I think your new-life with the battery has other reasons. Did you also happen to take the OTA just the night before? The OTA made a huge difference.

Did the OTA 9 days ago, b life was worst than before.

Re: Astonishing Battery life discovery!
 

Did you add any new apps like the task killer or startup cleaner? My battery life has also seemed to improve since I got it and I multi-task it but it generally lasts about 7-9 hours. Its possible that since you were not using it and had nothing run besides the system, there was no reason for the battery life to decrease.

Re: Astonishing Battery life discovery!
 

My battery life increased after doing the OTA, of course, I waited until the OTA was rooted and THEN did it.

Re: Astonishing Battery life discovery!
 

well mine has been great I have gotten to 30+ hours on one charge. I normally take my phone off the charger around 8am and by 11pm im at like 40%

Re: Astonishing Battery life discovery!
 

The OTA added 1-2 hours of battery life to my Evo. I use my phone the exact same way almost every single day, so it was an immediate and noticeable improvement. However, I'm also going to test out the OPs theory this weekend. He isn't the first to report this.

Re: Astonishing Battery life discovery!
 

The phone does automatically stop charging after it reaches 100% charge. I found this out when I was charging my phone with a battery pack I picked up at BB. After the phone was charged, the battery pack turned off automatically.

Re: Improve Battery Perfomance on HTC EVO 4G from Sprint
 

To eliminate the 10% drop in the first 20 minutes, just charge the battery in an external charger. I do this, since I have spares and a couple of battery chargers, and the difference is night and day. Last night I played a game that drains the battery heavily, so it was below 15%. I normally do not hook it up to a charger overnight, but did so last night because it was so low (I use it for an alarm clock, so I need it to not die overnight). I took the phone off the charger, and, within 10 minutes, the battery dropped to 91%. Now, granted, I was using it for those 10 minutes, but still! By the time I went downstairs to leave for work, it was at 89%, which meant it was off the charger for about an hour. I then swapped in a battery that had been sitting in a charger for a few days. It has been an hour and 45 minutes, with 10 minutes of awake time, and the battery is at 97%.

I believe, no matter how you do it, via USB or wall charger, charging a battery inside the EVO does not properly charge it. I get much better battery life than I ever got with my Touch Pro 2, now that I charge the batteries in external chargers.

Re: Improve Battery Perfomance on HTC EVO 4G from Sprint
 

ok I have increased my battery time by 5hrs...... I know it sounds impossible... and I am a heavy user..... I have installed Brightness level and set it to 25% and you can not tell the difference in the display!!!!! I promise.... the display uses all of your battery life... Try it please.......

Re: Astonishing Battery life discovery!
 

I don't see how... yours must've shipped with a different battery than mine.

I've tried everything I could find online to reduce the battery... and if I used my phone, just a little, the battery is about to die by the time i get off work.


Even though I don't use my battery all day at work, it dies.

FYI for those who may be curious... The things that helped my battery the most was removing my music from my sd card, and turning off syncing of background data when I'm not using the market which requires this feature to be turned on.

Re: Improve Battery Perfomance on HTC EVO 4G from Sprint
 

Just got two extra batteries and a wall charger in the mail from ebay. Cost like $10 bones from a dealer in Hong Kong. Took my red HTC battery out of my evo and charged it on the charger last night. Put it in my evo this morning at 6:30 am Arizona time and I currently have 28% as I write this (7:25pm). This is the best battery life I've had since buying the evo 3 wks ago. I think it has to do with charging the batter in an external charger. I'm going to use my extra battery tomorrow to see how that one works.

All in all, I'm extremely pleased. Got a whole day of medium use out of my phone.

I'm rooted with OMJ eclair 1.6 rom. If you want info on the dealer on ebay, let me know. Very cheap and the shipping was only a week to the states.

Re: Improve Battery Perfomance on HTC EVO 4G from Sprint
 

Disable automatic sign in on GTalk and you will greatly improve battery life!

Also, turn off wifi, bluetooth, location and 4g when not in use!

Re: Astonishing Battery life discovery!
 

I think that people are judging battery use by holding and playing on the phone nonstop...if that is the case, 4-8 hrs is EXCELLENT! Quit complaining! If you are just using the phone -regardless of the apps- and you actually put it down some to enjoy life you can get over 12 hrs. I get 15+ hrs of use daily and my usage is as follows: wake up and play several rounds of YAMS/YAHTZEE... Play MRacing...check email... look at a video or two. Put phone down... text all day off and on... make calls during the day...usually averaging 10-15 each call.. some calls have been over an hour. Play some more rounds of YAMS...periodically check my facebook and make sure I check Android Mate to see that programs were closed by task manager. I've transferred albums via blue tooth to my brother and various apps during the day.. the longest my phone has gone is 1 day. I have my battery use and percentage widgets and have monitored this for past two weeks before deciding to post. I run Fresh 1.01.. and use LauncherPro Plus as my default home.

Re: Astonishing Battery life discovery!
 

Oh I must also say that I don't know how to change anything so the only configurations are what has come with rooting and the Fresh Rom... The only thing I've done is make sure that I set facebook and weather to update manually instead of all throughout the day. I also make sure that after I've opened several applications that I stop them using Android Mate...even though I have a task killer, it appears to kill just the app but not the other items the app uses. So I perform some manual stops during the day. Other than that I just use the phone and it is lasting me all day. When I want to listen to music or play tv for an extended amount of time I keep it on charge...that's the beauty of having the usb cord... A car USB charger is around 14 dollars at Walmart... it is invaluable. Also, I try to power off the phone once a day and I try and not constantly charge during the day. I like to take off the charge and not plug in again until its down under 10%. I'm no expert but I hope this helps someone.

Battery Life is a beast on Netarchy rooted froyo
 

So I have been unplugged for about an hour, light use and I'm still at 100%. normally after an hour of sitting here idle i would still lose percentage and would be about 92%... So I'm running juiceplotter to track my battery life and will post a pic a lil later after normal use... cuz I'm a heavy user! here's the rom link if needed: http://forum.xda-developers.com/showthread.php?t=743352&page=17

Re: Battery Life is a beast on Netarchy rooted froyo
 

I think the % is misleading, especially after it is fully charged. Sometimes when I unplug, it instantly dropped to low 90s, and sometimes it stayed on 100.

I wouldn't claim it has a better battery unless you go through a normal usage with it.

Battery Life After Official Froyo OTA Update on 8/2
 

I was wondering if anybody else was seeing unbelievably bad battery life following the official Froyo update last night, 8/2. I was surprised I didn't already see a thread near the top for this already, perhaps everybody overslept due to their phone dying and their alarm not going off? Or perhaps I'm alone in this. Now I know that this phone has not been the best battery-wise anyway, but last night before I went to sleep around midnight EST I put a new battery in and within minutes it was already down to 88%. Somewhere around 4 AM or so I was woken up by the vibrations of the phone shutting down. I was quite confused as I usually only lose somewhere between 4 - 7 percent or thereabouts overnight. I shook my head in wonderment and threw a new battery in which read an initial charge of 88%. As of this writing I'm now at 22% and under the 'About Phone\Battery' page I'm showing 'Up Time' and 'Awake Time' having identical values of 4:25:00 and under 'Battery Use' I'm seeing 'Cell Standby' = 50%, 'Phone Idle' = 41%, 'Android System' = 7% and 'Display' = 2%. Information on my setup is minimal, I've not done any rooting yet, I was up to date otherwise with official releases. So...is anybody else seeing this kind of behavior and if so any suggestions on what can be done to fix it? Thanks!

Re: Battery Life After Official Froyo OTA Update on 8/2
 

My battery was fine. Still had plenty to spare this morning and my alarm worked as well. The upgrade put back the default settings like the background processes I suspect. i turned all of that off again. The new Applications manager in the settings is great because you can stop processes easily.

Your awake time and up time should not be the same. There are many threads on this. You have something running in the background. I'm on my phone on my way to work so I don't have time to find the thread for you. I'm sure someone here can point u in the right direction. I think one main issue people found was a calendar and events issue...

Re: Battery Life After Official Froyo OTA Update on 8/2
 

Don't forget to go in Google talks app and disable auto sign it!!!!

Re: Battery Life After Official Froyo OTA Update on 8/2
 

Yeah, on the awake and up times I'm aware that they shouldn't be the same which is why I listed them. What I don't understand is why all of the sudden they are doing this, as they weren't running in tandem before the update. My guess is that I've got some program installed that isn't playing nicely with some new code in the Froyo base? The question is how to find out which? Regarding the suggestion about Google Talk, I'm not running that, or at least I wasn't prior to this update. Thanks for the suggestions, keep 'em coming, I still have my doubts that I'm the only one affected given how radical of a change it was.

Re: Battery Life After Official Froyo OTA Update on 8/2
 

Do you have LED Light installed? It is not compatible with froyo and will run continuously.

Re: Battery Life After Official Froyo OTA Update on 8/2
 

Aha!!! The Iceman cometh and saved my day! I did indeed have the application he mentioned directly above installed, and once I uninstalled it and waited a few minutes and checked my uptime and awake time they were starting to diverge. I think that will do the trick. Thanks again Iceman5000.

Re: Battery Life After Official Froyo OTA Update on 8/2
 

My guess is its something with froyo and some apps.. or widgets. I'm wondering is the culprit launcher pro for me because im having the same issue.. and had it with the leak too. I fixed it with the leaked version but after doing this update its right back to the same thing. What's the easiest way to tell whats keeping the phone awake?

Re: Battery Life After Official Froyo OTA Update on 8/2
 

I had the same issue. The awake and uptime values were the same, and my battery was draining quickly. I went ahead and uninstalled a bunch of apps that I didn't like or stopped using and the issue seems to have gone away. The values are different now.

Re: Battery Life is a beast on Netarchy rooted froyo
 

I ran the earlier leaked rom and my battery life was amazing on that too. Gonna wait for OMJ to create a custom rom before flashing again but I think froyo is doing something to preserve battery life. Idle battery life pretty much doubled for me after upgrading to froyo.

Re: Battery Life After Official Froyo OTA Update on 8/2
 

When I get home ill probably just hard reset and do some 1 by 1 app adding to see if I can tell what it is.

Re: Battery Life is a beast on Netarchy rooted froyo
 

I think Sprint may have addressed the issue with the immediate drop to 90%. I too noticed that even on the rooted pre-release my phone gradually declined to 90% instead of the typical instant drop to 90%.

Re: Battery Life After Official Froyo OTA Update on 8/2
 

Anyone that has the battery drain issue should look at this,it solved my battery drain issue with my"Leaked" 2.2 ROM

look at thread # 427.

Re: Battery Life After Official Froyo OTA Update on 8/2
 

Yea thats what I used to fix my leaked rom.. but it doesnt seem to work on this new ota. There has to be something that im running thats keeping the phone awake.

Re: Battery Life After Official Froyo OTA Update on 8/2
 

My battery life has increase by 10-15 percent since the update yesterday. I even have the auto sync and background data running just to see the difference and still have a significant increase in battery life. I am truly impressed with the change.

Re: Battery Life After Official Froyo OTA Update on 8/2
 

I have having bettery issues as well. My phone seems to be dipping from 100% to the 80% in mere minutes. Its gotta be an app running the background that is doing this, I just cant figure out which one.

Re: Battery Life After Official Froyo OTA Update on 8/2
 

I had the stock latest version software, and LED Light, did the 2.2 8-3-10 upgrade and it works fine for me.

EDIT: While LED Light functionally works, it runs constantly in the background, causing the Up Time and Awake Time to be the same.

Unininstalled it, and the problem of dual Up and Awake time went away.

The new onboard Flashlight works just as good if not better than LED light, with the exception of having to press once for the App Icon, then again to turn on the LED, but now you have three different brightness levels with the new program.

Re: Battery Life After Official Froyo OTA Update on 8/2
 

System panel is a great app to help figure out what background app is constantly running.

New flashlight, well not new but a great version is Led Desire light. One of the best flash lights on the market if you ask me and its free.

Re: Battery Life is a beast on Netarchy rooted froyo
 

I was thinking that too but I now have had sum normal usage and been unplugged since 6:55 and I still have 90 something left, after a few texts, a 20 min fone call, web browsing, I normally never would of had that! I'm not sure how to post the screen cap so I hope you can see it!

Re: Battery Life After Official Froyo OTA Update on 8/2
 

I looked at that LED Desire program, and it just had way too much stuff for me. I simply need an app or widget on my homescreen, that I tap to turn on and tap to turn off the light.

I found that in the LED Light App.

I have no need to send morse code etc., that the LED Desire app offers, so if your looking for basic LED, then LED Light is your app.

Yea and heat issues to worst then it was
