- Coconut battery allows for the user to get the most up to date and accurate information about their devices battery life. If you need to check your Iphone's battery, you should try Coconut Battery for iphone. The other night I tried to check my iphone and while opened another battery life app the phone shut down. This is not the level of.
- Here, you'll be able to see the battery life for all of your accessories by way of a battery life icon. If you'd like to see exact readings, go back to the main System Preferences view,.
Over the past few years, manufacturers like Apple and Samsung have regularly delivered higher and higher battery densities, often with minimal increase to product weight or size. Apple was forced to make the iPad 3 slightly heavier and thicker when it introduced its Retina display, but it managed to increase total battery energy [possibly capacity – the terms could be interchangeable here] by 70% while only bumping internal volume up by a fraction of that amount. As we discussed earlier this week, Samsung has dramatically increased the energy density of the Galaxy S4's battery (as has Apple with the iPhone 5), again, without a corresponding leap in volume or weight.
A battery charger. In 'X Marks the Spot' from the first season, the Prof fashions a battery charger out of coconut shells and seawater. In fact, he details the whole process, just in case you want.
But there are signs that this increased energy density may come at a cost. Over at his blog, IfWeAssume, developer Jared Davenport has documented his 2012 MacBook Air's rapidly declining battery life. For the past year, Davenport has taken battery lifespan readings on a minute-by-minute basis, giving him an extremely detailed picture of the laptop's battery health and remaining capacity. The results indicate a battery with a rapidly-declining capability — but that's not the most interesting thing. Graphed against his 2009 MacBook Pro, the rate of decline is stark.

There's actually some reason to think that Davenport may have a bad battery; aggregate data from the website Coconut-Flavour, which tracks battery life on Macs, implies his battery is failing rather more rapidly than it should. But, at the same time, there's also reason to think that the battery work Apple and Samsung have done could easily have a downside. Everyone has heard the phrase 'there's no such thing as a free lunch,' but when it comes to batteries, the physics are particularly unforgiving and the mathematics (particularly when it comes to things like failure rates) get really, really ugly.
Dead synchronicity: tomorrow comes today 1 0 12. The data below is drawn from Coconut Battery Online's database of battery life over time.
It's not hard to see that there's two entirely different curves at work. At 36 months, the Macbook Pro has lost ~10% of its maximum battery capacity. The MacBook Air has lost 10% at 12 months. This may partly reflect different use cases in aggregate, though Davenport notes that he used both systems in precisely the same way.
Apple is extremely tight-lipped about its battery technology, as are the other major vendors. We know that the company has filed for multiple battery patents and considered different methods of boosting performance, but we don't know if those filings, which date to 2009, have actually been used in any shipping hardware.

As such, we're going to talk in general terms. Packing more energy into a battery is actually less an issue than you might think. The real problems start creeping in when you want a battery that can be recharged several hundred times without losing much of its original capacity, fits into a tight space with minimal ventilation, won't suffer thermal runaway, releases no toxic gas, and can't expand when hot. You also want a battery that's relatively resistant to overcharging or complete discharge, though this can be mitigated somewhat by building sophisticated software and charging mechanisms into the underlying equipment.
What a little digging into battery tech shows, however, is that the tradeoffs are rampant. We're used to thinking of battery life in terms of power consumption vs. run time. Designers have to grapple with run time, weight, volume, anode/cathode size, discharge rate, voltage, temperature, and the chemical composition of the battery itself. Discharge temperature deviations that are totally fine with one battery chemistry may create sub-optimal performance with another.
One of the negative consequences of the smartphone boom has a relentless push to iterate on yearly product cycles. The problem with this approach is that it requires very careful timing to ensure that 2014's battery technology improvement that you started researching in 2010 is actually ready for deployment in 2014. If something goes wrong, your company is stuck with a substandard solution compared to its rival — or it has to push out a product that might not quite hit the parameters it wants.
If you're facing the choice between a slightly higher failure rate or shipping with no improvement to key metrics on your yearly refresh cycles, you may choose the first and call the warranty replacements a cost of doing business.

Checking the performance level of your iPhone, or any iOS device for that matter, isn't complicated. In fact, it doesn't even require a visit to the Apple Store.
Keep in mind, Apple isn't actually requiring your battery to fail its test to make you eligible for the $29 replacement. Checking your battery is more for peace of mind than anything else.
If after testing your battery you decide its time to replace it, follow Rick Broida's guide to make the process painless.
Apple Support app
This is by far the easiest way to check on your battery's health. Install the official Apple Support app and sign into your Apple ID if required.
Start a chat session with Apple Support, selecting the phone you want to have tested as the device in question. Once you're connected with a technician, inform him or her you want to know the status of your battery's health.
You will then be walked through the process, which requires going into Settings > Privacy > Analytics. A few seconds later, a report is sent to the representative.
My iPhone X battery passed with flying colors, as expected.
Apple Store
Naturally, the Genius Bar inside an Apple Store has all of the tools and resources required to run a diagnostics test on your phone's battery. You'll need to make an appointment through Apple's Support page and visit the store in person in order for the test to be conducted.
One reason to opt for a visit to the store to run this test is if you have questions beyond testing your battery.
Coconut Battery
If you want more info than a simple pass or fail, or don't feel like talking to Apple Support at all, you can install the third-party app Coconut Battery.
It's important to note, the app is not available in the App Store and installing apps outside of official channels is something you do at your own risk.
Coconut Battery Life Warranty
The free version of Coconut Battery requires the iOS device to be connected to your Mac via a USB cable.
Coconut Battery Ios
After installing the app and granting it permission to run on your Mac, click on the iOS device tab, and look at the design capacity of your battery. Anything under 80-percent and you should take your phone in to have the battery replaced. Video editor enhancer 1 0 63 – editimprove video quality.
