i agree that the hardware shoul have an autocut off as has been the case for decades but what we dont know is what effect the battery controler not being in control has over this, i think personally your right, it wont frag your battery but i cant be 100% sure, no one can, as i said, if you keep overcharging a battery it will reverse its polarity, hard to tell this except for the fact that it wont last as long as it used to
[HD2 Windows Phone 7 Development] Gustopher:
Moving away from the philosophical realm into the more practical, I gave this method a go and can report NO significant difference in my case.
[HD2 Windows Phone 7 Development] ndamianou:
I am sorry but this is not true. At least not for everyone. When your phone dies and shuts down because there is no more battery then you know that it is not just the reporting of battery life that is wrong.
[HD2 Windows Phone 7 Development] Inneandar:
I did a similar thing before, charging the phone when it was switched off - I didn't go into MAGLDR, just hooked it up when switched off, the orange light goes out after a while but the phone acutally keeps charging (you might have to take out the battery to get it booting again) - and also couldn't really see an improvement in battery life.

My average battery life sucks, by the way, with the phone lasting barely through the day on a charge (average use, data always on - 2 push mail accounts)
[HD2 Windows Phone 7 Development] :
:cool: cool to see battery ideas and all but......Overheating is a more serious problem! :(
[HD2 Windows Phone 7 Development] vista1984:
thanks, but i prefer charging in android because i need my phone to be alarm clock
[HD2 Windows Phone 7 Development] Alcatrazx:
At present there is NO FIX as far as 1.13 is concerned. And to all those who posted the Android / External charger alternative. If you read the original post you would know that these are exsiting things which people tried with success. I however got more longevity out of the battery using this method. I got 40 hours for sure out of it which to me is a record with regular usage including wifi ...
[HD2 Windows Phone 7 Development] Alcatrazx:
not the case re overheating
[HD2 Windows Phone 7 Development] Alcatrazx:
I never got the mobile to charge while the battery was off. The mobile HANGS when you do so with every version of MAGLDR ... try the alternative, it worked for me ... then again its a free country ..
[HD2 Windows Phone 7 Development] Alcatrazx:
How long did you charge it?
[HD2 Windows Phone 7 Development] kdskds:
Is it a different between loading the batterie in Boot-Loader-Mode and when the phone is turned off??

[HD2 Windows Phone 7 Development] abq1230:
carefull overcharging

yeah that's sounds really logical but with my experience with electricity, 6 hours of charging is a lot, too much, for that kind of batteries. It would damage your battery in a few days.

I recommend direct charging any 3.7v li-ion battery up to 100 minutes with a 1200mah charger.

It's up to you.
[HD2 Windows Phone 7 Development] Alcatrazx:
I never charge the battery for two hours. Simply because the mobile is NOT off but on. I never got the led to go green after 2 hours. So its draining the battery while charging. Typically if phone is on and charging it will take much longer than that to charge. The 2 hour mark is valid only if you pull out the battery and charge it in cradle charge. Then again even the TYTN II (Which I opened up and checked myself) has a built in cut off circuit which still goes on (irrispective of how long you charge it),so it won't damage your battery. The only advantage of this method is that the "software control" of windows phone 7 will not be working and will not stop charging your battery "prematurely" and for the record this IS harmful to the battery . I am sure that this will be fixed later. If nothing this method is helpful if you are outside and you do not have an external charger. I had to pull out 2 wires off USB to charge the battery when I had incidentally drained tbe battery completely, no need to pull out batteries and carry useless gadgets with you ..this solves that issue.

If nothing, you can do this if you prefer, Charge the mobile "completely" in WP7 with WP7 on ... and then go into bootloader for an additional hour or so. ... With original method (WP7), I pullied out the battery it was not fully charged (roughly 64-67%) with digital meter, with bootloader, you get it to charge fully (checked again). Android also reported it was full of course.
[HD2 Windows Phone 7 Development] Alcatrazx:
I don't know you but ... i for one never got the phone to charge when it is off.... if you got it to charge when it was off,

- you surely are lucky man

- the phone hangs when you do so

- You always have to pull out the battery to restart it, I hate that.

And yes it is exactly the same effect i.e. HTC circuitry would be working only.
[HD2 Windows Phone 7 Development] Alcatrazx:
you actually get to charge it to its full capacity.
[HD2 Windows Phone 7 Development] wtf666:
The most draining thing in WP7 is the mobile connection. I get <12h with mobile connection on and 2days+ with mobile connection off, with moderate usage. I only turn it on, if I need it.
[HD2 Windows Phone 7 Development] dazza9075:
let me get his straight, you turn the mobile connection of your mobile phone off?

i assume you mean the data connection?
[HD2 Windows Phone 7 Development] bigarm:
If you recharge in malgar mode then apply the reg fixes first to 20 then to 80 and reset your device and charge again it seems to work fine 35 hrs now and still half charge left.
[HD2 Windows Phone 7 Development] Gustopher:
3-4 hours. I was worried about damage to the battery if I charged longer. I have only tried it once, which is hardly scientific, but it made no discernible difference whatsoever - in my case.
[HD2 Windows Phone 7 Development] exitmood:
Going to test.. I will try and report :)
[HD2 Windows Phone 7 Development] Alcatrazx:
The problem with the reg fix is that it is not a permanent fix. I have looked into it myself. You are just changing the values monitoring the charge but you are not changing the underlying code producing those results. After reboot those settings are lost . . .

As for my settings I will post them here once more:

I use:

WIFI when needed

LOCATION off

DATA OFF

3g OFF but when ON seemed to make no difference

I changed screen timeout to 30 seconds

Turned off email updating and I turned it to manual

And brightness is set to auto

I use MGLDR 1.13 and Radio 2.15

Any other questions please feel free to ask.

I never ran into battery issues when charging in USB mass storage mode. IF nothing, if you happen to be abroad and you have no cradle charger you can still use this method to get your phone up and running again without the need of having Android on SD.

The best I got so far is 42 hours. But did not seem to go past that mark.

Any other fixes within this forum, I have tried and the only viable ones to make the battery charge to its fullest is by NOT having windows phone 7 running while charging the mobile.

Al

[HD2 Windows Phone 7 Development] ricsonrainer:
Overcharging myth

This is my opinion and my understanding about overcharging issues and charger designs.

1. The cradle charger connects to the 2 terminals of the battery to charge it. It has an electronic way to compare voltage supplied to the battery and what the battery has (in real-time). Thus, it cuts the circuit when the battery is the same level with the regulated voltage supplied to it... connects the circuit again when the level is less than required. This is done electronically.

2. The wall charger (that connects directly to phone) also has the same electronic design like the cradle charger. That means, if the phone can charge while it is "off", it will charge the battery following the same concept like the cradle charger. In addition, electronically, the phone also has the same electronic design to cut-off the charging circuit when the battery is full using the same concept again.

3. Now, when the software (Android, WP7, etc.) are running, they are monitoring the battery power using the third contact from the battery. At this point, the software tells the circuit to cut-off or continue whatever the software wants to do. So if the software is not doing its job, then the battery will be undercharged but will never be overcharged.

In summary,

1. The wall charger protects overcharging the battery.

2. The phone protects the battery from overcharging.

3. The software (if running) regulates the charging of the battery.

Have a nice day... :D

Hey folks,

I am really interested in following your discussion(s) about the WP7 Battery problem...

Unfortunately I just can not charge my HD2 while it is turned off! Everytime I try this, the phone automatically starts by itself, its booting wp7 :(

So I wanted to give this advice a chance and now have the following problem:

Do I have to charge the phone in "USB Mass Storage Mode" or in "USB-Flasher Mode" ?

Thanks for help :)
[HD2 Windows Phone 7 Development] Alcatrazx:
Which is why I originally said that there is no harm being done to the battery in either case... unless some crazy user decides to charge the battery directly with 2 wires from usb .... that is :) There is something wrong with the "override" in WP7 mode that's all... I pulled out the battery to check how "full" it was when charged with WP7 on ... it never goes beyond 65%. The only way I got it to charge completley is by using 1 ... or 2 as you proposed or in Android or in USB mass Storage mode ....

Have a nice day :)
[HD2 Windows Phone 7 Development] Alcatrazx:
I was very clear in the how to ... It was also very clear that we mentioned that in

- MG LDR 1.12 hangs when mobile is off and you are attempting to charge it

- MG LDR 1.13 has been quick-fixed to restart mobile when you hook up USB when it is off and you try charging it

I suggest USB mass Storage mode because:

1. You can hit the back button and go back to the main menu ... reset mobile and reboot

2. In flasher mode you don't get the same effect really ... however you would have to pull out the battery in order to reboot....

Please read first post for full details. Glad you're following :)
[HD2 Windows Phone 7 Development] T-Macgnolia:
I read some of this thread not all though. I also posted this in the thread that lead me to this thread. There is something that I think the OP of this thread and a whole lot of people using MAGLDR do not understand. I qoute this straight from the OP of the MAGLDR thread.

You have to have a functional OS installed for you to even be able to charge your battery using your HD2 when you have MAGLDR installed on your HD2. The simple fact that the OP of that thred has a WP7 ROM installed on their HD2 is the only reason option #4 USB Mass Stg even will slightly charge the battery, if it was no ROM on the phone, just MAGLDR, it will not charge at all just as when you are in bootloader and the USB connected it will not charge no matter if you have a ROM on the phone or not. I personally think the slight charge you get by using option #4 USB Mass Stg in MAGLDR is purely accidental and only a small amount of voltage as it takes so long to get any kind of substantial charge. Also if you have a completly dead battery you can not even boot into MAGLDR to try to charge using opyion #4 of MAGLDR.

I am a electrician and have been for a little over 15 years and in my oppinion if you have a dead battery and you are running Android from NAND or a WP7 ROM using MAGLDR. Your best bet is to use.

A: A external charging cradle.

B: Another HD2 that is running Win Mo.

C: Using a modified USB cable to get enough charge to boot into your ROM

Note: The last option I listed is only in a emergency situation as I do not advice you use this as a everyday charging technic. Also only long enough to boot your phone so you can finish charging normally. If you do use this option maintain a constant watch of the battery to insure it does not start to become warm, and only use your wall charger when using this method. The voltage is very low that the wall charger sends though the witres so there is no danger of shock.
[HD2 Windows Phone 7 Development] kushki:
has anybody tried the HTC battery tool... I ahd battery probs and than I installed this XAP which just set the values right for full charge and no charge, after that every time I charged my phone it charged full 100% and I had a good battery life of 24-28 hrs with a decent use (way better than android). give it a shot and see if it works.

[HD2 Windows Phone 7 Development] Alcatrazx:
ok so...

I'm glad to know that you are an electrician and you have been so a long time ... but everyone in this forum appreciates facts to speculation ... what you personally think ... and what is the actual fact are two different things

Here is why...

RE the completely dead battery .. you are 100% wrong for one simple reason ... even with a completely dead battery ... you will get to MGLDR menu if you have the charger plugged in ....and yes ... I have ran into a drained battery problem 100's of times ...

RE be it purely accidental or not that MGLDR charges the battery or not I don't care ... what I care about is that it WORKS..and as I told you above everyone prefers facts instead of opinions ...

Regarding the longer time to charge .. it's because the phone is on ... had it been off it would charge in half the time...

I tried what you said without the OS ... and I can reconfirm you wrong as the phone still charged the battery.. the phone in HSPL mode or FLASHER mode will not charge the battery... why? Because while flashing, the hardware is not active and that is precisely why everyone over here is advised to have at least 50% charge before flashing his/her mobile....USB mass storage is a totally different thing ... has nothing to do with FLASHER mode ...

If anything this fix helps all those who do not have access to A, B , C which you have mentioned, they still get to work .... but I 'm not too sure that you read this ...
[HD2 Windows Phone 7 Development] Alcatrazx:
I don't know you but with what was originally suggested, the mobile is giving definitely more than 40 hrs with good usage and I only go in boot menu when battery is completley dead ... the rest is charged as soon as I boot into winpho7 ... While I did not take a go at the program you mentioned, I will most certainly take a peek...

[HD2 Windows Phone 7 Development] Alcatrazx:
Apparently it seems that we are close to another DFT release so hopefully the whole battery charging issue will be solved once and for all... I foresee that are nice things coming up for our lovely HD2 :)
[HD2 Windows Phone 7 Development] Alcatrazx:
It's a free country ... say what you want ... believe what you want the only thing I agreed with you in the post is that I am trying to help people out which is a fact ... I don't know how much you read from my original post or from my reply to you ... but lets stop this discussion here ... A dead battery means that you cannot get to the OS ... Not even past the DFT screen if you know what I mean ... ok granted , you would still have some milliAmps left in the battery ... but then again the OS is not "on standby" when you enter the boot loader ... nothing would have loaded as yet other than the MGLDR itself ... when you go into mass storage mode ... and I don't think that it's a mistake either that Cotulla ensured that charge is provided to the device when using the HD2 as a USB drive ...for obvious reasons really ... Imagine putting large amounts of data on your 32GB card ... and you don't really want your mobile to die in the middle of a data transfer would you?

The hardware would indeed be activated in HSPL ... otherwise the Device Centre would not be capable of tethering with the device ... and the device would not repond with a "USB message" on the tricolor screen .. obviously while transferring data during flashing and the device is being flashed clearly most of the hardware would be off (including charging circuit) ... which leads us to why the battery has to have sufficient charge before flashing ....Anyways I was clear when I said to use the usb mass storage mode for charging ..

No matter how much you charge the battery, it has a built in cut off .. If you put a CRADLE charger apart (which I did), you will notice that it contains no circuitry for cutting off the voltage going into the battery ..

If anything if you dont have a cradle charger around ... and you're abroad .. like I was .... how will you charge your device just equipped with a USB cable? YOU WONT manage to boot it to the OS if its overly discharged ... I cant seem to stress this point enough ... This is NOT about charging the device ... it is about getting yourself out of trouble quickly .... when short of resources....

You can always get your device "slightly charged" in boot loader (usb mass storage mode) ....for say 5 minutes (definitely no harm done) and then move on into the OS to proceed charging the device correctly.... It worked for me and should work for everyone ... battery life or damaged battery? Not a chance! With the proposed settings and Radio 2.15 ... I am getting ample battery life now ... 40-48 hrs + and am not even charging in Boot loader anymore .... I dont even have to!

Thanks for making your point clear.

Once batttery is dead I can not reach MAGLDR at all. With or without phone plugged in outlet. So he is not wrong.
[HD2 Windows Phone 7 Development] hjhjhj:
There is not difference between charging the phone in whatever mode! And why is there even a question on this? Regardless of which mode you use, your phone is still on, so why not be able to receive calls?

What is the problem? That your phone turns on automatically to charge when the charge cable is plugged in? What is the point of this whole thread? Debating the electrical properties of dead batteries?

Go buy a secondary battery and an stand-alone battery charger. That way you can turn your phone off and have a fully charged battery in the morning or whenever to pop into the phone. Geez Louise...on and on about a dead battery and what one is able to do or not do.

Folks....this whole thread is moot! And for the guy who said he's getting 40hrs on a single charge for a HD2. What a piece of crock!!! Even without using the HD2, the battery will be dead in 2 days tops whether WM or WP7.
[HD2 Windows Phone 7 Development] zcdg:
It is not true.
[HD2 Windows Phone 7 Development] samson291:
Codswallop! I for one have gotten 3 days on android with my HD2.
[HD2 Windows Phone 7 Development] dazza9075:
Ignore him, he seems to be doing just about everything he can to piss people off lately

anyhow, to your question, the issue resides in MAGLDR, it can not control the battery as such, so its setup to automatically turn on the phone as soon as DC power is supplied. at least it was with 1.12. The HD2 with MAGLDR can not charge in an off state however, you can charge it in MAGLDR mode which will obviously charge it, but because the screen wont turn off, its a bit of a waste, id only use that method if you are having charging issues. some times in WP7 it wont except a charge at all, so boot to MAGLDR, plug it in and usually it will fill you up.kist dont leave it too long :) oh and the wee orange light wont come on

A couple of reasons i'd have for wanting to do this is, first and foremost, charging a phone in its off state charges significantly quicker, secondly, again for my self, why waste power? having the phone on when your not wanting it wastes power, so turn it off, charge it up, it will reduce to trickle charge when its full and all is good in the world.

[Defy Android Development] kjozsa:
I've brought my sdcard from my old HTC Magic. There (using cyanogenmod) it was partitioned to have swap, ext4 space for apps2sd and storage space as vfat. I did not repartitioned the card since I started using my Defy but it ran out of space already.

The question is - do I need swap and apps space or shall I repartition my card to have only storage space for the defy? I'm using Jboogies rom, if that matters.
[Defy Android Development] naenee:
You do not have to partition your MicroSD card at all.
[Defy Android Development] ABC_Universal:
Shouldn't need apps2sd or space in sd card for applications. Defy has over 1g available rom space out of factory.

Can you guys help me with some problems please? I`m new with this phone i have 2 days, my old phone was with android too but with this one some things are different. So, i really need to know:

- to update to 2.2.* i need to be with 2.51.1 of i can flash over 2.34.1?

- what is the original recovery and boot for 2.34.1?

- with defy_recovery-1218-0326-signed.apk i can make backup to original 2.34.1?

- if in case i need warranty i can flash the original recovery?

[Desire HD Q&A, Help & Troubleshooting] dansharpy:
Hi,

I rooted my DHD and flashed Revolution HD (2.1) ROM yesterday for the first time!! This site helped massively so thanks to all the devs and posters for the information!! I do have a couple of questions though, please excuse me if these are a bit obvious but until yesterday i had no idea how to even root it!

So i flashed the ROM and rooted fine, then i flashed a custom theme as well from clockwork mod recovery (installed from zip on sdcard). If i want to change the theme to a different custom one do i have to flash it from CWM recovery or can i do it directly from the CWM app??

Also if i now flash a different custom theme will all my user data (apps, settings, media etc.) be preserved?

Basically i like to change my theme quite often but if im going to loose my data everytime then ill have to pick more carefully!

Thanks in advance for your help and thanks again to all the devs and posters for making my DHD even better!! :)
