Battery drain with IOS 6 update

Hi,
I've seen already quite a few posts on this and I just want to confirm that i'm also experienceing a dramatic reduction in battery life. I updated this morning my iPhone 4, and the battery didnt make to 3 pm. (Normally lasted until night time, with about 20% remaining before plugging back in for a night charge.
If anyone finds a fix, please let me know!

Depends on what the cause is:

Iphone 4S battery drain with iOS 5.0.1

I am experiencing just about the same battery drain with the iOS update as I did before.
I was wondering how many of you had the battery drain problem, updates to iOS 5.0.1 and had that actually solve your battery problem.

I have IPhone 4 and I updated the IOS to version 5. After the update the battery lasts about a day. After the update to 5.0.1 the battery lasts a day and a half. It is an improvement, but not as I expected.
The next step is to disable configuration options like:
- downgrade from 3G network to 2G
- disable Data services
- disable automatic clock
- disable location services
- use the phone only as a phone and nothing else.
I will come back to tell how much the battery lasts.
PS: the IPhone 4 is new so there is no problem with the battery itself.

A fix that works for your battery drain with iOS 8.2

After I updated my iPhone 4s to the new iOS 8.2 I found my battery life had become terrible. I could barely make it through an 8 hour day at work before my phone would die. It was so bad that I had to get myself a second charger to plug it in during the day. Even then, if I used the phone at all, it would still lose its charge while plugged in.
Before this update, my phone would easily last through the day and would not need to be plugged in before I went to bed. Even at midnight when I'd go to rest for the night, my phone was never below 70% and most times it would still be well above 80% but not so with iOS 8.2 So here is a fix I found on another forum somewhere. I was desperate so I tried it and low and behold, it worked great.
Here goes:
Let your phone die completely until it turns off by itself
Plug it in your charger until it comes back on again (around 6% for mine)
Turn it back off using the top button and the slider on the phone
Leave it plugged in for 2 to 3 hours or until you figure it would have reached 100%
Unplug the phone and turn it on
Now reboot your device (turn it off and back on again)
That's it. This fixed it for me and for many on the forum where this was posted. My battery life is back to what it was before my update to iOS 8.2. I have plenty of battery life left when I get home after work.
Try it and pass it on....it works.

Use the Settings app to determine what apps or processes are using your battery the most. Once you know what is causing the battery drain you can take steps to reduce it.
Settings > General > Usage > Battery Usage
Wait a few seconds for the device to bring up the list of apps with their battery usage.

Resolving battery drain with iOS 5 (not 5.0.1)

Hi
New iPhone user (first iPhone). Unlocked 4s 64Gb. iOS 5 United Kingdom
NOT impressed with battery drain so far and reluctant to "upgrade" to iOS 5.0.1 On standby (most services set to "off") phone has decent life (looking at about a week bofore the battery dies) but as soon as I start using the phone - eg browsing over WiFi, battery drops like a stone (4% in 20 minutes).
I can see lots of folks upgrading to 5.0.1 and doing a full battery drain, full reset & set-up as a new phone and this seems to resolve some issues.
My question is, does this same technique work with iOS 5??
Hopefully 5.0.2 (or whatever it is called when released next week) will sort this out - otherwise the 4s goes back to store for a refund.
Any comments gratefully received.
Cheers
RB

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 with iOS 8.1.2

I am having severe battery drain issues with iOS 8.1.2 with all my iOS devices (iPhone 6, iPhone 5s, iPad Mini Retina, iPad Air). I can have my device in DND mode overnight with 100% battery, then the following morning I will wake up to find my device down to 20%. The battery usage graph shows nothing abnormal, just very rapid battery drain. What gives?! I saw a couple other threads mentioning this issue. I have attempted Network Reset and verifying Bluetooth is off, but this is just crazy. Anyone else get a resolution on this or experience this after iOS 8.1.2?

tldr; Check the secd process on your Mac. If it is consuming greater than 50MB of memory...turn off Keychain sync on ALL your devices.
The Full Story
The last few months I've had instances where my iPhone would start getting really hot in my pocket, and the battery would drain at 3x the speed. After much research I also discovered that a process on my Mac (secd) had a vicious memory leak and that single process was consuming 13GB of memory and paging thousands of console messages. After discovering that the process was related to Keychain sync, I disabled keychain sync across all 5 of my devices. Immediately, the battery life on my iPhone was restored to normal.
After I reenabled Keychain sync across all my devices, everything would run fine for a while, but after a few weeks, the problem would resurface. And I would repeat the process of turning it off on all my devices, to effectively reset the iCloud keychain data.
Anyway, Apple does need to fix this, as it affects performance on both OSX and iOS.

Upgrade to OS4.1 causes fast battery drain with WiFi on

I've just upgraded the software on my 3G Pod to 4.1, only to find that it has led to a much quicker battery drain with the WiFi on. Is there a fix for this or can I revert to the previous OS?

Owen Glyndwr wrote:
Thanks llaass, but the discussion that you direct me to does not really address the issue of why a very recent upgrade should make such a significant difference. I had already realised that turning off WiFi makes a difference. Perhaps my question should have been addressed to Apple, since it appears that it is their so called 'upgrade' that has led to a deterioration.
I'm using iOS 4.1 on my iPod Touch 3 gen with no battery drain problem. This suggests that there is another factor at play which must be present to provoke this problem between the iPod and iOS (i.e., a specific App, a router type, or ?).

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:

OK under“Charge Information” you see my MBP currently at 7806mAh (mstands Milli

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.

Battery drain with 2 Push accounts Mobile Me and Microsoft exchange:

One might ask why I need two. Well, I started with a Microsoft Exchange account,, and now am trying Mobile Me. For now they are both being pushed to me. Do I get extra drain from having 2 accounts? I wonder if I get twice the drainage with 2 instead of 1 account. I had done a restore from backup when I got my new 3GS,, and didn't notice too much drain, but thought I could do better, so I restored a fresh 3.0 firmware, without a backup,, funny thing is, that I thought I would enhance battery life. So far, it seems worse than my restore from backup . All that work, with little improvement to show for it

You are going to get more battery drain with the 2 push accounts. Try removing the Exchange account for one day and see what happens to the battery life.

Am I the only one experiencing battery drain with the 6.1.3 upgrade? It went from 100% to 63% in 7 hours WITH NO USE!

Am I the only one experiencing battery drain with the 6.1.3 upgrade? It went from 100% to 63% in 7 hours WITH NO USE! I've had worse luck with the i5 than the i4. This is the first time I regret being in a two year contract. I might add that this is my 3rd i5

So now 12 days later and another replacement I'm still having issues and apple still isn't helping. My phone has started shutting off unexpectedly again today. Does anyone have any suggestions on where to go from here?

Why doesnt the Ipod touch 5th gen have Battery Percentage with IOS 7?

I read that the Ipod touch 5th gen will have battery percentage with IOS 7. But so far it doesnt. Just wanted to know if this was a lie or if something happened and apple decided to remove it.

"Battery percentage in status bar added to iPod Touch (5th generation)"
I seen this
and i have seen pictures of the Ipod touch with the percentage next to the battery on the apple website.

Settings -> General -> Backroung App refresh
Either selectively disable the ones you do not need, or just disable the feature altogether. Esepcially for apps that would be using location services, this has the potential to be a huge battery drain.
Also, in Privacy under Locations services, system services, disable at least the "popular near me" and "location based iAds" - both of these use location services a lot as they try to track your movements in real time. You can disable everything in system services if you wish (won't harm anything).

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 5 battery drain since iOS 8.2 update

hello,
my name is Udi, from Israel.
i have an iPhone 5 which i purchased in June 2013.
since the beginning, i have always kept the battery saving "rules", including correct charging of a lithium ion battery, auto-brightness off, reduce motion on, push notifications off, background app refresh off, cellular data off when not in use, etc. etc.
since updating to iOS 8, my battery life has decreased a little. but since updating to iOS 8.2 a few days ago, i have experienced, what is in my standards, a serious battery drain. e.g. when i sleep, with my iPhone on airplane mode at night battery decreases by ~15%.
i have tried everything, including restoring the phone and using a backup.
what can i do?
will a restore from scratch (without using a backup) help?
thanks in advance =)

If this does not help, get your phone checked by visiting an Authorized Apple Service Provider or Apple Store next to your place, or contact Apple Support and talk to them. They can check the battery online.
You can also visit this page to do that: iPhone - Contact Support - Apple Support
Click on Apple Support, then on ->Battery, Power &Charging ->Battery questions and troubleshooting, and follow the instructions.
