    Turn down brightness... about 40% works for me.  Turn off Push email.

    Make sure it's fully 100% charged (see link below).


    The quickest way (and really the only way) to charge your iPad is with the included 10W 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 (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



    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.

    The other day I had a chance to try and trouble shoot a friends pad with battery woes.  It was worth the time. 

    I fired up the app System staus and turned everything of, then started putting it back on, one at a time. 


    Screen brightness and radio use do make a difference, but not much in idle state.  And even the 4 g, if you are not doing much, made very little difference.


    What did make a huge difference, at least in this case, was a subscription app to a newspaper, set for auto update.


    Took me a while to chase it down, but the thing was trying to update itself on almost constant basis.   Even while sleeping.  The person was losing  almost 10 pct per hour while sleeping, and at least that much while awake.  Killing off that single app brought idle usage down to near zero, where it belongs.


    So after you have done all the stuff recommended above, which are all spot on, start looking at apps, and find the one that has a constant need to communicate with the mother ship.

    Thanks, pjl.  My new iPad was draining after just five or six days in standby.  I had a trial period for a few newspapers that ran out weeks ago but I still had them in news stand, so they were updating unbeknownst to me.  I went into settings>store and turned off the switch that allows them to download new content.  Hopefully that will fix my problem.  The iPad is supposed to last 30 days in standby.  I would be happy with 15, but five is unacceptable.

    A very helpful post, thank you.

    BTW, it turns out that my short battery life was caused by drain from the cellular radio.  I didn't realize that I had the cellular access turned on in the settings even though I hadn't activated a cellular data plan with any carrier.  I guess the cellular radio is turned on by default on all iPads that have the hardware for it.  I turned off the radio and now the battery level never goes low.

    Well, my ipad mini(wifi) would often get up to full 8 hiurs battery with contionuos use, so... I would't worry much about it... Oh, friendly tip, turn off your cellular, location, and lower down your brightness to really boost your battery. It works for me! :)

  • Neil2 Level 1 (0 points)

    I think the iPad mini uses the newer LTE chip that is more power efficient.  Turning it off in my iPad 3 made a huge difference.

    Optimise Your Settings

    There are a number of iPad settings you can adjust to minimise power consumption and extend battery life, including screen brightness. These tips may help extend your battery life.


    Adjust brightness: Managing the screen brightness is the best way to extend iPad battery life. By default, your iPad has Auto-Brightness turned on.  Auto-Brightness adjusts iPad screen brightness based on ambient lighting conditions; lowering brightness in low light conditions helps to extend battery life. You can adjust brightness yourself: go to Settings > Brightness & Wallpaper and drag the slider to the left to lower the default screen brightness.


    Lock your iPad: It may seem obvious, but you should lock your iPad when you aren’t using it. To lock iPad, press the Sleep/Wake button. You can also set the Auto-Lock interval so your iPad will turn off more quickly after a period of inactivity. To set Auto-Lock, go to Settings > General > Auto-Lock and set the interval to a short time, such as one minute.


    Turn off Wi-Fi: If you know you’re not going to be using Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to off. Note that if you have an iPad with cellular capability and use it to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.


    Turn off cellular data: Using cellular networks when you’re out of range of Wi-Fi connectivity allows you to stay in touch but may also decrease battery life, especially in areas with limited coverage. To disable cellular data networks, from the Home screen choose Settings > Cellular, and set Cellular Data to off. Note: You will no longer be able to send or receive data via a cellular data network.


    Use Airplane Mode (Cellular models) in low- or no-coverage areas: Because your iPad always tries to maintain a connection with a Wi-Fi network or cellular data network (Cellular models), it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.


    Minimize use of location services: Applications that actively use location services, such as Maps, may reduce battery life. To disable location services, go to Settings > General > Location Services, or use location services only when needed.


    Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you to new data. Applications that rely extensively on push notifications (such as instant messaging applications) may decrease battery life. To disable push notifications, go to Settings > Notifications, and set Notifications to off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.


    Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data, and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.


    Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive. If the global Fetch setting is set to Manually, you will not be able to locate your iPad using the Find My iPad feature.


    Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.


    Manage the use of downloaded applications: Use of certain applications — such as games that prevent the screen from dimming or shutting off, or applications that use location services — can reduce battery life.



    Use Your iPad Regularly

    For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100 per cent and then completely running it down).

    The cellular radio uses energy to look for a signal, even if you haven't activated it.  When the signal is weak, it uses a lot more energy.  In my case, this turned 30 days of standby battery life into 5 days.  It can be even worse.  Coverage isn't too bad here in Miami.  I bet it's worse in many other places, especially the suburbs and exburbs and smaller cities.

    Hi Texas Mac Man,


    Your various links re battery life have helped me access Apple Support, whose best suggestion for my battery draining problems since updating to 9.2.1 on my iPad Air is to do a factory reset. Reluctant to do that. They now know that sudden battery draining is a known issue since this update (as it seems to be after every IOS update) and they are going to email me as soon as they've come up with a fix.


    Anyway, one of your links on a different post  took me to a page that said calibrating the battery might help, and it said to let my iPad completely run down to nothing, so that it switched itself off, then recharge to 100%.  However, one of your links on your post above warns that you should NOT run down to zero % battery power as this might irreparably damage the battery. It says to not let it run down below 5% or you may not be able to start a new recharge cycle.


    Which one, in your opinion, is the right one? I think re-calibrating sounds like a good idea, but don't want to get it wrong by either not going to zero% or by going to zero %.


    My iPad Air battery is draining even while plugged in and charging, and it's only been since the update. My useage hasn't changed at all. I've altered as many settings as I can to extend battery life (location services off, screen brightness down, push email and notifications off, i-cloud key chain off, all those sort of things), and I've done the home screen button and power button reset about 15 times, all to no avail. It's obvious to me that it's a software issue, and either it's really draining the battery much much faster than my previous IOS (8, I think) was, or it's a glitch in the battery % monitor.


    I hope you see this, and can let me know re letting the battery go down to either zero or 5% to calibrate it in the hopes that doing one of them will re-set my battery life.

    The best way to get more battery life

    Is to turn off Apps Refresh

    You will get 2/3 more hours on iphone/ ipad per charge .



  • angel_153 Level 1 (0 points)

    Thanks, Brian, but already done that and more besides. Spent two hours in total on phone with Apple support today, it IS a known software issue, and they'll email me when there's a fix for it.


    Currently calibrating the battery to see if that helps any. Apple assured me that you need to run it to totally zero, leaving it after it's powered down at around 2% is fine, because it needs to go completely to zero. They told me iPad batteries are NOT Lithium Ion batts, they're Lithium Polymer, so they don't suffer the same issues,at zero % that Li-ion ones do.


    Thanks for your suggestion, all advice appreciated even if I have already tried that to no avail whatsoever. It's very obviously a software glitch. And anyway, why should I have to run round making alterations to settings that were absolutely fine in terms of my battery life before the 9.2.1 update? As a short term temporary helper, that's fine (done the turning off motion, location services, app refresh, push email, dimmed the brightness, and a bunch of other stuff) but it needs,Apple to sort out whatever's causing the battery to drain so fast, even when plugged in.


    I also had a problem with email taking up a disproportionate amount of space. Nice Apple nan said it could be Ghost Data, and to delete then re-add my accounts. Did that, on three of them, and he was right. My email now takes up 782MB instead of the 2.2GB it was hogging before. And no, doing that didn't stop the rapid battery drain either.


    Best wishes,
