[Q] Standby time?

Hello all, I'm planning to get myself one, when it will appear in my country... Question is, how much battery consumes in standby? I mean, number of hours before it is under 5 percent and needs recharge, from 100%. For example an Ipad has 30 days, I've read numerous reviews that show EEE Transformer in a bad light, with sleep mode eating 20-30 percent per night, or 30 hours standby(Engadget) at most. Rest of reviewers don't point to standby time, only to battery life, I want to know if it dies after 30 hours of sleep mode. WiFi on and without, it's good to know. For example My Galaxy S with WiFi on and a weather app refreshing every hour, with Gmail, has 2 days before it drops below 30%, I don't talk that much on phone and never use Internet browsing on it.

I can't compare to Ipad, but overnight the Asus drains about 5 to 10 percent. That is wifi set to switch off when screen is off. Second about the Endgadget review, my asus lasts on one charge 2 days (48h) normal use, that is normal usage: playing, web browsing, reading, overnight screen off, etc. So you see 30h of sleep mode is very very very wrong because not optimized/too many apps/wifi on.
So I'm no longer reading reviews of the asus, but reading/playing on the Asus
Hope this helps,

but still it looks not that much compared to apple ipad2, which is kinda sad. I was kinda hoping that this device outperform ipad2 in battery too...

some reviews claims it gets close (1hr difference) and some say not even trying (6hr difference) against the iPad, but I think some of them were using live wallpapers which drain battery pretty fast. It has never stated to be better than the iPad though unless it was with dock.

I dont know if it lasts so much as ipad. However, in my exp. with ipad1 when it had ios 3.2. battery was lasting ages, almost no loss overnight as you point out.
After updating it to 4.2 battery was really drained hard. It was difficult to have it running more than 2/3 days on a row. And the difference came on non use periods. On continous use, it was lasting about the same.
This is, are you sure ipad is doing 30 days?

The only thing that lasts almost a month in standby time in the android world is the galaxy tab.

The battery is definitely not as standby friendly as the ipad. My mom has the first gen ipad and it uses basically no power in standby. On my transformer, I get a drop overnight (8 hours or so) of about 2-3% with wifi off. I use setcpu with a screen off profile to restrict the cpu to the minimum frequency.
It's disappointing because my droid incredible, with a 1500mah battery (1/4 of the transformer?) doesn't drop at all overnight in airplane mode.

I just turn mine off at night b/c I have no need to sync stuff overnight. For that matter I also turned autosync off by default for most apps even when it is on. Basically uses 0 battery that way (maybe 1%). I know that doesn't work for everyone though.

I pulled my TF & dock off the AC on Tuesday at about 7:45AM, both fully charged. As of an hour ago, I had about 72% juice left in the TF (dock is drained). It's been docked the entire time. I've only used it lightly the last 3 days. I did download & install 3.1 during this time as well.

How long your battery lasts with heavy use? VOTE!

As stated above, I'm curious what the answers will be.
We obviously can't define "heavy use", but I think everybody gets the point

I'd like to ask the 7-8 guys how they do it?

I use auto brightness.
Also, when I got the TF I did the whole break-in thing. It was in the manual.
Now, if you want to get better life you can reset your lithium ion battery. Use it till its below 5%, maybe even go to 0%, then charge it to 100%.
Do this atleast twice back to back. You should see your life grow.
Also, never over charge it, and never leave it charging at night. Even though some people will tell you it 'stops' charging once it hits 100%, it actually goes to trickle, and trickle or not, its still over charging it.

Thanks for the answer,
I unfortunately don't have the manual with me, but true, I just got the tab yesterday. So do you think in time it will improve? What is that break thing you mentioned?

Mine has also got better only thing that kills the battery is playing Galaxy on fire 2 other than that i watched two 2 hour long movies and still had 40 % left

Manual says "to prolong battery life fully charge the battery for up to 8 hours when using the Eee pad for the first time and whenever the battery is fully depleted" Often wonder where you get these post that say don't leave it charging for more than 2 hours.
Auto brightness is really dim on my old eyes
BTW I have a dock and get a lot more than 7 or 8 with it ...very close to the 15 or so they say ..it is according to what your doing...if your playing games, watching flash or movies your mileage will vary

Same here, I usually just watch movies, (occasionally getting distracted by some tower defense game), but apparently my overall usage is due to the screen brightness. I had it on autoadjust for a while in the beginning (lasted like 8 hours) but then I don't like (is there an adjust option for autoadjust? it'd be a lot better if it made it just 10% brighter than it usually sets it..) the autoadjust, so now I usually have it on like 60-100% brightness and I still get 6-7 hours on it. Then i just dock it for another couple of hours.

Hm... too bad I like bright screens
So maybe that's the reason mine only lasts 3-4 hours :S
We'll see later on, maybe it will improve!

Wow. I have mine cranked and it lasts well over that. Closer to 6 with consistent video watching.

i mostly use mine to browse online and music etc,i get around 9 hours with auto brightness
*added*
i used systempanel to monitor when i sleep to check usage,its between 1~3 percent for the cpu, battery life stays flat lined. cpu activity averages 30% while device is at 100%. i use advance task killer and juice defender and disable connections and sync etc.

well one thing for sure, my mifi died before my transformer died, so i roughly say 6 hours ++. when in music, it saves a lot of battery.

2 hours is silly. Mine takes at least 2.5 to charge to 100%. I'm not sure where you've read that, but don't believe it! lol.
Li-ion batteries are great because they are extremely flexible and charging them like 5 times a day isn't a bad thing like it would be with an older technology.
But they are still susceptible to overcharge issues because they generate heat when charging, and that heat changes the composition of the battery, which makes it last less and less over time. That's why li-ions hold roughly 50% of their charge after 1.5 years of use.
And that's why one shouldn't overcharge it.

about 6~7 on stock..just recently tried prime 1.7 so will check for any changes

Does Netflix count as heavy usage? if so then I get about 8 hours

I use mine to browse and to remote desktop to my PC. Sometimes i use gchat and other times play a game or two. I get around 7-8 hours from the eee pad only. With the docking i get much more.
I use auto brightness, and wireless off when screen is off. This way i can leave my tf up and running all night and is ready to be used at any time. The main power consumption are the screen and the wireless on my usage profile. Both together consume more that 70% of my battery.

Is it possible to switch off the wifi automatically when the screen goes off?

Yes, of course. Go to wifi-properties, then choose extended (on German: "Erweitert") at the top right and there you can choose your setting.
(I've got a german TF - there it is "WLAN-Einstellungen"->"Erweitert")
With auto-brightness and wlan-off on screen-off 9 hours is no problem.
Great Tablet

I run Clemsons V4 Final, no dock and have the screen timeout set at 30 minutes. I didnt pay attention to the recommended battery stuff in the manual. And usually leave mine on the charger all night to be sure I start the day at 100%. I use my TF all day for work, taking notes, surfing and so on. I generally get home with 40%, if I dont play Angry Birds. I have played just music for 8.5 hours continuous with a 15% drop in battery.
Not iPad performance but still a keeper.

I put 6 hours of HEAVY use, but I usually get a full day's usage out of it since I keep my pad tethered to my charger at my desk all day at work.

tried the break-in charging thing (drain to 0% then charge it for 8-9 hours). My battery life changed drastically. Did it only once but ill charge it like that again when it depletes to 0%. It running now on its 3rd day with minimal to moderate use (28% as I am writing this). Will post battery drain per hour once done with the 2nd charging

Higher battery draining after 3.2?

Hi
I do nont know but i have strange feeling that after 3.2 update my transformer drains more power. I mean the battery is draining faster than before the patch? Have you noticed similar thing? (i do not have the docking station)

I seem to be seeing that as well, and the wifi signal seems to be weaker. Not sure if I want to put in a problem report.

Wifi signal is weaker for me too, but the battery's been just fine.

I noticed also that the standby battery wasn't as good on 3.2 for me compared to 3.1. After messing around with the device for a while I found that even when the battery saving mode was checked, the keyboard wouldn't wake up the transformer but a touch of the trackpad did. I thought that there might be some background service that was stopping the transformer from going into deep sleep so I used advanced task killer to kill everything and the device would go into deep sleep. Also, I read on another forum that it might be a syncing service for picasa. I turned that off, killed everything using advanced task killer again and battery life now is equivalent to what I got in 3.1.

I feel my batterie last longer. But I have to measure it first.

I've done some (informal) tests, and I'm getting about .5%/hour consumption on standby after 3.2, where I was getting about 2%/hour consumption on 3.1 and earlier. This is just the tablet, mind you.
So, 3.2 has significantly improved the situation for me. I haven't really measured in-use as closely, but it seems pretty much the same (which is about 10%/hour consumption if I'm really using it).

+1 same here

My Wifi is very good
The battery is good

My wifi has improved by a bar and the battery seems a little bit better. But that's only if I don't struggle with trying to get on wifi.

Maybe during use but if anything my standby time is longer.

Battery seems the same to me, as does wifi.

That has been my experience also.

After 3.2 mine seems to be draining the battery quicker with wifi on & surfing. I might get 4 hours of continuous surfing if that.

Me too, last night I have 95% of battery before switch off to the standby mode (screen off with the wifi sleep), but this morning TF has just 72%.
I am now testing it. I switch off the wifi function first, then switch off to the standby mode.
My friend also notices this problem after upgrade to 3.2...he said 52% to 17% just one night sleeping...wow...what a unbelivable report!

Look at the battery use reports on your settings and see what is taking up a good chunk of your battery life besides screen and wi-fi and you may find a problem. For me, I saw that Google Maps took up 25% of my battery and I only used it for five minutes (it said that it was on for over two hours). I tried force closing and nothing worked until I uninstalled the updates for it and haven't turned it on. Now my battery life is much better. You may also want to check applications that are turning your wi-fi on to update themselves, like e-mail and facebook apps, etc.

Check for Google latitude. It appears to keep GPS running even when TF turned off.

I am on 3.2 since yesterday (Belgium) with B6 dock.
Fully loaded and half a day later in standby 63%.
On 3.1 this would have been 83%.
Battery drain is much greater on 3.2 on my TF!
(Damn, I hate the keyboard lagg whilst typing this)

Mine has been better since the update and I have the ****ty B4O dock. I charged mine on Sunday then went on vacation with it Monday, on way home now and only charged it once on Thurs one the dock finally drained and the tab was down to 60%. Seems like they did something to help as that was unseen before, I had to charge it daily.

I also notice faster battery drain after the 3.2 update.
when I went to bed last night: Tablet 97%, Dock 72%.
This morning (about 9 hours): Tablet is the same, Dock 30%. WTH???

I noticed it today. I leave my dock on the Transformer even when its off and folded. I used it a few times to in the span of 2 days tying into a journal. Today the dock was at 3% Screen at 98. Im guessing its feeding power to the screen. The only settings i have different is screen always on. I shut the screen down when im done using it, or set the Transformer aside or off.

Extended Battery

Anyone know where to get an extended battery? Thanks.

I can't even find a place to buy a regular battery for the phone. I'm not sure if I would need one, but it would be nice to have. I'm in the habit of charging it the last hour I am at work so no matter what, I'll never run out of battery even if I go somewhere straight from work, but a spare battery is always a good thing to have.
I have a wild guess as to why not.
I noticed this phone battery has the "near field communication" labeling on the BATTERY. The other phone that I'm aware of having NFC, (the galaxy s2) does NOT have this wording on the battery.
Why did I notice this? I randomly read that there is an SD card manufacturer that is putting NFC chip's into their microSD cards, and even some ipod cases are getting NFC chips built into them as well.
I don't know too much about NFC, but with the labeling being on our battery, and not the S2, I kinda think our NFC chip is actually in the battery, and not the phone itself. If an NFC chip can be put into an SD card or case on a phone that never had NFC to begin with, I don't see why it couldn't be put into a battery, especially since one of the terminals might not even be for power, but just for an NFC connection.
That's my theory, I could be wrong!

you're probably right. This is how it is with the Galaxy Nexus, also built by Samsung. I hadn't noticed the label, but I also wasn't looking for it.
I'd be curious to find out what an "extended battery" for this phone would look like. I'd be all for it so long as it kept NFC and didn't bulge out of the back

I'd be interested to find one. Being on a stock rom and standard battery, my battery drops about 5% in five mins just checking Facebook. GPS drains it another percent per min it is in use. Half way thru the day my battery is dead. It really sucks having to carry around a charger. I'm also using juice defender and other tweaks I know to save battery

I'd bet you a waffle cone your screen brightness is set too high.
Forget most of those "battery defender" apps, especially if they are those stupid task killing applications.....a program being in active memory is not necessarily actually doing anything, which means it is not using your battery, and if it gets killed, if the OS needs it open for any reason, it having to be re-opened will just use cpu cycles anyway
I'd agree with most people that using the automatic brightness option is very annoying, it's really sensitive and it also tends to make the screen not be bright enough. Having said that, using any of the many available brightness widgets can be a very good thing.
The stock one is not so bad, personally I've been enjoying powerful control, http://goo.gl/2vZXl but I've had great battery life and easy readability if I use the brightness setting where it looks like a half moon.
If you're outdoors in the bright sun, you'll need the screen to be as bright as possible if you want to read it, but otherwise it's fine. The screen brightness is always the single biggest battery usage factor.
Personally I've always disabled the haptic feedback as I think it's annoying and I'm sure that using vibrating alerts is also a huge battery drain.

My screen brightness is at zero without automatic brightness on, and im not using haptic feedback. The phone battery is fine if its just sitting over night, but as soon as I turn on GPS to use maps for 5 mins or to check facebook the battery just drops a % every min. So i guess the phone is fine if Im not using it, but then whats the point?

You're exaggerating.
I've never had a phone battery drop 1% per minute.
Look man, I just spent 5 minutes playing music at max volume, while getting directions to 8 different places in google maps, sent two emails, downloaded a new app from the market, and received one text message.
Battery level after all this? Still at 100%. Does that mean I can do this an unlimited number of times? No, it does not.
Frankly, I don't believe you. I've used this phone, and my previous phone for playing movies at full screen brightness with the audio being played through bluetooth to my stereo headsets. Does it effect the battery status? You bet it does.
Two weeks ago when I last played a snes game on my phone I did so at full screen brightness over bluetooth to a ps3 controller. When I wasn't playing the game I was sending or receiving text messages and had vibrate on. I played super metroid from the very beginning to almost through the end of the game. When I play snes games on my phone I tend to use quick save and quick load and frame skipping very commonly, effectively letting me do things "perfectly" but this is a lot of saving and loading and running the game even faster than how it normally is. I started at 2, and the next thing I knew it was 6:00 and I was supposed to meet a friend for dinner at 6:30.
But for crying out loud you are saying you can drain your battery from 100% to zero in less than 2 hours.
I'm calling shenanigans. I don't think you could even do that intentionally, unless you sat there and forced the phone to vibrate the entire time.
Phone batteries don't last for days like they used to. Batteries have not changed too much in the last few years, but the things phones do, and the screens they do them on certainly has. Stop expecting your phone to last over the entire weekend even when you actually use it.

Something to keep in mind:
When this phone hits 100%, it STOPS CHARGING. Even plugged in, it will no longer be drawing power into your battery, yet it'll still be running on battery.
If you plug it in when you go to sleep, it finishes charging within 2 hours, then it goes 6 hours idling on battery power but it still says 100% until you disconnect it. Then, while you're using the phone it'll adjust as you use it until it gets to the right level. This is likely what you're seeing.
If I use my phone from the moment it finishes upping to 100%, I get great battery life. I get great battery life in general and have been happy with the phone.
Of course, this might be a totally different issue where you just got a bum battery. But it's something worth considering.

I don't believe this is true. I hate to constantly be a naysayer in this thread, but this didn't seem logical to me so when my battery went to full, (when the battery is full, unplug charger text showed in the notification bar) I kept it plugged in and set it to play a couple tv episodes on full brightness while I did laundry and made dinner.
Two hours later, I first looked at the battery status while the phone was still plugged in. As expected, it was at 100%.
I unplugged the charger, waited a couple minutes, and checked again.
Still at 100%, which completely makes sense because I've never had a phone that behaved as you've described.
I also would have noticed the battery dying very early, *every single day* because my habit for the last week or so has been to plug the phone in when I go to sleep. I have an app called syncme that pulls files off my computer such as music and video while I'm sleeping, and on average it transfers about 6 gigs of data this way, every single day.
I don't know if you've ever transferred 6 gigs of data on a phone via wifi, but yes, it's not exactly battery power friendly.
My phone's always been 100% battery when I leave for work, just like my last phone was where I also plugged it in at night.
Just saying!

Actually he is pretty close to the way it operates. The way your phone gauges battery life is similar to your car with gas. When the meter reads 100%, it is really more like 98%. When the battery reaches true 100%, the phone will stop charging the battery (but will run off of USB power, not the battery). They do this to account for small variations in the many variables that affect a battery's performance (like temperature). Likewise, your phone will read 0% before the battery is truly completely drained (this is also to protect the battery - they don't like being charged to 100%, nor drained to 0%).
This could also greatly affect your previous test on battery performance. To get a more accurate result, let the phone drain to about 60%, then test the time to drop a percentage point.

What you are talking about is a suggestion that the battery meter doesn't necessarily update it's strength meter all of the time, and you even say that the phone runs off the plugged in power at this point.....

Before you discredit anyones post, you should understand how many battery chargers work, and the importance of them shutting off following a complete charge. Here is a quote regarding Li-ion battery maintenance :
Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
Many chargers have this feature built in to avoid any overheating and/or damage to the cell. I'm not saying this is the case because I have not tested whether the battery charging circuit in this particular phone, or it's charger operate, but I will say that this has been the case in MANY of it predecessors.
That being said, I think an extended battery would be a welcome addition to the options of this phone. Mine too only lasts a day at it's best. Perhaps not 1% a minute...but then again who knows?

[Q] Worried about battery, new tablet

I have only used my Galaxy Note tablet a few days, and I am probably using it approximately 5-6 hours tops. It is needing recharged every day! It takes hours to charge and then I only get 5-6 hours usage? Is this normal?
I would appreciate any response.
Thanks.
Galaxy Note 10.1

Try going into setting and then battery see which application is draining the battery and get rid of it.
Note has one of the best batteries around but if you use non stop for heavy application like gamming you should get between 8 - 10 hours of actual usage.
If not then may be there is an issue with your charger or battery get it checked and replaced
Also Note takes a long time to charge around 5 - 6 hours

Hmm.. I use it and get about 8 hours +/- depending what I do with it. I normally use it to take notes for about 5 hours (around 3 hours of actual note taking, 2 hours of doing scratch work for homework on it), and I'm browsing Reddit for the rest of the time. I've noticed that I've had to charge it more often lately, but I've been using it to watch Netflix mostly in the last couple of days.
In my experience with the Asus Transformer, I had to charge almost everyday as well because of my high usage. What do you normally use it for?

A day's heavy usage is normal.
Charge from 0-100% takes about 5 hrs for everyone.
In simple terms, the Note 10.1 has a large capacity
battery that takes a while to charge. Rechargeable
batteries lose their ability to hold charge over time,
but that time is measured in months and years.

I am not sure, maybe I am reading this battery meter wrong. When I go to settings and open battery, it says "51% discharging" and then below that says "15h 12m 59s on battery."
We are mostly using the tab for web surfing, and watched a few Youtube videos. I don't believe anyone has even watched a full show on it yet. It has only been in use since Thursday night. I am not sure what to think.
Doesn't the 51% represent how much battery life is remaining? And what does the other stat (15h 12m 59s on battery) represent?
I appreciate any help or advice.
Also, The only items it shows below that is Screen & Device Idle. Screen says 99% and Device Idle says 2%.

99% usage for screen is quite odd. Maybe try turning brightness down or trying the power saving option for screen. Also, and this may sound silly, but if you haven't rebooted it, that is worth a shot, sometimesthings just drain until rebooted.

To answer your questions
51% is the amount of remaining battery.
15h 12m 59sec is just what it sounds like. It's the time the tablet had been off the charger.
Most of the time your screen should be the highest. Here is what mine looks like. It's been a light day.

Please help me figure out if this kind of usage seems appropriate for battery drain. I am keeping a little log to see how fast it is draining. I just cannot understand if this is normal. Here is a small sample for this evening to see if it seems normal. I only been surfing some, no watching anything.
1109p at 99% battery
1130p at 94% battery
1155p at 90% battery
under settings, battery, all that says is screen 100% no other items listed below
Is it normal to get 5 or 6 hrs then have to recharge even if you are just surfing? I thought people went for days without charging this. I have never owned a tablet before, but I never have to charge my computer or phone this much and I use both for more time than this and not had to recharge this soon.
I am just trying to understand if I have something se tup wrong, or have a faulty tablet.
I truly appreciate all the help from everyone. Thanks.

Have you tried changing the brightness to about 30% (about the same as what I have it on and I get about 3-4 days charge with light usage)? Also rebooting, uninstalling recent apps, enabling/disabling power-saving options?
If nothing else works, try a factory reset and just use it like normal with no extra downloaded apps from google play. Try that for one charge and if it's still bad, there must be something wrong with your unit.
Would you be able to take a screenshot of your battery status window? (hold spen button and hold spen on screen for 2 seconds to take screenshot). It could help us determine the problem. If you could get screenshots of both the main window listing the things that have used battery, as well as the window after you tap the battery graph, that would be great.

Mate, I don't honestly believe you have a problem... I use my tab for around 10hrs/day and I need to recharge it... I do use it for mostly video files...
I also have the 3g version. What's yours? If it's 3g and you are in an area where you don't have a good signal then the modem will be looking and consuming battery power...
Even though this tablet has a large battery, it is usually used up within a day or 2... Try leaving your laptop on all day, it won't last too long either...
That's the main difference between a laptop and a tablet (even if the laptop is in hibernation it will still kill the battery eventually).
