Update.

So I could not get sprint lovers to flash. I tried flashing both ways with both roms (full you flash from the bootloader and simple without radio from recovery) and it failed both times. I went ahead and flashed the rooted stock and tried the ##3282# and the dialer locked up.. home button worked, the pull down worked, the dialer didnt work. So i waited about 5 minutes and still no menu or pop up or anything like that. What am I doing wrong.

Edit: Speed test shows 0.5-0.7 down 0.5 was in my apartment 0.7 was out in the open in a known location to get great 3g signal.
[EVO 4G Q&A, Help & Troubleshooting] jewster07:
try restoring it back to sense on clockwork mod. and do the tweak. after let the phone reboot. Let it do its hands free Activation. and afte that you shoul hav 3g on cm7. worked for me a few hours ago. i got 1.5 mbs in miami florida with 3 bars of 3g on cm7. very happy =]

What is the best profile for this phone.. I changed mine to deadline with galaxy tuner.. Seems better than default.. But I think there are others. I remember seeing more in the oclf days.

Don't know for sure what's best, but I used BFQ after trying out SIO. I had intermittent hangs with latency timing dependent camera using CFQ.

Did not bother with others as they are old obsolete scheduling techniques.

There is a thread somewhere (Nexus One forum maybe?) where the users tested out 4-5 different IO Schedulers and found that none of them were any better than the other on a phone. The problem is that the flash memory supports read/write operations at a much higher rate than what the system can throw at the memory, so you get relatively the same performance from each of them.
[Nook Color Android Development] ace7196:
Greetings Devs.

I found this software which promises to charge i products faster. So why not the nook? I know it works with the ipad/iphone/itouch, but not the NC (or anything else for that matter). I was looking in the ini file and managed to match up the class id of each product, and then I found the id for the NC and added this line:

HKLM, System\CurrentControlSet\Control\Class\{3f966bd9-fa04-4ec5-991c-d326973b5128}, LowerFilters, %REG_MULTI_SZ_APPEND%, AiCharger

To both the install and uninstall filter. However, I cannot tell if it pushes extra power to just the ipad, or if it does to all of them.

Ideas? Tried digging around the sys file in hex, but nothing found. I think it would be nice if we could boost output a bit :D
[Nook Color Android Development] khaytsus:
USB Standard is 500mAh. If you somehow force your port to deliver more power you could fry it.
[Nook Color Android Development] ace7196:
Well yeah, but no one is at least curious if this could help out at all? Maybe hardware manufactures cap it @ 5V, .5A and they override it? Maybe it provides a steadier draw somehow? Maybe they draw more power from the rails for powered-usb slots?
[Nook Color Android Development] chisleu:
Charging more than 500ma through the USB hardware is bad.

Lithium batteries charge at full amperage over the entire charge cycle, and just turn off the charge when they hit a certain voltage (~3.6v per cell on lipo IIRC?)

I don't think there is anything you can do from the computer side unless it tells the device itself to pull the full 500ma when it would try to pull less (for fear of overloading a USB interface, as there are usually 2 ports per USB port on a computer (IIRC.)

IMO, just use a powered USB hub?
[Nook Color Android Development] lafester:
Winmo custom roms had a quick-charge feature built in to a lot of them.

I don't think anyone fried anything.

This thread belongs in QnA though unless the op is actually developing something.
[Nook Color Android Development] Syco54645:
Did any naysayers even bother to look at the link? It is for Asus brand mobos only. And only certain ones are supported. Surely Asus isn't going to release an app that would fry the port...
[Nook Color Android Development] ace7196:
Thinking of developing the software for it...
[Nook Color Android Development] Infraded:
As pointed out here, this is not JUST simply software. This is the software portion of a hardware feature on Asus motherboards. The boards have a separate controller in them that allows more amperage to specific USB ports for the purpose of charging particular, high amperage items (ipad, iphone) only. As also stated here, the USB standard is a fixed 5V .5A and this isn't something that can simply be modified via software as the controllers themselves would have problems managing higher draws (not really the physical ports).

The only application this would have would be to users with those specific boards IF the software can be hacked to allow that amperage on the Nook. It may also be worth mentioning that the Nook's internal connector is different and the higher power provided by the wall charger is not over the standard USB VCC pins on the connector. I'm not familiar enough with the wiring inside the device to say for certain, but the standard charge connections from USB may be a different path than the wall charger on a charge controller.

Quick Edit: This actually doesn't appear to be the same as their hardware specific version, which most likely makes it even less useful. It looks like this enables charging in multiple standby modes and most likely forces the port to full amperage; which is typically only done after the device negotiates with the system, initial port power is much lower. My device manager shows the Nook pulling it's full 500mA already, so unless you're trying to do a lot of charging while your computer is in standby, this isn't gonna be of much use.

Edit 2: Quick bounce around the internet shows this app as causing a bit of instability and BSODs. May not be everyone, so if you're still testing this let us know if you're stable.
[Nook Color Android Development] chisleu:
You have to use the nook's cable to quick charge. I believe it's the same on the USB side but different on the NC side.
[Nook Color Android Development] ace7196:
Thanks Infraded for the helpful reply. I did a quick search and it seemed it caused more trouble than it's worth (BSOD, etc). I'll dig deeper.
[Nook Color Android Development] mycomputerisjunk:
I had the same issues with my iPad. If your motherboard vendor supports it, they have a BIOS update that adjusts the USB ports to charge things like the Nook and iPad.
[Nook Color Android Development] combustiblemonkey:
Some dell laptops (my 5400 has it) have an option in bios for USB Power Share, where they allow USB devices which know if they are connected to to wall chargers or USB plugs to charge as if they were on wall chargers.

Its epic win.
[Nook Color Android Development] mthe0ry:
In the NC teardown, didn't they discover that the Nook Color actually uses a custom micro USB connector which is backwards compatible with the standard? It goes on to say that the NC charges only through a pair of 12V pins on the USB cable that is provided with it out of the box, and in fact when you connect your NC to your computer it is *not charging at all* even if your ROM says it is. This is consistent with my experience where the battery only goes down when plugged into my PC.

Needless to say you would need some pretty serious hardware hacks to get your PC pumping 12 volts to the USB cable.
[Nook Color Android Development] deadbot1:
Um, no. The wall charger puts out 5 volts @ 1.9 Amps. Take a close look at the bottom of your own charger...specs are right there. Supposedly, the nook will only charge when the amperage is at least 1.9 amps. In practice it will charge as much as can minus the current it is drawing...usually more than a standard port can put out(.5A).

ie standard port = .5A

Nook draw is ~ .45A

total for charging is .05A....barely noticeable or in worst case not even enough to keep up.

Not to mention that many ports shut down entirely if they think they are sending out to much current.

send 12 volts into your nook and you will have found one of the few ways to brick it:D

edit: what these"hacks" for the usb ports do is raise the limiting on them to higher values..say 5 volts @ 1A or rarely 1.5A
[Nook Color Android Development] ace7196:
Two of SMSC's family of transceivers supports up to 1.5A from dedicated charger ports.

Furthermore, I'm charging my nook color from my netbook right now with a standard non-OEM usb cable. So I don't think you need the standard one :)

Some basic info here:

http://www.smsc.com/media/Downloads/Product_Brochures/usb333x_334xfs.pdf
[Nook Color Android Development] deadbot1:
Yeah, I'm thinking that the extra pins in the stock cable are mostly for the led in there. Going back to work monday and ordering a spare for teardown purposes with my first check. I'll let you all know exactly what I find out.
[Nook Color Android Development] khaytsus:
Except that it does charge on ANY source. If the NC is running and active it uses MORE CURRENT THAN 500mAh, so it won't charge any, but it's still getting 500mAh of juice.

If you turn off the screen, it'll slowly charge.... Around 10%/hr.

And I suspect that the 1.9A from the stock charger+cable comes from all 3 pairs, the standard pair + the two extra in the B&N cable, but it's possible that the stock cable only charges the extra two pairs. Regardless, it does charge from a standard cable on any USB port. The B&N ROM does not show charging unless it's charging at 1.9A.
[Nook Color Android Development] skwalas:
I can also confirm nook will charge off a standard USB (at least while I've got CM7), using the stock BN cable, and definitely faster than 10%/hour. Have been doing so off my work computer for a while now. I recall that this did NOT work while the NC was virgin unrooted, however, although occasionally there'd be this weird "bump" in batt level to 100% when first connecting. Have not seen that effect since going to CM7.
[Nook Color Android Development] deadbot1:
last night as a test I let my nook go to 10% remaining. Then I used my daughters LG Ally cable on the stock charger for 1 hour. It charged to 24%. Then I drained back to 10% and used the stock cable for 1 hour...result?....44%. There IS something special with the stock cable. I don't think there is any magic to the charger other than the amperage.
[Nook Color Android Development] khaytsus:
Uh.. Yeah. As said a hundred times, the cable has 4 extra pins for charging on the MicroUSB side.
[Nook Color Android Development] chisleu:
No. My nook cable will not plug into my phone.
[Nook Color Android Development] deadbot1:
no, it won't. The Nook cables connector is physically longer. The extra pins make contact further inside the Nook to provide special charging functions. The standard pin layout is further back to maintain compatibility that way. I guess I wouldn't try to plug a Nook cable into anything other than a Nook...might deliver power were it isn't wanted:eek:
[Huawei Ideos X5 U8800] ryronz:
My phone will randomly stop sleeping, this has happened pretty much since i've gotten it.

I will launch spare parts, running near 100%. Check partial wake lock, nope nothing. And nothing under any of the other menus in spare parts that would indicate it not sleeping. This will occur after a couple of days even after installing no apps, restarting does not fix, neither does pulling battery. It will just start happening and only way to fix is data reset / factory wipe until it happens again, but when it does start happening I might've not even be using it at the time.
[Huawei Ideos X5 U8800] ryronz:
Okay, i did actually finally fix it after months without factory reset, it appeared to be when 3g and Data-always enabled was ticked.
[Huawei Ideos X5 U8800] the red krawler:
If this fixes my no sleep problem, I will name my first child after you.

I've been detailing the steps I've taken to resolve my no sleep issue on another forum, with the last action I took being a flash to factory ROM from huaweidevice.com, changing absolutely nothing on the phone for 24 hours, rebooting, and waiting another 24 hours. Without a reboot between charge/taking off charge, it would be 100% running. If I took it off charge and immediately rebooted, running would be more like 30% (ie: 'normal').

I'll give 'data-always' a go :D
[Huawei Ideos X5 U8800] ryronz:
Wooh, nah for example my running time is 8.7% and screen on is 6.1% so that is pretty good, thats over the course of about an hour :)
[Huawei Ideos X5 U8800] ryronz:
Okay im unsure now, was all fine yesterday, woke up at 7 to alarm, lost 2% overnight. then just put it under my bed but now that i've woken up i've lost 18% because it just stopped sleeping again. I didn't do anything except turn it on check battery, and turn it off. So back to being confused again :(
[Huawei Ideos X5 U8800] ryronz:
Still having this problem, for example. It was sleeping fine when I went to bed then at some point during the night just stopped.

Running 64.6% 10h

Screen on 10ish% 45 minutes

Highest item with partial wake lock in spare parts is like 5 minutes, no other indicators.

This is happening no matter which ROM i try.
[Huawei Ideos X5 U8800] the red krawler:
Considering a stock ROM with exactly 0 changes still has sleep issues, its clearly a firmware "thing".

For me, it happens after being taken off charge.

For e.g. Last thing before bed I check my running time, and its somewhere around 35-40%. Plug into charger. Take off in the morning, goto work etc, check my run time and its 100% even without the phone being touched.

For the moment I just downloaded one of the "root only" reboot widgets from the Market. Its just part of my morning "get ready for work" routine to hit the reboot widget and reboot my phone.

Its a bit of a PITA but until new firmware is released I cant see a way around it.
[Huawei Ideos X5 U8800] ryronz:
Hey don't know if you've tested it further than that. But its much appreciated, that rebooting after charging does seem to work :D. But just wondering, if you know... does it only do it when charging via usb (computer) or AC or does it not matter?
[Huawei Ideos X5 U8800] knevski:
I have exactly the same problem.
[Huawei Ideos X5 U8800] knevski:
I also noticed that reboot helps, but only for a while. If i want my phone to go to sleep mode when the screen is off, i would have to reboot it few times a day... Turning WiFi/GPS/Auto-sync on/off does not have any affect on this.
[Huawei Ideos X5 U8800] the red krawler:
As per your suggestion via email, I tried the Malaysian firmware.... It seemed that 'running' time was down alot, but battery life was still pretty average. That was doing nothing more than installing the Malaysian firmware and entering my Google account - no root, no launcher changes, etc.

The lack of Swype was a bit of a downer too :(

I gave it a whirl from 6:30am to around 5:00pm and 'running' was right down in the 10% range, but battery was still down to ~45% over that time in 'pure' stock form. DAMMIT!

Ah well. It was a good thought and hopefully it worked for you :) I'm back on roadhound + the OTA update as of about two hours ago.

I'm going to scour the SGS forums and see if anything there can be applied to the U8800 RE: battery life improvements.
[Huawei Ideos X5 U8800] ryronz:
Oh yeah sorry, try using something like juice defender to disable 3g when screen is off or something. 3g radio keeps it running, but it doesn't appear to be, this will stop the battery drains.

EDIT: That does work but its not ideal, turns out the u8800 and the u8800h use the exact same radio so im not sure now, don't know if there is any possible way to figure it out.
[Huawei Ideos X5 U8800] knevski:
Sometimes i have 3g data connection running, but phone goes into the sleep mode when screen if turned off. So this is not the cause.
[Huawei Ideos X5 U8800] ryronz:
Oh no, this is just the case for the U8800H malaysian firmware seems normal for all U8800 firmware.
[Huawei Ideos X5 U8800] knevski:
I'm not using u8800H firmware and i have this bug.
[Huawei Ideos X5 U8800] astewart:
Hey guys.

This may not really be the thing you need but I was having similar problems and running 100% on without sleeping etc and came accross another forum where this was an issue (cant remember where)and as trivial as it sounds the solution for me was to go into settings/ applications/ manage applications and running applications and go down to media storage and clear the data. I do this now and then when I have this problem and it seems to help.... Maybe worth a try? It seems to be an issue with a particular media file. I also try to reboot my phone after every charge. Note that my phone is totally stock
[Huawei Ideos X5 U8800] knevski:
Thanks for advice, but unfortunately this didn't help either. For some unknown reason, my running time is again 100% although the screen is off most of the time. In Partial wake usage, Android System is in the top of the list.
[Huawei Ideos X5 U8800] ryronz:
Oh, Android System partial wake lock seems to be a different issue, but maybe someone can help you out. Whats happening here is running = 100% yet there is no partial wake lock held. Quite unusual
[Huawei Ideos X5 U8800] knevski:
Yes, it is confusing also because i have tried different ROM's with same result. I would have thought that all u8800 owners have the same problem.
[Huawei Ideos X5 U8800] sprkrt:
same problem here...
[Huawei Ideos X5 U8800] andreasha:
Try do a clean install and maybe try 137?
[Huawei Ideos X5 U8800] knevski:
I'm experiencing same problem also with B137. I did clean install.
[Huawei Ideos X5 U8800] katu2006:
Can anybody get more than 24 hours of one battery charge?

With my old Iphone 3g, with Bluetooth and Wifi On, I used to get 2-3 days in one charge... I would assume that after 3 years, the hardware has improved. Huawei is advertising this this phone going for 370h standby...But in reality it's only 24, if you're lucky... :(

Hopping 2.3 will make a change otherwise...it's gtg...:(
[Huawei Ideos X5 U8800] ryronz:
Well im hoping some AOSP roms will fix it, because maybe its a buggy driver or something (if AOSP is actually different code, im not sure)
[Huawei Ideos X5 U8800] knevski:
I guess it is buggy driver that causes this. For example void. 2.2.2 #andromeda ROM also has this same issue. I have tried at least four different ROM's, and in each one of them phone randomly stops sleeping.
[Huawei Ideos X5 U8800] katu2006:
I really don't understand how this type of MAJOR issues go out into production...But I guess, as far as phones industry is concerned, Huawei hasn't reached maturity. I know for sure that Froyo works fine on other brands, so it's definitely something to do with hardware/drivers...:(

Gingerbread is my last hope...
[Huawei Ideos X5 U8800] knevski:
I'm still wondering, is it a MAJOR issue or not. There seems to be quite many U8800 users, how are not complaining about this. Are they not experiencing this problem, or are they just unaware about it?
[Huawei Ideos X5 U8800] katu2006:
I think everyone just puts up with it or they just don't care how fast the phone discharges...you just recharge every night... :( just like 5 years ago :))
[Huawei Ideos X5 U8800] ryronz:
I believe that is because these ROMs are not compiled by source, but are instead using the same library and drivers as all the stock ROMs. That is why a ROM that is written and built completely from AOSP code would most likely work better, but for that we need quite a few developers.

In saying that, I do believe this actually seems to be caused by Media storage, I find that when its running 100% and I restart it needs to rescan the SDcard (but it doesn't if I restart when its functioning normally). This leads me to believe that the media storage driver is crashing and causing the phone to not be able to sleep. This frequently happens for me when taking pictures or listening to music. I'll try a few days without using a SD card and see how that goes. Thanks guys.
[Huawei Ideos X5 U8800] knevski:
Thanks, i'm starting to believe this also. Usually when i unplug the phone from charging, it stays running 100% after that, and only reboot helps. Now i unmounted the sd-card, and plugged/unplugged the phone from charger few times and every time it is sleeping correctly when the screen is off.
[Huawei Ideos X5 U8800] katu2006:
Thanks guys, I think you're right, the media side is causing some sort of crash/hang and the phone doesn't go to sleep, but I don't understand why isn't anybody doing something to solve this issue...Surely somebody reported this to Huawei, but nothing so far.

I'm not a developer, but I've tried multiple ROMs, from 133 to 137, 158, 160 etc...no change what so ever, 1 out 5-6 times it goes to sleep it happens again. It's very easy to diagnose too, you let the phone over night and it looses 2% of the battery, but after some usage during the day, you lock the screen and come back after 1-2 hours and it's lost 5-10%. :(

Opened to any sort of testing/installations if anybody has any ideas.

Cheers
[Huawei Ideos X5 U8800] petrsiri:
Solving this problem should definitely become huawei's number one priority in an upcoming update...
[Huawei Ideos X5 U8800] knevski:
After using over 24hrs without sd-card, this problem came back. So maybe it is not the media storage driver which causes this..?
[Huawei Ideos X5 U8800] katu2006:
I've tested that theory too and it's still happening. I've got a new idea now...I believe it's to do with widgets, as I've switched all widgets off and it seems fine so far, around 5% loss over night and with moderate usage 20-30% during the day. Not sure yet, I'll have to test it for a couple or more days...

Could it be one of the stock widgets that hangs and runs the whole time the screen is locked? Maybe Power Control or News&Weather?
[Huawei Ideos X5 U8800] knevski:
I'm not having any of the stock widgets, and i'm using LauncherPro as a launcher.
[Huawei Ideos X5 U8800] katu2006:
So no widgets at all?
[Huawei Ideos X5 U8800] knevski:
Beautiful Widgets, LauncherPro People&Bookmarks and Latitude.
[Huawei Ideos X5 U8800] katu2006:
Hmm, I don't know...I wasn't using any of these.

Can you do a test without any widgets?
[Huawei Ideos X5 U8800] iakoboss7:
can you tell as what it says at the battery usage screen of android when it IS happening and when it is NOT? is there any difference?

like what apps it reports and at what percentage!
[Huawei Ideos X5 U8800] katu2006:
Running B160 Stock ROM. When the problem occurs, the stats look like this: Android System ~85%, Dialer ~3%, Cell Standby ~3%, Bluetooth ~3%, Wifi ~3%, Phone idle ~1%.... Lost the whole battery in 23h.

When it's not happening the stats are showing Android System 60%, Dialer 19%, Cell Standby 6%, Bluetooth 6%, Wifi 6%, Phone idle 5%...Lost 11% in 7h...

Would have been nice to have the full stats like on 2.3.4, that shows Display and others...:(

Attached print-screen with the case when it hasn't happen...yet...
