Huawei Nexus 6P Battery Upgrade

I’ve had my Huawei Nexus 6P for about two years now. The combination of a great camera, an excellent screen, good performance and decent battery life has made this my best smartphone ever.

However, a couple of months ago something happened as the battery capacity appeared to have collapsed dramatically. Sometimes the phone would shut down only 5 hours after I had disconnected it from the AC charger when I left home, starting off supposedly fully charged! I had to always carry a USB battery and cable with me to not risk losing the use of my phone in the middle of the day.

Attempts to recalibrate the capacity indicator helped only insofar as the phone would shut down at 14% charge instead of say 55% charge, so there was slightly more warning, but the number of hours was still too short. This actually seems to be a common problem with the Nexus 6P, which otherwise is still a great phone.

It’s not uncommon for Li-ion batteries to significantly lose capacity after about about three years, but if it happens after less than two years as in my case, that’s not very good. Fortunately, replacement batteries are available and any competent phone repair shop will be happy to do the necessary surgery to replace a battery that is on its way out. Unfortunately the days when you could simply pop open the phone case without any tools and swap the battery yourself are long gone. This is a trend started by Apple and almost every other phone maker has since followed suit. I think it’s meant to get people to buy a new phone sooner, which is good for Apple and its competitors, but bad for consumers and for the planet.

There are Youtube videos that will show you how you how to open the Nexus 6P case and disassemble the phone to swap the battery. This involves the use of a hairdryer or heat gun to soften the glue that holds it all together as well as a plastic card and a small screw driver. As I did not feel adventurous enough to attempt this myself, I contacted several phone repair shops here in Tokyo. Repair King Japan replied. Though they they didn’t have the Nexus 6P battery in stock they were happy to order one for me. Once they got it, I dropped the phone off and two hours later I could have it back with a new battery. So far it’s looking good: It’s been 40 hours since the last full charge (with battery saver mode inactive) and it’s still showing 64% with about 3 days of power left 🙂

Hopefully with the new battery my Nexus 6P will be a great phone again for a few more years!
