Good morning
I have a weird problem that I think no one has reported yet. It happened two or three times now and I didn't know why but after leaving my phone charging at night, when in the morning I picked it up I only had 1% battery left. The phone simply kept discharging during the night although plugged in and on the screen showing as being charging.
After a lot of thinking and luck, I am now able to replicate the problem but I have no idea of how to solve this.
It's quite simple, if there are any unread notifications (e-mail, sms, missed calls,etc) on the notifications bar, the phone will simply not charge even if it shows you that it is and will keep discharging.
My testing procedure was as follows:
With a remaining charge of 16%, I plugged the charger on the wall socket and immediately on the phone. The orange charging led turns on (I did not have unread notifications at this time) and after a couple of minutes I had a current battery charge of 27%. All good and normal.
From another phone, I've sent a test e-mail to the Xperia's P Gmail and the orange charging led turned off like it should, and in his place the blinking green one from notifications turned on.
I've waited a couple of minutes and when I checked the battery again to confirm my theory, I had already lost 1%, going from 27% to 26% clearly showing that the phone was discharging (although the screen icon was showing like it was charging up).
After confirming this, I've cleared up all notifications that were showing and the green blinking led went off giving place to the orange one once again, indicating that the phone was charging, except that it wasn't. It didn't resume charging even after wiping all notifications and I had to unplug it from the charger and plug it back in, for it to start charging once again.
I think this is a software related issue (possibly a kernel one?) but I do not have the knowledge to provide any sort of fix.
My only solution for the time being is to clear all notifications, set the phone to airplane mode and only afterwards plug in the charger to leave it charging properly, and making sure that it does not receive any sorts of notifications that might interrupt the charging process.
It would be nice if someone could also test this to check if it only happens with my device.
My phone is FULLY STOCK with the latest B.1.54 firmware and has been repaired/updated through SUS two times just to make sure all was done properly.
Please advise.
