Charging Issue After Android 15 / One UI 7.0 Update on Galaxy A15

[sam_soong]

Hi everyone,

I’ve been using my Samsung Galaxy A15 (Android 14, One UI 6.0) for a few months without any issues. On June 5, 2025, I received and installed the official Android 15 + One UI 7.0 update. The update installed successfully, and everything seemed perfect at first.

However, starting from June 10, I noticed a serious charging issue:

• Fast charging is unreliable – It charges only for a short time (7–8%) and then stops.

• If I disable fast charging, the phone doesn’t charge at all.

• I’m using the official SamsunS Super Fast Charger and cable.

• I’ve tried restarting the phone, cleaning the USB-C port, testing different chargers – the issue remains.

• Battery usage and charging history show inconsistencies.

• Charging in Safe Mode doesn’t fix it either.

This problem started only after the Android 15 / One UI 7.0 update. There were no such issues before.

Please let me know if anyone else is facing this or if Samsung is aware of this bug. A patch fix or official statement would be really helpful. I’m happy to provide more info if needed.

Thanks.

I too have a the battery drain issue. Makes the phone not fit for purpose.

Leaving the phone untouched on my desk for 5 hours results in the battery going from 79% to 20%. Just sitting still on a table the phone is notably warm. Great for a winter hand warmer but silly as a smart phone

In the past my A15 G6 with its huge battery would run for 2 to 3 DAYS without needing charging. 1/4 days run time when not even being used is not a real product.
