2.70 - Awful battery life?

erik29gamer

My 245M upgraded yesterday, then I fully recharged it before leaving work.

SP02 was enabled, and I wore it overnight, but have not used GPS/Music or recorded any activities.

I'm down 30% in less than 24 hours right now. That's a pretty major dropoff in battery life.

Has anyone else experienced the same?

    I charged my phone on the 29th and it’s now at 38 percent. I run with a stryde footpod and the Suunto smartbelt. 5-20ish miles. If your battery is bad check your settings. I don’t sleep with the Sp02 on and I have all phone notifications off. I think it’s a running watch and not and Apple Watch so I don’t need that crap. Hope this helps

    Try again with Pulse Ox off while sleeping. That alone can have a big impact on battery.  In fact, when you turn it on with GCM, you get a warning that it will significantly impact the battery life.

    Updated yesterday afternoon via USB, which also charged it to 100%, then powered the watch off and back on again. Slept with it on (no SpO2).   It's about 15 hours since updating and I have 98% battery.  Seems OK.

    Thanks for the tips everyone, I must have missed that warning. I think the issue is bigger than just pulse ox though. If I'm correct, that only measures overnight correct?

    I just did a 45 minute run with GPS/Music and lost 30%, even with tracking set to smart. Maybe that's normal, but coming from a 235 it seems very high drain.

    Is that with GPS only or GPS+GLONASS? Also music really kills the battery.

    Music seems to have a larger impact than GPS

    Absolutely, that’s why music more then halves our battery time

    For all my runs I've calculated will get about 250mins from gps+music on a run. GPS smart mode. About to go for an hr run with gps+glonass+music (non smart mode) Will let u know my findings

    Smart tracking shouldn't affect battery. The watch is still collecting GPS at the same rate, it just doesn't write all the points to the file to save space.

    I expect about 10% battery loss per hour of GPS usage, so for a 45 minute run I'd expect 7-10% battery loss. I have the non-music 245 so I don't know how much music affects  battery life.
