Hey Guys,
I finally got my phone to work at a decent speed. Here are the things I did:
1. Used Apps2SD to move the apps from internal storage to SD Card. Wondering why this helped? As far as I understand the apps are run in RAM and internal storage is used for storing data and apks etc. RAM is freed up by Android as and when needed but freeing up internal storage doesn't give android more RAM.
2. Use Autorun Manager to prevent some apps from starting up and remaining in memory. Now this I understand because this gives more RAM to android and avoids unnecessary swapping when applications are started up.
3. Used 'SD Booster' to increase sd cache size to 8192Kb. This gave some initial benefits but later on it became very slow as usual.
Bottom line is I am still puzzled by Android memory and SD card management. I am pretty sure though process swapping in and out of memory is what caused my phone to slow down. My Samsung Droid Charge is supposed to have 512MB of RAM but most memory managers show only 374MB and 2 GB of internal storage and most tools show only 1.2GB. Why would this be? Am I missing something or should I use a different tool to analyze my memory.
Not sure about RAM but usually when u buy a hard drive the bigger the hard drive the lower the actual number of gigs. Maybe it is actually 1.2GB

1. This one must be a placebo effect because if anything moving apps to sd card will make the phone slower. Our internal memory has way higher i/o speeds (especially on ext4) than the measly class 2 sd.
2. This is usually not a good idea. The processes you "block" will actually still run but they will be insta-killed. They will keep trying to start up and will drain the battery.

Thats what I thought. Im no guru, but out of all the reading Ive done, they have all said that moving apps from the sdcard to internal speeds up things.
Im looking at ways to speed up my wife's droid charge. Shes been complaining about it and finally gave me the go on rooting and maybee ROMing. I would like to stick to stock if possible so she wont run into any problems but if I have to I will install a custom rom. Any links?
Nope this is no placebo effect. The phone has become very fast. There are several posts that say that moving the apps to sd card speeds up the phone. In fact of all the things this is what sped up my phone the most. Why else would app2sd be so popular? Read #4 on http://www.talkandroid.com/guides/b...lean-up-and-speed-up-your-android-smartphone/ .
To further speed up my phone I am trying to overclock. My phone is stable at 1.2GHz but at 1.3 GHz it reboots after some time. To make it stable at 1.3GHz should I increase the voltage at that frequency?

Read it again. That's only about getting extra app space on smaller-storage devices. They actually recommend against moving things you use frequently in your linked article.
I'm with the others. Any gains you're seeing from this are placebo. There's nothing inherently faster about external storage.

It has a total of 512MB RAM, and that is for everything, so the GPU and other such things have to take their share from the total pool. On the GB releases, that leaves us with 374MB. It's better than it used to be. On the Froyo releases, we only had 327MB to work with.

No, on a hard drive (or solid state drives or even SD/memory cards), what you buy is what you get. However, due to formatting, space reserved for backup/spare sectors, and what is considered a "gigabyte" to manufacturers vs consumers (1000 mb vs 1024 mb) you often end up with around 95% (probably off on that percentage) of the stated capacity. With RAM this is not the case, as that type of memory doesn't need formatting as its holding raw data with the computer making up its structure. And manufacturers of RAM are in agreement with consumers as to what a gig is.

This is the difference between a gigabyte and a gibibyte. Hard drives are usually advertised in gigabytes (literally 1 billion bytes), while most OSes use gibibytes (2^30 bytes, or 1,073,741,824 bytes), since they do everything in "base 2", or binary. So an advertised 10GB hard drive has 10 billion bytes. Once you format the drive, the OS reports size in gibibytes, so you end up with:
Code:
10,000,000,000 / 1,073,741,824 = ~9.31GiB
That's also why if you look on most hard drive packages, it says "formatted size may be different than advertised size" or something similar.
Just a random fact of the day. Feel free to ignore it.
On topic: I don't believe the giga/gibi (or in the case of phone RAM, mega/mebi) is the issue. 512MB converted to mebibytes is roughly 488MiB. I believe the Charge is a 512MB device with some of that memory reserved for OS/system-only purposes. I could be wrong on that, however, so if anyone could clarify that'd be great.
Edit: Could have sworn I read through all of the replies before replying myself. I guess I didn't because multiple people beat me on both points by a day. Sorry about that duplicate info.

The number one lesson I learned from buying this phone
Check the amount of run time memory before you buy a phone, especially if you have two companies like Verizon and Samsung loading bloatware. You were forced to root the phone and rid yourself of the bloatware, or not buy apps. I totally agree with the OP. He is 100% correct about the run time memory.
So I restored back to factory to get ready for another root. After the required Verizon and Samsung updates, hitting the clear memory button, I'm using 268MB of 373MB. Now I know the OS can swap, (because we love paging), but it really is ridiculous. I can't wait until March. Good luck everyone.

I couldn't understand what you are saying here. From what I understand you are saying that is that when you rooted your phone you had 512MB of memory but after you installed Verizon and Samsung updates it started saying you had 373MB. So is it that Samsung and Verizon updates are taking away about 147 MB of memory? What is going to happen in March?

No. Hardware wise the Charge has a total of 512 mb of RAM. The GPU and other hardware have to take from that pool, and the end result is that the Android OS has 373 MB of RAM to use. Verizon and Samsung bloatware and updates have no control over the hardware aspect, but the bloatware DOES utilize some ram while the phone is running (but does not take from that pool). March is probably when his upgrade is.

I am using Eclipse 1.4 with PBJ.
Ok so I can clearly see that my phone is becoming slow again. Not sure as to what it is related to. Though one thing that surprises me is that I overclocked the CPU to 1.2 GHz and set the governor as 'conservative' and sometimes even ' smartassv2' but it changes to 'ondemand' even though I never changed it to that value. Why is this happening?

Plugging the phone into a pc does that for some reason.
Sent from my handheld computer using electromagnetic radiation.
I have to agree that even though my phone was initially fast it slowed down considerably after some time. Frustrated I then backuped my phone using Titanium backup and installed Tweaked 2.2 Rom + PBJ. But this time I did the conversion to EXT4 and the phone has become super snappy and the fastest I have ever seen. However, I am not rejoicing right now because I have only installed some very necessary apps like navigation, yelp etc. Don't know if the phone will be come slow after I install more apps. On Seepu I can see for the first time my used memory is green and this probably is a major reason why the phone has speeded up. Another factor is the EXT4 conversion.
Infinity was known for slowing down over a short period of time. Tweaked 2.2 is quite a bit better. But running a Droid Charge for several days without rebooting it once in a while will cause it to slow down too. Just reboot when it starts slowing down. It should help.
Before I add any more apps I want to save this state of the phone so that I can go back to this if the performance degrades. What do I have to do for this? I used Titanium backup but I see that it saves app data and you have to install each individual app. What I want is to make one click and restore my phone back to the state it previously was. Should I do a nandroid backup

We all know that PCs use pagefile, that helps when running on small amount of RAM. Our UNIs have 64mb, that's not enough, it alows us to launch 1-2 programs simultanously and that's all. running out of RAM!
I wonder, is it possible to assign part of our SD card's memory (approx 64mb) as RAM (pagefile or memory dump, doesn't matter). It will be rather slow than infeneon chips but it's worth trying&using
Dear ROM developers, think about it. Maybe it's possible...

Even if one was able to get a working method, it would be highly risky and incredibly slow. The Bus speed is so low on the Uni, and having "Data" paged to your SD Card would be a very dangerous solution to running a few more apps at once. Performance wise, it would be like paging to a USB 1 flash drive on your pc....
I would rather know my open data is safe than take the chance of it being corrupted or lost on SD card.
Just my views....... wait for the 128 mb upgrades........
And, instead of having 45Mb storage and 50Mb of RAM, is it possible to make 20Mb storage and 75mb of RAM???
or used the storage intern for the pagefile???
I'm in the process of deciding whether I get the Inspire or wait for the Infuse. I'm new to smart phones, but been reading a ton.
My question; is the 4 GB on the Inspire sufficient for the numerous apps I am likely to put on it? I think I've read about apps that let you place apps on the mSD. Is this even a concern I need to worry about?
Thanks for the help. Searched the forum and didn't see this addressed. Probably means it's a dumb question. I'm trying to get smart
Unless your going to have a couple hundred apps you shouldnt really worry to much.

I've downloaded plenty of apps and never even gotten close to using up the internal memory. I move what I can to the SD card, usually (it's not hard to do, and it's a feature built into the phone now).
Ditto, you'd have to work pretty hard to fill up that space, most programs are pretty small. But remember that many applications now support the A2SD function, so in the unlikely event that you start running out of room, moving them to your SD card is an option. I notice very little performance difference between apps on the card and apps run internally.
im really upset about the lack of ram on this device, i have a ffew apps and i only have 100 mb of ram left, and i have task killer, memory manger, but folks.... i dont think we all are realizing that this phone is handicapped because......ram i sso damb important... this smartphone would be up their with thor, if they just gave it the power or ram for which it deserves... damb, do i exchange for sensation...... hmm,
how important is ram everyone...... do we need 1 gb in order to be future proof or are there ways of getting around the 512 thats in the phone, for our future needs
You complain too much about this device on the forum. Get a different phone then and stop *****in'. Your not contributing anything to this forum with all the negativity
U don't need tons of ram unless your trying to download all the apps in the android market. Even tho apps dont really store to ur ram per se
Sent from my LG-P999 using Tapatalk
When you download apps in the market, they are not stored in RAM. They are stored in your /data partition which is like 1.6GB.
RAM only holds what is running at that time. Keep in mind, if nothing else needs RAM, android system will NOT reclaim it. Empty RAM is wasted RAM.
I have noticed one problem that I think might be related to limited RAM. Several times I have seen the phone come to a virtual halt (in fact, the first couple of times I thought it had altogether frozen, but it was just running maybe 100x more slowly than normal -- the spinning busy circle would advance one tick every 30-60 seconds, for example).
Every time this happened it was when I was using Firefox and had opened 8+ tabs. Eventually after a few minutes if I let it run instead of pulling the battery, things would clear up and the phone went back to normal performance. I limit myself to about six tabs now and I haven't had the problem again.

This may be because of Dalvik VM Heap Size? I'm not 100% sure, but I believe it dictates the maximum allowable RAM usage for any single app. Default value is 40MB. Maybe 8 tabs is the point where Firefox is using that whole 40MB? You can change this value, and I believe it's in the build.prop? Run a backup, bump the value up to say... 64MB and see what happens?
I've used up to about 6 tabs in the stock browser and haven't had any issues like the one you describe. Frankly, I don't think it's caused by the phone having 512MB RAM.
512MB Doesn't handicap this device...it's the new standard and APPs will be built with that in mind. Having more RAM would just allow Android to hold more inactive applications in memory and so speed up the launch of those APPs by a negligible amount. You'll be well on to your next device before you need more RAM.
s 3G/4G signal and ram
1. *#*#3282#*#* enter msl to change port #'s to 0 and 0.0.0.0 so 3G is faster. Are there different instructions for ns4g. Port #'s under multimedia and says they are not set. So I'm asking if the hack for getting better 3G works on this phone ?
2. Since storage is built in, can it be allocated as virtual ram. I have seen this question before, but it always refers to a removable storage card. Don't really want to free up ram, just have more for usage.
I have searched, but maybe the question isn'tbeing asked correctly. If there is a point I'm missing, i would appreciate any info.
Was told first question doesn't work cause we don't use proxy port for 3G/4G on ns4g, would like to know what is uses and if there's a hack to get better signal

Didn't see Q&A for Android Development
Can you elaborate on why you can't use storage memory and allocate as virtual ram. Just like on a PC, i would think because its apart of the phone and not removable.
Because ram in a PC is volatile, meaning its meant to be written to and rewritten to continousoy as long as there is volatage applied. The cathc is when that voltage goes away so does the information.
With SD storage like we are often dealing with on our phones it is nonvolatile memory meaning it can keep its data after the voltage is removed. The downside to this is that it is designed to be written to and stored as opposed to constantly being written to like RAM is. As a result, this type of memory only has a certain number of writes that it can have performned on a certain area before it goes bad and cannot be written to anymore. In essence it "goes bad".

So i take it that when a PC uses the hardrive as virtual ram for a bigger cache, then its essentially doing the same. Explains alot more than what Eastwood was sayin.
Heard about removable SD cards going bad from wear, was hoping because this was permanent storage almost like a hardrive that it could simulate the the same way. Prolly means my harddrive is gonna go pretty soon on my PC then.
Was also asking because most of research i read was related to removable SD storage, and since my storage is built in and not removable through a slot like most phones, i was curious if the method would be the same. Guess not

So the prl hack only works for some people, witch is not me. And trying to allocate memory as virtual ram for a larger cache is not going anywhere. From what i have read this is theoretically possible, but has only been done on removable SD cards. Witch wears the card down and is too slow for usability. This phone is way better than my old Evo 4G, but didn't have battery issues or signal issues on Evo 4G. Guess its back to Sprint, cause I'm still within my 30 days.

It was like that even before I rooted. I noticed it but it didnt really phase me until recently. All my music/pics are on my card. I had to jump on HTCs site just to confirm that I was supposed to have 8gb and wasnt remembering it wrong..lol. But any insite to this would be helpful. Again thanks in advance for any help
I do believe it has 8gb but 3.2 gb of it is partitioned...
Sent from my ADR6400L using XDA App
I believe HTC partitioned it in a way that only 4GB of the 8GB eMMC is usable (the other 4GB is out of reach, it seems), and within that 4GB, you only get about 2.5GB or so user space, with the others reserved for the system.
And since it's one time only, we cannot reverse the effects of that partition.
Ya it is pretty ubsurd that you lose about 70% of your internal memory.
I do think it was smart to partition space for the system in excess of what is required, just to keep it stable.
Also, I imagine HTC had to put aside a hefty chunk of memory for HTC SENCE.
However, that seemed like way too much when I first encountered the problem myself.
So I e-mailed HTC who told me that the thunderbolt only has a 4GB eMMC under it's hood. That would make the numbers make sense because then the formatted space would be about 3.8 Gbs and that would mean only 1 gb was taken for the system.
why doesn't HTC or Verizon address the misprint claiming it has 8GB eMMC ?
that is a quesiton I can't answer.

This same question came up when the G2 came out and everyone was rasing holy hell about it.
Physically there is 8gb in the phone. However, if I remember correctly (you may need to Google it), the explaination was that because of the way Android uses memory, it is unable to use the extra memory properly. The only analogy that makes sense to me was like how in Windows, unless you set up your hard drive as NTFS, instead of FAT, you were unable to format a partition over 10mb.
Samsung got around it by showing the "extra" memory as another "partition" of sorts so the memory shows available.
So to make a long story short, the memory is there, but system limitations, along with some of the memory being used as backup cause you to only see the 4gbs.
At least that is the way I understand it. Maybe someone else may know more about it and can explain it better.
It has an 8G flash:

# fdisk -l /dev/block/mmcblk0
fdisk -l /dev/block/mmcblk0
Warning: deleting partitions after 60
Disk /dev/block/mmcblk0: 4487 MB, 4487905280 bytes
There's over 4G available as a flash device to the OS. I suspect the rest is where the radio code is stored, and is not visible to the Linux side.
