Battery replacement for Japanese rice cookers

The battery in some Japanese rice cookers will run out in about 10 years. Unfortunately this battery is solder-on and thus not replaceable by the user. Therefore I had to desolder the old battery and mount a 2-AAA battery holder. From now on, the two AAA batteries should last forever. If they somehow will run out again, it is very easy to replace.

Two big problems with Le S3

Encountered two big issues with the Le S3:

1) No broadcast, apps are not aware of network changes, such as register loss of SIP after switching from WiFi to mobile data or vice versa.

2) No setExactAndAllowWhileIdle(), apps cannot do things periodically, such as register of SIP every 15 minutes.

The result is: communication-based apps become totally unreliable. Seems a general issue of such Chinese phones.

[Solution] Install the unofficial LOS 13.
