[GMaps]: The battery drain analysis

Hello all,
I just wanted to share my experience with my Nexus Battery drain and Google Maps.
I was always complaining about the horrible battery life of Nexus S compared to my previous devices (Xperia X10, Galaxy S, Desire, Hero, etc... some that I bought, loans, tests, etc..)
IMPORTANT: Since the beginning, my phone had a strict sleep policy (on screen off) and the phone was always awake.
I first remarked the battery drain with my battery status was spotting GMaps and I was right.
Just before going to sleep, I uninstalled it and just get a wonderful battery help:

Any explanations?
Any similar experience?

I never had this problem with my Nexus, I just drained the battery a few times when I first got it so it can calibrate properly, I don't know if you have done this yet.

I don't think a battery calibration would explain a Google Maps battery drain, but yes I did it.
I even wipe battery stats 2 weeks ago at 100% power.

Same behaviour here with Google Maps. I am 99% sure that it's the Latitude that keeps updating my position all the time - although I haven't tested it, yet. Latitude should have had a setting for the position update interval.

[Q] Screen on battery drain?

How much battery does your HTC ONE drain when your screen is on?
Mine drops about 3% every 10 minutes (18% per hour) sitting on the home screen. This means I get only 5 hours (and a bit) screen on time.
Every review out there states 8-9 hours of video playback, but I do not even come close to that.
When the screen is OFF it only drains about 5% for 8 hours (or 0.625% per hour), and this seems very normal to me.
This happens on stock 4.1.2 firmware and on ARHD 12 (4.2.2).
Normally I wouldn't worry about it too much, but the HTC ONE has a non-removable battery so I want to make double sure the battery is ok.
So what say you? Do I experience normal or excessive battery drain with screen on?

Five hours of screen in time is normal for me over an 18 hour day.

[WorkAround] Delayed Notifications Nexus 4

Hello guys, finally i have found a good workaround for this issue which affect most of nexus 4 devices.
Let me explain the scenario : Leave the phone in deep sleep for some minutes and try to send a notification, you will get it delayed. Also you can try to ping your device via Computer, you will notice the ping average very high
Below the workaround. Install this app https://play.google.com/store/apps/details?id=com.gejos.android.wakemyandroidpro
Set it like the screenshots below

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Leave the app active, you will have a wakelock every 29 seconds which wake your phone from death sleep (no notifications), without screen goes on (its an invisible wakelock)
You will notice an improvement in notifications no more delayed more of 60 seconds.
Important This app could drain your battery a bit, but still better to turn off wifi optimization which makes your battery life ****ty and android os in battery stats. Im on hellscore and im getting an awesome battery life with this app (1 day of medium usage) .Try to believe.
Cheers, Xda_Emanuel

Thank You Emanuel. Will try and report back.

M7 always awake after switching to Sense 6.0

I upgraded to sense 6.0 yesterday and now my phone is pretty much always awake, causing massive battery drains. Not sure what the update did to cause this. My phone isnt rooted, so any suggestions on how I can solve this?

Please post some screens from battery monitoring apps (GSAM, BBS) which apps are causing drain and what is causing the wakelocks.

I have had the same problem. I have down loaded screen off wifi off to help with the wifi staying in, but staying awake I have found I have to reboot after pulling it off the charger for my phone to actually go into sleep mode when the screen is off. We shouldn't have to but until it's fixed try that.

I have used ViperOne for my HTC One, With greenify app, I have no wakelocks when my device go into sleep

Same issue for me. Early morning after pulling of the charger, I have to reboot my HTC one m7, else the phone stays in awake mode and drain is higher. With a reboot I get fantastic battery performance.

[Q] Sudden battery drain

I've had this phone for about a week and this is the first instance where my phone has gone down to 10% battery in the matter in 8 hours with what I can only describe is light use. I get a few emails, most of the time it sits with the screen off. I checked the battery stats and saw Android OS at 21% usage followed by Cell Standby and Screen.
I am rooted at 5.0.1 but stock and encrypted. Only mods I have done is DPI at 493 and double tap to wake.
Anyone else experienced this before?

So I've been having that issue the past couple days too. I installed a program called BetterBatteryStats.
Yesterday I fired it up after having about half my battery drain in a matter of a few hours.
I saw that my deep sleep was about 3 hours, my awake was 8 or so hours but my screen on was only about 1 hour. Something was keeping my phone from sleeping.
I went threw and uninstalled everything I could think of that had either updated or been added since it started and now it seems to be sleeping again so I'd look at installed apps and updates.
