[Captivate Q&A, Help & Troubleshooting] RaptorOne3:
I don't mean to go digging up old threads, but I just wanted to post my opinion here on this memory clearing ordeal.

After reading the entire thread, I am even MORE inclined to want to use ATK or something similar...

At the very bottom of the post, last paragraph, it reads -

Here's my take -

While there is no way to override Dalviks operations for application retention, at least while you're operating the device you can keep the memory clear by monitoring and assisting in clearing it out, manually; Which will in fact yield a performance boost for a duration of time. Based on the description of how Dalvik operates, this is true.

Exactly how long of a duration I don't know. But it is as obvious as it gets that while Dalvik memory management is indeed cool, it is far from perfect and definitely induces low memory situations that CAN in fact cause sluggish performance. That much is already known.

So, in my opinion, if you enjoy the absolute maximum performance out of your device, ATK or something similar is definitely NOT a bad idea. Though it has to be done manually and after a period of time applications are brought back into memory, clearing the memory before opening an application allows full memory access to that application and also inevitably reduces CPU load as it removes the requirement for Dalvik to "shove" other applications on idle off the memory to make room for the active applications.

Personally, I just use Task Manager. It seems much more effective at clearing the memory.

Well, there are times when my phone is on for abt a week or so without turning off or rebooting (the times when I resist flashing roms or kernels or modems) and still I hardly feel any sluggishness. And I do NOT use any task killers. I let android handle everything its way.

And there is a difference between cleaning up memory say once every couple days, and having ATK set up to free up memory every hour or two. The first one could be helpful while the second is a battery killer.

how about file expert's memory management options?

ok - i get what's being written at the top of this. however, i do wonder about being able to tweak things some, mainly because on file expert's memory manager there's several memory config options: gamer, multi-tasker, light user, whatnot.

i got a phone to fit in my pants pocket, so it doesn't come with tons of RAM. and it freezes quite a bit when swapping between apps. of course there could be many other reasons, but still...

file expert's options don't seem to be persistent, so it's hard to get a handle on which setting would work best. now - would there be a way of making persistent memory optimization changes? if, how?

what is an amount of free memory that would need to be there for things to be smooth? by ATK, i get south of 50Mb quite often, which seems low.

i don't really like ATK's auto-kill - don't know what it will kill, and it seems that a free memory kill-threshold would be better than one based on time.
[Captivate Q&A, Help & Troubleshooting] BWolf56:
Auto-kill is quite bad as the it kills processes that always reset.

As for your ram, you could run a Bigmem kernel. 50ram is fairly normal with regular processes and a couple extras. It all depends on what you use/run.

I would need your phone's setup to help you more towards it though.

list of apps

here's the list - the forum didn't take .htm

and i'm on CM7.2.

EDIT/UPDATE: unrelated to killer apps, but for those of you who came to this thread to find remedies for RAM shortage - my observation currently is that the best thing you can do to yourself is to enable swap. that, and taking out the "play store" took me from 5 crashes a day to 1 - and after half a day of multi-tasking apps i can see up to 80Mb of swap in use, with 60Mb of RAM free, and the phone still running smoothly.

How to detect if an app is in background

In the above article it is said that the memory management is completely under control of Dalvik VM and Android runtime.

Is it not possible for a device driver to intelligently check if any app in background and release memory (allocated inside driver).

onStop(): All the rendering is stopped.

Is it possible to check some app state value to see if app in background or minimized?

Rooting a device gives you complete access to the system files and normally unwriteable areas so that you can make modifications that you wouldn't otherwise be able to do. This has very little to do with carrier unlocking, which is what you're looking to obtain.

Hey guys,

im running a Desire with the newest Leedroid Rom. Everythings working perfect,

except the wifi network connection.

My Problem:

After i updated from branded 2.1 to 2.2 with OVA Update, i cant connect to any

encrypted wifi. I dont get an error or something, it just tries to get a ip adress

and then it says Connecting... and then it starts again from trying to get an

ip-adress and so on and so on...

The only thing thats working is to connect to an open wifi hotspot.

Things i tryed:

- Other Router, other settings, other decryption, other keys,and so on

It has to be a problem in updating process, cause with 2.1 it works and after i

update to 2.2 i cant connect to any wifi anymore.

I really need help :( cause i think this cant be a hardware problem, cause everything else is working.

Sry for my english, tried my best

[Desire Q&A, Help & Troubleshooting] TheGhost1233:
First how do you do a full wipe?

Second what is a OVA update? is it the same as OTA? And what does the update have to do with your wifi not working on leedorid? Did you OTA update form a rooted 2.1 rom?

Has wifi ever worked on 2.2? What radio are you using?
[Desire Q&A, Help & Troubleshooting] nge89:
I do a full wipe with all 4 wipe options, dont know the exactly names.

Yeah sry,with OVA i mean the OTA.

No, i did a OTA Update from a branded unrooted 2.1 Desire to the branded 2.2 Froyo version. And wifi NEVER worked on any 2.2 version.

I just rooted my phone when i was on branded 2.2 version, cause i wanted to

try some of the nice roms.

In this time i never used wifi, only mobile network connection, cause i was long

time not at home and couldnt use any wifi, now im back here and trying to solve

my wifi problem.

Just checking my Radio version and i have 32.36.00.28U_4.06.00.02_2, but i dont

know why, thought i had installed a newer o.O

Should i try the 32.49.00.32U_5.11.05.27?

nge89
[Desire Q&A, Help & Troubleshooting] TheGhost1233:
Yes looks like 2.1 radio, try the newer but do not pull the battery during the update it will reboot twice and don't touch anything during the process. I take no responsibility for what happens and I suggest you do some searching on the radio flashing process. Also don't forget to check the md5 of the download.

Might sound a bit scary but if you follow the procedures and don't do anything stupid it should go well.

i encountered the same problem only i'm on 2.1 after downgrading from 2.2 and rom jumping. did a wipe and even tried to nand restore my original stock rom. is this a radio error?

2. Select my Wlan Acess Point

3. Type in my Wlan Key

4. Its says Wlan -> " The Connection is now being established"

5. Wlan -> "Authentication with "Wlan Accespoint name" "

6. Wlan -> " Not Connected"

7. Wlan -> "Scan..."

After this steps it repeats from step 4-7 again and again and nothing is happening.

Did you try to disable any protection (wep, wpa, wpa2) on your router and then connect? Also try to disable dhcp on your router and assign static IP adress to your HTC device. I had problems connecting to wifi but after I assign static IP everything is ok.

Yeah, i can connect with disabled security. With static ip and crypted wifi it

doesnt work, i cant connect.

nge89
[Desire Q&A, Help & Troubleshooting] wenck:
Then your problem most probably lies in "shaking" between HTC and router. Did you try with basic 64 bit or 128 bit wep? In many cases shaking troubles occur when one device doesn't support encryption of another. For example I had troubles connecting my windows 7 because of ****ty drivers off my wireless card. I could only use wep. Also can you check that portable wi-fi hotspot in wi-fi hotspots is disabled? And try to add your wireless manually so when you enable wi fi it should connect you automaticly without having you to enter your password.

Well most of us have some sort of background data going on. I read some posts saying that it's actually better to leave wifi ON when in a coverage area so that way 3g won't be used for background data.

Can you share your experiences on this? To me it sounds a bit far fetched and even if its true, maybe it should be considered sort of a power malfunction that wifi would take less battery than 3g??

I wanted to try it out the other day and left wifi on during office hours, but ended up talking so much on the phone that dat that the result would not have meant anything... will try again maybe next week if I don't get and clear cut input.

Thanks in advance for any info

100% True. If you are coming from another OS it might throw you. It threw me coming from windows.

It really saves battery. Try and see.
[G2 and Desire Z General] dhkr123:
Huh? Nonsense!

Maybe if you put it in airplane mode (turn off the cell radio), but simple fact is that the more stuff you power up, the less your battery lasts.
[G2 and Desire Z General] ianmcquinn:
I actually keep my WiFi on in the office and at home and believe I get better battery life (sleep policy set to never). No official tests, but I didn't use to get more than a day's worth of use before the switch. To be fair, I've made a lot of changes to my phone since then, so I don't know how much can be attributed to the WiFi change. You should definitely try it.

And I definitely don't believe it to be nonsense. The 3G radio apparently draws quite a bit of power and will constantly cycle for background syncs (which draws more power than a sustained connection for the same amount of data transferred). When the WiFi radio is enabled and connected though, the 3G radio is turned off. Depending on just how much power the 3G radio draws versus the WiFi radio and how much data you have syncing, it makes sense that using WiFi could save some battery life. The added bonus is that you use less data on your plan as well.

This might be different if you are using 2G though (since voice uses the same radio, it might be powered on the whole time anyway). No idea. Just have to try for yourself.

EDIT: Thought of another factor. Since WiFi will typically be faster, data is transferred for a shorter amount of time (perhaps drawing less power). The 3G radio also transmits data over a much longer distance than WiFi is capable of, which may cause it to draw more power as well.
[G2 and Desire Z General] tronmech:
And if your cell coverage is spotty, then the difference is even more pronounced. If you have wifi available, use it. You won't regret it.
[G2 and Desire Z General] Clivectmob:
This is indeed true, through experience i know it saves battery life, especially as someone said if your 3G coverage is patchy. The radio automatically adjusts its power o/p level depending on rx signal strength, so the o/p is more if signal is weak, therefore more batt usage. Also, it is worth noting that power is only really used when data exchange is taking place on wifi, so leaving it switched on, especially when connected does in fact save power, as when background syncing does take place, its done over a shorter period of time, again, saving overall power usage. The only time power usage goes up with wifi being left on is when out of range of an access point and the wifi is periodically checking for presence of an access point. I personally leave mine permanently switched on, and don't worry about it, it's more convenient that way.
[G2 and Desire Z General] xencor:
Cell radio uses much more power when actually receiving or transmitting data, and much much less power when it is idling.

WiFi uses much less when sending/receiving data, but more power when idling.

Basically, your mileage is going to vary based on what apps you use and what apps pull down background data. If you've got a lot of apps that constantly use background data or you are constantly browsing the web on your phone, you will probably get more battery by using WiFi.

But if you disable most of your background data services and only use your phone every now and then, you will see much better battery life by just sticking with 3G.

edit: I also want to point out that the guy above me is, in fact, wrong. WiFi uses much more power than 3G when not exchanging data, even if it is connected to a network. The battery savings you're seeing is because every time your 3G radio goes from idling to transmitting, it uses an incredible amount of battery that completely offsets the idle usage of the WiFi.
[G2 and Desire Z General] legendary1022:
I agree with everyone here, you will get better battery life with wifi because using the radio will drain battery faster when downloading. It is more efficient in pulling down data. I have mine almost on all day long in the office and at home. I do use the sleep policy, and very satisfied with the battery life on my phone.

[G2 and Desire Z General] moSess:
Sorry to say but your just plain wrong. Try it out. The evidence is there. So is the documentation from users and google themselves. Its empirical man:)
[G2 and Desire Z General] Clivectmob:
Check your information before correcting someone please, you may be right about the idle thing in terms of data transfer, although minimal, but the radio's on a phone don't switch between rx/tx like a walkie talkie does persay, but is in actual fact duplex in digital form, it involves syncronous timeslots and all sorts of complicated technical stuff. As I said before the main contributor to battery life hit on a phone is data exchange via high speed switch such as hsdpa/hsupa at weak signal conditions.
