Good battery practices?

I got an iphone today....and I love it!!!!!!!!
I turned it on and have used it today and the battery is almost gone....should I wait until the battery is completely drained before I plug it into the wall socket? Also, is it good for the battery and the phone in general to leave it plugged into the wall all night long, like I did with my old cell phone?
What are good battery practices in general for the iphone? I want to be able to use it without it dying out on me everyday, especially when I need to call someone. I don't know how to use it much....are there application or web things that I could turn off while they are not in use in order to conserve battery power? (How do I turn off edge? The E is constantly on the top of the screen...if I could turn it off, wouldn't that conserve power?)
Any other conserving of power practices would be appreciated!
Thank you!!!

Apple put together a great page on the iPhone battery, check out the link below

hope this helps

Good Battery Practice?

I've just recently ordered my MacBook-- and though I haven't received it yet, I am still curious about good battery practice. If anything, I really want mine to last, and typically if asking just anybody off the street you'll get everything from "put your battery in the freezer" to "take out your battery, when not in use".
Any thoughts? Should I charge it fully, then let it run out before I recharge? Should I use the adapter whenever I have the chance, regardless of the battery charge?
I'm also curious whether I have to charge the battery before first use out of the box-- I looked through manual online, and I didn't see anything on that topic.

It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate or for a few minutes to use in another room. You should calibrate every two months or so to keep the battery fully functioning. If you use your MacBook infrequently, it’s best to re-calibrate the battery at least once a month.
It is best not to use your battery unless you need to. Some people have hurt their batteries by charging then discharging every time they use the MacBook. This will age a battery very fast and cause you to buy a battery sooner than you should have too. Don't discharge the battery just because you used it. Li-Ion batteries prefer small charges over big ones. Use it and then plug it in as soon as you can. The only time my Battery is ever fully discharged is when I'm doing a calibration.
The following links have good information about the MacBook and the care of it's battery.

No just plug in your power supply and have fun. It will charge whie your using it. If you follow my other tips you should get long life out of the battery.

Hints and questions on how to do a good battery maintenance

Some minutes ago, my (now) old battery reached the 0%-charge point.
I had bet the MBP could not stay on anymore but instead, surprisingly, it supported the 0-charge "stress point".
I was waiting for it to go to -1% charge but it didn't happen since I installed the new battery, which had arrived minutes before (just in time.. lol).
Now my questions are: how to do a good battery maintenance?
What do you mean with "cycle" ? A discharge-and-recharge cycle?
What do you mean with "calibration" ?
I apologize for my ignorance Oo

The battery gauge is always an estimate. Your battery consists of many cells ganged together. It is hard to get a good read on battery level because discharge is not perfectly linear, and each cell discharges slightly differently. It is easily possible for the gauge to think it's probably at 0 as defined by the power manager (it's really a minimum voltage, not actually zero, that's why it can go "below" zero), yet there is enough variation in the cell array that it hasn't actually hit zero and so it keeps going.
The fact that zero wasn't really zero has probably been recorded by the battery circuitry and the estimate will probably be adjusted next time. Not resulting in a perfect reading next time, just a reading that is slightly more accurate given the difficulty of estimating battery life.

Any usefull examples of good coding practice in large programs

Hi, ive been writing code for about 10 years now. Know a good bit about labview now lmao! But want to get to know good code practices e.g. in creating large programs, code templates, avoiding race conditions, use of multiple loops and to be able to write code for clients as a contractor. Any one help me??

Good programming practices:   creating Iterator objects

Hi,
This is a question about Good programming practices for creating Iterator objects of ArrayList objects. The following line of code works fine in my program (as ridiculous as it may sound):
        Iterator cheesesIterator = cheeses.iterator();but I was wondering whether Java is automatically inserting the <Type> and new code to make:
        Iterator<String> cheesesIterator = new cheeses.iterator();and therefore whether it is good practice to use these everytime? Thank you. ("full" code shown below:)
import java.util.ArrayList;
import java.util.Iterator;
public class DemonstrateIterator
    private ArrayList<String> cheeses;
     * constructor:
    public DemonstrateIterator()
        cheeses = new ArrayList<String>();
        cheeses.add("Emmentaler");
        cheeses.add("Cheddar");
        cheeses.add("Stilton");
        cheeses.add("Brie");
        cheeses.add("Roquefort");
    public void listCheeses()
         //make an iterator object of the ArrayList object
        Iterator cheesesIterator = cheeses.iterator();
        while (cheesesIterator.hasNext()) {
            System.out.println(cheesesIterator.next());
        /** Exploring the toString and Super functions. **/
        System.out.println("\na toString call to Super returns: " +
                                          super.toString() + "\n");
}

iterator() is just a method that returns an iterator. It constructs an instance of a private or nested class that implements iterator, and returns a reference to it.
As for the <T>, when you declare List<String>, that parameterizes that list with type String. The iterator() method returns Iterator<T>. You can look at the source code for yourself. It's in src.zip that came with your JDK download.
Separate from that is your declaration of that variable as type Iterator, rather than Iterator<String>. Regardless of what you declare on the LHS, the iterator() method returns Iterator<T>. Your bare Iterator is essentially Iterator<Object> or Iterator<? extends Object> (not sure which, or what the difference is), which is assignment compatible with Iterator<T>. If you had declared it Iterator<String>, you wouldn't have to cast after calling next().

IPad revers back to a home screen from another page being used, IE Facebook Good battery and wifi signal

iPad revers back to a home screen from another page being used, IE Facebook Good battery and wifi signal. Sometimes several times in a couple of minutes. Could there be an problem with internal hardware

Hi there
My wife and I have been dealing with a very similar issue with our iPhone 5ss, all battery drain issues started after the upgrade to ios 7.03. We have performed numerous restores and have had 3 trips to the Genius Bar. Finally they gave us new iPhones (yesterday). We had hoped this would do the trick but we have the same problem on the new phones.
This morning I restored one and didn't sign into iCloud. Battery drain is now gone. And when I deleted iCloud from my wife's phone it too went back to normal. So I believe the culprit is iCloud and I am now testing various setups with iCloud to determine which app/setting is causing the problem.
Hope this helps with your phones. I will post again if I can narrow it down to something specific.
Good luck!

What to do for getting a good battery backup for E...

I had brought the E6 after a convincing conversation at the Nokia Priority Partner shop and the executive there told me that E6 is a smartphone and also gives a good battery backup. Only on this condition I bought this new phone but to my misfortune this does not have a good battery backup. Everyday morning I need to charge my battery or the phone is dead. This is very much annoying as well as disappointing. I even suffered software issues with my E6. Thrice I needed to get its software reinstalled and even now having issues with the same. The priority centre only tells each time that you get the software reinstalled and your E6 will work fine. But I'm surprised that E6 only borrows my time to get it checked on the go.
No doubt this phone is one of the best which Nokia has ever brought, but, still if it could help me sort this issue then I would rank E6 to be the best in its class.

Which country did you buy your phone in?
There are many posts dealing with this issue and steps to be taken to increase battery life.
Some important ones are:
1. Switch off 3G if you do not need it.
2. Reduce the mail retrieval frequency if you have configured email accounts.
3. Switch off automatic WiFi scanning.
4. Reduce number of homescreens.
5. Close any background application that you do not need.
6. Switch to power saving mode when you do not actively use the phone for longer periods.

T61p - Good battery never charges off AC

I have a T61p that functions wonderfully when plugged in via AC, or on my (powered) docking station. However, the battery never charges (literally NEVER).
1. I have confirmed it is a good battery (have charged said battery on another T61)
2. Laptop will use the battery if there is any charge on it.
3. When I look at the status of my power (icon on tray) while plugged in to the AC power cord OR docking station, I see a status that says 'plugged in, not charging'.
4. No matter how long I leave the laptop plugged in to charge, it never charges.
5. If I look in the Power Manager at the battery details I see:
Status: no activity
Current: 0.00 A
I have sent the laptop in to Lenovo twice now to have this repared, each time stating the above details to the Help person for my ticket. The motherboard has been replaced, they've given me (another) new battery, hardware diagnostics performed, and updated BIOS/embedded controller. And I still see the above issue w/ the battery NOT charging.
One more note - I am running Windows Server 2008.
Anyone have any clue on this? Would be greatly appreciated!

What charging mode did you set in the Thinkvantage Power Manager, when does set your charging to start at? While everything been changed, lenovo never formatted your hdd and reinstall the OS. So this really points to a software problem, if all else fails, you should reinstall the your OS by restoring to the factory condition.

Good programming practice - Abstract class

Hi all,
I have been trying to help another soul in this forum, and came to the conclusion that I don't know good
programming practice when it comes to abstract classes.
Is this correct?
You CAN implement methods in an abstract class, but it's not recommended.
I have NEVER done this...when is there possibly a need to?
Regards.
/ k

Yes, absolutely, you can implement methods in an abstract class. Any method that all subclasses will perform in the same way can be implemented in the abstract base class. If subclasses perform similiar functions depending on their type you declare those as abstract in the base class. Here is a contrived example that I have seen on job interviews.
Suppose your developing an application that draws on a panel. We want to provide some canned shapes such as a circle, a square and a triangle. We want to be able to draw the shape set or get its color and calculate its area.
Let's define an abstract base class Shape
public abstract class Shape{
    private Color myColor;
   // since color has nothing to do with what kind of shape we're working with, create concrete implementation
   public Color getColor(){
        return myColor;
public void setColor(Color newColor){
   myColor = newColor;
// however, drawing the shape and calculation its area are depending on the actual shape.
public abstract void draw();
public abstract double getArea();
// so then Square would be something like
public class Square extends Shape{
   public double get Area()
      return sideLength * sideLength // assumes somehow we know sideLength
public void draw(){
              // concrete implementation
}we can do the same things for Circle class and Triangle class.
And, if you think about it you'll notice that we could have made a Rectangle class and then Square would be a subclass of Rectangle where both dimensions are equal.
I hope that somewhat strained example helps answer your question.

13" white Macbook will not power on with known good battery

Macbook will not attempt to power on with a known good battery that shows full charge. Also, when Magsafe plugged in, there is no indication (no green or amber light) it is connected. This charger does work with another Macbook (same kind).
I have checked the Magsafe/port for any dust & debris, and have followed the tips listed in the FAQ's for a macbook with no power. As I said, the battery & charger both work in another Macbook.
Suggestions please!

Hi Stephanie. It could be a logic board issue or simply the power button at this point (let's hope its the latter). Can you give us more info on how this happened? Did the computer suddenly shut down or was it stored and unused for quite some time?
Without any power, and with you making sure both the battery and and charger is working, then I would suggest bringing it in to the Apple Store.

8320 won't boot up, even with known good battery

Hi Guys, my first post, hope you can help me.
I've got an 8320 which died last night, initially suspected a dead battery so have changed it this morning for one that is known to be good, as its from my other phone where it shows fully charged.
With the known good battery in the suspected faulty phone I get a bettery symbol with a red line through it.
Is it worth trying to reinstall the software or is it a hardware issue ?
If its worth doing the software how do I go about it ?
Thanks in anticipation of your help.

Good Battery Not Charging

Any suggestions on what the following problem could be and how to resolve it?
First here are my battery specs at the moment:
Charge Information:
Charge remaining (mAh): 913
Fully charged: No
Charging: No
Full charge capacity (mAh): 4829
Health Information:
Cycle count: 175
Condition: Good
Battery Installed: Yes
Amperage (mA): 0
Voltage (mV): 11249
The thing is that we have recently had to replace the AC adapter because our son put the magsafe end in his mouth and we think it may have started frying the contacts (it smelled like burning electronics). We went to the apple store and told them our story and sure enough the AC adapter was fried. So we bought a new one and it seemed to be working fine, charged the battery fully, but now it no longer is charging. The AC adapter is working because we plugged it into my newer MacBook pro and it was doing what it was designed to do (power to the computer and charging battery). One thing I noticed was that on the newer computer the LED light on the magsafe turns on (green on the new MBP as it's fully charged) but ont he MBP that we're having the problem with it doesn't turn on (well in fact, it's more like one a blue moon and for no apparent reason the LED light will be green for a short period and then go off, but while it is green it isn't charging).
Tried resetting the SMC, but no luck, still not charging and the LED light isn't on. The LED looks very faint green, could barely make out that it is on, but this very, very faint green seems to always be on.
Anyways, hope this info is enough. We will be taking it tot the apple store, but first wanted to get our experience out there in case anyone is having the same problem.
Cheers

The odyssey continues...
I just noticed that my wife hadn't updated to the latest Mac OSX update (10.5.8) so I did it for her and this is what I found afterwards. The battery is now in Good conditions and the it is charging. The only problem was that the LED light wasn't turning on.
Charge Information:
Charge remaining (mAh): 3721
Fully charged: No
Charging: Yes
Full charge capacity (mAh): 4402
Health Information:
Cycle count: 175
Condition: Good
Battery Installed: Yes
Amperage (mA): 789
Voltage (mV): 12309
While writing ths the unplugged the magsafe and plugged it back in and it appeared initially that the battery wasn't going to charge, but then suddenly the LED lights came on and it turned organge (as it should be when battery still needs recharging) so all seems good....oh wait, just noticed that the LED light turned off again (by off I mean a very dim green....don't know if dim green light means something). I'll continue to keep an eye on it in the meantime so hopefully all this info is jogging someone's mind on a solution.
Cheers!

Do IOS app developers follow any good program practices?

I've had my iPad (original) a little over two years now, and I can say without a doubt, it is the most unstable platform I've used in nearly 30 years of using computers. Most apps crash routinely, usually while at least one other app is running in the background. Unloading the crashed app from memory and reopening uually works, but is a huge nuisance (and reason enough to me why iPads are not business-ready, except for specific task applications requiring mobility). As one trained in both software and systems engineering, with 20 years IT experience mostly in engineering, I have to conclude that IOS app developers use "code and fix" development, with little testing before release. Of course, in theory it could be that IOS itself isn't well designed to handle multitasking and doesn't provide adequate process isolation. Either way, it makes for a frustrating experience as a user.
Has anyone else had similar issues? Thoughts on why?

The original iPad does poorly with multiple apps open, the memory is just too small at 256 MB. The processor is very slow compared to those in the current generation iPads. And then couple that with developers who are for the most part independent of Apple and merely submit there products to Apple and you get a totally unpoliced set of apps. Some are true professionals and follow very good programming practices, one that comes to mind is the GoodReader PDF reader. Very stable and very powerfully built. then you get into the gamers and Is is almost like they never heard of writing effecient, compact code.
The issue I see is a tightly controled operating system, with app developers handed a set of specs under which to code, but no real controls other than does the app run and is it free of malicious code.
Just some thoughts.

We need a good battery monitoring app

We really need an app that monitors battery usage and breaks the usage down by each individual item--cpu, screen, each app, etc.
It's a real pain to figure out what newly installed app may be causing excessive battery drain when you have many apps installed and there is no app that can tell use this information and from what I understand the developers aren't able to find a way to implement it either, thus the issue resides with webOS.
This is a major necessity in my opinion especially because webOS is designed for heavy multitasking.
Post relates to: HP TouchPad (WiFi)

You can send Pages and other iWork documents to DropBox with the WebDav function (sharing via a server) and the sharing options of Pages, Word or PDF are available to you. The good news is this is easily done via a service called DrobDAV. The bad news is there's a fee, but there's a free trial and an educational discount.
This article at Tech Inch explains it. If you rely on DropBox, as I do, and use Pages, etc on your computer, it's really great. Generally, iPad apps that support WebDav can send the doc to DropBox with this add-on.
http://techinch.com/2011/02/02/integrate-dropbox-with-pages-keynote-and-numbers- on-ipad/
There's also a free DropDAV limited service, but files are limited in size 1MB.
And of course Pages, etc can share to iDisk, which is being replaced by iCloud.

Good battery practices?
