Hi everyone!

I’ve been using my Unihertz Jelly Star as my main phone for more than 2 years and the original battery was starting to get weak, so I decided to replace it myself.

I made a full video tutorial showing:

• screen removal,
• motherboard removal,
• battery replacement,
• mistakes to avoid,
• and unfortunately… how I slightly damaged the rear LEDs 😅

Video:

The filming and editing are terrible, my English accent is even worse, but maybe this can help other Jelly Star users keep their phone alive a bit longer!

Good news:

• the replacement battery was an original Jelly 2 battery from Unihertz,
• everything works normally afterward,
• including the fingerprint reader,
• and I got my normal battery life back.

Feel free to ask questions if you want more details!
