Is there any harm in keeping iphone in power-saving mode?

There is no harm in turning on the power saving mode all the time, but it will affect the performance of the mobile phone and limit the cpu frequency. Because the power saving mode is turned on, the IOS system will increase battery life by weakening or turning off functions such as mail acquisition, hey Siri, background application refresh, automatic download, Wi-Fi association, and some visual effects.

But just turning on the power saving mode does not necessarily save power. The key points of saving electricity are as follows:

1. Don't install too many applications in the device. Please uninstall useless programs in time.

2. Don't mount too many applications in the background, and get into the habit of cleaning the background regularly.

3, the battery is always used, don't always wait for the battery to run out before charging, or always plug in the charging treasure. These are not good for battery health.

4. Keep the phone cool, don't play with the machine for a long time, and try not to use it when charging. Batteries are afraid of heat, and > 35 degrees Celsius is harmful to battery health.

6, make good use of flight mode, sleep too tired to enable flight mode, both clean and power-saving.

7.Wifi is available at any time (Apple has set up a shortcut switch in the control center for this purpose).

8. Update the versions of IOS system and application software to the latest official version, which will help to save electricity.

Extended data:

IPhone has a built-in lithium battery, but unlike most mobile phones, users can replace the battery themselves. After the iPhone is connected to the computer, it can be charged synchronously from the Dock cable through USB, just like charging the iPod. In addition, USB can be charged directly from the wire connected to the AC power outlet.

For the quality of the iPhone battery, Apple conducted about 400 tests when preparing for production to determine the battery life. Apple's website says that the battery life has been tested after about 400 charging cycles, and its design can maintain 80% of the original total power consumption, which is equivalent to the battery of iPod.

The battery life of the early iPhone has been criticized by some science and technology reporters as insufficient to cope with, which is lower than Apple's statement, which is related to J.

The customer satisfaction survey report conducted by D. Power and Associates also reflects that the satisfaction with "battery" is very low, and the iPhone

The lowest rating of 3G is 2/5.

If the battery fails or dies prematurely during maintenance, users can send their mobile phones back to Apple for free replacement. The maintenance period is within one year from the date of purchase, such as buying apples.

The maintenance period can be extended to two years, and a full service plan is provided. The charge for battery replacement service is based on the user's product launch date, similar to the iPods battery replacement service provided by Apple and third-party companies.

Consumer rights organizations concerned about taxpayers and consumers complain about Apple and AT & amp； Tthe user must pay when replacing the battery. Since July 2007, the third-party battery replacement package has been launched, and the price is cheaper than Apple's battery replacement plan.

Apple applied for a patent in late July of 20 13. Apple is committed to developing a power management system, which provides functions such as improving energy efficiency and estimating the time and distance for users to leave the power supply. Detection function, by adjusting the charging utilization rate, find the most suitable power supply type.
