OPPO Mobile Phone Saves Power With This Setting, And The Battery Life Immediately Becomes Longer

The batteries of existing smartphones have shown poor performance more than a year after they were purchased. They need to be charged two or three times a day, and they must carry a power bank with them when going out.

Many people's first reaction is that the battery is old and they have to spend money to replace it.

However, according to the system optimization descriptions released by major mobile phone manufacturers in 2026, the batteries of the vast majority of mobile phones are not durable. This is not because the battery itself is damaged at all, but because the power saving mode is used incorrectly, or even seems to be useless and has no effect.

Some people turn on the power saving mode, but do not turn off the power-consuming programs that secretly run in the background, and do not adjust the corresponding system settings. As a result, the power saving mode is like a fake, and the battery power becomes worse and worse with use.

Today I will explain clearly the latest and most effective mobile phone power saving and battery maintenance methods in 2026. They are expressed in easy-to-understand terms. The operation is simple and can be understood at a glance. After setting up, the battery life will be significantly improved, and the battery can still be used for more than two or three years.

1. Deep power-saving management, don’t just turn on one switch

Many people turn on the power saving mode and think that everything is fine. However, this is not the case. The effect of just turning on this switch is extremely weak and difficult to detect.

Tests jointly conducted by multiple mobile phone manufacturers in 2026 showed that simply turning on the power saving mode can only reduce power consumption by about 10%. However, when paired with corresponding hidden settings, the power consumption can be reduced by more than 40%.

This is why many people turn on the power saving mode, but their mobile phones still consume power quickly and get hot, and the battery is becoming less durable than before.

Regardless of Android or Apple phones, there is an advanced setting hidden in the power saving mode. After the system is updated in 2026, the location of this setting will become more obvious, but many people have not noticed it.

For the power saving settings of OPPO mobile phones, first open the settings, then enter the battery options, then find the power saving mode, and then enter the power saving management interface. Here you need to adjust three aspects: First, adjust the threshold for automatically turning on the power saving mode to 60%. Do not wait until the battery level is lower than 20% before turning it on. Turning it on in advance can reduce battery consumption; secondly, turn on the "Reduce Screen Refresh Rate" function. 60Hz is enough for normal use, and the high refresh rate of 120Hz is particularly power-consuming; thirdly, turn on "Sleep Standby Optimization". When the phone is idle with the screen closed, it will automatically freeze background power-consuming applications.

Users who use Apple mobile phones can find the battery option in the settings, and then find adaptive power in the power mode under it. After turning it on, the phone will automatically reduce the screen brightness and limit background activities.

2. Close background power-stealing applications to save more than half of the power

Many apps, the ones that you don’t see open, are actually refreshing data in the background, receiving notifications, and locating at the same time. This not only consumes power, but also causes the phone to become hot, thereby accelerating the aging of the battery.

This is the most easily overlooked power consumer.

On an Android phone, please open the settings option, then find the application section, and then explore the application startup management items. For those software products that are not commonly used, such as shopping types, game types, and short video categories, all their "automatic management" functions must be turned off, and the "background activity" permission and "self-starting" permission must be manually turned off through operations. Only WeChat, SMS, phone, Alipay and other applications that belong to the necessary needs category are retained.

Open settings on your Apple phone, enter general options, find background app refresh, and directly turn off the main switch, or just keep necessary apps such as WeChat and navigation.

After completing this step, you will find that your phone almost does not lose power when it is on standby overnight.

Many people report that their mobile phones lose more than 20% of their power after being left alone overnight. This is where the problem lies.

Those apps that you don’t use very often are quietly running in the background every day, pushing ads, uploading data, and consuming power every second.

3. Turn off useless notifications and reduce frequent wake-ups of your phone.

Many people's mobile phones ring non-stop all day and all night. The advertisements produced by various software, the promotions carried out, and the information pushed. Every notification will cause the screen to light up and wake up the phone once. A small amount accumulates and a large amount of power is consumed.

After doing this, the phone will not wake up frequently and the screen will not stay on, which can save a lot of power and reduce interference.

In 2026, all mainstream mobile phone manufacturers will regard this function as a core recommended function. This is the most effective way to protect the battery. This is the most worry-free way to protect the battery. There is no other comparable method.

There is such an operation method, which is quite simple: for Android phones, you need to enter the settings option, then find the notification section, and then enter the batch management area, where you will turn off all application notification permissions except WeChat, phone calls, and text messages; for Apple phones, you need to find the notification item in the settings, and then turn off the allowed notification function of non-essential applications one by one.

Don't be afraid of missing important news. People who are really eager to find you will choose to call or send WeChat messages. Those promotional contents pushed by shopping software and information bombarded by news apps. If you miss one of them, it will not have an impact on your life at all.

4. Turn on smart charging protection and the battery will last for two more years.

Many people's batteries age quickly due to long-term incorrect charging behaviors, such as using up the battery until it automatically shuts down, plugging in the battery all night without unplugging it, and charging the battery to 100% every time. These habits will accelerate battery wear.

The phone will learn your daily routine, just like you get up at 7 a.m. every morning. It will automatically pause charging at night when it reaches a certain level, which is 80%. It will then slowly fully charge when it is almost time to wake up. This will prevent the battery from being in a high-voltage state of 100% full charge all night, thereby greatly reducing aging losses. This is the principle of smart charging protection. It is actually very simple.

For OPPO mobile phones, in the settings of this option, enter the battery section, find charging restrictions or adaptive charging in battery health, and then turn it on. For VIVO phones, it is also in the settings. After entering the battery options, in the battery health category, find and enable charging restrictions or adaptive charging.

On Apple phones, enable optimized battery charging in Settings → Battery → Battery Health and Charging.

Xiaomi phones and Huawei phones also have similar functions, usually in the battery settings, called smart charging protection or peak capacity protection.

This function runs completely automatically after being turned on, so you don’t need to worry about anything.

5. Avoid three misunderstandings that damage the battery, which is more important than settings.

In 2026, battery industry experts have repeatedly solemnly emphasized that the life of lithium batteries is not damaged by use, but caused by incorrect use.

The first misunderstanding: Don’t shut down automatically when the battery reaches 0%.

Lithium batteries are afraid of over-discharge and should be charged when the power is less than 20%. If used for a long time until shut down, it will cause irreversible damage to the battery and its lifespan will be directly shortened by half.

Second misunderstanding: Don’t leave the charger plugged in all night.

After charging to a fully charged state, it needs to be unplugged within an hour. If it continues to be plugged in all night, the battery will always remain in a high pressure state of 100%, and its health will decline very quickly.

The third misunderstanding: Don’t use your phone in high temperature environments, and don’t charge and play at the same time.

Hot and high temperatures are the main killer of batteries. In the summer, never leave your phone in the car and let it be exposed to the sun. When your phone is charging, don't play games or shoot videos. Once your phone gets hot, stop using it immediately. Otherwise, the battery will age exponentially.

According to the actual measurement data of many digital laboratories in 2026, if the above five settings are done together, the daily battery life of the mobile phone can be increased by 30% to 50%, the battery aging speed can be reduced by more than 60%, and the battery health can be maintained at more than 80% after three or four years of use.

There is no need to replace the battery or buy a new mobile phone. With just a few simple steps, you can solve the problems of excessive power consumption, overheating, and short battery life.

Many people replace their mobile phones not because their phones are lagging, but because the battery performance is poor and they need to be charged multiple times a day.

In fact, as long as you use the correct methods, make appropriate settings, and avoid existing misunderstandings, your mobile phone battery can be used for three or four years without aging.

How do you usually use the power saving mode of your mobile phone?

Have you ever encountered a situation where the battery becomes more and more useless with more use?
