DDONG Batteries EB-BG998ABY Editorial Review
## Editorial Review The DDONG Replacement Battery for the Galaxy S21 Ultra has received a mixed reception from users, showcasing a blend of positive feedback and Considerable discontent. On one hand, many customers have found the battery easy to install, reporting that it fits perfectly within the device. Some users have praised its performance following the replacement of their old batteries, noting significant improvements at first. However, this positive sentiment is overshadowed by a number of concerning reviews regarding the actual battery capacity and longevity. Several reviewers reported that the claimed capacity of 5800mAh is misleading, with tests revealing actual specifications closer to 4855mAh or even lower. This discrepancy has led to frustration among customers who expected enhanced battery longevity but instead found themselves needing to recharge their devices within under an hour from a full charge. Issues related to the battery's health over time were also flagged, with one reviewer reporting a drop to 82% capacity merely a year after installation. Despite some appreciation for the battery’s fit and initial performance, the overall Consensus leans towards disappointment, primarily due to misleading capacity claims and insufficient durability. ###
