you don't have to believe it. those are real facts. go into settings - apps and see how many running apps you have. now go to cached apps and see there, how many apps there are. you see? nearly 50% of those apps discovered by you in the processes are apps that you didn't opened ever but they are still opened and running. why? because that's how linux manages its resources. instead of having free ram for no use (what's the point of having 14gb of ram when you only use 1gb), linux fills all the ram blocks with useful apps or apps that you are running frequently so that when you call that app, it will bring it on the screen almost instantly. this my friend, is called multitasking.

and no, you are wrong. if you use a task killer killing the apps every 10 minutes, the cycles the whole system does - opening again apps and caching them, task killer closing them - results in much more functions done by CPU => more battery spent. even if you say that the battery life its the same, you are wrong. when using a task killer IT MIGHT drain your battery with 0.1% per hour. it's not that much, but IT EXIST.

oh and yeah, one thing: android has its own task killer. that's why you don't need one app to kill your other apps. because android its doing it by itself. if you don't believe me, strip down one kernel, open the init.rc file and find the values for task killer.

I'm using task menager when is needed, and also I'm using custom system memory tweaks, it makes my phone running faster and smoother :) some apps knows to stuck and they keep the phone from entering deep sleep, and that drains the battery, so if you know what are you doing use task menager and customize when what apps the system should kill ;)

ATTEMPTING THIS WILL VOID YOUR WARRANTY AND COULD KILL YOUR PRECIOUS PHONE

First and foremost props to Adam Outler for being the genius behind UnbrickableMod. Adam you rock, buddy.

Disclaimer: This worked for my totally bricked/unresponsive Samsung Mesmerize, it may or may not work for you.

THINGS YOU NEED:

1. Conductive pen from Radio Shack

2. Sewing needle

STEPS:

1. First, take a look at Adam's thread where he explains the minor hardware change that needs to happen to make this thing work. Read it, and fully understand the steps he takes that is basically just moving down and either replacing or re-soldering a teeny-tiny jumper. NOTE: The link's instructions are for the Fascinate, which has identical hardware http://xdaforums.com/showthread.php?t=1288093

2. Go to Radio Shack or online and buy a conductive pen (this is what saved the day for me); and acquire a sewing needle.

3. Watch a Youtube video on how to safely dissassemble your phone. Realize how freaking small everything is, and get a magnifying glass if you need one. I have good vision and didn't need magnification, but you might.

4. Once your phone is dissassembled, locate the resistor pad that needs to move, and carefully use the needle to pry it out of place. Mine snapped out and shot across the room... But this wasn't a big deal because I didn't need it anymore anyway. Use the needle to scratch away any remaining adhesive that held that pad in place. Magnification may be needed.

5. Shake your new conductive pen well and play around with it first to get a feeling for it... Next make a dot of conductive ink where the resistor should now be placed... This will likely spread a lot further than you want it to... but that's ok. Give the conductive ink about 5 minutes to start to set in place.

6. Using that trusty sewing needle, start to scratch away any conductive ink where it does not belong. This is extremely important and the key to getting this to work right. We are "creating art by erasing" here, and the great thing is... if you mess up you can just wipe or scratch away your mistake. I repeated this step a couple times until I had a nice thick (but not too thick) connection that did not in anyway connect to anything else on the board. I then used some alcohol on the end of a toothpick to wipe away any silver residue that was left behind.

7. I gave my phone an hour to full set before I put it back together....

This worked on my first try. I Ran Adam's sweet Ultilmate Resurrector and bam... Download mode.

BTW: I waited 3 months to post this, because I wanted to make sure that this method would work long term and so far it has. Again a big thanks to Adam for saving the day... and taking the fear out of flashing our Samsung's.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] RipplingHurst:
Hi,

Can somebody help me pointing out ROMS where the HDMI out functionality works on the 7.7? I've seen posts where people claim only stock rom would do that, but this seems to be not true for every other Android device I have. I have used CM10 on the Tab 10.1 (CM10 = NOT BLOODY STOCK) and HDMI works wonders, it's great to play digital quality files with my DA converter. But I'd like to use my 7.7.

Any tips? The one I'm using now doesn't work, was the first ICS issued months ago. I thought it would be stockish...now do I have to go back to honeycomb? Sure I hope not.

Any pointers?

Thanks!

[Desire HD Q&A, Help & Troubleshooting] HukkaHD:
Hi!

I installed blackout ICS incredible in my DHD. Everything went well but I wanted to calibrate my battery.

So I downloaded Battery Calibration by NeMa from Google play. Before calibration my batterylife was about 12-24h depending on my use.

Now after the calibration my batterylife is about 5h!! And the same usage as I have always had, couple of calls, net surfing and maybe a little of Angry Birds and spotify.

Did I do something wrong or is my battery dead? My DHD is about 2 years old.
[Desire HD Q&A, Help & Troubleshooting] bananagranola:
According to Google calibrating your battery (erasing your battery stats) doesn't actually do anything, so it shouldn't have made your battery life shorter. You could install BetterBatteryStats from a thread here on XDA to see if something else is eating your battery. Look at alarms and wakelocks.
[Desire HD Q&A, Help & Troubleshooting] HukkaHD:
Ok, thanks. I installed the BBS and I'll tell the alarms and wakelocks here if I don't find anything funny about them... :p
[Desire HD Q&A, Help & Troubleshooting] kingofnice:
bananagranola is right.

- hit my thanks button if i helped you -
[Desire HD Q&A, Help & Troubleshooting] xxkid123:
calibrating your battery basically tells your OS how much batter it has or doesn't have. IF you flash a rom at less than 100% battery, then the max amount of battery your OS thinks it has might be different from how much your phone actually has. Sometimes this can affect battery life.

The other thing is, did you calibrate at 100%, then unplug immediately? If not, that might trick your OS into burning your battery so quickly.

Otherwise, 12hrs to 24 hours is super amazing, I'm a semi heavy user, and I'll only be able to get 12-14 hours of semi serious use (8 hours standby, 2 hours on off usage, some of that at 100% brightness when i'm outside, and lots of music), end of that I have only 32% left. 24 is pretty amazing, I wouldn't be complaining :laugh:
[Desire HD Q&A, Help & Troubleshooting] kingofnice:

[Desire HD Q&A, Help & Troubleshooting] HukkaHD:
Ok, so I have had today the BBS running on the background. I tried one thing in afternoon, I switched of Wifi. Wifi was off about 3h and when I came back to home I switched wifi back to on. I have still 70% battery!! and about 12h without charging.

BBS alarms:

android, wakeups:83 (Is this much?)

com.google.android.gsf, wakeups:56

com.android.settings, wakeups:13

and the rest of them is under 10

BBS Kernel Wakelock:

wlan_rx_wake: 14m18s

PowerManagerService: 10m57s

and rest is under 4mins

BBS Partial Wakelocks:

AudioOut_3: 3min16s

Twitter sync: 1m56s

BBS Other:

Deep Sleep is about 10.5h

Wifi On/running is about 6h

Is there something wrong or is there something that uses too much battery? Could the battery be "damaged" due it's about 2 years old now?

Sorry for stupid questions but I find it very annoying that sometimes battery life is 5h and sometimes it's way more than 12h with same usage.
[Desire HD Q&A, Help & Troubleshooting] bananagranola:
What you've got looks fine (which makes sense, since you had good battery life this time). Keep BBS installed. If/when battery life starts tanking, take a look at BBS and see if anything else pops up. If you've got more questions then feel free to post again here.

[Android General] Gezetah:
I've never used those programs, I like to use what the phones have by default (:

But is good to know anyways :p
[Android General] xxkid123:
I agree with that...to an extent

Auto killing apps is plain stupid, but I do believe in killing certain apps. In a perfect world heavy apps would just be uninstalled, but plenty of useful apps without good replacements are fairly heavy, and it helps to kill them. E.g. after exiting a game I will kill it because its hogging up valuable ram by running in the background, while still using he same resources it uses at the forefront.

I understand that android, and Linux should manage ram well, but more often then not some app is just out there slowing my phone down. Even an hour later of not using that app, it'll still be in the background using up a lot of CPU and ram I don't have (more importantly battery). Android is great at managing smaller apps, but in my experience, it sucks at doing the same for larger apps.
[Android General] dxppxd:
I don't use automatic task killers, those that are constantly running, but i do kill unused tasks and apps with no reason to be still running. Google services is a common example. It will launch at boot and keep running peemanently, even if you never launch a google app, google services is running, why?

A lot of apps, mostly the free ones, get revenue by reporting anonymous usage statistics (not so anonymous in some cases). So they stick a running service even if the app is never launched again (sometimes even if it isn't launched in the first place).

To sum up, killing everything is bad, but leaving everything to run free can also decrease performance. This can be observed on an android device that has been running for a long time, versus an android device that's just been reset.
[Android General] Markuzy:
some unused tasks will repeatedly rerun even if killed.

This will further decrease battery life and affect performance as resources are needed to keep restarting it.

The best way is to ignore if it takes a small portion of resources or to uninstall the app. Rooted users may disable the triggers via certain apps.

[Android General] cybervibin:

[Android General] 1ceb0x:
let me tell you something about google services...

when you installed your rom, you had to check two options from google services - location and another one.

if you are on stock, those options are available in settings also.

the google services are needed (you are running a google os, right?) because without it, the location feature will not work, the play store will give you headaches and not to mention, google now that needs that service like water.

if you kill that process over and over again you will not gain anything because that service will keep restarting it until you will give up. ah, you will loose a massive amount of battery if you do so

another thing, the google service is a system app. system apps have priority in resources so even if you kill now, as i said, it will restart after a few seconds because some apps that you are running are requesting that service.

as someone said here, yes, even I kill games after I stop playing, BUT, I do it from the task manager built in. Settings - Apps - Running apps etc.
[Android General] cybervibin:
if u dont want them to restart use, autorun manager :D

[Android General] DarkElieDravem:

[Android General] InsaneWare:
To clarify things a bit: Like already said, Android has its own task-killer. It automatically kills tasks, when theres only few RAM available. It manages the whole life-cycle of every app. The problem is, it is not optimized to a certain amout of RAM, like 256 or 512 mb, which makes it bad and laggy if you have got a phone with low RAM.

However, task-killers may sometimes seem to make those phones faster, but thats mostly not true, because it(the task killers) messes with the build-in task-killer of Android.

---------- Post added at 06:10 PM ---------- Previous post was at 05:49 PM ----------

The solution is, to tune the values and settings of the default build-in task-killer. That definitly is the best option. A few scripts like the v6-supercharger scripts try to do that, also Roms like the cyanogenmod are tweaked really good.

[Android General] Antagonist42:
Not 100% true but if you're on a higher-end device and your swap/cache/data are all on the same NAND chip you'll probably not need a task killer, unlike a lot of handsets they still have a lot of read/writes to the SDCard and that's where a lot of battery consumption comes in, killing apps that don't use a lot of RAM but are churning data constantly through cache/sdcard need killing sometimes just to stop it stalling.

But what about greenify, it ain't a task killer, just used to hibernate apps that I do not use much

Not like a traditional task killer, it's different

Correct me if I am wrong
[Android General] endolith:
Ugh. Why do people keep repeating this stuff without actually testing it? It's like a religion. "Android's task manager works perfectly already! You don't need swap memory or a task manager!" Have you even tried them?

Android's task management is only as good as the worst app you have on your phone. For instance, apps are required to save their state before they are killed, so, theoretically, they can be restarted and seamlessly continue where they left off. This is great in theory, but is disconnected from reality. If the app developer doesn't bother to write the code to save the state, killing apps starts them over again from the beginning. If the app developer only saves the minimal amount of state (like the URL of the page you're visiting, instead of the entire page), then it has to slowly reload the entire page from the web instead of quickly reloading it from memory. If an app developer includes a service that runs in the background constantly downloading ads or reporting your location or checking whether something is true every 5 seconds, it will slow down your phone. There's nothing wrong with killing poorly-written apps, and it really will make your phone more responsive. (And most apps are poorly-written, so no, you can't always uninstall them and install an alternative.)

Lollipop task managers

While it might sound good to say you don't need one for Lollipop, a quick internet search will tell you otherwise. Many users (including this one) feel their phones have been bricked by Lollipop. I was constantly fighting to maintain sufficient memory (I often fell below 100MB free) for the phone to be barely useable (not good at this point, just barely usable). A quick check showed that almost every app (closed or open) was consuming very large memory blocks (typically 50MB per app, independent of the app).

In a last ditch effort I did a factory refresh and removed almost every app. The phone now works well again. So, yes, Lollipop has a (very piss poor excuse for a) built in memory manager and many will need a 3rd party manager, will need to constantly manually close apps, to hope that M is better than lollipop or go with LG that resisted the Lollipop 5.1.1 upgrade. Another possibility is to remove most of the apps and only use the bare essentials.

I am a rocket scientist, not an amateur.

[Defy Q&A, Help & Troubleshooting] Battlestr1k3:
Hi all,

I am currently using Quarkx's CM10 Builds on my Motorola Defy red lense.

A long time ago I noticed that my battery gets empty really really fast (I would say 20 minutes of active usage in 12 hours --> 15% remaining in the evening).

So, as my charger had some problems, I decided to charge my phone after shutting it down.

Then I saw something unexpected:

As i shut my phone down it shows me about 10% remaining.

After the shutdown, with the charger connected to the device, it starts to boot in charge-only mode as usual, but it displayes about 70% remaining!

I have the impression that the battery status doesnt get reported correctly to Android in "full functional-mode".

How can I fix the issue of two different battery-statuses?

I really hope you can help me and understand my bad english,
