I followed directions on what I thought to be a battery fix, but it ended up making my battery life twice as bad. Actually it takes longer to charge now than it does to drain.
Anyone else have this happen?

I did the same thing, but I've only charged once and I didn't time it. I haven't been timing any of my charges or discharges, but maybe give it some more time, that's kind of how stats work isn't it....usage over time? Good luck.
Today I started at 100% (not a powered off full charge though). After 2 hours of moderate use I was down to 50%. I have been charging for an hour via car charger and currently at 67%.

Not to be a dink, but then it would appear that you didn't follow the instructions. As a result, YMMV I guess.
1. You will need to charge the phone to 100% (while the phone is off).
2. Leave charging cable plugged in.
3. Boot into recovery and wipe the battery stats (should be under Advanced).
4. Then boot into Android.
5. Then remove the charging cable.

Give it another shot, and I would suggest that maybe it not be thought of as a "fix". Try using the wall charger as well. I only use the wall charger as I have a converter in my vehicles. Let us know how it goes!

Those are actually the directions that I followed yesterday afternoon. I didn't notice the battery life being any different after doing that initially. At the end of the day I charged my phone via wall charger for roughly 8 hours while I slept.
I was unplugged for less than two hours and watched it drop down 50%. Wifi was off, Gps also off. I was doing some web browsing and also using the xda app. I played a game for a couple of minutes.. That was it. I really should've checked the battery usage but I didn't think of it in time.
I only charged it in the car today out of necessity because of the super quick discharge. When I'm at home I only charge with the wall charger.

I'd venture a guess that you have something else running the background. I honestly wish that I had something more for you, but I'm going to have to fold.

I've heard others say they found facebook or twitter running in the background and that when they killed that it made a big difference in battery life. Perhaps that?
WiFi set to never turn off
I noticed this morning that WiFi had been set to never sleep, I just changed that t 15 min.
Had a full 100% charge last night did not leave on the charger, minimal use this morning down to 78%.
Let's see how the new WiFi settings works.

that doesn't do anything unless you leave wifi on all the time, and if you do then that would be one solution to this problem.

I experienced the exact same issue after doing the battery thing yesterday. Tried several different kernals since then - no change: I could just about watch the battery go down. This morning I wiped and loaded SR Sense 2.5.2 and the updated stock kernal from ROM manager. We'll see how it goes...

I did this and just installed 2.5.2. I then installed the Hydra kernel and wiped battery stats when I was at 100% and the unit was off/green light. The battery has gone to crap too. Any ideas?
thats weird, i did wipe battery stats (correctly) at 11 last night. i woke up at 9:30 (lol) with 93% battery left. the phone was sleeping the whole time, but i had sync turned on and had recieved several facebook updates, txts, and emails. now im losing around 10%battery every two hours or so, and i am using the phone to send txts and emails every three to five minutes. so battery life is actually much better. after the cable is unplugged, is it necessary to let the battery die fully, then charge, or can i charge it now? (its at around 30%)
so basically, i was wondering if it is necessary to run your battery fully down after doing a wipe battery stats
I don't know what to tell you guys. Since wiping stats, my phone has been up for 36 consecutive hours with an awake time of 2:40 and the battery is at 30%.
For reference I guess....

Great question. Anyone have any knowledge on this? I didn't let mine discharge all the way.
I do have some kind of update. I had to do a factory wipe today and since I did that my battery life has been much better.

I was about to do this but now I am skeered.
It's completely impossible for wiping your battery stats to make your battery life worse. It's a common misconception that by wiping your battery stats you somehow condition your battery. It's actually quite the opposite, because you're actually conditioning Android by wiping your stats. No matter what your battery percentage or meter says, your battery is still capable of holding a certain amount of electrical charge and your phone will not die until it's fully discharged. On the other hand it *might* make your percentage or battery meter read wrong if you either:
a. wiped your battery stats without a full bump charge (e.g. wiping your stats at 60% charge *might* make your phone think 60%=100% and as a result, you'd see huge decreases. but, you would most likely sit there with a phone showing a 1% charge for hours after it got there.)
b: didn't allow your phone to discharge fully after wiping your stats (same problem as example a, but the inverse of it)
All wiping your battery stats does is delete the file "batterystats.bin" from your /data/system folder. This file is recreated when you boot your phone after wiping them. It keeps the data on what's using your battery for when you click "battery use" in the settings menu. It's also thought to hold the stats that tell you phone what a full charge and no charge feels like and that if you fully bump charge your phone, wipe that battery stats, and then full discharge your phone (without interrupting it by switching ROMs or doing updates) that you will have a more accurate battery meter. It won't eliminate the need to bump charge your phone or make your battery life better. It will just be perceived as better since you won't get 20% drops in your reading in 30 minutes due to a badly calibrated batterystats.bin file. Also, you'll feel better because instead of looking at a 50% reading, you'll be looking at 60%.
Your battery still has the same capacity, charges to the same level, and discharges in the same amount of time. The only thing that can change those things are usage levels.
so should i redo my wipe battery stats then? when i originally did it, i ran it down to around 40%, then rebooted, then i plugged it in around 15%. would this mess it up then?

Do you know how we can see what's inside the actual batterystats.bin file? I tried in root explorer and cannot open in no matter how I try.
i dont care what vantagejuan says, when i tried this process...and did it correctly, my battery was down to 85% within an hour..i know this because i unplugged it when i woke up for work, and i when i clocked in, it was at 85%
it was never this bad, i tried locating the file again from an old backup, but it didnt help...im hoping that like someone else said, a couple cycles through it will get better
im using the skyraider 2.5.2 vanilla with the hydra oc/uv kernal
i had this setup before AND after trying the battery fix and im using the seidio 1750...
frustrations are back from when i first got the phone
After successfully booting into android for the first time my battery life in android skyrocketed down, but that didn't really bother me.
The real problem is that even in WINMO my battery life is less than half what it used to be, and even after a night (8 hours) of charging (In a wall socket, not USB) its not at 100%
this has me very worried, any ideas? thanks in advance!
did you read anything before you started this thread...........
yes, i did. everyone is having a problem when they charge in android it gets to 90% then they switch to winmo and within minutes it picks back up to 100%.
this is not the case for me, my battery does not jump back up, it drains quickly even in winmo, and when it gets low its not just reading it improperly it just dies, so no this is not the same problem
did you know there are fixes .......and that your problem is not new at all....i am sorry to say that this is a know problem and you would want to ask in the thread of what build you are using and if you really wanted help you would post what build your using and what kernal , but no one can help you at all when you simply state you have battery issues
drain your battery in winmo till it dies, so the battery resets, then charge the battery again till full, it should be allright again.
thank you dipdap i will try that

I strongly advise you NOT to do so. Draining a Lithium-Ion battery entirely is detrimental to its overall life/capacity. So instead of ruining your battery (or going a step towards ruining it), simply turn off your phone, charge it until you get the green LED, boot back to WinMo and it should be alright. If it isn't, look for another way, but completely draining your battery should not be the method of choice.
nobody said to drain it copletely, just till winmo dies, which should be fine. I do this once every couple of months by accident, and have never had a problem. I agree that you should not drain the battery completely though, so, make sure as soon as winmo dies, plug in to a charger.
what rom are you running? I am using shubcraft 1.5 and mine charges to 99% And I can get a full day out of my battery with pretty decent use.
Are you using setcpu cause that could have a major impact also do you have wifi,gps or bt on. I know gps has been known to cause some major drain while in sleep mode.
There is also a thread where people are trying to find solutions to the high amount of drain in the development forum.
We use current widget to create a log and monitor Our drain. You should be seeing less than 10ma while sleep I usually see between 3-7ma while sleep
Funny how when you are watching your battery it drains faster. When you are watching the clock time goes slower.

It was very helpful for me to identify how much current is being used while in sleep mode and active.
Download "current widget" from market and monitor your current supply for 30 minutes during your phone's screen is off.
Yeah with the screen off you cant see any thing but thankfully the log will be written for the current widget every min.
If your current comes out to be bellow 10ma during this time then you are doing good and should last you one day of usage else you need to pinpoint what is drinking all the juice even while your phone sleeps
Read the thread ALL OF IT, it will help you understand better.
Cheers.
alright thanks for all the help guys, the battery drain actually worked although i felt strange doing it, but still my android life isn't so great, i would love for it to work completely though because the only wquivalent option on my carrier is the Captivate (Galaxy S) and that thing is ugly compared to the HD2
such problem
I have such problem with battery drain under WM, after i run and quit android, but i found a solution, just pull out your battery few times next just recharge it and it will be OK .
After much googling this is the way that seems to be best when recalibrating battery. I just see so many people with poor battery life and it's likely because you've flashed new kernels and roms 50 times a week =p
Minor update! I recalibrate my phone today and realized something, this is reflected in a few new steps.
Step 1: Charge phone to 100%
Step 2: Wipe battery stats and shut phone off.
Step 3: UNPLUG PHONE and power on
Step 4: Leave phone on until it it shuts itself off. Do not plug it in.
Step 5: Turn phone back on, still unplugged. If it can't turn on that's fine. If it can turn on let it fully drain again.
Step 6: LEAVE PHONE OFF. Plug the phone in and let it FULLY charge without interruption. I let my phone hit the green light and then wait an hour before step 7. Some people suggest waiting 3 hours, some people suggest longer.
Step 7: After it's hit green and you've waiting a while unplug your phone. Do not turn it on. Wait a minute and then plug it back in. If the light stays amber for more than a few seconds (like 10 tops) leave it charging again until it's green.
Step 8: Repeat step 7 until the light turns green very soon after you plug it back in.
Step 9: Unplug and turn your phone on. Enjoy your (hopefully) extended battery.
I also suggest using "Juiceplotter" widget. It "records" your phones battery usage and uses it to predict future battery life. It won't work perfectly for the first day or so but after it gets used to your habits it's very good at predicting.

I haven't tried that out. Going to try to and I'll post results.
Thanks dude, I guess this will work with calibrating a new battery too? Just got the 3500 battery and was wondering exactly how to calibrate it for the first time...
Yes and I suggest recalibrating if you
a) Have a new battery of any kind
b) Have a new eris but the same battery
c) Flash a new kernel
d) Have been flashing many new roms
I find it' s a good habit to only flash roms when you're battery is at 100% to prevent your phone from getting too confused.
I read that after 5-6 full discharges of the Seidio 3500 battery that your battery life will improve... But I also heard that full discharging and then charging isn't as great for your battery... so what should I exactly do? I've already discharged and fully charged it once.
HM, you should also start a thread about "Tweaks I've found useful, and how to do them" and share your findings with everyone. I think that would be very helpful to noobs and the less-than-technical types that would like to get more out of their Eris'.
I know that's alot of work, but I'm sure lots of people would help answer questions when you're not available.
And you can add stuff as you go, wip type page Just a thought, cheers!
I'll consider that, I just feel like I don't have all that much to contribute that others haven't already lol but we'll see.

Your eris's battery will never discharge completely, it turns itself off WELL before that point. You don't have to worry about hurting your battery in this day and age, maybe 10 years ago.
If you've discharged and fully charged once it might be recalibrated. Are you still having battery problems?

This is one way to calibrate it but if you've been flashing roms/kernels just going to "100%" isn't enough because your phone doesn't know what 100% is. I'm sure that way works well when there isn't a huge problem but for some people their batteries are way out of whack.
How about having 2 battery?
Right now i have 2 battery and switch one of them when other runout of power.
Should i calibrate both of them?
Is my way to switch battery is wise?
Thx
Sent from my using XDA APPS
Don't switch between a 30% battery and a 100% battery, try to keep them around the same percentage. I can't say for sure because I don't know how the phone deals with that..
I tried this method yesterday (charged to 100%) , then last night and this morning drained the battery till dead and then charged to 1 hour after LED turned green. After I re-started my phone I was getting 1 % battery drop almost every 30 seconds, or every time I touched the phone it would drop a percentage point. :yikes:
So, I incorporated the "other" method mentioned here and turned my phone off (at 90%), plugged the charger back in and let it charge about 30 minutes after the LED turned green. I then booted the phone into recovery (while still plugged into the charger) and wiped battery stats, rebooted, and then unplugged the charger.
After this, I left it on for about 10 minutes with 3G and Sync active and only got 1% drop.
Kinda thinking this may be the ticket, for my phone at least.
Thanks for posting this up, I'll keep an eye on things and see if I can notice a difference. I was getting pretty decent battery life prior to this, but I agree that things need to be cleaned out sometimes after all these flashes.
I'm going to wipe GPS this afternoon and re-set it. Too much fun!
Yeah I did this method, wiped stats at 100% let die completely, charged all night turned it on and only had ninety percent and falling without using it.

I've gotten to 66% while on a lengthy phone conversation with my Gameboy emulator in the background, and then some gameboy (fully overclocked) for another hour at least.
I suggest using "JuicePlotter" widget for monitoring battery. After a few days it becomes very accurate.
I'll check out juice.
No setcpu. Just stock 710Mhz. Conap's CFS kernel is light on the battery.
Also, I play around with the auto bright settings to use the minimal needed for various lighting environments.

I see a lot of people not using SetCPU anymore. I like using it to underclock while the phone is not being used. If the kernel is 710Mhz stock now, would I just set SetCPU to 528Mhz for normal use or would that override the kernel?
Hi guys,
I'd gladly post this on the CM7 RC's thread over at the dev forum but I have yet to accumulate 10 posts.
Lately I've been experiencing weird battery % issues in CM7RC2 and now CM7RC4, that the charging would be stuck at a certain percentage even if I charged it overnight. It never goes to full, until I pulled the battery and rebooted.
Is something wrong with my battery?
Thanks in advanced!
Are you using an official battery or a third-party battery?

First, doing the battery drain is effective in calibrating the battery meter but is still probably a bad idea because by doing it you are decreasing how much charge the battery can hold (i.e., a full charge will not last as long). It might not be super noticeable, and doing it once in a blue moon is likely not a big deal, but don't do it often or you'll just end up having to replace your battery. Deleting battery stats should be enough to correct the OP's problem, and allowing your phone to recalibrate under normal use is fine but takes longer.
That said, I do the battery drain anyway, but I would definitely suggest not doing it more than once every 6+ months. Wiping battery stats often is not necessary at all, unless of course you are actually having a problem like the OP is.
Second, you definitely should not clear battery stats AFTER performing a battery drain and recharge. The whole point of doing the battery drain is to let the phone gather new information about the battery since you just wiped the battery stats. If you wipe them again after doing that, the battery drain was useless.
So i recently flashed CleanDFT ROM, first couple of days the meter read out 1 day and 18 hours which im very surprised then it went down to 1 day and 4 hours, now this morning i unplugged and it tells me i got 19 hours left from full charge, should i go by this? or is there something wrong?

Redirecting you to the right place.
If you have just flashed a new rom, in general, you need to go through a couple of battery cycles before the battery read can be accurate. I remember when flashing my ATT FUze I had to wait 2-3 complete charging cycles ie. discharging battery to 10% and charging back to full before I could get accurate reading. If you are experiencing worse battery time than before flashing after 2-3 cycles you might need to reflash the rom; you should see better battery time with custom roms, so I have heard.
I also wouldn't go by the battery saver timing, I would go by wpbench or real time use to get an accurate reading on battery time. I have a 1800 mah battery in my focus and it reads 24 hours on battery life
As far as i know, doesnt all the ROMs have basically the same battery life?
Ill be going out of town sometime this week and ill be out most of the day, i need a rom thatll at least last a whole 12 to 14 hours at the most or whole day at best of just occasional twittering and occasional checks on facebook and probably capture some pictures and a video and maybe an hour at most on music? im sure this phone can handle it but idk what you guys suggest
I have the same issue with ATT samsung focus with Roger latest updates, the battery meter is just not accurate, sometimes full and just reboot upon eject from the micro usb. The battery was fine until recently. Found a few other with the same issue online, no solution available yet.
*pulling out battery doesn't work*
The solution is exactly the same as it is on a laptop.
Lithium ion batteries, and, actually, come to think of it, pretty all rechargeable batteries lose capacity over time. The phone, to begin with, doesn't have a good idea of how much capacity is left, and it has to estimate based on previous performance. This is partially a result of battery manufacturers going as cheap as possible with the circuitry in lithium ion batteries.
The phone needs to figure out how old your battery is. This data is definitely lost with a new rom. Leave it to charge overnight, then unplug it and let the battery run all the way to dead. Charge it again, and your battery percentages should be correct. It may take more than one cycle, but the meter should settle into a correct estimate eventually.
Incorrect battery stats are a possible reason for fluctuations in battery life and reseting them as described in the previous post can help.
Another thing which you can do is use an app like this http://forum.xda-developers.com/showthread.php?t=1328730 to check the reported mV rating of your battery at full charge. That can serve as an indicator of the battery life you can expect with your current battery stats.
