LG G Pad X 8.0 Bootloops When ~30% Battery - LG G Pad X 8.0 Questions & Answers

Wondering if this is a common issue with these.
I got this tablet for my son during the first "Tablet On Us" promotion last year and it's a piece of junk. He's had issues with it basically within a few months of getting it. The biggest one is it reboots and goes into a bootloop once it gets to around 30% battery. I'm assuming the battery % is actually reading way off, hence the battery is dead or about dead even though it reads 30%.
Is there something I can try? Flash a custom rom? Factory reset?
Thanks.

It's clearly a battery problem. I had same issue with my OPO. Just replace your battery

If its still under warranty, change it. I changed two (son and daughter ones) already. and i think my wife's one is starting to do it as well.. always happens at 30%. The device is great except for this damn battery thing.
if you got it thru t-mobile I bet it still under warranty. call them. or call lg.. But i think t-mobile is the better option. They order a new one for you and send it to your local store. you'll go and pay $20 for the exchange fee. If you go thru LG, the warranty should be in effect but you have to send the tablet in.. and wait.. at least with tmobile direction, you get a tablet right away. I rather pay the extra few bucks and get one right away. shipping to LG maybe $8-10?

Sorry, completely missed that you replied. I think I'm going to give that a try. Replacement batteries are $80 on eBay, not worth my normal DIY at that point.
I'll see what T-Mobile says. Glad I'm not the only one with the issue.

Bro today i tried readback utility and its failed.
But it worked with k3note. Also worked for lenovo A7000+ and successfully fetched recovery.img for both devices
Mtk drivers installed properly. But dont know where it went wrong?
I think oppo managed not to respond while power off.
And also i searched that oppo will fully prevented fastboot services since 2016

So all ptovided resources brought Nill out come for my device.
Started hating my device.
And specially thanking for ur efforts made. And also for the time and patience u invested.

Anyone know of a compatible battery for these? Batteries are $80 on eBay and can't find them "for parts" cheap either. Curious if you can take another similar sized battery and just splices the wires.

just wanted to chime in that I am also suffering from this. Had these issues for the past 6 months and sadly missed the warranty period.
I had to fall back on my 5 year old samsung tablet for my son.
I used to work in wireless and my experience lead me to the phrase, "LG, Lucky if its Good.
I broke from this belief to give them a shot years later only to find nothing has changed with their quality.

I know I'm almost two months late to this post, I haven't logged on here in a while. Do you happen to have a link?

I got the one from Amazon about two weeks ago and replaced it with great success! No more boot loop and normal charge and battery functionality. I think it was like 22$
