Unfortunately the V20 is the last LG flagship to carry a removable battery. The current V30 has a sealed one and there are no signs that LG will do otherwise for the V40
I have the V30+
Nice to have 128GB internal storage, wireless charging & distortion free wide angle camera.
Battery life is pretty good.
The phone feels very good in the hands.
If you click on the Compatibility tab from the link you provided & go to LG, you will find the V30.
Some questions about the charger:
Does it heats the phone?
How fast does it charge?
Thanks
Well, you look at the battery gauge in the Task bar. If it drops below 30%, you place the phone on the wireless charger. If it reaches 80% to take it off.
One thing you can do is to charge the phone via a timer socket. You can set the timer to say one hour and charging will stop after that time. By practice you will know what time to set for the battery to get 80 or 90% charge.
