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

You can try resetting the SMC and NVRAM.

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.

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.

Battery life after installing iOS 4.0 on 3GS

I've read a little about loss of battery life on the 3GS after installing 4.0 so I was curious who else is experiencing these problems. Since installing the new software my phone is losing about 8-10% per hour when sitting idle. I am losing a full charge and using the phone less than 30 min. I have done a restore and have made sure aps are closed. I can;t get the phone to stop eating battery life. Any suggestions?? Please!

Bingo.....decided to try a restore factory settings through ITunes and then backed up with the phone settings so I did not lose all my stuff, if this had not worked I would have tried again but then reset as a new phone and start afresh, but thankfully I did not need to. Note you still end up with OS 4.0
After going through the set up and then recharging just once, the battery has performed pretty much as it is has done since initial purchase. In 16 hrs of minimal usage and in standby it has used 30%.
Good luck.

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.

Has anyone found a solution to the poor battery life in Mavericks?

Hi all,
I was wondering if anyone has found a reliable solution to the poor battery life after updating to Mavericks. I tried to have the Mac shutdown by letting it go all the way dead and then charge it back up but it still is lousy. To literally see the battery guage go down in such a short period of time is surprising as I didn't have this in my previous OS. My machine is a five month old Macbook Pro Retina. I want to say I started seeing this change after installing the last Mail update for Mavericks. I definitely didn't encounter it after the initial update to Mavericks.
Thoughts, comments, ideas?
Ed

Read through the posts on the right side of the page under 'More Like This'. Several fixes have been mentioned amongst them. But as there was an issue in Mountain Lion that was rectified with an update then it may just be a case of waiting to see if Apple issue a solar update for Mavericks. Remember it has only been out two weeks so I would doubt that if there is an update coming for it that they would release it without thorough testing.

HT4623 why am i experiencing short battey life after installing ios 7?

why am i experiencing short battey life with my IPad after installing ios 7 1 ?

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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 (2.5W, 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.

Take a look at this to make sure your settings are optimized to the best it can be.
If all else fails, try and restore through iTunes, set up as a new iPhone and manually sync your apps and media back to your iPhone.
If still persists after this, you might call Applecare and see if they can run a battery diagnogstics..

Which one of these phones has the best battery lif...

I am going to get a Nokia phone from "O2" store tomorrow. I will either get the Nokia 2700, Nokia 5130 or the Nokia 3120.
The dying Nokia that I am replacing I have had since 2005 and the battery usually lasted over a week between charges. The phone was an inexpensive one, €60 or something. I expect this kind of performance in my new phone.
Which of these phones have the best battery life?

I would vote for 5130 XpressMusic. 5130 and 2700 are on par in terms of battery life. Feature-wise, the former is a tad better. But, it's all about your preference, and the cost.

I just replaced my battery yesterday, but I am still getting the same battery life of about 2.5 hours. When I first got the laptop, I was getting atleast 6-7 hours.
Can anyone tell what is wrong? The stats are from the newly replaced battery

Hi katsoccer92,
The first thing I suggest you do is read neuroanatomist's excellent battery FAQ at http://discussions.apple.com/thread.jspa?threadID=1764220
New batteries can take a few cycles to work up to maximum capacity (and your figures indicate that the batteries maximum capacity is a little lower than you would expect, so maybe it still has some room for improvement).
In a situation like yours it is important to calibrate the battery when you first get it - see http://support.apple.com/kb/HT1490 I also often recalibrate again after the first week when the battery has settled down a bit, and then every couple of months thereafter. If your battery's full charge capacity isn't up around 4500mAh after a week then it may have been old stock or otherwise defective.
But usage patterns have a huge impact on charge life.
If , for example, you are watching a lot more "flash" based videos on line these days then you can expect a dramatic fall in computer run time. "Flash" plugins chew up a heap of CPU time, and accordingly can flatten your battery faster than a politician can break a promise!
Bluetooth is another real battery muncher, and so, of course, is anything like an external drive or other device powered by the computers USB or firewire ports (Elgato EyeTVs , unpowered hubs, bus powered scanners, etc etc). The internal iSight camera is a real power chomper too.

I have a ipad 4th gen with the lightning charging port. I have realised how long it takes to charge and the poor battery life which means I can't take my ipad anywhere. Is there a case that is available that will charge my ipad? I know they are out there

I have a ipad 4th gen with the lightning charging port. I have realised how long it takes to charge and the poor battery life which means I can't take my ipad anywhere. Is there a case that is available that will charge my ipad? I know they are out there for older iPads with the 30pin charger but I can't find one for the lighning 8pin charger.

I don't know what you mean by "poor battery life". If your iPad is working properly you should get 9-10 hours of life.

My Iphone 5 regularly goes dead with 30% battery life shown and when i plug it in it comes right back to 30% is this a flaw or can this be fixed

I had the same issue with mi iPhone 4S and now with my iPhone 5 sometimes. I think is software related but I couldn't find more info about it

My iPhone with 40 or so percent randomly shuts down with iOS 7 and 6. Often with the camera app stating the phone is out of battery. Moments later I turn it back on and the same battery life still appears.

My iPhone with 40 or so percent randomly shuts down with iOS 7 and 6. Often with the camera app stating the phone is out of battery. Moments later I turn it back on and the same battery life still appears. It sometimes happens over and over until I leave it alone for a while (still not charging), and then it works.

I think you might get a new phone instead of repairing it as it takes time and you said the repairing center is far from your living place

This wont even give me the right battery life for me.

My iPod video won't even give me the right battery life.. I charged it full. Then I start playing then in one hour its red.

When did you recieve the iPod?
You should be charging the iPod for about 2-4 hours.
The 5g 30gb iPod allows 14 hours of audio playback and 2 hours of video playback. The 60gb iPod allows 20 hours of audio playback and 3 hours of video playback.
The battery meter is just an estimate. It is not exact and it is wrong almost all of the time. To make it more accurate I suggest that you drain the battery and charge it back up.
