Auto brightness.
Not to jack your thread.
But I used my iphone at work to watch videos, ect while there is downtime. I usually watch while it's also on the charger
For the Note series, does anyone know if that "kills" my battery for long term?
I know you can replace battery, but just wondering for future use.
Thanks.
Issue with battery drain due to android system is real
All three people I know that just got the Note 4 were experiencing the same issue I had with excess battery drain with the always generic "android system" taking more battery than anything else including the screen.
I downloaded an app called "System Tuner" and looked the CPU% for Android system and it was a constant 3-4% when the phone was otherwise idle.
I found a post at http://support.t-mobile.com/thread/80459 where they were experiencing the same issue (lose around 12% battery an hour with android system taking a huge chunk of battery). The person from that post was able to address the issue by turning location off, rebooting, turning location on, and rebooting again. After I did this I saw Android system idle at ~0.6% - 1.1% instead. So far I'm getting much better battery life but I'll need to give it some time to know for sure.
Hope this helps!
mine took about 2 full days for everything to finish syncing, downloading, indexing, etc. I had books, news articles, pinned music from google play, etc.
Once that happened, everything is now "normalized" and I'm getting better battery life than I was with the note 3.

Short answer: Maybe, it depends on how you are doing it. Using it while it is charging is not necessarily bad but watching videos and keeping it plugged in while the cell voltage is pegged at 100% will likely deteriorate your battery faster.
Long answer + tips:
Lithium ion batteries are great - they are light, can be made very thin and have excellent energy density but they are also very finiky.
Things to avoid doing with a lithium ion battery
-Charging to 100%, leaving it plugged in overnight is a poor practice(high cell voltages reduce the service life*, stopping the charge at 90%[4.10v] can double the service life, stopping the charge at 80%[4.00v] can quadruple the service life.*)
- Discharging the battery to below ~20% (Li-Ion batteries are somewhat sensitive to deep discharges)
-Charging/exposing Li-Ion to elevated temps or below freezing.
*service life is defined by when a battery can only retain 70% of its rated capacity. Most consumer batteries used in mobile devices have a service life of 500 charge discharge cycles.
It is not uncommon for batteries to lose 30% capacity in 1.5 years or less. Changing your charging and handling habits can double or quadruple a batteries life span.

LOL your picture took up have my damn screen on my 1080p laptop with 15.7 in screen. It was crystal clear too.
On my 2nd charge, auto brightness. Pretty freakin' amazing battery life....
15.5 hours off the charger with 8+ screen on time!
I got awful battery life on the first charge cycle. It drained 50% overnight. 2nd charge has lasted amazingly long and I still have 64% after 12hrs of average use.
First charge. Battery life has been phenomenal. Brightness on auto.
Did u use any power saving features to achieve that time?
Did u use any power saving features to achieve that time?
Definitely improve battery with recent update and I'm a power user
After the latest update
I dont know why but my phone goes from 100-90 in less than a hr with minimal use while the screen is set at auto, also in the leaving it unplugged in the night the battery also drains like 5 points.
I've been at full brightness and using the hell out of it non stop so far, and I'm at 35% with screen on time at 3hrs 40 min.

Just want to share my experience of 'best' charging method that can maximize the battery life of my Nexus one.
Firstly, let me introduce my equip:
- Machine: Nexus one
- Rom: FRF91 Stock, Deodexed, rooted, busybox... (Geo411m)
- Kernel: intersectRaven's 2.6.35_AVS-925mV_CFS_20100802_1056.zip
- Control: SetCPU, Interactive: 245-960Mhz when on, and 245-245 when screen off
The key method of obtaining max. battery life is the 'GOLDEN' time from 100% drop down to 99%. Once the battery shows dropping from 100 to 99%, the dropping speed is quite stably fast onwards
So, how to retain 100% longer before dropping to 99%? Below are the steps that really work for me:
1) Charge the phone to green light, some where between 90% and 100% (say: 95%)
2) Disconnect USB charging cable
3) Turn off the phone
4) Connect USB charging cable and charge the phone, it should show orange light
5) Set a timer, remember to *ONLY charge the phone for around 20-25mins*
6) The concept is NOT to charge the phone until you get green light. In order words, you need to charge the phone from 95% for 20-25mins where the light is kept ORANGE with the phone turned off!!!
7) After 20-25mins, disconnect USB cable and power on your nexus phone
8) You are done and the battery should last longer before dropping to 99%
9) Time in step (5) depends, you need to trial-&-error
For my experience, I normally charge the phone before I sleep and disconnect the charger. In the morning when I get up, it usually shows around 95% of battery. Then, I power off the phone and charge it. And then I take breakfast, bla bla bla ~ and after around 20mins, disconnect the charger and go to work. The battery can retain 100% for around 30mins of continuous web browsing, facebooking... and when I reach my office, sometimes, the battery still shows 100% !!!
So, above is my experience of how to maximize the 100% retaining time.
Please feel free to try and share with us whether it really works for you
Great advice.
Personally, I can't really be bothered with going out of my way to be overly concerned about battery life. I don't play games on my phone -- that will change when Angry Birds is released for Android -- nor do I watch movies, and I don't really do too much web browsing. Sometimes I listen to music, but not often.
I can go 12-14 hours of normal use (mostly Twitter and text messaging) and that will put me around 45-50%. I'm never somewhere that I can't charge the phone if I need to; USB at work, regular charge at home, and a charger in the car.
All of these tips and tricks for extending battery life are neat, but why bother?
^ Well looking at your usage, and the plenty charging points, of course you dont care. However, some ppl browse a lot, play games, so every last inch of battery life means something.
I just keep spare batteries in my pockets =D
I will try your golden tips.. then I will write my thoughts.
I thank you for sharing.
Screwing up the battery meter does not get you more battery life, period, and I suspect your shenanigans here is doing that. The battery has a set capacity, it's not going to charge more than that.
The Nexus One and a lot of other modern phones with modern batteries DO NOT trickle charge, they charge to 100% and STOP charging. When the phone drops to a certain limit, it charges more. Repeat as long as it's on the charger. This is why you might see it "drop a few percent" when you pull the charger.
Yea this sounds like a huge placebo effect.
Well I just did this, been off charger for over an hour.. still 100% after over an hour and two reboots.
At 1378mAh right now, didn't get a reading straight after first reboot unfortunately.
I'm also trialing autorun killer. Disabled a free services I don't use.. seemingly increased startup time.
heya,
Don't you mean decreased startup time?

How do you figure out your mAh level? Spare parts only shows me mV.

This is placebo. In the OP you even say after it finally drops to 99% it drops fast after that. It's because the phone wasn't at 100% all that time. It was giving you a false reading from messing with the charging pattern.
The best way I've found to charge the phone is to delete the battery stats, turn the phone off, and charge it until it's green. I get a great day of battery life with the phone that way.

Totally agree...I just charge when & where necessary and never worry about it! Don't have the time and it seems to last long enough for me to work & play
I had already discovered this and was looking for a fool proof way but I guess you beat me to it. Happens when you traveling alot. For me, I have gotten over 1500mAh more than once..some times 100% would last me half a day too. So it's worth it, my question is whether or not this is bad for your battery? or long term battery life.

I'm fairly sure that the Milliampere-hour (mAh) is the capacity of the battery (the amount of energy it will store). How can you get "over 1500mAh" on a 1400 mAh battery? None of you are making any sense what so ever. You can't get more energy out of a battery by charging it a specific way. If I gave you a bucket that held 10lbs of sand and you filled it with 8lbs of sand and waited a few minutes then started filling the rest slowly, it wont hold more sand. This is nothing more than a placebo effect. The only way to get more time from a battery is to reduce the amount of consumption. The only way to do that is to use your phone less or make your hardware use the battery less such as undervolting your CPU. I tried for the longest time to explain to people that underclocking your CPU does absolutely nothing. If you're still running at the same voltage you're still consuming the same amount of power.
Stop messing around with the battery and the battery stats.
Could someone please use the phone until it goes off in the evening? What percentage is shown on the batteryicon when it goes off? 20% or what?

That is exactly what I was thinking. I've never seen anything but increments of 10%.
No....I'm not talking about my battery percentage, I'm talking about my display percentage. Its always the higher of the four...wifi, phone idle and cell standby is always low, like in the single digits low. But the display is always high. Like for example I woke up this morning, checked what was consuming battery and the display was at 65%. If the phone was sleep for the past 4-5 hours thus the display not being on, the display shouldn't be consuming that much battery, so I thought.
I still get great battery life. Im just wondering if anyone else display is also consuming a lot battery and what could be causing it.

Considering you are getting good battery life and your display has that high of a percentage after "sleeping" that long is a good thing. That just means the other processes are running efficiently. You should always expect the Display to take up at least 60% of your battery, especially after a full cycle. What really matters is actual runtime.

Ok...thanks. I was just wondering.
Hello all, I would like to know what % to start charging my phone is better to the battery? it's draining so much and there is no extra battery for sell in my country yet.
I did search many posts and all answers are different. I am so serious only this and I hope I can have a better way to keep my battery longer... thanks for your attention.
it's usually not good to let the battery totally discharge. So charge it before it completely dies.
oh really... but I already made my Note battery to 0% and shut off itself two times I also did charge on 40-50% to 100% bcoz I know I would have to stay outside without battery charge after. I wish I can get an extra battery in my country soon.
Your problem is probably not related to the battery but to some apparently draining all the juice. There is an app called something like betterbatterystats, not sure on the spelling though, it might help you to find those draining apps. It's been reported manytimes here in XDA.
And for your information it's better to charge when the battery dies for the first couples of times. I don't think that it makes a big difference after that.

U may also want to check the process or apps running on the background?
I freezes all the unwanted apps or process les one by one to try it. But in terms of the batt usage, I believe if u don't use it much often u can still stand by for at least a day. Mine running on full 3G, but screen brightness set to lowest and STILL facing some batt drain issue.

Charging from a total 0 is actually good and most technical people will suggest the same. In fact a full battery drain every month and then a full charge ensures your battery gets a full charge and a complete battery rotation. This is a good thing that you did and let no one tell you otherwise.
However, for normal usage the lower the better at which point you charge is best.
All of these batteries comes with xx full cycle charges - meaning how many times they will last from 0 to 100% before they degrade and start giving less efficiency (around 85% on future charges) after the full cycle charges are over.
You may want to use 10% as a good benchmark to ensure you dont lose an important call with your phone off. The battery saving mode on the Note will also help you reduce loads at times and improve battery life (at cost of system power).
Congratulations on using the Galaxy Note, which I feel is the best all in one device in the market!

I second this.. its funny how still people still believe those myths about batteries (like charge 100% before you use the device first time).. those issues are easy 5-10 years old.. batteries now a days a have smart chips built into them that can control the battery health
So, I can charge my battery anytime when needed?
Also, for screen brightness, i set auto brightness is better than setting it manually low?

When my phone is fully charged or has 70 or 60% remaining battery it seems to drain as normal, around 2-5% over a 10 hour or so period...
However, I've noticed once the battery decreases below 50% it drains FAST, why?
Anyone else noticed this? Test it for yourselves, monitor the TIME it takes to decrease from 100 to 50% and then from 50% to 0.
Yesterday I forgot my phone in the car whilst going to work. It was turned on however it was sitting all day in the car.
Once I returned from work I was shocked to find the phone would not turn on.
At first I thought there was a problem or some kind of fault. Once I plugged in the charger it started to charge, the battery cut and the phone automatically turned off!
I remember the phone had around 48% battery remaining, no wifi or 3g or data turned on. It was simply idling...
So the question is HOW can the battery drain from 48% to 0% over a 10 hour period without being used???
Should my battery of been ANYTHING over 50% it would only lose a few percent...
Same thing for me. (Samsung Galaxy Note N7000 - stock Android 2.3.6)
Battery slowly decreases from 100% to ~50% and then ~2x faster.
I charged the note on my computer and then switched to the charger (at ~60% of charge).
I'm no expert of battery charging etc. but just remembered my iPhone 3GS discharging faster when charged on the computer than with the charger.
If it's the same for the note, some cells could discharge faster because charged on the computer.
Can someone confirm this (or not) ?
How did you charge your phone ?

Same thing happnd with me, and charging my phone thru electric charger..
So it seems this behaviour happens to several other Note users, why?
It's a problem knowing that having around 50% left in your battery will struggle to make it through the day with little to no use...
Have you people set the wifi to turn of while the screen is off? This is unnoticeable in the daily use, but increase the batterytime massively. The setting for this is hidden, you have to push menubutton while in the wifi-settings.
Here I thought I was only imagining things about the battery life dropping faster once it has reached 49% or less.

Haha, nice to know I'm not the ONLY one facing this bug...
I can only hope Ice Cream Sandwich solves this battery drain issue.
Hmm, i think i have the same problem, but i'm not sure. Will get back to this thread when i've investigated a little bit.
This may be a typical samsung issue.
I remember when i had the spica , the battery percentage lining in kernel was totally wrong. I think its done on purpose so you would feel like you have more battery life. 75 % of the battery drains slow. And the rest 25 super fast. Can be fixed within kernel.

I believe its just a placebo effect. Battery usage always depends on so many factors its a pain to even consider starting looking for the issue.
Being on stock KK5 not rooted, i cannot report the same. I only see "fast battery drain" at the last 4-5%. If you feel its an issue, could you post the firmware version you are on and the battery stats graph just for reference?
Placebo or not its something I can definitely feel on my Galaxy Note.

When you get the chance, could you post the battery stats graph please? what we should see is a (lets say) 30 degrees angle and at about halfway it gets steeper.
I know its quite hard to demonstrate the issue, but if you lets say use wifi to browse the first 50% in text only sites and then visit youtube for the last 50%, it won't help the test.
A nice way to test it would be to charge it to 100%, then load up a long movie and repeat playing it till the battery is 2-3%. Then post the results.

When the Wifi is disconnected, the 3G scanning will get on. Isn't that defeating the purpose?

Hey there!
I would suggest to load the battery 100%, plug it out, go into recovery and wipe battery stats.
I have to admit that I donĀ“t know exactly what this workaround does, but I read about it in another forum...and it worked for me, my battery status is much more accurate now!

I'm back. I've had the Diagnosis app running for the past hour, and i got some interesting results.
---Wiping battery stats does not help---, a full charge automatically causes battery stats reset.
I full charged mine with the electric charger after fully discharging it without turning it on.
This time i didn't notice any change in discharge speed between 100%-50% and 50%-0%.
Last time I charged the phone it was not fully discharged. Charged it from 30% to 50% then 50% to 75% on the computer, and 75% to 100% using electric charger.
It's just a supposition, but maybe doing several partial charges while using the phone makes the battery % information inaccurate (wrong battery stats?).
[Edit]In this case, wiping battery stats should show accurate battery %. [/Edit]
I had a similar problem, and I think it is to do with some incorrect scaling or measurement.
I was down to 28%, and it seemed to be draining fast even though I was not using it. I rebooted (I love how quick that is after my Arc was so slow). On restart it was at 17% ! The usage graph just did an instant drop.
I also had another occasion where it remained at 100% for 2 1/5 hours of use.
I assume some calibration issues caused the meter to read the battery wrong. I am turning off on the w/e overnight (when I do not need the alarm) to see if a slow (180 mA) charge while off will help. I may even get a decent alarm clock so I can turn the phone off at nights and charge. I spend too much time in the morning checking my email and reading news!
What is more consistent on mine is that when the battery drops to 9% or less the loss is like 1% per ~10-15% and this is with wifi/3g off, phone locked.
I'm back again. I've had some serious battery drain the last couple of days, but i noticed that Auto Sync was enabled. Once i deactivated it it got much better. Pulled the phone from the charger 9 hours ago and i'm at 90% battery left. I've sent some SMS, a few calls and that's about it, but it doesn't drain while it's in standby now, so i'm happy with it.
I apologize if this was asked before (I did a search of the forums but nothing really came up), but I'm wondering what others' experience with the battery life of the S4 is? This is my first smart phone and coming from a non-smartphone, I'm not sure if my expectations on battery life are unrealistic.
I got the S4 on 4/29 and brought it through one full charge cycle and several part cycles. Battery life is pretty important to me so I put an all black background (since its AMOLED), keep the brightness to below 10%, turn off all the fancy sensor things, turned on power saver mode, turn off wifi and data unless I really need to use it, turn off all sync so it only happens manually, etc. Yesterday, I charged it to 100% to see how long it would last and the stats I got were:
At 6% battery left, I had a total screen on-time of 2 hours and 58 mins and 1 d 2 hr on battery. Then, when I charged it to 100% and took out the charger, after about 5 minutes of it sleeping/screen off, the battery percentage dropped down to 97% with no data, no wifi, no active apps running.
With my pretty battery-friendly settings on my phone (or at least I think so), is this battery stat normal to others with this phone? Or do you think something might be wrong with the battery?
That sound horrible. There must be some rogue apps running/some wakelocks - try using better battery stats and find out.

Battery life is pretty important to me so I put an all black background (since its AMOLED), keep the brightness to below 10%, turn off all the fancy sensor things, turned on power saver mode, turn off wifi and data unless I really need to use it, turn off all sync so it only happens manually, etc. Yesterday, I charged it to 100% to see how long it would last and the stats I got were:
At 6% battery left, I had a total screen on-time of 2 hours and 58 mins and 1 d 2 hr on battery. Then, when I charged it to 100% and took out the charger, after about 5 minutes of it sleeping/screen off, the battery percentage dropped down to 97% with no data, no wifi, no active apps running.
With my pretty battery-friendly settings on my phone (or at least I think so), is this battery stat normal to others with this phone? Or do you think something might be wrong with the battery?

I apologize if this was asked before (I did a search of the forums but nothing really came up), but I'm wondering what others' experience with the battery life of the S4 is?

For a smartphone, an 'all-day' battery is fine, and given that the S4 has so many sensors, large screen and a powerful processor, I am happy with the battery lasting for 12-16 hours. I don't turn off any sensors, why get an S4 to run it on power saver mode and turn everything off? It defeats the purpose, in my opinion. I am trying to use as many features as possible on my S4. Of course, there are a few I don't, but just for personal preference. What you are doing is (no offence) in my opinion like getting a BMW M3 and running it on 4 pistons to save fuel.
Anyway, your battery life will improve after about 10-15 charge cycles, I noticed that with my past phones as well. If you need your battery to last longer, I would suggest getting a spare battery and keep it charged at all times for any emergencies. These are some of the reasons I love Samsung, removable batteries and microSD card slot.
thanks for the replies guys. I'll try the betterbatterystats app out. i'll probably take it back to sprint and see if they'll replace the battery for me. the screen accounts for about 50% of the battery usage in the stats and other apps take up the rest. the battery curve is pretty linear in a downward slope too (except when i don't use it at night, it becomes much flatter, albeit still downward).
haha its funny you say that, because i agree completely. the m3 is my dream car and if i could ever afford one, i would probably baby the crap out of it the reason why i got the s4 (and i also compared it to the htc one as a possible candidate) is because of the removable battery, sd card, nd most importantly: camera. that 13 megapixel shooter + hdr is really great for good photos on the go. speaking of which, i use the camera alot. is the physical use of the camera and the screen use a big power hog?

This is what I expect from S4
Google Services may be Google Now.....unless you use it, you can turn it off........
The phone only takes 1h 57 minutes to charge from flat. It's mad how fast thing thing charges from AC so battery life isn't really a problem. (yes I was sad enough to time it)
