When did your battery life start to get better?

I have had the phone for 5 days and with fairly light usage, I am still not getting good battery life. I turn off all data and wifi when not using it and screen on time is below 2 hours.
Below is a screenshot of my battery life.

It doesn't get better...get used to it until its fixed in an update , along with the other big issues.

By about the 3rd day it seemed better. But it's also difficult to gauge because the first few days you're bound to toy with it constantly.
Until there is an empirical way to gauge usage, like an amp meter attached to the phone - it's all perception imo.

In the top left you have three things running in the background, im assuming constantly. Uninstall them, especially the battery percentage since you can look that up easily on your phone

Do yourself a favor and try aokp milestone 1 from rootzwiki , and also download lean kernel 1.1.1 on xda. Use interactiveX governor for kernel. This is the exact setup I am using now, and have been for a few days and have been getting insane battery life. Hope everything works for you.

Last time I checked lithium ion batteries don't get better after a few days and yes there are software fixes for battery life and bugs..

You really have no idea what you're talking about. First of all, it will get better, I won't bother explaining the science behind it considering you can do your own research, but it will, also, it can't be "fixed." Just like they can't make it an 8 mega pixel camera in an OTA. You can get it much better by doing custom roms and thigns of that nature.

It got better when I turned off vzw backup and google +.

Best I got is 16 hours bone stock just an extended battery. Worst I got was 4 hours(screen was on the whole time) watched 2 movies before I plugged in. I average around 12 hours from 100% to 20%.

First off, it's hard to tell by your screenshot how good or bad your battery life is. You're burning approximately 10%/hr, but maybe you had your screen on or were surfing the internet for a portion of that time. Anything that involves data transfer will kill your battery faster.
I got my Galaxy Nexus on Wednesday, and I've had great battery from the start. I calibrated it by letting the phone's initial charge die down to zero, and then charged it all the way up to 100%, and then used the Battery Calibration tool. I drain between 2-3% hour with light use, but can obviously drain much more depending on what I'm using the phone for.
That being said, for those on this board who think an OS upgrade is going to fix the problem, I highly doubt it. I have a reasonably poor cell signal (averages around -95 dbm), but still get solid battery life. Given that we were all issued phones with the same software, if you're experiencing incredibly bad battery life, I'm going to point my finger at the hardware. It just doesn't make sense that some of us with 4.0.2 get great battery life, and others do not. You probably have either a bad battery or a bad phone. Now, I'll probably get called out for saying this, but watch all the posts that follow when the update releases, when people still have poor battery life.
This is my 3rd Android phone (Incredible, Charge, GN), and every one of these phones has had poor battery life. On average, if I'm playing around with the screen on, I'm draining upwards of 10%/hr, if not more. But if you properly calibrate the battery - which is VERY important - you should easily be able to get a full day's charge out of your phone.
There is a post on XDA about the 13 steps to proper battery calibration. Once I followed it on my last phone, my battery life went up at least 50%. You have to let the battery drain to 100%, then bump charge a number of times, then use the battery calibrator.

Try running without JuiceDefender. Constantly toggling data on and off (or wifi on and off) actually hurts battery in almost all cases.

Your results may vary, but when I used Juice Defender or Green Power on my Droid Charge, I nearly doubled the battery life. I haven't put it on my GN yet because my battery life is much better than what I had with the Charge.

No using JD or anything like that. Just the the phone do its thing. I don't even open the multitask button unless I want to switch between apps.

Gotta be a software issue with the battery.
Just this past weekend in Wash DC. Very strong 4 G market.
I had it fully charged off charger. After 7 hours without touching the phone even with google plus sign out, the battery went from 100% to 54%. It's like the phone was active a lot without me even touching it. No SMS/mms either. No emails either.
Know. I did same thing and put it on airplane mode with it 100% charged. After 7 hours on airplane mode it was at 98%.
So it's gotta be an operating system issue.
I tried it on wifi instead of 4G mode. And battery drainage was down to 72% after no use overnight.

Anybody else enjoying the battery life?

Im so impressed! did have a s3, and I thought the battery wasnt very good with heavy usage. Fully charged it once, so its on its first cycle, and its lasting as if it will withstand heavy usage for most of the day

The battery is simply phenomenal.
I'm getting a full day of heavy usage on mine, around 7 hours screen time!!! I take it off charge around 7-8am and by the time I'm in bed at 1am it's ready to go on charge again. :good:

Does anyone stream their music? I take my OneS off the charger at 7 and the battery is pretty much dead by 1:30 pm with about 3-4 hours of streaming SiriusXM radio and some web browsing.

Hi all,
It's quite good. Better than Note 1.

I do a lot of gaming, web surfing, fb, txting, listening to music and it usually lasts almost 24h. It's quite good compared to the old phones I used. If you dont do as much as I do, it might last 2 days.

I actually love how long the battery last..

Limit the Note 2 from 1.6Ghz to 1.1Ghz with build in feature to save battery

I know most of you already notice this but if you don't:
In Setting/ Power saving mode, check the "CPU power saving" then your phone will be limit to 1.1GHz max from 1.6Ghz.
I would suggest to tick on the "Screen power saving", "background color" and "turn off haptic feedback" to save some extra juice.

LTE on. 24h unplugged. 75% screen brightness. Full heavy haptic feedback. Heavy gaming and Internet use. Phone calls. Texting. 3D live wallpaper. Still 7h screen on time before the phone finally had to be plugged in.
I don't know what you use your phone for but I'm going crazy on mine and can't kill the battery. If you need more juice, then more power to ya. I can't fathom why.

LOL I tried to kill mine but it out lasted me I woke up at 5 for work and by end of the day I went on a 2 hour gaming session to try and completely drain it and got it to 9% but it was like 10 and had work next day so gave up. I lost

I'm still suffering from battery OCD after coming from the iphone 4S. Now I feel like plugging in my note 2 whenever I'm at my desk at work.... So you guys don't think I need to?

Try a day without charging your phone at your desk. Yesterday I pulled in about 7 hours of on-screen time. That's with LTE and anything else internet intensive you could imagine. The only way you'll overcome that worry you have is to test it out yourself. I'm sure you won't be disappointed.

I'm with you. I came from the Skyrocket and it was a struggle to get through a full weekday on LTE. In the past week with the Note 2 I don't even have to think about charging it when I'm awake during the day. It's very liberating!

I would understand this philosophy if the Note 2 didn't have an easily replaceable battery, but in a years time you could replace a poor battery for cheap. Just recently the stand with extra battery and charger was $30 on the Samsung site (it may still be that price)

I think its my ocd from my note 1. Always seeking the longest battery life possible

Damn, I wish I could get run times like that. I usually get HSPA signal and after 16 hrs I'm dead with 4-5 hrs of screen on time. I mostly text and do web browsing. Maybe an hour of music with wifi on all the time and auto brightness. Still lasts longer than my SGS3 did.

My first charge is 7 hours screen time for 24 hours unplugged. Now it's going down hill to 4-4:30 hours after i rooted and remove bloats. Installed couple MoDs.. Dammed i wish i can go back to 7 hours screen time

You do know to "remove bloat" all you had to do was go into the stock app manager in settings and disable anything you didn't want. That is actually a much better solution than "freezing" with TiBu or removing altogether. I'm not convinced root and mods are 100% stable yet. Most people reporting decreased battery life are those that have rooted or modded something. I'm still 100% stock with ATT stuff disabled and batt life is still 7+ hours.

Even bare stock I wasn't getting that much screen on time. So far I've only rooted and changed the kernel. Though today my battery life is starting off good. Yesterday I ticked the power saving option for the screen. I'll post an update tomorrow.

Today I was on for 5.5 hours, screen time of 2.2 and was at 54% with Power Saving On
So I went to bell and grabbed another battery
Time will tell if that helps
I could never reach 5 hours of screen time but could have the phone on for 30+ hours
I cant wait till we get more developer support, I used Francos Kernel with my galaxy nexus and it improved battery by 30 % and made my 8 hours overnight use only 2% battery. I was using 12-17% overnight with my note 2 asleep. Aside from kernels and roms I use this phone exactly the same as I did my Nexus. wifi off, bt off, gps on, push email on, auto brightness

Lithium Ion batteries actually do better if you don't charge it constantly. In other words let it run down a bit before charging. You don't want to always keep "topping it off". But in general these batteries are much more resilient than others.
Just do some research. There's lots of info out there.

Umm, no, it does not. You are stressing the battery out. Unless needed, dont keep the battery below 20%. Its healthier to charge the phone sporatically throughout the day.
These aren't nickel batteries...they dont need to be trained or "cycled"

I'm a battery test engineer so I have played around with Li-ion batts.
If you can keep the phone at cool temperature and charge at 40% and stop at 80% then keep doing 40-80, your battery will last double long

Agreed. Full discharges are not necessary for lithium ion batteries. Full discharges were needed for NiCad or NiMH batteries as they suffered from memory effect. LithIon doesn't suffer from this. With that said, a lot of experts do suggest discharging a LithIon periodically, maybe once a month or every other month.

[Q] Bad battery life or device malfunction ?

Hello,
Some year ago or so I had a GNex on OTA 4.2.2 that I bought from ebay, and the battery life was terrible - some 4 hours of battery life which 80% was from the screen which I had on auto.
I also replaced the battery with one from a GS2 and the battery life did not improve.
I sold my LG G2 because the camera sucked, so I am considering buying a GNex again, so is this how the battery life is with the GNex on all? Or just my specific phone I had.
BTW I had the VZW model.

I get around 6 hours of battery life. Maybe some app was using up battery?

When im not overusing my phone i mostly can get through the whole day. Still battry life is not too great. But with some tweaks you can stretch it a bit.

I get 24-48hrs with light to moderate usage under poor cell coverage.

new note 7 battery life

Anyone got the replacement note 7 notice anything different in battery life with the upgraded fire proof battery?

i got one last night and cant tell any difference yet. it last just like my s7 edge did

it will probably take a few days for the battery to normalize after day to day usage before anyone can really report on it.

Getting poor life at moment, gsam showing deep sleep 0%. Install same apps as on old one not sure what's happening yet.

It took me a couple days before I actually got good battery life. Needs to set in, what I recommend doing is fully charge it and let it get down to in-between 1 and 5 percent before charging again. Don't do any in-between charging, at least that's what works for me.

My explodey Note 7 didn't get bad battery life at all. I couldn't complain one bit and was happy with it. This new Note 7 though... I think I got a real winner. It's less than 24 hours after switching and by this time of day I'm used to seeing the battery at about 62% give or take, but I'm at 84%. I'm sure it's placebo but I also feel this Note is just the tiny bit smoother and less laggy in the UI. Again, I had zero complaints about my first one so I suspect there's going to be sample variances across all spectrums with this.

This. Exactly my experience too. The replacement phone battery is a bit better (36 hours to go from 100% to 1% with moderate use, no gaming), phone doesn't seem laggy, and most important it does not get as warm as the old one did.
