I have had a galaxy tab 4 for about three months. it was bought new and has never kept a charge well but recently it really drains quickly. it was 100% and was not used and when I turned it on to use it it was almost dead. any ideas?
Thanks for reaching out to us with your question. Have you checked the settings in the device to see what is using the battery? Are the applications installed on the tablet up to date? Do you have any apps on the tablet that are set to auto refresh, such as Facebook? If you have already checked all this, I would suggest taking it to a Sprint service and repair center to have a technician check it out. They can provide you with hands on troubleshooting and run diagnostic testing that we are unable to do over these forums.
