Is this good battery life?

~15hrs life with display on 3 hours. Lots of text. Mostly using wifi ..3g for 2 hours. Lots of texts and ebuddy and some facebooking
A drop of Chuck Norris's semen was placed on the IPhone. We now have the Htc Evo.

Depending on the battery size assuming you have the standard: Yes, mostly due to the WiFi.
I don't know why the CDMA cell radio eats soo much of it up.

I'm currently at 62 hours of up time (came off the charger at the same time) with about 3.25 hours of actual screen on time. Mostly on wifi just as you. Ive had 6 phone calls, many text messages, and some basic screwing around on the phone and I'm only down to 36% battery so far. Stock red battery (1500 or 1600mah, whichever it is)

You mean to tell me you haven't charged your phone in over two days and you still have 36% left?

Yup. I kind of want to plug back in so I can transfer some stuff on and off the sd card, but I'm holding off because I want to see how far I can drag this out. Midnight tonight will be the 3 day mark.
The kernel I'm using is netarchy's 4.3-bfs-hvs-more-sbc.

Deathsled what ROM are you using?

my own, Jiminy V, but you probably won't be really interested in it unless you're on Cricket as it has all Sprint stuff yanked out. However, the Reengineered 3.70 rom (http://forum.xda-developers.com/showthread.php?t=878670) I would imagine would give you the same results as it was I used as my base rom.

I should try that out.. I always use cm6 and Zendroid bfs avs 844 245 smartass
A drop of Chuck Norris's semen was placed on the IPhone. We now have the Htc Evo.

I unplugged Sunday morning at 4:30 am. Monday at noon I was at 50%.
Now I really only used the phone to check facebook a few times, some emails, and what time the game started. Light texting and a few short calls.
The battery maintains very very well when you don't use it.
I am on latest fresh.

The sleep time on that kernel is great

about 4 hours. a little over an hour a day. I'm not glued to my phone like some of you guys are. It stays in my pocket and I pull it out to check the time or send a text message. It gets hundreds of 10-15 second bursts each day.
I'll admit that for the sake of seeing how far I could get the battery to stretch I haven't been sitting around watching youtube and playing angry birds all day....

looks better than what i get

Hah indeed, I lasted through a 3 day weekend drinking binge on one charge and it was amazing. Probably not half of that for screen on time. Its been said and I find it to be true, when not in use it does hold its own in terms of a charge.
I can't even imagine what my battery stats would be if I played games or watched videos, tbh. 24 hours with 3 or more hours of screen on time is good enough for me.
Had to ask, was only curious

That is rediculous! I wish the new EVO's could run custom kernals. I get about 15-20 hours with moderate to heavy use, which isnt bad but if I could get 2 days that would be great.

Its all based on usage. I tend to get 5-10 hours of usage (depending on what I am doing) That can be over a 12, 24, 48 hour period.
From what I see, its really based on how much you use it, and what you are doing.
On a full charge of the 1500 stock battery, I get 5.25 hours of video playback watching movies on a plane.

Now we all know the real test (mind u, I don't drive) is with having GPS on... b4 root having it on for a 40 min ride would eat up my battery entirely. Ouch that was painful to see.

Is anybody else using the LEAKED GINGERBREAD ROM on their EVO? Thoughts? Opinions???

I've been using it for 2 days and so far I have nothing but good things to say about it. The battery life so far has been top notch. My phone has currently been off the charger for 15 hours and 2 minutes, and I still have 41% battery left. It's very responsive. Everything works on my HW003 Evo. The one problem I have discovered so far is that when I record a video, once I'm done it force closes the video app. But the good thing is that the recorded video is saved intact and I can re-open my camcorder app immediately if I want to record another video. So it's really not a big issue. Other than that everything else sems to be working very smoothly. I have Go Launcher EX running on top of it and everything is super-fast. So far I'm really loving this leaked ROM. What about you guys(and girls)???

Well, I took it off the charger just after midnight last night, and I woke up at 7am. So 7 of those hours it was resting. But since then I've been to the gym and listened to music the whole time, sent a few texts, received about 30-40 texts from twitter, browsed the web for some of the links, viewed some android central youtube videos, updated some apps in the Market, made 2 phone calls, etc.. The point is with my last ROM and kernel, normally I'd be at about 15% battery by now.. There seems to be a noticeable improvement. But I posted this thread because I'm wondering if it's my imagination or if anyone else is having similar experiences.

A drop of Chuck Norris's semen was placed on Android OS. We now have CyanogenMod.

Where's a link for it? I wanna try this out and put in my .02!

Fyi my g1 only lasted 4-6 hours on a charge using stock battery, I turned off the radio and let it sit in my sock drawer it stayed on in stand by for nearly a week on that same battery.
These threads bragging about battery life are just BS, im sure if I want all day not using my evo I'd also get 16+ hours on a stock. I typically get a good 14-16 hours using my 3000 mAh battery and being constantly on my phone.
I noticed a lump in my battery last night (SBC maybe?) And now im back on the stock battery, this is my 3rd time today its back on the charger, my point? None but these threads don't mean a thing unless there's any really useful information to significantly extend the battery, especially to us users who do use our phones and not just let them sit idol all day.

If anyone says a phone can last more than 4-5 hours, then using a phone to them is turning the screen on to check the time, then quickly turning it off.
Anyways link? I wanna use Sense with Gingerbread.

He is obviously using his phone because 40 percent of it is the display

Last I checked there's a few in the development forum, but they are ports and a work in progress and have a lot of things broken. As son as there is a stable gingersense im all over that.

I loaded the leaked 2.3.3/sense 1.0 that tmartin put together. It is 100% functional for me. Some people were having issues with the screen staying at 100% brightness, and the camera acting strange. I think that may have been a variety of factors, wipe quality, hardware number, and screen type.
The rom was flawless for me. I have a 3500 battery and used my phone like a crackhead for 15.5 hours before the battery died. I was web surfing most of the time, and reading the leak thread that hit over a 1000 posts in a day before the op locked it up.
I am now using the misfit gingersense rom, and it is working 100% for me, apart from some very minor black on black text when word suggestions pop up using swype.

I flashed the tmartin 2.3.3 sense leak as well. I liked it for the most part...but it wasn't anything really special...some menu changes and it did have the nice fast boot feature. Sense was still a little sluggish when scrolling through home screens. I flashed back to cm7....what I do miss is the stable 4g that I do not get with cm7 final.

Wtf are you talking about!?
A drop of Chuck Norris's semen was placed on Android OS. We now have CyanogenMod.

This post was not just about battery life. That was just one aspect of it. I posted it to get feedback from others who are also running the ROM put together by TMartin from the leak. I still don't get why people get so funny acting when it comes to others talking about how long their battery lasts. If you don't like it or don't care to hear about it then move on, as it may not be for you. But others may be interested to see if it improves their battery life. Remember, every post here isn't catered just for you. The world is bigger than just you. Anyway, I use my phone quite regularly, whether it be browsing the web, viewing video, texting, listening to music, etc.
I also forgot to mention that I'm using the stock battery.
For those who asked where they can find the download, here ya go. It's linked in the first post:

Dude, your battery might have cancer. You should do a battery self-exam at least once every month. It's best that you do it in the shower so that the battery can hang low. Make sure you roll your battery through your fingers to check for any abnormal growth or lump.
If you feel a lump or that the shape of your battery has changed at all, don't hesitate to see your doctor. Remember, catching battery cancer in the earliest stages gives you a much better chance at survival!

I layed on a flat surface and noticed it rocked a little bit, so yea it has a slight deformity. Dr. Abu ghraib can have a look at it tomorrow.

I flashed it and been running it for a few hours now. Its alright, nothing ground breaking or impressive. Im kinda disappointed about no vertical battery or the on/tv off effect like the asop roms have. I thought I was gonna see that in gingersense. No big deal though, its same ol sense on gingerbread. I did notice some improvements in the browser. Fair enough, its cool, but still a little buggy.
Screen dimming works for me BTW, on my 0003.
Tomorrow will be the real test as far as the battery goes.

What bugs have you noticed?

Battery love (life) on VillainRom 1.4.0

So i'll cut to the chase, Battery has been ok with stock rom, after freezing the **** out of some apps, BUT, with VillainRom the phone is working perfect + battery life is amazing.
What is amazing?
53 Hours and 30 minutes since full charge.
I did charge it in the car for very short periods while using GPS and screen on full brightness.
How was the phone configured?
- Wifi/3G Data on at all times
- Push GMAIL and What'sapp
- Screen Brightness on full and the "Adjust screen power" option ticket off.
- Lookout installed and running in background.
- Bluetooth always on, not always connected though.
- 3 Hours of display usage
- 1.5 Hours of calls
- Some gaming, browsing etc.
Don't believe me?
Here are screenshots!

Thats really good but i couldn't get anywhere near that, not even without using the phone. I average no more than 10 hours.
Well done mate i wish i could manage it myself.

Anyway still don't understand what's good about this battery stats ...

@sumeshd,
You know, I don't get money from Samsung or anyone else for posting this? Why would I lie? Anyway, believe what you what, I really don't care that much.
I'll just say again, brightness is @ FULL.
3 Hours, is not ONLY, that's my usage, and you don't have to like it or not.
@bilboa1,
If I wanted, I can charge the phone almost 24/7 I got a charger my car, at home, at work, and even a portable solar one.
The charging peaks you see are mainly USB file transfers for a few minutes, and the long ones are around 30 minutes while driving with GPS + Screen at full brightness.
So the consumption on those moments is rather high, which means the battery isn't charging all that much.
@Mittaa,
You take a 4.3" Smartphone that does everything, and get 53 hours out of it, it's not enough??
if the little charging peaks were not there i'd still get around 46 hours from the phone, is that not enough???
Anyway the information I posted was to help people who are trying to choose a ROM, chose this one, or other people who are having battery problems have a reference.

eitama dont bother posting let this thread die please .
Two reasons one you will find certain users insist you have poor gps yellow screen bad battery life etc . Not worth bothering with if you are happy with your phone .
Reason two is a bit selfish as posting VR great battery life means we are going to get hundreds of numptys posting in VR rom thread who wont read and cannot follow instructions .

Nice to hear that your happy with your phone ... i'm happy too
I also understand that this is way better than your old desire HD (same for me moving from my old HTC Touch HD)
But I can't understand what this have to do with "whatever Vanilla Rom" ...
Lots of people can get this kind of battery live using stock unmodified, non rooted SGS2!
It could be very usefull if someone made a exact compare between two SGS2 running different ROMs.
First same configuration (screen brightness, auto update, widgets etc) then full charge.
Then 15 min GPS (same route), 15 min browsing WIFI (same websites), 15 min gaming (same game), 15 min talking (same person (sorry bad joke)).
Al together 1 hour of heavy identical usage.
Finally screenshots of battery stats and post here on XDA so we all can clap our hands for the best bettery saving ROM of the week

Well I tried to drain the battery on vr playing games etc to calibrate, and struggled, like noonski did.
I could drain stock rom with ease, but can't do it nearly as easily on vr.
The general consensus from reliable members like nobnut and jje seems to concur with it being better

well as I said I have tried all the roms..
I have tried vr4..for many days..it gave me 9+ hrs..
good u r supporting vr but not good that u r filling threads with "anything"
this is my battery with batista70 rom..and I m happiest with it..
PS: note the screen wake time bfor commenting..(its awake most of the time bcoz my heavy txting and use)..
and I am on 3g/h network with data active all the time..
this is the best I could get till now(with my usage)
no hard feelings..

People seem to be getting time between charges that vary wildly, but for me the biggest indication of battery life is obviously 'display on' time, and this seems to be roughly the same for the vast majority. Best I've seen so far is 4 hours, and that was mainly 3G/HSPDA browsing. My most recent however was slightly over 2 hours with VR 1.4, and again that was mainly browsing with data.
So while a screenie showing over 2 days may look impressive, it's how much actual use the user got that's important. The post above that showed over 6 hours was certainly impressive, but how much 3G browsing was done? How many 3D games played? GPS? etc etc

<shamed> - sorry for long post!!!
@ OP - you had a few minutes under 3hrs of charging. That is in excess of a full charge of the battery! And a total screen of a a few hours.. Nothing impressive at all. Saying you had on GPS and screen on full brightness negates the charging is just silly. It is usage, and usage is what we're interested in.
@ mittaa + Zedwings: Completely agree with both. Even display on (IMO the most accurate comparison) is a long way from the full truth for comparison in testing and a very fixed test environment would be needed to test a pattern of usage. I started to think about this like mitaa suggests (and when you do, you realise it is virtually impossible to co-ordinate without resetting back to factory) and there are still variables.
And anyway, it's kind of irrelevant at that point. You wouldn't consider doing it unless you're battery life is not meeting your hopes or needs. but your usage is your usage and you'll be happy or not.
Unless you are prepared to compromise on screen time, game playing, widgets, sync settings, live wallpaper etc, then what does it matter? You must find the balance between battery life and customisation that YOU can live with.
Personally, I do this by running my phone in 'full fat' mode. All radios on (this inc. GPS), synch on full, screen set to about 75% (no auto), the widgets I want, high spec live wallpaper (like Galaxies!) that make my £500 phone look like a £500 phone. I settle into my daily usage pattern, charging whenever I need to charge. This is why I bought my phone, not to immediately turn everything off and play the 'longest, littlest' game!
After about two weeks and this has settled into a fairly regular pattern, I start to switch off the things that mean least to me, one by one, day by day until after a numbers of days I find the balance that I can live with.
Personally I start with turning into perm 2G mode as I have wi-fi almost everywhere I go and I live in an area where 2G and 3G is on the cusp. This is extremely draining to batteries (I deal with none phone GSM equipment every day where battery life is key) and I know signal stregnth on the band you're using, constantly cylcing between band (and the variance in antenna power) is the single biggest thing to affect battery life asside from screen. It may not reflect this in stats, but trust me on this... If I lived and worked in a strong signal area, it would drop a few places down the list, extra call quality is nice as well as data.
For those of you living and working in London for example, but mostly out and away from Wi-fi, then consider leaving 3G on, and turning Wi-fi off.
Wi-fi scanning for networks constantly is another big drain.I have noticed this about Android, it allows you background apps to work leaner than the iPhone in power consumption when you have lots of widgets and synch etc. However the iPhone actually uses GSM to perform background tasks when the phone is off (shutting down wi-fi radio which reconnects as soon as you unlock the screen). This means that if you're out and away from a friendly hotspot all day, battery is less affected than an android.
Anyway, sorry for the long post, but hope you all have luck in finding your 'sweet spot' in usage / customisation.

Well, that's good. Recently I got a total of 16 hours including 57minutes screen on time.

3h screen time on is nothing, on 2-3 days it's called very light usage.

I got 56 minutes screen on time from my last full charge. Using VR 1.4.

Hi guys,
After buying s2 i was worried about battery life. Because first two days it was like 12-14 hours of medium use.
But now its marathon :d
See some shots..

Cheers guys and please show your records as well.

I thought i was getting good battery life with medium to heavy usage (27 hours) on Cognition 1.15 but that is exceptional, can you tell me your set up as to how you achieved this amount of battery life.
cheers

Tegrak's kernel and underclocked.
Frozen samsung apps. and brightness mostly 0% as i am fairly fine with the lowest brightness it doesn't hurt my eyes.
also one more thing, i am using overclocking upto 1300 as well and you will be surprised most people will tell you to go underclock to save battery but i didn't and i am just happy with 1.3 Ghz blazing speed.
Here's a shot of running.

Also i used camera for recording movie for about 50 minutes in 720P and 50+ photographs as well which is not mentioned in the above post. I will post once again when my battery will reach 1% because when its below 10% it drops really slow and allows me to use it more unlike when its full.

Sit it on a desk and stare at it. The average screen on time is 5 hrs. You can use that in a day or spread it across 3 days.

One more thing, i only recharge battery when its below 5% or mostly under 2% to full turning it off. And ofcourse this only first week of using the phone, hope it will increase a bit more by next week.
[Note: I personally believe plugging in and out of charger makes the phone battery drop faster]

You should blur out your IMEI number from the screenshot buddy.

What ROM are you using?
I usually have brightness set to auto, same as you all Samsung apps frozen, am not using Tegrak i don't believe it's compatible with Cognition ROM, are you using Juice Defender Ultimate or other apps,etc,etc, im on setcpu im 200 min - 800 max - on demand and screen off profile - 200 min - 500 max - consertivave - priority 100.
Seriously impressive all the same..

That is the best battery life ive ever seen on XDA for any type of smartphone never mind one like the GS2, did you use the Internet/Wi-Fi/GPS/Bluetooth,etc, much,do you have any widgets on your screen, push e-mail,etc, im amazed your getting that amount of time without using Juice defender or some other similar app.

Bluetooth yes for 10 minutes transfering some files.
Gps yes for around 1 hour (you can see that in pics atleast it shows usage for ndrive there)
wifi yes around 1 hour but its always on mostly (mostly used for market to download and test applications, gmailing and also some browsing)
3g or edge no i didn't use it.
Games yes i played like drag race etc.
widget yes, battery widget and the running app widget and live wallpapers.

Mine, I think there's a little (big) problem :
Considering the first 8 hours were during the night so I didn't touch my phone :
Running on VR2.1, many things push or so (like 15/30mins refresh) [mails, fb, twitter, news, weather, etc], and good modem (KG2) and CF-Root 4.1.
Any idea/advice please ?
A better rom maybe ?
Thanks in avance

For those of us n00bs here, what or where is the IMEI number?
Also just to clarify, this is a unique number for each phone, yes?

The real secret to great battery life is to disable all the data connections and not use the phone. Since most people are pretty active with their phones, threads about stand-by time are pretty meaningless. Actually, with over a dozen battery life threads already running, you could say new battery life thread are pretty meaningless too.

Ok thats along the lines of what I thought it was. Thanks.
Didn't know it was possible to change it, illigal. Huh
But can some one tell me where it is shown so I can block it if I ever post some screen shots?

I'm on stock K2-CL. I used 3G just a bit today while in a restaurant, wifi is always on, but I normally sit in front of the computer most of the day, or use my tablet at home, so I do very light surfing - mostly while on the can.
I've not installed "app freezers", nor underclocked the processor, nor rooted or removed anything that isn't stock android. Not stopping tasks in the task manager. In the screenshot below, I did play around a bit on Google Earth for 15 min or so, I'm surprised not to see the android market in there because I feel that's what I used most. I use a live wallpaper that's fairly bright (moving clouds).
Brightness on auto - automatic gmail notifications, contact syncs etc.
I'm going to go on a big trip next week, where electricity will sometimes be optional. I do have that Samsung battery case thinggie coming the mail next week - and already have an external battery as well for emergencies, because this phone will die in an hour or two using the gps, or playing games, or doing serious web surfing - or a combination of those things. It runs very hot too if you use it constantly several hours (drove 500 kilometers last week, the phone was very very hot - seemed unhealthy).

If you hold the power button along with the home button it takes a screen shot.
Thought id say to make it easier for ya in future!

thanks a millions

Don't mind the n00b Here.
Found the IMEI number in the status tab of about phone.
Goto remember to keep this out of public photos.

I Finally Did It! (24 Hour Battery)

I have been desperately trying for SEVERAL months to find a way to get my Samsung Epic to last ONE DAY. Many of you might say thats EASY but not for me. You see I am a POWER USER. Not one of those send a few text message, listen to some music, play a game or 2 users. I actually TALK on my phone a LOT.
I purchased a Yoobao 2800 MAH battery a couple months ago, thinking it would solve my problems and to my dismay I could ONLY get about 5-6 hours with the way I use my phone. So I began searching for apps and configurations that would help me achieve my 24 Hour goal and yesterday I finally found a configuration that works.....
My Results
Battery Life 25 Hours which included 4 HOURS OF ACTUAL TALK TIME W/ BLUETOOTH USAGE
Including 3 email accounts (2 Yahoo set to 1 hour check and 1 Corporate "PUSH" email)
A WHOLE GANG Of TEXT AND PICTURE MESSAGES...LOL
What I Have
Samsung Epic w/Yoobao 2800 MAH Battery
Running Stock Rooted EG22 (Leak) and Generation X "Green" theme.
What I used
Set CPU:
Set up profiles for maximum battery save when screen was OFF and when battery went below 30 percent
Juice defender (Free Version)
Tweaked for maximum efficiency using advanced settings
What I did
Themed everything as dark as possible (Go SMS Pro, Go Dialer, Go Contacts)
No Live wallpaper (Ovious...lol)
My Findings:
Contrary to popular belief....Tasks running in the background IS NOT the biggest source of battery drain. HAVING YOUR SCREEN ON IS! I was having NO success with any of the top task killers so I STOPPED USING THEM ALTOGETHER. All they seem to do is run constantly in the background (Even when the screen is off) killing apps that will RESTART themselves anyway after a few seconds. Juice defender works in a different way. By cutting off the data connection when the screen goes dark. That means any time Ii was on a call and the screen was dark, my data was cut off. (I dont usually need it when I am on the phone anyway) During this entire process I had a rather light wallpaper on my phone. so Im sure I could probably have saved a lil more battery if I wanted to.
Hopefully this will help some people get more battery life out of their epics. After all, whats the point in having a great phone if you can only use it (the way it was INTENDED) for a few hours.
Good Day To All!

lolz
im runnin ec05, srf1.2 rom, bright red & black theme(transmattered reds made by me) pulldown animation, stock battery, no memory mods, live wallpaper(my theme is mostly transparent so the live wallpaper is playing almost all the time), play pandora average of 4-5hrs a day, constantly checking fb xda email market(i have 120ish apps lol), & i get about 13hrs a charge...
you should try those changes on srf1.2 rom if you already havent... some people running similar setups have reported 2 full days or more...
but instead of set cpu you should try voltage control

Pretty sure when you get a phone call it shuts off 3G anyways. Atleast whenever My phone rings my 3G symbol vanishes completely.
Congrats on the 25hours though

I dont think thats true... I've been on a call using speakerphone and 4g data at the same time... I think 4g data still works if you are on a call

The key to good battery life is making sure your phone is sleeping properly when not in use. If CPU Spy shows 100Mhz much higher than deep sleep, then you got something that is keeping your phone from sleeping. I had a problem with some HP printer monitor on one of my computers pinging my phone constantly on my wifi network that would kill my battery if I let it sit with wifi on at home.

In the bottom right corner up there 1day 8 hours at 39%. I run srf, genocide, juwe ram tweaks, and set cpu with profiles to run the frequency lower as the day goes on.
Edit: I see now that that is a very ****ty picture. Man I just can't get screenshots right at all..
Cd's or tapes?

Talking on the phone and the 3g network use the same antenna, so you can only do one or the other. 4g and wifi use a different antenna so they will still work for data while on the phone.

Its not the antenna its the chipset. Bluetooth and wifi share the same antenna but both can be used at the same time.

After I flashed the EG22 Modem and Leak I had a 25 hr battery, but now I get about 10 hrs. Weird.

I have juice defender but I never use it.

I saw roughly the same thing. Incredible battery life for the first day or two, then it would refuse to charge either of two batteries past 60%.

Juice defender is good when you want your phone to control your data.

IS THAT WITH A STOCK BATTERY?!?
Thats unbelievable....

Until the newest RandomRom 2.3 Hawk I had the same problem trying to get my phone to last 24 hours. Now I have the RandomRom 2.3 Hawk installed with bloatware Removed, voodoo sound V9 module loaded, busy box pro and golauncher ex with over 100 apps also. 27 hours and I still have 14% battery life and that has been after using 4g for about 3 hours, flashlight for about 1 hour(teslaLED), played games for about 2 hours combined, sent about 40 emails, texted all day(about 150 texts), browsed the web for about 1 hour, watch some youtube videos for about 30 minutes and used navigation for about 30 minutes(coPilot). That is also with weather bug auto updating every hour and gmail sync'd to do its thing automatically. I am happier than I could ever describe now...I think I will finally leave my phone alone for a while now and stop flashing a million roms since I feel I have the best made for 2.3.4 now.

battery
I get about 18 to 20 hours of normal everyday use out of EG22 but i stay on wifi. on ec05 the most i could get is 6 hours, bottom line no matter what i tried. and thats with a stock battery.
