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.

awesome. I'm running shubcraft 1.4d and the 8/24 zimage, I will be charging regularly in android from now on.

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..

I charge in Android and it works well. I need to solve the battery drain issue when I am a heavy user of it.

Good morning,
I did a search for this topic but didn't find anything which could help so I thought I'd start a new thread and ask you guys.
I have installed the Desire version of Android and it runs fine apart from two issues.
The first is that when the phone is plugged in to either the wall charger or the PC it gets really hot. The heat is coming from the back of the phone but right at the bottom (not from the battery). It got so hot after around twenty minutes last night that I rebooted it into Windows just so I could charge my phone overnight. Windows has no similar issues, by the way.
The second thing is that sometimes the screen becomes unresponsive while running Android. This is mainly on the homescreen and you have to usually turn the screen off (stand-by) and switch it back on again to make it work.
If anyone can offer any solutions to either problem I'd very much appreciate it. If I've left anything out, let me know. It's nearly 7am and I'm barely thinking straight.
Many thanks.
i get the same heat issue whether its plugged in or not(its much worse when its plugged in though). this & the battery life are why i cant run android for more than a couple hours. im sure theyre related too. the heat scares me, i dont want anything to fry out. as soon as i boot back into windows it cools right down. i really hope this issue gets fixed soon.
yeah the problems you have are what some ppl have and to my knowledege they have not been fully solved yet. But its still a work in progress, just give it some time
I can deal with the overheating I turn the screen off for a while and its good.
What I can't deal with is THE CONSTANT FREEZING!
It's really starting to piss me off!!
I think its because of the class 4 SD card, I'll get a class 6 SD some time this month and I think that should help out A LOT!
i 100% using external charger with few batteries, so i've never realize the problem.
find a good task manager app from the marketplace and kill all apps that are running in the background. that cooled down the device quite a bit for me
i don't think so

i don't think so. mine is 8GB class 4.
I think it may be related to your radio and rom.
I am on claudyfa's 1.5 rom and 2.12.xx radio - you can give it a try
If I use a lot of apps in android, it gets really hot, like in win mo. but android is hotter
good luck
It's freakin beta. Secondly use set CPU and lower your clock speed. It save battery life also. As far as the freezing its a result of the beta nature of the roms

I got the same problem with MdJ Froyo HD 4.4
Is it a known issue now ? Can it be solved by anything ?
PS : Sorry if my message is not very understandable but I don't really speak english ^^
I remember that someboy have already said it, but i've not found on the forum a solution.
disconnecting the charger means an immediately pass from 100% to 99%.
why this bug?
how can we solve it?
thanks
Hmmm i think you must connect charger

This seems to be a much more common behaviour since 2.2.1 ROMs came out.
However a pattern is still to be extracted from this: for example, when i charge the phone while powered off, and then boot it, once boot is completed i was able to see 100% for 1-2 minutes even after finally unplugging the charger.

One guess is that Samsung changed "the mathematics of charging" the phone, at least while charging with phone on, and may have done something wrong with displayed charging levels, but not necessarily with battery life itself.
Another guess is that your "2.2-calibrated" battery is somehow different/seen differently from a proper "2.2.1-calibrated" battery. Could be a matter of recalibration, or a combination with the previous point.

At the moment is unknown.
This issue, and many others related to battery, it's currently being analyzed much more deeply in this thread.
For example, a user has just found out that 3rd party applications like Juice Plotter properly recognise 100% level even after unplugging the charger. This is interesting.
So it's still a work in progress.
It's just displaying it different. Battery meters are not accurate, that's just the way it is.
If the charger really kept your battery at 100% while it was on the charger then your battery would wear out very quickly. In reality it allows it to drop to around 90% after hitting 100%. The battery meter just stays at 100% for a bit on most phones so clueless users don't think something is wrong and wear their battery down by repeatedly forcing it to 100%.
Stop worrying over little 1 or 2% differences in battery readings, they are nowhere near accurate enough to judge such small differences.
It is interesting though, that this problem doesn't occur to me. I'm on JPY based Darky's rom v7, and the battery is reported as 100% for I don't know how long, after plugging in. I could confirm exactly how long but atm I'm testing to see how many days I can push out of the battery
Also, it doesn't seem like a problem to me. I think that maybe Samsung altered the algorithm for calculating battery level, because, pure technicly, a battery cannot house 100% while not plugged in.

Well they did change how they show the battery status in 2.2.1
You still has same capacity.
Think its better it show this way then 100% for 20 minutes before it moved to 99%.

I'm sure this is a ROM specific issue. ON JPX Rom (I think), the charge used to reduce from 100% to 97% instantaneously after removing the charger. This however, was resolved after I flashed to the newer JPY firmware.
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.
Hi.
I've seen lots of advice in several different ways about charging new tech when you get it.
So I thought I'd try a poll to see what the general consensus is.
1) Charge until light is green before turning it on the first time?
2) Turn on without precharge, but then run completely flat before charging
3) It's a Li-ion battery and it makes no difference
Thanks

Many people will tell you it doesnt matter but I know from experience that it does in fact make a difference. When I got my phone (mt4g) I starte using it right away without charging it, everything seemed fine I had an issue with the screen so I exchanged it and got a new one. This one I charged first for a few hours before even turning it on and it did make a difference. my battery seemed to be holding a charge for longer. When I got another battery I read they recommend charging it fully off for at least 8 hours then when you do power it on let it run down all the way. Do that for the first 5 charges and it will help your battery health in the long run.
Another example is my friend got two of the same phone one for him and one for his gf. He started using his as soon as he got out of the store, hers he charged for her because he didnt see her that night. He said the phones are pretty much set up identically, same software, same services running etc.. and he said her battery lasts noticeably longer than his

Thanks for the input. Ya, I have heard a lot of stories like yours.
And even if it doesn't always make a difference, it's only 8 hours, so it should be worth it just to make sure, but when you've been waiting since January for an android tablet and you finally get one in April, 8 hours is forever. ha ha
Thanks
Oh, I suppose another related question is how much is fully charged? Apparently modern devices have a current regulator or something in them that stops it from charging past 95% or something? Not sure on specifics, but from what I've read. You can't charge it passed when the green light comes on anyway?
Anyone know more on this?

Many new batteries will charge to 90% or 95%, then display the light as "fully charged". They will continue to to charge to 100%, drain back down to 90%, and back and forth in order to not stick at full 100% (aka charging over night).
That being said I've heard a lot of talk about conditioning smartphone batteries etc. and for the most part I haven't seen a lot of evidence to prove that it is necessary. Lithium Ion batteries really don't need conditioning or anything as much as you'd think... that's really an old NiCad thing to do.
I did not charge mine when i first got it, the battery was already at 90% about and i simply used it for a day and a half and now i'm charging it for the first time. i regularly get new electronics devices and i never have better problems personally. battery tech has come up a ways in the last few years.
It's well known by now the Li-ion batteries do better with short, more frequent charges. It is not a good idea to run it down until dead. These batteries also do not have a "memory."
Placebo and old habits keep this myth around.

I got my Xoom wifi and plugged it in and turned it on. Couldn't wait any longer.
It's an awesome tablet and the battery lasts all day, with constant wifi and playing.
Thanks for the advice guys

Hi,
This past week, my G2 has had massive problems with the battery draining when I have been doing basic things like web browsing etc.... I can literally watch the battery drop %'s every few minutes... the phone also gets extrmely hot up the top of the phone around near camera, it gets to about 50 degree... and to make things even more worringly it takes all day to charge to full, instead of it charging to full in an hour or so it will barely get to 50% overnight..
Does anyone have any ideas what the hell is going on??? It's running stock EU KK ROM
I'm having the same issue. For me it seems to be triggered when I connect to bluetooth in my car. Once the battery drain is triggered it continues even after I get of the car. I've gotten in the habit of rebooting my phone every time a turn off the car. A major pain but it works until I find a better solution. I've been thinking about wipping the phone but I don't want to go through the hassle if I can avoid it.

First thing I guess would be to try a battery stats app (Gsam for instance) and have that running from a full charge to see if anything is running without your knowledge.
Not even with a separate app, did you guys take a look at the "stock" battery stats?
I had once a big battery drain that was caused by the media server.
If I helped you, please thank me
Ive currently tried every battery stats app i can get my hands on lol..... I've gone through the 50+ battery guide using titanium back up.... I've disabled startup programs.... Geez even Sonic the hedgehog Ep2 was for some reason just always doing something and i never touch it lol.... Anyway I'll keep a close eye on it but i still can't explain the long charge times.... Maybe something will come up
Yeh I checked stock battery stats, the main hog seems to be bluetooth when it's not even switched on :/

What cable you using? All cables are not created equally. Try the cable and charger the phone came with. if that's not it try a different cable.

I actually *think* I found the very unlikely culprit.... Google Chrome Camera!!!!!! Someone else commented on the exact same problems as me on the Play Store... which sounds about right because I've had the charging probs about as long as I installed the app.... So I've removed it and hopefully thats fixed it

I could see the app maybe causing the drain but I think it highly unlikely it affecting charging. I still like the cable idea for your slow charge. Go find your white one the phone came with and try it =)
