Stable operation problem of autonomy or battery

I received the watch in time. The watch is very correct. The connection that does very well with the phone. In short everything is working fine but the big problem is that the watch does not take a day. I do not even play with all this time. Basically, it is on standby all day. I look at the time a few times in the day and that's it. My day starts at 7 am and 17h the watch off for more battery. 10h standby time, it's not terrible. I bought it to run and listen to music at the same time but it seems impossible. The watch is also micro sim phone with the player, but how much longer I can call with 20 minutes? I wrote to the seller to receive a new battery. Mine may be defective. I put two stars because the watch works fine. I would put five stars if I get a new battery that takes at least a day and half.
I see that a buyer has even received the watch without battery. If the seller does not need the watch will be empty shunned.
I bought a watch that works fine so I want a good quality battery. This seems logical to me !!!!!
