After Being Talked Out of It Once by After-Sales, I Finally Replaced the Battery Anyway, and the Old LCD Flagship Is Fully Revived

Preface

Last week was really busy, so I didn’t even update the “A Week in the Life of an Indie Developer” series.

In the blink of an eye it’s already December, and 2025 is almost over 🤣. I hope I can push the project forward a bit more this week, so I’ll have more results to look back on in the year-end recap.

Back to the topic: last month I went to vivo after-sales for the first time and didn’t get the battery replaced—they only downgraded the system. The after-sales staff said replacing the battery wouldn’t improve battery life, that my iQOO neo5 Vitality Edition had hardware aging, blah blah~

Later, after reading a lot of comments from other users, I realized this was the standard after-sales script, and I’d actually been taken in 😂

So last week I went to after-sales again. This time, no matter how much the staff repeated themselves, I insisted on replacing the battery, and I finally got it replaced successfully.

After-Sales

A lot of the shops in the mall where vivo is located have been emptied out

Replacing the Battery

The after-sales staff is carefully replacing the battery

The last time I took apart a phone myself was many years ago in secondary school. Phones and tablets back then were easy to disassemble, and I even replaced screens and batteries myself.

Most phones now have a mid-frame, so disassembly is more complicated.

I watched the battery replacement process and felt like I could probably do it myself too 🤣

• Heat the phone with a heat gun
• Pry open the back cover with a plastic pick
• Clean off the dried adhesive residue with an electric screwdriver
• Remove the SIM tray
• Remove the mid-frame
• Replace the battery
• Put it back together
• Apply adhesive
• Place it under a machine for a few minutes (I think it’s waiting for the glue to cure)

Results

The effect of replacing the battery was immediate

With dual SIM dual standby and 5G turned off, after a full charge, I’d used it for nearly 13 hours and still had 76% battery left 🤣

Now I’m charging it once every two days.

And the after-sales staff had even tried to convince me that replacing it wouldn’t improve battery life 🤣……

Wrap-up

You can no longer buy a new LCD phone with better performance than the iQOO neo5 Vitality Edition.

After this battery replacement, I feel like it can last another three years 😄

I’m no longer afraid of manufacturers only making low-end LCD phones 😁
