Nest Thermostat Battery Low | How To Charge Your Nest
Вставка
- Опубліковано 5 лют 2025
- Your NEST thermostat might give you an indication that it is not getting charged and is low on power, or low battery or low charge indication. This is likely because your NEST thermostat has lost connection with your WIFI internet for some reason. I will show you some ideas on how to remedy this issue by trying a few common things. Perhaps try resetting your modem, or rebooting your NEST or resetting your furnace if you know how to safely do so. There are many causes, but if your NEST was installed correctly it should have an adequate charge to function properly.
Charge the display using a micro usb cable for about 2 -3 hours.
After charging, connect it back to the base and wait until it comes back on.
On the thermostat, go to Settings - Technical Info -Power. Make sure that battery level is at 3.8 V or higher.
Check that the display is properly connected to the base. If the display isn’t fully seated on the base, your thermostat won’t turn on and can’t charge its battery.
Check the wiring on your terminals, if you see a common wire that is not being used or connected, please try to connect it on the C terminal.
Your system may have a blown fuse. A blown fuse on your system’s control board can prevent power from reaching your thermostat. Contact a Nest Pro in your area to check your system and your thermostat wiring.
Try reinstalling your old thermostat. If your system works as it should with your old thermostat, your Nest thermostat may be damaged and needs to be replaced. Please write a comment below and remember to give a thumbs up or thumbs down. I want to know what my viewers like.

im 15 and my mom woldent let me try to fix it so aftyer 8 months of no ac i did it when shee was at work and i did it thanks to you thank you
Good job
8 months of no ac? Wtf
So glad you included the explanation about the device depleting the battery because it lost connectivity with the wifi. Explained my situation perfectly. Thank you!
Thanks for the video. For anyone wondering, the type of connector that is used for charging is a micro usb.
I used the cable from my Goggle chrome cast dongle to charge my nest 1st generation nest thermostat. I also have a dual range router with 5.0 and 2.4 gh bands. Nest runs on 2.4 only
Outstanding! Had to reset modem three days ago, didn't even think about the Nest, sure enough my battery was at 3.5!! volts, charging now and will reinstall after an hour or so. Thanks again.
To the point troubleshooting. Thanks 🙏 I recharge my nest battery and functioning normal, because of your great teaching. 🙏
Thanks for telling about the emergency charging port. Slept whole night with alarm beeping since I didn’t have the weird battery, but this saved the morning. ACTUAL LEGEND
Worked like a charm thanks! I glad I found you before I nearly destroyed my nest with instructions from another channel! 🎉
Thanks for this! I had recently upgraded my home network Orbi Mesh Routers. I used the same SSID and passwords, but forgot to reset my Nest (and my Ring Doorbell, and my Garage opener, and my August Door lock, and my Tesla Powerwall). Hence, the low battery issue. I discovered how to recharge the battery myself, but it was great to see you walk through the process which helped to ensure I was already on the right track. Thanks again!
Wow thank you so much! If I don’t watch your video I would go to buy a new battery. Now I know that the battery can be recharged.
Thank you didn't have to reset my internet, just had to take it off then put it back on and it reconnected and started charging! Thanks again for the video!
Wow amazing, my app was telling me that my nest was offline. Drained my battery in my nest. I reset my Internet and is starting working again. Thanks so much
Another pro tip here... if all this STILL doesn't fix your issue... press in and hold the thermostat while it is mounted to the wall until you see the screen change and a Google logo appear. You've just rebooted your nest thermostat.
That's exactly what google Nest support told me., which is similar to a laptop hard reset.
Thank you very much. My thermostat was offline, and the battery was low. I did a reset as you recommended, and now all is well.
Thanks. Had issues with my furnace the past few days and while the power was off to it the Nest had low battery, so it was helpful to realize we can charge it with a cable like that.
my wifi was not connecting to the nest during the night and that explains it wearing down the battery the next day.....recharged (micro usb) and good to go. Thanks for posting!
Watched your video and stayed till the end and found out I can charge it thru a charging in cable , hopefully it will work , THANKS
Thanks for telling me how to charge. my battery symbol shows zero bars it’s been charging for a half hour now. We’ll see what it is after an hour. Appreciate your video.
had a power surge and reset the modem and it corrected the issue. thank you so much for sharing this! you are the dopest dope. dopest dope.
We’ll have some coffee and think about things. 😂😂😂😂 Same bro. Same.
Thank you so much for this video! You just saved me from freezing to death!
I know this video is 3 years old, but there is a more permanent solution now. Basically the root of the problem is that with your current wiring, the Nest will only receive power (charge) while the fan is running. If your house is holding at a temp that doesn't need the fan to run, the battery will eventually drain. The permanent solution is to hook up the 24V Common wire to the furnace. It is indicated in the wiring backplate with a capital C. This wire will provide constant power.
Excellent information...thank you so much.
Thank you for this… your explanations were very clear and understandable and your tone of voice is very pleasant to listen to.
I do have one question though, last month we upgraded our home network. Not long after the Nest said it was offline, had no Wi-Fi and I got a low battery notification, but I had made sure it was connected to the new network, so I assume it lost the Wi-Fi connection at some point. It is connected to our network now and also to my Nest App, but it still shows a low battery in settings. How long does it take to charge back up once it’s connected to the internet again? It’s been about 3 weeks and still showing low battery. Do I still need to reset the power to my furnace in order for the battery connection to reconnect or just it just charge that slow after it’s reconnected to the network?
I had that happen once, and I connected it directly to a wall charger for a few hours and that took care of the problem. Good luck.
You are THE MAN thanks a lot for all your help 😁👍
Thank you so much for this video. Everything is back up and running thanks to your advice =)
My Nest remote was suddenly offline (it failed to reconnect to WIFI even after trying multiple times to no avail). It didn’t say low batter (it’s at 3.87 v).
Good to know it’s due to low battery. After charging (over 3.9v), now it’s back online automatically.
I have two nest thermostats. One is connected to the internet, the other not. Now the one not connected is not working (low (very low) battery. I have tried charging with the cable. I put it back, it appears that it is working then it goes in to shut down mode to try and recharge. Could this be the power unit of the a/c?
The battery is going dead because it is constantly trying to connect to the internet. Try charging it full directly and the put it near your router to get it to connect. Once that happens then it should work like a charm.
Thank you!!! Very helpful 😊
Thank you thank you!!!
Straight to the point coaching! Thank you 👍👍
Thanks for the great video! Very easy to understand and now charging our Nest thermostat as I type this comment. Now to the important question, is the dog OK? Warmer enough now? Thanks again!
I just confused your red wire is RH not RC?
Once we full charge Thermostat around 2-3 hours. How long battery should last?
6-7 months or do we need a C connector
It needs to be connected to a power wire for sure
Could the low power be a possible symptom of a bad transformer in the furnace?
If it is what kind of transformer is it and where can I find it in the furnace? Thank you
I am really not sure, but there is a low power connection from somewhere in our near the furnace. You might be able to have a service technician tell you over the phone how to test that wire, or perhaps it is a bad connection. Maybe contact customer support with NEST to ask for their free help.
Thanks a lot , helpful video !!
mine is doing this exact thing, had it a year and its the first time its done this
I want to know how do you completely power down the nest thermostat when it is off it's base?
I tried and there is no way to do it that I know of so I let the battery run out of power...which is risky because a totally dead battery sometimes will not accept a charge
@@FROSTYLIFE Press and hold the display for 10 seconds and it powers down when it's off its mount. The little light on it still blinks, but I can see that it loses Wi-Fi and disconnects from the temperature sensors.
I wish I knew this before the nest battery went completely dead. My screen went completely black and I can't get the settings or turn on the ac. Gonna try to see if I can charge mine like this. 🤞
How does yours get charged from the furnace without a c wire?
Thank you! It worked
Do you ever have to change the battery. When i walk by the nest it doesn't light up i have to press it to see the temperature.
there is a setting to make it "wake up" upon movement. The battery cannot be changed, but charges from your furnace power lead.
I lost power last night and it wouldnt connect said low batery.I charged it for 2 minutes put it back on and now working and connected
My battery will no longer take a charge. I've purchased a replacement. How do I change the 2.1Wh 3.7V battery?
You charged the Nest with a cord…..does the other side goes to outlet…..?
Thank you Sir
Thanks for the video
That was very helpful!....thank you and have a blessed day:)
Blessings to you as well
Come for the Nest Thermostat troubleshooting. Stay for the dog in the windbreaker :D :D :D
If I unplug my nest it lets me know about it straight away - stops working and I get a h72 code. 😭 would be so useful to have its own battery!?
This helped me with my issue.
Thanks Tom 😊💖
You are so welcome
Very helpful info. Just tried it and it worked. Thank you!
What if it's used on Manual like ours? It's summer now and the fan outside is only staying on for 15 seconds then shuts off. I'm charging the Nest to see if it helps. Any other suggestions?
Perhaps have a technician check your electrical on your air conditioning unit, sometimes electrical parts malfunction and need replacement.
Thanks!
You bet!
I have a programmable thermostat, not a nest, and I leave it on the same number all year round. I have never programmed it.
Did you leave it on "paradise" setting?
@@FROSTYLIFE I know, gzz whats wrong with these people not wanting a nest so they can save the world from going up in flames. Comfort, who needs comfort? Hassle, who cares, its worth it. Who knew you needed more then wifi, an app, Alexa with routines, and schedules....who knew.
Great help thankd
Thank you!!!
Thank you
Thanks 🤩
How to replace battery on nest thermostats
Mine no longer connects to the internet
U need to connet the c wire thats why to keep 24v
After two years no matter how much you charge the battery manually, without a C wire connection these batteries will die fast just like a cell phone and will take a recharge every other day. There’s no way to replace the battery. Better off dropping the nest and going with a better option.
I received a replacement and now a year later the nest is battery low again. I keep having to recharge however it's December and winter. I keep worrying about my pipes freezing and my bill for the month. I'm going back to Honeywell.
Thanks
I bought a new house and it had two of these things in it, I hated them. This thing is really bad at being what it is suppose to be, a thermostat !
Granted the physical hardware is nice but the look and the so called cool factor have people jumping through hoops and putting up with so much crap for a thermostat.....a thermostat people.
Reboot my router? I cant remember the last time I rebooted my router, and my whole house is smart, now I have to set up a schedule for that for the darn thermostat. I put in a Honeywell and havent touched it, with a nest you want mee to scroll through 20 menus to check the battery. Dont get me started on this thing performs when actually worked.
funny my batt is bad nest said you are out of luck buy a new one the batt should last 5 -10 years but they are failing at 2
Everyone needs to reset their internet every few weeks? I’ve never reset my internet. Never had issues.
Low voltage in
Such a stupid thing! God help you if this happens while you are away in cold weather! I'm ready to go back to my old fashioned dependable thermosthat!
you need to add a c wire.....
he should install the c wire so it can charge the battery
"typically everyone needs to reset their internet every few weeks anyway"
If you have to reset your internet every few weeks, something is broken. You literally should never have to restart your modem or your router other than in extremely rare cases.
That is not what my internet provider, nor the IT people at work tell me.
If you have the equipment that the home isp typically provides than yes, almost definitely you'll have to reboot a couple times a month lol. If you buy your own high quality modem and router than maybe not so much.
Earth is flat
why a Collin Alred commerical, I will not come back to you
🥰🥰🥰🥰
All this explanations, doesn't make any sense with Nest power issue . Simple, you need a "c" wire from furnace, or use one of multiple solutions how to add it.
You have just saved me! Thank you ❤️
Thanks very helpful
