Wow, you graph shows the battery falling like a rock based on display usage.

+1 on the "without providing details of what was done over those 5 days."
[Galaxy S II General] turborider:
lol he charged the phone while is on,dont believe it :p
[Galaxy S II General] kreoXDA:
That graph was after testing how long I can go with screen on full time. The screen was displaying a pitch black image, and not much else was done on the phone. Not real usage of course. More like a proof that displaying a black image does eat power. I had posted before a similar test with gray image, that one was eating even more power.
[Galaxy S II General] BarryH_GEG:
At least it's nice and linear. ;)
[Galaxy S II General] intruda119:
Average screen on time is about 4-5 hours. No matter if that 1 day or strectch to 2-3 days. My battery last a full day 7-6 with about 30-40% of battery left. To me thats excellent. If I needed anything more than that I would switch to a blackberrry.

I have the luxury of plugging my phone in at work, car and at home.

Of course he didn't use it at all. Display 8%. rest my case.
[Galaxy S II General] kbiz90:
Well, prodygee is either joking or serious. He doesn't seem like an idiot.

I'm not on my phone all the time. Sometimes I don't use it for an entire day (well, I've been using my SGS2 every day so far). My holy grail is to take it off the charger when I leave work on Friday and not have to worry about it until Monday morning with moderate use. Is that so wrong? :D
[Galaxy S II General] puremind:
It gives you an idea of maximum stand-by time. I find it actually quite interesting to compare maximum standby time across multiple ROM's and Modem versions.

It is also intersting to see if the drain is constant with each ROM or if there is an acceleration of drain. On some ROM's the drain was 4ma, on others I get 2ma with some peak periods of crazy drains without synch or fancy widgets.

On my last Hong Kong ROM I get 2ma drain without any crazy drain periods during standby.

I am now on 3 days and 3 hours, with 50% battery remaining, so theoretically should reach 6 days. Wifi was on 30% of the time (as WiFi was identified as a potential culprit) and phone awake 40% of the time.
[Galaxy S II General] bhogal:
Work this one out !?

Hi people,

A rather weird occurrence here [ maybe it is normal with Android ? ]

Since going into standby my GS2 has actually GAINED 3% in 2 hours :D:D:confused:

What on earth is going on here ?

This is the first time since I have owned a phone of any sort that I have seen the battery GAINING charge while in standby !!
[Galaxy S II General] kreoXDA:
It actually happens often, especially with not well calibrated batteries. If you discharge quickly (for example with a heavy game), and then switch into idle mode, your graph will show a rapid fall (game playing), and then a slight increase (idle mode, the batt had time to cool down and properly evaluate its drain)
[Galaxy S II General] matanc1:
Is it normal that the battery drain is 20% or so for watching videos over wifi for 1 hour or so?

I'm trying to understand if I'm expecting more than what the phone needs to supply or if something is actually wrong.....

Can anyone give some general battery time stats?

I've heard 4 hours of screen on.

Is that with Wifi? Without Wifi? With Auto-Sync? etc
[Galaxy S II General] Isadora:
I'm at 5h40 screen on (2% battery left!) Mostly browsing, brightness on auto, Wi-fi on, auto sync and a bunch of rss feeds updating every hour.

Edit: I'm on KF3 rooted, not KF2
[Galaxy S II General] galinha:
What rom are you using ?
[Galaxy S II General] JupiterdroidXDA:
Thats average,

most of our screen time on is playing games, and that is cpu intensive, especially when overclocking to 1.5ghz....

Too many different factors to consider, these posts are useless;) It always makes me laugh to see posts like this, because every phone is the same practically, its only the tings you do while running it which is the delimiting factor. Samsung batteries seem to be very good across the board, HTC batteries are total garbage!

[Galaxy S II General] clax6:
I think the battery readings on thisa phone may be too advanced. Its hard to explain what im trying to say but ill give it a go. If you go to bed at 12 with a full charge and leave it on then you will get say 20 hrs till zero.

But if you unplug from a full charge when you get up in the morning at say 7am and use the phone the same the battery will not last as long ? Its as if the standby uses no power but still registers as up time hence why peoples battery times are so different

Hope that made sense
[Galaxy S II General] Isadora:
I know, I just decided to throw more meaningless figures at already meaningless statistics :D

Had a HD2 before so I'm *extremely* pleased at the battery life I'm getting on the GS2 based on my normal usage :p
[Galaxy S II General] Isadora:
Stock :eek:
[Galaxy S II General] JupiterdroidXDA:
Sorry I wasn't aiming that post at you, I just find it amusing in general, I think we have all been guilty of posting our wonderful battery lives.. if you want to extend your battery even further download battery calibrator app, charge to full and then press calibrate, then unplug, drain it to death then charge fully again. After this your phone will last even longer;)))

screen on time heavv use 4 hours ?

Im new to android and after tinkering and tweaking my s2 Iv come to not like the battery life. Is 4 to 5 screen on time for heavy use really good? Im not familiar with smartphones but 4 to 5 hours heavy use seems pretty bad for me. I love the phone but its sad that I cant really use its features much browsing , playing a games for an hour or 2. I have never owned an iphone but I hear its got decent life. I do own an Ipad and obviously it cant be compared to a phone but that thing last for days with some gaming too. I just wish my galaxy s2 cud be that way cuz the phone is so cool.
[Galaxy S II General] JupiterdroidXDA:
Well 4 to 5 hours screen on time is the norm mate. Just get used to charging your phone in the night and you will never run out of battery. If you would ever have used the original HTC desire you would know about terrible battery life, 8 hours Max, your battery would be dead by 3pm;( this phone is a beast in comparison, and also think how much more it does than iOS, this phone is basically a laptop in your pocket;) I get 4 hours but I'm overclocking to 1.52 and overclocking my gpu too, and running a constant live wallpaper;)

I bought this phone to be the juicest fastest most powerful beast on the block, I don't see the point in some of these guys buying the sgs2 and undervolting and underclocking, they might as well have bought a HTC Legend;P

Yea the phone is a total beast! think I will buy an external battery pack. Does anyone know if using the phone while connected to an external battery pack will heat the phone up like when im charging through the plug?
[Galaxy S II General] RogerPodacter:
I think its pretty bad too, but it is normal unfortunately. Only one other phone out there gets way higher, around 10 hours screen time, and I won't mention the name:).
[Galaxy S II General] JupiterdroidXDA:
Its because iOS basically does nothing, its a total idle inert process. Its Androids stupid brother that gets fed less because it does jack, haha.. no lwp, no Widgets, no external SD, no true multitasking. It does nada, just sits there and drools, lol

[Galaxy S II General] RogerPodacter:
i dont buy that argument, and i contend to you to setup any android phone stock, factory reset, use airplane mode, remove every single app possible from the phone, do ANYTHING you need to remove all from an android phone, and then do a test. it will still not come close.

the reason is simple, apple just optimized the hardware to a much larger degree than any one android manufacturer is capable of doing. apple has one device, so they tweaked the hell out of it to maximize power consumption.
[Galaxy S II General] saifbechan:
I am not too pleased with the battery life either, espesially when i use voip apps.
[Galaxy S II General] aussiebum:
It's not just that imo. It also helps tremendously that the phone which should not be named happens to have a much smaller 3.5 inch screen vs. the huge 4.3 inch the SGS2 has, while at the same time having similar battery sizes (1500mah vs 1650mah).

Plus of course, the fact that iOS apps are heavily restricted on what they're allowed to do compared to Android apps. Which means they're less likely to eat up your battery because they're likely to be less poor written / optimised.
[Galaxy S II General] Roman5:
Why can't they make batteries at least twice the capacity, over 3000mah, is it just not possible or would it mean the battery would need to be physically much larger?
[Galaxy S II General] Sleepycat3:
Not really. They optimised the software (when I say optimise, I mean neuter). Here at work we just moved from dumb phones and personal android phones to the iPhone4. Interesting comment from one of the i5700 users who moved to iPhone4 is that the standby time is good but when you use the phone for phone calls, the battery life is poor compared to his 1 year old i5700. So it does point out to the iPhone4 having software that tries to minimise running processes when it is in standby but when it is actually used, turns out to be similar or worse than the other smartphones out there.
[Galaxy S II General] goodwinod:

[Galaxy S II General] THUDUK:
I have just been sat here for 45 mins and the battery is now at 80% gps off, screen at lowest brightness, wifi on all im doing is reading the xda app, just just crap
[Galaxy S II General] Pume:
Have you got push email accounts, exchange account in particular. That seems to be the biggest battery hog for me... disabling push I went from about 14h to 2d :)
[Galaxy S II General] tjtj4444:
For heavy usage the screen power consumption is dominating. And a 4.3 display has 50% larger surface than a 3.5 display, so assuming the same display technology a 4.3 display consumes 50% more power than a 3.5 display.

I know that "the big competitor with a 3.5 inch display" uses a different display technology but that doesn't change the general relation between power and display size.

A SGS2 with 3.5'' display and single core cortex A9 process @ 1GHz would probably have similar battery time as the "competitor" and still have great performance.
[Galaxy S II General] ithehappy:

[Galaxy S II General] rudolf895:
One general question..

As the above screenshot(post #62)

the signal is green half way then yellow

Mine is always yellow, Does it mean i have poor signal?

Or does green indicate flight mode
[Galaxy S II General] AllWin:
I believe it shows type of connection (2G, 3G and so on).
[Galaxy S II General] kreoXDA:
Your picture shows that you lost 3% in 8 hours with Wifi off, and packet data off, and that means sync off. And your display is at bare minimum.

There is nothing unusual with this. If you lost less than 1% with this usage than I would have been surprised. ;)
[Galaxy S II General] RogerPodacter:
i would agree with that. but i take my nexus one with a 3.7 inch screen, barely larger than apple's 3.5 inch screen. hell its OLED too so it should help with dark pixels colors. and it has less pixels overall compared to the 960x640 of the apple screen.

and both have near identical battery sizes.

i take these 2 devices side by side, and the iphone 4 destroys the nexus one if you do a browsing test side by side, click link by link, for 30 minutes of testing. the n1 should get similar results, but for some reason it doesnt.

the iphone 4 can get 10 hours of screen on time with wifi web browsing. the nexus one can only do about 5 hours of wifi web browsing.
[Galaxy S II General] rudolf895:
Hope your right thanks :-)

Tapatalked from my super smooth, ultra fast samsung galaxy s2.
[Galaxy S II General] ithehappy:
It doesn't have anything to do with 2G/3G. Green means strong signal, Yellow means medium, I don't know if there is a red color also exist or not. Mine is always on 2G and I get Green bar 70% of time and yellow on existing.

Regards.
[Galaxy S II General] rudolf895:
oh, if this is the case then i have yellow always! Never seen green :D

This means that i have poor signal and thus maybe the reason for the battery drain?
[Galaxy S II General] Jasonhunterx:
Oh no not this **** agian ok there is 1 iphone so it is very optimized wait until ics comes out when everything is more unified an optimized
[Galaxy S II General] ithehappy:
Well I also have Yellow line. But not always. I am not even in the middle of the city. I think yes, searching for medium signaled network will take more battery than strong one, but I don't think it is that noticeable.
[Nexus One Q&A, Help & Troubleshooting] SmallWalrus:
I'm currently running with a rooted version of the latest stock firmware on my N1, and I love the stability and all, except Google's apps2sd implementation is really dumb.

Hey SmallWalrus,

I am running stock 2.3.4 unrooted Nexus one. (yes, that is GRJ22)

I have never rooted a phone. Can you please point me somewhere which shows how to unlock and root the N1 with my specs. My phone is pretty old. I am only rooting it because this is a spare one and I now have moved to SGS2.

PS: using a mac and Linux machine. If not then please show me a windows one. i'll try dual booting my macbook pro.
[Nexus One Q&A, Help & Troubleshooting] SmallWalrus:
Have you unlocked your bootloader? That was how I did it though, there is no other way to root 2.3.4 without doing this at the moment.
[Nexus One Q&A, Help & Troubleshooting] painkilleryusuf:
That is what i want to know. How do i do that safely?
[Nexus One Q&A, Help & Troubleshooting] elyz2:
Well there is a way to safely root your phone without unlocking the bootloader, I did those steps recently and they worked fine for me.

1. You need to downgrade your phone to Froyo. Get the FRG83 image from here: http://xdaforums.com/wiki/index.php?title=Nexus_One/Roms

Rename it to PASSIMG.zip and copy it to the root folder of your SD Card. Boot your phone into the bootloader and flash the image. This will wipe your device, so be sure to make a backup of your data and apps first.

2. Use SuperOneClick to root your phone. http://xdaforums.com/showthread.php?t=803682

3. Now you need to flash a custom recovery. I used the Clockworkmod one, because flashing it is very simple: install the Rom Manager app from the market, it has an option to flash the recovery.

4. Now you are set to flash custom ROMs, either through Rom Manager or the Recovery. You should however do a Nandroid Backup first, in case anything goes wrong in flashing the ROM. Boot into Recovery and you should see a menu item saying Backup or something.

It's really not a big deal as it sounds, I can't guarantee that this will work for you. You should know what you are doing and if you feel unsafe about any of these steps, make sure to search the forums or the web about it, before you execute it.
[Nexus One Q&A, Help & Troubleshooting] SmallWalrus:
Sorry, I didn't see your question until now :)

Actually, it IS very easy to do this, you can find the instructions here:

http://android.modaco.com/topic/299078-how-to-unlock-the-bootloader-on-your-nexus-one/

It does have some warranty implications though, but since I am already using an import set I don't care. According to some, HTC usually shuts one eye and fix your phone's hardware failures even if it has an unlocked bootloader, but YMMV.
[Eee Pad Transformer Themes and Apps] Magnesus:
Is there at least one music player that is using the screen estate of the tablet? Like with columns and such? I'm searching for something useful but it's frustrating. The default player doesn't see my CIFS shares and is buggy, Winamp, PowerAMP - don't see CIFS shares and are more for phones than tablets...

A player that opens folder (but not scanes them - it takes too long on CIFS) would be best (there is app called "folder player" but it's for phones, scans for ages every time I start it and doesn't want to close).

A player that scans a CIFS share but doesn't loose the library when CIFS is not available (so it doesn't have to rescan every time I restart the app and forget to mount shares) would be even better.
[Eee Pad Transformer Themes and Apps] jonitfcfan:
Don't know if this will work for you or not, but I just came across something called Hive Player Lite in the Market. Try this and see what happens...

[Eee Pad Transformer Themes and Apps] redshirt72:
I have no idea on the sharing aspect, but in terms of using screen real estate for pretty pictures, Fede(the launcherpro dev) has made a music player called ubermusic, looks really nice on the tablet since its a copy of WP7 music's look, which I am a fan of. ubermusic.com to get it to sideload, since I don't believe its on Android market yet.

[T-Mobile LG G2x] jland22:
Not sure what caused this, I crack flash CM nightlies, constantly convert partitions from ext-3 to ext-4 using beta kernels and at some point in between lost the ability for any computer to recognize my phone mounting (both internal and external). Tried three different computers, two different cables, swapped sd cards, reformatting card and nothing... All that happens when plugging into computer is a charge symbol.

My SD card is accessible through file managers and is mounted just fine to phone (accurate storage space). So I took it into Tmobile and they overnight-ed me a new g2x phone which is expected to come Monday. Claimed it was a hardware failure and acknowledged I had a custom rom and to make sure I put the stock one back :). The only problem it is impossible to get the stock recovery image and remove root without a computer so I will be sending them a rooted stock rom with custom recovery. Hopefully they don't charge me for it...

Just wish I knew the cause whether or not it was a bad build or human error issue. Hopefully LG or Tmobile dont charge me full price when they see the firmware has been tampered with. I could always format the system with nothing on it so it just sticks on the LG symbol and has no rom to load up i suppose lol
