I tried pming you but it didn't show up as sent in my user CP. Not sure if I have to make a minimum post number before being able to PM. I've been a long time lurker and just recently signed up.
I have a Galaxy Nexus on Verizon. I do live in an area where my phone regularly sits at -90dbm signal. This is very odd as well since I always have full bars of 4g service.
Like all LTE phones, I tend to drop signal every once in a while but it polls verizon often enough that it's back up within 30 seconds.
While I haven't done any 3g on with 4g toggle testing, I am still concerned with my battery life.
I have the extended battery.
The phone runs on a stock 4.04 kernel with essnetially stock 4.04 rom and the radios from the rom (stock?). Here's a link:
I have been going through my BBS dump files for the past 5 days or so and have read this entire thread. I wanted to do as much as possible on my end, so you're not left answering the same questions over and over.
I've done things like disabled sync on stuff I don't need (email is the only thing syncing), use the android stock mail client for my gmail, polling at 30 minute intervals, changing autorun settings, making sure i'm signed out of latitude (never use it), disabled some apps I hardly use (google books, google movies, talk, etc) just so they don't get the bright idea of running, disabled and signed out of google talk, got rid of all of my "battery saving" apps (green power), never use wifi, never use bluetooth, and I toggle GPS when I need it for maps. That's all I remember off the top of my head.
However, my battery life is still absolute crap. I get about equivalent battery life now without green power as I do with green power so I'd say there has been an improvement but......
Sometimes I'll get an awake time of 8 minutes in 4 hours (not too bad, but i know it can be lower), other times, it's 8 minutes in 2 hours. Both of these cases are with the phone simply idle (reboot phone, turn screen off, let it sit to get dump).
I checked my kernel wake locks and the major ones I am getting, modem_usb_gpio_awake and modem_usb_suspend_block I found to be attributed to the sending and receiving of data when the screen is off. Now, I make sure to back out of all of my applications so that they are closed rather than put in background so I'm not sure where this data transfer is coming from. My twitter client polls every 15 minutes. I don't think I should be getting a count of 200+ from these in 2 hours. This seems like a widespread problem across various kernels and rom combinations so i'm not sure what to do.
My alarms seems to be system alarms and nothing really out of the ordinary, except I noticed that email sometimes has a higher count than once every 30 minutes. My guess is the sync but if sync is off, I don't seem to get any emails :/. Also, despite my best efforts to TURN OFF calendar sync completely, it still has an alarm count of 2-10 every time.
Below is my most recent one from last night. I can send a progression of dump files if you'd like as well in another post.
If there are any screenshots you need, I can create another dump file tonight and take screens for you.
I have your command center app if there are any dumps you need from that as well to accompany any BBS dumps.

Some things I noticed in here that are odd:
--Checkin Service (signed out of latitude and location NOT ENABLED, as well as toggling GPS). Further, I have never set any automatic checkin settings and have deleted data and cache from maps numerous times.
--GPS Location Provider (again, all GPS related things OFF)
-- android email alarm (40) would suggest polling every 30 minutes for 20 hours.... not the case)
-- calendar 4 wakeups (sync is off and I have no events/reminders). I have notifications on, but again, no events/reminders. Maybe disabling notifications?
So this dump was 12 minutes in 9 hours. not too terribly bad. but I'm sure it can be better. I'm staring at my most recent log of idle with 1 text and i'm seeing 6 minutes in 2.5 hours. But it's inconclusive since it falls under daily use so i have some texting and email checking in there.
Most of why I really want to get this nailed down is because I remember you mentioning in the thread that you get 4+ hours of screen time, with 14ish total under heavy use like that, on your Nexus. I would love to have that. Any suggestions on what rom and kernel to use are welcome as well.
I'm not vested in one particular kernel or rom.
I'm stuck and unsure of what to do next as everything looks fine to me, but the phone inexplicably drains at 3% an hour with ZERO use.
The odd thing is that CPUSpy will read at 97% deep sleep. However, in the past 2.5 hours, i've dropped 15% battery with 6 minutes of screen use and 12 minutes of awake time total. :/
It seems as though every time I drive somewhere, the battery drains fast. My commute form home to work regularly gives me a 3% battery drop. Could this also have anything to do with the infamous "your battery is lying to you" thing? Most of my commuting happens right after I unplug the phone. I thought the nexus was good about that since the charger didn't trickle, but would actually let the phone drain down to 95% before charging it back to full, while displaying that in real time, thereby making things slightly more accurate.
GPS is off, so i'm unsure why (if at all) it would be polling for location while i'm on the move, thereby draining.
Could it have anything to do with the signal being low, despite having 3-4 bars that is draining it?
If you can, I really do appreciate you taking the time to answer. If you don't have the time and want me to post in the thread, I can do that.
Your BBS app is fantastic! Keep up the awesome work!
