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.

Are you using the OEM charger?

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.
