ok so as most of you know i have ben busy with the SenseLX rom... but on my spare time i would like to port a froyo rom so i can get some experience on froyo... but my question is where to begin? lol i need to find a fresh source, start from scratch!!! i dont want to use someone elses rom to make my personal changes.. i would rather port my own froyo rom and start from there... :D so can anyone guide me in the right direction? thank you!!
[G1 Q&A, Help & Troubleshooting] BeenAndroidized:
I am glad someone finally getting the right idea. :D I definately love to see the progress (when you get the original source code) and might even try the ROM out.

That is why I love my current ROM, the DEV use the original source code from google. So there is no problem attached to it from other DEV.

Good luck on this new ROM. ;)

ok so what do i do with it than?
[G1 Q&A, Help & Troubleshooting] AndDiSa:
probably something like

[Galaxy S II General] THUDUK:
I have had it plugged into the mains, running tunein radio through wifi and its gone from 85% to 86% in one hour.

If I charge from 10% with phone off it takes about 4 hours to fully charge

If I charge from 10% with my phone on running stuff, it actually never gets to fully charges by the time I finish work...at 6pm

Sorry to keep comparing to the dreaded FruitPhone, but that would charge whilst running wifi and tunein from 10% to 100% in about 2 hours.

I am beginning to think my SGS2 is faulty:(
[Galaxy S II General] buxz777:
i am fiding it takes about 3 hours to charge from empty . It does take a long time indeed but i guess it is what we have to do for a 1650mah battery :-)
[Galaxy S II General] JJEgan:
3 hours from empty with stock charger .

jje
[Galaxy S II General] THUDUK:
it might well be a 1650 battery, but it starts to get unusable when it takes all day to charge then a few hours to loose it all.

This phone is the greatest but the battery life just completely destroys it, I am beginning to think I made the wrong choice:mad:
[Galaxy S II General] THUDUK:
Is that while using it?
[Galaxy S II General] virussnake:
you are not supposed to use the phone when its charging its really bad for the battery it gets very warm during charging as it is...
[Galaxy S II General] THUDUK:
Aye...:confused: if I don't the bloomin thing would be dead by lunchtime, and I listen to music.

So I basically have to turn it off not use it so I can charge it, how crap is that, owned my iphone a year never had any problems with battery and I always used and charged in its dock.
[Galaxy S II General] godutch:
The desire had slow charging too but snq- fixed this in his kernels maybe we can port his fix to our kernels

btw it's true li-ion batteries degrade quicky when the heat up (or completely charge or discharge)
[Galaxy S II General] wetti:
From 30% it took me one hour and a half to fully charge..

I recommend to download battery mix as it takes very good statistic on the battery life and one can tell exactly how long it takes to charge and discharge
[Galaxy S II General] LBTaylor1984:
just for the record all Lion batteries in phones never fully discharge or recharge, as there balanced by a balancing chip.

when you get to the likes of 0% you actually have 20% charge, thats why you can power on the phone but it will immediately switch off again. like wise, charging you never reach 100%, it's more like 89%, again because of how Lion works.

if you fully discharged and fully recharged, well put it simply you'd have a lot of exploding phones, fire and chemical burns...
[Galaxy S II General] mariezk:
Interesting!

My phone charges in about 2,5 - 3 hours, so should be normal...

But charging with the usb cable connected to the pc it takes much longer.

Any of you experience the same thing?

greets!
[Galaxy S II General] LightspeedGalaxy:
Because:

a) That´s how Li-Ion-batteries are charged. To fully charge a Li-Ion-battery you need 3-4h.

b) The power-supply is pretty weak. It is just enough to charge the phone at decent speed, but it is not enough to charge it and intensely use it the same time. In this case much of the power is used by the phone and there is not enough left to do a proper charging. I use a 1,2A power-supply from my old Nokia, and while it won´t speed up charging itself, at least it slows down less when I´m using the phone while charging.

This is not possible. The mighty fruity-phone may tell you it is 100% charged, but certainly it isn´t

You can charge a Li-Ion-battery very fast from 0 to 70-85% you could reach this in 1h. But you have to charge the remaining 15-30% very slowly, otherwise the voltage would raise too much and destroy your battery.

The so called saturation-stage (the charging-stage until 100%) takes longer the faster you charged at the beginning. If you really charged until the saturation-stage in 1h, the saturation-stage will take 2-3h.

If you charge slower, so you reach saturation-stage after 2h, the saturation-stage will only take 1-2h anymore.

In the end it will always take 3-4h to fully charge a Li-Ion-cell, regardless how strong your power-supply is.

Another few notes:

Charging will get slower the fuller the battery already is.

Using the phone with low battery-percentage will lengthen the charging-time quite a bit, a stronger power-supply could help.

Getting the last 20% in a Li-Ion-cell will always be very slow, usage of the phone won´t influence this a lot, and a stronger power-supply can´t help.

It doesn´t matter much, how much charge is left in the battery, to fully charge it it will always take long, as you spend most of the time in the saturation-stage (the higher the left percentage is, the more time you spent in saturation-stage)

It is not faulty, it is designed this way.

It took 3 hours 10 minutes to fully charge my dog and bone yesterday whilst off
[Galaxy S II General] Regretful:
Thanks for the explanation!
[Galaxy S II General] JupiterdroidXDA:
Your having a bubble bath ain't you mate;)

Your battery sounds faulty to me, taking over 4 hours and only charging 1 percent in an hour. Try the battery calibration app in the market, if it doesn't improve get it swapped mate;)

The wifi is the killer, try turning it off when charging your phone..
[Galaxy S II General] RogerPodacter:
it takes so long to charge because samsung capped the charge current at 650 mA in the battery driver. but other phones like HTC allow charging at the full 1 amp. so that's why its a slow charge, and why its possible to drain the battery even while plugged in to the charger.
[Galaxy S II General] Idan73:
Now who wants to ask kernel developers to increase that to .850 or 1 amp and use that lol.

I believe lack of heatsink due to design is the culprit behind decision to cap it at .650.

[Galaxy S II General] gouldy26:
3 hrs to fully charge, and as i use tunein radio a lot i can tell you on my device with the screen off, wifi on with tunein running, it still seems to take no more than 3 hours maybe 15 mins more at most
[Galaxy S II General] AndroAndo:
I am probably going to order a cheap eBay Li-Ion battery that's 1800mAH and likely has a charge cap closer to 1000mAH. I will know in a week when I finally get my phone and report back if that battery helps. I expect it to heat up while charging and am going to use an external charger.

Two replacement batteries and an external charger go for about $12 USD on eBay btw.
[Galaxy S II General] fozzy169:
Mine takes roughly 3 hours to get to the magic 100% and then tells me to unplug the charger... would it damage it if I left it plugged in?
[Galaxy S II General] buxz777:
nope as it will not need charging so it will stop mate :-) genuine batterys wont overcharge due to the protection in them
[Galaxy S II General] RogerPodacter:
here is the code to change. someone really should do it and test.

if (enable) {	/* Enable charging */
switch (info->cable_type) {
case CABLE_TYPE_USB:
val_type.intval = POWER_SUPPLY_STATUS_CHARGING;
val_chg_current.intval = 450;	/* mA */
break;
case CABLE_TYPE_AC:
val_type.intval = POWER_SUPPLY_STATUS_CHARGING;
val_chg_current.intval = 650;	/* mA */
break;
case CABLE_TYPE_MISC:
val_type.intval = POWER_SUPPLY_STATUS_CHARGING;
val_chg_current.intval = 450;	/* mA */
break;

and just watch temperature readings as i think samsung limited charge current due to temperature issues. but i think it can be increased with little issue.

i wish i had a device to test, i'd compile a kernel in a second.

[Galaxy S II General] zeitgeb3r:
People, just buy a spare battery for US$25 from exporprive, clove uk or handtech uk.

If u can afford to buy a US$650 phone, a $25 spare battery is a drop in the ocean.

I carry about 3 spare Samsung batteries when travelling.
[Galaxy S II General] ivanlmh:
Well, if you have a bigger capacity battery..it bound to charge a little longer. I feel its acceptable
[Galaxy S II General] LightspeedGalaxy:
Unlikely. Charging a Li-Ion-cell can have an efficiency up to 99%, there so the charging doesn´t generate that much heat.

Besides there is a temperature-protection and the phone won´t charge if the battery is too hot.

It is more likely they limited the current, because their power-supply can only provide 700mA.

The question is, if you increase the charging-current (btw: the variable is called chg_current, do they really mean the charging-current, thus the current that is actually charging the battery? Or does it rather mean the current through the power-supply. Seeing, that they use just 50mA below the limit of each power-supply, I rather expect the last, but the variable-naming is rather confusing) will power-supplies with lower ratings still work.

But my car-charger is rated just 550mA and still works, although the phone recognizes AC-charging and therefore should limit it to 650mA. Of course this is only 20% more then the rated current, so the power-supply might still work.
[Galaxy S II General] BengalMigration:
That's good to know. I've been trying my best not to leave the phone on the charger once it hits 100% (or at least tells me to unplug it) due to fear of degrading the battery life.

If I don't need to be so concerned about this, it sure will make my life easier :cool:
[Galaxy S II General] dummy138:
Have you try to charge it with main power but not USB?
[Galaxy S II General] Idan73:
I rather think that they limited choice of power supply cause they knew that the phone can only go at .650 anyways cause both original sgs and nexus s have ac chargers that provide more.

Sent from my GT-I9100
[Galaxy S II General] RogerPodacter:
obviously the other manufacturers that charge with 1 amp also include a 1 amp charger. so samsung obviously would have included a charger larger than 700 mA. they chose that charger on purpose. they didnt limit the driver code because "oh no, all we have are these 700 mA chargers laying around". they matched them on purpose, and that purpose many people think is due to heat issues among others.

the whole point is that someone should compile a kernel and test it and see the results. i did this very thing on my nexus one. i edited the battery driver with a bunch of enhancements, compiled the kernel and flashed it to my device. tested the hell out of it, and go tthe changes incorporated into the cyan repo. someone should do the same with the SGS2!!

and regarding the heat, my nexus one gets extremely hot that it can sometimes barely be touched when its charging. it definitely has heat issues during charging. but not when charging thru USB, because current is capped at 480 mA there. similarly the SGS2 with a lower charge currnt likely doesnt get as hot. but i bet it would if the charge current were raised.
[Galaxy S II General] LightspeedGalaxy:
Sure, most likely because it is cheaper. Of course it is only a few cents, but on a large number of devices this makes a reasonable difference. Obviously Samsung is very frugal with the accessories of the Galaxy S2, it´s not just the poor rated power-supply, also the very cheap headphones, not even including a decent remote-control, and nothing else.

Are you sure you just changed the maximum charging-current? Maybe the whole charging-controlling is dependent on this, and raising the value can have unpleasant side-effects.

Li-Ion-cells can be charged with quite high current until it reaches the saturation-stage, which is at about 70-85% of its capacity.

In this stage charging has an efficiency of 95-99% (more on the upper side with a new cell, getting lower when the cell reaches the end of its life-cycle)

So even when we assume the worst case, charging with 1A will generate a maximum of 0,25W of heat, and this over a relatively large space. In reality we are more likely close to the upper-end of the efficiency-scale, because the cell is still knew, and the efficiency-data usually stands for a full charge, and it is considerable lower in the saturation-stage, therefore it must be higher in the "regular" charging-stage.

In the saturation-stage, the charging-current must be reduced to prevent the cell-voltage from going too high. If the current is not reduced enough, the cell-voltage will exceed 4,3V and it will generate quite a bit of heat.

Both is not good for the life of the Li-Ion-cell.

Perhaps simply raising the charging-current in the kernel confuses the whole charging-characteristics and therefore generates much more heat.

A Li-Ion-cell can get warm during charging, but it definitely shouldn´t get too hot to be touched. If this is the case there is something wrong with the charging-controller and it will decrease battery-life significantly.

This is still no reason to limit the current for the power-supply that much. The 700mA are quite decent, if they can be used for charging alone, not the fastest on the market, but enough to reach saturation-stage in about 90min. For a full charge it doesn´t make a difference anyway, you will always need 3-4h for a Li-Ion-cell. The faster you charge it until the saturation-stage, the longer the saturation-stage will last and vice versa. In the end you will always need 3-4h.

A higher charging-current will only have benefits if you want to charge at a low battery-level.

The weak power-supply becomes a problem if you want to use the phone while charging. In this case the phone could burn most of the energy and doesn´t leave much to charge the battery. If you had a stronger power-supply it wouldn´t be a problem still limiting the charging-current to 650mA and use the rest to power the phone.

Besides Samsung already implemented temperature-monitoring (I was glad enough to get a message like: too hot to charge the battery, when I wanted to charge it in a hot car) so there is no reason not allowing a higher charging-current when the temperature is low and limit it, if the temperature gets too high.

I am looking for an APP simular like QuickGPS (that works under WinMob). It is downloading some GPS satellite date and speeds up the fix.

[HTC ChaCha] ravilee:
Hi guys,

I own SE Xperia X10i about 10 months that it's just a pain in the ass. It sometimes performs very bad such as no response, laggy and muted by itself during in the call especially when I got the important calls.

I'm really sick of it and plan to move to HTC Chacha. My questions are;

1. In terms of specs, a friend of mine told me that Chacha holds a slower CPU than X10i. is it correct?

2. The overall performance should be faster and more response than X10i?

3. Is it worth to move on to Chacha?

Many thanks,

Lee
[HTC ChaCha] johnnydeathmatch:
The Chacha is much, much faster than the X10i. It's not even close. I don't know what the speed of the CPU in the X10i is, however, CPU speed is just one spec to consider, and not all that important in the grand scheme of things. CPU architecture has a lot to do with it. Think of it like two cars, one has a bigger engine. The one with the bigger engine might not be faster, because the smaller engine might have a turbo, better technology (fuel injection, etc) that gives it more horse power than the bigger engine. So it's important to recognize that the CPU in the Chacha is probably twice as powerful as the one in the X10i (at least).

Also, the Chacha runs Gingerbread which is nice and speedy. The Chacha seems to run quite well so far (had it about a day). I would recommend that you get a large, fast SD card to go with it, however, because you'll need to move apps to the SD card, as there is barely any room for them on the phone's internal storage. I'd say minimum of 4GB, recommend 8GB+. Minimum of a Class 6, recommend a Class 10.

I would definitely recommend the Chacha over the X10i, no doubt in my mind. The keyboard is fantastic, the phone is nice and quick, the hardware feels absolutely great (HTC build quality shows), the features are top-notch, you have access to a front facing camera, and the latest version of Android!

Best of luck!
[HTC ChaCha] x10addict:
Coming from another person who has moved from the x10 to the ChaCha, I can indeed confirm that the Cha Cha is a superior phone. It doesn't have the same technical specifications that the x10 has, but it does feel much, much more polished. The real selling point is the excellent keyboard, it's possibly the best full keyboard I have used on any small mobile device, ever. Also, for the first time in my life, I am finding myself using the ChaCha before my laptop to check forums and write e-mail's. This is genuinely the most excited I have been about a phone for a long time (considering that my last two phones were a SE x10 and a Nokia 5800).
[HTC ChaCha] cocaice2009:
I would say they are different type, chacha is a great phone for those who need an android phone with portrait QWERTY keyboard, or bb fans feeling bored with rim OS
[Hero, G2 Touch Q&A, Help & Troubleshooting] Anglooo:
I have been trawling around the internet, and this is turning into the most frustrating thing i have ever tried to do!

I will start from the beginning;

I was given a GSM Hero, locked to the 3UK network from a friend, with 2.1 update 1.. Im assuming this is the OTA update.

I looked into rooting and installing custom roms, i checked out a few guides and managed to use universal androot to initially root the device, But when i tried to install Amon Ra via terminal, i received the error Flash_image not found.

I then became very frustrated and decided to leave it for a while, but a few days ago i decided to persevere and try again! I read through more guides, including the guide on here, and got to know a bit about ADB and the use of RUU.

I tried the fixes noted in this thread;

http://xdaforums.com/showthread.php?t=645253

But they did not work, so i did a bit more digging and found that my firmware might need to be downgraded. So i downloaded the RUU thinking my problems had been solved!

Wrong!

everytime i run the RUU my phone disconnects and i get error 170. I have searched relentlessly for a fix but have so far found none that work!

i have also tried pushing a flash_image file onto the device, as i have come to the conclusion that it is missing from /system/bin/ but all the time i receive the error "Permission Denied" or something along those lines.

Thank you for your patience in reading this post, any help would be greatly appreciated! if there is anything else i can try or if i am being a complete noob if you could please let me know!

Cheers
