A question for garmin 7 solar users how much should the battery last after taking it out of the box (standard settings). I recently bought it and I have the impression that it lasts a short time, namely about 11 days, including about 5 runs for an hour. When i charge watch on screen is displayed 25 days but it never last that long.
Estimates are pretty accurate for a pure smartwatch use. Any music playback, GPS activity, flashlight (on the X size) etc. will drain the battery at much higher rate (each hour can cost you a few days…
Im getting about the same or even a bit less with the same usage. Ok i use BT music during runs so that cuts it a bit, but I max out about 7 days...No training gets me 11 days max! All stock, no extra…

Do you have Pulse Ox on all the time? That will give you several days back if you turn it off. Check back through the many, many threads about…

The "estimate" battery life is just a complete fraud! Unless a day has 35h, than its ok!

Well, if that would be the case, you'd be getting more time than Garmin declares (e.g. the 7 days you mentioned would in fact be over 10 days (245/24=10,21) 
I don't let my watch drop below 20 % and usually end charging between 80 and 85 %. In such use scenario, I charge it every 2 weeks on average. With less solar I also use less GPS (not much time for outdoor activity is accompanied by not much motivation to do so during the 'lovely' November weather with first snow, temperatures around 0 Centigrade etc. ;) Still, when I track indoor workouts and send music to headphones... I'd need to charge it twice a week and not every two weeks that I get without GPS and music, still with indoor exercises though. Please also note that MIP display consumes power for each refreshed data. If you keep seconds, heart rate, daily oxygen levels (red LED for it also drains power during the day, so better to keep on it only at night) you'll get significantly less time between charges. And yes, I am happy with the battery life for now. I can estimate the power drain and use time, knowing the actual battery cells' capactiy. It really is pretty efficient. Keep in mind it's less than 500 mAh and lasts for days / weeks, while your phone is probably somewhere between 3000 and 5000 mAh and won't last 2 days. If you use Bluetooth A2DP profile for music, it also drains faster, even with screen off.
