Riddle me this, TAB(let)MAN....

[Buzz]

We have several tablets, accumulated from over the tablet years, and all but one, an LG 8" android tablet, are pretty miserly with the power when a browser is open, but moved to the background before sleeping. The LG is low power drain when other apps are backgrounded while sleeping, it's just the browsers (Chrome & FF) that suck down the power while napping.

Any ideas on what the cause of this behavior might be?

I'm used to leaving browsers in the background on the other devices (iOS, android, FireOS, and even ye olde WebOS on the HP TP), so when I knee-jerkingly do the same w/ the 8" LG, I get frustrated when I get back to the LG after just a few hours of sleeping, and it needs to be jump started.
Thanks.

Sucking up your data takes its toll on the battery...
Is it running an older OS by any chance?

LG is running 7.0, but HP TouchPad is running much, much older WebOS from 2011. iPads are on iOS 12.x. Fire's are current. ZTE tab runs 7.1, as does 2nd HP TP, but it has its own issues, just not the browsers' sucking data issue while sleeping (AFAIK).

I was hoping it is some setting that is somehow different among the tablets that can be changed, but google fu has left me lame, and I haven't been able to find anything that jumps out. Secondary thought is that somehow the LG is just "sleeping different", but I can't find any settings relative to data sucking in browsers only while sleeping; but other background and sleeping apps don't suck data. With non-browser apps in background, LG can go for days on a full-ish charge, but slap a browser into the mix, it goes down to a few hours. FWIW, the Fire tablets seem to be the least affected; when they're sleeping, they're conked out real good. I do have Alexa set to sleep along with the tablet, so I don't keep her awake when the tablets are snoozing.

I wish I could help, but I’ve got nothing.
I only know that chrome is a resource hog, and that android is full of holes.
I actually love LG devices, but their software seems pretty intrusive to me.
