Ok, I wish I had read this forum before buying the F945. My 735XT died (still pissed with that) and had to buy a new watch.
Got it yesterday and It came with a very old firmware. Configured it to me and went to a 1500m pool swim. It drained 6%. Wierd...
Updated to the 3.30 and charged fully around 5pm.
Went out with wife, back home, left next to my bed and when I pick it up this morning it was only 90% WTF?!
I've read that the pulseox drain battery, but I question: what else should I try here to check what might fix the issue?
Thxx
