There were some threads and posts on this before, but it seems like no one really knows for sure.
Are there any risks in charging your phone in android, especially for long periods of time? Some people were saying that there may be some driver/kernal issues which might cause an overchage the battery.
Anyone know anything about this?

I thought the fear was that it caused data corruption of the android install?
Either way I have had no tproblems so far (Original battery)... the back of the device warms up slightly during charging and then coold down when 'complete'.
Now with mattc 1.6b, even the green 'charge complete' LED is working...even though it did turn green at 99% lol.
But it never use to turn green at all for me.
Either way, so far Ive had zero problems that I can attribute to charging while android is running.
same here , i do sometimes whenever i do sleep , let my phone charge
in winmo , but i never had issues with charging in android
I have had no problems what so ever either, and I have been charging it in Android for the last 3 weeks or so

the latest zimages really fixed all battery charging issues , iam getting the green light and the battery reaches 100%
The latest shubcraft build works well for me. Earlier builds would stop charging at 93% but now goes to 100%. It seems like the more recent builds charge more quickly as well.

Ditto, as of the 8/24 zimage.
Just to add to the posts here, I have been charging in Android since I first put in on, each night I plug it up and unplug in the morning. I havent noticed any degradation of the battery or any other ill affects.
Think you might have confused a HTC with a Nokia..

sick I know
I charge in Android and it works well. I need to solve the battery drain issue when I am a heavy user of it.
So i'm retiring my G1 today and picking up an HD2 tonight. I have done alot of reading about android on Hd2 and that the battery life performance isn't that hot yet. But nobody really specifies the range of battery life. i know it depends on use, but with moderate usage am i expecting to get 3 hours of like or like 12? i also know it will vary from rom to rom, but which one so far by user experience seems to be most stable? thanks for your help guys.

With heavy use I will make almost 3/4's of the day, and if with just light use i will get about a day and a half out of it. Im using darkstone froyo v3.1 w/sense
I cant really say if its the most stable because the only other one i have used is a MIUI which is pretty cool just doesnt havnt have facebook sync. the froyostone sense build I use is awesome, I get no black sod's or screen freezes, wifi, gps, 3g, music player, and youtube all work perfectly. I havnt had to boot back into winmo in 2 weeks now, and that was only because I had to inorder to upgrade froyostone from v2 to v3.1
I had incredible problems with battery life with the stock TMOUS HD2 SD card. After swapping to class 4 8gb sd, it's been very good, ranging from 3-7mA standby lasting about 24 hours or more on a charge. It's current 3:14 where I am, I took my phone off charge @ 7:00 this morning and I currently have 59% charge left. There's some sort of bug with android where I can only charge to 96% (maybe my battery isn't calibrated??). I digress.
Things to note with the HD2:
If you're getting a TMOUS I really heavily recommend replacing the SD card with a decent class 4 one, connect to an SD Card Reader on your computer (DO NOT DO IT THROUGH YOUR PHONE) and format it with 64kb allocation size on a FAT32 file system. That has finally given me a stable platform for Android with decent battery life after weeks of trying. Before this I got absolutely HORRIBLE battery life and stability. But yes, it's worth installing now as a permanent solution.

-If you've done the "full charge in winmo first then in android" tip, it should charge at full. I notice though, when you reach 96% it gets vvveerrrrryyyyy slow but still it gets full charge.
I had that same issue with battery only charging to 92% but after rebooting to windows and charging it to 100% and then reboot back to android I was able to now charge my phone to 100% with android. (see my signature for my build). Hope this helps someone.
I was only getting around 5hrs max battery life with normal usage, calling, texting and internet use. I just installed Setcpu and will play with the settings to see if I could maximize my battery life.
Hey
I have noticed the same charging problem, in winmo it works without any problem but in Android its getting very slow!
Just another question, to maximize battery life I installed SetCPU and set some profiles, like if "Display off - 384 MHz ..."
Nonetheless over night I lost 16% of battery, I dont know why?
Any ideas??
Does SetCPu needs root rights? Are they already included in our builds? (I am not quite sure about that point since I am not able to move applications to SD Card)

How long did you sleep?
Yes, it does, but normally, in each build there is something like a Superuser approval for apps that requires root. But there are events it wont work.
And most of the builds are rooted anyway, I think.
The thing with the App2SD isn't possible on this builds, because Droid runs of the SD I think and your data.img is stored there anyway, so it is on the SD (correct me if I'm wrong)
How did you set the priorities of your profiles in SetCPU? The profile with screen off should have the highest prioritiy.

Disable mobile data, and you would loose about %7 overnight. Disabling 3g is also a good idea.
setcpu needs root rights but all new kernels and builds are already rooted. If setcpu doesnt complain, then it has root. If you are having problems, update your su binary inside superuser app settings.
With NexusHD 1.2 I can get 1% drain per hour, so theoretically, 4 days on standby.
I'd say thats pretty good
Yeah, okay, when its installed on the sd card, thats fine, but I had today the msg that their is not enough memory on the phone, so I thought maybe its nonetheless on the device ...
confusing, I turned off the mobile data connection, i changed just ports, and etc...
Nonetheless I will give APNDroid a go and test it!
I hope the battery will last longer, since I have changed the priority off the single tasks!
I will tell you
I've already wiped battery stats, I think I'm getting full charge, and I'm getting pretty good battery life (over 24 hours last run).
The problem is that Android can't seem to tell the appropriate 0% battery point. Several times I've had the phone shut down when the battery life is at approximately 20%. When I try to reboot, there is not enough juice left to make it even to the multi-boot loader.
Is there a way to recalibrate the dead battery point so Android reads correctly?
BTW, I'm running Darkstone SuperRAM Froyo 1.5. (SD/RAM build)

have you tried turning off the phone and let it charge to 100%(when you dee the green notifiationled) and then turning it on. and then wipe the battstat.
just an idea, always used this method if the phone cant charge past 99%, maybe it wil work to on the dead point.

Yes, that's how I wiped the batt stats the first time, which greatly improved battery life. But now there is the power off at 20% thing. Strange.

Then its the roms fault some things are just the way they are. Mine goes to 15% and shuts down. The build I'm now using goes to 8-7% with 100% charge. What Rom u using?

Oeps, you're running syperram I see I had that same problem with superram. I just live with it try nand roms!
Sent from my HTC HD2 using XDA App
i think it's the build's fault. me and a fellow xda user also experienced the same thing with superram.
Thanks for your help! Guess I can stop searching in vain for a fix. I love the build otherwise - the only one that hasn't given me sleep of death with TMOUS.
Unfortunately I can't go NAND yet due to a crappy WM application I need to use for work, which isn't available in android.
See if "Tasker" app can do an auto shutdown at 20% and keep a spare battery in the pocket if you like SuperRam. I like SuperRam and it's my build of choice. Not a fix, but a spare battery in the pocket is good anyways.
currently, my Atrix always could not charge battery fully even using electric outlet. is there anybody know how to fix it.
You could try calibrating it.
Charge the phone until it no longer charges. Leaving it plugged in, shut the phone off, then pull the battery. Wait for it to boot up and display a ? and battery symbol. Then place the battery back in. It should read 5%. Leave it for a few seconds, then boot the phone. Should now read 100%.
definitely trying that later today, thanks.

This, but I would add, that when you reboot, go to recovery first and wipe battery stats.
Mine has the same problem. Never charges past 60%. Calibrating, wiping battery stats several times does not fix it. I plan to buy a new battery to see if that solves it but I am not optimistic. Search for the thread named "atrix not charging past 88%", no fix for me yet and several others.
re install rom and full wipe
Don't forget to flash the juggernaut battery fix too

Same issue here, the percentage isn't always the same though. One morning it will be 94, 96 the next, and 90 the next. Always at 4207mv at those points. Tried wiping batterystats full, empty, etc.

I thought this was already part of most roms out now?
Juggernauts fix helps the battery jumping issue, but not the battery not charging to 100%, at least not for me. The problem started after flashing official 4.5.91 and it has continued after I flashed to CM7. I am now used to removing the battery and putting it back in place while charging for it to read 100%, but it is annoying no one has found a cause or solution.
It really works
thanks

Let us know if it is fixed after a full battery cycle. Mine goes back to its old behaviour after one or two cycles.
Hi everybody
It may be a noob question, but i've wondered if it's actually necessary to charge the device to 100% before flashing a new rom. I've flashed many roms, but I always waited untill it was fully charged. Back in the days when I had my galaxy S, I've read that you should charge it to 100% before flashing a new rom or else the battery would be calibrated badly.
I know it surely doesn't harm the device to fully charge it but it's a pain in the a** if you do it everytime you try out a new rom.
So is it still necessary to charge the device fully before flashing a new ROM?
Thanks for answering

in my years of flashing, i dont think that ive ever flashed when i was at 100%, and ive never heard of the need to be at 100%. id never be able to flash on the spot. oppositely, i know ive flashed countless amount of times while under 10%.

You don't need to be fully charged each to flash. Just make sure it's above at least 50-60 percent of power left just to be safe.

You don't have to charge it to 100% AFAIK. Just make sure it'll survive the flash (don't flash if you have less than 30% battery left) and charge it to 100% when you've booted after flashing. That's what I do and it works just fine for me.
Thanks for the answers, feel kinda silly now that i've always waited till full charge

Ive flashed with 15% power before. Makes no difference. In all my times of flashing ROMS and kernels ect, ive noticed it usually takes about 1 to 5 % max batt life to backup / wipe / flash.
