Hello guys. I am posting some screenshots from latest miui 3.2.8 Multilanguage. My phone has many wake-ups and more of them are from Google location service although all Google maps location updates and history are set to off. Also weather and Facebook are set to 4 hour intervals checking...
Any feedback?

I cannot understand why screen on time is 36 minutes but my phone was awake more than 2 and a half hours. Why I have so many alarms from Google locator.

It's not just you, I register very similar numbers all across the board, and while for the most part, Deep Sleep (DS) is preferred, I've also noticed that the amount of DS doesn't really affect my battery life much, if at all. Regardless of whether DS is at 80% or 50%, I'm still registering the same overall usage numbers.

Even if DS is 0% for an hour or two and 918 MHz is at nearly 100% (with screen off), my battery wasn't dropping, i.e. 0 %/hr, so I think on screen is the biggest culprit for battery drain regardless of processor usage. I'm on the 3120 mAh battery and for kicks I decided to lower my brightness from 80-85% (this is typically where I have it) to Automatic Brightness all day and with 50% remaining, I've been up for 16.5 hrs (4 hr on screen), so I've managed to improve my numbers by a couple of hours from that one change.

Well maybe this will help:
- turn off Google Now if you dont use it. Google Search will still work
- turn on Auto Brightness
- minimize apps syncing time
- and most important: set other than default Qualcomms msm-dcvs CPU governor. Use ondemand/interactive governor that will allow your phone to downclock to 384Mhz when idle and making phone even less lag.

I got almost 3 hours of screen on and more than 40 hours standby without charge with stock battery.

One thing I've noticed is the default min. CPU speed for my device is always usually 918 MHz. This is on interactive/cfq by default too.
