How to reduce the power consumption of a smartphone in wifi hotspot mode?

Question

Android

I have an android smartphone. There was a need to keep the hotspot constantly on. However, even in idle mode, when no one is connected, the battery on the smartphone sags quite noticeably. How and by what means/tools can energy consumption be reduced? Through the developer mode or some kind of engineering menu? The very level of the wifi signal during distribution, I would also reduce it to 10%, I would know how ...

Answer 1

Perhaps this option will work.
You can share the Internet from your smartphone via Bluetooth, but this is a point-to-point connection. That is, according to this scheme, only one device can be connected to the Internet via a smartphone.

Answer 2

Look in the developer mode item "Networks". For example, I have a setting "Modem optimization at the hardware level".
PS Even if you reduce the power of the WiFi module, you need to look at the sensitivity of the receiver. This indicator directly affects the quality of communication, as well as power. Sensitivity, in simple terms, is an indicator at which a receiver can decipher a weak signal. If the sensitivity is low, then the receiver will simply not be able to read a relatively weak signal with noise. As a result, you will have to send the signal again. Here you also need to take into account noise, natural attenuation, as well as attenuation from obstacles. These include walls, metal structures, and mirrors that can completely dampen the signal.
PPS You are optimizing in the wrong place. Take a power bank or charge through an outlet.

Through the application settings, stop all unnecessary applications and services. Disable auto-updates. Disable bluetooth. Disable sim cards. It is also better to remove the memory card.
