My ROG Phone 5s Pro was over heating and had low battery life from the beginning. When I gave it to the service center the first time, they said they replaced battery and gave it back in 3 days. I doubt if they did anything except for downgrading the firmware. After few days of using again with low battery life the phone died while in sleep the day before it was to be submitted for the repair. This time they said that they had to replace the motherboard and took 15 days. Unfortunately I lost my data. The original issue with the battery still remains and also the rear touch slide is not working anymore and is not even shown in the settings. The battery takes in only 2800 mAh while measured using usb volt and ammeter.
