Battery Charging: Is it workin for you?
 

If your battery is charging, please list the carrier you use, the rom you use, wether you plug into a wall or a USB, wether or not you changed backlight settings to run android with suspend, and anything else relevent to the situation.

Some people claim that Android charging does not work, some say it does. Personally, I would always unplug not even thinking that my battery might have been taking the charge. One day, I opened up the battery monitor and payed attention. Using the battery meter over a course of maybe 15 mins or so with a charge source plugged in, does you battery level increase? If so, post the hardware/software conditions here so we can see if this is something others that need it may be able to obtain.

To see this screen, open battery monitor to be sure the upper left corner of your screen says 100, then slide the top taskbar down to reveal the moitor. Possibly the developers can use this info... and pos it's just useless, but Here is mine.

Note that this is a reference. Your best bet is to open the battery monitor, check your battery boltage and then put the phone down for 10 minutes. If you have a phone capable of charging, battery voltage should have increased after 10 minutes... rather than decrease. Those reporting charging capability also seem to have the graphic of a plugged in device showing "fully charged" on the phone when it is charging.

Please do not ask "WHY" your phone won't charge. Nobody knows the tie yet. That is the purpose of this thread. Some do and some don't. That's just the way it is right now. Thanks

Re: Battery Charging: Is it workin for you?
 

I find it interesting to note that the temperature that it is registering is in F already, but that the monitor tool is reading it as C - 177 F is about 80 C, and 80 F is about the right temp the battery should be running at.

Have you poked around the market for any other battery monitors? Anything that might display mA in/out?

Re: Battery Charging: Is it workin for you?
 

I agree with the above post. Yeah my guess is that andriod see the battery as way to hot and won't charge. 177F is crazy hot and would be close to causing a Lithium ion battery fire.

Re: Battery Charging: Is it workin for you?
 

I was using sprint stock 6.1 rom with xdandroid 01.03.10 and kernel Build: htc-msm-android@20100318_061343

I could charge using usb to my lappy, but only if I had plugged in the phone before booting to android.

I tested this by looking at the power bars in wm... I had 6 green bars, booted to android, messed w/ it for 10 minutes, then set it down (asleep or "off"), left if for an hour or so, came back and played w/ android for another 10 minutes, restated into WM and had 8 bars....

Re: Battery Charging: Is it workin for you?
 

Mine was working, but ever since the new kernal i am not having as much luck. it was at 85 right before booting to android yesterday and I plugged it in for about 3 hours to my pc via usb, came back and reset it and it was up to 100%.. Verizon energy rom with Mackies xandroid and new 03/19/2010 kernal

Re: Battery Charging: Is it workin for you?
 

Wait. I never really noticed that. I can see that alone as a battery overcharge protection. If it sees the battery is too hot I am sure it will stop charging.

Re: Battery Charging: Is it workin for you?
 

New Sprint Stock 6.5 ROM, unmodified, in other words didn't adjust auto-dim yet.
Of course plugged in activesync before booting. And it charged. Testing with auto-dim enabled next.

Mightyrom 2.1, did adjust the auto-dim, and it would not charge. Did not test with auto-dim enabled.

Re: Battery Charging: Is it workin for you?
 

Update #2, I tried with Auto-dim disabled and it still charged, so it is a confirmation that the Sprint Rom seems to work. Something in Mightyrom 2.1 doesn't.

Again though, I can't stress this enough, I wouldn't leave your device charging this way for an extended period of time, like overnight for instance. Being as the charging code hasn't been completed I don't know for sure it shuts off charging when full, and would hate to see lots of you with blown up phones.

So we just need to gather what roms are working and what aren't and determine what is in them to allow the charging. Till a charging circuit can be made.

Re: Battery Charging: Is it workin for you?
 

I am using EnergyRom with a Verizon Rhodium(Rhod500). It was not charging when I had it plug into the computer with the "Disk Drive" selected for the usb option in windows mobile. When I switched to Active Sync and had it plugged in while staring Haret, it is now charging. I was able to unplug and replug it back in, even then into the wall charger. I was able to leave my phone in Android all nigh and I just rebooted into WM and I had had 100% charge. Give it a try to have an Active Sync USB connection (not Disk Drive or any other option) and let it boot into Haret. Should try to install a "smartphone" driver but mine always fails. However it will charge through the computer USB or the wall charger.

Edit: I just read the previous post about if the phone stops charging when the battery is full. I charged it over night and when I woke up, the phone was not hot at all. This to me seems to indicated that it did stop charging once it hit 100. However, I am not promising that it will. :-P

Re: Battery Charging: Is it workin for you?
 

Heh, ya hopefully that is a sign that it is stopping, but I just would be careful depending on that. It does seem to carry lots over from the WM Settings, so due to that maybe it knows to stop, but I just wouldn't trust it. Be careful, but that is great bud!

Re: Battery Charging: Is it workin for you?
 

Yea, I was also wondering if there might be a hardware cut off that prevents the battery from over charging. I know some/most electronic devices have devices that prevent this. However, I do agree it is probably not the best choice. Have you gotten your battery to charge?

i am using Sprint tp2 with mighty 2.1 rom and for the life of me cant seem to get android to charge. I have updated several kernel and zImage and now on the wireless tether rootfs,zImage, and module still not charging.

plugged in before boot haret with auto summing off. No go.

plugged in before boot haret with auto dimming on. No go.

USB plugged in with disk drive option with both auto dimming on and off. No go.

USB plugged in with active sync option with both auto dimming on and off. No go.

So thats my current charging situation.

Re: Battery Charging: Is it workin for you?
 

I found something interesting as i have been playing with my cell. I have had a lot of issues with my phone booting into Airplane mode very randomly and decided this was probably something to do with it wanting to use GSM over the cdma radio. I removed the sim card, started up WM (I use Mr. X Rom from 3/5/10) with the charger unplugged and auto dim off (not sure if auto dim makes a difference for charging or not yet) i booted up HaRet. I no longer am having issues with Airplane mode after a few boots AND charging IS working!!! If i unplug the charger is says "Li-ion Battery Not Charging" and when i plug it in it says "Li-ion Battery Fully Charged". I also noticed the voltage go up to 4.716 from the unplugged 4.698". From what i can see it is charging and it is stopping when it is full. I will need to wear down my battery to really check it to make sure but all seems to be working in that respect. I am on the latest daily build on android - 3/19/10. Let me know your findings and if anybody else see's the same thing i am seeing. Ditch the SIM!!!

If anyone wants to know more info about my setup let me know. I think i have mentioned all of the needed info to get it working though :)

Edit: Sorry, i am on a RHOD400 with sprint in 3G coverage area in IL
Edit 2: This seems to be working with both the USB charger and wall charger.

Re: Battery Charging: Is it workin for you?
 

Correct. At this point this Android build requires you to remove the sim. With out this it thinks that your phone is a GSM phone and gets all confused. With no SIM it boots as CDMA and works perfectly with 3g data, SMS, calls, etc.

Re: Battery Charging: Is it workin for you?
 

When i read through the FAQ's and everything it did not say anything about having to remove the SIM card and the Android forums are getting way to long to keep up with anymore so if that was mentioned before i am sorry. The question is now though, since yours is charging without the sim card in also. Is this what puts us in the same boat and others just have not taken their sim card out because they did not know like i do now?

Re: Battery Charging: Is it workin for you?
 

No I'm not mad. I'm just confirming that that is the way that it is supposed to be. Check your Private Messages.

Re: Battery Charging: Is it workin for you?
 

I didn't mean sorry as in i thought you were being mean. I meant sorry if it was already posted somewhere in the forums about having to remove the sim card. I am still very curious if that is what ties it all together since i couldn't get it to charge prior to removing the sim card :)

Edit - Okay, it does say it in the FAQ section now. When i loaded up android a few days ago it was not there. I am really surprised as to how quiet it is on the android section. I would think this would have more momentum. Maybe i need to stop over at xda.

can u confirm that it really is charging ? I'm on sprint tp2 with mighty 2.1 rom and it did exactly the same thing as you just described but when i boot back to windows, my battery level is actually less than before i boot into android.

Re: Battery Charging: Is it workin for you?
 

I am actually letting the battery discharge right now to about 20% then i will hop back into android and start the charging process. That will give me confirmation that it is handling it exactly how i think it is.

Re: Battery Charging: Is it workin for you?
 

I'm pretty sure someone said that when they had mightyrom the phone didn't charge, but it seems to on energy. The pics from post one were taken on a phone running energyrom with the sim card out. Glad to see we may be getting somewhere with this.
On a side not, My battery doesn't seem any hotter charging that in winmo, and it's cool the whole time if I have a full battery when I start android. The only time my battery ever really gets hot is when I'm using the internet. That baby can cook an egg no matter what OS I'm running. Still, I agree with the previous post. Since this has not been worked out by the developers, I believe this should not be taken for granted. Use it only if you need it, and don't leave it plugged in all night. I've done it, but I will not be responsible for a mangled charge circuit. That being said, does anyone that has charging use mightyrom? Are you all running with your sim cards out? Report here.

Re: Battery Charging: Is it workin for you?
 

Ya Boomin, I was the one that said that I couldn't get it to go on Mighty's 2.1, haven't tried others, But it is working on the latest Sprint 6.5 Stock. And aside from you mentioning NRG, I think someone mentioned MR. X's rom. So you might add that to your 1st post to narrow down what roms seem to work for whatever reason.

Re: Battery Charging: Is it workin for you?
 

Just an FYI, still on Sprint ROM, but with Captnoord's latest i2c commits, I believe I am charging without being hooked to Activesync before booting to Android. I need more time to do more testing, but I drained my battery to 90% and booted to Android unplugged, plugged in and ran Pandora to try and eat up some battery while plugged in, left it in there for about 30min-1hr and booted back into WM, and it is at 100% now. So maybe those commits fixed it where you don't need Activesync first. Will do more of a drain overnight and plug in tomorrow and see if I get the same results as well as try and get in contact with Captnoord to see if that is by design. I know they were part of it reading the proper Voltage and Amperage. So I am guessing so.

Thought you guys would like to know!

Re: Battery Charging: Is it workin for you?
 

Well that sounds better than what i got. Last night i drained the battery to 50%, booted into android without the charger hooked up or activesync. Plugged in the charger when in android. Left my phone sit for 2 hours. I switched back to WM and it was at 51%... It has to be charging however that is the slowest charge in the world! Either way it i hope cflynt is doing better than i am with the extra info he has gotten. Hope to hear word back soon :)

Re: Battery Charging: Is it workin for you?
 

Thank Boominsvx he is who first discovered anything. So far my only findings are that the latest kernel, with the i2c changes, seems to charge without being plugged into WM first. But so far ONLY seems to be charging via USB cable to PC. I tried it via the Brick, mind you it is a docking stand so it might be different than like a stock charger etc. But it didn't charge at all then. I am still trying different things. And mind you it is still being worked on by the devs, just one commit that seems to make the change from needing to be Activesynced first. And again, I don't know if this latest kernel makes any difference to the ROM you are on or not. Before, even Activesynced, I wasn't charging via Mightyrom 2.1. But once I switched to the new Sprint 6.5 Stock rom it started working, and then the new i2c changes didn't even need to be Activesynced. So there are still lots of fluctuations on what works and what doesn't. Just reporting findings. And again, it is progressing but I still don't think full output so normal charges are going to be varied.

Re: Battery Charging: Is it workin for you?
 

I have tried this multiple times, and it seems to charge each time without needing to be plugged in otherwise. My question is, is anyone still on Mightyrom 2.1? If so, can you update to the latest kernel and see if you can charge now?

Re: Battery Charging: Is it workin for you?
 

I just spoke with captnoord, he doesn't know why the i2c stuff would make the charging stuff work the way it is, but regardless, he did confirm that he wouldn't trust hardware to shut the circuit off when it is full. It very well may, but till more is understood about the chip that controls that, he wouldn't want to risk it. So my warnings stand, I wouldn't risk burning up your device heh. So only charge till you think it would be full, don't leave it on all night. But that is your risk if you want to!

Re: Battery Charging: Is it workin for you?
 

Yes, this is exactly true. Don't trust the hardware to do as it was supposed to, but it's a lot like the accelerator of a car. You can stand on the pedal, but why chance it. Charging doesn't take that long for me, but I've got nothing so far that says anything about it charging faster than windows mobile, so just use it as you must. I'll add the list of possible working roms to the OP. I won't have time to play around with the new kernel tonight, but will test most definately have them tomorrow. So far it seems Mr. X, NRGZ, and Stock Sprint have the capability... more so with the latest kernel. If it won't work for you on the wall charger, don't forget that you can also try usb. When I load android, the driver window pops up asking to locate a driver for "smartphone". I just cancel this window (for those interested). Thanks for the work cflynt. Anyone else besides him have some more factual information?

Re: Battery Charging: Is it workin for you?
 

I noticed that if i plug my phone into my computer it will not go completely to sleep(the light will stay orange). This seems to indicate that there is some connection and it is charging. If i remove it from the connection it will go into the deep sleep with the green LED. Can anybody else who has charging working confirm this seems to indicate charging?

Re: Battery Charging: Is it workin for you?
 

It isn't indicating charging no, but it is showing that it does see a connection to the computer. Current state of the notification LED is for debug purposes only. It doesn't show proper charging/sms/email etc notifications currently. But ya, I guess the phone doesn't completely sleep when plugged in, but if you get it setup to charge then it is doing at least that. I wouldn't go 100% by reading the voltages either, I have been charging while it still shows 4.5 volts. Normally I see it hit up to 4.6-4.7 as Boominsvx has shown in his screenshots, but not always.

Re: Battery Charging: Is it workin for you?
 

Sorry. I wasn't trying to indicate that I thought that the fact that the LED was orange meant that it was charging. I was just stating that it seems to be aware of the fact that there is an external connection and therefore it does not enter sleep. Just seeing if people who can't get charging to work are experiencing the same thing with the LED or not.

Re: Battery Charging: Is it workin for you?
 

Understood, ya funny thing is, and it is rare, but have seen it. I have seen my phone show green while I was charging, this was back when i was doing it via the Activesync method. And it may very well have just been a coincidence. When I was on Mightyrom 2.1, and WASN'T charging, I would still get the orange light. So not sure it has any relevance.
