How long does the iPhone battery last

If it's new, it's 3 days, and if it's long, it's only 1 day.

The iPhone uses a lithium-ion batteryThe characteristics of lithium-ion batteries determine that his health cannot be maintained to 100%, and his use time can only be extended, generally speaking, it is normal to drop to about 90% within a year. If your mobile phone is not very tablet, it is also possible to reduce it to 98% in a year, how to maintain your battery I say a few points for your reference:

1. Don't adjust the screen brightness to the highest, and the general setting will automatically adjust the brightness.

2. Don't run out of the battery completely, recharge it later, it's best to start charging at 20% and stop charging after charging to 95%, don't overcharge, and don't charge after exhaustion, both of which are damaging to the battery.

3. Enter the battery setting interface, turn on optimized charging, and when the battery level reaches 95, use trickle charging to extend the battery life. This is in Apple's battery usage guide,There are clear prompts in it,And you can turn on this switch directly in the settings,The disadvantage is that the spring will be slower after the last 95%,In general, you don't have to care about this time。

4. Try to minimize unnecessary power on/off, because the power on and off has an impact on the battery, the current of the power on and off will be relatively large, and the mobile phone can be kept on for 24 hours, and this impact is not great.

5. Turn off unnecessary background refresh of the phone, which is the main reason for the power consumption in the background, and it is also the main reason for the heating of the phone, and the heating temperature of the mobile phone is the biggest damage to the battery. The common software that needs to be refreshed in the background is basically chat software, and the others can be turned off completely.

6. Turn off unnecessary push notifications in the system, and the general push notification system screen will light up, which will increase additional power consumption.

The battery life of an Apple phone is affected by a variety of factors, including the frequency of use, the number of times it is charged and discharged, the ambient temperature, and more. Generally speaking, the battery life of an Apple phone should be between 2-3 years under normal use. Here are the detailed answers and related suggestions for the battery life of the Apple phone:

Conventional battery life test standards.

According to Apple's official announcement, the battery life of Apple phones is 500 to 800 cycles, which is significantly reduced after full charge-discharge cycles, which usually takes 2 to 3 years. Of course, the exact timing will vary from person to person.

Factors that affect battery life.

Factors such as the battery capacity, frequency of use, charging method, charging environment, and temperature will all affect the battery life. For example, if you use your phone regularly in hot environments, the battery will be more likely to break than if you use it at lower temperatures.

Ways to extend battery life.

In order to extend the battery life of your iPhone, you can take the following measures:

1) Reduce unnecessary usage as much as possible, such as turning off infrequently used notifications, functions, scheduled tasks, etc.

2) Adjust the regular charging time and method. Apple's official recommendation for the best way to charge is to start charging when the battery level drops below 20% and continue to charge until it is at least 80% before stopping charging.

3) Use your phone in a lower temperature environment, especially when charging. Avoid exposing your phone to high or low temperatures.

In short, the battery life of an Apple phone is closely related to your usage habits. There are a few simple things you can do to extend the life of your battery. Record 123

Now the lithium battery of the mobile phone is basically more than 500 cycles, a cycle is from full power to low power and then to full charge A process called a cycle, converted to normal use, about one and a half years to or two years.

According to Apple's standards, a qualified iPhone battery should maintain at least 80% of its original battery capacity after completing 500 charging cycles. According to the estimation of one charging cycle per day (100% of the power is used up cumulatively), it is normal to lose 1% of the battery every 25 days.

Of course, it is normal to use batteries that will not cost so much, such as timely charging, attention to maintenance, and 80-90% use every day is very normal. According to this estimate, it can generally be considered that a loss of about 1% in a month is within the normal range. If it drops to 98% in two weeks and is not used frequently, it may mean that the health of the battery has been delayed.

1. Battery life: According to official parameters, taking iPhone5 as an example, the battery performance will be reduced by 80% after a complete charge (20% to 100%) 400 times, and the performance will be reduced by 20% every year. The theoretical time of iPhone battery life is about 2-3 years.

If the battery capacity of a smartphone is 1500mAh, the standby current standard is between, and it is used in a normal network environment, the standby time can be calculated by the following methods;

Since the battery must reach a certain voltage in order to keep the mobile phone turned on, there is still residual power after the mobile phone is automatically turned off at low power, generally around 10%, and 10% of the power should be subtracted when calculating;

1500mAh (1-10%) 3ma 1500mAh (1-10%) That is, the standby time is about 450 540 hours;

In the actual use of the mobile phone, it is impossible to be in an ideal standby state, turn on wifi, Bluetooth or GPS for standby, occasionally light up the display screen to see the time, check the short message, make calls**, listen**, and watch movies.

If you want to know your iPhone's battery life, just open your phone's settings.

Step 2: Open the Diagnostics & Usage list and select Send Automatically.

The 2800 in it represents the current maximum battery capacity of 2800mAh, at this time, the battery life of the iPhone 6 Plus after 3 months of use, the factory battery capacity is 2915 mAh, that is, the total capacity of 2800 2915 has been used, which is about 96%.

3 to 5 years depending on individual usage.
