The iPhone in our possession discharges very quickly compared to the past "> Increase battery life on iPhones, mobile phones and smartphones To check the health of the iPhone battery we can use both the internal menus offered directly by iOS and use some apps dedicated to battery and performance analysis.
If these results are not satisfactory we will show you how to get detailed battery information with a Mac and some programs.
1) Battery check directly from iPhone
The first step is to go to the Settings -> Battery menu (from iPhone 6 onwards) and then check on the Battery Status menu what is reported by the phone itself.
If the battery is still new or evaluated as such, we will report a value between 70% and 100% and in this we will not have to take any measures since the battery performs its task at best.
If, on the other hand, the battery drops below 70%, we can consider it exhausted or in any case too old to be able to hold up for a long time, considering that iPhone will automatically take measures to try to maintain the optimal charge level (decreasing performance or lowering some parameters such as brightness, volume and vibration).
If we see a non-optimal value, we recommend changing the battery at an Apple center or applying energy savings often, so as to extend the life of the battery.
2) App to see battery health on iPhone
If we have a version of iPhone earlier than 6 or in any case we are still not completely convinced of the result obtained "> Battery HD +.
By launching this app we will have a complete report on battery life, the need for continuous charging, the optimizations that we can carry out and the calibrations that may be necessary to obtain the maximum charge again.
Excellent sound alerts integrated with Apple Watch and with the phone, which will allow us to understand in advance if any app is consuming too much battery or if we must immediately charge the iPhone before it is completely discharged.
A good alternative to this app is Battery Life, available for free download from here -> Battery Life .
With this app we will be able to monitor the iPhone apps and services that consume more energy and the amount of charge obtainable, excellent to understand immediately if we need to replace it or the battery still holds up a bit.
This app is much less rich than the one seen previously but it is more useful to understand immediately, without too many frills, if the battery greeting on the iPhone is good or not.
3) Battery check from Mac
If we own an iMac or a MacBook, we can carry out an even more detailed battery check using the console integrated in the operating system.
To use this method we must have an iPhone 6 and later with an operating system updated to iOS 11.3 or later.
We turn on our Mac and, after logging in, connect the iPhone smartphone to the Mac using the appropriate Lightning cable.
Once connected, we click on Launchpad and search for the Console app in the search bar at the top.
Once the system console is open, we click at the top of the search bar and look for the item batteryhealth .
If we have done everything correctly, the BatteryHealth section should appear, accompanied by the wording Good (which indicates a battery in good condition) or the word Bad (battery in poor condition, to be changed as soon as possible).
Nearby we can also find the Max Capacity parameter, which will indicate the percentage of maximum energy that the battery is still able to accumulate with a charge: obviously the higher the value, the more the battery is in good condition (and vice versa very low values indicate a battery to be changed).
Alternatively, we can use an effective program on any Mac (even those prior to the iPhone 6) called Coconut Battery and can be downloaded for free from here -> Coconut Battery .
Download this program on our Mac, start it and go immediately to the iOS Device menu at the top.
If we left the iPhone connected (as seen above), we will immediately show the battery status in the two lines Full Charge Capacity and Design Capacity .
If the two values are too different from each other (for example the Full Charge Capacity bar is 30% lower than the Design Capacity bar) we will have definitive proof that the health of the battery on the iPhone is compromised, so we will have to expect from a moment to other sudden shutdowns, performance drops and so on.
If our situation reflects this scenario and we do not want to change the mobile phone again, we recommend reaching the nearest Apple Store and having the battery replaced: if we are still under warranty, the battery change should be free, otherwise there will be some for the replacement.
