Short battery, overheating

Hi i have the 13 inch mac book pro. I have had it for one year and just recently the battery life significantly reduced to 2 hours while just using microsoft word. just 2 days before i would be on it for 5 or 6 hours. also its seems to be overheating even though I'm just using word. I don't understand what could have caused this

Sounds like the battery is failing and I would err on the side of caution and remove it. Overheating is a definite sign there is something going wrong with a battery. And there is a possibility it could expand making it difficult to remove and cause other damage.
You might also want to post over in the Macbook Pro forums to see if anyone has similar problems or suggestions.

Has anyone encountered drastic shorter battery life both on iphone 5 and ipad since updating to iOS 6.1.2? How can this problem be solved?

Dear all,
I am new to this community even though I have been a Apple user for years, so please forgive me if this question is not in the right section.
Has anyone encountered drastic shorter battery life both on iphone 5 and ipad since updating to iOS 6.1.2? I've always been happy with these two products until the update - now the battery life is considerably shorter which is extremely frustrating.
How can this problem be solved? Is there any way to go back to the previous version?
Thanks for your help.

If you update using iTunes the phone is first wiped clean, then the new OS is installed, and finally the backup is restored. After this finishes if you sync your music should be restored. Music is not in the backup, because it is already on your computer and duplicating it would use up a lot of hard disk space.
An OTA update just patches what has changed; it does not disturb content.

Possible work-around for v3.0 short battery life

First: be aware there's a difference between "Push" (which is for some email account types & some MobileMe features) and "Push Notifications" (which is for apps). They are controlled in separate Settings screens.
Short story:
If you've upgraded to v3.0, usually have Wifi ON, and experiencing short battery life, and if you can live without Push Notifications (at least until Apple finds a better solution), TRY TURNING "Push Notifications" OFF.
Alternatively, if you can live without Wifi but need Push Notifications, try turning Wifi off & let the data travel via 3G.
Long story:
First I ran alternate days with Wifi ON, then Wifi OFF, and noticed with Wifi OFF my battery life was nowhere near as short (I could get through a day), but with Wifi ON, I can barely get through half a day. This is very different to v2.21, and in my setup the only significant difference was Push Notifications being ON.
Then today I've been running continuous pings from my Mac to my iPhone, with various combinations of Push on/off, Push Notifications on/off, email accounts on push / fetch / manual, and discovered there's a huge difference in how often Wifi gets turned on when Push Notifications is enabled.
With Push Notifications ON, while your iPhone 3G (and probably 3GS) is asleep, Wifi will be turned on for 15-20seconds every 1 to 2 minutes!
This is in stark contrast to Push Notifications OFF, but Push (for email, MobileMe, etc) ON, where Wifi is on only as often as your email account settings dictate.
This explains a lot, I think. With Wifi OFF, data goes through the 2G/3G radio, which is inherently ON all the time (for phone functionality), so the incremental 'cost' (to battery life) of Push Notifications is comparatively small.
But with Wifi enabled, data is instead sent via Wifi. The incremental cost (to battery life) is dramatically higher having to turn on the Wifi radio, find the WLAN, get an IP from DHCP, then exchange data with various Internet servers, when it happens every couple of minutes!
Though I'm not really sure what Apple can do about this situation. They appear to be turning Wifi on frequently to give the illusion of true (ie timely) push notifications. I think this situation runs parallel to those who found, with v2.x, that enabling Push on email accounts & Wifi enabled had similar major negative impact on battery life. Except now heaps more people want the Push Notification feature. Interesting conundrum...

The main thing that helped me with the short battery life was lowering the brightness. My 3G was so bright I could'nt sleep at night.

Serious problems including battery overheating

My dad and I both bought Revolutions and have had the same issues with our phones (listed below). We truly believe that the LG Revolution is a defective phone - what are the odds that we would both get "lemons"? While at the Verizon store on 3/13, the store, corporate customer service, and LG claimed to not be able to do anything for us except send us refurbished phones or return our phones to LG and have them worked on (HA. Seriously? Go without a phone? We don't have a land line anymore - might as well dump us on a deserted island). We were notified today, 3/15 that the phones were in the store ready to pick up, but they didn't come with new batteries! SERIOUSLY?!?! THE MAJOR ISSUE WITH BOTH IS THE BATTERY OVERHEATING! These phones are bound to either burn us or kill us. We don't want someone else's "fixed" phone, because it will just do the same thing! Unless Verizon will help us, I'm afraid we are going to get iPhones from another provider, as well as go to the BBB to file a formal complaint. I really don't want to, but I can't believe how much we have spent for our little death machines. We really hope Verizon will cooperate and uphold the standards they set forth in their employee handbook. We would love to be contacted by someone who can help. Please, don't give us the run-around. As anyone can see, factory resets, changing settings, etc. don't work. We have put up with those suggestions for months with no improvement.
My Dad's Revolution:
Bought LG Revolution ~July 3, 2011 for $250 + taxes & fees, car charger, (and eventually extra chargers). Over $300 total put in.
Battery gets overheated to the point that the phone is too hot to touch. This drains the battery from any percentage of battery to 0% in a matter of minutes. FIRE HAZARD IN YOUR POCKET! My dad's chest was almost burned! If it is too hot to touch on the outside, what is it doing to the guts of the phone?!
Not receiving text messages and picture messages that are sent
Internet doesn’t work properly - only when it feels like it
Loses data connection between 3G/4G/Wireless
Not always getting voice mail notifications
Phone burned up 2 wall chargers
Freezing
Phone is ringing, but the “answer call” screen doesn’t come up, so there is no way to answer the call
Phone rings once and then shows a missed call. When calling the person back, they say it rang the normal number of times before going to voicemail.
Not keeping a charge
Called sister next door and Dad could hear them, but she couldn't hear him. He called back and he could hear her fine, but she said he was very "scratchy" - keep in mind this is NEXT DOOR.
My Revolution:
Bought LG Revolution ~July 9, 2011 for $250 + taxes & fees, (eventually, multiple) car charger(s), insurance plan, (eventually, additional wall chargers) $400+ for the total cost
Battery gets overheated to the point that the phone is too hot to touch. This drains the battery from any percentage of battery to 0% in a matter of minutes. FIRE HAZARD IN YOUR POCKET! My thigh has almost been burned! If it is too hot to touch on the outside, what is it doing to the guts of the phone?!
Paying for “Unlimited Data” and phone constantly says “Mobile Network State: Disconnected”
Not receiving text messages and picture messages that are sent
Not being able to send text messages or picture messages
Getting the same text 3-4 times
Sending a text once and recipient getting it 3-4 times
Internet/apps don’t work due to no data
Loses data connection between 3G/4G/Wireless
Not always getting voice mail notifications – getting voice mails 14+ days late. This creates a serious problem for time sensitive messages.
Phone burned up 4 wall chargers and 2 car chargers
Freezing
Phone is ringing, but the “answer call” screen doesn’t come up, so there is no way to answer the call
Not keeping a charge. On a daily basis between 7:30am-12:30pm, I go from 100% to 20%. In the store on 3/13, the Verizon rep witnessed my phone go from 81% to 68% in about an hour
Phone rings once and then shows a missed call. When calling the person back, they say it rang the normal number of times before going to voicemail.
In the beginning, I would get email notifications and after I would read them, it would appear that they were “marked as read”, however, after I back out of the program, it notifies me of the same emails that I just read, only they’re once again “unread”. Now, I’m not getting ANY notifications of email except in the top drop-down screen, which if I click on it, I can see the emails, but after I back out, they disappear because the program decides not to work.
GPS is unreliable. It often says that I'm 2+ miles away from where I actually am.
The phone does what it wants to do when it wants to do it – not when you tell it to! All of our previous phones have given us reliable, clear service. What is wrong with this picture? HELP!!!

Hi I recently had the same problem with the LG Revolution. In fact it had been one of multiple replacement models that I had received in just a few weeks. The first two devices I had problems with them recycling power, I would make calls and they would make the same call multiple times i.e I would get through to the person I was intending on calling and the phone would call them on like a three way call asking me to merge the conversation I was only having with one other person... The 2nd replacement only lasted a few days. I was playing Words with Friends it gave me a sim error out of nowhere shut down. I checked the card after removing the battery and powered it back up. I was fine for about 10 minutes shut down and I was never able to turn it on again. The next phone they sent I received a few day ltr was the frosting on the cake. As soon as I tried to set it up the problems began. The phone was recycling power so much that it wouldn't fully power up before shutting down. Tech support insisted it had to be the battery, that there was no way they sent me 3 bad phones within 2 1/2 weeks... The new battery was sent over night. So I charged it up and gave it a go. It seemed fine at first, but then started acting up again. I resorted to it wasn't the battery and figured when I got to a land line or another line I would call Tech support. I was driving the phone was in my right lower scrub pocket apparently because of whatever mechanical defect it had overheated and burned me. I have been kind of at a loss when it comes to the Customer Service Dept. I have reported the incident to them even called to find out who to send my co pay bills too, no response. However they did have the nerve to send me a text asking for the device back or they were going to charge me $500. Now I'm thinking may be if people started taking things like this to the media they would act on it...

When I got a new iPhone5, I experienced short battery life, and system sofware issues were not the cause. The camera also takes a blury picture regardless of lighting and I have the black one. Has anyone else experienced similar problems?

What makes you so sure it isn't software?
The camera can be focused by take the point of focus on the touch screen.
If it is new as you said, it should be under warranty. Make a Genius Bar appointment or contact Apple with a repair request.

My MacBook Pro is really hot and the fan is on constantly. It didn't use to do this, does anyone know why this is happening? I have a very short battery life, so I have to keep it plugged in probably more than I should.

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

Still Having Problem with Battery Overheating with Car Dock/Charger when using Maps/Navigation

I'm having a problem with the battery overheating when using Google Navigation in the OEM Samsung car dock and car charger. On a trip last weekend, I started off with a fully charged battery (because posts on other sites have complained that the Charge cannot keep up with the power draw of the Google nav app while using the car charger). About an hour into my trip, I got a message that the battery was overheating and to unplug the charger which I did. I then had to contend with the screen going out because it was running on the battery. I let the phone discharge to about 70% then tried the car charger again. Within a few minutes, I got the same overheating message. It was not an overly hot day and the car A/C was set at 68 degrees.
This morning (with the battery at about 85%) I tried to use the Navigation without the car dock while charging and got the same results...the phone battery overheated and I had to unplug the charger. The battery temperature reached 116 degrees. (also, the battery level was also dropping while using the Maps or Nav application even though it was hooked up to the car charger).
I'm very disappointed with this situation since I was hoping I could replace my old Garmin GPS with the Charge. But between the phone dimming the screen while running on battery, and having a depleted battery in the phone at the end of the trip, its just not a viable option. I really like this phone, but I'm running against the "return" clock.
Any ideas?
Could this be a software problem that will be corrected by an update in the future?
fyi: other Charge problems in the last 5 days:
- dropping audio on calls to other Verizon phones.
- use of camera flash causing the phone to reboot.
(I do have the 'class 4' 32gb card in my Charge)
Thanks in advance,
Rich

Jerry:
Yes, the phone is charging while in the car dock. I confirmed it both under the "about phone-status-battery status" menu and by my battery widget. By watching the battery widget, I also noticed that the voltage steadily increased over the ride home. It started at about 3.90 volts and ended at 4.02 volts. I don't know if that is significant. This time the battery did not overheat. The Max temp was 110 degrees, but no notice to disconnect came up. This might be because the sun was behind me on the drive home rather than beating down on the dash like it was this weeked.
I've ordered a cheap universal dock from Amazon for about $15.00 which clips onto the a/c vent. I want to see if this keeps the temperature down. If this works, I can still return the fancy-schmantzy Samsung OEM car dock. (The car-dock interface wasn't that impressive anyway).
Please let me know if the volt change means anything.
And thanks again for your help!

Is it just me, or is anyone else experiencing shorter battery life for their iphon4 since the update to ios5?

Is it just me, or is anyone else experiencing shorter battery life for their iphon4 since the update to ios5?

Yes, I just switched from the 3GS to the 4S and My battery life is a lot shorter! wasn't sure if it is because it was trying to reload all my music or not

Iphone 5 VERY short battery life since 6.0.2 update.. Is there anything to change that? :/

Very short battery life on my iPhone 5 since 6.0.2 update. I got up this morning and it was only half an hour in use and it already lost 10% of battery life! Please fix that apple!

Apple is still signing for 6.0.1 so you can RESTORE BACK to 6.0.1. Just download the 6.0.1 IPSW for your device and then press the shift key while pressing restore (on windows) which will open a window. Select the downloaded IPSW and you'll be back on 6.0.1. And since Apple is still signing 6.0.1 THIS IS NOT A HACK
OR AN UNAUTHORIZED downgrade. So it DOES NOT void your warranty because Apple is allowing you to downgrade because they've allowed the 6.0.1 window to remain open. I did it for a friend's iPhone and it all worked out fine.

The cause of the whine, heating and short battery life.

It seems like we've discovered how we could fix the whine, heating and the short battery life.
If you take a look at /var/log/System.log
You will find this line:
localhost configd[37]: com.apple.SystemConfiguration.DynamicPowerStep load failed
Yes, that's right. Intel SpeedStep is not implemented in Mac OS X.
It seems like Apple wanted to implement it, either the engineer in charge of it was screwed up or apple was hurrying to get macbook pro released...
This also explains why Macbook pro has a higher battery life, runs cooler without whine on a properly configured Windows XP (with updated intel drivers and microsoft hotfix). On Windows XP, when the system is Idle, CPU is throttled to 1GHz.
So we have two options:
1. Get Apple to implement it correctly - but so far it doesnt seem like apple is really concerned about this issue. Or rather, they don't seem to care.
2. Implement it ourselves - A guy called Cryptonome was trying to implement the proper power management for MacBook Pros on Mac OS X to solve these "CPU whine", heating and battery life problems, and he did have some fruitful results, but it seems like he's currently too busy or something to finish the implementation.
Unfortunately I am not a genius so I cannot implement anything like this... anyone?
What do you guys think?

That's exactly what I am doing : expecting a solution from Apple. And you know what, Apple today released a new system update for the keyboard. This update is for all the MacTels including MacBook Pro. And guess the next thing... This update fix a power draw in the MacBook USB... Great... Oh, no, in fact not so great because this bug is THE bug that allows to stop the whine (through Mirror, etc)...
Is there anyone in Apple that tests fixes before to release them ? Do those engineers working on the whine fix have given a look to that patch ? I really hope that Apple is doing something, but releasing this Keyboard patch for MBP now can mean 3 things (IMHO) :
- the whine patch is on the final steps and will be released soon, so killing the workarounds for the whine is not a problem,
- or Apple has a partial (or even none) knowledge about this problem, and they should hire better engineers, because many people made a lot of discovers about this whine, not beeing engineers,
- or Apple definitly doesn't care about this whine problem, and they will loose myself as a customer (and probably others).

Short Battery Life and Very Slow Data on 4S

Short Battery Life and Very Slow Data on 4S,
anyone else noticing the slow speed of data on this phone?

Yes, I measure my slow data on Sprint in kpbs, not Mpbs. Like standard is download maybe 250kpbs, upload 100kpbs (that's 0.25 Mbps and 0.1 Mbps). On the same tower my buddy who has an AT&T iPhone 4 shows 2.5Mbps download and 1.5Mbps upload (that's 2500kbps and 1500kpbs), a LOT faster. Sprint has not been much help.

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.

Short battery life

hello
I have arch with gnome on my Toshiba laptop and i have very short battery life.
it ends after about 40min.
it seems to be problem in the system because when i open the computer it told me it have about 2hours and i put it on friend's laptop with vista and it told me i have 92% and 1:10hours left so i think there is(are) any or some process(es) that waste power and so short the battery life.
how can i manage the power consumption and by that to maximize battery life?
10x anyway

For starters, dim your display backlight. Set the system up to make it happen automatically. Have the shut the backlight off after more than a few minutes of inactivity.
Throttle your processor(s). Set up cpufreq and configure it to use an aggressive governor while operating on batteries. On laptops, you should also enable a governor such as "On demand" to help keep the system cool even when running on AC.
Don't do things that draw power. Try not to use the optical drive. If you want to watch movies, rip them to the hard disk while on AC, watch them from disk while on batteries, and delete them when you are done.
Look into the power management of your hard drive. You might look at allowing it to spin down when inactive, but I find this to not work real well under Linux. They tend to spin up and down a lot, negating the power savings.
See if you can shut things down. Wireless transmitters use a fair amount of power. So do the receivers while they are doing correlation (trying to synchronize to the chipping a spread spectrum channel). If you are not using wireless, shut it off. Look into whether your laptop can shut off other systems it is not using.
Minimize USB devices. They draw power from the system -- especially ipods and cellphones which charge their batteries from their host.
Laptop manufacturers spend a great amount of effort customizing certain operating systems from the American Pacific Northwest to maximize the battery performance of their systems. It can be expected that Linux require a little effort to optimize for power management as well.

Battery overheating hp pavilion dv2713tu

hi,my hp pavilion dv2713tu battery is overheating and lasts for very short time.....just one and half years had elapsed. is there any fault with the notebook ........i think i lost harddisc because of this only.........even hp service centere mumbai,dadar has charged me 7500rs for harddisc replacement.......is there any solutions for battery.......am loosing faith in brand hp now.......help me

get a new battery. You are potentially causing damage to the laptop by continuing to use it. The heat comes from excessive resistance to the flow of electricity i.e. a bad battery. 1.5 years is not a good life for a battery but not out of the normal range.
