Hi guys, my WF1000XM4 is draining battery fast, is it hinting that the battery need to be replaced? I have them for about 17 months in use. Anyone done the battery replacement in Sony before? Wondering how much is the cost and will it damage the IP rating. Thanks.

QUOTE(oRoXoRo @ Feb 9 2023, 07:19 AM) having same issue as TS, so no more warranty and they cant repair it for you? Based on my online chat with SONY, it seems they don't provide battery replacement service but they do sell the TWS in loose in case you want to replace it . But I will just wait till newer version release and change to new one, since I know this brand new battery condition can only last me for 1 year plus...

Update*** For those who facing power draining issue, please get your unit check at Sony Service Center as Sony is offering FOC replacement to those affected unit, they will check your serial number and also your unit first before proceed to replace the earbuds, if the problem is your charging case then no FOC replacement will be offered. THIS APPLY TO OUT OF WARRANTY UNIT TOO!

The Lowyat spokesperson said they will replace it for free with a new one no problem. But they advice to go to Lalaport or The Curve to get it replaced, if you want to get it faster. I went to replaced mine at the curve and it takes around 1 week for me to get my replacement unit. As long as it is FOC then I guess worth the wait.

Check the receipt here » Click to show Spoiler - click again to hide... « Edit: The battery so far I've tested in my 3 hours session with it is at 70% left. Pretty good, I wonder if they upgraded the battery or something  The battery life is wayyyy better now with the newer unit, I feel it is even better than the condition when I bought new...probably battery has been upgraded. By the way the new replacement unit also come with 3 months warranty
