Hi, my 1 month old S4 drains battery like crazy when it is idle. If I unplug it at night, after 8-10 hours I lose over 20% of my battery without touching it! I turn everything off throughout the night, so no wifi, no data, no bluetooth, nothing. I posted some screenshots of my battery. For some reason, according to betterbatterystats, I don't have connection 94% of the time, but I was texting throughout the day and I had full bars every time. Even GSAM says I have signal 100% of the time. But when I look at the kernel wakelocks, the msm_hsic_host one keeps my phone up 100% of the time and no deep sleep at all, it stays at 384 mhz.
Also, according to Gsam battery monitor in the discharge while on/off, it says my phone lost 44% while the screen is off. Is that a bit excessive?
I'm at wit's end with this problem, why isn't my phone going to sleep? Can someone take a look and help me please? thank you for reading this!
sorry I'm very new to this forum so I was not sure how to add multiple pictures, so I just uploaded the link to the album. sorry for any inconveniences!
Here's a good explanation of msm hsic host wakelock
What you may want to try at night is to turn on Airplane mode and check your battery loss the following morning. That should give you a good comparison against the stats you posted in these images. It may help to determine if it's a radio or low signal connection issue.
