[?]Is it possible to disable USB charging like winMo - Nexus One General

I just wonder is it possible to disable USb charging in Nexus One

until now i have fond nothing about this
i rely need this because i plug my phone for tethering at work
and the battery is 100% already there should be an option for this

Not sure why you need this, when the phone is 100% it will stop charging and draw power from USB while plugged in, surely this is preferable to rapidly draining the battery while being tethered?

the problem that i am using the phone for 8H for tethering (all the work time)
and the device get toooo hot i want to stop the chargeing ntile the phone battery dry than i will charge it again

From what I've seen from other threads on the subject of charging, doing what's practically a full drain and then charging again will not only create more heat but may also shorten the life of the Li-On battery.

It's not that making it 0% before charging it kills the battery life. The Lithium Ion battery's life cycle is poor and that's what it's infamous for. What makes it's life shorter is the amount of times you charge it. When you charge it all the time you're reducing the life of the battery greatly. This should help with that subject.
As far as disabling USB charging, I've never heard of it and I don't think it would be possible. If it is, that's great. My question is; why don't you use WIFI Tethering? You get the same results and you don't have to charge to use it.

If your phone gets hot while tethering, just use SetCPU to slow it down a bit... or maybe use a task killer to get rid of some of the background tasks. If your phone's already charged to 100% then it shouldn't get hot just from being plugged in.

SetCPU wont have any effect on this because the battery is what is getting hot from charging.
I still don't understand why people even use SetCPU anyways.

Couldn't you modify a USB cable and clip the power wires? I know it might be a hassle but it would be a sure fire way to keep it from charging and I believe the data connection would still work. That way you could have a true data only cable.

I've found that it almost doubles my battery lifetime by reducing the CPU speed when the phoneis on standby to almost minimum... Otherwise my phone doesnt last all day (from 8am to 1am)... It is actually one of the most useful apps on the nexus for me at the moment...

Why not? Throttling my max clock while in standby and setting a max clock on under 40% battery, has helped me increase my battery life about 2-4 hours every day...

Most people misunderstand how a processor works. Your phone automatically idles at 386mhz. Setting a MAX does nothing but limit the availability. A 1ghz processor doesn't run at 1ghz consistently. A 1ghz processor just means that 1ghz is available. If your phone is sleeping then it's not using very much at all. The only reasonable change would be to change your MAX to something lower for Screen On or setting the MAX to like 100mhz for screen off. Other than that, you make no changes.

Yes, but not more often than that (I've heard numbers like every 50 cycles (~2 months)). Unlike other types of batteries, LiIon batteries do not like the full discharge / full recharge cycle.

Take the battery out. The phone will run off of USB power only. It works with my old G1. I haven't tried with my nexus though.

USB Connect without charging Galaxy S
I just tried 'snipping' the power wire (Red) on a USB cable, now nothing happens when connecting the cable, it's as if the devices (Samsung Galaxy S and Nokia E72) need the power line to connect for data transfer.

in fact that's not a good a thing to do, the worst ennemies for liion batteries are heat and voltage stress.
voltage stress results from either full charge or full discharge , the optimal charging pattern is 10% - 90% (but partial charges in between are of no harm at all)
by all means try to avoid full battery drain and/or keeping charger plugged after full charge.
following these guidelines you should more than double you battery life span

As far as I know... it doesn't matter with actual batteries.
If I look at my notebook (which is over 2 years old) where I charge and uncharge all the time - the battery works still fine.
I'm not sure if it's worth the work - if the battery life sucks after a few month (years..?) - you just buy a new one for a few Euro/Dollar. (Man! You don't have an iPhone...lol)
I've never had a mobile phone for more than a year - so I wouldn't care!
(But I'm pretty sure the actual batterys don't care either!)
Li-Ion batteries don't suffer from the memory effect in the same way as Ni-MH batteries do, so theoretically it won't harm to charge the battery whenever you want to, regardless of it's charge level at the time. They do have a limited amount of cycles though, a cycle is when it goes from full charge to full discharge. It's eventually going to wear out no matter how you treat it.

so basically what your saying is Li-Ion batteries cannot over charge and then eventually start to decrease in total battery life?
If so, does that mean my T-mobile Wing's battery just crazy?
It would have exploded if it could "overcharge".
li-ion has a limited battery life by itself, which doesn't depend on usage/charging.
but charging can shorten the battery life if done wrong. charging cycles vary depending on how empty the battery was. it looks something like this: (see wikipedia/google for specific numbers)
95% 1000000 cycles
90% 100000 cycles
70% 10000 cycles
50% 1000 cycles
30% 100 cycles
10% 10 cycles
0% 0 cycles
actually you can never reach below 30% because the battery or phone will protect itself whenever that point is reached and turn itself off.
conclusion: charge whenever you can!
ps: li-ion for cars only discharge to 70%, so the battery can actually be used for longer than 2 years unlike a cell phone battery, where it can be discharged to 30%.
Guys, this is silly. The battery will work with no problems for 2-3 years. Then you can buy another one or, more probably, another phone. There is no point whatsoever to not charging it when connected to the computer. As a matter of fact, this will only reduce its lifetime.

How to get full potential out of your extended batteries!!!

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!!!!
Ok are you using juice defender for it or any application that save battery life

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.

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.

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.
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.

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.
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.

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.
The basic process is to charge at constant current until each cell reaches 4.2 V; the charger must then gradually reduce the charge current while holding the cell voltage at 4.2 V until the charge current has dropped to a small percentage of the initial charge rate, at which point the battery is considered 100% charged. Some manufacturers specify 2%, others 3%, but other values are also possible.

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!

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%.

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.

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.
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.

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://forum.xda-developers.com/showthread.php?t=876590
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 ).
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.

Do you charge the phone via USB (computer)?
This is a common issue if you use your conmputer as a USB charger. Computer USB can't supply enough energy to your phone. The USB current is too low only 0.3mA or 0.5mA.
Just use the ORIGINAL charger or other well-quality charger with higher current (700mA+). This is enough for both charging and playing. Of course the charging will take longer time while playing.
The higher current will not damage your phone. It will charge your phone faster.
NotOriginal and cheap charger may have low current-output or the charger is sometimes bad designed than the phone will recognize it as i computer USB. (if bad designed than the phone takes only low current even if the charger is able to supply more)

Not glad to hear that. I have never (only 2+months with X10) observed a problem with the original charger while using the phone (playing, GPS or wifi). Sometimes a bit warmer, which I consider to be common.
In general is the reason the same. The phone requests more then the charger supply
I think it's a software issue.
The bluetooth used to eat away at the battery but BB.67 sorted that out.
Wifi never was a problem for me.
But the GSM Radio is a absolute battery PIG.
It's using so much juice it's scary.
I hope SE sorts out all the ****.

Well it is probably also related to the signal level..? I use BB 58, never use BT. The GSM signal is almost full at home (while charge).
BTW: To charge the phone with the original charger takes tightly 1h for me. (from +/-30% to 100%) (not using the phone)
Mine's was not charging above 88%, but then I deleted batt. stat and it went to 98% and then 97% and then again to 100% then I used an app called Battery Calibrator and everything is fine now.
Depends what game your playing. Pocket legends with screen and volume on full, wifi connected, overclocked and set performance etc etc I can use a fully charged battery plugged in and drain it in 2hours. Its just supply and demand, the charger can't keep up.

But also you need to turn off Wifi for battery save and keep u away from radiation

I checked again and I think its coming just from the battery.. those terminals. My battery never reached over 45 C and usually operates in 32-37 C and phone does not reboot at all by itself, may be I am just over cautious. Also, it is X10 HD (newer batch).
May be there is something wrong with the battery as I have flashed many roms in last few days and had deleted batt. stat everytime I flashed it. Enlighten me on this stuff. Should I undervolt and underclock CPU to avoid any damage to CPU?

Wireless charging. Over use of

Is it best to do long charges then let it drain, or is it safe to for example use the phone ten mins and put it back on the mat for ten then use again and so on. Does constantly charging mess things up?

Your phone's battery should be fine as long as it's not overheating.
Most of today's batteries are built to last, which means if you are actually abusing wireless charging, you will start noticing not before 1 year from now(estimated.). And by then, most people have switched their devices. Therefore, it might be damaging you battery, I'm not an expert, but you should not start seeing any bad impact on your phone in the near future.
Other people's opinions might be more helpful than mine, but you should keep this in mind.
Cheers for your opinion. All are greatly appreciated.

Almost no one charges batteries the ideal way.. well, because it's inconvenient to do so. Fortunately battery technology is getting better every year, batteries take longer to wear out and are (slowly) getting cheaper to replace when it comes to that.
The ideal way to charge a battery depends on the type of battery. The S5 uses a lithium ion batteries. Ideally you would charge a Li-ion battery slowly, not deep cycle it, protect the battery from hot environments and (idealy) stop charging around 85%.
Heat is the major enemy, battery life is shortened by a factor of two for every 10°C increase above 25°C. High cell voltages and cycling would fill out the top three list of things you'd like to avoid to maximize battery life.
So what does all that mean? Frequent wireless charging is beneficial if your battery charge is < 85%, because you don't want to deep cycle and slow charging (which wireless is) is better than a fast charge cycle for battery life. And a moderate stress if you are charging it when the battery is > 85%. Do what you can to avoid high heat e.g. don't leave your phone in a very hot car on a sunny day if you can avoid it. And if you go Skiing or store your phone in a freezer for some reason.. let it warm up a bit before trying to charge it.
Most of us will charge our phones even if the battery charge is > 85% though because we want to maximize run time, even though the higher voltages above 85% are a detriment to battery life. It's a trade off between utility and battery life. Battery life is conservatively specified around 500 charge cycles these days.. but that is a loosely defined term with a lot of associated variables. Depending on how you use your phone.. your battery may go six months, a year, even two years before you notice that your run time just doesn't cut it anymore.
I'd say don't worry about wireless charging. Charge it as frequently as you like. But try to keep your phone cool (out of the sun) when you can.

Cheers for that appreciated. However wireless charging on my setup involves a fair amount of heat
Wireless charging is relatively inefficient. Which means that there will be some waste heat generated. But it varies substantially on the brand of charger and whether you are using an resonant or inductive design. My wireless charger produces minimal heat.
Unless you measure the temperature.. it's hard to gage whether the heat from yours is a serious issue or not. Mine increases the surface temperature ~ 5C.

Would you mind sharing which charger you use?

How good are you with Orcad and a soldering iron?
I built my own @ 3.57 Mhz, which is also a non-standard (but very efficient) coupling frequency.

Is it best to do long charges then let it drain, or is it safe to for example use the phone ten mins and put it back on the mat for ten then use again and so on. Does constantly charging mess things up?
Thanks.

Lithium-ion battery nowadays does not have memory effect. So constant recharging and disconnecting is fine.
Cheers folks.

Charging advice

Hello, so I just got a new Moto X style about a month ago, I need your advice from something, should I charge my phone at 30-40%? if yes then will it have long term damage/worn out my phone?
Thank you
The golden rules are
Don't ever go below 10%
The battery is happiest (most chemically stable) around 40%
Try to spend as little time above 90% as practically possible, especially when charging/using the device. This means never leaving the device plugged overnight
Avoid heat i.e., Do not overtax the phone in an environment like a small, hot room; Avoid simultaneous charging/GPS in the car with the phone in direct sunlight
To combine the last two items, especially avoid high temperatures at higher battery levels. This will degrade the battery very quickly
I've also read stuff about the discharge depth. Something to the tune of discharging the battery from 80% to 60% before charging is better than discharging from 80% to 40% before charging. I've never paid that much attention, because nobody wants to charge their phone 3 times a day, but apparently topping up is better than charging from near empty.
I've had my Pure for a little more than 6 months now. I have been consistently plugging in when my battery hits 30%. My battery life is as good as it has always been.

IMO charging overnight dont do anything to the battery, phone stops charging at 100% and start to use energy from the charger, but im with you with the 10%.
I think all these "rules" are all just bunk and superstition... If you make it through the day, plug it in overnight, and start again in the morning, if not when the battery is low, charge it when it is convenient, don't be scared of "overcharging" as that isn't really possible anymore with electronics in batteries and devices. The device is meant to be used, not babied.
These lion lipm battery do not actually ever charge to their full capacity. This is by design so 100 % is really around 80 in reality and 0 is around 8 to 10%. Again this is by design the chipset monitors the battery temperature and charge load as well as discharge load and compensates for heat and load. All this crap about charging at different rates and in different situations is bunk written by people that don't realize battery design is constantly changing. And since quick charge 1 things have changed a ton.

Sooo does this mean I can charge my phone over night using the Turbo charger 25W that comes with the phone?

Yes.
I won't argue with anyone here, but I would advise all of you to research lithium ion battery technology. The OP asked how to prevent long term damage to his battery. My friend and I bought our Pure's at the same time. I charge the way that I indicated, he leaves his phone plugged in all night, every night. We're both on Verizon, and I've noticed that his battery drains much more quickly than mine does.

Take care, all.

Have you verified that he is running exactly the same apps as you with exactly the same service throughout the day. If not then your supposing that charging is the issue is simply a guess. The only way to determine exactly would be a to set them up exactly the same and run them exactly the same in exactly the same conditions for a week or more and log the battery life..

I run more than he does. He is older, and does not use social media. I use FB/Messenger, Snapchat, Twitter, and Instagram with push notifications enabled. Our standby battery drains are very different from 100%. His device hits 90 while mine is reading 94. The devices are physically next to one another. I only know this because he's at my house every weekend. He always plugs my phone in when he plugs in his even though I've told him not to a hundred times. There are probably other factors involved, but I always attributed the difference to him constantly leaving his phone plugged in for hours on end.
Have you looked at his screen timeout? Screen brightness. Or checked to see if he has a misbehaving app? Does he have wifi at his house ? Or is his doing all it's updates at your place? See there are tons of variables that have nothing to do with charging that are simply more likely to be causing the issue you are noticing

I mean, I wouldn't describe what I'm observing as an 'issue'. I understand where you're coming from though. I have gone to war against errant battery drains in the past. Lollipop/Marshmallow's mobile radio drain is something I surely won't miss. He does have Wifi at his house for app updates and such.
Just for the clarity's sake, we're talking about:
2 identical devices, running the same version of Android and the same ROM, which are connected to the same mobile and wifi networks, in the same physical location - so service quality is not a variable, unless there is a hardware issue. Both devices are [simultaneously] charged to 100%, and then they are unplugged and their screens remain off. Upon checking both devices a little while later, mine is at 94% while his is at 90%. My device is encrypted, rooted, has custom kernel settings relating to the governor, read ahead, and entropy, and runs various GCM social/messaging apps, and has an extensive Tasker setup. His device is untouched. Both devices have been fully drained and recharged at least once in the past 60 days.
I have looked at his battery usage, which I log with 3C Toolbox. There is no excessive drain from any apps, the cell radio, the kernel, etc...
Regardless of what is causing it, the observable evidence is curious.

Not saying you are wrong, but the scenario you give is at best circumstantial with the given info. It does not account for other factors such as apps installed, network connectivity, how the phone is being used, etc.
Screen brightness can drastically change how long until you have to recharge. Mine is usually only 1/4 of the way up.
