Strange battery behavior

[yugendra]

Today when I charged my phone i found mysterious behavior of battery on my s24 ultra. My phone got discharged completely. I put it to charge in switched off state. After it charged to 89%, i switched on my phone and started checking the phone.

After 2-3 minutes i found that battery charged to 90% then it started discharging battery to 89 to 88 to 87. Charger was connect all the time and charger was on. Instead of charging charger was discharging the battery. Not sure what else is remained to see.

After removing the charger and plugging in again battery started charging.

Now after reading this post someone from samsung would ask me to shared log file and pretend that they are analysing the issue and after few days they will say it's completely normal and it's a feature of device 😉.

Let me know anyone else face the same issue.

I have wasted my money on this useless device.

I already submitted complaint along with log. The way Samsung work is keep the complaint open for few days then send message that everything is working as expected, there is nothing wrong with the device. Keep using the device. This is the answer i received for other complaints that I raised. They will close the complaint without giving proper resolution.

Dear Samsung Member,

Greetings from Samsung Customer Support!

As per your concern, we would request you to kindly perform the following steps to resolve your issue. However, we are taking your valuable feedback regarding this.

Charge in one go instead of charging many times as it affects the life span of the battery and battery performance

Perform Battery Optimization
Battery optimization helps you to boost the battery performance of your device. To check battery optimization:
Settings > Select Device Maintenance/Device Care/Battery and device care > Optimize > Optimize all options like Battery, Storage, and Memory

Turn off Wi-Fi, GPS, Bluetooth, etc.
Turn off unused functions like Wi-Fi, GPS, Bluetooth, and location settings when not using them: On the home screen swipe down the notification panel > Turn off Wi-Fi, GPS, Bluetooth, and other connectivity features when not using them.

Check device network fluctuation
Kindly check whether the mobile network fluctuates frequently or if the network signal is low in your area. In both cases, the battery will drain considerably fast.
Recommendation: We recommend you avoid using it in areas with low network/fluctuation.

Reduce display brightness level
Kindly set the device display brightness in auto mode (If available).
Adjust screen timeout settings: Settings > Display > Screen timeout > Select minimum screen timeout.

Check and update the App: Kindly check which application or interface is using more battery from device care. And try to update the app or avoid using that app.

Close background running apps
Close all the background running apps when not using them,

Turn off auto sync of e-mails, app data, etc.
We request you turn off the auto sync option, it will stop the synchronization of the device with the server & reduce the battery drainage.
The steps to turn off auto sync are:
1. Swipe down on the home screen to open the notification panel.
2. Turn off the auto sync option.
Check your device in safe mode: https://www.samsung.com/in/support/mobile-devices/safe-mode-on-samsung-phones/

Update the software if available: https://www.samsung.com/in/support/mobile-devices/samsung-galaxy-smartphone-how-to-update-software/

Reset your device: https://www.samsung.com/in/support/mobile-devices/samsung-galaxy-mobile-how-to-perform-a-factory-res...

Except wi-fi, GPS and email auto sync everything else mentioned in the post, i already did. Wi-fi cannot be off as i am using my office apps as well, for the same reason i can't turn off auto sync.

Battery down to 67% from 100% within 3h 22m and SOT is 14 minutes only. Now you can imagine the worst battery life of s24 ultra. Nowadays i have to charge twice in a day after latest updates.
