[Q] Charging and Multi-tasking, is this a no-no? - Galaxy S II Q&A, Help & Troubleshooting

hey guys - need an answer to solve my neverending search to this problem
i'm trying to determine the best way to get as much battery power out of my SGSII and i've been experimenting between a SGSII and a Motorola Photon 4G. both phones are running a ICS-AOKP rom, same CPU clock settings, both on "conservative" governor, and both on power save mode..
the only significant difference is with the battery and the kernel, while the photon is running with a stock 1700Mah battery and stock jokersax CM9 kernel while the SGSII had an 2000Mah Extended battery with Siyah 3.0 (with "battery" kernel tweek on)
at the start of the experiment the SGSII had 73% power while the Photon had 48% - i plugged in both phones to the wall and ran a game of order and chaos on both for about an hour and then checked back on the battery power.. the SGSII had drained from 73% to 45% while the the photon 4G had actually charged from 48% to 62%
i've tried a similar experiment with not only AOKP but also CM7, CM9 and MiUi and MiUi V4 and both yield similar results
now my question - if both phones are using the same rom with the same settings practically speaking, with the SGSII being slightly more optimized towards battery performance, why is it that the SGSII's battery will still drain while the photon 4G's battery will still charge?

Wow, i haven't had battery drain like this, give it like 4 battery charges then you'll see whether you still have this problem or not
I can normally get near enough 2 days battery life with medium usage. I'm using the stick battery MIUI GB

wow dude, are u using the stock battery or an extended?
always calibrating ma battery everytime it gets to 100% and it doesnt seem to help much -
Id love if someone else attempted the test by plugging in the phone and having wifi on + run a quick game to see if your results are the same as mine.. the typical response i get from others i've shared my result with is "duh - the battery will drain if ur playing a game while charging, all devices do it" but i have to ask "then why is it that this doesnt happen to the photon 4G?" i remember going on the samsung thread and someone mentioned that the board is set to absorb a charge that is less than how much the Chipset consumes

[Q] Telus fascinate serious battery drain HELP!!!!!

Ive noticed serious battery drain since I first bought this fascinate from telus. On 2.1it lasted around 11 hours. Since upgrading to 2.2 leak, id say 8 hoirs max with only approx 1 hour of uusage and the rest on standby. I turned of sync, auto brightnrss and turned brightndss as.low as possible. I make sure no apps r running in the background. Yet it still dies superfast. Is this a issue with my battery thr phone itself or firmware or kernal. Its been a week of trying to find the problem so any help would b greatly appreciated. At tgis time im running 2.2 leak with all the files it came with and no root. Thx in advNce
And hour and 12 minutes with about 30 min of internwt surfing and im down to 80 percent WTF
I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...

sounds about average for a fascinate....
I'm on telus as well and also have terrible battery life, I've found no fix other than completely turning off Data using the toggle when holding the power button. Flashing a new rom might fix this but I've been to scared to since I bricked a phone trying it the first time. Hopefully when/if ever we get a 2.3 update it fixes this
Does anyone know where one can get an extended battery for this? I picked one up but it's for the friggin Verizon US version, and the battery cover isn't compatible, even though the battery fits(camera doesn't align, speaker's not even close).
Seriously, the American counterpart's accessories have been my biggest frustration with this phone, next to battery life...
Thought I'd give this a bump. The battery life on this Telus Fascinate 4G is truly disappointing and jumping through hoops trying to find and kill apps and services with and without utilities is wasting far too much of my time.
Anybody get a good handle on this?
Bump for same problem.
Samsung Fascinate SCH-i500 Verizon
Running unmodified and unrooted. The phone itself works perfect. No problems other than the phone seriously eats battery. Yes the battery is still good and nothing wrong with it. Plugged in it charges super slowly. And the screen itself takes more than it provides. So i did the following.
A. Changed battery to a known working one.
B. Check with car charger and a home charger. As well as official samsung charger.
C. Gave a ROM a try. Running Dirty Unicorn. Lowered cpu to 800 max and 100 min.
D. Turned display to 50% Brightness.
My only try now is to try a different kernel or something. Im also thinking that the display itself is the culprit somehow eating to much voltage.
Or the gpu. The phones operating temps are good.
I have another post here http://forum.xda-developers.com/showthread.php?t=2430393 relating to where i have a USB problem and need help figuring it out. There has not been any replies. So i am taking upon myself to learn more. Ive worked with 3 Droid Milestones. Hopefully these two i500s will not be to hard. I need help on this new i500 to see if its not the motherboard. The charging port is on the motherboard and if this replacement eats batteries , then the point would be mute to use it for a working USB. A conundrum.
Do i try a different kernel or somthing else. Whats my next step.. Please help.

what else do you have running?
what is the battery life overall usage? and screen usage hours?
screen is always gonna be the highest consumer of your battery
50% still pretty high unless you are out in sunlight, I keep mine between 0 and 30 % unless in sunlight
you can try running the greenify app from playstore.
what king of life are you expecting to get? anywhere between 6hrs to 24 hours total phone battery life is about average depending on how heavy user or how much in standby mode.

Its defiantly got something wrong as even though it says 56% if I unplug it, it will die in about 10 min. Even with a fully charged battery it does the same. Yes i also waited until 100% and wiped batt stats and at 3% left wiped stats. Screen is in standby

I had installed the program and it didn't really show anything abnormal. Although after installing the Bat Meter, when i shutdown it killed the phone till i ODIN. So tried on the other phone as well. Same thing. Install it and compared notes. Reboot phone and had to ODIN. So maybe bad app? Well whatever. I didn't see anything unusual. Although I did notice something strange about the phone that's bad with charging. I already eliminated the battery as the problem as well as charger. But the phone that is eating battery faster than it can charge, it gets warmer at idle than the other phone. It charged just super super tiny faster than the battery eats using just idle display on lock-screen. As well this phone also with a fully charged battery will read 100% But after about 21 minutes of poweramp at 33% volume on headphones will read about 52%. Then sitting rest at idle no display from 52% down to about 14% popup around another 5 min. Then completely dead in about 3 minutes. And the phone is pretty warm. Today it was ambient temp of around 87* outside and sitting in shade and it was hot enough that it wasn't comfortable on my cheek for more than 20 seconds. Half the time the temps are normal. Now remember I'm not running overclock and actually under clocked to 800. Ive tried 3 different roms with diff kernels and same. Could it possibly be a bad heat-sink? And the extra heat is killing battery?
[Q] Battery Drain
I recently was given a Fascinate and am having similar problems. I was told the phone had a bad battery, so I ordered a replacement. Once I got the new battery in, I flashed the phone with the Carbon ROM [the phone was unlocked, but running the OTA 2.3.5 I believe]. Everything seemed to be working fine the first week or two, but now there appears to be a serious battery drain or leak after I power the phone down. I can charge the phone to 100%, power it on and use it for a period of time, then power it down with 90% or more battery life, but when I turn the phone back on, the battery will either be really low, or completely dead, where the phone won't respond at all until I plug the charger back in.
I reflashed the phone with an AOKP ROM to see if that'd make a difference, but it didn't. I tried using the first battery and the drain/leak still persists. The commonality between the two roms is the Devil kernel, so I'm going to flash a different ROM with a different kernel to see if that makes a difference. I also installed the app mentioned above to log the battery stats/usage to see if anything stands out there.
Has anyone experienced something similiar - the Fascinate consuming battery life while powered off?
Yeah the power off leak does seem to exist.
Can't remember the cause though.
I've not tried to really confirm,, but try popping the battery out then back in after you have powered off,,, then check after it has sat overnight to see if drain still exist..
Mine i just always leave on a charger overnight.
.
[Q]
Thanks for the reply. I'll try that. I've left the phone on today, just put it to sleep during periods of inactivity, and the battery is currently at 75% with occasional mild use after 8+ hours "on".
[edit 11-29-13]
After almost two weeks of use, I can confirm that if I power the phone down and do nothing else, the battery will continue to drain to 0%. If I power the phone down then remove and replace the battery, it's fine. It's an extra step, but it works. Thanks again.

[Q] Best radio+rom+kernel for increasing battery life?

Hi everyone, this is my first ever post on the forums so don't be too harsh on me lol anyways, my question is what is the best ROM + radio + kernel combination to get the longest battery life out of my stock thunderbolt battery? Currently I am running DasBAMF 2.0-5 the MR2.5 radio and the dream kernel. I haven't really noticed a huge improvement in my battery life since I flashed this rom a few days ago. I have seen people who claim to be getting 10-15 hrs on one charge. I don't think I need that much because I charge overnight every night, but it would be nice to know how people do that. also, what are your thoughts on juice defender? thanks!​​
I am currently using CM7 R1.2 w/ the MR2 radio and I get very good battery life. 10 hrs plus with minimal use on the regular battery.
I've been running Gingeritis 1.0 with JuiceDefender Ultimate and I've been getting anywhere from 16-20 hours on the standard battery with regular use (facebook, email, words with friends, browsing, etc.). What I find most helpful with this rom is the brightness slider in the dropdown quick settings. Unless you're outside on a bright day or it's absolutely necessary, keep the brightness as low as you can comfortably use. I've found this to be huggee in the ongoing battle to get better battery life.
And if you can tolerate life without 4G, use an LTE toggle app to keep your phone on 3G. This also helps a lot.
i like the Inj3ctTh3ory rom so far.
It looks to me that all MR2 radios use more battery. The best battery performance for me was on BAMF 1.7 and MR1 radio. I would use 2 to 3% battery on standby overnight, with the phone on 3G. I am on BAMF 1.8.6 now with the OTA radio and the overnight battery usage is up to 10%. I will keep testing, but I think stripped MR1 ROMs have the best battery performance.
Sent from my ADR6400L using XDA App
BAMF 3.0 RC4, imo 3.4.0, OTA MR2 Radio... constant 40-45 hours on the extended battery.
How I maximized my battery
In terms of my battery I just wanted decent battery life without using a tone of extra apps to do it. I'm using the CM7 RC 1.2 with the MR2 Radio getting about 20+ hours of battery with standard use. I am not using Juice defender or any battery saver apps. I am just using Tasker to turn on and off my Wi-Fi when I'm not at home, because I hate doing manually
One thing I did do to maximize my battery life is after I flashed my new ROM I did the following after searching multiple forums for battery optimization methods
1. Charged my Battery to 100%
2. Did a Bump Charge Cycle 4 times, and then turned on phone
3. This step is probably key. Downloaded the Battery Calibration App. You can find the app in the Android Market.
4. Plugged in the charger until the Battery Calibration App read 100% and 4200+ mV. I found that even after bump charging my BW battery widget would say 100% and the led would be green. However when I go into the Battery Calibration App it would say 99% and the mV would be about 4160. I just plugged it in and waited about 30 - 45 minutes and it would finally be fully charged at 100% ~4200 mV.
5. Press the Battery Calibration button in the App to clear the batterstats.bin and unplug the phone. Do not shutdown or reboot.
6. Let battery drain completely without plugging it in (USB and AC)
7. After it completely dies Charged battery straight until 100% with no interruptions.
I'm getting good battery life without having to use juice defender or anything, and that's also with streaming bluetooth music everyday driving to and from work for a total of 1 hour. I also keep the radio at 3G the entire day unless I really need high speed data. And unless I'm in the car, Bluetooth is turned off. I'm pretty sure these steps should work on any rooted phone regardless of ROM.
I tried many different rom and kernel across the forum... I dun see any differences in term of battery life, just go with the one you love.........weeeeeeeeeeeeeeeee
My bolt gets better life running Ziggy's kernels for some reason. Not sure why, but it does. I've tried every sense ROM out there. +1 on the post above. Go with what works best for you and the way you use your phone.
courtesy of my rooted bolt
I've found cm7 (cm7 kernel) to have the best battery life for me, getting up to 28 hours with light use and no 4g. I find the auto-brightness on cm7 to work much better than on any other ROM I've tried, and for some reason all other ROMs drained the battery around 50x faster while idling. I can leave my phone unplugged overnight and expect to lose maybe 2-3%.
There certainly is no universal solution though. That is the only certainty
Whatever rom/s you test with...make sure you try various kernel versions (lean kernels mostly) to find what works the best.
I've tried them all,
GINGERTH3ORY V5.0 DreamKernel is my favorite one. it's super fast and very responsive.
Battery life is best on this one .
I use speedtweak batt saver ondemandx.
I'm on Bamf 1.8.6 remix right now with the OTA MR2 radio and getting about 14 hours on 3g all day and 8.5 hours if on 4g all day. Still looking for something better.
I have had a lot of luck with Inj3ctTh3ory. I have only had it now for two days but I'm already impressed with how long the battery has lasted. I have not experimented with any Kernel/CPU combo's yet but it's performing so well now I might not mess with it.
ROM and kernel linked in my sig. I'm using the 1.4GHz extreme UV with interactivex speedtweak, I love it. Bulletproof stability and with mild/moderate use I can make it through a 9hr work day with 50% left on the stock battery. 4G left on, everything syncs every hour. I don't get 4G coverage at work, I don't know if that helps or hurts, but I do leave it on.

[Q] Battery Problems!! What Can I Do

Hi. I know there are tonnes of battery related threads out there but I would appreciate if I got some personalized help.
I am running Trigger 3.2 Final with Bali v1.8.4 and the JK6 modem.
I have gone through all the modems available for Froyo and JK6 gives the best battery life for cell and data. No overclocking or anything.
The problem is I get extremely bad battery life on data on all modems. JK6 seems to be the best of the bad. With data off, I can get 20+hrs with light phone usage, but the moment data is turned on, the bat percentage just drops like a rock. If I enable data and browse the net with Opera Mini (no flash), a 100% charged battery can be reduced to to around 30% in around 1 hour. Sometimes more, sometimes less.
If it is the battery needed replacing, why do I get excellent cell life with no data activated. Bali is supposed to be battery efficient, but I am bleeding power. I bought those cheap knock off batteries from ebay and get the same results.
Brightness is on lowest, syncs are all off and email checks every hour I think. Nothing else I can think off can be chewing the battery.
I have calibrated the battery many times and makes no difference. I should also mention that I had worse battery life on the bionix roms.
On battery use,
Display takes up around 83%,
Cell Standby 11%,
Idle 5%
What can I do? Is there an app that will tell me if I should replace my battery or anything. I am all out of options right now
Bali Is The Problem
I just read about this same problem from other users, the Bali kernel eats up a charge cycle extremely fast and has even caused major over heating problems!
My suggestion is to go to a different kernel or change the ROM completely to something less power hungry
it could possibly be the batttery itself, mine did this a while back and replacing it helped, maybe even upgrade to the extended battery if a little more bulk doesn't bother you it's a great option try a different kernel, i use Bali and am not overclocked with the JK6 modem and text all the time at school I then got an iPod touch and stopped using my phone for music and it saves me an average of 30% battery 0_o idk why but oh well

Standby Battery Life

Hi all
I know battery life has been discussed quite a bit, but Ive found most, if not all, discussions are "runtime" battery life, not standby..
For me Standby is important as I dont use the TP that much, but when I do I dont want to see the battery a 25% or lower!..
Currently webos 3.0.4 seams to drain around 5-7%/day, whereas Android CM7Alpha3.5, and Xron b2.1 appear to be about 20%!!
I know this is still alpha, but this , and only this, issue is stopping me from switching completely to android...
Any comments??
ps Dont get me wrong I know this is alpha, and the CM & Xron guys have done WONDERFUL things, just thought Id ask..
Anyone tried the new Miui build?? is it based on CM7?
Will CM9 be better considering its Android 4.0 "built for tablets?"
thanks all!
i mean, basic phone stuff still applies here. turn off wifi, etc. certain apps will kill your battery more than others (ie scrabble), even when idle.
idk, i find that it's easier to just shut it down completely if you know you're not going to use it for 8hrs or longer. i leave my tablet on all day when i leave for work and come home to see it about 10% lower, but i don't pay much attention to it.
I been at work all day long 10:30am - 9:00pm... I didnt have time to use my TP at all during any of my breaks so it was in standby the entire time.
When i finally got home and turned on my TP it was at 92% out of the 99% it was at in the AM.
Running Xron 2.2, i cut it down to 130mb, not a single problem yet since I installed it.
Hi guys,
good comments!
@thekillingtree : Yeah powering down is one option, but the beauty of a tablet, you keep it on standby...
@jzen : mm thats not bad, however 11hrs=7%, therefore thats about 15% over 24hrs...
Yes I know "things will" drain the battery when in standby when running in the background, i suppose Im comparing it to things like an ipad (less than 1%/day drain in standby), webos which is ~5%/day in standby and even the NookColor (v1) can go for 2-3 weeks in standby..
anyway, its still alpha for me Im hoping standby time will improve when it goes beta etc..
for now I'll simply keep it "topped" up!
Angelo
i'm genuinely curious how long the standby life will be. i fully charged my tp this afternoon and i'll see later how low it is.
i never really cared since i charge it every day or two.
Firstly you have to remember that the battery status monitor in android is all over the place and can never be accurately relied upon.
Flatten the battery (yes, I know it's bad practice!), then fully charge, wipe battery stats and leave alone until battery is flat again.
Then you get definative battery life, for your device/battery combo.
I know that when im done using the touchpad for a while.... i turn off my wifi.
the battery barely drops when wifi is turned off.
Idea: i wonder if installing juice defender will solve this issue.
--> Juice defender turns off radios and preserves battery life on my android
phone it might do the same on the touchpad. Just a thought i havent
tried it yet
good idea!
Actually yeah, juice defender worked a treat on my htc legend.. might help with the cm7 rom too
Sounds to me like it is not going into a deep sleep. I charged my tp fully last night, went to bed and woke up with 65%. I know this was an issue for cm7 and miui on my Droid x.

For this to be a meaningful comparison, you need to be running the same apps on webOS as you are on Android, and understand how the apps work on each OS (e.g., background processes, network usage, etc.).
The Touchpad has a 6000 mAh battery. According to Battery Monitor Widget (in Android), my TP discharges at about 40 mA while idling with the screen turned off. This is with wifi enabled and whatever background processes are running for the 150 or so user apps that are installed. If I were to just leave the tablet alone, it will drain the battery of 40 mAh in one hour. In 24 hours, it will have drained 960 mAh. 960 mAh out of 6000 mAh is 16%, so that's seems about right.
It's been a while since I booted up webOS, but I recall that the Govnah app will record battery drain as well, so you can see if the current is lower or higher with webOS.

ICS ROMs and the battery charging issue, possible cause?

In the CleanROM ICS thread, Marine6680 posed an observation that I think bears looking into.
Please vote only if you are using an ICS ROM.
EDIT TO ADD***
Also please vote based on how your phone behaves while it is turned on. If you experience different behavior when the phone is off, please post that as a response.
END EDIT***
Marine6680 said:
I have both the stock and the extended battery. My stock battery has stopped charging fully, only to 92%, my extended charges normally. My fiance's battery will not charge fully either. It is stock as well.
So it could be that these new 3.8v batteries (which are tweaked chemistry versions that have a slightly higher voltage than standard 3.7v) are not supported by the new kernel's charging controls. (which seems odd that it wouldn't) That is, if that is even controlled by the kernel and not hard wired into the mainboard.
So it may be an issue with the batteries... or not. If it only happens with the stock batteries then it will be harder to say for sure.

I've posed the question in both the CleanROM and Ineffabilis ICS threads, but figured I'd post here to try to get all ICS ROM users to see it.
So far, all responses in those 2 threads have been that people with charging issues all had 3.8v batteries and that people with no charging issues (myself included) had 3.7v batteries.
Please respond here with your findings. Just pull out your battery and look on the back, top line of text.
I'm not sure what can be done about it, but at least it would answer a question that seems to be annoying a lot of people across ALL ICS ROMs.
Great idea for the poll, but still wrong section. Should be posted in General.

Sorry. Can a mod please move?
I have the 3.7 battery and have had no issues with charging at all.
I have a 3.8 for about another 3 hours. I'm stopping by Verizon and getting a 3.7. I dare them to try to tell me no.
I have a 3.7 with no charging issues.
Well, my battery lasts like 2 hours since I put ICS on there but I can't tell if thats the usual terrible Rezound battery life or something wrong with my rom.

If I charge too 100% while it's turned off (since I have the 3.8v battery), I get great battery life on ICS. Yesterday I got around 16 hours with 4g on all day under normal use. On stock GB and the two GB roms I tested out, I was getting between 14 and 15 hours on average with 4g turned off.
If I try to charge with it turned on and experience the 87% ceiling, I get horrible battery life. 10 hours max, and the battery seems to discharge very quickly when I'm actually using it.
on my De-Sensed ICS Rom it doesn't charge up to 100% pretty much stops at around 98%~.. I have pretty amazing Battery life Could go an entire day with out hitting 20%, but then again I don;t have alot of apps
I have a 3.8v battery, running ICS, no charging problems, no battery life issues.... no nothing.
The ONLY strange issue I have, and I've had it since day one on GB, is that when i unplug my phone from the charger it will say either 99 or 100% on my battery widget, however if you wait a bit and then look at the battery stats chart later in the day, it shows that it began discharging from 93-94% rather than 99-100%. I simply assumed the battery scaling in software was slightly off from what the battery itself is reporting, but since it doesn't seem to be a problem at all I have just ignored it. The battery easily lasts all day with plenty of juice to spare for me.

The battery easily lasts all day with plenty of juice to spare for me.

That's normal if you're not bump-charging.

If I charge too 100% while it's turned off (since I have the 3.8v battery), I get great battery life on ICS. Yesterday I got around 16 hours with 4g on all day under normal use. On stock GB and the two GB roms I tested out, I was getting between 14 and 15 hours on average with 4g turned off.
If I try to charge with it turned on and experience the 87% ceiling, I get horrible battery life. 10 hours max, and the battery seems to discharge very quickly when I'm actually using it.

wow, 10 hours is bad battery life on a lte phone?
If you aren't in a LTE area, make sure to set the phone to CDMA only instead of CDMA/LTE since it will forever search for an LTE signal... Thought I'll share that little tib bit.
Oh and In my situation I'm always connected to Wifi, Home,School, Work so I go into *#*#4636#*#* and under Phone Info I switch to CDMA only (1x) instead of CDMA Auto (3G) since in my commute I'm not stream/downloading anything... So keeping the Phone at 2G all the time makes for an even better battery life
But To each their own
** Since the issue is more ICS centered, I (among others) would blame this on the Leaked (unstable) battery/power drivers... So only until the official release we can't blame ICS as a whole (for now)

Got 1 day 4 hours with 40 percent left on your rom everything left as is. My issues with the music player was the only reason I went back to GB. That issue was across all ICS roms.

Maybe "horrible" was an overstatement, but it's certainly worse than what I was getting on GB or when I'm actually able to charge fully. That's also with 4g disabled, which I should have mentioned.
I have 2 different rezound batteries and both are 3.7v and had zero charging issues with any of the ICS roms I've been running.

So... do you want a 3.7v or a 3.8? Whats the difference?

Which rom are you on?
Posted this in another thread but:
Just got off the phone with Verizon, they said they are pushing an OTA that addresses battery issues. Take that with a grain of salt
He texted me the info: 2.01.605.00: Baseband:0.95.00.1118r
