What is up with the battery life on 2.3.3?

After replacing the battery with a 1600 mah Seidio battery. I still get bad results. For example, during lunch today my phone was at 50% in my locker. After 4 hours, I was at 21%. My Sync, GPS, BT and Wifi are all OFF.
How is this possible?
I use to own a Nexus One and in 4 hours it would go down 2% with CM6. Is Gingerbread an issue here or does my phone need RMA repair?

2.3.3 gives me better battery than 2.1 or 2.2

superaosp from [email protected] stock kernel or redstars depends but cm7 and stock OTA gave me better battery than 2.2/2.1

I'm running stock 2.3.3 and battery life is by far the best over various android versions.

2.3.3 has some weird bug where every once in a while the system gets into a weird drain state like it doesnt go into deep sleep correctly. i just got hit with this last night. it does happen all the time, most of the time on 2.3.3 battery life is excellent. i will lose 6% over 8 hours. but when that awake bug DOES kick in, battery drops like yours did.
you just have to reboot and check it again, the bug likely will clear itself and you wont see it again, for a while.

yes, this is exactly what the bug is. sometimes randomly on GB the phone stays awake for no reason, for hours. but when this DOESNT happen, batteyr life is superb. i only get hit with this bug once a week or less.

My N1 on 2.3.3 goes completely dead after 12hrs. I found the solution when doing a Google search. It's to go to Wifi Settings, Advanced, Wi-Fi sleep policy, and change it to Never. You'd think that would reduce battery life, but for some reason now my phone's battery life is very significantly improved. Now it's only down to about 30% after 19hrs when I put it on the charger.

It appears that 2.3.4 will address battery issues in Gingerbread.

That's pretty cool even though I've not had any major battery issues.
But improvements are always welcome
Here's a quote from your link:
"- Battery life: some users let us know that their batteries didn’t seem to be lasting as long; battery life should be improved for these folks. (Nexus One)"

I dont think its Gingerbread, ive used both stock and CM7 on my N1 and i was having good bat life on N1 stock gingerbread about 5-6 hours with heavy use, and with CM7 official rom i get 7-8 hours heavy use and up to 19 hours on days i barely use the phone, and on standby i can confirm 8 hours (while im asleep) it drains 6% by the time i wake up of course i do have it personalized and settings applied for bat savings.

I haven't encountered this bug with CM 7.0.3 (based on 2.3.3) but I found it very useful to let the phone just drain the battery completely once in a while (once in a few weeks) and than fully charge it.
After doing that, I can go through two days with regular usage of the device

I'm on CM 7.0.3, 2.3.3 and I'm only getting 13-15 hrs if I'm lucky. Wifi and bluetooth are off only syncing gmail and google contacts. I barely even touch my phone at work for 8 hrs and the battery life sucks.
Another weird thing is that once it gets to 15% left it just automatically dies and shuts down...very frustrating, I'm on the latest pershoot kernel too, the phone was given to me for free last month and it was originally purchased in Feb '10 so I just figure the battery is old and worn out.

No. Your battery is not aged, it just needs re-calibration.
One simple way is to re-calibrate your battery is to charge it when the phone is off or charge using a desktop charher, and you have to over-charge a bit - just leave the battery connecting to power source for an additional 1 hour or more, when the charging process has been completed.
This works every time for me.
Keep in mind that from time to time the battery may need to be re-calibrated again for peak performance.

I have this issue on Darky 10.1 (2.6 kernel), 2.3.3
Battery lasts around 10 hours with light to medium usage (its a new original Samsung battery as well).
Does anyone have any quick advice to fix this? Bit under time pressure due to job at the moment and don't have much time to research this. Any advice to fix this easily and quickly?

I had this problem after switching on the “Vorabruf über Mobilnetz“ in the Cache-Settings of Google Maps. Maps was closed, but battery was fast going down. Using XWJVH.

I too have almost the same problem with Darky Rom 10.1 - but I've heard that it has been fixed in the new beta version. I'm gonna flash it at the end of the week and after a few days of observing, I'm gonna tell you the results.

It's been through quite a few cycles.

I think I figured it out.....I think it was Skype. If you sign in the app is always on...it doesn't have an exit feature. There is, however, an app to close it. I used it and got normal battery life today!
We'll see if it keeps working like it should.

So I've upgraded to 2.3.4, (Ficeto.Deodexed.XXJVP) and Android OS battery drain stopped. Now it shows 70% battery usage on display (before it was 70% android OS). I recommend updating your system too

with darky on medium use never had more than 14 hrs )

I've given up for the moment and gone back to Darkys 9.5
Now at least I can get through one whole day and have about 40% left

Are you willing to flash the rom again? or you can try to use the speedmod 15g t11 for the kernel to replace the JVP kernel.

it's said that when you use the USB connection to your PC, you need to reboot it. So this battery drainage will not happen.
In the ROm 2.3.3 JV5 and JV6 for Asia, I do the same to keep the batter alive.

Try backing up everything and then factory reset phone. Generally this happens because of a few unwanted applications excessively using ur processor, in turn draining battery or there may be a malware that stealthily connects itself to the net. This will almost certainly cure the disease. If it doesn't, then there is a serious defect in ur hardware or some of ur system app required for properfunctioning of the phone is corrupted, causing excess pressure on the processor

It is a big problem to everyone, I charge twice per day for this.

Calibrate your battery
Let the battery go down to 0% and turn off
Then turn the phone on, it'll turn itself off again cause battery is low
Keep doing this until its totally 0%
Plug in the charger, charge it to 100%
Turn the phone on
Download SGS Tools from the android market place
Run the app
Go to "scripts"
click delete battery stats
Unplug charger & you're done
battery should be more stable now
go to settings
applications
running services
check what you have in the background
close them down if they're unecessary
I get through the workday with only 10% loss

If you have an really old SIM card, try and replace it with a brand new one. This may also help. I had bad battery run time with two LG Optimus 2x phones (about 10 hours) and not so stellar 20 hours with the i9000. Finally I stumbled over some advise to replace old SIM cards. Since mine was over 12 years old, I ordered a new one. It is not gonna change the world, I know, but it was worth a try .

Calibrating the battery in MIUI Rom.....

Hi all. I'm using Miui rom 1.6.17.1. i installed it without charging the phone fully and now my battery life sux :-\
So i turn my phone off and try to charge it for caibrating in CWM but it turning on once i plug the charger....
I understand thats it a known issue, so how can i do this thing?

calibrating in miui? i would say its impossible
when my charger is pluged in an i restartmy phone then spring the percentag from 40 to 55

sad ... same here ... but you may try to let your phone to complete discharging battery, until go off ... and after that charge it 100% without using the phone and clear battery statistics from cwm.

Well...may be it was stupid thing to do but i flashed froyo back on...calibrated and than flashed miui with 100%

well ... your battery will still suck...cuz its cm7 base..which has battery drain
cm7 <3

Yeah...thats a problem, but i'm in love in miui

The latest cm7 should have addressed it already.
I was in the same situation as you, battery only lasts 6hrs on any given day.
My battery now lasts more than a day even on moderate use n 3G on all day. I initially rest the battery stats then performed a full power cycle.
Now when I upgrade between miui versions, I always ensure that the battery is 100%

may i know how to calibrate battery ?
i m in miui rom

You can't calibrate the battery properly in MIUI as it is supposed to be done with the phone off, MIUI or rather as someone else has mentioned its down to CM7
It can't charge the phone with it switched off because I believe CM7 is based on the Nexus and the Nexus cannot charge with the phone off
I could be wrong though, but the above is what I have gathered through reading about it

Samusng Galaxy S2 horrible battery.

Hey guys, I recently got a Samsung Galaxy S2 (over 2 months ago)
At first it was really good with battery life, lasting over a day with medium use.
It started to get really bad, draining down from 100% to 50~ over night with no use at all.
I searched the problem and came across these forums, which said 2.3.3 was a problem sometimes.
Now this is also my first android phone, so I'm not sure exactly how to do all the tinkering around with it. Long story short, I found that changing to 2.3.4 helped a lot. It did, for 2 days, now I'm getting the same problem again. Maybe I didn't do it right? Need help! (also this forum is huge, not sure if I'm in the right spot)

Have you tried flashing a custom ROM and kernel? Pick out a ROM that you like and then install a nice kernel like Speedmod. Lite'Ning ROM v6.1 and Speedmod T39 together really increased my battery life.

Is there like a "how to" section on this site somewhere?
As I said, this is my first Android phone, so I'm a little lost as to how it all works

I "think" I rooted my phone and got a version of 2.3.5, which is also supposed to be better on the battery?

Or also get titanium backup, and freeze all the useless crap on the phone that you dont use. I did that and it went from 7% every hour (despite the fact that there were no wakelocks) down to 0.5% every hour
EDIT- on standby/very little use, that is.

Also after you flash charge your battery to 100percent and calibrate your battery there is a good free app in the market

Well if you're using its smart phone capabilities it will really drain quickly. Specially when on data. What I did was to get an extra variety and an external battery charger-best investment for this phone ever.

You can also see what drained your battery by going into battery usage: Menu - settings - about phone - battery usage. or create the shortcut on your desktop.

download betterbatterystats to check what processes are burning your battery and stuff. helped me a lot, this app.

Given that you are getting decent performance for a bit, which then drops off, I'd say it was far less likely that the cause was the hardware or the ROM and far more likely that it is something you are doing with the configuration or software.
Try removing any widgets you have added - does that improve battery life? If so, add them back one at a time until you find the culprit. Also, make sure you are not signed into stuff like Latitude - that is an absolute battery killer.
You have seen that you can get decent life from the battery, now you just need to work out what affects that.

It was the 2.3.4 OS draining the battery. I wouldn't touch my phone, and in 8 hours it went from 100% to 20%, with the status saying Android OS 100% in battery usage.
Now I'm on 2.3.5, battery is at 95% after 4 hours.
I'll give it a few days, and see exactly how it goes and if there is a substantial difference in battery life in relation to use.

I almost had the same problem with the battery but i flashed omega rom and so far i have no problems! I always have wifi on when i am at home and 3g when i am not at home and the phone can run up to 2 days!

Have you tried doing a basic search and looking at one of the 100's of other threads crapping on about battery life?

galaxy s2 i9100 Battery Problem!
I am using Samsung Galaxy s2 for a while and I am facing an extremely low Battery Back up. Around 9-10 hrs to the max. I got the battery changed from the Samsung service center and have tried changing alot of different firmwares.
KE4 -> KE7 -> KF3 -> KH3 -> KI3 -> Simple and clean 1.2 KI4.
Nothing works.
I am attaching my "Battery Usage" images along. Please find a solution for me. Thank you.

Calibrate your battery, but you must have root access. When you have root than load the calibrate app.

i am quite heavy users on my sgs2 at first i had battery problem lasting only 5 - 7 hours... i got juice defenders free version from market and well it didnt boost my battery life to 48+ but it did made me last 1 and half day

New battery stats!!
Alright I experimented with the battery to check whether there is a problem with my battery or my firmware/kernel.
I tried the same battery on 2 different Galaxy s2. Battery stats below :
DEVICE 1:
Firmware : Stock KF3 Rooted
Kernel : Stock KF3
Battery Usage : 14hrs
Display : 45mins
Voice Calls : 1hr50mins
Battery remaining: 50%
DEVICE 2:
Firmware : Simple & Clean v1.2
Kernel : SpeedMod k2-18 test3
Battery Usage : 12hrs
Display : 45mins
Voice Calls : 2hrs
Battery remaining: 19%
Now in the above case I have used the same 1650maH battery in 2 different handsets. So why so much difference in battery life on an almost similar usage when I also made sure that the Brightness levels of both the phones also remain same.
Please help me out on this.

LG GT540 battery drain very fast

I have LG GT540 with android 2.3.4 cyanogen and the battery is just getting drain to fast ( its new battery) .when i go to battery use i saids that android system use 99-100% of battery waht its not normal ( my friend has about 7-8% use) and she last for 1-1.5 hours with normal work ,in idle about 4 hours till battery drops dead. Phone is getting to hot , i tryed to put others 2.3.7 and its same again what sholud i do.
solution i tryed: wipe battery stats -didnt help
going from 2.3.4 to 2.3.7 -didn help
PM me to see pic cuz i am new here so i cant post outside links at the moment.

Did you wipe data when updating to 2.3.7? If not, try it (maybe also without restoring stuff from backup, if wiping+restore does not help)

yes i always wipe data/cache/dalvik cache so tahts not issue,can i format SD card is she a problem maybe?

yeah same for me i am also using a rather new battery

what worked for me
Hi
I wanted to thank for Zoe Rom on its thread, but i cant write on developer's threads yet (altough i clicked thanks button there).
Im glad i finally got rid of my memory hogging default rom and now i have a properly working phone again!
Also i wanted to reply there (to some people also complaining about battery endurance on GT540 on Zoe Rom) how i fixed my battery main problem.
Pic of current battery drain:
http://postimage.org/image/d8o8uusd7/
As you can see i am aproximatelly at 50% battery after 1day and 11h of not charging.
I had 2 problems:
1- Battery lasted aproximatelly 5 hours on standby (and i mean i wouldnt even touch the phone and the battery was gonne after that time)
2- During intense battery drain usage, the battery was reporting to have less energy than what it actually has.
1st problem solved by simply turning off the wireless after im done with using it. No idea how could that be taking away so much energy, but it was. Somewhere during the period i was using my default rom i got used to have wireless always on, and my battery on the later times was going away faster than normal (i also like to listen to music on the phone). At the time i didnt correlate the 2 things, and i just put in my head that it probably was the battery dieing on me. It wasnt! The wireless (i suppose because of the Sync function also being on) has been draining my battery like mad between charges.
2nd problem persists. As you can see on the pic, those 2 spikes down correspond 2 diferent aproximatelly 1 GB file wireless transfers with Wifi File Browser app. This transfers (PC->Phone) make the phone CPU have to unzip the two 1GB files to the SD, so they are very CPU and SD card read/write intensive (i can force this battery drops with other instense battery use like playing a 3D game for example). The thing is if during that temporarly drop on the battery level measurement, the level hits 5%, the phone will shutdown. But to be honest, this problem is minor comparing to the 1st one.
There is one other minor problem with my battery, wich is the reading being inconsistent (drops 10%, then gains 15% then drops 5% again etc), but is this a problem at all?
I read a post of a guy that had made extensive testing to his battery cycles, providing loads of graph of battery levels (cant find link) . I didnt read through all of it, but i remember the guy saying something in the end like "Dont be too paranoid with your battery levels, as they arent accurate. Instead use your phone normally and you will gain an idea of how long will it last with certain types of usage"
By the way, he also said for people to just charge their battery whenever they could/wanted as it has no negative impact on battery life. I also read a bit of a paper on lithium-ion batteries stating the same, so no more forcing full-discharges for me!
One last thing! Deleting the batterystats file is as simple as disconnecting your phone from the charger.Why? because that file serves solely the purpose of suplying the UI with info of the battery drain usage on the current battery cycle.
http://www.xda-developers.com/android/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
And you can confirm this if you unplug your phone while looking at yout battery stats.
I hope this helps
PS: pls notice that it could have been not the wireless itself that causes the battery drain, but some service using the wireless. Finding this would require more extensive testing.

Some people says that this does not work, but it worked for me. This procedure extended m battery life from 5h to 2 days..

Update
Hello again
I just wanted to give an update on the situation since i noticed this post is linked from the Zoe Rom thread.
Two days ago i bought a new battery, an unbranded one (cost me 15€ here in Portugal). The shop had a legit LG battery for 37.50€ but i tought it wasnt worth the money. This battery has the same specs as the original, except it is 1300mAh compared to the 1500mAh of the original.
I dont have any battery related problem any more. Yesterday i woke up (100% battery), unplugged the phone, let the wireless on all morning, listened to 2-3 hours worth of tunes, browsed the web a bit, tested some messaging apps etc. Today i woke up, didnt charge during the night, and im sitting on 45% battery. Wish i had gotten a new battery sooner lol
With my old battery the phone wouldnt shutdown. It would always automatically restart. I had no ideia a malfunctioning battery could cause this.

I've have had similar problems with the battery on my GT540 with all cyanogenmods - 2.3.7, 4.0.4, 4.1.2. There were no such problems with original 2.1 I think it is the price for the newer versions, I can live with that, I don't have to buy new phone
