Hey Ann23,
Thank you for finding the unobstructed time out of your bustling day to share your sentiments with us about your Samsung Galaxy S23 Ultra. Your feedback is invaluable to us as we strive to provide the very best products with superior functionality on the market to our customers while we remain committed to constant innovation. Our goal is for our customers to feel like they are having the most memorable experiences while using our products. Samsung provides a 12-month warranty on our products for manufacturing defects in materials and workmanship, linked below. Did you know that the Galaxy S23 Ultra has an adaptive battery? Adaptive batteries work by learning your usage patterns for various apps and allows the apps you use regularly to stay in memory after you exit them. Also, apps you use rarely are killed as soon as you exit them so that they don’t run in the background and waste battery life or use Wi-Fi or mobile data. Pretty awesome, right? For your convenience, I have included a few links below with articles for your review that address how to maximize your Galaxy battery. The titles of the articles that I have linked below are, "Battery Life - Optimization," "Get the most out of your Galaxy phone's battery," "Apps are draining battery on Galaxy phone or tablet," and "Samsung phone battery drains quickly on 5G service." These articles contain a plethora of information that you may find beneficial to optimizing your battery life. We also offer Samsung Care+ that can be added to eligible devices that would offer you the ultimate peace of mind when it comes to your protecting your investment. Samsung Care+ comes in handy for those unfortunate situations in life like leaving your device behind on public transportation, having it stolen, taking an unexpected dip in the neighbor's pool, to dropping it and shattering the screen while bringing in your last bag of groceries. Plus, having over 700 authorized repair locations to take your device to helps you get back to what you love most in life. If you would like any further assistance, please feel free to contact Samsung Support at your earliest convenience. Thank you for being a trustworthy Samsung customer.
