i bought my phone in june and i was little bit angry to see, that the battery lasts only one day by normal using it without bt, wlan and gps only sometimes internet and phone. i went to my vendor and it was sent to htc 3 times to get it repaired back, but it still exists the battery problem. now i read, that some roms are less battery catcher than other. which rom is good for saaving battery life.
thank you very much or are there other tricks to improve battery life.

TC,
Are you using stock ROM or..? I've not change my phone's ROM yet and even until today, I get 3 days worth of normal usage (I charge my phone at about 20 ~ 35% range depending). I don't use it much for anything except being a phone, occasional web surfer, and very very importantly, an organizer/calender.
Also, do you leave applications running in the background? Do you close all of em? What is your brightness setting? How long does it take for your phone to dim the screen? Since I don't really care for 3G and HSDPA (couldn't even if I could), did you set it to GSM only? Do you turn off your phone module in signals with very low bars?
My point is, a lot of factors can affect battery drain, I hope the questions I've asked might help you better pinpoint what the problem seem to be. I wouldn't be surprised if the drain is due to the phone being in a constant 0 ~ 2 bar zone.
Cheers.
hello ,
thanks for writing back so fast
no i didn´t change or updated my rom with any roms which are able to be downloaded here. my phone was updatet when i brought it for analyzing in the htc shop.
i charge it always when it has nearly nothing anymore.
i use it for the same reasons you need. i use 3g because it was written, that gsm uses more battery than 3g
i always push down programs in the background only activesync is not easy to close
...... Do you turn off your phone module in signals with very low bars?
that i don´t know what you mean by "in signals with very low bars"
i also use mort player an windows player and by using these programs the battery drains a lot
thanks

Today I decided to do a real world test of the Evo's battery life. I used my phone the way I would normally use it on an other day. As for the phone itself, I am running the rom from the OTA update. The only changes that have been made is that I am using unrevoked root method so that I can use the Overclock Widget (marketplace) to turn the processor freq down to 245000 when the screen is off. I also use Advanced Task Killer to turn off apps that I am not using. I had bluetooth and gps turned on throughout the entirety of this test, wifi was on for about 3.5 hours. During this test I played a game for a short period of time, did some light web browsing, and had several phone conversations that totalled a little more than 2 hours. With doing all this, my battery lasted for a little more than 11 hours. That being said, under normal use the Evo should definitely last you throughout a full day.
Thanks for the info. I got my Evo yesterday and haven't been able to put it to through extreme testing yet
No problem. just kind of got tired of hearing how poor the battery life was. Even before using the overclock widget I was still getting decent battery life, but the overclock widget just put it over the top. To add to that, I don't normally talk for 2 hrs. on my phone during a normal day, so really a lot of that 29% battery drain from phone use wouldn't be there. The only thing I didn't use today was 4g (which I don't normally use unless I'm on the phone and need to use data).
Not sure what this proves or "dispells". When people (myself included until making some friendstream changes) are getting 6 hours out of a charge with light use, that is a real problem. You must not have friendstream syncing...if you did and did everything you just wrote about, your phone would be dead in 3 hours tops. Thanks for the info., but once again, people are havnig real issues with the battery...it's not made up.

If you are experiencing poor battery life then it is most likely attributed to not managing your apps properly (friendstream included). For example, without advanced task killer you will get a drastically different amount of battery life than if you have it. Then add to that, the way you configure advanced task killer can add a large amount of battery life compared to having advanced task killer without it being configured properly. Even with friendstream running you should still be able to get a decent amount of battery life (I am aware that it does use more juice), try having your facebook sync less often.

I totally agree I've been using my evo and been fine, I only really have it connected to power when I have it tethering. Besides that it lasts me not all day but while I'm at work (which is the most important part) I get a good 9-10 hours out of it before I really need to charge. It should also be noted that I use locale to switch BT and wifi off when I'm not in an area to take advantage of them.
I think some people have bad batterys/evo's, it's not just a matter of running the right programs or killing tasks

While that is possible I think the majority of the problem rests with the user's mismanagement of apps. I have seen way to many posts from people declaring the battery life to be so horrible, only to make a few changes and then turn around and say how much better it got. If that person had a bad battery then the battery would still have been bad, it wouldn't just start being good. That said, it is very possible that there are people with bad batteries. I just think that most of the people have good batteries and bad phone management.
I did pretty much the same thing. I have the O/C widget to set the frequency to 245000 when the screen is off and also have Advance Task Manager configured to close apps I'm not using. Helps out a lot and I usually get around 12~14 hours on a charge.

While I completely understand what you are saying, I can't really agree that b/c someone is not getting a full day out of their phone it is b/c of poor app management. While deleting facebook for sense, then reinstalling with only contacts synced fixed everything for me, the fact that you have to go through the phone with a fine tooth comb to get it to run more than 6 hours at a time is pretty silly. While doing that stuff is fine for me and most on this forum, it will undoubtedly turn a lot of non-techie people off from this phone...especially with Sprint doing their new 30 day full refund policy.
It's all good though, just plugged my phone in after 19 hours...playing with it most of the day.
I use advanced task killer and turned off sync for apps I dont use. At 65% used pandora (in 4g for about an hour), browsed several sites, made phone calls, text, emailed. All the normal stuff. Took my phone off the charger 15 hours ago.
Prior to using advanced task killer I would be to about 18% right now. So for those saying that task managers kill more battery power my phone seems to do the exact opposite.

Task killers really only help if you have an app that would normally be giving you higher than usual wake time (the calendar comes to mind). At the start of every boot I always make sure to kill everything so only essential apps and those I use are running. I don't use any kind of auto kill.

It is no longer recommended that a task killer be used. It may result in poor phone performance.
After i rooted with Toasts method, installed OMJ's rom removing all of the sprintware and added the OverClockWidget to tweak the processor, i was able to go a full 32 hours without charging. i had gps and bluetooth on the whole time and wifi on for several hours. i made calls, sent texts, took pictures, basically normal usage.
Just to add to all this. Bad battery isnt just a HTC Evo problem. Go read the forums of almost every android phone released and they all report the same things (in the beginning). Someone that has had a android phone in the past probably hasnt said much about battery. There are so many things you can do to increase battery.
1. manage your apps. Exit them instead of leaving them running (press back button until the app closes, or some apps you can Menu> exit) Pressing home doesnt close the app, it only takes you to the homescreen. Also change the sync times of all your apps/widgets. If you dont use gmail or google calendar, then uncheck the "sync" in Menu>accounts & sync> google. One last thing use a task manager (not recommended by some devs) I use it to end tasks of apps that use data, or ones that i use maybe once a day or once a week, i dont need them cached for quick returning, so i end the task all together. I ignore apps so they dont end that i use very frequently or ones that dont use data or run in the background.
2. Calibrate your battery once like so.. Charge your phone to 100% and then use your phone like normal until its so dead it shuts off by itself. Dont plug it into the computer or wall charger in that time. Then once it shuts off, plug the phone into a wall charger and charge it till its 100% again. After that, plug and play as much as you want.
3. Buy a car charger, usb cord for the comp, and maybe another wall charger. Buy an extra battery or extended battery. Doing the above and adding these to them, youll have a huge increase in battery.
I have an htc hero and i can get well over 12 hours of use by just watching what syncs and what uses data. And i use my phone alot, and wake it up a ton to check for notifications.
I use a friends Evo so im not new to the device and I understand its a different phone.
Stock htc phones come with a lot of stuff preinstalled and widgets. When signing into them with your accounts the sync times are usually pretty high, some like every 15mins. Watch what you are doing with the phone and youll have normal battery life.
i avg 18 -19 hours per charge so im very happy
aaaaah ok now I know who is the idiot Dylan here. Thanks. What a dumbass know-it-all.
I think some people are getting poor battery life because intermittent signal. I know this was the case for me. When I go to a friends house that I barely have signal, the phone constantly tries to find signal or goes into roaming. It would drain the battery fast. When I was in good signal area it seemed to last quite a while. Just saying that it is more than just running apps that cause poor battery.
Also if you will not use the internet turn off the mobile network, put the widget in your screen. You can receive calls but the internet is off.

You make a very good point. Weak/no signal areas will drain your battery (as with any phone) very quickly due to the phone constantly scanning for signal. Not really much you can due about that other than turning your phone radio off or switching carriers lol. One thing I've read in the Dev forum that may help you is to change your prl to the Alltell/Verizon prl. Some people have reported that this works well in low signal areas.
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.
I've been seeing a lot of posts on crap battery life around here, and I was chasing my tail about some of them as well, following a lot of misinformation even by senior members. I think I have a good handle on it now, and picked up most of these tips from these forums, so I'm not taking credit for these ideas, just collecting them in one place. Some of my suggestions assume you have root and Rom Manager (see the Tips and Tricks sticky thread on how to get them).
1. If your battery drains in less than a day on standby, you probably have a bad flash of the JI6 modem (either from the OTA update or from a ROM). Flash the JI2 modem from here "www dot teamwhiskey dot com/home/downloads". If the flash fixes it, you may try going back to JI6 if you want, and it may stay fixed. I went back to JI2 and didn't bother going back to JI6, but it has worked for others. With JI2 and 3G on I get just over 24 hours in normal usage.
2. The #2 battery drain on standby is 3G. I turned it off (Settings/Wireless/Mobile networks/Network mode/GSM only) and my phone lasted for 40 hours on Edge with light usage (few phone calls, messaging, quite a lot of web surfing, 2 hours of podcasts). Didn't even feel too slow (I get 140kbps on edge). Can anybody suggest a really good widget for turning 3G on/off? I use the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.
2.5. WiFi always on is a huge battery saver! It keeps 3g off. I can easily get 3+ days with light usage on my home wifi. Settings/Wireless and Network/Wifi Settings/Menu/Advanced/Wifi Sleep Policy/Never.
3. Don't need a task killer. I wasted all my time killing tasks trying to chase down my crappy battery usage, but since I fixed my modem and turned off 3G I know that the 3-5% CPU usage at idle does not hurt my battery. Taskiller for me was actually hitting the CPU constantly, lightly but for no reason, so I got pissed and uninstalled it.
4. Install a CPU usage monitor like Usage Timelines. It sits in the notification bar, very easy on the battery, but tells you if you have a rogue app pegging your CPU and draining your battery. These are the only apps you should be worried about killing. Astro File Manager has a task manager that shows CPU usage for each app, so you can kill the rogue one. I shoot for about 5% cpu usage at idle (at 200mhz - at 100mhz it would be a bit higher).
5. The app Autostarts lets you disable any app from starting on boot or other events like connectivity changes. This is not strictly necessary unless you have a lot of crap apps installed on your phone and they like to start themselves and waste CPU time behind your back.
6. If your battery reads less than 100% as soon as you unplug it from the charger fully charged, or your battery meter sits at 100% for a long time after you unplug it, you can recalibrate your battery meter. To recalibrate: 1) charge your battery to full, 2) unplug, 3) reboot into Clockwork Recovery and 4) Wipe battery stats.
7. There is No Such Thing as "battery reconditioning" (for all intents and purposes). The above procedure only RECALIBRATES you battery METER to read on a more linear scale between full and empty. It DOES NOT make your battery last longer, period. Whoever tells you that is a moron. If your battery is dying in 6 hours, doing any amount of calibration will not make it last longer (I've tried).
8. I wouldn't be too worried about undervolting, overclocking, kernel tricks and superawesomefast ROMS. The CPU drain at idle is so minuscule (as long as you don't have rogue apps) that those things make precious little difference. Like I said, the biggest drain is 3G and other radios. Having said that, I run Bionix 1.9 with the JAC kernel. It drained my battery in half a day at idle until I flashed the JI2 modem. With JI2 it suddenly started lasting over 24 hours, and once I turned off 3G, over 40 hours. I like this ROM and see no need to switch, it's very smooth. But you should be able to get similar battery life on a stock Vibrant.
9. I have GPS on, WiFi never sleep, auto-brightness, and a few widgets on like Weather and friend updates. I have no fancy settings, literally just turning off 3G (or wifi on, which is the same) got me 2-3 days. So I wouldn't waste time fooling around with magic settings (other than wifi never sleep), battery saver apps, etc.
10. If your screen is on all the time and you're playing games nonstop, you're draining your battery quicker than any of the things I mentioned above, so you probably don't care. In that case an optimized ROM/kernel is probably your best bet, especially JIT in Froyo. You can probably save on screen brightness as well.
If you guys have any other tips I'd be glad to add them to the list, but I hope this gives you an understanding of where your battery life is going. Basically: bad modem, 3G, or rogue apps.
Also, I hope this will put an end to trolls calling people whiners for complaining about battery life and saying unproductive **** like "you're a whiner" or "the Galaxy S is just a battery hog, live with it". It's not, you don't have to live with it, nobody should have to, here are your solutions.
Good luck.
A few things I do to help with battery life is:
Disable Audible touch tones
Disable Audible selection
Disable Haptic feedback
Disable SD card notifications
Set animations to NO animations
Uninstall media hub if you dont use it
Disable auto brightness adjustment
Disable power saving mode
I disable the last 2 and just swipe the notification bar to adjust brightness. Granted these items really only work when using the phone but I can go about 2 days of normal use without a charge believe it or not.
yeah disabling 3g has always been the best option for people really, really concerned with battery life.
But it's kinda hard to tell people not to use 3g on their brand new 3g capable devices.
You may want to add how to test if you battery is bad. If you use you phone repeatedly while it its plugged in you risk overheating and damaging your battery. Signs that unitas is the case are very quick drain and long (7 hours) charge times. You can easily test and see if your battery its damaged. Remove it from your phone and place on flat surface (e.g. Counter top) try spinning the battery. If it rotates easily and quickly you battery is bulging, this is a sign of damage. Time for a new battery.

Thanks to the OP and other contributors in this thread.
I flashed a ROM with the ji6 modem and battery life has been noticeably ****ty since. Example - this morning I unplugged my phone at 7:30 am. 100% charged. It's 10:21 am and my phone is at 75%
In the last 3 hours I browsed the web for 10 minutes while having my coffee and a smoke before heading out to work. Blue tooth was on for my drive, and I've sent 2 text messages. Aside from that my phone has been on stand-by since I unplugged it 3 hours ago.
I'm going to try to flash back to ji2 tonight as the battery usage was definitely better. Will also look into the 3G thing.
Thanks again.
You forgot to mention the two DRM and one downloader services that run resident on JI6.
These were the cause of my reduced battery life after I upgraded. Killing & removing these processes restored my battery life back to normal

I just tried this - switching 3G off works fine, but switching 3G back on didn't work for me. I had to re-boot to get 3G back so this is a no-go in my case.
I know how to kill the processes for the DRM and downloader but how do I remove them?
OP thank you for putting together the list. But I've never seen the point of doing all this. Its like getting a lamborghini and only driving 40mph because it you don't want to waste gas, whats the point? Either get a second wall charger to charge at work or a car charger. Heck even get a second battery if you are out for a long period of time.

You don't need to disable 3g.
The point of my post is to avoid people wasting their time with tweaks that have little to no effect on battery life. I'm telling people that they're wasting time killing apps and optimizing cpu usage and twiddling their settings when the radio drains most of their battery on standby anyway.
Meaning no matter what changes you make, you can only hope to improve your battery life by a tiny amount, because any other effect is overshadowed by 3G.
Put another way, you will NEVER get battery life much longer than a day if you're on 3g, so you're wasting your energy trying all kinds of tricks.

For me the widget did nothing. But it seems like it's not even supposed to turn the 3G radio off, but ALL APN network traffic. Did I miss something? It won't save battery power as long as the 3G radio is on.
I went back to the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.

While i understand the idea behind this thread, your conclusion is simple.
If you use the phone as a smartphone, it will eat up your battery no matter what.
I personally go through two batteries and some a day. (they cost about 12 bucks in ebay, and they work just fine)
The price for saving battery is not using the phone, and having a 400 bucks phone just for show off is just silly at least.
If you have a phone like this is to use it. At least you can change the battery not like some other devices......
I understand that task killer is useless, but do any of you use Autokiller (memory manager) ?
That's kind of a redundant question because even if you do not use the app, your phone is still performing the functions. The app just adjusts the settings. But to answer your question, using a memory optimization tool such as AutoKiller is 1000% more efficient than using a Task Killer. I don't think it effects battery much, but works wonders on performance.
There's no 3g-off widget because apparently in Android there's no way to do that through a direct command. I also use the Curvefish widget, and you are absolutely right about turning off 3g to save battery. I normally do so when I'm asleep or if I'm sitting at my desk next to a computer (why do I need fast data on my phone when I have my computer right here?).
The other thing I would recommend is AutoStarts. There are way too many apps that open themselves up at bizarre and inappropriate times. Autostarts is an easy and painless way to see which apps do this and keep them from opening.

Great battery life comes to people who hardly use their phones. Guess I need to get a netbook. Will prolly get a netbook or 3g laptop + skype and ETF my phone soon. These battery woes are show-stopping.

Losing 4% an hour on standby when you're not using the phone is unacceptable. Samsung screwed something up with the JI6 update. Most people think it's because of the stupid Media Hub. I think they are right.
People are not complaining about the poor battery life from using the phone. They are complaining about the slow battery drain even when they are not using it. ~4% an hour adds up fast. Vibrant is supposed to have 450 hour (18 days) stand-by time. That's what is rated. But people are getting 24 hour (1 day) stand-by time after JI6.

I'm not ready to sign off on this idea. For me simply flashing JI2 over JI6 fixed it. For some people flashing JI6 back over still left the problem fixed. I still have those processes running on JI2 and my battery life is fine.
The other reason I'm not ready to recommend wiping out those DRM processes is that apparently it stops the bundled Avatar movie from playing, and might affect other things that users may get pissed about. I've read that killing the downloader process people are talking about kills the market. So I really wish those people advocating that solution would figure their **** out and provide exact steps for the fix (right now their posts are really vague like "kill the processes that are named something like this" and not well tested; in all my research I didn't find the exact name of the "downloader" process).
Is it possible to flash the ji2 modem without root? Wishful thinking, I suppose..
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.
