battery problem solved?

Maybe this depends on the batterys but mine was having that problem of going dead at higher and higher % it started at 10 than 30 then 50 and up to 70 I think.
I've tested all the solutions in the wiki (yes the freezer too ) but with no improvements, then I did the opposite, instead of draining the battery fast I drained the battery slowly and when the Universal shuted off I pluged it to the electricity until it boots ok and the cpu returned to 0/1%, then take it from electric power again and wait until it goes dead again and did this over and over again until I reached the minimum battery of 9% i think. Great improvement since I was already looking for battery replacements... Then I charged it over night.
Conclusion I have the Universal alive for 3 consecutive days (and nights) now at 52% waiting to check when it dies again
By draining the battery slowly I mean no light in the screen, no running programs and universal in closed state, flight mode and just one thing to check if it was alive or not, play some music in WMP in repeat mode, when it stoped playing it was time to have a litte more eletric juice until I could boot it up and start the music playing again.
When I have the final results -> when the universal goes down I will post the solution in the wiki
Again this may depend on the batterys but since there are so many people buying new ones you maybe want to try this solution too.

Oh and by the way I solved an "other" problem while trying to solve this...
Besides the tests on the battery like freezing it over night, taking the power level pin etc, I've started to think it was a problem from the rom so I cleaned the Universal doing that "task 28" thing and the result was solving the problem that I was having with the battery status (now home screen plus plus) it was not getting the cpu using percentage when in the past it did. Now with the cleaning reg whatever It is showing again the cpu using %
I don't know if you use this but it has a cool functionality, posting the cpu using % at the top bar of your universal can tell you how much the universal is working all the time, enabling you to notice when it is working when it shouldn't, normally some stupid background program that didn't go off...

hi there. I have two same unis, and three batteries. two standard, one big capacity 3200mAh (personally I dont believe it have such capacity, it is some china crap). but all three had that issue (uni shut down when capacity still showing more as 30% or more %). tried to deplete the battery completely (when it wont boot, I put device to bootloader mode and wait untill died completelly). now it show again 0% on all three batteries. I dont want to say, that your method is bad . no, I am just a lucky one, where the "wiki" methods worked correctly. and I think it is also important sometime charge the battery completelly, not only for couple of minutes, but until you see green light. when you deplete the battery completelly to zero (it is never zero, electronics integrated on the batter doesnt allow that) charging to full take much more time as before.

powerdetect
one more thing, you can test, how much capacity your battery have. it is simple utility called power detect. you can find it in THIS thread or as attached file. just copy to device and run. the test will suspend itself after one hour, so set all settings as needed. it will automatically create file, where you can find all important information. before you use it first time, charge your battery to full.

Thank you for the reply, My battery still dies at 30% but no more at 70% and 50% and it lasts 3 days/nights in a row.
I tried the boot loader mode but it seemed it had a timeout, instead of dying from battery losse it died from some kind of time out :/ because I was still capable of juicing some more battery if i went again to boot loader...
I will check that app, thnks again

wat i did..
well my battery used to shut off at 95 above present...wat i did was drain the battery with a 12 volt motor, took me a complete day for it to discharge, then i put it in the freezer, was suppose to put it for one night but i actually forgot bout me putting the battery in the freezer n i remembered after 2 days. then i charged it which also took around 18 hours to charge now my batter shouts itself at 70% n i can listen to music for 1.5 hours. which is a lot from a battery which was shutting at 95%

[Q] Battery life with firefly 2.3

I am getting a very short life out of my battery. I run firefly 2.3 and with everything off i am at 50% after about 4 hours. any ideas please.
Samsung Captivate
Firefly 2.3
speedmod k13b-500hz #54

I'm not too sure.
I almost get 1% a little bit less than an hour 45~50 mins at idle.
This is no data and nothing on.
But once wifi is on, it ate about 15~20% in under 30 mins. This is with browser open and msn
I suppose data would be around the same if not a bit less or more underload.
I suggest do all those things that increase battery life ppl suggest on the stickies.

4 hours doesn't meant much without more info. You can have your phone on for 3 hours and been surfing the net or playing games the whole time so I'd expect your battery to be nearly drained.
How long is your phone on for?
What % is the display using up your battery?
How long has your screen been on?
After display what's next for battery usage?

I would go through all the basics:
- Charge to 100%, wipe back to stock and do a fresh install
- Charge the battery to full again, do all the basics to get a legitimate read (plug/replug, wipe battery stats)
- Check your about phone settings and look at battery use, check for battery hogs.
- Check to see if you are in an area with poor signal. I lose signal if I'm indoors where I'm at so I turn the phone to flight mode. If I don't it eats about 15% of my battery an hour.
I get consistently good battery life with my captivate/FF2.3, so I'm betting it comes down to a faulty install or battery measures.

I've also noticed this after I upgraded to 2.3 (from stock Rogers captivate). My battery used to be at maybe 70% at the end of the day, now it is at 20%.
I just checked it, and it is reporting 93% after 2 hours. The display has only been on for 2 minutes but has used 48% of the battery.
I have the display set to the lowest setting, no gps, no wireless, limited background apps.

ok i turned everything off and put into flight mode and set the screen to turn off after 15 seconds brightness set to the lowest point on the slider and starting out at 99% on my battery, after letting it sit for exactly one hour with no use at all i turned it back on and it was at 83%. how did it eat 16% doing nothing. I also did like you said with the reflashing and clearing of the battery info and still get the same results. do you think it may be a bad battery.

I'm getting great battery life with Firefly 2.4(no mods added) with WiFi on 24/7...might wanna upgrade, it is so easy with the on-board download and upgrade built in!

I made the mistake of flashing when I wasn't at 100% battery not knowing how much of a pain it was to calibrate the damn thing. I did however realize that after a couple of full charge/discharge cycles my battery life improved. FF 2.4 seems to have better battery life, but I haven't had it on the phone long enough to say for sure.

My first charge on 2.4 never displayed "FULL" in the top left like I'm used to seeing. I bump charged just once and cleared stats. Still couldn't get that "FULL" up there.
That said, my batt lasted 2 full days on the charge with minimal usage (3 or 4 calls, a few short youtube videos, 4 or 5 rounds of Angry Birds, otherwise with display off sitting by my chair on my wifi).
That seems like ridiculous good standby to me... perhaps too good. I'm afraid I might be badly overcharging my battery, so I let it drain until it I couldn't turn it on and it's back on the charger. I'm hoping I'll see a "FULL" up there this time. On the other hand, I sure could get used to that kind of standby time...

There is a Q&A thread in the Q&A forums please use those instead of opening a new one.

Those of you having battery meter issues - the ones that dont move

Seems I fixed mine. I had put an extended battery on this guy, and it would never change in battery level. I would have to reboot the phone to get it to register the new power level.
Discharge your phone to 0% until it shuts off. Try to turn the phone on several times to make sure its discharged (should shut off immediately). Charge the phone to 100% without unplugging it (will take a while, do it over night).
Today my % seems to be registering and no need to reboot the phone to change it. HTC tech support claimed they had nothing to do with the battery manufacturing so they wont help you.

if you reboot your phone how accurate is it to the actual battery meter showing you the percentage? I am at 6 percent left on my phone in hopes of discharging it and than charging it full to get mine to work

It will still probably jump down about 10% but it will sit there for a LONG time until the system is actually to that percent. My recommendation is dont reboot the phone if you want to keep accurate %. The rebooted value I dont believe indicates actual battery life remaining. There is a communication problem between the phone and the battery - HTC confirmed this is going to be patched (on the phone with them last night).

[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

[Q] For those who get 24+ hrs of battery usage

Battery drainage has been a major frustration for me with my phone. The frustration stems from the many variables associated with battery drainage. For the most part the terrible battery drainage started after flashing the modified ROMs. I believe the stock ROM was respectable when it came to battery drainage.
I am not ignorant to flashing ROMs. I have tried everything to figure out this battery problem; everything to keeping stock kernals, to battery calibration (delete battery stats), to battery bump charging, to matching radio files with RILs, to limiting data syncing, charge cycles etc.
But I am noticing that some of you are able to get good battery usage from a single charge with these modified ROMs. With that said, I want to cut the variables down and see what those folks who are getting over a day's worth of battery usage from a single charge are doing. The best indicator for battery usage to limit variables would be the battery usage standby rate with data network on.
I am not getting any better than 8%/hour on standby for any of these ROMs. That is crap. I wake up in the morning after 8 hours and there is only ~35% battery left. Unacceptable. I figure no more than 10% should be lost in 8 hours of standby.
So for those who have good battery usage, please answer the following questions so that we can eliminate all the variables.
1. What is your standby battery drainage rate?
2. What version phone do you have (TMoUS or EUR)?
3. Clockwork Recovery version?
4. What ROM are you using?
4. What Radio and RILs are you using?
5. How many charge cycles are you doing after the battery calibration and before you are getting the good standby rate?
6. Are you using any battery saving applications?
Please help if you can. Everyone seems to emphasize speed and performance but battery life is number one priority for any phone in my opinion.
Thanks

I'm currently running the P3D Neon ROM. I was having the same issues you are having due to flashing a new ROM jsut about every day. The big thing I noticed is that the longer I stayed with the one ROM the better my battery was. But as I'm sure you already know that no matter what a smartphone is a battery hog anyway.

By the way have you tried this, I am using it and love it !

I've had my phone a week and am using stock Rom. I've S-Off, Root and install backup. Overnite, the battery only goes down 5%
If I were u, I'd get Android Assistant from the Market and check that all apps are closed. Check ur start-up apps and clear ur cache before u shut down ur phone.

More than likely, there are apps that are not allowing the phone to sleep when the screen is off. CPUstats will show you how long your phone has been in deep sleep, as well as your CPU clock speed.
Here is what I would try out:
1-Get CPUstats.
2-Turn off the screen for the night
3-Check to see how long the phone was in deep sleep mode. It should have been for awhile if not, you have a rogue app that is bothering your phone while it sleeps.
To check your standby current:
So far, we cannot accurately see what it is. I dont know of any app that can for our phones. I do know that the values I see cannot be correct, otherwise my phone wouldnt be lasting long.
1-Write down your current battery capacity in mA/Hrs.
2-Write down the time that you put your phone into sleep.
3-Leave it off for an hour.
4-Wake it up and check the new battery capacity.
An Example:
I started with 1900mA/Hr.
I let it sleep for 1 hour.
I found that after an hour, I was down to 1850mA/Hr. That is 50mA gone, over 1 hour time. So my standby current was 50mA/Hrs.
Now this is only a crude way of judging whether or not your phone is behaving. Since the battery apps update capacity every 5 mins or so, you may not be right on the money, but you WILL know if something is BAD. Calculating 50mA +/- 20mA means the phone is likely sleeping as it should. Calculating 300mA+/- 20mA means something is USING your phone without your permission.
Youll need to find out if some apps are syncing (or trying to sync) while it sleeps. Or, your phone may be trying to improve your signal strength.

The anker battery will help but it is not solving the problem. We need to be getting around 1-2%/hour standby drain like some of you guys are getting.
