Hi all,
A few of us on the SD card list thread have tried this and it seems to be stablizing things....the theory as we are working with now is that the problem is due to a power control issue in the Samsung drivers for the phone, not especially in the card itself.
No ill effects have been reported as of yet, and the battery life seems to be on par with before the switch was made. It is a simple fix, and can be reversed easily.
I ran the phone for 2 months without a card, and with these keys toggled, it is actually FASTER than it was. I don't fully believe it, but it has been over a week and rock solid.
First off, you need to dev unlock your phone. See the thread here for simple and complete instructions: http://forum.xda-developers.com/showthread.php?t=938106
Next off, you need to toggle the following 3 registry keys in the Registry Editor provided in the above post:
The keys have to do with MMC (internal memory) power management.The big speed improvements is in games/apps (Fruit Ninja opens and operates leaps and bounds faster than it did when the phone did stock!)
Code:
HKEY_LOCAL_MACHINE>Drivers>SDCARD>ClientDrivers>Class>MMC_Class>DisablePowerManagement (Change to 0)
Code:
HKEY_LOCAL_MACHINE>Drivers>SDCARD>ClientDrivers>Class>MMC_Class>High_Capacity>DisablePowerManagement (Change to 0)
Code:
HKEY_LOCAL_MACHINE>Drivers>SDCARD>ClientDrivers>Class>SDMemory_Class>DisablePowerManagement (Change to 0)
One point of note here, do not be afraid if the phone locks up the first time soft resetting after these changes, mine did and it was fine after a battery pull.
Also, I would be interested to hear any theories about why this one made such a big difference when it seemingly affects only the internal storage. Maybe because the two storage devices are "bridged" by WP7?
Comment below with your experiences please!
If this gets enough test results, we will submit it to Microsoft. Thanks!
As I already mentioned:
Up to now I just did the SD card registry hack. The device is now stable for over 3 days, longer than ever before.
Battery life wasn't noticable affected, lasted for around 40h with moderate usage (thumbs up indeed).
In fact without this registry hack I wasn't able to get down to an empty battery without those reboting/dataloss issues.
But I need some more days, then I will change the MMC registry key also.
No speed improvements mentioned up to now.
I applied the hack to all three keys. So far, it is much less laggy. Not sure if that will return after 4+ weeks as before, but here's a pretty cool side effect:
After the hack, my screen does not stop responding to touch when the phone is placed on my desk or a soft surface, like a couch cushon. It was getting really annoying because I often place mu phone on my desk during the day for easy access, but every time I tried to onlock it, it would not respond unless I picked it up. Sometimes, it's nice to leave it lying down and operate it. Couldn't do that before, but I can now! WooHoo! Thank you for this.
I'll report back if it starts up again in a couple weeks.

Whoa! I just tested this and you are correct! More proof that the Samsung power drivers are full of problems. Who would have thought?
For testing purpose I changed the MMC Keys also and made some Videos (no I won't upload them). There were absoluteley no differences in app loading times (ok, i know the longer loading apps are pretty much all stored on the sd card, ) and also not in overall performance, although this isn't provable easily.
I changed the keys back to normal, but kept the sd card key change to 0.
I address the positive speed effects to sdcard key for now. Perhaps i will make some tests without any reg change in the next few days.
Still stable as hell!
Edit: Damn I forgot to test the not responding problem (even though i didn't notice it that often and badly)

As I mentioned above, I'm hoping it's not just a result of resetting something and it still returns in a few weeks. Although, the thing about the screen touch response not working when laying on something is COMPLETELY GONE! That alone is worth the setting change. It really was annoying for me the way I use the phone. Thank you to eveyone involved in finding this setting.
PS: From my perception, I don't believe my battery is behaving any differently. Although, I would imagine if it were scientifically tested, it surely would be using slightly more juice. But it still had the normal amount left in the evening, and I probably used it slightly more testing it out. Maybe getting the screen to perform better uses less power?
For the sake of completeness: I set the sd card key back to 1, and I do not experience any slow down in overall performance or in app loading times. Still I cannot reproduce any of those not responding issues you mentioned.
For today and tomorrow I will stay with this setting an will wait for a random reboot. Let's see what and when it happens.
tried this with a 16gb class2 sandisk... loaded it up to 9.25 left and the reboot monster came... but it was weird... it would rebllt like every 30 sec with no loss then poof all lost...then rendom self reboot all mem would reappear and start the reboot process all over.... now it didnt do this till it was unplugged.... plugged in it was fine... reformatted... re set up did the tweak... loaded and the same as before... so for me no... but im going to test it with another card on the list... heres to hoping....
but it does fix the sitting on the bed and unresponsive gimmick.....
So would this be worthwhile even for someone without an sdcard? For the screen response issue i mean. It's so annoying haha.
edit: Screw it i went ahead and did it hah. It def fixed the touch screen responsiveness issue!
Which cards?
Can you guys post the specific SD cards you are testing this with. I am curious to see if somebody has tested it with the Sandisk class 2 32gb card. Thanks.

Sebo's testing with a SanDisk Class 4 32GB card which ended up being more stable (before it failed and before he tried the registry stuff) than the Class 2s from Sandisk.
Based on what you have read, would it be best to get rid of the class 2 32gb card or wait to see if there is an actual fix? Since this seems to be a power issue based on the fix, does it really matter what class it is then? Thanks.

Something to keep in mind is that this registry hack is relatively new. Some people managed to go for weeks without issues on an unmodified WP7 with a card. It's entirely possible that these hacks are just a stopgap, or a reset, and actually *fix* nothing.
Theoretically, the card shouldn't matter. If I hadn't locked my 32GB Class 4 Kingston to my old (bricked) Focus, I would try it with the current one and see if doing the registry tweaks fixes the slow sync issue on it. Someone in the SD Card List thread claims to have done the registry tweaks and it ended up failing badly too with a 16GB Class 2 Sandisk. However, the 16GB Class 2 Sandisk is one of the more reliable ones (without tweaks) through the limited testing this board has done, so it's possible he has a bad card.
In brief, it shouldn't matter (within reason) what brand/class/capacity you use. If this tweak is the real deal, it should work, especially if your only concern is random reboots. However, you still would want to avoid cards with extremely high class ratings at typically their random read/write is slow (which the most common usage of the storage in WP7). In terms of performance, there's no guarantee as to what these tweaks will do as the only consistent change has been that phones that would constantly reboot due to their cards aren't (yet).
However, to answer your initial question, I don't believe anyone has tested a Class 2 Sandisk 32GB card. I wouldn't put too much faith that your card will have the exact same results as Sebo's class 4 because we aren't certain what the cause is. We believe it's power, but we're not 100% sure. If you're already using the card in your phone, you don't really have much to lose. If you're not using it yet, then you only have something to lose if you, like me, don't have a Nokia/Symbian phone that you can use to reformat the card if it fails.
Good post fishface.... That's where most are thinking its a fix.. This is just a theory right now.. That's why there's another post wanting testers... my find was it did fix the sensitivity issue...theres no doubt on my end.. But card wise my 16gb class2 SanDisk worked before I tried this until I hit 15gb used... Then it went goofy... I tried it 5 times.. Same thing. Just about 15gb used was where the instability happened. Soon as the reg hack hit I read thru it.. I love reg edits.. Made my Omnia 2 &hd2 quite decent phones... That's when I saw the mention of others thinking this too.. So I took my 16gb class2 SanDisk that I freshly brought back to life, and decided to test it out... I posted the results before... Plugged in no issue.. Unplugged it went goofy at 12.7 used... I was stable at that point before without the edits... Not saying it doesn't help but it made mine worse... I'm still going to try other cards though .. I do think there is something to this... I might try different scenarios of the edit... What's it going to hurt..i mean were here for the same goal to help find a solution... Well except the lurkers..you all know who you are..lol. But again. Great post fishface...
Thanks for all of the info. I guess fix is the wrong word to use, but i was just trying to get an idea of what others have done. Whenever i would pass the 10gb mark, mine would do a full wipe after a couple of restarts. I still have my 32gb card in my phone, because there really is no point of taking it out and possibly loosing it. Plus i was hoping an official fix would come out so i could just apply the patch. I have been waiting to see when the MS update would come out so i could do a full backup before running test. Thank you for your help.
anyone tried messing with block sizes? Default is 128. I'm wondering if maybe your sd card has trouble with that block size its causing the lagginess. Who knows lol....

Also I'm still using my 32gb Kingston class 4. I have all 3 keys set to 0. And its still going strong other than that one reset I had. MMC block size 128 sd block size 128. If my sd card can't handle that large of a block size I would have instability.

Anyone know if this also fixes the song stuttering issue? That's definitely power related since it only happens in the last couple of seconds of a song if the screen is off. One you turn it back on, the music plays perfectly.

I'm stuck. Made it through the first three downloads and have my phone unlocked.
Followed Registry Editor link and downloaded RegistryEditor 1.1.0.0.xap. My computer will not open up this file because it doesn't know what program to use, so I tried to download it straight to my phone and my phone says it doesn't support xap. What steps am I missing?
How do I get into the registry to change the three tabs?

I've been using the hero for about a week now, pretty solidly. At first I was getting annoyed with laggy accelerometer, laggy screen switches, lagg keyboard... last few days it seems like it has sped up hugely. I normally have a few RSS feeds, hi msn, music player, browser, maybe last fm and a few other bits open, especailly yesterday and today have noticed no appreciable slowdown.
So for people who are getting annoyed at sense, give it a week. I think dealing with a slightly laggy phone for a few days is a decent enough tradeoff for eventually getting a fast one, that still has the joys of sense.
Does anyone have any idea why it gets faster? Could it be a mechanism similair to windows superfetch, or perhaps some kind of self-optimising code? Or just psychological Whatever is it, I no longer get those little flashes of annoyance with the thing.

It will be this.
Cheers, I feel enlightened.
I personally suspect there's some kind of profiling/prefetching going on in android, maybe based around the preload daemon.
Did you change to a class 6 microSD card? I have heard that android maintains a swap file on it and everything works better with a class 6 card rather than the slower class 4 one supplied in the box.
Just a thought...
I've been using a Class 6 card since i started using the hero and i haven't noticed any lag at all. For those who are experiencing lag, is you handset unbranded?
Hm. My UI actually slowed down instead of speeding up. This especially after I rooted the Hero and installed Chinese IME. Might also come from the fact that the number of apps on my phone keeps growing and growing...
I'm white unbranded (beautiful...) and there's quite literally no lag anymore. You know the bit where you type and get ahead of the keyboard? Stopped happening on tuesday.
Man and machine in perfect harmony
I've also experienced some terrible lag on the keyboard and am hoping that what you report is correct. I should also be getting my 8 gb micro sdhc card today or tomorrow (class 6) so hopefully that will speed things up a little also. I'll let you guys know how It goes.

Depends, some cards there is a number in the top right corner, others just don't have anything. There is a program for the PC when you put the memory card in a card ready which will assess its speed, just can't remember what its called.
Mine is lagging as much as it was on the first day. I'm curious about the class6 sd. Maybe it's a solution. Thank you for keeping in touch about that
My keyboard has slowed back down again It's started lagging and selecting the alt-key at least once a text message. The rest of it seems to have slowed back down aswell. I'm going to try work out what's doing this, at the moment the two new apps I've used are Peep and imeem.
I believe I have an 8gig class6 sd. Might be class4.
Using a class 2, 4 or 6 won't speed up the UI since it's on the main memory not on the card.
I have a class6 and it is laggy
Whilst most of my experience with the Hero has been lagged it just seems to get worse day after day.
The keyboard for example which I loved at first has become quite appalling to use now, I mean i've never been a fast typer on virtual keyboards but I feel now that with the keyboard as it is now on my phone is actually slowing me down further!
The phone slows down a little for me to from time to time. I just reboot it and it is real fast again. Also I'm hoping that the Class 6 Transcend card will give a noticeable boost.
Klling peep really seems to help. It does seem like a good amount of the HTC software has lots of room for improvement, but it makes the phone so much nicer to use than standard android. Hopefully we'll get an update soon.
why don't the apps just close when you shut them? ok i understand peep and mail... still running as it updates at intervals but i had 10 apps running last night, albums, video player, barcode scanner, google maps, doggcatcher and more, the phone was almost unuseable.
i know mine has speeded back up after i uninstaled a few apps.
Locale seemed to really slow mine down, Peep does as well, and astrid kept causing the home button bug.
Since i got rid of those, it is a whole heap better.
mm i use astrid, what is the home screen bug? do use any other app in its place?
hadn't even started using it to be honest. got it as a plug in for locale so i could have GPS based reminders, but didn't get a chance to try it out.
basically the bug is in a few other threads, where once you hold the home key to view recent apps, it unlocks the binding to touchflo and it asks whether you want to use touchflo or the base android homescreen.
stopped as soon as i uninstalled astrid. also happens with Task Manager by Wing Shen. but that is another thread....
Is anyone else getting random lockups on their phone? it seems like no matter what rom i use it locks up at least once or twice a day. it seems that sense is the only thing that does lock up, as i cant hit the home button and have it go back to it.
anyone?
yeah, it happens to me too...to the point I have to remove the battery
Same here, it usually locks up once every 24 hours or so, and most times it's not even a full lockup, just the homescreen does. cause i can hit the windows button, and end button will lock the phone, just the main Today screen. Sometimes time fixes it, and it'll fix itself. but most times i take battery out
It all has to do with sense.....Horrible i know

I have had the same problem sense I purchased on Mar 24th, after trying to restore the devise 4 times within a 2 week period, I finally took it back and exchanged it for a new one, less than 24 hours, the new one froze up on me too. I searched through many forums such as this, and found that many users are having the same problem, I also read in one that the cause may be in the SD card that comes with the devise (the way it's formatted for use with it), so, 4 days ago, I removed the SD card, and the devise has worked flawless, no freeze ups, and for the last 2 days, I have not turned the devise off, and still no freeze ups. I plan on giving it a week, and if it does not freeze up on me, I'll put the card back in. I reformatted the SD card to get rid of the Double twist program, and the other apps such as the demo games, and put my music, Documents, and Photos back on it, hoping that it will work as a normal SD card when I put it back in.
Give it a try as I did, it just may be that simple fix everyone has been looking for.
Also, just for info, I'm running the stock USTMO ROM, with Cookies Home tab version 1.7 on it, Awesome and Flawless, if you don't want to flash a new ROM, you have got to at least install this add on.
I'll keep you posted on whether or not my test is successful or not
Same here
I've hard reset this thing, seriously, 20 times. Same setup as yours. I will try the sd card removal. Thanks for sharing the info.

Thanks for that bit of information. I went ahead and formatted my my sd card today. (Fat32, 32kb allocation unit size.) the phone hasn't locked up yet. i feel that by this amount of time i would have seen one. i'll post another reply if it locks any time soon. thanks guys!

Well, It's been 6 days and no freeze ups with the SD card removed, tomorrow I'll put the reformatted SD card back in and test it further, so far, so good
Here's a question: Do you think T-Mobile put the fastest SD cards on the market in this phone?
I simply changed the provided card for one that I purchased a week or so before I got the phone on launch day. No problems.
The ones Tmobile put in there are cheap class 2 cards. Reformatting the card has seemed to help. You would probably have better luck with a class 6 card. I'm going to wait till the price of the 32gig cards come down then get one.
EDIT: OK so I reformatted my card and its only showing 14gigs of storage, I know its not going to be exactly 16gigs of storage but I should have more than that. Anyone else have this issue?

droids come with a 8gb.
Still without issue, no lockups.
I also noticed that it was only 14.x gb free. i think its normal though.

defective phone
i think the ramdom lock-ups are associated with the phone and not the custom ROMs. i've flashed about 6 different TMO-US rom from here and they all lock up my phone. so they all can't be bad, right? well, the other thing i noticed was that when it did lock up, i could feel the bottom-half of the phone was hot, right below the battery cover. i think my phone is defective because if i multi-task, it gets hot then locks up. i'm going to return it for a new one. anyone else have this problem?

Well folks, I put the reformatted SD card back in, while I was scrolling through my pictures testing out the card, guess what, the devise froze up, had to reset it, about 4 hours later, while going through the pictures again, it froze up again, reset it. Then, as before, after a long charge, the phone would not wake up, had to reset again, that's 3 times sense I put the SD card back in. To test the card out thoroughly, I watched Transformer part 1 to the end, and no freeze up, so I cannot say if the SD card is bad, I'm getting ready to try a new card now.
The problem may be with the Devise's SD driver. Another thing I noticed is that with the card out, the battery lasted a good 50% longer
This is just my test, but, it seems to me the devise runs better without the SD card installed.
I'll return with an update after the new SD card test run
****Update: Tried the new SD card, the devise froze up while scrolling through the pictures. I don't believe it's the SD cards, seems like a glitch in the SD hardware or the SD driver. My devise works just fine without the SD card installed, who would think that it may be the SD drivers causing the freeze ups. I wonder how long it will take for HTC or WinMo to accept and fix the problem.
Is there a developer on this thread that can come up with a fix, or a better SD driver software?

Same here, the back of my phone would be hot as well, try removing the SD card for a few days, as I did, and see if your phone stops freezing up, mine seems to work great without the card installed, and the battery last longer.
will buy a new one and see
i def think its the card, maybe it gets hot when you charge/ run heavy apps like wifi and when it goes to read the card it miss reads and freezes, cause i install all apps on my card as to not clutter the fone just yet, i will def be buying a new sdcard and probably swapping out cards hahaha and returning old stock one. hahah thus having a sweet better class 16g card for free
I get frequent lockups with Sense, but when I switch to the standard Winmo interface, it never locks up. I don't think it's the memory card as much as HTC's sense.
lock up exiting messaging
I have had the phone since the 14th, I am running the stock T-Mobile USA rom (not flashing another rom until I decide if I'm going to keep the phone) The only time that I have had the phone lock up is when exiting the messaging tab on Sense.
It seems to have started after I updated the myphone application in order to back up text messages.
I've always read the thread about battery life problems on here thinking "Thank **** mine doesn't have that problem" - luckily since I bought mine in December the battery has been quite impressive really.
But a few days ago it suddenly started losing power VERY fast. I'm talking about 10%/hour even on standby, so I undid changes I'd made recently and it made no difference.
Then I read through loads of other threads on here from people who had poor battery life on their phones to look for clues/solutions.
It seems that the responses are (understandably) fairly consistent, eg:
check for stuff running in task manager
remove changes recently made to the phone/uninstall recently added apps
make sure your data/wireless etc isn't doing stuff it shouldn't be
turn off automatic updates
turn down the screen brightness
check activesync
do a hard reset
upgrade your radio rom
etc
All of these of course make sense and are useful suggestions, but it seems there are a good few cases where doing these things don't help, ie you check out the different potential causes and none appear to be responsible. And in the case of sudden poor battery performance you can't point the finger at the rom/screen brighness/auto updates if they are only doing the same as they have been for ages without issue.
So is there a genuine case for the batteries just suddenly 'going weak'?
I've resorted to a hard reset on mine last night after assuming something had got corrupted hence why I could not find the cause of the sudden battery weakness.
But it hasn't helped - it's still dropping approx 10% each hour while on standby, even on a basic install, without even all the apps I normally have.
To me therefore it logically has to mean a failing battery if a hard reset does not help - or can anyone argue why that might not be true? The only exception I can think of realistically is a hardware fault with the phone.
Have ordered a new standard one anyway, and a hicap 'bulge' battery, so I'll post up if the new one cures it. Quite a few battery threads seem to have no conclusion, so ultimately they're not all that helpful in those cases.
How many other people have had issues like this where the battery life has rapidly gone downhill and a new battery has solved the issue?
Also, has anyone done any tests on their 'dodgy' batteries to see if they are indeed going bad or if it's the phone at fault? For instance (really basic I know) if I were to hook up a light bulb to the battery and measure how long it lasts before it goes dim, then compare it to the results from a new battery, would that be worth trying?
If that's the case it's p1ss poor that a state of the art phone can't even go 6-7months before the battery is junk!
I understand and appreciate that li-ion cells only have a certain number of charge cycles (like most rechargeables) but this takes the cake!
My old XDA orbit is years old, still has its original battery, and that has not deteriorated by any noticeable amount, so these shouldn't either.
See: http://forum.xda-developers.com/showthread.php?t=688496
and let me know if the new battery fixes the problem. I think the batteries might be crap and prone to failing early.
Thanks for the link - sounds exactly the same as my issue.
Hopefully the new battery packs will sort it but that's shocking quality control or product design/testing if these are failing so quickly.

Yeah right. But that has not solved the problems with the 6 month old phone.
What i have not read in the post of Cret is that you took the memory card out and see if that improves battery life. a corrupt file on the memory card causes a huge drain.
try because that also happenns suddenly e.g. after been connected to a computer and not disconnecting properly.
That's a damn good point actually - thanks. I had seen that mentioned in other battery threads yet somehow completely forgot to try it.
I will try and see whether it makes any difference - cheers.
If that should turn out to be the cause of the problem how do you resolve it?
To elaborate - I don't imagine you can easily identify which file would be the culprit, without formatting the card and adding the files back one by one and testing for the fault to re-appear. That's totally impractical, almost impossible with the number of files you can fit on a 16gb card, and the time it would take to carry out that process, so what do you do?
Or is it possible that simply copying them off the card, formatting it, and pasting them back would somehow resolve the issue.

Doesn't this usually result in filesys.exe spiking up to 100% (or just high) CPU usage, though? It isn't doing this on mine, although I'll give it a shot without the SD card. I would expect better battery life without an SD card in anyway, but nothing dramatic.
Cret, let me know if your new battery sorts the problem so I know to buy one myself!

What are you talking about? Again, you enlighten a thread with useless information. You can clearly see the OP has had the phone for 6 months (as have I) and the battery is failing (as is mine).
Plus, your battery must defy the laws of physics if it gets better day after day. Interesting.

What you can try is put the memory card in a card reader and run checkdisk on the card. see if that identify's any problems on the file system
beside of that it seems that the HD2 has problems with 16GB cards, at least quite a few of them. read through the posts.
Id suggest to collect more data about the problem.
The program BattClock lets you check the battery drain in mA. A normal drain for the HD2, with no processes keeping the CPU awake, is 4mA in standby, with only the radio being powered to receive calls.
So, since the battery current value isn't update instantly, right after you wake up form stanby battclock should be showing 4mA (max6-7mA or something lik that) fora few seconds. If that's not the case, and if the drain is way higher than that, then it may be the case that the phone for some strange reasons is draining more current than it should, and it's not a real battery fault.
I had a similar issue, solved it by disabling auto backlight. Set it at 30% and all good since then.
Well, I thought there had been a slight improvement over the weekend with this battery issue but this morning on standby the phone dropped 3% in a matter of 5 or 10 minutes on standby.
So I removed the mcirosd card and in nearly 3 hours since then it has dropped another 4%. That's a big improvement and does hint that the card is the fault, but it's too early to be sure about that. I've put the card back in to see if it begins to drop fast again. If so I'll take it out for longer and monitor it again.

Good idea. I wasn't aware that the phones had problems with cards this size. What about with 32gb ones (not that I can afford one!)?

I did use battlog briefly, but just to keep an eye on the current current amount in use and it was fluctuating a lot just with the phone awake but running no apps. Sometimes it after waking it the phone would show a low figure like you quote but other times not.
I haven't checked batlog out fully in terms of what it's capable of, but what would be great would be an app that can log the current use like that does, but at the same time also log a list of which processes/services/applications are running, then that could REALLY give some useful info.
Eg the log shows normal current use, then spikes upwards when a specific process begins to run.

make a request for this feature in battclock's thread
The author seems to be quite open to useful suggestions (I, among others, suggested the log-to-txt feature )
Would be a good idea - I like BattClock I must admit. Nice to have the taskbar info like it does.
Ok, later on in the day, it's worked out that it's used 35% battery in approx 3.5 hours of standby - pretty horrendous. Equates to about 10.5 hours (very roughly) battery life on standby. I've checked periodically during this 3.5 hour period and the drop has been steady.
With the card removed, it went 3 hours and only lost 4%, meaning approx 77 hours of standby time at that rate.
Quite a difference between the two.
So at this point it very much looks like there is a fault relating to the memory card.
I'll try some testing tonight. Mainly that will mean I'll first do a filesystem test as suggested. Then delete all the media files, cut the remainder of files and paste them elsewhere, format the card then paste them back, and see how it then behaves.
So it seems now that buying new batteries (and almost slagging off the HTC one) was slightly hasty, but they'll still be really useful, so I'm not at all bothered about that.
Try putting the blank card in, with nothing on it. Would be interesting to see how much juice it draws just having a card in there without reading anything from it.
I have the same issue.
My HD2 worked like a charm, only around 12% battery drain in 24 hours (I could carry it around on standby for one week before recharging).
Now - it sucks around 3% per hour. After one day, I'm at around 25% charge
At first I thougth this was related to Co0kie's Home Tab, but even after hard-reseting, it still drained battery as hell.
At the moment I'm running it without memory card (4GB Kingston) to see if this might be the issue...
I've run a CHKDSK on my memory card just in case, but the filesystem's fine. Any update, Cret?
Well, I'm sure mine was caused by the card, or at least a fault that related to it (ie possibly a file rather than the card itself).
Since I removed the card the battery life returned to normal, so I formatted it, and then copied some of the content back onto it again. It has been back in the phone for a little while now and has been behaving quite well. Basically for instance it's at 77% now at 10.30pm after being removed from the charger around 8am. I haven't used the phone much except to check emails a few times, read a few texts, and go online a couple of times/read RSS feeds a little.
So I'm fairly happy with that.
BUT - not having had the chance to use the phone much (ie mess about) since I formatted the card, I just found that the phone thinks there is no card inside it at the moment for some reason!
I removed it and the PC can read the card and its contents no problem but the phone cannot see it. The only reason I can think of for this is that I formatted the card as NTFS instead of Fat since it's meant to give faster performance, but is it possible that the phone itself does not support this format?
Since it's not working at the moment I'll have to try wiping it and changing it back to fat again.
Yes I have tried rebooting it also.
Next thing is th double size replacement battery I bought arrived the other day. The battery fits ok but the replacement cover that came with it does not fit properly at all.
The cover clips in ok on the side of the volume buttons, but no matter what I do it just hangs loose on the opposite side so I can't actually use the bloody thing since the battery will just fall out like this. Really not happy at all about this.
This is the one I bought:
http://cgi.ebay.co.uk/Extended-2400...eBatteries&hash=item5d2925ce91#ht_1862wt_1137
I think I will be trying to return this for a full refund since there appears to be a design flaw. Normally I would attempt to make something like this fit properly myself but if I failed then I'd have a piece of junk that I could neither use nor return so I think better just to return it without messing about.
It's a shame as the cover actually looks like it should fit perfectly, and seems to fit very well, it's just that it fails completely to latch in place on one side, as if the clip bit is not long enough perhaps.
What concerns me slightly at the moment
Just reformatted the card as Fat instead of NTFS and loaded my files back on and it works now.
So I'll update in due course once I've been using it loaded up again.
My NC locks up/ freezes semi often. Usually like 2-3 times an hour. Restarting always fixes it but its crazy frustrating. It did it on phiremod and on cm7. Right now I'm on Cm7 nightly 108 and dagrins oc newest. It freezes are random times and while using any number of apps. I can not find a common thread. Any thoughts or suggestions? Also imrunning from internal memory and I have an 8gb storage card.
The most common reason for having FCs in the NC is due to the SD card. Generally, the newer/fast (class 10) type cards create issues for us. It has to do with the speed of small read/writes. The "safe" zone is to get a class 4 or class 6 card (I run with a 8GB class 6, also a 4GB class 4 - and both haven't given me any issues).
the other issue might be over-clocking. If you're kicking up the CPU speed beyond the 800 MHz, you will start making the system more unstable. If you had an iffy card to begin with, the problem will now seem more aggressive.
You could try reducing your max CPU (settings / cyanogenmod settings / performance / cpu), or replace the SD card with something that falls within the NCs stable range (class 4 is a good point to start with).
I've also found that the NC can have a poorly seated SD card and it cause all kinds of FCs or lockups.
When I do a backup of my SD card with Win32 imager, and then put the SD card back in - there've been 2-3 times where, on bootup, the whole environment just flakes the hell right out. Powering off, and reseating the SD card fixes it right up. So, my guess is my NC has a crappy SD card reader in it, or the seating of the SD cards is fairly sensitive.
You could always try that, too.
Ya. I havent been getting force closes really. Just the lock ups. I'll try a lower setting for the CPU see if that helps. The card that's in this is a like 3 year old 8gb one. I assumed it would be a lower class card. How can one discover what class the card is?

Sometimes on the card, and always on the packaging, is a small C with a number in it. That's the class of it. If it's a few years old, it's probably a class 4, which should be fine.
You're probably running into hiccups with overclocking, would be my next best guess.
Ahh, There it is. Class 4, Yah even after removing the overclocking it still freezes. Hmm.
It may help to get rid of any unused apps. I've had apps from some of my downloading sprees that have caused problems even when not using them. Clearing those first is a good step to finding the one causing the problem. This is just based off my experience.

He makes a good point - something in the background may be causing you issues. I'm constantly cleaning house on mine - I'll download a neat app, then hate how much more my battery drains.
Is the card (that you are using) a SanDisk card?
Other brands (Lexor, Transcend, Samsung, Kodak, Toshiba, etc.) are ok for camera, but are not recommended for NC.
I think I finally got it. I did the new nightly CM7 and cleared data, devorac and such. So a full on clean install. And the card is a Kingston. But all probs are fixed looks like now
If I may add my $0.02... I've heard a lot of people say that class 10 cards cause instability and you should use class 4. My experience is the opposite. I started out using a class 4 and although I was excited about having CM7 running on my NC, it was painfully slow. Starting apps took forever. Some weren't even usable because they took so long to load, and even after they were loaded they were still extremely slow. I got FC's all the time. I decided to buy a class 10 card off Amazon (I don't even remember the brand) and it was seriously like night and day. Everything runs so much smoother and faster. Some apps are still kind of slow, like Yahoo Mail, and Facebook, but for the most part the experience has been very positive for me.
Hi, I've have my VS995 for a while and it's been running perfectly. I'm currently rooted, running Alpha Rom (1BA revision) and the mk2000 BTTF Beta 1 kernel. In the last month or so I've noticed anything that has to hit storage -- either internal OR SD-- is starting to get really slow to get started. For example, if I am opening the camera, it takes a while (5-10 seconds) to open because it's reading the gallery.. if I am reading through Twitter and saving some pictures, sometimes it takes so long to save it crashes my Twitter client! But then once I get a successful save, everything is fine for a while -- but if I stop using it, it goes back to sleep. I.e., once storage is being accessed, it seems fine for a while-- if I start skimming through the gallery, open the camera back to back, save a group of files-- everything is fine. But if I let it sit for a minute or so, I'm back to super slow access times. It's almost like waiting for a spinning disk hard drive to spin back up after being asleep. Because of that I'm thinking it's not likely to be a hardware fault, just a setting or something is messed up.
Can someone point me to where to even start troubleshooting this? Since it happens on internal storage too I don't think it's anything with my SD card. Is this likely something in the kernel or the ROM itself? Could it be like a setting in the kernel? I've tried all of the different IO Schedulers with very little difference...
Thanks!
SD-Card going bad?
If it is a SanDisk, that would be my bet. I have had so many problems with SanDisk Media on many different devices and computers I gave up on SanDisk...
Yeah, I've had tons of trouble with Sandisk (and avoid them entirely, they're the only brand that's ever flat out died on me-- and multiple times!) but this seems to be impacting ANY storage access, not just the SD card... I guess I could try it with the card out entirely just to see what happens... (it's a Samsung 128gb EVO-- I almost always go with their Pro cards for phones but I bought this when Pro disappeared for a few months)
