Since my old battery made slowly limp, I've got this far because the only 5-star ratings here as a substitute. To make it short: Worst experience from the first day. Have after 10 full charge cycles following status: When fully charged, the battery lasts for off-Fi and Bluetooth in pure stand-by operation, lying on the bedside table, good reception, and without any use (just laid) no 3/4 day !!!! No Joke. As has my old battery, which should be replaced, kept still longer. Either it is the Committee, or the entire battery is a joke. I do not know. Therefore: From me clear warning of the part!
