Yes, it’s possible to have radio signal without a SIM card, but you only can dial an emergency number. I have test it with several mobile phones. So to save battery the only way is to switch off all GSM radios, or turning on flight mode in case you are not going yo use a SIM card.
It looks like the watch keeps the connection with the last tower with flight mode on till you move out of range. After that it stops using the GSM radio as intended.
After 2 month of use, goodbye Kospet Optimus Pro - maximum 1-1.5 days battery life, overheating, some other bugs in measuring the number of steps and heart rate monitor, welcome to HUAWEI WATCH GT 2. For 3 days the battery from 100% dropped to only 81% with a lot time active display and scrolling through menus, listening to music 1-2 times from the watch with a bluetooth headset, a few bluetooth phone calls.
Hmm, there are many thousands of satisfied users. I find your verdict a little premature after only 3 months, it would probably have helped if you had dealt with the matter a bit more.
It’s quality control.
As G says, on the whole people have been happy with their devices.
I was considering options but as you said - you have had the watch for 3 months and trying to return it after this amount of time is going to be extremely difficult to justify.
Hello Gianfranco.
I used your detailed Manual.
But when i have installed TWRP who is the way to comen into TWRP to ZIP Installation?
I dont know what button Kombo on my Kospet Optimusi have to push, to come in the TWRP Menue???
Please help me…
Thank you,
Greatings from Heiko
There’s no button combo in watches to boot into twrp, you either have to use adb (adb reboot recovery) or if you have root access then you could use any app from the play store to do that (if you have magisk then there’s an option there to boot to recovery)
Example - https://play.google.com/store/apps/details?id=com.awiserk.kundalias.rootboot
Hello.
i tested it with Adb reboot recovery and then my Kospet Optimus (2GB+16GB) shows
as result in small letters: NoCommand
Whats wrong.
I followed these steps:
SP Flash Tool - MT6739_Android_scatter.txt (from KW_C8_LFLT_TWRP) - Download only -
Download - And iam in “TWRP-MODUS”.
Here i pushed ZIP-Installation - TWRP-Patcher.zip - Install - Go
To come “out” of this TWRP i must do:
SP Flash Tool - „Kospet_OptimusLite__V2.5-Firmware" - “MT6739_Android_scatter.txt” - Download only - Download-Button - Go
