Unable to turn on phone while charging it

While the phone is off and plugged in to the wall charger, I'm not able to turn it on. The battery icon turns grey and stops moving.
To turn it on I need to unplug charger.
Is this normal?
Thanks in advance.

are you using the right charger? i know using a blackberry one can mess up the touch screen whilst plugged in.
Well I guess so. It's the travel charger i was using with my old GT I9000S.

It's not totally impossible that they all could have an issue. Are you charging them using a charger and leaving them on it for extended periods of time? That's a killer for lithium ion batteries.

Also, what kind of charger are you using to charge them?

That could be part of your problem too. It's best to use an HTC charger for an HTC phone because they circuitry is designed to charge HTC batteries. It's best not to mix an match them. The amperage could be different.

Well I thought by leaving it on the charger till it turn green I unplugged it but the most it goes to is 70%,can't even calibrate it

It's been proven calibration doesn't help. I can even attest to that. Try letting the battery drain completely. Then charge it full while it is off. Then disconnect the battery cable and reconnect it and let it charge to green. Let it sit for 20 more minutes. Or charge fully and reboot your phone.

You need an HTC charger my friend. Charger voltage matters.

I've got the same problem. I bought the wife a tbolt off craigslist cuz she liked mine. It won't charge past 3900 mv. I can take my fully charged battery from mine and put it in hers. It'll show like 30 percent charge and 3900 mv on battery widget. Even tried a power mat in case it was a USB port problem to no evail. Different roms, differnet batteries, differnt chargers
If I knew what was malfunctioning I could change it out with a parts phone I have but don't know where to start
Extended batteries typically don't show the correct percentage. The thunderbolt wasn't designed for them so they don't always show correctly. Once it shows full reboot. After you reboot and charge to full do it again. Do it until you reboot AMD it stays the same. If it doesn't the battery is probably bad. You can check the battery condition in your settings about phone.

S4 battery drained now doesn't turn on

I've tried every suggestion on the internet I could find
After my battery drained my s4 refuses to turn back on
Even when I charge it, there's not even a light indicating its charging (I've used multiple ports, wall chargers, and cords)
However, it got really hot when I left it charging over night, however, it still didn't turn on
What should I do?
