When you recalibrate your battery, it takes a few life cycles for the battery to stabilize and for Android to get an accurate reading. First life cycle is alway short. Of course, don't play with ROMs so much it may damage your phones read only memory.
I will post my battery life soon, I'm still waiting for the battery to deplete, I haven't recharged my phone in 4 days now after I calibrated my battery.

Wow 4days is huge,iam getting hardly 1day battery after calibrating yesterday....
Actually i removed my phone before getting the 100% notification....
So should i wait for battery to improve???
By the way,when did you calibrate???
Should i calibrate again????
If this wont work i will try terminal emulator method...
So in this method do we need to charge 100% or discharge completely??
Some precautions or just write those commands at any point of charge???
Iam wondering how to thank from the xda app
Thnx to both of u

Same problem here.
Battery drained from 100% to 60% in 3 hours, then to 15% after 5 hours. phone super hot! Widget showed temp 42°C !
Not even used the phone for more than 15 min! REALLY!
Then calibrated before 3 days, now a max of 1 day battery backup only.
Plz help.
And 1 life cycle means I must let the phone charge 100% then let it discharge till it's switched off.
And I should repeat the cycle.correct me if I am wrong.
And I have the habit of not charging to 100% in a single charge session, 2-3 breaks, should I change it?
clarkkov said:
If your phone is hot without you using it, something is running in the background, that shouldn't. Which ROM are you using and which tweaks/fixes have you applied?
One battery life cycle means battery drain from 100% (fully charged) to 1% (fully discharged). Your phone does not have to turn itself off, but make sure it is at 1% when you begin to charge it again. This is important only for a few cycles after calibration, afterwards you are free to charge it as you wish, but while calibrating it's highly recommended that you don't interrupt the charging process (4Hrs).

I am using rooted jpd from samfirmware, no fixes except sdcard speed fix, previously it used to give a good battery backup.
And apps do run in background.
Should I set autokill level to high in task killer?
And I will take care of charging.
Thanks for support.
on DDJP2.. getting a horrible backup since i have updated thru KIES. generally on jg6 used to get almost 1.5 days which has come down to 12-16 hours now. trying to calibrate my battery with app 'battery calibration'.. calibrated once.. but still no change. read somewhr that we get the same backup for first few times even after calibrating.. but to get sure i am writing down my process.. plz chk if m doing right or not ..
1. plug in phone with charger
2. wait till 100%.
3. press battery calibration or delete batterystat.bin with the help of root explorer.
4. unplug charger and use it till it discharges completely.
5. charge again to 100%.
plzzzz chk and tell.
plzz someone reply.
I have a question about batery drain. Apps on backgroung are drainning lot of batery? May i have to stop them always?

Yes.
You need to be aware that wireless services are draining the battery the most. If you are not using 3G - switch it off, same with BT and WIFI. Widgets that update frequently also drain the battery fast, background data, auto sync services/features are battery killers, too.

Thanx for the reply.. i have calibrated once more.. but already showing 80% after hardly 2 hrs.. no clue whats going on... ppl with JP2 shud come up with thr battery backup to get confirmed.
and last thing am waiting for is that someone said .. battery life is worse for first few cycles after the calibration... thats the last hope... :'(

Thx for the aswer, i thought that all the background data are drain lot of battery. I'll try to calibrate and switch off all the thing i can and see if my battery lives more time
Hey there,
scince I use BatteryLeftWidget, I can see that my battery voltage only reches 4171mVolt.
So, batterystat.bin delete doesnt help, so anyone an idea where to put the 4200mV ?
Standart disclaimer: I am not responsible if you break things by following this guide, though I will be genuinely surprised if you do.
Credits: This fix is a combination of battery management techniques discussed in the Atrix forums + a technique that I originally found in a Milestone forum (I didn't invent it, but I am too lazy to search who originally posted it ).
This worked in fixing the problem for me (the same problem that I see many others are writing about on the forums), but I can't guarantee it will work for you.
Who should use this? (aka your battery problem symptoms are
1. Battery life on 2.3.4 is significantly worse for you than before.
2. Battery stats are jumping and showing inconsistent information.
3. Your phone loses 30%-60% just by sitting there overnight.
4. Phone idle draining 30%-60% of battery just by sitting there overnight.
5. After flashing a couple of roms, your battery stats got messed up and the phone thinks it's at 100% charge while it's not.
I personally started having battery problems after flashing a couple of roms, applying 1% battery mod and despite flashing jug6ernaut's CWM battery fix.
When I went to bed with a 100% charge, I would wake up to a 50% charge, with Phone Idle process showing up as massacring the battery. The steps below successfully fixed the problem for me.
Prerequisites:
1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)
2. Wall Charger
3. jug6ernaut's CWM battery fix (put it on your SD card you will need it later!) I have also attached it to this post.
4. Battery Calibration app from the market
5. Watchdog Lite or Full from the market
Instructions:
It's best to complete this procedure in the evening before going to bed, so you can leave it at 100% overnight and check in the morning if the drainage issue is fixed!!!
The whole procedure along with recalibration might take up to 5-6 hours!
1. Take the case off your Atrix (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 Atrix 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%. (Explanatory pic, needed number circled in red). Write it down.
My Atrix was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix 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%. Back when I used a Milestone, it usually showed 60% after doing this.
10. Let it sit there charging for 2-3 hours.
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, turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Install jug6ernaut's CWM battery fix (even if you had it installed before), do not reboot yet.
Do not disconnect it from the charger still!
13. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
14. When the phone turns on, go into BatteryCalibration 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 4200MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
15. Before going to sleep - Install Watchdog 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!
16. 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.
17. 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.
(Your general battery capacity should have increased, even if something still was draining the battery, you will be able to find the infringing process in WatchDog with the settings we've set up in step 15 )
That's all folks! Please report your success / lack of such here. Also, feel free to ask questions, and I along with other users with answer them according to our ability.
I will later add a section on "good practices for battery usage" with tips and tricks.
Cheers!
Attached are screenshots of my results after calibration: This was under moderate usage. Pretty damn good if you ask me.
Post-calibration methods of improving Battery Life
Updated: Post#2 will explain how to solve battery drainage problems when recalibration wasn't enough. It will also explain how battery reporting works, common practices, tips, tricks, etc.
Battery Tips / Tricks / Common Practices
Important things to know:
1. It's important to understand how battery indicator on Android works and how Android manages / reports your battery life. Please read this article:
Your Smartphone’s Battery Gauge is Lying to You (and it’s not such a bad thing)
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
2. Li-ion batteries used in modern smartphones don't have "charge memory". Partial charges won't hurt the battery (e.g. charging from 60% to 80% or from 10% to 50% etc). Feel free to give your phone small charges whenever you have time and need the phone to last longer.
3. Smartphone batteries don't like to be completely discharged or to be kept at 100% capacity for extended periods of time (this actually damages batteries over time). But worry not, the battery software prevents this from happening for you. That's why some of your phones never get to 100% or drop from 100% to 90% minutes after you disconnct the phone from a charger.
4. All batteries gradually lose a small percentage of their capacity after a certain amount of charge cycles. It's a natural part of life. It's always nice to have a spare battery or to purchase a replacement when your current battery isn't to the task anymore.
5. Don't pay much attention to the battery %, just use your phones. I know it's very tempting to track your battery usage every 15 minutes and try to find problems. Been there myself. Thing is, if you do this, you might start thinking you have problems, when you don't have any.
Bottom line - just try to use your phone and not mess with the battery unless problems become really apparent.
------------------------------------------------------------------------------
Other proven ways to improve Battery Life
If you have re-calibrated to a full capacity (4200mv) but your battery still drains terribly - follow these steps to pin point the problem.
1. Find which app / process is draining the battery.
If you get lucky, the infringing app will show up directly under the stock "Battery Usage" statistics. However, in most cases "Battery Usage" isn't very informative. Most people report that they only see "Phone Idle" consuming most of the battery without much insight into the details.
Things to do:
- install Watchdog, go to preferences, set CPU threshhold to 20% (or even lower if it's not enough), check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20%(or even lower if it's not enough) as well. Run it for a couple of days.
If you start getting frequent Watchdog notifications about a certain app breaching the threshold - uninstall it, find an alternative.
- install BetterBatteryStats from here -
http://forum.xda-developers.com/showthread.php?t=1179809 run it for a couple of days and monitor apps / processes that are using up more wakelocks than they should.
Once you find the infringing app - uninstall it, if it's a process - find out if it's safe to stop / freeze before doing anything.
2. Freeze bloatware aka "stop the problem before it becomes a problem."
Unless you are running CM7, your rom is based on stock 2.3.4 and still has blur in it. Blur apps and processes might be running without you even using them and sucking out precious batter life while they are at it.
Things to do:
- Get TitaniumBackup, freeze all bloatware that is mentioned as "safe" in this thread -
http://forum.xda-developers.com/showthread.php?t=1182663
Use your phone for a couple of days afterwards and watch for improvements.
If these software tweaks aren't enough, the problem might be with your system setup. Go through these steps which should hopefully fix your setup in favor of awesome battery life:
3. Flash a custom kernel, set up battery saving profiles.
Many people have reported success with this step. Custom kernels are not just for overclocking. A custom kernel with smart profiles will definitely give definitely extend your phones operating life during the day.
Things to do:
- Get a custom kernel., the popular choice on here seems to be faux'es kernel, so I recommend it -
http://forum.xda-developers.com/showthread.php?t=1156040
Get one of the battery saving SetCpu profiles along with it. Basically, a good battery saving profile looks something like this:
- absolute minimum CPU clock with screen off (something like 275 Mhz)
- lowering CPU clock with temperature > 50C (something like ~800Mhz)
- lowering CPU clock when battery < 30% (something like ~800Mhz)
Many people reported success in using such profile for lowering "Phone Idle" drain.
4. Flash a different radio.
WARNING: Be extremely careful with this. Flashing a wrong radio is the right way to hard brick your phone.
Although some people are reporting to have fixed battery drainage by trying out a different radio, I seriously wouldn't recommend going on a flashing spree unless you know what you are doing.
My advice here: flash the latest 2.3.4 for your carrier if you haven't yet. From there on, experiment at your own risk.
5. Disable Data and Wifi when idle either manually or with an app."
I seriously get surprised every time someone says they have a horrible battery life, when they keep an internet connection on at all times. Constant data always = battery drain.
Things to do:
- use apps like Green Power to disable data / wifi for you when you are not using it
- learn to turn off your internet connection manually
6. If all else fails - start over from scratch (read: clean install a rom).
I've heard reports of people getting better life with Froyo than GB, or that a specific custom ROM solved their problem for them. A million dollar question: if it works for you, why not use it?
Things to do:
- try a ROM without blur, like CM7
- try Ninja Speed Freak (developer and many users reported great battery life)
- if battery life is your top concern - try Froyo

Many thanks! Have pass about three days reading about the battery issues/solutions, and I was getting confused by so many info! Will try it tonight!
PS: Does the jug6ernaut's CWM battery fix works for the Orange 2.3.4 ?

Are you using stock Orange 2.3.4 rom?
If yes, your Rom might not have the battery jumping problem. You can still use this guide without the battery fix to recalibrate.
Let's wait for someone with Orange 2.3.4 to confirm if jug6ernaut's CWM battery fix can be used or not.
Indeed, I have not the battery jump issue, but I'm exprimenting some weird behavior...
like when I restart the phone, it shows about 10% higher than before. I tried this multiples times yesterday. When it was about 40%, it starts to drop suddenly, 'till it got to 18% and get back to normal decrease to 4%, 2~3 hours later...
See the images attached, the red circles are the times I rebooted it and the blue arrow is when it drops suddenly...
Question on step 4. To confirm, we shouldn't click on anything in BatteryCalibration, all that needs to be done is take note on the MV number, correct?

Did it only start doing this on 2.3.4 or you haven't checked before? Anyway, I would do the calibration to see if it changes anything.

No clicking in step 4. Just write down or remember the MV number.
Yes it just starts when updating to 2.3.4... In the first days I got the impression of lower battery level, so reading the forums I saw the restart/level change problem, and tested it

You probably updated to 2.3.4 while not at 100% battery level, and it messed up your battery stat. So, yes, do all the steps in this guide except for jug6ernaut's battery fix part.
thanks, ill give this a shot....again.....tonight and hopefully it will fix my issue.

I'm on a rooted stock GB and I'm having the problem where the battery usage stats are inaccurate and won't got below 90% after using it all day. This all started after I used Battery Calibration. Do you think that this would help correct the problem?
Edit: Also, would I need to complete all of the steps including the CWM part? I haven't flashed any roms yet, so I don't know if this would be necessary.

Seems like you used Battery Calibration while not at 100% charge and your battery stats got messed up.
The reason I recommend using CWM is because the battery stats file is created on each boot. So, with my instructions you can charge the phone to 100% while it's off and wipe the messed up stats before it boots.
You can try using my instructions, without the CWM part, except you need to wipe your battery stats with Battery Calibration app after step 4.
lol i left pandora on since this morning and its only at 67%. ugh, when i wanna force drain the battery it goes slow as hell but when i wanna conserve battery live for usage it drains quick. hahaha.
I just flashed navalynt's πCrust rom fully charged, cleared stats through cwm, booted and now i'm close to 3days.

lol yes. I used video playback to drain mine. But if it's really a PITA, you can always just leave it till tomorrow to discharge naturally.

Yep, that's why flashing only when at 100% charge always pays off.
I get the same results by booting to CWM, wiping battery stats, rebooting, starting Battery Calibration, plugging phone into wall charger, charging to 100% (4197mv for me), and then calibrating with Battery Calibration. I start this process at any battery percentage, and have been doing this for a long time now. I have never had to deplete my battery until my phone shuts off, and get great battery life.

After the calibration I had 4200mv, so it seems like you are doing things right in regards to the battery.
"Taking the battery out and putting it back in" trick works wonders though in restoring battery life to maximum state (if you had it decrease for some reason). I've tested it multiple times even back when I had the Milestone.
Hey guys, i have a problem concerning the battery life of my HTC Hero with FroydVillain 1.7.3 (Android v2.2.1)
In the last couple of days my battery goes down by 10-12% per hour without even touching the phone. I tried factory reset, wiped sd card and reflashed, flashed CM7 but still the battery issue didn't go away.
I charge it 100% before i go to bed at 11.30 and when i wake up at 7 the phone is completely powered off..
The thing that consumes my battery is the process "Android OS". I read about it on the internet, but all threads were SGS2..
The strange thing is that it's CPU usage time according to the battery stats is 1h 21m after 3 hours of sleep.. Is this normal??
I have everything turned off - wifi, gps, mobile data, auto sync, background sync and still the drain continues.
Has anyone had this kind of issues and possibly a solution?
Or should i buy a new battery?

I have also been experiencing battery issues with Froyd lately, but not to the same degree as you are. My solution was to wipe and install another 2.2.1 based ROM. This new ROM is acting normally in terms of battery life.
With Froyd, my battery was acting "weird" in terms of overall battery life. Once I got about 3 good discharge / charge cycles in a row things seemed to improve.
Another thing to consider is did you recently install any new apps? Some apps don't play nice and cause the phone to not enter sleep state OR cause excess CPU usage.
Some people might say "wipe battery stats" but some Google Engineer / Developer has recently dispelled that myth... https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
Good luck!
It's not from any app. Last night i wiped my sd card, wiped everything from recovery and flashed Froyd. I used it all day without installing anything besided battery graph to monitor my battery usage. it's something from the OS itself i guess..
The funny thing is that it seems that in the past two hours the drain has disappeared and now the battery is reducing by ~1% per hour and i haven't done anything during that time, except 2 calls under a minute each and 1 sms.
How old is ur battery? Did you consider that it might be physically related? Not because of the processes or so?
One more thing I noticed - if I charge by ac outlet, it charges faster, and lasts longer, if I charge by computer usb port, it charges really slowly and battery drains way faster... I don't know about battery life, maybe from ac outlet it dies faster, but 2 years of using it and still 1.5 day of normal use...
Thanks for the replies guys! I found the problem, it was my radio.
I flashed the latest radio and now my hero's battery life is better than before!

Looks like you have a battery problem. OS does not really kill batteries, you can see more or less the same performance if there are no background apps eating your power.
Check these batteries for your Hero. These are top quality and many users vouch for them.
HTC Hero Mugen Power batteries
@saj222 i'm now running the same radio as the one in your signature. before that i was with 09.05 or sth like that..
@porcupineli my hero is second hand with about a year of usage before me. i have it for about 2 months now. Since the phone costed me $90 i don't think i can pay $70 for a battery.. I was thinking of buying this one

Is it any good?
hoping to get some help...
i have update my SM-N9005 from 4.3 to 4.4.2 through Odin. rooted. with CWM Recovery.
tried probably 3 custom ROM that support 4.4.2 and end up on the Official leaked.Build 4.4.2 ( rooted)
the battery performance is driving me crazy.
on 4.3 stand By mode i used to loose 0.8 per hour now with the same setting same features turned on. i loose 2.3 percent per hour.
on 4.3 screen time with the lowest Brightness i lost 1 percent every 10 minutes. now i loose 3% with same brightness level. 3 percent every 10 minutes.
Android OS and Android System are always on top of screen in the battery Graph. i
media is also on top of the screen in the battery graph.
have tried a lot of solutions and factory reset with no luck at all. ( i have placed the device with Airplane mode with no SUCCESS )
installed a lot of battery analyzer apps did not have a clue who's eating all the Juice.....
any idea how to fix this??

No wakelocks in BBS?
Install Better Battery Stats. Leave the screen off for 1 hour and tell us what the top Kernel Wakelocks are.

Partial Wakelocks are usually caused by apps running in the foreground. There's usually not much you can do about that. If you are actually using the phone, battery will run out. What you need to find out is what happens when you are not using the phone.
Do this:
1) Charge the phone to 100%. Disconnect the cable.
2) Let the phone sit idle for 1-2 hours with screen off.
3) Get Kernel Wakelocks from Better Battery Stats.
Then you'll know what's eating your battery when you are not actually using the phone.
In my case, I get ril-fd, l2-hsic and wlan_rx_wake wakelocks the most. I know the causes, but I can't do anything about them without rooting.

I've noticed the first 10 percent (from 100 to 90) go away fast as hell. Use your phone as you would today, just make sure you have enough juice by the end of the day. Leave it as it is overnight and then post your screenshots.. You don't seem to have any wakelocks so your battery shouldn't be draining.. Mine is going like 1% for 8 hours or something, the problem starts when I turn me screen on lol!
I had this problem on my all my Samsung device
the only solution was to take out the battery for a few seconds
worked for me on
note 2 and 3
s4 9505 and 9500

i am loosing more than1.5% per hour where on stand by mode... everything is switched of.f im surprised there is no wakelocks showing... ill wait till the end of the day.
its been 4 hour since last charge and now im on 93%..
im assuming the drain is happening due to the bad reception where i am at.
how do you manage 1% per 8 hours that's Awesome (knock on wood) :laugh: .. is this with WIFI and Data on?
i don't understand ... how come i have no wakelock after screen off.. and my battery draining 1.5 % per hour on stand by mode.... and android Os always on top ?
BBM.
And I haven't done anything special, actually you have to do something to NOT get great battery life while idle. After a factory reset, nothing disabled (so G+, G search and all those wake cycles still present) with WiFi off and Mobile Data ON I lost the usual 1 to 2% per 8 hour sleep. The problem starts for me when I turn on my screen, not when it's turned off

What are the causes for wlan rx wake? 12hsic is related to mobile data i guess.

It's caused by broadcast packets sent by other devices in your network waking the phone up. The solution is to install a custom kernel that filters such packets.
Can someone please tell me why these 2 things are consuming so much of battery??
Although the screen on time is around 2 hours...
That's pretty bad screen on time. Normal use got me about 2h SOT at 70%. Check if you enabled sync or NFC.

sync is enabled, but nfc is not....
it has been since a few weeks, i don't know why!!
i remember watching movies on it for about 4-5 hours and battery left was about 50%
Disable sync. It takes up a lot of battery. If you can't disable, set sync interval longer or to manual.
will change the sync to off...and see if that has any significant change....thanks
No improvement even after disabling sync.
I noticed today a instant drop in battery percentage when I reboot the phone.
Also I found out in a thread about cupid showing the capacity as 2100 maH in some note 3...I found the same on mine...
Is it some calibration issue...??

First try to turn off the phone completely and turn it on again. Sometimes that may help.
Second, install Wakelock Detector to see which process eats your battery.

Not too ok, but average and acceptable.
Did you use Wakelock Detector app to check?
