Sorry to start another thread on battery issues but I was unable to find a scenario like mine.
Hey everybody, Im new to the android scene, just got my vibrant less than a month ago. Before that I had an Iphone 3g. So far I like the phone but the battery life is horrible. When I surf the internet on wifi or 3g I noticed that I use like 3-5% in a matter of 5 mins. Is this normal? I consider myself to be a light-moderate user and have been getting and average of 12 hours or so on my vibrant. Also if it makes any difference when my phone is idle or being used my temperature runs around the high 80's low 90's but when being charged it drops to the low 80's or high 70's. What is going on? How can I get more 20 hours on my phone? With the iphone I used to get an easy 15 hours and still have like 40-50% remaining.

When I first got the vibrant, it had pretty bad battery life, I would lose like 25% while sleeping 8-10 hrs. So light usage would be like a day. Slowly I started to get longer battery life (2 days on light usage). Recently I could get up to like 3.5 days on real light usage. After updating to JI6, max I can get now is like 3 days. I didn't really do much and I tripled my battery life by just giving it time.
Thanks burntrat I guess ill be patient. And I must mention that I am running stock.i was just worried because my battery temperature gets colder when charging and warmer when idle or running.

Hey burntrat or anybody, has your battery ever acted sort of schizophrenic on you? I mean one day I leave it on standby and its drains like 1% in 7-10 hours another day I leave it on standby and it drains 18% in about 4 hours. Whats going on?

It happens
If ur super concerned get these 2 apps

My battery has been draining inconsistently lately. It drains faster in the 50-100% level. Under 50%, it feels like it drains slower while doing the same stuff.

Juice defender doesnt work for me, but ill have to try superpower, anyways I just feel that its weird that without anything changing, my battery drains differently on different days. Burntrat I think thats normal for every phone, the last 50% always seem to drain slower.

if your phone is draining a lot during standby or sleeping. There may be a rogue app out there or an app that didnt shut down properly. (I guess that would mean a rogue app)

Check ur services, go to settings apps manage apps running applications.
Or instead of that I brought the advanced task killer back to check on things
@aamir123 and burntrat: maybe you guys need to calibrate your battery? Also the stock rom usually has a lot of bloatware running in the background. Flashing a custom rom oughta do the trick.

How do you recalibrate the battery?
Sent from my SGH-T959 using XDA App
Try this. Download the system panel app from the market. You can set it to monitor your system and it will chart what applications are running and how much they are using the cpu. If you find you have some unnecessary bloatware running in the background download titanium backup and freeze those apps.

There are a lot of different ways mentioned in different forums. Try this:
Let your battery drain all the way to the point when it turns off by itself.
Charge it while its off until its full.
Unplug it, turn the phone on, then plug it in again.
After it reaches 100, unplug the charger and turn your phone off.
Once off, plug it in and let the charging complete.
Once complete, unplug it and turn the phone on. When everything has loaded, turn the phone off (note: no charging involved in this step.)
After it turns off, charge it one last time until 100%. After this, go into recovery and clear battery info (or cache, I forget). There you go
Oh, and its better if you don't download too many apps that monitor battery usage, cpu etc. cuz they will contribute to the battery consumption.

It isn't a good idea to let your battery drain all the way to zero since it is lithium ion. I think skipping that part and just charging it when it's on to full, then off to full, then on to full, then off to full and then wiping battery stats would suffice. Also you need to have clockwork recovery to wipe battery stats.

When the phone turns off by itself, the battery still has some juice left in it to prevent it from losing the ability to charge, if that's what you meant by not a good idea cuz its lithium ion. If thats not what you meant, then please explain why.

Agreed. In my case, I barely lasted 12 hours on moderate use with any of the JI6 2.1 ROMS (Eugene's, Bionix, Fusion, etc). I think after I updated to 2.2, all of the ROMS have been giving me 18+ hours on moderate-heavy use no matter what modem or kernel I use.
So where is the "unique" problem?

Hi folks....m using galaxy note...it's not rooted...the battery doesn't last long enough as it is claimed... is it something wrong with my phone or is this what they mean by long battery life... i text alot and during texting and playing gamea my phone gets warmed up and the battery lasts less than 3hours if i continue texting...my kernel version is [email protected]#2.....please help....

It sound like you have a faulty battery if it only lasts three hours, I think you would have to be gaming to flatten a good battery in that time.
John.
Mine is the same. If I'm browsing the web, using instagram, Facebook and receiving email my battery will go from full to empt in easily 3 to 4 hours.
Backup, factory reset, reinstall apps from market (try to install only the ones you use a lot at first), restore the data you need. If you're still seeing the same things happening, install a battery logger / system logger. Use this guide to see if there's a rogue app that's causing the trouble: http://forum.xda-developers.com/showthread.php?t=937080
If it's still acting up and you cannot identify any unusual drain, I'd ask for a replacement.
After you get things sorted, you can use apps like Juice Defender from the Market to prolong your battery life even more.
-KJ
thanks guys for the sincere contribution.... i hope your advices help me...
my top battery consuming activities are:
temple run
google play
msging
go launcher
and nothing else
gaming and browsing certainly make the battery drain almost visibly..
things above and beyond the above to try include..
1. reduce screen brightness
2. reduce frequency of or disable background updates by apps
3. no vibrate notifications
4. work more, play less!..lol
the battery life of the Note is great, unless you use it .. a battery monitor will allow you to see the battery drain over time..this will help when you address item #2 above.. if you accept default refresh times, and have lots of social apps your battery can die in 6-7 hrs without even using the Note at all!..
I really love when people give the tip to not use your phone as a battery saving tip

some hints for better battery life
Got mine the other day. First charge battery was fine. Second charge went down 7% in about 5-10 mins. Then it restarted :/ Came back on, down to 88%. Turned the phone off as was frustrating me as it restarted 3 times yesterday. But when I turned it back on I was at 83%?
Hasn't last me the day, it's on charge now. When it pops up telling me to charge it tells me to shut all apps and that using while charging may effect it charging. Is this correct? I didn't think it would have anything to do with it?
3 to the 4 hours continuous use is normal... Only if your phone is standby and then depletes in that time You should be worried. I recommend researching wakelocks in that case.
There are many variables that can atribute to batterylife depletion. Eliminate those first and you will have your answer.
I had best results on stunner version 19. To bad it has the death kernel (leaked ics)

Usually that wakelock is there cause you are charging, or have USB plugged in

Had the note for 2 days. It came with LA4 FW and updated via Samsung Apps for the latest FW.
Battery drain, that was none on LA4 became very strong!
Installed Better Battery Stats and discovered that the CPU was always running.
Factory reset solved it...

Are you sure? S4's battery is 2600 mAh. It should take about 15 hours or more to make the battery become low with minutes of gaming.. I have S3 mini and its battery is 1500 mAh and it takes about 12 hours or more to make the battery become low.
I can get 5 hours on 60 percent but I gotta be using battery saver with data off when I lock the acreen

Gaming or watching movies will discharge your battery in a few hours. 4,5 or 6 hours max. Depending on what you're doing and other stuff like wifi and screen brightness.

Was the battery life always terrible or is it just now?
I'm having a similar problem so I'll use this thread instead of creating a new one. I hope you don't mind.
My battery is draining at a rate of 15% per hour even If I leave it on standby, ocasionally turning on the screen to get a message on Whatsapp of checking the time. It was 100% this morning, 1 and a half hours later, 74%.
After reading on the forums that the cause of the battery drain could be that the phone was constantly trying to get network signal (in cases where the signal is poor, like where I live), I decided to switch on airplane mode. To my surprise, in 3 minutes after this the phone was in 75%. 10 minutes later and I got a 76%. As I write (on PC) it is on 80%.
That's right. The phone started "recharging" without a cable (I know this is impossible, just describing what the display shows me) after I turned on airplane mode.
Any ideas about what might be going on and how can I solve this?
Thanks in advance!
P.S.: It's not the battery itself, as I've bought a brand-new, samsung original battery and the draining was still the same
EDIT: the battery started behaving like this only a few weeks ago. So I'd assume that the signal problem could be helping, but would not be the main reason on why my battery goes down so quickly.

You could try that and see if it is a rom problem.
Otherwise try to borrow a battery from somewhere just to be sure it isn't the battery.
Hey guys i got a s4 for free a few weeks ago and the battery was having issues so i brought a new battery from Samsung for $50. I guess the phone is $50 now huh, still that's a good price. Anyway i have an improvement in standby time over the old battery that seemed to drain no matter what, but i only get around 2hrs to 3hrs screen on time full brightness with a mix of auto. The phone tends to get warm when its below 40% power. Also using the phone drains it at a fast rate, but standby only 1% per 8mins or so witch is good. Im backing up with twrp and titanium backup, ive tried recalibration, and im about to do a factory reset on this (stock touchwiz)
Sent from my LG-D320n using Tapatalk
Battery calibration apps are a placebo.
Anyway, let me tell you a little story:
2 weeks ago I watched a 2 hour movie on my phone. Started from 100% ans towards the end of the movie I was left with about 50% battery.
Screen brightness was around 60%, WiFi was enabled and the mobile reception was 4G.
All things considered I would assume I can get 4 hours SOT, since it took 2 hours to get from 100 to 50.
This is on a custom rom and battery oriented kernel settings.
Also take into account that I was watching a movie, so the CPU was idling most of the time. Doing tasks and switching from one app to another drives the CPU up.
Your screen-on time seems acceptable to me. I have to mention that my battery is one and a half years old, but I always took good care of it (I never let it discharge too much and never left it charge too much, as both of those, over time, can reduce its storage capacity).
Im using Albe95 rom with a custom kernal and the battery is draining slightly less, ive reduced my brightness to 60% and its drained from 100% to 77% in standby and extremely light use in 6hrs (about 4hrs standby drained 6% and 2 hrs of on off use every now and then drained about 17%. I guess im used to my old LG L70 D320n witch could hold up at full brightness forever. Will Cyanogenmod 13 bring much improvement for me?

You won't miraculously get 5-6 hours SOT even if the battery is new.
Maybe with lowest brightness, WiFi and mobile data off you will.
Underclocking and undevolting might help a little, but I don't see anyway of getting more than 5 hours.

There's a guide in the general section, _Bon_Bon's tweaks.., Something along those lines is the title.
It has a guide on how to increase battery life.
The guide is based on alucard kernel, though.
Alucard kernel is available for any 5.0 and 5.1 roms. But there is no public build for android 6.
Only JDCTeam roms have alucard kernel for android 6. Those roms are Optimized CM13 and AOSP 6.0 rom.

Ok so slowly things have improved but today when it was at 9% (6:30pm charged this morning) it froze up and i pulled the battery. Then it jumped down to 2% at restart! This has happened before (cant remember if it was on stock rom or the note 5 rom im using on it now) from 40% freeze, pull battery, restart, 22%! Any idea why this happens. I talked to samsung about the battery performance and they just wanted me to send the phone too as "its not just the battery" just for more money instead of honering their 3 month ****ty warranty! Stick it samsung my next phone will be lg like the rest, even though i only just brought this damn phone

The freezes might be caused by CPU undervolting, if you did any.
But the battery percentage dropping suddenly is a sign of a bad battery. It might drop 2 or 3% during the boot up, but not 20%.

Samsung say the phone is the problem. Today i got to 40% and it jumped to 30% within 20 mins. Then i pulled the battery and started the phone up, repeating this multiple times to see the battery percentage. It jumped between 24% 15% and 19% up and down each time i pulled battery and restarted (no crashing just to see what happens). Is this enough to tell Samsung ITS NOT MY PHONE.

Apparently they refuse to accept the possibility that they might have sold you a faulty battery, so they blame the phone.
I don't see how the phone might drain the battery from a hardware perspective.
It's possible from a software perspective, but since you changed roms it is unlikely to be software related.
Did you install any apps to check if the phone enters deep sleep? Or if there is anything keeping the CPU at max frequency?

Did you install any apps to check if the phone enters deep sleep? Or if there is anything keeping the CPU at max frequency?

Wake lock doesnt find anything strange. Even twrp battery indicator in my custom recovery experiences the same effects

Ok ive done it a few more times and it seems to possibly be a calibration issue. But ive calibrated it multiple times before

How did you calibrate it?
Battery calibration apps are a placebo. What they do is they delete the batterystats.bin file which, as stated by a Google engineer, has no relation to battery life or the battery display.
Also, that file gets deleted automatically at every reboot by android itself.
What you could do is:
First let your battery fully discharge, until the phone turns off. Then try to turn it back on. If it turns on, proceed to use it until it turns off again. Do this until the phone won't turn on again.
Now the battery is completely empty and you can plug it in to charge. Let it charge to 100% without interruptions.
Take into account that it can take up to 3 hours to fully charge.

Haha done this before to no avail. Will do again but i noticed battery life is generally better if i leave it charging for 10hours after its charged fully. Instead of taking it off when it gets to 100% but i think a long worded and very angry email is about to be sent to the Samsung repair centre

on my travels around google I've read many times that with lithium batteries you NEVER want to completely discharge or overcharge them. give it 10 minutes extra once fully charged, not more. you're damaging the poles or terminals or something I can't remember fully when at either extreme. all you achieve is a shorter lifespan for your battery.
discharge it until it turns off but never until it can't turn on again. it has a chip in the battery that needs to stay powered too.
Hello,
After reading alot of reviews about the s7 edge battery life i decided to get it. so i got 2 days ago and was really excited about it. the problem the battery is draining so fast and thats really confusing
ive seen screenshots with 50 hours and 60 hours with estimated time. mine barely shows 7 hours. today for example i left the house at 8 with 92% and now im back wth 36% left screen was on auto with wifi
and 3g and sometime gps on. is this normal? am i being paranoid? is it true that the battery will get better with more days of use?
Please tell me what should i do im really worried that its faulty or something.
PS: i did a factory reset before i use it.
Yes, it will take a couple of days for the battery to level out. Do you have the Exynos or Snapdragon processor? What apps are reporting high battery use? Have you disabled any apps?
Sorry for the barrage of questions, but all of these things play a role in your battery life. I recommend GSAM battery monitor and Greenify with aggressive doze, but I will say that 50-60 hours is ambitious. I can usually get 25-30 hours with about 5 hours of SOT. That is with a combination of wifi, 4g, gps and Bluetooth on (android wear), some gaming and facebook, instagram, etc.

Hi thanks for the reply, yeah its my fault i forgot to mention some information
I am using the Exynos model in Netherlands. the screen is always on the top of the list of the battery usage. im using gsam to monitor the battery and i dont think there is anything unusual there android system on the top using 25% or something. im really scared of using anything so it wont die on me outside today i was only navigating and doing some whatsapp calls on the 3g network "not even 4g". i only disabled facebook and using nova launcher and the AOD is off also. im not sure if i should send it back... how many days are we talking about for the battery to get better? i only want somehow a good battery not worse than my old grand prime. as i said i got it wendesday's evening and now its friday and its still bad

If I'm reading correctly, you are losing about 60% in 5 hours? If so, that is definitely excessive even during the first 2 or 3 days unless the screen was on and the phone active the entire time. Can you post screen shots of you battery stats? Maybe some app is causing the problem, but is not being reported as using too much battery.
Some folks say that the different firmwares have different battery usage. Has yours updated?

ok someone told me to turn it off and charge to 100% so i dont have enough data now. but im doing a test now with pokemon go lol
the screen is on about 70% brightness wifi and gps are on and radio is off (i have low cell signal now) and music app playing in the background and now after 50 minutes i am at 89% with screen on all the time. do you think this is good or bad?
i just noticed something in most of the screen shots from other people gsam shows about 3.80v near the temperature but mine show 4.07v does this makes any difference?
That sounds normal for an hour of paying Pokemon Go. It's pretty battery intensive. That voltage is just the current battery charge. It'll drop as your battery percent drops.
