Here's my usage for today. Unplugged at 6:50am. Used practically all day on LTE. Not bad at all. Defiantly what's promised at least.
Usage:5 hours 58 minutes
Standby: 11 hours, 24 minutes.

iPad Air 32GB Wi-Fi

I got 18 hours 3 minutes battery over 5 days 2 hours,
when used only for web browsing at 35% brightness.

I got 15 hours 22 minutes battery over 3 data 11 hours,
when used for mostly web browsing at 35% brightness,
some 80% brightness video/photo/camera use,
and some displayless podcast playback.

I could probably get a little more battery life if I had made a few control settings changes, like turning off location services and push notifications.

This iPad Air is mostly excellent, BUT there is a problem with green display overcast, so I may be returning it.

I also have an iPad 2 16GB Wi-Fi over 2.5 years old (bought first day available) that recently got over 12 hours battery when used mostly for web browsing at 35% brightness. Considering that this one has been heavily used it is surprising the battery is still so good.

This is my first iPad but all I can say is WOW this thing blows every other gadget I own away in terms of battery life. I have 10% battery remaining and had 19 hrs 22 min usage and 5 days 9 hr standby. Only if they'd fix the crashing… (I hear 7.1 fixes these issues).

Mine is non LTE and through normal usage I get to about 50% after about 3 days. If I use it more heavily maybe 50% after 2 days. I usually plug it in if I get below 50%. With the crazy Buffalo weather, I like to have as much charge as possible for entertainment in a power outage lol.

i just plugged in to charge, so its added the "battery has been plugged in since last full charge" message, but prior to just now, my year and a half old iPad 3 wifi was at

usage: 1 day 2 hours, standby: 6 days, 20 hours, remaining: 20%

i literally haven't plugged it in all week, and generally use it a little each evening for video and internet. so maybe it was misreporting, but it "seems" right, and if so, that seems pretty freaking unbelievable.

the best guess i can make is that since it does all those background app refresh things in ios7, perhaps they have pushed up my usage with minimal power draw.

Either I have a super iPad or my usage is way below the average user. I constantly get 20 hours of usage with my iPad Air. I see so many people blown away with their 13 to 14 hours of usage and I'm just sitting here like: :confused:

I don't think that's it. I have background app refresh turned off and I still get 20+ hours.

I really didn't know what to expect with my brand new Air. But I am amazed at the battery life--I bought my Air on Monday and charged it that night--and charged it again last night when it was down to 32 percent. Awesome as far as I'm concerned. :)

well my last one certainly wasn't a fluke. a week between charges and reporting an insane 27 hrs of usage! typical activities are browsing the web and streaming video. mostly used at night so maybe its the lower brightness that's helping get these times.

Since updating to 7.1 it appears my iPad Air will get closer to the advertised 10 hours (maybe 12 to 14) I'm going to assume every usage stat before 7.1 was wrong due to a glitch in the system. Those getting more than, say, 12 to 15 hours are experiencing a bug.

A few battery tips garnered from many places. First check out battery university to better understand Li batteries. Also since most of us upgrade to new devices after two to three years or sooner, most any way you decide to charge and use your device will give you a usable lifespan. So no need to get OCD over your battery.

The batteries are rated for about 500 100% discharges and still have 70-80% of full capacity. Note that five 20% discharges equal one 100%. Also, as with all manufactured items, a certain percentage will get a bad battery and or device. No manufacturing process is 100% perfect all the time. If you get a bad one, go to Apple Store and see what they will do for you.

Li battery chemistry hates heat. So avoid high temperature situations as much as possible. If your device gets hot during charging or intensive processor use, try to allow contact with cooler surfaces to draw away heat when in these situations. Never leave your device in a hot car, even turned off.

Li batteries will fail if overcharged or if allowed to fall below a threshold voltage. Use only Apple chargers and cords as the device in conjunction with these is designed to prevent over and undercharge conditions. You may be lucky and use third party charger/cords without incident, but you really want to risk hundreds of dollars to save twenty bucks?

If you want to be kind to your battery, consider usually charging when you reach 30% and ending charge at 80%. This is a sweet spot for the chemistry of Li batteries. When it's convenient, and I reach 30-40% I connect the charger for short time, like 30 minutes and take it back into low 80% range. Of course when I know I need it due being on the go, I charge to 100%. I may be deluding myself, but have noticed increase in duration since I got my iPhone and iPad following this protocol. About very six weeks I will drain to 10% and charge to 100% to recalibrate the percent meter. Doesn't do anything for battery, just adjusts the range of the meter to improve accuracy.


I leave you with this to ponder. Toyota in their Prius Hybrid has the Li battery pack cycle between 60% low and 80% high. Since the battery pack is $10,000 and needs to last the life of car, five years plus. They use this conservative charge cycle programmed into the controller to maximize battery longevity.

Enjoy your devices, and don't be too stressed over your battery.
