To MBA 2013 i5 users: What is the battery life?

Hey guys,
there are some hot discussions over battery life in MBA 2013 with i7. I personally own one and I can say that 12 hours is nothing close to the truth. Battery life can reach that long when WiFi is turned off, but web browsing is the most basic activity on a computer these days. My MBA gets around 7 hours of battery life when using Internet connection and I feel cheated by Apple.
I'm thinking of exchanging my model to i5 one, but haven't out whether battery life is significantly better or it's same kind of gimmick.

several reports indicate (from reputable testing sites) that 12 hours on the I5 13" are understated, and that 2 hardcore tests indicated just under 13 HOURS, or a hair OVER 13 hours
I have an I5 13", and I dont say with difficulty that batt. life is, in short, crazy / shockinginly fantastic.
My older 2011 Macbook Air i just sold, ......it literally blows my old AIR out of the water powerwise, and writing 1.1GIG Photoshop to the HD, was id say about 40% faster from full install between the 2. (old and new).
I run nonstop youtube (white noise) in the background.....(on firefox, which is a battery hog compared to Safari), and typing, and opening PDF files.........under those conditions, im getting about nearly 12 hours batt. life, of the 2 times ive actually clocked it.
Ive compared my I5 next to my friend Stefans I7 13", i did same same testing for 5 hours, and his was 28% LESS batt life

What should the battery life on my 13" Macbook air be?

I have a 13" macbook air (mid 2012) and the battery life is around 2.5 to 3 hours. I know after a while the strength of the battery diminishes but should i only be getting about 2.5 hours? I am still under apple care till 2015 should I have apple look at it and repair/replace battery? I know on the newer 13" models the battery is 12 hours (new processor and chips) but still shouldn't my battery last longer than 2.5 hours?

It should get a great dea; ,pre tjam 2 1/2 hours. First a question. Is this the actual amount of time you are getting or is it the estimate provided by the battery menulette icon? The estimate is often very wrong.
But assuming this is actual battery life, the first thing to do is run the Activity monitor, click on the CPU tab, and then click on the % CPU column so the little triangle is pointing down. This will give you a list of all the processes your computer is running and at the top of the list you'll see the ones that are taking up the most power. Also, if your Dock is hidden, temporarily unhide it. Now click and hold the mouse button on the Activity Monitor icon in the Dock. You'll get a little menu. Select Dock iCon and then CPU Usage. This icon will give you blue bars for each CPU core. Lots of blue means high CPU usage and lots of grey means low CPU usage.
As you use your computer keep an eye on the AM icon. If your battery problem is due to high CPU usage you'll see the bars in the AM icon showing lots of blue frequently. It may be due to the program(s) you are using. For example, VMWare and Windows 8 are battery killers. So are 3D games. But if you are word processing, checking email, etc you shouldn't see more than a glimmer of blue most of the time.
If it turns out you don't have high CPU useage the problem could be the battery and that means a trip to the Apple store.

Mid-2013 Macbook Air: question about the battery life

First of all, I'm sorry if these questions have been already asked, I've looked around and I've seen some answers, but none that fit my specific case.
I have had this computer since December (Macbook Air, 13'', Mid-2013), I've been using it for a month now. At the beginning, I used to use it until my battery was low (between 10 and 20%) and then charge it. Then I learnt that it's better to keep it plugged as much as possible (I have read this in other discussions and on the Apple page). The problem is that my battery is no longer a 100% of its capacity according to Cococnut Battery. It started with 99%, then back to 100%, then 98, 97... and now it varies from 97 to 98 (right now it says that my computer's current capacity is 6948 mAH). I don't know if this is normal, or if this is caused by the use I used to give to my macbook air at the beginning or by any other thing. I also have 19 loadcycles already. Besides, I have noticed that sometimes it jumps form 100% to 99% of battery pretty fast when I don't have it plugged, and I'm not sure if that happened before.
This is my first time dealing with a macbook and I don't know how these things are supposed to work, and I'm worried my battery might have any kind of problem and that's why itdoesn't have full capacity anymore, since I've been using it for only a month.
Also, sometimes it takes a little while to shut down. It usually takes 2 seconds, but sometimes it takes longer, maybe 20 seconds (first the screen turn white, then the loading icon appears and then it finally shuts down). Is this normal too for macbook airs?
Thanks for the help!

Those are only averages, for purposes of the battery 97 98 99 and 100 are the 'same thing'........theyre all estimates.
Normal on shut down, sometimes you can see a few seconds, sometimes 10, 15 seconds shut down.....depends on what and HOW much its shutting down before poweroff.   Normal.
ON BATTERY USE:
Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                          (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
*However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
From Apple on batteries:
http://support.apple.com/kb/HT1446
http://www.apple.com/batteries/
Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace

What is the battery life span of ipad2? How do you know when it is dying?

I have only a PC and afraid to loose what I have on my iPad if the battery goes dead. This happened to me on iPod when I lost every thing after 5 years of using it.

Battery will last about 2 to 3 years.
Sign of failure:
1. Very hot when charging
2. Not holding charge; discharge very quickly
3. Takes a long time to charge

T500 users, what's your battery life?

Here's my specs:
T500 2.4ghz w/ 4gb ram, purchased october 09
Battery: 9-cell
Graphics: "energy saving" mode
Life: only 2.5 hours battery life, three if I'm lucky.
Usage: just have about 10 tabs open on chrome, no flash or anything
What are you guys getting? Other reviews claimed people getting about six hours. I did the battery gauge reset earlier today, it calculated a max of a little less than three hours as well.
My friend's t400 2.2ghz (with 9-cell) seemed to last for six hours easily, possibly more than that.

I ended up stumbling upon this thread ( http://forums.lenovo.com/t5/Windows-7-Discussion/Battery-Life-Decrease-In-Windows-7/td-p/168772/page... )and have the same symptoms of the fan constantly running among other things.
I'm updating power manager to see if it'll fix things, otherwise I'm getting tempted to cave and buy something else.

Once the user has entered the URL they want to add to the form. You can use the loadXML function to implement some special text in a label...
var linkValue = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><exData contentType=\"text/html\" xmlns=\"http://www.xfa.org/schema/xfa-template/2.8/\"><body xmlns=\"http://www.w3.org/1999/xhtml\" xmlns:xfa=\"http://www.xfa.org/schema/xfa-data/1.0/\" xfa:APIVersion=\"Acroform:2.7.0.0\" xfa:spec=\"2.1\"><p style=\"font-weight:bold;text-decoration:none;letter-spacing:0in\">The new link the user have entered is:<a href=\"" + textfield.rawValue + "\">textfield.rawValue</a></p></body></exData>";

What is average battery life everyone is getting for the Zen Mic

I just got my Zen Micro last Thursday. I'm concern about the battery life. I haven't fully tested the battery yet, but I'm estimating that I will only get about 6-7 hours for it. The advertised time was suppose to be as much as 2 hours. Now I know that depends on your usage (e.g. volume, bitrate of the file, play mode, etc.). What are other people getting? Thanks.

My last test, I tried to be as natural as possible. That is: back light is on; shuffle mode is on; eq is on; volume is normal (at 4 to 6); I skip or go back to tracks; I fast foward; the contrast is at 50 percent; average bitrate (from 28 to 360); smart sound off; and other minor things that I can't remember. That test gave me only 7.5 hours.
I think that is pretty modest usage. Any average mp3 user would do the same thing. Yet, I only got 7.5 out of the possible 2. I don't like the sounds of that.
I'm running another test right now with the same conditions above, and I'll let you guys know what I get.

Yes, I think most of us do understand what open source software is. It sounds as if you don't. Here's some information:
Open-source software (OSS) is computer software that is available in source code form: the source code and certain other rights normally reserved forcopyright holders are provided under an open-source license that permits users to study, change, improve and at times also to distribute the software.

What does it mean when there's a picture of a lock with an arrow going around it? (it's showing up next to the battery life %)

this pic of a lock with an arrow going around it popped up today. what does it mean???? It is located on the top of my iphone next to the battery life percentage. Help??!

This is covered in the manual. it explains all the icons.

Installation of the new OSX is very heavy hdd load, in addition spotlight reindexes all the files on your computer - it may be a few hours. If in the future will be the same macbook hot, you should contact your nearest Apple Authorized Service Provider.
May be required to clean notebook cooling system.
You can also install any monitoring utility sensors to your mac such as Hardware Monitor and look at the value of the temperature sensors.

What is wrong with my phone if the battery life is draining while the phone is in the lock position?

Last night my phone just started getting extremely dim and I had it on the brightest setting. It was so dim you had to look at it under a light just to see what was on the screen. It then proceeded to lock down. I plugged it in but it would not charge. Finally, after almost an hour of being plugged in it finally started charging. It is acting completely normal except that it is constantly warm and the battery life keeps draining even when it is not in use. Does anyone know what is wrong with it? Can it be fixed? Normally, how much would this cost me? Your help would be greatly appreciated!!

Your phone is probably broken.

Nexus was turned off, then froze... what drained the battery?

I have a 3 month old Nexus running the latest Android OS. I don't have many apps or widgets, and the ones I do have, I have set for manual updating, so I can see what is going on. Periodically, I turn my phone off, like at night when I don't want to hear from anybody. I did it early this morning, but could not get the phone to turn back on - the power button wasn't functional.
I should have done it from the start, but upon taking the phone to a VZW store (which turned out to be just a 'premium retailer' - no repair or service offered), we popped the battery, and the phone came back on after pressing the power button. The salesman tried checking some settings (actually, only the 'sleep' setting, changing it from 5 to 1 minute. I noticed that the battery level was showing the need for a charging, and I know the phone was at around 75% when I turned it off. The reason I didn't pop the battery originally was that I was having some trouble with the power button not always working when it should (there have been a few times where I could only turn the phone back on by pressing the bottom half of the power button).
The phone was off for about 4 hours. When I got back home an got it plugged into the charged, I took a look at the battery usage, and the attached is what I found. A basically straight-line drop in battery power, I am guessing from the time I turned the phone off until after I got it back on charge.
So I'm wondering... what caused the power drop? If the phone was off, the power shouldn't drain like that, if at all. Even running all my apps and widgets, the phone shouldn't get so low so fast. And nothing has been updated in at least a few days, and I have turned the phone on and off since the last thing was updated.
Has anyone seen power activity and phone activity like this before?
Thanks!
Frank

Haven't seen that but last night I had something similar occur.
Last night I powered my phone down, while fully charged, before I went to bed and when I woke up this morning it would not turn on so I plugged it into the charger and it showed the battery at 0%.
Then just a short while ago I left work and ran to the store. My phone was fully charged when I left and I was only gone 30 minutes. The wifi was off and during that time I recieved one text which I read and then turned off the screen but in those 30 minutes my charge dropped from 100% to 80%.
Now my phone, and the battery is a year old (called the local Verizon store where I got it and believe it or not I'm 1 week out of warranty. lol!) and while the battery life has always sucked, and I might expect some reduction in it's charge capacity but such an aburpt reduction has me wondering what's going on.

What do i do if the battery life isn't what it should be?

I got my Ipod in late January or early February as a late xmas present, and since then it's become the closest thing to crack I can think of. However, I never really listen to it for more than say a 1/2 hr in the am another 1/2 hr in the pm. Maybe 2-3 days during the week I'll plug it into my computer at work and almost never watch video on it. I've run the battery test w/almost default settings, but the battery life seems to be around 6 hrs. Why is that? and what should or can i do about it?

Make sure to run the most current updater on it and then re-test it.
