It's no secret that the main constant consumers of battery charge are screen and cellular communication. If everything is clear with the screen, then you can still solve the problem with networks. The thing is that the default android is looking for all the networks that exist in the world, while significantly burning the battery during unnecessary search. This search can be disabled (if more precisely, cut to the desired minimum) in the engineering menu.
More details:
The cellular communication system is designed so that the mobile phone is constantly looking for a "best option" - it continuously scans the radio fleet, finds a cellular station ("tower"), communicates with them, analyzes the signal strength of each station, and switches to the station with the best parameters. An ordinary GSM phone can work on 4 radio frequencies collected in two pairs: "900mhz + 1800mhz" and "850mhz + 1900mhz". The first pair is allowed for use in Europe (including Russia), the second pair is used for example in America. When settings by default GSM, the phone constantly scans all 4 radio frequencies in search of a signal from cellular stations. But for example, in Russia at the frequencies "850mhz + 1900mhz" no cellular radio signal and will not (they are used / reserved for other purposes), and precious electricity to analyze these frequencies - is spent literally wasted.
1. We enter the engineering menu by typing in the phone
*#*#3646633#*#* or through any program (MTK Engineering Mode, for example, is in Google Play)
2. Go to
MTK Settings in the tab
Telephony open up
Bandmode 3. Select an active SIM card
4. Now we remove the checkboxes from the frequencies that are not active in our region (Russia, Europe) "GSM850"
"PCS1900",
"WCDMA-800",
"WCDMA-CLR-850",
"WCDMA-PCS-1900",
Confirm the changes - click the button
Set Reboot your phone!
Now the phone will not scan these frequencies, respectively, the operation time will increase significantly.
Attention! After turning off the frequencies, restart the phone and check the data mobile data! If you disappear 3G (there will be only an E icon) - Return to the menu and turn on the last three networks sequentially, checking the network icon change. Some telecom operators in different regions of Russia are tied to data transfer.
I recommend also to check for every case the workability of calls and send SMS. LTE settings do not need to touch - I have a tick opposite Band 1, 3, 7, 20, 40, everything works fine.
I will lay out your screenshot for example:
A warning! Do not touch anything in other settings in the engineering menu! Even the slightest change can lead the phone modules or the phone itself in a non-working condition! Follow the strictly this instruction and do everything only at your own risk! If not confident in your actions - better leave everything as it is! To restore the factory settings, click
