Battery life

[HerrAugust]

Hello, I notice that with screen brightness to minimum, Wifi turned off and Bluetooth turned on and connected to my smartphone, the battery lasts a nothing. Is there any way to make it last at least 1 day? I need the BLE to be turned on.

[sharandac]

At present, there is no way to save more energy. The hardware design lacks an external 32.768kHz crystal to save more power with Bluetooth turned on.

[HerrAugust]

Thank you for the answer! Ok, but the battery only last around 4 hours with wifi and screen turned off and BLE turned on (and connected with an Andoid8 smartphone) all the time... Am I the only person in this situation?

[sharandac]

That's really very short. Which version of the Watch are you using?

[jusjak11]

Sorry to jump in, but I have exactly the same issue making the watch unusable. In my case battery lasts for about four hours with everything off, including bluetooth. The version of watch TTGO 2020 V2. Is there a setting in your firmware that I am missing, or something else? I read that there is a possibility to put all major chips, including RTC, into a deep sleep, thus making a battery to last couple days.

[jusjak11]

Just to add that I measured battery capacity which is supposed to be 380mAh and is definitely above 300mAh which is OK. The real consumption of the watch is about 80mA with WiFi, BLE, screen off.

[Crsarmv7l]

Hi all, I too had the 4 hour battery life. It is due to the Bluetooth "Always On" setting. After digging through the code more, I realized "Always On" isn't really necessary as the Twatch and this firmware has wake ups scheduled at low cpu speed and the frequency is such that you wont miss anything.

It also extended my battery life substantially to almost 2 days.

@jusjak11 I cant remember off the top of my head where exactly the programming is, but consumption should be even lower than 80mA as Sharandac scales the cpu frequency on sleep.

[jusjak11]

@Crsarmv7l Hi, I am not sure I understand you properly. My consumption is 80mA (which makes it total 4 hours) now, with sharandac firmware on and bluetooth, WiFi, screen off. Is there a setting in sharandac firmware to go to sleep? Where is this "Always on" setting: in original firmware (the one that watch came with) or sharandac firmware (one of source files)?

The consumption should go down to 7-8 mA in order to have watch working for 2 days.

[HerrAugust]

I think I can reply you. The 'Always On' settings can be found in the GUI. Turn on the watch with the current firmware, go down, right, right with the swipe and then click on the Bluetooth Settings. Among the option, you'll find find the 'Always On' one, which the other user suggests to turn off. Hope it helps!

Can you confirm what the other user says please? Do you have the same battery duration?

[jusjak11]

Unfortunately this setting "Bluetooth on" is set to off in my case. So, it is not the real cause for such a high consumption.

[HerrAugust]

@jusjak11 are we talking about TTgo watch V3 with microphone? Maybe we are considering different versions of the watch...

[jusjak11]

@HerrAugust Mine is TTGO 2020 V2 with GPS. If anybody reading this have the same version, please chime in with battery duration and settings.

[Crsarmv7l]

@jusjak11 You may just have a bad battery. My original battery held was rated for 380mA but the capacity was really only 240mA

Here is where the firmware sets up sleep @HerrAugust
https://github.com/sharandac/My-TTGO-Watch/blob/master/src/hardware/powermgm.cpp

[jusjak11]

@Crsarmv7l I measured consumption with ampermeter to be 80mA, so it is not the battery, the watch does not go to sleep for some reason. I did not analyze cpp file you attached. Does it go to sleep automatically after certain time or it has to be initialized.

[HerrAugust]

@Crsarmv7l thank you for the suggestion! However, this power settings are applied automatically? If not, could you explain how to enable them? I am charging my smartwatch to discover it anyways

@jusjak11 maybe there is a setting for disabling the GPS in the GUI...

[Crsarmv7l]

@HerrAugust yes the sleeps are applied automatically in sharandacs firmware, as is the wake timings. I like to play with the firmware to suit my needs.

Definitely turn of the Always On setting and see how it works for you, because it keeps it in a different sleep level which drains battery faster.

[jusjak11]

@HerrAugust All GPS settings: auto on, enable on standby, apps use gps, fake gps via ip are turn off. I also have in Battery setting: power save: on.

[Crsarmv7l]

@jusjak11 You have your gps always on with the "Enable on Standby." That keeps gps going all the time and will prevent your watch from fully sleeping and drain the battery faster

[jusjak11]

@Crsarmv7l No, that setting is off like all others related to GPS. I measured again through the power supply. Wit everything off including screen 64.3mA@3.8V, and 67.7mA@3.8V with power save = off. Something is preventing it to go to sleep, or it has a hardware failure.

[sharandac]

@jusjak11 simple take a closer look on the serial interface. Here you can see exactly which module blocks the standby mode.

What does it tell you?

[jusjak11]

As I can see it goes to light sleep and consumption is still 63mA. How is that possible? What is taking this 63mA?

[jusjak11]

I can see that consumption goes down to 33mA briefly and than back to 63mA, every minute, so it tries to go to sleep but something wakes it up again, which is not shown in the serial port.

[sharandac]

@jusjak11 It would be interesting to see the pmu.json.There, the Watch is set to wake up every minute when USB is connected. If USB is not connected, every 5 minutes. The Watch then goes back to sleep after the display timeout, default 15s. And by the way, it's a bad idea to measure the current when USB is connected, that takes round about 19mA extra. First, maybe try turning off "silence wakeup" and see if it gets better.

  "compute_percent": false,

}

[jusjak11]

@sharandac Where is pmu.json file? It doesn't seem i can find it. Sorry I am new in this.

[jusjak11]

Measured consumption again to verify this 5 minute timer. The consumption is, without USB connected, screen off, BLE off, WIFi off 63mA @ 3.8V and every 5 minutes it goes down to 33mA briefly and than back to 63mA, which means it does try to go to sleep but something prevents it, something which cannot be seen over the serial port. Notice that serial port is not connected so 19mA does not apply.

[sharandac]

It's starting to sound to me like we're chasing a phantom that doesn't exist. The measurement results are so contradictory that I doubt the measurement. We have seen on the serial interface that the Watch goes to sleep, i.e. saves power. Okay, that's done. The software is working properly. But if we interpret your measurement results, they say exactly the opposite. What does the measurement setup look like?

[jusjak11]

@sharandac You don't have to have any special measurement setup when the watch battery in normal use lasts 4 to 4.5 hours. So, if you have good battery you know that consumption is real. Than if you measure the current to be 63mA you know that the battery is good and watch really consumes it. The test setup is: watch is powered with power supply set to 3.8V, directly to input pins where battery is connected. Battery is disconnected. Ampermeter is in series to power supply. The USB cable is not connected, thus serial communication is not monitored (the reason is I don't want to have double supply: from USB and battery input). In bootup time consumption goes to 110mA. After bootup, with screen on : 85mA. After default 15s screen goes off: 63mA. After 5min. there is a glitch: consumption goes briefly to 33ma and right after it back to 66mA. And this repeats every 5 minutes.

When watch powered from USB I do not measure current because I did not make split cable to connect ampermeter but monitor serial port. It behaves different than on battery supply. For some reason, sometimes it goes to sleep mode and stays there for a minute and so on, but sometimes right after went to sleep something wakes it up right after it.

So I managed to recreate error here, but I do not know what is triggering it, and why sometimes it happens, simetimes not as shown on serial port. It looks like the reason is in type of power: USB or battery, and battery voltage, how it boots up. I am just giving some hints.

This is seen on serial port when watch is waken up right after going to sleep:

[sharandac]

The setup doesn't sound bad. What surprises me about the log files is the too short interval between standby and wakeup ... 4 seconds? So there must be another reason why the Watch wakes up again after such a short time. The setting is 1min. The interesting thing is that it doesn't go into silence wakeup but wakes up properly. Does this also happen if you only supply the clock via USB without a battery inserted?
