I'd like to check if its safe to leave my phone charging for 7+ hours. It will be nice to leave the phone charging as I sleep.

But without a timer this would easily mean 3+ extra hours of it being left charging when it's already fully charging.

Will overcharging on a daily basis lead to any problems?

Thanks.

The phone stops charging at 100% and lets it drop to 95% before starting to charge again to combat overcharging.

So u people say that custom Roms can be safe when we over charge
By automatically stopping it or discharging a little bit.
I use a galaxy note.however replacing it with a htc one...
I won't mod them by installing custom Roms and all..
What if I do the same wit it now?(overcharging?)

Its not possible to overcharge it. And the ROM you are running will have no effect on this behaviour.

Its all controlled by the charging circuits inside your phone.
They read the amount of millivolts that your battery is giving out.

These are not exact numbers (just an example)
Low battery - 800mv
You put it on charge
When your phone reaches 2000mv - full battery
it will stop accepting voltage in
While it is still plugged in your battery can fall to about 1940mv at which point it will start charging again until it reaches 2000again.

Ok cool, I see. Despite what you said above, I also have been doing this for a short period but when i get up in the morning, my htc one m8 are hot at the back. When i remove the charger the heat disperses. Can you tell me if this is normal? Also my phone are using 4.4.2 which is not the latest update.
