Should I turn Airplane ON to increase battery life?

I often use Wi-Fi so I wonder if I turn Airplane mode ON all the time, it can save more battery, right? Also I usually turn off my phone at night when I sleep, is it ok?

WRT putting your phone in Airplane mode, it will extend the battery life because it turns off all the parts of the phone that connect to networks. This includes your cellphone. So if you don't receive calls on your phone it will not hurt anything but you won't be able to make or receive calls, use any GPS apps like Maps or store locators, or connect to the internet. You can use the apps on your phone that don't connect to the internet but that is about it.
It's not that simple. Putting your phone into Airplane mode will frequently DECREASE battery life, because there are still apps running on the phone, many of them need access to data, and if they can't get that access they will keep retrying until they can again connect. While you can kill some of the apps that use data if you remember to before putting the phone into Airplane mode, there are some that you can't kill, like email, contacts, calendar, reminders, Notes, Weather, Stocks, Game Center, etc.

How to increase battery life, and how this could be automated by Apple

This is something I submitted to iPhone feedback via their webpage. I thought that some of the suggestions (if you do them manually) would help out with battery life a bit, obviously disabling and enabling services all the time is a pain, but it will for sure help, and if it was automated that would help as well...
There are several settings you could add to the iPhone that would greatly increase battery life for users
1. Have the GPS radio shut off after a period of inactivity from the accelerometer, if the iPhone isn't moving there is no point in wasting battery life keeping the GPS radio on, have it remember the last position before shutting off to help speed up location reporting once the iPhone starts moving again.
2. Have an options screen that allows users access to all the iPhone services that consume battery, this would make it easy to understand what services use battery and will make it easy to disable those that are not currently required, order the list with the highest battery consumer at the top and the lowest at the bottom, this way people will understand that disabling those services at the top of the list will get them higher increases in battery life. Currently to toggle the battery consuming services requires visiting several menu screens, some several layers deep into the settings pages, people don't bother doing this and thus complanin about battery life.
List of services to include on this page at minimum:
Push, wifi, wifi auto ask to join networks, bluetooth, 3G, location services, notifications, ringer/vibrate, screen brightness, time to sleep, airplane mode
Would also be good to be able to schedule ringer type/volume/vibrate, a lot like profiles on the blackberry.
3. Have the option to schedule times for various battery consuming services to be available. I don't have wifi at work, i would save battery life if wifi was automatically disabled between 9am to 5pm, sure i could do this manually every day i get into work, but most people won't, if they can schedule it then there is no worry that the iPhone will always only be running those services that are required at the time. Of course there needs to be a manaual override in case something changes, like lets say i don't go to work on wednesday i would want wifi on for that day. Would be best to have these programable services on a 7 day schedule, or at least 5 weekdays and 2 weekend days, but the ideal is obviously that each day can be set seperately and accomodate all sorts of life schedules, just like a 7 day programable thermostat.
Currently a lot of people are complaning about battery life, mostly it is because they don't know what to do to conserve it, or they are too lazy to change settings all the time based on current usage and service requirements. Adding these functions would give people the ability to bettery manage the battery life on their iphones and would help to reduce the amount of complaints.
Thanks very much!

Actually it is already that way. GPS radio is usually off, unless needed by applications. The problem is that many applications need it (including free apps that include geo-location based advertising) and that's when GPS works some extra. There's also another factor in making GPS drain battery: it is not the GPS radio itself, but communicating with apple's Map server while using it even if you're not looking at any maps. The thing is that location services rely on some information that can only be obtained through communicating with a geo-location server. Which is another drain factor.
2. Have an options screen that allows users access to all the iPhone services that consume battery, this would make it easy to understand what services use battery and will make it easy to disable those that are not currently required, order the list with the highest battery consumer at the top and the lowest at the bottom, this way people will understand that disabling those services at the top of the list will get them higher increases in battery life.

Unfortunately it is not that straightforward at all. It depends too much on the type of network you're using and on many other factors. It is impossible to have a reasonably reliable ranking like the one you're suggesting.
What could be useful is to have a single switch that controls all services that rely on persistent connections (push, application notifications, some other things) but it is not that trivial at all.
3. Have the option to schedule times for various battery consuming services to be available. I don't have wifi at work, i would save battery life if wifi was automatically disabled between 9am to 5pm,
Having WiFi on while having no WiFi coverage consumes, err, well, almost nothing. Especially in standby, when the phone keeps WiFi radios off at any rate. WiFi is the least expensive bi-directional radio and iPhone manages it very well.

A lot of people are complaining (including myself) because *it does not work right*. Not because I can't switch things off when I don't need them.

I have the new iPad. Even with airplane mode on, my battery life is extremely limited. Is there a problem with the battery? I used to have the ipad2 and had no such problem.

What is your brightness setting & how many apps are open?
The quickest way (and really the only way) to charge your iPad is with the included 10W 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 (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.

Limiting processor speed to increase battery life.

Does anyone know of a way to limit the processor speed to increase battery life while on battery? I know of some windows utilities that will allow you to scale back the processor, to say, 1 ghz or so, so as to get better battery life. Is there any way to do this with a macbook?
Thanks,
Zach

Try CoolBook Controller out. It should do what you want.

My iphone wil not turn on, it has some battery life but will not charge or conect to itunes?

Your battery has reached the end of its life. If you have a MacBook with the removable battery you can get a new third party battery fairly cheap on eBay.

i am getting a flashing ad on my scrabble app offering an upgrade to increase battery life. Is that from Apple and is it safe to download and will it truly increase the battery life. I play scrabble and words with friends, i do not watch videos or anything and the battery life *****

The iPhone 3G can not be updated anymore so don't click ads like the they don't work. Also the iPhone 3G is old enough that it needs a battery change. You can go to apple or an authorized service provider.

Satellite U405 - What is the best way to increases battery life

Hi everyone!
I've been looking for this quite a bit and all I could find are conflicting answers and some confusing instructions... :)
Even the PDF file for my U405 has some conflicting tips (is it recommended to fully discharge it or not?)
Let's say that I don't want to remove it and store it with a 40% charge in a low temperature location (?) because I also want to trust it as a UPS (power failures are common where I stay).
So, in short, what is the best way to prolong my battery life to its maximum? Should I fully discharge it once a month or only half way through? Should it never be fully charged or that's actually a good thing?
Thanks in advance for any wisdom anyone can offer on this!
David

The best way would be indeed to put it out of the notebook, but you already said, you won't do this.
So, I would say to fully unload the battery once in a while and load it to a maximum.
This is all I can tell you right now, but don't know how much this will increase the battery's life.

Increase battery life with iOS4

Besides for turning off Wifi or push notifications, or shutting down, is there anyway to make the battery life last longer than it does with iOS4?

The answer, I regret to say, can be found in [this thread|http://discussions.apple.com/message.jspa?messageID=11980463#11980463|Th e sad truth about iPod/iPhone battery life].
In order to upgrade this solution from a suggestion by someone who isn't suffering the issue to an account of firsthand experience, I'll tell you that in a household with 2 iPod Touch devices that were both decimated by the upgrade to iOS4, this method cured the battery life of both units and will probably work for you.
+The solution boils down to the following:+
Using iTunes, run the "Restore" to factory settings.
I performed this technological equivalent of ritual sacrifice with full knowledge of the devastation it would wreck on the volumes of settings/passwords/usernames/servernames and countless other bits personal information manually entered over 2 years. I did it partially because I only half-believed it would work and was wantonly hoping for an even greater excuse to complain. 3 days later, I'm still finding information I have to look up and reenter.
+For my own part, I would have greatly preferred the ability to restore my iPod to a state just prior to installation of iOS4.+
Perform this restore at your own risk.
On the 4th page of the thread linked above, +Lawrence Finch+ describes a few less drastic steps you can attempt first if you are equally reticent to give your iPod a lobotomy. I tried them all. A series of acts which served only to prolong the inevitable and increase the amount of time wasted as well as to further inflame my ire.

Does increasing the RAM reduce or increase battery life?

Recently I upgraded my Macbook Pro i5 13" Early 2011 from 4gigs of RAM to 8gigs. The RAM I used are PNY - 4GB PC3-10666 1.3GHz DDR3 SoDIMM Laptop Memory. I bought them at bestbuy and the "tech guy" said they were fine to use on a mac (and they were.) So I go home and install them. I love the speed boost it gave but the down side is it that it cut my Macbook's battery life down from maybe 7 hours down 5 (That's doing the exact same thing before I upgraded.) I searched online forums and they both have conflicting answers. Some say that adding RAM should improve battery life because the HD get accessed less. (http://forums.macrumors.com/showthread.php?t=1090350) Others say that adding RAM is reduce battery life because it refreshes all the time. I know cheap RAM like these do not come without strings attached, but is it possible that I may have gotten faulty RAM? If so, can you guys recommend the correct kind I should be using? I still have 3 weeks to return them.
Oh on a side note, I was thinking of upgrading to an SSD. Does that also reduce battery life? Here's what I had in mind, http://www.amazon.com/gp/product/B005T3GPXE/ref=gno_cart_title_3
Anyways, that's all.

How can i increase battery life in my iphone 5 after ios7 upgrade

will apple fix this huge problem of half of battery life in my verizon iphone 5 after ios7 upgrade? or should i just go back to ios6?

all I can say is APPLE has no official way to go back to a previous version of OS X. Perhaps there are hacks, but I cant speak of them here. Also, that link was only given to you an hour ago, so give it more time to see if it helps with battery life until a more stable version of iOS 7 is released. Im not happy about the battery life either.

My iPhone 4 is turning itself off after 40% battery life is surpassed.

Although I still have about 40% charge on the battery, the iPhone just turns itself off, like it has no battery life at all but when i plug it into the charger, it starts up again automatically and shows that I still have about 40-45% battery life available. What is going on? How do I try to recalibrate it if I can never get it to 0% battery life? Please help.

Same case here, but mine is Iphone 3GS having 40-50% battery then a little moment boom, it shut itself off. How to fix this someone help.

Increasing battery life on my iphone 5 (6.0.2)?

erg.
i just bought a new iphone 5 and was really hoping to get better battery life than my iphone 5.
first couple of days i was really psyched because i would put it on a full charge over night and then i would have a full 100% at the end of the day. pretty much it would last until right through the next day.
Today i put it on a full charge, didn't use it a lick and i have 21%. If i use the phone i run out of charge around 5 or 6.
Can anyone help me figure out A if i can get better life out of this thing and B if i should expect this to get worse and C whether some of these phones are better at holding a charge than others?
it is going to be a real drag to have to carry around an additional battery pack just to get through the day when i am not even using it.
i have Fetch New Data off.
THANKS

HT4275 how to increase battery life

My battery life suddenly decreased substantially. Just in the last couple of days

I've seen the same phenomenon as well. The trackpad batteries sometimes last a month or more and then suddenly they only last 3 days. I haven't pinned down what's causing the devices not to go into low power mode yet, but certainly a software bug. Until then I use rechargeables and always have some ready.
