Battery draining AGAIN

So i tried what you guys suggested. I rooted the phone, bought setcpu, using anttek to freeze running services, and used the battery calibration app still NOTHING. I just woke up and my battery was at 0 before i went to sleep it was at 62%!! How can it die in idle with no running servislces wi fi off gps off BT off i mean it has to be the battery right?

I was just getting on here to rant about this. It seems that whenever I use the phone the battery gets warm and declines quickly. Lost over 40 percent battery over 2 hrs mostly playing mp3s

This may or may not be related...just something to think about. For years I've placed my phone in the top drawer of my nightstand when sleeping. What I noticed when switching to Android is if I leave syncing on it will drain my battery. My theory is...in the drawer my data signal is very week or non existent. The phone dutifully tries to sync on that weak signal...searching for signal...fails and retries...or succeeds and transfers at a snails pace. Result dead battery. I've found that disabling data before bed results in less than a five percent drop. Just my experience.
If not then I'd suggest a phone swap.
Also...Why in the world did you start another thread? If we scatter all these x is wrong with my phone posts across multiple threads it really hampers the effort to solve the problem.

I've also noticed this. In the morning my battery life is decent but by the after noon I can do light web browsing (10-20) mins in an hour and loose over 15% tmobile told me that isn't good lol I have a new battery on the way. They shipped it out yesterday we'll see if that helps. Also my battery was dead when I got my phone did anyone else get one that couldn't even power the phone on?

Yes. Like the OP, I tried the solution of the person that is so called getting 20hr battery life under medium usage. Just doesn't seem feasible at all. And its really annoying to have to cut the data off completely to keep the phone from getting warm...

If you researched the problem and tried the solutions offered, then the logical next step is to contact T-mobile for a replacement. This is an early release of a new phone; there will be defects. And you don't have to settle for a defective device/battery. I can assure you, I get battery life on par with my previous phone (8-20 hours depending on my usage)..so, bad battery life isn't a problem inherent to the phone. And my phone doesn't get warm with data usage. It sounds like you might have a defective battery or phone. If you aren't satisfied, don't settle...make 'em make it right.

I get about 5-10% battery drain overnight most nights and I am not mindfull of what apps are running or what is on. My experience obviously differs from yours. I do get great service in my bedroom where the phone is overnight. The other night I did experience a bout a 60% drop when I left the phone in my daylight basement (underground). I get crappy 2G service in my basement and it looses signal a lot. I think it adds some credibility to the searching for service slowly killing the battery. maybe try putting the phone in airplane mode before going to sleep. That should give you some indicator.

I'm now are 28 percent after 3 1/2 hrs with the display only using 13% if that..

Just curious, does your phone feel hot right now?

You might have a bad battery or something. My first g2x rebooted constantly and drained the battery and got hot.
New one goes 8am to midnight with 20% battery left, on moderate usage. And even at the 20% left i can leave it overnight and it'll still have power in the morning.

The phone is going to get warm is use because the CPU is under load and that produces heat. As long as its not overheating this is normal.
Have either of you tried the factory reset? That fixes the idle drain for most people.
Also... Your phone is going to drain battery faster while actually in use no matter what you do. The LCD and data connection are the biggest battery drain for smartphones. Until battery technology improves, there is nothing that can be done about this. But like I said try a factory reset and you should see your idle drain improve dramatically.

Were you on wifi? Because if you weren't that much drain is within the norm. Web browsing = constant data connection = more power consumption = faster battery drain.

I had 10 hours of heavy use yesterday and had 25 percent left... 2.5 of those were in airplane mode cuz I was flying from Phoenix to Atlanta but I watched a movie during the flight and had music playing the rest of the time... during my layover which was 4 hours I browsed the web, watched a stream of the Celtics vs heat for a bit, more music... I plugged back in with 25% left and had 3h20m of screen on time... this battery is freaking awesome! I had drain issues initially but they went away and now I'm golden

when i did a factory reset, my phone was getting hot until i remember about the *#*# thing and changed that to wcdma/gsm auto. then my battery life got better.

Get juice defender. Its work wonders for me and my buddies thunderbolt actually makes it through the day now

Battery Drain is mostly Cellular radio
I too am have been looking for a way to have this phone last at least 8-12 hours with normal usage, but I don't think its going to happen unless there's some major update to the radio firmware coming in 2.3 Gingerbread..
All the evidence seems to suggest two culprits... for battery drain.
- First is the 4G radio, look around at almost ALL 4G enabled phones (whether on GSM at&T Tmo or Verizon), all eat your battery, from the very beginning EVO 4g, Verizon Thunderbolt, Mytough 4G every single one of those phones has the users complaining about horrid battery life. You can confirm this by looking at the battery usage on the G2X and you'll see that the number one use is Cell Standby (that's the cellular radio) on my phone its anywhere between 35% to 60% of total power used.... on kmy nexus one it used to be the display.
-Second, Tegra 2 is more power hungry , granted its a mobile SoC but its mainly designed for Tablets and such with beefy batteries, this is the reason that the Atrix comes with a 1950MaH battery, you can try and use SetCPU to lower the speed, but I have had minimal success.
Here's a test , when you don't need your phone put it on Airplane mode, for 24hours and watch HOW LITTTLE the battery drains.. reason the cellular radio isn't on..

I agree. These battery threads are driving me nuts.
Go in the other million threads and read

The thing that is strange to me is how quickly these phones charge. It seems to go from 0% to 100% in well under an hour. Was thinking I should try charging it while off (well, screen w/ battery only).

What???? Having the phone on makes my battery drain? WTFO?!?!?!
Seriously though, I have not experienced bad battery life on this phone. Last night I left my phone off the charger, gps, wifi and wifi calling on, and when I went to bed at 1030 I had 64% battery. At 700 this morning I had 54% battery. Only a 10% drain for me overnight, or a little more than 1% per hour.
All I've done to achieve this is the following (and I realize that supposedly you no longer have to condition Li-ion batteries):
-when I got the phone, I didn't charge it but instead let the battery die completely to where I couldn't even turn the phone on.
-charged the phone overnight w/o turning it on.
-let battery die completely again.
-charged phone overnight w/o turning it on.
-let battery die completely again.
-charge and use phone normally.
I've also rooted the phone and used Ti Backup to remove most all of the bloatware except wifi calling, but otherwise it's the stock rom.
I typically get an entire day of my normal use on this phone. If I use it alot, I have to top off the battery w/ my car charger on my way home from work. This isn't unusual. I had to do this w/ the blackberrys I owned and my evo when I was on Sprint. The battery life doesn't seem any better or worse for me than any other smartphone I have owned, and it's certainly better than my evo or my wife's evo, and both of those were rockin' custom roms and uV kernels.

G2x battery life

Just wondering how is the battery life on this phone, had the chance to play with it @ a tmo store for a good 1 hour and its an awesome device ran benchmark on it and it scored really good, I was suprise it beat the G2 even when I overclock it to 1.42 ghz lol. I really want to know about the Battery life in these dual core smartphones, as I'm tempted to get me a G2x.
T-Mobile G2 1.42 GHZ

Its great.
inb4 use the search button

It really depends who you ask about it. There are a ton of battery complaints whereas I and many others find the battery life to be exceptional.

I think most of the people complaining about battery life either
A) Haven't performed a factory reset which fixes the phones constant power usage even when idle. OR went into the hidden menu and changed the radio to GSM and WCDMA Auto.
B) Have a defective battery (ie those who say their battery drains even when the phone is powered down)
C) Have unrealistic expectations for battery life all together.

Well on point C, I can say with absolute confidence that this battery is the best I've ever had out of all my smartphones (PPC-6700, Mogul, Touch, Touch Pro, Touch Pro 2, Curve 8330, Bold 9700, Palm Pre CDMA, HTC Hero, Evo, Inspire, and the Samsung Captivate) with me being able to talk for four hours and still have 30% of the battery left and then I can game for another 2 or 3 hours. Most of those phones would have been dead after the phone calls (the Captivate would be close to death, the Curve would be about an hour behind it) let alone having to power such a nice display and high-powered graphics chip.

I tend to think the actual answer is (d) the battery driver is so vastly broken that any reading it gives is essentially fictional. In this case, some people will be happy with their battery life (because their readings are fictionally high) and others will be freaked out (because theirs are fictionally low) but the actual answer is "nobody knows".

This battery outlasting my Vibrant by hours with the same usage pattern isn't at all fictional. Not saying the drivers arent messed up.. But if battery life is as good as it has been for many users already it can only get better. Either way in its existing state its still better than many android phones.

Not at all convinced that it's accurate - still saw something like a 60% drop in a few minutes, on a brand new battery.
It does seem to help the "stall" problem.

Exactly. If the battery driver reads "0" then it will shut off. That doesn't mean the battery is depleted. This explains why you'll get awesome battery if you clear battery stats on a full charge initially. It aligns the counter with the actual battery.
Mine runs from 8-midnight with some to spare with heavier then normal (thanks xda!) usage.
LG G2x - CM7 2.3.4

The G2X has with out a doubt the best battery I have ever had on a smart phone and has been since day one. I never had any battery problems but that might be because since day one I have used SetCPU, rooted my device and froze all of the bloatware including WiFi calling. I constantly get about 15 hours with moderate use and 8 hours with heavy use which includes 1 hour worth of playing games, 1 hour browsing the internet, 1 hour reading all of my RSS, 30 minutes reading Fox news and CNN, 50 text messages, 1 hour of phone calls, 2 hours streaming music or playing my MP3's and about 30 minutes browsing facebook and twitter.

Well I just asked because of the bad review on battery life on tmobile website but I will probably get the phone in august, by than it'll probably have gingerbread. Only thing I don't like about the phone is the lack of hardware keyboard especially because tmo considers it part of the G series which it doesn't fit in, and only god knows I what I would do if this phone had a keyboard to get it LOL I would rob a bank.

Unless suffering from some issue idle drain is awesome. Afraid not much can be done about the drain during use though besides turning screen brightness down and using wifi instead of 4g.
I pretty much never use wifi anymore because its so damn slow.. but hopefully that will get fixed because with wifi on battery life is just unreal even when in use.

My Battery Life Report - Feedback Welcomed

So I have been using Juice Defender Ultimate for a couple of days and also measuring stats with Juice Plotter.
My experience thus far has been that the addition of JDU hasn't really changed my stats. I would say it has helped slightly... At the end of an 8 hour day I am usually at around 65% I average approximately 4% battery drain per hour mostly with the screen off since I don't typically do much on my phone while at work. I'm sure the battery stats will improve with the addition of custom ROMs but was wondering if the 4% decrease per hour was pretty much standard across the board.
I happen to like the battery performance thus far but will admit that my Cappy was providing me with a remaining percentage of around 75% after an 8 hour day. Of course, that Cappy was on Gingerbread with a super tweaked rom that took advantage of every little ounce of conservativity. There really isn't much difference between 65 & 75 but I thought I would throw it out there to see what you all are experiencing.
Thoughts?

LMFAO! (hehe since you brought up 2000 I thought I'd give a 2000 acronym too, haha).
A++++ for the post tho, hehe

LOL @ some of these replies! Ok. I'll explain why I use JDU. I work in an area that's on the outskirts of AT&T's nearest tower. If am on the outer edges of the building, my service is so so. If I am in my office, which is more interior, my service is off & on. As soon as I walk outside, my service is decent. So, until AT&T increases their presence near our building, I will be faced with a dilemma. The radio on the phone will struggle to lock onto a signal all day long. Depending on where I am in the building, it can get really bad. This constant effort to acquire signal equates to increased battery drain. When I first purchased the Infuse on 5/20, I went back to work that afternoon and my battery had drained from 100% to 40% in less than 4 hours. I had experienced this with my Captivate so I knew it had to be the constant struggle to obtain signal.
The thing I really like about Superpower Beta (which I used and loved on my Cappy), Green Power, and JDU is that they are able to halt that constant struggle when the screen is off (as it is 90% of my time at work). This equates to a much more civilized battery drain. I suppose if I worked in a place where I always had 4 bars this wouldn't even be an issue. Hopefully this explains why I use it. Although JDU probably doesn't do much to "save" battery per say, I think it's invaluable in the way it cuts the communication when the screen is off which in my situation saves battery. I still get phone calls and text messages without issue (depending on where I am in the building). I also have it set to allow data for 5 minutes ever hour which helps.
Wow.. I got a little long winded..

Getting best battery per charge out of your skyrocket.

I am opening this thread to facilitate skyrocket users to share their experiences on getting most out of one charge.
I generally prefer something that shows percentage on top since the battery display does not provide detailed info.
I have tried few free aaps and finally found the best one. It is '2x battery' app. I used to loose 4 - 7% per hour in standby mode. With this app, It gives me 1-2% most in burn in hour. While writing this, I am 36% after 17 hours of regular use.

The only problem with JuiceDefender is that if you use messaging apps like Kik or WhatsApp, it will make it so that you don't receive the messages unless you have your phone active, making your phone pretty much useless.

I dont buy anything til I see proof of screen time and battery use screens.
Just got the phone yesterday, but I must say, coming from the epic 4g touch where I was getting 25 hours with 5 hours screen on time, it doesn't look promising.
But to be fair I haven't underclocked, undervolted and all the other tricks yet. Properly working sleep mode is essential.

I will try the 2x battery,

I use JuiceDefenderPro; custom profile
After 7 hours on battery, I am at 90%.
light calls, 1-bar of signal on 4gLTE, apps grab data every 15 minutes.

Anyone see results w/ underclocking?
I am using Antutu's CPU Master (Free), but my results have been inconclusive (sometimes uses less, sometimes uses more.. can't tell). I am considering getting the paid version of the app (or SetCPU or Android Overclock) to try the screen off profiles.

I use set CPU to underclock when the screen is off and when battery is low. In my experiences the savings are noticeable but not major.
With set CPU, juice defender, and a de-bloated rom I usually go to bed with around 30% battery remaining. That's about on par with my nexus one running cm7.

I haven't really had issues with the battery on my skyrocket. Then again, I'm not I'm an LTE area but you can pretty much expect bad battery life in an LTE area. Regardless, I have noticed something odd about the battery on my skyrocket, and maybe someone can confirm my observations here...my skyrocket tends to lose battery fairly constantly at first up to about the 80% mark then slows down the rate off loss of charge and I notice another huge slow down in drainage at the 30% mark. I've seen this repeatedly no matter what I do. In other words, screen on or off, I tend to see this happen. I'm not complaining as I think a 20 hour battery is great when using it heavily. And I kind of think of the slow drainage at the 30% as a nice perk. I'm running it stock so I can't chock it up to anythnng other than the phone. Any thoughts?

Why does everyone say this about LTE? It is simply not true. All LTE does is give you higher bandwidth with less delay. Wan't good battery life, run a custom ROM. I am running the ICS v4.1 and I must say it is much better than anything else I have tried. I keep 4sq, FB, twitter and gmail all running in the background along with BeWeather updating every hour.

Everyone says that about LTE because (from what I've read) running LTE requires more power due to several reasons. I did a quick search and sprint may be a great indication of proof of the power consumption of "4g" from what I've read their phones disengage wimax when not in use in order to conserve energy. If LTE is faster and operates at higher frequencies (if I'm not mistaken) then it should require more energy. I could go outside the box and come up with some equations that relate frequency to energy (they exist) but I will admit I don't know if they can be applied to the circuitry in phones though I don't see why it wouldn't as the theory is sound. In any case, yes running a custom rom will do wonders for battery but some of us haven't taken that plunge yet. As it is, my stock skyrocket is doing great for me lasting 20 hours. Im out of the house at 6am and usually don't get home till 8 at night. It makes it through that with ease. I'm happy with that. Bring on the LTE, I'll cross that battery consumption bridge when we get there.

"Hypermiler" (Battery Life) Tips

This is a little bit of a boast, I guess you could say... but also educational in a way.
This is my most recent battery life. I found that when I posted my screenshots, people think they are faked in some way. (Posted it here and other GS3 forums) They are not. I am using the stock battery my phone came with. NOT an extended battery. And you can see from the battery graph that the phone was not charged. I guess this is to show that you can use your phone heavily, and still get amazing battery life.
I am using the stock jellybean leak. Not rooted or unlocked.
This is everything I have done to get good battery life.
-I turned the LED touch lights off (I don't like them, they're so bright)
-I have all vibrations off. My phone does not ever vibrate.
-I have power save on.
-I have S-Voice "wake command" off.
-I have motion control disabled.
-I am almost always on wifi (work & home)
-When I am on wifi, I turn mobile data off.
-When I am going to bed, I put my phone in airplane mode.
-I rely heavily on the task manager, I clear my open windows and under the "RAM" tab I clear memory. Probably once an hour.
-I have my sync OFF. I check my email manually.
-Auto brightness.
-I never partially charge. I let my battery go all the way down to 1% then I charge it to 100%. Always.
-Always have a dark background, if possible.
Thats everything. Mind you, I didn't make or receive any phone calls on this cycle. But I did use my phone, as you can see I didn't just let it sit around. Device idle was like 3%?
Anyone else a "hypermiler" like me? I don't get this much screen time every time, it ranges from 5-7. I've gotten more than this and I've gotten less.
Hope this can help even if it's only a little.

-Clearing the ram too much actually drains the battery more because certain apps will have to auto start again every time you clear memory
-Keeping it at around 0-30% all the time should save you more.(I can still see my screen during the day at 30%)
-That doesn't do anything.

-Are there no A/C outlets in your bedroom?
-What the previous guy said, this is a stupid thing to do. Java was designed around efficient use of resources, and restarting running apps (which would happen, unless you have them removed entirely) would use more processing power than you had saved by not having the tasks running in the first place.
-Using Auto is causing the system to periodically poll the light sensor, draining more battery than used otherwise.
-This is how you kill Li-Ion batteries (one way, at least). The whole spiel about discharging fully, THEN charging fully or the battery will have some sort of "memory" of capacity less than actual capacity is how Ni-Cad rechargables work, not Li-Ions. Li-Ion batteries are the opposite. For superior life, keep them topped up as much as possible. FYI
I hope THIS helped, more than a little.

There are plenty of outlets in my room. Lol I just don't need to use them that often as you can see also I hate getting calls and messages in the middle of the night but I use my phone as an alarm sometimes so airplane mode just seems convenient.
This is just what I do. I mean, some of the things I do may not help at all. But this is what I do with Android phones and I've always gotten really good battery life. I've always, always gone down to 1% then charged up to 100% and I've never had a battery go bad on me. Then again I only ever keep a phone for 1 year. I do know that these batteries don't have the memory problem, I just can't bring myself to not fully discharge or charge. I have mild OCD, for real. Little things like that brother me
I'll play with backlighting to see what that does for me.
I've gotta be doing something right. Idk about the task manager, I've just always liked not having programs running if I don't need them to be. I know they arent "running" but it just gives me peace of mind, I guess.
Thanks for the recommendations I will try them.

You getting really good battery life =/= you getting the best battery life possible.
I have pushed ~2 days of battery life without charging many times on my GS3 (with all the bells and whistles running, just mobile data turned off when i'm not commuting), i just don't have a reliable measurement because:
1. I'm flashing mods/roms/kernels/whatever multiple times per week, and
2. I usually charge my phone when it's convenient, which is fairly often.

I stopped flashing because of my OCD. I mean, I'm not crazy but it causes perfection issues and all the ROMs I was flashing had glitches here and there and Idk if you've known anyone with OCD but with the perfection issue, those glitches were all I could think about. So there went flashing. Lol.
Also comes into play with the charging thing. You seem knowledgeable in what you said but even though you said keeping it topped up is best, in my mind, that's destroying my battery. Lol. I really do appreciate your info though.

I'm glad you said it, so that I didn't have to. :silly:
I read your post and the first thing that came to mind was, "there is medication for that, you know.":laugh:

Here's my .02. My battery never lasts that long. Not even close. I'd feel disappointed if it did. I bought my gsiii with the intent of gobbling up unlimited data and using the oc'd processor to run apps till the phone is so hot I have to set it down. I've burned up almost 6gigs of data since the 7th. I get around 4 hours of screen on time most generally. I also throw it on a charger whenever I have the chance. My battery rarely dips below 50%. Like others have said, full discharge cycles are for ni-cad batteries. Li-ion doesn't benefit. Good battery life for me is the lg flip phone we have on a diff line that lasts a couple weeks.

Okay, okay, as long as you admit it... I'll stop being a snarky jerk. I'm totally the same way though. Perfectionist to the core.

It's a very bad idea to let the battery go down to 1% regularly, lithium batteries should be charged more often for better life and more cycles

Sorry but I still just don't believe 7 hours of screen on time. 4 is above average even amazing screen on time for this phone and stock battery. I suppose there is the possibility of using 0 percent brightness, or even lux brightness or something similar to get the brightness even lower.
You said you use auto brightness, I'm sorry I just don't buy it.
People with the extended batteries are getting 7 hours of screen on time not stock batteries.
7 hours of screen on time is literally double almost every other phone on the market with stock batteries. I really fail to see how having minimum usage and a high performing rom will get you double screen on time.
Edit: with that said, in my current situation I will never have wifi access plus I tether a lot so I really have yet to personally see screen on time since I rooted. Before root and stock I got about 3.5 of screen on time.
Not trying to be a douche or anything just very curious about how 7 hours comes about.

you dont get 7 hours because you are not doing what op did for perfection, and you just like other "4 hour" guys in this thread. I can confirm 7 hours usage is totally possible and what left can support one day idle time when you turn off data etc. Iusually dont do that because I like my phone work at full functionality, but I also like tinkering around to keep maximum use of juice, by eliminating wake locks and autostart.
killing background helps sometimes because some stupid apps keeping using cpu after backgrounded. op go and get a iphone, its perfect for OCD since it can get zero unwanted background activity, amazing idle time and stable usage with relatively easier configuration and tweaking.
1% is NO. 1 battery killer, heat is NO. 2, top up at 100% is NO. 3. Li based battery is at best 40%. but plaese its just a phone, charge and use anytime you want. phone outdated way earlier than battery.

While I understand what you're saying I think you misread my post. I was strickly referring to the screen on time which 7 hours of screen on time with stock battery is inconceivable. 4 is about the most you would normally see.
7 hours of USAGE is common.

Well I mean. You don't have to believe me. I mean I have nothing to offer but my word. I do use auto brightness. But because of the suggestion I'll probably set it to manual and see what that does.
I got 7 hours screen on time with the stock battery. The battery says "3.8 v li-ion battery"
I've gotten more than this is the past but I've also gotten less.
Like I said you don't have to believe me but... I'm using the stock battery.
And to the poster who mentioned to get an iPhone - I have one for my business line

battery statistics are poor statistics in general. there are too many variables. luckily we have removeable batteries if we need mroe juice.
heres some postings to add to the mix
put my phone through the paces with fantasy football.
held up pretty well. stock battery mind you. on pace for nearly 8 hrs of on screen time. This isnt with typical use though... With typical use I can get 20hrs and 5-6 hrs of screen time. I thought anywhere from 4-6 hours of on screen time was what people were suppposed to be getting.

Yeah we all use our phone differently. I rarely actually talk on the phone with my GS3 because I use my iPhone for that. But everything else I do on my GS3, reading news, some browsing, xda.
I just thought I'd share what I do for people that may want to get better battery life.

Then I shouldn't use the word "usage". I meant 7 hours screen on time. Sometimes I got 8 or more, but only use it continuously after charging, no idle time.

Yet that involves turning off data. IMO the smartphone should always stay online. In my experience, iPhone can get constant -4 ~ -5ma juice flow during idle even with data (2G) and all the push notifications on, which are the only things I want for stay online. I feel its hard to get similar result on my GS3 though.

I'm always online, whether it's wi-fi or 4G. Luckily I have wi-fi at home and at work.
Like, literally as I'm walking out the door of my house, I turn on my mobile data, and when I get to work I turn it off. When I'm leaving work I turn mobile data back on and when I get home I turn it off.

what you did is pointless. If you leave data on, data is not connected when wifi is connected, and it will connect automatically when no wifi connection.

It's not pointless to me. As I said a few posts before... I have OCD, obsessive compulsive disorder. Things like this affect me. I know that being connected to Wi-Fi that data is not connected, but in my brain, it's as if something is telling me that because my data toggle is on, it's running.
I really can't help it.
