A DISASTER!! After 2 months of waiting and going THREE times to have my headset repaired, they ended up giving me a new one and IT STILL HAS THE SAME BATTERY DRAIN ISSUE. DO NOT BUY THIS HEADSET!! (Im from Argentina)

Really disheartening to hear this. Actually very few complain about the same. But most people have confirmed that after this update their battery drain issue was fixed. Even after the Multi point connectivity update my battery performance is same as before. May be it’s happening with you.

Truth & Solution for sony wf-1000xm4 battery drain: After considerable research I now think I understand the XM4 battery problem. The previous XM3 uses a standard 3.7v 60mAh battery like the Varta CP1254 A3. For additional battery life in the XM4, Sony switched to the new ZeniPower Z55H, which is physically identical but 3.85v 75mAh (higher voltage, 25% greater capacity). My educated guess is that : (a) Sony was unable to get sufficient quantities of the new Z55H early the XM4 production, so instead substituted readily available 3.7v XM3 batteries, and; (b) optimized later versions of XM4 firmware (1.4.2+) for 3.85v batteries. The problem is that firmware optimized for 3.85v batteries could overcharge and permanently damage 3.7v batteries in addition to not estimating charge level correctly. Also, customers with 3.7v batteries would likely always get less than advertised battery life. What Sony should have done was publicize a recall of all XM4 units with battery problems, but instead instituted a secret extended warranty just for those customers complaining about battery problems, likely to minimize bad publicity, lost sales, and repair/replacement costs. If so, that's consumer fraud (a term I do not use lightly). Like the XM3, the XM5 should not have a battery problem like the XM4 unless Sony again substitutes different batteries. p.s. To prevent recurrence of the problem, when replacing batteries in the XM4 it is essential to use 3.85v 75mAh batteries (which are now available on eBay & other websites). Unfortunately, some battery sellers are incorrectly indicating that 3.7v batteries can be used.

Unfortunately made my ears sore
