There is a problem with our battery life and we all know its true... I have even been given a new battery and HTC mains charger
I turn off any service im not using at the time (ie: wifi, BT, GPS, NETGPS,etc) not that I should have to do this, but lets story on track...
My battery will make about 1 day as I am A "power user" but if its not plugged in I wont have the juice for my alarm to wake me up, my wifes Sony Ericsson lasts 4-5 days per charge, but lets not compare apples and oranges, the whi-phone 3g my sister has sahe bought it about the same times as my g1, she hadn't ever heard of "deep cycling" 2-5 times when you get a new phone, she never lets it discharge fully and just tops off all the time, AFAIK she is treating a NIMH cell exactly the wrong way, BUT SHE GETS 1-3 DAYS depending on the type of use, and never turns off ANY of the 3g, gps, net gps, wifi, BT nada and Id say she uses hers alot because its her primary camera, GPS & A/V player
my question is WHY?
Im sure there must be somebody involved with the development of this phone/OS that reads thru here, since there is more exciting stuff coming from XDA than there is the market...
Im gonna add a poll that pertains to battery use...
I wanted to add one very negative one but hit submit not preview, maybe just post and dont vote if none apply..
they better come off a new battery almost all other new phones will get 1-2 day + average use, Ive had phones that could go 3-4. but the state of the art G1 mindblowing innovative phone wont even work a whole day, so what if its bigger than the whi-phone, it has no keyboard.
I for one would like to hear some solid info on a replacement battery and back, for new and existing G1 users, early adopters got the fuzzy end of the lollipop on the HTC->headphone jack adapter I got the headphones with the htc angled adapter from fleabay, so many manufactures stick it to the early adopter, when we are the ones that get the word of mouth going, as people go "WOW that thing is cool!,what is it?! they know when we bought out phones and should be able to figure out when the head phone rev change was made, so send them to the first of the buyers....
IF the battery issue isnt fixed, alot of people will be very angry and the g1 will flop.
I think the bad press is starting to out weigh the good press the G1 and possibly android as a whole is at a crossroad. If the g1 tanks Android will be stained forever...thankfully enuff I dont think XDA-DEV would give up on this badboy, I love this thing, and I love it for what it can be

Well stated sir.
HTC/Google need to fix battery problems in G1. Maybe it's soft bug, but maybe it's a hardware bug - Nobody knows
I dunno. With normal use, I get about 12 hours or more from my stock battery. That's about the same as other HTC phones I've had.
there is a battery issue and we are al aware of it.
i have managed to have it last through out the day
just set the brightness to the lowest possible, sleep time to 15 secs
turn off data and wifi and anything else that you are not using
its not how the phone was intended to be used, but it's what i ave to do for now
I find it fine for everyday use. Of course I haven't done a full test but maybe tomorrow I will.
I would like to use my G1 like I use my WinMo but no way I can with the battery.

I think you're exaggerating here a little bit. The battery life, while it got press at first, has faded from the limelight of android news for the general population. The G1 is already far from a flop and I don’t think there’s going to be a sudden mass return of all the handsets sold.
Let’s face it living on the cutting edge means you will get cut sometimes. Your high expectations will not always be met and manufacturers will frequently not care. The battery life is less than what many people expected, but we’ve learned to deal with it. At least we have options (power management, backup batteries, and expanded capacity batteries), but I’d not hold my breath on HTC making any major moves. How long has the issue been going with the TYTN II drivers anyway?

I have no idea what kind of use gets 1-3 days, but it certainly isn't 3G web browsing. Most iPhone 3G battery life tests clock 3G data use at about 3-5 hours. Based on my own usage of a friend's iPhone 3G, that seems to be about right. Coincidentally my G1 gets about 3-5 hours of 3G data use as well.
Frankly, from an engineer's point of view I have not seen any power drain tests conducted with enough rigor and variable control to be worthy of being called a truly scientific analysis. Even the best "battery life tests" out there aren't declaring what type of testing environment (los and distance to closest 3G tower), what background apps are installed, ambient temperature (which affects the battery discharge profile), etc. Without considering and removing these variables from the test, deviation could be as high as... well there's no fixing the percentage really. It's all just junk data.
I do notice after I installed Task Manager, to close out programs I am not using my battery life went up. There are a lot of un needed start up apps.

Yep my friend has iphone and we did test last weekend, both went 3 hours and change then died. If i dont use internet and set timeout and brightness down plus use task manager mine will go as long as my dash. I personally dont care about the battery life, i have a computer, home charger and car charger and i drive for a living so if it gets low no biggie. In my opinion i dont see android going anywhere and i love the g1. Just like wm its gonna take time to get off the ground. To say its at a crossroads is ridiculous.
I am using ADP1.1 and yea if I am browsing the net with 3G for 3-5 hours straight I start seeing the battery go down. But from 100% to 0% takes me longer than 5 hours. I know because I like to lay in bed and don't care to come check my messages LOL
I bought a G1 last week and so far I have been really dissapointed. After having an elf and seeing other htc phones I was expecting big things from the G1.
I am now a week into ownership and after 5 full charge - discharge cycles I am managing to get 24 hours out of the phone with next to no use what so ever. If i check my emails and do 30 mins browsing the phone is dead in 6 or less.
The hardware is simply put 'very poor' my screen is wobbly and the back is loose, all this after just a week.
As for android, it is fantastic everything I expected (except hotmail support) and there is no way it is going to flop. Its just a shame that google and htc didn't wait until they had the right phone for the job.
Thats just my 10p worth!!

It all depends on what you have installed. for me the start up is. I beleve amazon does too, but I uninstalled that. But the first thing I do is go into task manager and kill everything. And only like two things auto start up. I really with HTC built in a x-button app for android. I loved the click x for close.

Under light usage I get about 36 hours from full charge to shutdown. That's GPS on, Bluetooth on, Autosync on, periodically doing e-mail and web browsing.
Under heavy usage (Which is basically I listened to MP3s for 2 hours) it goes at least 17 hours before I plug it back in. I haven't tested but I'd bet it could go 20 or more.
That's as good as (or better) than I was getting on the Wizard/MDA.
I dunno if anyone has stated it but the problem with the battery has to do with the phone recieving the cell signal. For some reason the phone runs in overload when searching for a cell signal...I noticed this one day when T-Mo suspended my service and my battery meter never moved all day, I think by night it was down to 85-90%...sure enough that night when I paid my bill and the phone started picking up signal again, the battery depleted at "normal" speed.

Why do i keep hearing that there is no hotmail support? Android (and G1) works with hotmail just fine! Just go to the Email program and set it up. WHY!! .. I am having connection errors sometimes though..
Battery is a big issue. Never had any luck with it.. EVER.. just unplugged it and after about 1+ hour it's down to 66%. Played a game (slide puzzle) watched 2 youtube vids of about 3 minutes each. And I had it fully drained and recharged a couple of times in the beginning. It didn't even took 10 minutes to drop from 100% to 89%.. But I was on wifi.. Maybe this is normal.
Software has a lot to do with this I think. Yesterday I had about 50-60% left. Did something, can't remember what, opening programs or music. And closed it. After 5 minutes I checked and battery was hot and had drained to orange level. I checked with task manager and only calendar/messaging/tunewiki/music was on. I closed all and restarted the phone, cuz it was still hot. Luckily it lasted a few hours till I got home, with very carefull use..
So as I mentioned in the battery life thread, in the T-Mo store, the Galaxy was reporting 2d5h on and still had 32% left in the tank. Obviously that is without SetCPU or anything and people have to have been playing with it. Even not, 30%/day not being touched is pretty good. What have you guys done for battery life? Have you noticed the "ramp up" time that is always claimed by cell phone manufacturers? Mine has sucked today but I've been beating the hell out of it. I'm going to charge it and let it stay unplugged overnight to see what the standby drain is but what is everyone doing? Have you messed with SetCPU at all?
Thx

Who cares, I'm buying 2 spare batteries from Ebay, just like I had for my G1. I can go thru all 3 batteries on my G1 while at work for 10hrs. So, I'm assuming I will get similar results.

Haha I know what you mean. That's what I love about having a removable battery. Who cares right? Swap it out and you're good.
As for my experience, the battery live has been good. The battery status bar up top is not accurate though. Similar to the reception (bar) problem how it shows no bars but you actually have great signal. I'm sure a software fix will be available soon for this. Very minor.
Here are some things you can do to improve battery life:
Remove all unnecessary widgets off your screen. I had an analog clock on there and when I removed it, I noticed better battery life just from that. No joke.
Turn off the live wallpapers. Those drain battery too.
Turn off wifi if not using it
Turn off bluetooth
Set the notifications to refresh at a longer interval instead of like every 5 mins etc...
If you're really nit picky, check "use only 2g networks..." - I personally wouldn't.
Adjust your screen to the lowest brightness. I love that it's an SAMOLED screen, because I could never get by with the lowest setting on other lcd screens.
Hope this helps man...enjoy!

By the way....regarding non-OEM batteries....I do notice that they are all 1500mAh (like oem), but I've always had a stigma about putting generic batteries into expensive devices.
I guess where my stigma comes from is due to my past experience with my digital camera, when I took photos of a wedding and my files got corrupted. My only explanation was because I was using a non-oem battery, because ever since that I've only used oem batteries along with that same memory card and have never had a problem since. It's been 3 years.
Since the non-oem batteries are 1500mAh, it shouldn't matter right? Now that I think about it, I do remember the camera batteries being of a higher mAh than the original battery...I know this only has to do with the capacity, but as for the voltage output, could there have been a strange surge to cause the corruption?
I know I'm just being paranoid, but just thought I'd get some input from those who know about the mechanics of batteries and the likelihood of any malfunction due to it being a cheap non-oem battery made in china.
Any thoughts would be appreciated.
My biggest battery drain was use wireless networks was disabled by default. All apps that tried to get my location therefore turned on GPS. One widget was bugged and would keep using GPS, killing my battery overnight. Uninstalled the widget and enabled use wireless networks and only lost a percent or two overnight. Make sure the GPS icon is not consistently on when not using Google Maps and whatnot.

This didn't really do anything for me. Under usage it definitely uses less battery than my N1 but standby SUCKS. How did the one in the store get 2+ days. I switched from GSM/CDMA Auto PRL to just GSM Auto PRL. I am switching back. WCDMA Preferred actually got me better battery on the N1.

The Amps and Volts are important, but in a battery is only a small part of it. The quality matters, the drain matter, it's max input matters, it's sensitivity to fluctuation, sensitivity to over charge... etc etc etc...
That being said, most modern devices these days have a lot of internal fail safes that should try to stop anything crazy from happening... because really the battery could have any amount of amp hours rated to it, how much it can and will output is what matters though. You could theoretically make a battery the size of a car battery for the thing that with 1500AH (aka 1,500,000mAH) would give you a retarded amount of standby time as long as it was rated about the same on everything else... although charge that thing wrong and you would have a pretty cool fireball...
an app called juice defender seems to work pretty good for me on the vibrant (ultimate juice is the paid version with all the features). I previously used it on my cliq and had good results also.
what it does is disables apn and/or wifi and you choose what intervals it comes back on. example - you could have it come on every 15 minutes for 1 minute at a time to complete necessary syncs. you can also set up night schedules etc.
I would recommend this app if you're lookin to save some battery. it also has a little widget to show you how much battery you have saved. not sure how accurate that is though. good luck!

Is it cool to use the home charger for the nexus one AND the Galaxy interchangeably?
I ask because I'm ignorant to the amps/differences. It would be lovely to keep one charger at home, and one at work.

I stopped caring. As long as it has enough to charge to stay on between unplugging it in the morning, and plugging it up at night, I'm golden. I've had the phone since launch, and I've only charged it up twice, so that's about two days between charges. I got it with a roughly 60% charged battery.
I use BatteryLife by Curvefish to see my battery usage.

Galaxy S/Vibrant charger is 5v @ .7A. I think I read that the N1 wall charger is 5v @ 1A. It'll charge a little faster, and will probably heat up the battery more, but it shouldn't destroy the phone. I'm sure somebody smarter will correct me, though.
I'm only get 1.08x at the moment, is it still serving a significant purpose or is it just using my memory? (as in not worth it)

I thought yay at first. Now, I'm not sure. I toggle my 3g data on and off as needed. I'm also not sure if JD slows down my phone.
Nay. I figure if you're going to turn every bloody feature of the 'premium' smartphone that you're paying for, just to save some battery, what the hell was the point of getting the EVO over a blackberry?
Sure, I get a whopping 8 hours, if I'm lucky, out of my evo, but I have 4 batteries, a car charger, one at grandma's house, one at my office, one by my bed, and I can make it through the day. It lasts 4 hours on hotspot while I'm at college, too, then I just swap batteries.
I say nay. I used juice defender for a week or so but I find that its better to carry an extra battery around if you need the additional juice.
What they said.
I used it for about two weeks after getting my phone, it was great... mainly because i still had "new phone effect" where the screen was pretty much never off, and i needed every battery savings possible. I just use SetCPU now to lower my clock slightly when my battery is getting on the lower side, have an extra battery in the car, as well as a car charger.
I say yay. Before cm7 I was getting 2.13 times battery savings on it. I will be happy when they update it for gb.

I get my battery savings from Tasker and SetCPU. I turn things off and on as I need them (automated with Tasker) and SetCPU slows my phone down as my battery dies. I always have an extra battery with me and a spare at the house as well. I use a charger at work if I need it and I have a charger in the car as well. I don't consider my power issues to be issues at all, really.
I fall into the herd. I initially thought it was cool, but I based that on my WM experience. I think the kernels that are out and SetCPU are all that I need. I use my phone a lot and get, for me, great battery life. I also use a charger when I can. I would rather charge than cripple my phone. That is one of the primary reasons that I left Windows phones.
I use tasker. Better. I just have it turning mobile data on and off.
Having tried just about everything to prolong the life of the battery on my Desire HD, I think that I have, at last, found a real solution.
I did not like the idea of buying a spare battery mainly due to the flimsy battery compartment on the phone and the thought of constantly swapping batteries. Swapping batteries would also involve switching off the phone and losing data (for example, if you are using GPS to track your movements).
I have tried lots of software solutions, most of which help to give me an hour or two of extra life. My favourite software solution is Juice Defender, which works well within the limits of HTC's awful battery.
Someone on another thread recommended the TechNet external charger, which packs a 5,000ma charge - enough for four full recharges of the HD phone. It plugs into the micro USB port on the phone and charges the phone as though it is connected to the power supply. It hot-charges, which means you don't need to swap batteries or switch off the phone. The device comes with lots of adaptors to charge lots of different devices. There is also an 11,000ma version... enough for 10 recharges.
Available on Amazon:
http://www.amazon.co.uk/gp/product/B000NDQ92W/ref=oss_product
It also looks good and comes with a travel pouch and is smaller than the HD phone itself so slips into a bag without a problem.
Looks promising. Thanks for the info bobby!
I purchased this before I went back to nz for Xmas. Well worth the purchase, has saved me several times. One thing to be mindful of is that if you accidentally turn it on without realising, the battery will drain, even if its not charging anything.

Is the battery really that awful? I can use the phone for 24hrs (including stand-by time, 14-16hrshrs of usage time) with wifi, 3g constantly on until I need a charge.
Which is really more then enough time for me in between charges, unless you go on trip for days without access to a computer or an wall socket.
Its nice to have a phone which last for days like the old days, but it really has no inconvenience charging it once a day, right?
+1 , left my phone in work the other day after reasonable useage in the time I was in work 0900-2000, came in the following morning , to find 13% charge remaining and that was in-spite of my alarm going off
I find that if you put your phone in power saving mode, even the remaining 10% can last you for almost a day.
Its quite useful if you know you gonna leave ur phone for a period of time.
Actually it would be quite useful to have a toggle widget to do that on ur home screen instead letting it activating itself below a set percentage. Is there any?
Howdy,
I was so frustrated with the battery usage I nearly ditched the phone. I decided to apply a different rom after reading and considering many posted here I went with Coredroid, which I downloaded from this site. (had the original vodafone rom) Great support and documentation and tons of help if it goes south.
I can say as of now my phone is 5 times at least faster and the battery life has extended 300%.
When you check battery usage the I found the number one battery killer is Display. With Coredroid its about the 5th item on the list. Wireless and bluetooth and the biggest now (if you can call them real big) but they are easy to turn on/off.
I was very nervous about a custom rom but I needed something. I can only recommend you look at other roms apart from you stock one -Im assuming. (Im not sure what warranty etc rules are gone, personally I don't care)
Cheers

Yes, that was me, with the external battery pack/charger
Well, it's a heavy phone already, a huge screen to light up and render -it's pretty clear where the power is needed. But would the bulk associated with another 400mah really have tipped the DHD over the edge?
Anyway, it's designed now, and nothing can be done about that. I'm quite happy with it lasting until the night for normal/heavy usage (about 16 hours) - with it's out-of-the-box form factor.
And for those occasions when I'm using GPS tracking apps out in the open for 5-6 hours, broadcasting my location to a website, hooking it up to the external pack (mine is in fact a New Trent one, 5000mah) means it won't drain unexpectedly. That is, with 5000+1260mah combined!
The battery pack provides a "full" charge in about 2 hours, that is just like a mains charger (it is rated up to 1amp output, providing of course whatever amperage the device pulls).
That pack might be a solution for the battery problem, but I still don't think it's enough. I don't think that you should have to buy a portable power pack just for your phone battery to last. The whole point of mobile phones is that you have access to a medium of communication in a remote location. By not making the battery life long on a phone, I reckon HTC are actually limiting its main use. But that's just my 2 cents, and it does depend on how people like to use their phones.
5000 mah is not enough, why not make it larger
Thanks for the info.

You must love the 1240Ma battery that comes with the phone.
You've enabled USB Debugging, yeah? I get 2 days, and I work in the middle of nowhere. The phone polls for a new cell constantly while I'm in my office.
If signal is good in your area, tell the phone to use GSM or WCDMA exclusively. Otherwise it will switch to whichever has the better signal, which can be problematic is you're in an area with good / poor coverage of both technologies.
I think the polling thing might be a big battery killer. I shall try that.
I friend of mine in the office, use to have a Sony smart phone that barely lasted a day and thats on standby. He ditched that for a DHD. His battery now lasts 4 days plus, with minmal use! Mine on ther other hand with minimal use can give 2days at most.
The difference is that he is on ORANGE and I am on T-Mobile. It must be down to signal strength because he use to be on THREE and the signal strength was very poor at his home location.
BTW, I find that Juice Defender does help and switiching off Flash in the browser.
This charger and the USB-Batteries are the best inventions ever
It would be great if this phone got accessory support like the fruit phone does. An extended battery case would be the most optimal solution to this problem but I haven't heard of any out there yet
P.S send me a PM if anyone finds an external battery case
how is it compare to eneloop 5000mah?
Ah! I need that one for when i go camping
Hey guys. I'm wondering how much better the battery has gotten since the first week y'all got it, to now.
For me I'm satisfied with the battery and I've had it for 4 days. I get about 2-2.5 hours screen on time with fairly heavy internet usage, texting, etc.

For me I'm satisfied with the battery and I've had it for 4 days. I get about 2-2.5 hours screen on time with fairly heavy internet usage, texting, etc.

Are you taking any measures to save battery life, like certain screen brightness, disabling of certain features or radios, undervolting or CPU/Governor changes, etc?
First thing I installed on mine ( haven't had mine a week yet ) was Battery Monitor Widger Pro, since I've used that on my past devices when I was testing out generic batteries (speaking of which the 8$ ebay 3800mAh on my Desire-Z is still kicking strong after a year).
Problem with estimates, is that they are basically just that, and the difference between browsing on mobile vs browsing on wifi or mix, and your reception quality can also have an impact on your battery. (in the end, your screen is the biggest impact).
Mine lately, say if I had it charged at 100% , it'll take about 2 hours on mobile to get to 91%, with the screen being on about 25%-35% of that time (auto-brightness), receive/send text, take out of pocket to check email or facebook notifications, and so forth. Which would normally show as screen 30%, Google services 13%, Wifi 9% (when I had it on between house and destination). Phone idle 8%, Android OS 7% etc.
The widget I mentioned earlier can basically monitor your draw from time to time and if the screen was off or on and such during those times (default interval on it if using a widget is around 10 minutes on the logging, shorter may actually impact the battery it's monitoring oddly enough)
PS: The other day when I actually drained it down to 0% it took about 5-6 hours

I had about 3-4.5 hours of screen time other moderate to heavy usage on my first week as I was testing it's battery life. As that I just used my phone under light to moderate usage. My brightness level is always at it's lowest but when I'm outside I turn it up to about 50%. I rarely play games on my device. I read a lot on my phone. I use my phone to record lectures in class and do a bit of homework on it. 7 months later and I'm pretty much doing the same. I have a custom kernel installed and I'm really confidence about it. I carry a external battery pack with me all the time but I hardly use. After having a custom kernel for the past 7 months I can say battery life has been relativity the same screen time wise. I learned how to manage my apps so they won't prevent my phone from sleeping to save power. Your mileage will vary depending on what you're doing on your phone and how you manage your device. Cell service is crucial to the phone. If you're in area with little to no service your device will use up more power to stay connected. This is when "Airplane mode" comes in handy.

Nah. All stock, not rooted yet, auto-brightness, No auto sync. I don't get very good service at my work and I was about 28% without service during the time I was there. I would get on facebook and message people on facebook and text, surf the internet etc because it was slow. I had maybe 2 hours screen time and 8% battery life when I left work. It was probably 9 hours off the charger. Here. I'll post a screen shot after this post (On my computer right now)

One of the benefits to custom roms (though 'stock' on a nexus is well AOSP so...) is the ability to tweak that stuff to finer details, top it off with a custom kernel and can optimize even further. Just a matter of how far you want to take it.
I have a history of immediately rooting anything I get my hands on, so I tend to have very little experience with stock. But the Nexus devices are probably the only ones I could survive having stock (but rooted) as opposed to say touchWhiz on samsung.
I can say that this phone charges FAAAAAAST.

Coming from the the backflip's motoblur to the Captivate's touchwiz then onto One X's sense to AOSP.. I'm going to stay android purist from now on. I'm in love with AOSP

At least all the available kernels work just fine with AOSP. (Francos seems to be pretty popular for battery, I prefer bricked though on both my N4 and N7).

Why do you prefer them?
So with battery monitor widget pro do I just let it run and collect data?

Guess tonight I'm going to work on getting it drained down to 0% just remembered it was my N7 that I did a full cycle on with monitoring, I haven't done so yet to the N4.
PS: I usually do a dual-graph (mV and mA), but in this screenshot you can see generally speaking with my current configuration, I tend to drain around 200-300 mA screen on, and around -20-50 with it off.
PS#2 : It only went up to the -400 or so mA on the top right because I had changed my screen brightness to about half instead of autobrightness.

Additional options. Take for example the Bricked kernel for the N4 in my signature. This is it's feature list, it's not aimed for hardcore overclockers or such but gives you some options (The one for the Nexus 7 is a bit more configurable during the installation).
* Based upon Googles msm 3.4 source
* Various other fixes (look @ github)
* Compiled with gcc4.7.2 toolchain (linaro 09.12)
* -O3 optimized
* Snapdragon S4 & CortexA15 optimizations
* Sweep2wake
* 192Mhz min clock
* replaced qcoms hotplug binary with msm_mpdecision (IN-KERNEL, better battery life + performance)
* Extensive sysfs interface for mpdecision with all the tuneables you want (/sys/kernel/msm_mpdecision/)
* replaced the thermald binary with my IN-KERNEL solution. (/sys/kernel/msm_thermal/)
* export krait version to: /sys/kernel/debug/krait_variant
* modified ondemand governor
* Allow OC up to 1,83Ghz, faux123 (from a thermal point of view that is now SAFE)
* Fixed min cpufreq resets
* Undervolting (faux123)
* Default clocks: 384min & 1512max

Sweep2Wake is kind of nice too, you just slide accross the screen to turn it on without having to touch the power button (And yes your phone is still asleep doing this, it just works off interupts.)
other kernels can be a bit more involved, such as being aimed towards overclocking the CPU or GPU, or adding in extra features not normally found in stock, and so forth. I've had the best luck with Bricked and Francos'

Yep, if you have a widget on the home screen (I usually do 2x1 size) it'll collect every 10 mins by default. If you don't use a widget you'd have to check a box in preference to monitor without widget or it won't log times (note for example the missing 'blocks' from my history log).

Speaking of battery, anyone ever gotten more than say 800mA charge on their N4? Cuz even on my old Desire-Z if I plugged it into a 2.1A charger it would actually charge up around 1300-1500mA, but with the Nexus 4 seems that even on a 2.1A port it rarely charges more than 500-600mA.
It'll probably become more accurate once I actually drain it down to 0% and have the widget record it's history from 0% to 100% since it bases a lot of it's mA estimates off that (ie: off the rate of decrease of the battery's mv since batteries typically have a certain voltage once they hit near 0% and when they're at 100%, comebine that with what it knows the battery's mA to be it can determine the charge/discharge based off that).

I can get back to you when I figure this app out more and start using it.
What'd you say your screen on time usually was?

Just in the last 2 hours or so, probably 30-45 minutes. I was in the car so it wasn't coming on all that often. Since I actually have the widget on my home screen now, I'll just post an update again probably in the morning as I play with the phone some more, maybe play a game or two (I'll set a Market in the battery history before I start and after I end it).
Far as figuring it out, it's pretty easy since most of it is already set up by default once you open it. You can basically just pop a 2x1 widget on the home screen and just leave it.
My battery life has improved drastically by just sticking with one setup and letting the phone get used to it. That means keep the same rom and kernel so the phone settles in and gets used to it. After a few cycles your usage should increase.
I recommend straight CM 10.1 with Franco kernel.
Also use 2g instead of HSPA+ when you're not using data to save power.
If you're using touch control, don't, it drains more power for sure.
Undervolting helps too.

Can you clarify on this, other than the power/volume there's not much else to actually control the phone with.

The app 'touch control' , many nexus 4 owners use it to wake and lock the phone using touch gestures in place of the traditional power button. In my usage it definitely drains the battery quicker.

Oh you mean like Sweep2Wake in the Bricked Kernel I'm using, except that doesn't use any battery cuz that's in the kernel using interrupts rather than an app that would keep the phone awake. (course that's all it does too, wake, nothing more sophisticated than that).
But yea I didn't know about that app.

So yeah. You should drain it then report with some screenshots.
It's at 44% right now
