Can one battery last 15 hours of ebook reading? - Touch HD General

Just wonder how long can the battery last on airplane. I have lots of ebooks that I would like to read on airplane but wonder if one battery alone is able to last 15 hours.
I've considered buying a airplane charger but worried that not all aircrafts have the charging facility.
Good idea to bring at least one spare battery for the trip?

I suppose it is based somewhat on the battery life one is experiencing, but I am finding I get a full days use with 5-7 hours constant use of internet, MMS and phone. That's a lot of high power use topped off with a couple of hours of playing music and another odd hour or two of ebook, much more than the backlight of an ebook alone.
My experience tells me I would not hestitate a minute to say you'd have ample power for a day of ebook use.

5 to 7 hours of constant use and still lasting a day sounds good. On the airplane, with flight mode on, I expect the drain to be much less severe, so I guess you're right about it only having to produce the backlight.
I guess the answer is there should be no problem then. Cool.

That's even more assuring. Thanks for this info.

sure it's £50, but you might want to look at getting one of these: http://www.expansys.com/d.aspx?i=173540, it's basically a power brick that is supposed to hold 3 charges for your device. The upshot of this is that when your device is running low, you connect to the bank and it starts charging. This means that you have backup power and you don't have to turn off the device, remove the cover, change the battery, replace cover, turn back on!
It's certainly up there on my list of stuff to get once mine arrives!

I have always one of these with me, so I can charge whatever is needed ...

Battery Power on Universal

Sorry, i'm bit new user for Universal, But i think my universal bettery drain faster than last Alpine. I want to ask other user, how often you charge the universal battery?
Thanks in advanced
Depends how you use it.
If im away from home at a weekend and hardly use my device - it might use 25% just being on standby for over 48 hours.
On a daily basis it might be on solidly for 2 hours throughout the day - when i get home battery might be down as much as 50% - thats making calls, texting, listening to music, bit of surfing on net, occasional game of Bejeweled.
Figures quoted by operators are 4hrs talk time, 240hrs standby - these figures mean nothing though.
Who's going to leave their device unused for 240hours to test it!!!
So in answer to your question charging at least once every two days perhaps every day depending on use.
Matt
@ matt1971:
Thanks a lot for reply, I'll figure it out. And test in couple days ahead.
my uni is always on charging as i use it to connect my lappy with that but it dies after 30% of its battery think it is near on its last days .
Hmmm... sthe battery is long enought if on stand by mobe, but if i play with it, it drain fastly. I'll looking for why?
Anyone can help? Or any sugestion?
my suggestion is to refrain from plugging it thru the usb frequently. my battery problems surfaced only after i used wm5torage a lot.... others may say that it wouldnt matter, that poly ion bats should have no memory effect, but i've been bitten twice and i wont take the risk anymore..
Question?
Hi,
Do you use Internet?
Cheers, Leo

Hello everyone,
Just got an XDA Exec yesterday with two batteries. However, the both charge to 85% and don't move forward. They've been on the AC plug for over three hours now. Am I missing a config setting or something?
Thanks in advance!

No setting needed to charge the battery until 100%, hardware failure i guess, any warranty for replacement, I mean maybe the unit, coz it happend on your 2 battery
cornelius,
Thanks much. It MAY be that these batteries have never been fully charged; I left them on overnight and although it took A LONG TIME to get over the 85% hump, they eventually got there.
battery charging
you do need to charge the battery first time for a good 16hours - i've gone for a 3200mah Lithium ion instead of the standard 1600mah - got it off ebay for £16 with a new rear cover as its really thick!!! only problem now is the brick won't sit in the car cradle ;-)
Robegee,
Does your unit report battery % correctly, or does it stick at 100% all the time? I've read (haven't tried), that these aftermarket batteries don't report drain properly.
Just curious... I'm thinking about purchasing an extended battery, but want to know. Where did you get yours from?
Thanks.

Battery Life

Rather than clogging up other threads with my battery experiences, I thought I'd summarise where I'm at, and see how other people are doing with their battery life.
So I started yesterday on a full charge, and by 2ish the phone was dead. I used it fairly heavily, but wifi was off. I don't think I made any phone calls, and didn't use gps. It was mainly messaging and using the xda app. I had changed my screen brightness to auto the night before, so thought this might have reduced the battery life.
I then left the phone off, and charged through till just before 5pm. At this stage, the phone was up to between 90-100% charge. My intention was to see if I could get through to this afternoon on this charge. Last night I made a phone call for about half an hour, and used gps for about 10 mins driving in the car. Other than that it was a bit of messaging and browsing, but not heavy use by any stretch of the imagination. I had wifi off, facebook sync every 4 hours, and screen brightness set to about 50%.
This morning I woke to less than 10% charge on the battery, so have left the phone at home charging, and I'm back to my hero...at least for the morning.
I must admit, I'm starting to get concerned, because I really don't think I'm using this phone more than my Hero, and I could easily get a day out of it (unless I was going for a long run using some kind of gps app).
What are other people's experiences? I'm surprised I'm not hearing more about this, and I'm hoping mine is just a one off!
**UPDATE**
Today, 12 hours after taking my phone off charge, I have just under 20% charge remaining. The phone is now on it's fourth cycle, and although I haven't used the phone quite as heavily as yesterday, I have still used it quite a bit and have had WiFi on the whole time. This is still not amazing battery life, but it is still much improved. It definitely illustrates that the battery may take a few charge cycles before it optimises itself.
My first full day was yesterday.
WiFi on all the time. Screen brightness set to automatic. Twitter and facebook refreshing every hour. Weather every 4 hours.
Unplugged the phone at 7am, 100% charge.
During the morning I flashed the phone twice (due to the proximity sensor issue) so it probably recieved an extra 10 mins of charge.
Following the flashing, WiFi went straight back on so I could download all the apps again, and resync sense and all the contacts. There was some playing of games, some use of Google Goggles (so camera use there) and some web browsing.
By 13:00 I was down to 90% battery - which was pretty good I thought.
Through the afternoon I didn't get to use the phone much apart from a couple of short gaming sessions.
By 17:00 I was down to 80%. I got home from work and played around on the phone until my wife got home and we went out for a meal. The pub we were in had no signal, and I didn't really play around with the phone.
By the time I got home and went to bed, the phone was probably around 65% full.
So not a heavy day of use, but not far off a standard day for me - so not too bad as far as I'm concerned. Certainly about 30% better than my Touch Pro2 was!
I think we need to define a consistent way to measure battery life for Android.
Something like ACID test for web ... Quadrant for benchmark ...
I don't know, maybe we can agreed on something how to measure it. Or build an app to simulate phone usage which user should run it continuosly and then at the end got the result: Your battery life is rated 4 hours, 10 minutes straight using this test.
Probably not the best measurement, but it should give us a "number" to compare with other devices.
I can only suggest (I am not a developer), but I believe there are a lot of talented coders here in XDA which should be able to build this kind of "standard" app battery measurement pretty easily.
Somebody is recommending 3-4 full charges cycles for battery optimization. Do you think it will really help?
Battery is really deal breaking issue for me.
very helpful thread.
as mentioned few post earlier, there really should be a battery benchmark tool.
so was your wifi and/or 3g turned on the whole day?

My friends also lasted over a day with pretty good use, there seems to be better results with the brightness on auto...from what I have picked up on the forum...maybe a test is need to see how much difference there is between full brightness on one battery charge and auto on the other.
Yupe, the battery benchmark should not be so complicated.
Start the app with 100% Battery life
Some options in the app (for features that might NOT be in an Android phone or might not be available at the time?):
[ ] Turn on Wifi
[ ] Turn on GPS
[ ] Turn on Bluetooth
Set the app to WAKE all the time, display turned ON all the time of the test
Set Keyguard to OFF (device will not be locked)
Set Brightness to AUTO
Set all speakers to SILENT
Set vibration to OFF
Then loop until battery down to 5%, perform the below tasks in sequence:
* Play movie for 15 minutes [speaker muted]
* Browse to website??? be careful not to overload the website
* Doing arithmatic
* Doing 3D
* Play MP3 [speaker muted of course]
As soon as the battery down to 5%, app stop and display result ...
And of course restore all the settings.
The app should use generic API that is supported by Android, not some hacky wacky if you know what I meant.
Please if someone can code this, that would be very nice! Standard XDA Battery Measurement app for Android!

the app should log the result too.. since some phone is dead by time 5% due to calibration..
@Dazultra2000: I would almost trade the proximity sensor problem for the battery life you're getting!
In any case, I'm gonna leave my phone charging till half an hour after the green light comes on, then I'm gonna try another day of normal usage. I'm going to turn wifi back on, as I usually would, and set screen brightness to auto.
With my Hero I used to go for runs using a GPS app to log the route, I'm not going to bother trying that with this phone until I'm sure I can survive a day.

I don't know when you wake up but that could be like 14 - 15 hours that you mentioned which possibly isn't all that bad (plus the extra 10% you had remaining). Personally I want to see what it's like when you unplug it at 8am, not at 5pm the night before since I can't see any good reason not to leave the phone charging over night anyway.
If you then manage to get about 10 to 12 hours or so then there probably isn't much issue. Granted you weren't using it while asleep so the battery shouldn't drain overly quick but I wouldn't want to use your test as an example of a days use.
Thanks for the info but. If I was you I'd just have a car charger too if you like to use GPS...I can't see any reason not to.

Yeah, I would normally charge overnight, but since I had given a charge through to 5pm I wanted to see how it lasted....see if I could get through 24 hours. I wake up at 5am, so that was around 12 hours, with only 5-6 of those hours being time when I would've actually been using the phone. This is also bearing in mind that I had started yesterday on a full charge and the phone was dead by 2pm.
The GPS thing in the car was only to do a quick test, literally 10 mins. I need to buy a new car charger with micro USB, but I just made a note that I had done this because I knew it would affect the battery.
Anyway, we'll see what today brings.

Looking forward to it.
And yeah, for me personally a "days" charge really only needs to equate to about 12 - 14 hours. Thats probably the longest I'll go without having a charge anyway unless I'm camping or something in which case I'll likely fall back to a Nokia anyway.
Hi, just to add my experience with a complete different phone e.g. iPhone 3GS (developing apps on it, now switching to Android ):
Charge at night till 8 a.m. so 100% then usually in a day:
- Go to office, read/write emails, surf a bit on forums, blogs and so on
- Make call up to 30-60 minutes per day
- Play some games, test our application/games on it (so connect and receive some extra charge)
- Use WiFi at office
- Use Google Maps up to 15 minutes per day
- Back at home at 8 p.m.
- Use again emails and surf on web for 30 minutes
Around 11-12 p.m. it has less than 25% of battery, so 14-15 hours of usage drain battery up to finish it, not to mention that I'm forced to switch off push notification because they drain my battery in 5 hours!!!!
So just to say that, no one is perfect, and this devices today really do a lot of stuff, I think as Smigit suggest 12-14 hours are acceptable.
Have also tested/used iPhone 4, I don't seen any big improvements on that side.
Just my two cents...
praying for decent battery, please please please!
My HTC legend is pretty poor really, but I can live with it. If DHD is worse I don't think I can pull the trigger.
There is a thread in th Legend section about 1800mh HTC batteries (from another phone) that fit the Legend. Maybe there will be an option to do something similar with DHD.
I would pay £50 more for a 1500mh battery - why did they put the smallest battery in the largest screen?

No the battery doesnt fit with the Desire HD, if you watch some pictures of your 1800mah battery and than go and take a closer look at the DHD's battery, you will recognize that the pins of the DHD-battery are on its side. the pins from the Incredible Battery are on the bottom.
In 2 hours 30 min heavy heavy heavy use, the battery dropped 20%.
Will do a full day test 2 morrow.

[Q] Battery Life?

So Samsung Omnia 7 or Focus owners, how is the battery treating you on the phone? I'm going to switch to AT&T for this phone, but I want to make sure battery life is good too on it!
Based on your "average" use, how much battery life do you get? You can make it like 1 and a half days? Barely make it through a day? 2 days??
Thanks everyone! Vote in the poll, but I'd rather here your written opinions!
You seem to be missing the Lasts a Full Day option...
Could people post whether their usage is using push or not? Been hearing some heavily varying battery life from people and personally I need this phone to last a full day on push.
My finding so far....
It doesn't last a day doing what i want it to. But I do a lot with it, bluetooth music for hours, wifi when at home, games at breaks, facebook checking, marketplace scanning, phone calls, plenty of texts and email (set to 30 min)
To be honest it does very well, would be handy to get some app that shows % of batt and estimated time remaining.
It does seem to take quite a while to charge from nearly flat, the Omnia 7 has a decent sized battery. In order to increase the battery life i've set the tiles to red, I seem to remember reading a while back that the power consumption is reduced when displaying red for some reason or another. Will keep you posted if i notice a measurable difference to life.
I tend to charge the phone overnight, and by 5/6pm the battery icon is pretty much empty and i give it a boost for an hour to see me through the rest of the evening before getting its proper charge at night.
Remember batteries tend to take a few days/weeks to reach there maximum performance.
Sorry for the disjointed post but its whatever comes to mind as i type lol

Well, the "Lasts a day and a half" covers lasting a full day. If your phone barely lasts a full day, then you would pick the first option. If it lasts a full day pretty well, then you would probably have enough juice to go another half day, therefore you would pick the second option.
Thanks for your feedback rlatarche! Yeah it might be true that the battery needs to settle in and be better calibrated, after being drained and recharged. That'd be awesome if your battery life improves sometime!

But what if you have, say 15% left at the end of the day. That's not enough for another half a day, but I wouldn't say it's barely making it a day.
Depends on what you mean by barely.
Of course, I'm only messing with you.

Haha I guess. There's no way to edit polls though, is there? I couldn't find the option to at all :/
I can play music for a couple of hours while commuting, surf occasionally throughout the day over Wifi and still have plenty of charge left by bed(charging)time.
Of course, the joy of not having a sealed phone is that you can always buy a second battery
Battery does not last long at all.
Im a pretty heavy data user. Email, Attachments, Browsing, Wifi, Etc. Fully Charged this morning,its now 3:00PM and it needs a charge. barley see the white battery level on the display.
I have added a 16GB Class 2 Micro SD card. Everything is working fine. I hope this is not a related issue.
Anyone else experiencing this as a heavy user.
Overall im very happy with the phone. very fluid and easy to use. Great one handed operation.

I think the battery needs a few charge cycles to attain its full capacity. Also I think it is suggested that you charge the Li-ion batteries very often first few days and don't let them deplete completely.

Well I ended up getting the HD7. Battery life isn't great over here either. I got through until like 6:00 tonight, from a morning's charge. As the other guy said, the batteries might need some time to train themselves.
The problem with battery usage on the Focus and the Omnia 7 is the S-AMOLED display. AMOLED displays have different power usage depending on what is showing on screen while LCDs tend to have pretty much the same power usage no matter what is showing.
If you're seeing a white screen on your Focus, it's using about 3 times more power than the same screen on an HD7, for example. That means that if you spend most of the time looking at websites, the mail app or the facebook app, your battery will last less than on a phone with an LCD display.
However, if most of the time your phone is on standby or you're using apps with a black background your phone will last a lot longer than the HD7 also thanks to the bigger battery (1500mAh vs 1230mAh).
Last night my Focus received a full charge.
Took the phone off the charger at 7am and needed to put it back on at 7pm.
2 hours of phone calls.
Gmail (Push, 45 emails 1 attachment)
Texting (40 texts)
Light browsing of the web
I have had some accidental camera button smushes and that turns the phone on, and it doesn't go back to sleep, so that could be some drain.
I used it on Nov 8th from desk at work with it plugged in to wall charger. It took nearly the whole 9 hours I was there to charge the battery while I was using it. I was using it VERY heavily. Due to MicroSD issue (Lost everything on power cycle) I had to re add apps over the air. I streamed & downloaded from Zune, had all 'use location' features on, activated find phone fast feature, linked 4 email accounts, I pretty much got paid to play with my phone all day.
Nov 9th, I woke up with full charge around 7am. Didn't use phone much till got to work 9:45am. Today I left it unplugged from wall to test battery life. I streamed from Zune and Last.FM, and had 43 minutes of phone calls, 47 text messages, 11 of which had pics attached, and used map with location and traffic on when I went to lunch. Note the screen is off during music streaming. I also used a very simple $10 Logitech 2 speaker set that plugged into my phone, with phone volume on 20. When I got into my car at 8:15pm I still had life in the phone. I assume that using the external speakers greatly reduced power drain on phone. I have a spare battery and wall charger. The wall charger takes about 5-6 hours to charge a dead battery. I'm not sure yet how long it takes the phone to charge the battery, since I sleep while its doing it.
Mine is almost dead by late afternoon.
I shouldn't have to shut all the extra like wifi, bluetooth, location and dim the screen just to scrape by for barely a day. It's either the OEM batteries, or inefficiencies in the WP7 code. Since no 3rd party apps can run the background, I can't blame them...yet!

[Q] How often do you charge your simple touch

How often do you charge your rooted nook simple touch? after i rooted mine after reading on it for about 6 hours for 2 days, my battery dropped to about 78%. Is this normal or my battery draining too fast? also when nook goes to sleep mode it doesnt drain battery right?
It kinda depends on if I'm using it a lot during school. If I have the WiFi enabled and I'm taking notes with a lot of screen refreshes, then it ends up at about 50-70% battery at the end of the day, at which point I either charge it that night or the next. Other times when I don't use it for much other than writing down homework, it doesn't go down too much. I haven't charged mine for a few days and it's at 40% right now.
I don't charge mine all that often depends on just what I'm doing with it. If it's got wifi on it's a couple of days, if I'm just reading or not using it it's a lot longer. I intend to eventually do a battery test of not using it, using it without wifi, and using with wifi, but it could be months before it gets finished (or started) since I don't have multiple nooks. lol
I've only done testing for 10 hour stints, but here's what I've noticed:
With wifi off and the unit mostly sleeping, it uses about 0.14% battery per hour.
With wifi on and the unit mostly sleeping, it uses about 0.9% battery per hour.
With the wifi on and using the unit furiously, it uses about 8% battery per hour.
I haven't had the unit long enough to develop any "typical" daily patterns yet. I did set up Tasker to only turn on wifi when select apps are run, and shut it back off when they close. This seems to give me the best of both worlds.
So to answer the question, I charge it when it gets low (< 30%). How long that takes varies based on usage.
It seems you all are lucky. I am using my nook the same way as bobstro, and I have had my nook for 3 days. I charged it completely. After reading for 4 hours max, and playing with android for 1 hour, I am at 30 - 40%. What is going on?

Make sure your wifi isn't needlessly running say when you're reading.

A lot depends on how many screen refreshes you're doing, and network/wifi usage. If you're rebooting a lot, and raiding the Market, it will go more quickly.
Try just letting it sit unmolested for a bit and see if it levels out. With wifi off, mine is barely sipping power when in standby.
You also could be seeing bogus calibration. It's not dead until it's dead, regardless of what the gauge says. I've had Android devices blasting audio for 3 hours when the gauge read 1%. I'd give it a few more days and charge cycles before worrying too much. I think many of us panic when our battery doesn't last long the first few days, forgetting that we're playing with it constantly.
Of course, if you're still seeing poor battery life after a few days, definitely take it in for an exchange!
Ok. I charged it to 100% last night and then turned it off when it completed. This morning, I turned it on, and it has been on for a total of 4 hours. 2 of these hours were in standby, a half was reading, and the rest were taking notes and chatting with friends. Two hours were spent with the wifi on and two were spent with the wifi off. It is at 90% now. I think the part about misreading the level is what happened to me.
On a related note, anyone know of a good battery monitor widget for ADW?

When I'm in compulsive battery tracking mode, I use Battery Monitor Widget Pro ($) for the graphing features. It allows me to go back and compare a week's worth of battery performance data. I also get a good feeling when I glance at it and battery availability has been flat for an extended period.
There's a free version, but I don't recall how useful it was.
Once I'm comfortable with things, I plan on removing it and any other monitoring tools, as they do consume some battery themselves.
Thanks. Will have to check that out.

Battery life.......Does it really matter?...uhhh NO!

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.

And there is your only problem.........it's not "airplane" mode while you sleep. You could charge while you sleep. Again problem solved.

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.
