Semuanya dimulai sekitar tiga bulan lalu ketika port pengisian USB HTC One (M8) saya mati. Pada awalnya port kadang-kadang tidak berfungsi, Anda hanya perlu memindahkan sedikit kabel agar bisa diisi dayanya, kemudian Anda harus menahan kabelnya agar tetap terisi daya, dan akhirnya perangkat tidak akan mengisi daya sama sekali.
Hal yang persis sama terjadi pada HTC Vivid saya. Ketika saya memperbaiki Vivid, teknisi mengatakan itu adalah kerusakan air.
Bagaimanapun, setelah bengkel telepon lokal berhasil menginstal port USB baru pada telepon One saya, gagal pada percobaan pertama karena masih dalam kondisi yang sama, semuanya baik-baik saja. Untuk beberapa minggu. Kemudian ponsel mulai mati seolah-olah tidak ada baterai yang tersisa, sebesar 20%. Saya segera memasangnya ke pengisi daya, menyalakannya kembali, dan telepon membaca 1%.
Sudah melakukan itu sejak itu. Beberapa hari turun menjadi 0%, beberapa hari turun menjadi 20% atau 25% dan mati.
Berikut screenshot dari apa yang sedang terjadi.
Di bawah pengaturan perangkat, dikatakan bahwa kondisi baterai baik.
Jadi saya hanya ingin tahu mengapa ponsel saya melakukan ini, dan menurut Anda pilihan terbaik untuk memperbaikinya.
Saya mencoba kalibrasi ulang baterai, membersihkan cache, dan menginstal ROM baru. Tidak satu pun di atas yang berfungsi.
Jawaban:
There could be three reasons to this (not in any order) :
Battery lived it's life.
Fuel Guage drivers corrupted. To rule this out, i suggest back up your data and with your recovery wipe clean all Cache and system and flash stock(not sure if you cleaned fully when you flashed a ROM) If the problem continues, it is likely that it is not a driver corruption issue.
Hardware of battery charging chip gone bad. One possible way of checking this is to see if it is charging and discharging fully in safe mode. If it does unlikely to be hardware issue
I would recommend step 2 first and then if possible borrow a battery to check if it is a case of battery end of life.
All the best and do post the conclusion

Actually, after hours of scouring the forums, I finally contacted HTC via chat. Right away, they said to power off the device. Then hold the volume down, volume up, and power buttons all at once for...3 mintes??
Yep. You hold all three physical buttons for a full 3 minutes. He said this resets the battery logic, and how the battery talks to the software to let it know how much power it has based on the voltage. The phone started up, then shut back down. Powered up, then shut back down again for the whole 3 minutes, then I let go. It started turning on and when it finished, the battery read out 19%. Woah, before I did this, I was at 54%! Was my phone really that inaccurate the whole time? Probably. I'm charging the phone back up right now, so hopefully this fixes the problem!

I had the battery problem with my phone - shutting off at 20% and some settings resetting after charging and turning it back. Nothing helped except factory reset. The reason for such behavior seem to be HTC Service Pack (not 100% sure though). Make sure not to install it after reset or uninstalling the update might also help.

In case more people are having this issue but are unable to get the battery working properly, I developed a workaround that shows a low battery warning at any given battery percentage.
