i bought my hero last week and ive been playing with it and installing alot of apps and such along with different roms testing the speed and overall battery life. right now im running fresh 1.1 rom and several apps from the market. the thing runs really fast and the battery life is amazing. it went all day yesterday and all last night and just now its at 29%. and this is with moderate use!
i do have a question though, how much free ram is normal for this phone. i see with all of my apps and such i have about 75-85% free when i use task killer. and yes my apps are on the sd!
also what would you guys recommend for a extended battery. i don't want a huge one that will require another back cover. just one that's a higher capacity.
edit: just a FYI, don't install the antivirus app from the market, it is a HUGE battery killer. i know we don't need the app but i wanted to test it out.

first read this. as far as your memory goes istalling and testing all those apps have you cleared out your cache recently? As even though the apps are on the SD they still store the cache on internal.
I'll second nixing the task killer. I was a skeptic at first, but I sacked the task killer and took note over the next two days. Much better WITHOUT the task killer.

Yup. Very happy with speed and reliability. Can't imagine why I ever needed a task killer.
Battery is way better than I expected. I play with my hero all day, browser internet, youtube watch, check email, download apps. The phone still has 20% more battery. And the memory control is good. I used to use taskkiller. But now I don't use it anymore. I don't turn off hero for 3 or 4 days, app runs quickly. But the Android system has to improve. It could be better.
Same here. Battery life is pretty good. Quit using a task killer and the phone is running great. If you have Astro or ES File Explorer installed they have a task manager/killer built in that you can use if you REALLY think you need to kill something.
Battery. There is a thread in the Sprint HTC Hero section on androidforums about a replacement battery that is higher capacity but fits with the stock battery cover. Everybody seems to love it.
It won't let me post a link to it, but you can go to androidforums.com and go to the Sprint HTC Hero section and search for Mugen Battery 1800mAh.

Bro, this is Linux, not windows. An anti-virus would just be a waste of time
my battery life blows. i don't have many apps running either. wake up at 7am and it's dead by around 10pm with not too much use.
GMail in use
GV set to 5m updates
DealDroid set to 15m updates
WeatherBug app in the background (same battery span with TWC or other weather widgets/apps)
Bloo app in background sometimes

Hey guys, If you have been involved in this community for a while then you well know how developers feel about task killers. Many such as Cyanogen have spoken out saying they are useless and not good for the phone. Heck, even Google released a blog about how Android works.
http://androinica.com/2010/05/07/google-and-cyanogen-comments-imply-task-killermanager-apps-are-pointless/
So, is the stock task killer build into the J16 update going to have the same negative effect? I am wholly against task killers. I work in the industry and every time I am helping a customer or selling a phone I make sure they know the negative impact these have on a phone. But i want to know what you guys think.
Dev doesn't have problem with Task manger per se, they have problem with the "auto-kill" ability of some of the task manager in the Market.
I personally think JI6 task manager is cleanly done. It even tells you the CPU usage, so you can just kill of the "trouble" APP. It also doesn't show any of the system apps so, making it impossible to screw things up.
Plus, it's got other information that are helpful as well.

True, it is that System app that can mess with crap. But what about apps that share processes with other apps?
Task managers are total crapware...well for the most part...auto killers are the plage avoid them...the bully in task manager seems to be okay for only one thing to kill an app that had locked up or needs to be reset...other than that its a waste of space and battery drain if you run the widget.

All the widget does is tell you how many active apps are running. The task manager is welcome seeing as how even some built in apps don't allow you yo cleanly exit them and Android apps tend to consume large amounts of RAM.

I think I've made it clear on my stance, but I will say the task manager on JI6 seems fine. The fact that it shows the CPU usage is the key part. And like others have said, it does not show system apps... just don't end the obvious ones that are syncing or widgets...
Well after running battery graph with and without the widget running...the widget takes 1% from the battery every 10 mins it runs...I liked the factor of seeing what was running in the bg but too much battery use on my stock battery...got a 3300 on the way...might use more widgets and apps after that but with this weak battery not going to use anything that eats battery away....btw running b 1.7 with voodoo lagfix

Personally I don't mind the Task manager. I had "Where" go bonkers on me and I didn't realize it. It was running 80% and my phone started to get hot. I killed the app and it returned to normal.
Never mind the fact that I started "Where" probably 15-20minutes earlier and it ate nearly 20% of my battery in the period with the screen off and sitting at the home screen.
Apps can go rogue and in my opinion thats when they should be used not because it gives you a false since of your saving battery power or to make room for other apps.

Nevermind responded when I didn't need to.
It's not a ' task manager ' as they call it, its a process manager... in the original vibrant Rom JFD , if you create a shortcut for the activity, 'running services' , it links to the same service... I don't use it but don't mind it as long as they never add an auto kill feature to it... I think it will also stop new users from getting app/task manager crap_ware from the market...
I like it and i think its better than the task killer in the market,
At least it is not suggesting killing everything but showing how much CPU the app is using.
For sure, i won't put that stupid ugly widget in the desktop as it is really useless

Hey, I know that the apps are consuming the battery life. But mine is not like that.
Hi,
i have been using my android phone for about 3 months now, good experiences
i reboot the system quite oftern (personal preference)
however what i have noticed is that when i first boot up and use for about a few weeks the phone is VERY fast and snappy, after that doing things such as updating friendStream cause the phone to freeze for about 10-15 Seconds. i have a few apps installed, not an excessive amount.
Quick System Info - task killer
GPS/ location = OFF
WiFi = ON
GSM Only - save battery
any ideas?
i understand the Wildfire is slow hardware, but why would it be fast to start?
Thanks
Dude don't use task killers. It's not Windows Phone times when task killers where a way to go. Android has a biult in task killer which kills apps on his own decision. A app that YOU killed on YOUR task killer will start itself. So with task killing you not only load the proccesor a LOT but you make the system eat more RAM because it's starting apps.
Task killers increase battery drainage, and overall slower performance.
Well, I took some advice and am now running a 7day no task-killer test.
Day 2 so far and I don't even notice the difference ._.
Yeah don't use task killers, no point. If you must, just get AutoKiller from the market so android kills background apps a little faster. (Only if you have root) set it to moderate or strict.
Another idea is to get a different launcher app off the market. Sense is a big memory hog.
(Off topic alert!)
You sound a bit like my brother... he was asking me tonight why his Wildfire is so laggy now and my x10 is so snappy...
dont use task killers, never... tell just eat battery and etc... use this http://forum.xda-developers.com/showthread.php?t=1111145
Thanks for all the advice, going to uninstall the task killer in a few mins.
as for the launcher i am using LauncherProPlus - even that lags sometimes, sure that shouldnt happen. any advice about overclock?
RAM usage stays below 40% (usually)
CPU averages around 80% (100% in apps such as Drop)
Thanks again

The diffrence will be noticed young padawan *read in yoda's voice*
Besides, if there is no difference is using and not using an app, IMO, it is better to not use it in the first place.
I am now on 25 hours without a charge and still have 65% battery left. Previously I couldn't make it through the day without hooking up the umbilical cord of life. I used to clear apps regularly with the stock task manager but would start out with 150MB free after boot and by the end of the day could not get better than 80MB free. Everyone was crying memory leaks. These are NOT memory leaks but errant programs that cache behind trhe scenes draining your battery and stealing resources. They are also immune to the stock task killer.
I found these bad bad apps by installing Memory Booster Lite from the market. After getting a 0 applications closed I went into the Task Killer in Memory Booster and found a bunch of apps loaded into memory still! Things like Google + hogging 28 MB of memory! There was Amazon Appstore, Maps, Facebook, Beatiful Widgets, Email, Telenav, Netflix, logsprovider....all immune to the stock task killer and slowly eating memory during the day as they load. I killed all the ones I recognized (no com.XXXX stuff) and then checked back in a few minutes to see what would reload. Google +, Beautiful Widgets, Facebook, Maps, and others would reload. Using the paid version of Titanium backup I froze apps like Google +, Maps, Netflix, and others that I don't use daily. You can use other apps for this like Autostarts. I deleted apps that are not worth my memory and battery power. I also set all syncs to manual and keep the display down as low as I need to. The results were tripling my battery life. I also stay on Wifi as much as possible and as soon as I get off XDA App, Tapatalk or any browser clear it with the stock task killer. I always have about 140 MB free now.
Your mileage may vary. The display is the biggest battery killer so if your a gamer, or spend hours reading, don't expect a lot of improvement from this but you will see some. I hope this helps battery life and memory leak myths for some of you.

I'm not trolling, and you do have great suggestions here. I just wish there were some easy way to get an entire day of full use without having to get an extended battery while using the epic to its full potential. I like autosync, adecently lit screen, and my range of Widgets which I use daily. Too bad I can't go more than 16 hours with everything on. I have tried at one point most of your suggestions, and it did greatly improve battery life. I suggest anyone at least give it a shot and then slowly turn back on the things they must have, like gmail sync or haptic feedback.

Blankrubber, this is a good place to add on to what I just found. The key is to see what else is running that is immune to the stock task killer. I never knew how much Google + and Maps were killing my battery. I got rid of my extended battery long ago but now I am sill amazed. 29 hours and 52% left. But the key when you say using it fully is limiting display time and intensity. No matter what that is the biggest drain so if you are glued to your phone for over 4 hours it will always be tough to make it last. Phones that used to be just phones could go days without charge. Now they are little computers. Think...laptops only go about 2 hours runtime without a charge and those batteries are a lot bigger.
I use Bloat Freezer myself. It shows whatever is running in the background highlighted in gray. Google+,Maps, the others Kenny mentioned are the usual suspects. Doing what Kenny said will help out for sure. Yes, its annoying we have to do this to extend battery life but some apps are always at work. Memory Booster is pretty good. Viper baked it in a ROM a while back. Its definately worth checking out

If something is just sitting in memory why would that have any effect on battery life? It should actually improve your battery life cuz then it just loads the app from memory and not a full re open of the app. Now if your saying that these questionable apps are just running processes then yes that would have an effect on battery as it is just sitting there doing something. But back to the memory side of this. Memory is used in all devices to take some of the load off the processor to make it load faster. It is there for a reason every device would not use memory if it was not efficient at loading apps and saving battery.
But if you only use the app once a week or so why waste those resources or the initial load time. If it sits in memory and another app needs that memory the processor uses more power and battery swapping apps in and out of memory needlessly. My phone is super fast and running 32 hours with 46% left. I can't put up a better argument than those results. Memory swapping is bad on battery it seems.

I've been around the Android platform for more than 3 years. I've pretty much read all google has shared with us (the Military) for application development and I do agree that there are dormit services that hog up your memory / battery even when your not using the phone.
I agree with this dev and his tool: http://andrs.w3pla.net/autokiller/details
I think that he nailed it when he found out how did Android manage memory and the determination it takes in order to "kill" what you don't use.
Now... Do you care to share what you know about the subject that we don't, in stead of just coming bashing and leaving?
This is a forum, we are more than open to debates here.

Nice. That was my issue though is that some of these memory/battery killers don't show up in the launcher's task killers. Google + and Maps never show up and get stopped and continue to kill the battery getting data behind the scenes because Google wrote them in that way. It is important to at least check if you have bad battery life what else is running with a good task killer like Memory Booster Lite.
i think the best solution for battery life is autokiller, v6 script and titanium..the stock gingerbread task manager aka (the running services in settings) isn't that great...when i was on eg22, i noticed it displayed the wrong amount of ram left and didn't display every single app running in the background..autokiller is able to see every single app running in the background but never kill the programs with (com.google and android.process)...I only kills apps i use like engadget and pulse..when u exit these with back button, they always stay in the background and use autokiller to make sure it's completely killed...never set any task killer to autokill apps, that will drain your battery faster...and they are some annoying 3rd party apps that always run in the background since they are not coded well (imo)..for example, i froze the script manager with titanium after i implemented the v6 script because it kept restarting itself all the time..i suggest people follow RandomKing's tutorial on how to extend battery life, it helped a lot..http://forum.xda-developers.com/showthread.php?t=1106524...i constantly have 150 to 200 ram free with im not running any apps..im on eco5 aosp rom with eco5 (eg22 and eh06 are not stable enough for me)
To be honest, I think you're overestimating the effect these task killers are having on your phone.
Your graph looks very similar to mine when I'm using it moderately, and I haven't installed any task killers. (And, yes, I've got the same Maps, Google+, etc apps on my phone). The only changes I've made are:
- Turning my screen brightness all the way down.
- Having very few non-push syncs.
Today I'll be using my phone a lot as a camera, but I'll try to remember to leave it off the charger one day this week so that I have a power graph that lasts longer than 18 hours.
Android task killers improve your phone's performance while also boosting battery life—or at least that's the much-debated promise. Here's a look at how task killers actually work, when you should (or shouldn't) use them, and what you can do instead.
A task killer is an app from which you can (sometimes automatically) force other apps to quit, the hope being that the fewer apps you have running in the background, the better your Android's performance and battery life will be. Not everyone agrees with this premise, though. The argument about whether task killers are effective rages all over the internet: Android forums are full of threads with constant bickering and conflicting anecdotal experience, making it difficult for most users to make sense of the situation.
Below, I'm going to dig into the truth about Android task killers: that apart from maybe some older phones, Android manages tasks fairly well on its own, and how task killers present quite a few problems. I'll also take a look at the rare occasions when they're useful, and offer some alternatives you should try to improve your phone's performance and battery-life quirks.
Before we dive in, here's a quick overview of how Android handles process management by default.
How Android Manages Processes
In Android, processes and Applications are two different things. An app can stay "running" in the background without any processes eating up your phone's resources. Android keeps the app in its memory so it launches more quickly and returns to its prior state. When your phone runs out of memory, Android will automatically start killing tasks on its own, starting with ones that you haven't used in awhile.
The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a good thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck.
Why Task Killers Are (Usually) Bad News
Apps like Advanced Task Killer, the most po****r task killer in the Market, act on the incorrect assumption that freeing up memory on an Android device is a good thing. When launched, it presents you with a list of "running" apps and the option to kill as many as you want. You can also hit the Menu button to access a more detailed "Services" view, that lists exactly which parts of each application are "running", how much memory they take up, and how much free memory is available on your phone. This set-up implies that the goal of killing these apps is to free up memory. Nowhere on the list does it mention the number of CPU cycles each app is consuming, only the memory you'll free by killing it. As we've learned, full memory is not a bad thing—we want to watch out for the CPU, the resource that actually slows down your phone and drains your battery life.
Thus, killing all but the essential apps (or telling Android to kill apps more aggressively with the "autokill" feature) is generally unnecessary. Furthermore, it's actually possible that this will worsen your phone's performance and battery life. Whether you're manually killing apps all the time or telling the task killer to aggressively remove apps from your memory, you're actually using CPU cycles when you otherwise wouldn't—killing apps that aren't doing anything in the first place.
In fact, some of the processes related to those apps will actually start right back up, further draining your CPU. If they don't, killing those processes can cause other sorts of problems—alarms don't go off, you don't receive text messages, or other related apps may force close without warning. All in all, you're usually better off letting your phone work as intended—especially if you're more of a casual user. In these instances, a task killer causes more problems than it solves.
What You Should Do Instead
That said, not all apps are created equal. Many of you have used task killers in the past and actually found that after freeing up memory, your phone works a bit better. It's more likely that this is because you've killed a bad app—one that was poorly coded, and (for example) keeps trying to connect to the internet even when it shouldn't. Any performance increase you experience is more likely because you killed the right app, not because you freed up loads of memory (or, in many cases, it's just placebo). Instead of killing all those apps, find out which ones are actually causing the problems. If you really know what you're doing, you may benefit from using a task killer to stop the one or two inefficient-but-loved apps on your phone.
Note, however, that this is still a contested notion. A lot of developers (including ROM builder extraordinaire, Cyanogen) will not even look at your bug reports if you're using a task killer. In this humble blogger's opinion, your best bet is to stay away from regular task killer usage entirely. If you absolutely have to have that one battery-killing app on your phone, though, kill away—just be aware that when you experience a recurring Android bug later on, the task killer may be at fault. Of course, you can just stop using it to determine whether that is or isn't the case.
With task killers firmly in the better-off-without box, there are still a number of other things you can do to fill the void, improving your performance and battery life
Watch for Runaway Processes: Previously mentioned Watchdog is a slightly different kind of task killer, in the sense that instead of telling you your phone's out of memory and it's time to go on a task killing spree, it alerts you when the occasional app starts eating up CPU for no reason. You can then kill the app with Watchdog and get on with your day (though honestly, at that point, I usually just reboot my phone). If it happens often with the same app, however, you may want to move on to the next step.
Uninstall Bad Apps: Worse than the occasional, one-time runaway app is the poorly coded, always-eating-CPU app. If you find (with Watchdog or through some other method) that a particular app seems to drain CPU and battery life whenever it's running, confirm your suspicions by uninstalling it and seeing what happens. If an app is causing problems on your phone, you're probably better off without it.
Root Your Phone: We advocate rooting Android devices a lot at Lifehacker, but that's because it really is as useful as everyone says it is. You can over- and underclock your phone with SetCPU, install custom ROMs that noticeably improve performance and battery life, and use the ever-useful, crapware-thwarting Autostarts utility to stop apps from starting up on your phone in the first place. Honestly, with one-click rooting apps like previously mentioned Universal Androot available for most phones, rooting only takes a few minutes to do, and you'll be much happier for it.
Update: Many of you also mentioned the root-only app Titanium Backup, which will help you get rid of the pre-installed crapware that comes on most phones, which are one of the worst offenders of phone lag. Thanks to all of you that sent this in!
Seriously, Use the Power Control Widget: This may sound ridiculously obvious, but if you aren't already using some form of the Power Control widget, you should. The things that drain the most battery on any smartphone are Wi-Fi, Bluetooth, GPS, and your screen. Turn them off when you don't need them and you'll find that you can eke out considerably more battery life.
Charge Your Phone: Even more obvious yet rarely heeded advice: Charge your phone often. This isn't as hard as it sounds for most people. While you're sometimes stuck going out for 14 hours with no place to charge your phone, the majority of us spend our days in our homes, our offices, and other places rife with electrical outlets. Buy a few extra chargers and place them strategically around your home, car, and office. Whenever you're sitting around at home or working away at your desk, you can use that time to dock your phone and give it some extra juice without worrying about battery or performance drains. Before I upgraded to Android 2.2, my battery life was pretty awful, but just having a charger in my car and next to my computer made a huge difference in how often I got the dreaded "low battery" message.
Task managers are a controversial subject in Android-land. We've done our research and this is what we came up with, but we're always keen to hear how similar or different your experience is, so share with us in the comments.

Exelent post. I'll uninstall my task killer now, and I'll try Watchdog app to see the the difference on performance and battery life. For example, I have Navigon installed, but always closed, I'm using sometimes. Is that app draining battery when closed?

Watchdog will tell you how much of your cpu a certain app is using. So i believe (pls correct me if i'm wrong) that that would give an indication if it is actually playing a part in draining your battery.
