Two years ago in iOS 9, the specialists from Cupertino added a useful and necessary thing – the energy-saving mode. At that time, everything was done in the style of Apple – without any adjustments or details regarding the operation of this mode.
Two years have passed and the energy-saving regime still looks like an unfinished chip. At the same time in the camp of competitors this mode really helps, prolonging the battery life of the smartphone at times.
How iOS power saver works
According to Apple’s official information, the power-saving mode affects the following processes:
- disables “Hello, Siri”;
- prevents updates to programs in the background;
- deactivates the automatic download of content;
- removes some visual effects iOS;
- sets the minimum time for automatic locking;
- increases the interval for checking mail.
By simple tests of the performance of the smartphone, it was possible to learn that in the power saving mode, a software reduction in the processor frequency occurs.
Unfortunately, there is simply no way to adjust the mode. But after all, it would be possible to more flexibly control the device and clearly choose how long to extend the operating time without recharging.
I already told you that I chose the iPhone instead. One of the chips that caught your eye in the first place was precisely the pumped-up energy-saving mode. Apple is clearly worth learning and adding several useful options for its own mode.
1. Remaining work time
Based on the statistics of using a smartphone over the past few days, the system can calculate the approximate remaining time. This is very convenient, because it’s much easier to navigate, when instead of an abstract 8% charge you see quite real 2 hours and 15 minutes.
When you apply power saving settings, the system will show how long the gadget will last for certain parameters. You can flexibly turn off the most unnecessary, to get a couple of extra hours or cut everything to use the device for an additional half a day.
2. Energy Saving Profiles
The developers envisaged two energy-saving profiles, each with its own settings. So you can apply a moderate or maximum mode, depending on the situation.
When activated through a special icon in the upper curtain, the last used mode will be activated.
The presence of a pair of profiles allows you to set the parameters of a sparing and maximum power saving, so that each time you do not dig into the system settings.
In addition to its own algorithms and applied parameters, the developers suggested that the user himself change some settings. At the same time, the estimated working time will automatically be changed to a higher or lower side depending on the changes in the settings.
This is not a trivial brightness slider from the settings, but a setting of the deviation of a given brightness level in the current lighting.
You can choose 5 or 10% and the device will continue to adjust the brightness to the current lighting, taking into account the specified deviation.
The flagship Samsung can work with different resolution modes. FullHD + (2220х1080) is the most suitable for everyday work, WQHD + (2960×1440) is useful for use with VR-headsets, and the usual HD + (1480×720) is suitable for energy-saving mode.
The difference will be noticeable only if you look closely at detailed photos, and for everyday usage scenarios, you can specify a minimum resolution, and you will save a charge.
This setting includes software downgrade of the processor to 70%. Maximum power is needed only in resource-intensive processes and games.
The user will hardly notice the difference, and the smartphone will work more for extra 40-50 minutes.
One of the main enemies of the smartphone battery can be turned off with one toggle switch.
This will allow you to use the smartphone to the fullest, but prohibit any activity for minimized programs or games.
Always On Display
One of the chips of Samsung smartphones in practice is quite resource-intensive. Disabling the permanent display of information on the locked device prolongs its operation time by another 5-7%.
4. Maximum power saving mode
There is an emergency power saving mode in the device. It also has all of the above settings, but it has its own peculiarities.
First , you can reduce the performance to 60%.
Secondly , biometric sensors are disabled. The face / iris scanner and the fingerprint sensor will not work, you will have to unlock the smartphone with a password or a graphic key.
Third , the black theme of the design will be applied. It is the predominance of black in the interface that reduces power consumption by an OLED display to a minimum.
Fourthly , the smartphone activates a simplified shell. No widgets, weather informers and other things. All third-party applications will be disabled (standard ones are maximally adapted to work on the device and consume a minimum of energy).
The top flagship turns into a kind of simple smartphone with a minimum of programs and settings, but this reincarnation allows you to achieve stunning results.
5. Lack of automatic shutdown mode
Apple in its style decides for users when it is necessary to turn off the power saving mode. This occurs after a battery charge of up to 80%. Why not make a switch to automatically turn off power saving or prevent the user from setting its own threshold?
For example, the user recharged the smartphone in a cafe or from PowerBank, but was not yet at home near the outlet. In this case, you have to turn on the power saving mode again.
And if you went on a business trip or travel and need a week to save the charge of a smartphone and an external battery, you have to re-enable the rescue mode every day.
The result in figures
Here is a real example of the energy saving mode.
With the remaining 10% of the battery charge, the device is going to work 3 hours and 15 minutes .
After the inclusion of a moderate power-saving mode, you can get almost an hour of additional work time ( 4 hours 2 minutes ), which is almost 25% more than the initial one. This is achieved by reducing the brightness, reducing the resolution, reducing performance and disabling network activity.
A good result, considering that the smartphone remains fully operational. Suitable when delaying for an hour from work or just a device ahead of time began to ask for charging.
Most striking is the mode of maximum energy saving.
10 hours work instead of 3 hours and 15 minutes . Here, the problem was not reduced by brightness, resolution and performance. The smartphone uses a dark interface theme, a simplified shell and disables third-party applications. At the same time, there is a standard browser, a dialer and an email client, there is a calendar, Skype and a camera. Quite enough for most tasks.
Of course, 10 hours the device is only available in standby mode, with calls and outputs to the network it will be possible to squeeze out 6-7 hours, which is at least twice the original rate. It’s almost a full day at 10% charge!
IPhone can only envy such a regime of energy conservation. But there are no complicated technologies and developments here, banal deactivation of functions with manual settings.
That’s what iOS lacks.
