Could too enlighten me further what exactly is the 1500 battery?
Pooped from my Samsung Vibrant using XDA app...
Dont mind the skidmarks...

^ the stock battery is 1500...

Indeed I've gone overnight without a charge and heavy usage the next day and still wasn't 1/2 way depleted. I think the Super AMOLED has a lot to do with the awesome battery life.

"HEAVY usage" is relevant. I've had my Vibrant for 3 days and the battery is unimpressive to say the least. Hopefully, it will improve.

I am not sure what you have to do to prolong the battery life besides not doing anyhting, i.e. I was in the woods this weekend with no service at all, kept the phone in flight mode, used it to snap 3 pictures and 3 vids no more than 1 min each - the result is impressive - unplugged the phone at 7:30AM and by 4PM I had 70% left. Woohoo, I guess, the phone did nothing for 8.5 hours and only drained 30%.

I unplug my phone everyday around 6am and as of now, which is 7hours later I'm sitting at 92%.
What have I done on it as of today? 4 phone calls, 3 emails, took some photos.
Things I don't do all day.
Watch avatar over and over, let it idle on 3G for no reason, let it idle on wifi for no reason, turn off auto brightness.
I do have a regular schedule of charging.
I plug it in around 11pm turned off
I turn on my phone around 540am and leave it on the charger. I'm always greeted with the Its full unplug message around 6am.

how come your display use is only 8 percent mine is like 74 percent even tho i have it set on the lowest possible......

Thats saying out of all that time his phone has been on, his screen has been on 8% of the time.
If you use your screen a lot the number will be higher and I'm sure the more battery that would be used.

Great results so long as you don't need any network access for email accounts to work. That's not really an option for a lot of people. I have to have either 3G or WiFi on at all times to receive emails. SMS messages will come in over GSM so if that is what you do rather than email than you can turn off WiFi and 3G and still do texting.

Email works just fine over 2G (EDGE). I've found that setting it to 2G-only while keeping WiFi enabled (setting to stay on during standby) if in one location for a long time works better than keeping 3G enabled.

What is your build date? Find manufacturer date on box or inside phone.

I get good battery life... only gone down 1% since I unplugged it from being fully charged in 30 minutes with the display usage at 84% with GPS on.

yeah, tomorrow, i'll try to leave wifi and 3g on all day and come back with the result.

Checked my standby draining today. Lost 10% in 7 hours and 10 min. Look good, no ?
This is with: Google account sync calendar and contacts, push exchange email, 3g, auto sync
Must add that Tasker is also running and set to check everything to 30 min intervals

I have owned this phone since day one and am convinced that wifi is the biggest battery killer for me. I unplug it at 730am in the morning listen to live stream podcasts on the way to work and back (35 min commute). Make a few calls and texts, check all my normal websites on my breaks and when I get home at 630, I still have about 60%. In the settings I leave gps off and wifi on so when I get home its automatically on. By 930 the phone is at 15% so I am convinced its the wifi.
Having a screen this nice is worth the mediocre battery life, its actually better than my g1's battery life, so I am happy.

2800 Mah batteries on the way...

I'm not sure, I think it means of all the battery that has been used, 8% of it went to the screen. I would also like to know how you got that fantastic number! I usually have my brightness on minimum since I mostly use it indoors, and the screen is by far the largest consumer of battery power, even on days where I mostly listened to music (local, not net streaming) with the screen off...

I'm definitely getting better battery life out of this than my previous smart phones. Currently at 55% 1d20h unplugged. Light use, but still.

Crazy Android OS CPU usage

I am getting crazy CPU usage from Android OS, which is currently sitting at 52% battery usage. The CPU time of Android OS is between 20 and 30 minutes per hour! I have tried freezing many apps, I have tried task killers, rebooting etc. I have WKE7 firmware.

android os does use more than the rest, unsure why, but somehow the battery ife is still pretty good
http://goo.gl/cyd1T
KE7 (stock kernel) , full sync on google stuff + 1 email on push + auto brightness + about 1H of display on time on this, 1d20min and 68% left.
sent 3-4 sms and did a bit of various stuff since yesterday.
Seen worse lol

I would be very happy with that kind of batterylife. Sadly, my phone loses about 35% battery while I'm sleeping. With medium usage, I would usually reach 12 hours of battery.

i rate my battery life to smth like "amazing" xD

Yes for me battery life on sgs2 is also very nice - I'm comparing to sgs and it is about 20% better. My heavy usage today was 5 hours of screen on with wifi, some gps, 2h of gaming, skype running for about 3h, and battery run for total 9h. Also I use 2 push email accounts and sync is on. I think thats really good. And typically when I sleep in 8h battery is drained for about 8% with all email and google syncs active. So this is also quite good. All that on KE7. Most of samsung bloatware frozen.
Sent from my GT-I9100 using XDA App

Been trying to keep away from these battery threads, but noticed today that I've gone from android system 12% to 30% and I've no idea why.
Still on KE2, and am probably a "light user" - black wallpaper, brightness 20%, screen timeout 2 minutes, some phonecalls, lots of SMS, music - lots of Poweramp - shown a few photos, occasional wifi, GPS ca. 30 minutes per day, don't sync, don't use my carrier's dataplan, no e-mail as yet, and no Facebook/Twitter/games/Social hub/accuweather etc ever - in fact they were uninstalled on day 1.
Got 36 hours from my last charge, am now on 79% after 16 hours. Still happy with it, but no idea what has caused this spike.... Will keep an eye on it.
My $0.02 worth.

I am really starting to wonder why some people have amazing batterylife, while others are having terrible battery life. I would be very happy with 18 hours with 4 hours of screen usage, but instead I am barely scratching 12, today has been even worse. 10 hours with 3 hours screen usage...

So far mine is 2hr 15 mins screen on time, mostly browsing on 3G, 13 hours on battery, and have 29% remaining. Its OK, but I wouldn't describe it as amazing. Roll on 2.3.4

the thing is on android battery life largely depend on apps and setup anyway

Yeh, I know. But I feel like I have optimized my setup as much as I can. No autosynching, email check every 2 hours, facebook, twitter and RSS updates ever 4 hours. No GPS, automatic screen brightness, wifi sleep on. No widgets pulling real time info.

mine has the stock weather widget and animated background - also wifi always on (that prolly actually helps ..)
also i used some gps,played short videos, youtube, recorded some vids and took a few pics (you can see i used it more heavily today in the graph)
im supposing a lot of this goes as android system (bug?) cuz its certainly intensive and isnt in the list (not even lower)

Get rid of the auto screen brightness. I find brightness of 10% makes a huge difference. This samsung screen might look great but in fact it's practically useless as it drinks power

with ke7 as u can see auto brightness doesn't seem an issue for me anymore
i like it because i don't need to set the brightness in sunlight when it's auto hehe

What is your CPU time on Android OS vs. total battery time? Right now my phone has been on for 2 hours and 14 minutes, and CPU time in Android OS is 43 minutes!

If you've read through the majority of these threads, what's weird is that some of you that have uninstalled and/or frozen specific apps are getting worse battery times than those of us that are bone stock and have everything whirring in the background. As an example I use Wi-Fi a lot and also Kies Air and connect to a Blu-ray player using Wi-Fi Direct. The Wi-Fi Sharing app never appears in my running apps after I turn Wi-Fi off. Yet some of you with tweaks that don't use Wi-Fi have it randomly appearing and eating up CPU time.
I've kept up with this thread and other battery threads and for every "ah-ha!" moment there's a post following it showing worsening or no improvement. Somewhere in one of the three battery threads there were some tweets from Google acknowledging the problem in running 2.3.3. with dual-core processors. I think other than for the mad scientist fun factor we're just beating a dead horse and 2.3.4. is going to have to be our salvation. There's not even any assurance that a cooked ROM sans all the Samsung tweaks would work any better if the issue really is a core-OS problem.
Back to our ongoing debate...

[Test] Battery Draining

Ok, I've been thinking about this for a while now so I'm going to make a test to decide if I really need a battery saver. I'm making this test for myself purely but I thought someone might wanted to see the results as well so here we go.
The gear:
Samsung Galaxy S2, non-rooted
2000 mah Samsung battery
The competitors
Phone on its own
JuiceDefender Ultimate
GreenPower Free
The settings
Prefer Wifi over data
Connect every 30 min to sync
No night settings (to be fair against the others)
Screen brightness: Auto
I know the battery savers are made to save battery when not using your phone so the screen will be locked the phone only used for a small amount of time between chargings.
The phone is unplugged at 100% and I will continue down to 30% before charging again. I will only be testing each one once, as of now at least.
We'll see how it goes over the next days so feel free to ask questions and such.

Many people I know with an S2 use battery saving apps but i really see no point in them, when we used to compare our stock phones running the same stock ROM there was minimal battery difference. Haptic feedback will be off or on? That makes a big difference.
You should put in a custom ROM to see how much better it is compared to stock.
i look forward to seeing the results of this test though

If I got it correctly haptic feedback is phone vibration on touch, right? That's off at least, never liked it. I'd like to put a custom ROM but I don't want to root the phone, yet.. Maybe in a few months or a year...
I will be updating this as we go along. At the moment we are at 96% with 3 hours of sleep time and only a few minutes of screen time.

Ermm, can I ask does task killer drain your battery? Sorry if I ask the wrong question.

task killer will drain battery if the programs you closed restarts, use advance task killer and ignore those that do,you may need it for those apps that didnt close properly
im interested in your trial, juice defender service was failing to run on my s2, it ended up eating my battery restarting the service.
im looking to save power as i lose 15% over night with flight mode while i hear people lose 1,2%

Yes Android is a bit different than computer OS. To start an app drains more battery than just pushing the "back"-button and let it be in stand by so don't use task killers.
Yea I have had trouble some times with the battery saver draining quite a lot over the night but usually it has been because I had a mail as a widget with push-notification so the battery saver wouldn't disable internet but almost push all my other accounts as well. That was my solution at least. We'll see how this goes.
4h in 93% battery
15 min scrren time

A little update. You see where we are.

And does anyone know what can have caused this? This is a picture from a few days ago. It has happened maybe 10 times over the last 2 months. Simply the phone gets hot and the only way to unlock the screen is to remove the battery, refit it and then start it. And then it shows this massive drain.

Okay we got 1 day 13 hours down to 30% with 30 min of screen time. Next up is the Juice Defender Ultimate with night settings off.

An update for you all. As you can see JuiceDefender has already passed the "vanilla" time.

I had an odd problem. Sometime during night, the battery suddelny decided to drain at much faster rate and it took it only 6 hours or so to drain from 75% to 15%. I checked with BetterBatteryStats but there seems to be no app that has kept it awake. Anyway, I can't continue with this test spimply because I don't have time for reruns.
What I can say in previous experience:
Vanilla
Great that as soon as a message comes in you get notified immediately.
Unfortunately that's because wifi or data is kept on all the time, draining battery.
JuiceDefender
Usually gives my phone 3-4 days of battery.
It does take some time (up to 15 sec or so) when you unlock the screen to connect and that can be annoying if you are in a hurry.
When I have night settings on to set phone in no vibration, no sound but also have different night setting time for weekends the phone vibrates once at midnight between weekdays and what JuiceDefender recognizes as weekend.
Sometimes it doesn't feel like the apps are updating even though settings are set to allow "dumb apps" to update as well as plenty of time to do so.
GreenPower
I have only had time to use it for a few days and it is only the free version. I will probably buy the premium soon.
It has a better UI than JuiceDefender though not so many settings. I'm not really sure if I need those other settings.
Best thing, it connects instantly to data when I unlock the phone so I can get on to the web or viber or such to see messages directly.
If anyone wants to continue this thread you may do so but I won't make more test as for the moment. Bottom line is that the data turning off when phone's locked really do help with battery life.

Moto X 1st Gen Battery issue.

I've been experiencing serious battery drain lately.
Lasts around 6 hours tops.
Check out the stats. Anyone know how to prevent this?
Drain is almost 3:40 min / 1% discharge.

Check if your phone turns off the display after the display timeout. I have seen this happen in Moto X sometimes.. It just stays awake. Restart fixes it.
How about brightness? Set it in Auto Brightness mode. Check your Settings->Display page and check all the fields. Apart from that Screen taking 38% is surprising.

I've been having the same problem. I updated a bunch of apps yesterday, (mostly Google apps) and it the battery seems to be better today. It may be too early to tell, but I'm hoping it was one of the Google apps that draining the battery and that it was corrected with the update.

Glad to see I'm not the only one who's battery suddenly got a lot worse. I thought it was Snapchat since I had started using it recently, but the battery usage page doesn't reflect that.

One thing to check is the awake time. If you notice that your device seems to be awake all the time, I'm willing to bet that it has to do with google play services.
If rooted, there is an easy fix via gservices app on market.

I'm having the same issue. Really only getting about an hour of screen time these days. When I first got the phone it was 2+ hours. Mostly use WiFi vs cellular for data, which I thought should be more battery friendly. I make sure I don't have apps running... I'm thinking maybe my battery has just been getting weaker over time.
Here's a good read on battery wear http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
If you charge once a day like everyone the battery decreases by 15% after a year.

Brightness is already set to auto. Also, I've check the settings and display page. Its as it should. I wiped out cache partition and it improved a little. Though I didn't saw significant change by doing that. It still runs for max 6-7 hours. That's it.

Doesn't actually do anything. People need to stop facilitating this dumb myth.
Google said:
This file [batterystats.bin] is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings. That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you. It has no impact on your battery life.

May be u need to calibrate your battery. Try to put the phone in charge and let it reach 100% and post that dont remove the charger for 4-5 hours. This is a method to calibrate. Try this and lets see if it helps.
And, I see that you are in H+.. Try using your phone in 2G for a day and observe the battery patterns.

You should clean battery stats from recovery.. Have you tried this?

Mine will drain fast but then it will sit at 1% for several hours before finally shutting off. I have not found a fix and it's been going on for a few months now.

u let the battery die out then recharge to full without switching it on. Once complete boot the phone and when booting is complete then remove the charging cable.

[RESEARCH] Zenfone 5 1.2Ghz Screen On Time

As the title said, I'm gathering some information about screen on time (SOT) of Zenfone 5 1.2Ghz (from 100 to 1-5 percent)
I want to see how my battery is after years by how much time it can handle now. Hope you guys help me.
In comment section, please including your SOT plus:
- What rom are you using? (Kernel version if can)
- Most used network: Wifi or Cellular
- Network setting: Always on or Never (Manually)
- App ram usage (Running Service in Setting/Battery or Develop Options)
Thats all I want to know for now.
Thanks!

Using stock rom Kitkat newest version, cause it uses much less battery!
I mostly use more of the Wi-Fi on always on
what is mostly using my ram is the screen ( brightness) and android
I will send more information about RAM usage later, my phone is recharging

Using 1.6ghz variant.
rom- resurrection remix nougat. but channging of roms didnt had any great impact
only wifi always on.
ram- 40-50% or below free.
sot i get varies from 2hr- 3hrs. only texting and light stuff gives around 2hr 40mins.

im using latest kitkat on my 3 years old zenfone 5 single sim variant.
this one with 100% cpu usage all time + [ full screen brightness+ bluetooth + wifi+ gps on ] from 100% to 5%;

Screen was always on in both tests. i used battery drain app to make screen always on with full brightness and wifi in second test and i get 3h45m screen time.
in first test i pushed cpu 100% and activated all gps/bluetooth/wifi etc and i get 1h53m screen time. but phone was really overheated and i scare to do it again (it was burning my hand)
actually i was shocked myself when i saw 4 h screen time when i used my phone to only read ebook all day in home with half brightness and i decided to test my phone. Results were amazing i agree, i hope it keeps that way for one more year.
i tested overnight battery usage and it dropped to 85% from 100% within 7 hours with wireless open while android sleep. i guess it might be better to close all network overnights

I wish I still kept the screenshot on Mashmallow to show you.
wireless is not the reason but the google play service. After disable a list of unneeded services, I let wireless enable all the time, gmail and other notification still can be recieved and battery drained 1% per hour (screen off). For specifically, after 6 hours over night, it will drain 6%.
screen on time is normally 3 hours but of course I have to tweak a lot to get this result. If not, battery just drains like hell.

i tried to close wifi yesterday , as you mentioned it does not effect the drain.
3 hours sot on marshmallow is great but unfortunately i cant use custom roms cuz i need Gps occasionaly and my simcard often keep loosing signal on thoose . i am considering to get a xiaomi mi or redmi phone by next year but until that i had to use asus zf5 with kitkat 4.4.2 and 3-3.5 sot is best i can wish for.
