why does your battery stats screen look different?

Oh and if I use the phone with light browsing/videos/music it can go for 5 maybe 6 days with the Gingerbread update and Mugen 4500 mAh extended battery. I got 3 days and was still at 68%.

To be completely honest, my battery life hasn't been very good lately. I'll take it off the charger at about 7AM in the morning. It'll be about nearly dead (in the orange or red) at about 6-8PM. Before the update, i'd get a lot more life out of it honestly. Whether I was using it or not.

i'm at 78% after 17hrs right now. but i utilize wifi.

had exact same experience. I've decided it's because while I'm on wifi at work, it's not a strong signal so the phone keeps dis/reconnecting.
I'd say that I generally get around 20 hours with normal weekday usage.

I installed xboarders tweaked with LG cam and nothing else and would get about 10hrs out of the battery. Then I installed the nontweaked version with all bloat and stock camera and when I put it on my charger I was at 30hrs with 28% left.

If you wanna feel good about yourself dl ZDbox ... it always seems to exaggerate my battery life...lol
With heavy use I get about 8 hours.

All the roms in this world... wont save you from yourself"

Since I installed this plain rooted rom my battery has flatlined. All I have installed on it is Beautiful Widgets and enabled wifi calling.
has anyone ever seen anything like this? 15hrs and it was still at 76%.....

My battery was horrible until yesterday. CM7 build 97 helps my battery a lot and then I also use SetCPU with a screen off profile and an in-call profile. Those 2 things left my battery at 7% after exactly 24hours off the charger and light to moderate usage.
Screen off - 312/216
In Call - 1000/216 with priority slider set higher that screen off profile.
Credit goes to 'phburks' for the profile settings.

Dude you didnt even use the phone until the end where it dipped.

Yeah, isn't that what your looking for? I only want my battery to drop when in use. Every other rom I have tried the that slope has been at around a 45° angle.

I'm guessing miui

Longest I've had mine last was about 13 hours
Sent from my LG-P999 using XDA App

8-9 hours
I've gotten better battery performance on Eagleblood 2.3.5 ver1.6
Overall, still sucks. I've not tested the battery because I accept that having android, I can't expect for more than a day's use. My nokia e72 has great battery performance.
I'll push to see how much I can get, but honestly, I accept it. I'm always near a charger so it doesn't matter. Spent most of my frustration on getting a working ROM with my phone.
Now I can tweak with battery performance. I don't expect anything more than 8 hours. I use my phone alot.

last full charge on my G2x with Faux's rom and UV kernal lasted me 55 hours with normal usage, H+ (3g+) most the time, the true 42mb 4g isnt out here yet

I got 12 hours today. Amazing.

What do you guys think

I think your last image got messed up. The three visible look identical (no drain).

I think what he's trying to point out is at 4 and a half minutes he's still at 100%, at 9 minutes he's down to 99%, at 13 minutes he's down to 98%, at 35 minutes he's down to 95% - and I think he's saying he expects his battery to be a lot better than this.
If you're checking your battery drain that often, I expect your screen was on a good percentage of that time, and yes, Display will use a good % of your battery. Look at your Battery Use, what's eating the most battery?

Oh, I wasn't looking at the battery icon. And now the other image shows up. I thought maybe that last one showed a huge drop. That would have indicated a bad battery.
homeslice976 is right. If you keep looking at it, it'll keep draining fast. Get a widget from the market that keeps track over several hours (or days) and look for trends there.

My problem is this, i leave my phone charge over night and when i get up in the morning i disconnect my charger.
but as soon as i disconnect my charger no more then 1 to 2 minutes i already lost 1% within 1 to 2 minutes of disconnecting the charger yes i understand if i keep checking it it will lose battery.
but as soon as i disconnect my charger i light up a cigarette and then go to my text messages, like i said 1 minute still smoking my cigarette it is already at 99% before i even open my text messages
this battery sucks big time, i had a MT4G and i have way better battery then this
Speaking of MT4G i am going to put it up for sale in the Sales section.
have a bunch of extras for it

You might try battery monitor widget pro from the market. It will give you a nice graph of battery usage over time.

You also seem to have an inconsistent signal. By the third screen, you were down to EDGE. If the radio is constantly trying to get you a better signal, battery life suffers.

This is true too. Play around with different radio/ril combinations, letting them settle in for a day or two before testing and see if you get any better results

Well moved from LeDroid to Virtuous Unity and battery looks a whole lot better and so does my wifi signal.
I have installed the Battery Monitor Widget so we will see what kind of results i get with it.
PS i am also using a Slim Extended Battery from Anker 1600mAh
had one with my MT4G with 1700mAh and it ran great

Your screen takes a lot out of the battery, end of story, not much you can do. I agree the battery life you originally posted was nutty. I had the same thing when I first starting using Coredroid. These links helped me knock out some of the other high battery drain issues and since haven't had too many problems..I do these anytime I flash a new rom and battery life has not been an issue. Hope everything on the new rom works out man!

I am still scratching my head. What is so wrong with the pics above? I don't dee it. Everything looks normal. Last pic shows 95% and awake time of 21:43. Do the math and that is over 400 minutes of wake time on a battery charge. Not to mention that you were doing something on your phone as you did switch wifi on for the last 20 minutes between pics.
You can't measure your gas mileage in a car by only driving 30 miles nor can you on your phone in only 30 minutes on a battery that probably isn't perfectly calibrated for the phone anyways.

Addtional battery Management on Custom ROMS

I realize this may be sacrilege to some, but is there any advantage to installing a battery management app like Juicedefender to a custom ROM? Or is each ROM optimized enough to not need third party apps like this... I just installed the ICS 2.3.5...
If not, are there custom kernels that can be flashed to this ROM to optimize battery more?
Thanks.

Actually, there is EVERY advantage of installing JD on any rom. JD does things no roms can do, like enable/disable connectivity such as wifi, gps, bluetooth depending on variable you chose such as location, time of day....
I use JD ultimate and this is what i usually get...JD is probably the best battery manager out there, you can couple it wil SetCPU to additionally tweak it.
On this screen is my usage for tha past day, i have 25% left and i've already have 26 hours on my battery. JD is set to keep wifi on at all time when im home. Imagine how much more i could gain if it only enabled wifi every half hour to sync my stuff.
Also take into consideration i've been uploading all my pictures to dropbox for the past 1.5 hours. When i woke up 2 hours ago, i have 43% remaining. So dropbox drained 20% in 1.5 hours

Very nice thanks, good to know at least I picked a good one...
Also what battery app is that u r using?

battery status

I don't see a point really. My screen uses most of the battery.
Sent from my SAMSUNG-SGH-I727 using xda premium

I dont understand how you can "not see the point". Even a save of 10%-15% gives you at least a couple more hours of up time...we all know there is no magical solution for such a hungry, battery guzzling phone, but why not make the best out of it and control what we can?

I guess I do see the point. Maybe I just don't care that much. It makes sense to try to maximize battery life, so maybe I will try it out. I don't care much for the idea of turning off data when the screen is off with manual sync times though.

buy a extra battery. or a car charger. juice defender and under volting will help but not much. just turn screen down your self and turn wifi off which leave house. i tried most bat apps there are. i don't use any now and get better life then most people. been work eight hours and I'm at eighty four percent still. that's with use lol. jd uses more then it saves

Any of you guys try that double capacity battery, if it really does give 100% more juice? I am debating over it because it also makes the phone heavier and almost twice as thick... the slim form factor and weight is one of my fav parts of this phone so..

There's a double capacity battery? Where can I get it?

I'm sure they sell it elsewhere but it is all over ebay and I was tempted:
3800mAh Extended Battery + Cover
I love my slim form so I may just get like a battery 3 pack and always keep a couple charged in the fridge or something... when I go out for a while it can easily fit in a back pocket or bag for emergency.

Phone powers off when using camera flash

If I use the camera and have the flash on, and the battery is less than about 75% charged, the phone shuts off and won't turn back on until I pull the battery.
Often, when the phone powers back up after this, it shows the battery is almost dead, or at least significantly lower than before - I've seen it go from 70% to 15% a few times after this. It's done this with every ROM I've had, including stock Gingerbread and ICS, but it used to only do it if the battery was close to dead. Now I pretty much can't use the flash unless it's fresh off the charger or plugged in.
I'm thinking the battery is shot, would I be correct in this assumption? If so, can I use any Nexus S battery, or do I need to use a 4G specific battery? It's the Sprint 4G model.
Thanks!

If anyone cares, I got a new battery. Camera now works reliably, and I now get more than 6-8 hours out of a charge. Snagged the Anker 1600 mAh battery from Amazon.

While I was out today (about 3 hours), 4G was on, and I had music streaming as well. Running JellyBean (CM10 Experimental) with Air Kernel @ 1.2 GHz.
Think it's safe to say my battery was shot - it was a Sprint-branded battery that came with the phone, but I got it used, and the person I got it from last year got it as a refurb.

When was the last time u reset battery stats in the old battery since its supposed to be done at least every time u flash a new ROM or if in same ROM for some time do it about once each month....
And what ROM where u using and what camera ..... stock or market APP?

One of the Google developers came out awhile back and stated there's no reason to reset battery stats, ever. TWRP 2.2 doesn't even have the option anymore. Plus the phone kept powering off when I'd use the flash on the old battery.
I'm using Burns' CM10 Experimental (8/6) with Air Kernel, but I've had this issue with every rom, including stock (as stated in the OP). Problem happened with stock camera app and every 3rd party camera app, also happened if I used the LED as a flashlight. When it's happening across multiple ROMs, I think it's a safe bet to say it's a hardware problem.

..

The phone was a refurb that I bought used, and came with a Sprint-branded battery when I bought it. But yeah, I was basically asking someone to verify what I was thinking - which you just did.
Here's the battery it came with:
Anyway, several days on the Anker battery now, and no complaints at all. Battery life is easily tripled, though this screenshot was taken with me sitting on wifi all day. It seems to hit 70-80% about when the old battery would die. Remember I'm running an early experimental build of CM10, with a mild overclock.

[Q] Help with identifying Nexus S i9020a Battery Drain

Running Stock ICS 4.1.2 on Nexus S i9020A on AT&T US.
The battery was fine till about a few months back, but of late, it is draining @ around 8-10% per hour on standby!. I originally thought JB was causing the drain, and switched to ICS, and finally to GB. But the drain is consistent across all three.
There is also accelerated battery drain if my phone is completely switched off. If I leave the battery in the phone after powering off, the battery goes from 100 - 0 in less than 4 hours. Thinking the battery might have gone bad, I bought another oem battery, but that is exhibiting the same behavior.
This leads me to think there might be a hardware issue with my phone. I am tired of keeping the phone plugged in at all times, and am ready to throw this out the window and get another phone. As a last ditch effort, I wanted to post this here to see if I can get any kind of feedback/confirmation on this before I buy another phone. Other users are reporting 1-2% battery drain on standby, so 8-10% drain is unacceptable by any standard.
I have attached some screenshots from today when the battery was at 20% after about 9 hours. For this test, I did the following last night:
1. uninstalled all apps I downloaded
2. turned off WiFi, Bluetooth, GPS, sync, auto brightness ( set to the minimum brightness)
I charged the phone fully, and then left it on standby, with minimal usage - I think I made a 2 minute call, checked my email once, and read some rss feeds for about 5 minutes in the 9 hours I tested it.

Any help would be much appreciated.
Thanks!

I know I'm not giving any advice here but I just wanted to let you know I'm in the same boat. No matter what ROM GB/ICS/JB I lose too much battery per hour with the phone just on standby. There's no explanation for %10 battery drain per hour with pretty much everything off (wifi, data, gps, nfc, background data, etc)
I have tried everything and now I must admit I've given up. I'm just going to ride out CM 10.1 until I can decide on a new phone, most likely the Nexus 4 or HTC One.

Bro, just replace the battery, buy a new one!

Doesn't seem like a software issue to me, sadly.

That confirms my suspicion. I guess it is time to start looking for a new phone. Thanks!

Yeah, your phone doesn't seem to be doing much while asleep. 20 minutes screen on, 35 minutes active, yet battery down to 21%. My battery would be at 90% with that sort of usage. Since you changed the battery (I'll assume it's a decent quality battery, although a cheap battery could be in cause), there's not much left.

Have you tried switching 3G off? 3G seems to SUCK the life out of these Nexus S batteries like no tomorrow.
But I suspect it's a hardware issue with the Nexus S phones. I have WiFi, Bluetooth, 3G and auto-sync all shut off and a static wallpaper and I will lose 20% of my battery in 7-8 hours.

Battery is kernel related. Try changing your I/o scheduler to row and governor to smartassv2. If you don't have those options then look for a kernel that does...air kernel and matrix should suffice.

NO SOLUTION so far
A friend was having the same issue, gave him the battery of my nexus s ... it lasted him for 7-8hrs max whereas it gives me 1 day~ on 2G and normal use without gaimng . So my guess like his mobile your mobile may have some component which is short and draining out the battery . I have been trying to look around for answer but so far no luck. So better check it with another batteryif you can before purchasing a new one.

Vampire test
If anyone is investigating why their Nexus S suddenly starts draining the battery in a matter of hours, BEFORE spending a ton of time (like I did) trying to diagnose what software problem you might have, do the vampire test, as described here:
http://forum.xda-developers.com/showthread.php?p=42586314
I wasted days before coming across this test on this forum, and it proved it had to be a hardware fault.
I have two healthy batteries, both hold a charge for days (probably weeks) when not inserted in the phone, but pop one in the phone, leave it powered off, and within 6 hrs it's dead. So frustrating, and sad to see this phone go.
