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.

Pandora battery drain after ios 8.1

I've been using Pandora for quite a long time. I usually leave 1 earbud in and stream music all during my work day.
This has historically used 30-50% of my battery during a 9.5 hour shift.
Since IOS 8.1, Pandora has gotten insanely battery hungry. Since 8.1, my battery generally dies around 4p.
After 4.5 hours of streaming today, my battery is at 48%. Typically, it would still be in the 60s-70s at this time.
Usage shows Pandora taking 69% of the battery power, so it's definitely something between IOS 8.1 and the Pandora App.
Note: I did not have this problem on *any* previous version of IOS. 8.0.2 worked just fine.
Has anyone else experienced this issue? The sole change was IOS 8.1, although I do not know if it's the culprit or Pandora.
Thanks for any insight..

Same here. Listened to Pandora on iPhone 6 on vacation while driving (up to 8 hours per day) no problem. Battery drain about same as with previous iPhone 5 (can actually listen for 7-8 hours without going below 30%).
Updated to 8.1 on Sunday, phone went from 100% at 7 a.m. to 50% 40 minutes later during my morning commute and when I picked up phone it was extremely hot to the touch.
I guess I don't get the "fix" that Pandora is working on (daddydev). shouldn't Apple be the ones working on the fix to their 8.1 update, not the app developer?
When I contacted Apple support, they seemed unaware of the problem. Maybe we are the only 4 iPhone owners who use Pandora? I don't think so.....

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!

IPhone 4 Shuts Off repeatedly and battery drains after ios7 update

This morning at 5:20 am, my alarm went off on my iphone like normal, I plugged my 100% battery charged iphone out of its charger and within 30 seconds it turned off. I quickly plugged it back in the charger and it dropped to 41%. Then as I had to start my morning and get to work and take the phone again out of its charger, it died again. So I got to work, and I have put my phone to "charge" while plugged to the charger, but as time passes, instead of charging my battery it looses life, then I recieved a notification to update my phone, which I did however this did not help my phone, it still continues to turn off once I plug the phone out of the charger.

Same here. My ipad mini used to last weeks, now I can barely get a full day out of it, after I finally updated to ios7. And yes I disabled every possible battery drainer I could find and rebooted. This is clearly to me a bug for the mini, possibly their code that drains batteries on older devices to force people to buy new hardware is running faster than it used to when it would only kill your battery twice as fast, perhaps something else I would hope, but I'm about to hack my device and return to ios 6 as this is absurd. I can put my ipad down for a few hours and pick it up with a 5% drain or overnight with a 70% drain.

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 ?

Lumia 820 battery drain after "Black" update

Hi all,
Yesterday I finally received the black update on my NL820. After applying the update successfully I charged the phone to %100. Before I went to bed I had:
Battery at %94
Wifi - Off
Data services - Off
Location services - Off
Bluetooth - Off
Battery Saver - On
This morning I wake up and it is unusually bright outside - the phone powered off, the alarm didn't go off and I overslept for work. I haven't touched any other settings after the update. Everything is the way I used it before. What is it that could drain a battery in the space of 8 hours from almost full to power off? I've had this happen on the same phone twice prior to the upgrade as well but then I thought I've forgot data services on or something. This time I'm sure everything was off.
Please advise.
Martin

I have been using Lumia 820 since 1 year and have never faced any issues. But after the recent "black" update... my mobile battery drains out within few hours after i charge it 100%. I have to charge it 3-4 times in a day ..
1. I dont have any GPRS connection.
2. I use wifi at home (only evenings). The rest of the day.. I use it only for calls and texts.
3. I have tried hard reset, but that dint help.
4. After hard reset, I dint update my mobile software.
I charge it till 11pm and when I wake up at 5 am .. I see the mobile is switched off and I cant depend on the alarm to wake me up . That makes me so nervous.
Please bring out some solution to this problem. It is so irritating to charge the mobile for so many times in day.

Battery drain after lion update

Anyone having problems with there battery draining faster after updating to lion

Here's what I posted for other forum troopers: please note ***** comment at end
Ok here are my recommendations for your consideration:
Goto the “apple “on your top menu bar. Click 1stoption (About this Mac) a small screen will appear
and click on “More Info...which will take to a large another smallscreen with Mac Book Pro in huge
l letters like this: MacBookPro.
Next gothe “Systems Report” button: press.
Next Under“Hardware” on the left you'll see “Power” click that.
                  Volia the battery info:
Now lets do a bit of an analysis of the info: here's mine a 2 mo. old 17” MBP:
ModelInformation:

Manufacturer:     DP

CycleCount:     17
Condition:     Normal
BatteryInstalled:     Yes
Amperage(mA):     2131
Voltage(mV):     12534
OK under“Charge Information” you see my MBP currently at 7806mAh (mstands Milli
which is 10 tothe -3 power) which translates to 7.806 Amp hours in non-techiespeak. As you see on mine Full Charge Capacity is 8.488 Amp hours.
Ok under healthyou see my cycle count is 17. Your very low cycle count reflects that you are not “conditioning” your battery by runningit on battery till 5 minute warning or going to sleep and then fullyrecharging it! You've had it ~18 mo.
And your dooming yourbattery to a short life. Condition your battery for a long life.
Please notethis is a super battery 2.131 Amps @ 12.534Volts which

Hello, skypeisawfull-,
Thanks for submitting feedback about the battery life of Skype for Android. The developers of the app are making great strides to improve the functionality and other aspects, including battery life, so that it runs better for its users!
Skype, by nature, does use more battery than many other apps. It should be understood that it has to constantly contact Skype's servers in order to receive incoming call, chat and contact data. You can reduce the amount of battery usage by closing some other apps that you do not use, reducing screen use time, ensuring that you are in areas with good reception (because cell standby greatly reduces battery) and rebooting the phone after a day or two can make a difference in your battery life.
Remember that the development team has surely made it a priority to make the app consume less battery and kill off the bugs that cause that. They probably have more in store, so just you wait and see! Things could be looking good! With you posting this, they'll take notice and probably work to reduce that 26% usage to something lower in later updates!
Thanks for the feedback - keep 'em coming!

Heavy battery drain after OS Update 10.3.1.1779

couple of days ago my phone (Z10) upgraded to new software version 10.3.1.1779. Now the battery barely lasts four to five hours. Usually not more than four. Is this a f****ng joke, Blackberry?!
I checked and I constantly have PIM services at 30-40 %, which is the main battery drainer. Following the suggestions on some of the forums I tried deleting accounts and found one that - being deleted - solves the problem. However, when I add it again it drains the battery again. The point is that i MUST have it on. this is mail only, no calendars, contacts. When I add it I left the phone overnight to download all it needed, 12 hours later PIM services still run at 30-40% all the time.
Reloading the software does not help either.
pls help, I am running out the ideas... I can't keep my phone connected to charger at all times...

After any OS upgrade on a BB10 device, it will take 48-72 hours for the device data syncing of email, contacts, social apps, etc., to complete and finish. High data transfer after an upgrade cause high processor use, which in turn causes high battery usage. Likewise, high processor use will cause some lag and initial slowness. Ignore and and be patient. It can take the 48 hours for all contacts to sync back to the device. And, the battery will recover after a few days. Just don't drain your battery to 10% or less each time, top off the charge. You'll notice a difference after a couple days. Additionally, look at your Device Manager and in the top pull down menu tap LAST 24 HOURSTap the Battery tab at bottom. What are the top 3-4 processes draining the battery?Tap the CPU tab, what are the top 3-4 processes using the CPU?

Battery drain after win10 update

Hi everybody! Recently updated to win10. No major issues so far. My only problem is the battery drainage. According to specifications, my laptop has a 6 hour work time when unplugged. Ever since I updated, my work time has diminished to 3hrs max. I had no problems woth my battery so far, that's why I believe that it has something to do with either Windows or drivers. I have installed all updates from HP support assistant. I have also tampered with the power saving setting with no success. Any suggestions? Thank you!!!

Thank you!!!Does your battery drain when you sleep the laptop or shut down. There is a major problem with drivers and Windows 10, because my laptop would not sleep or shut down, unless I did a hard shut down my battery would drain very easily.

TS1702 Lost all my documents in pages after ios update on both iphone and ipad

Have anyone else had that problem? And what did you do? (Except from crying)

Eek! I don't know how I save as a file, so no. As for iCloud , I did back up last week but am not too sure if it was before or after the update. I don't even know know how to find out what was backed up on iCloud. I will look in to that now. Thankyou.

IPhone 5 battery draining after iOS 6.0.2 update even on standby mode without wifi/ 3G at all.

My newly bought iPhone 5 was on iOS 6.0.1
everything worked fine and i had no wifi nor battery issues at all until I upgraded it to iOS 6.0.
i noticed some battery drainage even when i'm not using my phone at all it still drains 1-2% on standby mode with no wifi nor 3G at all in an hour,
If i use wifi it'll drain 4-5% in a few minutes time, more serious case when i use 3G, it's literally draining in EVERY SINGLE MINUTE.

Per designed, Wi-Fi will disconnect in sleep mode to save battery.
If you want Wi-Fi to stay connected even in sleep mode, plugin to a wall power socket.
No it's not "per design". It's not supposed to disconnect when locked/in sleep mode. The whole concept of having live notifications to work when your phone is locked is the standard for smartphones. Having this feature only accessable when pluging/charging the phone is rediculous and counter-productive. But it's good to know that I'm not the only one who has this issue. I hope all our issues are solved swiftly, good luck to you all

No wifi and horrible battery life after iOS 7 install on iPhone 4S!

After the iOS 7 install on my iPhone 4S, my battery life is markedly worse and my phone will not connect to my home wifi. Every other device, including my wife's iPhone 5 and two iPad 2's, still connect perfectly. Please help. I wish I could go back to 6.1.3.

I've had issues since the upgrade too-messages wouldn't load, phone locked up and would turn off at random times. Then I noticed my data usage going up a ton in one day and checked and it wasn't connecting to my home wifi. Called tech support and they went through all the troubleshooting they could find and nothing helped. Had to go upgrade. You might try to reset your network settings, but that didn't help with mine
