My batter seems to go from 100% to 85% every day in a very quick manner. However, after that, it slows down. Maybe it is just the behavior of this battery (or the software that measures it).
Regardless, even with that, I get 12-14 hours (with moderate usage) before I get the 15% warning.

I noticed that as well, ill keep a close eye on it again today, i do have very heavy use

spare parts is helpful as well

If you're running a 2.1 ROM:
Don't forget to change the Network Mode to "CDMA Auto (PRL)". Do this by dialing "*#*#4636#*#*", and then pressing Phone Information. Even if it is already set to CDMA Auto (PRL), press it anyway.
Try using a 2.1 with a tweaked memkiller. It'll help to kill off apps that are still running and using battery. I usually get about 2 days of battery out of my phone while using TrevE's MOD.

I think the battery discharge curve that dictates battery level is off in the 85-100% range on these phones.

if you charge over night first thing in the morning do something to get it down to 99% then plug in charger again, i find my phone will charge for a good 15-20 minutes and the battery drops much slower

Unique Battery problem

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?

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.

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)

@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?

battery problem kyrillos Rom

i use the latest release, 3.3 version and my battery drains in like 10 hrs of normal usage...
the worst part is that upto 95% of battery is consumed just by display?
i used to get 2 days of battery backup previously on the official Rom.
i tried re flashing kyrillos Rom yesterday and i still get the same problem :’(
is there something i am missing?
or should i wait for atleast 1 week after flashing?

I don't know, but you can also install Juice devender from the market
I like that app. Now the battery has a longer life: 2 days.

The battery seems to be a problem indeed with our devices. Mine was on 5% for 12hrs yesterday.
I've read advice from Lestat, I think, to charge the battery completely before flashing.
I've yet to test it though.

boom....battery at 60%, 25 hours and still.running ( but can only say its because of this when i get home....because right now my cell phone is in airplane mode)

thanks
i think i know why i am loosing battery very fast

It may have to do with cpu scaling also.I installed cpu master and saw that the cpu is always on 667mhz and not down-scaling when not in use.

clarkkov said:
This depends on the network you use, but you can set your phone to use only GSM network or only WCDMA network in the Mobile network settings, if you are located in area where your network switches constantly because of a weak signal your battery will drain itself because of constant refreshing and switching between GSM and WCDMA networks. WCDMA (3G) network uses more battery even if not switching.

Thanks, mine is set to GSM only, since i don't use 3G..
I tested my phone again now for the past two days and found out that it comes for like 20-24 hrs in moderate (daily usage), which is ok for me....
the battery first reduces to 80% in the first 1 hour (even with minimum usage, don't know why this happens), and then it stays at 80-60% for like 15-16 hrs...

I got this problem in Kyrillos 3.0beta version...but now in 3.3 its fine...i can use mine till 2.5 days...widout task manager!!! :-/ i dunno...!!! Juicedefender works cool for sum ppl!!!! the oder solution try Indroid 3.0 - it has better battery backup!

clarkkov said:
You should callibrate your battery with one of the callibration apps, or charge to 100% and then delete battery stats file manualy. Then discarge your battery completely so the phone switches off. The next cycle should be better. Those first 20% percent do go faster than the rest of the battery.

After calibration one more cycle will be short. The next cycle will be at least double battery life. I get 30+ hours with moderate use (wifi, calls, sms, light games with GSM non-stop) now. I can also recommend Juice defender as an aid for battery conser ation. setCPU doesn't help.

still 30 hours isnt enough, its roughly a day.
With 2.1 original firmware and data activated all day i could get 50hrs minimum of battery life.
I'm done with this phone, done trying different roms, calibrating batteries, charging and discharges in less than a day.
i think this phone rocks, except its battery life sucks!

ICS Upgrade gives you a shorter battery life ??? Read how to get long battery life

Hello friends,
Here finally I upgraded to ICS and honestly I get great ( huge ) battery life..
before also I get upgrade and i get very low battery life because of low calibration of battery without my knowledge..
so I've reverted back to gingerbread 2.3.5 and I'm happy
But who wants older version when the new shiny and superb upgrade of ICS is there anyone ???
So finally I upgraded to ICS and after many searching ,, finding ,,, reading and confusion with doubt The great battery life will be came out from our Loving SGN.. so please do not get disappointed just see below.
Really here I provide you some small and very easy steps by using it you will be definitely be happy with your ICS upgrade ..
you doesn't have to go anywhere and doesn't have to buy anything with your valuable money ..
Really happy
Then read it and get longer and more juice from your battery..
you have to follow some easy steps below
1 . First upgrade your ICS from any source whichever you like ... by kies air or Kies on PC or mobile odin or Via PC ODIN [ please do full charge of battery before any upgrade low battery can make your phone unusable or dead you can get more info on other threads ]
2 . Hope you have upgraded successfully.. then use your phone till your battery goes down to 5 % or below...
[ Caution ] Do not use it till it switched off automatically.
3 . Plug your charger and charge it till morning if you are charging at night or else charge it around 6 to 7 Hours even after full charged .. it's important step.. Do not Ignore it ..
4 . and then use it as per your requirements till battery shows 5% or below
5 . Repeat the step 3
6 . Do it around 8 or more charging cycles.
You get really miracle after 3 or 4 full cycles...
[ caution ] do not overcharge after that i.e just do 6 to 7 hours charging for around 5 - 6 cycles ... after that charge till battery shows full charge i.e around 3 - 4 hours. do not overcharge ..
made it habit of full charge cycles if you are comfortable with it. it really gives great battery life then average battery life.
Hope It'll be helpful to you
Regards

It is better to charge randomly than doing full charges every time on Li-Ion batteries.
Doing full charges every time on Li-Ion will result in battery being end-of-life faster...
Overcharging is also bull****. The phone automatically stops charging the battery when it's fully charged.

As per research the full cycles of Li-on battery gives good hold of charge and also batter life..

in all honesty your post is as useless as mine right now.

According to me, It can be considered as myth . . If the battery needed to be calibrated then it must have been official.. n 2ndly the procedure above is not professional at all... So dnt even think it wud work.... Neways someone can always try and authenticate...:thumbup:

Doing full charges for calibrating the battery: no problem if you do it once in a while
But you are suggesting people to ALWAYS do full charges on their Li-Ion battery...
8-10 cycles after eachother is too much as well. 2 charges will be enough.

thanks for more info bro
maybe 2 is enough but in many cases it'll be not...

Why do you need to do this just because the OS has changed? And if so then why is it not require on GB?

Also, never let a battery dry for long periods, it will be damaged beyond repair.

It's essential because all the states of your battery will be wiped in most of the cases while you upgrade also it's helpful to you if you upgrade your ROM.

ok bro try this procedure and also report us..
In most of cases we have solved this issue with this procedure even i had this issue before now it works like a charm.

I did several full drain and full charge cycles when I upgraded to ICS. Still got the battery drain bug so I think its more luck than anything else if your battery lasts.
In my case I've discovered that power cycling the device after charging is the most reliable approach.
Install CPU Spy, run it after a charge, reset the timers, and then leave your phone in standby (screen off) for 30s or so. Unlock the phone again, and check CPU Spy - if the 'Deep Sleep' cycle is unused then do a phone restart. This has worked EVERY time for both me and a friend who I told about it. I'm getting similar battery performance to when I was running GB!

Battery life depends on a lot of things, ROM version is not the main thing.
This is my setup:
ICS version LQ3
Speedmod 3-3 Kernel
Disabled a lot of Samsung stuff (Readers hub, social hub...)
No automatic sync of twitter, e-mail, etc
I get pretty much zero battery drain when in deep sleep mode.
Of course when using the phone, screen on, Wifi On, autobrightness... battery usage is bigger and you can drain the battery in only 4 hours if you go for it.
Be careful with:
- Live wallpapers, I've seen cases where they remain active all the time
- Apps syncing data on background every few minutes (facebook, twitter, etc)
- Apps uploading a lot of data on background (google+, dropbox..)
- Games that crash and leave the CPU in a high power state until you reboot

Agree

I am agree with this reply.
If you want to get best battery back-up;
Disable all apps which are working in background, sync n update really eat the phone battery.
I am using my note with active mobile network or wi-fi for a whole day and playing games too without doing this F**KING trick.

The only way battery life gets sucked of Galaxy note is if it doesn't go into deep sleep when not in use.
To all those reporting low battery life: How much battery do you end up losing overnight. ( approx 6-8 hrs)
I typically lose <5 % ( best case scenario has been 1 %)
I had a problem last week and lost 30% overnight and found that it deep go into deep sleep.
and the best solution i found in another thread was to unlock the phone before unplugging from charger
Simply try it: For me normal time between charges is 36 hrs ( battery is near 25% level)

Fix For Battery Jumping Around

1) Charge ur phone while off untill u reach 100%
2)Remove the battery but dont unplug the phone from wallcharger
3)Reinsert the battery, you will see 0%
4) Let the battery charge, when reach 100% power on the phone without unplugging wallcharger.
Now should be all good

you are kidding right ?

This is the one of the worst advices I've heard..... Overcharging the battery is dangerous.
It will actually degrade the batteries performance

I don't know what to say. Does this work?
Also by battery jumping do you mean those crazy drops between reboots or just drops due to lack of deep sleep?

Btw the drop between reboots

Battery bin tracks the battery usage giving an estimate of the charge been used, battery .bin gets wiped every time it get to 100%, and the tracking of battery's current starts
As I remember lithium batteries charge in two cycles
1- constant current
2- constant voltage near the full capacity.
But then if you trick the phone to read battery as 0% then you are sending more current to an already full battery overcharging.
The jumping of battery percentage is because a bug in the battery "gauge"
But as always if in wrong, my apologies and I'll be more than happy to read your source.

Biggest issue is that the battery has a very poor C-rating, and has huge voltage drops under heavy load. The reboot battery problem comes from this; when you reboot your phone, or other times as well, the heavy usage spike drops the battery voltage down. Android system them detects this low voltage and just assumed the battery is almost empty. Normally there is some averaging going on to remove these spikes, and even then the battery % only goes down, so when the voltage recovers it just shows the same % for longer. Problem when rebooting is that it only sees this low, under load voltage and acts accordingly.
If the voltage isn't low enough so the phone shuts down, you might get 30minutes of screen time while the battery is showing 1%.
My problem is that the last 14% of my battery lasts under a minute before the phone shuts down. So I just treat 15% as actually meaning 1%.
Also, you can't dangerously over charge the battery, it has protection circuitry built in, and the li-ion charger part will detect the real voltage. This "supercharging" does however cost some long term lifetime from it, so it shouldn't be done too often.

Please excuse me, this is long.
Hello guys. I need some advice. I use I9195.
From the past 2 weeks i am facing serious battery drops
while phone is in standby.
I must mention that in the last 2 months my phone accidentally dropped onto marble floor 4-5 times.
Each time i checked to see if everything was working and everything did. But from the last time i dropped i began to notice this battery drain.
I made sure all hardware is working.
No problem with display even after all those drops.
(only minor scratches)
Earpiece, 2 cameras, speaker, mic, wifi, bluetooth all work fine. Network quality is great. This is the behavior with any rom, any modem and any usage.
When in standby, battery drains upto 2-3% every hour.
No background apps/services , wakelocks or anything that keeps device awake. And yet the drop is steep and is solely due to "cell standy".
I have no screenshots but here is a scenario :::
From 98% to 33% in ,
16hrs usage, 1hr33min awake and 1hr16min screen on.
Wifi enable half the time and 3g data was disabled.
EDIT :: New battery did not solve this drain.

Hey guys. Please suggest what should i be doing.
Read post above. Can new battery help ?
Thanks. [emoji29]
