Very Important Tweaks (NOT ROOTED AND NOT USING ANY TASK KILLERS):
FOLLOW ALL OF THESE STEPS. I WILL EXPLAIN WHY AT THE END.If you don't use the apps I'm talking about, it doesn't matter. You must set up these apps accordingly.
First, 3G and 4G utilizes the most battery because CDMA phones always seek out the best signal. CDMA networks won't give you great battery life but you will have great call quality because the phones are constantly searching for the best signal.
IF YOU ARE NOT USING 3G, LEAVE THE 3G RADIO OFF. IF YOU ARE IN A BAD COVERAGE AREA, A LOW SIGNAL WILL DRAIN YOUR BATTERY ON A CDMA NETWORK.
Yes, 3G and 4G use more battery than Wifi! Use Wifi if its available and Sprint is working on changing the software so 4G isn't as power hungry.
ANIMATED WALLPAPER: If you are not close to a power source DO NOT USE ANIMATED WALLPAPERS. ANIMATED WALLPAPERS CONSUME BATTERY POWER. I use them when I want to show off my phone or if I know I won't be out for long.
WIDGETS: Widgets that need access to the internet in order to update themselves WILL CAUSE BATTERY DRAIN depending upon how often you have the app set to update the widget via the internet.Every app/widget is different but the following widgets need access to the internet:The stock clock/weather widget, any weather widgets, Friendstream, Facebook, News, News & Weather, Sprint Football Live, Stocks, Twitter, Mail, Nascar, and the Market. (For the time being DO NOT USE ANY OF THESE WIDGETS. I WILL EXPLAIN WHY AT THE END OF THIS POST. I WOULD JUST REMOVE THESE WIDGETS FROM YOUR SCREENS FOR NOW.)
SETTINGS: Menu - Settings - Wireless & Networks "4G, HOTSPOT, 3G means Mobile Network, BLUETOOTH, Wifi - Turn off these radios by unchecking the boxes (Turn on when/as needed)
Menu - Settings - Location -"Uncheck USE GPS satellites box"
Menu - Settings - Wireless & Networks - 4G Settings - "Uncheck the Network Notification box if not already unchecked."In order to uncheck the box you have to turn on 4G, then uncheck the box. Remember to uncheck the 4G box. What does this do? It stops your phone from scanning on its own for a 4G signal, which drains battery. When you turn on 4G, the phone will locate the 4G network on its own.
Menu - Settings - Wireless & Networks - Wifi Settings - "Uncheck the Network Notification box."In order to uncheck the box you have to turn on WiFi, then uncheck the box. Remember to uncheck the Wifi box. What does this do? It stops your phone from scanning on its own for a Wifi signal, which drains battery. When you turn Wifi on, the phone will find all the available Wifi hotspots on its own.
Menu - Settings - Sound -"Uncheck Haptic Feedback box"
Menu - Settings - Display - Brightness - "Set Brightness to about 30-40% depending on your eyesight" (Using Automatic Brightness consumes more battery because the feature utilizes a sensor, especially when you are browsing.)
Menu - Settings - Display - Screen timeout "Set to 1 minute"
Menu - Settings - Display - Animation - "Set to No Animation" (This does not cut off your weather animation folks. I have yet to see what it affects.)
Menu - Settings - Accounts & Sync - "Uncheck Auto sync box" All sync circles should go from green to gray, meaning syncing is no longer active for the following:Weather, News , Stocks, Google - Tap News - Account settings - Update Schedule -"Set to Manual"
- Tap Stocks - Account settings - Update schedule - Should be gray in color meaning its not turned on/active - Tap Weather - Accounts settings -Set to minimum usage for your use! (Once a day is all I need)
I leave background data checked so I don't have to always check the box in order to enter the market app. Since we turned all syncing basically off, background data will not cause any problems.
Open Mail App - Menu - More - Settings - Send & Receive - Set Frequency for Peak & Off peak times to "ONCE A DAY" - Menu - More - Settings - General Settings -"Check Refresh upon Open box"When you open your mail app it will automatically download your mail upon opening. You don't have to use this function if you only check your mail once a day because that is what we set the mail app to do. But if you check your mail more than once a day, check the box so you control your battery consumption by manually checking your mail.
Open Fring App if you have it - Make sure you are signed out and logged off when closing. Menu - Settings -"Uncheck Automatic Startup"
Open Sprint Zone App - Menu - Settings -Set Update Frequency "Select Every month"
Open News App - Menu - Settings -Set Update schedule - Make sure it says "Manual"
Open Stocks App - Menu - Settings - Make sure Auto Sync data and Update Schedule boxes are grayed out and no check in the Auto Sync Data box exist.Uncheck the "Update when Opened box" if you do not use the stocks app. If you use this app, its basically set to manually refresh upon opening if you leave the box checked.
Open Weather App - Menu - Settings - Ensure Update Automatically Box is Unchecked.This will allow you to refresh your homescreen clock/weather widget by hitting the refresh button in the lower left screen of the weather app.
Open Talk App - Menu - Settings -"Uncheck Automatically sign in box" and make sure you sign out. Do not back out, SIGN OUT
Open News & Weather App - Menu - Settings - Refresh Settings - "Uncheck Auto-refresh box"Now you can manually refresh your weather opposed to the app doing it for you and depleting your battery.
I DO NOT USE FACEBOOK, FRIENDSTREAM, OR TWITTER SO IF THOSE APPS HAVE SEND/RECEIVE SETTINGS YOU MUST SET THEM UP ON YOUR OWN.
With my setup your phone should drain in idle mode at 1% an hour. I can leave the Wifi and GPS Radios on, and my phone will still drain at 1% an hour while in idle mode. As long as the phone isn't sending/receiving data while in idle mode. You will see the 1% an hour battery drainage. When I say idle mode let the phone sleep for 2 hours and see what drainage you get. You should lose 2% and start from a fully charged battery.
Now you must work backwards folks. If the phone is draining properly, set up your apps to the frequency of how often you use the apps but you want them set to minimum usage. Don't set up mail to send/receive every 4 hours if you only check your mail once a day. Don't set up weather to send/receive data every 3 hours if you look at the weather once a day. That doesn't make sense. When an app needs access to the internet via 3G, 4G, or Wifi its going to consume battery life. So if you have 3 apps scheduled to send and receive data 4 times a day, your battery isn't going to last an entire day. That's why we tell everyone the EVO will use battery based upon how you setup your phone. That's if you even set up your phone.
Set up your apps. See what type of battery drain you receive over two days. Then if your battery drainage isn't bad then set up your widgets. Or you can do your widgets first, wait a few days and see how your battery drains, then set up your apps to minimum usage. Does this make sense?
After a week and you are happy with your setup and battery drain, play with the auto brightness features and animation settings to see how that affects your battery. Its a give or take thing with the EVO. You can't have all the bells and whistles on the phone going at once. Use what you need on the EVO.
The best way to get 100% juice out of your battery is to UNPLUG THE PHONE FROM THE CHARGER WHEN THE LIGHT TURNS GREEN. YOU WILL NOT SEE A 5% DROPOFF IN BATTERY POWER IF YOU UNPLUG THE PHONE AS SOON AS THE PHONE INDICATES FULLY CHARGED.

Great post, and I especially agree with the quoted part above. Once you've optimized your battery life, you can then start tuning things based on your actual needs. I've gone a step further and done some tests on the effectiveness of certain battery saving tips; think of it as a cost/benefit analysis.
Haptic feedback does not put much of a dent in battery usage, so if you prefer the tactile feedback, keep this one on. You'll still have great battery life.
Weather syncing does not drain very much battery, especially compared to exchange activesync, facebook feed, etc, mainly because there's so little data being transmitted. So if you like to have accurate weather, you can keep it syncing every hour without much impact to overall battery life.
I've set screen timeout to 2 minutes because I hate having the screen turn off on me if I'm reading some email and/or thinking about what I'm reading. But I also make it a point to hit the power button when I'm done with the phone, so the screen isn't ever on more than it needs to be.
Same for brightness. I keep it on auto because I want the phone to be readable when I'm outside. I used to have it set at 10-20%, which is fine indoors, but when I go outside, I had to manually turn it brighter. Too much of a pain. Again, I just shut the screen off every time I'm done with it.
But, yeah, overall, this is a very good baseline for all Evo users. It definitely covers all the major battery drainers. No need for task killers if you follow this guide.
For rooted users with CPU throttling enabled, you can get even better idle battery usage. My overnight drain is 1% in an 8-hour sleeping period. And everything still works: emails come in; led indicator works, my daily alarm goes off, calendar notifications kick in, etc.

I want this to be clear. The EVO loses battery power through idle time drainage and through usage drainage. However the phone drains through your usage nobody can fix that. If you have apps sending and receiving data while you are on the internet I dont think your battery is going to last 4 days if that is what some of you are expecting. I can fix your phone if you are losing battery as the phone sleeps but I can't fix how you use all the battery power in your phone. Remember its a phone first. This phone can go days using it strictly as a phone.
If you want 2.5 to 3 hours of additional battery juice get the Seidio 1750mah battery like me. The stock battery will get you 4 to 4.5 hours of NOTHING BUT STRAIGHT INTERNET USAGE. The Seidio 1750 will get you 6 to 6.5 hours OF NOTHING BUT STRAIGHT INTERNET USAGE. My DELL laptop can go for 2hrs and 30 mins on a single charge in comparison. I use my EVO more than my laptop browsing now. You can either use your laptop folks for 2hrs to browse or use the EVO to browse for 4 hrs or in my case 6hrs.

For some reason after doing all of this, my battery is going down 3x faster than usual..no idea what I did wrong. It went from 100% before I went to sleep at 2am to 28% when I woke up at 10:30am. I checked to see what has been using the battery and besides standby and idle, it said Android OS and Android System. It wasn't like this before so I'm wondering what I could've done?

Can anyone help me out here?..I can't figure out what is using the battery so freaking much. I don't know why my battery use is saying Android OS and Android system, what could be running? I did all of this right before I slept so I didn't even touch my phone after doing this. I backtracked and still can't figure out what the hell I did that is causing the phone to be draining my battery like crazy (just drained 5% in 13 minutes doing absolutely nothing but check the battery percent every couple minutes). This is driving me nuts.

I just got a 1750 MAH battery, now I was wondering is it normal for the battery to drain kind of fast at first? I mean, while using my original battery with the settings posted within this thread my battery life was long lasting. However, I installed the new battery, charged it up, unplugged it as soon as the green LED appeared, but I noticed an immediate drop of 2 to 5%. Please tell me that is normal for first time use.
Thanks so much for these tips. Some are things I would have done myself, but others are options I would never have even thought to find! One question:

Does this mean that sub-options that are checked are still active even if the main option is unchecked? So in this case, even if 4G is turned off, the phone will still constantly search for a 4G signal if that sub-option is checked?

My Seidio battery came with specific instructions. If you buy a new lithium ion cell phone battery you are supposed to charge the battery in the phone for about 11 hours with the phone off. The LED will turn green after about 4 hours but the battery isn't fully charged. So the battery will basically lie to you so you think the battery is charged but its not. Brand new lithium ion batteries must be initialized. The companies that make the batteries do not initialize the batteries anymore. It's the buyer's job. Through initialization, you allow your battery to reach its maximum charging capacity by allowing it to charge for 11 hours.

Does it hurt the battery not to initialize it (for 11+ hours) on its first charge?
It doesn't hurt the battery per say. By initializing the battery you are telling the battery its maximum capacity. If you don't charge the battery to maximum, then the battery will never figure out the largest charge it can take. Not initializing the battery, you are basically telling the battery what it thinks its maximum capacity should be. The battery memorizes its maximum charging capacity. I do not know if you can initialize the battery after its first use.

I had a similar experience on my first night. My battery drained after about 2-3 hours of use, but then after charging it overnight, it has since consistently given me 12+ hours. In one case, more than 24 hours, but I didn't use it that much during that time.
With Slick's tips, and even with 3G turned on, my battery seems to drain at less than 1% per hour while idle.
I don't know about initializing a battery, but like he said in his reply to you, my experience has been that immediately taking it off charge when the light turns green (I'm talking about any device, not just the Evo) doesn't seem to give a full charge. That's why I let my devices charge overnight, in a sense "overcharging" them, but that seems to ensure that they actually get fully charged.
I've been lurking/reading for a while, but have something I can finally share that I have seen re: battery optimization.
I have seen a marked improvement in battery life by going into the Qik app, and going to Menu>Settings and change the "Sync Video Chat" to only sync when the app is opened, instead of every 15min. like it's set to from the factory...anyone else try this?

Hmm, I just realized that I opened Qik for the first time the night before my battery seemed to start draining a lot, and now I see that it has been running since then, presumably syncing every 15 minutes! Thanks for the tip! I turned off the syncing and also signed out completely (although it still shows that it's running) and I'll see how that goes.
If it's still running later, I guess I'll have to try to Force Stop it. I never noticed if it was something that just remains running even if you never opened it before or don't use it.
Thank you for your post, Slick1020. I have followed these steps and noticed a huge difference in my battery life. I hate having so many apps running that I don't use, especially when they are constantly sending and receiving data throughout the day.
I have one really important tip that I didn't see in your post. I posted it to my blog. Feel free to add it to your post in this thread so everyone can see it, or just use the permalink below.
So why does the EVO scan the GSM if we only really need CDMA?
That is a good question, and I do not know the answer. I wonder if other HTC phones designed for use with the Sprint network share the same default setting?
I've noticed that the EVOs in use at my company that don't have this problem are the ones that have already been updated to Froyo (2.2). Maybe someone recognized this as an error and fixed it in the update?
Menu - Settings - Location -"Uncheck USE GPS satellites box"
So far I haven't noticed any extra drain with GPS always on, so if you use it a lot you may want to try leaving it on and seeing how the battery does. It doesn't seem to be actively used until you open an app that uses it.
(Having Wi-Fi on when I'm out of range of my Wi-Fi also doesn't seem to do too much to the battery, at least not for short periods of time.)
HUGE THANKS this thread is great. i followed all the steps, charged the battery to 100% and went to sleep. when woke up 7 hours later it was still at 100% its been over 13 hours since my last charge and ive had some medium usage (e-mail, youtube, angry birds) and the batt is still at 58%. really need this to be sticky for new users like me!
Thanks for the tips, I just implemented them and will report if it helps.
Anyone know how long these batteries last?
I usually bounce back n forth between the OEM and Seido 1750 but man, I just noticed an enormous battery drop (19%) this morning, from 100% to 81% with ZERO use after approximately 3hrs. I don't know if the battery is on it's way out or if I got a lot of garbage running in the b/g!?!?!
Also, maybe it should be noted that the mail settings need to be changed in EACH account?
And that it's normal that you wont even have access to mail after turning off the 3G w/out turning it or wifi back on? Or was that just something that affected me in my area?

With about 2 hours of usage, I've gotten 24+ hours out of mine several times. However, on any given day it may also do what you described, dropping quickly in the morning.
Since I can normally get good battery life, I'm inclined to believe that these "bad" days are the result of some app or process draining the battery. I just don't know what causes it to happen, because it seems to happen without me doing anything special (like installing something new, leaving something open, etc.)
You might try as someone else suggested and get an app like Spare Parts and use it to see what's draining the battery on those bad days.
SLICK1020,
Great stuff! I was a little disappointed with the battery life of the EVO. I just defected from the "should I say it" iPhone 4 which had killer battery life but was locked down and as I learn more about the EVO I found that I have soooooo much more choices within the phones systems and apps that are active. While these "choices" are great, it is up to me to decide what I want running and what the battery trade off would be. Kudos for the info!!
So I read through these tips, and I must say that they disappointed me. For the most part it is common sense. The biggest issue I had with these "tips" is the recommendation to turn things off. If I follow everything on this list I will probably have my battery last a week, but I will also have an OS work and feel like the iphone (no widgets, no data updated on the fly, etc.) I will have to seek all the info. I need rather than have it at a glace. Honestly, if all I need to do is make phone calls and check the time, I can get that with a much cheaper "dumb" phone which has a battery that will last an incredibly long time without a charge.
If I may make a slightly better suggesiong (well I consider it better):
Look into the app "Green Power". It basically allows you to kill/set data transfers at various times. The free version lets you set it for the daytime only, while the paid (costs 97 cents) version lets you set a night mode as well. You can do things like set the 3G data radio on once every 10 minutes (this is a changeable setting) and stay on for 1 minute (also changeable). You tell it how much or how little to control. If you look in your battery management, you will see that the data radio is what drains most of your power throughout the day. For me, the free app is sufficient since I always have the phone plugged in overnight, but I decided to pay for it since I liked it so much and thought it was a truly great app.
Some things to note is that apps like gmail will only update in the intervals that you allow the radio to be on. It is also worth noting that when you wake up the phone, all of these radios are automatically allowed back on, so you don;t need to worry that your info will be out of date or that you won't be able to quickly browse the web.
EDIT: I also thought I would add that the live wallpapers are only going to drain more power while the phone is awake. Once the screen is locked again the animation becomes suspended.

But, I'm of the "why turn off all the good features of a device for a few more hours of battery life" mind.
About all I do is use static wallpaper instead of the default live ones, and do all my syncing and updating (gmail, weather, etc) manually on demand, rather than having that stuff configured to autosync, etc.
I wanted to post my thanks for these tips. Clicking the Thanks button didn't seem like enough. I couldn't understand why my battery would drain 10% right off the bat when I was simply playing Droid Words with my screen set to timeout at 2 minutes. I'm not interested in the stocks, auto-syncing, and news, etc. so I've used your settings recommendations. I've removed the weather widget and a couple of other things from my home screen. I'm hoping to see a major change in battery drainage now. Thanks a million!

if you turn all these items listed why do you need the phone?
Welcome to the forums!
It all sounds draconian - in practice it isn't.
If you hang in a fringe area, turn off always on mobile data, your phone will go back and forth and forth and back trying to figure out what to do, eating battery. Otherwise, you won't notice it.
If you have constant wifi access whenever, wherever you want data services, favor your wifi radio, and turn off 3G if you notice a power difference.
4G radio control had some bugs - the newest update should really alleviate all of those.
And your phone + sms stuff will all work regardless of those settings.
For data services - turn off what you're not likely to use - services constantly babbling on the web behind your back - for an app that you might check once a day - can be updated by their refresh buttons when you use them, rather than waste a lot of juice doing constant input/output that you're not concerned about.
It's not the phone that's the problem - per se.
It's that Sense is more than a UI, it's a unifying concept to bring all of your net-based social interactions into a unified framework.
Boooookay.
Problem is that each social networking or messaging app thinks it's the center of the universe and should engulf and devour all you do.
Add that behavior in with a phone with a lot of easy-to-configure-wrong radios, and there's the issue.
So yeah - Sense and those apps are all on the Evo, so from a certain point of view - it's the phone - but just as you wouldn't try to run everything at once on your laptop while on battery, from that point of view, it's not the phone.
Congratulations. You have now turned off every reason why you bought the phone in the first place.
Not really. I've been doing most of the things mentioned in this thread, not everything. I'm rooted, and have wifi, 3g, bluetooth, and gps toggles in the pull down notification bar. I just leave everything off, and it literally takes 2 seconds when I need it. I update my weather once a day, or if I really need to know exactly what temp it is in my area, it takes 3 clicks. I get email from all my accounts with 3 clicks anytime I need it.
No, my phone does every thing I bought it for, and much more. But now I use my phone as much as I want, and have 40% battery after a 17 hour day.

I'm not sure what you're referring to, but if you mean the general tips on what to turn off to conserve battery life, then you can't make such a general statement as that. Not everyone buys their phone for weather, or stocks, or instant messaging. Knowing that these things may be on by default and that turning them off helps save the battery are great tips.
The only significant thing that you might turn off is mobile data, which of course disables everything except phone calls and texts. But even then, sometimes this may be all you need to do during the day, so it helps to know that turning 3G off is an option. I honestly didn't realize that 3G only affected data and that I could continue to make calls and send/receive texts without, until I read this thread. And if I happen to go into an area with little or no 3G, there's definitely no reason to leave it on.

Wow, I didn't realize how much of a difference taking the phone off "auto brightness" would make. Just with regular use alone, I gained 20% battery for an entire day.

does it to that even if you have never signed in to qik?
edit: nvm remembered I just rooted and froze qik so it shouldn't run/update anyway
just wanted to say thanks a lot for the post. have had the evo for a while and finally starting to get into the different roms out there after rooting in nov, have stuck with the same rom for fear of setting everything back up again (much easier than i thought it was going be) and tweaking the phone so naturally battery is always an issue
have the extended battery and love it, actually thinking of buying another one instead of going back to the stock battery after the extended goes down. but i digress just wanted to say thank you, knew most of this (through other member contributions) but still helpful nonetheless
more posters should think like this especially if they are more knowledgeable about the topic. love guides like this and is a great service to those who might not know as much.
Battery Tweaks For HTC EVO 4G
