    • Rimuovi le due viti Torx T2 posizionate sul fondo, vicino alla porta micro USB del dispositivo.

    • Se lo schermo è crepato, puoi applicare del nastro adesivo sul pannello per proteggere gli occhi dalle schegge di vetro e per avere una migliore presa per aprire il telefono.

    Torx 2 also works :)

    Tried pentalobe drivers but had to get a Torx 2 in the end, possibly some variation across regional models.

    Pentalobe screws on my p8…

    In the kit,i have only T2…

    joska Horvath -

    T3 works best, T2 doesn’t cling to the screws too well

Really helpful guide. Only hiccup was that on my handset the screws holding the casing together (Step 2) were Torx 2 rather than pentalobe, possibly a regional variation. I opted not to remove the loudspeaker (Step 10) as the ribbon cable was firmly stuck down and I worried it would break. This meant I could only cleanly remove the adhesive pad in line with the charging port. I was able to prise out the battery using spudger and screwdriver to scrape the other pad from the phone body. All now reassembled and working properly!

Overall a very helpful guide . I also had torx screws in mine . The torx screws are tiny , so make sure you have the right screwdriver before starting . We didn’t bother removing the loudspeader assembly either (Step 10) . You can just prise up the ribbon cable (carefully) . Add heat if necessary . Now to the biggest problem . Removing the old battery from the phone . What a nightmare ! It’s really stuck down .We took our time using a hairdryer (no heat gun) , and a flat head screwdriver , and went from one end to the other prising it off gently . It still took about 20 minutes . Saying that . Don’t rush it , as it’s the final stage . Also . If you do use a flat head screwdriver then don’t twist it , as you might damage the casing . Just slide it underneath it applying heat . Total time to remove the old battery was 90 minutes , but about 50 of those were spent just getting the first 2 screws out . 20 minutes to put the new battery in and reassemble . Make sure all flex connectors are properly reseated .

My P8 battery has completely died on me. I cannot believe that to replace a battery, we have to now go to these lengths to do it. There must be a mountain of mobile phones, where the only issue with them is a flat battery. Surely, this cannot be allowed to continue. I know why the manufacturers want to make it hard to simply replace a battery, because it sells more mobile phones. But think of all that wasted technology, where a phone may have lasted just over a 24 month contract before the battery is done.

Many thanks for this tutorial. Together we shall beat them!

Thank you for a very nice and easy to follow tutorial!

I have now replaced my battery with what should be an original battery for the Huawei Ascend P8, battery nr: HB3447A9EBW. For some reason the width of the new battery is a few millimeters smaller than the old one, meaning that it does not fill out the space completely. Has anyone else experienced the same?

After having assembled the phone again I experience some weird issues with the battery level dropping from 50%, 60%, 70% or even 100% in an instant. I have tried calibrating the battery by, letting it die completely, recharge it to 100% let it drain completely again and recharge. I have tried different battery calibration apps and a factory reset - nothing helps.

I contacted the company I bought the battery from and got a replacement - still same issue.

Unfortunately i damaged the original battery when taking it out, so i cant use that as a reference.

Any suggestions would be most appreciated!

Most likely you’ve got a fake battery… :( A telling thing can be if the serial does not match the one you can read from the QR code beside it. Only solution would be to get a genuine one. I can feel your pain.

I have the same issue… I open the back cover and unplug the battery flex connector and then reconnect it again… it is OK for some time but when flex connector is loose again… I grtget the same problem… InIn my case… The battery bracket holding the plug tight is lost and hence connection losen after some time… I smam thing to cut a bracket from a Pepsi Cane…

Great tutorial. Unfortunately the glue stripes were too sticky. Don’t know what Huawei intends to do with such strong stripes. After 30 minutes I could remove them step by step.
