t1w410found the culprit, my battery has swollen. realized when i cleaned it up this afternoon and find out that bottom right corner cracked and unable to tightened. now searching battery replacement in online shop
Same problem occurs since 3 weeks ago in pie latest build 3GB variant. The battery now stand for 12 hours max even in idle state, only regular chatting. Before updating this build able to almost 2 days. WiFi on and data in both sim card off. It is like Doze mode is not running. Waiting for the next Pie update since android 10 is still in beta version (some people say so).
*Another problem happens when I put 2nd sim card, pop up message for 'date and clock unable to sync' always popping out several times in an hour. But it gone after I turned off sync in setting.
