Update install leads to slow charge and battery drain

What's with the slow charge and fast battery drain after the update install?

I did a factory reset 2 Apr, the phone battery seems to be back to normal, but I guess time will tell. I still haven’t tested all functions but for the most part the S5 is back.

Iphone 5s getting hot while charging and battery draining

Hi
My new iphine 5s heating while charging and battery tetting draining very soon. Anyone can say why

Anyone having same problem? I phone 4 after updating to Vers.5.1.1. battery cannot be 100% full charge, always stop at 99% and battery drains off fast too :(

I had major issues with the iPhone 4s battery, however it’s resolved.
The tech who set the phone up at the Apple store did so with little training.
if you have a mobile me account. First go and move all your data to the cloud by going on your computer and logging in at me.com/move. The cloud has replaced mobile me, so there is no need for those two accounts
Also make sure that for any of your email accounts you set them up to fetch, not push. My tech person set them all to have the email servers push data to the phone. The new iphone4s antenna is extremely strong so it will continually try to access stuff that is pushed–***** a lot of battery life doing this. It makes it worse if you have exchange 2010 accounts. Something about changes made to exchange really suck battery life from devices that access such accounts.
turning of locator and the push notifications from facebook--they have a lot!

First off, i think it's sad that i have to use my non apple device to post this question... Why has my iPad become absolutely useless after updating to iOS 8.1? I am unable to use my mini because it crashes, slow performance, major battery drain.

Restore iPad to Factory Default; do not restore from backup. It may be the cause of the problem.
Settings>General>Reset>Erase all content and settings

I am not able to update any apps, when I tap on update, installing, appears for a second and 'update' appears again.

On my iphone5 , When I tap on update, installing, appears for a second and update appears
Again and it does not updates, this happens on my ipad2 and iPhone 3 also.

Settings>General>Software Update is currently only available for IOS 5 and above.
If your are using IOS 4, you need to connect to iTune (computer) to update software

My daughter has had her Razr for about 9 months now. About two weeks ago she picked up her phone in the morning on her way to school when she noticed two cracks, both starting at the camera lens. One goes completely to the bottom and the other goes sharply to the side. She has never dropped it and me and my husband went over it with a fine tooth comb. We looked under a magnifying glass and could no find any reason for the glass to crack. Not one ding, scratch or bang. Our daughter really takes good care of her stuff, but we still wanted to make sure before we sent it in for repairs. Well we did and we got a reply from Motorola with a picture of the cracks saying this was customer abuse and that it is not covered under warranty. Even though they did not find any physical damage to back it up. Well I e-mailed them back and told them I did a little research and found pages of people having the same problems. Well I did not hear from them until I received a notice from Fed Ex that they were sending the phone back. NOT FIXED!!! I went to look up why and guess what there is no case open any more for the phone. It has been wiped clean. I put in the RMA # it comes back not found, I put in the ID #, the SN# and all comes back not found. Yet a day earlier all the info was there. I know there is a lot more people like me and all of you, but they just don't want to be bothered so they pay to have it fix, just to have it do it again. Unless they have found the problem and only fixing it on a customer pay only set up. I am furious and will not be recommending this phone to anyone. And to think I was considering this phone for my next up grade! NOT!!!!

Is it ok to keep the power always connected on a macbook even though the battery is fully charged and battery sign shows power cable symbol?

Data usage and battery drain has skyrocketed with iOS 8.1.2 (maybe earlier)

3 weeks ago my wife got a text message on her iPhone 5 from AT&T that she had used 90% of her data for the month. 30 seconds later, she got another one saying that she had used 100%. Granted, her data plan is small, 200 MB. But, for the last two years she has used as little as 17 MB in a month and her largest prior to this latest month was 49 mb. This month she got to 380 mb before we were able to shut off her cell data. Otherwise, a second chunk of 200 MB and another $15 would have been added to the month.
We had noticed that her battery had been draining rather rapidly in standby mode with no background apps running when she didn't have access to WiFi. We have now correlated the two results, High Cell data usage, Quick battery drain and very warm phone. In case anyone is wondering about her iPhone 5 being one in the recall, it is. I took it in and had it tested. Apple says the battery is fine. It does hold a charge well. When all network communications are shut down on her phone and it is in standby mode, there is no noticeable loss of charge in 24 hours (our longest test).
Since I have a grandfathered Unlimited Data Plan with AT&T, I have been doing some testing on my iPhone 5s. Sure enough, I've seen similar results. With nearly everything turned off except Cell Data, I've seen 483 MB used in 24 hours. Of that total, 479 MB was used for Documents & Sync. I even have everything turned off in my iCloud account, Location services are turned off, no push notifications etc...
The best I can figure, this has been a problem since we installed 8.1.2 and yesterday I installed 8.1.3 resulting in no positive effect on this issue.
At this rate of data usage and no access to WiFi, my wife would have to have a 15 Gb data plan to keep from exceeding her limit. I don't think AT&T even offers one that big anymore. I might have to switch to Sprint or T-Mobile if this doesn't get resolved.
Any ideas would be greatly appreciated. Thanks in advance for your shared insights.

Hey this is Brian, bjmcmurry, under a different user ID. If I logged in as bmcmurry, original post, I was just getting a server error and couldn't get to this discussion nor post a comment anywhere.
Anyway, let me be as brief as I can. After an extensive analysis of replicating the problem on another phone to eliminate it being a hardware specific issue and that the test phone has an unlimited data plan, I was able to stop the excessive data usage and consequential battery drain. I believe I have a reasonable explanation of the problem, an iOS logic bug.
I had everything under my control clamped down on the test phone to minimize data usage. Also, I was forcing all data usage to use the cell towers. I determined that I was burning at least 11 to 13 Mb per hour doing nothing important. I literally had everything turned off except 'Settings' was allowed to use Cell data providing a avenue to log into the Apple ID.
The two phones had 2 things in common, they were using the same Apple ID and the same version of the OS. One was a iPhone 5 and the other was a 5s.
Here is a synopsis of my experience via my written evaluation of the Apple support system (Apple Rep name's have been removed):
After a couple of hours on the phone with an Apple Care Senior support Analyst, it was suggested that I go to the Apple Store to 1) get my battery replace in the iPhone 5 since it qualified for the replacement program and 2) see if the Genius could provide me with any insight in the data usage issue and battery drain.
I'm certainly glad I had multiple reasons to visit the closest Apple store, a 45 min drive. I got the battery replaced, thanks for that.
Regarding the important issue to me that brought me to the Genius Bar, excessive Cell data usage, I thought the Genius did a wonderful job listening and documenting the problem we were experiencing. Unfortunately, educating us on the use of the product or replacing our phone was not going to solve the problem. He eventually figured it out, this was not a user error or broken hardware. We surmised that the reason I was sent to him was to verify and document that there was a problem. I clearly had a problem. After writing copious notes on the issue, The Genius smartly referred me back the the AppleCare Senior Advisor. So, back to AppleCare Senior Analyst I went. She, knowing this was not a simple problem to solve i.e. beyond her level of expertise, got an Apple Software engineer involved.
My primary frustration is that this should have been escalated to software engineering right away. My trip to see the Genius was, I believe, a waste of time for both me and Apple regarding this issue. Diagnosis of this type of problem is well beyond the Genius’ knowledge and job. The Genius did a very good job doing what he could within the scope of his job. He just couldn’t solve this problem and had no one within Apple to which he had access for help.
However, that initial consult with the engineer was a bit feeble. Not only could I not talk to him/her directly, his/her focus was still working with the ‘Black Box' approach. Having Analyst ask me to do stuff like restore the Phone was more like trying to find a 'work around' than 'identifying the real problem.' Maybe restoring the phone was going to fix some corrupted data on the phone sidesteping the real problem, the handling of this condition. The engineer did listen to the fact that I had restored the test phone, the 5s, and only added the use of my Apple ID. Duh, been there!!!
Having been an previous owner of a software development company that I started in 1980 and retired in 2001, I can tell you that using the 'Black Box' method of debugging is extremely inefficient. Instead, having access to an ‘Activity Manager’ type app to identify in real time what process was blowing up the data flow would have saved me a lost afternoon at the Apple store and hours on the phone with tech support.
Ironically, I may have stumbled onto a "work around" solution short of turning off Cell Data that stopped the excessive Cell Data usage and consequential battery drain. Just prior to leaving the Apple Store, I used one of their Macs to log in my Apple ID on the id.apple.com website to ‘Manage my Apple ID’, I was forced to upgrade the security level of my password. Afterward, my cell data usage seemed to drop dramatically.
I told the AppleCare Senior Analyst that I may have stumbled onto a workaround and I suggested that I give it a couple of days of monitoring. We'd talk then and I would have results to report. She agreed.
Sure enough, my Document & Sync usage was back to normal, about 1/2 Mb per day. Am I happy that the excessive Cell Data usage has stopped? You bet! But, there was no intuitive reason that an end user would know to log in on the ID website to unknowingly solve this problem. As I use to say to my employees, that is not the ‘Macintosh Way.’ And, rebooting the the 'Microsoft Way.'
When I reported my findings to the Analyst, we both concluded that data usage was back to normal. She did report to me that the engineer did provide a laundry list of suggested activities to help solve the problem. Remarkably, they were everything that I had already done and were pretty much what the Analyst and the Genius tried to do. All reasonable tasks. But clearly, the engineer hadn't even ready the notes on the case before responding. And, none of the things suggested would have uncovered the real problem, likely a logic bug in iOS.
My advice now is to have the software engineering team rule out that there was an unresolvable state that a background process was fiercely trying to handle. The iOS does not seem to know how to intervene and prompt the user with a requirement to upgrade their password. If this does end up being the case, I would call it a logic bug, a perpetual exception that is not being handled properly.
Anyway, I hope this helps you.

IPhone 5 Continued Problems - Unable to Sync and Battery Drain

It seems that my iPhone 5 went to crap after the last iOS 6.1.2 update.
Battery life took a turn for the worse. No consistency in usage and standby time and battery drain.
But now, for some reason and I don't know if it's iTunes, I have been unable to sync and back-up for two weeks now. After going through all the syncing steps, all 7, it kicks back and error message: "iTunes could not back up the iPhone "My Name" because an error occurred."
No error code. Nothing.
Any ideas what I can do to fix it?

I got a new iPhone 5 about 3 weeks ago. I notice that from time to time in my pocket it heats up high enough I can feel it trough the material, but not as to burn. I read in a post in this fuorum that this hapened for some iPhones after they updated to the new IOS either when is recharging or some blame it on heavy gaming. Mine was not recharging and no game apps open, just the usual iTunes, Messages and phone as usual when I carry it. It happens about every other day, I can feel it through my pocket and soeme times when I am holding it it is quite hot. After a couple of minutes it seem to cool off again. it just does not seem right. (Im posteing in different discussion to see where I get an answer before taking it to the geniuses )
PS: Dave049 I'll try your suggestion and try re-adjusting the SIM card . if it works I let you all know. thaks for the idea

Hot to touch and battery drained

Has anybody's Iphone5 is ever hot to touch and battery drained at the same time.

Hi there,
You may find the troubleshooting steps in the article below helpful.
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
-Griff W.

Slower response and battery not lasting.

My macbook pro is running slower at times and the fan is staying on. Are there any utilities I should run to clean it?

First, back up all data immediately unless you already have a current backup. If you can't back up, stop here. Do not take any of the steps below.
Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail | awk '/:/{$4=""; print}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Reset the System Management Controller.
Run Software Update. If there's a firmware update, install it.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the View menu or the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for User, System, and Idle at the bottom of the window.
Select the Memory tab. What value is shown in the bottom part of the window for Swap used?
Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in andWrites out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard by pressing the key combinationcommand-C. Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Question about full cycle charges and battery life

So I've had the new iPad since day 1 and absolutely love it, though recently I've noticed that my battery life doesn't seem to hold up as well as it has in the past. I've done three full cycle charges since getting it however during my latest one I accidently brought along my iPod wall charger and not the one that comes with the iPad. My iPad was fully discharged and I plugged it in assuming that in the 7 hour window I had that it would be fully charged within 5 hours, but this was not the case due to me having the wrong charger. After about 7 hrs of charging it was only at around 60-70% so I had to unplug it, bring it home, then plug it in once more using the correct charger. Probably a fairly obvious question but does this not count as a full cycle charge because I unplugged it? Should I perform another full cycle charge even though this most recent one was not even a week ago. I know you're supposed to completely discharge your battery as few times as possible so it worries me having to do it again so soon.
About battery life, I've noticed lately that my iPad battery seems to be depleting quicker than normal, and was hoping that perhaps this was caused by being overdue for a full-cycle charge which I may have flubbed as seen above. I'm aware of a majority of the little tips and tricks to prolong battery life however I'm not so knowledgeable on the "do's and don'ts" of charging the actual iPad so any information on that would be helpful. I should also note that unfortunately I accidently left by iPad in a hot car for a little over an hour and was tremendously devastated knowing what this can do to the battery, so could this be the main cause for a seemingly weaker battery?
Thanks for any feedback!

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Over heating and battery drain on iPhone 4 after iOS 7.1 update

I am facing heavy battery drain and overheating after updating my iPhone 4 to IOS 7.1
The battery discharges @ 1% for every minute - when not in use / idle. The handset stays uncomfortably warm. The background app refresh, location services, screen brightness etc have been switched off/kept to the minimum. Though there is significant improvement in responsiveness. There were no battery/overheating issues with iOS 7.0.6.
Have reset all settings, switched on/off, given a hard boot (power button + home button) but no use.
Suggestions to resolve this are welcome.

This is not a software issue!!!. Yes, it may cause by the software update.. I had the same issue with my Iphone5 after 7.1.. I went crazy .. seeing my battery draining 1% a minute without using it.. and it took more than 7 hours to charge completely. Worst my IPhone was out of warranty cant take it back to Apple to have it fixed.
Things already did -
I changed the battery
Restored the phone
Switched to setting basically nothing
Waited for 7.1.1 to come out and then update the phone
But none of these helped at all
So i rolled the last dice.. took my phone to a local technician (in Philippines). They said none of the above will resolve the issue.
What exactly went wrong was the - USB POWER MANAGEMENT CONTROLLER IC U2 was busted. Once this was replaced my phone worked just fine. in fact I was amazed with the results.
My phone charged 100% from 20% in less than 60 minutes.
Now my battery lasts for more than 15 hours ( i do not use mobile data only Wi-Fi)
So if your phone is out of warranty no harm in getting this part replaced. If within warranty you may get a replacement handset.
Now to what causes this as per the technician " Every update from apple tries to exclude accessories that are not certified, and you do get the pop up that this accessory may not be supported" continue to use the charger will fry the IC U2 .
Hope this Helps goodluck

Serious Battery Problem: Lack of Charge and Quick Drain

I have a 15" Macbook Pro purchased late July/early August 2008, model number A1260 and has its software completely updated. I use the computer every day and, aside from the occasional cycling after getting the battery charge down to 0%, charge the computer every night.
Recently, my battery seems to be dying a LOT quicker, with the worst case of me leaving my computer to fall asleep with "Better Energy Savings" settings activated at 72% charge and coming back after about 15 minutes of cooking to find that the computer had completely died. After plugging the computer in to a power source, it took 10 minutes for the charge to change from 0% to 1% and, after reaching around 18%, I unplugged the power source and plugged it back in, triggering a change in the battery monitor that made the 18% charge reading jump up to 81%.
According to the System Profiler, my Power statistics are as follows:
Charge Information:
Charge remaining (mAh): 3016
Fully charged: No
Charging: Yes
Full charge capacity (mAh): 3512
Health Information:
Cycle count: 564
Condition: Fair
Any ideas on what the problem might be or what I can do to solve it?

Cycle count: 564
That's over 2 years of charging once every day cycles that you accumulated in just a little over 1 year. Personally, I don't recommend taking the battery down to 0%; it sounds like you have been 'riding it hard'. Batteries don't last forever.
If you purchased AppleCare, you can see what Apple says; without AppleCare, there isn't much you can do but buy a new battery.
Note that: http://www.apple.com/batteries/notebooks.html says:
For Apple notebooks with removable batteries — such as previous generation MacBook and MacBook Pro computers — a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles.
You are well over that.

Only slow charging and none while sleeping

Hi! I have a 17" 1,67 MHz PB with a charging problem. The time to charge displayed in the menu bar can change from more than 10 hrs to several hundred. When the computer sleeps it doesn't charge at all, although the power adapter light is amber all the time.
I have noticed that the charging is depending on what I do on the computer. If I just leave the computer on, the charging goes to almost nothing less than 10 mA. When the screensaver starts the charging increases to more than 300 mA, but that is still very slow.
It seems like the fast charging is not working and only the trickle charge that should start at 80% works.
I have done all the usual stuff, reset PMU, tried different charger, new battery, but nothing have worked. I have run Tech Tool Pro, and no problem is reported. I don't have the Apple Hardware test CD, but what I have heard is that Tech Tool does the same tests or more, right or wrong?
As everything else works I can live with this problem, but if there is an easy fix I would be more than happy. Can the DC-in board be the problem or the logic board? Where is actually the circuits located that controls this stuff?
Thanks, Leif
PB 17" Mac OS X (10.4.9)

How long did it take to charge the battery ?
About 40 hours to 92%, then it stopped, although the charger did not turn to green. But the charging icon switched to a power plug icon on the menu bar. To this time should be added the time the computer was sleeping and not charging at all, despite the amber light was on.
Fresh batteries require some cycles before they reach
their full capacity. So I would consider this as
normal.
You may keep an eye about this and - if nothing
changes - ask the seller for a replacement (but you
should consider that +/- 5% are in an acceptable
range).
Ok.
Have you followed the instructions provided by Apple
to calibrate a new battery ? See
http://search.info.apple.com/?search=Go&lr=lang_en&kwo
rd=&type=&newstype=&q=calibrate%20battery
Yes, I did this, but as I said, the battery only went to 92% so the calibration was not fully completed.
I recorded the charging with MiniBattery Logger and you can see the graph here: http://www.lignell.net/charging.png
The red line is the amperage and the amber is current charge level. The steep parts of the curve is when the screen saver starts. The dotted line is when sleeping. The amber charging icons means the charging starts after a stop. At the end the charging starts and stops all the time. The big red negative spike at the end is when running on battery only. Green line means it is "fully" charged (92%).
I hope this clarifies my question a bit. I think a normal charging should take a few hours only, without interruptions. The charging current never goes above 400 mA, and it should be more than 1000 mA.
