Battery question. Yet again - Vibrant Q&A, Help & Troubleshooting

So I know this has been talked about over and over again....even so..can someone please explain to me why this phone running stock rom ..custom rom...stock kernel custom kernel ...whatever the combo...drains solo fast? I am on my 2nd battery tmo nicely sent out free of charge thinking i got a bad one...yet the issue remains..i charge overnight..unplug ..go to work...8am ...stay in the shop 2 hrs...phone dark/silent.. get loaded up (delivery driver) get in the truck. Stick my phone on my clingo car mount turn on my screen to start an mp3...batery is at 85...from there i take maybe 60 mins of talk throughout the day..have mp3player running and use a Max of half hour navigation...around 2 pm battery is down to maybe 30 if not less...by the time i leave work at 4 it is in the red telling me to plug in.. mind you i even use a car charger here and there throughout the day...i have noticed this thing drains 3 times faster than it charges..i can even have GPS on...charger in...and it will stay about even or more times than not be less then when i plugged it in ...
Again having read a million of these posts...I cannot find any rhyme or reason for this other than luck of the draw? Some get 40 hrs some get 5?

Woah your post is really hard to read.
First of, using the GPS navigation app is very cpu intensive. You could tell it is when your phone starts to heat up. The more CPU intensive an app is, the faster the battery will drain. Secondly, if you have alot of syncing aps, your battery will obviously drain faster. My phone will last upto two and a half days without syncing and with heavy use. I'm not sure what you are trying to say with the charger, but the car charger isn't as powerful as the home charger from my experience--but I have noticed some car charger are *more* powerful than the other lower quality car chargers. Like with some chargers, my phone was able to charge while playing music in the car.
There is an issue with the DRM integrated with the newer roms (like the OTA). Together with the samsungs mediahub, it drains a signifant amount of battery. Some users report having better battery life after uninstalling or freezing the said apps--this requires root priviledges of course.

battery draining while using GPS.

I just went on a trip and about 2 or so hours into the trip my cell phone went dead even though it was plugged in. I was using my GPS. I recharged my phone and tried again and I could see the battery was draining even though it was plugged in.
Is there a fix for this problem? I'm was using Sprint ROM, but switched to Might Mikes, but still have the same problem.
what ends up happening with the pda devices is that it looks to the battery for energy only. even if it's plugged in if you drain the battery faster than it can charge then it will go dead. i don't know if there is even a different rom that can cercumvent that, but that would be the only way to fix it.
...or if you could find a gps program that uses less energy. that should work too.
I tried again using the GPS, but this time I had a DC to AC converter and plugged in my phone. Although I didn't run the GPS that long, maybe a half hour or so, the phone battery didn't loose any noticeable charge. It was fully charged when I stopped the GPS.
I'm also looking to replace my battery with a higher capacity battery. Can anyone make a recommendation? I don't want a larger battery as far as size, but one that has more capacity. Let me know if there is a battery on the market that will meet my requirements.
Touch Pro has a safety feature to stop charging when the temperature sensor goes past a certain point. It is much more likely to reach that point when you are running GPS and in car with the sun beating down.
Workaround for that is to turn on the AC.
I had the same issue this May when driving through GA while on vacation.
The phone does stop the charging process when it feels it is too hot but will continue to operate thus discharging the battery quickly but never letting you get a charge in.
My solution was to buy a mount for the phone that clipped onto the AC vent and let cool air run on it the entire time and that solved the problem.
Hope that helps.
Yes, anytime I run the GPS the phone does get warm. However, I do have a vent mount holder for the phone with AC blowing right on the back of it. That doesn't resolve my problem.
I'm interested in a very high capacity battery if anyone can personally recommend one.
Have only had my sprint pro for 2 weeks and concur the battery life is bad. I find heating problems during lots of tasks and sometimes doing seemingly nothing(in sleep mode). I found that my gps was draining the battery even when not in use. I installed a cab to toggle it and that has helped alot. My data is set to go off automatically after a short time also. I'm trying every tweak I can think of and googling for more.
The oem batt was 1340mAh, My old gsm pro had an extended 1500mAh which I tried , with little improvement. I'm currently running a 2000mAh extended with the enlarged door and this helps but lots of juice is still draining away. On a positive note, the warmness seems to be mostly gone. My goal is to be able to go a full day with moderate usage. Today may be the day. I think I saw a 3000mAh as well, maybe at seidio. I was going to return the pro and get another one, but it sounds like they are all the same issue. An awesome phone, a real shame this is a problem. I think data off and gps off will help me alot. My $.02
Can you share the GPS toggle off and on program?

I installed the program and I see the GPStoggle.dll under windows, but I don't see anyway to run the program? How do I enable and disable it?

Battery problems

This is my 4th note. The 3 I had previously the battery lasted a long time. I kept the same battery from the first one in all three exchanges. I took the new battery for this fourth one. Could this battery be a bad one or should I return the phone again for a 5th time. I don't wanna take a chance getting a phone with the problems I had on the other 3.
Just looking for some opinions

Good Lord, 3 exchanges! Wow... try running the battery all the way dead where the phone shuts itself down, keep it on the charger and charge it overnight (or in the realm of 8 hours) while leaving it off and see if that makes a difference. I ran my batt that way once and I'm getting 18 or so hours per charge (depending on how much I play with it).

Reflash your modem, rom, and kernel. See if that helps
I only get about 3 hours of screen time myself. Seems normal for this phone. The huge screen eat up battery fast. Plus if your using LTE, so good bye to your battery.
I don't think you have a bad phone, That's just how it is in my opinion...
so whats your total at the end.. like say.. 5%..?
If you're getting about 3hrs screen time, I'd say you'd be on par with what I'm getting. Some days I can eek out close to 5 hours screen time, usually on the weekends when im at home and on WiFi.

Auto Brightness?
I don't know why you guys are getting such horrible times. With regular use I'm getting an average of 8-10 hrs screen time, depending on what I'm doing. I'm running Saurom RCVI, with Da_g OC Kernel, and tweaked a few of the JKay settings. I recommend charging to 100%, wiping batter stats, and doing a power cycle on it. That's what I did after installing above Rom/Kernel, and battery went from from 4-5hrs to at a minimum 7hrs.

I would like to see a screen shot of that
Fighting battery problems here as well. I'd assume it was normal for this phone, except when I see people posting great times.
1 week old phone. Switched to Saurom yesterday to see if it's any better. Screen regularly at 5%. Usually on Wifi most of the day (and I'm not in an LTE market yet). I set all my synchs (rss, weather) to 4 hours. Others (Twitter) are manual. Only Exchange Email is push.
Using Cpusy & BetterBatteryStats to try to see what's going on. Could be a bad battery - could be that the number I'm seeing is wrong.
Anyway, I'm getting about a 7% drain an hour *with the phone off* ! I'm even rebooting as needed to make sure it's in deep sleep & not 384 (which is very, very annoying). Unplugging the phone @ 7am means a dead battery by 3pm. And if I'm using the phone, it's more like 12-15% an hour (min screen, reading a book). Been charging in the car and at work - whenever I can for now.
Going to try to run some tests on the new rom. Leave phone off for 30-60 minutes & track % loss. Then, maybe put it in airplane mode & try again.
Some weird ones I see to often - Adfree, Maps, Alarm Manager (which I understand can come from almost any of my apps). Oh - tried Juice Defender, no help there either (didn't make any difference at all)
Finally, in the car with Waze (gps), a Podcast Playing, and the screen cranked up for visibility - the car dock/charger keeps the phone about even. On my HD2, a drive to work would charge up like 20-30% of my phone.
Really, really hope I don't need to carry a 2nd battery for days when I can't keep the phone charging.

How often do you get exchange emails? I stopped using push exchange email as it was a huge drain on the battery with the volume of emails I get...
With this phone the screen draws some serious juice, so if your using you phone in the car with the screen on its using about 950mah of juice, so your car charger will likely only keep this phone from losing power, it may not gain any juice, and it may even loose juice depending on charger power and what the phone is doing currently.
This is also why most of us are seeing about 3 hours of screen on time, as while the screen is on its using probably 700-800mah of power. divide that by the 2500mah battery and you can see why...
You can try other programs to try and help with things like background data, undervolting, etc, but that's all going to have a small effect as the "problem" is the screen, its eats up most of your juice. If you want to save battery you need to go after the big thing, the screen, not the little things. However short of reducing the brightness there's not a ton you can do about the screen. It is a big screen, and it needs big power to drive it.

I get about 5 an hour during the day. Will try setting it to once an hour in my testing instead of push.

I *think* (need to double check) that the charger is putting out 1A. Where did you get the 950m number from? Is there an appx. chart for different levels of screen brightness (how about 50% for example when in the car? oh - and how much lower is the 5% I use indoors?)
Agree, the #1 thing is the screen itself, which is why I get very confused when I have the large drain with the screen off.
I'll also have to try a test today where I turn on my podcast, but leave Waze off - and turn the screen off while it's charging in the car.

950mah is an educated guess. If you have root you can run this in a terminal to see how much power you car charger is giving the phone... (su first)
cat /sys/class/power_supply/battery/batt_current_adc
I usually get about 9100 for a result, which is 910.0 mah. and my phone will charge barely if I dont have gps going (screen on). if screen is on and gps is on the phone will slowly discharge, so that puts the phone power usage at about 900mah with screen on, so maybe 950 was too high of a guess. So when the phone screen is on, your using a ton of juice for such a small battery.
If I use just a podcast app and the screen is off the phone will charge much faster while in the car. If I have google maps running, it stays almost even...
You could even calculate your usage. She how many minutes your were driving with the screen off and the phone charging and note the amount of battery% gained in those minutes. You'd see a huge difference in charging times with the screen off. In my 50 minute commute to work, I gain about 20% battery charging with the screen off... With the screen on, I see almost nothing.
Seems like some days are better than others.

Batterylife comparison: Stock VS CM9 VS CM10

Hi all
This is my first post, so let's hope I've gotten it right and am abiding by all the rules and the n00b video. And yes I did search for a good 10 minutes about batterylife and battery before posting and didn't find anything relevant.
I've recently swapped over from Apple iPhone and I'm now very much enjoying being on Android. However batterylife is a big concern for me, as on iPhone I could go 2-3 days without charging and now I can barely make it home from work and I definately have to plug it in before dinner. And yes this is with me closing down applications, wifi when not used, bluetooth when not used, running latest kies released PHONE:LFB firmware and so on.
So my question is... how is your batterylife after having rooted and installed a custom rom? The one I'm thinking mostly about using is definately the new Preview 3 (or perhaps wait for 4 or 5) of CM10, that XpLoDWilD is working on. Does anyone have any experience with the batterylife before and after?
Thanks a lot for any help you can provide! :highfive:

That's very weird. Are you international or a US S3? I easily get 3 days battery, very easily. Perhaps try turning off useless stuff like bluetooth, gps, wifi, etc when you're not using them. Turn off push email and other useless crap. See how it goes then?
I still have the stock ROM, usually 3.5 days battery before it gets to 10% and i charge. I'm going to go to OMEGA rom soon though.
I have tried almost all custom roms out there. And I can easily say the battery life is not any better if not worse on custom roms.
Stick with the stock rom. I would however recommend flashing a custom kernel like speedmod or phenomenal. They definitely give you that extra juice you need at the end of the day. The idle time and screen time has increased for me 10 to 20 % compared to stock.

I'm using the international version. I did turn off bluetooth and wifi, but not gps. Will try that aswell. I have manuel mail check every 1 hour, but will try to set it to 4 hours.
However from what I read in the reviews on GSMarena and other sites, it's quite normal to only get 1 day worth of battery.
Description of a pretty basic day with the Galaxy S3:
I usually unplug mine at 6 am, with wifi and bluetooth off and screen always on auto brigthness. Then at 7 am i turn on bluetooth for my earphones and bike to the train station and browse the web and such for about 45 minutes in the train. When I arrive at work it's usually around 80% battery and I turn off bluetooth. Then I'm at work from 8 am to 4 pm and check mails, texts, calendar and possibly make 1 or 2 short phone calls. At 4 pm I think the battery is often around 40-50%. Then again on the ride home I use the same, so it's usually around 20-30% when I come home. I then usually turn on wifi and play a couple of games, or watch some Netflix on it while I'm doing some other stuff or attach it to my stereo and play so music from Spotify on it. At 6-7 pm it's usually beeping at the 5, 10 or 15% marker for more power and wants me to plug it in to a power source. If I try to wait till I go to bed, I usually end up having it automatically shut down from lack of power.
I'm wondering if this seems normal or if perhaps my battery is faulty. From the review at GSMarena it seems quite normal and that's just the way Android is. They even gave it a good battery rating inspite of saying that it would only last them a day.

Okay, thank you for your reply
it all depends on the usage i have an iphone 4 as well and i have to charge it by the end of the day (at 10pm). So it dpends on what you do with your phone if you use 3g all the time thats not gonna last long if you have syncing on all the time and gps that wont help...if you just let it idle then you can get 3 days uptime with maybe 1 hour screen time.

My basic day is charge the phone at around 8pm, unplug at 10pm. I never charge overnight it's pointless (not that i think it'll hurt it). Wake up battery is usually around 95% after my alarm goes off. Brightness is about 60%. I don't browse the web very much, and I don't play many games, let's say 1 hour of web and 1 hour of games/videos/music per day. Maybe 1 hour of maps too. Mostly though, I text message and phone call.
I don't think yours is faulty, i think it's quite normal, it seems like you're a heavy user, I'm a light user. If I used my phone as heavily as you did i'd be happy with 1 day of battery.
One day of charge (the battery being at 20-40% at the end of the day depending on the usage) is quite normal.
I've found CM9 with Siyah to give the best standby battery (1-2% drain per hour with 3G and Sync enabled) since it's very lightweight and has no battery-draining bloatware other than what you install.
CM10 is still too new and unfinished to be battery-friendly, it's not that bad though.
However sometimes it will chew the battery for no freaking reason (at least I cannot found any) and the CM9/CM10 stock kernel is not that battery-friendly on active usage. No Siyah yet =(

No way is that good man, that means that if you leave it on standby alone you lose 25% per day. 0.5% per hour would be good/normal IMO.

My DIY p769 extended battery.

Hi fellow l9'ers
I purchased an OEM battery to have as a spare battery since I'm usually out of battery when I most need it but forget to bring it or charge it. After having so-so experiences with aftermarket extended batteries on other phones I decided that if I wanted good results on the cheap I need to make it myself. Still testing it out but initial impressions are good.
BTW.. yes it looks horrendous and I do know that it could blow up, ruin my phone, cause cancer and start WW3.... but thanks for your concern.
Source of inspiration. http://forum.xda-developers.com/showthread.php?t=1800177&highlight=battery+mod
9/4/13 Update.... after using it on a daily basis and swiping back and forth between the oem battery and my jerry-rigged battery I can say its definitely working. The performance has gotten constant and I did a battery drain comparison between the 2 using the app called FAST DISCHARGE. All option selected and cpu set to full load with temp set to unlimited. I did remove two of the jumpers and only left positive and negative connected.
OEM BATTERY........... 2hr 5min 13 sec
JERRY-RIGGED BATT..........3hr 35min 21sec
I suspect that it doesn't last double since both circuits are being powered when charged...... the first battery to be fully charged send a signal to the charger to shut off hence the lack of full power.
Over all for $10 bucks I'm not complaining.
How does the battery stay in place? double side tape?
Also, what is the battery life on this uhmmmm... phone?
How is it?
I am very interested in trying this if your results are good...How has your battery life been affected? Has it doubled? Do you use a case that works with the new "power bulge"?
I did that to my old i897 captivate. you only need the positive and negative connected. you're connecting the two circuit boards together which may cause problems. i would remove that one. Unless you can find a battery charger that supplies more amperage you most likely will never get that battery fully charged no matter what the android meter says.
Ok, after a few days of heavy usage I have come across sporadic performance results. In a few occasions it would out last the original battery under the same usage and other times it would perform as a stock battery. I plan on purchasing an external charger since I suspect that both batteries are not fully being charged as the previous post mentions. I will also disassemble the second battery and take the circuit out of the equation. So far I am pleased with it's performance even though it's not consistent.

Cool. i work in batteries so i didnt check out dudes guide other than his soldering was good lol. essentially all you're doing is connecting the batteries in parallel. since both batteries have a circuit board that controls low voltage and temperature safety, you only need to use one as the battery will still be a 3.6v cell just double the capacity. stock LG charger shipped w/ L9 outputs .85 amps so if you could find one that did 1.5amps or 1500mah you'd be in good shape.
Like @Meda808 said,you only need to connect two pins... + and -.You will also need stronger charger but... There is a circuit in a phone which controls power to battery(I think that that's why is one of the two middle contacts on battery) so... Maybe with external charger?

Small update......
So far so good, no major issues. I purchased the anker standalone charger and it charges the battery but it takes way to long(10-15hrs) So I just charge it in the phone now. The battery lasts me a full day under heavy heavy usage. Prior to this by 2-3pm it was out of juice.
I have noticed that it has become less sporadic the more I use it.
Iheartradio 4-6hrs a day, dish anywhere 2-3hrs a day, calls:30-1hr. This is with WiF(thanks Home Depot), data and Bluetooth(LG Tone)on for most of the day.../.. I'm happy I did it.
I unplug at 4:45am and plug it in by 8-9pm with about 20-30% left.
I have not modified the connection yet so I suspect that it still might not be fully charged even with the aftermarket charger.
About the hump..... I got use to it quiker than I thought.
hahaha ill give ya props for ingenuity
9/4/13 Update.... after using it on a daily basis and swiping back and forth between the oem battery and my jerry-rigged battery I can say its definitely working. The performance has gotten constant and I did a battery drain comparison between the 2 using the app called FAST DISCHARGE. All option selected and cpu set to full load with temp set to unlimited. I did remove two of the jumpers and only left positive and negative connected.
OEM BATTERY........... 2hr 5min 13 sec
JERRY-RIGGED BATT..........3hr 35min 21sec
I suspect that it doesn't last double since both circuits are being powered when charged...... the first battery to be fully charged send a signal to the charger to shut off hence the lack of full power.
Over all for $10 bucks I'm not complaining.

Nougat Battery Life

Okay, I have seen a lot of people having issues with their battery life. This is a couple things that I have discovered and this has been checked with 2 other A7's.
First is wipe your Cache Partition. If you haven't done this. Please do as it helps drastically.
Second, some say it take 2-5 charging cycles to straighten out. As I charge my phone every night because I use mine phone a lot. 2-5 charging cycles is not it. I prefer 2-5 days of use and charging. This is for any device I have ever had. This also includes the tank of all phones, the Nokia 5160.
Third is Dolby. Yes it is nice. 4 Day test -20% battery over 7 hours of use average. This is why I don't use it unless I am in the car plugged into the car charger or wall charger. This is only true when using Dolby. Battery drain from stock music app with Dolby off to Poweramp (what I use) appear to be the same me.
Forth is SYNC. I don't know how many people use it but I saw between 10%-25% battery drop over 16 hours with it on. The reason for the swing is Cell Data vs WiFi. Wifi uses more because it updates more. The update frequency seems to be every 15 mins on WiFi vs ever hour on Cell Data. This battery drop was not seen by me in MM. I grabbed one of my other phones that is on Nougat and it has the same issue. So that is not a phone issues. That is a Nougat issues.
Fifth, now this one caught me a little weird. The power saver that everyone hates it seems like. Turn your power saver to Performance. Run it like that for 2-6 hours. If yours worked like mine. You will see no change in battery life during this time. Then switch it back to Smart power-save. And now watch your battery life increase. This one I cannot confirm on MM. But my battery increased by 25% by doing this.
Sixth and this one is important, Clear All Apps. Yes they load slower when you clear them out. But apps like Snapchat, Facebook, basically any social media, camera, are going to eat battery. This is known by many but often forgotten. I forget to clear all still. See if it helps you.
Seven, ZTE Locker, It is fun to play with but will drain fast the moment you get on WiFi. It will look for all the lockscreen wallpapers.
Now these are what I found out with the way that I use my A7. I know everyone uses their phone differently. What I call "All Day Battery Life" is 6 am to 10 pm. During this stretch of time I could be using my phone up to 13 hours of that. Very few phones can last on a single charge the way I use my phone. A7 is one that beats out the rest. My battery life went from 13% at 10pm to 39% at 10 pm. And it continues to get better everyday. Also this my be a joke but it worked for a Moto G4 and at OP3T. If you have a day where your battery just seems to fall fast. I mean like you are not going to get 6 hours out of it. Find a 5v 2 amp charger and plug in for like 10 mins. Battery fall goes away. It cannot be the factory quick charger either. I hope this little bit helps some of you guys out.
Thanks for this info!
Just an observation I've noticed since having this phone for almost 6 months.
When I use my older Samsung charger (slow charge), my battery seems to die off quicker. If I charge with the stock charger, the battery seems to last longer.
Right now I have not noticed it dying off faster. But I will keep an eye out for it. So far I have not had any fast drain battery days with mine A7 yet. I use the term "yet" because it is going to happen. I have not own a phone that has never had it. Just glad I can help.

I'm experiencing the same. Not sure if it's a fact or just feels like this.

I saw this drain you are talking on my Nokia, Blu, and Samsung 1 amp chargers. I have not seen it yet on my Asus or Samsung 2 amp chargers. It is really noticable on the Blu charger. I am going to put my chargers on a test rig this weekend and see if the amp draw to the phone is causing a voltage drop in the charger and cause them to not charge right.
We should not have these issues these days. My Sony Z3 has no issues doing 1.5 days without using battery saver. My Windows 640xl will go 2 days no problem. I don't understand why manufactures can't figure out battery life. I love the Axon7 but its the thirstiest phone I have ever owned.
Thanks for the suggestions, I'll give them a try.

I can't speak for Sony as the last one I owned was the Experia Play. I had the Lumia 640 XL though. I never got over 20 hours on a single charge. Battery Life is also tied to how a user uses the phone. My father gets 3 days on his OP3T. He also doesn't use it as much as I do. When I only use my Axon for calls and sms. I get 6 days on a charge. But for me that is not real world life. As a thirsty phone, I just don't see it with mine. The other two guys here that have one as well. They get 2 and 3 days on a charge. I know some people are having battery issues. Some are having charging issues with slow chargers. I saw it happen with a few of my slow chargers as well. I hope that my suggestions work out for you. I have been looking at other things to try to see if they help. That is the beauty of having two more Axon's in the area. Right now I have a non-battery annoying issue that I am trying to work through.
I am also updating the OP for another that I found. ZTE Locker.
