回答“Nest Gen 2 Battery won't change low lin”Three weeks ago my Nest thermostat suddenly would go off line due to low batter voltage, I pull the thermostat off the base and charged with an external micro USB charger, it charged fine. I put the thermostat back onto the base, and within a few hours the battery voltage dropped again, causing the thermostat to go off line. After trying and getting the same result a few more times, I started focusing on the base as the source of the problem. I only did one thing to the base which has rectified the problem, what I did is depress the small spring loaded tab that holds each wire in place and making electrical connection, then move each wire back and forth a few times, as I suspect one of the wires was not making good electrical contact and causing the battery to not charging properly. This has fixed the problem 100% the past three weeks, the battery level is always at least 3.8 volts, where it would go down to 3.7 volts when it was disconnecting from my home network, it has not dropped off line even once...
回答“Apple logo then blue screen”I reloaded the iOS 10.1 through iTune 3 times, first time restoring the apps, music and photos to the phone via the backup, the BSOD returned, second time I loaded a few apps and music, the BSOD returned after a few hours, the third time I only loaded a couple of apps (Facebook and Messenger) and left the music and photos off, this time the phone has been 100% stable for 3 days without any unintended reboot or BSOD. I will monitor and load a couple more apps at a time then wait a few days to see if the phone remain stable, perhaps some part of the firmware was messed up which took 3 tries to clear up.
