Sharing is caring
Read that users all over the world are complaining of battery drain on their iphoes 12, 12 pro and 12 mini. Got info from iphone forums in the US on this issue.
What about iphone 12 users in Malaysia?
My iphone 12 pro does drain quite significantly in idle mode quite fast compared to my iphone 11 pro. So I believe this is a genuine issue. Hopefully it is a sotware bug that can be overcome with updates, not a hrdware problem

2 nights ago, when my phone is on standby mode when i was asleep, my battery drain almost 25%.
Anyways, looked for solution online and i disabled a few settings. Last night, phone was on standby mode for 8 hours, battery drained around 5%. So it's alot better with some of those settings disabled.

Mine is ok now with some adjustment to settings.
Last nite charged by wire to full 100% by 12.00 am and this morning woke up at 5 am, battery still at 99%, on ordinary standby. I think the battery needs a few round of charges to normalize.
