Nexus S hacks MIGHT be bringable to our phones - but far less likely than GS phones.
[Samsung Infuse 4G] AdamOutler:
USB OTG mode is initiated by shorting USB pins 4 and 5. The phone can do it hardware wise. It's a matter of having the drivers for the accessory connected.

You don't just "have" OTG capabilities... It's a matter of what devices you support.

This would not be something which would occur at the device level. The hardware is connected to the phone, the phone runs Linux. Linux handles connections of the devices. Grab kernel modules from Linux for OTG devices.
[Samsung Infuse 4G] dotpkmdot:
If thats the case it would seem odd that so many developers work towards adding the support to phones.

The SGS2 doesn't have drivers built in to support connecting to canon DSLR's yet its the only phone at this point to officially support it... because it supports USB Host OTG mode.
[Samsung Infuse 4G] AdamOutler:
Check out the GalaxyS hack pack for the USB chip. I can verify that the kernel knows when something OTG is connected. It brings up UART messages and you can see it in dmesg.
[Samsung Infuse 4G] AdamOutler:

[Samsung Infuse 4G] Entropy512:
Right now USB host is not compiled in the kernel at all, so I'd expect this.

That's why I was asking if someone had found an example of a first-gen SGS with USB Host/OTG support compiled in. With an example kernel's defconfig and source I can analyze, it shouldn't be TOO hard to port that functionality to our device.

The current state is: FSA9480 tells the kernel that an OTG device is connected, kernel says "I dunno what that is. I'll give up and do nothing."
[Samsung Infuse 4G] vishal24387:
Usb otg through micro dongle

I think you people should try for this. I think it will work for ur device.

www.tombom.co.uk/blog/?p=124
[Samsung Infuse 4G] Entropy512:
No, it won't. See the posts above - there are software components missing.

Again - if someone can point me to an example of a kernel where host mode is working on a first-gen GalaxyS device, I'll try to port it over. I'm not going to try and backport anything from a GSII.

Convincing the FSA9480 to signal host mode is only a tiny piece of the puzzle - see HDMI on Rogers Gingerbread as an example.

this is an old thread. but things have changed since then. its been successfully integrated into the galaxy s and nexus s. hopefully it will result in a port since its atleast plausible now.

[EVO Shift 4G Q&A, Help & Troubleshooting] jonnythan:
I edited the build.prop to match the Evo 4G. The video option appeared and it seems to work, except I don't get video. I get the audio from the video stream along with a blank black screen.

I'm running Deck's 1.2, which is basically a CM7 variant.

Does anyone have any ideas about what the problem might be? I've uninstalled and reinstalled Flash.
[EVO Shift 4G Q&A, Help & Troubleshooting] fifedogg:
I only get audio and no video using flash 10.3 but when I uninstall and install 10.2 my videos play fine. Try that its not hard to find the .apk but if you can't I will send it to you.

Hi, I created my GC and Rooted my phone with my old MAC.

I used 'hack kit'.

My question is, can I download 'hack kit' to my brand new PC and flash my phone back to stock??

Why? I have a defected phone and I want toflash back to stock so I can get a new one!
[HTC Inspire 4G] Carlrobling:
You should be fine. I started my root on pc had trouble and completed on a mac. The process for rooting a phone is the same just different commands for the different os.
[HTC Inspire 4G] bdpyo:
I used the hack kit, I'm s off, everything seemed to go ok when flashing back to stock.

I DO NOT have any sound??
[HTC Inspire 4G] bdpyo:
And I also have side loading enabled, please help.
[HTC Inspire 4G] Carlrobling:
Download the stock ruu from htc. It will install the stock rom and you should be good to go.
[HTC Inspire 4G] bdpyo:
I did via the hack kit link for stock ruu, I didn't see any errors, but not having sound side loading enabled seems off to me...
[HTC Inspire 4G] biglittlegato:
If you're S-on and have a stock rom, turn it in with no sound. Just another defect.

Thanks to the guys in irc, I got it all worked out.
[HTC Inspire 4G] biglittlegato:
Cool. What was the issue?
[HTC Inspire 4G] bdpyo:
i ended up stuck with the downgrade ruu that has no sound, ended up running a exe via htc sync that shad0wf0x gave me, took forever, but i finnaly got it working.

returned it this morning and got a new one, installed cm7 7.0.3 when i got home :D
[Verizon Droid Charge] adlzian:
Just wondering has anyone purchased some spare batteries on ebay? I don't want any extended ones cuz i don't want extra size to the phone. I wanted to buy a spare one actually made by Samsung and a battery charging dock so i won't have to switch batteries just to charge them. I don't know if any other non-oem batteries are any good. Hopefully someone can give me some feedback or info about that. Thanks
[Verizon Droid Charge] chaoscentral:
Honestly I bought the media dock with spare battery at VZW and havent looked back since. doubles as an alarm clock, charges spare battery at the same time and i dont need to worry about fiddling with plugging in the cable, just slide it into the dock. It's very much worth the 49 they are asking since the dock alone is 39 so its an extra 10 for the oem battery
[Verizon Droid Charge] avid.aria:
I was just browsing ebay and there are some 1800mah batteries. I am wandering how true that can be though!

I purchased some of these batteries for my thunderbolt and didn't notice any difference, not sure if i want to spend that much money on sth like this again !

It'll be good to know if anyone has actually tried these on their droid charge ...
[Verizon Droid Charge] DKYang:
When I had the Nexus S, there was a huge topic about the 1800 mah batteries from China. The result? It was fake. So I wouldn't go for those. Just stick to the standard Samsung 1600 mah batteries or the extended ones.
[Verizon Droid Charge] adlzian:
Yeah i was thinking id just go for the Samsung ones
[Verizon Droid Charge] syntrix:
Yup, just like the seido batteries on the droid incredible. Nothing but garbage but claimed a much higher rating in the same form factor. There was a huge thread on df about it where a guy ran a discharge tester with just about every battery that was sent to him.

OEM or the 2200 battery in the factory format must be new technology that the oem's haven't picked up on yet, lol lol lol
[Verizon Droid Charge] monkeyhihi:
Because I can't post links yet, I unfortunately can't show you guys the extra batteries that I have. However, if you go to Amazon, and search "Hyperion Samsung Droid Charge i510 2 x Battery + Charger", you can see them.

For 25 bucks they're not a bad deal for two batteries, and I get comparable battery life to my original battery. :D
[Verizon Droid Charge] adlzian:
Wish i could have seen those earlier. I ordered two Samsung batteries and an external charger from ebay. The batteries are 1500 mah instead of the original 1600mah. So ill see how those work out...
[Verizon Droid Charge] zylandros:
I got the desk dock that another poster got from VZW. Fortunately, I got a 25% discount because of my company.

I had a bad experience with ebay batteries on my DX. The one I got on that will only charge in charger that came with it - not in the phone. And, then the phone does not always recognize that battery. Because of that burn I only buy OEM now.
[Verizon Droid Charge] adlzian:
I just got my batteries in today so ill be letting u guys know how they are. Think of it as my review...lol
[Verizon Droid Charge] pyroelite:
One of the main reasons I like having a hacked kernel is the ability to use non-oem batteries (unlike the DX) - use something like the pbj kernels that incorporate that option. & Another reason I'm waiting on making the switch to a GB rom.

{SDCharge Humb£e 1.25}
[Verizon Droid Charge] Farabomb:
I'm using the the Hyperion batteries in both the GF's Tbolt and my Charge with no issues at all. Yes the wall charger is quite slow but I don't mind becasue I figure it's not hammering the batteries with a high rate charge.
[Nook Color General] Vettesfan:
I finally got a charger for my NC and proceeded to dl the new cm7 7.1.0 RC1 after using clockworkmod to install I cannot boot up. It shows the new cm7 boot logo and then goes to a blank screen and sits there. I didn't wipe cache or data
[Captivate Q&A, Help & Troubleshooting] kb0npw:
I have noticed that when I click a button, I usually have to wait from 1-2 seconds before I get a response. Would lagfix take care of this? I'm running stock Froyo.
[Captivate Q&A, Help & Troubleshooting] little8020:
As many have stated all the lagfix does is help fix the very slow rts file system, it most likely would not help in your case.

Best thing to do is delete unused apps, and reboot the phone every day or to(seems to help mine out, cant guarantee results)

Also if you havent needed root in 5 months you probably don't need it
[Captivate Q&A, Help & Troubleshooting] prbassplayer:
Unless you want to use opitimised roms, I dont see why you would need to root. Check your memory usage delete unused apps and reboot the phone ever once in a while.
[Captivate Q&A, Help & Troubleshooting] mcord11758:
My honest opinion, no reason to have an android phone if you are not using roms
[Captivate Q&A, Help & Troubleshooting] james.arroyo:
Gonna have to agree with mcord here. had to go back to stock froyo for about 5 hours (didnt have all my tool to get back my 2.3.4 ROM) and it was horrible.

you might not be up for it but i really recommend flashing a Froyo Custom ROM from one of the xda DEVs. you'll love your phone and be amazed that it can be so much smoother and responsive.
[Captivate Q&A, Help & Troubleshooting] DARKCHYLDX101:
First thing I did after i rooted was flashed a new kernel to overclock. Performance increased but battery life was poor. Then my first rom was cm7..been hooked since..tried miui once then went back to cm7.
[Captivate Q&A, Help & Troubleshooting] godpancho:
This is what lagfix can do for your phone.

Im using stock mosaic V 2.3.4 rom with no overclock.
[Captivate Q&A, Help & Troubleshooting] z28james:
Providing arbitrary benchmarks does not seem like an actual reason to employ a lag fix.
[Captivate Q&A, Help & Troubleshooting] godpancho:
No a Benchmark score is not the best example to lag fix your phone ,but the more power you get, plus better battery life and, better perrformance are great reasons to lag fix your phone. I just posted the quadrant score so kb0npw can see the increase performance from normal rfs file system to ext4(lag fix).
[Captivate Q&A, Help & Troubleshooting] diminished5th:
Lol people always thinking benchmarks scores mean everything
[Captivate Q&A, Help & Troubleshooting] Reynaldinho111:
I dont think he thought it meant everything, he was giving a simple before and after which showed some improvement. Quadrant can actually be pretty useful when trying to gauge what effects certain changes have on your phone, say you score a 1900 before you change 'x' and then 2200 after that change, then you know its increased performance somewhat and youre moving in the right direction. How much it has increased your performance is debatable, however. My point is quadrant can be a useful tool when making changes on your phone if you take it with a grain of salt.

EDIT: To answer op's question, Read up on some custom roms and flash one, the difference is phenomenal and you'll wonder how you went 5 months without them. If you have any other questions feel free to pm me and I'll see what help I can be :)
[HTC EVO 3D] fdavila17:

[HTC EVO 3D] fdavila17:
Are u guys getting good battery life?
[HTC EVO 3D] deadly3kys:
Hell No, I charge my phone for 3 hours and i barely use the phone and it dies half way throu the day. I dont even have my Wifi, 3G,4G, Bluetooth On, Even Brightness i put it to low lighting and the phone doesnt last till 6pm. I charge it in the morning (11am 100% charge - 5pm 2% left. I love this phone but the battery life sucks !!
[HTC EVO 3D] fdavila17:
Well idk what's wrong with ur phone but I'm getting amazing battery life, but i get it today so idk but has been using the phone like crazy with non stop!!
[HTC EVO 3D] knightwolf123:
Battery life is awesome! My 4g has 3500mah and my 3d has 1700mah. I use both and the 3d last longer every time! In fact, I have 3d on wifi all day and making phone calls with "groove ip" and it still lasts longer!
[HTC EVO 3D] fdavila17:
Great mine has been in 3g, WiFi,Facebook, XDA app since my las charge (6 hours ago) texting a lot too I'm it still on 65% pretty damm good
[HTC EVO 3D] deadly3kys:
hmmm.. Its shocking to me cause my phone dies quick. Well i have insurance so i think i will just get it replaced or buy another battery. I had other android phones that lasts me almost 2 days, but so far i had a bad battery experience with this one.
[HTC EVO 3D] fdavila17:
Yea something is wrong with that battery, buy a new battery and test it
[HTC EVO 3D] SouthernEvo:
On my first day I can seriously say the battery life on the 3D exceeds that of the EVO 4G .

Battery : 24%

Been running for the past 9hrs 53 mins

This is with atleast two hours of phone calls

I just spent an hour or so soaking up 3D youtube videos

Well over 150 texts sent and received today .

I spent a good part of the day playing with settings , checking facebook .

Weather (every hour) and Google(mail contacts calender) on sync

Playing around on the market .

changing notification sounds and ringtones .

My previous EVO 4G would have died long before now . If you are expierencing bad battery life . Check for any apps that might be running or causing your phone to have issues . Remember not all apps are set up for gingerbread just yet either even though most are . Use old tricks from the EVO 4G to conserve battery life . I leave 3G and gps on all the time . But if what they say is true about batteries breaking in especially after a few charges and discharges I am gonna be content with this phone as it is . I can only imagine what will be the next leap forward when devs start making kernels and roms for this thing . Seidio's extended batteries market might collapse LOL .
[HTC EVO 3D] VoXHTC:
I don't see how any of this is possible. The EVO 3D dies when you make a phone call, just like the 4G did.

I"m going to have to buy an extended battery so I can make 2 phone calls. This blows. How are you all doing this?
[HTC EVO 3D] SouthernEvo:
Something isnt right there if you make two phone calls and the phone dies , my advice is take it back to sprint and explain your situation . Either your phone is faulty or the battery is faulty . Also did you accept the updates ? Supposedly the updates include some fixes to correct a sleeping issue the phone was encountering .
[HTC EVO 3D] knightwolf123:
did everyone remember to run that battery COMPLETELY dead and charge it COMPLETELY up at least 2 times?

I did and no problemo!
[HTC EVO 3D] HammDroid:
Nope, because its not necessary to do that with Li-Ion's. Its also unhealthy to discharge a Li-Ion battery too far (although I'm going to assume this phone has a discharging characteristic that would prevent 'complete' discharge as that would completely kill the battery).

Regardless, my battery life is amazing compared to either of my 4G's (1 rooted, 1 stock gb, and even my buddy's 4G with extended battery). My absolute heaviest usage day, off the charger for about 10hrs and I still had in the upper 60's left of my battery percentage. I leave 3G, wifi, & gps on all the time. I also generally have on my BT and am connected to my headset.
[HTC EVO 3D] SouthernEvo:
I still wont forget the time a HTC Rep called me asking me my opinion of the Evo 4G . I told her I loved the phone . She asked me if there was anything that could be improved on . My response was this "Dear god put a real battery in these things , I know flip phones with bigger batteries " . She was alittle speechless at that one ROFL but apparently they listened some what LOL
[HTC EVO 3D] whatsitsnamenow:
Heavy usage to me is when the screen never sleeps. Like you are watching netflix nonstop or using the web nonstop, or Sprint tv nonstop. In situations like this all the battery saving tips will not make much of a difference since the screen on and 3g/4g radio will be on constantly. If any 3d can get 6+ hours of battery life out of it I'll buy one right away. Sadly most of the usage posted here is what I consider light or medium usage at best. Mucho texting and weather widgets is not what I consider heavy usage.
[HTC EVO 3D] -eVo-:
45% left after 21hrs. wifi on constantly, been texting, playing games, playing with 3d camera. Although it was sleeping during the night, but still pretty damn good.
[HTC EVO 3D] VoXHTC:
Live wallpaper running in on homescreen and on lockscreen too?
[HTC EVO 3D] VoXHTC:
I was being very sarcastic. it's not that bad, but my battery barely lasts 4 hours. I make about 300 outbound calls a day to clients, that doesn't include the incoming email, calls, txts etc.. syncing, GPS, sigh....
[HTC EVO 3D] deadly3kys:
dont worry am on the same boat, i barely used the phone much and i get the same problem with the battery life. I completely charge it with everything off, wifi, 3g, 4g, bl/tooth, no syncing and it dies half of the day. I think some 1st batched phones in the U.S are faulty
[HTC EVO 3D] jig_alo1:
Which charger are u guys using? I use the two in one Sprint wall charger thats also a cigarette car charger. My battery life is not great but its not horrible. I get about 6-8 hours with heavy use
[HTC EVO 3D] SouthernEvo:
One thing I do to my 3D thats a kick back from the EVO days is in the morning . I get up I unplug my 3D , get coffee and check facebook , the forums email on my home computer , While doing this I plug the phone back in to bring it back to 100% . This phone has the same charging routine as the EVO . When you unplug it , it drops sharply then levels out . It seems when I "Top off" the battery in the morning it gets alittle more mileage out of it . Also I have noticed this "top off" session is rather long . Dunno if that has somethign to do with the size of the battery or what but dont be surprised if it takes a while . Also note I get up extra early in them morning . I noticed the extra coffee saves my coworkers in the end ROFL
[HTC EVO 3D] wase4711:
put me in the group that gets amazing battery life; moderate use all day, with live wallpaper, and I still get over 12 hours of use, with 28% left at that point..

Also, wifi on, BT on..

are you turning off "always on mobile network"?

That always helps, and, make sure you set the network to Sprint only, NOT automatic..

So far, this battery life BLOWS AWAY what I was getting on my original Evo..

[HTC EVO 3D] beyond882001:

[HTC EVO 3D] BlaydeX15:
I get 6-8 Screen-on hours.

But wow... Last night I went to a party, turned off 3g, and auto sync... I woke up this morning, 9 hours, battery at 96%. Dear god, that's one amazing standby life. I also probably showed it off to everyone while I was drunk, I can't remember. :D

Just remember, if your battery life sucks, check sync settings, check brightness, and make sure it's calibrated! (Reset it, look at battery stats. If you see an instantaneous jump/drop in battery %, it's not calibrated yet. Give it some time.)
[HTC EVO 3D] Sim-X:
I have been very happy with battery life. Although I go through the phone when I get it and shut off a lot of background crap. For example I'm at 77% right now been off the charger 12h 23m with wi-fi not going to sleep (been on wi-fi about 11 hr of it). Haven't used the phone to much, maybe about 30 min of HQ rhapsody streaming over 3G and a few texts.
[HTC EVO 3D] SirJohan:
That really sounds like you have apps running for themes or desktops.

One of my phones I have on my plan has a desktop icon / theme tool that gives you an UI like sense. Before install he would get 8-10 hours of light use.

Now he is lucky to get 3 hours Tops of light use with this app running in the background.

The live backgrounds will also effect your battery life.

That is one of my first things to look for on a phone with poor battery life.

Where I work we have over a dozen Evo 4g's, 7 Evo Shifts.

Second thing to look at is the Sync for Exchange E-mail, and E-mail checking on an instant basis.

Also instant messaging apps for Yahoo, MSN, ICQ etc if they are keeping your radios alive will also kill your battery life. I hate the IM Applications that keep you online all of the time. I prefer use it when you need it and turn it off.

That is just what I can think of right off the top of my head with out seeing your actual phone, or the installed app list.
[HTC EVO 3D] fdavila17:
2nd day with the phone and still pretty good battery life, I see some people are getting great, but those who are getting horrible batter life u need to.check that up may be is a bad battery or some apps still running
[HTC EVO 3D] cds36:
Question for those with bad battery did you update your phone? I updated my first evo and had bad battery life so I took it back and got a new one but didn't do the updates installed all the same apps and I'm having outstanding battery life. Do know for sure if it was the update of just a bad battery.
