Verizon iPhone 4 Battery Draining issue (continued)

This is not a question or help topic but more of an announcement. Here's my story:
I preordered the phone on it's February 3rd date and recieved the phone on February 7th. I did as Apple instructs when you get a new idevice (drain the battery down till it dies then recharge it to 100%.) I did that and began to use it, and keep in mind this was not heavy usage at all. I didn't have any app store apps installed at all, I set all settings in the phone to the best configuration for battery saving (truning off push notifications, turning off location services for apps you do not need, no bluetooth, no VPN, brightness at 33%, ect.) Now I thought the battery was strange as I had made my first phone call on 100% battery and it was a 5 minute call. I kid you not I lost 10% battery from one phone call. I thought that was rediculous so I went into my local verizon store and had it replaced. I did the same as I did last time and let the battery drain till it died and filled it to 100%. Tried the phone out and still had the same issue. I went back in and got my 3rd iphone 4. Did the same steps as before and drained then filled it. Yet again, I still had troubles with 3 phones in a row. I cantacted apple and got in contact with an apple engineer named Andrew. He sent me a file that they created that monitors what all is being used by the battery and monitors background processes and applications. I let that run for 24 hours and sent the battery loggin file back to Andrew. They reviewed the log and gave me a call the next day. They told me they did find some very significant battery draining and advised me to go to the nearest apple store ASAP and have the phone checked out. I drove 2 hours to the nearest store for them to just tell me the phone is fine (yotta yotta yotta) and they did a hard reset and restore on the phone (which I could have done from home on my computer and save the gas they made me waste driving for a total of 4 hours!) I tried contacting Andrew agiain but Andrew did not reply to any email sent to him nor return my calls. I got the point that he didn't want to deal with me anymore so I then decided to go the Verizon route. I called Verizon tech support and was transferred to a teir 2 representative. I told her my story, how many replacements I had, and how bad the battery life was. I told how my grandmother has an iphone 4 and I sat down comparing the 2 (battery life wise) and she chewed me out saying things like, "How dare you compare AT&T and Verizon!" I didn't want to listen to her chewing me out so I hung up. The next day I gave apple a call once again and they told me things I had already heard several times so I hung up. I called Verizon back and they said ok let's send you a replacement phone. Well the replacement phone came and wouldn't ya know it? The phone still had the same problem and on top of that they only sent me a phone. No box, no headphones, no USB cable, no charger. I called Verizon about this and asked why they only sent me a phone and they said, "Well you get to keep the phone but we want the other things back. The box, headphones, charger, USB cable, ect." I told them no and that they could have their refurbished phone back. This phone was not even refurbished. the reason I kow that is because it had someone's name written in the phone and it was still on 4.2.5. Had it been refurbished they would have done a fresh restore and update as 4.2.5 was deemed obsolete. That was very insulting in my opinion. So I sent that back and contacted apple one last time. I asked what other options I had as I was stressed and did not want to hear the same things I have already heard. they said they could send me a new phone free of charge and have me send back my current phone. I agreed to give it one last shot but I am still not confident that this phone will be any different.
Now that's my story. Now let me go into a discussion. I have been doing my own litle "investigation on this phone to see what is making this phone drain so bad. I took a look at a report from iFixit.com and they revealed some pretty interesting things built into the Verizon iPhone. I am not going into detail about it but you can google it and see for yourself and read the article about the components. They built the phone with not only CDMA tech but also GSM. Now what purpose would that serve? Honestly? That is a big battery drainer right there. Secondly, they found that the phone contained a different model battery that was lighter and had less capacity than the GSM version of the iPhone 4. That's a second red flag. My mission right now is to get Apple's attention that these phones do indeed have aproblem and they need to be looked at because this just aint workin'. I have had several replacements done (all have the same issue), several thousands of people are reporting the same results with their battery on the web, and Apple chooses to ignore it. Something needs to be done and I encourage any Verizon iPhone user to take action and make this issue known. I have a website with contact information of people who work high up in the chain of Apple along with Scott Forstall's contact info. Go to http://idevicesupport.webs.com/apps/blog/show/6441029-update and find a contact you like and call it and deman that apple investigate these phones. We can get this issue resolved if we make it known. Don't be mean or nasty to them. They are very nice people but at the sametime don't let them talk over you. Make your voice heard. Thanks for listening guys. Take care. - Joe

Iphone 5 battery drain issue, a question to all tech gurus.A challenge to those who can figure out the problem!

Hi guys!
I bought an iPhone 5 approximately 18 months back (warranty over) and have been running into battery problems for the past 1 month
my phone drains about 10% per hour while on sleep mode (no usage at all other than picking up calls) ,hence it can normally last up to 8-10 hours on sleep mode alone.However,when the phone is being used,it can usually only last up to 1-2 hours.It usually feels slightly warm on touch on sleep mode but becomes a little hotter when using at prolonged periods,otherwise it works quite well externally.This in my opinion is not normal since I've been using this phone for the past year and i can kind of guess the normal battery lifespan of my phone.My current iPhone 5 version is 7.1.1 and is not jailbroken.
I have had my phone changed into a new one just last year due to the faulty sleep/wake function,FYI
Before you say anything,i would like to let you know that i come from Malaysia whereby there are no genius bars here and most are 3rd party support groups who are more or less not bothered to fix or diagnose my phone problem and are more likely to change my phone into a new refurbished phone instead (cost approximately 300USD),they are not even willing to touch my phone.Trust,me I've been to more than one official stores.
Hence I've devised a few ways of diagnosing the phone problem myself based on online tips and tutorials
1)Factory reset : ive backed up and restored the phone (factory reset) with a new account just to test if it is the fault of the software.This process was done about 6 times in total but with no progress
2)Ive tried every single software tweak suggested from the net - switch off data/off wifi/airplane mode/off icloud/off background refresh/resetting the phone etc..You name it,I've done it!
3)Ive also checked for evidence of decay from the current iPhone,which shows a design capacity of 1430 and full charge capacity of 1352,which is pretty good if ud asked me.
4)As for the usage and standby values,it is not equal.on full recharge it says stand by at more than 20-24 hours and usage time of 8 hours.However,in reality this values are never really achieved.
5)Every single app has been deleted FYI,there are only stock apps in my phone.
6)Finally i gave in and had given my phone to someone experienced to manually change my internal battery into a new one ( i was observing him and I'm quite sure that he hadn't damaged anything while fixing it ).But this does not improve the battery power one bit.
This leads me to believe that this might be a hardware issue other than the battery itself,i was wondering if anyone has ever encountered a case such as this one since i am truly unable to find a cause on why the battery is drained in this manner,I'm suspecting that my sleep button might be activated,but my phone is unable to sleep internally due to some unknown reason.
Any help would be greatly appreciated!
Thanks so much!

IPhone 5 battery drain issues!

I was wondering if 6 hours of light usage on 4g/wifi is normal for an iPhone 5. I noticed that when I make a 15 minute call, my battery dropped from 91% to 85%. Also, my battery only lasts about 6 hours total, with very light usage, only texting, web browsing, and a few Facebook/Instagram browsing sessions. I have tried everything. I reset the phone and set up as a new phone, I reset all settings, all of my settings are set to the lowest possible battery usage options such as brightness low, push for emails off, anything possible to get the best battery life I can, but it still drains at a large rate. Just typing this post out drained 3%, and im using wifi, if I were typing this using 4G, I would be down 6%. So to sum it up, I was wondering if anyone else has been getting battery usage similar to mine, or if you have any solutions to fix this. Thanks so much.

Hi
Your screen need glue it again in the plastic cover around that keep her down. Your battery need for sure replace this is very common problem for all iphone 5 . If you are under warranty you must ask apple for replace .

My own Battery Drain Issues on iPhone 5

Hello guys, I've just created an account here to share my many issues with iPhone 5.
Well, this wasn't my Apple's 1st product, as I've had Ipod touch 2g and 3g, as well as an iPhone 3g. But it's my first time experiencing crazy battery issues with an Apple product, wich is really sad and disappoint, since this is the MOST expensive cell phone in my country (Brazil).
It all started about a week after I bought my iPhone 5. One morning I was on the bus, going to work, and my iPhone had about 99% battery remaining. 1h20 later, when I arrived at work, I had about 80% battery, so I panicked.
Suddenly I realized I was a victim of the common i5 battery drain. I was loosing 1% battery each 3~5 minutes IN STAND BY. And my settings are the same as they've ever been: wi-fi off, 3G off, 4G off (since it's not available in Brazil), brightness on minimum, no weak cell phone coverage etc. So, I shouldn't be experiencing this at all.
After reading lots of threads around the web, I realized that the ONLY solution to this would RESET AND START YOUR IPHONE AS A NEW ONE. No backups, no deleting apps and data. Sometimes removing email accounts would work, but as I didn't use this stuff, restarting my phone seemed to be the solution.
So I did it and, apparently, my problems were solved. My phone has worked perfectly for 2+ months. And then I let it fully discharge - but it's was not the first time it' happened. After I recharged for 4h, I started loosing battery really fast again, so the battery drain have came back. It was so frustrating.
Then I sent my iphone to an authorized reseller and they manage to give me a new replacement phone. They've checked my old i5 and detected a battery issue. My charger and cable were also tested but they were ok.
Well, after the very first charge on my new phone - and I've set it up as a new phone - the battery drain started again. I couldn't believe it.
So now I'm waiting for my 3rd iphone 5 in 3 months...
PS: My original iPhone 5 was bought in the USA, and the replacement one came from Brazil. Both were running iOS 6.1.4 when the issues started.
After all that, here are my conclusions:
1) In normal conditions, with wi-fi, 3G and LTE off, you should expect your iPhone 5 to waste 1% of battery every 1h30~2h15 on STANDBY. This is based on my best iphone performance and on Apple's information: iPhone 5 should have 225h of battery time (in standby) at it's best. Since 100% = 225h, every 2h15min you should expect to "waste" 1% of battery, on standby.
Sometimes, overnight, your phone might have an even better battery life: my friend only lost 1% for about 8h/9h overnight. But this is just not common. Expect to loose about 2%~3% every night with all apps closed and no wifi/3G/LTE.
2) If you detect a battery drain, GO TO AN APPLE STORE/RESELLER RIGHT THE WAY. Don't even bother trying a reset, as I did, because it might solve the problem for a while, but it CAN come back. Go to the apple store and ask for a diagnostic of your phone and battery. It will save you a lot of time.
3) There are MANY causes to battery drains. The most common ones seem to be: 1- Push notifications/email related stuff -> Reset email, internet and settings. 2- Facebook app -> reinstall app. 3- Defective battery - go to apple store/genius and ask for a replacement phone.
4) If an iPhone comes from factory with battery issues, expect AT LEAST ONE other issue. My original phone's touch screen was unresponsive when charging on PC and connect to iTunes and my replacement phone's microphone was not working properly. So expect other defective parts
5) With my experience, I've realized I might have discovered A NEW CAUSE TO BATTERY DRAIN: A DEFECTIVE NANO-SIM CARD. Why? Well, because it's the only thing that I have used on both my iPhones (original and replacement ones). And it's the only thing thats has never been tested (both my charger and cable were tested on apple's reseller and were ok). And in my replacement phone, after I removed the SIM, I started loosing 1% battery every 1h20, when on stand by and with no wi-fi, 3G or LTE. So, if you have a battery issue CONSIDER THE SIM CARD TO BE THE PROBLEM.
Also, when my replacement phone was near any amplifier/pc speaker, it would make the amp make that "call or text incoming" sound. (to understand this, put your phone near an amplifier/speaker and ask for someone to call you). This makes me believe that the SIM card was, somehow, defective and making my phone receiving data (and I mean only telephone data, like related to calls and sms) when it shouldn't.
That's all my friends. If anyone has ever experienced this crazy issues, please try to help me. I'm getting a new sim card, iOS7 and my 3rd replacement phone and let's see if it works as it should.
Sorry for the MANY mistakes, my English is not good =\.
Cheers from Brazil!

Hi Folks,
iPhone & iPad2 battery drain issue SOLVED!!!!!
I had a serious battery drain problem on THREE devices using different iOS .... it was a simple fix and had certain characteristics that you may be able to relate to ......
Devices;     16GB iPhone 4 with IOS6
                  16GB iPhone 4S with iOS7.06
                  32G iPad2 with iOS7.04
On or about Feb. 28th all three devices started to drain the battery like crazy losing about 20%/hour on the iPhones and 10%/hour on the iPad2 .... After messing around with settings, browsing forums and looking at what was common between the three devices I concluded the problem was with a single Microsoft Outlook/Live/Hotmail email account in the iOS native mail app .... I deleted the email account on all three devices (along with other unrelated Microsoft accounts on each device) and did a hard reboot (hold HOME and top LOCK button simultaniously for about 10 seconds until the apple logo appeared).
I then re-created the common Microsoft Outlook/Live/Hotmail account on all three devices in the iOS native mail app ...... SUCCESS! Now all three devices are behaving normaly with respect to battery drain ......
Hopefully this will be useful to others in this thread ..........

Iphone 4s IOS 7.0.4 update battery drain issues

I hope this gets to apple in regards to the issue of the battery drain. I have been following several discussions for the past couple of weeks and everyone seems to have some type of idea on what the problem is. I'm not a service tech or gadget know all, but I have been performing several "Nonscientific" test to see what is draining my battery.
I have a 4s that has always had good battery life. It seemed to run consistent to what was detailed in the product specs. I would only need to charge it every other day on limited use or the next day with heavy use. After updating to the latest update (IOS 7.0.4), the battery would drain in less than a day on limited use which is a couple of text, couple of email checks, 3 to 4 phone calls at less than 10 minutes each - no internet searches or game play.
So, after reading everyones suggestions in the forums and trying them, the battery still drained just as fast, if not faster. I read a post somewhere regarding “Bluetooth” constantly searching. So, I saw mine was doing the same. Someone replied to that person that it should not be the issue, as it does not use much power to run its task. (I found they were wrong)
Here is my nonscientific test, but a good one. (for the record I had nothing on in the notification center, Do not disturb off, only thing on in Privacy - location services was google maps, Siri, Yelp, and Find my phone; iCcloud was off; background app refreash was off; email fetch data was off; everything else was off)
Day 1 - I fully charged my phone several hours, I unplugged it at night before going to bed, did a hard reset to make sure every app was off, and only opened the settings app and made sure the Bluetooth was onand searching. I checked my phone 6 hours later and saw the battery drained from 100% to 56% with no usage other than just being on and in sleep mode. That would mean it drained at 7.3333 % an hour. Some would say that acceptable. - Its not when there is no usage. The battery would die in 13 hours with no usage.
Day 2 - I repeated the test (as above), but turned off the bluetooth. I checked my phone 6 hours later and saw the battery did not drain at all. I started with a 100% and battery was still at a 100% with no usage other than just being on and in sleep mode. I opened a couple of apps and closed them to prevent them from running in the back ground and noticed I lost about 2% of charge after usinging it checking an app or 2. I put it back to sleep mode and checked it again in an hour and saw it only drained 3% down to 97%. Very acceptible.
Day 3 - I repeated the test, but during regular day hours with limited use of the phone (with bluetooth off). I was back to getting close to a normal battery drain I was experiencing prior to the update. I know that IOS 7.0.4 uses a little more battery power to run as it has different features and abilities, so the battery drain was not like it was before, but a lot better.
So, my experiment concluded to me that the new update is causing the bluetooth searching to run in the back ground continuously and causing the battery to drain unacceptably fast on my phone. This is a program issue that can be fixed by Apple. I find it unacceptable to have to control my bluetooth manually, as I never had to do it before and I shouldn't have to do it now. I hope Apple will fix it soon. I‘ve been a apple product person for years, and enjoy the products, but lately they have been not been satisfactory in the phone business. I have been playing with a samsung galaxy thats looking very promising, if apple doesn’t fix the issue everyone is having, they will loose business to competitors.
Please fix the issue!

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.

How can I fix the battery drain issue on my iPhone 5s? it started when an updated to iOS 8.2 and upgrading to iOS 8.3 still did not fix it.

Iphone 4 from sprint and battery drain issues

how many people out there bought a new iphone 4 from sprint and having the rapid battery drain issues? there is a big thread on the 4s but not as much on the 4 and im trying to decide if its best to just exchange it or try more fixes.

I have the same issue. I am with sprint. The battery goes down in 6 hours, mostly in standby and some emails. I can actualy see the battery meter going down every 30 sec when reading my mails. iCloud is disabled as also push notification. The phone gets also hot. This issue is completely stupid and remember, I had iPhones for the last 3 years. My last one was the 4. It is first time I have such a problem. My friends that have the 4S with AT&T do not have that problem. As a mater of fact, I compared today and mine goes down 50% faster. I will have to return it and switch to another provider.

Have iPhone 6 and have 8.1 now w/battery drain issues. Advised to reinstall 8.1 in iTunes. How???

I seemed to have much better batter life on my iPhone 6 while on 8.0.2. Upgraded to 8.1 and now having battery drain issues!! Installed over the air on wifi and all seemed to upgrade fine. I've read a fix may be to reinstall on iTunes. How do I now reinstall 8.1 on iTunes when I'm already running 8.1? Any suggestions?

In most cases the problems when switching to a new iOS version are (as I had with my switch from iOS6 > iOS7):
- rogue app process (app not updated yet to iOS8/8.1) check Settings > General > Usage > Battery usage in percentage to determine which app is using much more battery although you haven't used it at all or much.
- settings in e-mail receiving is changed
- background app refresh (turn it off if you do not need it)
- location services (look carefully which apps you want to use this feature)
- notifications (look carefully which apps you want to use this feature)
- Facebook app

How to fix iPhone 4S battery drain?

Usage: 4 Hours, 44 Minutes - NOT TRUE!
Standby: 7 Hours, 54 Minutes
Battery percentage: 20%
iPhone 4S, iOS 5.0.1

sajith5 wrote:
I have recently brought an iphone 4s and the battery is draining even without much use. please advice if any one is able to fix it with some patches or updates iOS 5.0.1
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 (till 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... not all, but most. 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 4s battery draining extremly fast

iphone 4s battery draining extremly fast, how annoying is that, Battery will be drain out within 12 hrs and I just usually watch 30 mins video (not using 3G/wifi) and 10mins on Phone .
I always turn off my Siri, Auto Detect Time Zone, 50% Brightness, NO background Apps are running and Mail is manually updated.
Does anyone facing the same problem?

Go to advanced and set icloud to manual I used to suffer from this because of icloud it was stuck in a loop and always draining the battery, try also resetting your network settings if it didn't work reset all settings and set it as a new phone drain the battery and charge it from 0 to 100% to recalibrate the battery , hope this works for you

Are battery drain issues fixed in 6.1.3?

I realize it only came out a few hours ago, but can anyone confirm if the Exchange bug that wasn't completely fixed in 6.1.2, and/or the iCloud Document Sync over cellular were fixed in 6.1.3?
Thanks!

Good evening all,
I too am an Apple Developer and have been messing with these devices for a while. I can attest that 6.0.1 was the most stable and efficient iOS v6 I used. I have a 4S and a 5, both ran 6.0.1 until the "exchange bug" was fixed. I am sorry I upgraded my 5, because I see significant battery drain issues with or without Exchange configured. I have restored from DFU, Reset All settings, turned on and off all settings, etc (every trick on the forums) I test and tune for a living and clients complain to me and ask for a fix, so I do the best I can. My 4S with the SAME configuration as my 5, lasts FOREVER! When a phone works perfect, and one "upgrades" software and sees problems, 100% is related to the software, not hardware. Unless the software is not compatible with the hardware, then I would make the safe bet and say the software is the culprit, def an Apple realted issue IMO.
The reason for Apple to change the software on devices is because it changes how the hardware functions. Without software, our hardware would be nothing more than paper weights. Working with software for years I know its hard to get it perfect for millions of users. Apple has their work cut out for them. I don't expect perfection, but it would be nice to build on a good foundation. I thought they finally turned the corner with 6.0.1 but 6.1.2 is a painful reality for people whom truly rely on their mobile devices. Have faith, because 6.1.3 from a restore from a "new phone" has been working smoother for myself..so far.
