OK, my battery lasts 4 times longer now. No joke!

[anewday]

The topic title should be changed. :icon_eek:

 

[maladroid]

lol you guys are hilarious with your "kind sir"s and "good day sir"s; reminds me of my 60 yr old dad having it out with a telemarketer haha

I think we all knew, without having to ask OP or call him on it, that 4 days was an exaggeration. True, he didn't have to add "No joke!" to it, and I think that's what everyone's taking issue with, but still, it's not like his post said that he physically opened his droid with tools and performed key modifications to the circuitboard or something crazy like that. If you read the OP and see that all this guy did was install a market app, that should be enough of a flag for any reasonable person here to know he's being hyperbolic, or at least, that his statement was just flat out inaccurate. That being said, I would bet money that anyone who decided to press him on the 4x issue already knew the answer (c'mon) to their own question without needing to egg OP on, but it's nice to know that no unqualified statements shall go without the requisite onslaught of nitpicking and disdain.

On the bright side, I think it's safe to say that the OP will definitely choose his thread titles more wisely in the future, right s54?

Now getting down to actual substance: Johnly makes a good point, in that what these programs are designed to do is to save your phone from draining during times when your phone is idle. As this is the case, the more someone leaves their phone in an idle state, the bigger improvement they will see with these programs. BUT, just because you have Apollo or JuiceDefender or anything like that, doesn't mean you'll be able to play games for 9 hrs straight on full brightness or browse full websites for hours on end - these programs do nothing to help with the actual "in use" aspect of battery consumption.

If you want to improve how your battery performs under the actual pressure of usage, you can take certain steps (root users only), such as choosing a low voltage kernel, running in "conservative" rather than "on demand" mode (doesn't hinder performance as much as it sounds like, give it a try!), or simply switching to a slower processor speed.

I personally run at 600mhz, but with JIT enabled. That way, I get 7.3 mflops out of linpack, which is respectable (about what you'd get running 850mhz without jit), but I'm not sacrificing battery life for this performance boost the way i would be if i ramped up the processor. Also, the 600mhz I run at is a lower voltage setting than stock 550mhz, because I'm using P3Droid's ultra low voltage kernel. I can tell you guys that yes, this does improve my battery life DURING ACTUAL USE of the phone, but i wouldn't call it any more than a 15-20% improvement over complete stock. If you're currently running at 1ghz or above though, give it a try for one day, you'll notice a big difference; however, I doubt anyone currently running at that speed is very concerned with battery life in the first place..

In terms of battery usage while in sleep mode, I do hit "kill all" before sleeping the droid just as a compulsion, but I think the real big saver for me is setting my SetCPU sleep profile to 250mhz, powersave scaling. If I go to bed without plugging my phone in, there's about a 50/50 chance that I'll wake up to the same percentage 7or 8 hrs later as what I had left when I went to bed. If not, it will only be down by 10%, but never more than that. This remains true even if i leave gps and wifi on.

Johnly actually doesn't make a point and here is why. By design linux store all it can in memory. For personal computing this is a great design. The most frequently used things are kept in memory and space is created when needed. Unfortunately Android employs this same memory management design. The problem lies in the fact that memory is a massive power hog. The more it's used the more power it uses. So just storing dormant apps in memory so they can be brought to the foreground faster is draining your battery at an exponentially higher rate than if those dormant apps are cleared from memory as soon as they are no longer needed. Obviously this makes no difference on a PC since it's plugged into the wall. This is THE reason why Apollo works and why it works better than other task killers. The only people who will not benefit from this app are people that use their Droid from unplug until battery death without the phone ever going to sleep.

 

[xliderider]

I installed the exact app that you mentioned, when to settings and chose to auto kill apps after one min after screen turns off. I tried to add apps to the ignore list, but no apps were there for me to choose from. So what do i do? how do i add them to the ignore list if i cant see them listed? thanks

Open your app drawer and open the app that you want to place on ignore. Press Home, open Apollo Task Killer, the app should be in the list. Repeat as needed.

 

[slinky]

Apollo caused me some problems. All task managers will "save" the battery in the same way. I've found that shutting the phone off completely when not in use practically doubled my battery...

 

[TuBitMittens]

Wait is apollo task killer and advanced task killer the same?? I searched apolla task killer in the market and got no results but advanced task killer is developed by apollo, im so confused..

no, wo different ones. I had advanced on my phone, and deleted yesterday and dowloaded the apollo one. I can tell you, so much of a difference. I also did what someone suggested about changing some seting such as the brghtness and stuff, and it all reall worked.

But wait there is no app actually CALLED "Apollo Task Killer" right?? Its just advanced task killer free and the developer is apollo, correct? Because thats what im using. I wouldnt be surprised if there was some kind of copyright issue with the names going on right now.

I guess I reading more than was there into his comment about "keeping the screen lit for 24 hrs". Let me clarify I guess what I will call my point, then, which I'm pretty sure is valid.

Say for instance you wanna play Homerun Battle. Great. So you go ahead and kill all apps, and load it up. Aside from the apps just restarting themselves in the background, which is an issue I'm not going to touch, it's not like programs like Apollo or JuiceDefender are actively doing anything to help save your battery while you are playing the game. It's not like they're making the game run more efficiently or the screen take up less power, or the processor use any less juice. Playing the game will devour your battery just as bad with these programs installed then without. That's the point I was referring to - the improvements anyone experiences with these programs will largely be the result of a more efficient idle state, and not some strange magic that these programs to do save your battery while you power-use your Droid.

I don't think anything I said up there actually conflicts with what you just said. In fact, you wrote, "The only people who will not benefit from this app are people that use their Droid from unplug until battery death without the phone ever going to sleep."

and I think that speaks to my (Johnly's?) point precisely. That sentence basically says if you never put your phone in an idle state, these programs won't do anything for you.

I know in my posts I was thinking these two were the same name, but the two I was referring to are Advanced Task Killer (Apollo) and Advanced Task Manager (blue settings icon)

Well the auto task killer will help while you're playing games if there are tasks to be killed in the background. But no, it does not make a single running instance more efficient in any way... and I don't think it was ever implied that it would do that. Obviously a task killer won't make a task that isn't being killed use less battery. So while it is true, I don't know why that point would have ever been brought up in this thread.

The Apollo app specifically targets apps while the phone is sleeping. Other task killers target dormant apps while the run is in use. So yes, task killers will help the 24/7 "screen on" user. But those users are burning through battery so quickly they may not even notice a 20 minute gain or whatever it would be.


maladroid i'm not really replying to you here... but not only was this irrelevant point brought up but it was used as a point to unnecessarily attack the OP.

beautiful widgets and battery

quick sort of off topic question

Is beautiful widgets a memory hog and battery drainer?
I was using that, and the google news widget but in deciding on how to maximize my battery life and everything I decided to uninstall beautiful widgets and just use the google widget as news AND weather.
I would definitely reinstall it, if i had some solid info on beautiful widgets

 

[maladroid]

Well, my issue is, people shouldn't put too much stock into the accuracy of people touting x% battery increase due to these types of apps without considering the ratio of idle to in-use that achieved this improvement %. If you use your phone constantly, don't expect to see much of an improvement, but if you only awaken it periodically to do a menial task, you can possibly experience a vast improvement in battery life, because your phone won't require as much juice in its idle state with the help of these apps.

When people don't understand this, the result is an ensuing pointless argument about how well these battery savers are actually working, why people aren't getting same results, whether the OP was right or wrong, etc.

Task killer apps are not needed with android operating system. Yes there are allot of things running in the background; however, their not using resources like windows would. Task killer apps will stop more than emails from updating and it will slow applications because they have been turned off. If you have extra time and like the feeling of managing the apps, and you want to constantly close programs because it's just killing you, go ahead. The droid runs stock and 385 minutes full blast (deja vu) and 270 hours standby time (OVER TEN DAYS) stock (deja vu).
Did you get my point? Motorola.com THE PHONE WILL STAND BY 10 DAYS!
that's pretty good. Speak for yourself please. sorry the weather is crappy over there.

Dude. You're a troll. You have no idea what you're talking about. You're quoting specs as if they apply to real world usage. And you think somehow apps can magically reside in volatile memory space without using electricity. Hm... I wasn't aware Android had magical powers. (Well, I was aware Android was magical but it doesn't magically use electricity-less memory.) The Androids memory is volatile memory. That means in order to put something in memory it needs an additional constant electrical charge to keep it there. That Drains the battery. The more things that require a constant charge from the battery the quicker the battery Drains.

READ CAREFULLY> IT DOES NOT MATTER IF THE APP IS BEING USED. IF IT IS IN MEMORY IT IS USING THE SAME AMOUNT OF BATTERY FROM MEMORY WHETHER IT IS USED OR NOT.

Now stop trolling this thread with mis-information.

I forgot, you are an advanced linux developer. Wait? You are? Then you of all people should know that android will politely close apps for your game to run most efficiently, and walla, NO WORRIES, lol. I am considering posting some links to other forums so this thread can get MORE info, but here on droid forums, it just isn't needed, as those who know how the system operates will continue to post (I am not trying to be a punk, but I think there is more to consider here dude)
