Battery life.

I havehorrible batter life and it takes forever for this phone to charge and it overheats. I'm using the andromeda kernal and OC widget. Can someone tell me some settings I should use? Or tweaks or whatever? I'm talking non-commonsense stuff (not stuff like "turn 4g off")

Turn on Airplane mode and leave it on. Tell people to call you on the house phone. Your battery life will improve dramatically.

The radio really sucks up tht much power, huh? :/ I wish sprint used simcards so I can have a reason to lug around my hero for when I'm out for more than 3 hours

Wow, 3 hours huh? I'm at least getting 8. I was getting 15 or 20 hours, but then started putting lots of widgets on my screens and that really killlllllllllled it

I usemy phone a lot. I was spoiled by my hero. I was getting days on a single charge with the same usage, if not, more. I wish I knew what's killing it so fast :/ spare prts says the screen is a majority of power consumption, but I usually have brightness on 0 (its plenty bright enough. It seems brighter than my hero at 50% ).

{Battery Issues} Phones mysteriously cuts off and loses charge

one min my evo is on and battery might say it's at 49% charged. then out of no where, my phone will cut off and when i turn it back on, sometimes its completely dead. sometimes, it's showing 2-4% battery life left.
WTF is going on?

Is it a stock battery from sprint/htc or one you got from eBay or any other seller?

it's the stock battery 'the red one', shipped with the phone. it use to work fine up until a few days ago, when i noticed what was happening.

Ive been purchasing 2000mha batteries from eBay and they have been working great for some time now.
I believe that sometimes the length of your battery life experience will depend on the way you charge it through out your day and the amount of charging cycles you've used during the life time of that battery.
Sure I do agree that certain things can be done to improve battery life, but sometimes... It's just time to discarded it and get a new one, imo anyways.

I figured that, but I didn't wanna get a new battery if it was a bad ROM flash or something.. but I'll use my extended battery when I get home and see how it plays out. I just that damn bulky Ness to that battery.

Change roms and wipe battery stats in recovery. If its still acting funky then it must be your battery. I think sprint replaces them for free if you tell them that your battery is disfunctional

I had same problem when I bought my 3500mah sedio battery. So I exchanged it. Most likely there is a problem with your battery.

Yeah, just did that. Think it was over used. Regular charge, trickle charge, over charged. It's toast.

Been running the new battery over a day now. No restarts at all. Guess it was the battery.

Battery Drains QUICKLY!

I got school at around 6 am. By the time I eat lunch it's already at 57%. By the time I get home around 5 and it's already at 17%.
All I do is listen to music (doubletwist/playerpro) and play Cut the Rope, WTF!?
Cell standy by is 46% in batter usage followed by wifi with 11%
any help guys?

What I tend to do is have brightness down to about half. Have you also tried fully charging the phone, taking the battery out and charging back to full? I sometimes find it drops down but regenerates itself.

Brightness is below half,I never go over. WiFi is on but not all the time.
Stock rom 2.3.4 rooted

Do you have data off?

How's your phone signal most of the time? It has been proven that low/bad signal drains battery quicker than good signal.
Sometimes certain buildings/rooms have pretty bad reception making it a huge drain for your phone.

This is a useful piece of information, however is not really practical. Ideally we don't want to be turning off our phones on every charge :/
I myself own 3 batteries, and alternate them (I have a wall charger for the batteries)

what ver are you using if 2.3.4 the battery issue is fix.

I get 3 /4 bars, at school right new and yea some times I get nothing, especial ly during the subway ruse which is an hour

Once I updated my phone to 2.3.3 I noticed that the battery life was sub-par, only lasting 3/5s of the day on a full charge.
I proceeded to root my phone (as I don't have the money to unlock my Big Red Bootloader); after installing SetCPU I took down the clocking meter 1 notch (768MHz) and the phone is stable with not difference in performance (so far). Doing this and removing some unneeded bloatware has increased my battery life 2.5x and I can go almost 3 days on a single charge.

xiEvo is correct and I've read a lot of good stuff regarding battery life with 2.3.4. I can only begin to imagine what kind of battery life I'll have once I get that update.

get juice defender off the market ultimate version is best. this will lookafter everything for you.. juice defender is a must have app for all android devices

I'm 2.3.4.
Honestly I had the best battery life with 2.3.2, IDK why.

Battery question

This has probably been asked a million times but I have searched for an hour and cant seem to find exactly what I am looking for. I reset my battery stats because my battery life has been horrible the last week. My phone now says fully charged but the meter only shows 92. Should I let it die completely and recharge completely and then it will be fixed or will it just do the same thing? I am on ICS passion 10.6 if that makes a differnece. Ill be getting a slim 220o mah battery next week but this is still annoying me. I work 10+ hours a day and text my wife a lot and im only getting 13 hrs on the battery. About 100 texts, 30 min of web and I get auto updates via craigslist notification. GPS and wi-fi are off and my sync settings are for 1 time per day. Thanks all!

13 hours is pretty good. also, read this: https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT

I like to use an app called android booster u can go in and see exactly what app is draining the most battery that might help

Did you check out the stickied guide called "[How to] You Want Better Battery Life:::Read This" in the Vibrant Q&A section? There's some really good stuff in there. It won't help in solving your battery only charging to 92% issue, but it should help you get the most out of your battery.

Thanks all, my biggest issue I'd with the meter reading wrong, but I'll check out the better battery life thread, I can always use an improvement!

Try downloading "Battery Calibration" from the Market. When your battery reaches the max charge that you see possible, calibrate it, and reset your phone. Always works for me.

Battery works fine?
So no problems with this battery? I saw an 1800 but this might be better if it works and fits ok.

I should have it tomorrow or wed ill let you know about the fit

In the picture on the link you provided, that battery looks like it has four contacts, not like the Vibrant's three.
Some other pics I found on google images show that might be the case, too.
I am not holding out much hope that this battery will work for you. But if it does, please follow up and let us know.

^^ This will solve your battery problem.. The 1800 mAh adds an extra 25% battery life span.. 25% make a HUGE difference

Did it work?? I need to get the 1800 milli-Amp battery. Right now I'm doing the 2 battery swap deal, which isn't too bad

thanks, i'll wait for your updates to see how this battery holds up

Someone help me! (BatLife woes)

Alright I wasn't going to make a thread on this because this topic is already discussed elsewhere naturally but I feel my situation is different. All over the place I see people reporting great battery life with ICS.. well mine is HORRIBLE. I just flashed the latest nightly for Pete's bugless. I didn't change the kernel. Everything is stock. Only a few apps installed. Noop for scheduler and ondemand for governer.
The phones been off the charger for 55 minutes and I'm sitting at 76%. Idk what's going on. I've tried so many rom/kernel combos and I seem to get the same exact battery life no matter what. Around 6-9 hours with less than 1 hour of screen on time.
Things I've tried to combat this:
Undervolting
Freezing apps
Restricting background data
Underclocking
Brightness set to auto
And I'm sure a few other things I'm forgetting about. I've done all this and still get ****ty battery life. I've flashed the new radio hoping that it would solve my issues but no dice. My signal strength reports at -67 dbm yet the bars never go over 2. 3g or 4g. Even after updating plr.
On gingerbread cm7 I ran brightness at 70%, ocd to 1.4ghz and always got 15+ hours.
For the love of god someone help me. Cuz I think my phone hates the cream sammiches.

try this kernel, trinity teuv underclocked/undervolted kernel, oc'd gpu http://goo.gl/rY6ga
and do not set brightness to auto, its a battery killer. i keep my brightness at about 20-25%.
also, be sure to fully discharge your battery then charge it completely, after 2 or 3 cycles you should be good.

I do this every day lol I let the battery drain to around 15-30% before I plug it back in.
Screenie: 1 hour later and I lost another 25% this can't be rom or kernel related. As I have tried trinity already and the same thing happens

Ugh. Another 20% gone. Its only been a half hour from the above screenie. You guys see my dilemma? Lol **** me.

i was having horrible battery drain after flashing a new rom & kernel - i finally figured it out that my APN settings were messed up and I re-entered them according to the correct carrier settings.
i don't know if that will apply to you since it looks like your 4G data is working properly, but since I was on wifi 99% of the time, as soon as I went off, my data didn't work. but it's something to look at.

4 hours later I'm down to 4% from a full charge.

Could you try better battery stats to see if something is holding a wakelock?

I would be interested to see what your battle life diff is without 4g switched on. Also in that 4 hrs what was ur screen on time?
Have you thought of trying a new batt? Just got an OEM Samsung for 5 bucks on eBay. Worth a shot.
Oh remove fb app it blows...install friend caster way better less batt make sure you change the sync interval.
You could also try green power from the market to manage your data use while screen is off.

Ok here's how my battery performs back in cm7 nightly 174 gingerbread. Almost 4 hours and only 25% chipped away. If you look above you'll notice I lost more than 40% in the same time with ics. And I'm doing nothing different. I'm even overclocked to 1.3ghz ondemand with noop for a scheduler.
I think I'm sticking to gbread until official source is out. Maybe then ill get the same battery life.
Sent from my Nexus S 4G using xda premium

That is really weird, if you have time try Milestone 3 and SG's latest kernel and just leave the settings stock . I get wonderful battery life with it hopefully you do to
Oh and are there any apps you are using on ICS that you aren't on CM7?
Sent from my Nexus S 4G using XDA App

Nope. Lately its only been a handful. I actually have more apps installed on gbread to achieve some of the features that are baked into ics. I just don't get it. Ics hates my phone. I even used the GPS today. So weird.

This. If you are installing the same ol battery-draining POS app then you are not going to fix it with any rom or kernel.

So you guys think my batter watcher widget is preventing my phone from sleeping properly? Ok.. I'm on cm7 right now. Battery is def back to normal. And this is with bacround data on. Ill delete bw and get better battery stats.

Better battery stats is not the same thing as other (mostly useless) monitoring apps.

Look. 16 hours on gb. If none of my apps are killing the battery then what could it be?
