I bought my transformer and updated it to 3.1 on day one. So I don't know how good battery performance is in 3.0. But after updating to 3.1, one day stand by drops the battery level to 50% with wifi on. Is it normal?
That would seem normal to me if you're leaving your wifi on all the time. Really it all depends on how many background services you keep running while the device is in standby. In my case when I first got my TF, the wifi was never set to turn off while in standby, so all of my accounts and application synchronization continued while the screen was off. My battery typically lasts about a day or two if I allow those services to run when the device is not in use.
If instead you turn off the wifi, sync, and even live wallpaper, you should be able to get a few extra days of standby time.
Normal for me is 3-4% drains overnight with wifi on. Sometimes it will drain ~20%, and goes back to normal after I reboot it. Must be some rogue app or something causing problems.
It lasts a lot longer if you turn wifi off.
Better yet, check out JuiceDefender. It has a free version and paid versions that give you more control/settings. Try the free one. If you need better control, then buy it. I don't buy lots of apps as usually the free ones do it for me, but it really works well.
The only other app I bought was TitaniunBackup (for my phone, but as it turns it, once you root the TF, it works there too.)
Other threads already started here seem to indicate that while docked the TF will drain at around 5%/hour while in standby (wi-fi or no) and 2%/hour while completely turned off.
This is not the case when the TF is not docked so this is not necessarily a question of having wifi on or rogue apps.
I would not consider this an acceptable drainage level. Hope Asus is looking at this problem and a firmware update will fix this...
Otherwise, very satisfied with the combo.

yeah, I was expecting much longer stand by time even with wifi on from a tablet. Asus should fix this to be at least close to what ipad does.

Others may correct me but I think the standby time with wifi for the tablet is ok. The battery life is a problem only when the TF is docked.
Nothing wrong at all with the battery life, not sure where Asus are getting their 8 hour battery life from, I have far exceeded 8 hours and have currently been going over 5 days (still with 20% left)
i think the battery life is based on playing 720p video at a certain screen brightness(60 nips or nits i think but i have no clue what that means) of course you can get more life depending on what you're using
and i guess everyone has different opinions on acceptable drain but i wouldn't expect my laptop to last more than 2 days if its internet connection is on and sync'ing so why expect a tablet? laptops(that i've used) shut off connections and do nothing when left alone to save battery
people who need their tablet to last for days while not in use(or very minimal use) should just turn off wifi(or turn off the tablet) when you're not going to use it for hours... or leave it charging
Concerning battery drain of the keyboard dock when the tablet is sleeping:
There is a setting SCREEN>MobileDock Battery Saving Mode.
"Disables wake-up function on keyboard when the device is asleep to save more power"
I have to assume this setting should be checked. If not, that may be why your battery doesn't last long when asleep.
Asus states 9.5h (9h30m) battery life on tablet alone, see bottom of this page, *1:
http://usa.asus.com/Eee/Eee_Pad/Eee_Pad_Transformer_TF101/
they tested 720p video @ 60 nits (lowest screen brightness), I think with wifi on.
prior to 3.1 update I've been getting 9h15m to 9h25m per charge.
I use the TF for 2-3 hours at a time and shut it off (not put to sleep) when not using.
since 3.1 the best I got was 8h15m on a charge (same type of use as before).
I went through TF settings, i monitor the apps, got rid of all my Widgets and still am getting over an hour less per charge than before 3.1 update....
there has got to be some kind of a bug in the new release.
granted, there are some welcome improvements in 3.1, but this battery life issue bugs me
I hope Asus fixes it in the next update.

I really hate to be "that guy", but who cares?
As long as it lasts through a day of normal use, you charge it at night, and that's that. I never understood the obsession with "My device gets 5 days without a charge!" Good for you. Those of us who have electrical outlets only need 1 day. Unless you're doing something special that requires you to be away from an electrical outlet for several days at a time, it really shouldn't matter. If that is the case, it's probably your responsibility to look into ways of saving power.
Cutting WiFi while inactive is one solution. Keeping it charged while idle is another.
Stand by doesn't mean 0 battery is used, it means less battery is used. I'd say 50% is pretty decent after 24 hours of inactivity.
Hi everyone
My question is for techy people in this forum.
According to you why standby time of TF is so bad when compare to ipad2.
Is this software or hardware related problem?
Is it fixable?
Thank.

Software problem, IIRC mainly related to the keyboard dock (dock will drain battery when it should be asleep). I still get several days of standby time, which is far more than acceptable. I don't need 2 week standby .
This post needs to go in the proper forum, however.

Sorry, I though this is related to development.
So you are saying that honeycomb is bad by design to battery? Because all honeycomb tablet have the same problem.
There is some thing about standby mode that consume for power than ipad, but why?
It is nice that the tablet does not run out of battery when you really need it.
After leaving my Transformer untouched for about 4 days last week, the battery was sitting in the 80-ish percent area. Seems like pretty damn good standby time to me.
Standby time depends on whether you have the pad docked to the keyboard or not.
If you keep the two separated the standby time is pretty good although I haven't timed it.
If you keep the tablet attached to the dock then standby time for the dock is greatly reduced as it seems to keep charging the tablet until it drains to zero even if you started with a fully charged tablet. It is a very annoying problem that no-one seems to have found a cure for yet. If you let the dock discharge fully some people have found it impossible to charge again.
I am comparing TF and ipad2 without the dock for the obvious reason.
And how long is the iPad 2 standby time?
After using a HTC Desire with poor battery life for the past year I find the standby time for the Transformer to be fantastic. I'm able to use it a bit each day for at least about 5 days. Nothing heavy, but the fact that I can pick it up after a few days of no use and it's still got a decent charge is impressive to me these days.
never used an ipad/2 for extended period of time but stnadby time on the asus is pretty good. what i find helps greatly is if you plan on leaving it in standby for a awhile, then its best to turn off WiFi as it'll help save battery life even more.
i had it fully charged this morning and unplugged it to take to work. Unplugged it around 730am, powered it on and turn off wifi and let the screen timed out. Finally turn screen on at like 130p and the battery still shows 99%
My stand by time was horrible on stock 3.1 I don't why. Once I rooted and installed Prime and OC kernel at 1.2ghz I get much better standby time. Almost comparable to my Ipad 1. Battery life seems to be better too as compared to stock 3.1

let the wifi shut off when the tablet goes to sleep, it's something iOS does by default and turning off radios will make the battery last a lot longer.
also, if you are going to leave wifi connected, the less widgets and applications you allow to pull data (or adjust the intervals they are set to sync), the longer your battery will last. iOS also is a very passive OS so when you put an ipad to sleep, everything is basically shut down, android allows apps to keep running if you have set them to sync data (ie, twitter, facebook, etc) which will also consume more battery.
the dock issue is an issue. but undocked, mine will last a week or so with light/moderate use, then again i generally charge it at night anyways.
and yes, this should be in general section, it has nothing to do with development for the device, you are asking a general question about the device/platform.
I just took my transformer on a 5 day trip, fully charged to start with, and i didn't bring the charger. I probably only used the tablet 3 times for 15 minutes, and the rest was standby. When i got home and plugged it in, it was down to 2% battery, just about to die. That is just unexceptionable. And iPad 2 under slimier circumstances would have consumed maybe around 20% of it's battery life?
I read somewhere that the new samsung galaxy tab 10.1 is rumored to have up to 75 days of stand by. I don't believe that at all, but if they are claiming that, i would assume that i would last much longer than 5 days. (plus i played with one the other day in best buy and it just feels awesome in the hands)
conclusion: hopefully future updates will help out with the transformer's battery life and stand by time.
Thread re-opened and moved to General.

Which is your WIFI policy?
I have it on WIFI off when screen off, and stand-by time is pretty good. I guess that if you need WIFI always on it will adversely affect your battery usage.
Regards.
Its not a Honeycomb issue its a Asus issue. I have a Samsung 10.1 and the stand by time is much better then the Asus. The stand by time for the 10.1 is about 7 hrs and it eats up only 3%. Also, the wifi policy on the 10.1 is set to stay on when it goes into stand by mode. My TF wifi policy is set to turn off when the screen is off and it still eats more battery life then the 10.1. I pretty much have the same apps on both tablet.
Yeah, I have mine set to turn off the wifi when the screen is off (pretty sure this was the default setting), and my standby time is much better than I was expecting (as per my post on the first page). Given the drain I've experienced, I'd expect it to last 2 weeks or so on standby, which seems pretty good to me.
It could be that your wifi disconnect policy is not set to go into standby when the screen goes off. Don't worry, it waits 15 minutes before actually turning off the antenna. But there is a bug where it defaults to "Never" after being charged (including the dock), or after a reboot:
http://code.google.com/p/android/issues/detail?id=16720
I get a few days out of mine, but I don't give it much chance to be standby, I use it regularly in the evenings.
Hi,
I am sorry, I think I didn't well explain it.
It is the fact that TF has less standby time than ipad2.
But, my question is more about Technic.
Ipad2 does email sync with wifi always ON beat TF wifi off.
But why? There is some app working in background? Why it need to be in standby mode?
I still hear email notifications even with Wifi policy set to turn off when screen is off. Definitely a software problem. In regards to the dock issue, ASUS needs to make some changes to Honeycomb so when it knows the dock is plugged in, the power saving features still kicks in when on standby despite the tablet being charged. It probably assumes the dock is actually a wall charger and doesn't kick in any power saving features. (default behaviour set by Google)
I think the main question in this thread needs to be why are people leaving their Transformers in standby for soo long!!
USE YOUR TABLET EVERY SECOND GOD GIVES YOU AND YOU WONT CARE ABOUT HOW LONG IT WILL LAST WHEN ITS ASLEEP
Mark.
I read so many threads and comments complaining about "battery life"
Turning this off and that off, not using this app or that app. Dreaded enemy "wake locks". Turning brightness down and generally Not using all these great devices have to offer to squeeze out more battery life. Even to the extent of over 24 hours.
We have a phenomenal and powerful device that does a whole lot with a huge screen and a ton of great BG apps updating all kinds of information we enjoy these devices for.
MOST of all we all have the (getting rare) opportunity to swap out an inexpensive battery in less than 30 seconds be up and running for another 5-10 hours depending on our enjoyment and use.
Do people not have electricity? They cannot charge every night? They can afford a $600 phone (or $300 subsidized) and $600 plus a year for service but cannot buy a $20 battery in order to actually USE the device as designed and go through all kinds of contortions, apps, settings, and worse, anguish at running out of juice after (gasp) 8 hours?
People getting hung up on "benchmarking" and posting screen shots of phones on battery for 3 days...(of course rarely used) to squeeze and extra 30 minutes.
TURN IT OFF!! bet the battery lasts well over a month. You win!
I guess I just don't understand the "issue" with a device where batteries can be swapped out so easily.
I get maybe 10 hours normally with everything on and at minimum updating. I have infinite screen on and turn it off when I am done using it. (hate those timeouts while reading something). FB and news updates at minimum. Maps always running latitude. If its there its on BT, Screen rotation, GPS, I just don't worry about battery life as I would rather carry an extra battery in my desk at home auto or work and in my wallet than not USE the device as designed.
Personally I would never buy another phone without the ability to swap out a battery lest I would gain have to "ration" my use of such a great device which would be akin to a witnessing a gay man win a date with a single and seductive Angela Jolie . Why bother?
Am I alone here? Anyone else consider battery life as much a non issue as I do on these Samsung phones?
I'm with you on this one. Why do all of that stupid things if you can solve it with $20 battery.

A lot of the battery life threads are related to abnormally high battery drain.
As an example, on GB I would about 1% battery per hour if the phone was idle.
When I upgraded to LPY, I was losing 2-3% per hour, and sometimes higher, because the phone was not going into deep sleep.
This might not seem much of a difference for just 1 hour, but over the course of a day, it is a huge difference.
Now I'm on LPF, my battery drain is about the same, or lower than GB when idle.

I guess "abnormally high" is debatable. For me it would be a 80% battery crapping out before then end of a 2 hour movie.
A day is only 24 hours long and I assume people will sleep for 6-8 hours so Even a 5% drain per hour would mean more than 16 hours of standby with 20% remaining!! How can that be an issue? I doubt my phone "deep sleeps" I have BG apps running all the time with notifications. One extra battery solves all issues. No need for special apps, tweaking this and that, flashing this and that simply for battery life.
If people sleep 6-8 hours during a 24 hour period they can easily and consistently charge their batteries. A 3% drain per hour would not be an issue. If we watch movies and play games we already know the battery will drain within a few hours. Pop in another battery and brand new again.
You are assuming that people are always near a power source.
I am normally near a power source. I am either at work and charge via USB or in my car or at home.
The issue is the past 3 days I was out and about (malls, hotels, restaurants and so on) and was not near a power source for more than 10 minutes. My battery died in about 4 hours of usage. Mostly checking email, instagram and facebook.
I keep my brightness at full strength by the way (unless if the lights are off in bed).
Yes, so battery is an issue.
Not everyone is constantly near a power source.
So you think if I put my fully charged Note into Airplane mode when I go to sleep and wake up in the morning just to find out to my surprise that I lost 32 % of battery life in six hours is normal? In airplane mode? On official update via Kies, never rooted, never anything custom? That is normal to you? Wow, you are either stupid or work for Samsung. If you work for Samsung can you help me to get my GB battery life back? I have already spend good money for the phone, I am not willing to spend a dime extra for another battery on 6 months old phone.
If your phone is working as intended, battery life issues are not really an issue.
It basically means your phone sleeps when its supposed to.
However, some devices never go into deep sleep due to some issue with kernel or a rogue app. Thats where the battery problem comes in.

Thats not normal.
I turn off data and wifi on my Note when I go to sleep (6 hours also) and I loose about 5 to 10 %.
This is with telephone signal only. No data or wifi.
to the post #7. So how come it didn't happened in stock GB previously? In GB I lost about 1 % overnight when in airplane mode. Reliability of batteries on this phone is a big deal, unfortunatelly.
Battery is always an issue. Nobody likes running to the charger every 3 hours. They want to charge and preferably when we are not using it, when we sleep.
So yes, it does not comply with expectatoin with continuous use. So yes its an issue. At least for me
Next to this having the enduser juggle with what wakelocks are or other battery eaters are dont help much. That counts for all smart phones.

There is also the issue about well behaved v badly behaved apps. I've installed apps and my battery life has plummeted, normally due to the app writing tons to the system log as it doesn't run well on my device.
In that situation it's nice to know the phone generally isn't sucking masses of juice itself so you aren't caught out and about with no battery left.
As the OP says, I guess I could carry a spare battery, but I could also carry a spare phone (my old Nokia 6310 used to last weeks on a charge) - and I don't want to do either. I want the battery on my phone to survive general use and still be able to be used for calls if needed. For me, it's not about €20\$20 for a battery, it's about the hassle of having to carry another thing around with me all the time and make sure I'd remembered to charge the damned thing when I actually needed it.
Personally, I use my phone like a tablet and as a phone and generally get 1-2 days out of it no problem. That said there are definitely some battery drain issues with the official German ICS build and it's worth protecting yourself against unnecessary drain if possible.

I happen to believe it's asking far to much of a device once used only as a phone and now as a notebook computer, music player, movie player,gaming platform, big screen, GPS, on and on to be able to operate without expecting batteries to wither within hours. I bought extra batteries so I can use all the functions without worry. There are performance issues people strive to enhance. I get that. But battery life is counter productive to enhancing performance.
I cannot understand all the teeth gnashing about battery life with all the options available Especially those of us who are power users. . not the least being charging while asleep. So many post battery loss while sleeping...... That's what chargers are for.

Sometimes. I go to music festivals where we camp for up to 5 days at a time. I may have access to a powerpoint for 30 mins a day, but not always. I carry spare batteries, but that doesn't mean I want my phone sucking my battery like crazy.
When travelling around, I use my phone more often than normal (gmaps etc)... If I'm away from the hotel for 12 hours +, again, having decent battery life is not an unreasonable thing to want.
My Desire HD (yes I know, smaller screen, slower cpu), could pull over 30 hours out of a battery with conservative use (without turning the radios off).
I still wouldn't give up my Note, but having to recharge each time I get home is pretty annoying.
Ha, ha!
I find it funny that a post complaining about people complaining about battery life ends up with people's comments complaining about battery life!
Seriously, though, when those rogue apps steal my precious battery, I get annoyed. I paid for the damned thing, and I want to use it when I want to use it, not find it is half-drained.
I use it pretty normally, and charge it every day (new batteries are cheap). I carry a spare in my wallet too.
I sometimes spend four hours a working day on the phone, BT all day, plus an hour or two screen and WiFi on. If I have managed it OK (by killing battery stealing apps) I get about 50 to 60% left. If not, I can be down to 30% after that. That may not be enough for the rest of the day.
Why should it be a problem that people like to get a full day from one battery? It is not difficult, although you do need Root. Shame on Samsung that it is necessary, when it is clearly possible.

Lol I was seeking those who don't have issues. And was hoping for a discussion on how they deal with battery life without rationing or tweaking....not more complainers
It's a problem of unrealistic expectations.IMO When you look at the device it self and what it's capable of.
Yeah Samsung could have put a larger battery and fatter back on the phone but people would complain about that. Those solutions are available for power users as well. I think we are lucky to have a device where we have options to solve a basic issue other than not using functions. Apple and HTC do not have the same luxury.
Got to go........ battery is di
I'm a light user with the occasional call and sms and my battery last ~6 days. Phone is 3 moths old. However, I find that my battery usage is very dependent on signal strength. I usually get 4 bars and when that happens battery drains like 10% a day and when it is down to 1-2 bars then it can be 3 times that. I guess I'm fortunate that I get 4 bars most of the time in the office and at home.
I have a battery monitor widget installed and I must say that it makes me paranoid of using the phone and causing high drain. May uninstall it soon and use the phone as it should be used.
My expectations are pretty much met when it comes to battery life of the Galaxy Note. It lasts a whole working day. That's all I need. And for exceptional situations when I don't have access to a socket I have got a spare battery.
It's clear that the Note drains the battery really fast if it's in use. Just look at the screen . I also agree that it's annoying if the battery is empty after only 1/2 working day. But some people really have to blame themselves. If you don't turn off Wifi, Bluetooth and GPS when they are not needed it's no miracle that the battery is empty in no time. If you constantly check Facebook, Twitter and the like you have to accept that battery life will be significantly shorter.
For me the worst things are Bluetooth headsets. Not only is it annoying to have one more device that has to be charged but it also constantly drains the battery of the phone. Ok those wireless headsets are comfortable but you pay for it by faster battery drain.
hi guys, cool down.
the different opinions about the battery issue are resulting from the different way of using the phone along with the life style.
Some may need a bckp bat. Some can make sure they are always close to a power source ( if people spend a substantial part of the day in cars f.e.) Some even need an additional external power pack, as they are not close to power outlets all day.
That all makes sense to me but doesn't make me switching off all the nice features of that great phone. It is not an a piece for exhibition in a shopping window, it is for my personal use for business and/or leisure activities. It even connects me via video when I am far away from home, it connects me to the social networks and it let me professionally do my work and up or download all info I need from my corporation. I can log in via VPN to my workplace and edit documents by collaborating with colleagues through the cloud. It shows me the way through the GPS, if I need.
It entertains me in many different way if I want, It helps me to find a good restaurant.
I do not longer use a notebook computer or a tablet.
My Notebook computer could work hardly 2 hours with the same usage like my SGN.
So, I accept that this racing machine does need after some laps a pit stop for filling up the power.
Just love that tool, just love it

These are the kinds of responses I was hoping people people would post rather than more whining about battery life. there are plenty of those threads already.
I was hoping for a POSITIVE thread people could read to calm their perceived issues with battery life. BTW I don't use BT head sets for Music. Yes another thing to deal with charging where you cannot simpy replace a battery. I prefer the far better quality wired earbuds.
So Doze is supposed to minimize battery drain to almost nothing overnight or when the phone is not in use for a long time. How many people have actually experienced that? I'm not sure what to think, I lose about 1% per hour consistently overnight. That's without greenify or other battery saver methods. But it still seems excessive to me for such a hyped feature. I wonder if future hacks will be able to turn doze on in 1/2 hour instead of 1 hour. What have your experiences been?
1% per hour is pretty good. That means your phone would stay on for up to 100hrs which is more than 5 days. Are you complaining about that?

Doze only dozes applications from waking up the phone at their will, but still does periodic wakes. It will only make a big difference really if you had a misbehaving app in the first place.
Don't forget that even in the best case that Doze stops all activity from apps, you are still using power connected to the cell and or Wi-Fi, plus power to refresh the memory and other peripheral chips, so 1% an hour could be considered quite good.
Try putting the phone into flight mode over night and see if that 1% drain an hour goes, if all is well you should get around 1 or 2% power loss in 8 hours.
The other think to note is apps can bypass Doze and schedule wakeups regardless, this needs an update to the app for Marshmellow. So if you had an app that wanted to wake the phone every 10 minutes to download the latest adverts, it will stop under Marshmellow when Doze kicks in, but they could update their app to use a different API call and go back to waking the device every 10 minutes bypassing Doze. I strongly suspect that the Google Play store will start recognizing this API call and may start warning about apps that are battery drains, so the user can make a better decision, otherwise Doze will have a short term benefit as apps work around it.

Doze is working really well for me. Battery drain overnight seems to almost be non existent. I went to bed with 51% battery life on my phone. I woke up roughly 7 hours later and it was still at 51%.

Yeah I had only 4% drain after 8 hours overnight.

that was a great explanation, also I do think 1% per hour is bad since like someone already stated that I've had phones that would drain about that without marshmallow. Also those other people who replied I would really like to know how you get such little battery drain, do you guys have a lot of apps installed? I unplugged today around 5 am and woke up around 10 am with 95%. I have about 60 apps and 3 email accounts (1 yahoo which is set to sync manually).
Personally I am trying to sort my battery issues with this phone as some are getting great battery life (5 hours sot with over 24 hours off charge) while others are barely hitting 3 hours like me. Also I would think doze would be better than what I am experiencing.
How long have you had the phone for? AFAIK it can take a few days for Doze to "learn" how to optimize (reduce) battery drain. You may find it gets better over the course of a week or so. If you check the "detailed" battery stats (click the first battery graph) you should see little to no "awake" time overnight when you'd expect Doze to kick in - e.g see this link as an example: https://drive.google.com/open?id=1wjguaIIcGgUZn7w-KXnY3MJ0qTK0rUCWiA
Otherwise try as @PhilipL suggested and run in aeroplane mode overnight.
Doze is working as advertised here. On my 5x and my N5 as well.

It could be your location and the cell signal you are receiving, sometimes even if you have a good signal you still might be evenly served by 2 or 3 masts and the phone keeps swapping between them, if you don't have too good a cell signal, the phone will be using more power during standby. The only way to tell for sure is to put the phone into flight mode overnight.
One thing to note, you will only get the maximum screen on time if you use your phone a lot, i.e. all the screen on time is used during a 12 hour day after a full charge. If you are only using say 30 minutes one day, 20 minutes the next and so on, your total on screen time achieved will be less than many are saying they get, this is because more power is spent over time on background tasks and syncing, leaving less for actual on screen time. My previous Nexus 5 for example, sometimes I would go 4 days without needing to charge it, but my actual on screen time was only an hour or so.
Perhaps crudely speaking, 1 day of very light usage may see enough battery power expended on back ground tasks to see 1 hour sacrificed of on screen time.
Usually it doesn't matter how many apps you have installed, that in itself doesn't use any battery, of course if those apps are constantly pinging back home to some server, then that is how power is used. Doze will be helping with those apps over night and other quiet periods.

Thats the thing I get about 2.5 hours sot in about 12-14 hours and have to recharge before the night is over. Of course quick charge helps but I really don't want to rely on something like that. Also I'm wondering if wifi calling on will help with battery or will it be like the iphone where it'll just drain more battery? Gonna have to play with it and see what I can improve on. Also noticed that chrome has been using about 15-25% battery on any given day. I do use it as my main browser but that still seems excessive so may try a different chrome iteration if it keeps up.
Thank you to everyone that has helped and hopefully this can be a come all thread for people with questions about or problems with Doze.

Now you need to find what is draining your battery overnight when not in Flight mode. I suspect you will find either Google Services or Google Play services not releasing the modem or something similar.
When I installed Cerebus it asked to turn off battery optimization. My guess is that is Doze could be wrong though. It was the only app that asked. So far battery life is better then the N6 that I had a Amplify running on.

That is pretty bad if Doze is on given that 1%/hr is a widely accepted standard pre-marshmallow

Might be a standard if everything worked perfectly, which I have yet to see. With this new architecture, you are guaranteed it. I love it.
I lost about 1% in 3 hours last night with WiFi calling on. Maybe it has to do with poor coverage. Last night I did end up with 3.5 hours sot which I think was my highest. So in the past few days I have factory reset and turned on WiFi calling.
Now I need to optimize my browser usage, chrome was talking more than screen was ~20%. Using #nochromo now and not much better.
Battery went from 66 to 64% last night in 8 hours.. #dozeisdope

Hey folks,
Just curious if anyone has seen battery life improvements since the most recent wear OS app update?
Initially afterwards I saw normal battery life. However, I ended up being without a charger Saturday night due to an unplanned inability to drive home from a friend's house. This resulted in me powering down the watch overnight, then running it to dead on Sunday. Recharged overnight, and today this is what I'm seeing for battery life...
This is my normal configuration (BT connection to phone on, WiFi on, GPS off. Screen always on, same watch face I've been running for 5 days).
Interaction was at normal, or maybe slightly more than normal level today, as I was in training class so I responded to a couple things on the watch that I normally would have used phone for.
Really just curious if anyone else is seeing a change, since I can't figure out what, if anything, I did to make this happen. I'd love to see it continue, as it's about half the battery drain I'm used to seeing. Usually get about 22 hours estimated up time, something like 4.8% drain per hour. This shot shows steady drain of 25% over about 11.5 hours or like 2.2% per hour...

And you saw the change start since the last update? Have you run it fairly low since the improvement? I plan to charge tonight, but curious if it's actual improvement or a reporting error (so it'll die at like 50% or something).

I've run it down to around 30% it took over 2 days lol and charged it back up I don't think it's a reporting error

Nice!!
I'm totally baffled as to how you guys are achieving this kind of battery life. I've had the watch for seven weeks and I've never eked out more than about 18 hours.

I've been using this guide since I first got the watch for battery saving setup:
https://forum.xda-developers.com/an...-battery-tip-wear24-lte-aw-watches-3-t3729680
This initially got me the roughly 22h up time and 5%ish per hour drain.
The only things I'm aware of that could have a (slight) chance of triggering this recent improvement are:
Update to wear OS software
Ran watch out of power (possibly giving the battery better calibration data?? Forcing a reboot after the update).
As of right now today isn't quite as good as yesterday (76% left at just over 8h off charger, so 3% per hour). Essentially identical usage to yesterday in same locations.
I dunno.
Thanks. I've seen that post. The guy swears by airplane mode. But if I have cellular disabled and wi-fi off, I'm not sure why it's also necessary to put the watch in airplane mode.
I'm sure that some of my watchface choices have an effect on battery life and I'm willing to accept that (and save the less-efficient faces for days when I'm mostly home), but I should still be able to get through a long day with power to spare, which is not always the case.

I do run airplane mode 100% of the time. No haven't really tried without it to do a comparison.

Reportedly it still polls for Wi-Fi if you have it disabled. They state this stops in airplane mode saving a bit more battery.

The Wi-Fi polling may be part of location services?
I'd be willing to try airplane mode if it didn't put that little plane icon on my watchface.
battery improvement
I noticed my wear24 battery time got significantly improved today.
Is anyone else seeing on their watch? imgur.com /a/aUSCEQl
Shortly after I originally posted this, mine went back to what I'd call typical. However, the last few weeks it's been better again. I'm usually seeing between 50 and 75% battery remaining after a 16-18 hour day off the charger now. Seems to be better with facer and pujie black faces thanc with watchmaker, but the difference isn't huge.
my moto 360 first gen
only last 4-5h now. and turns off at 37% great
maybe need a new battery. buying one for 11€ hope that gonna fix it
Anyone else's wear 24 battery starting to go bad? As of the past weak I can barely make it 12 hours with minimal use. It's as if the battery life has been cut in half.

Occasionally I get bad days, but, as an example today with minimal use I've had it off charger just over 11 hours and currently at 60% battery left. I'd say normal is around 20-22 hours usability.
Newest update has increased my battery life dramatically since a few days ago! Others are commenting on Reddit about it.
Same here. Getting 2 days of battery life with Airplane mode On; then Wifi/BT on (3G/LTE off).
