I installed the most recent OS X update 10.9.2 for my 2013 MBA, my battery life has seriously decreased! I am not using my MBA any differently, after 2 hours of use the battery life went from 100% to 75%. Anyone else had this issue?

1. Check the cycle count of the battery against the limit for your model. The battery may be due for replacement. If the power adapter is connected almost all the time, the battery may need replacing even though the cycle count is not too high.
2. Follow these instructions, or these for OS X 10.9 or later.
3. In the Energy Saver preference pane, uncheck the box marked
Enable Power Nap while on battery power
4. You can also try resetting the SMC.
5. Make sure your system is up to date in Software Update.
6. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
