Hello, I new in Note and I just did battery calibration with battery calibration app. I was playing GTA VC about 50minutes and get about 40percent battery drop. Im with Slim Bean latest ROM and hydracore latest kernel , on lowest brightness and on 1ghz CPU speed. But I think is battery drain, how think you?
looks like screen was on for around 2 hrs and it dropped from 100 to 40 %.. looks ok to me though

So I can use my Note just for 4hours with screen on? Its not very long :/
Yes. Seems that's the full screen on time

No, you can extend screen on time by doing nothing on the phone. But you have to make it so the screen wont turn off after X amount of seconds/minutes..
well you can switch of mobile network and wifi, screen brightness, that will give you more. But generally no. The battery is small compared to fullscale tablets, but they dont pack a mobile network that uses a lot of energy.
Im always switched off mobile data, use lowest screen brightness, sometimes little check up emails with wifi, play little games and it last about 4 hours screen time on.
50mins playing VC and 40% battery drop...? No need to worry it's rather normal
I just asking because I new in high screens phones and now I understand that it takes alot of battery power for screen like this
I walso want to ask is it normal that when I charging my note with original wall charger, phone in charging mode is automaticaly little warmer, like 2-5 C more like not charging. and also games feels little laggy when charging and also for example when I play order and chaos with mobile data on not charging phone it gets ~45C warm but when charging it become 59-60 C hot Is it bad? does it gonna fry little bit?
lol what kernrl are your running
Play airport city game for 1hour and u will get 65 percent battery drop.... With a temperature 65'C and then connect your charger... It will say unable to charge due to high temperature....

I mean really hot! Normal usage is ok but when I play games or use web browser for half an hour, it turns hot (back and front, lower body). Does anyone have the same problem?
Another thing is the charging time is too long!
Here are the answers from other forum:
Yes the liquid tends to warm up at the lower back half and once that happens, theres no way you can recharge it till it cools down. Feedback from acer engineers theres a temp sensor right behind the battery and if the temp goes above 40c...it'll stop charging. I think that maybe is one of the reason Acer didnt really launch this model worldwide?

Phones with Snapdragon chips in them get warm. The Desire does it; the Nexus does it. I wouldn't worry. My nexus takes about two hours to charger to full.

I have the same problem, its very hot, im worried for the health of cpu and battery..
At least for the charging troubles, using setcpu I defined to run at 500 (around) MHZ when on charge and no overheating then, plugged from evening till morning or using gps for 2,30 hrs with charge connected. It stills warm but no overheating... Tips from EvIl rom, not mine
The lower part is where the CPU is, battery heat would be from the upper back part. Also computer USB charging is slower than wall socket charging.
ive had a nexus one since the day it came put and since upgrading to froyo and now 2.2.1 my battery lifes been horrible. my normal settings are no wifi or bluetooth on. no sync. im running uv kernels and my battery life is still horrible. i recently sent my nexus to htc thinking it was a hardware problem. the new nexus dies just as fast. ive almost literally looked at every battery life thread and tried tips and still doesnt help. my phone doesnt last 8 hours let alone 24 hours. ive checked my battery use and the only thing over 10 percent is my display which im using auto brightness. any help would be so greatful because ive tried everything i know how to do
Did you replace your battery?
Time to replace your battery!!!

already replaced the battery before i got the new phone.
Dude same here. It's obvious the N1 is lacking in battery technology. What new phones are you considering?
that's definitely a dead battery, I've got my Nexus One since 2nd March and keep using it till now, still there is 92% of usable capacity.
Check the battery cal thread. We just finally hacked the nexus battery EEPROM chip and can tweak voltage etc. The changes got merged this week. So maybe some hope still...
well these things can definitely kill the battery extremely quickly if you use them a lot.
i personally don't have a problem with the battery life on mine on a normal work day because i only use it probably on average 5-10 min an hour for a 9 hour work day and by then i'm usually at 50-65% battery depending on how much i used my phone.
if you suspect that the phone is the problem and not the battery then try downloading currentwidget its a small widget that will tell you exactly how much power your phone is using in miliamps. it takes about 1 min for it to refresh so it does not work in real time but this is kind of nice because it allows you to see how much power its taking (or receiving if its on the charger) when its in idle
mine usually reads 3-5 mA when i unlock it so that is what its taking when its in sleep mode.
the most i've ever seen it take when draining the battery is about 465mA i would say that the average drain when i'm using it for browsing websites and using simple apps with the screen at half brightness is about 350-400ma or so
one thing is for sure though if you use an N1 heavily it can and will kill the battery in a matter of hours, if i play angry birds for example with my screen on half brightness after a few hours i'm at about 20-30% battery easily and the phone itself is very warm from the constant CPU use.
and btw the bad battery life is the combination of the AMOLED that takes massive power compared to an LCD and the 1st gen Snapdragon CPU clocked at 1ghz, battery life without the screen on and with minimal CPU use like streaming music for example or playing music with BT headphones i can go all day easily. it only drains like 5% an hour maybe a tad more but the difference is that the CPU is not working very hard and the screen is off completely.
AMOLED using more than LCD? What did you smoke mate? ^^
AMOLEDs have been made for low power consumption, especially for black colors...no way it uses more battery than my SLCD variant...

they can take less power with the proper screens yes, they are dynamic in their power consumption like plasma's are in that how much power they use is directly related to what they are displaying and what the brightness (or contrast in the case of plasma's) is set at.
LCD's are predictable and constant with their power drain.
AMOLED's are capable of consuming more power than LCD's of the same size if given the right display material (mostly white, mostly brightly lit content)
considering that most of the websites and even some apps i use on my nexus have white backgrounds it explains why my screen pulls so much power when i'm using it

There was a test done somewhere that showed that all the phones with AMOLED variants did the worst in battery life. Best battery? Droid x
true, white on white, amoled does use more battery...but meh...argh it killed my point xD

that sounds jsut like my phone. 5 to 10 minutes of use an hour and im at 60 percent. that cant be normal! angry birds for 10 minutes is like 8 percent battery loss. like i said i got a new battery for my old nexus one then noticed that the "issue" still existed so i got a new nexus one and my phone still dies rapidly. why is it that some nexus ones are better. i hear people say they get excellent battery life and to me on a brand new nexus one with a uv kernel my battery life is still horrible?
It's normal there is nothing wrong with your nexus one they suck battery if you use them heavily

How much is the display uptime on that?
Looks like you might be using a very high brightness level!
Yes tap on the display line to show more details of how many of your 14h the display was on? My guess is 3
Try lowering your screen brightness and using black backgrounds wherever possible. You can't blame such a gorgeous display for using power!
To be fair thats quite an average percentage and whats wrong with 14hrs uptime with around 50% battery left?? And think about it.. the screen is massive what do u think is gonna take up most of your battery?
My brightness setup is 0%. And you can see it's drop a massive amount of juice when the scree is on.

Those are fairly ordinary statistics. I don't see why you should be unhappy at all.
Your display should be at the top. I would worry if it wasn't.
My brightness is approx 30 %. Normally get well over a Day's use....but battery drain always leads with 'display'

Me to. Except on those days when people will not leave me alone. Those days, the Cell Phone usage sits squarely at the top ...
Yep, that looks like fairly standard usage to me.
Looking at my phone now, it is at around 17hrs, with about 3hrs screen on, and 44% left.
I normally get around 5hrs screen on time no matter how I use it. If I really hammer it, with internet, music, games, etc, I can drain the thing in less than 10 hours. If i take it easy, I can get almost 2 days out of it. Either way, I still get about 5 hours of screen on time in total.

5 hours display on time is very good. The best I have EVER gotten is 4, I typically get about 3.5, this is with screen brightness at 10%! How are you getting 5 hours? Custom Kernel or stock? What is your brightness set?

Non rooted stock firmware (LA4 until yesterday, now LB1)
Usually brightness set to 0% (unless i'm outside), Wifi and mobile data off when I'm not using it, ditto bluetooth and GPS.
Doing the same thing with my Dell Streak I used to get about 4 hours, so I'd say the battery life on the note is about 25% better in comparison.
Had my N7 on the charger all day while at work. Got home, unplugged it and fired up Splashtop to stream MLG Summer Arena (flash content) with my desktop. Screen at full brightness, headphones plugged in, and maxed volume. About 2.5 hours streaming and a half our of Dead Trigger, I'm down to 27% battery life.
Feels like the battery performance isnt anywhere near the 8 or 9 hours claimed by Google and Asus. Am I missing something here? Anyone else feel like battery drain is really high? Stock, un-rooted, updated to 4.1.1.
Have a trip in two weeks with a 4.5 hour plane ride and would be nice know my tablet could keep me entertained for the trip...

Even though I don't have mine yet I can say full brightness on screen can effect your battery life. I would suggest looking at what apps are running and possibly what could be eating your battery life.
Full brightness, thats the root cause. Try to reduce to, let say 50% ... Or as lowest as you feel OK.
When I use my gnex at home, I set to 15% ... Thats enough and still very bright.
Outside I use auto ...
Thats why I have a toggle widget for that ...
And I can have my gnex easily run for more than 48 hours stand by woth almost 4 hours screen on time

I dunno, that's weird. I've been playing with this thing all day and have 3 hours screen time and 65% left.. live wallpaper, Dead Trigger an hour, SuperGNES (FF3) two hours, XDA and web browsing. I'm on 50% percent brightness though.

100% brightest is way too bright indoors for me. Optimal indoors for me is about 30% and probably wouldn't go above 50%.
I've been getting 6 and a half hrs screen on time with over a day on battery, this has been 3 separate times. I use this tablet a lot, total time with me adding up that screen on time is over 25hrs maybe 30. I'm not counting the time when I first got it and ran it down several times before I was getting way better screen on time.

I use auto brightness and I'm getting way more than 10 hours use. Thats browsing and the occasional youtube.
Very impressed with the battery life and the whole Nexus experience.
My brightness is to 12%. More than bright enough for me. Getting around 9-10 hours with moderate to heavy usage. Very impressed with battery life.
I get better battery on CyanogenMod then I did on stock. Plus I can underclock to as low as 800mhz and it still runs like a champ.

I have been amazed at how long it last.Over 10 hours with headphones running listening to lots of songs, trying out different apps and then watched the movie.Still never got under the 30% mark on the battery.
I've knocked down the brightness to 50% and will see how well the battery lasts after charging last night. So far I've been off the charger for a little over an hour with 40 minutes of screen time, down to 91‰ battery life.
The stock ROM doesn't have a way to take screen shots, does it?
Seriously, you had brightness and volume at 100% while using Splashtop, then gaming (pretty high intensity stuff) and you're surprised it lasted less than a stated time for Web browsing at like 50% or less brightness?

I want to say the battery tests were performed at similar conditions while watching a movie for the eight to nine hour rating. Perhaps Splashtop pulling so much bandwidth on the network was a factor.
2.5 hours since unplug, 2 hours of screen time, down to 65% battery. YouTube, Chrome, Dead Trigger, and Facebook so far this morning.

Disable Wifi while you're in the air. That should make a difference.
my battery life has been spectacular. one other thing I noticed. when it charges to 100% (my nexus S never did), it stays there until you start using it. Best battery life of any mobile device I have had, ever. Except for my NOkia candy bar phones that stay charged for days.
I think my nexus may be defective. At first I left it at auto brightness, and drained the battery with 4 hours of screen time only web surfing. I've manually set the brightness to 35, and I still only get about 4.5 hours. This is just using Google chrome, no music. Throw in the occasional 10 minutes of world of too. Also what is standby drain for you guys? I lose 14% overnight, about 7 hours.

What screen brightness are you using? Do you close all apps that you aren't currently using? My screen is the biggest battery drain, but I keep the brightness to sub 40. Normally I would just use auto, but I had no luck with it.
When I got the phone, the battery section of settings would estimate 24-26 hours remaining from a full charge. I'm at 90% and it's estimating 15 hours remaining. Anyone else have this dramatic decrease in battery life? My usage of the phone hasn't changed.
The estimated time remaining is an ESTIMATE based on the current usage. (I'm not sure if it's based on the the current usage from a given timespan, since last unplugged in, or what.) The point is that if you leave your phone idle after fully charging, you'll have a higher estimated time remaining. If you use it heavily right after charging, you'll have a lower estimated time remaining.
In other words, it's kind of saying something like "Based on how you've recently been using your phone, you have XX hours remaining." So, change how your using the phone, and the estimate (actually, more of a guesstimate) will change.
Yeah... Makes sense. Phone gets very hot too. Average is 90°...

90F is cool for a phone thats on. your body has an average body temperature of 98.6F. my guess is thst you are giving your battery temp. battery safety is st 60C, which is 140F. your phones cpu has a safety shutdown mechanism that automatically shuts down at 105C, which is 225F.
and battery drain, can be pretty bad depending on the game, is very expected.

What game are you playing? Are you running stock? I would try lean kernel and try to change up the max frequency to see if it helps with the drain while still being able to run your game.
i have wonderful battery life. what ganes do you play, and how bright do you keep your screen usually. i dont play many games, but when i play midern combat 5, it drains battery. but i expect it to, since it heavily uses the cpu and gpu.
