    Hey! Ive been noticing my evos battery is atrocious, and ive also noticed with back light virtually off my display accounts for well over 70% of my battery drain. I got the timeout set to 30 seconds, and the brightness currently between 0 to 20%. any idea why my screen is using such an unusual amount of battery life?

    I posted this in another thread but my battery life has gotten worse since GB. Looking at battery usage right now. Been unplugged an hour and haven't had my phone on till just now. Display (in 2.2 was always in the low teens to single digits) - 70%, Dialer - 13% (haven't used the phone at all), Wi-Fi - 7%, Standby - 6%, Idle - 4%.

    i really didnt get much of a chance to check how my 2.2 usage was, i have read gingerbread kills battery life tho oddly enough, looks like we'll just have to wait until they either fix the battery issue OR someone figures out how to root 2.3 (set CPU is a serious battery saver)

    Yep. I'm just hoping we get root access soon so I can get rid of this disaster of an update. Seems I got most of the bugs I've seen listed.

    I cant imagine it taking another month, should get some good news soon enough. I have noticed that the problem seems to only happen when the screen is actually on so i cant imagine how horribly its coded, i had it idle with wifi on and 3g off for 8 hours and i only took a 4% drain. Within 30 minutes of using the phone for web browsing and such i took a 15% hit. How does something that horribly inefficient get released without being fixed?

    I'm seriously wondering if they actually QA'd the thing considering some of the issues I've seen. Like I know someone at HTC is walking around work with an Evo 4G and Sense is crashing on him while he's trying to do something.

    With GB, I noticed the battery life was actually a little (ok, more than a little) better than with 2.2.

    My parameters (with 2.2 and with 2.3.3:
    I do not use 4G.
    I am usually on wifi (switch to 3G when I am out).
    I do not use skype/IM programs/google-talk etc
    I am usually in good sprint coverage area (no low-signal issues)
    I guess I am a moderate user (10-15 sms, 20-30 minutes of games like PVZ/AB, 15-20 minutes calls, 20-30 minutes of web browsing etc)

    I'm sure you know this, but just in case - when you see display using high percentage of power, that doesn't necessarily mean that your display is using too much power. It just means that compared to other services, your display is using a large percentage.

    Ever since I got the 2.3.3 update, I was able to start using the stock battery (instead of the 2500mAH battery that I used with 2.2). I've moved to the EVO 3D now (similar battery life BTW)

    I know, but im also comparing other running programs too, power whores like netflix afer an hour of streaming are still only using around 5% on a freshly charged battery, when that should be taking atleast 20% of my power. Makes me think that the display is just using a ****** high amount of power, which it is lol. Have yet to see any other android phone suck up so much power just allowing you to see it

    I'm having these same issues. After the latest updates, my display will be sitting at 70% usage, when it's just sitting in my pocket. Totally battery drain in about 5 hours with little to no usage at all.

    I hover around 12 hours of med use with wifi on.


    the key is i turn off auto brightness. I manually set it at the couple notches above the lowest. This saves me a ton of batttery life.

    I have a 2.2 and I've been reading posts advising how to save battery life. One thing I'm confused about is that I can't find the screen that shows which things are using what % of the battery? I go to settings>battery manager> and then I just get the display showing the amount of "battery remaining", but I don't get the screen that people talk about with the breakdown of battery use. Any ideas? Thanks

    Sorry, I hadn't seen the words "touch for usage statistics" until after I sent that query. Duh.

    My wife just got a Sprint HTC EVO 4G and I set it up for her two days ago. I noticed that the dialer app likes to sit at a fairly high percentage in the battery usage statistics. We are talking about 50% battery usage here. This is when she has not even used the dialer for anything at all.

    I have read around in a few threads and it looks like this is an issue that was brought on with the Android 2.3 OTA update. I did not see any immediate solutions to the issue, so I was wondering if anyone has any insight on mitigating this battery drain from the dialer app?

    what software version is on the phone? there was a maintenace ota (4.24.651.1) that was released that fixed some issues with the gingerbread ota (4.22.651.2). not sure is that will fix your issue.

    My wife's Sprint HTC EVO 4G is on the latest software, which is version 4.24.651.1. I believe it was on that out of the box. It is just odd that the dialer is even on the battery usage statistics list at all if she has not made or received any phone calls. My Sprint HTC Hero never shows it on that list unless I make or receive phone calls.

    EDIT: I just found this thread over at xda-developers. It is for the Vodafone HTC Desire HD, but it seems to be having the same issue as what my wife's Sprint HTC EVO 4G is experiencing. They seem to think that the sensors are staying on even when the screen is off and that is why the battery usage for the dialer app is very high. Here is the thread that I was talking about: http://forum.xda-developers.com/showthread.php?t=1069251 .

    I was getting well over 10 hrs before the update. I utilize EasyProfiles to turn on/off 4G, WiFi, Display, etc. After the update I was getting horrible battery life and turned off the Profiles and started setting Display at 0%. As I stated before, Display and Dialer are utilizing upwards of 80% of my battery life between the two of them. Just today my evo lasted 5 hr 24 min or usage that I would have normally gotten 12 hrs out of before GB. If I haven't made this clear, I absolutely loathe what GB did to my beloved Evo. I will be getting a new phone soon.

    I hope they issue an OTA update to fix the dialer usage issue. The screen usage just seems to be a side effect of a large screen.

    My wife manages between eighteen and twenty-four hours on a single charge with fairly heavy usage on her Sprint HTC EVO 4G. I wonder how it would have been with Android 2.2 instead.

    I don't think so. 2.2 my screen usage was regularly below 8%. When I'm at work, which is most of the day, it's set at 0% brightness.

    It could be the way that Android is measuring the battery usage. Perhaps they changed it between versions.

    I heard that Android 2.3 was supposedly much more efficient in terms of app resource management, so a lot other things that looked like they used small amounts of battery in Android 2.2 look like they use more now in Android 2.3 because of the efficiency difference. But, who knows, I just hope that we see some kind of fix from HTC or Sprint.

    for what its worth....display is at the top on all of our android devices. typically at least 80%


    dialer was an issue at release but it was fixed somehow..looks like it is back :(

    my evo is rooted so i cant be much help here but i want to remind everyone of helpful tools like juiceplotter and system panel....both in the market. using strictly that battery screen to eliminate battery hogs is difficult...and there currently is not a spare parts apk that works with 2.3 that I am aware of.

    Yeah. It is weird because the display was never typically at the top on my Sprint HTC Hero, no matter the ROM I was on unless I was heavily using the handset right after I unplugged it and it was NEVER anywhere near 80% battery usage.

    JuicePlotter and SysemPanel are great apps. I have used them all on of my Android devices and I think I will install them on my wife's handset.
