[EVO 4G Accessories] jasongthang:
Are you asking about higher mA chargers for the purpose of charging the stock OEM battery faster, or for being able to simply charge a higher capacity battery?

Does charging the battery faster have any negative or positive affects on the battery or battery life? Because I seem to remember posts talking about the differences between charger the evo with a stock battery from the wall charger vs charger from a usb on a computer. The wall charger would charge the battery much faster, but seemed to drain faster also. With the usb charger, charging took a longer time, but some were saying that it also lengthened the battery life (charge cycle). Now I don't remember if those were completely accurate results, but I suppose it made sense. But if it was true that a slower charge made for a longer battery life, whats really the difference? At that point, does it come down to battery/cell structure? Because electricity is electricity, for the charger its all dc. So how is the charging rate regulated when plugged into the computer?

These are just things that this thread has made me think of. My conclusion though, is that in regards to battery life, any fixes would all on the software side for now, at least if we are using the stock 1500mA battery. And every 10 people on this board have 15 different ways to increase battery life, whether through a certain rom or what-not.

I also read in another post, that battery technology is not advancing as fast as cellular technology is. So at the end of the day, we have an awesome phone that can literally do almost anything, shorter battery life was to be expected. But its no where near as bad as people were saying it was before june 6th (public launch date).
[EVO 4G Accessories] lovethyEVO:
Just to throw in my .02 cents here...

The battery capacity of 1500mah is hardcoded into the evo's system.

This means that even the sprint extended battery suffers from the flaw of not being charged properly in the evo just like the seidios. I own the sprint extended and the seidios and they both demonstrate the same charging flaw while charging in the evo.

The hardcode is seen while the phone is on. While the phone is off it's possible there is some sort of hardware limitations imposed to keep the full battery capacity locked at 1500mah.

I have been looking into a way to possibly overwrite this hardcode on a rooted evo but so far my efforts have been null.
[EVO 4G Accessories] Brandito:
i believe temperature greatly effects charging and battery life as well.

my makita power tools have a 30 minute rapid charger and in order to get such quick charge times it uses a fan to cool the battery during the charge. the charger includes circuitry to slow down the charge rate if the temperature can't remain cool enough as well.

lithium ion batteries as well.

just shows ya, the batteries likely could charge much faster, but you'd have to incorporate some extra cooling so they don't get damaged.

i'd imagine the OP's assumption is about right.
[EVO 4G Accessories] PGRtoo:
The stock Evo battery pack contains a single 1500mAh 3.7V lithium-ion polymer (LiPo) cell. I haven't actually opened one up, but the larger "extended" battery packs probably contain a pair of 3.7V lithium-ion polymer cells wired in parallel which, for all practical purposes, is the electrical equivalent of a larger single cell.

Regardless, LiPo cells don't care whether you charge them slowly or quickly (within reason). There is no electrical or chemical reason why a LiPo that is charged slowly will release it's energy any differently than a LiPo that is charged quickly. The only difference might be that one which is constantly charged at a maximum rate may not be capable of as many charge-discharge cycles before it loses significant capacity. That, by the way, is what the phrase "cycle-life" refers to: The number of charge-discharge cycles a battery is capable of before it wears out.

And neither the internal charging circuit in the Evo or the Seidio external charger will charge a battery at anywhere near the most widely accepted maximum rate for a LiPo (1C). If they did they would charge a dead battery in about an hour.

Got LiPos?

Here are just a few of mine. The big ones are out in the hangar (garage).

[EVO 4G Accessories] lovethyEVO:
Those deans plugs piss me off sometimes. R/C enthusiast I take it.
[EVO 4G Accessories] PGRtoo:
Actually, Makita uses LiMn (nickel manganese based cathode) in their "Li-Ion" power packs. They're good cells and they're technically in the Lithium-Ion family of cells, but they share almost nothing in common with lithium-ion polymer cells.

There are plenty of new battery technologies either currently available or in the pipe which have superior energy density to LiPo cells, but none of 'em can be manufactured in a thin flat form-factor like LiPo cells can.

Pete
[EVO 4G Accessories] PGRtoo:
What was your first clue? My avatar? :D

Actually, I haven't been an "enthusiast" for years. Now it's more like a rabid obsession. :o

And I've been using LiPos in my planes and electronics projects for a lot longer than the cellular industry has. When I started we even had to design and build our own chargers because there wasn't anything commercially available yet.

Exciting times, those ...

Pete
[EVO 4G Accessories] lovethyEVO:
Avatars dont show well on my evo when browsing these forums. I know what you mean with the rabid obsession. I was putting so much money into all 6 of my racers (truggy/buggy/truck nitro and electric on road) that I had to take an extended break from it. That and my kids came along :p. I too remember when there weren't any chargers for lipos when they started to hit the electric scene. I have seen maybe two cars burst into flames while they were trying to charge them. Too bad we don't have peak chargers for our cells like they do in the r/c industry.
[EVO 4G Accessories] PGRtoo:
Actually, the CC-CV charging algorithm used for LiPo batteries is much more accurate and foolproof than a delta peak algorithm. Detecting a 4-5mV per cell delta in a multi-cell NiMH pack is a crapshoot at best and I actually get better results by using a temperature probe and terminating the charge cycle on temperature rise. I still use NiMH receiver packs in my slope and dynamic soaring gliders and that's how I charge them when I charge the packs in-plane.

And I've been known to use my R/C chargers to charge the Lixx packs for my cameras and other consumer electronics with easily-removable packs. I have a pair of Hyperion EOS 0615i DUO3 chargers on the bench and they're as sophisticated as programmable multi-chemistry chargers get. I don't make a practice of doing that with my cell phones, though, because I refuse to pull the phone out of the case and remove the back every time the battery runs low. That's just too much of a hassle to do routinely. Thankfully I use my phone like a tool instead of a toy and my daily use habits are served quite well by a 1500mAh battery.

But I would use an extended battery for the prudent reserve if it wasn't so problematic.

Pete
[EVO 4G Accessories] lovethyEVO:
My solution to the extended battery charging issue: http://xdaforums.com/showthread.php?t=786101

As for delta peak chargers, if you notice I mentioned I used to race nitro's and some electric on-road.

At the time, lipos were still hitting the electric on-road scene and so to delta peak charge a nimh pack was more convenient than having to fiddle with charging lipos in general.

Same goes for the reciever packs on my nitros. I was only using an 1100mah nimh 5 cell pack and so I only needed to peak charge it once every 10 - 12 tanks (which equates to about 3 - 4 10 minute mains).

I think we both agree that the charging methods we normally use in the r/c world can't be easily translated over to the cell phone industry but it sure would be nice. :)
[Fascinate General] ktez:
I was curious if there is an easier way to remove a theme other than doing a nandroid restore. I have been trying out several of the themes and each time I want to remove it I have to restore and it takes forever. I want to try more, but dread the thought of another nandroid restore. Any simpler methods?
[Fascinate General] ktez:
Anybody? I found another one I really want to try .......
[Fascinate General] themobijew:
i just apply the new theme on top lol
[Fascinate General] dlongb13:
There are stock themes in a few threads on here man, just search before you ask a question like this.
[Fascinate General] ktez:
Thank you and sorry I read these forums all the time and I don't remember seeing a stock theme but I will search tonight.
[Fascinate General] ktez:
Well I did a search and I don't see any stock theme, the only thing I saw was one person said they just used Odin. If I did it that way, would I just use the system file then?
[Fascinate General] ksizzle9:
System file should do the trick. I thought that flashing the system file would do a wipe but it doesn't. It will just put all your vzw **** on there
[EVO 4G General] WrlsFanatic:
OK, we've established that many new EVOs have the new camera, and thus need updated drivers to get their EVOs to work. I can't believe there's not already a single topic about this, but I'll gladly start one and put in any work that I can to figure out how to fix this problem.

Is there any way to break down a stock EVO's files to find the right camera drivers? Can we then flash those onto Cyanogen to get the camera to work?
[EVO 4G General] nukedukem:
I think you would need the source from HTC to get it working in Cyanogen. I don't think it has been released yet.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Solbrig:
Hi guys,

I'm running Mdeejay Froyo Zv.1.0 on my HD2.

No problems, except for some app icons not showing oon the home screen (just the text, which somehow restore itself).

A very small problem is also the fact that in Skyfire browser, the special video option is not woring. I can watch the video because of flash 10.1. Does have something to do with html?. It would be perfect if the camera would work.

There are some apps that I really would like to try. Like augmented browser or navigation.

Otherwise Froyo works very well.

Thanks for that.

[Nexus One Q&A, Help & Troubleshooting] ROM_Guest:
Hi all,

Does installing Cyanogen Nightlies erase the whole phone? How about when a new RC comes out?

Also, the Cyanogen Nightlies thread is 133 pages long. Is there any quicker way to find the latest nightly?

Thanks guys!
[Nexus One Q&A, Help & Troubleshooting] thecheatiscool:
I'm not sure what you mean by "erasing the whole phone." If coming from a not-cyanogen rom, you probably should wipe everything. If you already have cyanogen 6 installed, all you do is flash a nightly and you keep all of your stuff. Also, you don't need to look through all the posts on the thread, just click on the link in the first post for a list of all the nightly builds.
[Nexus One Q&A, Help & Troubleshooting] ROM_Guest:
Thank you Thecheatiscool!

Also, when 2.3 is released, does upgrading to that overwrite "my stuff"? :)
[Nexus One Q&A, Help & Troubleshooting] Memnoch30:
It will if you install the Google release. If you wait for Cyanogen to release a 2.3 then who knows. Probably still need to wipe depending on how much different 2.3 is from 2.2.
[Vibrant Q&A, Help & Troubleshooting] ihackall:
Today received an upgrade sms on my Samsung Vibrant. Unsuspecting any trouble I accepted the download and installation. The installation screen was unusual, - white progress bar in a blue box. When it was done the phone literally DIED. Black screen, pressing buttons does not have any response. The phone would not even power up for me to be able to do any of the fixes. It is completely DEAD. Any solution to my problem? (Except throwing it into the dumpster):)

TMO's OTA bricked your phone, they may have some responsibility. Check with you local retailer.
[Vibrant Q&A, Help & Troubleshooting] koko2k6:
This might help. It was posted in another thread

To get in to download mode

1. Make sure battery is out.

2. Plug usb in to computer

3. Put batter in(DO NOT POWER ON)

4. Hold vol. up AND vol. down

5. Plug usb into phone.

That should bring you in to download mode. Maybe something something wrong with the update and thats why it wont boot? Maybe the phone just wigged out and thats why it wont boot... but if you can get it in to download mode, from ther eyou can go to stock with odin.
[Vibrant Q&A, Help & Troubleshooting] Demonloki:

Samsung Galaxy S Vibrant Dead after Official Upgrade

I had upgraded my Samsung Galaxy S Vibrant (T-Mobile T959) using the official software (Kies Mini) and after the progress bar reached 100%, the phone completely died.

Now it won't even go into Download Mode. Won't charge, won't even blink a tiny bit. I think, it's completely dead.

Any ideas, fixes will be much appreciated.
[Vibrant Q&A, Help & Troubleshooting] shreddintyres:
Well if you purchased the phone from T-mobile or an authorized t-mobile retailer new T mobile is at fault here. Provided you haven't rooted or done anything software wise to ruin the warranty you are fine. contact t-mobile tech support and they will send you a new phone as your phone was rendered useless after an official update by samsung and t-mobile.

Even Sprint employees don't have a direct line for them, they got rid of that last year. That being said, the EVOs were having data connectivity issues, and somehow it expanded into the Epic, Moment and Hero as well, but in a more limited scope.

[Android Software/Hacking General [Developers Only]] dcj11213:
I did some research. Im using an eris with 2.1. It took me forever to figure out some stuff and maybe i can help you with it. My device would show up as F:\ on my pc. Like me, my device wasnt woking right with htc sync. Instead of keeping your device in charge only put it in htc sync. Mine wouldnt work without that. I left htc sync on and went into recovery. Typed adb devices and finally it was there. the rest can be explained in this forum for the dualrom boot. When going into the 2.2 froshedfroyo you will have to wait awhile for it to load the first time. it may seem like it is stuck but it is not. let it do its work. and when you are running it the first time, i noticed i had no apps like the gscript to switch back to the 2.1 rom and the market place. just restart device and then you will have all the apps that were missing.

Hope this helps you

[Fascinate General] tetrismonkey:
how long is it screen "dark" have you waited to see if the system boots if you give it time

whenever you flash a new rom it can take several minutes for the 1st Boot because of all the script working in the background (at least that is how i understand it sorry not a dev.)

just try giving the phone some time to boot and if that does not work let me know i will try to help the best i can but it does not sound like a bricked phone to me (however i have never bricked my phone, even with all the roms and flashes i have done over the last 2 years)

I want to preface this by saying I have spent 4 hours trying to recover my phone and I have tried all the things suggested in the treads, including what worked for me last time.

I installed a kernal for using the buttons backlighting for notifications which apparently works on the Fascinate. My phone never rebooted from that. I tried to install Clockwork and install an update.zip or an old restore file and it would not read off my SD properly/was not effective. I then tried using Odin to flash over the system, kernal, and recovery. Still no dice. I formatted my sd and tried to install clockwork again and everytime I try to access it through installing update.zip it says that signature verification failed and the installation is aborted and does not even reach clockwork.

I hope someone can help me. I have tried everything I can think of and have had zero luck.

PS: Currently my phone will show SAMSUNG but keep looping

Did you have voodoo on your phone before you flashed the kernel?

No, I was running a deoxed .4 rom
[Fascinate General] ktez:
Are you installing clockwork through Odin? I have had problems with getting clockwork to work if I installed it any other way. It should work through Odin tho - also was the kernel you flashed with the backlight notification the voodoo one or non-voodoo?
[Fascinate General] ktez:
Also did you try wiping data? Even if you can't get into clockwork you can do it from the Samsung recovery. I would try that and then do all the Odin recovery stuff again and see if that helps - but if you flashed the voodoo kernel you will have to go thru the post on completely removing voodoo.
