For the non-communication terminal, the first preset residual electric quantity can be determined to be zero without the bottom-guaranteed electric quantity of communication.
The video can be a short video with a highlight clip or a long video such as a movie, and for the video played for the first time and at the starting time of playing, the remaining playing time length is equal to the total playing time length of the video; for the video which is not played for the first time, the playing breakpoint can be recorded, and at the starting moment of playing again, the remaining playing time length is equal to the time length from the playing moment corresponding to the playing breakpoint to the playing moment corresponding to the video which is played completely.
The current charge may be calculated according to the following formula:

the power consumption rate is (power at the start time of playing the video-the current power)/(current time corresponding to the current power-the start time). The current time corresponding to the current electric quantity may be a play time; correspondingly, the starting time of playing the video is also the playing time. The current time corresponding to the current electric quantity may be a system time (e.g., beijing time displayed by the terminal); correspondingly, the starting time for playing the video is also the system time. Taking the playing time as an example, the starting time of playing the video is 00:00:00, and the electric quantity at the moment is 20% of the battery capacity; at time 00:05:00, the current capacity is 18% of the battery capacity, and if the battery capacity is 4000mAh, the power consumption rate is (2% × 4000mAh)/5min is 16 mAh/min.

the adjustment multiplying factor is the remaining playing time length/{ (current electric quantity-first preset remaining electric quantity)/electric quantity consumption speed }. Taking the above power consumption speed as 16mAh/min as an example, if the remaining playing time is 40min, the current power is 18% of the battery capacity, and the first preset remaining power is 10% of the battery capacity, the adjustment magnification is 40min/{ (8% of the battery capacity)/(16 mAh/min) }, and if the battery capacity is 4000mAh, the adjustment magnification is 2 times.

According to the video playing method provided by the embodiment of the invention, the playing speed to be adjusted is further determined according to the adjusting multiplying power of the playing speed of the video, and the residual electric quantity of the terminal can be further ensured to be enough for a user to watch the currently played video.
On the basis of the foregoing embodiment, the determining an adjustment magnification of the playing speed of the video based on the remaining playing time, the current electric quantity, the first preset remaining electric quantity, and the electric quantity consumption speed includes:
specifically, the adjustment magnification of the video playing speed is determined according to the following formula:
the adjustment multiplying factor is the remaining playing time length/{ (current electric quantity-first preset remaining electric quantity)/electric quantity consumption speed }. Reference is made to the above description and no further description is made.
According to the video playing method provided by the embodiment of the invention, the adjusting multiplying power of the playing speed of the video is calculated according to a specific formula, so that the playing speed to be adjusted is determined, and further, the residual electric quantity of the terminal can be ensured to be enough for a user to watch the currently played video.

the power consumption rate is (power at a time corresponding to a previous preset period-the current power)/(current time corresponding to the current power-the time corresponding to the previous preset period). Reference is made to the above description and no further description is made.
According to the video playing method provided by the embodiment of the invention, the electric quantity consumption speed is calculated according to the specific formula, the playing speed to be adjusted can be accurately determined, and the condition that the residual electric quantity of the terminal is enough for a user to watch the currently played video can be further ensured.
On the basis of the above embodiment, the video playing method further includes:
if the following preset conditions are met, determining the playing speed of the video to be adjusted based on the power utilization parameters and the video playing parameters:
the preset conditions include: determining that a supported playing time length is less than the remaining playing time length based on the current electric quantity, the electric quantity consumption speed and a second preset remaining electric quantity; and the second preset residual capacity is greater than the first preset residual capacity.
Specifically, the supported play time length may be determined according to the following formula:
{ (the current capacity-a second preset remaining capacity)/the capacity consumption speed };
the second preset residual capacity can be set independently according to actual conditions, and can be understood as early warning electric quantity, namely, the residual capacity value of the terminal for reminding the user aiming at the condition of insufficient electric quantity for the first time can be selected to be 30% of the battery capacity and is larger than the first preset residual capacity. If the current electric quantity is 38% of the battery capacity (corresponding to the time 00:05: 00), the electric quantity consumption speed is 16mAh/min, and the remaining playing time length is 40min, then:
{ (8% × 4000mAh)/(16mAh/min) } 20min <40min, the condition is satisfied, and therefore, from the time point 00:05:00, the adjustment magnification of the playback speed of the video is calculated according to the following formula:
the adjustment magnification is equal to the remaining playing time length/{ (current power-first preset remaining power)/power consumption speed }, equal to 40min/{ (28% × 4000mAh)/(16mAh/min) } equal to 0.57, which is smaller than 1, and therefore, the current playing speed is taken as the playing speed to be adjusted.
If the remaining playing time length is 100min and other parameters are not changed, the adjustment magnification is 1.43, and the value is greater than 1, so that if the current playing speed is 25 frames/s, the playing speed to be adjusted is 1.43 x (25 frames/s) 35.75 frames/s, that is, the video is played according to 35.75 frames/s from the time corresponding to 00:05: 00.

Specifically, referring to the above example, for the case that the remaining playing time is 100min, the video is played at 25 frames/s from the time 00:05:00, and if the current electric quantity reaches 30% × 4000mAh at the time 00:10:00, the adjustment rate of the playing speed of the video is calculated according to the following formula:
the adjustment magnification is equal to the remaining playing time length/{ (current power-first preset remaining power)/power consumption speed }, which is equal to 95min/{ (20% × 4000mAh)/(16mAh/min) } is equal to 1.9, and the value is greater than 1, so that if the current playing speed is 25 frames/s, the playing speed to be adjusted is 1.9 × (25 frames/s) × (47.5 frames/s, that is, the video is played according to 47.5 frames/s from the time when the corresponding time is 00:10: 00.
