Hello Gomarlins,
Thank you for finding the available time out of your lively day to share your sentiments with us about your Samsung Galaxy Tab S8 Ultra. Samsung provides a 12-month warranty on our products for manufacturing defects in materials and workmanship, linked below. We also offer Samsung Care+ that can be added to eligible devices to provide an additional layer of protection for you and your devices. It offers you that ultimate peace of mind for those unanticipated situations in life like leaving your device behind in a coffee shop, to spilling your drink on your tablet and it causing damage to your speakers, to having your device stolen, or dropping and breaking your screen. With over 700 authorized repair locations available nationwide, getting back to what you love most is our top priority. For your convenience, I have included a few links below with articles for your review that address how to get the most out of your Galaxy battery. Take a look at, "Battery Life - Optimization," "Get the most out of your Galaxy phone's battery," and "Apps are draining battery on Galaxy phone or tablet" for a plethora of knowledge that you may find beneficial to optimizing your battery life. Without having more details available regarding what else you may be experiencing with your Galaxy Tab S8 Ultra and without being able to ask you any follow up questions to clarify what you have shared with us; I recommend reaching out to Samsung Support if you would like help troubleshooting your device or if you have any questions for us. We're always more than happy to help! Thank you for being a treasured Samsung customer.
