Normally I leave home with a full charge and come back 10 hrs later with about 15% battery remaining. I won’t break down my type of usage but it’s a general mix of voice and data. The phone is in my hand, in use, about 1hr and 30min per day with the screen on about 45min.
Today I ended my day using the phone about 1 extra hour (incl. 30 min Bluetooth phone call) and had 48% battery remaining. On a normal day I would have never even had gotten to the 30min phone call before it was dead.
So, if you do the math, the battery life today was roughly double of what it has been for the past 2 weeks.
I made one small change ... I turned off the GPS. Yes, I know, the GPS is only supposed to be running if a program that requires it is also running. I think that is false. In settings, locations the only feature I’ve ever had turned on was the GPS. I started thinking yesterday how amazingly, unbelievably really, quick that Google Maps set my exact location. I have 2 HTC phones with built in GPS and have had 2 Garmin GPS units, using an external GPS antenna, of which not one of those would acquire a satellite lock in less than 30 seconds, usually 45 to 60.
Now, flame me if you like but I’m convinced, after today, that the GPS is always acquiring satellites even when the icon isn’t present.
I downloaded GPS Test from the market, closed ALL programs with ATK, ran GPS Test and as soon as the screen appeared, 2 seconds, 4 satellites were already locked. It can’t be that good.
Try it ... won’t cost you anything.
BTW, it would be nice to get some feedback from someone that gives it a try. I’d like to know if this truly worked or it was just a fantastic coincidence.
Thanks
Nope, I agree completely. I've kept GPS off unless I absolutely need it and my battery life is great.

Glas to hear someone echo the thought. I may actually start to enjoy this X10 afterall
With GPS off, WIFI off and BT on about 2h/day i get 2 days juice
Problem is, i'm in wifi range 24h/day and i don't have a data plan so, wifi is on most of the time => about 12h juice.
GPS and WIFI are draining battery pretty fast.
Made a huge improvement for me too well done for spotting this

do you mean specifically turning gps off under settings, location? or all location services including location by network?
I am using the R2BA020 firmware.
I make approx 2hr voice call per day.
I left the wifi ON, but remove the wifi detection notification
I left the GPS ON, it should be only be activated via GPS apps.
I turn OFF the BT when I am not in the car.
So far, after weeks, on the average, I still get 2 days of juice at least.
oops! miss out the text...
I do only about 20-30 text per day.
And do quite a fair bit of FB and Twit daily...

I'm using 023 and wouldn't get half of that time without turning off the GPS.
I'm not sure if my GPS isn't sleeping the way it should or not but unless I turn it off it always seems to be active.
It's not a big problem for me since GPS isn't a feature that I need too often and it's pretty easy to activate from the widget if I do want to use it.
Strange as it may be this is the change that made the single biggest difference for my battery life.
Last night I installed (reinstalled) SetCPU and set up some profiles I read about that look like they make sense. One of the profiles that caps the processor at 338mhz when the screen is off but runs it full tilt when the screen is on seems to be pretty logical. My previous complaint about SetCPU was when I had it set to near 600mhz the screen performance seemed really slow. Now it only caps the processor when the screen is off so if checking email in the background takes an extra microsecond but helps battery life I'll be happy

I can't really comment on WiFi usage since I only use it once in a while to run SwiFTP but GPS radios are a big battery drain, have been on every GPS device I've ever owned.
Today with the GPS off and SetCPU setup better (from last night) I plan on giving the X10 some heavy use today and see how it does.

Glad it helped you.
just for your information. if you use the widget for wifi,silent,gps,BT which was included by SE you will notice that this widget has bugs. for example it shows that gps is off while it is on in the settings. same with wifi.
dont use this widget. take a widget for example from curvefish. these work properly.
I'll check out that widget problem, thanks.

Hi, I've got an unrooted R2BA020.. I've done a test this morning. I use wifi all the time at home and today have used the stock widget and quick profiles to enable wifi, bluetooth, GPS, and 3g. They've all been on for 6 hours, have actively used wifi for about an hour or so.
I'm now down to 90%, from 100%.. 10% in 6 hours.. More than happy with that.

I'll try it this weekend.
Well, I finished a 10 hour day with moderate usage, maybe 1.5hrs of screen time, 45 min phone calls, 3G data, no WiFi and the GPS turned off all day with 48% remaining.
That, for me, is a big improvement.
Since it's still not as much as I would like (I find myself holding back from using the device more) I've ordered a 2600 mAh Cameron Sino battery from eBay. I know, the battery is made in HK but what the hell ... the phone is made in China
I've read mixed reviews on the CS battery but most lean towards good.
I have encountered a problem (or not!) that the battery seems to drain real fast (8-10% per hour) when the phone is in standby mode with WIFI on and the only app running in the background is Ebuddy. I don't know if this is a problem or not because on my old Blackberry Bold, even if you let a chatting app such as Jivetalk running in the background with WIFI or 3G on, the batterry doesn't drain that much, in fact it uses just a bit more battery than just standby. My phone is not rooted, and if I continuously use the phone for chatting, surfing and listening for the music, the battery seems to be find though, I get around 6 hours until the battery is dead. Any help would be awesome, thank you very much for your help
Try switching off your GPS. I did and now my battery is sweet. I only switch on the GPS when I need it, i.e. maps, weather, you get the message...
What widgets do you have on your home screen? I've had problems before with some of the active widgets preventing the phone from sleeping.. I generally get 2-3 % per hour when in standby.
Now at 88% after 6 hours..
I have wifi on 3g on and gps on and bluetooth on.. So they're all sleeping just fine.

Actually i dont have many widgets running in the background, I only use 3 home screens, the widgets I have are Beautiful Widgets, Calendar, Battery Life and I have Juice Defender running in the background full time. The problem is, standby mode without either WIFI and 3G is OK but with any of them, the battery starts draining real quick
you should be able to set wifi to sleep when phone display is inactive. 3g will always use more juice than 2g but how much more seems to depend on your location and 3g availability/strength. I get about 1 day use with 3g turned on and 2 and a half days with only 2g enabled.
It would be really nice if the phone could switch back to 2g when sleeping but its not possible to do because you cant control the 2g/3g directly from apps. The best that apps can do is display the standard android settings page.
Ahah... Juice defender... I've had problems with that preventing my phone from sleeping.. Suggest you do what I did and de install it.. My phone lasts a lot longer without it..
Also, if that still doesn't work try removing beautiful widgets, I've not heard of problems with that one but some of the weather widgets also prevent the phone from sleeping.

Thank you very much guys, I will try to uninstall Juice Defender to see how it goes. I did mention 1 thing in case you forget, I had Ebuddy running in the background, facebook and twitter update every 1 hour or so, but even that.the battery still seems to drain too fast, even when nothing using connect to the internet

Hi - Couple of things.. .. 1. Did you disable JD before you uninstalled it - read somewhere that this is the best way.. and 2. Have you restarted the phone to clear JD from Memory?
Which version of the firmare are you on? The older ones 014 and 016 weren't as good at sleeping..
Task Killers also tend to cause problems (@GT Blackice) They will stop things that need to be in memory and so the phone will restart them.. I've found it better without.. Phone runs smoother and battery lasts longer. (Although one or two others believe that they help; I think that this is because they're killing dodgy apps which aren't sleeping properly when not active.)..
Yes i disabled JD before uninstall it and did a clean reset even with taking out the battery. I'm on firmware 023, I think its the latest one for my phone. It's so bad if the battery cannot last any longer with WIFI on, anyways thank you a lot though

Disable APN(3g and 2g, there is a widget for this) while you're not using it and battery last significantly longer. If you need internet for E-mail push or some other apps(timescape) then use 2g(as was reccomended above) and be happy if it lasts for 2 days. I've also discovered that using wifi instead of APN uses less power.
That's really odd. I'm on 023 too and mine is fine.. The only other thing I can think of.. Possibly... I've stopped using timescape...

How can u disable Moxier Mail if you dont use startuqap manager. Cuz this app was the real drainer. And how do you disable Timescape? Did you use any WIFI at all during the last 16 hours? I even uninstalled the weather widget and the prob stayed there, nothing changed. Arghhhhh...
Sent from my X10i using XDA App
I thought moxier was a problem too, but in the end turns out not to be.. As long as you've not configured it, it just sits in the background not doing anything. Haven't disabled timescape.. Just removed the widget and set the update frequency to never, then stopped using it.
Wifi has been on and active quite a lot. Used xda and internet a fair bit on it yesterday.

If you have a rogue app that is causing the phone to not sleep properly would it not show up under the battery status in settings?
If you see Cell standby, Phone Idle and Display at the top of your list in the battery usage and that accounts for around 90% or more then your phone is probably working as expected. If the display percentage is too high you can probably reduce the display brightness to save battery other than that the only thing you can do to affect the battery life is to turn reduce refresh times for apps which update automatically, turn off APN or switch back to 2g.
Thanks everyone for your advices. Anyways, the prob doesnt seem to fixed though, maybe its because of my phone.

Hi.. How do you know that moxier was draining the battery?

there is always a chance your battery is damaged. Get a battery graphing application and see how it drains over time. One of my friends had a phone with a bad battery - one of the cells was clearly damaged and unable to retain charge properly and it was easily visible when watching the battery drain over time
at work today i guess i had a bad signal and i noticed i lost over 20% in less than 8 hours. whats the cause of this and is there a fix? i also notice the phone runs like **** on a low signal, very sluggish even when overclocked.
More power is bein pumped into the radio to keep the signal strong(er). Airplane mode is your friend. As for being slow, I don't know why but I also experience slowness in low-signal areas.

must be an android thing because i never had this happen with winmo or my palm pre.
Turn off 'Background Syncing' in Accounts & Sync settings. That will greatly improve both your battery life and phone slowness in low-signal areas. I have terrible signal in my work building too (would almost completely drain my battery in an 8-hour day), and ever since I started turning off Background Sync while at work, my phone only drops to around 50% in a work day.
I really think it's more the syncing that sucks the battery down in low-signal areas, not the radio having to broadcast stronger.
I have bad signal strength at my house. I also have a Airave to make up for this however since it does not provide 3g my battery will drop like mad when I am home.
The fix for this in my case is to turn off my mobile network when I get home that way I can still receive calls and texts but it basically tells the phone to quit looking for 3g signal and sticks to just the basics.
I then use my wifi while at home to get on the market or have my gmail and other apps sync with the phone.
Hope that helps you out and you find a solution that works for you.
I noticed MUCH moreso on CM6 vs. Fresh 2.3.3 what a significantly negative impact having background data enabled in a low signal area can have on the phone. My workplace is a consistently terrible cell area and since switching to CM6, I have been not only plagued with terrible battery life (like 10-15% per hour with minimal usage!), but the phone was running like absolute poo.
Today I checked to be sure and to my surprise, background data WAS enabled! I promptly turned that off and the phone returned to it's former CM6 glory and battery life returned to non-workplace goodness.
I have a bad signal at work, so I force it to roaming. It saves my battery and my phone is more reliable. Just be careful not to use too many minutes or too much data.

How do you set it to roam? Is this a setting or is there a code i can type in whenever I want it to only look to roam, then another when i want it to go back to regular, or even if i only want it to look for 1X or only look for 3G? One of the client sites i regularly travel to has great roaming 1X speeds once i can get it to switch to that but it must also have a weak roaming 3g tower somewhere because its always on 3g with one to zero bars.
I'm on Fresh though i'm apparently going to have to look into CM6 in the near future. I love this place.

You have a few options...
1. You are running Fresh on your Hero? Use the modded phone.apk from here: http://forum.xda-developers.com/showthread.php?t=745092
2. Use the PRL hack...you'll have to search for it, although I think the link is in the thread that I linked above
3. Download the app "Roam Control". Disclaimer, I am the dev, and yes it costs money.
4. Flash CM6.

It automatically kills your data when signal is low. You tell it what signal strength turns it off. Does wonders

No..not really. I had several TP2 windoze phones since May of this year and went back to my Hero. The battery life on the RC1 build when you follow what has been said here,will give you way more life than any of the phones I have ever had.I was lucky to see 4 hours of life even with little usage with the TP2's. While my CDMA Hero does drop to 80% with everything turned on in 7 hours,it slows down considerably after that. Just with mild web crawling and 20 minutes of talk time it took well over 60 hours to drain completely last weekend after resetting the battery stats on mine with everything turned off. I actually had to use it non stop for 4 hours to drain the thing so it would shut off and be drained. Any phone I have ever owned has always done better after letting them drain completely and then charging them to 100% a few times. We have 4 of them in our home,and mine last longer than any of the others..the other 3 are stock 2.1.6 roms.

Why are people complaining about losing a measly, small 20 percent of battery in 8 hours? I'd understand if it was 35 percent or more, but seriously? you're complaining becuase your battery can last 40 hours? Wow...
CM6 RC1 with collin_ph battery tweak rules the world.
what i do to save my battery i change the settings on my advance task killer Menu>settings>Auto kill level(crazy)then also change Auto kill frequency(when screen off) and that really seems to help me
You could also look in to JuiceDefender. It shuts off 3g when screen is locked, turns it back on for either 1 min every 15 mins or 2 mins every 30 to sync.

not everyone runs the froyo rom. at least i won't until a sense port comes out. and yes when the phone has a low signal it runs like absolute ****.
I'm having this problem also on CM6. Unplugged my phone this morning, full charge. Went to the gym at 11:30 and worked out for an hour and a half. There is no signal in my gym. The phone was completely dead when I got back to my desk. So basically the 80% battery drained in 1.5 hours (assuming I lost 20% between 7am and 11:30 when I went to the gym) It was not nearly this bad on the stock ROM. I just insggtalled collin_ph but I doubt that will help in this scenario. I might just have to remember to put it in airplane mode before going to the gym.
My bigger worry is when I'm out riding my road bike in the country. If I'm in the middle of nowhere, the battery will drain FAST... and thats the place I'll likely need to call someone in an emergency.
In my opinion there are key steps to insure a good battery life I perform this process every time I turn my phone on for daily use
First in settings/wireless/mobile networks I turn off data also roam and I change the signal to home only then in account and sync I turn off automatic sync and back ground data also i make sure that wireless is off as well then I turn my attention to applications and I clear data and force close any running program I'm not using for example gmail e mail browser Google search blue tooth I only force close apks that I know wont affect the system and how it runs also I should mention that this is done after I had calibrated my battery also I in spare parts I choose to make my end button put my phone to sleep these two steps are only done once now back to the process I run the over clock widget with dead3nce 9/14 stable kernel but also with every stable release he has put out I set the feq to 710 Max and 710 min and diff feq when screen off with 384 Max and 245 min this setup gives me high performance and long battery life I get 14 plus hrs with heavy use before ill hit 50% so u can imagine with moderate use will b or even standby time so I basically kill my phone if I'm not using it its in what I think is its lowest power state that I can get it at but its still on and ready so wen Im ready to use it I activate it and turn on what I need when I'm done I kill it again short of turning it off just thought I put this out in case it helps also I'm running cm6 rc1 and the 8/22 nightly I switch back and forth because of themes but the process is the same and so are my results so hope this helps good luck

It's 3G. Turn off your Mobile data when you going to be in an area with a bad signal for a long time.
As someone else said the collin_ph battery tweak works wonders too.
thiis thing dies on me really quick, at home not as bad when I'm on wifi, but i left this morning from my house, and by the time I got to work 45 minutes later i'm at like 90% and i've done nothing on the phone, not a thing, no text, no voice calls. time without signal is 0.
then of course I get to work and time without signal jumps to like 22%, but still, my blackberry didn't go dead in half a day. i'm running the mixup undervolted kernal and the epic experience rom.
I do run gps and normal phone settings but turning them off is really not an option, especially for my wife that just needs a phone that works and isn't dead before she is out of work, and she doesn't even use the phone.
am I doing something wrong or is the battery life really this crappy?
and it was worse before the new kernal on DI18, and way worse before that.
i use the same set up i got 10 hours under pretty use
try turning gps off at work
So what are you leaving on? 4g? Gps? WiFi? I found that using black wallpaper helps.
wifi and gps are always on, it seems its TWS that is killing it. at like 22% right now. battery is down to 83% right now 2 hours off charger. no voice calls or text calls.
If you are getting a tws of 50% then put your phone into airplane mode for about 10 seconds and then switch it back, you will see a dramatic decease in tws

Here's a few things you can do ...
1) If you have Sprint service in most places, turn off roaming (Settings, Call settings, System select, Sprint). This will disable roaming period so that all roaming services are disabled (i.e. you won't ever see the data roaming guard).
2) Download JuiceDefender beta (this turns off all data, i.e. Wifi / 3G, whenever your phone's screen is off, if you purchase UltimateJuice with it, you can schedule it however you want, and you can choose to allow some apps to always allow data to go through). This saves me a LOT of battery since my screen is usually off.
3) Try the TWS hack mentioned in the earlier post, it should be fixed in DI18, but some people are still seeing high numbers there.
4) If you're rooted, get an app like Autostarts and disable the DRM service from ever running. This was found to be a battery killer.
The biggest battery drainer of them all is the GPS, and then 3G. If you can minimize your uses with those, you will maximize battery life. Also, use Wifi in areas that have it because Wifi hardly drains battery at all compared to 3G. I haven't seen any kernel really that gets much more battery life than stock, so doing these things will help. I love the Epic, but the battery life is a real downer for me too. I've gotten a full day's use (medium use) at times, while some days it hardly lasts at all.
Yes do the airplane mode trick and turn off gps if you are not using it and DO NOT USE JUICE DEFENDER i get 45 hours battery life without it. that app runs constantly in the background and uses more battery. Juice defender is for lazy people that dont know how to find these data and sync settings that are already on the phone or you can download an app that will let you toggle whatever setting you need. Set emails to sync once an hour and if it is really a priority then go into the email account and push refresh.
If you are really getting 45 hours of battery while actually using your phone then will you please share all of the settings that you have that give you this kind of battery life

I wondered if that would do anything. Considering how AMOLED works, dark themes and wallpapers *should* help battery life similar to reducing brightness.
Auto-Sync does some mean damage if your settings are too frequent, too. Try not to use Facebook/Twitter/Myspace integration, if possible, or disable them from syncing automatically, and sync them yourself when you feel the need.
Okay I don't know exactly what I did/didn't do but my battery problem seems to be greatly improved. Lets start with my details. Before 2 days ago. No matter what my use my battery drain would be approx 6-8% an hour. If I took my phone off the charger at 11am by 4pm I would be around 60%. GPS/4g/wifi off. Screen brightness set to lowest. tws not too bad. Using both the tws trick and drm stopped. Usually 2 or 3 phone calls 5-10 texts 5-10 minutes of browsing. I had a task killer installed but never used it to kill tasks just as an app switcher. Even after the di18 update no major difference. So the other day I downloaded an app called system panel. Another task manager. I deleted the task killer widget on my home page but no the app. The first day I took my phone off the charger used it for about an hour then put it back on the charger for about 15 minutes. When I took it off the charger it was at 96%. I opened system panel and killed all apps (necessary services/apps restarted immediately) did tws trick and drm kill. Same use as always after 8 hours my battery was at 80% a 16% drop. That's 2% an hour. The next day I deleted my task killer and over the same period of time I went from 96% to 83% (13% lose over 8 hrs) Only a little over 1% lose an hour. The only difference that I am aware of was the deletion of the task killer widget and then the app completely.

If you are really getting 45 hours of battery while actually using your phone then will you please share all of the settings that you have that give you this kind of battery life

Ditto, I'd like to hear what you're doing too ... even when I do not TOUCH the phone, I cannot get 45 hours. I think you're being a bit optimistic here.
Lmao No. Since di18 it has been great. I use my phone for a lot of stuff too. I have a live wall paper and rss feeds that update. email is set to once an hour. Now dont get me wrong if i play a game then it will suck my battery pretty good like 5% for ten minutes. i have a widget for sync settings. im rooted with ALL SPRINT apps removed i think thats the biggest thing. dont leave gps or other on if you are not using it. i do not have drm removed. i use full brightness. i talk a few times a day and dozens of text and web surfing. no juice defender or task killers. The object for me was to not have any unneccessary stuff run when it doesnt need to. so the phone is set to come alive when the screen is on not off. Check ALL APP and WIDGET SETTINGS FOR HOW OFTEN THEY UPDATE. I DO MEAN ALL. GO THROUGH EVERY APP AND CHECK THEIR SETTINGS ALSO the biggest drain is make sure you sign out gtalk or it will just constantly run. I shoulda posted my screen shot of battery life earlier sorry i will as soon as it reads 1d21h again. prolly tomorrow afternoon.... Rooted,cwm,galaxy rom and kernel, blue minimalism theme

Yes do the airplane mode trick and turn off gps if you are not using it and DO NOT USE JUICE DEFENDER i get 45 hours battery life without it. that app runs constantly in the background and uses more battery. Juice defender is for lazy people that dont know how to find these data and sync settings that are already on the phone or you can download an app that will let you toggle whatever setting you need. Set emails to sync once an hour and if it is really a priority then go into the email account and push refresh.

i do the airplane trick, problem is it seems,when im on wifi, the life is great, battery is perfect, as soon as you go to 3g, it goes to crap, plus the service where I work is spotty as well. I don't know what to do, seriously I can't go through 2 years of great cell service that I can't use because the battery is dead. I mean if I could get through 10 hours it wouldn't be bad, but as it is now, i'm lucky to squeak through about 8 hours. and I have the mixup kernal that is undervolted and supposedly already messing around with the cpu. usually on 3g, no matter where I am pretty much I"m at like 10-20% TWS.
tws is 50% for me. just stop the data with sync settings then it has no reason to draw more. my house and school have terrible service. you are only losing battery life due to data that is going really slow and it takes way more battery to accomplish. i keep wifi on all nite at my house but my sync settings are off. i do this so its not searching for 3g because i have an airrave and wifi. i used the di07 mixup and was not happy with it. galaxy roms have been the least buggy and very stable with the best battery life. That might be my opinion but also genius dog doesnt have an epic yet so i cant trust his stuff when he cant see the impacts with the kernels he is making. but he does know code i will tell you that.

Holy crap 8 hour battery life is really bad.
Do you have any apps syncing? A weak signal with an app syncing can have a devastating effect on the battery life.
In my school building I get 0-1 signal bars and once I use the stock email app to sync my email every hour with 3G on my battery life is probably a third as good.
How?

Inside my building where I get a weak signal I turn off 3G and use the wifi to sync my apps regularly. I get a good wifi signal there.
If I can't get a good 3G signal in the building than there's not much I can do to my phone to make the 3G signal better (I think that's the cause for the battery drain).
So my epic seems to like to reset its 3g radio randomly. It does it more often when on a charger, but also does it when on battery. Its the same thing that happens when you update PRL, you get the little double beep and the radio is back on again. Anyone have any idea if this could be a software thing, or is it time to go exchange at the sprint store?
Isn't this the problem that's addressed by the "Airplane Mode" fix? (fyi -- toggle AM off and then back on after boot and the problem you describe won't happen)
Ahhhh. I thought that was just about tws. I haven't had an issue with tws so haven't been bothering with it. I'll give it a shot.

I've noticed th same thing it seems to happen most often when I'm on the move, driving, walking, etc. I notice it most because it interupts audio. I don't want to shutdown my phone right now but ill try this later

This happened to me as well. Around the clock, I'd get a double beep as the 3G turned off and flicked back on. It started after I rooted and installed Wifi Tether. I also noticed that the Wifi was constantly scanning for networks, which was causing some seriously terrible battery usage.
I reset the phone to factory stock and the problem went away. Rooted again, still good, installed Juice Defender and Juice Plotter, and everything has been great since.
When I get a chance or have the need, I'll reinstall the Wifi Tether (the "pre-10" build was the one that worked for me a couple of weeks ago) and see if that was what was causing it. I think that some setting on Wifi Tether was constantly turning the 3G off and looking for a WiFi network to plug into, then reinitializing the 3G data connection.
Anyhow, since the wipe and re-installation of droid apps that I know work well with my phone, the radio beeps have been completely absent and battery life is now 36-48hrs per charge, depending on how much I use. Juice Plotter has my battery going down 10% over 8 hours of standby-only use, meaning I could get as much as 80+hrs of standby time, which makes me really happy.
So: I'd suggest backing up your contacts and data, doing the factory reinstall, then slowly reinstalling a few apps at a time and seeing if it's one of them that's messing with the radio. You might also want to grab a battery charting app and see if one of your apps saps your battery super quick, because I do believe it's the on/off/on/off toggling that chugs through the battery.
