[Q] Disappointed with the battery life... :(

Hi folks - this is the first thread I have started, hence requesting the non-noobs to go easy on me... (this forum is a scary-kind-of-cool)
I mustered up the courage to install Infused 1.5.0 on my stock... the instructions were superb and everything went great... really enjoying the improved speed and looks. But my battery life has degraded. It has been more than a week since I flashed my phone - and it is only getting worse. Now I have read a lot about how Infused is getting great battery life for some folks... and i have gone through those threads, trying to figure out what I am doing wrong. This is my typical usage profile
1) I put the phone on charging before I go to sleep... when I wake up (around 7 AM) it is fully charged.
2) I quickly check overnight messages, finish the daily ablutions, and 30 min later when I check the phone it is already at 95%.
3) By 10 AM, I have made a few long phone calls (no bluetooth) (totalling 60-90 minutes) - and the battery is down to 75%
4) At work I use a bluetooth A2DP headset - maybe 30-40 min of calls and by 12 I am at 50%.
5) More calls in the afternoon, intermitted mail checking and sometimes 30-40 minutes of music streaming on my bluetooth headset - and by 6 PM my phone is down to critical level 12-15%.
This is in now way the same experience that others are having with the Infused ROM and with the Infuse phone in general.
Other points:
6) I run Juice Defender... (don't know if it helps)
7) My screen brightness is just a few notches over 0%
8) My data is always on - except when I am using Wifi of course
9) I turn bluetooth off when I am not using it
So that's the story guys... and I would eternally grateful if the awesome folks out here can help me figure out what I am doing wrong... or there is some logic behind the sad battery life of what is otherwise the best phone that I have ever owned.

It depends how long Infused has been running on your system. After about 3 days I noticed my phone was adjusting to the ROM and the battery life improved significantly. Aside from that, try this trick. Drain your battery next to nothing and then charge all the way. Do this a couple of times. Not quite sure about the logistics but it seems to work. Another thing that has improved my battery life is to make sure I don't have background apps running. You can check this by going into apps > manage apps > and then running. Sometimes Media Hub will begin a background process and that eats up a whopping 8 MBs alone. Force close these pointless background apps and you should see an improvement there as well.

have you conditioned the battery and reset battery stats?

Thanks popesmasseuse (you really aren't are you?)... the ROM has been running now for a week... gets worse rather than better. I do typically wait for my battery to drain completely before I charge it... but when I do have to do it at 7 PM - then I can never charge it fully, before I have to start using it again. I wonder if the fact that my phone goes through "micro charges" is a reason for my declining battery life...
Will check the running apps... and see if closing them improves things... thanks!

Fact: Installing a ROM greatly improves battery life... Try it....
Turn of GPS and Bluetooth when not in use.
Same here I uninstalled media hub... period... just useless...

Phone calls are a pretty heavy battery drain. Sounds like you're in call for hours each day. Most people don't talk on the phone more than a few minutes a day. Poor signal will also significantly reduce your battery life... how many bars you usually have at work?

My battery life got better the longer I had the infused ROM. But personally I only talk on the phone maybe a total of an hour each day, but I am constantly using internet and youtube, and if I have spare time I'm using my Kindle app to read some books. I keep my GPS, sync, and wifi on all day long and my brightness all the way up (I just can't stand a dim screen lol) and by the time I got home today my battery was at 40%, which I am perfectly fine with.

Ah...the man himself.
Yes I talk a lot on the phone - nature of the job. 3 hours minimum in a day. Signal at home is terrible - 15% strength... that could be the reason why the battery runs dry after the morning routine. Any way to offset that?
At work signal is great. But in office I also tend to use my desk phone more...

Err... no... Noob alert!!!
How does one do that?

http://forum.xda-developers.com/showpost.php?p=14912331&postcount=7
Read this post in another battery thread I am doing this right now to see how it performs afterwards.

Read the thread in my sig.
Never use task killers.
For me, battery life on phones gets good after about 2 weeks or so.
With light to medium use I can easily go for 2+ days.

Consider not streaming music through Bluetooth. Also don't auto sync stuff every 15 mins. If you can use Gmail they use Push notification. I'm on my phone all day literally and I make it home with some battery left. BTW connect to a Wi-Fi when ever possible, 3g data streaming will kill your battery quick.

has anyone tried this method?

It's a Lithium-Ion battery which means it does NOT respond to "conditioning".
"Reconditioning a battery involves completely discharging the energy from a battery then recharging the
battery. Li-Ion batteries do not require reconditioning to maintain good battery performance since Li-Ion
does not have a memory effect. It is necessary to complete drain and then recharge a Li-Ion battery in
order to determine its current capacity level, but that is not the same thing as reconditioning the battery. Li-
Ion batteries do not have a condition that needs to be reconditioned." lxe.com

Keiht's tutorial is effectively a technique called "bump charging" for putting that last extra percent or two of charge into a battery. However - with Li-Ion batteries, charging like this will SEVERELY reduce their charge cycle lifetime.
The only thing that "calibration" should affect is how your device reports battery charge level, NOT actual power usage. You should get the same total battery life whether your device is "calibrated" or not, with the exception possibly of the device shutting off prematurely because it thinks the battery is lower than it really is.

I would have to agree with you. I followed his directions as i was having horrible battery issues after going to 1.5.0 and it seems to have helped the reporting as far as I can tell. I think the big problem and it is only a guess is how the phone is reporting the battery condition not actual battery left. In any event I am running JD and the longer I run with 1.5.0 the battery seems to be lasting a lot longer but I have ti disable most everything which hobbles the phones best features to get that battery life still searching for the perfect solution.

[Q] Draining battery on first use?

Hi guys
I should be picking up my SGS2 today and I was just wondering what exactly I should be doing with the battery? I've read in a bunch of places that draining the battery fully and then recharging it fully gives better battery life, but I've also read this:
Lithium ion batteries do not respond well to full discharge, you will see reduced capacity and early failure if it happens too often. In any case it is not possible to overcharge the battery on a BlackBerry because the battery and phone have enough intelligence to control the charge (unless the battery is already defective).

(this is from crackberry.com but you get the idea)
What's the best thing to do?
And on Android phones, when the battery indicator shows 20% or something, is that when the phone is going to die? Or will it die at 0%? Obviously at 20% it would be to protect the battery but maybe Android has been programmed to show 0% when the battery is actually at 20%.
Thanks,
Elliott

read manuals !!!!!! You can see this

Did not receive an owners manual with my phone. Anyway...phone is charging now so too late I guess...

The manual is probably stored on the phone, at least my new Ascend II came with its stored on the phone, you have to goto the big menu (forgive me for not knowing the technical term for it) to find it however

i got my battery fully charged...then in the first day i discharged it till 10% at least that's what my phone was saying
i read too that the new li-ion batteryes do not need to be "formated" (fully discharged till the phone dies and then fully charged with the phone turned off) in android case i think that thing is not posible coz it needs at least 5% to pass the bootloader and then begin to charge
anyway in my manual it says that the battery will begin the normal state after 8 days of use, until then it may disschage quick
i have a motorola defy

Calibrate the battery. Charge the phone while its switched off for about 6 hours, and then use the phone untill the entire battery runs out and it switches off on its own. After this, the phone should be able to use the battery properly.

i just used my galaxy and made it empty, then charged it full.
nowadays i have runtimes from 3days (72 hours) and then its @ about 5%

there seems to be a lot of back-and-forth regarding whether or not draining a battery is healthy; i drain my iphone battery down to zero about once a month and the battery has been doing fine for two years . . . whether it would be doing just as well without the draining time is anyone's guess.

I have always been under the impression that lit-ion batteries do not need any kind of special care or break in. But since our phones estimate the charge, we should occasionally let the battery run out to reset the calibration in case it gets screwed up.

I don't think you need to worry about draining the battery till it's dead. My phone dies often and the battery is still kickin It's my understanding, that the purpose of draining the phone before you charge it is to calibrate what the OS says for charge remaining to the battery's actual charge.
Or something like that...

Hi all,
I have my sgs 2 since June and it's working pretty well apart from the battery drain which is very harmful in my daily life
I've recently flashed the Cognition 1.30 (last friday). Before that, my sgs was able to last the entire day before discharging with a moderate use (10-20 mn on games, few sms, 15 mn consulting mails, 1 hr on internet). Since i've flashed with the cognition Rom, the battery drain is really awesome!!!!!!
I fully charge the phone (switched off) then when i switch it on and the phone stays idle, after 1 hr or so, i've already lost almost 20%. When i'm on internet or playing games, the battery loss is approximatively of 1% per min.
I've made a full wipe and recalibrated my battery so normally it should at least last a day and thats not the case.
Could somebody help me or should i buy a new battery and test it ?
Because i relly like this rom and from others users, it has a good feedback concerning the battery use

Larger 3rd party battery problem...

I'm aware that not many of you are looking into specific threads in Accessories section so I'm putting my problem also here. I will be grateful for any help.
I bought 2x Chichitec batteries for Evo3D (this is probably the same Chichitec product as for Sensation).
I put in Chichitec battery (the phone showed about 59%), I discharged it till the phone switched off (noticed slightly better life than stock). Then I plug in charger and charged the phone for about 8 hours (much longer than charging to 100%). Then I unplugged, went to Recovery and deleted battery stats. Now the phone started to discharging much QUICKER than on stock battery! In about 14 hours of practically zero use, the battery went down to 8% and... it was on 8% for 7 hours! When the phone finally switched off I charged it again for 8 hours, unplugged and again, the battery life is very weak - 20% in 6 hours of idle (I was sleeping).
I haven't installed anything or turned on any setting, which could cause more draining.
Did I do something wrong? It appears that it has much worse life than stock battery and suddenly it works for several hours at the same % level... What can I do to make the phone show correct battery % level? Or is this Chichitec battery poor?

Anyone?
10char

could be a faulty battery... the resistance could be slightly less... there is a couple of things that arn't phone related however let it run for a few days and allow the stats to be built up again

Phone Idle & Call Standby = BATTERY DRAIN !

Running ExtremeSensationPrime ICS ( With Sense )
I tried every Rom but it still doest fix the problem
According to Setting > Battery
currently 62 % not charging
Screen 69 %
Cell standby 15 %
Phone Idle 13 %
Wifi 3 %
Mouse Lite 3 %
I did not even touch my phone after i let it charge till 100 % I took out the charger and place it beside my laptop while i play my games then every time Im
not doing anything the battery will decrease DRAMATICALLY ! please help it has been going on for 2 months already . I use Juice Defender and recently i just change my rom and it still goes on . HELP PLEASE

For what it's worth. Every ROM I've ever installed has terrible battery life until you do a battery calibration. If your rom has superuser, and pretty much any non stock does, charge it to 100%, 100% and then about 3 hours past that. Then download battery calibration from the Market and let it wipe batterystats or with it still plugged in reboot into recovery and wipe battery stats.
After that let it die down to 0. After it dies, start it up again. After that? Start it up one more time. Then charge to full again.
This should help. If it doesn't, you probably have an app that's abusing your phone. Grab currentwidget and track the battery drain in mA.

You should look for apps that abuse your system, usually those are apps that ask for a permission that prevents phone from sleeping. Look around your system and see if running app list has something unusual

I've used Prime for a couple of days and it has excellent battery life. I can actually do at least a 14h day on a single full charge, at least by how I use my phone.
The thing with it is, until you do a proper calibration you're not gonna get the expected longevity with any rom.
I suggest for you to follow the prior replies and then ask again afterwards

Check signal
Check also if the GSM signal is not too weak. Switch it to GSM only or WCDMA only and see if the battery life improves.

Battery percentage fluctuation

Hi everyone,
So i noticed that sometimes my battery percentage will drop 2% at a time for example, its 80% and then suddenly 78% ?
Also one time it increased 1%, i thought i might be imagining stuff however i verified it in the battery chart ?
That battery drainage seems good and am getting anywhere from 4.5 sot to 6+ sot(if the mra bug doesnt hit which it usually does)
* i noticed that sometimes if i turn off the wifi from the drop down quick shortcut, then i check the wifi from the main settings i will find its still ON ! Again i also verified it will stay on from the battery chart if i dont turn it off manually from the main settings, so beware.
Hopefully sony will do thier homework with android M

As far as I'm aware Battery percentage is a calculation depending on the status of your phone. So it's not 100% accurate and can fluctuate

This happened to me too! I left the battery runs out completely and so far has not happened again! I'm noticing that this android is sucking the battery very fast, as well as in the Z2 and Sony fixed. But I think that Sony will not correct this in order to be out a new android.

my xperia z2 battery percentage is fluctuating from 100% to 39% then again it rises to 70% plz help me out in solving this problem
