Just had a thought about battery life

Ok. I was responding to a thread about my phone and no reboot's. I notice that some else posted they charge there phone with it off. When i first got my phone I charged it with it off the very first time. Has anyone else done this and not had problems or done this and it still bad battery life? I have had mine unplugged since about 5:30 am and at 7:08 at 38 percent in the staus menu.

ive done the full dead to full charge (plus one hour of charge time)
i get 14 hours of use usually and thats heavy use
people need to realize this is a DUAL core phone its gonna eat battery (especially with stock drivers/software)
dont like it go back to your razor......
( there are MANY MANY MANY HELPFUL TIPS ON HOW TO PROPERLY CONDITION A BATTERY PEOPLE SHOULD USE GOOGLE!!!)

Hey sorry for the confusion but it was not a helpful tip. I was just stating my specific way i charged my device, but your right it is a dual core phone. I hear the thunderbolt has pretty bad battery life LOL

Unfortunately, as far as I know dual core is supposed to mean better battery management.
So there's that.

Yup, I know that most would say companies only advertise that as a ploy to sell more devices, but theoretically it really should be true.

Which leads me to believe, as others have stated, that it is most definitely in the software.

I agree, especially after reading Chris Soyars' post about the battery driver. Not only does that mean our reading of the battery is directly affected, but it also leads us to believe that other drivers on the G2X could be poorly coded as well.

The battery life is ridiculous
Honestly I"m coming from a Sony Erisson w810i dumb phone due to lost of my Samsung Eternity 6 months ago. And I have to admit that it was worth waiting for this phone back when they announced at CTIA. I was so close to jumping onto the mt4g, but this unbelievable phone totally held me back. After waiting and suffering for 4 months from my dumb phone I finally got my hand not only on my first android phone, but also a dual core phone. Man this phone is blazing fast without any lag, going from apps to apps. Once I got it out of the box, I noticed the battery life was around 30%. After playing with it for about 30 minutes, it completely die out. I charged it while I was doing the factory reset. After the reset, I turned off my phone and left it charged 8 hrs while it's off with the battery charging screen. Waking up at 9:00am, it was 100% completely fully charged. Left the house to school and at 12:30p.m, it was down to 5%. It's been only 3 hours and 30 minutes! Before the battery started to drain I had wifi, syn emil, bluetooth and even brightness on low. Also, I had GSM/WCDMA on Auto, so that wasn't the cause either. My second attempt charging cycle to full battery, well see how it goes. If the battery doesn't last me over 6 hrs, I'm definitely going to return it for another new one. I'm having a bad impression on my first smartphone and I will do anything I can to get it the way it should be. It just unacceptable and ridiculous. Oh by the way, my phone is not yet rooted or done anything with it beside downloaded few apps and games. ^__^

i had this issue last night when I plugged in my phone it showed charging and 38%. woke up this morning 8 hours later and it still showed charging and 38%, I'm thinking what the f, this never happened with my nexus one. so I plugged the phone into another outlet and used a different charger and left it for an hour and it still showed the same thing. It wasn't until I restarted the phone that it showed 100%, but I find that odd. don't have the slightest clue why this happened.

I took my friend to a T-Mobile corporate store to show him the G2x I bought. I bought mine through TMO Loyalty so I had to wait for it to ship.
Anyhow, there was an LG rep there trying to showcase the G2x and G-Slate and I asked him how the battery life is for the G2x. He told me 6 days on standby and about 5-6 hours of continuous talk time.
I'll check to see if he's still there and take a PTO if I need to, to be there with him and call my office and let them put me on hold and see if the phone has enough juice to make it for 5 continuous hours.

Unfortunately tmo decided to add some apps that run by themselves....after I deleted them I havnt had any apps open without me opening them.....I get about 20 hours wth a lot of use. This is the best battery life I have gotten on any android phone

I don't see how to get 20 hours out of that battery! Are you on edge? any live wallpapers? Account syncing?

Love my G2x, But the battery is worst ever.

Have had my rooted stock rom g2x since day 1.
Love phone. I am comming from H2 customed. I thought it had worst battery I have ever had.
That was till the g2x. I hate running a task killer. But am about to do just that to see if I can get anymore battery,.
Its to the point where I fully charge phone and yesterday with only 12 minutes of talk. Maybe 20 minutes of Web use and some emails. Battery was yellow.
This is a joke right? My only thought is that by having my Gmail auto refresh every 10 minutes possibly that could be some cause. But I if not in my car to keep on charger phone last barely a day.

Sounds like you have a bad battery, I get great battery life with the phone
G2X & Nexus S

I get 13hrs on this battety with wifi on all day.

Did u calibrate?
Sent from my LG-P999 using XDA Premium App

do u really think that is the standard performance of the G2x battery or is it more likely you got a bad unit ? Come on now people, stop posting this crap and just exchange your phone when you only get an hour of battery life. Why start a freaking thread ? You could have used that time to go exchange your phone.

Totally true.
For those of you with problems, your phone is still new, it will be replaced either under buyer's remorse (15-20 days) or directly through tmobile after that period.
Just get a new phone and be done with it.
My first hot potato of a phone would get good battery life, until it cooked itself alive. My second phone was on for over 27 hours and was still at 50%. I'm still surprised.

First off guys. I am not a newbie to XDA or phones. No its not a bad battery.
Remember I am the Costco Manager so I can exchange phone as much as I want for 90 days.
This is my third as I wanted a perfect screen.
I have had this problem with all 3. So the battery is fine.
I use batt apk and I show about 5%loss per half hour after taking off charge
There is no way this is normal. Now I do have lots of apps. But I have froze some in Titanium. However I can blow out this charge in an hour with web use.]
No I did not calibrate. Did not read that till after. However I did charge initially correct.
My HD2 would gobble batterys. But this phone while I love it. Is not a great everyday use phone if not able to be on a charger during day.

Huh.. some people are getting awesome battery time. When it first came out, people were having success with doing factory reset on their phone. Idk.. I personally didn't buy it.. but they swore it worked. Give it a try.

So what you're saying then, is those of us with good battery life are the ones with the bad batteries? You really didn't think this through, did you?
I find my battery life was OK on the stock ROM. Nothing I'd get excited about, but I'd gotten used to insanely poor battery life running CM7 on my vibrant. Since I flashed the GB leak (no wipe, fixed permissions, erased battery stats) I'm seeing 18+ hrs with moderate usage.

gingerbread in general gets good battery life, cm7 for galaxy has problems due to samsung not following the google standards, those guys are basically shooting in the dark with that project, yet they have made huge improvments. recently people report decent to improved battery life on the latest builds.
to the op, what are your sync options? i find facebook sync and facebook contact sync are big culprits. also i only use google contact sync to get my contact list initially then turn it off. also if you have your gmail on the stock email app and the gmail app it can increase useage, if you prefer the email app id turn off google sync all together, if you like the gmail app id turn off fetch on the email app.
another culprit is weather apps using the location service, for me beautiful widgets is a battery hog on a vibrant rom but not on a captivate rom so results can vary from phone to phone.
and last of all i dont agree with calibration proceedures, i get some funky results with them, i just delete batstats and then charge to full. i find it takes 3 day minimum to get a good calibration, 5 days is sometimes needed.

I get very good battery life with mine and have been since day one. It lasts almost twice as long as my Vibrant and N1 did.

I use juice defender to turn on/off my data for me when its not being used and the screen is off. It seems to work less than on vibrant.
I'm running stock rom and my battery life varies TREMENDOUSLY from when I'm at work and seldomly using it to when I'm home surfing the web on it ( tablets too far from couch I'm surprised I got the cookies )

I was getting really bad battery life when I first got the phone (about 7hrs ) I ended up finding out that the touch led notification app was the culprit so I deleted it and also calibrated my battery and now my phone last all day easily and that with me playing guerrilla bob and the samurai game at work for like 2 hours lol
I recommend you download the where's my Droid power app from the market and see what's killing your battery

Also keep in mind that it could be a certain app draining your battery. I downloaded the NFL apparently for draft day and even after exiting the app it took my battery down 15% in a matter of 10 minutes. Not to mention it had my battery's and CPU running super hot. On average I get about 12 hours out of a full charge with moderate to heavy usage.

My last charge i got 36 hours of light use so I dont know what everyone's problem is lol

No wonder your a newbie and no listed thanks. What an asswade comment.
NO!!!!!!!!! What I am saying is that is has to be an internal issue with either synch times or possibly an APP be it internal or external that is causing MANY of us to have terrible battery times vs. others with good. Not saying anthing negative about those who are functioning ok.
I have been rooting and modding for 2 years. This is the worst battery usage yet. My Galaxy S 4g. Could last with same synch times and apps for 18 hours.
Now for those others who have there head inserted other then in there behind.
Okay ran some tests today,
1. Charged phone to 100percent.
2. Left everything the way it has been and no adjustments.
Battery at 84 Percent sitting tableside no text, app, wed or voice use after 2 hours. After 4 hours at 64 percent. After 6 hours at 51 percent. After 8 hours at 39 percent. This is with no usage. This is terrible.
Okay, Now have done following based on others test here and other forums.
1. Loaded Setcpu and made profile for sleep using stock 216 usage.
2. reluctently loaded Taskmanager Pro and killed all but needed apps.
3. Loaded Battery calibration app and after charge calibrated phone.
Left my email synch at every 10 minute as its needed for work.
We will see if this brings better test times now and report back.
What may be my culprit from studying this and other forums is I am in Seattle. We are Tmobiles home office corp and full test market for 4g and every change before rest of USA. I get full 4g at all times. In fact my speed tests are off the board. ave of 12 down 1.3 up speeds.
From what I am finding out, those of us in best 4g coverage (and Seattle is listed best) are finding much more drain on battery in standby and in use.
So my theory is that with this phone and its dual proccesor and my 4g, this is why myself and others in like markets are seeing much faster drain then others. Some dispute this possibility. however other experts say its fact.
Will report back findings tomorrow.
Thanks.

May be some of my issue vs. others.
I do have sync on for FB and Google mail 2 accounts. and I use Fancy Widgets for my Weather and news feeds. However I also used these on my HD2 a known battery hog running cm7 and it had even better life then the phone. I run them on my other Galaxy s 4g as well and it has awesome battery life.
But I will freeze these in my next test after running this test.

those are shocking results man... I dont know what to tell you... If I literally dont touch my phone for 6 hours i will drain no more than 10% of my battery, closer to around 6 or 7% based on my battery monitor widget...
I pulled the phone off at 6 this morning and didnt touch it until 12 and I was at 92%... Chelsea got ****ing spanked this morning and I got a barrage of **** talk text messages that I did not want to deal with haha so my phone wen untouched for a good 6 hours...
I will say though, when I first got the phone my battery life was pretty wonky... first drain was great, second one was mediocre, the third and fourth ones were horrible, drained in 6 hours flat of light-moderate use... I did a factory reset at this point to try and change things up... Calibrated once after that and I have run it up and down to get a good read and I have not looked back since, like i said i can get 20-30 hours of moderate to light use no problem at all!

Great battery on my g2x
I had battery problems with my G2x, only lasted about 7-8 hours on moderate use and cell stabd by was like 50% of battery use.
After i installed the leaked official Gingerbread ROM is like a new phone, ofter 16 hours of use i still had 43% last night. In idle mode it uses about 1% in 2 hours.
I think the battery probles come from Froyo not getting along with the dual core processor.
This phone is awesome!

Iceshark, you're not crazy. This is the same exact battery drain I get not even touching the damn phone! This is my second phone in less than 2 weeks, the first had the same results, both brand new.
Today I unplugged my phone at 12:45 pm, gave my mom a call for mothers day (less than 2 min talk time) Got to work and browsed web for maybe 5 minutes then clocked in at 2 pm. Took a 15 min break at 4pm battery was down to 80% (did some web browsing for 5 min). Took my 30 min lunch at 6pm (battery was down to about 60% (did some browsing for about 15 min). Took my last break at 8pm, and battery was down to 30%. I clocked out at 10:30 and I only had 20% battery left. The only timeI touched the phone was on my breaks, the rest of the time my phone was in my pocket. I had juicedefender running on balanced.
It's now 12:01am and I only have 14% battery left, that's not even 12 hours yet, and I only used the phone and it's features for less than an hour, all the other drain was sitting in my pocket. This is unacceptable. And I'm starting to think all the other people who claim to have great battery life are exaggerating or lying through their teeth.
Although I did a test yesterday using auto airplane mode, which automatically enables airplane mode when the screen shuts off, disabling any data, and then it turns data back on when you unlock the screen this helped very much with battery draining and at the end of an 8 hour work shift I still had 70% battery, but without data you can't receive calls, which sucks.
This battery drainage or bleed while the handset is not even being used needs to be fixed. And isn't it false advertising since the G2x specs indicate standby time is 400 hours?

Battery Life, Oh?

I think it's crazy how many people are downing the battery life on the Sensation. I used my phone a bit today. Off the charger at 10AM, used GPS to go to work with Bluetooth activated as well. Forgot to turn them both off while at work. I used my phone like ever 5 minutes checking Twitter updates(also weather/news/facebook/email/etc updates are automatically updating as fast as the app allows. So quick updates for all my apps, GPS and bluetooth turned on all day. Home around 5, watched a few episodes of South Park on Netflix with my phone. Read some news. Played a few different games for about 5-10min each just trying out new games. It's now almost 1AM the next day, and I'm above 40% battery life. I manage my screen brightness, that may be the only thing I remembered to manage well today. While outside/in car, full brightness, inside, as low as possible.
It's shocking to me when I see threads of how the battery life stinks. I'm using the stock battery, I don't even seen the need of getting a larger battery because this already gets me through a day full of activity. Anyone else find the battery life on this device, quite handy? Mine is rooted, but it's stock ROM. I'm also using a skin posted by a member of our forum, the transparency. I'm running the stock T-MOUS(why is it called tmous..? are people that lazy to spell out t-mobile?) ROM, because I accidentally deleted a few apps I discovered I needed back, and did not do a backup. Oh, and I'm also using the battery mod, for the battery icon in my notification bar.
I guess I'm just praising the battery life, is all

I have only had my sensation for about 5 days and battery life is amazing! Im still stock too.. I came from an evo 4g rooted running cm7 and or miui and battery life doesn't come close to being as good as my sensation. Not only is battery life awesome, this phone is awesome. I moved to Southern California a couple weeks ago and Sprint out here is horrible.. so I switched and couldn't be happier. Plus I like this phone was better than the evo series. Battery life is sweet!

You would have to post a screendoor shot of your battery usage and screen on time to completely determine how much the phone was used and how long the screen was on.
Bluetooth and GPS don't use any battery or have low usage (depends on the chipset because some completely turn off) during standby since they're not being used at all.
So we can all praise our phones for having good battery life, but it all depends on usage. If you don't use your phone a lot (you could turn on your screen every 5 minutes but at the end of the day have only like 45 minutes of screen on time and like 70% battery left.) Then you get good battery life. Use your phone a lot and quite simply battery life sucks.

I think it can largely depend on how you use your phone, not just how often or for how long. For example my Fiance also has the Sensation and on her first charge she got 3hrs52minutes before hitting 10% battery. Since then she has only gotten ~2hrs each day now that she has Twitter and Facebook for Sense accounts set up.

That's not good. There's gotta be something wrong with either her phone or something. 2 hours of battery life warrants an exchange.

The phone lasts longer than 2hrs, that's 2hrs of the screen being on. my sensation get's about the same. This is with Gmail on Autosync and Twitter/Facebook for Sense accounts enabled too.

If I do what u did, my batt will be flat in 6 hours. Somethings just not right with my sensation.

You can go by statistics and on screen time and what not. but I just got home from work, and I literally used my phone for about 2 hours straight calling carriers for a customer. I'm above 80%. So from 9AM-4PM, only saw a 20% drain. Once again, keeping BT and GPS on just to see how it goes. ALL of my autosyncs are once again, on, and set to the most frequent can be.
Compared to any other stock phone, this is amazing. Compared to my Cyan N1 and my Cyan NS, it's not a huge difference. Although, at this rate I may give the lead to the Sensation, since I'm leaving all these extra features on throughout the entire day.

good
I get two to three days out of my Sensation, and I'm a relatively heavy Internet user... don't phone much.
At first I wasn't getting great mileage - having to re-charge after only 10 hours or so, but did two things to improve it dramatically...
First, charge the battery once using the following method:
1. charge battery to 100% and leave on charger for an extra hour
2. unplug the cable, turn off* the phone, and plug the charger back in. leave charging for another hour.
3. unplug the phone, turn it on for two minutes, turn the phone back off*, and plug in the phone again. leave charging for another hour.
* when I say "turn off", I mean completely, without fastboot. so either disable fastboot before switching off, or turn off the phone and pull the battery then put it back in.
Second:
Turn off automatic screen brightness, and set the brightness manually to what you need. Ideally, I'd like to have an auto-screen brightness adjustment that automatically sets it, say, 25% lower than what the built-in function does.

That's pretty exceptional. I usually get 13-14 hours with 5+ hours of screen time before I'm at 20%. Using the chichitec battery, btw.

My chichitec battery went 18 hours yesterday before it got to 10% and I charged it. That was with a lot of web browsing, some phone calls, music, games. Id say, medium-heavy usage.

Same here I have had several Android phones with different carriers and this is hands down the best, on par with the iPhone I had previously with Verizon. No problem getting through the day with Exchange and 2 IMAP accounts and heavy phone use, the only mod is I set screen brightness, battery is stock.

no one is complaining i watch sparticus on netflix and game of throne on hbo go for 5 hrs straight while facebooking random hoes . and i am out of battery..
we are complaining that the 4g drains the phone while on idle.

this is the best battery life i've ever had on a phone. i can't complain at all... i even have gps on and i could never do that before. lol!

Guys, having GPS on doesn't use any battery. It only uses battery when it is active. So for most of you 99% of the time your GPS is off aka standby or whatever you wanna call it.

One reason many people complain about bad battery life is that it seems some Sensation models are actually faulty. Best evidence: TechRadar review.
http://www.techradar.com/reviews/phones/mobile-phones/htc-sensation-943466/review?artc_pg=9
UPDATE: We've finally managed to get our hands on a new review model of the HTC Sensation, and the good news is the battery life is definitely improved.
It seems that a combination of data-hungry applications and a slightly dodgy model caused the odd readings from before, although we're not entirely convinced the above scenario isn't one power users will face, which is why we've left it in.
But in normal use, and by that we mean sending 42 texts, spending 49 mins on the phone, watching an hour and bit of video and using the music player constantly, plus a few minutes spent using GPS to track ourselves and browsing the internet for roughly 45 mins, the battery pretty much lasted the day, although it was often in the yellow zone come 11PM.
However, what was more impressive (and a relief) was the sleep state of the HTC Sensation. Where before the phone would get very hot and start spewing out battery life in our pocket for no reason, if you leave the phone locked up for around 10-15 minutes on our new model the power consumption dropped to almost nothing.

[Q] defective device or battery

friends and gurus
i need your help in deciding if something is wrong with my sensation 4g or is it something else i am doing. the main issue is that battery life sucks. the first sensation i got also had the similar issue, and i exchanged it for the new one. but i have the same issue. i have went thru at least four cycle of draining the battery and then charging it up. also did the battery calibration. i haven't rooted the phone. just using go launcher ex instead of sense in hope of getting more battery life. so, now my question is is it just my bad luck with sensation? should i try one more time in exchanging device with t-mobile or should i go with HTC service?
will appreciate any help.
this is a detailed log of today's observation.
HTC battery level
took of from charger : 5:00 AM
7:00 AM 89% --browsed net for 10 mins, checked emails
-- played music for 5 mins
10:00 AM 50% -- made two calls total 5 mins, recved two calls total two mins
11:18 AM 36% -- played game for 5 mins, checked email couple of times
11:44 AM 33% -- call of 1 min
12:37 pm 25% -- no use
01:17 PM 15% -- placed a two min call.
02:00 PM 14% -- at 15% phone went into power saver mode and it turned off wifi as well as mobile data.
02:40 PM 5% -- now can't wait, plugged into charger :-(
what is using battery
display 47%
cell standby 14%
phone ideal 12%
voice calls 12%
wifi 11%
internet 3%
bluetooth 1%
what is running on the phone
stock mail client -- one work email
gmail -- one personal account
juice defender
go launcher ex
sense clock widget
go weather widge (no auto update, update when opened)
wifi -- on
4g mobile network -- off
bluetooth -- off
GPS -- off

It is easily one of the two... Try factory reseting the phone if that has no effect, id just return for a replacement
You could also s-off your phone and look into some of the roms in your region, could also be helpful :|
http://forum.xda-developers.com/forumdisplay.php?f=1112
With my phone personally...if i charge phone to full at 5am..its full at 7am
(Currently using Stock Rom/Kernel used ADB to pause applications runs like a champ!)
Best of luck with your issue

thanks for your reply. but why it need factory reset? i got phone just a week ago. i have installed few apps like unblock me game, juice defender, battery calibration, volume control+
(underpower speaker is another issue). , google maps, go weahter, go laucher.
the phone i have is made in china and manufacturing date is 7/2011.
s-off phone will void warranty, so i will wait till warranty period is over.

snap!
seems to me that your getting pretty much the same use from your battery that i am. i had the htc desire prior to the sensation and to be honest the battery life is comparable. i was expecting the sensation to be better battery wise but but i guess duel core is desire on speed so will use more power sucks though, i just plug phone into charger every night. don't think changing the phone is gona help.....battery life on htc is just bad. maybe buy a backup/second battery.

i will be more than happy if i have to charge phone just once a day. it drains out by 3:00 pm, then it is a real issue. That too without any long calls. i am sure, if i talk for one hour, then battery will die on spot.
the usage of today is in fact much less than some busy day. i am inside my office so have used landline/ skype for calls. if i have to be outside my office, then it gonna be a problem.
on a side note, what good alternative to sensation is there with T-mobile USA? i have seen some amazing battery life with iphone 4g and motoroal defy. and my own blackberry could go on for two days without a need to charge.

I too have been very frustrated with battery drainage. But for me, it didn't get bad until after I flashed modified ROMs. And I am not ignorant to flashing ROMs and I have done everything I can to find out the battery problem (battery calibration, bump charging, proper RIL files etc). But I can not get more than 8 hours in a day for any ROM. And these ROMs proclaim to be better on battery usage.
When I was on stock, I was getting 24 hours with moderate usage.
The thing I do not understand is that some people brag about their good battery usage and others with the same ROM are getting bad drainage. There are so many variables to battery drainage that trying to understand the problem proves difficult.
So I am just as dumbfounded as you.

How often does the mail client poll for new mail?
Do you leave your wifi on all the time? And if you do is it always connected, or just on and sometimes connected? When its on but not connected it will scan for available connections very frequently causing drain.
How is the is the mobile service in the places where you spend most of your time? If you spend a lot of time in places where the reception is poor then anytime you have no service the phone will search for service causing drain.

I am next to router all the time . As for mobile signal I usually get 3 to 4 bars. Email client is push gmail client as my company is using Google business app. Even if I dnt use the phone, it drains about 5% battery. If I use moderatly then all bets are off.

Since I have a similar battery problem and have done hours and hours of research including testing various ROMs, I think the answer to this strange behaviour (some people with good battery life, some without) is indicated by TechRadar's Sensation review:
UPDATE: We've finally managed to get our hands on a new review model of the HTC Sensation, and the good news is the battery life is definitely improved.

I was going to switch to get a replacement model today since I'm still within my "grace" period, but something strange happened yesterday.
After trying out loads of different custom ROMs which all made no improvement to my terrible battery life, on Saturday I went back to the stock ROM (although the 2.3.4 version which is not yet out in Ireland), and on Saturday I suddenly had decent battery life (i.e. lasted the whole day and more)! Saturday night, still planning to return my phone on Monday (today) I switched back to the 2.3.4 stock ROM and put S-ON back on for warranty purposes. Then Sunday and today I still have the acceptable battery life of 1 or more days with light usage!
So, still have to do more research.
But simple answer:
Just get a replacement and hope you get a "working" model; otherwise, ask for a SGSII.

well, this is my second one. and i also have the same observation, after upgrade to 2.3.4 , battery life seems to have improved (OR is it just a perception? ). I have got much talked about anker battery, and just put it in. let it go thru couple of charge-discharge cycle, and then i will comment.

How's the Anker battery? I'm getting mine tomorrow hopefully Bought a spare which I'm planning to resell internationally in case someone wants one (difficult to buy outside of UK or US for reasonable price)

i have been using anker battery for last few days. looks good so far, it lasts a day. It works great with wifi, but using data on 4g (TMOUS) drains it a lot faster.

This has helped my battery

This is pretty dumb and could be just me but ill put it out there anyway. My drive to work is about an hour each day. From the time I wake up and get to work its about an hour and a half. My phone would be fully charged when I left my house and end up mid 90s when I get your my job. Maybe low 90s on some days depending on how much traffic there is. When I get to work, my phone seems to die pretty quickly. My job is pretty boring atm so I am on my phone a lot.
Next though. My phone is unplugged for about 20 minutes before I get in my car. Always goes down at least 2 or more percent in that time. But now lately I've been using my car charger on the way to work. Get it fully juiced again even from such a little drain and sometimes it seems like I get double the time from that extra charge. I use the charger it came with at home and bought like a $10 car one from amazon.
There's no proof to what I said but it's been helping me. I was on synergy the past few weeks and just switched to team insomnia last night. Hope this helps someone

I have no idead what that your are trying to say. Switching roms helped you? Or a different charger?

I know what your talking about and I have the same experience just with the home charger, ever since I figured this out I always charge my phone at night and before bed around midnight or 1-2 a.m. I unplug it. I wake up at 9:30-10 I have about a 4% drop of charge and put the phone back on the charger till the phone says charged. Like this I have 3h screen on time with about 1-1.5h talking time. also I stream a lot of music from grooveshark/soundcloud/sirius xm and also use google music..lot of gtalk and video talk with my wifey
try it out guys and see yourself. It really makes a hell of a difference.
EDIT: @aypeeootrek he's trying to say that the battery life is better if you charge the phone wait till a few % drops and charge it again till full. (that's what I understood)

I think that's called the trickle
GS3

Or bump charging. It worked with my Dinc too.

if you are in a low signal area (inside buildings or whatever) then switch to "power saving mode" in the drop down menu.
when out of those areas, switch off the power saver.
if you aren't getting 24 hours from a single charge, then you got apps/widgets sucking up way too much power.
Another choice is buying a second battery. That way if you run low, you just swap out and have another however many hours to play.

The power saving setting really only helps when you are actively using your phone. Having it on or off with more or less be the same when it is idle. And if you get over 24 hours I could easily say you dont use your phone. A better way to judge battery life is by screen on time.

not true. i speak from experience. from battery dead at 5p to 50% at 5p.
i use my phone to talk, email, and text. i guess i'm old school. but with 24 hours and a spare, i'll take it.

24 hours? I've only got that once and I was in a 4g area and didn't touch my phone for 95% of the time. I live in a 3g area and have did almost everything to improve life. I love the days when I get 16 hours. I have definitely found that low signal is hard on this phone battery.

Ya, I am finding a lot of silly statements like the one you were talking about. Everyone seems to have an outstanding WHBL (when hit by lightning) story of how utterly amazing their battery life is, but can't show the rest of the world how they do it. What saves my battery life? I carry an external 5000mA external battery I can just throw on the phone when I am not near a charger. Another trick, I took the battery % off of my screen. Seeing the exact amount really showed me, almost too exactly, how bad the battery life is on this phone. I have felt the same way about other phones before tho, once the Jelly Bean update comes out, which, hopefully, Samsung is probably waiting to release until the iPhone comes out, will fix all of these problems.

So you bump charge it?

The post below yours summed it up pretty well

Sounds like you need a hug，good luck.

I'm about to get a Galaxy S III on Monday, I do need to get an extra battery simply because I always like having a backup battery. Do all versions of the SIII use the same battery? I know when I switched from Verizon Nexus to GSM Nexus I had to buy different batteries for the GSM one.
And yes I'm getting a Verizon S III, I switched my Nexus to the GSM because Verizon killed the Nexus experience for me, but I still have the line so I figured may as well get it updated.
