Hi everybody.
To get the most out of my battery I always wait until my device shuts down due to lacking battery. The I chargt it until it the end and the battery displays 6+ houres.
When I recharge the battery before its empty I only get 4+ houres when its full.
I also read that the battery's lifetime is increased by only charging it that way.
My problem is the cradle that charges it everytime I sync.
Is there a way or tool to switch charging on/off for the cradel?
Thanks alot
Alex
The way I understand it, modern batteries do better when charged regularly in small increments. They do very badly with multiple deep discharges, which can actually damage them.
So I would actually disagree with you that what you are doing is a good idea.
If you still decide to do this, the simplest way is probably a manual activesync via bluetooth, using a dongle, as it actually charges via USB too.
Surur
Right the bluetooth thing would be a good idea.
And you might also be right that you should not charge it in such an extreme way...
I read this an a PC Magazin.
I don't know if its wrong or right. the only thing I know is that the battery lasts longer when I charge it thta way.
Thanks
Alex
The battery in the xda2 is designed for constant charging, I dont see how you would get more battery life because if you acheive your desired aim the xda2 will be discharging during sync and will give less battery time than if you let it top up the charge.
I read that Ion battaries have only a limited number of complete chargings bevor the are broken...

Hi, do you have any workaround how to set my Legend to not charge the battery while it is connected to PC's USB port?
When I want only to transfer some files to SD card and plug the device into USB, it starts to charge. It is very important for me because it continuously damages battery if this happens several times only for some minutes. In Windows mobile there is a great option to not charge when device is connected to USB. I hope there is an option to do this also on android.

I'm pretty sure the batteries today doesn't take any harm of this type of charing. Correct me if i'm wrong

Hmm, on the hand way I am pretty sure that it harms the battery ... 1minute chargings are not good for battery...
I am also certain it DOSEN't damage the batteries...
However.. There are several reasons to disable charging when connection to a PC.
For instance, using a USB hub without additional powers, the drain the phone will put on the hub, will make the rest of the stuff connected to it stop working.
Or simply just to preserve the batteries when using a laptop. The batteries on laptop is bad enough as it is, so no need to put more drain on them...

*replace ! with .
Lithium-based batteries (like those used in basically every single mobile phone now) love to be topped up constantly. In fact, they suffer permanent damage to the lifetime of the battery if they are ever empty. Don't worry about charging them for a few seconds are a few hours, as long as you don't let them go flat.
Lithium batteries will only work best for a few years from the day they are manufactured (not their sale date, by the way). You'll notice if you have an old mobile phone or iPod that they'll start to run low faster and faster the older they get. This is just a consequence of the chemicals they are made of. It's also why some people refuse to buy Lithium-powered devices that don't make it easy to replace the battery (like iPods, for example).
Also, Lithium batteries don't hold their full capacity right away. They have to be charged for 300% of their capacity for them to be running at peak, although you do not need to do this all at once. This is why some devices come with advice that you discharge them completely a few times right at the beginning. I never do this, because as I advised earlier you do not want to let them go flat. Instead, I charge it up to 100%, use the device down to 50%, charge back to 100%, over and over, since each of those charging sessions contributes to the total 300% necessary.
Nickel-Cadmium batteries were the old sort of rechargeable batteries used in other sorts of devices (toys, remote controls, etc). The best care advice for them is to leave them in the charger until they are needed, and use them until they are completely flat before charging again.
Hi all, there is a way to turn off the charging function when using USB ,
1-install FdcSoft TaskMgr from here
dotfred.net/TM/FdcSoft_TaskMgrv3.3_WM6.5.cab
2-go to Devices--->$device\BAT1(BAT1 and stop this service
3-thats All
To Use charge restart this service
hey thx for the tips! but after stop the service my o2 keep saying batt low...
Is there any reason why we would want to turn off this service?
I heard that it keeps your battery in good shape

I'm not so sure about that... I've always charged both my O2 and the O1 before through usb and the battery has always been fine.
Actually, I even noticed that charging through usb takes longer but once it's charged it also lasts longer (this happened on the O1, haven't made the same comparison on the O2 yet)
Dunno if plugging / unplugging the usb cable too frequently can have some sort of ill effect on the battery life, but it's not like we're plugging it every 10 minutes is it?
Never had a battery problem with a "normal" usb usage and usb charging enabled so far...
Yes but not anymore

It's always good to drink all the juice so the battery don't develop a offline or fake "memory".
Also the multi cell assembly insde the battery praticly don't allow batery memory anymore.
Thx for the reference
Regarding battery life
Hi,
Actually, for a battery it depletes it's life every second. There is no way of preventing this But we can extend the service life. For example the most basic rules:
1-Do not charge your battery unless it is almost empty
2-Avoid deep discharging (this is not possible with a PDA coz it has an early shut down routine)
3-Do not overcharge the battery (also this not possible, coz there is a voltage limiter by hardware)
4-Do not leave your battery in a high temperature environment (for example in a car during summer, we are using chemical-reaction batteries)
the rest is do not puncture, do not short circuit boola boola boola
ok, finally while using your PDA with a USB charging interface, it should stop charging when the battery is full (Even my mother's old nokia doing this)
Plus, how much it costs for a new battery? only few bucks.. ehh.. (not for an original one ofcourse)
PDA batteries, in most cases, are 3.7volts (charging voltage is 5volts by USB) and 1200 to 1500mAh (for the ones who doesnt know what is "mAh": it is the capacity of the battery and it means if you pull for example for a 1300mAh battery, 1300 "mili ampers per hour" it will deplete. Some of my friends they are using 3.7V 2000mAh batteries while their PDAs supplied with 1230mAh batteries, thus, standby time goes up to a week. They are not using their originals ofcourse. I dont understand why manufacturers are not supplying PDAs with these kind of batteries by standart. Even a chinese made battery can be so efficient. (I am using a chinese one, my original battery is 1300mAh, i could find 1500mAh same battery)
I spoke to my friends, they are not charging their 2000mAh batteries via USB/charger while battery is in the phone. Because there is an internal electrical resistance of every battery. May be PDA's battery charging circuit get damaged! Because of this if you plan to use a high capacity battery, charge it seperately by using another charging equipment.
Finally when you want to sell out your PDA install the original battery (which you have never used before hehe ) and get a higher price
This might be some really big idiotic question, but what if the service is down and the battery drains and the phone shuts itself off, will it turn on by connecting the charger to the phone?
I ask this because with the service off even the real phone charger wont work (at least while it is on)!

Hi guys I have been facing a strange issue whenever I install any windows phone 7 rom no matter what i do the phone refuses to charge using a usb cable or charger if i go back to android same usb and charger work fine for charging please advise
i noticed that too. on my pc it charges either VERY slow or not at all. because i left my hd2 on usb for 2 hours. it was only halfway full. i though i was going crazy good thing im not the only one who noticed this.
on the wall adapter it charges fine.
For me the above mentioned issue exists on all the roms
I think i found a workaround for people having issues while usb charging on wp7
This a bit of a hassle and has to be done everytime u see that the phone is not charging via usb
uninstall the driver for windows phone device from device manager and then connect the phone it will reinstall the driver and the led will turn red if it blinks that means its not charging
If anyone has this issue and needs detailed steps please let me know

I have never heard nor experienced the phone not charging on WP7 on USB. The HD2 takes longer than 2 hours for a full charge if it's at a point of total discharge or close to it. Even on WM 6.5 the HD2 usually takes about 3-4 hrs to fully charge after near total discharge.
Secondly, a blinking LED during charge (whether PC or wall) means your battery and phone are overheated. Overheating happens if you are using the phone while plugged in. Even if blinking it is still charging. Best to unplug until cool..then keep charging and not use the phone.
Buy a second battery and external charger.

Wow thanks a ton for the info
but i have a question if i connect the phone to usb the battery blinks and while connected the battery tool shows battery getting drained as well at the top the battery icon shows that the phone is charging. and then if I immeadeatly connect it to the wall charger the blinking goes away and battery tool shows charging active so what can be the issue any help would be appreciated
Also i have tried almost all windows phone 7 roms and my normal drain is -300 to -500 have tried rom with 5.51 and 5.12.50_02 radio as well along with the camera trick still the battery drain is high
Yesterday i installed wm6.5
task 29
install magldr
clear sd mbr
use last 24 nand
install wp7
booted and did camera trick
entered flight mode
still the drain is -150
I love WP7 and dont wish to go back to android sorry for the long post please help
WP on our Leo doesn't have a clue what its doing with the battery, its been an issue from the start.
best bet to get the most out of your device is to get yourself an external charger and spare battery.
even if you do get it charging via USB or the wall adaptor, it might not charge up the device, it might say its full but is only half full, or it might say it half full and its actually full.
UP! Your advice to bring with me to anywhere a package of batteries?? Jesus Christ, I can't believe that nobody cares much about this problem from devs, otherwise there is no point to make a new rom every single day.

I really don't think its a "nobody cares" situation. We can be pretty confident that if a solution was at all possible it would have been found and implemented by now. The devs do a great job and i for one am blown away by the roms they produce and offer to to us free.
Every smart phone on the market has battery life issues which tells us even the manufacturers cant really get a grip on the issue either.
You could always hack a li poly bat to fit the HD2, of course that's only if you accept the risk it might swell up and catch fire while charging
i dont think kicking the devs and other forum members will make you many freinds.
Good luck

its not about not caring, there are two issues at hand.
the first one is the phone wont charge when turned off, this might be fixable.
the big one is the battery controller, a battery in a phone has a small IC that controls the charge, temps, stats etc. The issue I believe is that the driver which WP users to control the battery controller isn't designed for our device.
The HD2 is similar to the HD7 but it is not the same. The issues we have with it are likely because the driver is either for another device or a basic test driver put together to "make do"
creating a driver isn't a matter of slapping a few files together. So your choices are to
A, give up on the HD2 WP7
B, Make do with what you have
C, Grab a spare battery and external charger
D, Fix the issue yourself, given that some of the most talented folk on here hasn't done this yet suggests this wont be easy!
Flashed 2.12 radio, can't say it's good now, but much better than was with 2.15. I think 2.12 + new battery with bigger capacity (2300) = pretty good solution for now.

except your 2300mAh battery probably wont work at all.
Theres been reported issues with extended batteries either A not working or B having issues, such as only charging part of it.

If your phone shows only a half charged battery icon after charging for the full few hours, shutdown the phone and reboot. Doing this shows the correct icon and can confirm via battery status app or battery tool app.
The thing is when you flash a new ROM, it takes the battery, phone, and WP a couple of charge/discharge cycles to get sync'd up and show the proper charges. The key is to let the battery drain until close to total discharge (don't let the phone shut off because of battery or you'll be hosed) then charge a couple of cycles.
Getting a spare battery and external charger is always a good suggestion no matter what.
Yes, restarts are always handy to get full charge, if you do kill your battery so you can't boot to windows, try put phone in bootloader, or magldr, it will charge in there, give it 20 min and windows will boot just fine

have you tried a different usb cable and ports
or tried turning usb debugging on
Bro, i tested all ports, all cables... I cant find usb debug on stock rom... I even uninstall the app that i have instaled yesterday.... Don't know wat i can do.... Im not willing to do a factory reset.
Let me explain even better... I can charge my phone in the normal way... but i cant keep charging my phone on usb when i'm using the phone while charging.

Go to settings, about hit the build number 6 times that will activate developer opinions USB debugging is in there
There is probably a hardware connection issue. I believe you don't need a driver just to recharge thru usb. Are you able to make data connection to your pc using usb cable?
Your USB port will charge at a slower rate using PC-USB , if you're tethering the phone is probably discharging faster than the computer is charging - if you're on KK for example screen on will use 1700MHZ if in use so quite a drainer, Failing that, it's possible it's a faulty USB from either the computer or the device.
I'm able to make data conection with my phone and usb...
And like i said, I didn't have this problem until today... I think it coz i install crack app, or put a new sd card.

It's possible they may be causing it, the cracked App could be running anything in the B/G of your device keeping it awake hence USB not charging it as it's in use. Uninstall it (and support the Dev by buying it!!) see if it makes a difference.. Another thing is check your wakelock/battery use.. Media scanner might be eating up your battery.

Probably its Media scanner, coz I put 4.5gb of music and 1gb of photos and videos yesterday... How can i control it ?
You have to let it index the files - it varies on how long it takes, but it should reset OK on your next battery cycle at least.

Index Service and google services are consuming the most of my battery... So I have to w8, correct ? But it takes soh long, like days ?
OK, this is very simple but you need to figure out which of the following problems is yours:
1. phone is not charging at all
2. phone is charging, but at slower rate than it is discharging
1 you can test by noting battery level, shutting it down and let it charge for an hour or two, or even overnight. USB 2 should give you about 400-450 mA, battery has capacity of 3200 mA, so figure in about 8 hrs your batt.should charge from 0% to 100%. or about 10% -15% an hour.
2 you can test by watching how much discharge you have overnight: I normally have 3% -5% discharge over 7-8 hrs night, when phone is not used, but on.
If your phone discharges more than 20-30% overnight, then it will take forever to fully charge and at above about 70% discharge, it will never charge fully, since discharge rate is similar to charge rate. If that was the case you need to find what is responsible for such high discharge rate. As somebody else already mentioned if you're using phone while charging, the screen alone will take as much power as the charge can deliver, so in that case the best you can hope for is slower discharge.

My case is 2. phone is charging, but at slower rate than it is discharging, AND only on USB, on energy socket is totally normal...
I don't know, i wish my phone is indexing, coz yesterday I put tons of pdf, photos, musics and videos, but why it taking so long to index, is it normal?
My problem is so serious that if I put the phone on usb and let it away sleeping, even like that the phone slowly descharges.
Well, maybe this is the answer : http://forum.xda-developers.com/showthread.php?t=2461958
I will wait little longer to see if its continue indexing.
Sorry can''t help much with indexing, it's the first service I shutdown on all my computers and phone as well, I would imagine you have to wait it out until it's finish or root and shut it down, I don't know about you, but I very rarely search my own files, to the point it's not worth it even if the impact of indexing was miniscule. In the meantime can you force shut it down at least when not charging from outlet? Possibly it will restart, even before next boot, but maybe long enough for phone to charge.
Well i fix my problem. But I'm not satisfied.
Wat you need to do is ERASE all your PDF data. PDF files has a king of a problem with indexing on note 3.
Of course if you have a rooted device, you will have more options.
I'm not satisfied because i can't have my pdf classes on my phone, where i like to study. At least all in once.
TY FOR ALL THE CONTRIBUTION.
I think you give up too fast, you bought expensive phone, why not use it to it's full potential? One option would be to root and freeze indexing like I did. I'm not sure if that would disable searching for words all together or just slow it down, but I think that's better than nothing. Another option which I just thought of now, kind of crazy idea, but maybe it would work, rename file extension, instead of file.pdf use something like file.123 or maybe even file extension that should not be indexed like .jpg or .png. Hopefully indexer will not read file header and just skip it. When you need to read it just force open with some pdf reader, no idea if it will work but try. Another way, maybe it won't index compressed files like zip and again I don't use it so don't know how it would work in real life, but just couple ideas to try.
