Not Charging?

While I have my phone plugged into the wall it'll charge at idle. But if im playing zynga poker while it's plugged in, the battery will drain. Now while im playing I notice the battery gets pretty hot. Doesnt drain while im surfing the web or using xda developers app and such. Not sure why this is happening. The battery is only about a couple months old. Verizon gave me a new battery when I called in for a replacement phone.
Anyone have any ideas for this?

It could be because it is charging and useing an app that uses a lot of battery and functions of the phone. I really have no idea though. Just a thought.

Could be that, this is my 3rd droid charge. Not sure if my battery drained on the last ones

Phone is using more power than the wall is providing. Are you using the OEM charger?

I've noticed if I use very processor and data intensive apps while plugged it my phone will get a little warm

Charging current is controlled by the kernel. It's using more power than is allowed by the kernel. This is fairly common for me-especially when I'm hammering the LTE radio. When you want it to charge faster, leave it alone.

Alright good, atleast I know it isn't a problem now. Just making sure my phone isn't crapping out on me.
Thanks everyone

Yep, I think it's regulated at 800ma by kernel so it sounds like you have too much juice-sucking apps.
Your battery charges best if your phone is powered off.

Battery life

Yesterday I was off charger for 4 hours, plugged in my phone and got the signal that my phone was fully charged. Now five minutes off the charger and I am down 2 percent.
In addition, I ran Tunein Radio, and Navigation and I was losing 5 percent of battery an hour, even though I was plugged into a charger. Thoughts?

What amperage is your charger my boy are you using the stock one from the SR or not if you are is it making a high pitched noise if your not again amperage is important if your using anything under 1amp it might not charge if your using your phone especially
Also navigation and radio are super intensive cheap ass charger wont charge make sure you get a good 1 or 2 amp charger

Okay. With the LG Rev, and a Rom, we could easily get by with stock.
Lots to learn about Sammys

I was using navigation, hence I was driving. Sorry, I didn't mention it clearer. I have a 400ma charger. Time to upgrade that too.

I have trouble at my mom's because her electrical stinks. Same charger and outlet?
Sent from my SCH-I535 using xda app-developers app
I usually charge it off my PC with no problems or from my wall. Yesterday I flashed hyperdrive ROM and the phone went from 23% to 0%. I assumed the battery needed calibrated so I did just that. It was on the charger for 8 hours and got to 20%. I flashed bone stock ROM with stock kernel and now I'm losing percentage on charge

Try a different cable
Another cable should do the trick. I had the same problem and used an old, thicker LG cable and it fixed it.

Nexus i9250 charging issue.

My other phone nexus i9250 is having problem with charging.
It charges when it powered of but as soon as I turn it on it stops charging.
Kindly help
