[Vibrant Q&A, Help & Troubleshooting] ozmulti:
There has been no leak so far. I was wondering. Will it mean anything for us Vibrant users. I ask because i randomly read somewhere that the Nexus S was more like the vibrant than the I9000. It could be complete BS, but i was just curious. Wanted to ask
[Vibrant Q&A, Help & Troubleshooting] brian_v3ntura:
well the nexus s is closer to a vibrant than an i9000,but the only differences between the vibrant and i9000 are kinda miniscule i.e. supported frequencies,button layout,kernels and modems.

my friend is getting the nexus s on launch day(im going to be with him) and i will try to get a system dump out,but im pretty sure someone wouldve already beat me to it...
[Vibrant Q&A, Help & Troubleshooting] SiL3nTKiLL:
yeah hopefully a dump will be available soon....just give it time :)
[Vibrant Q&A, Help & Troubleshooting] ozmulti:
You sir, are awesome for giving me hope. I thank you for this gesture :D

Please upload the rom dump anyway. You may be the only one. Who knows :P

I have the seidio 3500 mah and love, especially after I found out how to manage it properly. Couple tricks with these larger batteries are as follows. This should work with all larger batteries.

1. When the charging light turns green, the battery is only at 1500. Keep on charge for about 3 hours longer or more to get full charges.

2. Wipe battery stats. Recovery, advanced, wipe battery stats. When you hit go, screen will go black for about 30 seconds. It's o.k. it's doing the wipe.

3.Condition the battery. Charge all the way, let run down completely till phone dies. Then charge all the way again. Do this bout 3 times. Should condition about 0nce a month to prolong battery life.

Follow these steps and you will love your big battery. I love mine. My Seidio runs bout a day and a half and I am constantly doing stuff with the phone. ENJOY!!!!
[EVO 4G General] DayoDee:
Ok are you using juice defender for it or any application that save battery life
[EVO 4G General] squick:
Nope, I only use task killers that can auto kill when screen turns off. Also, Itry to leave GPS turned off unless I need to turn it on. I just do as I posted origanally and it works great. I do keep my origal batt and back door available so when the batt gets low I can just run it completely dead. Oh yeah, I also have a spare batt charger the just charges the batt by itself.
[EVO 4G General] kse91holydiver:
Don't do it!!!! Task killers are horrible for any phones running FroYo.
[EVO 4G General] squick:
How come? It has never seemed to effect it.
[EVO 4G General] phatmanxxl:
Some apps hang so it helps to use a task killer, I exclude the apps that usually start in their own. I also noticed after I close everything after a reboot, the phone runs much smoother with just the necessary apps running.
[EVO 4G General] nabbed:
That makes no sense. When the light is green, the battery is at 4.15-4.2 V, and it's no longer charged at this point.
[EVO 4G General] DirtyShroomz:
Task killer should only be used if an app hangs, not set to automatic kill, android does this on it's own. GPS only turns on when an app needs it so turning it off does nothing. I get a full day and a half on a standard battery with Wifi on, GPS on and juice defender set to every 15 minutes which I'm now turning off due to facebook app and push notifications.
[EVO 4G General] jpatterson350:
So you can leave GPS on and its not killing the bat unless your running a gps intensive app? :eek: I had no idea....

Thanks

[EVO 4G General] squick:
The voltage isn't the the same as amps. When the batt is at 1500 it still has the proper voltage to run the phone but the cells are not full. The EVO is set to turn the light green when the batt is at 1500. I found this to be true cause when I first got the batt I would charge till it turned green then off I went. I wasn't getting any better batt life until I found info on how to properly charge these batts. Now I get bout a day and a half.
[EVO 4G General] sweteg:
Squick is right. Let it charge for another few hours after it goes green for the extended battery from Seidio. If you unplug it right after it hits 100, it'll drop to 75 pretty quick. So let it keep charging.
[EVO 4G General] nabbed:
The charging circuit has no way of the determining the charge capacity. The only property that can be measured is the voltage, and consequently the rate at which voltage is changing and the current during charging.

If the charging circuit relied on capacity, you'd never be able to charge past 1500mah.

http://en.wikipedia.org/wiki/Lithium-ion_polymer_battery#Charging
[EVO 4G General] squick:
After all that I have read and personally tested, the battery is not fully charged when the light turns green. I have taken the phone off charge once the light turned green and the battery lasted no longer than a 1500. I found numerous threads that stated that the evo goes green once the battery reaches the 1500 point and that you need to charge well past the green full light. Once I started letting it charge at least 3 hours over, I get awesome battery life. If there is another explaination for this I would love to know!
[EVO 4G General] nabbed:
Try this:

1) Charge the phone till the light goes green.

2) Power off the phone completely (shut down).

3) Charge more with the phone being off until the light goes green again.

I'm guessing the extended battery like 3500mAh should be nearly fully charged at this point, and it shouldn't take more than 30-45 minutes for the second charge, as opposed to 3 hours.

The reason for this behavior, and I'm guesstimating here, is that HTC optimizes charging in the kernel to never exceed a certain limit, which is very close to 90-95% charge. A double capacity battery, having a different charging rate and the limit current, should be at 80-90% - double the difference - when charged with the phone on. Eliminating this optimization from HTC by charging with the phone off should, in principle, allow faster charging to nearly 100%.
[EVO 4G General] PGRtoo:
Nonsense! The Evo uses a LiPo battery and there is no beneficial reason whatsoever to running the battery down. In fact, running the battery down unnecessarily will reduce the cycle life and the calendar life. In the simplest of terms, the LiPo cell chemistry is only capable of so many charge-discharge cycles before it loses significant ability to store energy and unnecessary cycles just use 'em up unnecessarily.

In fact, a bunch of

partial

charge-discharge cycles are a lot easier on LiPo cells than a few

full

charge-discharge cycles. In other words, your battery will remain healthy a lot longer if you charge it whenever you can instead of waiting until you have to all the time.

[EVO 4G General] nabbed:
Agreed. The only reason to discharge the battery completely might be to reset the battery calibration data and to recalibrate. But I really don't know if that even works.
[EVO 4G General] squick:
Just saw the posts. I did not know that, but the rest still seems to work. If I charge the vary well past the green light, I get almost 2 days of use out of it.
[EVO 4G General] ms79723:
I need testers for my battery fix that in theory, should charge all batteries (stock and extended) to maximum capacity. So far I tested it with a stock battery and it only lost 4% in an hour after being on the charger for 2 hours. Im testing my extended battery right now(it's only 1800mah).

here's the thread: http://xdaforums.com/showthread.php?t=876590
[EVO 4G General] :
Don't be stupid and fall for this trick. It's only prank in case noobs don't know. A day and a half is normal for 3500MAH battery with full use ( abuse the hell out of it ).
[EVO 4G General] ceg1792:
I think nabbed has got it, your battery loops once it gets to the max the battery can hold. Its megahertz, not amps or volts.. Your phone tries maintaining 100% by letting itself lose power and have to charge back up. Like I said, its a loop pattern.
[EVO 4G General] nuggyunlimited:
I want to by a 3500 battery but I don't want to give up my seidio rugged + holster maybe if I could sell it to someone I know with a evo I'll buy one and did seidio make a car mount that can fit the extended rugged yet? Does the rugged extended some with a holster? Lol my phone is going to feel like a glock
[EVO 4G General] mikeb4g:
How do you reset the stats?

I need to buy a extended battery any good prices out there
[EVO 4G General] seanjohnevo:
Try Amazon I was told they have great prices
[EVO 4G General] noregretzzzz:
Hey guys, i just got my first extended battery and had aquestion, or maybe someone can point me in the right direction. I wiped battery stats just in case before putting it in, turned on the phone and now the phone does not recognize either pc or ac charger connection. My circle battery icon w/percentage shows a red exclamation point now. Was there anything else i shouldve done? Or possibly a fix for this?
[EVO 4G General] BrianDigital:
If you guys are rooted there is kernel that was developed to just charge up extended batteries and well charges stock batteries fully\

http://xdaforums.com/showthread.php?t=876590

I got a cheap battery off ebay awhile ago and with this kernel it actually is pretty badass
[EVO 4G General] noregretzzzz:
Yea, ive been running that kernel for the past week even with the stock battery, but now putting in,the extended battery, im exoeriencing those issues with all kernels, tried sbc,net,and king. i dont think its kernel related

Swyped from my fresh evo
[EVO 4G General] dondochaka:
In my experience, when the light turns green, the 100%-90%-100%-90%-etc looping starts (even when using the 3500). If that's true and if you're right, then the battery would never exceed 1500 mAh.
[EVO 4G General] squick:
Give it a try. Try takeing the phone off charge once the light turns green and see what kind of life you get. Then next time try leaving it for several hours after and see what you get. I'm just repeating what I've read in several threads. I have tested this with results to backup my postings.
[EVO 4G General] bones841:
How do you wipe batt stats?
[EVO 4G General] squick:
Easy. Just go to recovery and it's in there. Just look for it. Honestly I forget where it's at, lol. When you press power to confirm the wipe, the screen may turn black with one line of some words. Don't worry, just wait. It takes a few seconds
[EVO 4G General] AFH:
Anyone notice the extended battery affecting reception any? I work in a marginal reception area, and when I replaced my slimmer standard battery the reception seemed to drop; I even experimented and swapped the battery out a few times - seems to be the bulk/thickness of the battery.
[EVO 4G General] andyk11:
I also have the seidio 3500 very shortly after the first day the EVO went on sale. The original 1500 ma battery was terible as we all read and heard the stories. My phone would last maybe 5-6 hours and need a charge. I also as soon as I got the EVO home rooted it. I have since tried the gambit of roms available. In the process I have learned and played with different functions turning on and off. I am a business man and rely on my internet phone ALOT. On average I get as most people here do a day and half of heavy use. I also get up to 3 days if I take a weekend off and not really use my phone alot. What I have done is study my phones battery use and found I can in fact delete/uninstall useless apps and funcation I don't plan on using. a short example is sprint tv, sprint football and nascar which I found better more usefully apps for. I do use task managers to disable app use I don't need running at the time. There are also many sensors in this phone running all the time that don't need to. most apps and sensors use from 5-50ma even if there not running. if you add all these small amounts of ma (miliamps) up, they eventually add up to a good battery drain. Some coments here where right on as far as charging longer than needed after the green charge light comes on as I noticed my 3500ma battery does need an extra 3 hours for the ma count to reach it's peak.
[EVO 4G General] SayWhat10:
charging past the green wont do much

phone stops charging when its green and does NOT trickle charge

it will recharge at 90% but bug in HTC which never really charges extended batteries. If you want your 3500 battery to actually charge to full and STAY full after you disconnect (and not have to do the silly charge...unplug...charge...unplug crap) then make sure you use that new kernel that I believe someone posted above. You will not get any full charge unless you use that kernal which specifically addressed the charge issue
[EVO 4G General] nuggyunlimited:
I was trying to figure out if the seidio rugged extended would fit a knock off 3500mah battery and back or would I have to get a seidio back to cover the knockoff battery to fit the case. Does anyone know?
[EVO 4G General] CCallahan:
I have the Seido 3500 extended and this is what Seido told me to do to get optimum life from the battery:

Here is what we recommend if your having problem charging the battery. Please try to fully drain the battery until the phone completely shuts off automatically and then charge with the OEM AC charger that came with your device. Repeat this process 3 consecutive times. This will recondition and also recycle battery usage for best performance.

Thank you,

Seidoonline Technical Support

I am not sure how discharging a Li-ion battery all the way is helping but seems to be what all manufacturers are recommending.
[EVO 4G General] z28marols1:
The charging sysem has nothing to do with capacity. Batteries are not tanks your are filling up. The charging system uses the voltage the batteries are putting out to determine how full they are. The more energy the battery has stored in relation to its capacity the higher the voltage it will put out. Therefor the charging system knows when the battery is at full capacity regardless of the size of the battery. As the battery gets closer and closer to the max amount of energy it can safely store the charging system slows the rate of charge to a trickle charge and will say its fully charged when that level of charge gets to a certain point. You will notice a little bit of a fuller battery if you leave it on the charger for maybe another 30 minutes because it is still trickle charging. After that point it stops charging and starts discharging to keep from overcharging the battery.

While bump charging and charging the battery way before its completely empty will not hurt the battery and will even help the battery life compared to letting the battery get all the way down before charging, continuously charging the battery when its almost at full capacity already will shorten the life of the battery. Li-ion and LiPo batteries do not like to be fully charged and constantly forcing a charge on a battery of this type that is already at full charge will shorten the number of cycles your battery can endure. The only thing worse then over charging one of these batteries is letting it drain to the point you have a dead cell that will no longer accept a charge. Your best bet for bump charging is to wait till the battery is down to about 40% and then bump it back up to 80%.

Also, do not store your batteries fully charged and do not expose your batteries to heat when unneccessary. There have been many tests that show these batteries lose charge cycles faster when stored at full charge and/or in hot environments. Keep them at room temperature or lower when possible and for storing them prefferably around 40% charge (why do you think the batteries come from the manufactures with around 30-50% charge on them?)
[EVO 4G General] z28marols1:
The best analogy for a battery I guess would be an air compressor. The compressor itself will pump air untill the tank reaches the predetermined pressure. It doesnt matter if you have a 5 gallon tank or a 50 gallon tank, the compressor head will continue untill that pressure is met.
[EVO 4G General] eye4ni:
You guys who claim that the evo stop charging when the light turns green obviously have not used the seidio 3500. This guy is not making it up, I've been using this battery for months and can attest that the battery keeps charging after the light turns green, plain and simple, it just does.

Most of the time I plug my phone in every night, and wake up to a fully charged battery. Once in a while I forget to plug it in and when I wake up in the morning I will plug it in, only to find the green light on after only an hour or two. If I unplug after only charging for this long, the battery will quickly drop to 70-80% after only 5 minutes. This happens EVERY TIME. It is not a fluke, the f'n battery needs to charge for an extra couple of hours to hold a full charge, so quit calling the guy a liar, he is right.

But on the task killers, I gotta disagree. They are unnecessary and counter-productive.
[EVO 4G General] z28marols1:
He's not a liar, it will continue to trickle charge for a SHORT period of time, not 3 hours.
[EVO 4G General] mercuryhayes:
too many different opinions

does that mean there's different ways?, or does it mean no one really knows the truth?
[EVO 4G General] z28marols1:
lol there are a lot of opinions out there. A simple google search well teach you a lot of what there is to know about these batteries and their charging systems. In my research I have found that the green light will come on when the battery is very close to max and the resulting time spent charging vs actual charge given to the battery is inefficient. This happens because as the battery gets to full the charging current gradually goes to 0. What this means is that up to about 80% the battery is charging rather quickly. Past 80% the charge get relatively slow. Also, once the battery truely reaches 100% the charging system will allow the battery to discharge (I have read that it will let it get down to 90%) and then recharge it back to 100% to keep from damaging the cells with a constant charge.

To sum it up, you will realize a longer battery life if you leave it plugged in after the light turns green. 3 hours sounds excessive to me and im sure the battery has already begun the discharge/charge cycles by then. My experience would say that 30 minutes to maybe an hour on the extended batteries is sufficient to let the cells reach maximum capacity.

As a side note, if you find that you don't use the full capacity on a regular basis you will notice longer cell life (overall life, not capacity for the day) if you dont push the battery to its maximum or minimum charge levels.

Hope that helps to clear things up!

I know sources helps to justify opinions, but I am not going to take the time to find the sites I used to learn this information. All I did, however, was google info about these batteries and used reputable websites (ie. battery manufacturers websites). Even wikipedia has some usefull info, as well.
[EVO 4G General] mercuryhayes:
youre right. I bought my 3500 extended last week...learned that you definitely have to leave it charged after the lights green to get full capacity.

after i immediately unpulgged it after the light turned green..it would drop to 77 after a few minutes and stay there for a while. now i leave it on for a good amount of time after and its about normal.

3 hrs is too much...id say an hour would suffice.

Hey guys just wanted to ask if it's possible to hack the display drivers of the defy to be able to register unlimited multi touch inputs...At the moment it's only capable of registering 2 fingers at the same time tested with a multitouchtester app. But for some games like zeonia it would be nice to have more than 2 finger tracking. Any one can point me to a good thread? thanx
[Defy General] pedrodh:
Try to edit build.prop. There you'll find an option called:

ro.product.max_num_touch=2

change to higher values. Although I doubt anything more than 5 is impossible for all current devices, hardware limitations that is.

where is the build.prop located?

[Defy General] cruuz:
thank you for your precious first post... it helped me a lot...

ok i just seted ro.product.max_num_touch to 3 but it didn't changed the fact of maximum 2 points at the same time. Maybe the restriction is deeper in the system or in the driver...
[Defy General] lolmensch:
it is the hardware
[Defy General] Perilla_:
Hardware? Impossible more than two touch points?
[Defy General] Le_Poilu:
I don't think it's hardware limitation. A capacitive touch screen is multitouch or not. I don't see how it can be only 2 point via hardware limitation.

My guess is that it's driver limitation, as often whis this stuff.
[Defy General] yyhoney:
well......i think it is software limitation.

i've known Apple has the licence that 3~5 point touch.

And In Korea, someone suceed in 5 point touch by editing driver in LG OptimusQ.

(but that device has snapdragon)

Now Tap Tap Revenge is out, any clues on more multitouch points? Can't play Tap Tap in Extreme mode with only 2 fingers! D:
[Defy General] rockx0:
I thought that when you upgrade to Froyo this problem would be resolved = /

is it really a hardware limitation?
[Defy General] zakoo2:
afaik it's not a hardware limitation, it is more about whether the kernel supports full multitouch or not. so maybe with froyo we'll get full mt (fingers crossed). btw, does the 2.1's kernel have full mt support at all?
[Defy General] :
It could be both hardware and software. There's an upper limit of both, and it's of the lowest denominator that dictates how many inputs are there.

There's a torn down here, see if you can make out what the actual parts are...

When I got the G2 brand new, I didn't notice any dust under the screen, but after around 2-3 weeks of light use in normal conditions (if slightly cold) I see dust under the top left of my screen.

It's definitely noticeable against a white background and now I'm thinking of trying to exchange it. I'd have to flash back to the stock ROM etc. and probably not have my phone for a couple weeks again.

Maybe I'll wait till christmas and go to the store and try to exchange it.
