Ever since I rooted my fiances and my phone his battery life is so much better then mine.
Mine right now is at 92% and has 17hrs 30mins
His is at 88% and has 24hrs 48mins.
Is there any way that I can improve mine without having to buy a new battery?
We are both using kaos v39.
Thank you for any help.

Have you tried calibrating the battery?

The battery % also isn't necessary accurate.
The phone uses a calculation of voltage (as closely as it can), temperature, and activity, to determine the %. Largely, the figure is just based on voltage.
Sometimes, when your phone is charging, it can say 83%, but be at a solid 4200mV (4.2 volts). It's probably not going to charge any further. If you power the phone off, the light will probably turn green (showing you that it's charged). Then if you boot it back up, the battery % might read 100%.
Is it 83%? Is it 100%? Clearly, in the 2 minutes it took you to turn your phone off and on, it didn't gain 17% battery.
The difference between 88% and 92% could be temperature, voltage of the particular battery at the moment, who just used their phone more in the past 2 minutes before checking, and (due to all the variables) practically 'dumb luck'.
What you really will see is if you let them go for a very very long time (until they get to 0% and auto-shut off), you'll find that whoever had their screen on more often (maybe whoever does more texting), or whoever has more 3g internet doing things in the background (if one of you has an email app that checks email every 10+ minutes, keeping the phone awake, and moving data), or whoever works in a workplace with worse reception (that will eat battery very quickly, as the phone uses battery to get 'louder' so that the cell phone tower can 'see' it), will have their phone hit 0% more quickly.
The difference between 88% and 92% may actually be nothing. It's just your phone's 'guess' at how much battery is left. His phone's 'guess' is different, because the variables going into the calculation are totally different for a handful of minor reasons.
I wouldn't sweat it.
If yours hits 10% when his is still at 40 or 50%, with similar usage, yeah, that's something to pay attention to.
But the battery % isn't THAT accurate, to even sweat 4%.
I promise.

Alot of widgets can also change your battery life as well. Especially things like Facebook, location based weather, latitude, etc. Ones that are always updating and using data or gps.

Thank you that makes me feel a lot better. I was starting to think something was wrong with my phone but your explanation tells me that nothing is wrong. =) Thank you for taking the time and patience to explain it to me. I didnt realize how little it could take to eat the battery down.
Ok so Here's the deal
When I flash a rom I charge the phone till it hits 100%. I then reset the battery stats and go on about my day. With in a few minutes of being off the charger my battery has now dropped down to about 96 %. I do realize that batteries do not stay at 100% but this is crazy. I've only deep cycled my battery once for fear that it may damage my battery.
I Am using Teamwhiskeys ultra awesome bionix-v rom with ttabals oc kernal. I know I am to expect a slightly more rapid drain but this is crazy. I have even tried to lower the vcore and I slowed down the cpu to 800mhz. It still drains just as fast.
The odd thing to me is If i turn my phone off and let it fully charge to 100 percent reset stats then turn on phone It will show full for a minute then drop down to to 96 or 95 percent.
I personally think my battery is damaged but spare parts shows that it is ok.
So i am rather confused by this .
I know I should probably use the stock kernal but it seems like its just as bad with that.
I have looked at the threads about battery life and I am not expecting it to be amazing just hoping it will be ok!
Tell me what ya think !
mt battery play tricks on me too when my phone doesent see that im lookin at it it shows 90 when i look at it and phone notice it bounces to 85 like it hates me , lol but dont take my words for it P
Spare parts would show that too. I remember when I had my G1 spare parts would tell me it was fine. But a 3 hour full battery doesn't seem fine does it? Id suggest getting it replaced.

Ill probably nurse it... but I am having major ocd type problems about it.
I cannot stress this part enough, so I'm putting at the top, do not do the following often, as it can have a negative effect on Li batteries if done too much.
You want to try what is known as a bump charge. With your phone off, charge to 100 percent. You will see the green battery icon with "100" on it once it reaches full. Unplug from the charger for a minute, then plug it back in, phone still off, and let it reach 100 again. If you want you can do this a third time, do keep in mind, bump charging too much or with any type of frequency can have negative effects on your battery, but doing it once in a great great while helps with with what you are experiencing.
thanks Br1cK'd and those who replied.
I have tried the bump charging method. I am affraid that my efforts to repair my battery are causing it more harm than good.
ok i just restored bionix v and had it charge to 100 percent
spare parts says
battery level 100
battery scale 100
battery health good
battery voltage says 4243mv
battery temp 30.0

There is one thing you are messing up. If you flash your phone on a 100% charge then you DO NOT need to wipe battery stats. You only have to wipe battery stats if you flash when your battery is not at 100%!

It's not out of the ordinary for a battery indicator to show a few percent drop rather quickly on a LiIon battery. Secondly you should take a battery indicator with a rather large grain of salt. Expecting precision in single digit percentages from the indicator is unrealistic and nearly impossible to rely on given the nature of discharge of a battery. Batteries do not charge or discharge in a linear manner, and people do not use battery powered devices in a linear way either.
It is a visual guide, not a precise and accurate indicator. Many custom roms have a percent accurate indicator, but don't mistake this with being dead-on accurate. It is merely an attempt to make it a BETTER visual GUIDE.
To evaluate battery life properly is moderately time consuming, though rather obvious. Use your device as you would normally. Pay attention to how long it stays charged. If it's not staying alive for a reasonable amount of time (12-24 hours depending on what you are doing of course), then it's time to dig deeper. Apps that wake up and generate unnecessary Partial Wake usage, a lot of background application syncing or apps with short sync intervals, being in an area with poor data/voice signal....these are the usual culprits.
Apart from situations where people are playing around with experimental kernels (i9000 derived kernels tend to vampirically drain battery a few percent an hour regardless), the things that drain your battery are....things that "use" your phone. The more you do (and the more your phone is doing with your permission while it's in your pocket) the less battery you will have.
In the end it comes down to asking yourself some questions. Do you need to automatically update facebook, myspace, twitter feeds constantly when you can manually update them and be inconvenienced by a 10-20 second wait? Do you really need to update 35 rss feeds in Google Reader?
Most people's power related issues come down to three things.
1). Apps that wake up without your knowledge and waste battery for no good reason (I'm looking at you Media Hub!!)
2).All those other apps and widgets that are updating inside your pocket when your not reading, watching, or caring about them.
3). Being in an area with poor data/voice signal, forcing your phone to "hunt" excessively for a better connection.
Apps that wake up and do god knows what without your knowledge can either be removed, disabled, or frozen. Examining partial wake usage can give you insight into what may be going on in that scenario. Apps can be "Frozen" with Titanium Backup Pro (paid) or App Freezer (free).
The other part that is within your control are all the apps/widgets you actively use, and your decisions about how often (or even if) they update themselves.
I've bought a new legit/official (has holo, serials etc.) Atrix battery.
Charged it to 100%.
During usage, its draining literally 10% an hour with very light usage (several minutes an hour). In short its draining at three times the speed of my 1 year old battery.
I've tried wiping battery stats but that didn't work.
Any ideas, or is the stats just buggered and I just gotta run it in? (ie it will go to zero then sit on zero for 5-6 hours lol)
note I've gone back to my original battery in meantime rofl
EDIT: The actual problem is that the batt is reporting much less capacity than it actually has
|The new battery is great capacity wise lasts till midnight
However the stats are still totally screwed, it will say 1% by midday, then hum along until midnight fixed at 1% (I dunno exactly how long for as I can't take the risk of leaving it off at night then its dead and I don't wake up for work in morning). |
Could just be a bad battery. Considering the old works fine that's probably the problem.

I have a similar problem with the original battery that came with phone it drains the charge quickly to 1% and on one 1% it gives a battery life of more time than the time it took to discharge from 100%.i was thinking of buying a new battery but now i am confused that what should i look before buying the battery to get a battery that can show me the exact charge on the indicator.
I have tried all tutorial of calibration used different roms and kernels but nothing seems to solve the issue.
well I might try that then, just let it run to zero see how long it lasts then see whether the stats come good over time
OK help needed.
The new battery is great capacity wise, lasts from morning to bedtime with >2 hours of bluetooth music, 30 mins calls, a ton of texts.
However the stats are still totally screwed, it will say 1% by midday, then hum along until midnight fixed at 1% (I dunno exactly how long for as I can't take the risk of leaving it off at night then its dead and I don't wake up for work in morning).
Aside from wiping stats which I have tried, is there anythnig else I can do?
I really want to use it, like I said real life capacity is great, but if its always giong to be reporting 1% its a bit dicey not knowing how much batt you really have left...
same issue with my spare battery not sure wtf is going on
When I have battery stat problems the following has always fixed it:
1) leave phone on until it dies
2) take back off phone and plug into wall charger
3) after batt symbol shows 100% (without unplugging or turning off the phone) remove the battery. After a minute or so battery symbol will have question mark
4) put battery back in and leave it for at least 2 hours (seems like I have had to press the switch sometimes but you don't want the phone to reboot or you will have to start all over)
5) reboot into CWM and wipe the battery stats
6) reboot and it should be good to go
Anyone else found a fix to this yet?
I'm now running ICS (turl build) issue is still there.
Steps taken to resolve
- discharge to zero
- charge to max
- wipe stats
still there.
The weird thing is that the actual capacity is fine, it can last all day no worries, just from midday onwards it thinks its 1% so has annoying LED flashing at you, also you have no idea how much batt it actually has.
Edit: I just realised your suggestion above has extra step (take batt out of connected atrix then insert again). I guess I'll have to drain it again and do it overnight... gah

Nothing will work i have tried almost every tutorial. Recently i found out the phone is showing the the full capacity of battery only 500 that's why i think we will have to change that with the actual voltage to get a accurate battery indicator.What's ur battery full charge design check if from the root exploler
/sys/devices/platform/cpap_battery/power_supply/battery
My phone uevent is showing this
Powersupply-capacity=5
Powersupply-voltage-now=3836000
Powersupply-temp=260
Powersupply-charge-fill-design=500
Powersupply-charge-counter=1

I'll try the insert empty bat into already connected phone, charge to 100% remaining off, repeat trick overnight, then report back.
FWIW on my 'good' battery which is 1 year old ROFL it says 1880
not sure how changing it would help though or is even possible?. It must be dynamically reported somehow as my good battery gives me a 'good' stat.
I use battery calibration and it worked, have it

I'm guapurrin
the battery is charging calibration if you have to load it to calibrate

How much is ur other battery showing.I have tried different ways but was not able to change values.
500 same as you! second drain and calibrate did nothing
Maybe theres a faulty batch of batteries and we both got one
Can people PLEASE stop telling us to calibrate we've BOTH DONE THAT MANY TIMES NOW. The problem is that the capacity of the battery is being reported as 500mah not 1930 or whatever its supposed to be. THe actual running time of the battery is fantastic, just thinks its at 0 all the time lol
/sys/devices/platform/cpap_battery/power_supply/battery
Powersupply-charge-fill-design=500 - should be ~1900mah

And I don't even view anything in 3D, on leedroid, and music and stuff drains the battery quick
Normal?
People often get confused by battery use percentages... It took me a while too, but maybe this can help...
Say you're sitting at 90% left of your battery... that means 10% was drained. Looking at battery use only refers to that 10%, not the whole 100%.
So... if the screen reads 74% and your battery is sitting at 90%, what it is telling you is 74% OF the 10% used was from the screen.
And no matter what, any phone or tablet's screen is going to use the majority of the battery unless it's e-ink (even then it's a good possibility). I wouldn't stress to much about it. You can reduce this by using autobrightness or lowering the brightness than it is.
If you're frustrated with the battery in general, turn off best wifi performance and turn off always on data.
Also, leedroid has a terrible battery life.
After my stock battery started dying and not holding the charge anymore I bought two new aftermarket batteries (2300mAh) everything went fantastic for some time, then from one day to the other the battery I use daily started draining crazy (even 2% at time) I tried a lot of roms with no luck. Bad battery you say, here is the weird fact, the other battery which used maximum 4-5 times at month keeping it at half-charge, has the EXACT same drain that the other has. Is it possibile that something in the phone has gone nuts and is indicating wrong values? I also ran a full charge-discharge cycle preventing the low battery shutdown through xposed, and it shutdown some minutes after hitting 0%, at full charge indicates 4.300mV is it correct, isn't it?
Also using the *#0228# code (I can't recall now if it's correct) the charge level drops a lot like 30-50% and I noticed that the phone later stays at that % for quite a bit and also the heat from the battery draining stops and the phone stays very cool also while gaming, until it starts draining again
No one?
You can look at the simple battery-statistics in setting to find abnormal consumption by an app.
Otherwise buy a battery from Samsung's e-store: I bought several 'original' batteries (not for S3) from Amazon and mentioned too early wear after 1/2 year.
Replacement batteries are a waste of money. I had 2. 1 bloated and the other dies in a few minutes. Upgraded my phone instead.
I wish I stole my HTC M9.
