It has been a few weeks now, and the phone has been fantastic with the new port. Things are fast, stable and everything (expected) is working well.
A recent update partially fixed the battery ageing protection for me, but only partially. Is it working for any other users?
Here is a summary of what is happening for me:
Battery ageing protection set to 90%.
Phone charges normally up to the limit:
13:01:26 batt_soc:88 batt_current:334778
13:01:31 batt_soc:88 batt_current:1726075
13:02:17 batt_soc:89 batt_current:1700745
13:03:13 batt_soc:90 batt_current:1488953
MCE enables charging protection:
13:03:16 pm7250b_charger: smblib_somc_smart_set_suspend: voted for smart charging (1).
13:03:16 mcemodules/charging.c: mch_policy_set_charging_state(): mch_charging_state: allowed -> disabled
Charging stops correctly at 90%:
13:03:19 batt_soc:90 batt_current:0
13:10:59 batt_soc:90 batt_current:0
13:20:58 batt_soc:90 batt_current:0
13:30:01 batt_soc:90 batt_current:0
~31 minutes later charging resumes by itself.
No corresponding
mch_charging_state: disabled -> allowed
or
smblib_somc_smart_set_suspend: voted for smart charging (0)
appears in the log.
Charging begins again:
13:34:07 batt_soc:90 batt_current:483398 usb_current:1836395
13:34:12 batt_soc:90 batt_current:485229 usb_current:1844505
13:34:17 batt_soc:90 batt_current:485840 usb_current:1840285
13:34:22 batt_soc:90 batt_current:486755 usb_current:1889270
A few seconds later current increases significantly:
13:34:38 batt_soc:90 batt_current:1681214
13:34:43 batt_soc:90 batt_current:1645508
13:34:58 batt_soc:90 batt_current:1549988
Battery then charges beyond the configured limit:
13:35:13 batt_soc:91 batt_current:1488953
13:37:21 batt_soc:92 batt_current:1261597
13:39:29 batt_soc:93 batt_current:1123658
13:40:31 batt_soc:94 batt_current:1072083
Expected:
- Charging remains suspended at 90%.
Observed:
- MCE successfully disables charging at 90%.
- Battery current remains 0 for ~31 minutes.
- Charging resumes without any visible MCE state change.
- Battery continues charging past 90%.
I have tried 2 different chargers, and different cables. For some reason after ~30minutes, the phone restarts charging.
I am not sure what else to check or to monitor. If anyone has any ideas that would be great. I will try and look a little more in the next few days.
Thanks!
