My GPS shuts itself down after 15-20min, why?
[IMPORTANT MESSAGE GPS - HUAWEI & HONOR: DO NOT LOCK YOUR PHONE WHEN RECORDING A GPS SESSION]
Indeed, an issue with the GPS function can occur with Huawei and Honor phone.
These two manufacturers have a security system set up for when the GPS is being used by applications. Since it uses a lot of battery power, applications using GPS data are automatically shut down when the phone is put in sleeping mode.
As a result, the GPS is turned off by itself after 15-20min. The velocity curve is also impacted and is cut clean at the end of this same duration.
Unfortunately we do not have our hands on it and we can not get around this issue. Many applications seem to encounter this same issue.
We are well aware that this is an inconvenient, but unfortunately we are completely powerless against these manufacturing rules.
