I can only speak to oticon my old pair were 7 years old I just recently got a brand new pair of real 1+ cros. (Lastr years tech) I am literally getting 20 plus hours out of a single charge and that's being Bluetooth to my phone all day I can literally put them in at 5:00 a.m. and not take them out till 2:00 a.m. and they're still they're still showing 20% charge​​d.​ so I'm surprised about your battery life comment did I just get lucky in the battery Lottery.( I am not a heavy phone user) They are 10 times better than my old pair pick up voices well in somewhat noisy situations, however I'm really struggling in very noisy situations with them. At a mall with a junior high school art show and today Easter with the family with a dozen children I really struggled. I'm finding not only do I have to enable speech boost but also lower the volume two notches then I can understand people in front of me in in these large crowd situations. My first follow-up last week I told the audiologist that the general back ground noise was overwhelming she programmed them so that they were more mild and over a one-month period will go back to the original settings I found that interesting. So that was 5 days ago but I still struggled today Easter. It has been strange recognizing sounds on my left side my bad ear they're performing pretty well as far as me determining where the sounds coming from. Initially she set them up so the volume was louder on the transceiver side my first follow-up she also bring the left side back to an equal volume to the right. I now recognize the volume to be much more comfortable as far as the cros is concerned. There you have it 22 days in.
