    Uninstall any other battery apps. remove battery wait 30 seconds and put battery back in and start phone. make sure you use the original charger and plug it in. if this doesn't work, try this next. with charger connected, shut down phone and remove battery. wait 30 seconds and install battery and power up. they should charge now. I had this problem with my samsung charge with 2 original batteries. they both all of a sudden said they were non-supported battery? one battery work fine for the first step and the second battery worked with the second step. Good Luck!

Try a new battery. Many phones do this when the battery goes defective.

It is also possible that the battery control circuits in the phone are defective. This is less common.

Time to replace battery. Also if you have purchased a battery from any source except from the place where you purchased the phone, chances are it is not an OEM battery. Non-OEM batteries work but they get hot and sometimes you will get an error message indicating that the battery is a NON OEM battery and not supported

Hey, I had a few samsung INNOV8's some time ago... I unlocked 1 of them at a service shop and it suddenly started having battery problems like it would only last a maximum of 1 day... now i still have 1...

Battery lasting one day is about right for an aftermarket battery.
I have an innov8 and with my standard I get maximum 2 days and less than a day with the "cheap" battery.So if you do unlock,you wont be loosing much.
The innov8 is a great phone ,love it ,but battery life, sucks!

My phone says "battery type non supported"

take the battery out, blow on all the ediges, as well blow in where the phone was sitting in the phone. just make sure the battery is getting a good connection with the phone. snap the back of the phone back on and make sure its on the way on.

if you still have issues its possible your battery has gone bad and you will need to get a new one.

Mine did the same thing. Took the battery out and gently scraped metal prongs on battery with my fingernail. Seem to clean them off(maybe some kind of buildup) now it is charging. Hope this helps.
