Setup for battery life

Hi guys,
Hope you all good.
I'm new to the fitness/activity tracking devices world and I just bought the forerunner 235 since I'm mostly running and biking.
I read/watched a few reviews before (Rizknows and DC Rainmaker were the best) and I kinda knew in advance that the battery life was not impressive.

All that to say I want to check with you guys, from your experience, what would be the best setup to optimize battery life and usage. I'm trying to get to 4 days before charging and so far my configuration is as follows:

- Bluetooth on (for sms, calls and Slack notifications - not emails since I use Mail and not gmail app) but on my iPhone the app is closed (so I don't have any data for weather and calendar unfortunately)
- When I'm on an activy: GPS+glonass
- HR monitor 24/7
- No custom facewatch or app
- No connected device to the watch

What do you think? Any advice?

Thanks!

I'm not sure where you read that this watch's battery life was not impressive. I think it is fantastic ... one of it's nest features! Every Mon-Fri I run 5K after work (GPS only ... no need for GloNass for me), so that's about 2.25 hours GPS. I have notifications turned on (email, text, phone), 24/7 HR tracking, steps, sleep tracking, custom watch face (Optimus). I also have no other external BT devices

A full charge lasts me 7 days! I charge on Sunday evening and by the next Sunday when I charge again, I still have 12-15% left.

from your experience,_…‹snip›… I'm trying to get to 4 days before charging and so far my configuration is as follows:

- Bluetooth on (for sms, calls and Slack notifications - not emails since I use Mail and not gmail app) but on my iPhone the app is closed (so I don't have any data for weather and calendar unfortunately)
- When I'm on an activy: GPS+glonass
- HR monitor 24/7

As a rule of thumb (in my experience with my FR235 over a period of twelve months),

Bluetooth enabled, Smart Notifications enabled, Activity Tracking enabled and Wrist Heart Rate enabled in everyday use ⋍ 10%(±1%) battery consumption every 24‑hours
GPS enabled (without GLONASS), Wrist Heart Rate enabled and no ANT+ sensors connected for outdoor running ⋍ 10%(±1%) battery consumption every hour

what would be the best setup to optimize battery life and usage.

Set the backlight timeout to the minimum that it takes you to read what's on a data screen at a glance while running.
Disable wrist turn as a backlight trigger if you don't need it. (I don't like running at dusk or in the dark, so it doesn't make much sense to enable the backlight by wrist turn; if I really want the backlight to come on, I can just press the button.)
Using Smart recording instead of Every Second recording may save a little bit of battery power (but not by all that much).
Don't enable GLONASS unless you really ‘need’ or want it.
