Anyone else notice that when the mytouch is plugged in and charging, it drains and results in a lower battery level while using apps and games? I understand that some of the charge goes towards running the game, but to actually be draining the battery while it's plugged in? My old hd2 never seemed to do this.
FWIW, I usually get about a thirty
Ma drain while the phone is idle, whereas with my hd2 would get a 6ma drain, and I typically have them both under the same settings. Strange!

Even under the most intense usage, the battery should always charge while plugged in. If your battery level actually decreases while plugged in, I'd say you have a bad charger or battery.
That's what I'm thinking. The charger I'm using right now is a rocketfish micro usb adapter attached too a mini usb cable, plugged into my keyboard at work. Again, my hd2 used the same set up and charger and never had this issue. Perhaps not coincidentally, the computer never reads the phone as a device and never has.

USB charging does not supply enough amperage to charge the battery and carry a moderate CPU load.
You will also notice that it takes longer to charge on USB. I use a dock setup in my car, which registers as USB charging, it only slows the drain when I actively use GPS.

I had wondered about that, since I knew USB provides less amps than a wall charger, but I guess I've never put enough drain on my phone while plugged into USB because it always continues to increase the charge.

Hi
X10 is my first touch cell phone.
When battery is 30% i put it on charging it start Discharging till 0% and then phone go to shutdown. After sometime it start but take too long to charge 30% of the battery.
Is it normal for X10..???
Please help me if anyone know about this.
Thanks
Are you charging via usb or by ac adapter? usb charging does not seem to provide enough juice to charge the battery.

from my experience with mine is up to 10% or 15% im not sure. theres a blinking red then after that its solid green..but charging is really slow on this
im usb charging at play around with it and its actually draining battery
not sure if this is normal but thats what im experience and most of the aftermarket charger out there doesnt work very well with this device
You need a charger with at least 850mA capacity to be able to charge the phone normally. USB charging from computer is slow as it is just 500mA and if you are using the phone for heavy stuff like watching video it may actually lower battery percentage instead topping it up.
Most aftermarket generic USB chargers are 500-550mA especially car adapters, some are even lower.. Make sure you get properly rated charger for this phone to avoid any issues.
Is it alright to have the SGT plugged into a USB port all day (approx 9hrs) ? I'd like to have it keep its charge (maybe even gain a little) while I'm at work so I can have a decent amount of juice for the trip home and until i go to bed. Or is this a good way of burning out my battery real quick? Thoughts?
Oh and as a side note on USB charging, I was able to get from 15% to 99% in 7hrs with the screen off the whole time.
Is it a slow-charging USB port? Or is it a powered hub? If I'm not mistaken, slow-charging a lithium-ion based battery pack is actually better for its life as opposed to rapid charging.
Its the regular port on the PC not even high speed usb so i guess it isn't powered.hmm guess the charging part is OK..but what about leaving it plugged all day even if the battery is at 100%?

All usb ports are powered by definition. They can supply up to 500ma (half an amp). Dont worry about leaving your tab plugged in, devices are smart enough these days not to overcharge the battery.

Coda is right, technically they all have power . If not, how would any device charge? I guess I really meant to say USB ports charge at a higher MA or something for rapid charging (wall-socket USB adapters?).
Also, Coda is right again. Devices these days are fairly smart. I typically leave my HD2 plugged in all the time with no problems.
itll be just fine plugged in!
ive been part-charging mine at random intervals (sometimes for 20 mins at a time a few times a day) and leaving it charging over a day from both powered hub and charger over about five months... though i have had two or three near total discharges
the battery has got better, which is what you would expect from the tech - sammy even provides a nice notification telling you the device is fully chraged
i wonder if they put that in there to account for unexpected battery problems down the line? in any case, ive read that low-powered charging, even unregistered by the battery, will increase the lifetime of the battery and also charge at approximately the same rate... ive seen this with my phones charging over pc usb
Great! Nothing to worry about then. The tab would look really cool on my office desk sporting the same screensaver as my PC ..'the Matrix' scrolling code.
I think it is OK. I bought a 2d adapter, one for the office. Since Sammy is selling docks, it also means that it can be powered all times. On the other hand I remember my Archos which I used to leave it on its dock all times... battery was killed in a short time. When you sell multimedia charging docks it means that you can leave it there, no? Not in the case of Archos.
hello would like to know which is more convenient to charge the battery on or off the Atrix and benefits of each loading mode
Thx
Sent from my MB860 using Tapatalk
Atrix on and sleep/idle wont charge as fast as of because of things running CPU load.
Atrix with no wifi, and bt on, and normal sync. Its taking mv's per second vs off where its able to gain the same charge rate while off. ( bare minimum resources used)
if you want to know what is better for your phone, I think it's the same.
As Ciloteille said, if your phone is on, it will take more time to load, that all for me
It's better for battery to charge slowly using USB from PC. Also, for battery is better to reduce heat. For example if you charge and play games, processor and batter will produce more heat.

Can u explain any on why its better to charge of a PC USB? Is the lower voltage producing less heat the reason or is the slower charge more efficient for another reason?

Basically for every battery is better to charge slowly because chemical process is less aggressive and in the same time produce less heat. PC USB can not provide enough current as charger.
I recommend to read this article How to Prolong Lithium-based Batteries .
PC USB is 5volt correct? Were as most wall charger or car charger is 12 volt?

PC USB is 5V but charger is also about 5V. Difference is that PC USB 2.0 can provide 500mA and chargers more. For example Motorola charger provide 5,1V and 850mA. That's way charger charge battery faster. Some charger could provide 1000mA or more.

Ya that what i was just looking at. Basically what i am gathering from your info and that article is most chargers are designed to fill the battery fast, but what you reall want to do is a slow almost trickel charge like with a car battery were a low steady voltage and amperage is applied
Chargers are designed for fast charging just because users wish to charge battery faster is possible. They don't care about battery. Anyway modern battery will last longer than ordinary possession of the phone.
mmmmm and then I noticed that when you charge the battery with the phone off, it will download more slowly than when I load it on

Mine does that if i turn the phone off, but if i let it runn all they way dead i can fully charg it and the phone never turns on until i do so
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.
Sent from my SAMSUNG-SGH-I747 using XDA
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.
I'm unsure what's wrong!!!
My phone has been fine, until it died today. I practice a 1 charge a day rule and I let my battery drain completely before I even think about putting it back on the charger.
Today, my phone died a littler earlier than expected, but that's okay because I was using my iPhone for most of the day. I got home at about 11PM and put my phone on the charger at 11:15PM. Here it is, 2:25AM and my phone only has 30% charge.
I've never noticed it charging this slowly before because I typically put it on the charger before I go to sleep and take it off when I wake up. This doesn't seem normal from ANY phone that I've ever used or troubleshooted in my life.
Why so slow? Is everyone's phone just as slow or should I be concerned?
Edit: I am using the charger that came with my phone in the same wall outlet that I've used since I got the phone. Nothing else is plugged into that outlet, either.
It would seem sensible to try a different charger and power outlet.

Your should be at 100% in that 3 hours. Try using a tablet wall charger.
With my phone, sometimes it charges in a flash, and sometimes it's charging for hours, idk why they do this.

I don't have another charger. All I own is Apple products, unfortunately.
I've done other other outlets throughout the house before posting, but I wouldn't see why the one I'm using is compromised in the slightest. It's charged the phone fine since I've gotten it.

The only Tablet I have is my iPad. I was thinking about just using the A/C adapter, but I was worried that that might mess something up with my luck. LOL.
You can't use the iPhone\iPad chargers as most of them don't comply with the USB charging standard (It will only charge at 500ma, the limit of USB charging).
You said it died quicker than usual as well? Sure nothing is running that drains the battery? Check the battery usage in settings after leaving it unplugged a while and see if you see anything that's using a ridiculous amount of battery.
I've had the same problem. Sometimes I plug mine into a wall charger and it reads Charging (USB) which may be your problem. Other times it reads Charging (AC).

It's been off of the charger for about an an hour and a half and nothing out of the norm is draining the battery. Screen on time is at 40%, but that's because I was reading all of my sports news and stuff from my device.
Interesting thing to note: I'm at 79% on my Nexus 4 after about an hour and a half unplugged and doing regular browsing. I'm at 98% on my 4s with doing just about the same things as I've done on my Nexus 4, and even watching a YouTube video on my 4s. I've also had a great deal of voice calls and texts this morning to my iPhone. They were neck and neck when I first got my N4 on December 10th. Now, it's dying faster. The only difference is that I've installed Spotify on my Nexus 4 since then... Which isn't running.

It was reading USB last night! I thought that was normal, lmao... Thinking it meant "there is a USB cable charging it and not wireless charging."
Hm... The plot thickens, I guess.
Yeah it sometimes reads USB but if you unplug then plug it back in, it will change to AC. Not sure how to fix it but that's your problem right there.
Question: are you stock, rooted stock, or different ROM?
