    The battery life of my Xiaomi Redmi Note 5 Global has been as extraordinary as reviews predicted until the recent system update to MIUI 9.6.3.0. I haven´t done any measurements to put a number on it, but the change is dramatic. Has anyone else experienced the same?

    Yes over many Xiaomi phones often some updates have a real negative effect on the battery life. But the lastest 2GB update it’s quite bad on my Mi Max 3 too thought it was in my head. That same version I think. First a 290mb update, then the 2GB one to 9.6.2 or 9.6.3 which seems to have killed my battery about 25% faster. I might try a factory reset. I take it it’s almost the same for the Redmi Note 5 (Still have mine so will test)

    But in my experience, Global ROM is always worse for battery life than the Chinese/English ROM.

    Chris, you have probably already noticed, that still another update is now available, including a fix for an issue with battery drain caused by wifi. But I also want to share another possible remedy, that I found by googling. It read somewhere, that a reset of system cache could fix the problem, I tried it and, much to my surprise, there was an immediate improvement. I don´t understand how an excessive cache could cause battery drain even when the phone is idle, but, after all, I am not supposed to understand everything. I have just done the new update and and it will be interesting to see, if there will be even more improvement of battery life.

    Factory reset and update seems to have cured it thankfully.
