I am sick of hearing about how bad the battery life is on the Gear.
My Gear have great battery life, charge it every two days but yesterday.
The Google Smart watch is coming and it has much better battery life that the Gear's 12 hours??? !!!
Who can only get 12 hours on the Gear, and what do you do to burn the battery that quick?
Mine also lasts 2-3 days.. I'm connected to the note 2 if that makes a difference.

Should make no difference at all.
thats because most reviewers dont know what they are talking about
My battery life is great. 3 to 4 days moderate use. And worse comes to worse wack it on the charger while i get ready for work and I have a days worth of battery.
I have a feeling they had pre-release versions which may have had worse battery life. Shame!
Yes, with more recent gear manager updates, I get around 3 days+
Mine lasts 3-4 days.
But I am only using it during the work day.
At the end of the day I have 85% left everyday. I think its biased reviews. I'm sure if the apple watch had a 6 hour battery they would says its genious and revolutionary.

As a longtime 'professional' reviewer for over a decade (for the high fidelity audio industry), the non-rooted watch gives about 2 to 3 days battery life. Also, I don't recall seeing any reviews where they sideloaded apps, which makes the watch even more useful :good:
Frankly, don't trust all reviewers. :cyclops:
hahaha .... :laugh: ... they (those reviewers said about bad battery life) have already decided just on the number of xxx mAh. (once they see it.). :laugh: :laugh: :laugh:
I NEVER TRUST ... I TRUST MYSELF ON WHAT I HAVE DECIDED and TRIED ON MY OWN.
My battery life is 3 or 4 days. .. depending of use .
I think it depends of 'home screen ' . With watch styler, if my watch face is 'white' battery life can be 2 or 3 days. But with a standard watch face (black) battery life is 3 or 4 days...
If bluetooth is always turn on, the other battery's drain can only be screen... and it depends of the number of notifications you receive every days ! (And number you look at your watch daily )
Yes I agree with you on that I get 2 to 3 days of battery life heavy usage brightness at 4 and timeout at 15
Yes my Gear had pretty decent battery life, 2-3 days. Works out great just plug it in when I go to bed.

I have been using my gear on an S4 with android 4.2.2. Battery was usually about 50% at bedtime. I updated to the android 4.3 yesterday which gave me full capabilities of the Gear. Today after 8 hours of pretty heavy use (lots of email) I am at 90%. 4.3 does a much better job of handling BT connections, not just on the Gear but my other BT devices.
This is my 4th smartwatch (Sony MN800, Sony MN2SW, Pebble). The Sony MN2 was pretty decent, touchscreen/color but its battery life was terrible, had trouble making it through the whole day. Pebble had great battery life, constant on screen, but having to use buttons and no color was tough for me after having a touch color screen. Gear is definately heading in the right direction for me. Now that the battery life is can last 2+ days I am even more pleased with my decision to dive in. I turn the screen brightness to +2 which is extremely bright for indoor use.:good:
Yep, agreed.
My battery life is more than I can hope for with this thing.
I'm on day 2 and still have 61 percent battery life left.
I have screen brightness on 1 (which seems perfectly viewable for me) and time out for 7 seconds.
I can go 4 days easy with my current settings.
While I agree the battery life is a bit better than the reviews suggested, I'm surprised so many of you are getting 3-4 days worth. I use mine very lightly... it's stock, I don't have hardly any apps loaded on it, I'm currently just using it to occasionally see the time, and get txt/call/email notifications. I have the most battery efficient watch face (the black one with orange hands and only four markers), brightness on 4, timeout on 10s, using the latest gear manager on a stock Note 3. After 48hrs, I'm below 30% battery. The only excess usage I get is from the auto-wake... I do notice it coming on sometimes while I'm driving, or at the gym. Other than that, I really don't see how I could use it any less to get more life out of it (other than not using it at all). Once the software gets updated to make it a little more useful, I would expect battery life to get worse.
I'm not complaining, 2 days is acceptable to me, I just would have expected my usage patterns to put me at the long end of battery life relative to other users, rather than the short end.

I agree the reviewers had very bad results or bias, But at the same time I wish I knew how you guys were getting your results. Today was a light day, got maybe 20-30 texts and 5-10 emails. Didn't make any calls or respond to any texts with S-voice. I did just realize I had reset it recently so the brightness was at 4 with a 10 second time out. I normally run brightness at 2 and timeout at 7 to try to save the battery. I also use strong vibration and have the digital clock/weather watch face with a black background. I am at 82% after 12 hours, which again I don't think is bad. That would net me 2-3 days, but again that was what I consider very light usage. With heavy usage I doubt it would make it through the day.
I'm not complaining because I am ok with charging it every night, so long as it makes it through the day I am ok with it. I would just be happier if I knew I could get 2+ days with medium usage at least, including bright screen and all that jazz.
Also, side tracking I know, but what apps have you guys side loaded that you have found useful?
I have brightness at max and use it VERY heavily. I work as a mobile computer tech and all my calls are taken on it, I use svoice to make calls, I use svoice to reply to SMS and I'm always playing with it. The lowest battery at the end of a day (by which I mean 7:00am until midnight) was 38%.
I really cant fathom how it would be possible to deplete the battery in just 12 hours.
my use today :
I read 15 sms, 10 mail , take 3 pics and call with my father 15 min with gear speak phone (and the other 15 min with the phone.)
blue tooth connected permanently.
Number of auto wake : ?? A lot !!
Time Out : 15s
last complete charge : this night ( disconnect at 8 am.)
Now I read 1:28 am.
Battery level : 61%
it's all rights !!!
until your phone dies.
After being rooted and debloated and functioning flawlessly, my Note 8 died last night after literally 6 months. While the battery was low, I'm not sure it was so low it would crash and shut down, not returning to life again after several known attempts to revive it.
So, after looking at the Big Internet Thing, it appears this is rather a notable issue associated with the Note 8, with phones crapping out around 6-7 months. Pardon the pun.
While I am receiving another from Verizon tomorrow, I'd advise you keep track of your warranty and pay attention to how your device continues to perform, particularly around charging issues and battery health.

Mine is 8 months old, battery health was 93 when i bought it, today its jumping around 91-89 currently 91.35 . Never let your phone discharge below 20 as it is seen happening...
I have my phone since 22th Nov 2017, so, it is almost 1 year old, and the battery behaves exactly as day one, obviously it must have aged, but, I have never let it drop below 15%, only on rare ocasions I have charged it to 100%, and, what I consider really very important, I have not used fast charge
I installed accubattery just to check the "battery health" , it reports 92%
Update Nov 19th 2018
Now batt health is 96%
I think it's a serious engineering flaw if it malfunctions when charging under 20%.
I also read that one trick that might work is to use wireless charging AND USB charging at the same time.
Double Crappy Engineering
Been using my N950N since I got mid March and it has been working like a dream. Touch keyboard that I won't experience this issue.
No issue had mine a year
Although to a certain extent, we even came to doubt that Samsung would update the Galaxy S9 and Note 9 devices with the OneUI 2.1, it is finally here, and it cames with Deep Sleep Apps feature, which will allow to actually suspend all services and processes associated with an app.
This has resulted in a relatively big battery life improvement when the device is on standby with S10 and S20 devices in controlled tests1.
Galaxy S9, S9+ and Note 9 are devices released more than 2 years ago, and surely the battery stamina is not the same as they were in their first months of use. Samsung stats that the batteries used on these devices should keep a decent stamina for 2 years with the average user.
Some people have used their phones with battery care measures1, in order to extend battery life.
So, with the recent release of OneUI 2.1 for Samsung Galaxy Note 9, the battery life with the device in standby is expected to be longer (but not the screen on time), although the magnitude is yet to be determined in the coming days.
This thread is aimed to share our opinions on the subject, as the update becomes available and we can evaluate the battery life.

IOS uses a choise in his battery settings to charge the battery up to 80 % of it's capacity and then charging will stop to improve the battery's durability.
It's known that standing in battery's 20/80% capacity increases its life and durability and doing this you can charge how many times you want because one parzial charge will not be counted as an whole cycle of charge so the battery might last more than 3 years going on like this.
This choice is not implemented in Android even with one UI 2.1 and it's a shame even if the new feature will improve battery's autonomy due to the lower consumption of the apps and even if it's impossible to perfectly be able to stay in it's 20/80 percentage range, there's an app that I found that will avert you when reaching 80 % of its charging capacity so you can disconnect the cable to preserve the battery....

You're right and I keep charging between 30 and 80 but this shouldn't be how the phone charges by default as you said. Many people charge from 15 to 100 and want that extra 40-50% they'll get by doing so. I found that without fast charging it takes 1 hour from 30% to 80% so it's no big deal to look at the clock when you leave the phone on the charger.

Even your right, there are even people that continually from 0%(completely dead) goes to 100% after charging the battery for the whole night... that's why what I said for charging should be a choise (like in IOS) and not a default setting.... strange thing that Android or Samsung didn't consider implementing this choise. Fast charging even worns the battery first... it stresses the battery and it will last less but at least they gave us a choise in using it or not.
Absolutely true! Samsung should have implemented a feature to limit charge at 80%, or implement a Bixby Routine to enable this behavior (for example, when charger is plugged at night)
50% increase in my case. And i used OTA Package to update manually.
From: 4h SoT in 24h
To: 8h SoT in 24/30h
Idle times are impressive.
EDIT: just FYI, i rarely charge up to 100%. So my average case is from 85/90% to 5%. Very rarely do i go for a 100 to 0.
One UI 2.1 improvements are all courtesy of the Deep Sleep feature.
I've added everything i barely use or dont need to create wake-ups on the Deep Sleep list. On the normal sleep list, i have low priority things like Play store, etc. And i make sure i white list everything i need untouched (Messenger, WhatsApp, etc) and also do the same thing on the Memory management. Solid results.
Edit: 100% to 1%. 10h SoT with a 30h cycle. It's like getting better and better.
My tab a 2019 has the 80 percent feature and I do not understand why they wont offer the simple setting actually I do because phones they want you to replace the phone instead of the battery in 2 years. I run my note 9 from however low to 100 every night but only because I dont have the option these newer android 9 then 10 now 2.1 adding more and more apps into the firmware but wont add a simple little feature as this. Also I would like to be able to choose if I want to do ota with my data! But I cant.
For me One UI 2.0 was already worst with about 3 to 3.5 hrs of screen on time. Now with 2.1 i barely get close to 2 hrs of SoT. My note 9 is running stock since i bought it at launch and have never done any factory reset. Only thing i do is wipe the cache after a upgrade.

Bro you need to factory reset and start fresh and if that doesn't help something is wrong with your battery I get 9 SOT all the time with 10 2.0 with android 9 it was about 6 SOT, I haven't received 2.1 yet. I have us unlocked version.

You have a snapdragon variant which is anyway much better than exynos variant (my phone) for battery backup.
Sent from my SM-N960F using Tapatalk
Stop saying Exynos is not good for battery life. I can easily get 8h SOT of regular usage on my SM-N960F running OneUI 2.1. Obviously I don't play games like Asphalt 9, etc but I never use power saving modes and never limit myself in order to save battery life. I play 8 Ball Pool when I want to, I watch YouTube for as long as I want to, I browse Instagram and use Samsung Internet Beta when I feel like it. Not once have I ended up in a dire need to recharge when I was outside or when I needed to use the phone. Also the phone charges 50% for 1h (I charge between 30 and 80%) so I just leave it charge while having dinner, watching TV or something like that - when I normally wouldn't use the phone anyway.
On my N9 seems battery life abit improve from previous 2.0. Sammy did great job this time.
Here is my screenshot to prove it.
It takes time to see improvement in your device's battery life after installing OneUI2.1. As the software AI needs to learn all your habits again before any improvement in battery life will occur. This process should take a few weeks
So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review.
Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.
BUT, yesterday all the youtubers started to publish they're videos comparing batteries with older S devices and Iphones and their S21s were doing amazing, giving them screen on times of up to 13 hours!
I contacted support but they said this would be normal as my phone was still learning user patterns... but I'm not sure if that would affect it as bad as it is at the moment.
Also, I installed accubattery which is not 100% reliable but compared it to my note 10+ and it seems that battery health is even lower that my Note (95%)! Which I've had for a year and a half!!!
What do you guys think? Should I send the phone back? I'm really concerned that I just spent all this money on a new phone for it to be so bad with battery.
Try disabling all power management.
In Developer options>standby apps all buckets should show as active otherwise power management is running.
Google Play Services, Backup Transport and Framework are known hogs.
Disable all the bloatware, turn off auto sync for gmail, turn off all feedback.
You'll need to sort it out and optimize it. Took me months to get my 10+ sorted out. Fortunately it's running on Pie so I had more diagnostic options.
Returning is a thought as 5G may have been poorly implemented and another source of power drain. I think everything after the 10+ 4G both hardware and OS are train wrecks... I see very little incentive to "upgrade".
Maybe post screenshots that aren't below 5 kilobytes. Lol. I'm guessing you have an Exynos variant?

It's too early to judge the battery life, also accu battery app is not good at all, it's not accurate as your own phone's batterymeter.
Also, you need a week or so to make sure the phone get optimised according to your usage.
Does your phone have Exynos 2100 or Snapdragon 888?

Mine has the Exynos 2100. I was just going off from videos like Mrwhosetheboss. He got 8 hours of screen on time. And he probably tested it when he got the phone no? And I'm litteraly getting half of that... and not even pushing my phone to the limit like he did on his video. I mainly use social media apps and YouTube.
I suggest doing a factory reset before you think about sending the phone back. Also, initially, be careful about what aps you install - try going with a minimal number of aps so you can get an idea of how the battery does when there are no aps that might pull from the battery - after a few days, add all of the aps you have been using (while avoiding any that might be a battery drain) and try for a few more days to see if you are seeing improved battery life. Good luck - hope it all works out for you.

Reloads -never- find the root cause and many times even if the problem is "fixed" it eventually returns.
Exceptions; old loads, software induced bootloops, viruses, and major firmware updates.
Expect issues with the 5G devices from poor hardware implementation. No fix for this.
I am on the first charge, but the battery life is so far pathetic. Omg! And everyone on youtube praise it... Down to 85% in 2 and a half hours and 50 minutes of SOT. Shame...

How much with screen off is it sucking down?
If more than 1% @ hr with AOD on it's probably Google and cloud crap running in the background.
You can optimize it to improve performance.
It's easier to do this with Pie though; Q and 11 take away critical tools and use scoped storage which wastes cpu cycles.
Get Karma Firewall and a package disabler like this one;

Regardless of the model or OS version most carrier phones will need to be optimized for good battery life and optimum performance.
My 10+ was a hot running bandwidth hungry hog until I toned it down. Today it's hard to believe it's that same machine.
You are right, I agree with all you said. It is kinda sad though, as for instance, my ex Asus Zenfone 7 Pro had an absolutely mindblowing battery life, without any tweaks. I just used it. With all the hype around the S21 Ultra, I believed it again. The only Samsung I used with good battery life was S20 FE 5G.
Will give it a go with what you say though, thanks.

Well, i believe what you are saying about battery life, but what i have seen so far is promising, i mean when S21 Ultra with Exynos 2100 beats iphone 11 Pro Max and 12 Pro Max, i guess that's a good sign!! But for sure, we use our phones in different way than each others because maybe you use it with 4G/5G enabled almost all the time while these tests are just using Wifi and maybe without any SIM card which means the battery consumption will be minimum at this part.
I have S20 Ultra with Snapdragon 865, i get like an average of 6 hours SoT and if S21 Ultra Exynos gives me the same SoT, i'll be happy!!
SOT is not everything...we travel, we move, you cant accept a phone that gives you 12 hours of standby in total. This is bs and useless, you cant rely on such a phone.

My AT&T 10+ was not real bad (or good) the first few days. After enabling power management it went to hell.
Eventually I disabled all power management and one by one tracked down the hogs.
Because of dependencies simply disabling and/or turning off say Google Transport and Google Framework isn't enough, firewall blocking Google Play Services* then clearing data on all 3 periodically finally stopped this hog dead in its tracks. These will run in the background when the screen is off stealing power for nothing. Sometimes the Google apks are misreported as other Google apks presumably because of the interlinking dependencies.
Try using Galaxy Labs Battery Tracker.
Developer options>running apks/cache can also yield clues. With an unrooted phone there's some serious game playing to track this garbage down.
Anything app that's cloud or carrier is bad... lol.
Disable all feedback and syncing except for texting; manually sync gmail.
*needs to be unblocked occasionally for gmail to download and for Playstore (another apk you should disable/firewall block when not using).
Try disabling 5G if you are not using it, for some ppl SmartThings drain a lot of battery but you should see that app in log. Can't wait to get mine, also E2100 and coming from Note 8. Was rly looking to have a 2 day phone.

That's a thought that's worth a try.
From what I've read even disabling 5G doesn't completely stop it's parasitic battery drain.
Maybe the latest generation chipsets are better but early 5G was poorly implemented giving a marginal speed increase on most phones of 20% when available.
Is this on the snapdragon or exynos variant?

So, 15% drain in 2.5 hours with nearly an hour of SOT. 15% is about 1/7 as a fraction. Now, 7 * 50 / 60 = 5.83 hours of SOT and 2.5 * 7 = 17.5 hours total. My Note 10+ (S20 Ultra on order!) doesn't do any better and NEVER did. If I use my phone for 6 hours a day (of SOT) it's pretty much done for.
I think people are being way too picky these days - just complaining to complain. If you really want I'm sure you can tune your phone so it gets 3 days on the battery. It'll suck and not do much of anything but, sure, you can do it. I've got a smartwatch and the same thing applies. I can tune it so it works for two weeks on the battery or I can actually use the thing and get 2-3 days. I choose 2-3 days and have stuff I want to use. I'd rather my phone be reactive and tell me when I've got emails, etc than to get super long battery life and basically have an inert brick in my pocket. I have a cellphone so I can use it for stuff. If that makes the battery not last long, oh well. If it can get 5-7 hours of screen time while also lasting through the day, great.
My 10+ draws roughly 1%@hr* with AOD on.
SOT draw varies between 9-12%@hr
Roughly 10%@hr watching vids on Samsung internet with surfing on Brave being the highest usage.
I consider it fairly optimized at this point.
*4300 mAh battery with little degradation.
No 5G running on Pie so not scoped storage either.
Figures are from a charge range of between roughly 40-65% as I rarely charged beyond 70% or discharge deeper than 30%.
Actual usage be more if I had started at 100% because of the power density difference through the power range ie 1% at 20 is far less watts than 1% at 100%.
A/V=watts. Less voltage means less overall mAh per % plus the additional losses due to voltage stepup power conversionas you dip towards 30% The closer to 100%, the higher the voltage with more available mAhs per battery% as well as less stepup voltage power converter losses.
A phone's wattage and V+'are constant so as the battery voltage decreases it draws more current ie mAhs.

So, 15% drain in 2.5 hours with nearly an hour of SOT. 15% is about 1/7 as a fraction. Now, 7 * 50 / 60 = 5.83 hours of SOT and 2.5 * 7 = 17.5 hours total. My Note 10+ (S20 Ultra on order!) doesn't do any better and NEVER did. If I use my phone for 6 hours a day (of SOT) it's pretty much done for.
I think people are being way too picky these days - just complaining to complain. If you really want I'm sure you can tune your phone so it gets 3 days on the battery. It'll suck and not do much of anything but, sure, you can do it. I've got a smartwatch and the same thing applies.

You are also right, but , when you used something that does both keeping you up to date, and having a brilliant battery life, then it becomes disappointing when you change it for one that doesnt.
Hi There,
I've had my Note 9 since December 2018 and it has treated me very well. Still does all that I need to do, as fast as I need to do it.
One small problem - the battery life is fully shot. Having to charge multiple times a day. I tried a while back to see if Samsung would do this for me, but they suggested that I wouldn't get much of an improvement in battery life due to software updates etc. I assumed this was sales bs but have found mates to have battery replacements to make a difference.
Therefore - is it worth doing a battery replacement on this device? I get about 5 hours I think at the moment. I would be interested in your experience. Just to add, I've smashed the bank panel pretty badly (everything still works) so probably would want to replace this as well (as they are a fiver on ebay - again purely cosmetic).
Thoughts?
I did it 1 month ago. It's now waiting for the 3rd battery, been for 1 week in the shop. All the new ones ware manufactured in winter 2018 and were weaker than the 2900 mAh left in mine after 3 years, so no.
Fair aha thank you !
By the way, just got the new replacement. It's much better at 3600 mAh after one charge, and I could get around 6 hours of Revanced yesterday with 25% still left.
Interesting - and you have had success with it?
I'm just sitting here googling this very subject. My battery is still pretty good in normal usage, but struggled to get through a full day in a recent hospital stay (when, admittedly, I was using the phone much more than normal). Torn between a battery replacement, S23 Ultra in a few months, or stick it out for another year and hold out for the S24 Ultra. Note 9 is still perfect in every sense (I have the 512Gb version), it's just the battery life is starting to weaken. If, as you say, the genuine replacements are manufactured in 2018, I might just go for the third option and hold out for the S24.
I use AccuBattery for a long time. It estimates my 3 years old Note 9 battery is 74%. I go to service center and change battery. Now it's 100% after a few full charge. I feel significant improvement in battery usage, maybe 1-1.5 hours more on-screen time with same softwares, same usage.
