I'm having an issue with my battery. I am running the latest build of ViperInc on it and the battery life is great. But something weird happens when the battery gets low. from 20-12% battery left it runs fine. But once it hits 12% or even 11% it jumps down straight down to 6% and then powers down. I've tried cycling it a few times.
I think it actually needs a calibration. I know I used to have some option in CWM recovery that would reset battery stats but not i use TWRP.
Any suggestions?
That has been proven to not really be affective. Do you run any kind of battery saving apps.

You're working off a lot of outdated information. We don't use Ni-Cad batteries in our phones, fully discharging Li-Ion causes more harm than good. The wipe battery stats feature in recovery was removed about a year ago because it gave false impressions about "calibrating" your battery. In actually, it only wiped the statistics... strange right? A new battery costs around $7 on Amazon or eBay, have you considered that?

Gotcha. I always read conflicting stuff about it whether cycling works or not.
I know batteries are only 7 bucks but I don't have any issues with it and it rarely gets down that low unless i forget my charger after a day of classes and work. Was just hoping there was some way to even have a makeshift fix.
I appreciate your help

I have been flashing back and forth ROM and Mods... I felt my battery getting worse compare to stock (stock Rom removed lot of ATT craps and other unused app).
Now doesn't what Rom i use: S8, Unname and CM7. My battery died at the end of the day which should last 1.5 days as my normal use.
Hmmm... well I jumped onto the ship already.
But I have to thanks for all developers that cook Rom. You guys are best.
Battery lifestyle will improve once you build up cache. Was battery life good when you first got your phone? Probably not. After awhile battery life gets a bit better.
Sent from a Galaxy far far away...
I noticed the same thing when I flashed from UnNamed to S8.
I followed some other users' suggestions and reflashed at 100% battery life, allowed the battery to discharge all the way until the phone died, then charged all the way to 100% again without taking it off the charger. I just got 25 hours with moderate usage and about 4 hours of screen-on time.
download the batteryCalibration app from the market, it requires root and makes you charge to 100% first. After that let it drain and it should do better after a couple cycles.
If you delete your battery stats in clockwork the phone relearns them and works better. But it will be ****ty for awhile

None of these do jack on our phone. I've read the kernel source for our fuel gauge driver, clearly none of you haven't and are blindly applying HTCisms to a Samsung phone even though I've posted MANY times that diddling with batterystats does NOTHING WHATSOEVER on this phone.
If someone's experiencing bad battery life after flashing a new ROM, especially a debloated one like Unnamed or S8, they most likely installed a drainer app.
If you run Skype, nuke that crap from your phone ASAP. It's a known battery drainer, and it's particularly insidious because of how it drains the battery - the usage shows up as Android OS but it's Skype that is at fault.
So I was one of those who was finding my battery life to not be sufficient on the Photon and bought the Seidio extended battery. First thought is that it does make the phone heavier, but I can deal with that. Not a deal breaker.
My issue is that the Photon doesn't recognize the fact that I now have the extended battery. I've spent the last two days using Battery calibration software (charging overnight to 100%) and then trying to discharge completely and recharge. The problem is that the phone continually is showing 1% for almost 3-4 hours if not longer. I can't get it to recognize that there is more juice in there.
While it's great that it seems to be working well (first real work day with it today), having the battery drain like mad (or seemingly) and then sitting at 1% for half or more of the day and not knowing when it will die is a problem.
I wonder if this is why the stock seemed to drain so quickly - maybe it's a programming bug? Firmware bug? I dunno. In any event, any suggestions on how to make the phone actually see that there's more juice would be great.
As an FYI I've used "Battery Calibrator" - both of them and Battery Drainer and Fast Discharge to get the phone down. I am rooted, but everything is stock other then the root itself.
I spoke with Sedio - they said I should unroot the phone and do a master reset. I can't believe that would make it work better - but I'd rather ask this community first.
Thanks!
Check in the accessory forum there is a couple things on the Seidio battery and some people there that have them may have run into the same issue and have a fix for it.
Can't seem to find a thread where people talk about aa problem with it. Can you point me in the right direction?

have this battery, after the initial eight cycles allow nearly complete discharge, allow to charge for at least two hours after phone indicates battery is fully charged..... my battery is working very well, just use a battery indicator from the market, I didnt piss around with any battery calibrators, think this might be your problem, have never used a calibrator on any of my phones with extended batteries. Android market probly has an app to wipe your ass.....do you really need it? Hope the analogy is clear to you.
LOL fair enough. I did do the full flash this morning - so I'm unrooted.. Hasn't seemed to help - drain looks the same.. Been through about 6 full cycles since I got the battery. What battery indicator program are you using? I have battery circle and it's got the same issue.
Again - battery lasts just fine - but the amount of power left is never accurately indicated to me - and that's the problem.
I have had many Seidio Batteries, dating back to the OG EVO. The problem I have with this particular battery is this: These batteries work "properly" when charged on an Independent Charger, NOT inside the phone. If you Cycle/Discharge/Charge with this Battery on an External Charger, the Battery should calibrate correctly. I still believe the issue with charging within the phone, is that the Mopho doesnt accurately measure the Battery Capacity. Try and External Charger, should solve your problems....
riggy
Riggy -
Battery def is charging fully as I get tons of life - the MoPho only shows 1% left though for hours on end.. It's a matter of it doesn't see the correct amount of juice left. As per cutter2668, it may just be a situation of discharge - charge. Dunno.
As an FYI I did the full flash this morning, and I haven't really seen a difference in the phone telling me how much batt life I had left. I'll give it another day and hopefully after a period of time it will start reflecting a true number.
I have also emailed Seidio support directly on the issue.
So as an update, seidio is going to be sending along a new battery to see if that solves the issue. I guess we will see!

Any luck on the new battery? Just noticed my extended battery is doing the same thing. :-(
So things still aren't working right. Battery shows 1 percent for half my day and the Photon just doesn't know. However, I read a thread on Amazon about a generic extended battery and someone suggested using Battery Monitor and using Voltage Based monitoring. Its certainly not perfect but it gives you a somewhat accurate reads on remaining battery. I truely wonder if this is OS or a hardware limitation.
Oh well.

Maybe this is an Android issue, I've read the LG Optimus S has the same problem with extended batteries.
finally found a thread on this issue after posting
http://forum.xda-developers.com/showthread.php?t=1748301
sorry mods, pls delete
Me too ... it's driving me nuts.
I am experiencing this. My battery life is horrendous. Even when I barely touch the phone the battery drains extremely quickly. I have already rooted the phone with a few different roms with the battery setting "fix" to no avail. I'm on at&t. I have disabled wifi and gps. I have tried to use both the stock app killers and 3rd party ones recommended by these forums. My battery monitoring apps (both stock and 3rd party) consistently attribute the battery loss (always more than 90% of battery use) to an android system app. The android system app or file changes from day to day seemingly randomly. Files have included: UltaCfg, com.samsung.app.playreadyui and security storage.
Any help will be extremely* appreciated. I love the phone but it is nearly useless in this state.

I have been experiencing some serious battery drain issues. Looking at my battery stats, "Android System" is responsible for over half of the drainage. These are the only apps that run constantly besides those which the phone requires to operate:
- SetCPU

- LBE Privacy Guard
- avast! Mobile Security
other phone info is in sig. Any insight/advice??

I am draining my battery as quickly as I can (streaming Netflix through 4G LTE with max screen brightness, max overlclock w/ performance gov) and then i'm going to power off and do a full recharge. this seemed to have fixed similar issues in this thread:
http://forum.xda-developers.com/showthread.php?t=1756776
let you know the results.
edit: suppose i should say that i was not experiencing this issue until i updated KT747 this morning.
this is what i did:
1) drain the battery completely. let the phone die.
2) charge to 100%. do not power the phone on until it is completely charged to 100%.
3) when i powered the phone on I was at 99%. i plugged it in and it went to 100% in about 2 minutes.
this seems to have completely solved my problem. the android system has gone from using 57% of the battery to 6%. it seems like the kernel i was using vastly overestimates the percentage of the battery to allocate to the android system until it "learns" the capacity of the battery

I am also a Telus user. I had big time battery drain issues even with trying everything: enabling power savings mode, running Juice Defender, using wifi more, using darker wallpaper, keeping a closer eye on syncing operations, screen brightness and some other stuff.
After about 10 days I went back to the vendor (Futureshop) and convinced them to give me an exchange on the battery. They have a 14 day return/exchange policy for cell phones if you are not completely satisfied. I took some screenshots to argue my case. Thankfully the rep said ok and further explained how much power an AMOLED screen uses. I really didn't want to convince him that I am quite informed on battery drain issus and took the new battery and ran!
Conclusion is the new battery is so much better it's like night and day. I have the capacity now that others have been raving about.
If you can exchange the battery, do it. Then get the new battery and charge it up fully first thing.
I was really suffering from massive battery drain....see here - http://forum.xda-developers.com/showthread.php?t=1933012
ive now found out that i am having a very wierd problem...My rom is showing some 30% battery while 4ext shows 50%......Sometimes it is exactly the opposite....Once i discharged my phone to 2% (rom reading) and when i saw in recovery it says 17%....
I have completed many many cycles of battery from charging to full....and discharge to 0.....Also i used the battery callibration app SEVERAL times!!!!........But nothing seems to work...
Can somebody help...Please

I had this issue with my old battery and old charger,
Now I dont use my phone while charging , I charge other batteries with the wall charger while using other ones and everything is fine now.... battery % seems to be same in both android and recovery.
I have that same issue too. Lol maybe the recovery can't read the battery correctly. It'll show up higher in recovery and then when I reboot, it will read the same way like in recovery. Tried numerous batteries with the same result. Although I havnt tried battery calibrating. Ill give that a shot.
Is there any solution ??
Try klect's solution and go into recovery, wipe battery stats. Then let your battery drain and die. Then charge your battery back to 100% with no interuptions like pulling your phone off the charger too soon. When you wipe your batt stats you are getting ready to recaliberate your battery. After you let it charge to 100 percent. Let it drain to 0 a couple times to recondition your battery.
You do know that the evo 3D gives around 3 hrs of screen time dont you? even on stock rom on normal usage. If you have the wifi on all the times you'll get around 2:30 maybe 3 on a full charge.
Your battery certainly is draining faster than usual but have you tried keeping it idle and seeing what kind of drain you get? From that screenshot in the other thread it seems like your phone is getting some heavy wifi browsing or something (and do check if facebook or email apps are the culprit. Having push email on drains a lot)
And the recovery/rom reading wrong stats happens all the time. just recalibrate your battery like these good folks here have already suggested
Yes i keep wifi on all the time...
But once i kept my locked for abot 3 hours after full charge...when i unlocked it showed 99%...i was happy and i didn't do anything just surfing my screens it dropped very very fast to some 70 % !!!!
Also please hit our thank you buttons please. Even if you didn't get the exact answers you wanted. It's appreciated for helping one another.
you really should check your apps battery usage using one of the apps ramjet73 told you about
ramjet73 said:
There are a bunch of tips here.
Usually that kind of drain is caused by an app. Try running a stock ROM for a day or two and see if the issues go away. Or use one of the battery monitoring apps (BetterBatteryStats, SystemPanel Standard, Battery Monitor Widget) to determine which app is causing your drain.
It may take some work on your part to isolate the problem since there is no global solution to battery problems.

top culprits are mostly facebook,email exchange,google maps and pretty much anything that syncs alot
Also try using you phone on min brightness auto brightness is also a battery killer
I cant beleive no one asked you this but which kernel are you using? And is it overclocked?
I am on mwakious 13.1 default...no changes to it
OK so to calibrate my new battery charge to full unplug then use till it dies then recharge to full and that's it? Is one cycle enough?
Thanks

there is no calibrating requirement for lithium ion batteries...
Not sure if it is good to let it die. I was told on the gnex that running it till it dies was not good for thag type of battery? Maybe someone with more knowledge can clarify that.

I know this is slightly a different question. My issue is after you flash a new rom it seems the % is not entirely accurate. It will act fine for a while and then when u get to like less then 10% it drops dramatically like it wasnt reading it correctly or just like today I turned the phone off and did a reboot at 96% and when it powered on it was at 92% which is quite a bit of time on the note 2.
How do you get your battery reading accurate again after you have flashed a new rom? This has happened with my Bionic in the past as well. Thanks.

Correct, it is bad to deep discharge Lithium Ion batteries.

100-90% can vary depending on when you take it off of the charger. Basically, once the battery hits 100% on the charger, it will start slowly discharging itself to avoid damage. Once it get below a certain threshold, it will charge back up to capacity again.
Regarding rebooting, that process is fairly system intensive and it is natural to lose some battery life. In addition, prior to the reboot the OS is calculating a rough estimate of the percentage left partially based on previous use. So for example, if your phone was in deep sleep for hours, then you reboot where the CPU ramps up significantly, the percentage will alter to more accurately reflect the charge left in the battery.
In short, there is never a need to "calibrate" a battery, the OS will sort it out itself even after flashing different ROMs and it can take a couple days for kernels to settle.
