iOS 6.1.3 battery drainage

Had the problem, it was critical, like 0.33% of battrey loose per minute.

Yesterday I turned off 3G, cell datas, and location device.

Loaded my battery all night, disconeted it in the morning. It was 2h30 ago, battery is 98%.

It makes 150min and 2% of battery loose, 0.01% per minute.

Ten days ago, I purchased a new ATT 4s to replace my cracked 4 (which still worked fine, just tired of reading thru the cracks) When I went to sync, I updated to the new ios. I had a week of reading these boards and trying all the tricks to understand why the battery was draining so fast. I did 2 restores. I turned off everything, did hard resets, etc. I went back to the Best Buy a few days ago and exchanged for a new phone. I synced and restored but did not update to the new ios. Everything is now back to normal. I am running all I used to run on the 4, am back to backing up in the cloud, and generally just using a smartphone the way it should be used. I am so happy! There must be a problem with 6.1.3. I will still run 6.1.2. Good luck everybody.

As always, there are multiple issues that effect battery. So one fix won't solve every bodies problems.

Earlier I turned push off from mail, contacts and calendars and also on the advanced section.

At that point my battery was at 52% and I had 2 hours 15 mins useage.

Now my battery is at 40% and I have 4 hours 9 minutes usage.

It's too early to tell, but so far my battery life appears better. 48% got me just over 2 hours and now 12% has got me just over 2 hours.

Since 6.1.3 my battery has been dead within 4-5 hours usage. Now it looks as though its going to last a fair bit longer.

Ill update the thread tomorrow.

I've got an hour usage and 95% battery left. 2 hours standby. Yesterday it would have been on 80% by now.

It's worth double checking your Push settings and turning off sync in Chrome if you have it installed. (even if you're not actively using it).

I got help from turning off all unused apps ...and from SYS ACTIVITY Manager app and their FREE MEMORY clearer.

BUT MOST from turning off MAIL and iClould period..

My phone right now has been off charger for 5 hours ..used to play music for 2 ...and has 97% charge!

You can turn just 3G off. In mobile data, simply turn off 3G but leave Mobile Data on. This will mean you'll still have internet access but you won't have 3G. Edge and GPRS will still work.

However, Edge and GPRS are so slow, I find it unbearable. Though perhaps turning off 3G while you're not using the net is a good idea.

Although my battery is fine now.

have you tried backing up your phone creating a new user profile on windows & redownloading itunes sometimes the IPSW file that you download from Apple via itunes by wifi doesnt correctly update to your device. If you have done update via the cable your best to speak to them on 08000480408. The problem with issues like this is their isnt a similarity to each persons problem with Battery drain & wifi issues as we all have different apps & content on our phones. Always wondered wether the Diagnostic & usage does actually help to improve their products or if like other Manufacturers they just include this to make us the consumers believe their is going to be vast improvement all thanks to their reporting tool.

If usage and standby times are the same there there is a process thats running all the time. If you have not installed any apps and only have the defaults then you can try a DFU restore (google it) or take it to Apple store for diagnostic. Some process is running but from what you wrote there is nothing left. Typically that issue indicates email, iCloud, or calendar something like that hung up and running constantly.

I agree. There is a virus. It's called iOS 6.1.2 & 6.1.3.

iOS is reporting the wrong battery %. Plain and simple. It will shut down at 1% or 5% or 10 or 15%.

This morning. Woke up. 100% full charge. Used for 5min exactly. Down to 98%. Restarted the phone. Comes back at 100%.

Few days ago I reset all settings. Worked great for about 4 days. Now back to the same issue.

If I restore the entire thing and not include iCloud or Mail or whatever you guys are talking about. Guess what? Works great. For about 4 or 5 days then after a few charges. Back to the same problem.

A friend's iPhone 5 is shutting down at 4%. It goes down from 10% to 4%.

I'm getting 4 hours usage on a good day. iPhone 5's getting 5 hours.

The problem is iOS. iOS 6.0 was working fine. I could get 6 hrs and 30 minutes usage on this phone. Same phone. Update. 4 hours.

You tell me this is some virus/rogue app? Boloney. It's iOS 6.1.X. It *****.

Reporting wrong battery life (and no. It doesn't stay at 1% for an hour. It just dies).

It says its 100% when it isn't 100%. It is totally unstable.

Then the Apple fanboys say the solution is to turn off all the features of the phone. So if you're an iPhone user your phone can't Push your mail, it can't use any location services, it can't have any Cloud services, and it can only use Cellular Data 3G or 4G ONLY when you want to go on the Internet. Otherwise you have to disconnect.

Ahahahahahaha!! And this is a fix? How about you just get rid of that crap and get a real phone?

I bought a Mophie case. That's the only way I'm getting through a day. iPhone 4S, soon to be my Wife's phone. I'm getting an S4.

I feel you.

I know it isn't Pandora or anything you are doing. It isn't your fault.

This morning I woke up. It was at 100% full. 5 minutes went down to 99%. Restarted the phone. Came back and it was at 100% again.

So. I did it again.

1) Plugged it in until it showed me the plug as fully charged.

2) pressed the sleep and home button until it shut off. Did NOT unplug it

3) wait until its back to the lock screen. then unplug the phone.

Then it was normal. It took about 15 minutes to go to 99% this time. It is always the same thing.

Also, I just turned off iCloud for the time being because it's eating through my data. This isn't the issue as you can see though because you don't even had iCloud set up.

Unfortunately for us, all the "fixes" here end up with a hard reset of the phone. But it's not a fix. Slowly but surely the battery life will blow again.

No need to do a reset to calibrate the battery charge %. All IOS devices calibrate the battery level automatically when doing a 'deep cycle' recharge. All you have to do is let your battery level get to the point where the battery icon turns red and do a full recharge (Red % varies by IOS device from 10% - 20%). This will start a deep cycle charge mode. Apple recommends to do this at least once per month to maximize battery cycle life. The battery level will never be exact as sbailey4 says because the % shown is based on the precise voltage it reads at any given time. Battery voltage will fluctuate with temperature changes and how much current is being drawn by the device. Apple samples the voltage level every minute or so and averages the results to calculate the % to display. This is why you sometimes see a jump in the % indicated. For example if your downloading a movie the % may drop several points and then jump back up once the download finishes because of the voltage changes, the same for a significant temperature change.

Hi. I downloaded my apps one by one from the App Store over WiFi. I can't comment on whether doing the same over GPRS produces different results as I didn't try that. I did origianlly try restoring in iTunes then recovering all my apps and data from the back up and that most certainly did not work for me.

Will be interested to hear if your phone stays fixed especially as I often run some of the apps you mention.

My 4S had been suffering with terrible battery and has been running warm in my pocket when it should be in standby since some time after upgrading to 6.1.3. My standby and usage times are almost the same values and yet my phone is barely used during the day except to receive emails from icloud. Following it also consuming my monthly data allowance (which has ****** me off), and having tried all other things like disabling iCloud functionality I decided to take the drastic step of wiping and setting it up as a new device, then downloading apps back on to it. I also had to use some convoluted steps to restore some data to apps.

That was about a week ago and afterwards battery life was excellent - after several hours it was still on 100%. By the end of the day, it was 70%. A week later though and it has suddenly returned to being terrible and running warm in my pocket. This morning I did a hard reset (home and lock buttons until reboots) and the used the multi-tasking toolbar to kill off every single running application incl. the built-in Mail, Phone, Contacts etc.. until nothing was left. I think I've turned off Safari iCloud syncing too temporarily to see how that affects things.

Since then battery life has returned to being good but I suspect there's some issue of conflict between some apps and the updates to the iOS, or that there's a memory management bug somewhere that takes a while to manifest. It maybe that your upgrade to 6.1.4 has temporarily done the same reset for your device and the problems will start to reappear after a week or so. For reference the only apps that I have run today (and therefore show in the multi-tasking toolbar), seemingly without problem, are:

Notes (iCloud synced)

App Store

LED

Remote

Phone

Mail

Settings

Photos

eBay

Facebook

Article shows Facebook waking up every few minutes and doing something for 10 seconds each time.

Utter joke. Apple should ban apps from doing **** like that.

I'm gonna ensure I close Facebook properly each time I use it and see if it makes a difference to my battery.

As far as I'm concerned, there is NO permanent fix to the issues with webbookmarksd.

In the last 6 1/2 months I have fixed this issue 3 times, after deleting my bookmarks database on my MacBook to ensure a clean non corrupt version, doing the same within my iOS Backup using the outlined methods iBackupBot, then setting the phone up as new. The fix lasted approximately 1 month before I had to fix again and did this a couple of times before going the next route.

Specifically, since April, I've set up my phone twice completely as new, manually putting everything back on my phone, not restoring anything whatsoever from a "cleaned" backup, and turn off and do NOT use iCloud syncing of Safari data on my iPhone as well as NO iCloud syncing of Safari data my MacBook. Webbookmarksd has begun to run amuck within a week each time.

Additionally, even though syncing of Safari data is off everywhere anytime Safari is launched on my iPhone the "webbookmarksd" process starts up and continues to run until I either kill the process or force close all running apps and reboot phone.

One would think that if iCloud syncing of Safari data has been turned off, then webbookmarksd shouldn't continue running amuck, unless of course the more obvious being that there several other integrated processes making calls to webbookmarksd that have nothing to do with the syncing of bookmarks, reading list and VISITED App Store pages.
