Maximize iPad bombardment life – charging, temperature, and storage

Beginner Tips

iPad teardown

The iPad is basically a big screen and a big battery.

One of the virtually under-appreciated features of the iPad is its fantastic bombardment life. Fifty-fifty with a high-resolution screen and a powerful processor, Apple tree'south tablet offers a battery life of 4 to 6 (or more) hours in the air—meliorate than almost every other competing tablet. This is a huge advantage in the cockpit, every bit information technology'll terminal for the duration of all only the longest flights.

But there are a number of things you lot tin can do to better the performance of your iPad bombardment and keep it in top working condition. First, it's important to know what type of battery the iPad (and the iPhone, for that matter) uses, and how it works. Like near consumer electronics, the iPad uses a lithium-ion polymer battery, often called a LiPo battery. These are the standard in portable devices now considering they have a loftier power density but are very lightweight. When you think about it, it'south quite impressive how big a battery Apple tree manages to put into such a slim device. The latest generation iPad Pro 12.9″ for instance, has a 9,720 mAh battery (36.71 watt-hour battery), merely it weights less than i.5 lbs.

Some other major advantage of LiPo batteries is the manner they are charged. In that location is no "memory effect" like older Nickel Cadmium batteries, and so you can accuse your iPad someday yous want and even leave it on a charger overnight. The battery will also charge very rapidly, to almost 80% in a few hours, while the last 20% is more of a trickle accuse and takes longer. The latest models support fast charging, which tin charge an iPad to 50% in just xxx minutes. This charging pattern is very handy for pilots, specially in the cockpit. LiPo batteries also hold their charge for a long time, so a fully charged iPad that is stored for a month will still have nearly of its charge.

And then far nosotros've talked virtually the "bombardment life," pregnant how long the iPad volition run on a single accuse. But Apple also specifies a "battery lifespan," which is the number of times you tin charge and discharge the bombardment earlier information technology starts to lose capacity. The iPad was designed so that, afterward 1000 charge/discharge cycles, it will still have fourscore% of its battery capacity. Annotation that information technology'southward not considered a "charge bike" every fourth dimension you plug in your iPad. If you used xx% of your iPad's bombardment life every day for 5 days, and recharged it each solar day to 100%, that would be ane accuse cycle. And so k accuse cycles is actually quite a long time (probably years of use for most people).

With that background in mind, here are some tips for getting the near out of your iPad's battery:

Heat tin permanently reduce battery life, especially if you employ your iPad at temperatures higher than 95º F. The cockpit certainly can get that hot, then the best communication is to never leave your iPad in the airplane when y'all're non there and never identify it in the sun. Also, charging the device when it'southward over 95 is even worse, so try to do your charging at dwelling house if you oftentimes fly in hot conditions. Finally, airflow does help so remove your iPad from its case if it'due south getting hot.
Cold conditions (beneath 32º F) tin can also impact battery performance, but this is a temporary issue. Again, you shouldn't shop your iPad in the airplane on a cold night, only once it warms upwardly the battery should give y'all normal life.
Employ your iPad regularly. Lithium-ion batteries are meant to be used hard, then don't be afraid to employ and recharge your iPad often. In fact, if you don't regularly utilize your iPad, you lot should perform a complete accuse cycle in one case a month (where you fully discharge the bombardment, and so charge it upward to 100%).
If yous don't plan to use your iPad for a long time (say, a few months), shop it with about a fifty% charge for best functioning. Storing information technology at 100% isn't ideal, and storing information technology completely expressionless is even worse. The best advice is to charge it to 50%, and then turn the iPad completely off and store information technology in a cool area.
Keep your iPad updated to the latest version of iOS. In addition to the many new features Apple adds when they update their operating organisation, they often include fixes and performance enhancements for the battery. It's a adept idea to e'er have the latest version of iOS.
Adapt screen brightness and wireless radio settings for maximum battery life. If y'all don't demand the screen at max brightness, turn information technology down—this has the most touch on on bombardment drain so if you can stand lower effulgence, practise it. Likewise, if you don't need the LTE data service or Bluetooth in flight, plough these services off (hither'south how). Everything else is fairly modest in impact compared to these two.
Limit background app refresh. Some apps tin can be data hogs fifty-fifty while they aren't running, and this is especially ability-hungry if you're using LTE. Check which apps are enabled past going to Settings > General > Background App Refresh.
If you suspect sub-par battery functioning, the best tip is to use the battery utility in the Settings app to monitor what apps are using battery life. iOS is pretty good near shutting down background apps before they become existent parasites, only it's worth looking at this one time in awhile. We have seen instances where aviation apps nearly completely drained an iPad even after the flight was over and the screen was off. Check to come across which apps are using the well-nigh bombardment, and whether they match your usage patterns.

One choice that'southward available on iPhone isDepression Power Mode.This is a one-touch way to reduce screen brightness, animations, and background app usage. It's a neat option in a pinch, and your phone will prompt y'all well-nigh this when you reach 20%. Someday this might come to iPad, but it's non bachelor at this time.

After two or iii years, lithium-ion batteries eventually lose some of their chapters. A full charge just won't concluding as long as it used to. I downside to the iPad battery is that at that place is no (easy) way to replace information technology in the field. If your battery needs service or replacement, it must be sent back to Apple tree or taken to an Apple service provider. This can be done through Apple, for about $100. Details on their site.
