I've done a little experimenting, made a spreadsheet and all, to see what makes a difference to the battery drainage. Here are my findings -
Live Wallpaper: YES
Connection: 3G
Taskiller Widget: YES
Battery Drain: 7.5% per hour
Live Wallpaper: YES
Connection: 3G
Taskiller Widget: NO
Battery Drain: 4.5% per hour
Live Wallpaper: NO
Connection: 3G
Taskiller Widget: NO
Battery Drain: 4.4% per hour
Live Wallpaper: YES
Connection: 2G
Taskiller Widget: NO
Battery Drain: 4.15% per hour
On average, using one of the 4.XX% scenarios, if it was left asleep for the hour it drained battery 2-3% per hour.
Heavily used for the hour, browsing the web on lunch drained battery 6-9% per hour.
Mind you, today has been relatively light use all day, Live WP, 3G and I've got 3.7% all day. At this rate, I would probably get 27 hours use. The battery does seem to get better after a weeks use, so don't judge it straight out of the box. I know some people said using 2G would save battery, I was surprised how little it did.
One thing I used to do on my Hero to save battery was turn of auto rotate. Tomorrow I might try that and see how it helps battery life.
Are there any other things you'd like me to test?
I don't believe so, no. I might try again next week with them off, just to check it wasn't the battery getting better that scewed results, but so far, they look to make no difference
It seemed that the live wp drained my battery more when I used it, even when it wasn't on much. I may do another test to see.
I find that the battery lasts a little longer if you power the phone off before charging it. Today I've been streaming Last.fm, played about 20 minutes of Julelust in the bathroom and did quite a bit of GTalk chatting, and my battery is at 85% after about 3 and a half hours.
I wonder if it depends which LWP you use? I was using the Live Earth Wallpaper...
Also, I might try underclocking to 600mhz for a day, to see what that saves.
For me, I'll probably use it with all the bells and whistles on, even if I only get 20 hours life, as long as I know I'll be home to charge it that night. If I know I'm out for a couple of days, I'd like to know what settings I can change to extend it up to maybe 40 hours hopefully.
I should also do a day where I turn of data sync, I think that makes a big difference. If you turn it off with the power widget, will it stop everything using data? E-mail, apps, everything? Or do I need to actually turn data off for that?
Very interesting. Which task killer widget did you test? Thanks.
I think it was the one from ES Task Manager. Now I've got Advance Task Manager and just place a link to the app rather than the widget. It's still only 2 presses to kill everything.
I have the paid version of TasKiller, which I used for a long time on my Hero, I should test that at somepoint too...
nice topic.
Can you tell which Rom are you using?
Default?
Cyanogenmod?
Modaco?
I don't think this is relevant unless he's running a stock ROM with no 3rd party apps installed. Also, if you believe the battery gets better after a week of use then why perform any tests until after that week has passed???
This testing is flawed in another way; inconsistent usage patterns.

It surely is.
It changes many thing including if it's needed to kill an app to boost memory etc.

So leave the thread and don't be so negative.
Yes, Modaco's 1.5, some in Cyanogens. Why would an app in one ROM use more battery than it does in another? This testing was for me, why would I test in any ROM other than the one I use? I just thought others might benefit from what I found.
Why should no 3rd party apps be installed?!?! Some of these are what I want to test!
I did wait a week...
Of course there are inconsistent usage patterns. Even if you tried I bet you couldn't do exactly the same things every day at the same time with your phone.
This is not a scientific experiment, it's just my findings. I'm not claiming I can tell you how long your battery will last, as I said, I just wanted to know what things helped and what things hindered. Please have the good manners to not bothering to return. Thanks.
Hey guys,
Just got my Epic yesterday.. coming from the G1 with lots of experience loading and tweaking ROMs and dealing with same/similar battery issues.
After unpacking the Epic I used it and let it drain down to zero before recharging it; after a full recharge, I loaded up the 7 screens with widgets and ran a live wallpaper (fish). I didn't really use the phone much at all and the phone went from 100% battery down to zero in the span of only four hours!!! Geeze, you've got to be kidding me - four hours battery life?? WTF????!!
Back to the drawing board: I rooted it and ran SetCPU with some power saving profiles. Removed the live wallpaper and went to stock wallpaper. Set display power off at 30 seconds. Note that 4G remains off since there's no 4G in my area..
Couple of questions:
1. Is there any way to toggle 2G/3G like there was on my old G1? I know that was a power saver.
2. I didn't stop to read all the documentation yet (typical male, I know) but is there any way to wake this thing up from sleep mode besides pressing the power button? I can see that power button breaking for as much use as it's getting from me constantly having to wake this thing up!
3. My brightness setting is set to auto - since the display is usually the biggest drain on these things, is there a recommended manual brightness setting (percentage) that seems to work well for you and saves on battery power?
I'm waiting for the Seideo Extended Battery (just like many of you) and am wondering if I should keep the Epic since I'm on the Sprint 30-day Easy Return program.
Appreciate hearing from everyone!

I don't have 4G where I am. But, I have a all black wallpaper(uses less power) and unrooted. I easily get about 12-18hr out of my phone wit normal use(text, talk, and surfing the net with skyfire). Only thing that really kills my battery are games(Robo Defense can take over 30min to play one game).
Thanks for the reply - situation NOT improving
Thanks for the reply.. unfortunately, the situation is not improving...
I tried setting a Sleep Profile using SetCPU that would under-clock the CPU (using the stock kernel) once the screen dimmed and the phone went into Sleep Mode. Unfortunately, as mentioned in another thread here, the result was that the phone froze and required a battery-pull to reset.
I'm really starting to lose my enthusiasm for this device; as beautiful a display and as responsive a CPU/GPU, all of that doesn't mean much if you don't have good power management built into the firmware. At 6PM this evening I pulled it off the charger at 67% charged, it's now 8:35 PM, only 2.5 hours later and I'm down to 22%. I'm in a decent coverage area and get 2-4 bars of 3G strength so I don't think it's an issue of the radio being the culprit; in-fact if you check the battery stats it reports that that lovely Display is accountable for 78% of the battery usage! So I guess we're paying a hefty price for these 4-inch AMOLED displays!
I read somewhere else that the most recent update (DI07) has caused the battery performance to decrease; since my unit is brand-new it immediately went and installed DI07 shortly after the first boot-up so I have nothing to compare it to.. can anyone comment on that?
Thanks!
Chris R.
I'm sure custom ROMs will put performance / battery life on the top of the list but until then, I use JuiceDefender beta and have seen pretty good results with it. It shuts off data whenever the screen is off and since my screen is off a good amount (only use my phone if I need to check email, call, and / or text, which is rare when I'm at work). Other than that, yes, use black wallpaper, lower brightness to the min. in the OS and browser, and don't leave apps that constantly use 3G open (things like ebuddy, pandora, etc.). 3G really destroys battery life so minimal use of 3G data would maximize battery life. Maybe the devs can figure out a way to get at least one full day of battery life on this phone. I'm hoping that is the case.
As to your post, yes, DI07 has resulted in poorer battery life, for whatever reason. I was definitely getting a few hours more with the older firmware. I would not lose hope yet. As disappointed as you are (and all of us are, I can assure you of that), the devs are really starting to push out nice ROMs already, and in a few weeks to a month, I bet we will see some solid battery life. Hell, even 2.2 should yield much better results. Patience
Thanks for the tip!

DI07 has hurt my battery life substantially. In fact, my battery drains very close to twice as fast now with the update. I don't understand what they did. My phone certainly doesn't seem any faster, my display is dimmer, and battery life sucks. I'm going to have to go back to DG27 so I can use my phone all day. With DI07 it always dies on me by mid afternoon. With DG27 it was still running by 11pm at night without even a battery low warning.
juice defender ftw
also, use advanced task killer with low security settings to kill all the background processes. Set the autokill to when the screen turns off. This keeps everything pretty well managed and helps with battery as well
JUICE DEFENDER BATTERY!!! Saved my phone from flying out of my car window at 10 in the morning........
here is a link to a thread I started.
Sharing my juice defender settings. I also use ultimate juice.
http://forum.ppcgeeks.com/sprint-epic-4g/133933-sharing-my-juice-defender-settings.html
I can get a day and a half (or slightly longer) out of a single charge.
YMMV.
Hope this helps
Advanced task killer + Juice Defender. You could also get some custom roms and Kernals that would help boost it.
But that's your best hope. Keep off 4g, wifi, bluetooth, etc.

Look here- try stopping the DRM service and see if that helps your battery life with D107

Ah, the evils of DRM can strike in unexpected ways...
I wasn't really having a battery problem but I just turned DRM off, so we'll see if battery life improves anyway.
I had a whole long post here that got wiped with the xda disk array failure, so I'll just sum that up here too:
1) Use wi-fi if possible - it REALLY helps
2) 4G does not seem to use the battery any more than 3G, although hunting for 4G does and 4G coverage is not as extensive as 3G even in 4G areas. So it's still best to leave it off if you're moving around.
3) Dim your screen and use a dark, static background. AMOLED screens don't work like LCD's; they use more power the more pixels are lit and the brighter they are.
4) GPS also kills your battery - leave that off unless you need it too.
I think that's it. I get about 18 hours on DI07 (even before trying the DRM thing; maybe I can get to a full day!).
One thing I'm noticing after checking DRM - I've got Google Maps' LocationService popping up about every 10 seconds, and I can't seem to shut it off permanently. (I went into Lattitude and turned that off, not sure what else to do.) That can't be helping... anyone know how to get rid of that?
I'm using juice defender and a constant email junkie, but lite use on other aspects of the phone. It goes off charger at 5:30 am and I'm about 67% at around 3p. It then goes in the car charger on the way home. This has much better battery life than the Pre or the Hero as with both I had to turn off email to get it to last throughout the day.
I don't expect these phones to last days, but I expect any phone that I get to last the business day. I've always been one to charge overnight.
Wifi drains battery more from what I've read.

I've heard the opposite that wifi (as long as it's connected) uses up less battery than 3g/4g. Any of them will suck the battery dry if they're searching, so make sure you have a connection to one of them.
Hi everyone, new to the forum. Just started checking it out when the Epic was released and this is my first post. Anyways, here's my question. My phone's been off the charger for 7 hours and 17 minutes and it is now down to 15%.
Display 79%
Cell standby 7%
Android System 4%
Phone idle 2%
Swype 2%
I've gone into the display settings and I thought I had set everything up optimally. The brightness is always very low. The screen timeout is 15 seconds and the keyboard matches that. I don't know what else I can do to cripple the phone to get the battery to last longer.
I have had wifi on, 4g off, bluetooth off, gps off. Really all I have done this afternoon while watching NFL games is check my yahoo fantasy score, play 2 games of WordFeud, and check twitter and facebook. I purchased Juice Defender a week ago and it has been running all day.
Any suggestions for how I can reduce the drain from the display? My background is a black and white picture of a friend of mine, which I thought would help.
Don't get me wrong, I love this phone. But the battery life I've seen is just terrible. I'd love to buy the extended battery from Seidio whenever its available, at least that would make it last longer even if the settings aren't tweaked.
Do you have juice defender installed?
Yep. Its installed and running now.

There are only two reasons for your display to be using that much battery:
a) it's too bright, or
b) you're using it a lot.
If you're using the phone a lot, your battery's going to run out pretty quick and there's no way around that. If you're using it a "normal" amount, which to me means maybe an hour *total* per day of having the display on, then the other culprit is going to be your brightness. (Some would argue that's less than a normal amount, but think about it... you get a new phone, you're going to play with it for a week or two until you've seen all the cool stuff. But at some point you're going to start putting it away most of the time and just using it when someone calls you, you get a message/email or maybe to play a game or two while waiting for the train.)
Set your brightness *all* the way down, just as a test for a couple days. Make sure all the "power saving" features of the display are turned *off* (auto brightness, and whatever that "picture detection" feature's called, I can't remember). You just want the display as dim as possible all the time, just to see what happens. See what the battery usage says after a day or two of this.
My bet is that you'll see a drop, and then as you get into a more normal usage pattern it'll drop further still. You can raise the brightness a couple ticks then as you learn how to stretch your battery out.
Personally, my display is rarely over 15% or so of my usage. Today it's 29%, but it's a Sunday and I don't have anything better to do but play around on my phone.
btw, it's still the first day I've tried this but that DRM thing might be working. It's almost 9PM and I'm still on like 80% battery, and like I said I have been using the phone off and on throughout the day.
That has helped tremendously. I installed it pretty much when I got the phone and I'm able to last the whole work day with 67% left. (10 hour day)
Anyone having battery problems? My wife and I have pros and can hardley get half a day out of it... does this phone need a task killer? I havent used a task killer since my hero. But maybe this one needs one. any ideas? my fascinate holds a charge more than this and it does 10 times the amount in the backround and the batterys arent that different. Thanks
Pretty disappointed with the battery life too. Barely make it to the afternoon. I just constantly plug the phone in. Considering buying the extended batt if it wasn't 50 bucks.
I also switched from the fascinate.

who has the extendted battery
My battery life is OK, but I'm constantly fiddling with the phone: checking facebook, answering work emails, browsing the web and the Market, etc.
However, my partner's phone made it through a 16-hour day with 40% still left of battery. Granted, it was on standby for 6 hours at work, but the rest of the time was constant facebook, etc.
There are a number of "Power Management" tweaks that can be performed that will dramatically improve battery life. Things i have done include:
device rooted via z4root (this has no direct impact on battery performance but necessary for things that do...)
Screebl Pro
SetCPU (throttle down to 300 when screen off)
AutoKiller Memory Optimizer
Uninstalled or frozen a bunch of stuff i don't use via Titanium Backup (there is thread in this forum that discusses what can be uninstalled/frozen)
Changed phone radio from global to cdma
I have also added an extended battery. I can easily go 12+ hours with heavy data/email and voice use.

these are all great ideas. however, most of the reviews are bad on the Screebl Pro and all of its other versions.
I just received mine yesterday. Gave it a full charge last night. Now, at not even 11am, it's down to 60%. That's after three hours of light usage. Hopefully this is just a battery calibration issue or something since this is the first time it's been fully charged...
Edit: 10%. That's 90% depletion in just five and a half hours. We'll see if it's lying or not.
Edit: The Droid Pro was pronounced dead at 1:48pm, exactly 6 hours of very light usage after its first full charge. We'll see what happens on its second cycle.
Hi All
I have to say my battery is great. Can make it the entire day even with heavy usage.
However, you need to be really careful with the background apps you are running.
In my case
1) Bluetooth off
2) Wireless Off
3) Set CPU running - scaled to 300 when screen off and scaled to 300-600 when battery hits 50%
4) Running IMO messenger at boot (I tried Ebuddy and it sucked down the battery big time) IMO does not.
5) Cleared most of the default widgets and only added the few that I really use.
6) Running Go Launcher instead of default launcher (not sure if this helps battery or not)
7) Running CDMA mode only when I am in the U.S. (turned off global setting)
8) I get LOTS of emails daily (over 150) so the phone is constantly pulling in.
Hope this emails helps others.
When I first got my Pro a few weeks ago I was ready to send it back due to poor battery life. Decided to give it a little more time, and the stock battery was netting me at least 12 hours of moderate to heavy usage. Ordered the extended battery and had the same issue of it draining the battery insanely fast. Again, I gave it a few more days and now I'm finding myself charging the phone maybe once every two days. All in all, just give it some time -- it'll surely get better, just hang in there!
Day two: Seven hours in, and my phone is down to 20%. Better than yesterday (dead in 6 hours), but then again I used it much less today, and I removed all but 1 widget from my desktop.
Edit: Dead at 4:20. 7.5hrs today. This is garbage.

Try and hold out for a week. My Dream and Milestone took about a week before they were useful. If its not useful after that then you might have to trade it in or get a different type of phone.
Android is not known for its great battery management but you should be able to make at least a typical 8 hour work day imo.
I've stated in many threads in many forums now, the battery life with the "Out of the box" setup is just horrible. No way around it, it just sucks. The stock battery is the same one that came with the original Droid last year. The Droid 1 is a 600 Mhz stock phone. Our Pro is a 1 GHz beast. The stock battery in our phone is just inadequate.
I wouldn't be surprised to see an update in the near future to resolve some of the issues we are seeing though. It's obviously the biggest complaint with the phone. However if you are willing to root you can get the phone to somewhat reasonable battery life.
I've really only done a few things but am seeing a vast improvement. Stock settings with my usage gives me about 4 hours then I'm dead in the water. Now I get about 7 hours and I'm literally doing something on my phone all the time so I'm completely pleased with that.
My main things:
Root and remove the bloat. Play with the phone a couple of days, find out what apps you'll never use then get rid of them.
Get a different launcher, either Launder Pro or ADW.
Buy SetCPU and set profiles for:
Screen off = 300 MHz
Battery < 70% = 800 MHz
Battery < 50% = 600 MHZ
Change wireless mode from Global
That's it for me. If I used my phone like a normal productive Human I could get a full day easy, but again its literally always in my hands, so 7 hours I am very pleased with. That's about as long as my old Curve got me. After that I just slap my spare battery I always have in my back pocket in and I'm good to go with only 2 minutes downtime, as opposed to the 15 minutes down with any Blackberry battery swap.
That's my 2 cents, take it for what its worth. My biggest battery gains came from SetCPU, and to be honest I really can't tell a difference in performance when it throttles me down.

Which extended battery? Do you need a new battery cover?
This guy is selling his Droid Pro for $500 with extended battery.
http://cgi.ebay.com/Motorola-DROID-...0741502439?pt=Cell_Phones&hash=item3a615bb1e7
The battery life on this device is very low. I ordered my extended battery here on eBay: http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=150532539861
I like that is has an original backing and there is no noticeable bulge.
Verizon is selling extended battery for $50+tax with free overnight shipping.
I got lucky. The seller has since revised his listing to NOT ship outside the united states. Its a shame for all those who've purchased their phone for use outside of the usa.
Well I have to contradict my last post. I burned through 2 1/2 standard batteries Sunday during a 16 hour day at work. I decided to break down and purchase the extended battery.
I bought it yesterday and threw it in my phone last night before I put it on the charger for the evening. Today I'm very surprised to see I'm still sitting at 40% with the phone being off the charger since 8am this morning (10:46pm now.) So 12.75 hours on just the extended battery, I'm thrilled. I would almost say this battery would net me more time than 2 fully charged standard batteries.
I bought the Shell/Holster combo at VZW when I bought the phone. I could not get the shell to fit over the extended battery back without modification (as I've read elsewhere). However, I threw the shell in my oven for about 10 minutes at 200, and the plastic was pliable enough to wrap the phone. It then cooled down and now fits great. A little snug, but it functions perfectly (actually fits better in the holster IMO). I would highly recommend the extended battery. I can see why everyone is saying great things about it now..
The salesman at the VZW store got me 25% off for something (Forgot exactly why I got the discount) and they had one in stock. So I would definitely encourage those to go to the store 1st before buying online. (The salesman, who was a manager, said the only reason they had them in stock was because their store has sold so many of the Pro's).
the has gotten better since we got em but i thing i found which seems kind of weird is im getting better battery life with my screen brightness all the up and my battery manager set to performance
I just got my extended battery in the mail yesterday. I am noticing a huge improvement in battery life with the droid pro. The annoying thing is the back for some reason does not "snap" into place properly. Not too sure why, but putting a piece of folded paper underneath the cover seems to have done the trick.
To anyone seeking to further extend their battery life I recommend getting the extended battery from verizon. If that is still not enough you can buy the Energizer USB rechargeable battery and go from there...
Hi,
I recently flashed my G2 to the leaked T-Mobile gingerbread release: so it's not rooted or anything like that. I'm not using it any differently to how I was before.
The upgrade went very smoothly. However, the battery seems to be draining a lot more quickly than prior to the upgrade, and Android's battery usage app points a very damning finger at the display: currently it's showing 67% usage, and pretty consistently shows a high usage most of the day.
Before, I could consistently run the phone for the whole day and charge overnight, but now I'm finding that I have to charge it a bit during the day too in order for it to make it to the night.
I'm pretty sure that I'm not using it any more than usual, and I pretty much always have brightness set to 20%.
So my question is, what could be causing this? Could something be using the screen when it's not supposed to be even though it's not showing anything? Could it be a battery calibration issue? Maybe the power usage app in gingerbread calculates what it attributes power consumption to differently to froyo (though that wouldn't explain the overall reduction in life). What, if anything, could I do to try and track this down further?
Any suggestions would be appreciated!
Some things I should add.
I really haven't changed my behaviour regarding how I use things like wifi, bluetooth and gps. In fact, so far I actually have one fewer gmail account set up on it that before the upgrade, so sync should be doing less work. The apps I'm using are all about the same.
When I said I could use it for the day, I mean it would often end the day with more than 50% battery left. On some days I'd get it down really low, but that would be due to obvious extra usage, which isn't the case here. Occasionally I'd let it die completely. I always charge it fully overnight.
Finally, here are the other top items in my power consumption list at the moment:
Display: 67%
Maps: 8%
Cell standby: 7%
Phone idle: 5%
I seem to remember that before the upgrade, Cell standby and Phone idle were usually the top users of power.
no problem
Sorry, but I don't see any problem. Maybe its just placebo. This is the same on every android based phone. I Had HD2 and had 2 NAND androids till now and the battery stats were showing also display use 60% and then after new NAND version - gingerbread they were up to 80%+ but the battery was better than ever before.
Let me explain it to you. The display should consume most of the battery if you have 3.7 inch display and more. Maybe some navigation and 3G is the biggest sucker like the display but with normal use the Display. And if your display consumes lets say 75% of battery over when you are at 1% battery then it means it sucked 3/4 of your battery and just 25% other things did like phone idle and cell.
If it was before and your display consumed like 40% or less that meant that the other things like cell standby, phone idle consumed more power so it wasnt battery efficient. So its more battery efficient. Maybe you just have much more awake time than you did before. The awake time - sucks the hell of your phone(some apps warn you taht your phone wont turn to the sleep, which means your processor is still working hard which means your battery will deplete completely in a short time)
I experienced this also that my phone lasted only 6 hours or so and before it could wen to all day . Then I deleted some apps which were causing it and my battery was perfect.
and last advice. try to charge your phone via USB, I dont really know why it is caused but it will last longer , but on the other hand you will have to charge it longer. But if you go somewhere where the extra juice is needed then its nice.
With these steps my HD2 with old battery (about 1000mah left on 100%) went through 2 days of medium USE and about 5 days of just receiving calls and messages) so I dont know anyone else who could say that !

hope I helped you. GL a HF
If you can stand it, turn the brightness as low as you can handle . EDIT, you're already doing that....hmm
Not sure why gingerbread is giving you problems, personally I find it slightly better with battery than froyo.

Hmmm... placebo. By that, I presume you mean that since Display is ranking higher in the list now, that's making me think more battery is being used before. I suppose it's possible, but really it's more to do with how often I've been reaching that "I should charge" point, which for me is a function of battery level and time. If I get to 50% before lunch time, I think "I should charge". But getting to 15% just before bed I don't. What I've noticed is that since the upgrade I've reached the "I should charge" point every day.
I'm just very surprised by how the proportions in the battery usage list have changed, while a the same time the phone's battery usage seems to have increased, despite the fact that Gingerbread's battery usage is supposed to be improved.
One other thing that came to mind: perhaps Gingerbread's battery usage is just more accurate than Froyo's? It always seemed to me that the battery level used to work a lot like a car's fuel gauge: it would stick at 100% for a long time and then would drain. It was as though "full" as a concept understood by Android was a range rather than a limit, and so as a result the phone appears to drain more quickly, but it's actually just showing a more accurate battery level over time. Just a theory.
So last night I allowed the phone to completely die. This morning I switched on and immediately checked battery usage: display showing 99%, which is exactly what I'd expect. So I'll see how it goes now that Gingerbread has experienced battery exhaustion.
Personally, if I was upgrading from Froyo to Gingerbread, I'd prefer to start from scratch rather than doing an "in-place upgrade". I'd worry that maybe there are some leftover settings or files from Froyo that could cause unintended consequences. Consider backing up as much data/apps as you can (it's more difficult if you don't have root), charging the battery up to 100%, doing a factory reset, and then restoring and reinstalling everything back. Doing this will also reset Android's battery stats file, so you may find your battery levels maybe inaccurate while it's relearning the right levels for a few days.
Alternatively, if you don't fancy a factory reset just yet, you could try monitoring your power use with a widget like CurrentWidget which looks that the current draw rather than percentages. Also consider installing Watchdog Lite which might be able to help you identify if there are any processes using excessive CPU cycles.
EDIT: Just realised that if you flashed a leaked version, the install would probably have wiped everything anyway, so you can probably disregard the first paragraph.
Like the others have said, I think the screen usage being higher in 2.3 has more to do with the reduced usage of other apps and not the screen using more battery than in 2.2.
Think about it, most of the high battery usage items (web browsing, etc) also keep the screen on at the same time.
Yes, that's probably mostly because other things are using less power. I also suspect that maybe Gingerbread's battery usage app is calculating display usage differently: I just checked it on someone else's G2 (still running Froyo) and Display was way down the list. It dominates mine, even though I haven't used it that much today.
Today's power consumption has been a lot better. It's down to 39% now after 12.5 hours on battery, with 59% of that being attributed to Display. So that's not bad at all really.
Thanks for the tips on the monitoring apps. I'm already using System Panel (which only seems to care about apps and not hardware so much), but it's always worth checking out alternatives.
Couldn't it be due to you being in areas with bad connection?
I noticed that my G2 is down tot 30% after a few hours at school in bad reception+bad wifi areas. When I'm home the whole day my G2 is still at 60% at 10pm.
I have 2 exchange mail accounts set up to push and one gmail account...

My GF also has the S5 and at the same time last night she was at 11 hours (1.5 hours screen) and had I think 67% battery left.
Granted my phone was unplugged a little longer and had more screen time, but this seems crazy! Also her brightness was almost double mine. Unfortuanltly I didn't get any screenshots of her phone last night. Here are mine:

Note how the wifi has been on for 14 hours? It has NEVER been on, I haven't even connected to my house yet, I turned it off as soon as I left Verizon.
You can form whatever opinion you like. But the general concenus and my personal experience is that the S5 battery life is excellent if not outstanding.
You would do well to ensure that your battery is fully charged and use a good third party battery monitor e.g, Gsam or a similar app. It only takes a few poorly behaved apps to put a large dent in any battery so you should look for wayward apps and try to avail yourself of battery saving features e.g. reduced screen brightness, timeouts, processor governors and so forth. And perhaps consider looking into inverted apps.
