I have a buddy with a droid x that gets RIDICULOUS battery life. What is it that causes such a difference in endurance? I mean most of the other specs basically match up... Is it htc related? Can I get "droid-like" battery life somehow? I'm on fresh 3.3 with netarchy 4.1.9.1 bfs

I havent played much with the DroidX but from what I have read it has a power profile managment on it much like a laptop . I believe that is the part Motorola put in the phone . Profiles like LONGER BATTERY LIFE , or MORE PERFORMANCE . Something Im kinda surprised the EVO wasnt given but I make it thorugh the day on one charge
Are you rooted?

Please keep in mind the apps you downloaded and the widgets you have set-up on your screens. Some apps require to be run in the background eventhough they are NOT used by you at the time, such as Google Talk, Qik, Fring, pedometer, and anything that needs to be "ON"...thats one of the culprit on battery drain you might want to look into.
Having one widget per homescreen is ideal, in my opinion..and learned that by having multiple widgets in one screen, is another culprit in battery drain due to it requiring to work upfront, for example, Facebook widget needs to be on constantly and updated for as long as that widget is there, regardless if you touched/used it or not.
Now, for the MOST OBVIOUS part...turning off GPS, WiFi, 4G, and bs when you DON'T need them, by following hot sexy COMMON SENSE, you should get AT LEAST 3 hours more on your battery. Pure sexy common sense LOL ;-)

Greetings,
I couldn't agree more with all the things you noted in your reply.
I rooted mine, and deleted many apps I don't use, but insisted on starting up
even if I had already killed them in the manage applications section.
But I was amazed at how short the life was in spite of having done that. I quickly
discovered (as you noted) that keeping 4G on, drains the batt.
In fact, for me anyway, it really drains the batt!
Just thought I'd mention it, because it was really surprising to me just how bad
an affect on the battery 4G was - bummer.
--Chris
Mine usually gets between 36-55 hours on a charge (record is 58 so far) with about 3-5 hours of "use" on the stock battery. I don't use it to play games or watch movies, just phone, internet, email, etc - widgets all over the place. Gmail push is always on as well. In fact, I unplugged it last at 10:50pm on the 28th (34 hours ago) and I'm at 48% still.
The biggest thing I've found is download setCPU and adjust the CPU frequency to 245 MHz when the screen is off. That saves a lot. Other then that I keep it at 998 MHz (max speed) all other times. I am playing around with tasker and turning airplane mode on while I sleep, but that seems to have a minimal effect, saving around 2% over 8 hours. I use tasker to turn GPS off unless I'm using one of my GPS-enabled programs, although that doesn't seem to do much either.
I'm running just a basic sense rom with a stock kernel, nothing special. rooted with clockworkmod and that's all I've done rom/kernel-wise.
If you actually use your phone a lot I'm not sure there's much you can do besides get a bigger battery. If you just use it mostly as a phone and less as a PMP or gaming device you should be able to get some nice results.
EDIT: Oh yea, and don't use a task killer (I don't). From what I've read those can actually cause the phone to consume MORE power as services are being killed and opened constantly. Android is very good about leaving tasks open in the background without them consuming power. Opening and closing them constantly is another story.
I wish I could figure this out too. I've been switching between a ton of kernels and roms and can't seem to find anything with good battery life. My phones been unplugged for about 2 1/2 hours and I'm at 53% battery life. No widgets running and just average usage.
Running virusrom and kings #9 and a lot of other roms and battery life is a joke.

So far, the best battery combo I've found is fresh 3.2 with it's stock rom and I returned to it last night. Some say 3.3 is as good or better but I can't seem to get those same results...
But my real question is, why is the droid able to get such great life?

What I have found to help most of all is to NOT use the Mail app - it drains the battery like crazy, especially if you are popping several accounts. Instead, use the gmail client and set it up to pop your other accounts, and push them to you. This literally trippled my battery life. And it is way faster than the 15 minute intervals that the mail app gives you. Give it a shot, you will be pleasantly surprised.
Do you use a spare battery and if so, is it the same brand and capacity or different?
If it's the same brand and capacity, what's your experience on how Android handles it?
If it's different brands and capacity, what's your experience on how Android handles it?
In my personal experience, Android is very poor at "handling" different brand/capacity batteries. For example, one of the batteries will perform very poorly (like at only 20% of its rated capacity).
Never had problems like these with Windows Mobile. Not that any of us would want to go back to Windows mobile, but a major advantage of Android phones is the ability to swap batteries, but this doesn't seem to work as well as it should.
Hopefully, maybe I'm the only one experiencing this and everyone else's phones work "normally" as we'd expect.
I've got two eBay/Chinese 3500 mAh batteries. I only bring the second with me to work if it's going to be a >12hr shift.
I've also got five eBay/Chinese 1500 mAh batteries (4 + the stock battery). They all work fine, and the only time I'll use them instead of the bigger ones is if I'm getting tired of the 3500's additional size.
But, as far as I can tell, they all work as expected, even after going through the laundry once or twice.
Stock and OEM extended batteries from Sprint/HTC. One of each. They do quite well. Usually extended battery is enough to get e through the day. Stream lots of music through Plantronics Pro bluetooth headset during the day.
I have a seidio 3500 and a hong kong 3500, both seem to work about the same, I also have 2 2000's from china that are the same size as stock but do last a bit longer, maybe a couple hours more than stock in similar usage situations. 3500 seems to be fine for a complete day of medium/ some heavy usage
That's good! What ROMs do you guys use? Maybe it's my ROM that has problems.

My ROM and Kernel info is in my signature. My battery issues were usually an issue with kernel. Tried Virus ROM AirBorne and ziggy 11\13 kernel which was great, but currently am using what is in sig.
Also found 4g to be running and doing a continuous scan (even though I dont have 4g here) through logcat so I made some changes there too.
Seems some 4g widgets can activate 4g, on startup or otherwise, and cause it to scan for 4g when not in use or even after you turn it off.
If you toggle on 4g and toggle it off it may not be enough. Reboot phone and it should really be off then (verify through logcat). Also make sure 4g doesn't activate itself on startup or reboot, unless you live in a 4g area and want that of course.
stock battery and two 1500mAH china battery..
I don't like extended battery.. makes my EVO looks fat..

I'm getting ridiculous battery life as it is on my rom. I can go two days on heavy usage, 3 on medium. I always play music off my phone when driving, at least an hour on the phone, and 200 texts a day. Throw in craigslist, engadget, and nfl apps and about an hour of games a day too.
Battery life on 2.1 was actually better though, with fflokes old kernel on 2.1 I was getting 80+ hours/charge. Haven't fully tested as the newest fresh rom has been the best battery life since then, but I'd guess it could top that now.
Twitter, fb, google, weather, and news syncs on, never turn 3G off, barely use 4G or wifi. Only bt for long phone calls.
I don't notice how crappy my battery life is until I'm on the etchings battery. They only last about 4-6 hours for me. Got autostarts, juice defender and most of my radios off..i just don't know, any suggestions?

how many batteries do you have?
you many have to recalibrate your battery stats.
if you have 2 batteries and an external charger:
charge the OEM battery in the external charger, those usually charge SLOWER than the AC adapter which is better for the battery
when the OEM is fully charged, turn off the phone and insert the OEM battery
boot into recovery and WIPE your battery stats
reboot the phone
depending on your ROM and kernel, you should easily get at least 2 days run time per charge.
After this, don't use a 2nd battery anymore, Android sucks at recalibrating the battery stats every time you swap batteries. Really a shame.

Turn off Mobile Data always on, go to Google Talk/settings, and uncheck automatically login, then log out.
Get rid of people/facebook/twitter widgets which constantly download pictures from your thousands of facebook friends/followees, or make those widget do updates at human intervals, like maybe once every 30min-1 hour.
I dontt have any facebook widgets out. I didn't even know my google talk was always signed in like that. mobile always on is off. After doing the battery stats wipe and using the OEM battery I am already at 93%. Maybe I should get a rom? I have juice defender running at 1.5x(maybe it's a problem?) And setcpu also.

I found that having set cpu and juice defender etc. didn't improve my battery life very significantly. Or I should say, significantly enough to justify slowing down the device on purpose to save battery life.
A good kernel (like netarchy's 4.2.1 cfs havs more) will help quite a bit with idle battery consumption, and somewhat with the active usage consumption. A rom would probably not change it much, but try something like Virusrom Airbourne (I had excellent battery life results with that one).
In the end however, you won't be able to get better results than approximately this:
1) ~1% battery drop in 1 hour of idle (screen off, 3g on) time.
2) ~0.5% battery drop in 1 minute of active usage time.
That's the hardware limit - a fully charged battery will afford about 100 hours of standby, or about 200 minutes of active usage time (less with cpu intensive games, which will heat and drain the battery more, of course).
There's one big battery drainer I haven't mentioned outside normal usage.
If your cellular signal is bad, the cellular radio tends to drain the battery in a BIG way.
In my office, I have pretty bad cellular reception. I actually have to force roaming and connect to a different provider if I want to save battery.
(In fact, I think I just dropped 8% in about an hour of basically standby, because the signal is 0-1 bar here).
You made a lot of nice points there. I'm in the basement so depending on the spot I'm in the 3g AND the 2g vary. By my bed is the worst but my wifi isn't cooperating with my phone. Always timing out yet keeping the connection. My battery was better with wifi when it worked cause it's in the same room. I'm thinking of uninstalling setcpu first cause juice defender increases it's percentage when battery sucking app is uninstalled and vice versa. I am thinking about flashing a rom but I hear so many problems with these roms so not sure.

I get about 2-3 days of run time after using this method. I used to have 2 batteries and swap but not anymore. If you want to use more than 1 battery, then make sure that both are the SAME BRAND and the SAME CAPACITY (mah).
Can we petition Android to automatically wipe battery stats every time the battery cover is removed? Or, even after reboot would be good.
Quite a few people in this thread getting 1, 2, 2+ days of run time:

LIES!! Battery stats don't get wiped, recalibrated, or other whimsical notions you have when swapping batteries.
I have three extended batteries, swap them out every 2 days and I don't get worse battery life with one battery over the other.
If your battery stats are being "recalibrated" when you swap your battery there is something wrong and it has nothing to do with android.
Note to mods: I copy pasted this question from another forum to get different answers. I am the same person, please be lenient.
Hello, I would like to improve my Evo's battery, because a few texts, a minute in the browser, and just scrolling through my email brings me down to 60-ish percent battery.
I'm running the latest MIUI with Tiamat 4.0.1 or something like that. I am also running JuiceDefender Ultimate.
My screen brightness is also at a constant low, too. I should have done more research on this phone, as I'm stuck with it for another 1.5 years. It sucks. :/
My friend's iPhone lasts for so much longer, it doesn't have a larger screen, but still..
What can I do to improve my battery?

You can undervolt with vipermod
Sent from my PC36100 using XDA App
I've never used MIUI so I don't know what options you have for kernels, I imagine all AOSP Gingerbread kernels, but if I were you in would try out different kernels, even a different version of Tiamat could help. You can also try calibrating your battery.
If none of that helps, try switching roms.

Won't ViperMOD hurt my battery?
There's always the obvious. Turn off what you don't need - GPS, 3G, wifi, Bluetooth, etc. I assume that Juice Defender helps with that but I've never used it. If you can use wifi instead of 3g then you should, it saves a lot of battery. If you're in a low coverage area, that will kill your battery as well. Going through your installed apps and uninstalling the ones you don't use will help as well. Back them up with TB first if you want to save their data or easily reinstall them later. Check your sync settings, if you have social networking apps set to sync every few minutes then that's also going to chew through your battery. Using push notifications instead of regular syncing can help - try FriendCaster if you use Facebook.
I'm also running MIUI with Tiamat 4.1.0 SBC. If you're not using SBC then you may want to try it out, it can help with your battery life. I ultimately gave up on sacrificing functionality for battery life. Instead I bought 3 extra 1500 mah batteries which came with an external charger. All together it was $11 on Ebay with free shipping, took about two weeks to get here. If you decide to go that route, you can just run the battery down and put in a new one... your friend's iPhone can't do that
I still use an SBC kernel even though my battery isn't usually charged through my phone. If I forget to charge my batteries or something, I'll sometimes put the phone on the charger when it gets down to 80-90% and charge it back up. When I do that the battery lasts all day and I don't have to switch batteries.
You can also buy an extended battery, but I didn't want a fat phone. I get just as much juice - if not more - from my cheap 1500s.

I'd recommend looking up Car-O-Dope's tweaks, it's helped me be able to run the governor at 128mhz-652mhz and not sacrifice any performance. This has saved my battery life. This guide will have you download rom toolbox and system tuner, and in system tuner you can undervolt your battery as well without having to run the Vipermod scripts. In rom toolbox I changed the wifi scan interval to the max amount of time possible, and changed the wifi sleep policy to never. I leave wifi on at all times, keeping the 3g off. My battery has never been better.

I seem to be having battery issues as of late. Been running Cyanogenmod 7.1 for sometime now...maybe 6 months lol havne't been on here in a while. I leave the 3G radio off due to it sucking battery faster than anything else. Here is what my battery currently says..
11h 11m 24s on battery
Android System--32%
cell standby--32%
Phone idle--30%
Voice Calls--5%
Display--3%
Do these look right to anyone? I would think that if someone turned off all data like myself and only used the phone for texting shouldn't it last all day? I'm lucky to get 15 hours sometimes....I have turned off everything. Bluetooth, Wifi, 3G, all syncing is disabled. I do notice when I turn the 3G radio back on the battery will almost instantly drop 10-15 percent within a couple of minutes...

I don't know what's going on with it. :/
My friend said the same thing about the Android system.
When I have my phone plugged in and am tethering 2 worrying things happen.
A. The phone drains battery VERY VERY quickly, (yes even when plugged in). Quickly I mean like 20-30 percent in half an hour.
B. The phone starts to get very very hot. So hot that when I turn it off, it does not let me charge and instead the overheating icon flashes. If I leave it on, the screen and the capacitive touch buttons start to flash erratically and the back gets even hotter.
This kind of frightens me, is it happening to anybody else? If so can you please post. Also I am using Blazer ROM 3.8 if that makes a difference. Please reply thanks!

Mine overheats when using Netflix over 4G and charging. I run my phone stock and really clean with nothing extra running. Sometimes I get an image freeze and a short sound loop and I have to force shut down. But usually it just tells me that it isn't charging anymore due to the battery being too hot. The battery is always cold, but the phone is hot.
The phone runs hot. Wot wah.
I'm on 3.8 (the first version) I got really confused when he released another one the same day? I have nothing else running and I have not touched any CPU settings, so I'll just have to conclude the phone runs hot. Can this permanently damage the phone? If so what can I do to prevent that. Thanks again for the replies!

Heat is the phone's worst enemy. I love PH and his work but you gotta stay away from heat. It shortens the life span of your phone.

i've definitely had this same exact problem.. Phone/Battery heats up (>40C) and drains quickly with 4g and wifi tethering active. I think overheating the battery like this will shorten the life of the battery in the long run.
Maybe tethering over usb is the solution. fwiw my evo used to tether 4g without this issue. im using blazer 3.9 (upgraded from 3.7, wasnt ever on 3.8) stock clocks/kernel.
Hot LIPOs are less efficient in their discharging and will drain more amp-hours than if they were cold and doing the same things. Running them hot will also shorten their life, correct.
If you battery runs hot, swap it for a cold one* and wait until your battery is cold to charge it off a wall charger or something. These low C rated batteries we use don't really get toasty from just charging, but you are wasting energy trying to charge a hot battery over a cold battery.
*Beer does not supply the minimum 3.7v
This is gonna sound super ghetto, but it's what I do and it works. When your are running your tether, have the phone plugged in, take an ice pack and a couple paper towels. Put the paper towels on top of the ice pack and your phone on top of that and you're golden for about an hour. Keeps it at a nice 25°c

sounds like it would work... but there has to be a better way. I tether at work a lot (to get around pages i use like netflix/facebook and whatnot being blocked) what i've been doing is limiting my tethering based on how warm the phone is, when it heats up past 40 i give it a rest (and get back to work).
Helping me find a lasting fix to this problem will allow me to be less productive, and hopefully extend the life of my s2.
I have been meaning to make a thread on this. It happens when tethering only, that the phone overheats.
The reason being is the power management for tether I think got bonkered with the addition of 4g tether. Something is not optimized. The battery level literally deplete 10% within minutes
I've overheated to the point where my vibration motor makes noise, and got corrupt data twice. So now I have to tether with a glass of ice on my phone, ice pack would be better.
I appreciate the tether, but the trade off is ridiculous.

See, this is weird... I've been wondering why my phone DOESN'T heat up appreciably while tethering, w or without 4g. My og epic always would for sure. I do the same type of browsing on tether with this phone (not super intense, just browsing, but it always heated up the og epic) and the phone stays cool to the touch, or maybe just barely perceptibly warmer. Not even enough to make me check batt temp.
I'm running stock rooted, using sprint hotspot hack. No overclock. FWIW.

I would just take the back off the phone and have a small fan blow into it. Also I heard underclocking to 800 MHz while tethering will keep your phone cooler.
Thanks for the amazing replies people! I recently switched onto 3.9 and to calibrate my battery I charged to 100% and tethered on 4G for about 2 hours no problem. So I suppose it was just some problem with 3.8 then?
Ditto
Same thing happens to me but from daily use. I'm on the web a lot. I'm rooted but running stock rom. It's been really bad the last few days, especially after I changed the 4G idle speed. So that may be one issue for me. Oh well
I experienced the same problem , but I think it's due to tethering as the CPU is processing and forwarding more traffic . I fixed this by limiting the tethering download speed . I used an app called bandwidth ruler for that . and my samsung SIII is relaxed while tethering
APP:
Bandwidth ruler free on goolge Store
