There's an issue with the SGS2 where it seems to never switch down to idle power or the suspend process sucks a load of battery... it's a bug which I think exists in Gingerbread on dual core phones.

I have a sgs2 since May and my battery usage change heavily since.

Plenty things happened, modem bug fixes, custom kernel with optimized compilation, custom ROM too... now, in flight mode, it consumes 0.2%/h, in screen off state with 3G activated, it consumes 0.5%/h and I am investigating more and more governors settings (setcpu) to reduce in game mode ;)

so, you have chance to reduce battery usage with GN if a community occurred around this product.

After receiving the device on friday i spent all weekend trying to figure out what to do with my SGN's battery drain. This morning I left home with wifi off and what happened - the battery now is losing only 2-3% per hour instead of 10-15% with wifi on.

I still don't know why wifi consumes so much energy. My HTC DHD feels much better with wifi than with 3G or edge. Maybe this is the only case of mine but you, guys, could try to manage wifi and see what result will be. Hope it'll help.

Battery drain is 9/10 times an app/service using wake locks inappropriately. In other words not letting your phone sleep when screen is off. There are apps to find these, once found change settings or get rid of them.

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] LiquidNitrogen:
Even though some people are saying they're getting upwards of an entire days worth of battery life, I have put a ZaggSparq 2.0 on order (with a 20% off coupon I found off google, totalled $98 with shipping). Between it and the internal battery I should have 3.4 charges, more than enough to run this thing for a couple days on normal performance and at least an entire day on max performance. I don't intend on having to fiddle around with this thing and change the way I use it just for the battery. :)

After all:

It's got a beautiful screen, why waste it by using dark themes.

It's got a powerful processor, why waste it by underclocking.

It's got tons of connectivity, why waste it by turning it off.

Grab some internal batteries or a Zaggsparq and enjoy its true capabilities. $98 for a battery that will allow you to use your ~$1000 device to its full potential is money well spent, in my opinion; plus it gives you back the time you would have wasted on trying to optimize the heck out of it just to squeeze an extra hour or so out of it. And the Zaggsparq (or other external battery pack) will keep your other devices charged too.

Just my 2cents. :p

EDIT: However, I will be monitoring the power usage on this thing if I get any less than 5 hours on a charge on max settings, considering how some have said certain apps will eat battery life like a fat kid at dunkin' donuts.

Dumb question, how are you turning that off? YOu mean the orientation sensor?

---------- Post added at 01:06 AM ---------- Previous post was at 12:57 AM ----------

To each their own - I am pretty extreme when it comes to turning stuff off when I'm not using it.

If I'm not using something anytime soon, I turn it off because the only thing leaving it on will do is drain the battery faster. Widgets make this pretty trivial.

I think the most important thing in terms of battery analysis is having an understanding of what uses how much battery. If turning that on is worth it to you, then fine - turn it on!

Wifi doesn't sleep

I use Juice Defender. Wifi should switch off after a minute in standby.

Sometimes it does, sometimes it does not. So the battery goes down.

Is there any possibility to find out why Wifi does not go to sleep?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Bigmille:
WIFI sleep works fine with Juice Defender (Ultmiate) on my Note. You can auto switch WIFI off when the screen is off by going to Settings --> Wireless & Network --> WIFI settings and press the menu bottom, there is a otipion call Advanced which offer few different WIFI sleep options.

Thanks I also use Juice Defender Ultimate, but as sad above: Sometimes Wifi is turned off automatically, sometimes it isn't, stays on in standby.

I am finally getting more respectable battery life on my Note. I have went from an overnight (8hrs), screen off, battery drain of ~23%, to ~3%.

Have to give credit to the BetterBatteryStats app for helping me find what has been keeping my Note awake, even when the screen is off. I have improved my battery life by changing the following DEFAULT settings. None of these require root, hope to see even more improvement after I root the phone.

Settings..

Display...

-Turn off automatic brightness

-Turn off touch key light duration

Location and security...

-Timeout to 5 seconds

Applications...Samsung Apps.

-Turn off notification

Accounts and Sync...

-Turn off all Gmail sync (use default mail to sync Gmail).

-Turn off EVERYTHING and sign out

Voice talk

-Turn off EVERYTHING. Especially "Wake up command"

I am using jd plus and I am verry happy with it. It's still learning when and if to switch wifi on or off, but its getting there.

And it gives me the "juice" I need.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] npras42:
Had mine since Friday. Got very poor battery life over the weekend (about 24 hours) when i was glued to it and still learning how things worked (just moved to Android from iOS!).

However, got the hang of things and have turned off a lot of location and notifications for apps that I dont want to use or need. I still have accuweather, facebook widgets and location based services turned on. I also have notifications for email and GMail.

To help save battery, I have the home screen widget that lets you turn screen brightness down with a single touch and turn off wifi/BT quickly. By default I leave WiFi off and have brightness at the minimum setting - only turning up when I use Opera, Navigation or video files. For calls and sms reading/sending I leave on minimum.

Seems to be working very, very well now. Battery Solo Widget says I have 43% battery remaining after 1 day and 10 hours charge. I have not made many calls in that time (5 mins) but have sent 50+ sms messages, browsed the web for a good hour plus just fiddled around playing with settings etc. Excellent prognosis for battery life so far.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] tdodd:
Mine arrived on Monday and I charged it fully before even turning it on for the first time. Then I kept it on charge while I configured it and messed about. I haven't taken any special steps to save the battery other than to have mobile data disabled (haven't needed it yet) and to have WiFi turn off when the screen goes off. I've been using it a fair bit just messing around and have used sat nav with GPS on for about an hour. The screen is clearly the big power hog so that seems to be the area where savings could be most significant if you back off on the brightness a little.

Anyway, It's been 1 day and 18 hours since it came off the charger and I'm down to 1% battery remaining. I shall let it drop to 0 to facilitate battery calibration. I'm not unhappy with the battery performance based on the experience so far. I think that in my more conventional usage pattern, once the novelty wears off, this thing should be capable of lasting me three days without sacrificing any of its talents. In practice, given a phone with no charge is as useful as a chocolate teapot I shall probably end up charging it every couple of days. Quite honestly, if it needs more than that it really will be no hardship to charge it daily, but I can't see it coming to that as a necessity, only if I feel like it.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] theloginwithnoname:
That is *much* better than I would expect.

Does anyone here know of any comprehensive battery tests that was done on the Galaxy Note?

Engadget claims that it can get 9 hours of battery life from looping a video. Has anyone here been able to do something like that?

I'm interested in this phone, but battery life on Android devices have always been bad at least compared to iOS. Yes, I know there are many reasons why Android may have less battery life, but I'm a heavy phone user and even my iPhone 4 doesn't last an entire day without a battery case.

I have 3 push e-mail accounts, browse the web, have Meebo or some other instant messaging app running in the background.

Does someone have a similar setup to mine and can tell me if the battery will last an entire day or not? I don't care about light usage as I rely heavily on my phone for the entire day. I also don't care so much about wifi performance. Since I'm out all day, I rely on my 3G connection a lot. If the phone doesn't last an entire day then it's worthless to me. It'll be interesting if the phone can last an entire day.

I think we need to establish some sort of standards and then test how long the battery life will be under those conditions.

I can get about 8 hours of screen time on wifi-only... (no sim card in it) that's pretty awesome in my book. I'll using very low screen brightness and a lot of apps I use are light-on-dark, which helps a lot. Plus I uninstalled the bloat with Titanium Backup.

It really makes sure that the wifi switches off when the screen is off. You can set it to switch off immediately or after 5s or a minute.

i really recommend trying it if you are losing alot of power in sleep mode.

Also i think you must make sure in wifi settings/advanced that you have the sleep policy to turn off when the screen is off as i am not sure whether green power over rides this setting.
