Is 3g signal the same signal if I turned it off and just had 2g? Why I'm asking is I usually have 0-1 bar at home and I know poor signal strength causes battery drain. If I go 2g will I have more bars or the as I would in 3g?
I'm asking this because I have been told when I bought my last phone.. tp2 that it had to have a data plan or nothing will work. So my question is and have asked before but never have gotten a response is.. if I turn data off.. will I still get incoming sms? Im I better off getting juice defender then? Will this help? That is.. is sms workable with data off.

SMS is 1X. You don't need data for SMS texts. Texting is available on even the OLDEST non data phones.
Now, if you turn off data, you've pretty much eliminated most of what makes a "smart phone" smart.
Spare batteries are cheap, as are several different chargers. One for car, one for office, one for home, one for travel, etc.
Better you get into the habit of whenever you're near a power plug, to plug it in and let it charge. Once it becomes an ingrained habit, you'll not worry about battery life as much and you'll get much more enjoyment and use out of your phone. Besides, better get used to it. Processor speeds, power hungry hardware keeps advancing, battery tech doesn't.
I have 3 batteries and a tp2 I use to charge the others while not in use so always have a full battery. I don't sync anything but my email. I can always turn the data back on for internet or anything I'm using for internet. Why I mentioned juicedefender... also I underclock and undervolt. Just looking for a longer battery life. I don't get more than 4 with moderate use.
Edit: one doesn't have to get use to it if there are ways for longer battery life. I'm sure you have all the accounts sync and checked, screen brightness set all the way up, 4g on, gps on, and overclocked and saying get use to it its a smart phone.
I don't have 4g and I do use the internet a lot and check my email. I get my email to sync when I chose to look at my email and don't need to check every so often wasting my battery. Not everyone uses all the stuff you can use the phone for or as much as someone else.

You're saying you only get 4 hours life?????
I keep wifi on, BT on, data on.
Between 8am and noon, I've browsed, made 2- 30 min phone calls, updated 3 apps from the market, played (shhh, don't tell my boss) 3 different games for at least 15 mins each, checked the local news. and I'm at 82% using the stock battery.
Also, have exchange push enabled, gmail pull at it's quickest interval, NOT overclocked, not running any task killers. No 4G here, so that's off and GPS and NETWORK location are also both off.
If you're down in 4 hours, you have a different issue. Better install a few monitoring programs to see what the heck is going on.
Granted the 1500mah battery is way too anemic for this phone, you should be able to do better than 4 hours.
I agree you defiantly have something going on causing a battery drain. I used to get 6-8 hours with moderate use and have worked a lot of different things to finally get up to 14016 which i am happy with (i still dont see how anyone gest 30-50 unless there "moderate use" is not touching the phone except to have 1-2 calls or something on the break.
i recommend the paid version of system monitor. it lets you see your battery drain cpu usage and device usage. it also has a history option that will let you see which apps use the most power. The only other thing i can think of is you have an app preventing the phone from sleeping so that your setCPU profile and juicedefender are not doing anything most of the time.
as far as turning data off. You can receive SMS, you receive phone calls obviously, you can not download MMS or anything else requiring internet data. there is nothing wrong with turning it off when nothing use. (i personally use ultimate juice so that unless i have my screen on and unlocked or my phone is on the charger data is off.

Mind sharing your exact setup? Rom/kernel etc. Seems like your getting pretty good mileage.
I leave my phone on Wifi all day at home (no signal either, 1-2 bars) and battery drain is minimal now and it's not constantly looking for a data signal. I go approximately 30+ hours on 1 charge
I have the system paid app already. My problem is I have the worst reception where I live. Usually –105 to -118 and -120 I heard is no reception at all. So its more tower pulling and increasing voltage to get a reception. So I'm trying to do what I can to save a little battery...

Rooted stock, deodexed. Netarchy kernel. Have old airave at home for voice, and at home, I use WIFI. GPS doesn't seem to have that big of a drain
I was slightly incorrect, I do have setcpu profiles. Thought I had them off, but they are on, but NOT overclocked. For battery >75, or on power, default max, 384 min, conservative. Screen off, 384/384. Brightness is NOT high as I work in a well lighted workspace. Sometimes I do turn off WIFI tho. It'll fight with bt on occasion. Same freq. But usually it stays on. I do use phoneweaver for profiles. And I also use TASKER to create specific app profiles. IE turn on gps, wait 15 secs, start gps capable app, turn off when app closes, etc.
I also did the battery calibration "trick" and every now and then I clear the battery data from recovery. Not sure if that helps/matters or not.
I don't use the camera app, nor do I use friendstream. GTALK (known battery killer) is set to NOT running/syncing.
Is it great battery life? no, I'd say average. About what I'd expect. I'm not expecting 24 hours with it while using it and not recharging. When I'm out and about, I'll plug it in any chance I get, and also have spare battery or 3 from my TP2. For a full charge, I have an external battery charger. I was using the TP2 as a charger but don't trust it's charging circuits either (yet another HTC product. lol)
I just checked and I'm at 49% assuming the "battery guage" is accurate. 8 hrs to 49%. Few texts, another call, some more news, using TIKL. Time to plug it in and let it charge. But it was a nice test to see how long my normal use would last.
If your signal is that low (to the OP), try to get an airave, esp one of the newer ones with 3G/EV capability! I am going to call and ask if they'll replace my older one with the newer one.
I already thought of that option. Don't have internet here... downfall..

...and I've verified that the custom kernel was installed by going into About Phone. Is there anything else I have to do for the new kernel's advatanges to, well, take effect? I took off SetCPU since in the dev forum they were saying that the kernel itself will do what SetCPU did.
Sorry for the newb question. I've just rooted my phone and started researching a bit and wanted to make sure I didn't mess up or leave something out. The actual visual part of the phone looks the EXACT same as before I put the new kernel in.
I appreciate any help you give me in advance
I'd recommend you just use your phone like normal for a few days - if your phone is anything like mine, you'll see marked improvement in your battery life. The other day, with light use, I still had 30% remaining after 25 hours unplugged (without bump charging)... impressive!
I was in the same position a week ago. I installed Lou's #8 on my stock rom and it seemed to drain my battery faster. But I let it drain until it shut off and then charged my phone overnight. Turned it back on, and guess what? My battery indicator was stuck at 100% for like an hour. I thought it was a glitch, but it wasn't. That day, I had a 21 hour uptime... before I installed it, I could barely get more than 4 hours before having to plug in.

Does it matter when I allow my phone to discharge the battery completely? I will have to keep it charged and plugged in tonight because it's also my alarm to wake up to, but I'll have the battery dissipating all day tomorrow until it hopefully dies.

I don't think it matters. Mine conveniently died just when I was heading to bed that night. I do use it as my alarm as well. Thankfully, it was a weekend night.
Update: Running it today, haven't seen much change yet (but it's only the first day). However, how can I check to see what my battery usage is (I know you can check in "About Phone" but is there a numeral amount that would tell you guys something of significance)? Therefore if I posted something like that here people could tell me, "That really sucks, it's not working for you", or "Hey, working fine!"
Also, where I sit at work doesn't have that great of a cell reception, meaning maybe one bar if I'm lucky. Would having no cell reception drain the battery so much that it's almost dead by the end of the work day?
Would turning my wifi ON help the battery usage reduce some because the phone wouldn't constantly be searching for 3G?
Thanks again for everyone's help so far!
Wifi uses a ton less battery over 3g and low cell reception kills battery fast. Just let the kernel do its thing also letting the phone die is a bad idea. Our batteries aren't designed to ever fully die.

There are so many variables, I don't think there's any given number or threshold which will make us say "That really sucks, it's not working for you" ...
I've found that lack of cell service is the number one thing that will kill my battery regardless of kernel etc. I get between zero and one bars of (roaming) 1x at my house and if I set my phone somewhere that blocks the signal just a bit more, it can kill my batt. a lot faster. If your phone is using data throughout the day and you have a wifi signal available, I'd definitely experiment with leaving wifi on all day - that's what I do at home to have any data connectivity worth using. Using wifi like this doesn't seem to be too big a hit on my battery.
Also experiment with your phone to see if you can find a location or orientation which gives you a better phone signal - go to Settings -> About Phone -> Status and scroll down to see "Signal strength", this will be a number expressed as -dBm where the higher magnitude of the number (ie. -99 is a higher magnitude than -80) the worse your signal is. Keep in mind that this scale is logrithmic, so a change of magnitude of a few dBm indicates a fairly large signal strength change... So if setting the phone on the right side of your desk gives you -85 dBm and setting it to the left gives you -95 dBm, your battery will die faster with the phone set to the left... Keeping the phone in your pocket can really knock the signal strength down - experiment with the phone lying on your desk, check the signal strength and then cup your hands around the "bottom" end of the phone, covering the optical track ball and the buttons, etc... In my experience, just covering this antenna area like this drops my signal by 5 dBm or more.
One more thing which it sounds like you might be aware of already is that people report that due to small differences in hardware, these kernels don't work the same for different phones, so maybe trying a different one of Lou's kernels (or a different developers altogether) might work better for you (although trying each of the myriad kernels available sure sounds daunting to me). Good luck!
Any help is appreciated...I'm at my wits end with this phone. I've been unable to make it through a day of work since I've had it.
I charged the phone from 1130 to 7 am, at that point i shut it down and did the hour charge, at 8am when I got out of bed I turned it on, let it run 2 minutes, charged it for another hour +. When I took my phone off the charger to head out the door it was 9:14AM. Its now 11:10 AM and it already shows 79% battery. I've barely used the phone. (trying the HTC tricks or just letting it hang normal both seem to make no difference really).
Spare parts reports 9m51s used without sleeping, and 9.4% used, 6.6% screen on, 0.6% phone.
Wifi, bluetooth, 3g, and sync all off since leaving the house. I've done nothing but send a few texts and listen to a voice mail.
I dont get the best reception at my current seating area, but I am able to make some calls / get service despite. Could this still be the cause? If so - is there ANYTHING I can do to alleviate that?
I have CM7 02262011 nightly, build GRH78C - on zendroid CFS. I thought zendroid would help with battery life immensely (as many reported) but I've seen almost no improvement. At this point, I'm not even making use of the smart phone features - no wifi, no playing games, no browsing the web...as soon as I fire up a game the battery plummets. EDIT to add I've had this kernel and rom for about 4 days now, and I did clear battery stats after flash. All I've read would indicate this should be enough time for it to "settle out". Is that true? END EDIT.
At this point the phone is virtually pointless to me....is the battery life that bad? I see users talking about 18-20 hours with light usage - I generally put myself in that light usage category and I cant imagine making that mark. Any suggestions?
If your "time without signal" in battery usage is really high, that'll eat your battery super fast. Really, having a low signal constantly will do the same thing. Because where I live & work never gives me more than a bar or -90 dbm, my battery goes pretty quickly too, even without a high "time without signal".
I keep 3g, Bluetooth, and GPS off almost all the time & keep wifi connected at home. I recently switched to 2.37.6.2-SavagedZen-0.1.2-CFS-HAVS-WiMAX-Froyo+. I unplugged the phone 8 hours ago (I don't like to keep in charging overnight) and it was at 98%. When I got up an hour ago, it was still at 98%. My time without signal was 73%. I've used it heavily for the past hour & it's at 95% now.
My battery life isn't great by any means, but it's better than it was. I also use CPU Boost (a free app similar to Set CPU but with less options) to undervolt. I slightly undervolt to around 700 MHz while using it lightly & set it down to about 460 with a screen off profile. Since I rarely do anything that needs the full ghz processor, this doesn't affect my phone's performance & really saves battery.
Hope this helps

It sounds like poor signal is hurting you.. your phone may be constantly searching for better signal and killing your battery. Just be sure you have no wakelocks...
Also, when you wipe battery stats.. make sure you re-calibrate your battery as well. When I wiped stats it actually did more damage than good until I re-calibrated the correct way.
Thanks...I'll try under clocking a bit and see if it has a gain...I had that disabled up to now.
I put on ZenDroid-1.1.0-cfs-avs... (about phone shows it as 2.6.35.10ZenDroid) with anywhere from -96dBm to -104dBm. Could that be the explanation?
I'll have to monitor a bit more closely at home to get a better idea of service and battery consumption.
Thanks for you input and help though.
Anyone else able to comment on their signal strength and relative battery peformance?

Could you elaborate on wakelocks? I havent heard of this before... (ill do some searching as well).
Again, could you possibly comment on re-calibrating? I was under the assumption that was letting it charge fully and drain fully after a wipe of stats. I wiped stats on a full charge, let it run down, and then charged back to the phone reporting 100%. Was that incorrect procedure??
Thanks for your input!
Have you let the battery drain and than recharge several times? Part of letting the phone "normalize" for a few days is letting the phone go through several charge and drain cycles. If you get "scared" when it hits 60% battery and plug it in, your not allowing the phone to properly calibrate your battery percentage.
Also, go into spare parts and your battery history and find out what is under "partial wake usage". That will let you know what is being used when your screen is off.
For comparison sake I'm on CM7 RC2 (same results w/ RC1 though) and savaged zen 0.1.0 CFS SBC. I have one push email account, sync always on, wireless data on when no wifi, no bluetooth, and no gps. My screen brightness is always at 25%, which is plenty bright. I also have several apps running in the background like weather update once an hour, kakao talk, gtalk, etc. With Wifi on at work (NOTE: wifi saves TONS of battery over using 3g), I unplug at 7am and at 11am I'm right around 90%. A few texts/gtalk and about 30 minutes of web browsing since unplugging. I generally leave work at 5pm with around 70% battery left. However, after I leave and start using the phone more battery does drop pretty quick. I can usually make it to 11pm, but I use the remaining 70% in those 6 hours as opposed to my "work battery" which is only 30% in about 10 hours. When you start using the phone you are going to get fast battery drop. The large screen and fast processor are the culprits of that.
Always keep in mind. You have a mini computer in your pocket. You are not going to get days of battery life like you would with a crappy flip phone. Laptops with gigantic batteries last 4-6 hours, and your phone is doing similar work on a much smaller battery. It's amazing these things can get 20-24 hours of use.
Well after poking around in spare parts at the prompting of you all, I found that my phone was without signal for something like 81% of the day. I put on airplane mode and put wifi on and i was seeing normal drain. Oddly enough, it seems my HTC Hero was able to stay connected to the network better in the same "office location" - as I didnt see that kind of drop.
Regardless, its no big to kick on airplane mode for most of the day and fire up normal service on short breaks or whatever else. So issue resolved all in all. I appreciate the assistance prompting me to look into the spare parts and its various features.
Again, with airplane mode on my numbers are MUCH more inline with that of other users. Thanks to you all!

Yea, just gotta watch out for bad signal areas, as those are the biggest battery eaters. Some phones [of the same model even] handle areas differently than others. So if, like in your case in a bad area for extended periods of time, kick on airplane mode. Also like also said, turning off your 3G when not in use is also a big battery saver.

Ditto! I wiped stats without knowing what they did, found that it got WORSE. Then I looked up how to actually calibrate. My battery life rules now
I also found that calibrating your battery helps. I realized that if I unplug and then plug my phone back in almost immediately that it has to charge a little more to get back to 100%. If you do a search for calibrating EVO battery you'll find detailed instructions.
Friend has a new Desire Z (bell, unlocked). Using it on AT&T network.
When at a house, and we use WiFI (30Mbps DL, 25Mbps UL), the speeds are VERY inconsistent. With my iPhone 4 using speedtest.net, it shows up as 20/15 each time. (WiFi is a little slower than the modem).
With the Desire Z, we get 15/10 (which is fine/acceptable). Then 3 minutes later we do it, we get 5/2. Without even moving the phone or touching the modem connection (not downloading anything on the computer), the connection just gets slower. Then it might be fast or slow, basically it's a toss-up.
The first time we noticed the issue is because when we are outside, we get HSPA speeds of 2.5/1.0, then randomly decreases to 0.1/0.05. HUGE difference. And VERY inconsistent. He is using a microSIM from iPhone 4, with an adapter, so we figured maybe the SIM card is getting loose at certain points? However, the WiFi is also inconsistent in addition to the HSPA, so it's probably not that.
What should I do? Is this the situation where I have to flash a new radio or something? (Please suggest others if I am wrong).
Thanks!

Also, his battery is kinda weak. The battery health is apparently clean/healthy. He came from an iPhone 4, where he would have 3G, WiFi, and GPS on at night but not actually using them. Wake up, and 3% battery loss, maybe 5. WITHOUT using them, just having them on.
Now, with the Desire Z, we have the WiFi + 3G on, but NOT the GPS. He is losing 20%-25% in 8 hours without even using the phone.
Information about battery shows a high Cell standby (25%) and Phone idle (25%) percentage. When going into Spare Parts > Partial Wake usage, we didn't find anything really fishy. BUT we had rebooted so perhaps some info may have been lossed. Should he just go to sleep tonight and report the Partial Wake Usage statistics again?
We have a feeling it may be some apps refreshing at night.. But he clears all the apps with Advanced Task Manager except for like Facebook (2 hour interval refresh), GMail, and Google Voice.
I highly doubt a 20% battery decrease overnight is normal.. My mom's Atrix only loses about 5% overnight, with the same parameters I gave before.
I thought it may be a bad battery, BUT the phone idle + cell standby are abnormally high.
Thanks!
Does anyone have an answer? I was wondering this
I have been running CM 6 since November and just recently flashed CM 7. On both ROMs, Cell Standby and Phone Idle have been very high on my list of things that are 'draining' the battery.
For example, today Cell Standby shows as 37% and Phone Idle as 30% for me.
In fact, its very rare that these two things aren't at the top of the list of things that are using the battery for me.... I've seen cell standby as high as 47% before.
I can't speak for the drainage overnight. Definitely doesn't sound normal to me, but my phone is usually on the charger overnight (have enough trouble making it through the day with the stock battery).
Have you tried using Watchdog to monitor CPU usage of apps that run in the background? You could set the notification threshold very low and see what it spits out... Good luck!
gbarayah, thanks for the post, that was helpful.
If anyone can help with the inconsistent data speeds, that'd be very helpful.
And any additional info on the battery would be great too. I recently calibrated it, and will post any additional stats.
Damn it, I forgot to try Watchdog. However, I re-calibrated the battery, let it die, charged it up, let it die, charged it up. I followed the instructions to the letter and all that.
It was at 100% when I went to sleep. Woke up 8 hours later, 74%.
Settings > Battery shows nothing high 40% for cell standby and phone idle. Everything else (Facebook, etc.) REALLY low.
Then I went to Spare Parts > Battery Usage, Partial wake usage, everything incredibly low as well..
I will try Watchdog, but could it just be a bad battery? Or maybe should I try a different ROM?
Thanks!
Not sure if 26% drain over 8 hours is normal or not... Maybe someone else can shed some light on that. My phone is usually on the charger overnight.
The only other thing I can think of that would drain the battery is if you have a bad/weak cell signal in your area. I've experienced that with some job sites where my cell signal is very bad and my battery suffers excessive drain from trying to get a better signal or connect to 3G coming from Edge.
On my week old desire Z running virtuous unity sense3.0 rom and streamlined kernal i very rarely see phone idle and radio burning battery lik you say. Radio occasionaly gets high but only wen in bad coverage areas other than thats its ok.
Battery is still rubbish though due to fact even on 2nd lowest brightness setting screen seems to burn 80%-90% battery
Just checked: phone idle:2%
Cell stanby:8%
Screen (lowest setting):70%
Not this isnt a great example as its taken over a short period of havy use but it still reflects the relative proportion of the battery draining elements in question.
Also a question, if you have a live wallpaper set where is its battery drain shown? Screen, or launcher?
Not sure what to say about the high variable speeds.
Sticking to just GSM(2G) rather than AUTO will in some cases increase the signal and battery life at the expense of slower connection speeds. As mentioned when the phone struggles to get signal the battery gets drained alot faster.
Lower the refresh intervals of all the apps to the maximum period of time or a reasonable amount like 12 hours for FB for Sense, HTC Sense and Weather and 4 hours or Never (to make it on-demand) for Facebook.
Setting the Wi-fi sleep policy to "Never when connected" may make it on-demand too - when an app needs to update Wi-fi gets turned on again
If they have "Use wireless networks" checked to allow the clock-weathers mini-widget to update then they should try removing said clock and re-adding it, but search for the city when doing so. It'll provide them with a general outlook for their entire city and not force it to download and update the information for wherever they are whilst out and about. E.g if you were in London and went from Westminster to Peckham, it may update as you pass through each borough.
Live wallpapers and masses of widgets that need to constantly update are nice and everything but they can also drain the battery.
Think of these suggestions as ways to cycle the battery as well as save it.
I can't think of anything else to add.
I'm using Cyanogenmod 7 and it's pretty damn good. What do you think is the best ROM with Gingerbread if it's more lightweight and easier on the battery? (I honestly don't think the ROM accounts for the 25% battery loss but we'll see)
MIUI or mexiDroid for me?
By the way, could it just be a bad battery? I was thinking about picking one of these up:
http://forum.xda-developers.com/showthread.php?t=940263
$8 and people said it's okay.. What do you think?
Thanks, and I JUST calibrated recently, so once again I will leave phone off overnight and report.
-----------------------
As for the network issues, I FIGURED IT OUT!!!
I believe it was the Speedtest app itself that was messed up. Like I said earlier, I don't have live wallpapers (just info) on, and also NO GPS unless using Navigation.
Well, Speedtest was connecting to WICHITA, KANSAS. I AM IN NEW JERSEY. WTH??!!
Anyway, so I'm going to keep GPS (satellites) on, it connects to NJ, and Voila, GREAT SPEEDS!
HSPA about 3.5/1.0 DL/UL
HOORAY! Network problem fixed!!!
Only issue is battery still D:
Honestly, I think it may be a bad battery. Partial wake usage doesn't show any app going nuts.. Every refresh interval is like 4 hours. And I use Advanced Task Killer to kill all apps before going to bed. I downloaded "Watchdog," let's see

Friend has a new Desire Z (bell, unlocked). Using it on AT&T network.
When at a house, and we use WiFI (30Mbps DL, 25Mbps UL), the speeds are VERY inconsistent. With my iPhone 4 using speedtest.net, it shows up as 20/15 each time. (WiFi is a little slower than the modem).
With the Desire Z, we get 15/10 (which is fine/acceptable). Then 3 minutes later we do it, we get 5/2. Without even moving the phone or touching the modem connection (not downloading anything on the computer), the connection just gets slower. Then it might be fast or slow, basically it's a toss-up.
The first time we noticed the issue is because when we are outside, we get HSPA speeds of 2.5/1.0, then randomly decreases to 0.1/0.05. HUGE difference. And VERY inconsistent. He is using a microSIM from iPhone 4, with an adapter, so we figured maybe the SIM card is getting loose at certain points? However, the WiFi is also inconsistent in addition to the HSPA, so it's probably not that.
What should I do? Is this the situation where I have to flash a new radio or something? (Please suggest others if I am wrong).
Thanks!

Also, his battery is kinda weak. The battery health is apparently clean/healthy. He came from an iPhone 4, where he would have 3G, WiFi, and GPS on at night but not actually using them. Wake up, and 3% battery loss, maybe 5. WITHOUT using them, just having them on.
Now, with the Desire Z, we have the WiFi + 3G on, but NOT the GPS. He is losing 20%-25% in 8 hours without even using the phone.
Information about battery shows a high Cell standby (25%) and Phone idle (25%) percentage. When going into Spare Parts > Partial Wake usage, we didn't find anything really fishy. BUT we had rebooted so perhaps some info may have been lossed. Should he just go to sleep tonight and report the Partial Wake Usage statistics again?
We have a feeling it may be some apps refreshing at night.. But he clears all the apps with Advanced Task Manager except for like Facebook (2 hour interval refresh), GMail, and Google Voice.
I highly doubt a 20% battery decrease overnight is normal.. My mom's Atrix only loses about 5% overnight, with the same parameters I gave before.
I thought it may be a bad battery, BUT the phone idle + cell standby are abnormally high.
Thanks!

well... can't be that odd. Mine are
cell standby: 8%
Phone idle 6%
display 51% (highest)
dialer 11%
wifi 10%
....
about conn. speed. I haven't used speedtest yet but downloading speed on the phone is slower than on PC remarkably using the same internet connection

WiFi will always be slower than wired connection, probably about 50% if not more.
Also, what setting do you have your display on and how much would you say you use your phone/have the screen on and how often do you talk (hrs/day)

I have auto brightness but I stay in office and not turn it on much (have to work though ) so the display isn't on much (when i said HIGHEST, it means highest in the list )
I have to phone connected to wifi all day but rarely use it
Mainly use the phone to text and talk less and 1/hr/day
Just try left the phone unused (stand by - airplane mode) for one day, drop about 20% or so
Its seems like its getting a little better.. only lost 10% overnight. Guess its calibrating

My battery was doing well, had about 70+% remaining after about 5-6 hours on battery, then in a one-hour stretch it dropped 30%. I'm running battery doctor, but it really isn't telling me what could have caused that. Even after a half-hour con-call this morning, the battery was still at 80% or so until noon.
It seemed to fall off the cliff when I left the house for about an hour to run some errands. But 30% when you're not doing a lot with it in an hour's time frame seems like an issue.
Anyone have any ideas on how to debug this?

I'd like to know as well. I'm at 33% at 7 hours usage.

Were you using GPS? That's killer on the battery when you combine it with other drains
Also perhaps you ventured into a low signal area, so the phone was straining the battery to connect to a poor signal?
Samething here ... even after a factory reset & disabling a bunch of bloats.
It idles fine @home but really sucks @work ... I lost 30% (last 3hr idling) with the screen off (wifi off too, location is off, greenify running).
Phone barely lasts 2 days (with ~1hr scrren on, 1-call/2-TxtM a day, no emailing ... minimal usage).
One thing I notice... data signal @work is pretty bad (3G) while better @home (LTE).
This is a Verizon phone. My G2 was much much better, same exact setup.
This might sound like the opposite of what is intuitive, but your battery life at work may *increase* if you turn *ON* the wifi.
The reason is that you have poor 3G signal strength. So every time your phone updates anything data related, even just checking that you have an email, the phone burns a lot of battery trying to squeeze data over the poor signal from the cell tower.
But, if you turn on wifi, the phone can check all the data stuff using the wifi, which is far less battery intensive compared to trying to talk to the cell phone tower far away.
So try that, just turn on wifi *particularly* when you are in a poor cell phone reception area. Even though you now have an *extra* radio turned on in the phone, it should greatly help while at work or in any low signal area that has wifi available.
when did you get the phone? you have to do a few full charges and disable some Google bloat for the battery to last. and remove batter doctor. don't use apps like those task killers that keep themselves in the background like avast security. i just use lookout since it doesn't overly do it's job like avast.
What carrier are you on? If its T-Mobile, then its probably the My T-Mobile app. Drained my phone like crazy, T-Mobile also knows its an issue, but haven't said anything on fixing it.
Just uncheck all the boxes in the settings and it should stop, if not try the debloater tool.

This will still drain it heavily even on wifi. It will continue to struggle to get good bars and will do what it takes in order to achieve good reception.
At work I always have wifi on and my drain is very high.
A weekend at home and I easily got SOT of 4 hrs+.
Work day, I struggle to get SOT of 2 hrs+
Very interesting approach, and it seems to work. I tried this overnight, and the falloff didn't seem nearly as great as when the wi-fi setting is off.
Many thanks.
I'm on verizon and when my phone switches to 3G it gets super hot upper middle area of the screen and the battery drain is outrageous. I have to disable data otherwise it would probably burst into flames. My previous unit did not have these problems. Wish I would have kept it.
