How to tell if you need a new iPhone battery



If you have a new iPhone (iPhone 8, 8 Plus, or the much-touted iPhone X), battery problems are the last thing that comes to your mind. But for those with older iPhones, it's probably a good idea, especially after Apple has admitted that it's secretly slowing down its battery life and now offering $ 29 replacement by December 31, 2018.

The slowdown of the battery in older phones is nothing new. Lithium ion batteries are the best option we have for mobile devices today, but they are far from perfect. The longer they go through, the worse their capacity becomes.

Apple's "fix" is why many people with older iPhones report battery problems when a new version of iOS comes out. Not only is iOS written for new devices, but slower on old models (though that's certainly part of it). In fact, in its infinite wisdom, Apple is actually paralyzing older phones, in the name of "overall performance and extending the life of … devices."

It's crazy. Apple was caught, however, as some older iPhones were upgraded after new batteries were introduced and Reddit became public. Weeks later, the company is sued, and the battery change is its PR response.

The $ 29 battery change only applies to the iPhone SE, 6, 6 Plus, 6s, 6s Plus, 7 and 7 Plus. Older phones must be covered by AppleCare, or the replacement of the battery still costs $ 79 ̵

To get a new battery, place an iPhone in the genius bar of the Apple Store or send it to us. But w if you stand on the fence because of the battery of your own iPhone? How can you tell if the capacity is low and has gone through 500 charging cycles – an arbitrary number of Apple for the life of an iPhone battery?

In other words, how can you tell if you need one? Replacement battery?

Checking Wear with an App

The easiest way is to download an app like Battery Life (there are several apps with that name, but this version of RBT Digital seems to be the most robust). ,

The first thing the app will do is display a huge frontpage diagram indicating the battery wear level . Here are three versions that you can compare. The first is on a 2 year old iPhone 6s Plus; The second is a smaller iPhone 6s, which was bought a year ago. The third is an iPhone X that is barely a week old.

  Degree of wear

The degree of wear is the capacity of the battery to hold a charge, compared to its capacity when new. For example, an iPhone X comes with a battery (the X contains two batteries) with a total capacity of 2,716 milliamperes per hour (mAh). According to the battery life app, it still has full capacity. However, the iPhone 6s Plus has a battery that was originally able to hold 2,725 mAh, but now only 2,300 mAh or 84 percent of what it once could handle.


The more you review this app, the more data is saved so you can check if the battery capacity of your iPhone decreases over time. This happens after more and more charge cycles have been used.

A charge cycle occurs every time you discharge 100% of a battery's capacity. It does not have to be completely reduced to 0. If you charge 80 percent of your phone, use it 30 percent and do it twice a day. If you use this 50 percent twice, the charge cycle is complete.

According to Apple, the batteries are suitable for 400 to 500 charging cycles. It usually takes a year or two-or about the time you upgrade your iOS and find that everything slows down when the new iOS detects an outdated battery and reduces processor power to "help" you. It does not hurt that Apple would also prefer to buy a new phone at that time.

With no app, you can see how many charge cycles you've used on an iPhone. (Unless you jailbreak your iPhone.) This may change in 2018. Apple promises an iOS upgrade that "gives users better insight into the state of their iPhone's battery so they can see for themselves if the condition is affecting performance." Until then, the only option is to use the charging cycle of an iPhone Often, you've used a charge cycle for your iPhone's battery, but unfortunately these are the Apple rules.

If developers previously tried to publish an app that measures the iPhone's charging cycle, Apple retrieved it from the App Store. On iOS 10, Apple then retrieved information about charging cycles and battery temperatures so that third-party apps like Battery Life could not access them. Let's hear it for more transparency!

However, there are some desktop programs that you can deal with.


Download on a Mac coconutBattery, which also tells you everything about the condition of the Mac battery.

Connect your iPhone Connect the iPhone to the Mac using the USB-to-Lightning cable and turn on coconutBattery to get a reading on the iOS device tab. The load capacity charts show a list labeled "Cycle Count" so you can see how far you are from the dreaded 500. If you pay for 9.95 USD for coconutBattery Plus, you can connect all this information via Wi-Fi on your Mac, without the iPhone via USB.

It works on iPads too, but iPads are not slowed down by iOS, even when they're older.

Windows users should contact iBackupBot. It works on Windows 7, 8 and 10 and costs $ 35 after a 7-day trial. It is purported to backup all sorts of information from an iOS device on your PC. However, if you connect an iPhone to your PC, run iBackupBot, and create a phone profile, you can also access the "More Information" section, which has a "CycleCount" in the "Battery" section (as well as the original DesignCapacity and the current FullChargeCapacity of the battery.)

HowToGeek reports that you can also contact Apple through the support website to activate the remote control of your iPhone's battery health (albeit without specific numbers) .It is up to you if you are a company trust that has just admitted to paralyzing CPUs just because the batteries are getting old.

When should I buy a new iPhone battery?

Now that you are equipped with the information needed for measuring capacity and even charge cycles: You'll have to decide when to get the new battery.

The following would I suggest: If you have something older than an iPhone 7, get it Next time, you'll need a $ 29 battery change. & # 39; You are near an Apple Store. It costs a couple of hot Venti chocolates and it's worth it to offer these older iPhones another year of decent performance.

If you have an iPhone 7 or later, rarely check the battery life app and see where the journey is headed. If your iPhone battery is only 80 percent charged, you should look at the replacement options, hopefully before Apple's battery deal expires at the end of the year. (Remember, if you have AppleCare and your battery is less than 80 percent of its capacity, it will be replaced for free, or you'll get a replacement iPhone equivalent if something else goes wrong.)

Or buy the battery IFixit kit and do it yourself. It also costs $ 29, but will be available after December 31st. And it works on older iPhones, but not on iPhone 8, 8 Plus or X. The downside is that you need to open the iPhone yourself.
