iPhone 14 Pro / Pro Max There are devices launched about a year ago, being put up for sale from September 16, 2022. At less than a year, many possessors of these phones complain that battery health, the life of the iPhone battery (Maxim Capacity) has been very degraded after decreased from 100%.
Unfortunately this problem is not new. The holders of iPhone 13 mini have faced with similar problems Last year.
Unii posesori de iPhone reclamă faptul că după luni de zile în care capacitatea maximă a bateriei a avut 100%, acest procent a început să scadă brusc, până la 85 & – 90% în doar câteva saptămâni. Unii spun chiar că scăderea este de aproximativ 2 procente pe săptămână. Foarte mult!
As for me, iPhone 14 Pro activated at the end of October 2022, the health of the bath (Maximum Capacity) is still at a 100%percentage.

How do you increase the life of iPhone battery (Maxim Capacity)
Maximum Capacity (Maximum capacity) in the status of the battery of an iPhone refers to how much of the original battery capacity of the device remains functional currently. It is a measure of the degree of battery degradation compared to its original capacity.
For example, if an iPhone had a battery with a 100%initial capacity, but "maximum capacity" now indicates 80%, this means that the battery can only retain about 80%of its original capacity. In other words, the battery has undergone a certain degradation over time and can no longer store as much energy as it was new.
However, Apple says this percentage is not necessarily a cause for concern if it is low. This feature by which users can see the level of battery degradation has been introduced more for the old iPhone devices. Apple also says that:
The energy power needs of the iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max and subsequent models are dynamically monitored, and the performance is managed so that it can respond to these real -time needs. The system is more advanced than previous battery and iPhone battery management systems and allows the phone to reduce the impact on the performance caused by battery aging.
While the impact on performance is reduced as much as possible, battery aging could eventually lead to visible, possibly temporary effects. Depending on the state of the battery and the tasks that your iPhone manages, examples may include longer launch times, lower frames, low wireless data transfer, reducing screen brightness or lower speaker volume.
How can you protect the battery of an iPhone?
Most likely, iPhone 14 Pro / Pro Max users complain that battery health has decreased, use devices in a more intense way and keep functions like “Always On Display“. This is one of the features that lead to a faster battery discharge and its degradation.
The main factors that lead to degradation in a shorter time of iPhone battery are:
1. Excessive rolling of games and applications which requires a lot of graphic and processing resources.
2. Defective loading with feeder and charging cable that are not in line with Apple standards. They either will not transfer enough real energy for loading, or overheat the device.
3. Use during loading. If you use the iPhone while loading it, this can generate additional heat during the loading process.
4. Exposure to heat, especially on the car board and the use of iPhone for GPS / Maps services. The battery will degrade very much, both because of the outside heat and because of the processing resources.
5. use of connections 4G/5G for long periods. It is known that the time of use of the battery of an iPhone is greatly reduced when the mobile internet is used. When connected to a re'a Wi-Fi the consumption of energy resources is significantly lower.
6. “Low Power Mode"When the iPhone has activated Focus"Sleep". As can be seen in the image above, I use this setting. I need neither visual effects nor function Background App Refresh when I sleep. So the iPhone battery will rest with me too.
In conclusion, in order to increase the lifetime of the iPhone battery, a balance between performance and the consumption of energy resources must be held. I am the kind of user who changes the iPhone model at most 2 years old, but they all had good battery performance.
Starting with the operating system iOS 17, Apple introduce StandBy For iPhone. An interesting way, about which I wrote an article, but as far as I realize, this feature will put additional pressure on the battery. Even if the Standby mode only functions when the iPhone is charged and is in the "landscape" position.
