Hello all, I hope all is well! I have a huge problem... I've been running my evo on the boost network for the last two months and have been getting no more than 4 hours of battery use from every rom I use. I even tried the old destroyer rom and a number of different kernals. Im in need of help as soon as possible!!
How about a little more info. What battery are you using? How old is it? Have u checked to see what is running? Did this start as soon as you switched networks?
Im using the stock battery and its only about 3 months old... It was a claim from asurion. It started happening soon as I switched networks. While on sprint I could easily get a day 1/2 usage.

It could have something to do with your radios, or just be a random coincidence with something else that's causing the drain. I'm not familiar with flashing to Boost at all, so I don't know if you have a different set of radios, PRI/NV, etc. You could try flashing a different radio, newer or older.

Just updated to the latest radios and battery still sucks!
I have Boost too.
The battery drains quicker with low or no signal.
download Spare Parts and check Partial Wake Usage, this will tell you if an app or apps are causing this.
Well I GUESS THIS IS DEAD...
Be sure to calibrate your battery whenever you flash a new ROM to optimize battery life. I prefer to calibrate using this method:
1) While your phone is powered on, charge the battery until the LED turns green.
2) Unplug the phone from the charger and wait until the LED turns off.
3) Now power off your phone.
4) When the phone is off, plug the charger into the phone and charge it until the LED turns green.
5) With the phone still off, unplug the charger and wait until the LED turns off.
6) Now power on the phone.
7) Wait until the phone is booted completely and then power off the phone again.
8) When the phone is off again plug the charger into your phone and charge it until the LED turns green.
9) Now boot your phone into recovery mode and navigate to the "Advanced" option using the volume up and down keys and then choose the option "Wipe Battery Stats."
10) Now reboot your phone and use it normally. You should notice improved battery life.

Wiping battery stats is actually been found to be ineffective/cause more harm than good the best way to actually "calibrate" the battery is to backup your rom flash to aosp or froyo with an sbc kernel let your phone drain til it powers off boot it back up and let it shut off again usually only takes a few mins sometimes it wont power on again, plug in charger wait til red led stops blinking turn the phone on and charge it to 100 uninterupted and leave it plugged in for 15-30 mins at 100% then nandroid back to your back up do this once a month or find an aosp setup u like and stick with it, the myth of sbc damaging li ion batteries is just that a myth newer phones have trickle charging kernels stock now such as the rezound et4g and a few others that i dont remember off the top of my head

Well, everyone has their own opinions. For me, I prefer the method I posted over the app for battery calibration, because I get better results. Also, I've never heard of any negative side-effects from wiping battery stats, but feel free to do what you wish.

Monday and Tuesday I stayed in New Orleans Louisiana. I typically had 5 bars as far as signal goes.. While there I didn't have to charge the phone at all for 2 days with heavy usage might I add. The minute I made it back to my small town, the battery started to drain incredibly fast! So I've come to the conclusion that it is the poor service that drains the battery. With that being said, I would like to thank you all for your input!

Found this on another forum, I have done this a few times myself (do it whenever i flash a new rom because i always clear battery stats, can't hurt). Have found that it does top it up a fair bit. Before doing this i find my desire will drop to +-93% straight off the charger, however this keeps it 100% longer and i actually get to see the numbers 99-94%
Worth a go in my opinion because it only takes 5 mins of your time and can't hurt the phone... So any minor gain from this process is a win...
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.
Mod Edit: There have been a few reports of damaged batteries by people on this thread. There is a chance that this MAY damage your battery. Please bear this in mind if you choose to follow the instructions above.
supportyou and the app!

Also wondering about this
You should wipe battery stats after its fully green (when powered off) then boot the phone back up.
You only need to do this once
I.e.
Charge till full when powered on
power off
charge till full again
boot into recovery wipe stats
boot and continue to use as normal
It works!!!
That's fantastic!
I read this topic this morning and tried immediately. Since this morning i only lost 4% until now. That's great news!
Thx a lot, man!

Hope this will make battery life better. I have the same problem as described in first post (drops immediatly from 99% down to 93% )
Can someone suggest me how should I go about doing this if I use multiple batteries?
I'd imagine the phone can only be calibrated to 1 battery. But if I were to use another battery, would I screw up the calibration to the original batteries?
Right now as it is with moderate usage I need 3 batteries to last me through the day. :S

3 batteries?!
What rom are you using and how exactly are you using your phone?
I have just one battery and it lasts about 2 days with moderate use.
I am using this ROM: (sorry can't post link)
[ROM] Rooted Official HTC Android 2.2 (FroYo) ROM [Market issue fixed]
With my typical usage, I unplugged the phone in the morning from the charger, by the time I knock off from work, I would have left about may be 20%. With stock ROM and a single battery, there is no way that I could last 2 days with one single charge. My main use is web browsing, RSS, Facebook and IM. My estimation of my solid screen time is about 2-3 hours.
So I bought more battery just in case, and played with custom ROMs. I ended up using up a whole battery in 4 hours or so. Definitely something is wrong here. My gut feel is that both the ROM and batteries are suspects. Being a newbie I really need enlightenment.
Is it really needed to wipe the stats? I think I've accidently done this once already... cause the battery life is much better.
since this procedure, my battery stays at 100% since nearly 2 and a half hours now and i did 2 text messeges in between and recently checked the bat about 4 times
this couldnt be possible..
i mean the battery is almost doubled in comparison to how long it lasts before
is this possible??
yes it is possible

i mean in this time the battery would have been dropped to arround 97

Sent from my MIUI powered Evo
You need to condition your battery
I've been dealing with this for ever and I thin kI finally haqve a routine figured out that is getting me CM7 like battery life on a Sense ROM.
1st, I've had the Sedio 3500 for a few months, and like you, I was getting ridiculous drain, until I started sdoing some reading and experimenting.
Here's what I do.
First, off, I have GPS, WIFI and Data disable all the time, unless I need one of them, and then I turn off again when I'm done. I keep my screen off all the time, unless I'm using the phone. I also only use minimal widgets. Calender, Fany Widgets Weather and Forcast, Messages widget, the Beautiful toggle widget for silence and my MIUI Music player on 3 screens, using Rosie. The other 4 screens are just empty.
Second, as for the battery itself, charge the phone for about 8 hrs, and this is the HTC method, unplug it, turn it off, and charge it for another hour, while off.
Unplug it, turn it on for 2 minutes, then power down and plug it in for another hour.
Now, before powering I up, I do the Hoodoo-voodoo-like 10 time unplug thing.
Basically, unplug, light goes off. Plug it in, light is red, wait til it turns green, unplug it and do this 10 times.
Reboot to recovery, wipe battery stats, power up, all while plugged in, and once fully booted, unplug.
I did this today, using the new Koni 3, with Netarchy 4.3.2 SBC HAVS, and riding then used the phone pretty steadily to play Klondike, text, etc an an hour later was just dropping to 99%.
THAT is pretty good, compared to what it used to be like, when it would drop about 1 percentile per minute, even when it was in sleep mode.
Reconditioning is not going to work when you buy a crappy battery. Someone said voodo? You're kidding, right?
Please understand there is no regulation that prevents people from stating their cheap batteries on eBay are 9800mAh but only providing 1000.
I bought 1500mAh eBay batteries that are only 900mAh, verified with equipment.
Check www.batteryboss.org to see what I'm talking about.
Best thing to do? Buy a $1 battery wall charger, two OEM/non-generic htc batteries and carry in your wallet. I wouldn't be surprised if your 3500mAh battery actually packs less juice than the original battery. Oh and your phone is looking like a brick for nothing.
yeah this is why i asked, if you bought a very cheap extended battery, well its rating is different than what it is providing you with
I think I have battery problems solved; Just turn Data off when you're not using it. My phone has been off the charger since Friday night @ 6:30pm. Now it's Sunday @ 9:30am. That's 39 hours and I'm sitting at 63% and I've been texting, making calls, playing a few games, and anytime I need data, I just turn it back on til I'm done and then back off again. That's the only thing I'm doing different now, and before I made that little change, my battery was a good or bad as anyone else's

When I am home, I have WiFi enabled all the time, no 3G/4G. I heard WiFi is better(with good signal) for your battery than 3G enabled. Is this true? My battery lasts about 7-8 hrs of moderate-heavy usage.
Also, here's a thing with all of you trying to tweak your battery to get best performance. From my own experience, I am never a step or two away from a charger be it while I'm on my computer at work, at home or in the car. So what good is it to have the phone out of the charger for days?
I understand WiFI is better, too, from what I've read.
Also, if I can find it, I found a thread on androidfrums from htc that recommends you let your battery drain to below 50% before charging it.
Like you, I have chargers all over, so it's not a big deal, but to be at where I am now, with this experiment on turning data off is simply amazing to me.
Almost 42 hours and at 59%

That is definitely a huge performance improvement but I wonder what's happening with all your apps that need the data sync in the background. I have apps like Pulse, Facebook, K9, Handcent, etc that update every couple of hours or have "push" enabled. What is the trick to allow 3g, 4g, wifi to be enabled automatically only when sync is required and then disabled?
Good question.
All I use is the weather bug and Fany Widgets weather, ad far as widgets that need updating. I think, once they try to update and can't connect, they "freeze" for lack of a better word, until you reconnect and manually update.
It's a little bit of a pain, but for this kind've battery life, I'm not gonna complain
I think what would work is an app that puts the phone in "Airplane Mode" (bad Moment memories ), but allows the calls to come thru. This way there's absolutely no Internet traffic but your Evo is still usable as a phone.
That's probably, basically what I'm doing, but like you, coming from the Moment, Airplane Mode is a bad word....
I got a 3500 battery and get the same fn usage as stock. I've done the usual such as calibrating,wiping stats,drain to 0,and a couple of diff kernels. I am on Cm7 currently with savage.
Any ideas on what else to try? I am lost
Sent from my PC36100 using XDA App
How long have you been trying? It can take up to about 5 different charges(cycles) before your battery gets conditioned. Pretty much using the full battery till its dead and repeating the process. Id say about a good 4 or 5 days before its fully conditioned. Are you also running the SBC kernel version of savage Zen. If you're trying to condition your battery I don't recommend changing kernels during this conditioning process, stick with the same one until you know the battery is ready.

i personally hate cm so many bugs and glitches the final sux however in my trying to give it a shot i tried the savagedzen 1.0.1-cfs-havs-wimax-gb-no-sbc and it behaved alot better and the two days i ran it battery life was really decent compared to what came with cm7
You could have gotten a bad battery.
OK, I have a Sedio 3500 and I had that problem at first too, so here's what I did.
1) Fully charge Battery.
2) Unplug, Turn on for 2 minutes, turn off.
3) Plug in for 1 hour
4) Do the 10 time plug in til light turns green, unplug til it turns green again, etc, etc.
5) Turn on the phone, and anytime you are not using data or wifi, etc, turn them off. I do this religiously, turning it on when i need to get on the browser, or hit up any apps that use data, then I turn it off again, qand use WiFi over Mobile Data anytime you can.
I left today at full charge at 1PM, and here at 2AM, I'm at 83% and I've been texting all day, using the camera at a concert I was at, uploading the pics to facebook via WiFi, etc, so it's not like I just left it in my pocket all night.

What are you synching during the day and at what intervals? Governor and Min Max Speeds? Do you live/work in a crappy signal area? Use a lot of bluetooth or wifi?
I uninstalled facebook and twitter and whatever else asks you for your first born child permission wise, and stopped Maps from starting at basically five or six different system-wide events.

everything is stock in terms of intervals, and governor, and cpu speeds.
I travel all over, so my signal strength goes up and and down. But I think you may have hit the problem.
Before flashing (stock) I pretty much always had 4-5 bars wherever. After flashing (s-off, root, etc), I have never had above 2 bars.
Using my home as an example, I normally had 5 bars of service. Now looking at my phone, I have 1.
Internet speeds are fine (250kb/s down 87kb/s up). Phone call quality is the same.
My signal Strength in front of my computer is -77dbm. Outside my front door is -102dbm.
I wasn't getting the battery life i was, so i did flash v9 and i'm back at 1% battery loss while phone is unused. I wasn't getting that with v10 or v 10.5. I could barely get a day between charge. I should get 2 days with v9 because i did before.

You can try other radios. I understand some have better effects than others with each handset.
Also, I tend to update PRL and such before installing a new ROM using a stock ROM.
I have already tried the two recommended radios. The funny part is 0322 was the radio my phone had before I hacked it.
after flashing each rom you have to program and that updates the PRL anyways.
But just to be sure i did the roaming capabilities, and no change.
Ill try v9 of the kernel. anything else?

Na, the phone was fine on battery before the hack, from past experiences it's always been even better after. Maybe I'll restock and see if that helps.
Yeah Facebook has been performing poorly on many people's phones especially while on 3g. Sometimes loading very slowly and sometimes not at all. It has also been causing a wake lock problem which I personally experienced that wakes your phone while it should be asleep (not the screen just the os.) That causes battery life to be poor for many users.
I hear that FriendCaster is much better if you want an app to replace the app! Or some are using the mobile site if they don't care about notifications. Personally I just uninstalled Facebook after I started having problems and haven't been on Facebook since.
Try uninstalling the app and see if that helps. It nearly doubled my battery life when I did.

If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors, and re-calibrating the battery along with these steps may help, may not. But, worth a try anyhow:
1. Take the case off your device (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your device to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your device completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM (if installed) or use Rom Manager (is device is supported).
Do not disconnect it from the charger still!
12. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Before going to sleep - Install Watchdog Task Manager Lite from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
15. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
16. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.

If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors, and re-calibrating the battery along with these steps may help, may not. But, worth a try anyhow:
1. Take the case off your device (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your device to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your device completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).

Yeah Facebook has been performing poorly on many people's phones especially while on 3g. Sometimes loading very slowly and sometimes not at all. It has also been causing a wake lock problem which I personally experienced that wakes your phone while it should be asleep (not the screen just the os.) That causes battery life to be poor for many users.
I hear that FriendCaster is much better if you want an app to replace the app! Or some are using the mobile site if they don't care about notifications. Personally I just uninstalled Facebook after I started having problems and haven't been on Facebook since.
Try uninstalling the app and see if that helps. It nearly doubled my battery life when I did.

I also support FriendCaster. The facebook app hardly worked when I used it. The only time it half worked was when I was home and on wifi. I actually like what FriendCaster...I like what it does with the layout and I feel it's a lot more intuitive then the official app anyway. Plus for some reason facebook had become a datahog. This could be OPs problem in terms of battery drainage because Im pretty sure they download a lot in the background.
Hi all,
My SGS3 suddenly since last night has not been able to recharge, battery critically low. I have tried a few chargers, and rebooted several times.
Can a battery go bad this fast, because looks like it was charging and running fine the day before.
Thanks

Have you tried loading a stock ROM on there just to be sure it's not software causing harm to your battery? Not sure if your provider will warranty your battery if it is indeed your battery.
Good luck!
Hi, thanks for your response
It actually is stock rom, sorry forgot to mention it. It is rooted, but I never replaced the rom, just put in CWM recovery. I just moved from rogers to virgin mobile last night, just changed sim card. But the multiple reboots killed a maybe already weak battery?
Thanks

You should download and install better battery stats, it may help you find out if its being kept awake and draining quickly that way

Thanks for your response, necrowakker.
I guess that I forgot to mention as well that the phone was shut off during a recharge, and upon powering up, it still it complaining to plug it into a wall charger.
Like it was never plugged in.

When you rooted your phone was the kernel changed? .. I've had experience with some custom kernels not reading the battery correctly when off, and only after switching it on it still States its low til a little while later it actually looks like its charging .. ( like the battery level goes up over time) while being off the charger.
If thats not the case, try charging your phone again, but while its on after you know its definitely discharged and not just a ROM memory issue. If you turn it off to keep from getting calls during the night switch on airplane mode to keep that from happening. And check if your battery does on fact charge correctly. ...
After 3 full charges and discharges your battery still gives you bother. Then you can either look into what process it was when you rooted,
if it did change anything more than just giving you more access, or see about a hardware replacement, if it is under warranty, and you can take the flash counter back down to zero (if it counted up) and unroot it.
Also using unsupported chargers over the recommended charge rate for your phone, could have done it damage but that's a long shot with today's safety measures on phones.
Edit:
Don't forget to install better battery stats too, just for checking and reporting. Stable ROMs should be able to handle over 300 hours up time before needing a reboot. So using airplane mode should not bother your phone too much

Thanks for all that info.
The phone has been rooted for at least 6 months now. It has been running very good until this morning. No kernel was changed for the rooting. I just wanted titanium backup to work.
I am still presuming that maybe the battery was weak, and when I was changing out the sim card of the service providers, I did reboot about 15 - 20 times to try to get all the services running, maybe that was enough to kill a battery.

I've don't some silly **** with powering and charging and pulling batteries for every reason, I can't see Samsung giving you a bad battery if its worked fine for 6 months, you'd probably know within the first 6 weeks if it was faulty. ...
It may easily be a software memory issue with the battery that's confused it. If you are using cwm as a recovery it may have the erase battery stats option on it, if so give it go,
charge your battery to 100, allow it to drop to zero, or til it shuts down, plug in, power it on allow to boot, and leave to charge to 100,
once that full discharge and recharge is done, your battery has its full stats. If it gives you hassle after this point, think about buying a registered Samsung replacement for your phone.
