I always feel that my Xiaomi 10 phone's battery is not durable, needing to be charged 3-4 times a day. Although the original 27W charger is fast, it drains quickly. After one outing, I decided to replace the battery of my Xiaomi 10 phone. I searched on Taobao and found a store that specializes in selling Xiaomi batteries. After asking a few questions, I made a purchase. After waiting for two days, the package arrived. I opened the package and checked it; there didn't seem to be anything unusual. It looked like it came from Xiaomi's after-sales service, and I couldn't see any differences.
In August, the failure has already become a joke Young people's first Taobao failure, the following content is about my pitfalls.
Replacement#
In the package, besides the battery, there was B7000 glue, battery adhesive, several disassembly tools, and the battery's anti-static bag seemed to have been sealed after inspection. Is this how it came?
After turning off the phone, I removed the SIM card tray (
The battery itself did not show any obvious differences from the original battery, such as different fonts and inconsistent font sizes.
After heating the back cover, I gently pried open the larger gaps of the back cover. Here, it was at the camera and infrared position. I slowly cut open the inner sealing glue along the gap, then used a prying tool to hold the gap while prying up the other side. I saw the white glue that the prying tool exposed, which made me quite anxious because I bought a second-hand phone, and I had never seen white sealing glue when I disassembled Xiaomi phones before.
Here I messed up; I was too eager, and the prying tool broke at the camera's stress point.
After opening, I could see the NFC and wireless charging coil's heat dissipation??, and by tearing along the mainboard, I could see the screws for the left and right speakers.
Holding the shielding cover with one hand, I pried up the battery connector to cut off the power; here, I accidentally pulled out the speaker's btb.
Following the battery's instructions, I removed the battery; first, I tore off A and B, then pulled up A. The battery came out easily. After removing it, I peeled off the pull-tab? and the battery sticker on the battery frame.
I aligned the new battery in place and connected the battery connector's btb, simply secured the mainboard shielding cover and NFC wireless charging coil, and powered on for testing. (I didn't apply the provided battery adhesive here.)
After powering on, it showed 50% battery, and I tested the speaker, wireless charging NFC, vibration, and wired 27W fast charging; I created a shortcut to check the battery life, and the remaining battery's actual capacity was normal.
The battery life is built into MIUI13, somewhat like AccuBattery)))
This has been used for half a month, and it doesn't seem too accurate...
In fact, it has gone from charging three times a day to two times a day, and it feels more reassuring to use, for reference only.
Then I turned off the phone to check if there was anything I hadn't connected before installing the shielding cover. Don't apply too much force to achieve miracles~ Don't ask me how I know this.
After slightly adjusting the NFC coil, I installed the back cover. Since the back cover broke, I didn't apply glue for easier replacement later. Even without glue, the gap wasn't too large and was similar to before disassembly.
Unfortunately, the cover broke this time; I'm feeling sad.
