IOS 5.0.1 Battery Drain Bug: Edge Network

I think I may have identified a use case that is causing significant battery draining on the current iOS 5.0.1. The use case is when a 3G enabled device switches to an Edge network signal, it increases battery drainage significantly on the Edge network. This includes draining the battery while in standby. Enabling or disabling location services makes little difference. Phone does heat up on Edge, even on standby. Phone behaves normally while on 3G network.

I would be interested to see if anyone else has thought to field test the below scenarios:
Being on the Edge Network by itself causes significant battery life drain
If the process of switching betweeen 3G and Edge networks (network search process) causes the battery drain.
Does battery life behave normally when on 3G, with no network interruptions?
Does battery life behave normally when on WiFi, with no network interruptions?
Does battery life behave normally when device is in Airplane mode?
Does battery life significantly drain when 3G is disabled on device?

IPhone 4s with iOS 7.0.2 Battery Drains FAST!

My iPhone 4s with iOS 7.0.2 the battery drains tremendously fast! This morning it was 100% charged then just by surfing facebook and flipboard with 3G, it became 7% in the noon. I hope Apple can solve this problem! I'm very upset right now

I've pretty much proved to myself that this is a bug in 7.0.2. Since my post a few days ago I have:
Done a full restore of my iPhone with 7.0.2 - problem still persisted - draining battery at approx 23%/hour with no use, and with all the battery saving tips applied (no push notifications, no background updating etc).
Restored iPhone with 7.0 - battery drain dropped to approx 5%/hour with no use and battery saving tips applied. With push notifications & background updating turned back on, battery drain increased to approx 12%/hour which is high, but still significantly better than 7.0.2.
I would recomend everyone who is having this problem with 7.0.2 to lodge a bug report with Apple - www.apple.com/feedback - hopefully if enough of us lodge the bug report, Apple will listen and release an update.
As for downgrading, unfortunately we cannot downgrade to 6.x anymore, but you can downgrade to 7.0. It is a matter of downloading the appropriate firmware. Firmware's are available here - http://www.icj.me/ios - although that site lists 6.x, they will no longer work, so get the 7.0. That site redirects you to Apple's server for the appropriate ROM, so they are legitimate. Before you install it, you have to turn "Find My iPhone" off by going to Settings | Privacy | Location Services | Find iPhone. The installation seems to turn it back on when done, but you should probably check. Once the firmware has downloaded, you can install it on your device by going to iTunes, and holding down the option key while clicking Restore. This is on Mac - on Windows I assume you would press Alt (but if that doesn't work, try Ctl or Shift). If you have pressed the right button on your keyboard, a file browser window will appear, allowing you to choose the firmware that you just downloaded.
Once installation is complete, iTunes will tell you that there is an update available for your iPhone, just click "Later" everytime the warning appears.

IPhone 5s IOS 8.1.1 battery drain using mail

Problem: battery drain is unacceptably high with -1% per five minutes
Description: after upgrading from IOS 7 to 8 the battery drain on my iPhone 5s (32GB) has hugely increased. Several tips on the internet have been tried from turning off several services to reinstalling the IOS none with no improvement. After reinstallation the drain was acceptable only to result in again a -1% drain per five minutes after a week.
Expected: using IOS 7 I could easily use the iPhone throughout the whole day with -1% per fifteen minutes. After installing an improved IOS one would expect similar or lower battery drain
Tests: as said, severals tips found on the internet have been tested none with any improvement. Deleting all accounts under "Settings->Mail, Contacts, Calendars" proved to be the only solution for this problem (a non-functional solution I must add since I'm using this iPhone for communication...). Even keeping the iCloud account but disabling all iCloud services did not improve the situation, only a real account deletion worked.
Question: do you know how to get battery drain back to -1% per fifteen minutes whilst maintaining my iCloud and Exchange account using IOS 8.1.1 on an iPhone 5s (32GB)?
Kind regards,
Ronald

Since upgrading my iPhone 6 to iOS 8.1, my battery has not been the same. I was able to get 9-10 hours of usage before and am lucky to get 6-7 hours. AppleCare thought that was on the low side and told me to visit my local Apple Store for a thorough diagnostic testing of the battery. My appointment is tomorrow. Will report back.

IOS 8.1.3 - Battery draining very quickly

Since installing iOS 8.1.3 on my iPhone 6 the battery has started to drain very quickly with little to no use. Anybody else having the same problem

I too was having some serious battery drain on IOS 8.1.3 on my iPhone 5S. The phone kept getting warm (like I was using maps navigation) I think I just fixed it. On the hunch that it had to be something with location services I went to the following location in my phones settings: Settings->Privacy->Location Services now scroll all the way down and Click System Services. Disable Cell Network Search, Setting Time Zone, and Wifi Networking. You can also try disabling these one at a time. I really don't need these services so I disabled them all.
Your phone should now cool down and hold a charge like it did before, mine does. Here are what those settings you are disabling do:
Cell Network Search:This tracks cell tower usage and congestion, and sends the data back to Apple for analysis as to what towers are being used the most, how you move between cell towers, and which ones are overused. It does not help your phone locate a cell tower. Turning this off will not affect your phone’s performance, according to Apple.
Setting Time Zone:Your time zone will be instantly adjusted according to your geographic location. Ever notice how as soon as you turn on your phone after a long flight, it displays the local time perfectly, even before getting cell signal? It’s this setting. If you turn it off, you’ll lose that functionality.
Wi-Fi Networking:This particular setting is interesting, and requires some explanation. As you move around a city, your iPhone is constantly picking up WiFi signals. It geotags that data (“XYZ WiFi is at this GPS location”), encrypts it so that it is anonymous and unique (otherwise the data would look like all hotspots are named “linksys”), and stores it as what Apple calls “crowdsourced Wi-Fi Hotspot locations”. Next time someone walks by that exact hotspot, their iPhone will know where they are without using GPS – because you basically already “marked” the area. Shutting this setting off will stop that info from being sent to Apple. It will not affect your phone’s performance.

Possible solution to iOS 7.0.3 battery drain issue (iPhone 5).

Not a question as such, but for anyone who's having battery drain issues on iOS 7.0.3 and doesn't want to attempt upgrade to iOS 7.0.4 revision yet...
I was having some problems with battery drain with my iPhone 5 since updating to 7.0.3. The device is only about 5 weeks old so I was quite annoyed that I had issues with it.
This morning after a full charge I did a hard reset. Now the problem seems to have gone. I've had the phone on for several hours (about 4.5hrs) and it's only just dropped to 99% moments ago. This is a massive improvement (on even the battery life of the device when I got it, and it had 6.1.3 factory installed).
I hope that this helps anyone who doesn't want to risk 7.0.4 until it's had a chance to cool off and for people to identify/resolve any issues (as I am waiting too).

The update isn't the problem. It was a problem with your update process. millions of others have updated without any issue at all.
Also resetting has been discussed many times in the never ending battery draining threads.

Iphone 6, iOS 8.0.2, battery drain & overheating

So I upgraded to an iphone 6 from an iphone 5. The phone came with iOS 8.0.2. It seems that I am not the only one with this issue but my my phone gets hot after a short use and battery drains rather quickly. It seems to be a software issue since many people are exhibiting the same symptoms. My battery usage shows that the Home & Lock Screen ate up 26% of the battery and my settings ate up 22%. That seems a tad high. Battery is at 84% after 56 min usage and 4 hr 14 min at standby. Note this is on the initial charge after transferring my data from the iphone 5 to the iphone 6. Battery has not fully drained yet. What do you guys suggest? Thanks.

I have a similar problem on my 5s. Since updating it has stopped allowing me to send texts to my wive, but will accept them and allows calls.
I must add that I can text her when on wifi, and also from my mac, but when on 4g?
Any ideas?

Ios 6.0.1 battery drain iphone 4s

ios 6.0.1 iphone 4s battery drain on call,wifi,standby
i ithink ios 5 was batter thn ios 6 in this battery issue i jast want to know there is any solution???

This Apple page has tons of tips for improving battery life -> Apple - Batteries - iPhone

All iOS camera apps heavy battery drain why?

all camera apps on my iPhone 5 cause severe battery drain. Why?

The battery drain on the iPhone due to the iOS 8 is currently a trending issue which APPLE claims to be working on right now for the next upcoming update.
Agreed to the fact as the iPhone 5 is compatible to 4G Network due to which the Disable 3G option has been removed from the Cellular Settings.
You may use some of the below tips to work on the Battery Life:
1. Use of DND mode the most when possible maybe in the night time or when in a meeting,
2. A new option available in PRIVACY > LOCATION SETTTINGS > When Using, Always, Never.
Switch some application to NEVER which you do not use.
3. Switch the Display and Brightness to AUTO BRIGHTNESS,
4. Turn OFF the Bluetooth and WiFi option when not needed,
5. Turn the REQUIRE PASSCODE duration to the lowest option i.e. After 1 Min,
6. If possible use a DARK BLACK wallpaper,
7. In the MAIL Setting, turn OFF the FETCH Setting by selecting MANUALLY.
Let me know if you have already used these settings and still facing issues..!!

IOS 4.3.1 battery drain on iPhone

I have been wrestling with trying to find out what is causing my faster than normal battery drain issues since upgrading to 4.3.1 on iPhone. I thought I had it nailed when I discovered Skype was running in background. I have since deleted the Skype app but am still getting faster than normal battery drain. I then began to look at the internal processes running and am now wondering if any of those are the culprit.
How do you know what the process is used for and if it is needed? And then how to kill it?
Thanks and I look forward to your reply.

Well I'm still testing, but so far still looks crap to me.
It seems the opening animation is still horrible, but on most apps the second time you open an app (if it is already loaded) its smooth. This tells me when you first hit an app that it's loading is interfering with the animation. (never did this before 4.3)
The ipod app is still glitchy animation wise, and settings still has a second or so pause before appearing.
The camera app openeing speed seems to have improved a little though, but the double tap to reveal background tasks is totally inconsistant. (pause before doing anything, then glitchy crappy animation on screen move up).
Ultimately, I think that this is just a case of apple dumping the 3gs, and 'pushing' people to get a more powerful iphone (4 or even 5 later this year). The update doesn't even mention 3gs stability in the release notes, so Apple either basically have their head in the sand, or as I expect, just don't give a crap.
Will test some more, but this isn't looking good.

Iphone 6 Battery Drain Bug (Found ?)

I have a iphone 6 - 128gb model with T-Mobile as the carrier. To put it nicely the battery life of my iphone is PATHETIC!!!!! After turning the nice screen to 50% brightness and disabling about every feature I paid for on this phone here is what I get: With the phone turned on and the home page sitting idle - wi-fi on, my phone will drop 14-16% in 20 minutes. I can literally watch it go down 1% in little over a minute. I have spent hours reset from new etc.. and it still has the issue so I am going to go to the Apple store and demand a replacement.
Anyhow, in trying to find the source of the problem I discovered what MY biggest source of the battery drain. It is the "Wi-fi calling" feature. It does not have to be being used it kills my battery even at idle.. Turned off I may still loose 3-5% in 20 minutes but FAR, FAR less. Also my phone does not heat up with this disabled.
I posted this in case anyone else is experiencing the same issue, and needs a phone that they can actually unplug from the charger.

I found another thread here that discovered that the phone drops the wi-fi calling when the phone is asleep, so that is why it takes a few seconds to appear after you awake the phone.
Wi-Fi and Apples wi-fi drivers are broken. If anyone is having this same issue just turn your wifi calling off and see if it clears up the problem. Type "G" routers are another problem as well.
If this is you don't waste your time listening to the Geniuses and re installing everything on your phone as "new" it does not help. remember these are the same Geniuses that told you all you had to do when upgrading was to restore your phone from backup and it would be the same as new.

How to fix the ios 6 download. Battery draining problems

how do you fix battery draining issues after installing the 6.0.1 software

Search the forums, there are hundreds of thousands of postings on battery issues.

IOS 5.0.1 Battery Drain Fix

I need to say at the outset that I didn't have an issue with battery drain UNTIL I did the update.
I did the update using Software Update on the phone. It measured 55 megs. Update went fine but noticed within the hour that the battery was draining quickly. I tried restarting the phone and the battery percentage went UP from 95 - 97 %. Strange.
Overnight I noticed a drop of 7%. I tried to retrieve the full update from iTunes but was unable to because it already had the update. So I called Apple and was told to force the phone into Recovery Mode by holding the Home button while plugging the phone into the computer. This forces the update.
If you back up prior to this you can just restore the phone from that backup and save yourself some time .
Now, 3 1/2 hours later, with light usage, the percentage hasn't gone down at all.
If you've done the update, and continue to have these issues, you might want to try this as a solution. It is Apple sanctioned as their first tier solution.

About all that can be suggested is to use the feedback form and talk to Apple. They have communicated with some users, trying to get more info to find out just what the battery drain is so they can fix it. Unfortunately with the myriad of operating systems, apps and individual tweaks, there could be several combinations of settings that are draining the battery.
My personal suspicion is that it has something to do with iCloud and the wifi syncing. (My ipad, before I changed the setting, was reaching out to find a sync on a regular basis. And it may still be doing so, however I set my iTunes to not automatically open to keep my device from trying to sync several times in an evening...not to mention the constant aggravation of iTunes opening regularly)
That said, I could be wrong and it could be an app that users have in common, or several apps.

IPhone 5S with iOS 8.0.2 battery draining rapidly

I have an iPhone 5S with 8.0.2 recently installed on it. Normally, I can go a whole day and have the battery around 50 - 60% when I put it back to charge it at night. However, lately, the battery has been draining so fast that it doesn't last an entire day anymore. My usage has not changed. If I look up the battery drainage for the last 4 hours, the major players are Mail (28%), Home & Lock Screen (17%), and Facebook (13%). For the last 4 days, it has been Mail (41%), Home & Lock Screen (15%), and Safari and Facebook (11% each).
I had this problem with iOS 7.1.2, and I took it in to the Apple store and was instructed to delete and install Facebook again. I did this, and it didn't help. I then restored the phone and re-installed the back up. That worked until about a week after I installed iOS 8. I tried upgrading to 8.0.2, and the drain was faster if it changed at all. I tried restoring from the backup again, and this time it didn't help. My last option would be to restore as a new phone, but I'd like to avoid this if possible. It would take more time than I really want to spend on it.
My background refresh apps are limited to just a few. I also have the Mail program set not to notify me unless I get a message from a certain account or a VIP. I also limit what can use location services. Also, since mail was consuming the battery, I tried to decrease the frequency of retrieval, and even changed it to manual. Neither option helped the battery life.
I wonder if something is wrong in the OS that is causing this. Does anyone have an idea?

Hey David Ancell,
Thanks for the question, and great troubleshooting so far. You have already taken all of the most applicable steps: optimizing your settings, viewing which apps are using energy, and configuring your notifications. Because restoring the back up of your iPhone may restore the culprit causing these symptoms, restoring as new is your best option for isolation purposes:
iOS: How to back up your data and set up your device as a new device
http://support.apple.com/kb/HT4137
After erasing and setting up as a new device, your device is now in a factory configuration. Test to determine if erasing and setting up as a new device resolved the issue. Content on the device may have caused unexpected behavior.
If the issue is still present, you may want to contact Apple Support.
