as many people with iDevices know the battery seems to drag all too quickly in the 3.0 and subsequent updates and certainly have not helped things either there are lots of different ways to improve your battery life such as turning off push notifications disabling extra processes if you were jailbroken among many many others however there's a much simpler way to get more after your battery calibrating let's get this one started to understand why calibrating would work first you need to understand how rechargeable batteries indeed for any advice uses it or chargeable battery not just iPhones and iPods work generally a battery will be made to last a certain number of charges the force starts to lose a considerable amount of storage capacity however the battery's capacity is constantly changing as you use the device so your device might hold a certain amount of charge right now but in three months it could be somewhat higher or lower inside each battery there's a small charge meter that checks the amount of charge and or reports it to the device there's a preset low point where it knows it must shut off and a max charge point where it the battery knows that cannot take any more power however because the overall battery life constantly changes you must reset these preset numbers if you don't then your battery meter will become wildly inaccurate within just a few months it makes you think the battery is almost dead when in fact you could have perhaps even hours left while it may sound complicated it's actually quite simple all you need to do is burn your battery entirely down until the device shuts off by itself then immediately plug it in and let it fully charged to 100% what this will do is reset the lowest and highest numbers in your battery effectively recalibrating it this isn't a terribly time-consuming process doing it three or four times a year should be fine and more if you think you can to demonstrate how much this can help let me give you some admittedly rough estimations how far off your meter could be I hadn't done this in nearly six months and my battery meter would go up and down all day I usually like to charge it when it's around 15 to 20 percent now I was usually getting down to that after about four hours of use both of them Wi-Fi and playing games when I went to calibrate it the results surprised me the battery didn't quit for more than two hours after getting to 15% the inaccuracy of the meter was easily apparent after going down to 8% he suddenly jumped up to 30% and slowly made its way down until dying a two percent after recalibrating it there was no more random skipping of the battery and it easily lasts well over six hours now so before you go killing off everything in sight and search at that extra hour of battery life you may want to try calibrating the battery
