    I ordered the Seidio 1750mAh battery, and was so excited to get it. Charged it 11 hours. Put in phone yesterday. On standby, fell to 75% in less than 2 hours. Called Seidio. I am told our phone's software is incompatible with their batteries, that they are not responsible. So, Visa dispute on 66.00 battery that lasts less than 4 hours on standby.

    Then why sell a battery labeled for the EVO??? That's ridiculous, I hope you get everything sorted out.



    With the standard battery I am getting AT LEAST a full days use out of it. I unplugged my phone at 9pm last night with 90% battery, played Zeus Ex and SKOB2 for about 45 minutes, surfed the net a bit, sent some texts, passed out without charging the phone and woke up at 10 this morning and there was still 67% on my battery. 23% in 13 hours? That's pretty good, methinks.

    Thanks, and sorry if my posting is formatted wrong. I'll get the hang of it! I fought with Seidio 2 and a half hours. The outrage was 'Rachael' telling me I shouldn't have bought a 3rd party battery. I am back to the OEM. I have almost everything turned off, mail is at 4 hours, weather at 6 hours, and ATK killing every hour. As with my Hero, previously, Up to 20 apps randomly open. Overnight, off the charger, it uses 10% on the nightstand. I turned off auto on network, and set to Sprint only. Also, my Hero's, the one Sprint tried to update, and bricked, as well as the new one they replaced it with, and now my EVO, overheat if the phone is used while on a car charger. Nobody, including HTC, tells me they have ever seen the LED flash amber, green, amber, etc. When I installed the battery widgets, they all said "overheating" while it flashed. Has anyone else seen this, 'cause the HOW has to be used on the charger. Sprint has tried 3 different chargers.

    I have an extra OEM battery I bought at the Sprint store, but am afraid to keep removing the back. It just seems flimsy to me, and I don't want to break off a clip. Love the phone....spending s fortune trying accessories, though. Anyone know anything good or bad about the Amzer 1800? Take care.

    Smile Good recommendations and thanks!

    1. Lower screen brightness. Go to Settings -> Sound & display -> Brightness. Slide the brightness switch to the left to lower it or check the "Automatic brightness" box to let the EVO use its sensors to adjust the screen according to the ambient light. You can also find dedicated screen brightness widgets in Android Market.

    2. Turn off 4G, WiFi, GPS, and Bluetooth when you don't need them. The easiest way to manage these wireless radios is to use the Settings widget preinstalled on your EVO. Tap the + button on your home screen -> Widget -> Settings. Once your chosen widgets are on any of your home screens, a simple tap turns each one on/off. There are other widgets that do this in Android Market, but these are already preinstalled and they're a nice-looking set.

    3. Disable WiFi and 4G network notifications. Go to Settings -> Wireless & networks -> Wi-Fi settings. Uncheck the Network notification box so the EVO isn't constantly scanning and looking for open networks to tell you about. For 4G, go to Settings -> Wireless & networks -> 4G settings.

    4. Disable "always on" mobile data. This is one of the biggest battery savers. Go to Settings -> Wireless & networks -> Mobile networks. Tap "Enable always-on mobile data" to uncheck the box. I haven't found a negative consequence of disabling this feature, as Gmail and other apps/functions still work perfectly.

    5. Turn off background data. If you're not using Google services, go to Settings -> Accounts & sync and uncheck the Background data box so that applications cannot sync, send, and receive data whenever they want to.

    6. Lower the screen timeout interval. The EVO's screen can be set to automatically turn off when you don't interact with it for a predetermined amount of time: 15 seconds, 30 seconds, 1 minute, 2 minutes, 10 minutes, or never. Depending on what you're doing, a too-short interval can become annoying (especially if you didn't disable your lock screen), so choose wisely.

    7. Manually turn off the screen when not in use. Since the screen timeout function ensures that the EVO's screen will turn off (unless you have it set to "never turn off"), it can be tempting to put the phone down when you're done using it and just let the screen turn off by itself. Instead, give the power button at the top of the EVO a quick push to turn it off manually.

    8. Turn off auto-sync. Go to Settings -> Accounts & sync -> Auto-sync.

    9. Change auto-sync frequency (Weather, News, Stocks, Twitter, etc). If you don't want to turn off auto-sync, you can adjust how frequently data is retrieved/updated. The settings vary depending on the app (and some don't offer the setting at all), but it's generally found in the same place: Settings -> Accounts & sync. Select an account from the list and then tap "Account settings" to change the sync frequency.

    10. Disable wireless network location services when not needed. Go to Settings -> Location -> Use wireless networks. Note that this (or one of the other options) needs to be enabled if you want to see and/or use your location in apps like Maps.

    11. Turn off window animations. I know it's nice to look at and fun to show off, but eye candy uses extra power (albeit not very much). To turn it off, go to Settings -> Sound & display -> Animation -> No animations.

    12. Don't use a live wallpaper. Live wallpapers were one of the new features in Android 2.1, so it feels like a step backward not to use them. They don't hit the battery very hard when used, but they do make a small dent. So if you're trying to improve battery life, even if only incrementally, use a static wallpaper instead.

    13. Use a dark wallpaper. Some say that dark wallpapers are more energy efficient than light wallpapers. Others say it doesn't make any difference. Either way, there's no harm in using a dark wallpaper so you may as well do it.

    14. Change WiFi sleep policy. This may sound counter-intuitive, but leaving WiFi on when the EVO isn't being used and the screen is off is actually better than letting it sleep. When WiFi sleeps, 3G/4G wakes up to sync, get email, and retrieve other data. 3G will eat up more battery than WiFi, so go to Settings -> Wireless & networks -> Wi-Fi Settings. Press the Menu button and tap Advanced, then Wi-Fi sleep policy. Choose "Never" from the pop-up menu.

    15. Monitor your running services (or consider using a task killer). Just because Android 2.1 is supposed to an intelligent operating system that will manage your running apps for you doesn't mean it will always do things the way you want them to be done.

    You can take matters into your own hands by going to Settings -> Applications -> Running services, where you can view what your EVO is doing and manually stop certain activities. You can also download a third-party task killer from Android Market and kill selected apps to free up some resources and potentially save some power. Task killers are a polarizing topic in the Android community, so tread lightly when looking for recommendations or asking for help with them.

    16. Choose your home screen widgets carefully. Widgets that need access to the internet to update information (e.g., Facebook, Twitter, Engadget, Slacker Radio, Weather, Stocks, News, Mail) can suck up a lot of juice if not managed well, so choose them carefully and set their sync/update frequencies to a reasonable interval.

    17. Disable notification lights. This may not be practical if you're someone who really needs/wants to know when something happens on your phone when you're not looking, but for everyone else, feel free to turn off those notifications. Go to Settings -> Sound & display -> Notification flash and uncheck all the boxes.

    18. Turn off phone vibration. If the ringer is on, why do you need the phone to vibrate? You're already in a loud environment that drowns out the ring; answering the call won't quiet your surroundings so you can hear what the person at the end of the line is saying. If anything, you're just adding to the noise by yelling, "What? What?" into the phone.

    And if the EVO is set to silent, then an incoming call should be silent. Yes, the buzzing vibration may not be disruptive as your ringtone, but people still hear it.

    So go to Settings -> Sound & display -> Phone vibrate and turn it off.

    19. Turn off audible touch tones. In Settings -> Sound & display, uncheck Audible selection and turn off Audible touch tones.

    20. Turn off haptic feedback. Once you get the hang of typing on the EVO's on-screen keyboard, you can turn off the haptic feedback that was turned on by default. Go to Settings -> Language & keyboard -> Touch Input -> Text input -> Vibrate when typing.

    You can disable haptics in other areas of the system by going to Settings -> Sound & display -> Haptic feedback.

    Thanks for the tips. I am getting my wife the EVO today and want to set her up so the phone only needs charging daily and the tips should help, so thanks again!

    New observation. I have my EVO for almost 1 week now and I noticed that after an overnight charge when I unplug the cord the battery meter goes down to half full. What do you think is going on? Do you think because it is a brand new battery that it will take sometime to fully charge? I have also left the battery running until it warns me to shut down due to low battery. This is interesting..thought if other users notice the same issue or it's just me, thanks.

    Not sure if it will help, I posted this on another one of the threads but this was a thing I found. i did it along with some of the same things metal head found and went from 3 to 4 hours to well over 20 hours now. I do notice a 15 percent drop off pretty quickly, but very slow after that and I am hearing that is because of the kind of battery. Anyway you can try the same things and see what it does for you.

    Plug the phone it and when it turns green leave it for about 15 minutes. Unplug it and then turn it off and plug back in. Wait for the light to turn green and unplug. Then turn the phone on, then back off and plug back in until green. once it goes green this last time unplug and go. It is my understanding that this is a one time thing. I also downloaded ATK from the android market and use it, although some say to have it kill everything when the screen shuts off and I can not find that setting. But I have it on my main page in an easy place to touch and I just make sure and do it everytime I turn off the screen. Also i went to accounts and sync and turned off syncing on news, stocks and weather, facebook (it was not syncing correctly and sending notifications anyway so I figured what was the point). The only thing I have still running really is my gmail. I have not minded not syncing and getting notifications all the time. Thought I would get really mad and almost took the phone back because I got notifications ALL the time for email and facebook and everything and thought I liked it, but boy is my life quieter without. Only concern is if someone is REALLY trying to get ahold of me then it might be a problem.

    nice copy and paste job from here:
    20 tips to improve HTC EVO 4G battery life
    http://www.goodandevo.net/2010/06/5-...tery-life.html

    they also added 5 more tips .. check them out

    As a follow-up to G&E's 20 tips to improve HTC EVO 4G battery life, here are 5 more tips (all submitted by readers!) to help you get more runtime out of your phone.
    These tips are only meant to serve as guide. You do not have to apply all of them. Please pick and choose which ones suit your personal usage of the EVO.
    Continuing on from the previous 20 tips . . .
    21. Disable data roaming if you don't need it. Go to Settings -> Wireless networks -> Mobile networks. Tap "Data roaming" to uncheck the box to prevent the EVO from going into roaming mode when it encounters a weak signal. Thanks for the tip, Chris!
    22. Make sure CDMA is the preferred network type. It seems that some EVOs were incorrectly set to GSM before they were shipped. This causes the phone to constantly search for a GSM network to connect to, which of course drains the battery.
    To check the preset network type on your EVO, bring up the dialer and press *#*#4636#*#* to open a Testing menu. Tap "Phone information" and scroll down until you see "Set preferred network type" followed by a drop-down menu. If "GSM auto (PRL)" is selected, then tap it and choose "CDMA auto (PRL)" instead. Reboot your EVO and make sure your choice is still active. Thanks for the tip, DV8!
    23. Consider using a different messaging app. The stock messaging app was blamed for a lot of battery drain in earlier versions of Android. This issue has reportedly been fixed but you can still download Handcent or any other messaging app to use instead. Be sure to turn off all notifications and alerts in the stock app too. Thanks for the tip, portablealli!
    24. Turn on airplane mode when you don't need network connectivity. This may sound like a drastic tip but when you really don't need to use the phone or 3G/4G (e.g., watching a movie, hiking, other times you don't want to be bothered, etc.), enabling airplane mode using the preinstalled widget (+ button on your home screen -> Widget -> Settings) is an easy way to preserve your battery. A simple tap on the widget is all it takes to re-enable network connectivity, allowing you to make a call whenever you need to. While this may not be practical very often, turning on airplane mode for an hour or two at a time will help. Thanks for the tip, brandon!
    25. Change the CDMA roaming mode. Go to Settings -> Wireless networks -> Mobile networks. Tap on "Roaming" and select "Sprint only" from the pop-up window that appears. Thanks for the tip, Chris!
    ---------------------------------
    Got another tip to improve battery life on the HTC EVO? Please share it in the comments.

    Related to battery life, does anyone know how to turn off certain applications until I need to use them? Observation, every time I open the App Killer I see a list of Apps that are running. I would have to kill the Apps to turn them off. My question is, why are these Apps turned on and run by themselves when I don't need them?

    Is there a way to keep them turned off until I use them?

    There is no reason to kill the apps unless they are actually using the processor. Just having them in your memory does not negatively affect battery life at all. In fact, leaving them in your memory can actually improve battery life because the phone doesn't have to re-load them into memory whenver you want to use them.

    Android handles memory much different than windows. Android actually runs better when it's memory is close to full, compared to windows that runs better when the memory is free. Trust me on this, stop looking at your task manager apps list and just let Android do its job and I'm sure you'll be surprised at how much better your phone runs. The only time I ever kill an app is if it's running (actually using the processor and not just sitting dormant in the memory) and causing problems.

    I recommend using SystemPanel because it actually shows you how much processor a specific app is using. It also separates the list into 3 categories: active, inactive, and system. If the app is inactive, there's no reason to kill it.
