Hi All, I have been using the Xda for long time and I am a bit greed and I never register, yep that's right, hate plz come.
But anyway, I have used too many phones that I can't even remember.
Last couples of week, I got rid off my Nexus one and got A Razr, but the disparagement start right with the battery life!
First a few days, I was using only wifi, as one of my number does not has Web pack on it, and I notice a horrible battery performance on the device and I am
Later on, I activied my internet on phone and here comes my theory.
I notice the Wifi is always running for some reason on the background even if I set it as turn of when screen off, when I check the battery usage, it shows almost every second that wifi is on. That should not be right, it should turn it self off when screen off, and it is not doing that.
Second of all, later on, I noticed something like *WIFI* shows under battery usage, and I was thinking what the heck is that, cause there is another "WIFI" still showing, and also something called" .com.motorola.contact. something like that is waking the phone and using the wifi as well.
And there also something like"motorola.home" running and using wifi for ages. Very strange.
OK, then I went out today, yes, I most of the time stay @ home, na I am joking..
I am mostly in a place with WIFI, home, work place, and Uni. All wifi here and there. Today, I took train 3 hrs total out and back from Birmingham to London for those who like stories. it was 1:30 afternoon battery @ 80% then I listen to music for 1 hr and use whatsapp quite a bit(battery hunger app even on iOS)
On the way back I played GTA 3 for one good hour. and it is now 9PM, and 15% left, as later on I tweet a bit, web a bit. which is good, also I took underground so signal is not always there.
After all these my question is for those who had the battery drain, are U in a wifi enviornment quite a bit time and use wifi?
If so, set the wifi sleep policy to Never(this actually will help) and while not using wifi to use heavy data stuff, turn it OFF and see what happen.
Also turn off GPS espically if you have facebook on phone and also the using wirelsess connection for location, turn that off as well.
BTW the GPS on Razr is reallllllly fast on location, it took 5 second to find me from cold boot. Awesome.
And I don't use task killer or smart action, I think using sensor and active these sensor to save battery while they are using a lot juice is not so smart.
BTW: due to I am on and off subway, my iPhone4s dropped a good 15% without any use, it just sitting in my pocket. (as for now, Android is the fun bit, iOS is the backup, as it does hold battery better a bit...lol)
I am on 2.3.6 (651.167.19.XT910.retail.en.EU)
I flash the rom couple of times, it all shows me WIFI is doing some strange thing.
Today still draining and I use a data usage checker and find that moto blur is using a hug a mount of data, WTF!?
I find battery performance vastly better on wifi than 3G. Mine has had atrociously bad battery life recently, so I'm backtracking through stock ROMs to see if I can replicate the setup I got 5+ hours of screen-on time with.
Gotta love those updates. The sooner data works properly in custom ICS ROMs for the XT912, the better.

I've been using SetCPU to create profiles on the ondemand governor and extrapolating from my general usage during commute, news/texts/im, fair amount of screen on time, I'm getting around 10% drain per hour which is fairly nice. With screen off and 3g running leaving the phone to idle, it drops to around 3-4% per hour which is significantly better from what I was getting right out of the box.
Battery test for Motorola RAZR XT910
Yesterday I decided to do a simple test with my new smartphone, a Motorola RAZR, I shall not charge until he get just 15% of battery remaining. So here I will put the results and thoughts about it.
8:00 AM: I woke up and took XT910 off the charger. Wi-fi was turned on;
8:00 - 9:00 AM: I passed one hour using Pulse to read some news, once or twice I shared some news in the Twitter and Facebook, with the Wi-fi on, of course. The Battery got 85%;
9:00 - 10:00 AM: I started to use Whatsapp to chat with a buddy, took at least 45 minutes of intensive use, battery got 70%;
10:00 - 11:00 AM: Cellphone in stand-by, BUT with the wi-fi on, waiting for someone, battery got 60% yet!;
11:00 - 12:00 AM: That one appeared, so I used Whatsapp again for 30 minutes, and battery got 50%;
12:00 AM - 2:00 PM: Two hours with the cells blocked, but still with wireless connection, 40%;
2:00 PM – 4:00 PM: Motorola in stand-by, now with the wi-fi turned off, so, in the first hour, he keep 40% and in the second, he got 30%;
4:00 PM – 5:15 PM: The final test, I passed just one hour playing Ceramic Destroyer without stopping, the battery got 15% and then the phone asked for charging!;
Well, the battery last for 8 hours with wi-fi turned on almost all time, so I think it's was fair, BUT, the battery status is a bit fake, I don't think that the information was correct, but, it works when is a simple test, you know, right?
We all know about the 1,2 Ghz processor, this drains a lot of battery, but the real villain is the connection, wi-fi or 3G, they both spend so much energy of the cel.
My last thought is... always charge your phone when it's possible, even if you don't use in an intensive form, I hope that you'll not have problems because a low-batterys cell phone.
One thing I've found is that when my battery is draining like a tub it's has nothing to do with any data connection. In running apps there's a media process that keeps my phone running at full bore. If I just kill that I get dramatically better battery life. Normally when I don't have to deal with that I can last all day with a quick touch up charge during the middle of the day. This on my xt912.

your right, certain apps can affect battery life so it is ok to kill running task. however just want to make sure other users know that using task killer to constantly kill many apps is not a good idea! most of the apps will prob restart and this cycle will only drain your battery more. whatsapp is a good example, even they state on their homepage you should remove from task killing as battery would drain not just from the constant restart of the app but also the fact that it would continue to regain connection to their server whenever it restarts.
try use a dark colour like black as you know white colour drains much more battery. if your a constant user of google (maybe even if its your homepage too) try use the black google version. save some battery.
i think personally for me 3g uses more battery than wifi. another factor is the network bars that drains battery if low as constantly hanging onto that low connection.
you should try flight mode and see how the battery fairs there so you can get a rough idea.
also come across an app called FreshNetwork which is a signal booster & finder. Android Market - 4.7 out of 5 Star overall rating! (9,152) as i speak, and it does work.. theres been times where ive had 1 bar connections but after using it i get like 3/4bars. so it helps ease the battery drain there as connection is much better.
hope its of some help guys!!
I know theres is some apps that drains battery, one tip is just deactive the auto-sync with your accounts, other thing, I want a batterystatus app, to know better that stuff.
And I will try this connection app, thanks

Man I even turned off my smart actions, so far I only turn on things when I am really using them. Auto-sync only with wifi!

hey first of all nice site secondly your tips are pretty much on the dot.. just thought of these apps people might find useful
autostarts - helps with disabling apps from auto starting when phone boots up (may be slightly speed up boot?) & also prevent certain app event triggers (maybe an app permission u aint happy with?)
FreshNetwork - helps locate better signals in which in return would improve battery life

If you are getting great battery life will you post your kernel, firmware, and ROM please? Please post if you are on Ext Batt or not.
Thanks
I have an extended battery and I think my battery life is really good. Primarily, I turn off most automatic syncing and keep my screen turned down as low as possible at all times. I use a widget called Brightness Level and I keep it at 13% most of the time. I also keep GPS, Bluetooth, and WiFi off unless I specifically need them. Other than that, I'm not doing anything special. I'm on Clean ROM 4.5 Standard.

I think the biggest culprit is the screen. I'll get varying battery life every day, anywhere from 2 to 12 hours on a standard battery, or 4 to 30 hours on extended.
The only common factor in each of these for me is screen-on time. I'll get 1.5-2 hours on standard or 3.5-4.5 on the extended battery before it dies.
However, as previously mentioned, turning off Bluetooth, wifi, GPS, mobile data, and sync will always help battery life. Too bad I rely heavily on some form of data, email, and Bluetooth headsets for my work.

All in my sig.
I've got a system...
I usually can get through the day with a regular battery; a few things to remember:
1) Mail/messaging/anything push
if you can deal with it, set peak hours from like 7am to 7pm and get stuff every two hours during peak and every four hours during off-peak. Push means your phone is actively waiting or doing something almost all the time. This one single thing will make the biggest difference, except for...
2) The Display
The biggest energy hog of all. Actually not much you can do here but set it to time out quickly (a minute or less) and set to either auto brightness or remember to turn it down indoors.
3) Audio
Running audio through the speakers also uses more battery. Try headphones.
Bluetooth audio is great but again bluetooth also uses more energy than headphones.
4) Networking startup services
Lots of games install startup services that run constantly in the background checking for data from the mothership and/or other players. Get rid of them or turn them off if you can. Some apps also do this, I dont have a list but a little Googling will enlighten you.
Any other tips? I'm always looking for other (reasonable) ways to save battery.
PS: as you probably know, the phone (and any smartphone) will charge about %500 faster if its completely turned off. Common sense, I know, but you'd be surprised...
this will keep you going all day:
http://www.amazon.com/Xantrex-XPowe...IC/ref=sr_1_12?ie=UTF8&qid=1337500958&sr=8-12
Seriously though, if you actually use your phone throughout the day, its probably better to just get the extended battery. Anytime you turn the screen on, it sucks battery.
You can try juice defender. I have it set to extreme and tell it which apps can turn on data with and without screen on, so 4g is only on when it needs to be.
I've heard ROM toolbox can keep apps from opening in the background but haven't paid for it yet. This would be good for games like draw something and WWF that seem to suck power constantly.
Thanks for the replies. I changed my power from performance to normal and that made a big difference because the phone won't sleep in performance mode. Just a note it will still sleep data even though my hotmail is on push. I am using the hotmail app not the htc mail app. I see people with 3+ hours of battery life in the battery thread and I don't see how they do it. I have the extended and I can make it through a day but I only use the screen for under an hour it seems. I'm not really seeing anything new in here I'm not doing but I do keep my screen auto a lot so I might jack that down. I keep every feature off when not in use.
I'm using stock rooted 3.14.605.5 with same firmware and over been getting better battery life since flashing.
I'm mad as hell about losing unlimited data!

Man, That's some serious ****
I generally get great battery life-around 4 hours screen on, 4g, gps. However, a few days ago I noticed higher than normal temps, and poor battery life.
So what changed?
I traced it to the installation of one free app. Picsart-uninstalled and everything is peachy again.
This is my second rezound, the first one always ran hot and drained the battery.
If you're having problems with heat and drain, run a full ruu and see if it helps, if not you may have a bad device or possibly a bad sim. I don't think that the device is the problem in most situations. More likely a runaway app, bad radio/firmware/build combo, user error, or expectations too high.
My setup:
Latest ruu-cleanrom de 1.4-take it easy on the apps and widgets!

Your issue may lay mostly in poor reception. I notice your signal strength thing is in yellow most of the time. Use WiFi if you can. I get pretty good battery life on
Ineffibilis GB
Feb OTA firmware. Don't remember the numbers.
Dsb 1.1.3 undervolted by about 100mv via incredicontrol (UV depends on the device, each is diff) and under clocked to 1188mhz and with interactive governor.
I think my power setting is on Normal.
Also I have weather sync every 3 hrs. Facebook every 4 and leave my Gmail accounts on sync.
I get between 3.5 and 5 hours every day of screen on time through out the day if I'm using my phone a lot. This would also be coupled with usually around 30 minutes of phone calls too. But usually I only charge it every other day (when it gets to around 30%). I get more time out of it on WiFi (5+ hrs and less on 4G (3.5 to 4 hrs at most throughout the day). I also never run my phone down to less than 20% if I can help it. I'm on stock battery too

That battery life isn't great if you're only using 9m of screen on time. 60% after 5 hours isn't unusual for me if I have medium usage of my phone. Like platinum mentioned, your signal is terrible. The Rezound (and most phones) tend to use a lot of battery if they're trying to constantly find a signal.
Right. Battery should only drop 1 to 2 percent per hour on good signal. Bad signal can kill it... If I was on 3G my phone would be around the mid 90s with the same usage.

Does it matter if I turn off data or it will still drain looking for cell signal?
As long as you don't have partial wake issues, there are only two real concerns for battery.
It's not processor. Again, if the phone's not 'awake' while the screen is off, your phone's processor is not ramping up to full speed at all. While it's on and in your hand, 1.5ghz is a great speed for it to operate. Slower speeds than that significantly slow down how your phone operates, and you will have your screen on for seconds longer (Which uses WAY more battery than the higher clock speed).
In Facebook app, go to menu > settings > and change the refresh interval to NEVER!!!
As of Android 2.2, Facebook does push notifications. You don't need Facebook refreshing very 4 hours (OR EVER!). This wakes up your phone (ramps up processor speed, and so on), uses data (battery), and is unnecessary (since you get push notifications anyway). Turn that crap off. Same with Twitter. Turn it down to manual refreshing only (look in settings > accounts and sync as well as in the app). Same with Friendstream (which will automatically have its own refresh settings - fix them).
There are two things that use your battery.
1 - Screen. Turn your screen off when you're not using it. Stop turning your screen on every 12 minutes to 'see if you have any notifications'. Trust the green LED blinking light, or listen for your phone. You can stop checking it. You're using a TON of battery lighting up that 4.3" screen AND waking the phone back up (ramping up the processor, among other things, and it will stay awake for at least minutes, even after the screen goes back off).
2 - Data. Turn wifi off if you're not using it. Turn Mobile Network (GASP!) off when you're not using it. Pull down your notifications and hit Quick Settings, and turn Mobile Network off. Don't have that? Make the HTC Widget > settings > Mobile network. Turn it off when you're out with your friends after midnight. a) you're not going to post anything reasonable or coherent when you're out drinking anyway to Facebook, and b) call and text still works, so you can still mack on honeys all night (and text them drunkenly). You don't need your damn Gmail at 1am. I know you don't. Don't try to convince me otherwise.
If you keep your screen time to a minimum (and brightness down if you're not using auto brightness), and TURN OFF mobile network (internet) when not using it, your battery will last DAYS. Yes, the stock battery. Now, do you do 100+ texts per day? Sorry, your battery is going to die today. And tomorrow. Every day. The screen time murders the battery, and the Wake time that your phone will have as a result (like every time the phone lights up - for minutes at a time, it'll stay 'awake').
That's how you keep your battery going. On any android phone. Yes, an extended battery works great. I bought one (half price in a verizon store) AND got an EXTRA one for $4 (on amazon.com). Yes, it's for thunderbolt, but YES it's the same part number. It's running my phone right now. Keep it charged, and in your glove compartment. Your life will be better.
http://www.amazon.com/dp/B0055OTNK4/ref=pe_175190_21431760_C1_cs_sce_3p_dp_1
Go get it. Turn off your internet, and your screen. Trust your LED notification light. Stop using MMS Screen On. Your battery will last all day, every day. Unless you text a lot. Then, good luck.

In short, yes.
If u turn off data it will help. But you will still have poor signal, so Idk how much it will help. apps and processes that use background data won't be using it, that alone will keep your phone from reconnecting so much, so it will help.
It takes your phone longer to connect on poor signals and your speeds are slower so it takes longer to do the same things. This also keeps your processor running faster for longer times.
what are others thoughts on some of the pros and cons of this update? i'm thinking it will actually save battery to have wifi 'always on' in standby mode rather than repeatedly switching between a on/off state which uses more energy.
It will definitely eat more battery if it's always on under the lockscreen...
Also there is an option to deactivate notifications when new wifi hotspots are around.. if you are about battery life you should deactivate this..

I keep my Wifi always on because it consumes the least battery (vs 3G, LTE, etc).
If I don't play games on my Lumia 920 the battery can last 3 days.
This update is freezing my phone Dunno why but I have tested it. I occasionally get a freeze now and then, but when the keep wifi is on, it is like every couple of hrs... Will test it more though.

Wrong unless your phone is using 5-year old wifi chip.
Correct me if I am wrong, but is the wifi on this phone an on demand type system? From what I see on mine, the wifi unless being used for an actual update or downloading other content goes to sleep when the lock screen is on. It then wakes up if there is an update pushed to it or if something else needs it or of course if you unlock the phone. At least that is the way it appears that mine works.
Also your radio service are going to use much more power than the wifi will as they are higher power transmitters and receivers. There is a reason wifi only works within a few hundred feet and radio works for several miles that is due to the power difference. Of course with more power you get more battery consumption.
In the case of conserving the battery you are better off to use wifi when possible, leave it on and let the phone control it.
In my experience keeping Wifi on permanently lead to a remarkable decrease in battery life. That will depend on where you are though. If I have it sitting at home where it has Wifi connectivity it's likely that I would see better battery life because all actual transfers will happen via Wifi. At work though it can't connect to the Wifi network (private phone, work network) and so I have 3G running anyway while the phone keeps looking for Wifi networks to connect to.
The problem boils down to the fact that while you can switch off Wifi completely because everything can still work using 3G you can't switch off the phone part completely because only data is done over Wifi but you still need the mobile connection to receive calls/SMS.
I would suggest to anyone to simply try out what works better for them. For me it worked best to let Wifi deactivate automatically as it had been the default in WP since WP7 came out.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...
Simple enough...if you are consistently in an area with a WiFi signal, leave WiFi "always on"...it will consume less battery. If you're in an area without WiFi signal then turn it off, as searching for a signal will help run your battery down.

Again, simply not true unless you are using a 5-year old phone. Even if you are in an area that has no wifi connection, the extra drain caused by searching for Wi-Fi networks is minimum in a modern OS and modern chipset. I have left all my android phones (the ones that offer Wi-Fi always on feature for a few years now) wifi on all the time. Never have felt much difference vs if I turn wifi off. It annoys me that WP didn't offer this capability for so long.

I tested a lot of phones Android and WP, my experience is that wifi always on is a battery killer... And I'm talking about state of the art hardware... It's just my 2 cent's but i keep it off...
When I don't charge overnight and wifi is always on my battery drops about 40%
with only 3G on about 8-10%
Foxbat: you can leave it any way you want to do it. I'm not saying Microsoft should remove the feature. But in my experience keeping Wifi on kills the battery faster. I tested it for my use case with always on and with Auto and in the end: Auto it was for me.
The best advice you can give to people is: try it out yourself and you will see what works best for you.
A picture or two says it all. See the attached files for my two testing: one with wifi always on for 24-hour and one with Wi-Fi in auto mode for 24-hour:
The right picture shows 0.0%/hour under current discharge rate... pretty impressive

The keyword is 'Current' -- means at that moment. You can derive the same thing from the left in various sections. The key here is that I don't see any discernible difference. Certainly not a battery killer in any sense as you claimed.
If you look at the first 12-hour period of both chart (when the phone is mostly sleep and not used), the result is almost identical. FYI, there are three push emails connected all the time: Hotmail, GMail and Corporate Exchange Email.
Yes the keyword 'Current' -- means at that moment... so your phone is not discharging although your screen is on... Very accurate app...

So, what you saying is that if you have the screen on, you will see your battery percentage drop immediately? You should return your phone if that is the case.
Battery app get its information from the phone OS reporting. If the OS reported the same battery percentage over a short period of time, the discharge rate won't be anything other than zero. That's limitation of the platform, not app.
Instead of criticize the app which is not the point of the post, why don't you post your findings where leave Wi-Fi always on kills your battery?
it' % per hour... and your phone is using currently using 0,0% per hour so if you leave it like that it will run for ever... so where is the mistake?

% per hour is a unit of measurement. It doesn't mean you have to take one hour to measure it in order to claim its rate. That will be average rate on that hour, not current rate which is meant to see what your current usage pattern is. It can't be used to predict your battery life. If you notice that when you take your phone off the charger, it will stay on 100% for quite some time before it starts to drop. Does that mean your phone battery can last forever? Think about it before post these ridiculous statements.
Foxbat - you are trying to tell us how our devices should behave while we are telling you how they actually behave in the real world out there. You can repeat your 5 years story as often as you want to but it clearly doesn't live up to the factual reality we experience every day and I guess after trying it out with different ROMs on the 920 and leaving all other settings the same I know the effect it had pretty well.
Nice to know though that you are having a different experience with different devices.
Taking a close look at the long battery review thread, while there is a lot of information there regarding individual battery usage, the screen-on and overall usage times vary by a lot. It is impossible to draw conclusions regarding why the results vary so much, because most people did not give enough relevant information there.
I think it will be very interesting if we all used the same *comprehensive* method to compare our battery usage. We could really discover important things about our individual usage and how it compares to others (and how to make it even better).
It is important to note that when battery life is low (in comparison to other G2 users), sometimes this could be because we are taxing our device with heavy usage (and nothing is actually wrong), but other times something is definitely wrong (wakelocks, bad phone reception, etc.). This thread will help each and every one of us (that get lower than expected battery life) understand which of these two possibilities is correct for him (something wrong VS taxing usage).
In order to do this, let's use the excellent "GSam Battery Monitor" app, which could be downloaded freely from the Play Store.
Please post your results when your battery becomes low (around 10 percent), after it was fully charged.
If you want an accurate opinion about your battery behavior, with tips on how to improve things, please provide all the attached screens (please provide the graph image in landscape mode, and sort it by "other"):
Is this really necessary? The G2 has a fat battery. But any amount of power can be drained if you drain it. Enough said.

I say let's give this a shot. This phone has a beefy battery indeed, but still, some of us are posting 7 hours screen-on times, while some of us only 4. Let's see what this thread will provide us with. I have a good hunch this will be a very revealing thread.

Okay Well in the interest of troubleshooting good luck. I get 1.5 days easily with a good amount of music play. I always suggest people delete the Facebook app and use it in the browser, and disable data/sync while you're in a bad reception building/area

Yep, these are some solid good general advices.
I could only drain the battery to 50% today, so I'm posting this for now to get this thread running (and tomorrow I'll post the 10% results). It's funny because I have no trouble finishing the battery everyday, yet today it's giving me "problems". It's like it knows it is being monitored, and the battery hogs are afraid of being greenified...
Let's get over my results in the main screen:
Phone: yes, I did not use the phone to make phone calls. Not unusual for me...
Screen: almost 4 hours screen time, pretty impressive considering the phone has been running for more than 13 hours, and the battery is at 50%. On the other hand I did not make any phone calls, so this could be part of the reason for that excellent screen-on time. Btw, I'm using "Lux brightness control" instead of the LG2's pathetic brightness control feature, the Lux app itself drew practically zero power (as can be seen at the "App Sucker" screen, or actually, you can't even see it because it's too down in the list).
Phone Radio: At 7.9%, I don't really know whether it's good or bad, although this is definitely not a major battery user. I've attached the cellular reception screen too, just so people could reference with theirs. I think overall the reception is pretty good according to that image.
Wifi Active: The Wifi has been on the entire operating time. Most of the time it was connected to my home router, and some of the time it was not connected at all, but still on (when I was out of the house). I'm attaching the Wifi screen so people could see how much traffic the phone had through wifi, for reference. With only 3.9% battery usage, I think there is no need to turn the wifi off, ever.
Held Awake: The phone was awake for 1 hour (while the screen off, that is). Out of 13 hours being awake for 1 hour, I'm not sure whether this is good or bad. This will become clearer when more people will post their result here. It says that the power that was drawn during this 1 wake hour is 0.0%, I'm not sure if this is true, or some kind of inability of GSam to calculate battery usage for this awake period (if GSam IS correct, then I guess I don't understand what's the point of deep sleep, if the phone draws practically zero power even when awake...).
Bluetooth: The BT was on the entire operating time, but connected to a device only a short amount of time. In any case it drew no power according to this screen... like wifi, I think there is no need to turn the BT off, ever.
Regarding the "App Sucker" screen, I can't really say anything intelligent about this, no app seem to drain the battery too much. The 4 hours screen-on time was mainly spent browsing the internet, using Whatsapp, watching youtube, using XDA app (not even listed in the first screen) neither of which seem to drain the battery too much...
So, now that we have some reference (and a reference for a pretty good battery behavior, I think) It will be interesting to see how your results compare...
Just a quick question. I work in a building where there is terrible service. I mean so bad sometimes I get none at all. How does turning off mobile data save battery. Essentially your phone is still trying to connect to the mobile network all the same. I'm kind of looking for a technical explanation not just the 4g uses more battery type.

Don't forget, the vzw version will throw a wrench into these comparisons.

If you have bad cellular reception, turning off mobile data can help, but as you said it won't completely solve the problem because the phone still needs to connect to the network so you could talk and send SMS. I think switching to airplane mode (and using WIFI) is the best solution for battery life in this case. Still, I think you should use GSam to really see how much battery is drained by your bad cellular reception.
I am using it now. Waiting until it drops to around 20% to post my results. Will get back.
Edit:
Here are my statistics. You think my phone just has bad reception and is in a bad area or there is something wrong with my antenna? My old Droid Razr HD was the same way, barely any service. I'm definitely not staying with Verizon. I pay out the noodle for "the best service" and I get crap. I live on Long Island outside New York City, my service should be amazing.

Ok, as promised, here are my 10% results:
Phone: did have some phone calls today, though nothing significant. I guess my usage can't really tell how significant phone calls are going to be with the G2, though this should not be a significant battery drainer for most.
Screen: As you remember, yesterday, after 13 hour phone usage, I had 50% battery, I had 3 hours 47 minutes of screen-on time. At that point I thought I might get over 7 hours screen-on time, but here I show about 5 hours 25 minutes. I guess that if I completely drained it, I would have gotten close to 6 hours, not bad.
Phone radio: seems similar to yesterday, about 10% of the battery... I still get good reception, as the image shows.
Wifi active: Wifi had been on the entire time, using 5.6% of the battery.
Held awake: So, yesterday after 13 hours of usage, the screen was held awake 1 hours. Today, after a total of 31 hours, the phone was held awake a total of 3 hours. It seems that the phone consistently is held awake for about 1 hour, every 10 hours of operation time (under my specific configuration, that is). I still find it weird that this "held awake" time did not tax the battery at all. How is this possible ?
Bluetooth: was on the entire time, not connected most of the time. Zero impact on battery.
Regarding the App Sucker screen, similar to yesterday, can't say anything special about this. This day I kept browsing the interned using Opera browser, and added another hour using Runkeeper with GPS tracking (with screen off). After a full cycle of battery usage, the main battery draw comes from the Home launcher, next is Opera browser, and then the apps become pretty much insignificant in terms of battery usage. Maybe two last points here: I'm using both Lux brightness control (to control auto brightness) and Delayed Lock (to remove the lock when connected to certain wifi points and BT devices), both of these apps always run in the background, yet consume practically zero battery, so high recommendation for both of these (they also work great with the G2). Last point, I'm using all the google location access services (everything is turned on there), and I really don't see this taxing in any way, using this GSam report.
That's it for now. Waiting for your results for comparison.

Interesting results. I thought this thread would be revealing, and it doesn't disappoint already.
Your phone reception is pretty bad, much much worse than mine. BUT, you can see that the difference in battery draw is not really significant between my case (I have great reception) and yours, in both cases the phone radio took about 10% of the battery. It seems that the phone reception qaulity doesn't make much difference on the battery (whether it's pretty good, or pretty bad. Maybe this will change if the reception is horrific... like 0 and 1). Comparing my GSam report to yours, you will gain practically no battery advantage by making your phone reception better (at least considering your current phone usage - you barely made phone calls, but still phone reception is also important in order to keep the phone connected to the network, and also for mobile data...). This is REALLY surprising, I thought that when comparing my excellent reception to your very bad one, if I got 10% battery usage (for phone radio), you'll get something like 30%. This did not happen at all, surprisingly!.
Your Held awake time is pretty much similar to mine, as evertything else is similar to mine (wifi active, etc.), yet you seem to get significantly less screen-on time than I. I can think of one explantion: I see you are using G2's automatic brightness control, which is pretty horrible, while I use Lux brightness control, which can reduce the brightness much much more, when it's appropriate. I really can't think of any other major contributor to your battery drainage in comparison to mine...
One thing still keeps me bewildered: why doesn't the "held awake" period tax the battery ?? I mean, the phone is awake, yet no battery is being used... how could this be possible ? Is this a problem of GSam which can't read this information right ?

When you turn off mobile data the phone stops searching for a data connection, thus this battery draining process is halted

Barely read through the details but I charged my phone to 100% last night, pulled it around 6am today. Been texting and tweeting moderately. Made a few phone calls, checked voicemail. Used the flashlight a couple times and took a few pictures, flash off.

This is true but look at the sent part of data of the phone radio. My received data is much higher then yours but I can assure you I only receive data via WiFi because my phone signal is so bad. Your sent in comparison much more data then me probably via your phone signal.
This is also very important. I had my mobile data OFF while at work today. I have a shift tomorrow where I will keep the mobile data on and post new results.
Edit: Also about the phone being kept awake and not using any battery. It does seem odd. Perhaps we should also use the orginal screenshots of the stock battery app (pending you still have stock rom).

But, I don't see how the stock battery app will shed any new light on the kept awake period, if anything, the stock battery app is less detailed regarding almost everything...
I think we've ALL been here. Is there any uniform answer to this?
Let's be honest, I'm one of the not so frequent xda user, I always read several articles but have been, so far clueless.
I have the international model running on CM10 and constantly switch between ROMs of stock and CM, I've always liked AOSP ROMs, love the simple and uncluttered interface as opposed to the ever so bloated touchwiz. What else can I say? It has 32GB SD card and 16GB onboard storage, and it has a little trouble with 3rd party chargers (lose connection / disconnects every so often ) Its an old phone in technology time, but its still great.
So, I've tested wirh CM, stock and 2 other kernels which still make me feel like the phone is gobbling up a power plant everyday. One main culprit is Cell Standby which is very odd since it's usually just in my room (I use an other phone otg) and has a pretty decent signal (3-4bars)
On the most recent checks:
Cell Standby - 25%
Android OS- 18%
Screen - 15%
Google Services - 10%
Phone idle - 10%
Android System - 6%
And the rest are some of my apps..
I just recently started using Deep Sleep Battery Saver and wakelock detector. I'll send the info when the results are in for a day.
I'm not that fond of using 3G since data rates in my country are time-based and the KB-based pricing is off the charts. So I only use my phone for call and text and the occasional casual gaming and browsing (usually the cnet app)
I can only say that, if we could help on this either way, there are a ton of xda threads related to fast battery drain with varying issues because of Androids openness, I can only think if there would be some sort of centralized thread for this, or if you guys could help. That would be pretty awesome.
Ask any question or request anything so I could get this phone going. Thanks
Cell standby will be highest because you don't use your phone.
It's not a culprit,it is normal that it is up on the chart
But if you are experiencing any battery drain of more than 1-1.5% on standby then you have to look for an app or similar service running in background otherwise there is no problem
Press thanx if i helped you in anyway...
I don't think so. I left my phone's battery last night at 29% and after waking up 6-7 hours later, I got 16% left.
So that's around 13% consumed in one night without using it, or 2-3% drain per hour.
I already greenified Facebook and Lookout which were the biggest wakelocks, deep sleep gave me no noticeable difference even on Slumberer mode. I'm suspecting this is due to cell standby. the location which my phone was in had 3/4 bars of signal, wifi and location services are also turned off.
What's the big problem here really? I suspected it may be due to facebook but nothing has changed so far
Update: Signal strength is 73-80+ dBm, When I got home today the phone was dead from 16% this morning. The highest consumer is Cell Standby at 26%, Facebook is already turned off and everything, Still no perf difference.
So I also have a friend on and he's got a GS4, battery life was terrible for him since the kitkat update.
Anyone??
