battery last 6 days only

Former Member
Former Member over 5 years ago

Setting : Bluetooth On / GPS On / No Music Play / WiFi On / HR On

Activity: 3 hours run on treadmill / regular lifestyle walking 

With above context, battery drained Totally in 6 days.  Is this the spec? In Garmin site shows GPS Mode up to 36 hours while Smartwatch Mode up to 2 weeks. (smart way to protect from disclaimer). But considering not having done heavy activity, I would expect it would last around week and half. Bit disappointed in this respect.

    And the most important things, backlight brightness (and when is it on), pulseox and which watchface? Custom watchfaces can drain battery massively, as do backlight brightness and pulseox.

    I have my own custom watchface, very efficient, pulseox off, backlight at 5% and only after sunset when I move my wrist.

    I'm now at 9.2 days, starting from ~96% and have about 12% left. This is with 7 - 7:30 hrs of gps (running) activity including some routing.

    Also try a hard restart (long press power till it turns off)

    Turn off Pulse Ox.

    Oh and do a search in the forum for other advice. This type of post  comes up virtually every time someone puts on a 945 for the first time so there’s heaps of information out there.

    That's impressive.

    For comparison, I have all the same settings but I use watchface similar to "krystal" (with seconds) and I was at 100% at 7am this morning.  Did a 47 min run w/ music, and a 35min bike without music and I am now sitting at 80% at 530pm 10.5 hours later.  Your battery is better than mine.  I'm starting to lean heavily towards an exchange as I feel like I'm getting shorted here.

    I have exactly the same settings on my 2 years old Fenix 5s and foreruner 945 and I have to charge them at the same time - about 5/6 days but of course 5s has much smaller and older battery Disappointed
