Battery drain while OFF!

OK so how weird is it that my X1 drinks its battery dry even while OFF?! I'd be happy to put it down to a dead battery, if it weren't for the fact that I have two batteries: one (>2 years old) OEM and one (~1 year old) 3rd party clone.
It's possible that both batteries are dying and not holding their charge. Thing is, I don't want to fork out on a new battery if the X1 itself is faulty.
Any thoughts before I send my X1 off to silicon heaven?

A little power has to be drained to keep the clock running. But my phone drains a lot if its off..but it fell into water so it doenst really count as normal behavior..

How much of power is drained? 1-2%? Or 50%? Also, sometime when you restart phone it shows that batt has 10-20% less power than before restart.
2 years for batt is quite a lot, and we all know that 3rd party equipment is not good as original. So maybe is batt dead.

Has anyone replaced the battery on their note5 yet?

I'm not satisfied with the performance of my battery. I tried everything from greenify to factory reset. I think its time to replace the battery of my note5. Has anyone replaced their battery? What was the cost? And how should i make sure I am getting the original battery from the service center. I am in india so if anyone has replaced the bettery of s6, note5, s7 etc please let me know

I replaced my n5's battery in RMA service. No cost

I've replaced my note 5 battery a couple times... not too hard. You will may or may not crack the back glass when pulling it off of device... ymmv.
You basically just take a blow dryer, heat he back, peal glass back off, unscrew like 15 little screws, push phone guts and screen out of metal outer shell, remove old battery and ribbon connector (old battery may be glued in), replace battery, put guts and screen back in metal shell, replaces screw, put back glass back on.
All said in done, back glass cost me $10, and battery was about the same, so $20 in total to swap. I've done a couple times now, can prob do it in under 5 minutes. First time took me almost 30... godspeed

cool, i am into electronics and i have all the tools to do it, just wanted to know if it is worth doing ourselves or going to the official service center. how is the after market battery performing? is it supporting the quick charge?

Has anyone replaced the v40 battery or had it replaced?

I remember when first run there was a system message that said don't attempt to remove battery. I think it's because battery is glued on and removal may cause damage to phone or injury to person.
Has anyone replaced the battery or had it replaced? What was your experience?
Thanks

Yes. Just did it on a v40 that I bought used on ebay. Battery had over 600 cycles and Accubatt was showing around 80% capacity.
Bought a new battery off of ebay for $12. Looked OEM except didnt have LG logo. Accubatt now shows 101% capacity.
Its really not that hard to replace. There are a few videos online that show how to disassemble the back. I was carefull and even reused the adhesive on the back cover, although i dont think id put it underwater anymore.

Battery replacement. Anyone has done it?

I'm unhappy with my battery life. While it did work 2-3 days with 4-5h SoT at best before I now get around 25-35% in the evening. Not suitable for another day.
So either the battery is done for or the software has become way way worse.

Battery Replacement does seem possible. So has anyone done it? Did it help?

Yes. I have done a complete screen replacement as well as the battery. I didn't need to watch out for a screen as it were completely destroyed. Yup, you're right about the battery, probably it needs to be replaced. I have a neat trick to help you with screen removal. Take a plastic bottle, cut a small rectangle from it (around 4x6cm should be enough) and then round those sharp corners with some scissors so there won't be any sharp edges left. Once you've that done, take your freshly cut plastic card and insert it into bottom gap (where speaker is). You could use a suction cup to raise the glass a little bit. And slice the adhesive around the screen. Ofc be careful not to push it too far to not damage screen ribbon. Watching teardown videos is crucial as you don't wanna pierce or rip apart the screen ribbon. if you want more information about this, feel free to ask As putting everything together - I recommend buying original lcd adhesive for xz2, it's simple and the screen stays on as well as original.

*#*#7378423#*#* go into this service menu then the battery health test, it tells you current max. capacity and health status whether if you need to replace or not.
battery replacement should be relatively easy since it is held down by screws not adhesive, be careful when opening up the phone you may damage the LCD also make sure you clean all the left adhesive residue before applying the new sticker or B7000 glue to the frame

I don't trust those numbers. That's the Problem here...
@Verity.
Did you realize any difference in Battery life before and after the change?

Certainly. I bought used battery as it was cheap and as the old one was quite worrying on the outside. I immediately noticed the difference (especially in sot) so with the new battery you should feel the difference even more.

Not sure if the degradation of the battery is good or bad...
After fully charging now:
And one of the earliest from 2018

That's pretty normal. Every battery has a lifespan. It's depended on temperature, usage but the most important factor is the charging cycles. After x cycles battery loses it's capacity. It's due to chemical reactions inside of it and there's nothing you could do about it. Until solid state batteries will come out, you will have to change the battery once 2-3 years.

So yeah....
I've done it and i'm not happy

Google warranty and battery

Hello!
I noticed that the battery in my Pixel 5 is definitely weaker than at the beginning, which is understandable because the phone has been used since new (for a year). I'm thinking about replacing the battery, but I'm curious if the Google warranty covers battery replacement based on the warranty? Free of charge?
My previous phone was OnePlus 7 Pro and during the two-year warranty the battery was replaced twice under warranty, once at the very end of it and I'm wondering how it is with Pixels

Battery replacement in the case of normal wear is not covered. They'll only replace a battery that has a defect. Lithium batteries naturally "wear" as they are used; with each charge/discharge cycle, the battery's capacity becomes a little lower.
