Physisc lol seems like you cut. Physics class, haven't you heard about rapid chargers?

I just called Samsung they told me even if I buy fast charger it won't work because the software design to regulate the amount of current when charging is set to a certain amp to not damage the battery,

So it is not physics it is just common sense because they told me that it is software. And the software has nothing to do with your 1750mah and your physics knowledge dreams of yours. And stop reminding me of physics I hate that class is too boring for me so I just sleep on my physics class.

Off course my grammar sucks because I only have been here in the US in a year, and I am lucky enough to live here in santa clarita where almost all American do not care about grammars, they are so educated enough to understand people who don't grew here in the US, and they don't use the word troll, I love living with white people. And hate talking to people tell other they are troll and he's not.

By the way try to go to Taiwan let us see how your grammar is in 1 year and 2 months then ask yourself if you are a troll or shrek
[Samsung Infuse 4G] halo0:
LMAO at this thread.

Butt seriously, this guy has a perfectly valid point. The Infuse charges MUCH more slowly than any previous android phone I've had. It's not even close, and it can't all be explained by a bigger battery. The battery in my Droid X was very close to the number of mAH of the Infuse, yet it would charge 3 to 4 times faster.

Does anyone know the maximum amount of current the Infuse is set up to use when charging? That way at least we'd know if it's pointless to get a new charger beyond a certain number of amps.
[Samsung Infuse 4G] netnerd:
If you use a OC kernel, you can set it at 100mzh max speed while charging. Not sure if this will charge faster.

[Samsung Infuse 4G] Entropy512:
According to comments in the kernel code, 600 mA. Unfortunately without the MAX8998 datasheet, I only have comments to go by. Unlike most of Maxim's products, the 8998's datasheet does not appear to be public. That's battery input current, then there's the current needed to just keep the phone running which is ???

It's possible to increase the current, I'm running a test kernel that does it. However before unleashing it on the public I need to do some testing, such as:

1) Figure out whether it gracefully handles input "voltage droop" from weaker chargers such as the AT&T car charger and many other car chargers out there. All of my new 1A chargers are actually not 1A chargers, good thing they were just over a buck apiece. (The MC34063A used in them can't reliably output 1A at 5v when off of a 12v supply.)

2) If it doesn't, if there is a way to make it do so.

3) What sort of battery overtemperature protections there are, if any. If there aren't, the current needs to stay where it is. :(
[Samsung Infuse 4G] MikeyMike01:
Hopefully this can be tweaked in the kernel... My 2100 mAh car charger could charge my Captivate 20% in a 15 minute car ride. The Infuse? Not so much...

I'll take a look at that at some point. Unfortunately he includes source in a tar file, not on github, so I can't just browse to it from wherever. ;)

As I mentioned above, it IS possible to increase the charge current in our devices by setting the MAX8998 PMIC's current limit differently, and I do have a kernel with the change integrated running on my device, but before publishing a kernel for public use I want to spend some time investigating possible negative side effects.
[Samsung Infuse 4G] nstong:
I personally couldn't care less. I easily make it to an overnight charge and then it can take as long as it wants (I'm on my third day of uncharged use right now). I'd rather the battery charge slowly and preserve it peak charging capacity (or as close to it as possible).
[Samsung Infuse 4G] Entropy512:
I think that *most likely*, other than the fact that weak-ass USB chargers abound and that could cause issues with higher charge current settings, it is safe to bump up our charge current 20%, since our battery capacity is 20% higher.

i.e. charge current up by 20% (which is what my current kernel tweak does) compared to other phones keeps our charge rate in terms of C the same as other phones.

I won't be porting any of the other charge tweaks from http://xdaforums.com/showthread.php?t=996631 to our kernels myself - in fact if anything to keep the battery from getting abused, I might pair the increased charge current with a more conservative topoff/charge termination threshold.

One thing that's interesting is our kernel seems to claim some sort of "step charging" code, however it seems to always go to max charge rate even when the battery is in the 90s. I still need to make sense of the stepcharging routine - it looks like it would just cycle between 4 different current settings constantly, but in reality it goes right to the max in all situations except for when the battery is in constant-voltage charging (near charge termination).
[Samsung Infuse 4G] halo0:
Yeah that's great for you, but for those of us whose phones die in 12-15 hours, not so much. In addition, the fact that the battery discharges while being charged in the car and running nav is kind of ridiculous.
[Samsung Infuse 4G] tjy8tim:
Lol, forget physics? Physics is the only reason with there is a frigging device in your hand making calls and running god-knows-what-apps. And it is the only reason WHY they won't allow it to charge fast. It is because of PHYSICS that your battery gets hot when charged too fast. So yes IT IS physics why Samsung WON'T allow you to CHARGE at a FASTER rate.

I apologize on behalf of rest of Taiwan. There are only few like him that is this rude and uneducated. And spirikitik, go back to Taiwan please, you obviously are not well educated enough to be in the states.
[Samsung Infuse 4G] DarkDvr:
Faster charging, in most situations, leads to a decrease in overall battery life.

Check the thread in my sig.

Slow charge is good.
[Samsung Infuse 4G] Entropy512:
I read the thread in your sig. In that case, faster charging, in situations of TOTALLY SCREWED UP CHARGING ALGORITHMS, leads to a massive decrease in battery lifetime.

Any Li-Ion charger that puts out more than 4.2 volts once in CV topoff is BAD. That thread is showing a chart with voltages well over 4.2V.

Also, another error is in EDGE vs 3G - While 3G may be more efficient in terms of power per bit transferred, overall, especially when in standby, it is less efficient. This is primarily due to the fact that UMTS requires a highly linear (inefficient) transmit power amp while old-school GSM/EDGE does not require any power amp linearity at all. Historically, throughout the entire history of UMTS, it has ALWAYS consumed significantly more power than GSM/EDGE. This is, in fact, why the original iPhone was EDGE-only in an era when nearly every other handset was 3G.

CV charging above 4.2V simply isn't on the table in any mods I'm ever going to do, and is not something our phones ever do. Our phones actually stop a little before 4.2V. However, we have PLENTY of safety margin in terms of bumping up our CC current limit. Li-Ion batteries can easily take 1C charge current when below the 4.2V CV limit, we're well below 0.5C.

As to discharging during nav - not sure if that's in any way relevant to the MAX8998 battery current limit or not. The simple fact there is that there are a LOT of ****ty MicroUSB car chargers out there.

1) AT&T charger is at most 500 mA is my guess.

2) Wal-Mart Just Wireless charger is slightly more but not much

3) The Monoprice "1A" car chargers are not. They limit switch peak current to around 800 mA, and while average input current to a switcher is lower than output current, peak switch current must be higher than average output current.

Gonna try to find a 2A charger tonight and see how that behaves.

However, it is possible the MAX8998 battery charge current limit is inclusive of device usage (CPU, screen, etc) and not exclusive. Too early to tell so far.
[Samsung Infuse 4G] halo0:
I picked up a moto 950mA charger from amazon. I don't think the battery monitor widget is accurate because it says it puts out 1100, but interestingly it says the same about my moto USB wall wart, which is also rated at 950, so I tend to believe they are putting out close to equal current.
[Samsung Infuse 4G] MikeyMike01:

You're arguing with the facts from Android Developers and electrical engineers.

Or, re-read the post and see where you misunderstood.
[Samsung Infuse 4G] DarkDvr:
Well, that's defective units/batteries/chargers.

We all know that ROMs get simply cloned on the factories, so software differences are highly unlikely (with exception of software updates at the factory, but that rarely happens).

I don't see how this can be safely and reliably fixed with ROM/kernel update.

[Samsung Infuse 4G] Entropy512:
I'm not entirely sure (will know for sure after a longer drive tomorrow), but using the Griffin 2.1 amp charger for the iPad, I think my battery stayed even for a short drive, may have even charged. Not sure yet...

It did better with a modified Monoprice charger than an unmodded one, but it wasn't good enough. The iPad car charger may be what is needed to do the trick, or at least a TRUE 1A charger. In the case of the Monoprice charger, I changed the resistor that sets the peak switch current. (Well, actually, I soldered one resistor cannibalized from another Monoprice charger in parallel...) Half the resistor value = double the current. As stock, it was only good for 600 mA...
[Samsung Infuse 4G] halo0:
In one test with my Moto 950mA charger while on nav, I witnessed the % drop about 3 points, then it stabilized and actually rose a point, but then sadly, started dropping steadily again. I believe my phone was in the 70-80% range somewhere when that happened.
[Samsung Infuse 4G] Entropy512:
I think to really investigate, I'm going to need a little breakout cable so I can monitor the USB voltage under heavy load.

Or maybe we have an ADC in the phone already looking at that, time to look around in the kernel...

Edit: Doesn't seem to be an ADC for the USB voltage, at least not any easy to find one...
[Samsung Infuse 4G] Entropy512:
Here's what I've discovered so far:

There seems to be no way to do automatic "brownout detection" of VDCin of our phones. Our PMIC only has a "voltage present/not present" flag, and it seems to report "present" when the DC input is "browned out" to the point where charging can't be properly performed. Of course, I'm still just suspecting brownouts until I can build a breakout cable that lets me connect my scope or voltmeter to the charger.

Stock charge current is 600 mA. For whatever reason, the value CurrentWidget pulls is 1.83 times the actual current. You need to set CurrentWidget to divide the value by 1.83 to get proper readings.

Available higher charge currents are 700 mA and 800 mA - no higher. I've been running a kernel with charge current set to 700 since the middle of last week, it seems to be going well except I think it's even more sensitive to weak chargers.

I'm thinking, once I've done more brownout research, of creating a kernel that chooses 800 mA when the battery is below 50-60%, 700 when below 80 or so, and then 600 past that.

It may actually be desirable to DROP charge current when under heavy load (Navigation) - this prevents weak chargers from browning out, intentionally routing power to the CPU/screen/GPS rather than making them fight with the charger for external power.
[Samsung Infuse 4G] halo0:
Nice. Good to hear you are making progress. Allow me to volunteer my services for testing when you see fit.

I've been using the Battery Monitor widget which is off by the exact same factor. I like that it will simultaneously display the batt %, current, and temperature or other selectable values, but it has no way to modify the current display like CurrentWidget does.
[Samsung Infuse 4G] Entropy512:
I can probably fix it at the source (kernel) given some time. Not tonight, that's for sure.
[Samsung Infuse 4G] MikeyMike01:
8 minute car ride, same setup, charger, cable and car.

In the 8 minutes (with the screen completely off the whole way) it charged a pathetic 1%.

At that rate it would have taken twelve hours to go back to full from the 10% I started with.

This is a definitely a problem.

[Samsung Infuse 4G] Entropy512:
Dock or not? 90% of the 2.1 amp chargers out there are for iDevices and will cause our devices to go into USB charging mode if not going through the dock. I know that's the case with my Scosche reVIVE II and the Griffin iPad charger.

Also, an 8-minute test is going to be prone to some rounding errors.
[Samsung Infuse 4G] MikeyMike01:
This is the charger:

http://www.rdi.us/USBCC.pdf

Someone PM'd me last year and offered to send one for free. So I've been using it ever since.
[Samsung Infuse 4G] Entropy512:
Since it's for iPad, their claims of it appearing as "Charging (AC)" are not true, unless you use the special charge-only cable they sell. (Which shorts D+ and D- to each other instead of passing through the iCharging resistors inside the charger.)

I'm running a test with my "cripplecharging" kernel that limits charge current to 80 mA - if battery drops, then it's a smoking gun that says the phone's power is taken from the charge current limit.

Edit: So far, not looking good...

Edit 2: At this point I'm going to crank the charge current up to 800 mA, and send a pull request to bedwa after I've tried running Navigation tomorrow. Worst case I might revert some of the changes once I have a chance to investigate with an ammeter...
[Samsung Infuse 4G] jimmie48jj:
have you had any progress?
[Samsung Infuse 4G] Entropy512:
After doing some more analysis I was uncomfortable about releasing those hacks against the Froyo kernel.

I've got some stuff I'm testing against the GB kernel that's a bit safer - it only cranks the current at lower states of charge, and drops it as the battery gets fuller. It will crank it back up if the battery voltage drops, so with Navigation running and the CPU allowed to run at full clock, battery will probably bounce between 4.1v and 4.15 volts, or maybe 4.05 and 4.1. I'm still tuning the transition voltages.

Is there a way to download the update and then puton micro sd card to update? I hadto do this with my Transformer.
[HTC Inspire 4G] Scott_S:
Are you talking about the OTA "4G-enabling" update?

I believe that's how it's done anyway. I think it saves it to your SD card, but I could be wrong, as I haven't actually done it via the "official" way being rooted, and all.

If that's what your talking about, that is... Please be as specific as you can, its easier for people to help when they know exactly what you are trying to do.
[HTC Inspire 4G] Carlrobling:
Yes it saves and installs from the sd card automatically. Im not sure that you can stop the update once its downloaded. As I did the update it automatically did everything.
[HTC Inspire 4G] BlackKnight:
The Transformer had the same update OTA and I was able to get the file and update. I just didn't know if someone had the link for the update file I needed.
[HTC Inspire 4G] Carlrobling:
I would google or search the forums for the update and see if you could find it. If you can find it then you should be able to flash it. But it will be an unrooted rom. So you will loose root access if you have it (not permanently just the rom doesn't have root the phone still does).

I found that the phone sounds crappy a lot of the time. The volume control range is too narrow, so the volume is either too loud at the lowest setting or too quiet on the highest.

I talked to HTC about the sound quality. They told me it was a software problem and would be fixed (Sure it will). They said to close the kickstand to make the external speaker sound better. Well if you can't hear it I suppose it sounds better. They said to turn the volume down so the ear piece sounds better. The phone also has a bad headphone amplifier. It distorts bad if you add a little base. This is my first HTC phone and it will probably be my last.
