As mentioned above, Apple updates its stock apps every year. This is around the time when Apple introduces its iOS update. The company makes some significant changes and upgrades in the operating system. Moreover, you get more space on your device to store other essential data. Battery Usage lets you know which app consumes how much battery on your iPhone.
This feature was introduced by Apple in iOS 9, and in subsequent software updates, Apple has improved this feature a lot.
To solve the idle battery drain issue, check battery usage on your iPhone. If your iPhone is covered by a warranty, you can get its battery replaced. However, you should go for this as a last resort, when all the above steps fail to give any results.
Not sure about the warranty coverage of your device? My best advice is to disconnect your iPhone from Wi-Fi or Cellular data; use Low Power Mode during the night, and keep the brightness reduced.
When you charge a completely drained iPhone, the battery lasts longer. Share your thoughts and feedback with us in the comment section. Your email address will not be published. Call of Duty Vanguard. Most Downloaded Apps in World.
Netflix Games on iPhones. Lenovo Yoga Tab 11 Review. Samsung Galaxy S21 Series. Moto E For a better inspection, it is a good idea to disconnect the battery and check it on a bench or similar surface. However, before disconnecting the terminals from the battery, you may want to use a memory saver to keep the computer memory alive and other electronic devices settings see the Saving Your Computer Memory box below.
If you don't want to buy a memory saver now, you can use a 9V battery instead. Connect the 9V battery to the car battery terminals before disconnecting the cables. Once you have your car battery on a bench,. If the battery is damaged, replace it. Also, make sure all the hold-down hardware is in place and clean the battery tray.
You can use a memory saver or a 9V battery to preserve your car's memory. For one thing, this keeps you from losing settings on devices like stereos.
Also, on modern vehicles, the car's computer memory obtains information during engine operation from many different system sensors, including ignition timing and injector pulse width, so that it can improve driveability.
If your computer loses this information, the relearning process may take hundreds of miles of engine operation. Corroded, loose or damaged terminals can prevent the alternator from charging the battery.

Basically, the test measures voltage drop between the battery post and its terminal. High voltage drop indicates that the charging system has difficulty supplying adequate charging voltage to the battery. This means in turn that the battery has difficulty supplying power to the starting and fuel injection systems and other circuits during cranking and start up time.
Corroded battery terminals won't allow the starting system to function properly, or the charging system to recharge the battery. Cleaning the battery terminals is a simple procedure.
Use a digital multimeter to test your battery and other systems affecting battery charge. Free maintenance batteries those without removable caps come with a charge indicator test indicator eye that tells you whether your battery is charged green eye , needs a charge no color visible , or the battery needs replacement yellow eye.
The battery voltage test is especially useful on maintenance-free batteries because it can quickly tell you the state of charge and battery condition.
On regular batteries those with removable caps you can do a test using a hydrometer, which can also tell you whether your battery is working see the Hydrometer Test section below. If you get a reading between If you were suspecting a battery problem because you had difficulty starting the engine, or you had problems with another electrical circuit, or the alternator warning light on the dashboard is coming on charging system problems , your problem is not with the battery.
If you get a voltage reading below It's possible you have problems with the battery itself see the "state of charge" table below. Charge the battery and repeat the test. If you get the same readings and problems after charging the battery, you may want to take the battery to a shop for a battery load test.
This is one of the best ways to confirm battery condition. Still, the following tests can shed more light on the condition of your battery before you take your battery to the shop. Continue with the following tests. Photo courtesy of Silverxxx on Wikipedia.
Another quick test you want to do before proceeding is to do a quick charging system check. Make sure both negative and positive battery cables are properly connected and clean. Note that you should get a steady reading. If the reading fluctuates, check the charging system wiring for a loose connection; other possibility is a faulty alternator or voltage regulator.
If your reading is lower or higher than your specification, than you may have a bad voltage regulator. Consult your vehicle repair manual; it might tell you how to do some quick alternator checks. If your battery seems to be in sound physical shape, and has good, clean, tight connections, it is possible the battery is leaking its charge.
This can happen when you allow the battery to accumulate a layer of dirt or acid, especially around the top. This test is simple and quick. And all you need is your voltmeter. Leaving your headlights on or other electrical device after shutting off the engine will discharge your battery.

A parasitic load comes from electrical or electronic devices usually a light or accessory that remain active after you shut off the engine and remove the key from the ignition.
Practically all modern vehicles use a little power after the engine shuts off, for example for the radio, dash clock, alarm, and computer modules. But these small normal parasitic loads can turn into power drainers if you leave your car parked for a few days without starting the engine. Old batteries are more susceptible to this type of power drain than new ones. Also, abnormal parasitic loads may suddenly appear. These come from electrical shorts or worn out devices that cause a circuit to remain live when it shouldn't—a worn-out or bad relay, or a module or switch that causes a load to remain on after you turn off the ignition switch.
If you are not aware of the problem, the parasitic load can drain power off your battery overnight. You can locate many abnormal parasitic loads using a simple method. During this drain test, make sure to keep the doors and trunk closed so that no light bulb or dome light remains on.
Also, loosen the under-hood light bulb to turn it off, if necessary. If you detect a parasitic load, you'll need to have access to the fuse box or power box. If the fuse boxes are located inside the cabin, keep the front door or doors open, but use a clamp or similar device to keep the door switches in the off position. You may want to use a memory saver or connect a 9V battery across the battery terminal for this test see the text box Saving Your Computer Memory above.
If you recently installed or upgraded equipment or modified a circuit, isolate that circuit by pulling its fuse and check amperage draw. A hydrometer can reveal the state of charge and health of your battery. Photo in the Public Domain. Save my name, email, and website in this browser for the next time I comment. Skip to content.
Most of times it remains on although we may not need it that time. Turned on GPS condition drains battery even on situation where display is not on. Exceeded Charging cycle of battery: All the battery of every phone has some charging cycles.
How much battery drain is normal overnight? How do I stop my phone battery from draining overnight? Putting phone on the Airplane mode: Even when your phone is sitting idle it still runs activity like network Cell Standby , putting your phone on airplane mode should be able to show you some changes. To do that, you need to go to your battery usage and check which app is consuming most of your battery and then go to individual app setting and restrict background running for that specific app.
If you are having a system related glitch that causing your battery drain faster it may get solved just after a software update of your phone. Resetting Your Phone: Well, it may not sound like a proper solution, but trust me sometimes resetting your phone could possibly stop the suddenly apparent draining issue.
