[Q] Battery only getting around 6.3hr of total screen time? - Nexus 10 Q&A, Help & Troubleshooting

Hello my battery is only getting around 6.3 hrs of screen time total. I have read many threads about the battery time and a lot of ppl are getting 8-9 hrs of screen time. I have several questions.
1) I have only charged it 2x, I read that the battery life will get better after a couple of more charges. Is that true?
2) Ppl say it will get better after a couple of cycles, do they mean letting the battery run to 0% and then charge it all the way back to 100%?
3) I also read that I shouldn't charge to 100% every time , is this true?
4) Should I leave it on when charging?
My brightness is only set to 40%. My screen uses 65% android sys uses 9% and chrome uses 8% of the battery
Any advice to increase battery life is appreciated.
Sorry if the questions are repetitive, there are a lot of contradictory info, it is getting confusing.

Get a battery monitoring app & find out what's using most of the power. I use GSam Battery Monitor, and Better Battery Stats if your rooted. It will break everything down for you. The "app sucker" section within it tells you what % of power each app is using. Turn them off! Maps is usually always reporting your location, so turn off location service.
Your device has a Lithium-ion battery so no need to cycle it. Google: li-ion maintenance. I plug my devices in every time I see a micro-usb! Cycling refers to older ni-cad batteries.

Battery Charging question

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?

ICS Upgrade gives you a shorter battery life ??? Read how to get long battery life

Hello friends,
Here finally I upgraded to ICS and honestly I get great ( huge ) battery life..
before also I get upgrade and i get very low battery life because of low calibration of battery without my knowledge..
so I've reverted back to gingerbread 2.3.5 and I'm happy
But who wants older version when the new shiny and superb upgrade of ICS is there anyone ???
So finally I upgraded to ICS and after many searching ,, finding ,,, reading and confusion with doubt The great battery life will be came out from our Loving SGN.. so please do not get disappointed just see below.
Really here I provide you some small and very easy steps by using it you will be definitely be happy with your ICS upgrade ..
you doesn't have to go anywhere and doesn't have to buy anything with your valuable money ..
Really happy
Then read it and get longer and more juice from your battery..
you have to follow some easy steps below
1 . First upgrade your ICS from any source whichever you like ... by kies air or Kies on PC or mobile odin or Via PC ODIN [ please do full charge of battery before any upgrade low battery can make your phone unusable or dead you can get more info on other threads ]
2 . Hope you have upgraded successfully.. then use your phone till your battery goes down to 5 % or below...
[ Caution ] Do not use it till it switched off automatically.
3 . Plug your charger and charge it till morning if you are charging at night or else charge it around 6 to 7 Hours even after full charged .. it's important step.. Do not Ignore it ..
4 . and then use it as per your requirements till battery shows 5% or below
5 . Repeat the step 3
6 . Do it around 8 or more charging cycles.
You get really miracle after 3 or 4 full cycles...
[ caution ] do not overcharge after that i.e just do 6 to 7 hours charging for around 5 - 6 cycles ... after that charge till battery shows full charge i.e around 3 - 4 hours. do not overcharge ..
made it habit of full charge cycles if you are comfortable with it. it really gives great battery life then average battery life.
Hope It'll be helpful to you
Regards
It is better to charge randomly than doing full charges every time on Li-Ion batteries.
Doing full charges every time on Li-Ion will result in battery being end-of-life faster...
Overcharging is also bull****. The phone automatically stops charging the battery when it's fully charged.

As per research the full cycles of Li-on battery gives good hold of charge and also batter life..
in all honesty your post is as useless as mine right now.
According to me, It can be considered as myth . . If the battery needed to be calibrated then it must have been official.. n 2ndly the procedure above is not professional at all... So dnt even think it wud work.... Neways someone can always try and authenticate...:thumbup:

Doing full charges for calibrating the battery: no problem if you do it once in a while
But you are suggesting people to ALWAYS do full charges on their Li-Ion battery...
8-10 cycles after eachother is too much as well. 2 charges will be enough.
thanks for more info bro
maybe 2 is enough but in many cases it'll be not...
Why do you need to do this just because the OS has changed? And if so then why is it not require on GB?

I totally agree with you!
Also, never let a battery dry for long periods, it will be damaged beyond repair.
Lithium Ion batteries perform better when you keep it as charged as possible.
I call this thread BS too... But I thank the user for the effort
Yeah ICS battery life sucks. I've done what OP said and I still get 4 hours less Battery life than what gingerbread would give me.

It's essential because all the states of your battery will be wiped in most of the cases while you upgrade also it's helpful to you if you upgrade your ROM.

ok bro try this procedure and also report us..
In most of cases we have solved this issue with this procedure even i had this issue before now it works like a charm.
I did several full drain and full charge cycles when I upgraded to ICS. Still got the battery drain bug so I think its more luck than anything else if your battery lasts.
In my case I've discovered that power cycling the device after charging is the most reliable approach.
Install CPU Spy, run it after a charge, reset the timers, and then leave your phone in standby (screen off) for 30s or so. Unlock the phone again, and check CPU Spy - if the 'Deep Sleep' cycle is unused then do a phone restart. This has worked EVERY time for both me and a friend who I told about it. I'm getting similar battery performance to when I was running GB!
Battery life depends on a lot of things, ROM version is not the main thing.
This is my setup:
ICS version LQ3
Speedmod 3-3 Kernel
Disabled a lot of Samsung stuff (Readers hub, social hub...)
No automatic sync of twitter, e-mail, etc
I get pretty much zero battery drain when in deep sleep mode.
Of course when using the phone, screen on, Wifi On, autobrightness... battery usage is bigger and you can drain the battery in only 4 hours if you go for it.
Be careful with:
- Live wallpapers, I've seen cases where they remain active all the time
- Apps syncing data on background every few minutes (facebook, twitter, etc)
- Apps uploading a lot of data on background (google+, dropbox..)
- Games that crash and leave the CPU in a high power state until you reboot
Agree

I am agree with this reply.
If you want to get best battery back-up;
Disable all apps which are working in background, sync n update really eat the phone battery.
I am using my note with active mobile network or wi-fi for a whole day and playing games too without doing this F**KING trick.
The only way battery life gets sucked of Galaxy note is if it doesn't go into deep sleep when not in use.
To all those reporting low battery life: How much battery do you end up losing overnight. ( approx 6-8 hrs)
I typically lose <5 % ( best case scenario has been 1 %)
I had a problem last week and lost 30% overnight and found that it deep go into deep sleep.
and the best solution i found in another thread was to unlock the phone before unplugging from charger
Simply try it: For me normal time between charges is 36 hrs ( battery is near 25% level)

Many people are of the myth of overcharging n recharging, but its not true wIth lithium batteries, phone will automatically stop charging, if only anything helps its battery calibration,u can do this with a free app called battery calibration, time for the tread to be regarded as close, still useful for noobs

[Q] Battery life?

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.

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?

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)

Increased Battery Life

I am running CM10.1.3.1 with the nitest 7/20/2013 kernel and FC19 modem, on an Onite 1900 mAH battery.
I used many of the tips in this post;
http://forum.xda-developers.com/showthread.php?t=2357417
10 hours overnight with minimal usage, my battery now drops to 78% and shows 4 days 15 hours of similar usage before the battery will be drained fully. I've never, since buying the phone new, had better than 26 hours of stand-by time show up with a fully charged battery. I'm now showing 5 days.
Of course, screen usage is still the big impact, so actually using the phone drains it just as fast, but it is nice to know that, if I am not using it, I don't have to keep it plugged in all the time now.
I could be completely wrong about this but...
Have you been rebooting your phone? From what I've read rebooting the phone can throw off the battery stats. Basically the battery storage and usage is all the same its just the reporting thats off. I'm guessing battery stats get readjusted over time if the phone remains powered on.

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.
