Is it possible to connect charger without battery so that i can use device all day and avoid over-charge or possible battery damage?
Beautiful just Beautiful
Guys i have another one for all of you
"Is there a way that i can use my Phone without connection so that i will have no bill charges ?"
Batteries in Tornado can (even should) be charged often Don't worry about it
Yeah, over-charging is no problem. It'll stop charging when it's full.
This does raise an interesting question, one I haven't really bothered to try but have just now become curious about. Can you plug the phone into the wall, sans battery, and use the phone still? Or will it only function, plugged in or not, with the battery installed?
Phone turns off when you get battery out :/

LOL, I just tried that last night, and... ohh Noo it don't even turn the power light on w/o a battery... so @Amaric: Keep charging it!
I am aware that phone is not working if you take out the battery and connect it to a charger. I was wondering if there is some kind of a workaround.
My plan was to have phone switched on for months with wireles ON too. That just can't be good for battery and it could even be dangerous.

Do these tests, and post results
Turn off power savings on Wi-Fi and leave phone ON, doing something over the internet, just idling, so that the LCD is off. Say for example: acting as router.
Conditions:
1. Phone w/full battery -
2. Phone charging w/full battery -
How long did he battery last? How did the phone temperature change? What would you guess would happen in 48hrs of usage?
EDIT: My experience with Wi-Fi is that it drains more power than the charger output. Temperature raises substantianlly w/o LCD, gets extreamly hot w/LCD on. So what would be the options?

when im booting linux and the phone is charging you can take the battery out but the phone will still be on nice

Is this a joke? If not, then some change to a software (OS) could do the trick.

my opinion? If it does stay on after removing the battery, then it'll do the same if you have the phone on while running Windows, and charging and remove the battery. Battery charging is not handled by OS, its handled by Hardware.

Does anyone else think this is true? I think it would be unlikely that having the screen off but wifi on would use more power than the wall adapter provides.
I suspect that you could jumper the battery connections to mimic a full battery, but I am not going to try.
I think you can put resistors to mimic the internal resistance of a battery, but I wouldn't recommend it. If anything goes wrong you might burn out the charging/power control circuit which probably would turn your phone to a brick.
Oh, and the whether it charges when plugged in and using WiFi depends on your charger. I've got a 6V 2.4A (15W) charger for my phone, good luck using up all that juice with a Tornado. That thing easily charges my TyTN with HSDPA (3G), WiFi, Bluetooth and screen active.
15W is more or less what my laptop uses under normal load
Im new to windows mobile and i noticed that everytime i connect my fuze to the computer it indicates that it is charging, is there anyway that i can turn the "charging" off? because like this it kills the battery slowly.

are you sure about that? i thought all these batteries and phones nowdays, were quite good at managing this all by themselves....
we're really still in an age where us as users have to actively baby sit our batteries?

Are you meaning it kills the battery on your pc? (i assume its a laptop if thats the case)
There is an option in start>settings>system(tab)>power to stop charging when connected via USB.
Charging via USB is a great feature and im positive it doesnt DRAIN the battery on your fuze?

i thought perhaps he was under some sort of misconception that the battery on the FUZE keeps charging even after its full while plugged into USB, and this somehow 'damages' the FUZE battery, or slowly 'kills it' ... ur interpretation makes more sense though

I thought so as well, I thought that the Fuze would stop the charging once full but I am not positive. I know most of my las Li-On devices still suffered from burnout but none were as fancy as the Fuze.
Makes sense that it could have just been draining his laptop faster though
i was referring to the battery of the phone, before baterries used to suffer i think the term is called "memory effect" which caused the batteries after a while hold the charge for less time, this was caused by always charging when not needed.
they say that the new batteries dont suffer so much this "memory effect" but from my experience that is not true

Lithium-ion batteries do not suffer the "memory effect" that the older batteries do. They also do not need to be drained fully a few time when you first get them to condition the battery. Draining the battery fully actually is bad for the lithium ion batteries and can significantly effect the life of the battery itself.
The original question has been answered already, and the information regarding the batteries is already available elsewhere so i am closing this thread.
Hello everybody, I own an HD2 that is alway connected to a table cradle (connected via USB to a PC) during the day when I'm in Office. I wonder if exist an app that allows to manage the battery charging: I explain...I'd like that the HD2 AUTOMATICALLY "turns off" the charging when the battery is fully charged at 100% and automatically "turns it on" again when the battery charge reaches a given threshold (60-50-40% or something like that). If you own an IBM/Lenovo Laptop I'd like something like the power managment app. Of course the data syncronization HAVE ALWAYS TO STAY TURNED ON regardless the chargin of the battery.
Does it exist somehing like that?
Thanks and regard
Andrea
There is a setting that allows for the battery not to recharge when connected to a PC. Other than that, I completely fail to see what would be the purpose of what you are asking.

thanks for your answer! I already know the setting you're talking about, but as I told early I'd like something that manages this setting automatically. The purpose is to avoid the decreasing of the battery lifetime caused by letting the battery itself "always" connected to a charging source. For example in the Laptop PCs it's better to unplug the battery when the laptop is conncted to an external power source/charging unit...
Thanks

Most modern devices (and, I believe the HD2) actually disconnect charging when the battery is at 100%. The green light doesn't mean that your HD2 is still charging, but that it's at 100%. Therefore I don't believe you actually shorten the battery life by keeping it plugged in.

I did believe it too but I have an app wich monitors the battery temperature and still when the battery charge is 100% its temperature remains "high" (35 grades degrees) as long as I keep the device plugged to the cradle. I see the same temperature value when the battery is actually charging...this fact have made me change my mind about the fact that the HD2 disconnect charghing when 100% is reached...
Its not the battery which is getting hot, it's the phone.
If I had a lithium-poly/ion battery that was reaching 35C I'd be very worried!
If your app is showing the battery at 35C, turn the phone off, remove the battery and it should be cool to the touch.
If it's hot then you have a problem.

Heat will decrease the life expectancy of the battery, but so will deep charging rather than top ups, remember with non-NiCd batteries you don't get memory effect, so the only reason to do a deep charge is to recalibrate the software battery meter.
Of course leaving the battery sitting on a shelf will also degrade it's capacity, they start to degrade as soon as they're produced, so buying a spare and not using it until your original battery dies is not a good idea, better to buy a replacement battery when the original starts failing.
HTC's batteries actually seem very reasonably priced too which is refreshing.
I noticed that the charging rate was abysmal when charging from a usb port. So I looked to see if the phone was sleeping while charging. CPU spy says it doesn't (both wall charger and usb port). Is this normal? (i.e. does every android phone do this?). I'm thinking if it was sleeping it might charge faster since it wouldn't be using so much electricity.
UPDATE: Using current widget, I see that the phone is getting ~150-250mA while charging via usb port. I'm pretty sure a usb port puts out about 500mA, which means about 1/2-2/3 of the current is being consumed by the phone not sleeping. No wonder it takes forever for the phone to charge via usb. All my previous phones charged pretty fast via usb.

Hi, Are you using a custom ROM? There is an option in my custom ROM (ARHD 6.7.0) to stay awake while charging, which can be checked/unchecked under Settings -> Develop Option menu.
It depends on the PC. The MAX current is 500mA but might be less, hence some USB disks have an additional USB connector to get more power. Mind you if it's a reasonably new PC it should be 500mA.
The mains charger should have a rating on it, hopefully 1000mA, try that and check in CurrentWidget. Also bear in mind that the charging current will also tail off as it gets close to being fully charged.
Have you ticked un-ticked the box "No Log in Charge" and also ticked "Force Log in Sleep Mode".
If you click on the battery graph in setting does it show the phone Awake 100% or does it have some sleep periods ?
EDIT:
Are you looking at the figures from the log file or the widget on screen ?
I had a quick look at mine (unfortunately I can't be certain which was mains or USB from PC as the phone was on both randomly.
Anyway max I saw was ~900mA charging the tails off as expected the closer it gets to 100%. Seems to start dropping the charging current 900mA @ ~60%, 150mA @~80% then close to 90% it's dropped to 23mA !!
EDIT2:
I know when I was using CM7 the ROM purposely showed fully charged at 90% to avoid overcharging and destroying the LI-Ion battery. It would continue to charge fully to 100% but at a much reduced rate.

You cant get deepsleep while charging, thats based on my experiences, but maybe i am wrong, cause i dont use cpuspy for long time,.

I didn't turn on the force fast charge because I didn't know what it was. Now that I know, I might turn it on.
Also, stay awake while charging is not checked.

Can't use the mains charger because it is a Hong Kong adapter and I live in main land China (different outlets). Don't recognize "No Log in Charge" and "Force Log in Sleep Mode" so I'm going say I haven't done either.
Also, I became aware of the problem while trying to charge the phone via my Asus Transformer usb port and the usb ports on the computers at the school I teach at. The phone would say charging but would never actually increase the battery percentage. Those both probably have pretty low amperage. However my home pc is fairly new, and charges other phones fast, and charges my sensation at decent speed.
I use cpu spy to check to see if it sleeps. Charging via usb port or wall adapter (non-HTC) cpu spy never shows even 1 second in deep sleep, it just stays at 192 MHz. Unplug the phone and it will go straight into deep sleep no problem. Looking at the History Details for the battery, it has some non-awake(sleep??) periods during charging.
So, do android phones (or specifically the sensation) go into deep sleep while charging? I just need to figure out is this normal or not.

Thanks, that is exactly the information I need.
UPDATE: Now that I know my ROM/Kernal doesn't have any problems, I've moved on to testing cables/ports/chargers. Finding huge differences in the charging rate between different cables.
OK on CM10 I just charged from 68% to 100% and the phone was NOT awake during the charging period.
I'll repeat the exercise later on 3.33.401 stock but expect to see the same.
Are you sure it's not one of your apps that's causing the phone to stay awake ?

It's not "awake" i was looking at, I was looking at deep sleep. The phone can be "not awake" and at the same time not be in deep sleep. Awake is when the phone is on and doing things, even when the screen is off. Deep sleep is when the phone is hibernating. While charging, the phone is not awake, unless its doing something, however it doesn't go into deep sleep either. It just throttles down the CPU speed to the lowest speed and "idles" so to speak.
Yeah, so I solved my problems. Thanks for the help.
Does anyone know how to fix it? (don't know if it's an issue indeed)
I just wanted that my phone goes to deep sleep as I eventually use Powerskin (1500mah external battery) and it lasts like 8 hours (cpu keeps at 192mhz, doesn't get into deep sleep while charging). So, I'd like to avoid unecessary battery consumption.
So as of late I have had to use my M8 for internet.. playing games and the like, now obviously when it plugged in.. it also charges.. I have looked around the settings on the phone and also the net and not found an answer to either of these questions.
1. is it hurting my batt? long periods of being plugged in (and charging!)
2. can i turn it off? whether its hurting the battery or not I'd still like to know if it is possible..
I am running a version of Venom's ViperONE ROM on it.. I figured they would know more.. so I may have to post to them directly.. but I figured I'd ask here first,
Thanks in advance:good:
1. define "long". Having the phone on a charger constantly degrades the battery. Li-ion battery have the longest life span if you let them discharge to about 20%, then charge to about 80% and repeat.
They don't like over charging and neither being totally depleted. But unless you abuse your battery the difference between a battery with perfect charge cycles and one with less than perfect (normal use) charge cycles is probably hardly noticable over the typical 2 year life span of a mobile phone...
2. turn off what? It doesn't need to be connected to power to have internet connectivity....??
