This is just a rant.
I have droid 3 for about 2 weeks. I notice that D3 life is far worse than D2G. For the same usage pattern of me, I usually got about 4 days out of D2G. But for my D3, I always get less than 2 days of usage.
The culprit seems to be "cell standby" (there was another thread on this). My D2G always got about 5% on "cell standby" however, my D3 always got over 35% of power usage on "Cell Standby".
End of rant.

Cell STANDBY. STANDBY. It means the phone is idling and not being used...

Sounds to me like someone needs to switch Carrier Mode from "Global" to "CDMA".
Unless you severely hack your phone or travel outside of the US, you won't need Global mode.
This prevents the GSM radio from switching on.
Also, Cell Standby will be used frequently when you're in a weak signal area. The best solution to that is to switch cdma mode to "Home Only" and use Wifi if you're using data apps. Strong Wifi uses less battery than weak CDMA.

Actually two days of usage without a charge is pretty good. That's about what I get with my extended battery and fairly lite usage. A couple of possibilities: 1) you now have a dual core cpu which is much faster than your D2G but probably draws more power. 2) You may be using your phone a lot more. I know when I switched my wife from her Droid 1 to her new Droid 3, at first she was complaining of poor battery life. Trying to trace that down I looked at her data usage for the first month she had it and it had more than doubled from about 500 MB on the last month with the Droid 1 to over 1 GB the first month with the droid 3. See, it was her new toy so she was playing with it a lot more than usual - particularly since the phone is faster which allows her to do more with it. We are in the second month now and data usage seems to be getting back to a more normal level.
The point being that when its new, the tendency is to use it a lot - even if its just getting it all set up the way you want.
My several day old HTC One is a fantastic phone (best I have owned yet), but I'm having to be very careful to keep the battery lasting an entire day.
In particular I am noticing that voice calls are the biggest drain on my battery.
2 hours and 20 minutes of talk time used 55% of my battery life yesterday.
I have read multiple sources with tests pegging the talk time at 14 hours+ (AnandTech, HTC official).
Is this typical or is there potentially a software or hardware issue?
I haven't done any serious tweaking to the software, and am running powersaver and have screen dimmed to 30%.
Thanks!
You have to see a lot of thing...
1) You had the full signal for all the calls?
2) Your phone was all time with the idle screen?
3) Did you have 3G or 4G on?
Details
I have three bars usually. I am always in 3G. As far as idle screen sometimes I am browsing while phone call is happening.
Does the strength of the signal effect talk time?
Strength of signal definitely affects the talk time. Also if you put the phone on 2g mode when you are not using data and just talking you will get a better battery life. Check for wakelocks as well. I also discovered when I was using htc sense launcher my app usage was about 89% but now I'm using smart launcher and my app usage is 70% and I'm getting better battery life. I've also disabled the maps coz it has a lot of wake locks.

Also, in my opinion, is the best phone I already had and I have been a iPhone fan for a longue time... With LTE one is very difficult to manage the battery for one day... If you can't charge during the day you are in trouble... Other complain I have is the high temperature on the back if i'm using for a longer time....

The tests for the timings are done with voice calls and no screen on. If your using the screen as well its double trouble

That's really low compared to yours. Also, using the speakers eat up a ton more battery, and if the screen is on as well, well that's another issue
I think I figured it out...
In case anyone else reads this thread, after some testing I think I found out what was causing the huge spike in voice app usage.
I now believe that playing music through the phones speakers counts toward the usage of the voice app.
When I use the speakers, huge battery drain. When I don't it's ok.
Hopefully case closed!
Just throwing this out there... I have a Nexus 5 here has pretty poor battery, mostly when it comes to the screen time. Barely getting 2 hours per charge. In fact, I called google today and they are going to replace it; more on that in a bit.
I've tried stock, CM11, CM11 w/chaos kernel, paranoid w/franco kernel - neither is better than the other.. fter seeing some people on stock + franco and other combinations getting 6-7 hours of screen time it got me thinking. Could we be seeing a set of battery manufacturing defects? Google has already changed the speaker grill and button designs [ironically, my Nexus 5 that was ordered 1 week ago came w/the smaller speaker grill and loose buttons].
However, I'm wondering if there was a bad batch of batteries out there? If I didn't get an exchange from google I was going to pop this phone open and replace the battery with a new one just to prove a point. When I spoke to google today, they thought that a 20% drop in about 30 minutes of use was excessive, which I have to agree.
Ideas? Thoughts?

I'm repeating a post from the battery thread I just made....
[quote name="wdwms" post=51191930]I'm wondering if all the variances in battery life we are seeing could be a sign of a broader issue - a large batch of defective batteries?
opened this thread for thoughts/comments: http://forum.xda-developers.com/showthread.php?t=2686119[/QUOTE]
Nope. Its the variances in usage and settings. Guaranteed.
I got 6 hours screen time plus on my Moto x....always. with no changes whatsoever, my wife gets 4 1/2. Why? 90 percent of my use was tapatalk. Mostly just text. 90 percent of her use is Facebook, mostly images....with text. Images take more power to load than text.
That primary difference in our usage patterns made a consistent hour and half screen time difference. Oh....and she makes a few calls, I barely ever had or made calls.
Sent from my cell phone telephone....
Not meaning to debunk your theory....there are occasional defects....but mostly the huge differences are usage and settings.
The guys getting 6 hours plus screen time usually are running with most services off or frozen. Dim screens. Obviously not gaming much or at all. Not using location services or navigating. These things can make giant differences in battery life.
I suggest getting gsam. And doing a full discharge with it and doing some screen shots at the end. I'm betting if you think you have an issue that can be solved.....or its your particular usage patterns.

I can stand to have location services off for the hour of better SOT. However I can't stand having a dim screen so auto is the way I go! I still get 41/2 to 5 hours SOT!

I was using auto....and yeah, generally it's not to bad....now. I think 4.4.2 improved it....doesn't Jack up to full as much.
Then I saw someone mention "display brightness" app ....its awesome. A little slider always on my screen. Love it!

I get 6 hours screen on time on the reggie. Location left on (high accuracy) and same with Google now. I think the only things I have turned off in Google now are search history and location reporting. NFC off. Auto brightness. I agree with kj its based on your usage. I really only use my phone for tapatalk or texting mainly. Some Facebook (not really too into it) emails and a liiiitle bit of gaming.. I also use custom kernels and slightly undervolt. My phone can take -25 across the board and 675mV at 300mhz. I mostly UV for heating purposes when I game. (Addicted to robot unicorn attack 2 and smash it). Also don't use any kind of tap or swipe to wake (KILLS battery on this phone). Plus I always charge with USB. I read somewhere that lithium ion batteries discharge slower if they are charged with USB as opposed to AC. That and I don't have free A/C slots in my man cave. Just a USB port to from my PlayStation to a qi wireless charger. Yes it takes a while....
your battery life majorly depends on tbe quality of your phone/data connection. really majorly! it can make the difference of just 2-3 sot hours if not such a great signal is around, to 5-6 hours sot if there is a great phone/data signal. and it varies greatly for everyone. also, how you personally use your phone makes a large impact. its also going to vary greatly as we al use our phones differently. and how you set up your phone and which apps you use is going to majorly affect battery. and thats going to vary greatly as well. and there are even more reasons for the large variation in battery life.
Unless you heavily use GPS or voice calls, 2 hours SoT is too low. To get that you probably have a rogue processes preventing the phone from sleeping. In comparison, I've used the phone to game for over 3 hours on a charge.
Once that's out of the way and if you're still not happy with the battery life you're seeing ask yourself: what's running on my phone that I don't really need?
Every frivolous widget, forgotten service, or Google Now card is going to use some amount of battery and they add up on a limited power source.

That's a great point @simms22, don't think people factor into the equation quality of reception. In China on crappy HSPA+ with 1 bar, I'm lucky to get 3-4 SOT. In Los Angeles on an excellent LTE connection I can get 5-6 SOT. So reception adds 2 hrs of SOT in my case.
OP, as I suggested. Get gsam from play store....do a full 100 to very low discharge and lets see what it shows.
Otherwise we're all just guessing.

Do a few screenshots when your battery is fairly low. Don't reboot or gsam resets.
For screens, try main gsam screen, app screen...then click the app screen dropdown, and do time held awake and kernel wakelocks. If you're not rooted, not sure which of these won't work.

My son played some games on the phone and i had to use the phone for work, so i need to restart the test.
Right now i'm at 1d 17h 40m, screentime 3h 28m; GPS off, google now off, hotword off, bluetooth off, wifi on, LTE.
Regardless, in gsam, the time held awake is
System 33s
Battery Monitor Widge Pro 29s
Google Play 18s
Android System 15s
Kernal Wakelogs
"no apps that have consumed the specified...."
I'm going to let the battery run out (at 6% right now); I've disabled wakelock for google play store in App ops; charge it up and then let it run w/out Wifi, and leave it on 3G.. My location is on the edge of LTE so its best to leave it on 3G here
Will post screenshots of that test when completed in the next 24-48hrs

We can look at the screen shots still....but 1day 17hours with 3 and a half hours screen time? That sound pretty darn good to me! LOL
Guys getting 5 hours of screen time and that are usually near 24 hours, it much less. At a day and 17 hours....and that screen time, I'm doubting you have an issue at all.

Keep in mind 3g uses the most battery for your internet condition. WiFi and LTE are more efficient though your low signal on LTE wouldn't help.

That is false. 3g uses less than LTE. Why do you think the Moto G gets such great battery life? LTE is a battery hog. WiFi uses the least power of the 3. Unless your 3g signal is very weak, it will conserve battery life over LTE.

It has been confirmed by users on XDA as well as this test.
http://anandtech.com/show/7517/google-nexus-5-review/3
N5 LTE is more efficient than previous LTE phones due to some Qualcomm tech. Also by being considerably faster than 3G it can finish its task and go idle quicker.
Moto G battery life is mainly due to its considerably less powerful specifications.

I stand corrected. I will do my own test using only 3g tomorrow night. Thanks for the info.

I am skeptical of the signal strength of this phone for a few reasons.
1. Battery life is around 12 hours at best with 2+ SOT
2. Signal is almost 90% yellow in the battery graph.
3. Slightly different, but my Wi-Fi signal seems weak. I cannot pickup a strong Wi-Fi signal when I am about 30 feet from the router with 1 wall.
What speeds should I see with xlte on Verizon?
Mine stays in the yellow as well but I get around 16 hours with 4-5 hours screen on time. Here's my phone and my wife's iPhone 5s side by side in my living room. This phone seems to get better signal than any I have used.
Im actually having this same problem on my gs4. Router signal awful and,battery life is horrible... Moto x comes in tomorrow though! Hope i dont,have this issue agaib... On verizon as well
I doubt this phone is even capable of xlte, but I'll do a speed test in better conditions. I've seen signal top out at 91 and dip back to 57. Mind you -57 dbm is perfect signal. I actually left the gs4 because of the signal issues it had, that's how I got this 10 months in my contract. I haven't had any Wi-Fi issues at all. Except that the cellular radios are integrated,I think the internals are top notch.
