HTC Desire bad battery, how do i improve it?
http://myhtcdesire.com/tag/battery-life
trying this now, but any other?
Actually this article from androidcentral is really complete in terms of settings to reduce battery consumption:

You can also have a look at this one from howtogeek:

When battery drains a lot it is important to find the cause, in this case tools like systempanel are useful, but keep in mind that it is a good thing to stay away from task killers as explained on lifehacker [what are task killers and why you shouldn't use them]:

Hope this will help !
A bad battery is mainly due to either it being faulty or by a stupid amount of usage. Remember that using 7 home screens, live wallpaper, widgets, apps running in the background. All of this counts towards usage. I don't know about calibrating a battery. Some people say it works, some say it doesn't.
I did a little useless experiment the other day where I had my phone at 55% battery and I decided to see how much battery would be used over 24 hours with as little usage as possible. I managed to get 8% of the battery used using 2mA. Hope that puts something into perspective for you.
I tried CPU tuner on the stock ROM and it gave some life to my battery, but I've just flashed a new ROM recently, so hopefully it'll work better.

Can you clarify "as little usage as possible" to get that 8%? Do you mean like switching off everything, or simply not using the device but keeping all the apps as they were?
I Need Help My Batttery Sucks Balls .. Lol Sry but ive been using this epic rom on the newest modem and i mayb get 2 hrs or so on my phone .. which sucks .. how do i fix this ? the battery heats up sometimes while charging ... im sure its the both battery and rom idk?
Did you calibrate the battery? I had horrible battery issues on my hero and started calibrating battery with new roms and has been stellar can't link due to being on phone but search for battery calibration and you will find the post for proper calibration.

calibrate battery thread :]
I've never calibrated my battery and I never will. The phone battery life varies. If your phone is getting hot and dying in two hours, you have a rogue process.
Manage the poorly written applications and you won't even think "battery calibrate" because you'll see upwards of 36 hours of use on your phone.
Realistically, I get about 12 hours of heavy to medium use out of my phone. I do not use any other third party apps to manage my phone except for Quick Info Pro and even that is not used for anything more than status review. I handle memory management through the built-in Manage Applications, services, etc. On weekends, when I'm not texting a lot, I have seen 40 hours without charging.
If you only have stock and never install anyone else's applications, you'll see a huge difference in how applications (poorly written ones) can affect your phone's battery life.
See disclaimer.
Good info from othan, exactly what I tell customers who complain about battery life.
I was thinking why couldn't we sum up all the reasons of battery drain in some thread, so that other's wouldn't have to keep on asking why they were getting one or open a new thread for it.
In almost all cases it's backlight, WiFi, mobile network,bluetooth,GPS, screen time out.
You can also look at battery usage stats in settings to see the responsible app or system setting for battery drain.

How would you go on accomplishing this if everyone has different configurations/settings which affect the drain?

For example, somewhere I read that enabling "flashlight" and "backlight" in quickpanel settings, the battery would drain more.
What I initially thought was that we could post our experiences with bad battery life, the major reasons behind and what we did to solve it. Along with maybe the rom/kernel we would be using.

For over an year, I have flashed my LT15i more than 20 times, trying all the official firmwares meanwhile (all rooted, of course). In my opinion, the daily consumption depends if I used more or less the radios, the players, the screen aso. Because my habits are more or less the same (I listen music and I read/navigate during my half an hour way with the subway, for example) I can affirm that the consumption is constant, around 40% daily. But, I consider that a good estimate could be done following the battery consumption by night. For me, this consumption is around 5%. With one exception: I had installed once an application (from the market!) which downloaded over night almost 10MB of ads, and drained my battery almost 20%! Never ever I have experienced battery drain with official firmwares...
Use BetterBatteryStats and the Android's own included Battery Usage screen and you got all the info you need.
Okay I have a question for the masses here. Why are YOU obsessed with battery life on your SGS3?
I've been through my fair share of cell phones with the latest 3 being the Galaxy S, SII and now the SIII. I've been through a long list of custom roms as well as time spent on stock roms and not once I have I installed a battery monitoring app like Juice Defender, nor have I been interested in undervolting or underclocking as I don't feel the extra battery life outweighs the instability of the phone and the time spend finding the exact perfect values to prevent reboots. As long as I have battery life to get my through the day (which I always have MORE than enough, I'm happy. I'm not a heavy user but my phone gets a workout during the day and I'm never far from a charger which is the awesome thing about having a USB connector to do the charging.
So I ask the question, what is the obsession with battery life? Are you trying to go green and get the most between charges as to not waste power recharging? Do you use your phone so much during the day that you can't make it through the school or work day without it going dead? Are you off the grid living in the bush and only get to charge when you are in town every couple days? Is it bragging rights you are looking for? Why did you spend big bucks to buy an extended battery? Why don't you use the phone the way it was intended to be used and turn off syncing apps just to save a bit of battery? Why do you turn screen brightness down to minimum and leave it there all the time when we have big beautiful screens that look so much better when they are correctly lit up for our surroundings?
I just find it interesting that every ROM thread and every kernel thread and a good portion of the threads in Q/A sections are littered with questions and discussions and arguments about battery life. How to get better battery life, why is my battery draining so fast on such and such rom, what is a good screen on time amount per charge. I don't understand nor can I find an interest in spending time to dissect and analyze everything just to squeeze an extra half hour of screen time out of my phone.
So why? Why are YOU so interested in the battery life of your phone. I'm not looking to make fun of anyone here. Just curious what the obsession is all about and why you are so interested. How does it make your phone or your life easier and better. Maybe I'm missing something.
Well for me, my battery life really sucked and didnt understand why so I started researching and i found out from stock you can do tweaks to improve it and so on and so on.
When I say my battery sucked on stock though it was really bad. I couldnt go a whole day. I would get about 10-15 hours of on time with less than a hour of screen time and my phone would be dead.
I dont care for going 2 days without a charge, I just wanted to go morning to night and still have some juice left. which i wasnt able to do before.

Actually, battery life can have quite a few hours difference depending on your settings, apps, kernel settings and ROM you run. So yes, it does matter if you can get 3.5hrs on screen instead of 1.5hrs.
People don't want to have to carry their charger with them all the time in fear of their phone dying on them in the middle of the day.
For me it is just the simple fact that I can run my phone for almost 2 full days without a charge (not kidding either). But I would venture to say that for most, it is because of the whole reason why many are here. We're Tweakers and no I don't mean Meth addicts. We do it because we can. I don't undervolt at all but I do overclock my kernels a bit (not max) but have found a really nice balance that will give me plenty of time using my phone and not having to worry about charging. Yup, I use my phone.
I smile to myself when I see these screen shots and the line is smooth and flat. Not sure if you are a skier or not but a good analogy is if you see a Double-Black Diamond (expert/steep), there is something wrong. If you see a Blue-Square (intermediate/nice slope) then you are good to go. Green-Circle (begginner/very low gradiant) means that noting is running.
Btw moving to Q&A
I feel the same as the OP. I don't OC/UV for pretty much the same reasons. I don't care. I have run Juice Defender in the past on stock setting values because I was basically lazy and didn't feel like tweaking the sh*t out of it to get the "best" battery life. Not to mention I don't like that it literally turns off your cell radio and initializes it in incremental intervals. I have actually been running an app called One Power that is free on the Play Store and have found it does improve my battery life mostly when my device is idle. But I, like you, am hardly obsessed with getting the best battery life. I don't use extended batteries because I hate how they make the phone twice as thick and I tend to avoid anything non-OEM for obvious reasons. I'm basically happy if I can get through a day on a single charge. I do have a 2nd OEM battery I keep charged in case I don't have time to fully charge up. Our expectations of getting days worth of use on a single charge is just ridiculous and unrealistic. If I cared that much I'd switch to Verizon and get a RAZR Maxx. But that ain't happening anytime soon! Besides, not all phones are created equal so - what works for one person may not work for another. I feel discussions of battery life in ROM development threads are a waste of time and serve only to clutter and detract from development of the ROM. Apps, use, etc are huge variables and will vary greatly from one user to the next. So, when people say "battery life on this ROM is great!" I usually roll my eyes and ignore the post.

Hey, can you shoot me a PM with more about that App. I'll check it out tonight but can you give me more info on it from a real-life user and not some Market desc/review.
Also, report those stupid posts in the Dev threads and we can delete those. I saw one the other day about 5 hours after a ROM came out (new thread and all) stating that the battery life was "Awesome!!!". How in the heck could you know after 5 hours of the ROM being posted (he was not a tester either), let alone being flashed. Rediculousness.

Sure. I just use the default settings the app comes with but you can tweak it to your liking. Will send you a PM shortly.
Edit: I couldn't agree with you more on the battery life postings 5 hours after a ROM has dropped. That's absolutely ridiculous and impossible to gauge so soon. You gotta give it at least a couple days to be able to accurately judge the battery life.

to use the app, root is mandatory? i didnt root my phone, i installed the app, and it shows all the required settings, but when I try to customize, it needs root, my question is, if we use the existing mods, i can use the app, without rooting the device. right?
TIA

Yes. My dad uses the app on his unrooted Galaxy Nexus with no problems. You just can't tweak the settings unless you have root.

Well it didn't take long for even this thread to turn into people discussing how to get better battery life out of their phone! haha. Figures eh?
I work a blue collar job so I need my battery to last all day. I'm not at a desk whee I can charge.......

My friend lost his son and since his phone didn't have juice, he couldn't call 911 fast enough. Had to plug in the charger for like 2 mins first. That's why.

I'm generally indifferent about battery life and attempts to prolong it for 2 reasons.
1. The settings and customization done by the manufacturer are stable values tested and balancing between battery life and the features of the phone.
2.Everyone know what they're getting jnto when they buy a phone with ~4 inch screen,has LTE and top of the line features. It's rather obvious that battery life won't be great, if it isn't then you might as well just go back to the candy bar phones, if you expect the best and the newest AND battery life.I certainly didn't expect my phone to run for 10+ hours when I got it... and besides buying the best phone on the market and then turning everything off to conserve battery life just defeats the purpose. Just buy an extended battery, buy the extra battery OEM and bring a spare along, or have an external charger as well as a 2amp usb charger.
Edit: When I initially got the phone, it was getting 6-8 hours on a charge after a couple of months 12-14 hours per charge. The same thing happen on the JB OTA, Im getting between 10-18 hours depending on my Reddit, Twitter, Gmail and Engadget usage, though I have to admit there are sometimes problems with some apps preventing deep sleep and occasionally what seems to be memory leaks with apps constantly using the data connection.

I like pushing it to see how far the battery can go. I could make it through the day before, but with some compromises. I bought an extended battery and flashed a new rom (which came with some good kernel settings to mess with), and now I can keep everything on and go two days without a charge.
For me it's more about getting what I'm used to--recently switched to gs3 from an iPhone 4, which had amazing battery life. I got around 8 hours screen on with that and initially only 3 with the gs3. So I tweaked away and now it's back to what I expect!
Edit: also I tweaked my way to better battery life because I can--why settle for something that could be better?

I barely got this tablet yesterday and already seeing fast battery drain. I don't have that much apps/games. I rooted it today in the afternoon but I don't think it will drain the battery.... What's the deal here?

There's always an initial drain that is rather fast due to the fact that the charging is not perfectly optimized, notably while it's new. Even though it says 100% it's most likely not the fact. On the other hand due to the large screen the screen uses a lot of power. When using Cyanogen for maybe 20-30 min/day I'm still at 97% the next morning w/o charging. But, I use a lot of mods and settings trying to optimize battery usage. Once you get used to the device and start experimenting with ROM's, settings, mods I'm sure you will find a way to optimize it to your flavor.
The tablet has to scan all directories for media.
Here are some really good tips. You can also shut off a lot of samsung bloatware. I have probably 50 things shut off along with below tips I get amazing battery life and never any lag. Not a fan of magazine touchwiz so using nova and couldn't be happier.

For a new device, you need to cycle the battery to about 10%, then fully charge, to set the battery meter "high" and "low" flags (some call this "calibrating the battery meter"), before you can expect the battery meter readings to be anywhere accurate.
