Got my Forerunner 245 now for 4-5 days and already had to charge it 2 times.
Yesterday I had it charge full till 100% and now (22 hours later) its already on 43%, almost everything is turned off and in this 22 hours I had 1 run for 1 hour.
Should I contact Garmin? or I need to charge it few times from 0 to 100??
Who can help me?
Hi,
Charging from zero to 100 is not necessary, as the battery is lithium ion.
Just for your comparison; my FR245 lasts 5 days including 3 runs of an hour without music and 2-3 hours a day bluetooth on with smartwatch function.
Do you use any 3rd party watch face or app on the watch? If yes, I would de-install it and reassess the battery again.
Your watch is indeed draining faster as described in specs. I would advise to contact Garmin support. Did you already performed factory reset (that will be probably the first question they will ask 
)
Hope this helps.
Cheers, Fer
