The smartphone Samsung Galaxy A50, released in 2019, still remains a popular device thanks to its high-quality Super AMOLED screen and balanced characteristics. However, time takes its toll: battery capacity decreases over time, and system updates may require more power. Owners often notice that the device discharges faster than in the first months of use.
Fortunately, the software shell One UI offers many tools for optimizing energy consumption. You don't always need to immediately run to a service center to replace the battery. In most cases, proper system setup and changing usage habits can significantly extend battery life. Let's look at effective methods of saving energy.
The first step should always be to analyze usage statistics. The system itself suggests which processes consume the most resources. This allows you to target the problem in a targeted manner, rather than disabling all functions in a row. Understanding exactly where the charge goes is the key to successful optimization.
Analyzing statistics and identifying energy hogs
Before taking radical measures, it is necessary to understand the current situation. The built-in monitoring tools are Android accurate enough for home use. They show not only the charge percentage, but also the time the screen is active in wake mode.
Go to the settings and find the section Device maintenance. Here you will see a detailed breakdown by application. It often turns out that social networks or instant messengers work more actively in the background than it seems. Background activity is the main enemy of the battery in modern smartphones.
Pay attention to the parameter Deep sleep. The system automatically switches rarely used applications to this mode, completely blocking their network activity. You can manually add apps there that do not require instant notifications. This will significantly reduce the load on the processor and radio module.
⚠️ Attention: If you add the messenger to the deep sleep list, notifications from it will only come after manually launching the application. Take this into account when setting up.
It is also worth checking the “Battery Usage” section for the last 24 hours and for the last 7 days. Comparing these periods helps identify anomalies. For example, if yesterday the phone was discharged in 4 hours, and today it holds the charge normally, the problem could be caused by a temporary failure of a specific service.
Optimizing the display and screen settings
The screen is the most energy-consuming element of any smartphone. The model Galaxy A50 has a bright AMOLED display, which at maximum brightness consumes a colossal amount of energy. Reducing the brightness by even 20% can give a noticeable increase in operating time.
Use the function Adaptive brightness, but do not rely on it blindly. Algorithms do not always correctly determine lighting. It is better to manually set the comfortable minimum in the room. In the dark, bright pixels not only drain the battery, but also harm your eyesight.
An important aspect is Screen timeout. Set the display off value to 30 seconds or 1 minute. Many users leave the screen on for 2-3 minutes, which wastes battery power when the phone sits idle in a pocket or on a table.
Turn on the Always-On Screen feature only on a schedule or when you touch it, so you don't waste your battery 24/7 by displaying the clock.
Another effective method is to use a dark theme. Since AMOLED technology illuminates each pixel individually, black on such a screen actually means a pixel is turned off. This saves energy.
- 🌑 Enable the dark theme in the menu
Settings → Screento save system power. - 🔆 Turn off the function to increase brightness in sunny weather if you do not need it is critical.
- ⏱️ Reduce the time before the screen automatically turns off to 30 seconds.
Do not forget about the refresh rate, although in the A50 it is fixed, interface animations also consume resources. In Power Saving mode, the system automatically simplifies visual effects, making transitions less smooth but more economical.
Managing network connections and communications
Searching for a network is a process that forces the smartphone modem to work at its limit. If you are in an area with poor signal reception, the phone constantly increases the transmitter power. This leads to rapid heating of the case and a sharp drop in the charge level.
Check your mobile network settings. If 4G/LTE is not yet available everywhere in your region, and the phone is constantly trying to catch this signal, it is better to force a switch to 3G. Path to setup: Settings → Connections → Mobile networks → Network mode.
It is also worth paying attention to the function Wi-Fi. Constantly searching for available points in the background consumes energy. Disable the “Turn on Wi-Fi automatically” or “Search for networks” option if you do not use this often while on the move.
Bluetooth and GPS (Geolocation) are two more sources of consumption. Many applications request access to your location constantly, even when not in use. Go to the permission settings and select the “Only when using” option for all unnecessary services.
| Function | Recommended mode | Impact on battery |
|---|---|---|
| mobile data | 3G/4G (by zone) | High |
| Wi-Fi | Enabled only at home/office | Medium |
| Bluetooth | Off | Low |
| Geolocation (GPS) | Only when necessary | Very high |
If you are not using headphones or a smartwatch right now, turn off Bluetooth. In a state of constant search for paired devices, the communication module consumes a noticeable current.
Power saving modes and their fine tuning
The shell One UI has several levels of charge protection. Basic power saving mode limits background activity and reduces processor performance. This is often enough for an ordinary day.
Mode Maximum energy saving turns the smartphone into a “dialer”. It disables almost all features, leaving a black interface and basic applications. The screen turns gray and brightness is limited. Use this mode when the charge is critically low (less than 10%) and you need to wait for an important call.
☑️ Setting the economy mode
An interesting feature of Samsung is the ability to configure the automatic activation of saving. You can set a threshold, for example, 30%, upon reaching which the phone itself will switch to a gentle mode. This eliminates the need to monitor the indicator.
In the same section, you can select applications that will work even in austerity mode. Add instant messengers and phone numbers there so you don’t miss contact with loved ones. The remaining apps will be frozen until the mode is exited.
⚠️ Attention: When you turn on the maximum saving mode, some widgets and live wallpapers will stop updating or disappear from the main screen.
Battery calibration and system hygiene
Over time, the power controller may incorrectly display the level charge. The phone may show 15% and suddenly turn off, or hang at 100% for a long time. In such cases, calibration helps. This does not increase the physical capacity, but evens out the readings of the software indicator.
To carry out the procedure, completely discharge the smartphone until it turns off automatically. Then put it on charge in the off state and wait until 100%. After that, turn on the phone without disconnecting the cable and let it stand on charge for another hour. This will help the system recalibrate the values.
It is also important to monitor “digital garbage”. The cache of applications, especially browsers and social networks, can grow to gigabytes. Constant writing and reading of this data loads the drive and processor.
Is it worth using third-party apps for cleaning?
Third-party “cleaners” (Clean Master and analogues) often work in the background and consume more energy than they save. It's better to use Samsung's built-in Device Maintenance tool.
Reboot your device regularly. Once every 3-4 days, a full reboot clears the RAM of frozen processes and resets temporary errors of network modules. This is a simple but effective measure to maintain the health of the system.
Rules for physical operation and charging
The chemical composition of lithium-ion batteries is sensitive to temperature. Overheating is the main enemy of battery longevity. Do not use your phone while charging for heavy tasks such as gaming or filming. This causes double heating: from the charger and from the processor.
Try to keep the charge level in the range from 20% to 80%. Deep discharge to zero and constant charging to 100% accelerate cell degradation. Samsung's battery settings have a function Battery protectionthat limits the charge to 85%.
Use only original cables and power supplies. Cheap analogues can produce unstable voltage, which damages the power controller inside the smartphone. Unstable current leads to additional heating and loss of capacity.
The optimal temperature for charging the Samsung A50 is from +15°C to +25°C. Avoid leaving your phone in the sun or cold.
If you notice that your phone gets warm even when idle, check the list of running applications. Perhaps some application has gotten into an error loop and is constantly loading the processor. In this case, only removing the problematic software or resetting the settings will help.
Frequently asked questions (FAQ)
Why does the Samsung A50 quickly discharge after updating Android?
After a major update, the system indexes files and optimizes applications in the background. This process can take from 1 to 3 days. Usually, battery consumption normalizes on its own after several charging cycles.
Is it harmful to turn on the power saving mode all the time?
No, it is not harmful to the hardware. The mode only programmatically limits performance and background processes. The only negative is that you may later receive notifications from some applications and working on the Internet will be less comfortable due to the reduced brightness.
How to find the actual battery wear on a Samsung?
There is no such information in the standard menu. You can install an application AccuBatterywhich, within a couple of weeks of use, will calculate the real residual capacity in comparison with the factory one (3700 mAh for A50).
Does airplane mode disable charging?
On the contrary, turning on airplane mode speeds up charging, as it turns off all radio modules (GSM, Wi-Fi, Bluetooth), which consume energy even during charging. This is useful if you need to quickly replenish the charge.
Is it possible to replace the battery with a more capacious one yourself?
Theoretically it is possible, but Samsung Galaxy A50 it has a glass back cover glued to a sealant. Replacing it yourself requires skills and tools. In addition, non-original batteries often have inflated declared characteristics, but low quality cells.
