Battery life first impressions

Now I'm coming from a well used note 1, the note 2 may well have been a lot better, but this is very impressive. I listened to Spotify for two hours, set up Gmail and exchange push email, messed around with it a lot during the day and I still have 44%.
I was thinking of getting the wireless charging back but don't think I'll bother if it is easily going to last a day with heavy use!

Impressive. #1 in my opinion is battery life. Wireless charging is just too cool and convenient to not use though. You do it everyday, mind as well save yourself a few seconds a day, it adds up!

Indeed, I am still tempted although I think I'll wait to see how thick the official wireless back cover is.

I've been using my device all day and connected to my Galaxy Gear and at end of the day battery still has 50% charge left. Very impressive.

To judge battery life accurately, you have to include a number of variables on your device's configuration
-How much screen on time(note 2 gets 5-7 hours rooted and rom'ed)
-Auto brightness or what percent brightness?
-How much time on LTE and how much on WiFi? weak or strong data signal?(red yellow or green in battery stats)
-WiFi and/or Bluetooth and/or GPS on or off when connected to LTE?
-How many reboots since last charged?
-How much data transferred through the radio?
-How many minutes of voice calls?
-Samsung power savings mode enabled or disabled?
-SPen finder on or off?
I might be exaggerating but I think that the above counts when you have thousands of people posting various findings with vague information

My comparison is against my other devices. My Note 2 would need a charge at the end of the day so for me the Note 3 has better battery life.

You don't even have signal. This is all based on WiFi. You should do it with data.

Nope. I just got home where I have bad signal. I have been in London all day with full signal and wifi.
Just some general impressions compared to my old note 1.

You guys are getting too particular. First impressions.

Actually they're not. It's like getting a new car with almost the same engine and transmission and just saying it's faster. How about some times to show how much faster.
Poster above said his Note 2 would already need a charge and he still has 50% battery left. Either his Note 2 battery was faulty or he has misjudged his usage on his new device. The 3 will have better battery life than the 2, but not double. Congrats to all the lucky ones that have it already!

Don't forget that it's new more efficient processor and Android 4.3 in note 3 in comparison note 2 and i logically assume that overall must be more energy efficient phone. I also believe that if it wasn't sammy wouldn't had put only some miliamps better battery but a lot bigger maybe making a bit thicker.
Just my 2 cents

Who cares how accurate the first impressions are at this point, many of us pre-ordered one. We like developments and information, quit destroying our dreams.

Good point my Note 2 battery is not new. But the battery in the Note 3 holds more charge. Also Note 3 had BT4 which is very battery efficient.

Sure, old batteries may not be the best comparison, but new batteries aren't at the top of their game either. Lithium batteries generally need a few charge cycles to reach peak capacity. Maybe not scientific, but it's good to hear people are pleased with their initial results.

Battery Life - wlan_rx_wake - Better Battery Stats Images

Hi,
After using Better Battery Stats I found that while at work the open wifi for guests and employee devices is causing my phone to not sleep - specifically the wlan_rx_wake wakelock. I did run shark and analyzed with wireshark and can see that my phone is responding to/waking up for every other device on that network (my office has over 5,000 individuals in it so presumably there's pretty close to that many connecting). So today I "forgot" the open wifi network and only used mobile data. no more wlan_rx_wake.
However I only got about 20 hours of battery...not sure if thats good or not...that included a 30 min lunch break at the gym with runtastic and iheart radio running - on the gym's open wifi.
Below are some screen prints of BBS at the end of the day (I unplugged last night 3/25 at about 9pm...and I have wifi and data set to be turned off via tasker from 11pm till 6:30 am every night so my phone doesn't blink all night when it gets messages - it's right next to me) It's also running the SUPERLIGHTROM v3.
Any thoughts or comments on how to extend the battery life is welcome!

That's solid battery life on the S3 right there. Unless you have an extended battery that's about as good as you will get. I never got that type of battery life on my S3

I wondered if it was. I've considered the zero lemon battery but not sure that I want the increased size.
I've gotten better battery life before by using tasker to turn off/on wifi and mobile data every 30 min or whenever I turn on the screen.
I'm contemplating upgrading to a LG G2 or a Moto X (2014) just for the battery because there's nothing that they do that I need that the S3 doesn't already satisfy.

Let's see that battery life

Post up your screen shots and show us how good or bad your battery life is. Tell us whether you have the snap dragon or exynos version, what carrier you're on, what tweaks you may have done, whether you have the S8 or S8+.
I have the Snap Dragon S8+ with T-Mobile.
I have auto brightness on, with optimized performance mode on. I have Wi-Fi, Bluetooth, GPS enabled, always on display is also on. I have not shut any apps off except lookout security. I have adguard also. If I can answer anymore questions, let me know.
Best battery life I've ever had on a phone.

Will be nice if people post their settings too especially those with crazy good bat life

I'll post mine at end of day. Going all in, running Twitter and also normal multitasking and playing music in the background.

Not real impressed with mine yet, I know it'll get better but I've only gotten 1hr screen on time so far.
Display set to 1080p, 50% brightness, smart mode, and very little use other then streaming music.
But my lg v20 lasted that long doing the same everyday. Not sure why android eats ups battery streaming music, my iPhone 7 plus can stream music for 8 hrs and still have between 85-90% battery. Hopefully android will make it better.
Like the phone so far though. It's a lot smoother than my s7 edge was.

Cool. I'm getting the regular. Should be somewhat close to that I'm thinking. Whats exciting is that your battery life is out of the box. The software must be much more optimized and the processor efficient.

And this is with all kinds of wonkiness going on

Playing music almost constantly since 830, maps, bluetooth, and browsing. 60% brightneess and WQHD+

Here are mine. Still about 24% left. About 30mns call, 2hrs google play music and some facebook,youtube etc

Here's an update on mine after getting home and not steaming music. I'd say if you don't stream music they battery is awesome. I'm happy with battery. Just wish they would optimise music streaming with screen off like apple. But not complaining, I'm happy.

I have an S8. I'm quite impressed. WQHD+, 50% brightness

You guys are happy with your New toy thats why screen sips most of the Juice however whats interesting is testing idling on 4g/3g and see how much Android os is taking

Galaxy S8, 5hrs 36mins, blown away by it considering I was only getting 3.5hrs on the S7, disabled some bloatware through package disabler and on about 30% brightness

4 hours playing super Mario sunshine with a ps4 controller got me about 4 hours 60%
720p 50% brightness.
Figured the iPhone 7 is 720p why not save battery

Question Battery Life on both Galaxy Watch 4 44mm and Galaxy Watch 4 Classic 46mm

Hi all
As of now there's not much videos or topics around the battery life of the Galaxy Watch 4 and Galaxy Watch 4 classic beside knowing that the smaller of size of each model will have a smaller battery life since they sport a smaller battery.
Galaxy Watch 4 44mm and Galaxy Watch 4 classic 46 mm both have the same battery, but since their size is different, I assume that the regular Galaxy Watch 4 44mm has a slicely better battery life.
What are your thoughts ?

The screen is the same so battery life is the same. Around 2 days on light use and 1 day with heavy use.

I agree with davigar. I have a classic 46mm. Not running wifi (only bluetooth) and I'm getting about 2 days with no workouts or gps. This is with notifications on with gmail and texts but that is it. Doing workouts and/or gps about a day and a half. Coming from Galaxy Watch (1) which was 4 - 5 days with mixed use. I was very concerned with battery time going to this watch but the added features, better display, better and faster processor, and not being as bulky has won me over. This really is a superbly designed watch. Very happy so far.

Nice ! I just ordered yesterday! Galaxy watch 4 classic. Well i had the Galaxy Gear S3 and with the usage I had the battery life was like a day and a half also so... I probably won't feel any problem regarding the battery life based on both of your feedbacks. That's good to know !

I confirm. 2 days of light usage.

I also have a 46mm GW4C and i get just under 2 days with moderate usage, bt on , screen brightness at 90% , 20-30min navigation a day, all notifications

I think that the battery life is pretty poor. I have the classic LTE. If I do one hour of cycling as a standalone device using the health app and of course GPS, and then walk for an hour, same settings as I don't want to take a phone with me, I found the battery almost completely drained. So using lte, and gps, and the health app, which is the purpose I bought this, while exercising for a not too long period of time, drains it and is very disappointing to me. I had the Galaxy watch 3 and did not have this issue. Also the Apple watch 5 with no issue.
I also find that while it is wonderful to have a browser on the watch, when used as a standalone to listen to streaming radio the device overheats after only 5 or 6 minutes. It literally goes into airplane mode.
Knowing samsung, they will fix this in updates but I hate paying to be their r&d.
I think this watch looks great and most of the software works flawlessly, but if you are planning to use this for serious exercise as a standalone then you may be disappointed by the battery life.

Brilliant watch, but disappointing that the battery life is not a but better - made even harder because it doesn't charge on most wireless chargers....
Does anybody know the impact on battery life of;
1. Wifi - if it does impact noticeably is it needed if you have Bluetooth on and have the lte version with esim activated?
2. Continuous HR monitoring as opposed to every 10 minutes
When you start to monitor an activity - does the 10 minute HR monitoring automatically change to continuous?

Don't know for sure about the first two, but as to your last question, the answer is yes - in fact, when monitoring an activity, you should be able to scroll over to see the continuous heart rate readout.
I'm actually fine with the battery life of my 46mm Classic. It does seem to have settled down, and I eliminate or limit the use of battery hogging features and apps. I can get two days - which means I'm solid for a full day (24 hours - not Apple's 'full day' of 18), and that's fine by me (even coming from a Gear S3 that got 3+ days).
Don't forget, this watch does a lot more, we are now on Wear OS3 which brings significant advantages (and, of course, some disadvantages), and it gets more than twice the battery life of the supposed world's best smartwatch (I'm looking at you, The Verge).

Battery life is pretty good in my Galaxy watch 4 Classic, I charge it 3 days once and the only problem is that sometimes the watch doesn't connect properly to my phone.

Battery is fair on my Galaxy watch 4, especially since I use LTE and activities apps a lot...

2 days with LTE turned off (my carrier doesnt do eSIMs) but with everything esle one (including GPS) near as makes no difference the same usage as my previous Active 2 here.
What did alarm me (and prolly alarms new users) was the first days shocking battery usage...that first day i was worried id made a bad choice and was ready to go back to my Active 2...give it a day or two and it sorts itself out.
I wouldnt be without it now...being able to snooze or dismiss an alarm set on phone without having to scramble for the phone is wiorth it alone

GW4 46mm Classic. Note that this is with a lot of standby time over the last few days (watch just sitting on my table). Still, I can get a solid two days in normal use, and I am very pleased with the standby drain:

Question Omg the battery is horrible and a few other things

I've owned Gear S2, Gear S3, GW1, GW2, GW 3 and now the 4 Classic (46mm) and this by far has the worst battery out of all of them. Had the watch for about a week now. Honestly I can't say its any better then my GW3. Short of having YouTube so far its just meh....
Another issue is replacing the bands, I feel like the 22mm bands on my GW3 were super easy to change, on the GW4 I'm struggling to clip them in.

Not too bad here BT model

You do realize that these take 20mm bands?

Mines LTE version

Give it a few more charging cycle's....

I got the small version and battery live is terrible as well. With sleep Spo2 tracking and sporadic HR and Stress measurements it doesn´t even last 24h. Then it takes more than an hour to fully charge.
I´ve had the Oneplus Watch until now and apart from the fact that the design on the 1+ watch looks way more refined the battery live using the same features is at least double... Also it charges to full in around 30min.
Guess I will return this one and get the larger Model to see if it any better...

I have found I'm getting better battery time after more full charges. When I first got watch I was getting about a day and half with some workouts and 2 days with light use. On my previous charge I got 2 days and 20 hours. This was with light use. On my current charge I'm at 1 day and 3 hours at 46%. I have had 3 workouts with 1 using GPS. I expect I will get nearly 2 days. I was expecting a lot worse. I'm happy.

And that is the reason it takes me 20 minutes to swap a band? I'm just saying the 22 inch bands on the GW3 were super easy to swap and not so much on this one. Both on my GW4 classic and my wifes GW4.

I think it is more the function of the band. I am partial to Fintie nylon bands, and it took me less than 5 min to swap those for the factory rubber bands.

I bought a 20 mm Barton Elite Silicone Watch Band and swapped them out in under 30 seconds. Super easy. I guess it could be related to the brand.
​

My barton bands, I can swap in WAY UNDER 30 seconds. If you're taking that long to swap bands, you have a crappy band. Battery life isn't amazing, but also isn't horrible. My lifestyle allows me to recharge while I'm taking a shower so all good there.

I just purchased this model yesterday and still figuring out the battery life. Used it at work with wifi connected and bluetooth on (mine is the bluetooth/wifi/gps model, not the LTE one) and using spotify and replying to messages and so far I'm at 81 percent. All I have enabled is the fitness tracker but heart rate/stress levels etc are set to manual.
