I recently got a Kospet Optimus Pro and wanted to be able to use it for online tasks while on the go (checking email, weather, etc).
But I found that turning on BT internet tethering caused a large amount of battery drain on the watch, even when doing nothing else (around 45% in 8hrs).
I decided to look for a way to have tethering only activate when the display was on.
After a bit of searching I found a thread on XDA that showed how to do just that via tasker.
You need to install tasker and Bluetooth auto connect and then follow the instructions on the XDA thread to create tasker profiles to turn tether on and off.
I found it worked better on my watch with the initial wait time set to 5 seconds rather than 20 as suggested so that it is close to the backlight timeout.
After setting this up I only loose 13% over 8hrs (with the watch doing nothing else) and when I unlock the display BT tether auto-activates in a few seconds and I have internet access without the constant battery drain, or having to mess around in the BT menu.
I hope this helps others get better battery life from their watches
Good points but I would also consider that your phone has an 4 or 5Kmah battery vs a 400 to 600mah battery (average) in your watch.
Plus you can charge your phone on the go while your watch is less mobile. A hotspot still requires a password to use it.
id love to implement this battery saving solution, although i would need to get my watch to Bluetooth internet tether properly first.
when using the phone under Bluetooth internet access i click the âinternet accessâ toggle but get âcant use bluetooth tethering while connected to wifi networkâ. then i turn wifi off on the phone, but when the same toggle is clicked on, it immediately turns itself off with no error, no internet.
from the watch i navigate to settings > connect > bluetooth > paried devices > select my phone > system cog wheel > doesnt even have an internet sharing option to click???

Thatâs odd. You should have an âInternet Accessâ checkbox on the watch in the bluetooth menu (where you described). It should be just above the âContact Sharingâ tick box.
You may need to enable BT tethering on the phone first. Have a look on the phone under settings > more settings > bluetooth tethering.
If that doesnât help Iâd try un-pairing and re-pairing the BT connection.
i appreciate your help, i was wondering why i see the option there on my phone and click it on, but it simply wont stay active.
I will try to un-pair and re-pair the phone and watch together, but also âforgetâ the connection and start again from scratch, gonna give it a try now.
iâve tried every possible combination i know of. still no success.
phone wont let me enable BT internet tether (even though the toggle is there)
watch wont let me even see an âinternet accessâ checkbox under BT menu
My Samsung S7 Active is the same way. It is there but wonât let me activate it. I wonder if it is a carrier based issue. AT&T places several restrictions on their Unlimited Data plans. This may be another one.
i hope thatâs not the case although i wouldnât put it past the carriers to implement something like that, they do alot of those cheeky moves up here in Canada with our carriers as well.
Itâs too bad Canadian Mobile companies canât supply the price and data that Australian mobile phone companies give, For $65/month you get 125GB of data at max speed 4G/LTE then it gets capped. But here in Canada, you get 10GB of data at max speed and then throttled for $75/month. but thatâs a whole other corporate monopoly issue.
in regards to the BT internet tether, i will keep trying things. for anyone else experiencing the same problem feel free to post here and keep the thread alive until we find a viable solution. could just be something simple that we are neglecting.
Did you go into settings > more settings > bluetooth tethering (on the phone, not the watch) and enable it there before you tried to enable it via the BT menu on the watch?
I have found that if I donât do that, when I enable âinternet accessâ on the watch it immediately turns off again.
thanks for your attention, i will continue to research cause.
for quick workaround there is always wifi hotspot although much more considerable battery drain vs low power bluetooth. BT would be all day solution, wifi is recommended to toggle on and off, or pop in SIM card.
Sorry if this is restating stuff you already know but I was just re-reading this thread and there was something that Iâm not sure was entirely clear.
When you go into the BT menu on the phone and select the smartwatch and then tick the âinternet accessâ checkbox, what the phone is trying to do is get itâs internet from the watch, this is not what we want to do. Thatâs why it complains about you already being connected to a WiFi network.
The âinternet accessâ tick box needs to be checked on the watch, not the phone.
Again, sorry if you had already realised this, but I figured better safe than sorry and it canât hurt for it to be in here twice for anyone else reading the thread with similar issues.
unfortunately i havenât been able to troubleshoot this, but i have utilized a workaround.
i keep the watch connected 24/7 using watchdroid over BT for all incoming/replying notifications, then i installed MacroDroid and customized a macro to enable WIFI upon screen turning on and disable when screen turns off. (which helps immensely keep battery consumption low opposed to always on wifi)
works perfectly, turn the screen on via HW button to view the time while wifi enables in the background and within 1-2 seconds i can still trigger google assistant using only my voice or tap to refresh weather (using smart touch floater) or make free unlimited wifi phone calls via Hangouts or wifi video calls via DUO. then turn screen off and voila wifi disables.
as mentioned above in earlier posts the issue still may be due to carrier or handset. i have a midrange galaxy A5 (soon to possibly upgrade to LG G8x dual screen, hopefully it will work as that is a flagship handset).
