How to fix Galaxy A25 battery drain

Charged 100% and it says 15 h 38 m left

It’s frustrating when a new phone doesn't seem to go the distance. For a Samsung Galaxy A25 5G, seeing only 15 hours at 100% usually suggests that either the **Learning Usage Patterns** phase is still active or background apps are working overtime.
Here is a quick checklist to fix the drain:
### 1. Enable "Adaptive Battery"
Go to **Settings > Battery > Adaptive Battery**. This allows the phone to learn your habits and limit power to apps you rarely use.
### 2. Check for "Background Giants"
* Go to **Settings > Battery > View Details**.
* Look for apps with high percentage usage.
* Tap them and select **Limit usage > Put to Deep Sleep**.
### 3. Adjust Display Settings
The A25 has a bright 120Hz screen, which is a power hog.
* **Lower Refresh Rate:** Go to **Settings > Display > Motion Smoothness** and switch to **Standard (60Hz)**.
* **Dark Mode:** Switch to Dark Mode to take advantage of the AMOLED screen, which saves power by turning off black pixels.
### 4. Disable "Always On Display" (AOD)
AOD can drain 1–2% every hour. Turn it off or set it to **"Tap to show"** under **Settings > Lock Screen**.
### 5. Deep Sleep for Unused Apps
Go to **Settings > Battery > Background usage limits** and toggle on **Put unused apps to sleep**.
> **Note:** If your phone is brand new (less than a week old), it is normal to see lower estimates. Samsung’s AI takes about 7–10 days to calibrate to your specific usage before the battery life stabilizes.

Ok, i will try that too

Also, do i wait atleast 7 days or 14?

You should wait at least 7 to 10 days. Samsung’s AI needs this time to learn your usage patterns and calibrate the battery. If you don't see an improvement after two weeks, then you might need to investigate further.

Ok

That estimate seems low for a full charge. Have you checked which apps are consuming the most power in 'Battery usage'? Also, since the Galaxy A25 has a 120Hz display, try switching to 'Standard' smoothness or enabling 'Adaptive Battery' to see if the estimate improves over the next few days
