What drains the battery? - XPERIA X1 General

Does an always on data connection (EDGE/3G/HSDPA) drain the battery more (even if its idle)?
Do applications (like opera) running in the background (just minimized) drain the battery more?
I think it might even save the battery if you say check some webpage 10 times a day and you have to wait for the browser to load and the data connection to connect and than close it all in the end. That would make things like GPRS autodissconect obsolete.
I know this may have been anwsered before but things like : meh i didnt notice beacuse i recharge it every day or saying its the same and worse in the same breath...........
If someone has the time and will to make a real test than please, I'm sure I'm not the only one who want to know this

first
yes
second
depend on if the browser is set to re get the page every X min to get updates

Maybe I didn't form the question right, so let me try to explain what is really bothering me:
How much drain doest it make? Will it be like 10% more a day or will the phone die in 12 hrs?
I cant really test this myself since I use it a lot (calls and other stuff) which is very irregular and I don't have a spare phone to do real testing on the xperia.

I always turn on the 3G and basically any programs that is internet based will drain the battery.

i posted lots of information here but was told that it would not be very accurate but i dunno http://forum.xda-developers.com/showthread.php?t=510754

Average Battery Life on T-mobile Wing

I was just wondering what is the average time of battery life on your wing..mines is currently about 10 hours idle but while im using it that goes down to about 5 or 4 i just wanted to know what is the average before i call t-mobile and ask for a new battery.
A few of us here have been having problems with the battery actually. When I first got the phone, I left it clean and stock. I would do a lot of texting, make a couple phone calls, and play a few games here and there. From 7am to 1am, I would go from 100% to about 54% (18 hours of usage). Now, if I leave my phone idle for 2 hours, my battery drops down from 100% to 80%... I can't even go a full day without needing to charge the darn thing. 200 hour idle time my arse!
But personally, I don't think it's a problem with the battery... The phone is doing something in the background which is causing a massive battery drain. Right now, I'm testing my phone to see if I still suffer the same drain while in flight mode. I'll post the results HERE in about an hour from now.
The longest the battery can last is 1 week...
On a full charge, you can talk for 5 hours...
the more features you use, the more power it'll consume.. if you do a lot of internet browsing, I believe I saw GPRS Data connections use more power then WiFi.. so use wifi when available ...
also, be sure to regularly check your phone's task manager before setting it aside for long periods of time... sometimes it can be hard to notice the camera, text/mms, calender, Internet Explorer, Windows Media Player, are all running in the background while you're at the home screen...
My wing usually lasts me from unplug at 8am until plugin at midnight... power usage always varies a lot as... as you can tell.. the data connections use a lot of power... and if wifi isn't available, it uses at least 30% more power doing a GPRS Transfer -- based on the initial information i've read about the issue.

I noticed Bluetooth and WiFi taking more battery than GPRS
As long as I plug it in while I am at work to a USB cable, I don't seem to have any battery problems. I use GPRS and SMS constantly.
I spend the whole day on the phone ... between texting and I receive all my work email directly to my phone... so I'm on it various times during the hour... and it seems the battery drain is huge.
all I have done is turn the screen brightness down whenever I'm not using it, and have the dynamic overclocking on, so the processor goes down whenever its not in use ... but I still think the battery drain on the wing is ridiculous.
Well david, overclocking doesnt help
Im clocked at 247mhz, i can make it last about 24 hours using it here and there. calls about once a hour for 5 min or less, texting through the day, and occasional wifi use. at stock clock speeds, it lasted about a day and a half, but it all depends how much you use it
At 1st i thought the battery darin was rediculous as well but when u think about it when u use it the battery goes down about 8 times as fast( depensing on what ur actually doing w/ it.
Now i charge it at night and go to school with fully loaded battery 6AM, i text all the time and when i get home its around 85% 2:30PM, use it occasionally and at the end of the day after at least 3 hours of talk time its on around 30-20% i could last w/o charging it but i charge it overnight to full, with NORMAL use and not talking for about 4 hours per day so far its lasted 4 days for me. could have made it to 6 but i wanted to showoof my new phone to my friend
so battery life is not that bad just depends how much u use it, Also if ur listening to music just turn off the screen and thats a REAL battery saver. also press the power button when on the phone and etc.
Wing Battery Drain
I have improved my Wing battery drain by doing the following...
- Turn off the automatic weather update on the Today Plug-in
- Check my emails manually (do send receive when I am ready to read)
- Suspend device when not in use - need to use device lock app.
- Update ROM to PDA Viet v 14 (thanks to easy instructions from David)
With the new ROM and the device locked - even the accidental press of any of the face buttons (when phone is in pocket) turns the device back on - even though the screen remains locked (due the Device lock app). Is there any way to suspend the device completely so can only be turned on by hitting the power button only? I would still want to receive / answer calls etc. without having to hit the power button....
Go to settings, Lock ... and there is an option to lock all buttons except the power button when device is powered down.
I am trying to fix my sisters Wing (I have a Wizard). I have tried disabling background programs, as well as setting things to be more gentle on power usage, and still she loses battery like crazy. I know the Wizard had some battery drain issues with certain WM6 cooked roms, and a cab fix helped. Does anyone have a cab fix for the Wing? Also, reading in this forum section, it seems that the Wing doesn't always disable background programs. Would you suggest a third party task manager to "pick up the slack" or does it not matter, due to the nature of the winged beast?
I appreciate any suggestions. While I am new to the Herald, I am "old hat" on the Wizard, so I do have a general understanding of how the HTC devices work.
Thank you in advance.
I have read a lot of bad stuff about battery life with every rom except the OME t-mo. I had the PDA viet and battery life was terrible, With the stock rom it is at least 4x longer.
hello ive the same problem with the last 4 wings ive and ever since ive switch from the stock Tmo OS and upgraded to the TouchFlo OS, Ive noticed a huge differnce with the battery life even overclocked
If your will to taking the risk ide say go for it, i jus started messing around with rom and i got say its a big improvment from the original wing which i was ready to throw against a wall!!
I have Touch Flo on my Wing, and if I charge it to capacity I usually only need to do so it every other day so long as I don't play any NES games on it. I keep the wifi off if I'm not using it of course. I have it dynamically stepping the CPU in a range from 100mhz to 234mhz. It really seems to help extend the battery for me, while still giving it the tiny extra kick it needs to run nes and sms games.
My wife has the official wm6 rom on hers, but is also dynamically overclocked as mine is. She needs to charge hers nightly, BUT she also plays solitaire and bubble breaker daily.
Overall it's on par for battery life with my prior motorola phone, which I never used for anything but regular phone calls. With that in mind I'm not necessarily impressed, but am definitely content with it.
I've had HORRIBLE battery life and AWESOME battery life, all within the same week. lol
There was a problem I had at one time, where filesys.exe would take over all the CPU and kill my battery.
Here's what I do, though.
Dynamic overclocking/underclocking
Turn off GPRS when not in use
Disable Push Mail
Turn off WIFI and Bluetooth
Turn the screen brightness down
Turn off the screen altogether, even when on a call, unless you need to see what's on it
There's a few tweaks out there that deal with enabling the power saving features on L2TP and stuff...
First post here-
I've had my wing about a week now and have a question concerning battery usage.
It has always been my understanding that batteries will develop a "memory" if you charge and recharge them under their full charge capacity.
i.e. if you use it down to 60% and then charge it to 100% it will remember that and not use the full original 100% charge. obviously over time not just from a single "half charge" like that.
So since every time you connect it to USB to sync it begins the charging process, won't that wear down the battery and make it develop such a memory?
Is their anyway to connect to to the PC without having it charge?
I have always preferred to have any mobile device drain it's battery to nearly empty before recharging to try and minimize the memory effect.
Thanks

Today's lithium ion batteries do not develop this like older rechargable batteries. You can plug your phone in at any time without worrying about losing battery capacity!
Thank chris30_2001, good to know.
oh and it's ALWAYS lupus
I listen to Streaming Radio with my Wing at work all day. I get approximately 4 hours of listening time before I have to swap out with another fully charged battery.
I use PBar to shut off the screen while listening.
I'm running the touch rom without the actual touch. I can't remember which one it is. I spend at least an hour a day gaming (text twist, random solitaires) on it. I usually hit up the web a few times a day for 10 minutes a shot. I use it as an ebook reader. I send txts constantly. I talk about half an hour a day. All this leaves me with about 30% - 50% of my battery by day's end. Now, if I turn on bluetooth all day it will end up around 18%. Wifi is such an evil power hog I never turn it on, EDGE is fast enough for me. I charge my every night under my pillow (it's my alarm too). Battery life has been the same since I got it about 6 months ago.
Edited to add: I also do some dynamic underclocking for things that don't need a huge amount of power, like my budget program, etc.

Battery Log (Please Help)

Hi all
At the moment I seem to be getting about 10hrs out of my battery that came with me brand new HD2!
I was told to upgrade my radio which i did to 2.08 and firmware which i did to ENERGY ROM 23544 but the battery life is the same, maybe i have a faulty battery!!!!
I just did a Battery Log and need your help in trying to find the problem and hopefully getting me to the point of my phone lasting 24hrs would be good!!!
the phone was put into standby mode and left yet it goes upto 200+mAh when the screen is off
ok i have email checked every 15min
no weather
no location
no facebook or twitter
just emails
wifi off
WMlongbatterylife installed so 2G all the time except when running certain apps which are not in use when in standby, I have emails to use on 2G
just cant understand why it can go to 12mAh in standby but not stay there,(in standby mode is 12mAh high)
ok a little increase but not 250+mAh, i could understand it being every 15mins for the email but its every couple of minutes!!
in taskmanager all that was in it for this test was active sync and arkswitch, plus batter Log v0.2.1.1
Please please help
Battery Log
Battery Test Graph
just in case the test was too small, i did a test on the 15th March which i will also upload just in case it can help, many thanks
15thMarch Bat Test
Way too short indeed. Make one over one whole day, or at least over 50% of the battery, and if possible tell when the phone is in standby and when in use, hard to guess what you're doing from the log.
I did Nothing, the 1st log was the phone in standby, the screen was off so why would it go up and down in the 2nd graph when its in stand by, its crazy that every couple of seconds it goes upto 200+ mAh
the short log and graph are the same time when the phone was in standby!!!
I meant on the longer log, the short one is too short to see much.
You certainly have some program that wakes up the device repeatedly to do whatever...
I have had my phone since december. My experience was also unforgivingly short battery time to start with, just as you have. My experience is however that the battery time has increased more or less continously up to now. Now it may last one full day, through the night and maybe all of next day (with moderate use and no automatic checks). Letting the battery down to 1-3% before charge did speed this process.
Where can I find such Battery Log / graph app ?
i did a bat log test last night when i was sleeping and if you could have a look at it when i post it that would be great i was sleeping so i do not understand why it shows a 150+mAh strange!!
all that is running is emails every 15mins i did a bat log test last night when i was sleeping and if you could have a look at it when i post it that would be great i was sleeping so i do not understand why it shows a 150+mAh strange!!
so to make clear, last night i was sleeping, phone in standby mode but i have emails every 15mins
no weather
no twitter
no FB
no location
wmlonglife installed
as far as i know its just emails are running every 15mins
when i go in task manager all that is there is active sync and bat log
but if i go in processes i see more
Bat Log App
Bat Log running all night when i was sleeping
These are the processes that were running
Wow, your nights are short
Anyway, there's something that prevents your HD2 from going to standby, as there's no "hole" in the log. I was suspecting it was the logging software itself (if it logs, the device must be running, right?)
But I tested it and it doesn't seem to cause trouble, see attached log. When the device is properly off, the log stops.
I also tried without logging but by watching the graph, knowing each square is 15secs by default (3x5), during a 10min standby the graph only advanced 15sec, so the time out of standby is minimal.

haha yes sad to say last night was short, head hit the pillow at 2am and was up at 6am
but thanks for replying
so like i said i have my emails downloaded every 15mins, could this stop my device going into standby??
i used to have it set up through gmail but with the bad battery time i thought i would try outlook, tried push which got them instantly but that was a shorter battery so now i am trying through outlook but every 15mins like i had before, but still just as bad!!
on all the logs i have done when i press my power key so my screen goes off and i do not touch my phone my mAh just never stays low, sometime over 200+mAh with the screen turned off so my battery just dies in 10hrs!!
as far as i know from the apps in task manager and the processes all i have running is my mail and the needed system processes so i am struggling, i would kill for it to last 24hrs and i never thought i would say that because that is still short i think!!
another 1350 extended battery on its way but i think no matter what battery i have if the phone is using upto 200+mAh in standby then it will just drain it too
please help as i am stuck now
I'd try getting rid of the programs that run (shakeandsave and possibly wmlonglife, one at a time).
If it still fails... well, reflash another ROM with the recommended radio, with prior mtty erase, then a good hard reset after flashing (read the flashing tutorials for those), and try again without installing any program.
Push should use less power as it only turns on and transfers data if needed, not every 15mins for nothing.
I run with data, wifi and push active 24/7, and a 8hr night only eats me 5-10% of battery.

Thanks for that great set of advice
not wanting to sound like a school yard kid being a copy cat but 5-10% sounds great to me, dont suppose i could know what ROM and Radio your running so i could try your setup....please!!!!!
thanks for all your help
Check my signature, the ROM already contains the appropriate radio and it works fine at least where I am.
Since your advice on removing WMlonglife i have a question
that app used to disconnect my internet connection when i finish with the internet or when it checked me email
but now because i do not have the app when i click the top bar on my home page it shows my internet connection and battery and always at the side of the top bar is the clock ticking away saying i have been connected for 13hours and increasing, now yes i have a unlimited internet kind of, its meant to be unlimited but they said its a 3GB limit and when i go over 3GB they will just decrease my internet speed, so i have no problem with it being connected all the time but wont that use my battery????
Nope, being connected all the time has no drawback that I could notice. And as you said they'll bother you if you transfer more than 3GB, time doesn't count.

Excellent, then i will let the time tick away since its not downloading anything unelss its fetching an actual email
in that case it looks like the problem for me was WMlonglife which is crazy since its an app to make battery life longer it did the opposite for me
i unplugged my phone from a full night charge at about 9am and now its nearly 4pm and i am on 88% with push email on and about an hours music and changing setting ang general going through the phone and replying to about 12 emails so far which i have recieved since taking my phone off charge!!
also 3G but no BT or wifi running!
if this keeps up i will easily get through a full day and now i have 2 batteries i think all is good
so thank you, thanks for the fast replies and all your help!!

Great, your battery life is even better than mine now

X10 battery lasts about 4 hours from 92% charge .. Wtf!!

Hey guys, , i apolagise in advanced if this topic is coverd, ive tryied to search but didnt find any related topics.....
Anyway...
I went to a 2 day festival took my x10 - WASTE OF TIME!!!!! couldnt even use it!!!!
Battery had died within first day, with hardly any use and 2nd day i had it charged for me up to 92%...
Checking the times every now and then on the 2nd day from 4pm onwards, i noticed by about 6pm my phone was on 50%, so i was curious about this as no wireless connectivity were turned on,
so at this time, i then "downloaded" from (GSM) not 3g. as coverage wasnt that good, advanced task killer.. i killed ALL my apps.. and carried on as normal, (only checking my phone for the time).. by 8pm i was getting messages saying 15% battery... and then 9pm my phone was dead :/ .......
No wifi, no internet surfing (apart from downloading advanced task killer) no bluetooth no gps..
Used my phone for a couple of text's and a couple of phone calls. NO WAY!!! should that have used all my battery up... Is their somthing i dont know about ??????
thanks
You gotta drain your battery s few times when you first get it. Also task killers don't really help with battery life. Imo they worsen it. Thirdly upgrade to the latest firmware

X10 battery issues has been covered big time
So has in call volume ...
I had the same first few days as you and was pretty dissapointed in the X10 but now things are much better. You do have to cycle the battery a couple of times and you'll see some improvement.
Most of the extra battery life really comes from using newer firmware. Since you didn't mention yours it's difficult to say if you are above or below 023. The 023 firmware seems to be the spot where most of the increased battery life came about.
Since I still wanted more I switched over to a 2600mAh battery from Cameron Sino. Now I have trouble killing the battery
There is something else that might be contributing to the problem... There are a number of apps and home screen widgets out there which are badly written and prevent the phone from sleeping, and therefore drain the battery like a *****... you should try a Factory Data Reset and then add your apps and widgets back in 1 or 2 per day until you have sussed what was causing it.. I had terrible trouble with Weather and Data widget killing my battery for a while..

Good point about the Widgets.
It would be nice, as a matter of fact, if there were a topic on Widgets that cause battery drain. I've read a few posts about specific widgets but have never seen an ongoing thread. I'm off to look for volunteers.
I seriously dont get these battery threads. I know this dosent help much, but I honestly get over 20 hours on a charge consistently, with WIFI and 3g on.
4h only?
Pretty much is a faulty battery/device.
I saw a movie with brightness at maximum using BT with wifi on at the same time and i still had 60%+ left.
Wow that sucks... I think your battery needs to be replaced.
Mine lasts about 4 DAYS
*#*#4636#*#*
Battery history and make sure the phone is sleeping when not in use.
If its showing 100% or close to 100% then an app or something is preventing your phone from properly sleeping.
!!
my personal experience on two batteries one 2 year old (from x1) and brand new one gave me 7 hours of intense usage wifi ( i don't use 3g ), texting gaming and in the mean time playing music after first update, before was maximum 5 hour , also need to mention i need to remove every task except what i'm working with task killer cause in my case every 2-3 hour for some odd reason i have at least 20 apps restarting again in the system which drain battery like hell , time scape and media scape use lots of battery life in auto connect mode so update it whenever u want them , gps is a drainer too i just use it when i'm desperate be careful some programs may automatically use gps without asking! also should say compare to x1 the speed of the lock is at least 10 times faster and not i can get it indoor near the window as well (its cool) !!!! hope energy roms come here as well cause they will blow your mind!
Just update to the latest firmware version and your battery life will be just fine.
If not you coul'd update your phone, root it, install setcpu, and get rid of Timescape & Mediascape.

Battery drain and 3G

G'day everyone,
I'm wondering if anyone has experienced a similar issue to what I'm having on my x10i.
I use to unplug my device from the charger around 7am (100% - fully charged) and the battery dies around 7pm. The main usage of my device is for making a couple of short phone calls, sending/receiving tens of SMSs, regularly checking my facebook, twitter and email account. Not a heavy usage I think, around 85% of the time is put on standby. I was really unsatisfied because my other device "HTC hero" stays for over two days. A few facts about my HTC Hero: 1) It is way much older and nearly damaged, 2) I am using it mainly for family/personal really long calls (30-45mins per call) and 3) Always connected to my car's built in phone system (Bluetooth is up all the time).
Since I bought my device 2 months ago, I was in a continues contact with SE the Middle East regarding battery issues. Honestly, they were very informative and respond quicker than any other company I dealt with before. They replied to me with really useful tips that extended my batter life to stay alive till the mid night (extra 4-5 hrs). Tips given were: Brightness automatic adjustment, Disabling auto Wifi detection... etc. Though, I was still not quite satisfied.
One day I decided to do my own experiments to observe the real problem with my x10 battery. This was 3 days ago. The first thing I started with, and apparently the last, was disabling the 3G service. I turned off the 3G service, and turned on the 2G (Edge) instead. Believe it or not, the first day my device's battery status was about ~85% when I got back home from work, ~70% at the mid night, ~55 percent when I woke up the next day, ~25% when I got back home, and dies around 8pm (from 17hrs to 37hrs). It was a straight shock to me. I already know that enabling 3G would shorten the battery life for both the short and long term, but honestly I wasn't expecting this much of difference in the daily usage. The other thing, I didn't notice any huge difference between before and now. Internet surfing is a bit slower, couldn't notice the difference. Twitter, Facebook and email worked just the same since I check them whenever I got notified. The last thing is I'm using mobile messenger now, i.e. eBuddy, since the battery is giving me longer time, and all my messenger accounts are on all the time.
Please, if you are having the same issue, let me know because I was assuming that there's something wrong on my device, either on the battery itself or the build software (build # R2BA024)
Regards
The improvements you're seeing are probably due to you living in an area with poor 3G reception. The poorer the signal is, the harder the phone has to work to maintain the connection, thus, eating battery faster.
Although, it shouldn't be THAT big of a battery loss... I'd look at what programs you have installed and running and see if any of them are secretly eating battery behind your back.
You should try installing and running "Data on demand" It switches your data connection off when the phones screen is off...
Its well worth upgrading to 026, i saw a huge increase in battery life from that.

Absolutely correct. At home I can leave my X10 for days without it dying with 3G enabled. At work there are dead zones that'll suck a phone dry within an 8 hour shift though. It's almost always a coverage issue.
For any battery issue I suggest a factory reset and THEN make the appropriate adjustments. Sounds useless but sometimes you can emulate all the same settings and things still don't happen as anticipated.
Use a 3G toggle widget for long periods where you KNOW it won't be necessary. Root your X10 and add SetCPU to that bad boy. Screw using task killers because the Android OS is *nix based and handles memory just fine - I only kill tasks before putting my phone away when I know I won't use it for an hour or more. Other than that, don't use task killers, battery monitors or anything that'll keep your phone from sleeping. Use Spare Parts if you need help identifying an annoying program too.
Thanks all for the useful comments.
Now, I feel more confident that I can keep the battery alive for even more than 2 days. Thanks for your information and knowledge : )
[Q]: Is there any application that shows (in bars or digits) the strength of 3G signal?

[Q] Unrooted Note 3 - Battery Drain, Most Tips didn't work.

Hi Guys,
Firstly, I know there are several threads with different tips and suggestions but most of them didn't work for me.
Recently (since more than a week) , I have noticed strange drain in battery and getting hot pretty quickly. It has kitkat and I didn't get time to use it properly in the beginning. After reading different threads and forums here's what I did:
- Let it drain completely, shut off, took out battery for a couple of hrs and then charged without switching on. x2
- Rebooted after charging
- Uninstalled some apps I thought might be problematic
- Factory Reset (such a pain!)
- When attached to Kies, it prompted for Firmware update N9005XXUENC2 followed by another factory reset and hard reset.
- Cleared cache by going into recovery mode.
- Rebooting after charging
But seems like none of it made much difference, my routine use
- couple of hours on wifi
- no heavy games, only temple run, subway surf etc.
- no streaming
- no lengthy calls, not a lot of messaging
- 1, 2 hrs of music
- Syncing off, gps off, blue tooth off, Wifi mostly off, power saving on, brightness on auto, no 3g/4g data, almost no photos and video capturing, sensors, motions off except smart stay
I don't want to root the phone because of my busy schedule, with some difficulty I was able install WLD on it which resets after Rebooting. Point is, I am not a heavy user and this being a "beast" isn't quite unleashing the beasty-battery-life. I do get more than a day but that is when it's in deep sleep for 20hrs or more. I took some screenshots after reseting, updating firmware. It's past 3 battery cycles now, I will attach the latest one's to not clutter it up. I like this phone, but this battery is just not good enough. So, please helpful answers that don't require rooting.
Thank you for reading and Good day!
Is the battery drain consistant or does it happen at certain times (at home, at work, etc.)? If you are in an area where the signal changes frequently that will drain the battery because the radio is using power to maintain a connection. With wifi scanning for google services even when turned off setting make sure it is off if you dont need it. How do you charge the phone? If possible always use the charger that came with the phone, charging from a usb port from a computer is not as strong and can affect the memory of the battery and do not wait till almost dead to charge. It works best to recharge when between 35% and 45%. Look at your background services and see if anything out of the ordinary is running. And it could be possible the battery is defective and you might want to have it tested. I use my Note3 lightly and get 24 to 25 hours over two to three days (turning off at bedtime). This may not help any but this is what I have learned from others with similar situations. Good luck!

Hey MPDnnrd,
Thank you for your response.
It is sort of consistent, did you see the screen is just at 18% and the Android system at 30%? I think this is where the core problem lies - just don't know what and how to fix it.
- Signal Strength: Pretty good, hasn't been a problem
- I normally keep the wifi-scanning off and Now I turned off the location services to see the impact but then I think what's the point of premium device if you have to switch off everything.
- I prefer to use the factory-charger over usb-charging and I read it on several threads to let it completely die and then recharge, guess that didn't help.
- Background services - I don't think so, I kill all the apps as soon as I stop using them, use Greenify to hibernate other, switched off all auto-updates and notifications. Even on Playstore, I switched off the auto-updates and notifications.
- Defective Battery: Now this one, I haven't tested yet not sure how to - the phone's just 2 months old so shouldn't it be good enough?
I know they are not very helpful, but still thank you very much. :good:

I'm sorry to have to say this but I think you got a pretty normal battery drain by looking on your screens. You played almost one hour subway surf(which drains the battery pretty quick) and I guess the other hours where internet (also known to drain battery) or calls/messages. On a not rooted device with stock kernel that seems like normal battery usage to me!!!
However if you like to check these maybe u get a couple of percentages(not that much though I guess):
-Power saving mode in notification drawer makes your cpu clock go down (not sure u got it on not rooted device sry)
-check turn of pen detection in s pen settings
-put the brightness on auto or put it down manually
-if you can change the theme color in apps do so(make it black)
-check the svoice settings so it doesn't listen to your voice
-if you don't care how your phone looks buy a zerolemon battery(I think it makes your phone too big but that's preference)
-don't use a bright background keep it dark colors and no live wallpaper as well
Maybe that helps a little.
I don't see any drain either. Almost 6 hours screen on during 24 hours is excellent, additional 1.5 hour awake time for other services. Excellent battery life.
Settings - General - Applications - disable unnecessary apps
In Google Settings, opt-out interest-based ads and disable location access.
Thank you for your reponses guys - thing is it actually had much better battery life. What I don't understand is the fact that Screen % used to be on top and android os and system was below it but now it has been on top.
I have tweaked quite a few things already that 4aces suggested and the S-voice thing seems new, I'll look at it. Today it didn't even last a full day whereas I know people who even after heavy usage get easily more than a day - mine one, I don't use it this much. The Zerolemon thing is beast but then the phone is a freakin block lol so heavy and big, good travel etc. where you can't charge your phone and has a rugged case.
But there's a change that I saw today, Android System is now below the screen so I am not sure what made it do that but may the next time I charge it gets better and so on. I'll keep you guys posted after charging it today, I'll monitor what I do.
Blondasisko - I wouldn't really call it excellent, but it's sort of getting better than it was in the first 2 cycles. But how do I reduce additional awake time for other services? Moreover, you might've noticed I got till 1% to get this much time like really stretched it to get there.
Someguyfromhell - Already done, locations were off starting today.
Can anyone else comment on their daily routine of usage and the battery drainage ratio?
If I get 12 hours and 4hrs screen time I'm happy. I don't even play any games. Have a lot of accounts syncing lot of Internet and a bit on the calls, gps. I get on average 14 -16 hours
I have brightness on high. If you put it on auto it makes a big difference.

I guess I should feel lucky, I have ZERO syncing, auto brightness, no live wallpapers or gimmicky stuff on, no gps, hardly 10mins or so on phone calls and prolly 30-60mins on messaging a day.
@all others - and the Android System is back on top - what could be the possible reasons for it?
I think its because of such minimal use that the system goes on top. The system still had to operate so when you have hardly used the phone then the system will go on top. Though with that usage you've stated you should get nearer 2 days really

You're right probably, this is what I'd like to know as to what is running in the background that drains more battery? Exactly, at-least 1.5 days is what I should get with this usage. May be I should buy a new battery and see how it works.
