Hi ROG Phone 3 users. 

I did purchase a new ROG Phone 3 from ASUS Exclusive Store at Bugis on September 2020. 

I am aware that the phone has a very large battery capacity, 6000 mAh. 

I have been observing the battery life of the phone and noted the battery life’s performance has been performing poorer than expected. 

So, when I did fully charged the phone at 100%, I set the phone to Airplane Mode and leave it as it is for about 7 days. After 7 days I noted the phone’s battery percentage remaining is only between 30% - 40%. 

I compared with another new phone I have, Samsung Galaxy S10 Plus. The phone’s battery capacity is definitely lower than the the battery capacity for ROG Phone 3. However, when fully charged and kept in airplane mode for 7 days, the battery percentage remaining is much higher at more than 80%. 

So, is there an issue with the battery performance of the ROG Phone 3 please?

Please do advise. Thank you.

Try Fully charge both of your phone then play a same video on youtube repeatedly and compare the battery life of both phone.

Hi Devicetextian,
Thank you for the reply. I have not tried doing the suggestion you did advice earlier. However, do you also experience the same issue as I have right now about the ROG Phone 3 battery draining at Airplane Mode? The software update has already been done. Thank you.

I am also having same battery draining issue. When I charge my mobile 100% and kept it a side for over night battery drain happens it becomes 80%. I ahve also tried to keep my mobile in 22% and kept it a side for over night by the morning my mobile got switched off. Battery draining happens after the new update of bypass charging. I have also contacted support they asked me to do total reset of my mobile I have done but it still happens.

My version is 99 only. But battery issue is not fixed. Same happens for me. My mobile got switched off when I kept it a side when it is in 22% and by the morning it got switched off. This updates are the worst fix from asus. Hope asus doesn't have proper testing team. 🤣🤣. They can appoint me as a new test engineer 😎
