[Q] HELP, battery reading problems - Fascinate Q&A, Help & Troubleshooting

couple weeks ago, i pulled my battery out when it was at 81% started it back right away and it was 45%, did it again today, it went from 71% down to 29%, my battery reading is tripping, I noticed. MY BATTERY IS HORRID, i lose 1% power per min on the lowest screen brightness display setting, could this have anything to do with this?
side note:
using my battery. battery stats says that my screen is causing 99% drainage.
my buddy battery: my screen is 80% drainage.
bad battery??? it still drains really quick with my buddy's battery, but DOES perform better. but not by much...
another thing, lol..... charging differs. sometimes it can charge like 10% every 10 minutes, and sometimes 30min for 10%.....its just weird. and my phone doesn't last me longer than 10 hours full charge, minimal use.

You may want to look at your battery health under the battery information menu.
Also to better understand and provide support we need to knock out a few things.
What is your current set up? ( rom,kernel, etc)
Have you done a battery calibration at all?
Have you run things like cpu spy to see what apps could be at fault?
All of this can give the community a better picture of what may be going on
Also I pull my battery alot because of testing and sleeps of death and I see very good battery life still. Atm 15 hours @ 72% and I am far from conservative.

kernel is the community TSM, battery still was wierd in stock rom, sc 2.9.2, and others.
battery health is good according to spare parts at 3850mv.
currently charging its been at 16% for 10 mins.....

Just FYI, you don't have to do a battery pull when you get SOD. Just hold the volume up and power buttons until you see the samsung logo, then let go. This is a hard reboot of your phone. That will save you battery a little bit as you won't be pulling it as much.

battery Never really hits 100% anymore

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.

Getting horrible battery life

I'm on Axura 2.2.7.2 and have horrible battery life no matter what battery I use.
For example, my battery percent is at 63% right now:
4h 48m 38s since unplugged
Display 90%
WiFi 5%
Cell Standby 3%
Phone idle :1%
The weird thing is that I don't really use it a lot either. I used it for maybe 20 minutes max. Talked on the phone for 5 minutes, made about 10 texts, and checked the time from my phone thats it.
Also, I'm using Zeam launcher, could that be the problem?
Please give me some tips on how to maximize my battery life.
You have to calibrate your battery. Download Battery Calibration from the market first, then kill your phone all to like 5%. Charge your phone all the way up to 100%
Then click on the calibrate button on the Battery Calibration app. You should be good after that. Make sure your unplug after calibrating and die the phone down again, and then charge is back to 100%
Sent from my Vibrant on Ultimate 2.2.1
please go to settings / about phone / battery use and post what is consuming most of your battery so we can help u better knowing what the problem is.
there are a lot of ways of improving battery. the best 4 me so far is a custom kernel that allows undervolting which helps a lot without affecting performance. underclocking if u want to go the extra mile, and lowering brightness helps too since our screens are battery hogs.

[Q] Is my battery defected?

Does this look normal to you?
Btw, everyone says that it take forever to charge, but how long exactly? It takes about 3 hours to charge my phone from 50% to 100%. Is it too short, or too long?
I use minimum brightness and running Unnamed 2.1.0
Where did your battery defect to? Those fricken commies.
Overall numbers don't really say a lot. You need to look at what might be causing excessive drain. Do a search for "better battery stats" here on XDA. It's essentally the pay version in the market. That will well you any "offending" programs that might be using up excessive battery time. 22 hrs on a single charge fricken awesome and you show more battery to go.
Yes it takes quite a long time to charge the battery. 3hrs from 50% might be a little long but not that far outside the posted norms. If you're connected to the computer via USB, it will take significantly longer than being plugged into the wall.
Use BBS to hunt wakelocks - you've got some unusually long awake times.
However, 54% drain in 22h with 1h37m of screen on time is not TOO bad.

I am using Unnamed 2.1, I believe it has BLN support. Is it a battery drainer? If so, how do I disable it? i dont see any BLN setting in Setting.
I installed BBS. Here are the screenshots.
Unless you enable BLN using the BLN Control app, it should not drain your battery.
71% deep sleep seems pretty poor, especially 9 hours of awake time with only 1h37m of screen on time.
it looks likely that you've got an app(s) gobbling up some of your battery. But i don't think your battery is defective at all. 22hrs and about half your battery left isn't too bad. You could certainly do some things to make it better, but the battery itself most likely isn't defective.

Battery draining within hours.

I have a extended battery. I usually get 2 days use on a charge. about a week ago I cannot make it thru a day. The battery is only about 6 weeks old. I tried another battery and same thing. I use task killer and app cleaner and have restarted several times. When I look in battery usage is shows the Android OS using 24% Display 26% and phone idle 24%. I did update all my app and this seemed to help just a little. Anyone have any suggestions before I return my extended battery or do a factory reset. tks in advance.
have you tried draining the phone completely till it shuts off, then plugging it in and letting it charge to 100% with the phone powered down?
Battery instructions say NOT to every let battery drain to 0. So not sure I should try that.

That is about the life that I get on mine on a bad day. Now that you have had the phone for a while, more than likely, your battery has not changed but you have installed more apps which are draining you battery even faster. You shouldn't use task killers either, they screw with the roms built in memory management. However, if you must, then use "Task Manager" the built in stock task manager to end apps. Also i agree that you should completely discharge your battery and then let it recharge completely without turning it on and without using it.
PS: You have a nice avatar. Conservative til i die

This is not true. The phone has its own power management. When you reach 0%, the battery has still at least 3100mV (on mine it's more than 3200mV).
Li-On and Li-Pol batteries are designed to operate between 4300 and 3000 mV when they reach more or less, than they are damaging.
So you can charge and discharge your phone everyday between 100 and 0%, without any battery damage.
Other thing is Android power management, every time you wipe battery stats or restore backup, or you spend some time in recovery, Android doesn't know, how much capacity is remaining and you need to make more charging cycles, to teach it again and get full capacity from battery. I still don't understand this kind of management in Android.
I've tried all the battery stuff. No dice still discharging fairly quick. In the Battery Usage section It still showing Android OS using around 39 to 40% usage all the time. I have done a full factory reset on the phone 2 days ago and still same.
I noticed, you are using the task killer, stop using it, you have probably loop of killing and starting of some services. Task killer kills, android starts, again and again...
I have uninstalled task killer restarted the phone and still got the high Android OS usage showing.
You won't notice any difference immediately, make one discharge, charge and discharge cycle and you'll see.
Do NOT discharge the battery completely. Over discharging Lithium ion batteries can be harmful to them. Here's a great article going into probably a little too much detail but it gets the point across: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
As far as your problem goes it may be an issue with the phone itself I've seen a couple photons that needed to be exchanged due to issues that sound similar to yours. If it's doing the same thing on a different battery I'd take your phone into a sprint repair center, you could also try a factory reset if you have not already done so. If your only seeing this behavior with your current battery then I would return it or request a warranty replacement.

Yes, there is an additional reserve that the Smart chip will protect by turning off the battery once it reaches the "0% mark". The Smart chip will also continue to drain the battery further past the 0% mark eating into this battery reserve. Now one full discharge like this probably would not hurt the battery as long as the battery is recharge within a reasonable amount of time. However it certainly does nothing to benefit the battery health whatsoever and it is never recommended to let a battery fully discharge. There are some practices of only charging the battery to 75%-80% that can improve battery life, but individual run time will be sacrificed. My recommendation is if the battery is under 65% than to charge the battery if it is possible to do so.
After doing a factory reset the same problem remained. Sprint exchanged the phone for a new photon. Put my extended battery back in and so far no problems at all with the exception of not being able to join my contacts with my FB contacts.
I have been discharging my Photon and previous phones to 0-5% at least 3 times for a week and did not find any difference in capacity, compared with the new battery. Lasts from the morning to the evening. If I should charge it on 65%, then the phone would be unusable for me.
Like Schale said it could be an actual phone issue, but i highly doubt it. I would try some things before assuming its a problem with your phone. Do this... Also this assumes you are unlocked or at least rooted.
1: Factory reset so to start fresh with no crap applications (task killer apps do more harm than good, as do most battery saver apps)
2: Drain battery till the phone shuts itself off (Dude what right about it reserving a certain amount of juice to not cause damage)
3: Charge to 100% (Dont use the phone during this time.)
4: Use a battery calibrator app (rooted) or recovery (unlocked) to wipe the battery stats.
5: Drain power as fast as possible till phone shuts off
6: Charge to 100% (Again, dont use the phone during this time.)
You can now use the phone how you normally would. If you don't notice a drastic increase in battery after discharging and recharging three or four times over the next few days, I would be comfortable in assuming it's a phone problem. Good luck!

[Guide]Battery Problems- Solved & Battery Saving Tips[Newbie Friendly]

I have seen lots of threads about people complaining about very poor battery life after flashing roms. Sometimes battery charges to 100% quickly and discharges very quickly.
So, these are the solutions. These solutions are IN ORDER. If the first one has no effect, then try the next one. If the second one doesn't work, then try the third one.
Now-
1) Try reflashing your ROM.
2) If reflashing your current ROM doesn't work, that probably means the ROM itself has poor battery life and you should change it. Stock ROM's have the best battery life.
3) If you are on stock ROM and still having problems, switch off your phone, take off the back cover and remove the battery. If the battery is swollen or the shaped weirdly, this means your battery is dead and almost useless. You need to buy a new one.
I recommend buying only stock batteries manufactured by Samsung because other batteries can be fake, incompatible, or just used batteries sold to you. Don't buy anything else unless you're absolutely sure of what you're doing.
Hopefully I helped.

General tips for saving your battery-
1) Switch off mobile data whenever you're not using the internet.
2) Change your wifi sleep policy. This can be done by going to wifi settings, pressing menu button and then select advanced.
You can change your sleep policy so that your wifi sleeps when the screen is off.
3) Decrease your brightness! Your screen is responsible for most of the battery drain. Increase your brightness only when you are in bright sunlight or when you're watching videos etc.
4) Switch off GPS. Keeping it on all the time also drains a lot of battery.
5) There is an app called 'Greenify' which hibernates the apps running in the background. This app has increased my battery life. Here a link https://play.google.com/store/apps/...e=google&utm_medium=organic&utm_term=greenify
6) Don't charge your phone when it's at 70%. Wait till it is between 20-30% and then charge it continuously till it reaches 100%.
7) Let your battery completely discharge once every month.
8) Don't use task killers. They use more battery life than they save.
9) NEVER charge your phone overnight. Your phone takes only about 4 hours to charge. Overcharging reduces your battery life
10) If you use a Bluetooth headset, switch off Bluetooth whenever not in use.
11) Using setCPU profiles. This is one of the most effective ways of saving battery. You all know about overclocking, but do you know about underclocking or undervolting? Using profiles, You decrease the clock speed of your CPU when certain conditions are met. These profiles can be on the basis of time, screen off/on, battery etc. So when my screen is off, it automatically reduces the clockspeed which saves battery

Using these tips, I have gotten almost 2 days of battery life on stock Roms and a whole day of battery life on custom roms like CM10.1 and CM7
If you have your own battery saving tips, please share and help expand this list.

Are you sure about these? Because I've read that phones only take how much ever charge that they need, so charging overnight isn't a problem. And i've also heard that letting the battery charge fall below 40% actually reduces the life over time.

Yes, I am sure and it is something I have verified.
Overcharging kills the battery.
I saw a video once of an evo 3d. The battery almost completely died after it was charged for 3 days
And you should always charge only when your battery is low.
This will ensure longer battery life

Normally, when the battery is fully charged, the chip that controls the charging process reduce the current exponentially to 0: this avoid the overcharging.
I think all smartphones have the charging chip control integrated (an USB cable is simply a power source, not a battery charger), so I hope we can leave the phones on charge all the night without any problem. I do that always and never had problems.

Quoting Dianne Hacborn(Android Framework Engineer):
"Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away."
Its just a myth mate..
And also, it's a myth that you should let ur phone charge reach 10% or get fully discharged before charging. This actually leads to decrease in the battery life over time.

But I have never mentioned that clearing battery stats increases battery life!
Tips to increase battery life are in the 2nd post. I simply said that if you clear your battery stats, UI will show you battery which is more accurate to the actual battery level.
Why are you arguing over something I never said?

And also, it's a myth that you should let ur phone charge reach 10% or get fully discharged before charging. This actually leads to decrease in the battery life over time.

Think of your battery as a person working out and charging is like taking rest. If the person's ability is to do 100 reps yet he takes rest after only 60 reps and keeps doing that continuously, he won't be able to do 100 reps after a few weeks!
Look at the logic mate.

I am not arguing :/
I am just trying to help make your guide more Informative. Read what I have put in bold letters mate. It doesn't affect the battery level shown to you

Thanks for tips
You misunderstood me :'D
Clearing battery stats does not:
Affect battery life
Affect the battery level displayed to you
The only thing it does is, it wipes the history of battery consumption by each app. I am talking about the battery consumption by each app shown to you in Settings>About phone. If you clear the battery stats.bin file, the only thing that geta erased is this

This! Anything about wiping battery stats is not a myth anymore, so please stop misleading people,
Also "6) Don't charge your phone when it's at 40%. Wait till is below 10% and then charge it continuously till it reaches 100%."
Not true! Charging your battery around 50% is the most efficient way to keep lithium battery alive longer. A discharge once a month is also recommended.
