We could say that the least developed part of a smartphone is the battery. In recent years, no major progress has been made in this regard, and the battery has remained an unsolved problem for mobile phone manufacturers. If we are talking about major technological advances in terms of processors, memory and storage media, sensors have appeared Face ID, Toiuch ID and other craziness of this kind, nothing has appeared for the battery to increase its operating period after a charging cycle. I still used the old lithium-ion chemistry, and for a powerful iPhone, it does not last more than a day with moderate use.
The only method by which we can make the battery of an iPhone last longer is to avoid as much as possible the use of applications and services that consume the most energy.
In the top of battery consumption we have:
- display - is one of the largest consumers of energy on any smartphone or laptop. The higher the brightness, the faster the battery will be consumed.
- processor / chipset - processing of complex applications or graphics processing in games requires a lot of energy. Applications such as Facebook or advanced graphics will result in faster battery power. Heating up an iPhone during games indicates that the processor or chipset is very demanding, and it will automatically require more battery power.
- The weak signal on 3G / 4G - If you are in an area with a weak signal, it is best to disable mobile data. In the receiver's attempt to have a steady and stable signal, the battery will be discharged twice faster than in a well-covered area. It is best to use a Wi-Fi network if it is near you. It will drastically reduce your energy consumption.
- Application background activity - "Background App Refresh” helps apps provide you with updated content when you open them, but this function consumes the iPhone's battery even when you're not running those apps. It is advisable to leave "Background App Refresh” only for applications that are really interested in doing this. You can find the option in "Settings”→“General”→“Background App Refresh".
How can we see which applications, games or services consume the most battery on iPhone or iPad (iOS)
After the scandal in which the company Apple is accused that he intentionally modified iOS to reduces battery life and performance of old iPhone models, the company promised that at the beginning of 2018 it will introduce an option in iOS for users to have a detailed report on the state of the battery.
Until that iOS update that we don't know exactly how it will look and what it will show about the battery status, we have it at hand the current report from: “Settings”→“Battery".
iOS: Settings → Battery
In this section, in addition to the possibility of activation / deactivation "Low Power Mode”And display the battery percentage (Battery Percentage), we can also make a stark idea applications and services that consumed the most battery power in the last 24 hours or in the last 7 days.
The report shows the percentage of each application consumed by the battery, and if we click on the sign "watch"On the right, we will see how many minutes it took to reach this percentage displayed next to the application.
That's how we found out that the application "Email” of iOS consumed in the last 24 hours: 20% of the battery for just 1 minute activity with the open and on - screen application 10 activity minutes in background.
Using this information we can optimize your application time si off "Background App Refresh” for applications that have very high consumption in the background. In this way, we will get a longer period of use of the battery after a charging cycle.
At the bottom of this screen we have a report that shows us the times of use and standby since the last full charge of the battery.
4 hours and 54 minutes iPhone was actually used. That is, the screen was open and applications were running, and it was on for 35 hours and 33 minutes, but with the screen closed.
This means that almost a day and a half has passed since the last full charge of the iPhone.
We hope that with the next version of iOS, Apple will expand this report and give users the opportunity to decide for themselves whether or not they want to reduce iPhone performance in order to reduce battery power consumption.
