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.

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.

What is the expected battery life of a macbook air?

What is the expected battery life in hours of a Macbook Air? I have a 2012 model and it is only about 1 1/2 hours.

Sometimes my iPad1 locks up and has the flat battery graphic after charging all night, but will not work until you disconnect the charger, then it reboots and the battery is fully charged and works normally

Sometimes my iPad1 locks up and has the flat battery graphic after charging all night, but will not work until you disconnect the charger, then it reboots and the battery is fully charged and works normally.
It has only happened for the last month or so
Also, sometimes it drops out of apps, ie facebook etc. just like you have hit the stop button

Who replaced the battery? If it wasn't Apple the replacement is probably bad also. Either that, or the logic board is bad.

What is the expected battery life for a battery in the MacBook Pro (Late 2007)?

I purchased a replacement battery from an Apple Retailer for my son's 17" MacBook Pro (Late 2007) in December 2009. Last week, he gets a "service battery" message and the battery won't hold a charge. Is this the best we can expect in terms of battery life? It was supposed to be an Apple Battery.

Has your son been calibrating the battery per the user manual schedule? Has he been using the computer properly? According to the user manual it states in part:"Do not operate your MacBook Pro on a pillow or other soft material, as the material can block the airflow vents. Never place anything over the keyboard when operating your MacBook Pro. Never push objects into the ventilation openings."
MacBook Pro: Care, Use, and Safety Information
"Do not place your MacBook Pro on your lap or other body surface for extended periods of time. Prolonged body contact can cause discomfort and potentially a burn."

I have the 13" Late 2011 Macbook Pro, What are the best Battery Life saver/increaser Techniques?

How can I prevent My battery from degrading or atleast make the degrading slower
Can Ya tell me the steps or things to do?
I use my Mac a lot, like 6-15 hours everyday.
Someone told me I should keep it plugged with decharging it fully once a week.
is it true?
Can anything else be done?

You can use it on battery almost full time. It will slowly discharge to about 95% on AC, but then recharge after dropping below 95%. This is to save the use of the recharge circuits.
You should use it on battery only down to 40% at least once per month. Running it to dead will shorten battery life, not help.
The battery is rated to 1000 cycles. Two recharges from 50% to full is 1 cycle, 3 recharges from 33% to 100% is 1 cycle, etc ...
If you plan to store it unused for 3 months, discharge the batery to 50%, then remove from the MBP to preent the battery going down to 0.

What is the average battery life supposed to be for the nano?

my battery lasts like 2-3 hours, which is way to short, how long does yours last?

Mine only lasted between 2 and 4 hours, but it was the way I used my nano. I search around a lot, use the backlight, skip songs and really do everything that is not good for battery life. What I finaly did was to put in a higher capacity battery. It really was not hard to do. My ipod nano was off warranty and I went ahead and did it and am so happy I did, I now get well over twice the life I used to and am very happy. My ipod video was still on warranty and I changed the battery to a higher capacity as well, because of the positive result from my nano. Go here to determin your real battery life and to see if it is in fact a bad battery. If it is and you are still under warranty then by all means take it to the apple store or go online for service.

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.
Cheers

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.

My battery life between charges on my ipad 1 has plummeted to about 2 hours. The guy at the genius bar suggested it might be an app (unfortunately I didn't have the device with me). Does anyone know of apps that cause heavy drains on power? Thanks!

The battery life between charges on my iPad has plummeted to about 2 hours. The guy at the genius bar said the charge should last about 10 hours and suggested it might be an app (unfortunately I didn't have the device with me and the nearest Apple Store to me is 2 hours away). Does anyone know of apps that cause heavy drains on power? It also does not charge when it is plugged into my MacBook while I am using the iPad but it does when I am not using the iPad. I mostly use the iPad to read e-mails, play Team Lava games, read books through iBooks or Kobo and the ABC Player. Any thoughts would be greatly appreciated! Thanks!

Restore is about the only option left, short reinstalling the whole thing as new.
Before you restore, go to I tunes and turn off automatic sync. Then plug the machine in. Upload any photos that you have taken with the pad into I photos, or where ever you keep your pictures. Then, in I tunes, transfer any purchases.
If any apps or purchased music get lost in the process, you can download them again for free.
You do not want to make a backup of what you have on the pad now. If you do, when you restore, you will simply recreate the same problem.
What you want to do is restore from a prior backup. Do that.
Then run the system status app and see what the CPU numbers look like. If they are ok, then you can start to re add apps until the problem shows up.
If this does not do it, then the last step is to set the pad up as new. Check the numbers, then add the apps and settings back one by one. While it is likely to be an app, it may be a setting somewhere.

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.

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.

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.

Optimizing iPhone battery life: Between charges and before replacement

FYI. An excellent iPhone battery care article by iPhoneAtlas.com:
Optimizing iPhone battery life: Between charges and before replacement
http://www.iphoneatlas.com/2007/07/09/optimizing-iphone-battery-life-between-cha rges-and-before-replacement/

OK, I agree that is a completely false statement. The rest of the article is pretty good.
If you assume a linear decrease in battery charge for each full cycle (which it really isn't, but much easier to model in a spreadsheet). Then 80% of original charge after 400 full cycles is approximately 0.8% loss in battery charge per full charge cycle (again this is a simplification, stay with me). This means that after 400 cycles, you are at approximately 80% of your original total charge level. As stated by Apple.
So, extrapolating that out to EOL (end of life) which Apple assumes to be 50% battery charge, it would take approximately 1,000 full charge cycles for your battery to be EOL (according to Apple). It would actually be slightly less than that since it won't be a linear function.
For me, that's 2 to 4 years of use depending on whether or not I continue using the iPhone as much as I have this first full week.

Satellite S2410-504: What is the best battery?

Hi All
I am a complete noob to this but hope that someone can help me out. I have a Toshiba Satellite but I am not sure what model - it says on the back it is s2410-504. Anyways I have had it for about 3 years and I think the battery is kaput since it only stays on for about 15 minutes if unplugged from mains, even when fully charged.
The battery life has always been a bit short. What is the best battery that I can get for my laptop and how long will it last on most energy saving option?

Hi Cedric,
Battery life is very much dependant on the type of applications that you run on the notebook. Generally speaking, applications which make use of the hard drive or the optical drive will use more battery power than those which are more CPU bound. This is purely because of the amount of power needed to drive the hard drive and optical drive.
In addition, the battery life can be extended to a degree by conditioning the battery as per the Toshiba recommendations, namely to allow the battery to fully discharge periodically and then fully recharging it. By contrast, never allowing the battery to discharge either by keeping the notebook permanently connected to the AC supply or by constantly topping it up when it is only partialy discharged will shorten the battery life.
In your case, if you only get 15 minutes use from your notebook when it is on a fully charged battery then I would definitely recommend a new battery, especially given that the old one is three years old.
As to battery performance, it is usually better to obtain a genuine Toshiba battery although other compatible brands can usually match the original in terms of performance. I would always be wary of batteries which are exceedingly cheap or from a dubious source.
regards,
