Slowly charge, then went to reboot cycle

Hi all.

I've replaced my logic board because the previous one died.

With new logic board the phones indicated if it is on charger, but the percentage increased extremly slow, and the phone getting very hot.

This morning my phone went to reboot cycle. (The device on the charger all night)

If i remove the charger the phone switch off.

The battery 1year old, and there aren't any problems with the previous logic board. (The battery werent used for 2months while i got new logic board).

Any ideas? Battery dead?

If you didn't use your battery for 2 months than you probably got your battery stuck in a deep sleep. This is what Apple says about storing batteries:

"Store it half-charged when you store it long term.

If you want to store your device long term, two key factors will affect the overall health of your battery: the environmental temperature and the percentage of charge on the battery when it’s powered down for storage. Therefore, we recommend the following:

Do not fully charge or fully discharge your device’s battery — charge it to around 50%. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge. Conversely, if you store it fully charged for an extended period of time, the battery may lose some capacity, leading to shorter battery life.

Power down the device to avoid additional battery use.

Place your device in a cool, moisture-free environment that’s less than 90° F (32° C).

If you plan to store your device for longer than six months, charge it to 50% every six months.

Depending on how long you store your device, it may be in a low-battery state when you remove it from long-term storage. After it’s removed from storage, it may require 20 minutes of charging with the original adapter before you can use it." -- http://www.apple.com/batteries/maximizin...

The phone doesn't seem like it's really charging. Try using an adapter that is rated for 10 or 12 watts (iPad adapter) and lmk how it goes

Your phone is possessed...Haunted...Cursed....

Lol jk

Bring it to an Apple Store and see what they can do about it. They might not be able to help you because you replaced the logic board yourself, which puts the phone out of warranty.
