[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] metus666:
I've found the reason why I was having bad battery performance on my GSN.

I used the MicroSD from my SGS directly into my SGN, forgot to format it. Now that I've formatted it I've also completely charged my phone while it was turned off and after it reached 100% I unplugged it immediately from the charger. Then I went into CWM and reset the battery stats.

Now I've been using my phone for 9 hours and it's still at 85%!

Any ideas what's eating this 40%?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] wonderwout:
We can only guess, likely some app/service is preventing your phone from deep sleep when screen is off. Tab the graph in that view and check wake timeline and screen on timeline if they don't match find the thing keeping your phone awake and fix it.

Edit: Then again, if your phone does nothing Android OS will be high, this is a much discussed item and considered a bug but doesn't mean a drain necessarily. So there is maybe nothing to worry, doesn't hurt to check for wake locks though.

Same for me, something is doing a massi?e power drain, even when not in use.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] henklbr:
I don't know what did the job, but after a few suggestions overhere (un-install Skype, install Green Power Premium), my battery drain overnight went from about 30% to 6%! (100% at 2200, 94% at 0700).

When I went to settings, battery usage, I saw also that usage by Android went from approx 80% to 40%.

Now at 40%, "other programs" that are using the battery power are also shown (this wasn't the case when it was at 80%!) . . .

I'm a happy user now, and for all the writers overhere in this thread: thanks for your suggestions! :)

The same as mine.

Android OS takes the lion's share of batery usage.

Optimizing is necesary!!!!
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Diewi:
I've stripped the problem down to the wlan component. I don't know if this massive battery drain is caused by the driver or a wlan service. Anyway, as long as wlan is active, the cpu doesn't go into deep sleep mode. I'm currently trying to figure out the root of the problem. It seems I get closer. Let's hope the best.

Dunno what they are on about with the web browser thing... opera mobile is HW accelerated and I don't even come close to under 4 hours of browser time.

Hell, my girlfriend played games on this thing for 3 hours straight this past weekend and it went from 85 to 50% in that time, gaming is way more intense than web browsing especially cordy.

I honestly dont know how close or far, but incrementally I can tell you that there is no way that if I browse for an hour my battery will go from 100% to 25% I will try this tomorrow morning and report back.

Yes that would be nice.

Or is it the Flash thing which is eating away the battery?

May be you should leave the Flash Player on-demand while testing.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] NZtechfreak:
I'll be doing a browser test too, would be surprised if it came up as short as GSMarena's test.

Their video result was similar to my own, only I was playing a 1080p MKV, not an SD Xvid like they were (and frustratingly they don't give any information on what connectivity is enabled in the background/brightness settings etc, quite useless). I turned background stuff off and had brightness at 50% (much brighter than you need indoors to be honest), and had the speaker volume set to full - I got 8hrs 16mins.

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] aussiebum:
There's not enough detail in the test methodology on the web browsing aspect of GSMArena's battery tests. All we know is that they use wifi, so any testing imo is going to be very variable and subjective.

Some of the things I've asked them in Comments:

* What website is used for the web browsing test?

* Is it continous data transfer or do they wait until the page is fully loaded and data is idle before hitting refresh?

* Screen brightness level during test?

* Flash enabled/disabled?

* Is the phone wiped and rebooted to ensure no other apps interfere with the test?

* Distance from router / wifi signal strength?

* Wifi connection type?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] NZtechfreak:
Agreed, not enough detail for either of the non-call tests. Funny that their goal was to 'revolutionise' battery reporting in reviews, but their 'revolution' is rather useless itself.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] rossygnol:
Well said, all Samsung 's smartphones are much brighter the the iPhone, so if they don't make the test with level brightness n flash disabled for the Samsung, then this test is rubish...
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ChodTheWacko:
it's semi plausible. Wifi on my note bleeds battery while I'm browsing. I haven't seen a fix for this.

Also many web backgrounds are white and that's a worst case scenario for amoled battery drain. Add on a HD large screen and you do the math. I changed opera to monochrome I e. green text on black and that has done wonders.

- Frank
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ph00ny:
I guess some of you guys have never owned an amoled based phone

web browsing with white color will eat through the battery like there is no tomorrow because of the power draw from the screen
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] watch_mania:
Screen is a bit (just a bit) warm after use. Definitely not cold. 20% brightness, running on 22 degrees environment.

Let's do a stupid math on comparing the inefficiency of the screen. Say that an amoled pixel had i inefficiency in which it gets converted to heat, that means Galaxy SII would have i x 800 x 480 = 384,000i. For Note that would be translated as i x 1280 x 800 = 1,024,000i. That's 2,6i more than SGS II.

..err let's forget about it, not really sure what the calculation would means :p Could be useful for battery life/performance with comparison to SGS II, but it would be a bit complex to calculate I think :p

I think for the screen size, a well-built LCD should draw much less power than AMOLED. But then, seems that LCD construction requires more thickness compared to AMOLED, not to mention bigger bezels -- probably for putting in the backlights. So, without redesign of the Note's internals, if an S-LCD version of Note ever comes, it won't be as thin as the AMOLED version.

Hence I bought a Galaxy Note :D

I'm using my Note for 4 days, my battery life (from full charge untill phone turns off) is about 10h (+/- 1h).

Usage:

HDPA+/3G, GPS, ACTIVE SYNC (Google, Twitter, Facebook, Samsung, WhatsUp) - always ON, 1h music, 0.5h games, 1h web browsing, screen 10% brightness, 0,5h drawing, 1h apps/market/files, 40min calls, 15 emails, 10 sms, 10min skype front cam, 10 photos, 1 video (5min). 3h of the time phone is on WiFi

Looking good sofar

Got my Note yesterday.

Been using it pretty heavily for the past 4,5 hours off its first full charge.

1 hour on WiFi. The rest on HSDPA. Lots of synching, still setting the thing up.

(Off topic: Touchwiz is nice, but switched to ADW pretty quickly. Everything shows up so big. Such a waste of the huge screen estate on the Note).

Battery still at 67%. Expect it will improve over the coming couple of charging cycles, but already is promissing better battery life than my beloved Desire.

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Super Chimp:
I think whatever you try there is always going to be an issue with battery life when on the net on it, just because its screen is so big & that inspite of the claims Super AMOLED isn't that battery saving. I have turned off the auto adjust brightness as it made the screen too dull but I still have it below 50%. Also have a very screen out interval.

Tip for everyone:

If in the battery chart you see the phone is 'Awake' even though the screen is off, you can probably find that application by checking wakelocks via Betterbatterystats or something.

Hi, got my Note yesterday. So it's the first charge that I'm using. As you can see in the picture attached overall you can use the phone (display ON) whether it's browsing, playing games or watching videos it doesn't really matter. They all consume the battery overall the same.

So as you can see, you can use your phone intensively for 7h1/2. Not bad at all. The brightness on my phone is about 15% which is really enough, even outside.

I love the battery life of the Galaxy Note compared to my Galaxy S2, I'm not a heavy user, just the occasional Gmail, Internet, and Texting.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] GALAXYNOTE:
I find that it really depends on the task and judging by the screen on time alone can be kindda misleading. For instance I can have over 9.5 hrs of video playback on my device with volume on full (tested it myself). This was mainly due to the fact that movies are mostly 1.85:1 and it leaves two black stripes at the top and the bottom of the screen so effectively only 2/3 of the screen is used. While browsing on dolphin HD it can drain my battery from 100-0 in 4-5 hrs

Other than that I also find dolphin HD drains my battery twice as fast as Opera mini. Now I try to avoid full feature browsers and stick to the mini-versions. Oh, and avoid crayon physics if you want more than 4 hrs of batter life.

With regards to battery life I will need to mess about with my Galaxy Note a little longer, only had it for about 5 days and charged it twice...

- Around 30-40 mins wifi/internet browsing

- Around 10-15 mins of video

- 30 mins of voice calls

- 10 sms messages received & a further 10 sent

- Bluetooth transfers - Around 5 mins

- General playing with the phone/screen/gallery - 15 mins

battery acting in reverse????

on the first day i didnt put it on charging just waited for it to get drained out to 0% but when the battery was at 10% it was time to sleep for me...so just kept it aside and slept off and when i woke up after and hour to just check my note i saw battery went up to 11% then again after half an hour it went upto 12%...so i thought of checking it again half an hour later then i could see battery at 10% and finally i decided not check further n slept again...by morning it was 6%.

ANYONE HERE WHO WENT THROUGH OR NOTICED A SIMILAR THING?

anyhow i put it 4charging the next day when it went to 1% after say for 5hrs of charging it didnt show 100% it only showed 99% so i just removed the charging plug-in...havent noticed the % going up again though....

i have been using e.t.a for my battery % on my s2 which worked fine and im using it on my note...can it be blamed for this? or it has got something to do with battery itself? or it was my fault that i waited for it to drop the % till 1% ?

Install Current Widget from the market, enable logging and wait. For comparison, my DHD uses around 3-4 mA in standby.

One thing though, if you have a lot of apps and widgets that auto updates, the device will wake up more often and use battery power, so think twice when you set the weather to update every 15 minutes. Once per hour is more than enough. It's the same with RSS and stuff like that.
