why "Phone Idle" consumed so much battery? - Optimus One, P500, V Q&A, Help & Troubleshooting

I flashed the 4.4.2 (CM11) according to http://forum.xda-developers.com/showthread.php?t=2589303. I did a battery baseline test:
turn off BT, WIFI, put into air mode, without any apps installed, leave for 3.5 hours, the battery level is down to 85%! I checked the battery usage, the #1 usage is from "Phone Idle"! It consumed more than 50%, the time on "Phone Idle" is almost exact same the the test period, only couple of minute less than 3.5 hours! Why? what process is "Phone Idle"? If it is really idle, why consume battery?

Wakelocks

Any ideas on managing the wakelocks on Android and specifically on the Infinity?
I've checked the option of switching off WiFi with screen-off, but in my battery usage stats I still see that over 10% of battery is consumed by Google Services with 672 wake locks & device waked 77 times (WiFi drain itself is 13,5%, so quite OK). This is what GSam Battery Monitor shows. Android stock battery management (in Settings) shows 51% drain by Google Services and 26% by WiFi (but I believe these stats are wrong most of the time or just measure a different thing, as they show tablet inactive with 2% bar and it has been inactive most of the time actually).
I have google auto-sync on and I need it, but I still think this is too high a number. I don't get 672 e-mails daily, so these shouldn't be PUSH notifications etc.
I'm not sure if I'm the only one seeing these high numbers there?
Have you tried CPUspy for finding out how much time in deep sleep you have?
Better Battery Stats is also a needed tool to find more about wakelocks

Yes, I'm looking at it from time to time, but thanks for this. I had some issues when I started this thread, after wipe and re-flashing new firmware it seems OK in the stats: Deep Sleep 44%, 102MHZ 16%, 1500MHz 24% (running on balanced mode, interactive governor).
I'm still curious to get to know how to manage wakelocks under Android from (low) system level however.

[Q] About Battery Life

Hi,
I have a question regarding battery life of the OPO. I'm still not sure whether I have a defective battery, or some apps drains my battery like crazy (or both?). I hope you can help me with this.
In the first 2 weeks since I got it, I use my OPO for mid to heavy activities (a lot of Whatsapp, Youtube, streaming music, etc). I always start the day with 100% battery and I thought it was normal to see the battery drops to at least 20% at the end of the day. To be honest, I didn't check the battery stats in Settings even once in this time frame, and due to my heavy usage, once again I thought this was normal.
Until one night I decided to plug the charger earlier than usual, unplug it around 11pm (w/ 100% battery), then I fell asleep. I was shocked the next morning (8am) when I saw the battery has decreased to 65% with no activities whatsoever. I check the battery usage in Settings and then saw Google Play Services (GPservice) at the top of the list with 45% usage, with "keep awake" time almost identical to total time on battery. I did some research and found some advice including 1) denying GPservice abilities to "keep awake" and "wake up" via privacy guard (from this thread http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525), 2) turn off location, 3) turn off sync, but none of them seems the solution to my problem. Since then, I always check the battery usage and reset it, to see if GPservice still at the top. Sadly it still there. After I reset the stats, go to sleep directly and check it about 1 hour later, GPservice uses 40% - 60% of the battery usage, draining about 6% battery / hour.
With screen on a few minutes, it easily drops to 5th or 6th place with ~7% usage, with screen and main apps I use on the 1st and 2nd place. When I googled about this using Firefox, that's when I start worrying about something else, the battery itself. With wi-fi and low brightness (less than >20% if I convert it from the slide bar), browsing with Firefox decrease the battery 1% in 2-3 minutes, no or low usage drains 1% in about 5-6 minutes. In contrast, charging increase the battery 1% in 1 minute. Is that normal? IDK, usually bad battery increasing faster when charging and decrease significantly when in use.
Please help, especially about the excessive GPservice battery usage. And if it's possible, I prefer non-root solution for it. Thanks and sorry for my bad English.

Definitely sounds like somethings not right, what apps do you have that access or could potentially access your location? If you're still not having any luck, as a last resort you could try a fresh install of CM11S and install your apps one by one to see if you can determine if any are responsible for sucking battery.
Give the below app a try:

Install Gsam to see if you can gain any more insight into whats causing battery drain.

Maps, Google Fit, Google Now, among other things.
CMIIW but I read somewhere that GServicefix does the same like privacy guard, denying some service to keep awake, wake up, etc.
So I installed Gsam and run it about 1 hour. Interestingly in there, Kernel (Android OS) is on the top the % list with 60% usage (mostly phone in idle/sleep). When I switch sorting to Kernel Wakelocks, it shows event0-798 & event2-798 as the top 2 wakelocks with around 7000 wakelocks. I'll update in few hours, thanks.

From what I read on the Play Store description, Kitkat and above requires root?

Hi, sorry for the late reply.
It seems reboot the phone a few times solves the problem. Battery usage now seems normal when idle, even with location & sync turned on.

whatsapp battery use

I've experienced this on other phones before. Anyone know why whatsapp is such a hog? Mine shows 3.5 hours of use already today AND I have background processing turned off
It never figures significantly in my battery usage, even on days when there's been a long exchange going on. Right now GSam is showing it as having used 0.2% of today's power drain and 45s of cpu (has only been one message today), while the system menus show it has using 0%.

High battery usage in idle?

Hello,
I just noticed that my phone has been using 14% battery in the last 3 hours. It was at 100% before. Battery usage shows that 3% have been used by the ambient display (used 2hrs, 28mins), 2% by the screen (11mins) and 1% by phone idle (2hrs 54mins). Thats 6%. The normal battery usage without the "Show full device usage" option shows 3% ambient display as well and 2% Phone (used 16mins).
Why am I missing 14% of my battery then? What could be the issue? I factory reset the phone last night, I have closed all apps and I have only installed 7 apps (Instagram, Whatsapp, Outlook, TuneIn Radio, Steam, Twitch and my banking app)

Question Best Battery Stats app

OneUI built-in Device Care app doesn't show full details of what is draining battery. It fortunately shows the Screen ON Time (SOT) though.
My phone's battery drains badly on standby. It drains anywhere between 1.5% to 2% per hour on standby if I leave all radios ON. If I turn OFF WiFi, Mobile Data, Bluetooth, Location, etc. then the battery drain reduces to 0.5% per hour. There is no unusual drain when I'm using the phone. If I'm continuously using the phone, I can get 6 to 7 hours SOT.
The built-in battery stats doesn't provide full information on what is draining battery, and how much. For example, it doesn't show system functions like Android System, Android OS, Display, Wakelocks, etc. It only shows 3rd party apps installed.
If I add the % consumption of each app shown in the list, it won't even add up to 50% of actual consumption. If you see the attachment, the sum of the individual consumption adds up to about 20% only. My battery is at 59%. So I have no idea about what used the remaining 21% (standby drain).
Assuming that all details are available in the system, is there an app that can simply read this info and show it on screen? I don't want battery 'monitor' apps that run in the background.
I'm interested to know if there is an app that would simply read this information and display it when launched, and won't run in the background when closed.​
Thanks.
Gsam battery monitor, better battery stats or Battery guru. But i think that they all need to keep a background service, which doesn't cause any noticeable battery drain though

I seriously doubt this. It is just that they don't show up in the stats.
From my experience, there was no difference in idle drain battery usage with and without any of these apps. Checked for some days, not only a few hours.
