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'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.

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...

Hi folks, I'm running CM6 8/26 nightly with Snap v7.4 kernel with SetCPU set to conservative on 998mhz max and 245mhz min. I'm getting horrid battery life and I think I'm doing something wrong: I wiped battery stats in Clockwork and now my battery SUCKS. -.-
Question is, what its the proper way of calibrating an Evo battery? I've seen the official HTC response but I don't think it's going to make a difference. Isn't there another method that requires you to drain the battery? Any info will be appreciated I've been looking at forums all day.

You can't just wipe battery stats - there's a process to go through. What you're referring to is Cyanogen's battery recalibration method found here. Read through fully before wiping anything.

Actually it is almost as simple as wiping battery stats. That command he gives is what the wipe battery stats command in the recoveries do.
1. Charge battery to full (where it's actually 100% not green light.
2. Boot into recovery wipe battery stats.
3. Fully boot into os then unplug charger.
4. Leave unplugged until the phone shuts itself off.
At that point you should be calibrated.
On a related topic, the Battery Graph app available in the market also has an option to wipe battery stats from within the OS, doesn't it? Might save having to reboot into recovery once you're charged up.
It's a lithium battery. You can't condition it. Just use it as normal and ignore all these placebo effect steps.

They're not calibrating the battery. they're calibrating the phone to know when the battery is really fully charged which, until you do this, is not the case when the charge light turns green.
Regardless, none of this worked. I've quit all services, no sync, auto brightness and wifi and I'm still getting horrible battery life. SetCPU is set to conservative. It's BULL**** my display is on for thirty minutes and the battery dies 20%. I played a game on my friend's iPhone 4 for twenty minutes and his battery barely died 3%. This is really unacceptable and I'm probably going to return my Evo or sell it if the battery life doesn't get better soon from these methods I'm seeing online

Crazy man, maybe something happened cause that is pretty bad.
Have a backup to go back to, prior to this happening, to see if it reverts back to normal?
Naw nothing happened to my phone...... All of us Evo owners should be able to use this beautiful phone with all of the features at max without the battery going to ****. My phone has behaved this way since unboxing. I'm not a big fan of the iPhone 4 but I will give it props on battery life. I have yet to try the longer HTC method but it seems kind of pointless.....
Sent from my PC36100 using XDA App
If it has always been like that then you may have a bad battery, if it started after you wiped the battery data then it is just showing you bad readings.
You should be able to get a good calibration if you reset your battery data again, maybe try through your recovery if possible, and then fully charge it with your phone turned off. Once it is charged you can either use it normally till it dies or you can tether, use gps, watch youtube, etc, and drain the battery down. Just make sure you go from a full charge to the phone shutting itself off without plugging it in to anything. Do that charging with it off and using it till it dies two or three times and your battery stats will be calibrated.
When I did this to mine it showed my battery at 0% for at least half an hour before it finally died, and that was with me listening to pandora and browsing the web.
Edit: FYI, the Evo's talk time is usually between 6.5 to 7.5 hrs, the iPhone 4 is around 7 hours also. If your battery is not lasting that long you need to take it in to sprint and have them give you a new battery.

HTC's method worked wonders for me. i'm a heavy heavy HEAVY user (no, not fat) and I get a good 10 hours with everything besides 4g on plus surfing, gaming and tethering for SEVERAL hours. For all that I do on my EVO 10 hours is HUGE. If I have a moderate day of usage (maybe a little more than moderate for the average user) I get around 19 hours.
Btw none of this will help if you are getting near 100% awake time. If that's the case you need to find the software causing that first.

With phone on, charge until green.
Unplug and turn phone completely off.
Charge phone until green once again.
Unplugand turn on. Once phone had turned completely on turn the phone back off again.
Charge until green one more time then unplug and turn on and you're done!

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 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?

cyan 6 has had terrible battery life for me. so i switched back to leofroyo latest beta rom and got back my 3hr/% standby battery life. with widgets and email checking every 30 minutes. i'm down to 2hr/% in standby. usually in a day i lose 25% battery life with mild internet use and calling. i charge my phone every two days. can't beat that.
Try manually closing all applications & services that are not vital to your phone, then test over a day or two. If that doesn't work, try a different kernel.
Okay I've had about enough of this. It goes down to 15% every day EVEN IF I DON'T USE IT AT ALL
Could someone recommend me the best battery life rom in town, even if it's the stock one?

Don't do this. Draining lithium ion batteries to completely dead is one off the worst things you can do to those batteries. It kills off their capacity
Charge to full, turn off phone and charge again until led turns green again, then boot into recovery and wipe battery stats.

i also like to downclock the processor down to 800mhz with setcpu. definitely helps with the battery drain while using the phone. Non of those 925mv kernels help out in my experience.
Well I run go chat and msn constantly, I use 40 percent display, wifi, 3g, sync, etc and its about double the length I got when it was stock. Right now at 12% and I'm at 16 hours and 32 minutes! I wipe battery stats every time I flash a new radio also it seems to help

Sorry to start another thread on battery issues but I was unable to find a scenario like mine.
Hey everybody, Im new to the android scene, just got my vibrant less than a month ago. Before that I had an Iphone 3g. So far I like the phone but the battery life is horrible. When I surf the internet on wifi or 3g I noticed that I use like 3-5% in a matter of 5 mins. Is this normal? I consider myself to be a light-moderate user and have been getting and average of 12 hours or so on my vibrant. Also if it makes any difference when my phone is idle or being used my temperature runs around the high 80's low 90's but when being charged it drops to the low 80's or high 70's. What is going on? How can I get more 20 hours on my phone? With the iphone I used to get an easy 15 hours and still have like 40-50% remaining.

When I first got the vibrant, it had pretty bad battery life, I would lose like 25% while sleeping 8-10 hrs. So light usage would be like a day. Slowly I started to get longer battery life (2 days on light usage). Recently I could get up to like 3.5 days on real light usage. After updating to JI6, max I can get now is like 3 days. I didn't really do much and I tripled my battery life by just giving it time.
Thanks burntrat I guess ill be patient. And I must mention that I am running stock.i was just worried because my battery temperature gets colder when charging and warmer when idle or running.

Hey burntrat or anybody, has your battery ever acted sort of schizophrenic on you? I mean one day I leave it on standby and its drains like 1% in 7-10 hours another day I leave it on standby and it drains 18% in about 4 hours. Whats going on?

It happens
If ur super concerned get these 2 apps
~juice defender
~ super power
My battery has been draining inconsistently lately. It drains faster in the 50-100% level. Under 50%, it feels like it drains slower while doing the same stuff.

Juice defender doesnt work for me, but ill have to try superpower, anyways I just feel that its weird that without anything changing, my battery drains differently on different days. Burntrat I think thats normal for every phone, the last 50% always seem to drain slower.

if your phone is draining a lot during standby or sleeping. There may be a rogue app out there or an app that didnt shut down properly. (I guess that would mean a rogue app)

I had the same problem, stock task manger doesn't show all of the apps.
Check ur services, go to settings apps manage apps running applications.
Or instead of that I brought the advanced task killer back to check on things
@aamir123 and burntrat: maybe you guys need to calibrate your battery? Also the stock rom usually has a lot of bloatware running in the background. Flashing a custom rom oughta do the trick.

How do you recalibrate the battery?
Sent from my SGH-T959 using XDA App
Try this. Download the system panel app from the market. You can set it to monitor your system and it will chart what applications are running and how much they are using the cpu. If you find you have some unnecessary bloatware running in the background download titanium backup and freeze those apps.

There are a lot of different ways mentioned in different forums. Try this:
Let your battery drain all the way to the point when it turns off by itself.
Charge it while its off until its full.
Unplug it, turn the phone on, then plug it in again.
After it reaches 100, unplug the charger and turn your phone off.
Once off, plug it in and let the charging complete.
Once complete, unplug it and turn the phone on. When everything has loaded, turn the phone off (note: no charging involved in this step.)
After it turns off, charge it one last time until 100%. After this, go into recovery and clear battery info (or cache, I forget). There you go
Oh, and its better if you don't download too many apps that monitor battery usage, cpu etc. cuz they will contribute to the battery consumption.

It isn't a good idea to let your battery drain all the way to zero since it is lithium ion. I think skipping that part and just charging it when it's on to full, then off to full, then on to full, then off to full and then wiping battery stats would suffice. Also you need to have clockwork recovery to wipe battery stats.

When the phone turns off by itself, the battery still has some juice left in it to prevent it from losing the ability to charge, if that's what you meant by not a good idea cuz its lithium ion. If thats not what you meant, then please explain why.

Agreed. In my case, I barely lasted 12 hours on moderate use with any of the JI6 2.1 ROMS (Eugene's, Bionix, Fusion, etc). I think after I updated to 2.2, all of the ROMS have been giving me 18+ hours on moderate-heavy use no matter what modem or kernel I use.
So where is the "unique" problem?
