Battery life after updating to 6.1.2

Whats going on with 6.1.2 update!!! My 4s was updated yesterday and the battery drains so fast, fully charged my phone twice today and its already dying now and it's getting hot too without realy using it.
Before updating it used to last me a day with normal usage.
Any ideas?

I updated my iOs to 6.1.2 last week and three days ago, I began to notice that the battery depletes VERY fast.
I woke up at 7am to find my battery fully charged & unplugged it. Slept for 3 more hours and found my battery at 47%. This never happened on my phone with previous updates and even on my iPhone 4s.
I already tried several suggested fixes written on the discussions and it won't seem to work. I "erase my iPhone", did a hard reset, removed my sim and it all don't fix it. Almost tried to illegally downgrade my iOs but I decided not to. Guess I'd just better wait in vain for Apple to fix it themselves with a more credible andreliable iOs update.
Anyone having the same problem?

Iphone 5 battery life after updating to ios 7.1

Has anyone else suffered rapid battery drain after updating to ios 7.1?

For users with battery drain problems also look at this message from me in another topic. Maybe it also helps you to find a solution to the drain problems on your iPhone. I would also suggest to read the complete blog post by a former Apple Genius bar person.

IPod Touch 5th gen suddenly has terrible battery life after updating to ios 8.0.2!

I updated to ios 8.0.2 around 2 weeks ago and bam! the next day I wake up and use my ipod (I usually leave it on during the night, and battery is still good) and it's down to 50%, then to 20% later! And now the battery is terrible! it goes down much faster than before! I have bluetooth and all the battery killer stuff off before, so my battery was really good...and now it's horrible!
Have you guys experienced this? Any solutions? Is this some bug?

I'm having battery issues after updating to OS 10.9.2. Anyone else?

I noticed that my 13 inch late-2011 MacBook Pro has seen a significant decrease in battery life after updating to OS 10.9.2. For example, I will turn off my wifi and just watch DVD's and the battery life isn't any where near what it used to be. It's only a few hours! This is awful. My brightness settings are down and I'm not connecting anything into the USB ports and I am not using wifi. Any ideas or anyone else experiencing similiar issues?
Thank you!

jrnet154,
have you tried resetting your MacBook Pro’s System Management Controller?

I Have been getting BAD battery life after the ICS UPDATE !! on the DROID RAZAR MAXX have this happen to any one else ??????

i have been getting really bad battery life after install ICS on my droid razar maxx i can only go 1 day and 3 hours where i used to be able to go 2 day easy have this happen to anyone else can someone tell me how i can make my battery life better??????/ and do i need to let my phone go complete dead before fully chargeing it again ??????
before install the ICS update i had 30 percent of battery life remaining so i pluged it in and let charged for a little bit while it updated my phone and ever thing after it updated i unplug my phone and started playing on my phone to see what ICS was all about but when it got to 15 and said " connect to your changer so i did !!!!! should i haved let my phone going complete dead since i unplug without it fully changer or does it matter ?????????????? if someone could please help me !!!!:)

What was your battery reading right after the update when you unplugged the phone? I have never let my Maxx drain further than 20% battery ever before I charge it. Yesterday after the update I also played more with the phone trying to learn the OS, as did most everyone on this forum. Give it a few days of your normal use before you decide your battery life has decreased. I took my phone off charger today at noon, it was 100%, and now it's 80%, with about 30 min talk time, and mostly standby. that's about normal batt life for me, maybe a little better than before the update. I'm still going to watch it for a few days before I make a conclusion about battery life.

Wireless driver triggers warm/hot macbook and low battery life after OS 10.8 mountain lion upgrade

Hello frustrated Macbook users.
I have tried to get help on other Apple discussions but no one seems to want to help, they aren't actually reading my posts, or they hate me for some reason.
No matter.
If you have a warm Macbook that has 2.5 hours of battery life where you used to have 4 or more, please do this simple procedure and write the result below.
Turn OFF Airport wireless networking
Perform an SMC reset (Power Manager)
Connect an ethernet cable and use your Macbook normally. (but do NOT turn on wireless networking again)
How is your battery life after doing this?
I have a user over here who reclaimed decent battery performance if he doesn't use his Airport wireless.
I need confirmation.
If so, I may get a USB wireless adapter and see if the battery life stays good.
Bonus points: If you have a Mac compatible USB wireless adapter and got good results by turning off the built-in adapter, want to test it for me and report the results?
Thanks and good luck!

UPDATE:
Problem persists when using Recovery Partition.
Chance sthat it is third party softwae or updates is more or less eliminated.
Update 10.8.3 beta fixed the problem for one lucky early adopter.
Hypothesis: New battery charging algorithms programmed into Mountain Lion OS10.8 triggered problems from design flaws that were NOT an issue for OS 10.7 and before.
Battery replacements were successful where the replacement battery was built within tolerances that did not fail under 10.8's new charging algorithms. Other bateries did not meet those tolerances so you would get spotty results from battery replacements. It worked sometimes, but not always.
OS 10.8.3 may have adjusted these algorithms to be less demanding on the features of the battery that were failing.
Official word from Apple is 'mum'.

HT1414 anyone noticing a decline in battery life after downloading ios7????

anyone noticing a decline in battery life after downloading ios7?

I have an iphone 5. Ios 7 is a disaster for battery life! It used to drain about 1% every two hours, 5% over night roughly (not being used). Now it is draining at double the rate. It drained 10% over night and it isn't even doing a thing. I think something is clocking up usage when it's idle.
Screen brightness is minimal.
Background app updating is restricted to one app which isn't running the majority of the time.
Dynamic wall paper and other stupid stuff is all turned off.
I can't turn off the stupid clock animation. I wonder if working out how that is displayed is the issue???
It shouldn't be draining at 1% per hour when not even being used.
Favourite locations is still switched on.
Is there any benefit in turning off wifi and using 3g data only? I had the issue before that having 3g enabled meant double the battery drain so I only used it when I was out.
Ipad mini seems fine though. Battery life is same as last ios6 ie about 14-16 hours use.
I now have caret running to find out what the rogue thing is. The majority of the time few apps are running at all.
My general average usage is 12-15% per day if lightly used and 25-45% if it is moderately used. Now the phone is draining at 25-33% a day when lightly used!
Beats me why an ipad mini which is advertised at up to 10 hours on wifi nearly doubles that and the iphone which is advertised at the same rarely reaches it. I usually get 8 hours of active use if I'm lucky. Now it's more like 5-6 which is hopeless.

Is there a fix yet for the loss of battery power after updating to Lion?

Is there a fix yet for the loss of battery power after updating to Lion? I've done the cmd-opt-shift restart and it didn't help. This problem has gone beyond annoying now - it is absolutely maddening! What is Apple's official response????

Chris: your friends are woefully uninformed, and no one should pay any attention to their bad advice.

how can i maximize my battery life after its been damaged?

Just like it had nevr been damaged; fully dischagre and charge monthly, minimize battery drain so you minimize charge/dischare cycles.

What is going on the my battery life, after installing Mavericks, what a drain!!!

What is going on the my battery life, after installing Mavericks, what a drain!!!

You can try resetting the SMC and NVRAM.

http://support.apple.com/kb/ht3964
You can also try running the short and/or extended Apple hardware test by holding D button while booting up and then following the instructions.
http://support.apple.com/kb/ht1509
If that doesn't work (seems not extremely likely that it will) you can backup and try reinstalling a fresh OS.
If that still doesn't work maybe the battery is bad. If you don't feel like messing with all that just take it to Apple. They should have a test they can perform.

Is it normal for iPhone 4S to lose 1% battery life after 2-3 minutes of using?

Is it normal for iPhone 4S to lose 1% battery life after 2-3 minutes of using? So in 2 hours, 24 minutes usage and 15 hours, 17 minutes in standby mode, the battery became 68%...

sounds plausable
also you can't really 100% trust it's batt% batteries are an analog technology the only thing the iphone can judge how much batt is left is by measuing amp amount the batt is producing and then over time estimating how long before it's zore
but anyway Its not wise to not put a battery for charge before bed when it's 12%
if your reason is you think it's good for batteries to be empty before charging then you believe in a myth and in the process damaging the battery in your ios device

Hot battery and short battery life after download of Mountain Lion.

Hot battery and short battery life after download of Mountain Lion. Any suggestions?

As in, shortly after install?
Note after you install Mountain Lion it's likely that the Spotlight index will be rebuilt. This will take some time and the machine will run hot. After this completes, which could take 1-2 hours, things should return more to normal.
If they don't, I suggest running Activity Monitor and seeing if you can trace what is eating up CPU cycles.

MBP 13" Aug09, lost 2 hours battery life after upgrading to SL

Hi, my Macbook Pro bought on Aug 09 lost 2 hours of battery life after an upgrade from Leopard to Snow Leopard.
I brought it to the Apple service center where they checked the battery and they said that the battery has no problem.
Then, they suggest me to format my mac and reinstall Snow Leopard on a clean disk which i did without any success.
So now, my battery still hold 100% of it's original capacity (over 5450mAh) but my battery died before 3 hours with 0 program running !? (it used to last over 5.5 hours while running Leopard)
What's the matter with my battery.
And of course, i tried all the calibration before i post this topic.
If anyone can help now, it would be so great ! can't expect anything from Apple as they consider my battery as new.
Thanks !

I too have been experiencing worse battery life.
I used to have about 3.5 hours on my now one year old Unibody MBP.
After SL (and switch from original 5400rpm to seagate momentus 7200rpm) I'm now down at about 2 hours.
Wifi enabled
Bluetooth enabled
Brightness around 80%
2 hours is very little compared to the promised 5 hours.
My battery stats:
Health: 94%
Cycles: 112
Full charge: 4344mAh
Feels like I'm on an old lousy PC laptop again.

Awful battery life after latest OTA update

I've owned my Bionic for about 16 months now, and up until recently, have been very pleased. After the initial Jelly Bean update, I was enjoying the best battery life I had ever experienced, up to 20+ hours with moderate use throughout the day. However, the latest over the air update (I remember hearing my phone restart itself after the update in the middle of the night), my battery life has suffered dramatically. At first, I thought the battery was bad, so I ordered a new one, but the problem persisted. I searched online and discovered others were experiencing similar issues after updates. I have tried various solutions, included wiping the cache, deleting apps one at a time to determine a culprit, and eventually even a FDR, but none have helped.
I am almost positive the issue is stemming from "wakelocks" and other things waking my phone up again and again, even with the display off. My battery will drain from 100% to 40% as I sleep at night, even with WIFI and data disabled. The battery stats show Android OS and/or Display (they alternate) as the leaders for my battery usage, usually around 40-50%, which is much higher than it used to be.
I have become increasingly frustrated with this issue, as there seems to be no known solution other than getting a new phone. I find it almost inexplicable that an update could go out that causes such problems. My phone has basically been rendered to a tethered device, as I can't go more than 8-10 hours without recharging. If there are any known solutions, or if I can possibly receive a new Bionic, please let me know.
Thanks.

After the Google logo appears and I try to go to step 5, I get the green
little robot on his back, 'tummy' open with a red triangle and exclamation
mark in it....and it stays there for a long time???
Then the phone reboots....problems stay.
I do not know who you are Kevin but I was at the Verizon store on Friday
and I was told to call customer service as they are not responsible for the
software...it's Samsung's problem!?
I am a +$300 a month client and this is the service I get!
I will close my account, pay whatever it takes and go someplace else if
this doesn't get fixed fast...this did not happen on my request and I'm
stuck with it.
