4.3 upgrade issues - battery drain, unstable WiFi, freezing, wake-up lag/freeze

I've been (also) experiencing issues since my Galaxy S3 was pushed the 4.3 update on the morning of 1/11/2014. The worst is the battery drain - losing more than 50% of battery life within 4 hours of 100% with only minor texting during that time - with the charging process taking nearly 3 times longer to fully recharge. The moment it's removed from the power cord, it drops to 98%. This was not happening before update.
Today, I called Verizon's technical support who recommended a factory restore. Since I read endless posts/experiences of this not resolving the issues, I chose not to take that path and to work with Samsung to understand when a fix would be pushed. After 45 minutes on the phone with Samsung explaining the issues as if they'd never heard of such problems with the update - I was told that I clearly had water damage to my battery which was causing all of my issues. Sure, and everyone else who owns an S3 in these forums has the same water damage. Of course, the moment I asked to speak with the Samsung rep's superior, our phone connection grew dim, sputtered as if it were a bad mobile connection, and suddenly disconnected.
I experience the "Unstable Internet Connection" to WiFi when no other phones have issues with these networks. They're the same networks I've always used - but since the update, they're now "unstable".
The lag to wake up when I receive a call or text sometimes takes 10 swipes and a few freezes before it finally unlocks.
I've downloaded no new apps since the upgrade, yet apps I used regularly prior to the upgrade now randomly freeze on me, requiring me to remove the battery to restart the phone.
Unless Verizon is willing to let me out of the 2-year contract since I'm not able to use my phone in the manner to which we'd agreed in that contract, they had better start acknowledging a large-scale problem with this update and work dilligently with Samsung for a speedy resolution. Just seems odd that this update was pulled back in November for these exact issues, yet Verizon chose to allow it to be pushed to their S3 users in January without resolution from Samsung. Gee, wonder if it's so we'll all upgrade to the S5 as it's release is a few months off. Hmmmm.

I agree, the upgrade is awful. All I can do is complain publicly and if all of us do, maybe something will be done sooner.

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?

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 w/ Wifi

I have a 1st Gen iPod Touch and lately I have the problem if I turn on the Wifi and use Safari,Yahoo Messenger, or Youtube it drains the battery in less than 20 minutes. But if the Wifi is off the battery will last a long time (like hours). So what can I do to fix this ? PS my software version is 2.2.1 (5H11) if that helps.

using wifi will drain the battery. but it shouldnt drain it that quickly.
go through the trouble shooting steps. http://www.apple.com/support/ipodtouch/troubleshooting/ipodtouch/
if that doesnt fix it, take it/send it to apple.

Battery drain --My wifi vs another wifi

Question:
I have a 3 month old 3rd gen Touch that when connected to wifi at my house drains my full battery overnight. When I stay at my Gf's house and connected to her wifi the battery doesn't drain nearly as much (almost no drain). All Touch setting are the same and usuage is about the same in both locations. Recently updated to 4.0.
Any suggestions as to why one wifi will drain my battery more than another wifi?
Thanks...

Thanks for the response. I thought about that but in both houses the wireless router is less than 30 feet from the bed, and in my house only 1 wall seperates the bedroom from the office. Still stumped...

LENOVO K3 NOTE ISSUE-BATTERY DRAINING FAST AND USB PROBLEM!!!!!!!!

i have a problem in my K3 note, bought recently through flipkart..the phone was working fine but suddenly, now USB is not detected...whenever, i attach to the AC charger or charge with USB connected to laptop, it is neither getting charged nor USB is detected... But if i switch off the phone, now the phone gets charged... i have not been able to identify what the bug is about? i have factory resetted and also the battery was removed several times..however, the same problem is occuring.... Hope, i can get a solution from this portal Battery is also draining fast after this bug has started. Thanks in advance.

since many people reporting the heating issue.
i would like to ask you a favor to help me to do a experiment.
i am not sure if you guys know we have a feature called "background app management", it can restrict background tasks to block them consuming current drain. The heat could be generated by drain consumption.
the feature is at Settings->Power manager->Background app management.
I made a video shown at below link:

How should I tackle battery drain issues?? I'm fed up

I'm fed up a bit for my Z3 C battery life. This is my second query regarding battery life.
Does keeping Mobile data and Whatsapp running ON even in standby mode drains the battery??
I usually get just 1 or 2 whatsapp messages in an hour or two.
My phone settings-
Always turned off my wifi/ bt/ nfc/ gps/ location tracking/ autoupdates etc. & everything you can think and suggest.
I use only stock custom wallpaper and no live stuff. No widgets. No sd card inserted. With only two homescreens with just 2 shortcuts on each screen.
Have disabled apps which I dont use.
Stopped services of apps which are no longer needed.
No auto sync enabled for any app.
Display brightness is at 30% all times.
I use only these 3rd party apps-
Status bar mini
Network monitor mini
Whatsapp
Greenify
My daily Z3 routine-
At night while going to sleep I turn off mobile data, turn on airplane mode and turn on stamina mode. (12:30am - 9:30am)
Manually Force stop apps which are on. Use Greenify to exit/stop apps.
When I wake up the next day battery is down by 4-5%.
During day, phone runs in normal mode without any stamina activated. (10am - 12:30am)
The Low-battery mode seems useless as it does literally nothing.
Also, as soon as the battery is 100% charged and if I use phone for even 5 mins the battery immediately drops to 99%, so is this normal??
Even if I capture 5 photos in stock auto mode the battery drops by 1% or 2.
I reboot my phone once a week or in 10 days or when need arises.
Ram utilised is always 1gb. But I dont feel any slowness for any app or my phone usage.
So inspite of all this STRICT following what I get at the end of the day is just 1.2 days battery life.
Again I dont watch any movies or play games fearing my battery will deplete in no time.
So basically I'm using my Z3 as a battery monitoring unit and is 85% on standby mode. So when shall I use my phone the way it is designed for???
I have read people using it for occasionally playing games and watching movies, light surfing, calling and camear and it still lasts a good 2 days. So where I'm going wrong here?
I use 2G/edge network as 3G isnt available for my operator in the city I reside.
Charging the phone to 100% from 14% takes 3 to 3.5 hours.
I have already repaired my phone using Sony pc companion and also did a factory reset as well but this issue has been haunting me.
Sony center says the battery doesnt need any replacement as its still healthy and so is my device.
The phones service menu also reports battery status as Good.
I dont know when is Lollipop gonna be out for Z3 but I fear updating to Lollipop as it may pose more serious issues than doing any good apart from usual GUI tweaks & updates.
But just wish that lollipop brings in more relief to Z3 batteries and operations.

Hi all,
I dont know what topic to choose Got them all:
I was looking around and tried a lot of tips concerning the battery drainage, no luck ,
but then I noticed other issues as well
I tried to send a mail to support but, some how it is not working today: tried different browsers, even different computers.
NOT here to talk bad, complain or talk down on this product, I know the phone in working condition,
from my house mate and it is what they promise. I just dont know what to do and a bit frustrated and lauged at by my house mate.
I am posting, may be you guys have some answers, solutions or experiences.
But I think I am just unlucky to have a black sheep of the production.
My Firmware : 23.0.1.A.5.77
My issues.
- Battery Drain
- Screen isseus
- And reception issues
**Battery Drain**
I wake up 06:00 get it from the charger got to work when I come home 18:00 i got 15% left.
I actually can see the percentages going down while scrolling my emails.
ow beginning I work in support myself, I waited for an
- Waited for Updates
- Installed the update
- Un installed apps.
- Configured stamina almost so tight that most of the apps except email where online
- Did a factory reset twice
1) First time start using it as normal, with less apps, still same performance maybe
3% better, but that might be because i didn't used it so much of the less apps
2) Second time Factory reset - I got a 2, full days out of it:
- No Apps Installed
- No Wifi
- Didn't use it at al left it on my nightstand
- No data traffic
- 3/4 screenshots
- No Phone Calls
Well what is the use for a (premium) smartphone if you leave it on your nightstand?
When I start using it at the minimum installed:
- 2 email accounts (Gmail and company one)
- Facebook
- Spotify
Check it out:
!!This after the 2nd FACTORY RESET Yesterday!!!
Screenshot from this morning on my way to work
(to be fair left it with 100% unused at home and still 2 days and 3 hours)
Ok the next picture is on my way home , didnt use it since no apps installed and busy at work (this is about 12 hrs later)
Installed Spotify listened about 30minutes over 4g
18 hours left ? Quick calculation dat is 21 hours missing (33 hours in total)
Next installed facebook , some mail accounts, whatsapp, apped a couple of people that I am available again
45 Minutes later: 8 hours gone.
What do you think? Is it me? Or is there something wrong?
** SCREEN PROBLEMS **
I tought I noticed a couple of glitches with the screen, like little flashes,
but was not sure, I kind of found the use of the screen suspicious while monitoring the battery (50%)
al the time even if it was home doing nothing the whole day.
The the Bouncing touch, i experienced that also but not constant, there is another topic about that here.
Things I didnt worried about untill : I was looking around the battery menu,
and descover the usage graph screen, when I went in to it i noticed a little falsh and a lag.
and then I had a little heart attack: screen broken , dead pixels what is it.?! BUT ONLY on yhis screen,
no problem with it BEFORE the factory reset:
TAKE A LOOK, AND ALSO NOTICE THE GRAPH GOING DOWN ALMOST IN A STRAIGHT LINE,
screen shot a minute later as the 3rd screen shot of battery drain.
CHECK THE BOTTOM OF THE SCREEN , IT LOOKS CRACKED RIGHT? IT ISNT!!
** CONNECTION/RECEPTION PROBLEMS **
I kind of noticed , isseus , but wasnt bothered that much, only while analyzing the battery that was my main concern.
I noticed I had always less reception than others same room/place same provider (VODAFONE IRELAND),
maybe that was an factor draining the battery, but it was not like there was really low signal just one bar less then other
people an the other Z3 here in the house.
What did noticed , and I was willing to wait for an firmware update for it, It kept losing 4G connectivity;
it flipped to 3g for a bit and the stays hanging around H and Edge.
WORKAROUND restart the fone and with no problem back on 4g but after a while and not moving;
4g drops again to either H or Edge. (Mind Vodafone has the biggest and strongest 4g network at the moment here in Dublin)
So now I dont know what to do, I kinda bought the fone for my holiday (in 3 weeks).
- Is it serious enough that Sony will replace it? Since opening it up an closing it, will lose waterproofing
- What else will they expect from me to do / trouble shoot?
- How long will a solution take? Sending the fone back etc.
And finally other people reconize these isseus, and especially like me at the same time?
Thanks in advance For your Feedback (if Any).
I will try to mail support again now, and hope the website works now.

IPhone 5s battery drain fast with iOS 8.1.2

I have iPhone 5s from 1 year. After updating to 8.1.2 battery draining fast. I needs charge the battery 3-4 times a day. I did the restore as new, but no change. Stopping the apps does not help. Please for advice.

I have also experienced this, but I think I have started to narrow things down. First of all, I am on an iPhone 5S 32gb, and I did NOT have any of these battery issues under 8.1.1, but since upgrading, the battery drains more quickly for sure.
What I have noticed, however, is that there are some strange correlations going on with what appears to be ridiculously severe battery drain - my phone will show 50% battery, and minutes later (of normal use, taking photos, screen at about 50% brightness, no overt internet or GPS activity) it will suddenly shut down completely. This seems to happen most WHEN IT IS COLD and I am using it outside.
When I try to turn it back on right after, I get the "plug me in" screen, as one would expect with a dead phone. However, if I wait a few minutes and let the phone warm up a bit, I hold down the power switch and on it comes, and when it comes on, the battery indicator will show 50% battery life again. I think of this as my FALSE BATTERY DRAIN problem, possibly unrelated to the actual battery life. I have only noticed this happening while running the Camera or Safari apps. Looking at my usage doesn't seem to turn up any surprises.
So Apple... what the heck is going on here? Is this an OS problem, is it an issue with your apps, with app conflicts... what is going on?
This is unacceptable. You know after being an Apple user for 35 years now I am not going to switch to Android lightly, but this is pushing me that way, and it is certainly going to keep me from updating to a newer, shinier phone until you show some commitment to supporting your users, who seem to be experiencing battery issues rather frequently these days.
Please at least show some INTEREST in being involved in this solution... I'm not seeing any indications of effort to fix this.
Thank you.

IPod touch 5 battery drains very quickly even when not used

HI , I got a new iPod touch 5 for Christmas and let the battery drain before charging to 100%.
within a very short period of time and without using the iPod , (poss 2 - 3 hours ) the iPod was completly flat and would not even show the charging symbol. I charged it again and the same happened again , i did update the iPod during this time so it is currently running the latest iOS , I have tried a hard reset but still the battery drains very quickly without using the iPod at all. It is currently pretty useless as the battery life is so short !!!

BATTERY drain with 3.0

hi
has anybody same issue, battery drains since 3.0 like mad ?!
i stopped push, seems to help, but whatfore is push when battery drains so much ?!

Hi guys, just tossing in my 50c..
I too had the drainage issue. on my iphone 2g FW 3.0.1, with the update done and restore with backup.
drainage was 1 percentage in less than a minute, every minute and the phone was getting warm.
My settings where:
none of these settings turned on
-3g(obviously)
-push
-fetch
-notifications (cant see this settin any-hu)
-auto brightness
-wi-fi
-Bluetooth
But then i read about the restore as new phone and that seems to have done the trick for me.
usage statis as of now:
usage:1h 57
standby: 8h 24m
battery at 61%
last night i turned on ipod for 6 and ½ hours , battery went from ~85% to ~45%
Not bad, but i still think that we need a battery overhaul by apple as the phone (placebo?) felt to last longer on 2.1 firmware

My computer shuts down instead of sleeps when battery drains...

Hi there!
So, I just got a new MacBook Pro (the better 15" one) in June. I've noticed, however, that when my battery drains, and the little warning comes up that says "your computer will go to sleep in a few minutes to preserve data," if I let it run all the way out, it doesn't go to sleep but just shuts down. When I reopen my computer after plugging it in, all my stuff is back, but I do have to press the power button and start it up again.
My old computer (White MacBook 2006) always actually went to sleep, and only if I let it sleep for a long time did it shut off.
Have they changed the behavior? Do the laptops only shut down, and no longer sleep when the battery is gone? Or is something wrong with my computer. I'm getting all my data back, and all the windows and stuff are still open, so that's not a problem for me, but if my computer is working incorrectly only three months after buying it, then I'd like to know...
Thanks! Let me know what further information you need to help!

Your computer is not shutting down — it's hibernating, also called "safe sleep". This is indicated by the fact that everything you were working on is undisturbed when you wake it by pressing the power button.
The contents of RAM are written to the hard drive before the machine enters safe sleep, so that if the battery drains completely before you wake it, the contents of RAM (including your unsaved work) won't be completely lost. This is different from ordinary sleep, in which the machine simply suspends all activity without writing anything to disk. If the machine went into ordinary sleep after giving you a low-battery warning and not getting any cooperation from you (i.e. you didn't heed the warning and plug in AC power), and then you didn't wake it for twelve or fifteen hours, the battery might have gone completely dead and your unsaved work would be lost.
In short, yes, this is new behavior compared to several years ago, and from what you tell us, your machine is working exactly as it's supposed to.

WiFi loss & battery drain a software issue, not hardware

I wrote the commentary below after installing IOS 7 on a 4S and resultantly losing WiFi entirely and enduring major battery drain issues. After two trips to the Apple store and meeting with their techs at the "genius" bar, I was emphatically told that the issues were entirely hardware related and the only solution was to purchase a new phone. I was told there was nothing more to be done because the hardware was defective... either just use the not-so-smart phone as it is or buy a new smart one.
Well, here's an update on that story. I installed 7.0.4 last night and instantly my WiFi was back on and working. So far today, the battery seems to be back to normal as well, not draining like a giant hole in the levee. I don't know if this will be the same story for anyone else with similar problems. But I can say that the hardware-caused-storyline was bogus. Entirely time coincident with a software update (IOS 7), I lost WiFi and battery. And equally relative to the 7.0.4 update I immediately regained WiFi and battery.
I'm curious if others have experienced this same thing? And if Apple has an official explanation?
Oct 14, 2013 12:37 PM
I had a perfectly functioning iPhone 4S (64 GB) that I have been very   happy with and has always been glitch-free, good battery time, no   complaints. Until installing IOS 7.
Among other things, immediately upon "upgrading" to IOS 7 I have lost WiFi entirely (button greyed out).
Next, I found the battery drains to the point where I have to keep it   charging 2-3 times per day with extremely small phone usage. In a normal day, with 2-3 text messages, checking email 3-4 times and no phone calls, I am down to 30% battery by 3pm. Two days ago I turned airplane mode on at 9am with 98% battery and by 4pm batter was at 45% with airplane mode still on.
There are other problems, but those are the two primary issues.
I   went to the Apple store two times. The first time the technician   verified my problem, said there was nothing that could be done because   it's a hardware problem now and I would have to buy a new phone at full   price (my current cell contract isn't up until March 2014). He suggested a complete phone reset to "new phone" which I did and which solved nothing whatsoever. Same issues exist.
On my second trip to Apple just yesterday the technician looked it over, checked the battery function, etc. and I was told that the battery is fine but that the processor or something in the phone is working overtime and draining the battery. And again, I was told there is nothing Apple can do other than swap out the phone, though, this time they would replace it for $199.
I was tempted to pay the $199 for a new 4S that the technician said would come with IOS 6. But so far I have refused that offer without some assurance that future IOS upgrades wouldn't harm that phone as well. Also, if I paid this now, then I wouldn't upgrade when my contract ended with Verizon and I was looking forward to perhaps getting a 5S then. I know that it's impossible to assure that these upgrade issues won't happen again to the next phone, which finally leads me to my questions...
Considering   the options I've been given thus far, what would someone more in the   know suggest I do? Is there any possibility of a software fix or did the "upgraded" software probably ruin the hardware?
As   a longtime Apple fan and someone who has owned the first Mac laptop and early desktops, I don't understand why Apple doesn't have better   customer service policies regarding their own software directly   affecting their own hardware adversely.

I have the same problem with WiFi and off, the issue was Google Play services, this is what I did settings > apps > all > google play services > clear data > uninstall updates > restart the phone > update the app > check again .

I recently performed a upgrade from 7.0.5 to 7.0.6 and I found that my phone battery drain up very fast and the battery unable charge to 100. Besides, the battery live is going down when I charging with 3G on.Any solution for my issue? Please help.

Hi, I had my iPhone 4S and I'm recently upgraded it from 7.0.5 to 7.0.6 and I found the battery drain up very fast if compare to iOS 7.0.5. Besides, I also unable to fully charger my phone to 100% now - max is 85% with phone either in airplane mode or switch off totally
May seek help from your advise on above case.
Thank you
Best regards,

Try killing the battery (Let it drain---turning on all the settings, playing a video, and having the brightness up kills it faster), then let it fully charge from there. Let me know if that works.

Could Exchange be a cause of the battery drain issue with 3.1.2

I've never had a significant battery drain issue until I upgraded to 3.1.2. This started four days ago, when I've been relying on 3G more rather than WiFi since I've been out of town. I just changed my work e-mail Exchange from push to fetch every 15 minutes, and it seems to have improved some of the battery drain problems. I haven't done the experiment yet of switching back to push. Any other similar experiences out there?

There were reports some time ago of incorrectly configured Exchange servers sending out too many push messages, thus draining the battery faster than normal.

Is anyone having problems with the battery drains quickly and the iphone4 heats up in use and in charging after upgrading to 5.1.1?

Is anyone having problems with the battery drains quickly and the iphone4 heats up in use and in charging after upgrading to 5.1.1?

I have had the same problem but I seem to be getting somewhere to fixing it!!! My battery was going down at 20% an an hour now its 10% with constant use and 5 in standby !!! So improvement all round
First I did a restore then I drained the battery i started to charge it and when it came on I turned the phone off completely and let it charge to 100% I then left it for a couple of hours on charge at 100. I saw no improvement after 1st drain so I repeated the drain battery and charge steps again with the phone turned off when charging and have seen a very big improvement. I am going to do it again tonight and hopefully problem solved!!!!
The next issue is iMessage as that's playing up and wifi drop out
Good luck
