    Agreed. Never mess with forcing any type of battery stats or calibration in the two plus years I've been using Android.

    Thank you and I mean nothing but true respect.....with that said, I am completely baffled by this as the battery on this phone is supposed to be out standing! I do realize that this phone has a BIG screen and it is packed with a lot of Power and requires a lot of power, but......isn't something like email one of the main purposes of a smartphone? Although this battery is lasting a bit longer than my Thunderbolt, but really not by much! Yes, I know there is NO comparison between the Note 2 and the Tbolt.....I guess I expected so much more from the Note 2 battery based on what I have read. I did set Gmail and my Cox mail to manual, so they sync now only when I open the app, which seems to me will take the same power if when I open it, it has to bring in 50 emails in one shot, maybe I'm wrong??

    I had Gmail and Cox mail coming into my Thunderbolt with no problems, and didn't have to set them to manual sync. The Cox email I set up on the Note 2 is even hard to look at, as the screen is very dim just when having that email app open on screen....Gmail is much more visible and brighter. I am not a Power User by any means....I basically do email, text, Android Central, a little Facebook and a little words with friends and Occasionally look at You tube videos I rarely search the web, don't watch movies etc.

    I have read so many threads on what to do and not do on this phone......turn down brightness, do manual on email accounts, Turn Off location, s features, any type of syncing....etc. etc. I would think if the phone was built with all these awesome features, we should be able to use them??? I never had to turn off any of those similar items on my Tbolt and would pretty much get through the day with the battery.

    This is similar to what I am experiencing, accept I seem to lose the first 50% of my battery very quickly....this morning, I went from 100% at 7:00 am to 64% before it was even 11:00 am and that was only looking at email, and Android Central and 2 minutes on Facebook. Like you said,The second 50% of the battery seems to last longer....but I am still worried about getting through One day compared to hear people say they could go 2 full days without a charge.....I don't get it.

    No way you can get close to 48 hrs with the 3200mah stock battery, unless you have real minimal use

    I had mine fully charged Friday and 5pm and didn't plug it in until this morning (Monday) at about 10:30 am with 9% left. Obviously not heavy use but it was at least moderate. I used it when I wanted to and I'm thrilled with that. Way better than my Thunderbolt with the stock battery. I'd get one day out of it, almost 2 if I didn't use it at all.

    I hope the people who are having battery issues get it straightened out. I just went almost 48hrs before charging with 6 plus hours of on screen time. I'll let you know I have location access turned off. Facebook sync is turned off also. Facebook is another huge battery snob. I'm more then willing to list all my settings if it can help one person.

    are you shutting off data and wifi when you are not using it? are you set to LTE/CDMA in settings>more settings>mobile networks>network mode?
    During those hours of major power loss are you in a building with poor reception? are you using any task killers besides the stock task manager?
    If i've made life easier buy me a Macchiato

    I would also add that you should turn off auto-synching of accounts and GPS when you're not planning to use it.

    Thank you so much for the help! Ok hmmm, just checked on the network setting and it was on "Global" geesh, I think I know/assumed it should be CDMA, Best Buy doesn't really check those things when they set you up I guess.

    Will that make a big difference? What exactly does Global do? I have been going through and turning off auto syncs and other items today. Also, I have great signal and 4g pretty much everywhere. I do not use a task killer. I learned not to do that on my prior Thunderbolt!

    Can you post all of your settings. I have a SGH1317 att GN2. Before the 4.1.2 upgrade I had fabulous battery usage. Almost too good to believe. Nothing was disabled, wifi was on. After the update there was a remarkable change. I now have all att bloatware disabled other than hot spots. Im thinking of disabling music media and mobile media. What about location services. This is a royal pain in the ****...what did the update do?

    I have WiFi, bluetooth, GPS, sync which is off unless I need to use any of it. My brightness is at 50% with auto off. I have 1 email account with push as well as my gmail and the other set to sync every hour. I have everything that deals with location off. Facebook and Twitter sync is disabled.

    When I'm on lunch today I will list everything I have checked along with my battery life today. I can tell you right now I'm at 35percent left with 22hrs of on time. 5hrs 41mins of on screen time. Also I have had no signal for 3 percent of the time. In my book almost 6 hrs of screen time with 35 percent battery life is great.

    Unless something else is going on I can say signal strength can be a significant difference. I live in an area with crappy cell service for any carrier (I have Verizon and have had others in the past), there are times I drop off the 3G radar, forget LTE (but 1/2 mile away - *uphill* - is 5 bars) and if I spend the exact same day at home vs at the office (5 bars at the office) then my battery will drain much faster at home than work. I can't tell you definitively how much but probably in the 30% different range and maybe more. Both have WiFi so that's constant between locations.

    Aside from that I'm at 90% after 6.5 hours of light use, one short call, some emails and texts, and 50% of the drain is screen right now. Yeah, can't stop playing with the damn thing. If I was home I would expect to be down in the mid 80s or low 80s by now, just due to reduced signal strength on cell radio.

    If you find that draining it once a month and recharging it works best for you then by all means continue to do so. However, per information on Lithium ion (Li) batteries at the Apple website (this is about the Li batteries not their use specifically in Apple products) you should let your Li battery go through one "charging cycle" once a month which is not quite the same as draining your battery once a month. Although completely draining and recharging takes your battery through a charging cycle, your battery can go through a charging cycle in a month without fully draining the battery.

    A "charging cycle" is where the battery has lost 100% of its energy and been recharged, but the 100% loss may occur across multiple recharges. For instance if day 1 you use 33.3% of your battery then recharge it fully overnight, then day 2 use 33.3% of the battery then recharge it fully overnight, and then day 3 use 33.3% of the battery and then recharge it fully overnight, on the morning of day 4 the battery has gone through one "charging cycle".

    You actually might not be doing anything wrong. The greatest improvement in battery from the Thunderbolt to the Note 2 is idle usage (plus sheer size). On a Rezound battery, the Thunderbolt will drain about 4-5%/hour on wifi and about 10%/hour on LTE with the screen off. The Note 2 will drain about 0.5%/hour on LTE with the screen off.

    However, if you are using the Note (which really just means having the screen on, since the processor is fast enough to not run down that much, in general), then I generally expect the battery to go down by 12% for every hour of screen time. So if I used the phone for all 4 hours, 11 minutes, I would expect the phone to be down to 48%. Where the Note 2 is great is that usually, you wouldn't be on the phone for 8 hours in a row. So a couple of hours in the morning, a couple of hours in the afternoon, and the phone would still be at about 40% at night. If the phone doesn't charge overnight, it will still be at about 35% the next morning. By contrast, with the same usage, the Thunderbolt should be completely dead by 4 or 5 in the afternoon, and if charged up to 100% again and unplugged (and LTE is left on overnight), it would be dead again before morning.

    The battery meter is also amazingly accurate -- if I reboot the Thunderbolt, the battery meter might show 60% before the reboot and 35% after the reboot (no, the reboot doesn't take 25% of battery!). So when the Thunderbolt battery meter shows 40% (nominal), it's really more like 15% (actual), and it plunges from 15% (nominal) to 0% in minutes. With the Note, a reboot usually doesn't change the battery meter at all, or maybe by 1% or 2%. So 40% battery showing on the Note usually means that there are still 3 hours of screen-on time left. So the Thunderbolt is really, really deceptive that way.

    In the other post where your battery was at 91% after 52 minutes, and screen was at 60%, that is consistent with having the screen turned on during the whole time (based on my 12%/hour usage estimate, I would expect it to have used 10.5% or so by that point).

    Hope this helps.

    Also, I don't use the phone as a telephone much, so I don't have an accurate estimate of how much battery use as a telephone is, but it is also not low. I currently have 67% left, which GSAM estimates gives me 10 hours of talk time, so if that is accurate, then 1 hour of phone usage also equals 6.7% of battery. I currently have screen on time of 2 hours, 8 hours of time off the charger, and 10 minutes of talk time (so my estimate of use would be 24% + 4% + 1%, or 29% vs. 33% actual; I am having issues lately with something as well, perhaps Adobe Reader, because battery use typically used to fall *below* the estimate).
