iPhone battery icon yellow. Power saving mode or what the yellow battery indicator on the iPhone indicates. Continuous use of reduced power consumption
The iOS 9 operating system, which debuted on Wednesday, brought with it many innovations. A special role among them is occupied by the low power consumption mode. The technology can add three hours to the standard iPhone usage time. The operating system itself provides an increase in time battery life smartphones for one hour.
Activating the power saving mode disables a number of functions mobile device, the operation of which the user often does not notice. Thus, iOS visual effects are limited and automatic application updates are suspended. In addition, a “throttling mechanism” is activated, which reduces processor power, which also has a positive effect on battery life. This allows you to optimize energy consumption and extend the operating time of the gadget.
How Power Saving Mode Works
iPhone disables some features when you turn on Low Power Mode operating system until the user charges the device. Among the parameters that are influenced by energy saving:
- checking mail;
- background application updates;
- automatic downloads;
- some visual effects;
- auto-blocking time – 30 seconds;
- CPU performance is reduced by 40%.
As noted above, all this is aimed at achieving maximum autonomy for the iPhone. The low consumption mode can provide an increase in operating time of up to three hours.
How to use Power Saving Mode
It is worth keeping in mind that the low power mode does not turn on automatically. To do this, the user must go to the gadget settings, scroll to the “Battery” section, go into it and turn the corresponding toggle switch to the “On” position. iPhone will also prompt you to activate this feature when the charge level drops to a critical 20% and 10%. Energy saving will automatically turn off during iPhone charging upon reaching 80%.
The energy saving mode of operation is determined by two components. First, the green battery icon in the status bar turns yellow. Secondly, even if the user has disabled the display of charge in percentage, it is turned on automatically to improve clarity.
Ways to extend battery life in iOS 9
There are other ways to improve your battery life in iOS 9. The updated Battery section lets you see which apps have used the most battery over the last 24 hours and 5 days. There is also a widget available in the Notification Center that allows you to monitor your paired devices.
In addition to the new power-saving mode, iOS 9 also includes other technologies. The application interaction system has been redesigned for greater efficiency and lower power consumption. Now, if you place your smartphone face down, notifications will not be displayed and thus you can reduce battery consumption.
Should I use power saving mode all the time?
Everyone has their own answer to this question. There are situations when the battery literally melts before our eyes, and there is not a single outlet nearby. At such moments, turning on “Energy Saving Mode” is the only way out. The function may also be useful for those who are not satisfied with the current autonomy of the iPhone. Reduced processor power will not affect making calls, sending mail or surfing the web. If you are ready to manually check incoming mail, you can safely enable the mode.
At the same time, energy saving negatively affects gaming performance, which directly depends on the speed of the processor.
Due to the constant increase in iPhone performance, the battery life of the smartphone has noticeably decreased. Using a power saving mode will help solve this problem, as well as some techniques for optimizing the operation of the device, which will increase its operating time.
What is it and how does it work on iPhone, yellow battery indicator
Power saving mode is a new option that appeared with the release of iOS 9, which allows you to increase the operating time of gadgets. As a result of this mode, the speed of the smartphone decreases in favor of prolonging its operation. It is worth noting that the main functions of the phone, such as receiving calls and messages, will not be affected by turning on the energy-saving mode, but the speed of Internet surfing and gaming performance will be noticeably slower. As experienced users assure Apple technology, who carefully analyzed the operation of this mode, the power of the gadget is reduced by about 30–40%.
When you activate the power-saving mode, the device immediately disables several iOS functions, therefore increasing battery life, and will resume disabled functions only after the device is charged at least 80%. Operating system functions whose operation this mode limits, reducing battery consumption:
Activating low power mode, battery charge will be shown as a percentage
After the user activates it, the indicator displaying the battery charge level turns yellow. This is a very handy feature as it allows the user to differentiate when their device is running in low power mode and when it is in normal mode. In addition, when the energy saving mode is activated, the battery charge level in percentage appears next to it, which is also very convenient, but remove this feature it is forbidden.
How to enable or disable power saving mode on iPhone
You can use the low battery consumption mode in several ways:
Instructions for activating low power mode
You can turn off the power saving mode in exactly the same ways, and it is also worth noting that it turns off automatically when the smartphone is charged to 80%.
Continuous use of reduced power consumption
How often to use the power saving mode on the iPhone is up to each user to decide for themselves. This mode is especially helpful in cases where the battery charge is almost zero and there is no way to charge it, but you need to use your smartphone. Also, some users of Apple products were initially not satisfied with the autonomy of the iPhone, so they constantly turn on the low-power mode.
Reducing the performance of the gadget does not in any way affect the quality of the network when making calls and sending/receiving SMS, as well as using the Internet, but you will have to check incoming messages in in social networks and mail yourself, since push notifications will be disabled while the energy-saving mode is running.

Reducing the auto-locking period
This function can be easily used on minimum value and this will greatly help extend the battery life. After setting the auto-lock period parameter, the smartphone will go into standby mode after the specified time. To set the optimal auto-lock period, go to Settings > General > Auto-lock and set the time.
Reducing the auto-lock period will increase battery autonomy
Bluetooth and Wi-Fi
These modules consume a lot of battery power, so it is better to turn them on only when necessary. To turn off Wi-Fi and Bluetooth, you need to swipe your finger up on the smartphone screen, calling up the control menu, and deactivate these functions.
It is recommended to keep Wi-Fi and Bluetooth turned on only during use
Disable background app updates
It's no secret that there are applications (such as mail, maps and others) that are updated without agreement with the user. Therefore, it is recommended to limit the possibility automatic update for applications. Go to Settings > General > Content Update and manually edit the list of applications that can update themselves.
You can turn off any applications from the list
Parallax effect
There are a number of effects present in the iPhone that do nothing other than look aesthetically pleasing and “beautiful.” Some of them include the app's zoom effect, dynamic wallpaper, and parallax effect. To disable it: “Settings” > “General” > “Universal Access”, then you need to find the “Reduce Motion” function and activate it.
Increasing smartphone autonomy by deactivating Parallax
Repeat reminders for incoming messages
If the user receives a message and does not read it, then after a certain time (usually 1 minute) the smartphone duplicates the sound incoming SMS, notifying that it has not been read. The battery charge is also used. To disable this feature, go to Settings > Notifications > Messages > Repeat Alerts and turn off incoming message reminders from repeating by selecting Never.
One way to save battery power
Disable automatic time adjustment
If the user does not travel very often, then this function is absolutely useless and can be safely abandoned. To do this, you need to disable the “Automatic” item in the “Settings” > “General” > “Date and Time” tab.
Disabling automatic date and time adjustment will significantly extend battery life.
The power saving mode on the iPhone will help every user prolong the life of his smartphone. It actually feels like it extends the battery life of the iPhone.

Surely every owner of an iPhone and iPad has at least once wondered why the battery level indicator turns yellow from time to time. The answer is extremely simple - a yellow indicator means that the device is operating in energy saving mode. What is this and how can I return the usual charge indicator?
What is Power Saving Mode?
It is important to periodically calibrate your lithium-ion battery. Battery calibration does two things: it sets the battery and helps the software calculate the battery life range. Periodically draining and recharging the battery keeps the flow of ions moving in the battery. The material properties of lithium-ion batteries require constant use to maintain peak performance.
With each update, new features are added, some of which affect battery life. Research and experience have proven otherwise. The first step is to completely discharge the battery. This can be accomplished during normal use, but sometimes it may not be an option. After all, you don't want to leave to work with the remaining 2% resource. Sometimes 2% can last for several hours. The best time to drain the battery is when you can go without your device for a few hours, perhaps before bed.
Low Power Mode is a useful feature in iOS that can help extend battery life. When the battery charge is low (20% and below), it automatically suggests changing some settings in order to reduce power consumption (the screen brightness is reduced, notifications of new emails are turned off, the “Hey Siri” function is deactivated, etc.). This mode significantly extends battery life, as indicated by the yellow indicator.
To speed up battery drainage, turn on the flashlight, increase the brightness, and play a video, preferably streaming over the Internet. Once your device turns off due to insufficient battery charge, it is better to leave it for a while. If possible, leave it overnight and don't charge it until the next morning. This isn't always an option, and if it's too awkward, skip this step. Allowing the device to sit overnight will further drain the battery. This is partly due to the fact that there was some battery life left when the power was turned off.
Otherwise, it will shut down without saving its state to secondary storage. Keep it in the charger until it is at least 100% charged. If possible, keep it in charger longer. Keeping the device on the charger after reaching 100% ensures it is fully charged. Two extra hours should do it. It will also generate less heat, which will make your total time autonomous work. Now that your device is fully charged, you must reset it.
Step by Step Battery Calibration
The device will boot and will now be reset. Remove the charging cable while the device is up and running. For some, it may not be possible to complete all of these steps. If your battery life is around 0% and you want to drain it faster, turn on the flashlight, turn up the screen brightness all the way, and play a video, preferably from the Internet. In some cases, calibration can help, but it is not a panacea. Luckily, you can extend the life of your new battery by following a few tips.
- There are no buttons or switches or indicator lights.
- Should not interfere with cellular reception.
Users who want to extend the operating time of their gadget can enable the function themselves whenever they wish. However, iOS offers to activate the power saving mode when the battery charge drops below 20%.
Adding Low Power Mode to Control Center
After all, yellow signifies caution or warning in other areas of our lives. Thanks for reading and don't forget to pay it forward. It's green when it's fully charged, red when it's nearly empty, and white or black at other times, depending on the background color of your screen. In the next tutorial, we'll show you where to find Low Power Mode so you can turn it off and avoid having to click the battery icon. This screen looks like the image below -. Regardless of whether the yellow battery indicator appeared because Low Power Mode was enabled in this pop-up menu or manual method, the method to disable it is the same.
In this case, the indicator turns yellow, causing confusion for some. When connected to a power source, the mode remains active until the battery level reaches 80%, after which it automatically turns off. If the function was activated manually (after 80%), it remains enabled even when the battery is fully charged.
Why did the charging indicator on my iPhone turn yellow?
This will cause the battery to expire faster than if Low Power Mode is enabled. However, you can make some adjustments that will help improve battery life unless you are in low power mode, for example. Open the Settings menu. Scroll down and select the Battery option. Step 3: Click the button to the right of Low Power Mode to turn off the setting. The battery icon should no longer be yellow.
How to disable power saving mode
There are two ways to deactivate the function and get rid of the yellow icon. First, you can put your iPhone on charge and wait until the battery level reaches at least 80%. In this case, the mode will turn off automatically and the indicator will turn green again.
Secondly, you can disable the energy saving mode yourself. To do this, open the section “ Battery" in the application " Settings" and move the lever to the " position off" against " Energy Saving Mode».
As mentioned earlier, you will likely see a decrease in battery life after turning off Low Power Mode.
- Scroll down and select the Battery option.
- Turn off Low Power Mode.
Percent percentage automatically results in a yellow screen
Sometimes it is white, sometimes red, but also black or yellow. We'll tell you when the battery indicator turns yellow and how it turns white again. During the day, it may happen that the battery is drained in the single digit percentage range and the white battery indicator suddenly turns yellow. This turns on when it comes to receiving last minutes. When using 20 percent battery, the first time a message appears, the display will remind you to turn on the power saving mode.
Keep in mind that Low Power Mode significantly extends battery life, and if you don't mind giving up some features, it will allow you to use your iPhone and iPad for much longer. In addition, this mode is the only effective way to increase the battery life of devices running iOS 9 and later.
Anyone who refuses to do so will be reminded of ten and five percent of the battery's power. In this case, the display brightness becomes unavailable, emails are not downloaded automatically, automatic download is suspended and can no longer be activated when called. If you think this mode doesn't have much effect, you should check out Matt Birchler's blog. He learned that with the current saver mode the battery was 38.7% slower, so you're looking at more than a third of the battery life.
Depending on usage, this could mean plus a few hours. You can also activate the power saving mode manually. Go to Settings, tap Battery, and press the Control button to the right to activate the mode. When the battery indicator reaches 80 percent, the mode will automatically turn off unless you manually activated the mode. Don't worry, this is only a power saving mode. Unlimited data packages are rare and usually come with fairly high prices.
Surely every iPhone owner has at least once wondered why the battery level indicator turns yellow from time to time. The answer is extremely simple - a yellow indicator means that the device is working. What is this and how can I return the usual charge indicator?
