Last night I switched over to the EF02 Gingerbread leak and flashed the AA i3 rom.
I was loving it, but my battery went down about 15% in 20 minutes. Just while going through menus.
Browsed around a bit and found out about calibrating the battery, and how it can fix the issue.
So, my questions:
- Should I calibrate from a full charge?
- Is it a good idea to calibrate the battery every once in a while, just for the sake of it?
- What kind of battery life have some (any) of you seen out of the AA i3 rom with a properly calibrated battery?
Thanks in advance.

calibrating the battery is just a placebo effect in my opinion...i don't think it will help you at all
my personal experience with ef02 is it tanked my battery in 5 hours from 100% to dead
i'd recommend sticking with ec05 until we get a newer leak or official gb
go to market and look for battery calibrator and then i t will tell you directions from there
Could be ROM. My wifes epic is deodexed ef02 w ef02 modem and a few odds and ends and we are seeing 12hrs on a charge. When it was same ROM and ec05 modem...it made it 4.5 hrs w hardly any use and died.

That was kind of the suspicion I had...something sounds kind of off about "calibrating battery".
Even if the leak was making it 12 hours, I'd still have switched back to EC05 2.2 on SRF 1.2...which I already did. I'm very content with a reliable 20+ hrs.
Was fun to toy with though, definitely left an impression as far as things to look forward to. I'll keep waiting for a more stable/official...
Also, root explorer. Data/system/battery stats.bin. delete that file after full charge, meaning full charge, unplug, plug back in for 15ish mins. Reboot. Simple. You will be deleting the battery statistics manually and upon reboot it creates a new file. If you are paranoid about properly doing it that will do it.
Rodderik, nice to see that name more often again.

I just went back to SRF 1.2 to try it out might go back to EF02 Plus. No knock against SRF1.2 it is great ROM.
Make sure your phone is in deep sleep mode.

I am current running the Bonsai Rom 5.0.0.B12 and I am greating great battery life. Make sure there is nothing that is preventing your phone from going into deep sleep mode. Background data, also make sure that your cpu settings are on conservative. I use voltage control to change my cpu setting to conservative and noop and I use cpuspy to determine if my phone is going into deep sleep mode. If you do these thing you should get great battery life.
I'm not sure if I'm doing somthing wrong but I installed srf 1.2 with genocide kernel 2.0 and the battery life is just crap. I inplugged my phone and it was asleep for 5 hrs and it had 12 percent battery drain. When im actually using it, it dies fast. I've undervolted to -75uv on 1ghz have it set to conservative. At 100mhz its at -200, 400 -100. 600 -75, 800 -75. Am I doing something wrong?
You should ask this on the actual srf thread in development.
Two things you can do:
1. Battery Wipe. Search the forums on how to do this.
2. Give it a few days to recalibrate your battery to the new rom. My first 3-4 days on the SRF 1.2 and Genocide 2.0 were pretty pathetic. I got 6-8 hours of lite use. After the first few days of complete battery cycling (full charge to dead battery), I can get a full 16 or so hours of constant use. It's nothing great, but a lot better than stock.
If your phone doesn't sort itself out within a week of use, reflash the rom according to the instructions, doing a complete wipe of everything 3 times. The rom works great, you just have to give it time.
You can get an app called CPU Spy to verify that it is going into Deep Sleep and also Spare Parts and check the Partial Wake Lock to verify no rogue apps are running.
12% drain after 5 hours in deep sleep? Man...that doesn't sound bad to me at all. That's slightly over 2% an hour.
Agree with the guys about calibrating the battery though. Just remember, it will take a while for the battery to 're-learn' how to properly operate, so it will probably suck for the first few days or so.
I've read you should wipe battery stats each time flashing a kernel, but I don't believe I ever have.

That user cannot post in the development forum with having just 1 post. So they are in the proper location for their question.
Oh thanks, I didn't know that. Also is not charging to 100% normal? It maxes out at 98%.

I believe QBKing77 has a video on how to wipe the battery stats and calibrate; very helpful for those who haven't yet done it for themselves. (big shout out and thanks to QBK77 for the vids!)

Yes that is completely normal. It does this so the phone doesn't overcharge the battery, which would only harm it in the long run. (Or so I've read on here.)

This is about what I see as well. I always check screen off battery drain by charging to full before I crash for the night. Of course I calibrate first and give the battery 2 days to get conditioned to the new setup. CPU Spy is a great app to monitor how your phone is using the battery like stated above.

Make sure all your apps have syncing turned off unless you start the app. You will find that a lot of things end up on at first for no reason.

This. Especially facebook which seems to turn sync back on. Also pulse reader was a big one for me before I caught it. Besides that gmail should also be set to manual refresh only. Just use spare parts and look under network usage. These are the big ones. Also there are several apps for battery calibration. One more tip, remove those useless widgets! You don't really need them and they drain drain drain. with this set up I get a day and a few hours out of genocide and srf.

el29 has significantly increased battery life for me....
Your Android OS is exactly where is should be based on your display percent. If you actually turn your phone on in that time Android OS will start to drop and the display percent will start to move up...

It may be that your phone is not sleeping with the display off in some circumstances.
Probably all those background apps waking it up to check internet for updates.
You need to post your actual display on time also.
My battery life has suddenly dropped too since EL29. I updated and everything was great for a few days. One day I woke up and my battery was draining at about 10% an hour with no use. I've tried rebooting and it seemed to help a little but I'm still dropping at about 6% an hour where before update it was 3% an hour. No idea what's causing it and it was really odd how it came out of nowhere.
I asked somewhere in another thread for someone who had the skills to see if there was any major differences between EL26 and EL29 because I actually prefer EL26 but I figure they made 29 official for a reason

Stop using a nonsense app that does no good to your phone. Who in the world need anti-virus app for android. An't no hacker would spend time to come up with a virus that will steal your info. Some apps claim to do this and that but is just all BS. All you need is an app killer and that's it. If you have an app that is continue running ( other than the one require ) than of course is gonna drain the hell out of your battery and it will get hot.
I have a Seidio 3200 battery which was giving me almost 2 days of moderate use . Immediately, and I mean immediately, after the OTA my battery drain almost doubled according to my stats... I read XDA on the subject, and did a HARD factory reset witth DATA wipe.....no help. Thought maybe the battery was failing..so I ordered a 3800 Trexcell from EBAY. Then read the problem might be from a looping background app or a stuck radio....pulled the battery...waited 5 minutes...put te battery back and now I'm back to normal (if not better) battery drain....It might be that some of us who had OTA got a screwed-up install which affected background apps or radios, while some of us had a normal install...in either case... I'm happy to get my battery use back !

My Android OS usage is through the roof now, aka Android OS bug. I installed watchdog and it's the "suspend" and "events/0" processes running at 65-85% when the phone is supposed to be sleeping.
I have had this phone for 5 months without the Android OS bug. I installed EL29 on Feb 2nd. Everything was fantastic until Feb 5th then I suddenly noticed my battery draining faster than normal.
After spending about 3 hours reading up on the Android OS bug this morning I've come to the conclusion there is no remedy for this bug. Sadly Samsung has not fixed it and it's even happening to people with the Galaxy Nexus running ICS.

Same here. I am getting up to 24 hours with stock battery (syncing exchange as push, facebook and gmail), on strongsteve odexed blue rom.
It seemed like battery got better since the updates began (EK02, EL13) and then the battery drain got worse than ever with EL29. For comparison's sake I live in Chicago and work downtown during the day in a not so good cellphone environment for most of the day.
I reverted back to EL13 radio and Rogue's EL13 Repack Kernel, topped off with Calkulin's 2.8.1 ROM. Battery life seems to have returned back to normal, but Calk's ROM makes it that much better.
I plan on giving the battery removal trick a shot too tonight. Someone else on Rogue's or Calk's thread said that removing the battery after a full charge for 5 mins, then recharging again, made his battery back to normal if not better.
Here we go!!! My phone is almost complete!!!
It's not a bug...

I just installed ICS a couple days ago and have noticed a dramatic decrease in battery life. I was able to get a full day without charging on Gingerbread, ~15+hrs or so. Now on ICS I am maybe only getting half a day. After 5-6hrs, the phone is about ready to die with any use. I was hoping it would get better after a few days but it doesn't look like it.
I have attached a screenshot of my usage this morning. I talked on the phone for about 5-10mins, and played some games for maybe 10 mins or so, sent a few e-mails, and did some light browsing. All pretty normal use for me. Before I would still be at 80+% still, down into the 50's right now.
Whats gpsd and why is it using so much?
The gpsd is a GPS like service on your phone. Someone correct me if I'm wrong. Also, Did you calibrate your battery? That might help
Sent from my SPH-D710 using XDA App
Turn off gps until you really need to use it. It's a bug that keeps gps actively searching for a signal and that will drain your battery quick, as well as make your phone super hot.

Thanks guys, my phone has been super hot! I turned GPS off, we'll see what happens....
How do I calibrate my battery?
There's no need to calibrate your battery, I did notice yesterday that GPS was on even after I turned it off, but that was after using Google Tracker for a jog. I simply restarted my phone and it was fixed, lets not forget that this is still in early development. Although I will say that now on my third day with this rom, the battery is getting better by the day! Good luck and Happy Flashing.

Yep keep your GPS off and your battery will improve dramatically. When it works, it's a major battery drainer. We'll need to wait for a build further down the road for a fix.
The answer to your question essentially is, you don't. This phone has an auto-calibrating fuel gauge that makes previous methods of battery calibration (wiping battery stats or using the battery calibration app) useless.
For the one "possible" way to calibrate the battery on this phone, see this ...

But I don't think this is you issue. Turn off GPS for now and you'll be good to go.

how long have you had the ROM flashed? it may take couple of days to have it settled into the new system/software. give it couple of days with the same cycle of usuage/charging times.

I had the same problem but after a quick reboot it stopped, and even with the gps off the 3G/4G will still show location just no navigation.
Hell no BS i get 4 MAXXXXX hours with the fb17
On CM9 3.1 with Steady's FB15 Kernel and the FB15 modem I get about 1/3 to 1/2 of my previous battery life. The estimated mAh draw is also in that neighborhood.
From what I can tell it's mostly low level stuff that is causing the drain, stuff in the kernel and Trebuchet launcher. Exactly what I expect from early, un-optimized code. With time I fully expect that I will my old battery life if not better as developers get the time to work the bugs out.
I can't discount that some of my apps are partially incompatible with ICS and causing wonkiness as well. It also doesn't help that I enjoy ICS so much that I can't stop playing with it.
Leave ICS and get back on GB.
Ive had this phone since the day it came out. Switched to ICS once the developers started dropping ICS leaks, etc.
For the past 2 weeks for some reason, Ive had nothing but HORRIBLE and i mean HORRIBLE battery life. Phone would not last me more than 4-5 hours of heavy use. I'd have to carry around my portable battery pack to charge the phone on the go. I did everything to my knowledge to try and conserve battery life. CPU tweaks, battery monitoring, tried different ROMs, Kernels, Modems, etc, etc. Nothing would significantly improve battery life. I even went ahead and ordered a new battery last week to remedy this problem (which has not yet been delivered/used)
2 Days ago I flashed back to Blazer 4.0 ROM (GB).
I unplugged my phone yesterday morning at exactly 7:30am. Did not step back into my house until 530 which at that point I was at 35% and had been using my phone all day as I normally would. Web browsing, tons of texts, Used Navigation for about 2 hours, etc. I did not plug my phone to the charger until 10pm. Phone was on 19% then. Mind you, this is on the first day of the Phone being on a new ROM/GB so the battery has not yet settled/calibrated as Its only been charged Once since flashing over.
I refuse to switch back to ICS for the sole reason that battery levels have obviously improved with something as simple as switching back to GB.
Just a heads up for anyone with ICS on their E4GT having issues with battery life.
If only I got a dollar for all the times a thread like this is made.. I'd be rich. Blah blah ICS sucks yes we know... So far my phone must be a super phone because it's handling ICS well.

I agree with you, Ray. I'd also be rich for every time I've read of E4GT owners who's phones are running ICS with no problems. But then theres the bunch who also complain that they have problems. I never stated ICS sucks. At this point these phones are old by today's standards. Be glad you're one of the ones who's running ICS with no issues. I for one will stay on GB until I switch to a new carrier/new hardware sometime soon.
Just thought I'd give some feedback of my experience with battery issues on ICS in comparison to then switching back to GB.
I don't know if you've tried Blazers ICS ROM, but that thing has some AMAZING battery life. I've been running it for a few weeks now, everyday I get at least 12 hours of moderate to heavy use, without my own tweaks, and by the time I connect to charger I'm at 35%
Arguments apart
i have a few friends all on this or that ICS and none of them is happy with the backup
whatever its a fact ICS goodness never really reached E4GT, lets hope FI03 onwards some sense prevails at those losers at sammy and they push something which we can smile about.
FYI i am also on ICS Rom , still in testing phase after getting my new white beast 10 days back , already tried like 3 , each for three days
running galaxy 1.8 since yday and hoping it shapes well otherwise i ll also move back to GB
I've tried multiple ICS rooms and I've always gotten great battery life (14+ hours with 3+ hours screen on time).
The only times I've ever had battery life issues were when a certain app was the culprit and was keeping my phone from deep sleep or causing frequent wakes, which is almost always the case with poor battery life issues.
Check out an app called GSAM Battery.. it will tell you what is using up your battery in easy to read graphs and percentages. Also, check out CPU Spy to see if your phone is actually going to deep sleep mode when you turn your screen off--again, it shows you in an easy to read chart with times in each state.

Only the stock ICS rom is garbage with poor battery life and stupid stuff like grey text on black back ground. I have ran several custom ROMs and they all provided better battery life. As I have said before, I got 99 problems but battery life ain't one of them. You must be doing it wrong.

Still waiting for the new battery to arrive. I would love to try it but I'm in the midst of a heavy usage of Verizon PRL on my phone. Sprint doesn't like heavy roaming users from what I've been reading. Sprint 3G in my neighborhood here in NYC sucks Donkey nuts. I can cross the street and get 3 bars more than I have sitting on my front porch. But thats a whole other topic of discussion.
Im not sure why my phone couldnt play well with ICS but it really was horrible. I consider myself a heavy user and ICS couldnt keep up with battery demands. I tried undervolting, etc. Oh well. Been eyeing the SGS3 or the upcoming SGNote 2. Time will tell.
So far 3 days on Blazer 4.0. All my apps are restored via TB and no issues with battery like I had on ICS. Don't really know what else to say. :good:

I'm getting 24+ hours on standby time. I have gotten about 18 hours with about 3 hours of screen time. Facebook and GBA emus. I wasn't able to do this since GB. I have done this by doing one simple thing. Turning off data. I kid you not. Utilize that data toggle. I know at first you're thinking no I need data. But you don't. Unless you're some business person, then this excludes you. Wanna check Facebook?
Also, wii benefit from something else. 4G WiMax. You can turn that on even though your data is off. You still get decent battery life since 4GWiMx knows how to sleep. Also, if you're driving around, it'll pick up 4G eventually (unless you don't have it) and it'll download what it needs to download. So by time it turns loses signal, you'll have your emails. I tried this and I still got good battery life.
Using Battery Monitor Widget, I was able to see that my phone wasn't "sleeping". That's what the main problem was. That's why I wasn't able to find any rogue apps using Better Battery Stats. But I did see my phone stayed awake. Like once my phone died in 5 hours. 10 minutes screen time. 6 minutes of deep sleep. Really? That means my phone was awake for over 4 hours!? Doing what!? No app was at fault.
Extra stuff. No need to read if you felt you read enough
An app you all should check out...

Battery Monitor Widget (It's not just a widget. LoL!!)
It tells you how many #mA your phone is using. So if it shows 500mA. That means your phone is using 500mA per hour. Your phone has an 1800mA battery. So that means if your phone used a constant 500mA, it would die in 3.5 hours. This is a good way to see just how much power your apps are using, or if after 10 minutes your phone is actually sleeping. My phone actually started using 2mA. I haven't seen that since GB. I thought my phone would never sleep like that again. I cried.
P.S. If you get the app, in settings -> Calibration, change the battery amount from 1500mA to 1800mA. Apparently the app thinks our battery is 1500mA. Or maybe my battery REALLY IS 1500mA. I mean, it got my Nexus 7 battery correct. I didn't have to change it. I've always wondered why BMW said I had a 1500mA battery instead of 1800mA. I may have to look into. Wii all should probably look into that.
Also, those on Blazer ICS ROM. Using BMW, I was able to see something quite interesting. My phone would use a lot of energy. Like 1000mA just to send some text messages, or scroll through my app drawer. BUT, after I stopped using my phone for about 10 minutes, I'd turn it back on and BMW would show my phone gaining #mA, or charging. This means something is causing the phone to "drain", or show drainage, when there really isn't. The fact that the phone charges back means it never really used that much energy in the 1st place. But that only happens on this ROM. Since I figured out the data thing, I'm going to try CM9 again.
