The Nexus 5 was produced a while ago, more than 4 years!
But this phone is still fast and I'm using it as my daily device. But there was one problem, the battery!
If you want to replace it you still get an (if you're lucky) an original used battery. If you're unlucky it's a fake one or it was just lying around, loosing all capacity and is at least as bad as the battery you already have.

In 2013/2014 a lot of people managed to press an Lg G2 battery inside the nexus, the BL-T7
BUT this phone and it's battery is very old, like the nexus 5

I tried the BL-T7 Mod, after receiving a lot of fake batterys, I finally got an original one, but yeah, still a 3 years old battery, that was lying around - so it was not good at all, and I lost NFC and Wireless charging

Here is what I got for you:

On Ebay, I was looking for a new phone (because of bad battery life) and I found a perfectly fine looking Nexus 5x for 20€, the seller said it won't turn on. I ordered it and i did not manage to repair it, the seller just lied, bc he didn't say it was damaged by water
What I did: I saw the battery, thought about, "hey this is a 2016 battery, original and it may fit"
I ripped it out and really managed to swap this 2700mAh BL-T19 battery with my Lg G2 3000mah BL-T7 battery that was inside my nexus

And holy, THIS BATTERY LIFE! - 5hours SOT under heavy load!: https://imgur.com/a/sOdT0

https://imgur.com/a/x2kXO min brightness, not doing much (only whatsapp), I know that is unrealistic, but at least, it's achievable!!


Benefits:
it's a new Battery (produced in 2015/2016)
NFC working!
Wireless charging working!
The nexus 5x had a lot of problems, a lot of dead phones, and if you're lucky you can buy a defective phone (like me) and get a fully functional battery!!

################################################## ###########################

NOTE: Use Tape, this is a powerful battery, if the wires touch each other, it may start burning
I won't take any responsibility if your phone get's destroyed!

################################################## ###########################

How I did this:

this is a BL-T19: click
and this is the one in the nexus 5 (BL-T9): click

as you can see, the nexus 5x's is longer, but it's the same width. It's longer than the lg g2's one so i had to make space

I won't make pictures of my mod because i already did it, closed my phone and I really don't want to reopen it

1. Completely disassemble your phone, you need to remove metal from the frame
2. Search a dremel to make space: I have no dremel so I used a DC motor and put sandpaper with zip ties on it (https://imgur.com/a/O7SIU)
3. Now remove metal from the frame, I have here some pictures on my testing phone frame: https://imgur.com/a/53tbX
4. Replace the battery! Do it exacly like here: https://imgur.com/a/Yj7ww
I won't decribe it any further, you may ask for help here or in older threads (Lgg2 battery replacement)
5. Here are some other Pictures I edited for you, the 2nd and third are the important ones! https://imgur.com/a/lpz8W
here are Pics of my mod: https://imgur.com/a/8BLVj

6. You're done! try to bootup, close the phone, and be happy about a big battery NFC and Wireless charging!!!
Note that you may have to remove some plastic from the cover that goes onto the mainboard,

Will report tomorrow after a full day usage because for now i'm gonna load it overnight

Okay my test results are here!

My display brightness was maxed out most of the time.
5h Sot for an intensive workload is very impressive! I tried everything except gaming to stress the hell out of that battery, and it lasted so long!

I'm gonna test a normal workload and upload pictures here if you want.

.... That seems a little crazy for a battery that has only 400mAh higher capacity than the original 2300.. so.. a 20% boost?

Well, I undervolted and my screen was on low brightness
But my core clock is at 2.35Ghz

It was not a worst case, but it's real

and it's not only 20%, because the original battery is veeery old, you are very lucky if you get one with more than 1700mah left

I doubt any of us were getting 5-6 hours SOT even 4 years ago.. maybe, though. It has been a long time. I'm not doubting you, just wondering out loud how that works out since the math sounds weird.

Mostly it's because I really tried to get the best Sot, with using it not much. So my phone was a long time on my desk with whatsapp open, and I was only texting.
That's no usual usage, my usual usage was 7 hours Sot, still impressive
