The Ororo battery can last up to 12 hours on a single charge. However, this will vary depending on how often you use the battery and what you use it for. If you regularly use your Ororo battery for high-drain activities like gaming or watching movies, you may find that it needs to be charged more frequently. Conversely, if you only use it for low-drain tasks like checking email or browsing the web, you may be able to get away with charging it less often. Ultimately, it all comes down to how you use your Ororo battery and how often you need it to perform at its best.
