    How can i extend the battery life of my iphone 4s? when i left 50% it in standby mode when i saw in 5hours it drains to 5% i saw 45%, i thought when i leave the phone the percent is still the same. whant am i goin to do?

    I was not aware of the fact one could use ringtones as alarms, this will suffice! Although I foresee some very awkward times as the sound does not stop once I respond to the reminder (it keeps going for good five - ten seconds after I "stop" the reminder), but it's better than missing it altogether!
    Thank you very much!
    Regarding the Alarmed app, doesn't it have to be running to actually remind you?
    -Modular747: I don't know anyone who actually reads the terms of service agreement, those things are usually up to thirty, small print pages full of legal jargon. Rules, I do read - not the legal documents (also they often contradict the laws in my country, but that's a whole different story).
    I agree with you - the average customer support consultant mostly cares about keeping his job and earning his salary (don't we all?) and thus racking up completted tasks (i.e. getting rid of customers as fast as possible - in a good mood). The "threat" none the less is real, if a cell phone causes me more trouble than it is worth, I will indeed throw it away (I have done so before) - and recommend a different brand to anyone willing to listen.
    Don't get me wrong, I love Apple and I've been faithfully using and recommending their producs for twenty years now, not because of fanboyism, but because they earned it. This calendar issue, however, is like a toaster that doesn't automatically eject the toast at the set time. I see it as a major flaw and after googling around a bit I see that it's been around since at least 2007 (THAT'S SEVEN YEARS!!) so I strongly believe they are aware of this problem by now, but are choosing to ignore it for some mysterious reason and it really ****** me off.
    I will send the feedback but based on my observations I suspect the Send button is merely a cleverly disguised Delete button.

    Take a look at this to make sure your settings are optimized to the best it can be.
    If all else fails, try and restore through iTunes, set up as a new iPhone and manually sync your apps and media back to your iPhone.
    If still persists after this, you might call Applecare and see if they can run a battery diagnogstics..

  • How to increase the battery life of your N series ...

    What I am about to post here is valid for any 3G phone or device regardless of model but it is particularly focused towards the N series devices and their power hogging features.
    Your battery life is dependant on many many things. How often you take calls on the device, the condition of your battery, the features you use on the device and so on and on. Therefore it is impossible to say that by following the information in this post you will get x amount of days battery life, but it will get you more time out of the battery than you otherwise would have got.
    So with that out the way, if your looking to increase your battery life then follow these tips and your battery should start looking a lot healthier.
    First of all lets start with THE big one. The one that is going to save you the most juice. Switching 3G off.
    Yep, you heard me right. Just by switching the 3G capability of your phone off you will add hours and hours to your battery life. How is this so? Allow me to explain...
    Due to the rather poor delivery of 3G in the UK by the network operators, it is rare for any 3G phone to maintain a constant 3G signal. Instead you will find that the phone constantly flips between 3G and GSM mode (Keep an eye on your signal one day). Even those of you on Vodafone who probably have the best 3G network coverage will find this is the case.
    Unfortunately, this constant flipping between the two modes sucks power from the battery like a vampire as it alters its reception state for the different modes and the constant flipping is..well...causing it do this constantly! It can sometimes even make your phone unavailable for calls for very brief periods as it trips from GSM to 3G and vice versa.
    If you need to use 3G for video calls or whatever then I'm afraid your just going to have to live with this but if you don't (And lets face it few of us do) then you can switch 3G off and increase your battery life considerably.
    To do this, go into the "Settings" application (Found in the menu somewhere, by default Nokia normally stick it in "Tools"), and then to the "Phone" tab. In there you will see an option that says "Network mode" and you have a choice of "GSM" or "Dual Mode" (I.e. UMTS and GSM). Set it to GSM and your phone will restart. Once it restarts it will be working in GSM with GPRS speeds only but really for most purposes this is fine.
    You have now just extended your battery capability considerably. You can further extend it by going to the "Connection" tab, going into "Packet data" and changing it to "When needed" so it is not constantly checking for a data connection.
    The second big change you can make is to turn your phones wifi scanning capability off. The last time I looked not all Nokia's phones that have wifi capability can have their wifi cards switched off entirely but if you can, turn it off except for when you need to use it. Wifi is a power hog.
    The next big change you can make is to lower the screen brightness settings on your phone. The less bright your screen is the less power is being used to light it up. Nokia by default leave the screen brightness at something like 50%. Lowering this a bit more will conserve more juice. Before you do this though please consider the fact that lowering the brightness setting will have a big impact on your ability to see the screen clearly in sunny conditions although you will be fine in the dark as you can't lower the brightness that far.
    To lower the brightness, go to the settings tool in your phone and into the display option (Hidden in a subcategory called "Personalisation" on the N95). It won't hurt to set the power saving time out to 1 minute and the backlight time out to 10 seconds while your here (Although these are the Nokia default so they should already be set to this).
    Finally in regards to the screen, although they may look pretty, animated screensavers use more battery power than the standard blank screen with time and date so avoid them if you can.
    It also helps to keep Bluetooth switched off until you need it although the power savings are minimal in comparison to the other changes but every little milliamp counts!
    Using the above methods I generally get about 3 to 4 days with about 3 hours talktime on my N95 without using Bluetooth, GPS or anything like that (I might be able to get more but so far I have not paid attention to the battery state before I put it on charge). If I am on a long train journey I can get about 4 hours worth of full screen video and about 2 hours talktime over the period of about 24 hours before it needs a recharge. As I said at the start of the post your mileage will vary greatly depending on how you use your device.
    Hope this helps.

    no keffa it is a cop out from nokia

    the n95 battery is atrocious
    dont change the post content as the title is 'How to increase the battery life of your N series device'
    your talking about nokia phones specifically
    the networks are not to blame
    they do not make the handsets : Nokia do !!!!!!!!!!
    I'm going to choose my words carefully here...
    I would never deny the battery on the N95 is not really up to the job of powering the N95 with its power hungry features. To put the same battery into a phone that has WiFi, GPS and a large 320x240 screen, the same one that goes into the E65 which has comparatively nothing compared to it is a bit pants.
    However at no point was I criticising them for the band hopping problem. I labelled the post as how to increase the battery life of your N series device because this is a board for the N series devices. It was a simple choice of wording and not intended to be cutting in any way and I did make a remark that the details would be true of any 3G device at the top of the post.
    What I was trying to point out in my second post is that the constant band hopping the phone is being forced to do that is draining its battery so much more quicker than it would if it had a constant signal of one kind or another isn't quite Nokia's fault.
    They build it to conform to a laid out specification for 3G. However if the network operators cannot be bothered to roll out their 3G infrastructure adequately enough that the phone can find and remain locked onto a 3G signal that is usable then what are Nokia to do other than offer you the capability to turn 3G off until you need it (Although note to Nokia: That **bleep** reboot the phone does when you do this is entirely unneeded and you know it).
    Blaming Nokia for this would be like blaming the manufacturer of your radio for failing to pick up radio because the radio station does not have any transmitters within range of your radio's receiver.
    Finally...this band hopping is exhibited by all 3G phones built by Samsung, Nokia, Sony Ericsson, etc, from their most budget 3G model to their priciest piece and is the reason that all phones with 3G capabilities have batteries that do not last for any respectable length of time because these phones are also having to band hop between 3G and GSM.
    Finally the proof is in the pudding. Turn 3G off for a few days. See your battery improve. Then (Although admittedly this will be harder to do...mcuh harder) find an area where you get a fairly decent 3G signal constantly. Again, see your battery improve. Try it with a different 3G phone...different manufacturer even. The same will be true.
    So I stand by my comment, the network operators and their woeful 3G rollout are the villains costing you a fair chunk of your battery and Nokia cannot be expected to mitigate this....but a better battery would be nice all the same...

  • How to improve the battery life after upgrading 3gs to ios5, how to improve the battery life after upgrading 3gs to ios5

    how to improve the batter life 3gs phone on ios5 os

    Also you may want to check a few things if you have location service turned on for Weather app, cuz every time you check your notification center, it will always check your location for the current update on the weather. If you are in the same location the entire time, you really don't need that on. Also while you are on the location service setting, check some of the apps that uses location service and if you don't use it, then turn it off while you are in there. Also maybe turn them all off and then turn on one at a time and find the culprit.
    If it's not your location service, it could be that one your apps is running in the background. Double click home button, this will bring up the recently used tray, hold one of the app for 3 seconds until the - button comes out, then close all the apps. Or just do a hard reset of your iphone by holding the power button and the home button at the same time for 10-15 seconds until the apple logo appears.
    Anything that will require to data connection will use battery. If you have wi-fi at home, then I suggest you keep it on wi-fi because your iphone will last longer if it's on wi-fi then on battery.
    If none of the above suggestion worked, then I suggest you try restoring your phone and set it up as new and see what happens. Just make sure you have a separate back up for your contacts.

  • Why does the Battery life of my iPhone 4 doesn't last as long as it used to before updating my software to iOS 6? Can this problem be fixed?

    Hey there,
    I have upgraded the iOS on my iPhone 4 to the iOS 6 and now my battery life doesn't last as long as it use to. I read something about Safari syncing some currupted bookmarks and whatnot. I basically need to know how could I fix this problem. I know that the iphone needs to have a decent perfomance regarding the battery life, since I've had it for less than 6 months now.
    Any help will be appreciated!

  • 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.

  • Software upgrade iOS 6.1.2 - since upgrading my software the battery life on my iPhone 4 goes down very quickly, will this be fixed with a further upgrade?

    Just signing into this site and posting a question has used 21% of my battery life! Surely that's not right. Is Apple going to issue another upgrade from iOS 6.1.2 to fix this issue?

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.

  • How to decrease the battery consumption on my iphone 2g, 3.1.3

    Hey,
      I recently asked a question that how to get rid of the turning off, of my iphone 2g!
    someone suggested me to INSTALL a application called INSOMNIA, i installed the Insomnia on my iphone 2g, but unfortunately, it drains my battery within hours! I am really tired of this, even if i check my mail service or my messages after one hour! It drains my battery within hours!
    and its really ***** to charge the cell phone every after 4-6 hours, as i am mostly not at home.
    Please i need the best sollution for this problem! thanks in advance.
    Peace

    Then live with the battery drain or troubleshoot the original issue.
    Installing an app to "rectify" an issue instead of looking ofr a real solution is frankly silly.
    Remove the insomnia app and try restoring your device as new to see if that rectifies the shutdown issue.

  • How long is the battery life?

    Just curious

    If you mean a fully charged iPod Classic battery, when new, it is about 40 continuous hours of music or about 6 hours of video.
    However, it has a shelf life of about 400 recharge cycles, which mean if you recharge once a week, it will last about 6-8 years, although it is not linear, as the capacity is reduced over every recharge, and you may have to recharge more than once a week.
    Most iPod after the first year, has about 30 hours of continuous music, and about 4-5 hours of video.
    Have a nice day!

  • Can't figure out how to solve the decimal point bug in this calculator code

    Hi guys, I'm new in flash and is currently learning how to build a simple calculator with multipliers (plus,minus,multiple,divide,decimal point and change sign) but I'm stuck on the decimal point and change sign.
    var multiplier_old:Number = 10;
    var multiplier_new:Number = 1;
    // .: Sets the multipliers so that new input numbers become decimals of a lower unit column
    action_point.addEventListener(MouseEvent.MOUSE_DOWN, function():void {
              multiplier_old = 1;
              multiplier_new = 0.1;
              point = true;
    // Takes intput from the input_ buttons and adds it to the input after applying the multipliers.
    // If `point` is true then the multiplier_new is divided by 10, also as described.
    function inputNumber(n:Number):void {
              input = input * multiplier_old + n * multiplier_new;
                        if (point) {
                                        multiplier_new *= 0.1;
                       trace(multiplier_new);
              output_txt.text = input.toString();
    Decimal point
    The problem is that when I input 2.7 in the calculator, it will display the values in output_txt correctly. But then when I input 2.78, it will display 2.780000000000000000000000002. This will also happen to other numbers if the input is too big.
    What I want is just 2.78. How do I change the codings to make 2.780000000000000000000000002 become 2.78?
    Change sign
    Any tips on how to start on this one?
    Thanks for your time,
    Zainu

    I think you misunderstand what I mean. The weird decimal doesnt comes out after I press the 'equals' sign. It comes out when im just pressing on the caculator number buttons
    First I click the no.2 button and then the decimal point button.
    So the caculation output display will show
    2.
    after that I press the no.7 button
    2.7
    and then no.8 button. It appears like
    2.7800000000000000002
    This is the code I use when the user press the decimal point button.
    // .: Sets the multipliers so that new input numbers become decimals of a lower unit column
    action_point.addEventListener(MouseEvent.MOUSE_DOWN, function():void {
              multiplier_old = 1;
              multiplier_new = 0.1;
              point = true;
    // Takes intput from the input_ buttons and adds it to the input after applying the multipliers in the method described above.
    // If `point` is true then the multiplier_new is divided by 10, also as described.
    function inputNumber(n:Number):void {
              input = input * multiplier_old + n * multiplier_new;
                        if (point) {
                                 trace(multiplier_new.toFixed(3));
                                  multiplier_new *= 0.1;
                                  //trace(multiplier_new);
              output_txt.text = input.toString();
    I think there is some code wrong in this function that makes this weird problem. I tried putting toFixed method but it's still not working.
    Sorry for this long reply but I have to try my bestto explain with my bad english.

  • How long should the battery life live?

    My Itouch keeps dying after only 3 hours!

    It depends on what you use it for.  If I am listening to audiobooks, my iPod touch will go for hours.  If I am using it for email or other internet type stuff it will last a few hours, but I have a few games I play (Boggle for example) which have 3D animations.  I asked your question shortly after getting the game.  It uses a lot of battery power and in an hour or so of a lot of playing it needs recharging.
