    This is my problem... The kernel is keeping the phone awake for more than four hours.... Hopefully they release a fix for this.

    Hi guys, I don't know if this will be of any help but it is worth a try.

    I experience battery drain every time I update on my HTC one AT&T version. The problem that happens is that the updater that ATT provides tends to keep looping even after the update is finished.

    I'm not sure how it works on Sprint but on ATT if you check software and there is nothing available it will tell you to wait 24 hours before you try again.

    What I do is go into your date and set it manually a day ahead. After you have done this, check for software updates again. If it says everything is up to date again, go back into your date and set it back to automatic.

    This tends to disrupt the loop of the updater to keep looking for new software and I think the kernel name is redbend if you happen to see it under your wakelock detector.

    Again, I don't know of sprints updater works the same but this works for me every time and it seems it is the only thing that works.

    Only att can push that on the stock rom so simply pop in an at&t sim and your going to have it pushed but if your on 4.2.2 stay the hell away root and flash as you please loki doki dont work on 4.3 or 4.4.2 so you have been warned also kit kat will screw over your sd card and break your gps

    I have the same battery drainage problem. It's the Android system and Exchange services which drains the battery. This has happened to me previously, and then it was the Google Play services which drained the battery. Last time the problem lasted for a couple of days, and then the battery returned to "normal", without my changing any settings or anything. This time, however, the problem won't go away by itself!!! But I still do not see how my changing the location settings or any other settings can fix the problem permanently. This is not the cause of the problem (I know, because I did not mess with any settings before this problem started). So in my opinion, changing settings will only be "symptoms treatment"...

    I'm having the same issue. Rooted stock, somewhat debloated and the HSIC wakelock is eating battery and causing 1/2 the battery life I had before. So far I haven't seen any solution and nothing that I have tried has worked. Luckily, I still have the MF9 bootloader so I can at least go back. MF9 was rock solid for a stock ROM, and really had no issues to speak of.
