OS should allow choice between "deep" and "light" sleep (battery life)
It's clear that Apple needs to fix the OS for the ipod touch so that the user can choose between one of two sleep modes. A "deep" sleep mode would be similar to sleep in pre- OS 4.1: WIFI would be automatically turned off to preserve battery. A "light" sleep mode would be similar to the sleep mode in the current OS 4.1 and would not shut WIFI off (but thereby quickly draining the battery).
you might want to let Apple know via _*iPod Touch Feedback*_.

Please advise me as to any method to restore a 1 year old 4S, keep apps from crashing or disappearing. and to reserve battery life? Information on WiFi malfunction would also be greatly appreciated. Sprint is unfortunately my carrier and I suspect a lot of resources are overtaxed to maintain connection. Any advice for this phone, or do I just need to upgrade to a model with new reception technology? Thank you.
Thank you, Chris, for the optimistic reply! In terms of self-resolve I have done everything, including restore to original- to accomplish this I had to re- install Win 7 on a low use machine, as it could not be done with 8.1 Pro- attempt made with Apple advanced tech who also was unsuccessful at even getting the phone to restore with 8.1. I was going, with lots of time and assistance from the tech, to send in for a replacement, until I made one last try with older workstation and without using backup- didn't want to inherit old problems. The phone worked fine for a month or so and then reverted to the problems above. Wi-Fi is not greed out, but won't connect to some sites and 3G is usually faster and more reliable - on the phone, not computers. My data measured usage of data has spiked, I guess that is related to struggling for a Sprint connection. Battery life is rapidly degrading, was okay after restore.
Upgrade thinking was to improve antenna technology. I have owned, personally and as a company, over 50 iPhones. I have loved them, but can't seem to get a straight answer from Apple on this one; which makes me consider options. Has anyone resolved similar problems with the 4G? Fix, wait for 6, switch carriers or switch manufacturers? Is Apple switching it's focus to mass market, cheaper and less expensive? -
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 have owned an iPod touch for about a month now and I having some problems with it. On occasion, my iPod is running very slowly, even when I keep my multitasking bar empty, the native apps such as the App Store, Music, Videos, etc. lag a lot whenever i try to access content. This was not the case for me when I was running iOS 4, in which my iPod ran extremely fast and had great battery life. I most of the time keep my wireless turned off (to be specific, i turn on airplane mode approx 3/4 of the time) along with my brightness turned all the way down. Any suggestions?
I also have another concern with my storage space. I have an 8GB 4th Generation, and whenever I plug it into iTunes, I notice nearly 700MB of space that I am not using on my iPod, I have gone through all of the data and calculated that the 700MB of space that iTunes classifies as "other", i am not using this storage space. Is there anything that I can do about this or do I have to erase everything and restore to get rid of this?
Thank you for taking the time to read my question, and if you can, please answer.
Thanks.- iOS 5 does slow the iPOd. Periodically powering off and then back on helps since it free up memory that apps do ot release. The iPod only has 256 MB of memeor and low memory slows the iPod.
- iOS 5 also increases battery drain. I leave mine in airplane mode when not using wifi or BT. Also see:
iPod: How to extend battery life
- An other of about 1/2 GB is normal and expected. to get it down you need to restore your iPod. Sometimes restoring from backup works but sometimes a restore to factory defaults/new iPod is required. -
My iPad 2 is only 7 months old and is draining battery life quickly some days and others shutting off at 40% - 50% and when I turn the iPad back on it keeps turning it self off continuously. I have a feeling the battery could be faulty, what do I do?
The Basic Troubleshooting Steps are:
Restart... Reset... Restore from Backup... Restore as New...

I upgraded to iOS 5.0.1 yesterday, and now my battery life has really deteriorated since.I was making it thru the day with about 70% battery life left. It is now 3:30 and I'm already down to 50%. The upgrade worsened my situation. Any help out there?
I had the battery problem. I upgraded the to iOS 5.0.1 last night and at least that problem seems to have been fixed. However, the problem with no audio on phone calls remains. Have not tried swapping the SIM card yet. The ATT guy says that they have resolved 90% of the no audio issues with a new SIM card. Not sure athat what has to do with anything but will try that first before requesting a replacement phone.

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

Just got my iPad 2 three days ago and noticed the battery life drops faster than I expected at least compared to the others ones around, please I need to know the cause and how to effect necessary changes that will prolong the battery life as I have gone through the settings which includes turning off the push notifications, reduce brightness and so on but that doesn't seem to help much.
FYI
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.

What should I use between JSE and JEE?
Is it true that JSE can do only certain level, but JEE can do the same with JSE and specially beyound of JSE.? If i want to develop a web application, what should i install to my computer between JSE and JEE or i have to install its both?
hi
you dont get all the features of j2se when you have j2ee with you. they are 2 different things.
j2ee mostly deals with things which are required for a enterprise application building which include EJBs, Servlets, JSPs etc. while the J2SE is more useful for application developement (using Swing e.g). this is only a crude differentiation.
the choice betweeen the two depends on your requirement. e.g. if you are developing a web application, you will go for J2EE and proceed using the components available there.
if you specify your requirements, then we can discuss the details may be.

Making choice between socket and RMI
I never use RMI, but i am familiar to socket programming. i want to write an online game, I know that use RMI will easy than use socket, could anyone tell me what factors will affect the choice between using socket and RMI if don't consider which one i am familiar ?
thanks
jackyI would consider the amount of traffic your online game is going to be generating. Obviously, if the traffic is the bottleneck, you will want to optimize it as much as possible.
I can see that if you are familiar with sockets and socket programming, where this is very appealing because after all, you can't get much faster than raw sockets. Also, the Java APIs around sockets are much easier than the equivalent BSD Socket C/C++ libraries.
Still, RMI has much more to offer.
o It is relatively easy to set up a connection
o exceptions will be thrown when problems occur
o serializing classes is so easy it's laughable
o If performance becomes an issue, you can (as the previous poster suggests) create your own custom socket factory which optimizes the used bandwidth. Options here include compression if you have the CPU cycles to spare.
o There are mechanisms in place for working RMI over firewalls
Many of the things that RMI offers, you might find yourself re-writing in your own socket-based API. Personally, I would choose RMI. -
Hi, I'm in a bit of a dilemma, I would like to buy a BB but dont know which model to take, either the 9300 or the 8520. I have read through the differences between the 2 handsets and more or less the 9300 is better on paper.
The provider is offering me the BB 9300 for 190 pounds (I'm just converting this into pounds) MORE than the 8520.
My question is that, is the 9300 a 190 pounds more better than the 8520?
Thank youHi and welcome
Good thinking to check first. Thanks for converting into £ but this is multi-national so no need. Now as you have done I will explain about here in the UK.
I'm guessing you are in the US and it seems to me you guys pay a fortune for devices and still have to buy carrier time.
In the UK, at present, if you sign up for an 18 month carrier contract which will cost around £10 per month inc 500Mb data you get the 8520 FREE, nada, zip. And you get 12 months carrier warranty on the device as well. Maybe there are similar deals around you?
The 8520 does not have GPS functionality and this makes it cumbersome for applications that rely on location settings such as FB Places and many others.
The 8520 is unlikely to receive the latest software - OS 6 due to limitations of the memory/processor. OS 6 is available for the 9300 and will probably come pre-loaded. There's nothing wrong with OS 5 but it cannot be upgraded on the 8520.
Whichever you choose, make sure you have a data plan; without data you seriously limit the functionality of any BB and don't worry about extra data costs unless you have no Wi-Fi at home and want to be downloading music/video constantly. Last month, I used 2.6Mb of my 500Mb allowance.
Good luck and hope to see you on here regularly.

I don't know why the battery life has just become so poor. I can listen to 1 song and lose 1/2% battery life. I had all the settings the same as before updating to ISO6 and now it just goes. I did drop it around the same time but I have a stong case so I don't see how this should effect it. If anyone knows how to fix it would be a great help because I used to love iPod but I am very dissapointed.

Save and Protect your iPad Device: How to Save and Prolong the battery life of your new ipad
Please, as you read add more answers to this on how to prolong and save your ipad battery life. Thank you
Saving the battery life of your iPad
1.Keep Your iDevice Out of the Sun
Whatever you do, don’t leave your iPhone or iPod sitting in a hot car—heat kills batteries faster than any other factor, and your device that used to keep a charge for hours will eventually barely hold a charge, and you’ll have to pay Apple to get it replaced. The same thing holds true for any really hot environment: try and store your device in a cool place.
Reduce the Screen Brightness
If you keep the screen at maximum brightness all the time, you’re wasting a lot of battery life—and the screens these days are so bright anyway that you don’t really need to, especially at night. Head into Settings -> Brightness & Wallpaper to adjust the default level of brightness, which you can probably keep as low as 30% most of the time.
2. Make Sure the Screen Locks Quickly
Even if you’ve adjusted the screen brightness, there’s still no substitute for having it turn off quickly when you’re not using it. Head into General -> Auto-Lock to set the screen lock to happen as quickly as your device will let you. This makes a big difference if you are always picking up your phone and putting it back into your pocket without turning the display off.
3. Use Airplane Mode When You Don’t Need Internet (iPad/iPhone)
If you’re busy spending the next 8 hours playing Angry Birds, there might not be a good reason to have internet access, so you can consider using Airplane Mode, which turns off both Wi-Fi and the regular wireless radio. Of course, this will prevent phone calls if you’re on an iPhone—but if you’re busy with Angry Birds you probably don’t want the interruption anyway.
4. The more important reason to use Airplane Mode is when you’re mobile in an area with a really spotty connection—because the iPhone or iPad will try to stay connected at all times, it’s going to be constantly searching for a connection, which can drain your battery. Head into Settings and flip the Airplane Mode switch right up at the top of the screen.
Use Wi-Fi Instead of 3G if Possible
According to Apple, the iPad will get 10 hours of battery life under regular use with Wi-Fi enabled, but will only get 9 hours using 3G—the iPhone gets 6 for 3G and 10 for Wi-Fi. Of course, if you’re heavily using the Wi-Fi, you’ll still be draining the battery—the point is under similar workloads, Wi-Fi is better than 3G for battery life.
You can enable Wi-Fi under Settings -> Wi-Fi, and then pick the network you’d like to connect to.
5. Reduce or Eliminate Mail & Calendar Checking
If you’ve got a bunch of email, calendar, or contact accounts configured, and they are all being checked and downloading email on a regular basis, you’ll be draining the battery an awful lot faster than you need to.
Head into Settings -> Mail, Contacts, Calendars -> Fetch New Data and change the setting to the least frequent check possible. If you don’t use it often, you can just turn Push off entirely and then manually check when you need to.
6. Reduce or Eliminate Push Notifications
Do you really need notifications from Twitter or whatever other apps you’re running? You can turn these off one-by-one, or turn off Push entirely by heading into Settings -> Notifications, and save a bit of extra battery life since your device won’t be pulling in data for those applications anymore.
7. Reduce or Eliminate System Sounds
This one is probably a little silly, but if you really don’t care for the system sounds you can save a small amount of battery life by removing the sounds. A very, very small amount, most likely. Head into Settings -> General -> Sounds to change them.
8. Disable Location Services
If you don’t really need the location services, you can disable them to save some battery life. Head into Settings -> General and flip the Location Services setting to off.
9. Disable Bluetooth If You Don’t Need It
If you don’t use a Bluetooth headset or keyboard, you should keep the Bluetooth radio disabled to save some extra battery life. Head into Settings -> General -> Bluetooth to flip it on or off.
10. Disable Vibrate Feature in Games
If you’ve got a game that uses the vibrate feature, you can turn that off to save some battery life. This mostly matters if the game heavily uses it, and you’ll need to change the setting for the game. As a side note, and it should go without saying, if you’re running really intensive video games, they will kill your battery very quickly.
11. Charge and Discharge Your Battery Regularly
Your iDevice needs to be fully discharged and recharged at least once a month to operate at maximum efficiency and keep the battery from dying. You’ll also want to make sure that you don’t store the device with a dead battery, as that can also cause the battery to lose charge capability—when your battery dies, make sure to recharge it quickly.

Irem Bright writes and would love your own addition if you got other helpful tips.
Thank you all.11. Charge and Discharge Your Battery Regularly

The reason that Apple suggests you drain and recharge your battery once a month is not because it affects the life ofthe battery. What it actually does is calibrate the battery sensor, giving you a more accurate reading.
Other than that, you done an admirable job of summarizing the Knowledge Base article:
