Hi all,
Why does my battery drains faster? I checked the battery used and "Cell Standby is 70%" could this be the reason of it?
Currently using Custom Rom OptimusXrom v1.1..
Help please..
Download Spare Parts and monitor with that.
Hi badeaioan, I'll check it later.. Thanks!
still my battery drains faster, cell radio is almost 70%.. can somebody help me here?
Install Watchdog. That monitors your app's CPU usage and warns you if it goes above it's threshold.
Also, you can try wiping your battery stats.
already wiped the battery stats... nothings happens.. still the Cell Standby is 70%.. how about yours?
20%.
Do you have SetCPU installed? Try setting a profile that lowers your maximum frequency down to 245MHz when the screen is off.
EDIT: Also, you have to note that the battery info in the about menu is not live information. It updates slowly (once in a while).
yes i have installed SetCPU. I'll try to make a profile, and monitor it.. I'll post an update tom. Thanks.. I'm planning to try UbuntuDroid if this wont work.. I already tried, amber home, prime and currently using optimus x.
Cell standby is also at 75% for me and the battery has juice for 2 days. So don't worry about it.
All the p500 phones show that cell standby is the biggest conssumer (i know 4 guys with same phone). For example on a Galaxy S the screen eats all the battery.
I figured it out!
The battery usage info menu does will not show you whether your battery is draining faster or not.
Here's how it works:
Suppose I have 5 apps: a, b, c, d, and e. Let's say cell standy is app letter a. Overall, battery usage is 100%, right? Assuming everything consumes power at the same rate, app a gets 20%.
If you have cell standby consuming 70% power, everything else consumes 30% power.
Confirm this by visiting your battery info menu. Also, you only have a problem when what's consuming more is an unnecesary app. As for cell standby, I wouldn't worry about it.
Do you have a screenshot of yours?
No I don't have any screen shots, so you mean it's ok that my cell standby is 70% sometimes more... ? My officemate's Samsung galaxy s cell standby is something like 3% - 10%.. that's why I'm thinking that cell standby is the reason why my battery drains faster?
What apps do you have there by the way? I'm guessing there are a few, or many but using only about 1-3%
If you ask me, no. Out of the 100% battery use, cell standby is using 70% of that. 30% goes to everything else.
How you use that 100%, though, is a different story.
hmm.. I see... well I guess I'll try different rom... what rom are you using? I noticed, before I go to sleep,for example I check the battery 90-95% when I woke up and check it again, the battery goes down to 50%... I wonder why... standby.. and drains that fast?

Light. Wow, that's a huge difference Try another ROM. See if that solves the problem.
Yep, that's what I'm planning to do.. I hope it'll solve my problem.. hehehe I'm just waiting for my phone to finish charging.. I'll post an update tomorrow.. Thanks again kpbotbot.. how the rom you're using? how's the battery life?
Feels like the stock ROM (which is why I like it). The only difference is that stuff under the hood are tweaked, optimized, and the like. Plus the useless apps are removed. Battery life is... adequate I can go about a day and get about 60%. I don't know how long 100% will last since I always recharge.
PS - In case you're wondering why I reply so fast, it's because I have nothing to do at home since I was advised to rest for at least a month after release from the hospital xD
Try battery saving apps like juice defender.
Im using juice defender with ultimate juice and use its mobile data toggle widget to switch off my internet when I dnt use it..
hmmm..actually I was.. hahahaha.. now I know why you reply so fast.. Thanks dude.. get well soon..
40% it's a normal value?
I don't know why your battery drains so fast (50% over night is tooo much) but right now for example in "battery use" menu I have:
13h 50m since unplugged
Cell standby 78%
Android system 13%
Display 5%
Voice calls 4%
Android OS 2%
I think this is normal.
I have the stock 4.5.9 gingerbread update on my AT&T ATRIX. However I am observing a terrible battery life. There are too many solutions in the forum to follow. Can someone direct me to the appropriate one? I am rooted and unlocked. I used the unlocked 4.5.9 sbf for upgrading from from Froyo to gingerbread 2.3.4
Sent from my MB860 using XDA App
there;s a lot of solutions because poor battery life can be cause by many things, you have to find out what is draining your battery. try calibrating first let it drain until your phone turns off and then if you have cwm install then wipe batterystats and then a full uninterrupted charge
Try setting profiles in SetCPU and freezing apps with TitaniumBackup. Theres a topic for each of these two solutions.
battery stats 6h 3m 29s on battery (now left with 10% of battery)
Display 49%
Phone Idle 22%
Cell standby 6%
Android system 5%
Launcherpro 3%
xda 3%
Android OS 3%
this is just terrible .. i never had such battery life with Froyo. i dont understand what might be the problem. Meanwhile i will try to calibrate my battery.

Calibrate your battery.
Then freeze your bloat.
Problem solved.
dont forget you might also being playing with your phone a lot more trying to see all the new stuff in the update. Thus causing more battery drain.

There are some strange things happening with the battery. I let my battery discharge completely to the point where phone shuts down. Then I plugged in to charger, waited for 2-3 minutes so that I can start the phone. Started the phone and saw 50% battery. Don't know what's going on.
I was told by an admin from another site that most of the battery programs do not work with ova ginbread. You go to settings/about/status and observe the battery. I do no I was also getting flaky results with 2 of the battery programs.

That's a GB bug... there's a battery fix in the development section to flash which deals with the reboot battery jumping. (turn off phone at 50%, turn on phone and it says 70%)
I am having problems with my Atrix too. With my usage, I used to be able to get almost 3 days of battery life. Now it hardly lasts a day. I have checked pretty much all settings (sync, sleep) and all seems fine as far as I'm concerned. So I am having hard time trying to find what is causing this. The only suspect I have right now is wifi. I don't think wifi is sleeping even though I've selected "When screen turns off" in the sleep policy.
Hi,
I have been facing these two weird issues:
1. Sudden drop in battery percentage: I have found that this occurs only when i reboot my phone (not every time though). So when the phone restarts, the battery is down by 20-30% or sometimes even more. And its not a one time issue. I have seen it happen at least 3-4 times in the last 5 months.
2. Sometimes when I am not charging the phone, the battery % keeps increasing slowly. This has been happening lately since the time I have rooted and flashed my phone. 2-3 occurrences that i know. I don't recall seeing this when I was on stock. Just this morning I plugged my phone off the charger at 52% and I left for work. And right now at this moment when I am writing this, the phone is at 58% charge!!
Just FYI.. I calibrate the battery every time I flash a new ROM.
Thanks,
Sam

I think that Entropy can answer this better but I'll still give a try.
[Q] Why these sudden battery level drops after reboot?
[A] The sudden battery drops is a known 'issue'. It's not a bug, it's the way the fuel gauges are designed for i777.
[Q] How to avoid these sudden battery level drops?
[A] Try not to reboot while it's on battery if the battery level is <50%. In that case, if you need to, make sure that the phone is plugged in for charging and then do the reboot. That should prevent those random battery level drops.
[Q] Will using battery calibration apps help?
[A] No, the way the i777 fuel gauges are designed, there is no need of battery calibration apps. The best way to get accurate battery level readings is to allow the battery to go through full 100%->0% battery discharge cycles for atleast 2-3 times. After each full discharge remove the battery, keep it out for a minute or two and reinsert, recharge the phone.
PS: The weird battery charges that violate E=MC^2 law might have to do with your battery not having been through proper discharge cycles (and thus not having been properly calibrated) after flashing a new ROM.
@Mod These questions are asked many times, how about adding them to FAQs (not sure if that will help though )
@Entropy Please review this post.
Pretty close.
Calibration does nothing on our device - the fuel gauge is designed so that it will always converge towards truth instead of diverging. Also, the "wipe battery stats" method of "calibration" has been proven to do NOTHING on ANY device whatsoever - https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT - The "charge battery to full" and "discharge/recharge" battery are valid tactics on some devices, but NOT any Galaxy S or S II device (maybe the ****rocket and T989, but not the I9100 or I777.) - There's a slight chance this may change with ICS on the I9100/I777 but not likely.
The advantage of this is that it never needs funky calibration cycles other than "just wait"
The disadvantage is that the gauge will get thrown off in a few limited corner cases - and the "two" issues described are one widely documented one. The gauge gets confused and falseley reports low by heavily battery load immediately following a reset, and takes a few hours to converge back to normality (during which the estimate creeps upward, because it was lower than reality initially).
And yeah this should probably be in the FAQ. I'll work on submitting it this weekend.
Thanks guys..
So looks like the sudden battery drop issue can only be prevented but not fixed!

It's pretty much the characteristics of putting a battery under load and using voltage to dictate battery level. when you draw a lot of current from a battery you'll usually see the voltage level drop, more so as the battery is discharged. Booting up the phone consumes quite a bit of power, substantially more than the device at idle. So upon start up the device reads the voltage level to dictate battery level. Since the device is under a relatively high power draw, it sees a lower voltage than would be at idle. It in return thinks the battery is lower than it actually is, or would read under idle load. the battery level will actually creep back up slowly because it will read a higher voltage, than it did upon start up.
The only way i could think of to get a more accurate reading would be to delay the initial voltage reading/recording upon start up, or to use the last voltage reading to help dictate the battery level. But i have no idea if that's even possible, or if it would conflict with some sort of other operation.
I just don't get it!!!!!!!
I was playing multiplayer in bombsquad today morning wid my friend .My battery was @ 86% at that time
suddenly my battery came down to 15% then in the other moment it went to0% and mt phone got shut down. I plugged my phone in charge through the power bank and rebooted it and I saw my phone was @52 % I started using my phone and it again suddenly sut down this time without even a battery low message
it's been happening regularly wid my phone since then.
What could be the reason? And what can I do to make it right?

This is the wrong forum. Even though the thread is about a problem similar to yours, we don't know anything about your phone.
If you have a removable battery, you might try purchasing a new battery, but that's just a guess.
The forums for you phone are here.
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.

root your photon (if not already rooted) and download battery calibration from market, also after rooting go to android development and download th3bill's extended battery mod

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!
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.

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..

I am aware of what you are saying and I fully agree.
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.
