How to Extend the Battery Life of an iPad
Just as with an iPhone or iPod Touch, the battery life of your iPad will be shorter during heavy use. However, there are some measures you can take to keep your device on and active for hours of enjoyment, and this article explains what you can do to lengthen the battery life
1.Turn off Wi-Fi and cellular data (iPad + 3G) settings. Your iPad drains battery power when searching for and attempting to connect to the nearest Wi-Fi or cellular network tower, so if you're not planning on using Safari or apps that require these features, shut them off.
* Go to "Settings", "WiFi option" or "Cellular", and tap the off switch.
* Go to "Settings". Tap on "Mail, Contacts, Calendars" and go to "Fetch New Data". Tap "Manually".
* Alternately, tap "Hourly" to increase the fetching interval.
3.Turn off Push notifications. The usefulness of this step depends on how many emails or IM+ you usually receive; if you get a lot, this step is probably worth using as this can deplete battery life.
* Go to "Settings", "Mail, Contacts, Calendars" and "Fetch New Data". Turn off Push.
4. Tone down the brightness. It goes without saying that the brighter the screen, the more battery power your iPad consumes. Turn down the brightness to a setting that looks right.
* Go to "Settings", then "Brightness & Wallpaper".
* Select "Auto Brightness", which will allow the iPad to adjust brightness depending on the brightness of your location; or
* Drag the slider to the left to lower the default screen brightness. 25 percent to 30 percent brightness should be sufficient for daytime use, and for most people, should also work for nighttime.
5.Turn off the sound effects. Sounds can cause the battery to deplete quickly if they are frequent and as they are activated by default, they will sound whenever you receive notifications or when pressing buttons for the on-screen keyboard.
* Go to "Settings", "General", and "Sounds". There are five different options on the equalizer to "Increase/Decrease". Or, you can switch to "On/Off" if preferred. Obviously, disabling the lot would decrease the battery usage by sounds.
6.Turn off location services. Active use of maps and other location services will drain battery life. If left on, Maps updates continuously, something that you don't need draining your battery.
7.# Avoid frequent use of 3D or graphic heavy apps. Sure, BrickBreaker HD looks great in high-definition, but playing for long periods of time drains battery life like a hose.
#8Switch on Airplane Mode if you have an iPad + 3G. It blocks all of the iPad's wireless signals and will increase battery life. In areas where 3G is patchy or weak, this could drain the battery even more, so it's a very good idea to turn it off in such a situation.
#9Keep the iPad away from temperature extremes. Extreme high or low temperatures can cause the battery life to decrease. Keep the iPad environment between 32ºF and 95ºF(0ºC and 35ºC).[2]
* Be careful of using an iPad case when charging the battery, as this can prevent adequate ventilation, increasing the temperature of the iPad and potentially damaging the battery (charging releases heat).
#10Keep your software up-to-date at all times. Apple recommends updating regularly because engineers look for new ways to optimize battery performance and when they find any ways, they pass these on via software updates.
#11Switch on the auto-lock feature. This means that your iPad will turn off after a set period of time if left inactive.
* Go to "Settings", "General", and tap on "Auto Lock". Set the interval to a short space of time, such as one minute.
* Contrary to popular belief, shutting off the iPad when not in use and turning it back on when you do will more often then not, especially in short periods of time, waste battery life because of the energy the iPad takes up trying too boot up/shut down.
* Always charge your device before leaving home, especially on long trips. Bring the charger with you if you are going away overnight, or for an extended period of time. While the iPad battery is slated to last up to 10 hours, frequent use will shorten this time dramatically.
* Perform a monthly battery calibration. Drain the battery completely, then charge it 100 percent.
* Charging batteries in a warm environment reduces the amount of charge accepted by the batteries and lowers the voltage that the batteries are charged to. So charge your iPad in a cool place to get the maximum charge to begin with.
* Understand the difference between battery life and battery lifespan. Battery life refers to the time before a battery requires recharging; battery lifespan refers to the time a battery lasts before it needs to be replaced.
* Apple states that normal battery life for surfing the internet using WiFi, playing music or watching videos is up to 10 hours, while surfing the internet using a 3G network should be up to about 9 hours.
* Repeatedly draining your battery completely (called a “deep discharge”) can shorten the life span of the battery. So, if you use your iPad until the battery fails, you will get more use of your iPad on this particular charge, but you will reduce the number of times you can recharge your iPad’s battery. (Most lithium batteries can be recharged about 500 times. If you are a heavy iPad user, that could be less than two years.)Source URL: http://gbejadacosta.blogspot.com/2010/12/how-to-extend-battery-life-of-ipad.html
