Hi everyone!
Have anybody ever tried to increase RAM memory by decreasing ROM?
I used to have Qtek 2020i and it was possible to distribute free memory among RAM and ROM on that device...
What about HTC Trinity?
no that changed when wm5 came and devices started using
flash as storage rather then ram like on wm2003 devices
since when does RAM store files? RAM gets erased after a device turns off and on again!!!
not in old wm2003 devices but hardreset or batt death cleared all ram
== all storage too
because flash was not used back then
I guess that's why they had backup lithium batteries onboard.
The onboard battery is used for keeping the alive the RAM, which holds your precious data, in pre-WM5 devices, in case of changing batteries and/or SIM, or when the main battery runs out.
But the battery isn't just go away with WM5. Many devices, including Trinity still have a battery. But it is probably solely used for time keeping.
that why soft Memmaid can't function well...
i mean the bar to decrease ROM and increase RAM.....
poor...i play a game on P3600 not very fast as some kind of PDA ...

Whenever i change the phones battery if i take more than 30s or so the ramdisk loses all its data? is this supposed to happen? if so is there a way to simply reduce the ramdisk to 2-5 mb so that i can install everything on the device itself?
with wm5 ram stoped being used as storage because it loose it's data when the batt was pulled
with wm5 6 only flash is used for storage and because himalaya dont have that much flash people use ramdisk to get more storage
if you dec the ramdisk size you get more app running memory but not more storage
but there is pagepool for apprunning, ram disk which is supposed to be the RAM area for new devices i think, n storage which is supposed to be ROM... the 30 mb of storage i have can have programs installed on it... n so does the 30 mb ov ramdisk...
no pagepool is more kinda like cache
RAMdisk is RAM. By its nature RAM is volatile. WM5 and WM6 make it a lot less volatile by telling the OS that this area of RAM should be treated as a storage device. Although I've not yet lost a single bit from RAMdisk since I flashed my first WM5 ROM, I regularly copy my RAMdisk to SD and from SD to desktop HD, just to be on the safe side. If you loose data from WM5/6 RAMdisk, it's probably either because you short battery contacts while changing batteries or because there's something wrong with your backup battery.
WM5/6 Storage (also known as "Device" in installation procedures) is ROM, it is physically a totally different kind of chip.
All you can do by cooking ROMs is shift the sizes of RAMdisk/pagepool(indeed cache)/Program memory, but both pagepool and program memory are 100% volatile, 0% soft reset or empty battery resistant.

yeah maggy is right
and welcome back maggy
the reason people loose ramdisk at crash hardreset batt removal (it happens from time to time too ) have to do with some issues many himalayas seem to have with their backup battery
i guess youre right my backup battery seems to run out of juice very very quickly.
How do u replace the Backup battery...my pda also looses its data after a a little while....some times it also doesent starts..please also describe the kind of battery..because i tried my self and the battery is more thin than the PC Bios battery
the batt it selft should have a part nr which batt sellers worth their salt should know so write it down and ask them
but could be that the batt itself is not the only problem could also be the connector or simply the backup batt measuring system in the pda
Hi all,
I have installed the WM6.1 ROM 6.1.2a16CS by C. Shekhar on my qtek2020.
It is very cool and gave a second life to my qtek. I am just a bit surprised by the duration of the main battery. It is running out of bat very fast.
As I haven't used my qtek for month before installing the new ROM, I can't tell if it's a battery problem or because this new ROM is consuming more resources. Have you noticed such behavior on your machines?
For further info I am not using my qtek as cell phone. I am thinking about using it back as a phone, but I have first to fix this battery aspect.
Moreover I have read s/t about a battery fix, that I haven't installed yet. Can s/o tell me more about this fix and what it is doing?
Anyway this ROM is a great one.
Thx for your answers
Marc
I dont know about the battery fix but i have never installed any sort of fix like that either for wm5 or wm6.x. Are you sure there isnt some background process that keeps on continuously running? It could be a battery problem if the battery had discharged alot during the non-operational period. I changed by himas battery about 7-8months back because the last battery had gotten abit too old and was discharging very quickly.
i think you are talking about SD card fix..its a registery fix that makes the battery consumption by SD-card low
well, WM5 and WM6.x IMHO are battery consuming ROMs, i can attest to this,
experiment no. 1:
same xda, same battery (1200mAH original battery)
-with WM2003SE at normal use, XDA turns off approx after 36 hrs of use including standby.
-with WM5 and WM6.x, XDA turns off WM5-18hrs, WM6.x-25hrs of use including standby.
experiment no. 2:
two xda, different OS, both with brand new 3600mAH extended life battery.
in 1 day (at heavy texting use from 7am to 7pm):
WM2003SE XDA2 - battery from 100% to 58%
WM6.X XDA2 - battery from 100% to 35%
possible explanation:
WM6.x (WM5) uses more CPU time and Memory resources, plus it probably uses more power in maintaining the persistent storage, hard and soft reset persistent memory.
MODS PLEASE REMOVE THIS POST

Ather, is this fix already in all/most recent releases? If not, can you give us a link? Never heard of it.
I have no battery problems, quite the contrary. My battery life is amazing me. To be honest I tweaked a lot when I started using WM6.x, too much to remember, too much to tell you.
but some parts:
I don't need 24/7 phone connection, Phone Alarm takes care of this for me
Use a bare minimum of today plug-ins
Avoid animations
Close programs except when you seriously do need them in the background
Heya Maggy...its long time since i saw u here.. think maybe month
welcome back ny ways
well that fix was in the Imate website..i have it
having some problem attaching on xda : http://www.2shared.com/file/3591354/873d3f18/SD-Card_Patch.html
first of all, excuse me for my bad english...
OK, to the problem !
when i have no programs running my diamond use up around 80-90% of ram..
what can i do about that? i've closed all the programs...
Which ROM are you running? We can't help if we don't know that.
i got 1.93 wwe rom, running tf3d and have 70%. If not running tf3d - 60%.

try to reset your device and ceck the used ram at startup...
ROM: 1,97,413,3 SVE
I have reseted, and it's still 80-90% :S

Install a task manager like dotfred's and check for running processes to see what is causing this behaviour.
and i thought my 44% was bad
Guys, what modifications do you suggest to lower the % of RAM? My Diamond has 1.37.401.3 WWE Rom version, apart of upgrading the Rom, is there any other solution? Thanks in advance...
i have samo rom how much ram usage you have?
i have 70%
Just so you know, you can save 10mb of memory by turning off the phone skin, i personally prefer it turned off and its by far worth the memory savings.
I used advance config to turn it off but im sure most of the tweak programs will have the option built within them.
thx i will try but i need to update rom. i need to backup this rom but how??
and when i update rom will i lose my igo8??
Currently 64% (after soft reset), but sometimes close to 80%, even if all apps are closed...some hints on managing or lowering the % of Ram would be very useful...with Fdcsoft task manager one can see, that the largest process running is cprog.exe (9464kb), device.exe (3832kb) and gwes.exe (3589kb), others are particulary smaller...guys, is there any other way to shrink the %?
Edit: will try that phone skin option...thanks
Im using the SWIFTBL 5.0 rom, my memory as we speak is 48%
Ive applied quite a few reg tweaks though
Guess i will have to do the rom upgrade in the near future...
With disposable config apps, and phone skin off, i managed to lower the RAM to approx 55%...starting to like it now
I use Memmaid and SKtools to free up Ram if needed.....try it
Keeping things well under 60% now...thanks guys
Hi guys,
I got a simple, dumb question (sorry about that).
But If there's more memory (RAM) is used on a handheld device, will it used more battery?
Will my device work longer when the memory is 50% loaded than 80% loaded?
(both not running applications).
I hope someone can give me a good answer
****head
Of course, the more memory you use, the more power you need, etc. So yes, more used memory will cost you more battery.
Really?
AFAIK RAM IC is powered as a whole and draws constant power regardless of how much memory is actually in use from OS perspective. nevermind, can you prove your statement in any way?
^ was correct, memory requires the same amount of power whether you use 128MB/256MB or 200MB/256MB because it requires the same amount of energy to store a '0' or a '1'.
The more data you have in memory tthe more memory accesses you would use to access what is in memory because it's there for a reason.
ok Thanks for the explanation :-D
Android, is it really 'safe' to run on topaz with haret.exe?
Not really.
I know people will say "dude, dont test builds out if you are scared. I love android". I do love topaz android too. i hope this will help to prolong your topaz's hardware lifespan.
Possible hardware damage caused by buggy topaz android
1. Battery
2. sdcard
3. Possibly decrease in performance in other parts of the phone
Why is current buggy state of android harmful to topaz? Well,
1. constand read/write on sdcard with constant power supplied(never shuts off for power saving) - decrease life span of sdcard
2. Li-ion battery SHOULD NOT BE SUBJECTED to high drain situations if possible. This will decrease battery capacity significantly.Currently, battery drain is significant, due to unnecessary devices are left turned on etc.
3. Carging while high drain situation with BUGGY BATTERY METTER can stress our battery significantly even if there is protecting ic chip to protect battery from overcharging.
The problem is : Heat
Li-ion batteries lose their capacity if subjected to high temperature. Charging it is just suppling heat to our poor topaz battery, since battery will function like resistor ;D note topaz cannot directly be powered from usb. i.e. power socket->battery->topaz not power socket->topaz
4.Heat makes other parts of system subjected to lower lifespan and possibly, damage them
5. Remember android on topaz currently dont have 100 percent control over hardware, meaning unnecessary stuff can be running at all times.
Suggested way of using android on topaz
1. Have at least two batteries and swap them as you use topaz for both normal and android situations. This is good for li-ion batteries in general
2.Do not charge while you use topaz and if possible, stop it before battery is lower than 40%. In anycase, do not let it shut down because of low battery. If you really want to charge, consider downclock/full radio off/screen off to try to minimise stress battery goes through.
3. If possible, run android in cool, shady environment like your bedroom P)
4. Try to minimise running test builds like branch of test build for camera . This may stress your phones hardware unknowingly.
5. Becareful of android corrupting your sdcard anytime. Unknowingly, it performs a lot of read and write which is not recommended for flash memory in general.(sd cards are not ssd people)
6. Dont game or run benchmarks as much as possible
That is it. This guide applies to haret-android devices in general.
This guide will not be needed as much in situation of:
1. Nand build
2. Ram-mounted android build ( still danger of fring your sd card )
3. properly calibrated battery meter
provided their builds are stable and not as stressful as current build.
Happy android-ing. XD
Post your feedback. Please dont post things like I should not try it etc. This is just tips ,come on.
Yeah I've definitely thought about how bad the heat is for the battery and the phone itself
But I'm running it on a pure, so I almost don't care if I destroy my phone in the process. Would just give me an excuse to switch over to verizon for a droid or pick up an iPhone.
Good guide for newbs
I'm alxo running XD Android on my pure, but mostly just for the novelty.. Should I be switching batteries every time I want to run android? Should We all just wait for a flashable droid rom?
Does haret run on top of windows?

made by ME
Umm just to clarify
1. you do not need to set aside android battery. Just swap whenever possible even when running winmo. 2 Li-ion can last 3 years instead of 1 year for 1 battery
2. no. android is stand alone os
3. enjoy your android. Nand build is comming as DFT decided to port HD2 android boot utilites to Topaz and Rhoium. XD
4.Thanks for russian translation haha
My SD-card crashed
Hmmmm, my SD-card crashed today, and I did a lot off Android testing last two months ....
(my card is 2,5 years old)
This thread has an important warning: SD-cards are not made for this....
