Feedback on battery duration

[iu2frl]

I'm trying to undestand the current battery consumption, the most battery aggressive feature is transmission followed by WiFi, my T-Beam lasted around 2h in tracking mode which is not so good. Any feedback?

How big is your battery in mAh?

[iu2frl]

Should be around 2500mAh but I'm thinking is about to die

[SQ9MDD]

definitely this battery is ruined. I will do a test today. I'll charge the battery to full and after 10hrs of use I'll put it on a charger with a mA meter and see how much is missing. I will repeat the test a few times

[SQ9MDD]

Test conditions:
Sending frame every 180s, fixed beacon, GPS disabled, battery full loaded.

2021.09.23 22:45 - starting test, battery 4.18V (the battery has been charged to its maximum capacity with externall charger)
2021.09.24 07:45 - stopping test, battery 3.94V

After charging the battery back to 100% the charger showed 646mAh
So, during nine hours of operation, the device consumed 646mAh.
That is, the current consumption is about 72mA

[iu2frl]

That's not bad, can you try with GPS ON?
