Overnight charging on AC

My G1 after I put him on charger goes till 100% and than act like it is not connected to any charger.
Like today it got to 100% and in the morning was on 98%.
I use AC wall charger for Motorola V3.
people tells me that is no problem, should be the same with miniUSB connected to PC.

I believe the default charing behavior of most rechargeable devices is
charge to 100% stop charging until the % is lower then a defined %
then charge to 100% once more

Do not use a moto V3 charger to charge your G1. It charges at a lower voltage and could effect your battery life. Use the one that came with the phone, another HTC charge or a blackberry charger. They all charge at the same voltage.

The only thing I see is the V3 charger has a lower amperage rating whereas the charger that came with the phone is capable of putting out 1A. It might be sending data at night and using more power than the V3 charger can put out.
First night I had my phone I had wifi and gps on with full screen brightness hooked up to the USB on my desktop PC and I was actually draining the battery while it was "charging" It's a power hungry phone when it wants to be. I would look into finding the factory charger.

usb can only charge at most usually 5v. Any miniusb charger will work for it, it wont overcharge it, it will only undercharge it. "smart circuits" if you will, tell the phone to shut off at a full charge, and like previous posts, to stop charging it, and when it reaches said threshold (98 percent) it will charge it, basically maintaining charge, without overcharging alltogether.

Actually, I can tell you that the mini USB charger for my Toshiba G900 will *not* charge my G1, but will charge other devices I have.

UNLESS it charges it lower than the voltage thats needed to maintain a charge ;-)

Question about battery calibration

What is the purpose in doing this?
On to my real question
So anyways I charged my phone to 100%, removed it from the charger and wiped battery stats, used my phone and let it run all the way down and it turned off before I put it back on the charger. From reading you are not supposed to let it turn off. So should I do the process over again?
Thanks.

When I do the batter calibration I let it die completely and that's what it says everywhere so I think you'll be ok unless you really don't see an improvement in battery.

Seriously.. I think the USB charging port is bunk.. I brought the 2 batteries and a wall charger for 9.99 on ebay. I would always have to top off the batteries to they stay full charged...
With the Wall charger.. it's a way better way to charge. I"ve done 4 charge cycles.. and every time I plug in a charged battery off the walll charger it's stays fully charged for a long time.. then it trickles down... I serioulsy don't think calibration is the problem.. it's the USB charging port. There shouldn't be a need to Calibrate your battery.
Just my speculation.

i think he is talking about calibrating your battery in use with a new custom kernel, in which they recommend to calibrate battery.
to answer your question though, like you already know i did the same thing. the response i got from that is that it should not matter.
also i too got the 2 battery deal and wall charger for 9.99 and can deff say using a wall charger charges your phone way better than the included usb charger.

What is this two battery and wall charger?

For the kind of batteries we use in the cell phones, it is never advised to let the battery drain completely - this is stated in the manual that comes with the phone, too.
I believe it is wrong information that the battery needs to be drained completely in any case. Draining the battery completely actually reduces the storage capacity of the battery.

If you have more than one battery are you supposed to do the battery calibration for each one?

i've given her all she's got, but i believe she's gone

x10 has been on the charger for over an hour, still sitting at 1%, lol
when i went to bed at 2:40am, it was at 40%, woke up at 7:30am to 14%, got to work at 8:45am, it was at 4%. been plugged in since about 9am (10:19am now), and it's still at 1%. red LED is on, phone works, but shuts down shortly after unplugging it.
nothing running in the background, airplane mode on.
don't know if it's the battery, or the phone, but it's going back today. and i'll be getting something other than the x10. probably something other than android at this point (4th android device).
this is really weird since i have never had a battery issue up until this morning. the battery always lasted atleast a day an a half.

Is there really an os superior to android at this point?
webos is pretty killer but palm phones suck so far (though the hp pre 3 looks incredible)

at this point?
no
in the future for some current os?
yes
i'm not looking superiorority, just something else.
*UPDATE:
plugged the cable into a different usb slot, apparently that was the problem, lol. it's up to 4% now.

I suggest you to charge in the wall socket. Usb is way too slow.

Its happen to me once a while especially when I change my Rom...What I do is turn off my phone and pull out the battery for few minutes and put it back and charge it..If the battery do not heat up when you charge then the battery is charging but if it become hot than usual repeat same procedure..

yeah, but wall charging discharges faster. slow trickle charging is better for the battery.

This is not true. You can see how my phone is going charged in wall socket.

if you're going to use usb, then expect it to charge slow, also charging it via plug is better and doesn't discharge faster :\

You're correct... the only reason it would appear to discharge quicker is because of the added heat as the phone/battery gets warmer when using the wall charger.
Otherwise the discharge rate would be exactly the same for both methods

Well...u could try "OFF mode" charging. 2.2. see that works or nt...

Svt try this, this works for me.
Flash back too 2.1 stock s.e fw. Go charge for 100% .
It should fix the problem.
When you flash custom rom clean bat stat. Note- dont clean bat stat again when your in a running custom rom.
I have this problem too on j's rom v12. im 100% charged, and try to plug again the charger its charging but the bat is decreasing, weird hehe.

It gets warm but not so much. And very important thing is when you charge in wall to turn off charging right after it reaches 100%. It's not healthy to leave it in.

it gets much warmer than by usb as the current is double....
That's why it would appear to discharge quicker until the battery cools down.

Exactly!
According to my experience, that is the only difference between charging via USB and on the wall. If you do the latter, it appears to be discharging faster at first, but after it settles, it holds the charge just as well.

Ok, you can see my battery temp when charging trough wall socket. When not charging the temp is about 34 degree. So wall charging doesn't make the phone too heat more than a usb.

I beg to differ..mine is much warmer on the wall charger than when charged via usb... Especially during the end of the charge

Rather dramatic title!
I was expecting an equally dramatic story, but pfft! haha

Charging while in use

If I have the screen on while plugged in, my battery % continues to drop and the device itself feels kind of hot. Could I have a problem or is this normal?
My battery life has also not been so great.

Mine doesn't it keeps going up, though I haven't tried playing games. It does depend on what you are doing with the device, if you are running applications that max out the processor it will possibly drop.
The GSII would drain while plugged in if the screen was on. You would see a noticeable drain while using GPS and Music and driving. The only way to make it work was to turn the screen off on the device, the GSIII has a better charging chip in it, and it isn't limited to 650maH (from what I can tell since it is charging when using GPS)

I noticed it while using a usb car cigarette adapter as well as a usb port on my laptop. the car adapter is a 2 amp charger capable of charging a tablet. I will see how it performs with the oem wall charger.

Yeah I was charging my phone earlier using a car was adapter with the oem micro usb cable and they phone got very hot.
What do you guys think? Is this a cause for concern? Do I need to buy a manufacturer approved adapter?

Is it safe to leave the phone plugged in overnight? I usually charge the phone when I go to bed, but I've the this might damage some batteries.

I'm curious about this myself....I'm leaning towards not leaving mine plugged all night. I 2 have done this in the past with other phones and can't be certain but maybe this is a rEason I had horrible batt life despite efforts to Better it. So I'm gonna stick with charging/topping off when I can. Gonna start just charging when I wake up while I'm getting ready for work. I did notice that when battery is completely charged a message comes up telling u so and to unplug. So I'm gonna follow directions haha.

All modern smartphones have chips that control power, and cycle charging appropriately to not abuse the battery. Many phones monitor the temp of the battery and such to ensure a good and safe charge. You can leave it plugged in overnight just fine..

It definitely doesn't like 3rd party adapters. I'm hoping it will at least accept the tab adapter with samsung's cable so that I can charge it at work without buying a dozen chargers, but...
(One charger I used is understandable - turns out its only 300ma. Whoops! But using full 1A chargers wasn't helping either, it went up maybe 1% every 15 mins. The stock charger ran it up fast enough that it was charged from 70% in under an hour.)

I use SetCPU and have a setting to reduce the clock when it exceeds a temperate parameter. You could also set a max clock for when it is plugged into a USB (Computer/Car charger). That could help it stay cooler and charge faster while not plugged into the wall.
I charged from empty to full this morning when plugged into the wall in about 3 hours. I haven't tested on my computer yet.

I went through this when I first got my Evo 4G. I did not realize at the time that the 500mA charger I was using with my Blackberry Storm (horrible device) would not charge my Evo while doing anything power intensive (like using GPS) and I quickly drained it on a car trip.
I went on Amazon and bought a $20 Schosche iPad charger that claimed to provide 2.1A which should be plenty. On that charger the phone would charge while using GPS but very, very slowly.
After some more research I found that some chargers caused the phone to switch into "USB" charging mode and others would switch it to "AC" mode which would draw much more power and charge faster.
This is the charger I ended up with and it works great:

My Evo charges just as fast as it does on the OEM wall charger. I don't have my SIII yet (thanks Verizon for being the LAST in the US to ship them out...) so I can't yet say if this holds true for the SIII but I assume it will. At $1.22 it's not much of a gamble.

Is this normal

Have a stock t-mobile nexus 6p and I think it's not charging correctly. As you can see it says 3hrs till fully charged. Any ideas

As far as I can remember it did charge fully in about 1hr 1/2. But now for some reason it's taking sometimes 4hrs. I'm thinking it might be a faulty charger.

Sounds like a faulty charger or cable possibly.

Do you happen to know of a good replacement?

One off of google play store?

yes and no
its all relative... remember that the "handshake" between phone and charger will indicate if its charging rapidly based on the resistance.
thats why using a bad cable on a normal charger will say the same... and cause damage to the crappy charger
now, if this is stock cable and charger, it would tell me that the 6P is drawing less power than the charger has... that doesnt happens just because, to me it sounds like other factors...
for example, a phone that was outside on the sun or its warm, will not draw 3A and potentially get the battery even hotter to the point of damage.. i can see it drawing less power, and controlling the temp... which in turn the current draw will dictate the ETA for full charge...
for the above example... turn phone off... put it over your car's AC unit at full blast and chill it for a few mins.. let it sit another few mins to ensure the temperature of the device is indeed cool..... then turn on, and charge again... should draw more than before in a few minutes
