Hi gang,
So, my area was upgraded to LTE recently and its good! But then, I also noticed higher standby power dissipation (which can be expected), but I wanted to know where I stood in the distribution. I charged the phone to 100% and went to sleep. When I woke up the following morning, it had lost ~20% of its charge, with about 8 hours of standby and minimal awake time.
So, can you help me by posting here, your details as follows?:
- Are you in 4G/3G area?
- % of battery lost overnight
- Time for which your phone was in Standby/Sleep for the night.
- The Radio version.
- The ROM you are using.
- Kernel version you are using and whether or not you are underclocking/undervolting. If you are then please specify the freq-voltage of the lowest slot (used in standby most of the time).
I'll start with mine:
- 4G
- 18 to 20%
- 8 hours
- MR2 leaked radio (1.39.00.0508w, 0.01.69.0510w_3)
- Gingeritis beta 9
- Imoseyon's v3.0.1test1. UC'ed and UV'ed: 184Mhz - 0.9V
I know that there are other factors that affect this, but dont want to make this complicated.
Thanks!

Disable the 184MHz, you are probably getting worse battery by having it enabled.
I've never lost a battery. I wake up in the morning and there it is. LOL
But seriously, I keep my phone plugged in at night, so when I get up, I'm at 100%.
I lose 15-20% overnight. dasBAMF 2.5. MR2 radio.Clocked down to 6xx MHz in screen off mode.
Overnight? When it's not being used and being unplugged serves no purpose? I lose 0% because I plug it up and let it charge.

Why do u take it off the charger at night? Makes no sense
OP wants to get a minimal rate of power drain and eliminate as many variables as possible. He wants to see how his setup compares to others. Letting your phone sit & doing nothing with it for 6-8 hrs is a simple way to figure this out.
I understand what you are saying, but really what is the purpose?
Yes it will give you baseline as to how long your battery may last, if you just let it sit.
But what is important is how long it will last when being used. That number can vary greatly depending on how you use the phone.
It's kinda like EPA estimates on cars. Does a car that says it gets 34 mpg really get 34 mpg based on the way you drive?
Thanks for the replies guys.. I just want to figure out how the power consumption in my phone compares to others.
@Benny
Yeah, i unplug the phone and dont let it charge overnight. Though the charging cuts off after its full, it can resume when it drops a little.

@dnakaman & abn75
Well, I meant overnight, just to get a period of ~8hours in standby. Since you have it plugged in overnight, just let me know the amt of charge you lose, when you keep the phone in standby without using for a long enough time.
@goos3y
I thought abt that too, but its not the 184Mhz.. coz I was getting good enough charge retention just before my area went to 4G. So this thread is to mainly compare 4G standby power dissipation actually.

Yeah, it differs a lot the way we use it. But when we are not using it (when the phone is in idle/standby) it should only depend on the phone's setup (the conditions i mentioned in the OP). Esp in 4G. I was just trying to make sense if the HTC thunderbolt in 4G coverage can lose 20% charge when its idle for 8 hrs.
I have never been in 4G until now.

Understood. I'm currently in a 3g area only, but I will be traveling to a 4g area next week (Viva Las Vegas). I know what my normal daily usage is roughly, I'll see if my battery is getting hit any harder since I'll be there a few days.
I just turn off mobile data and put the screen to dim. If someone really needs something, they'll call, and I don't need to know that someone liked my facebook status at 2AM.
On CM7 v0.4 I lose maybe 3-5% over an 8 hour night.

Now that the phone has been had a few days, what kind of battery life are you guys getting? Is it better than the Evo 4g at least?
A weeks time bro, but I'll comment. Out of 15 hours I am getting six hours of moderate to heavy use with 15% left... This phone's battery is looking promising.
Like I said though, we'll need a week before we all reach a consensus.

I used mine in a poor reception building for a 9 hour work shift, texting constantly and taking 3d photos for novelty of random stuff. I left with 55%. The key is using data only when you want to. I turned off auto sync and only used data sparingly, since I didn't need it on all the time.
Right now I got about 7 hours. Not happy but ill give it a few more charges.
Also I did not accept any ota so that's one problem.

14 hours off battery as of right now after a full (green light!!!) charge. sent about 120 texts, made a half dozen phone calls, and just below 60%. WiFi/Bluetooth on ALL day, and connected to WiFi all day. Even downloaded the OTA fix for HTC Watch.
The battery is AMAZING, and this is stock. The reviewers were full of ****. Although I believe the latest OTA fixed a sync issue, so that was probably causing unnecessary battery drain.
I repeat, the battery life is great.
if this is true... and im sure screenshots will b posted shortly, think of what this will be like on CM7 running custom kernels.........
Amazing battery life for me - better than 0G Evo, and far better than Epic 4G - though I did constantly charge that battery to oblivion. Looking promising!

A couple of things I've noticed right away.
1. CurrentWidget is inaccurate.
2. The upper limit on voltage during the charge scares me. On the EVO with an SBC kernel, we were always worried about going much about 4210 mV. On this EVO 3D, I noticed a 4275 right away. Seems to me that at 4300, it's all over, right?
3. I did not notice the precipitous drop from 100-90 or so that occured after taking the EVO 4G off the charger.
2 hours 27 minutes from full charge to "connect your charger" with everything turned on and video playing. About five minutes after plugging in video playback stopped and another message popped up stating that charging rate wasn't sufficient for current power usage. I wasn't using the included charger though.
Battery meter is flaky though. Reading 99% most of the time while charging and green light indicating full charge didn't come on 'til several minutes after battery status read full.

It's a bigger battery first of all...not that much bigger, but, I don't see that voltage completely out of line...and it is OEM after all...typically nobody plays it safer than OEM...
14 hours 39 Minutes of the charger. Battery is still at 34%.
I was on and off of WiFi and used the phone more than i normally would because it is new. I checked facebook a bunch, texted as I normally do, surfed the web a bit, checked email, twitter, took several 3D pictures and a couple of videos, used a few apps....blah blah blah.
I am very pleased with the Battery life so far.

So todays my 1st day at work with my evo3d. With my 4g id take it off my car charger at 6am with a full charge then by about 10am id have to stop using it to text or browse bc the battery was in yellow. So today im looked at the battery indicator at 7am....8am....9am lol and nothin changed. So i checked the battery in the settings and it actually dropped to 95%. Just to be sure i reset the phone and it was still at 95%. Wow im so amazed at how much better this battery is vs the 4g!

I look at my remaining battery when I go to bed and think, boy, could have used this thing much more.
The only problem is that I don't know that it will make it 2 solid days without a charge session. I'll have to see if that's possible on light use/strong signal days.
Mine so far, 4 hours with moderate to heavy usage and I have over half my battery left. Pretty good so far, much better than my OG EVO.
on the days that I think, "wow this thing has incredible battery life--it's barely moved at all since I unplugged it!" typically it will just plummet to like 50% without warning... the battery indicator is pretty much a joke if you ask me.
well...as soon as seido releases their extended slim battery i think it will be perfect...i have no complaints about the battery now and I was getting about 40 hrs on my OG EVO after putting cyanogen on it

+1 for the extended slim, can't wait to see that
It's funny, but I'm not quite jonesing to root my 3VO quite yet. This has got a lot of new technology (3D, asynch dual cores, 4G, etc.) that I want things fully baked. I know 4G's not exactly new, but considering how many ROMs for the OG EVO had issues getting it up an running (not to mention lost WiMax keys), I still consider it an extra challenge.
I had the 2000mAh GaliliO battery for the EVO 4G, and would go morning 7am to late evening without issues, 14+hrs with moderate use.
I would say the 3vo is comparable, but on a 1730mAh battery, It's scraping up to around 10hrs of moderate use, and I have not spare to swap out yet. Out of the box, the battery beats EVO out of the box last year, but still leaves something to be desired.
I've got a couple 1850mAh's on the way, hoping they don't blow chunks.

How much charge? Many have noticed the battery cycling between 95-100% once it's fully charged. If you're losing more than that, you might want to look into it a bit further.

Funny, my Evo 4G would have been around 85% after that... unless I was in a fringe area, then all bets are off. I never ran Sense ROMs though, so it might not be a fair comparison.

It stays on Wifi whenever I am at home then I switch to 3G when I leave. Brightness is set to Auto. I never turn on GPS, (that's what my Garmin's for) and everything sync's normally. It's weird, some days I'll get this kind of battery life and somedays I'll get a lot less. Even with similar usage from day to day.
I get about two days of use with everything on. (No gps or bluetooth) Facebook sync on, texting, web browsing xda app, and a couple short games. I don't ever have any battery left though..
If I stay home I have closed to 60% left after 18-20 hours of regular usage----a few calls, browsing, games and texts----but I have wifi and an airave

Simple. Take a screen shot of screen on time. Who cares how long your battery lasts, if you don't have alot of screen on time.
I read this trick from somewhere (possibly a myth?)
Charge phone to 100%
Unplug, allow 5% discharge,
Charge back to 100%

I'm not completely sure about this, but here is what I remember reading:
That was only useful on other phones when it would display 100% when really the battery was 90%. Doing this charged it to the maximum battery capacity. The Evo 3D stops at 100% when the battery is actually full so we don't need to do anything.
I think this phone does not register being plugged into the computer as being "plugged in." Therefore it does not reset the meter, and you get readings like this, even though there was some (computer-connected) charging in between.
I want to test a theory guys. Anyone else who feels they want to be a part of this feel free.
This is what I want to do. I want to test the actual draw of the screen in a normal days use over 2 days. The first day set to ~25%, the second day set to 75%. What I want to see is how many minutes at those brightness the screen was on. And the difference in the usage on the battery on those 2 days.
You don't have to be dead on with your estimation of time the screen was on, but try to be within a few minutes. If there isn't much of a difference then I believe the screen actually is pulling power while "off" and killing our battery unnecessarily fast.
There is no reason on 12 hours of battery, with screen on less than 30 minutes total that it should consume 65% of the battery! I don't actually see my battery drain 65% right before my eyes while it is on, so something has to be happening behind the scenes.
Edit 1: Post a screenshot of your results from both days. Tell me what connection type you used through the day. What ~% your screen was set to on both days. I only need the screen percentage changed, as long as everything else is consistent it is irrelevant to this test.
Day 1 do a low 20-30% brightness, day 2 do a high 65-75% brightness.
Edit 2: I just realized that when under battery use you can click the specific process (here being Display of course) and it will give you the exact amount of time used by the screen. If you guys could, please post both screenshots, as well as give me the accurate amount of time the display used battery.

I don't know if you ever had the original Dinc (I see an Inc 2 in your sig) but on stock ROM that phone constantly reported 60%+ Display usage no matter what you were doing, even lightly used. I crank my brightness down to like 20% permanently. I don't use it outside, so I don't need it super bright. Did it on the Dinc, and I'm doing it with the Rezound. Usually see display around 30-40% unless I'm using it heavily.
And it's not consuming 65% of the entire battery, that is 65% of the total drain is attributed to the display. SO if your battery has gone from 100 to 90% in 30 minutes, and 65% of that is display, your display has drained 6.5% of the total battery.
This is why I said over a day dude. I didn't say tell me what it says right now. If you don't want to be involved in the experiment don't bother posting in this thread. That goes for everyone. I stated 65% of the total consumption. If you really think I am an idiot don't waste mine or your time posting because you will just piss me off and I will report your posts.
If you had read the post correctly you would understand that I get 12 hours or less of battery life while only using the screen for maybe 30 minutes out of that 12 hours. Yet it reports 65% of the consumption is due to the screen even on 20% brightness. Theoretically that means I should be able to use my phone screen for 30 minutes straight and should be able to watch my battery drain 65% in that 30 minutes, which it does not. Therefor there is something else pulling power either stating it is the screen, or the screen is drawing power when off.
Hostility unwarranted. I misread your post, simple explanation.
I'll try cranking my brightness up and see what I get over a day of moderate use, how about that to make up for it?
Lol, Sorry man, I haven't seen you post here before. There are so many members who just post to post. Everyone has their 2 cents, you know what I mean
Appreciate it though!
I'm willing to try this. I'd have to start tomorrow. I also have a few basic questions.
1. How are you estimating time screen is on? Is there a way to do it other than just me paying attention? Cuz that's hard for me.
2. Does that stats page need to be reset at the beginning of each day? Also, where the hell is that thing? I've been to every setting on this phone exploring it and then when I want to find something again I can't!
3. Does it matter what power mode the phone is in?
And I was thinking to add to the test it might be interesting to see what having the screen on "automatic" would do.
1. I don't know of a surefire way, if someone else knows let us know! Otherwise, just a rough estimate is fine 30 mins ~35 minutes really. As long as you don't overshoot too much.
2. You don't need to reset the stats, they do it automatically after being on the charger for an extended period. So if you charge overnight and take it off it will only show from when the phone was disconnected. Settings >About Phone > Battery >Battery Use.
3. Power mode should have no relevance. But I am using "normal".
You're going to have to specify if WiFi or 4g/3g is to be used. I have noticed over the past few days that 4G consumes roughly 1.5-2%/hour less battery than WiFi does. On my Dinc, WiFi would draw a lot less power over time than 3G, but not so with the Rezound. So now I leave it on 4G while it sits idle at work unless I need to download something big, in which case I'll switch to WiFi, even though I have unlimited data and technically don't need to care lol. But I found that with WiFi and 4G both on and WiFi connected, my phone was burning like 5.5% per hour of battery. With 4G on only, I'm going through ~2.5% per hour (these are both with the phone sitting idle, usually in the morning when I'm busy at work). That's pretty much what my Dinc was doing on Wifi. I'll have to try it sometime with WiFi only on, and 4G off to see what happens.
But regardless, please specificy WiFi or 4G. Any testers that volunteer for this will need to leave that connection on as their sole connection during the duration of the test, save for a few mins of variance here and there.
Doesn't seem that should affect how much power the screen itself uses though. He just wants to test screen battery usage, not overall battery usage.
EDIT: Oh, if we are talking percentages then yes, it would matter. I generally leave my phone on 4g unless it decides to turn it off. And I switched to wifi a bit ago since I was required to to download an app from Amazon.

You're going to have to specify if WiFi or 4g/3g is to be used. I have noticed over the past few days that 4G consumes roughly 1.5-2%/hour less battery than WiFi does. On my Dinc, WiFi would draw a lot less power over time than 3G, but not so with the Rezound. So now I leave it on 4G while it sits idle at work unless I need to download something big, in which case I'll switch to WiFi, even though I have unlimited data and technically don't need to care lol.

You are describing exactly the opposite of my experience with 4G vs WiFi battery consumption.
Hmm, interesting. Maybe I just have really good 4G signal? I too thought it was weird, given my experience with the Dinc being exactly the opposite of the Rezound. Trust me, I'd love to know why it happens that way too lol. But again, I shouldn't care because I have unlimited data, and the 4G is faster than the WiFi here at work and about as fast as my home connection (I average on the lower end of the 4G scale, about 10-15Mbps), so I'll probably just leave it on 4G for now unless I'm at home and need to FTP to my laptop or something.
And feralicious, I agree to an extent, but to get truly accurate results we at least need to know what X person was using for data over Y person, since both connections will draw power at a different rate. The only other accurate way to do it would be to keep the phone in airplane mode. And since he's using approximately 5% per hour of battery, whereas I'm using 2-3%, maybe he's on Wifi where I'm on 4G. As in any testing you need to have a control along with the variables, and the data connection is a big variable that could easily be made a control. Just my $.02

Yeah, I just realized that and edited my post, didn't see you had responded.
For the record, 4g seems to pull more power than wifi for me as well.
Just post a screenshot of your results, tell me the amount of time your screen was on, and what your primary connection was. This is the only info I need. Your connection will only minutely affect the percentage that the screen draws. I only want to know the difference between screen high and screen low. So long as everything else is consistent on your end your results should be accurate for what I need.
Looks like I have to extend it out a day. I set my phone to 75% brightness and go figure it is the day that the network is having outages. My battery lasted ~2 hours today doing nothing.
Wow. 2 hours?!?! Will start the official test tomorrow as well but for the record my screen was also at 75% and I got almost 10hrs and I texted, shopped for and played with apps and watched a few app videos. I turned on wifi for a few hours due to network outtage.
Posting results even though they're not considered official. My screen was on approximately 1-1.5hrs in my estimation.

lol I woulda been in the same boat, if I didn't have a coworker alert me that 4G was out. I hadn't looked at my phone all morning, and woulda had a dead phone from it constantly looking for a 4g signal.

I had no idea, my phone was in my pocket and I was busy all day. Never felt it ever get warm, pulled it out of my pocket when I had some down time to check my G+/FB/Twitter and BAM.. phone wouldn't turn on. Luckily a friend had a charger and let me hook up. Turned on the phone to see the battery had actually died. I took it off the charger at 11:30 and it was dead before 2.

Thanks, I will be trying high brightness again tomorrow.
I couldn't get a reliable test because I had a stupid setting left over from my experiment with Economy mode that turned WiFi off after 15 minutes, so my data is skewed a bit from the first day to the second. (Plus the roving 4G outages caught me last night and my battery went from full to 5% overnight.)
Also, I use an app called SystemPanel (bought the Pro version) which gives me nice plots of my usage and screen on time, if you're interested in more data like that, you could look into it.
I just realized last night if you click the process in the battery use window that it will show the time that process uses power. Soooo.... I need everyone to start from scratch and give me the accurate amount of time the screen shot is on, for both dim and bright settings. Sorry guys! OP updated.
Long story short, I bought the HTC EVO 4G LTE (The US carrier, Sprint's variant on the HTC One X). Sprint has a 14 day return policy. For me, it ends on Saturday. I'm considering the GSIII.
But the most important thing is, how's the battery life? How well does it do when you're using 3G?
But most importantly, how badly does heavy texting (as in, new text messages every minute for about 4 hours) effect the battery?
I text all day long from 8am to 8pm (medical school ) and WhatsApp/xda app. Lasts the whole day. But I run in edgge not 3g

I'm in the same boat as you. I love the screen on the Evo but the battery life and multitasking issues have got me strongly considering the GS3.
I've been haunting the forums here and it seems like people are getting amazing battery life. There are many people posting screenshots of 5-6 hours screen on time. I've even seen some that exceed that. By contrast my Evo has been running 3.5-4 hours. That's less than what I was getting on my OG Evo (of course it was rooted and running a custom ROM/kernel ).
I just went and spoke with my Sprint representative about what I'd need to do to make the exchange. I'm 95% sure I'm going to pull the trigger on this switcharoo.
Best of luck in your decision!
Was quite bad at first, but something changed.. now it's awesome. 15 hours and 70% left. Moderate usage and 3G/HSPA+
Do you know what changed to your phone?? 15 hours with 70% left is amazing How often were you using the phone ?
The battery life is fantastic. Just turn off the crappy S-Voice features that wait for your voice input.
How long is the screen-on time? I seriously doubt texting requires heavy usage of the radio. So, the screen is obviously going to be the biggest drain on the battery.
Battery life is misleading straight out of the box. The starting charge is completely out of sync with the phone.
I had to run my battery dry and full charge it to calibrate the battery properly. Once I did, then battery% values balanced out and phone has been a dream ever since.

it was with moderate usage (lots of texts, a few calls, a bit of game play, but not much) and I turned on power saving when I wasn't using the phone(don't know whether this actually does anything when the phone is asleep anyway... and off when I was). Don't have s-voice running (disabled it manage applications menu), turned off motion as I never used it, turned off NFC, S-Beam and Wifi-Direct (some of which were turned on by default! and this is SUCH a battery killer)...
Basically turned off everything that I don't use.. and saved a hell of a lot of juice.

I think the longest I got was almost 30 hours, thats using whatsapp, heywire, facebook and skype here and there and tinkering around in the marketplace. I had most of the settings switched off as you did...just noticed I had nfc on...switched that off too now. I just joined the android community, switched over from my Iphone this week when I got the SG3 so im still getting used to it
I think because of the quad procesor the 2.100mah wasent enough.It is very good!All day from the morning with 100% with full brightness,wifi,download gameloft games,gps, and i had 20% the next morning!!With custom roms will improved more!!

24 hours gets me to about 20%. That's with WiFi on all the time. Pretty good yea?
Almost 24 hours with heavy usage, on my previous S II it took two charges or extra battery for same (smsing, surfing, calling, half of time on wifi etc...) always on 3g
There's a whole thread on battery life here: http://forum.xda-developers.com/showthread.php?t=1681873
Probably didn't need to start a new one..

I will agree with the above statements. I use the 2x battery app and I have moderate daily use which gets me at the end of the day around 10:30 from 8am to around 45-48%. That is with 3g when the screen is unlocked a bit of wifi, web browsing and tapatalk, a phone call or 2 etc. I have disabled all apps i don't use as well and run the stock kernel and no roots

I managed to get the 99% battery issue sorted!
I have used he external battery charger on my 2nd battery and today I thought of trying the new battery for the first time to get some cycles on. Guess what?
The samsung desktop charger powers the battery all the way. I have now 100% on the new one and it dropped as I'm typing now after a good 5minutes of operation, unlike it used to do which was immediatelly after unplugging the charger from the phone.
So I presume that goes with the original assumption that the phone does not overcharge the battery for lifespan purposes. Why would the desktop charger would though?

I'm now giving this method a try.
Charging up my spare battery with the Samsung desk stand/charger.
---------- Post added at 09:48 AM ---------- Previous post was at 08:56 AM ----------
Interesting.
I've found the same as above with the 99% issue.
Having charged my spare battery up in the phone, I've then put it in the external charger, which after another 10-15 minutes charge, the LED turned from red to green.
Having now put that battery back into the phone, the battery is still on 100% after being unplugged for more than 30 mins.
Usually, the battery would have dropped to either 99% or 98% as soon as it was unplugged.
So, it would seem that the desktop charger does charge the battery up to the full capacity, while the phone itself, seems to stop at 97-98%. Weird.
