Use Touch Pro without Battery in - Touch Pro CDMA

Hey,
So I used to have the Titan. Often I would take out the battery and just use the phone without it in *edited* while plugging into the wall, in order to save the battery for later....or to avoid the battery from over heating and shutting down services on the phone.
Pretty simple:
Is there anyway to program the phone to stay on with the battery out *edited* with the wall charger in? Seems like if on the Titan you could do it, here you should be able to as well?
Edited for xander

just because you were high and seeing stars doesnt mean you can operate a phone with no power unless you have a wall charger. although you failed to mention that so this thread should be kaput.

the above reply was almost as bad as the original thread post.

giggly
I definitely should have read over what I was about to post.
anyhow, any solutions?

Mine works just fine without the battery in if I plug it in......... no mod needed??

You do realize that once the battery is completely charged it is no longer charging. Just about EVERYTHING Li-Ion is "smart charged."
The batteries would burst into flames if continuously charged.
I have had a VERY low battery (5% or lower) and plugged into a 500ma power supply (typical USB charger, not HTC factory) and while really taxing the phone (streaming skyfire flash videos back when Hulu worked) and it would only charge the phone 10 percent in about 20 minutes. Sometimes it seemed it wasn't charging at all. The phone is really sucking some current, cellular radio downloading large amounts of data, processor is blazing running skyfire.
Now with the HTC factory charger being a 1000ma (1A) power supply it could obviously supply enough power for the TP at "full demand."
Goes back to the original question.
WHY?
It isn't serving any benefit. Li-Ion does not have a charge "memory" like old NiCd batteries or NiMh. Yes there are a certain amount of charges the battery can take but again, the phone is a smart charger. Once the battery is at full capacity (you want a charged battery right?) it no longer is charging. There is no battery degredation occuring.

to simply answer the op and not beat him to death with words, there is an easy answer to the question... no, there is no software to be able to do what you want for 2 reasons. one, there is extreamly low demand for the application. people here don't generally spend a week or 2 making a program to make one person happy. they'll do it for a hundred people though. two, i could be wrong about this reason but i don't believe that the hardware will allow it. it's designed to have the electricity run to the battery first, then the phone draws the energy from the battery for use. to my knowledge the phone doesn't have a way to be able to use the energy from the charging port directly. sorry champ, the only way that you are going to get this done is with an electrical engineering degree, soddering iron, and the circuit blueprints themselves.

to simply correct the poster aboive and still think about beating him to death...
yes it is possible, no you do not need extra software... and yes the hardware supports it... Im sorry I personally don't know how to do [email protected]: But if you post over @ PPCGeeks im sure they'll figure it out for ya.
I know it's possible for two reasons... If your phone is plugged Via USB in the bootloader, you may take the battery out. Also, on a ROM that I had installed previously my phone froze for about 2 mins and the battery was blazing so i took it out... To my surprise it was still on (i was tethering) and working perfectly! ZOMG...I love people who answer unknowingly...
For the person who said the smart remark about the lithium battery, im sure the OP knew that, but requires the phone to work with the battery off after he was done charging it... This would let him tether or do what it is that he needs endlessly without worrying about the battery overheating...
In other words, if you're not here to help, then sthu... Dont ***** about his question, dont insult him... Either help, or move on...

Uh, I tell you what there buddy. I'll take your post seriously when you can learn some grammar. For all I know I'm talking to a 12 year old know it all who ALSO doesn't know how to keep his mouth shut.
I WAS offering help, by telling him that there is NO POINT in removing the battery. I implied NO disrespect with my post.
If you are referring to problems with certain software causing the phone to overheat and restart/lock up... again that has NOTHING to do with the battery. For example WMWifiRouter, or streaming high kbps video.
The wifi/cellular radio/processor is what is generating the heat.
If you're not charging the battery (IE battery=100%) then there is NO HEAT GENERATED. The heat is not coming from the battery.

haha whatever...
what a poor redneck duck

Double Post...

Ok smartass.
Explain to me how tethering your phone with a charger plugged in and the battery already being charged causes the battery to heat up.
Think long and hard about your answer. Go ahead and post with your "mAd tyt3 h4x tyP1ng s|<Illz DAWG!"
I'm a ****ing electrical engineer, with a Masters. Take your poems and books and literature discussion groups and go **** yourself.
Only way that is going to happen is if the phone is consuming more current than the charger can provide.
IE: The phone is consuming 650ma, but a typical USB charger can only supply 500ma. In that case then the even simpler answer is NO you cannot use a charging adapter with no battery plugged in.
If you're a car guy here's an even better analogy.
Your car has an alternator (generates current) and a battery (stores current).
If your car's alternator is rated at 100A, then at a specified RPM your alternator generates 100 amps of current.
However, at idle your alternator may only be generating 40A.
If you're sitting at a traffic light and your headlights are on, heater blower fan is going, window wipers are on, heated seats are on... you're consuming more power than the alternator can provide. So the car is pulling current from the battery. The second you leave the traffic light and accelerate and your engine is spinning fast enough that the alternator can generate enough current to supply the demand and charge the battery.

Easy buddies!
We all are here to share knowledge we have to each other right?
Plz. don't let a small thing cause big problems!

as hippy-rific as navi_mappers statement is, i have to agree with him. people are getting a little too angry about this. it was a simple question. unfortunatly it has been answered in contradictory ways. one thing has remained true in most posts though: there is little reason to do what he was trying to do. i believe that he can take that and walk with it. there's no reason that we (as educated and intelligent people) need to resort to name calling and slander. i'd like to think that we are a little better than that. so shut up, stop *****ing and answer the mans question with intelligence damn it! i'd expect this kind of stupid crap over at crackberry.com, not here.

battery smells, but not very hot?

i have a stock HTC Tilt-2 and noticed that it always has a metalic smell coming from the battery connection inside the back cover...
it gets really, and i mean REALLY bad during heavy use, to where the smell comes through the case and actually is 'stuck' on your hand... lol
it seems to run fine, battery will last about 2days under normal use with out charging...
i do put it on the charger every night just to make sure i have a full batt for the day incase i need it...
cant really smell it with the case on, but once its off, theres no mistaking it...
could i have a faulty battery? or is this normal?
ive got about 85 hrs of talk time on it, not even counting all the internet and other misc time...
maybe i should just get a new battery?
trouble with lithium batteries are that manufacturers don't really now very well what's going on inside. for ref see the last news about how they just discovered new method of observing lithium bat chemical processes inside.
problem is something is getting stuck on electrodes, building up till it short-circuited them and may even explode. this issue is the reason they didn't put more power in market-lion batt. though they know how, people could get hurt.
This doesn't mean nowadays bats don't have this issue, it's just not as strong and double thermo sensor protections seems to be good enough with them.
If there is smell there would be escaping liquid as well, that can damage your circuits. if you think something is wrong with lithium batt, don't take a chance and change it.
Indeed, lithium batteries are weird. if it's smelling, get another one ASAP. It's not supposed to leak liquids or smells, and if it does you're probably bound to be one of those poor bastards linked to on the Internet where their battery burns their pants, chair, or whatever.

Rooted WiFi thethering while charging.

I had considered getting rid of my home internet to save money and use Root tether for internet.
A friend of mine had said you cannot charge and wifi tether. He said he wasn't sure, he said he thought because it will get too hot.
Out of curiosity I have been charging while tethering WiFi and it does not seem to be getting too hot at all. Just about as hot as it usually is while charging. In fact I am doing it right now.
I had read that there would be an issue with possibly lessening the battery life by letting it be plugged in once its fully charged and continuing to tether. That doesn't make too much sense to me since it starts running off the battery as soon as it is fully charged and then just keeps it topped off.
My question is this....
Is there any reason why it would be bad to charge and wifi tether at the same time?
I may be new to smartphones, but that don't make sense. If in doubt you can take the battery out after its charged.

the phone wont run with the battery out while plugged in. i dont personally own a tbolt yet, but every other phone ive touched doesnt work without the battery in.
All batteries eventually lose some charge no matter what, due laws of thermodynamics. Eventually some of the energy in the closed battery system wont be renewed by repeatably charging the battery. Having to charge it more frequently will obviously accelerate the process, but who knows how much. I am sure someone has done studies on it if you google.
The more pressing question is, why do you think it's more expensive to buy a 50 or so dollar battery every so often than pay 30-50 a month for internet if you think you can use it to replace your home connection? Assuming you arent going to need to buy a new one every month and I highly doubt you would.
Batteries also lose somewhere between 10-20% of their electric potential every year regardless of use just from something called "self discharge." Temperature extremes (high and low) can have short and long term effects on battery life as well since it slows or speeds up the reaction of the chemicals in the battery.
Regardless, you dont have to keep it constantly plugged in, you can charge it and then unplug it until it gets low.
As for excess heat, the heat wont be generated by the battery being charged so much as overuse of the antennas in the phone.
Yeah. I am thinking the same things. It doesn't make sense to me why you couldn't do it. I did it last night for hours..... No issues.
Sent from my ADR6400L using XDA Premium app
Pretty much what everyone else said. Keeping the phone continuously plugged in will definitely shorten the life-span of the battery.
That being said, it's worth paying $50 every 6 months to a year to just replace a battery than it is to pay it monthly for internet service.

Leaving Gtablet on

I use my Gtablet all day and I always shut it off and turn it back on ( boot it up) and ofcourse that takes 2 minutes or so.
Will it do any harm (or kill battery etc) if I leave the Gtablet on all the time like a pc ( maybe re-booting once a week or so) and just hit the power button to shut the screen off. Just dont want to kill my device by leaving it on all day and night. Just curious if anyone does this and if theres any harm to the device.
Thanks.
It will drain battery faster, so you will have to charge it more. That will probably reduce the life of the battery as well, since it will have more cycles.
I do the same as you, turn it on when I first use it and shut it down at night. No reason to drain a battery overnight, IMO.
Forgot to add that I leave it plugged in and charging all the time until I use . But yeah I guess turning it on at night and shutting off before bed is not a bad idea.
Thank you.
I've been confused by this situation, becuase when I first got mine, I made the opposite comment and was made too look like an idiot.
There was a post a while ago regarding how to get better battey life. People were complaining that their G-Tablet would lose too much battery life when left in sleep at night (not plugged in) I made the comment "Why not just turn it off?" and people responded with "Because it's a tablet."
Having NO IDEA what they meant, I asked what they were taloking about. Basically they explained to me that a tablet should be treated as a cellphone, not a computer. "You don't turn your phone off at night, do you?" was one question asked of me.
I'm still lost, becuase frankly, I think that they were just being stupid. The tablet IS more like a computer than a phone, as far as battery drain goes. I'd be in a world of trouble if my battery only had a 10 hour drain while in standby.
SO, I turn it off, and leave it plugged in at night. I use it all day, then plug it in (while on) in the evening so that I can access it if needed. Then, before bed, I turn it off, and just let it charge all night. occasionally, I will leave it plugged in an on at night. I figured that's what I do with my cell phone too, right?
Leave it on, all the time.
My wife and I both leave ours on, all the time (well she has too because it will not boot once turned off unless I nvflash it). There is no reason to turn it off unless you have to have longer than a day for battery life and are opposed to charging it every day.
I take it off the charger at 7:00am when I leave for work and then put it back on the charger later that night. Depending on how much I used it (were lots of apps updated, did I run another titanium backup, etc...) determines if I need to plug in earlier or not.
My wife leaves hers on the dock and takes it off to use, then places it back when done.
To help with battery life though you can set the screen timeout to a low time...so once you stop using it....the screen will timeout quickly and put the tablet to sleep.
Here is my very uninformed opinion on this debate.
The PC is designed for you to turn it off when you're not using it. The phone/tablet is designed to be on all the time and just be put to sleep when you're not using it.
The first sign of this is the OS itself. In windows and mac platform, once a program is running it will continue to run and run and run like that annoying rabbit until you stop it. And if you leave those programs running in the background they will do nothing but eat up your memory. What you then have to do every once in a while is to reboot.
In fact, back in the first gulf war there was an incident where a computer controlling the anti-missile defense system of a base was left on too long. They kept leaving it on because they were worried about incoming missiles. When the real missiles came flying, the system had already used up all its memory and made inaccurate calculations to counter. I think a few people died as a result. The incident could have been prevented if they had rebooted the computer. I remember reading about it back then.
Anyway, android is designed for your phone, which is meant to be on literally all the time. Especially with froyo and up, there are built-in systems to shut down running apps that aren't being used. Memory cycles also act differently so you don't run out of memory the way you do with PC.
Another thing is there is such a thing as turning it on and off too much. A significant determination of the lifetime of your electronic devices is how many times you turn it on and off. Not only that, The lifetime of your battery (how many cycles of charges you can have) also depends on the age more so than the actual number of times you recharge it.
You can very easily experiment with this by buying a brand new camera battery and just let it sit there. After a couple years, even though you've barely used it, you could only get less than an hour (sometimes even much less) even though when you bought it it's suppose to last your camera a whole 3 hours with a full charge.
That said, I'm running calkulin+clemsyn combo with cpu master setting the speed to 1.0 ghz most of the time. It's only when I want to impress people do I put it up to 1.5 ghz. I've tried both methods. For a couple weeks, I would turn it off every night and on every morning. Then for the next couple weeks I've been keeping it on all the time and only putting it to sleep while docked at night.
And I know this is only anecdotal evidence and is perhaps meaningless in science (I'm a researcher) but the gtab appears to be working a lot smoother and better when left on all the time.
Just my 2 cents.
It's a tablet, by design it suppose be turned on and be ready to use in no time at all when you fancy to dig up internet or watch movie, netflix etc.
The one way to achieve such readiness is to never shut it down. But from other hand, why waste energy when not in use.
So, here we go with "sleep" mode which is by the way implemented in Android 2.2 and 2.3 very poorly (in comparison with iOS). gTablet with Froyo, GB would typically loose 0.9-1.5% of charge per hour "sleeping" and then again there might be runaway apps which stuck in endless loop and will kill your battery in no time.
I've tried lot's of things and nothing can bring down discharge rate in "sleep" mode less then numbers above. So, I just keep my gtablet charging overnight.
Sometimes I just shut it down. Especially, when I found the way to speed-up cold start from 2 min. previously down to 40 sec.
Thanks all very informative and appreciate all the opinions.
I turn my gtab off at night but charge it only when necessary. I never use it while plugged in. I don't see the parallel between gtab & cell phone since I've not missed a call on gtab
My tablet is never turned off, unless the battery dies.
Part of the whole point of the tablet paradigm is the instant-on/instant-off concept. Remember, putting it to sleep uses very minimal amounts of power. Most functions go into standby, its a lot more than just "screen off". If I don't use the tablet much during the day, it can easily last until the next before having to charge again. Putting it into airplane mode and leaving it on all night will probably not consume that much more power than booting it up again in the morning (remember, when the CPU is being used it consumes more energy. Booting up is intense, sleeping is not).
Heck, I heard HP was considering leaving out the ability to power off their WebOS tablet (coming from the world of Palm, where many devices did not have the ability to shut down completely).
Stop comparing it to a computer- they aren't exactly phones, think of them as something more like a giant PDA. The same way you didn't have to shut down your old Palm Pilot throughout the day- imagine waiting for it to boot up each time you wanted to quickly check your calendar! The idea was to quickly turn on, do something and turn off. That's what a tablet is supposed to be.
Seems most here are bringing personal preference/philosophy into this. The question is what was best for the tablet. So, I looked it up...
The biggest factor is the battery, of course. gTabs have Li-ion polymer batteries. Here's a decent synopsis:
Li-ion and Li-ion polymer: Used on a lot of newer devices, has no "memory" effect, should be recharged as often as possible, actually likes to be charged and draining it regularly can cause the usage time to be shortened, can NEVER be overcharged so whenever you're near a charger put it on there. Besides those benefits a li-ion battery is lighter and smaller but the chemical can hold more charge than Ni-cad and Ni-mh.
So the one reply to your question said to error on the side of draining the li-ion batteries. This is incorrect information. You want to charge the battery before it gets below a 20% charge. Also batteries will not go bad from accidentally doing the incorrect charging procedure here and there but normally follow the correct procedure.

Yes, I remember 5-6 years ago, there was a whole movement about li-on and polymer batteries (which are VERY different, btw) being charged as often as possible.
My theory is that this was started by battery manufacturers, as every person I know who followed this philosophy needed to replace their batteries during the useful life of the product (be it cell phone, laptop, etc).
The general theory (and the one I have had success with), is to NOT plug it in unless you are ready to charge it 100%. How often you charge doesn't matter, however do not disconnect a battery if it is in the middle of being charged.
But aside from all this, I thought the question was how is the G-Tablet supposed to be used.
The answer is, like a tablet. Not like a computer. If the G-tablet can't be used the way a tablet is supposed to be used, its not a very good tablet then, is it?

Powering off? Should really have no effect on battery life in the long run. The cons are that you have to wait for it to boot back up again which takes substantial power and time.

Meanwhile, buchaneer.nl, part of the philosophy of the tablet concept is that it is supposed to be always on. Otherwise, if you intend to use it like a computer a netbook is an infinitely more functional tool for the same money. No hacking about to enable Skype, Netflix, Hulu, you get full office and a keyboard, etc. They are just different paradigms and designed for different uses.
A tablet is supposed to be casual use. Turn it on, turn off. Hold it. charge it when it beeps. Repeat.

The question was, is it better to turn it off, or does it do harm to leave it on all the time. The answer is it doesn't matter, so long as you perform proper charging of the battery.
As has been said, this is not like a computer, which has hard disks drives which wear out from spinning (and thus, reboots take a toll on the device). So rebooting does no harm, other than impatience for waiting.
And I guess as part of the over 30 crowd, I remember when booting a computer took FOREVER. So to me, booting the gTablet is nothing. I leave it on if I know I'll be using it in the near future, but otherwise, I turn it off.

Is it bad to completely drain the battery?

I've come across some people that say the GS2 battery should not be drained completely since for this type of battery it's not good.

Pants - is the only way to describe that post, false info.
It does no harm at all to fully discharge, more problems are caused by giving regular, short charges, than 1 long full charge so i wouldnt believe that.
He also says to charge it 8-10 hours, that total rubbish as well, these batteries dont need 8-10 hours to prime, on average 3-4 hours for a full charge is more than adequate.
I think few year back batteries were far inferior and did indeed need longer charging periods, but not any more, and if ya flash roms a lot and need to calibrate your battery after flashing to a new custom rom indeed part of the calibration process is completely running down the battery, my s2 is well over a year old and has been drained flat many a time and i still get 14 - 20 hours out of it on average, which is damn good for any smart phone these days, That post is on a HTC Thread by the way, Htc notoriously have batteries with a crappy life span, i had a wildfire s, used to get about 6 hours out of the battery.
I don't think that's true.

See what i mean, just realised i hit caps lock instead of shift, hmmmm, oh also yes i agree completely, google is completely the place to look so point taken, its suprising what you can ask google and still get an answer, i dont think some people realise that if they have a question in mind, then the likelihood is, someone else already asked it, yet they still dont google it, or maybe its just down to laziness that people dont goole anymore.

Mine was a rhetorical question, but it's all good, dude.
Lol, short version: Depending on the battery type you will want to drain it completely before charging or never drain it completely. Let it charge fully overnight or it only needs a few hours.
Seriously, do some reasearch on batteries. Figure out what types there are, how they are different, and what makes them different. each has advantages and disadvantages.
Every battery type is a little different. For our phones will be different than for your rechargable nicad batteries at home, or the batteries in your remote control vehicles.
Bottom line: We COULD tell you, but that would be defeating the purpose. Instead we are pointing you in the right direction to acquire the knowledge yourself. Happy hunting! let us know how it works out!
In simple, it actually causes more harm discharging the battery to empty.
There is alot of do's and donts to preserve the battery,
Info:
The Li‑ion charger is a voltage-limiting device that is similar to the lead acid system. The difference lies in a higher voltage per cell, tighter voltage tolerance and the absence of trickle or float charge at full charge. While lead acid offers some flexibility in terms of voltage cut‑off, manufacturers of Li‑ion cells are very strict on the correct setting because Li-ion cannot accept overcharge. The so-called miracle charger that promises to prolong battery life and methods that pump extra capacity into the cell do not exist here. Li-ion is a “clean” system and only takes what it can absorb. Anything extra causes stress.
Most cells charge to 4.20V/cell with a tolerance of +/–50mV/cell. Higher voltages could increase the capacity, but the resulting cell oxidation would reduce service life. More important is the safety concern if charging beyond 4.20V/cell. Figure
Discharging:
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.
Battery manufacturers ship batteries with a 40 percent charge. The low charge state reduces aging-related stress while allowing some self-discharge during storage. To minimize the current flow for the protection circuit before the battery is sold, advanced Li-ion packs feature a sleep mode that disables the protection circuit until activated by a brief charge or discharge. Once engaged, the battery remains operational and the on state can no longer be switched back to the standby mode.
Do not recharge lithium-ion if a cell has stayed at or below 1.5V for more than a week. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. If recharged, the cells might become unstable, causing excessive heat or showing other anomalies. Li-ion packs that have been under stress are more sensitive to mechanical abuse, such as vibration, dropping and exposure to heat.
And may i point out, this is a community, People ask questions and peoples feedback, the web is not always correct and nor is the information you find.
It takes more effort to argue with someone and to point someone in the right direction, instead of just answering there question.

Indeed, not everything on the web is correct.
But may I point out that all you did was copy and paste text from this page, which donalgodon linked in post 4, and again, I feel I must point out, was actually one of the results in the Google search I linked him to.
The point I was trying to make, and seems lost on you, is teaching people how to look for stuff on their own. No one should just expect to be spoon-fed information. That is lazy to just post a question on a forum, sit back, and watch the answers roll in. You should do your own legwork and research.
As the old adage states: give a man a fish, and you feed him for that day. Teach a man to fish, and he is fed forever.

S3 always connected to the charger

may I leave my s3 connected to the charger for 1 month? someone did the test?
Thank´s
Ed
The main question is actually why the hell would you do that?
Anyway, I think your battery would die pretty quickly from overcharging

I found a very good motion detector camera & was thinking to let my phone to watch my house. But I think is to dangerous.
Thanks anyway.
It's perfectly safe. Lithium batteries lose accuracy over cycles. They are best stored charged than depleted.
I wish I stole my HTC M9.
Hi shivadow,
so....do you think is safe, do you know where I can read about it?
where I can take more info detailed?
Thank a lot
There is a chip in battery that prevent from overcharging, but phone will be almost all time hot, what is not good. It probably make it live short (phone and battery).
For this kind of using better search for a micro PC - Raspberry Pi or somethink like that.
