Battery drain and strange percentages

To start, my watch is fair few years old now so possibly the battery is just dying. Now to what's going on

My last couple of runs have had huge drain on the battery. 21km in a little under 2 hours and it drained 63% of the battery. Last night approximately 35 minute run drained 23% of the battery. This is with GPS going, wrist heart rate on, and bluetooth on to headphones. I know bluetooth especially drains fast but this seems a bit rediculous.

Now in the last couple of days I've turned the watch off and back on again and the battery % has gone up around 3-5% each time I do. Then yesterday it had 7% battery left. I plugged it in to charge and it immediately jumped to 21% and about 6-7 minutes later it was at 83%. Not sure if the new 13 firmware is messing with things or whats going on. Battery drain only seems to be bad during activities using the GPS, bluetooth, and heart rate sensor.

Did a factory reset on the watch before the run yesterday so seems that didn't fix anything. As I said, could just be an old battery giving up the ghost.

Any suggestions or are others having similar things happen?

Thanks

My battery time went from 5-7 days to less than 1 day with version 13, waiting for an update to resolve this. Hopefully soon.

My FR245 doesn't have such a battery drain, but it is noticeable. I also have the effect, taht a reset or even plug into a charger increases the level 3-5%. The watch is one year old and I have these problems since several months.

Li-ion battery need to be calibrated time to time.

Charge to 100% / Discharge to 0% / Charge again to 100%.. Use "slow" up to 1A charger or 0,5-0,9A computer USB port. Don't leave charged watch "on wire" for a long time.

But why is the usage in smartwatch mode rather fine but during activities way too much? And if I restart the watch 1-2 hours after the activity or plug it into a charger for a few seconds the level increases 3-5%. The watch is 1 year old and I notice that since a few months. That drain during activities is new.

This is the same for me, 245 v13.00, battery is down to 20% a few hours after charging. Have it 3 years never been like that. Hopefully they sort it out.

Just tried this and it made it worse haha. Just in watch mode it would only go down a couple of percent a day. Now since doing this this morning it has gone down nearly 10% in a few hours. While charging through a computer USB it only took 45 minutes to charge from 0-100% which seems very quick. Maybe my battery is just stuffed.

It is most likely not your battery, mine went from fine to garbage with the firmware update.

Just noticed this a few days ago but I have the same issue. Charge to 100% and about 24 hours later it's about 30% and typically 5-7 days on a single charge.
