How's the battery life?

Sounds like Sprint got the chavvy notes. My phone from US Cellular doesnt turn on the screen when it receives a text, just a LED flash.
Regardless i suggest using the messaging app SMS Go Pro. Its free, it allows you to make it so the screen doesnt turn on, you can change the color of your LED, the rate that the LED blinks at, you can actually send and receive messages in a group, even with iphones, you get to keep your usual input method (samsung keyboard for me because of the spen/voice/swype in one), it just works way better than the stock texting app. I dont even like replacing stock features with third party versions because you always have to sacrifice something important, but not with this SMS Go Pro. No sacrifices, just benefits. Well I guess the app icon looks kinda stupid so you have to put a silly looking icon instead of an envelope on your home screen.

Sorry, you're a little late to the party. Already found a solution with SMS Pop Up app. Does the job. I had lots of issues using Go SMS on my Photon (became extremely laggy), so I decided to stick with stock this time around.

For the love of god. Ok, so my previous findings on this thread were with me having brightness at 40% the whole time. So today I did 90% just to see.

I need to go to bed. It's still at 28%, and I have 17h 41m on battery, 5hr screen usage. I'm on part to hit 7.5 hours screen time, and I've had the brightness cranked today!

How is it actually doing better? I don't even understand.. But I know I LOVE the battery life of this phone. For once I don't have to charge it at work, or on the drive home, or at night watching tv. In fact, I've had it a week and the lowest it's been come sleepy time for Phases - 25%.

Now, I did noticed a few minutes ago while trying to figure out a drop in quadrant score, I did have all 'power saving' options enabled today. I'm not sure when that happened but - the only lag I see from that at all is in the notes app. I don't notice a change in the web/brightness options.

Shrug. I can't complain at all. Maybe I've always just had bad luck with phones, but this stomps the extended batteries I had on my X and Gnexus, and with so much more real estate - I just find that fantastic.

Sorry for those who are diappointed! :(

Maybe tomorrow I'll try with Skype on all day long too. That's been a battery hog for me in the past.

Edit: I ended up watching 45 minutes no netflix to drain more. 18% left, 6hr screen time. Went to bed.

Now I'm extremely jealous! :p I've turned on all of my power saving options just to see if I can get close to what you're experiencing.

One thing I've noticed about this phone is that the battery meter seems to decrease very quickly between 100% and 90%, and then seems to last quite a long time between 70% and 50%. With my iphone it was probably the opposite - it would stay at 100% for a long time, would slowly decrease to 90% and would then speed up after that. Strange how these things work.

As an experiment I turned off bluetooth in my car this morning to see whether this was causing the battery drain during my drive, or whether it was due to driving through coverage deadspots. With the bluetooth off I arrived at work with the battery at 99%, as opposed to the usual 95%. In this time I also received a text. It seems that some of the drain might be driving through deadspots, but the vast majority is the bluetooth connection keeping the phone constantly awake.

Is there any way of getting the phone to sleep while still maintaining a bluetooth connection? On the iphone the battery would only drain if making or receiving a call through bluetooth, otherwise it seemed to be asleep and the battery was unaffected. The battery decreases on this phone regardless of whether the bluetooth is being used. Would be great to find a solution to this.
 
@asdfasd My phone has been on battery just a little over 4 hrs with BT & GPS on the entire time. You'll see mine was in deep sleep 2.5 hrs so although BT & GPS were on, they weren't keeping the phone awake. I really think yours is draining dut to the dead spots you mentioned.

To be honest I don't even know if there are deadspots during the drive - it's just a possibility that was brought up. When I've checked the phone during the drive it's had 4G connection.

The car does give the ability to play music from the phone via bluetooth. If I even briefly selected this option with the iphone connected it would run itunes in the background and would drain the battery. By making sure I didn't select this option on the car, I ensured that the battery didn't get drained due to this.

I'm wondering if the car is activating something similar in this phone, but without having to actually select the option on the car. I looked through task manager on the phone and couldn't find any music apps etc running, so it's a bit strange. The difference in battery when I have bluetooth connected vs unconnected convinces me that it's related to bluetooth.

I also looked on GSam Battery monitor - and it specifically said that the bluetooth was keeping the phone awake during the drive.
 
I hope you find the culprit.
I know on my phone BTand GPS definitely didn't play in the background keeping the phone awake as indicated by my deep sleep time.

Also, you mentioned playing music during your drive. By any chance did you notice how much battery "media" was using?
 
Well, I'd say the Anker batteries work as well as the OEM ones:

The only downside of the Anker system is that the charger takes forever to charge. I mean, hours upon hours upon hours. I'm curious how long the Samsung charger takes.

Thanks for the screenie. What mAh battery were you using? And what was your screen on time and we're you on wife the whole day?

Thanks!
 
With everything on (wifi, gps, bluetooth, auto brightness, etc., and nothing in power saving) and starting with 94% battery - drove today for an hour using GPS and even made a short call. When I got to work, it was down to only 80% which unbelievable for me coming off DX. This is a best benchmark for me ;)

LTE doesn't impact this battery as significantly as other phones I've had - I turned off WiFi so that the phone could only use the cellular signal (especially since it's weak in my office) to see how long the battery would last.

Easily got 14 hours on pure LTE before hitting the 40% threshold with moderate usage (i.e., all toggles on, some web surfing, streaming, texts/emails).

This battery is no joke!
 
I am a moderate user, but when at work i have really bad signal switches from 4g to 3g often and it usually is a weak signal and no wifi available. i have gone almost 20 hrs and had about 40% left on it.
 
Today has been amazing. It's my first day with the Note2 (how are we referring to this anyway - n2, nII, note2, note II?). My android "history" started out with an HTC Incredible (original) and then I moved on to a Galaxy Nexus - both had horrendous battery life. I bought extended batteries for both but it still sucked.

My loving fiance got me the note 2 as an early Christmas gift and let me open and use it early since it arrived last night.

I purposely left the phone unplugged all day after having a full charge overnight. As any first day with a new gadget, I haven't been able to put it down. The phone's been on battery for over 7 hours now. Screen on time is at 52% and the battery is still > 60%. I'm blown away! This also includes an hour lunch walk using Google Tracks to track my walk, a handful of pictures, constant music playing, and surfing Reddit.

I'm simply blown away by the battery life. I hope it only gets better from here! :smokingsomb:

Still the same Anker battery, just now:

It's a 3100 mAh battery, but like OEM. Screen on time for this was 1h 16m 32s with auto brightness on. I've been on wifi 20h 8m 12s.

I did a test in this thread a few days back where I only used 3G and LTE and still got 18+ hours out of the phone. That was on the OEM battery.

Over 24hrs of battery with a little over 1hr screen on time? That's barely using your phone at all.

This pic is from a few days ago. Notice the screen on time. THAT'S using a phone. :D

I'm amazed how the battery has been so far. I upgraded from a Galaxy S2, which I usually had to charge roughly once a day. The Note 2 lasts several days with the same amount of use (web browsing, some youtube, lots of email+texts, minimal calls). Charged from 25% to 100% in a little over an hour the other day which surprised me. Hope the battery continues to last this long.
 
@hobo That's another thing I like a lot- How fast the battery charges. Although I have to admit my E4GT was no slouch in the charging department either. With the Note 2 I've unplugged all the chargers I had all over the house and put them away somewhere.

Ok, I've seen where you had your screen way down, then posted a lot of these. VERY VALID!

I'm interested in auto in the outdoors all the time. Will we see the 5-9 Hour screen times during almost huge% screen on time? Well more more like 70% on time with heavy chrome use that's interactive....

Oh, and bright sunlight... ugh I'm stretching this thread.. probably need to shade a little which isn't bad!

Thanks!

I don't know if this will help but I read somewhere that "if"our note 2's are not off after the battery has just been fully charged we will notice fast depletion from 100-90 cause it apparently does not fully charge with the phone on. Leave the phone off when charging and for about an hour of green led time and we should get good 100-90 time. Or get the external charger for the battery and swap them out when it's time.
 
This was the same case as with the HTC Evo 4G. From what I recalled it might be because the phone stops charging when it reaches 100% and starts recharging when it reaches 90%. Not sure if this is a fact but it could be the same thing with Samsung.
