Hey there Rayfwilliams, Thank you for taking the opportunity to reach out and share your candor with us regarding your experience using the Samsung Galaxy Watch9. We appreciate your sentiments as we work toward improving our product line to better suit the needs of our customers. The Galaxy Watch9 40mm version has a 390 mAh battery while the 44mm version offers a 445 mAh battery. The higher capacity allows your Galaxy Watch9 to require less frequency in charging. This means you can keep the Watch powered throughout the day with minimal downtime. While you're using your Galaxy Watch9 without enabling AOD, you should expect to receive about 40 hours of usage time. Up to 30 hours if you're utilizing AOD! To fast charge your new device, please use the dedicated EP-OL300 wireless charger paired with a Power Delivery wall adapter that supports at least 5V/2A. The Watch9 utilizes a proprietary charging layout and a deeper internal sensor stack. Its redesigned health sensors push the internal charging coil further from the outer casing, making the watch incompatible with flat Qi chargers, older watch pucks, and direct phone reverse charging. You can still reverse-charge the watch using a Galaxy phone by plugging the in-box USB-C puck directly into the phone's port. If you're experiencing less than anticipated battery life on your new device, please check out the resources shared below to help resolve what you may be experiencing. If you have any questions for us or if you would like further assistance, please let us know by reaching out to Samsung Support. Thank you for being a staunch Samsung customer. - Debra Samsung Support smsng.us/Samsung-Support Warranty Information smsng.us/Warranty-Info Facebook Messenger smsng.us/Facebook-Messenger X Messages https://smsng.us/X-Messages Samsung Community smsng.us/Samsung-Community Galaxy Watch9 https://www.samsung.com/us/watches/galaxy-watch9/ Reduced battery life on your Samsung smart watch https://www.samsung.com/us/support/troubleshoot/TSG10007314/Samsung US Originally posted on Samsung US

Good day QuincyB, Thanks for sharing your thoughts with us regarding your recent experience using the Samsung Galaxy Watch9. Samsung provides a 12-month warranty on your device for manufacturing defects in materials and workmanship. We also offer Samsung Care+ which is similar to an extended warranty and an insurance package combined. It can provide protection beyond the standard manufacturer's warranty on your eligible devices. It could cover events like accidental damage, mechanical breakdowns, and potentially theft and loss. Samsung Care+ offers you the ultimate peace of mind when it comes to protecting your investment. Our partners at UbreakIfix are also available to assist you with any repair needs you may have. The Galaxy Watch9 is offered in two versions: 40mm with a 390 mAh battery and 44mm with 445 mAh battery. The higher capacity versions allow your Galaxy Watch9 to require less frequency in charging. This means you can keep the watch powered throughout the day with minimal downtime. While you're using your Galaxy Watch9 without enabling AOD, you should expect to receive about 40 hours of usage time. Up to 30 hours if you're utilizing AOD! To fix sleep tracking gaps on your Galaxy Watch9, please restart your device, update the Samsung Health app, and ensure that your Galaxy Watch9 fits snugly one finger above your wrist bone. Be sure to wear the watch snugly on the top or slightly shifted on your wrist, not too loose, or the sensor will lose contact and create data gaps. Also, make sure to clean the glass sensor back with a soft cloth. Please take a moment to review the resources shared below to help resolve what you have described. Let us know afterward if you would like further assistance by reaching out to Samsung Support. Thank you for being a dedicated Samsung customer. - Debra Samsung Support smsng.us/Samsung-Support Warranty Information smsng.us/Warranty-Info Facebook Messenger smsng.us/Facebook-Messenger X Messages https://smsng.us/X-Messages Samsung Community smsng.us/Samsung-Community smsng.us/Samsung-Community Samsung Care Plus smsng.us/Samsung-Care-Plus UbreakIfix Galaxy Watch9 https://www.samsung.com/us/watches/galaxy-watch9/ Reduced battery life on your Samsung smart watch https://www.samsung.com/us/support/troubleshoot/TSG10007314/ Properly wear and clean your Samsung smart watch https://www.samsung.com/us/support/answer/ANS10003364/ Use Samsung Health sleep monitoring on your Galaxy Watch https://www.samsung.com/us/support/answer/ANS00090402/ Galaxy Watch is not tracking sleep data correctly https://www.samsung.com/us/support/troubleshoot/TSG10004960/Samsung US Originally posted on Samsung US
