[Q] Questions about improved battery life

So the day I bought my vibrant I had data issues. I talked a tmobile tech support guy and he helped me with my problem, great. But afterwards he asked me how I was liking my phone since he had one as well. We talked some about the phone and all, but then I asked about the battery life.
Heres the interesting part, he said after getting around 5 hours of use out of a full charge, he put the battery in the freezer over night (in a zip lock) and charge it afterwards. He claims to be getting a whole 24 his of battery with moderate use.
Is there any truth to this statement? I'm sure he was over exaggerating to some extant but he was a tech and I wanna take his word for it but dont want to try it lol.
Another thing is I want to know other ways to improve my battery life. I heard "training a battery" thrown around these forums, how do I do this?
I try to keep stupid services from running by going to settings>app>running services. Is this enough or is there a better way?
First post, hope it was a good one lol.

I hear ya man the battery is really bothering me too. It's basically dead by the time u get home, which is not good enough for me. I called T-Mobile and they are sending me another battery.
When I get the new battery I'll try the freezer thing.
Well, gotta go... battery is almost dead at this point. : (

when i got the phone i calibrated the battery like i did with my g1 with the cm releases. basically let the battery die completely then charge fully. don't know if that had any effect, but with how much i use my phone (moderate-light texting, browsing, gps when it works, no gaming) i could probably get through 2 full days. with playing some games i can still easily get a full day.
putting the battery in the freezer overnight shouldn't have any long term effect on the battery. it may improve your battery life very shortly because a colder battery holds it's charge better, but once it's heated up (or at regular idle temp in your phone) any small benefit you may have had is gone.

Try Juice Defender. It is working wonders for me. I am going on 8 hours of up time and I am at 75%. Normally I would be getting close to needing a charge.

What settings do you use? Do you use the default settings from the setup?

What the heck are you guys doing to kill your batteries?
I use my phone off/on all day off the charger at 6am and I turn it off and charge it at 11pm. Often I'm normally around 30-60% depending on the use through out the day.
Turn off what you don't need. I mean do you need wifi on all day? Do you need 3G on all day? I'm guessing you don't unless you are streaming video all day.

Yeah I don't get it, this phone has great battery life for me. I get about 20 hours out of a charge and I use it quite a bit.

Can you elaborate on your settings? I was thinking of installing this app and getting rid of the task killer since I'm getting very inconsistent battery usage each time after a full charge. Have you tried Ultimate Juice?

get rid of your task killer.

I think its just luck of the draw. When i first got my Vibrant i was getting at least 20 hours out of a charge. I had to exchange my phone due to a few annoying dead pixels and now im lucky to get 8 - 10 hours out of a charge. Everything is set up as it was on my original phone.

I just use the default settings at startup.

I have all widgets turned off, wifi off, gps off, brightness on minimum and a solid/static black wallpaper.
I use the phone for very few calls and very few txts... mostly use it for web browsing throught the day and some news apps - with a little paper toss mixed in.
I use my phone more than the average guy, but the usage is in line with my usage on my iphone and HD2. I know how to be gentle on the battery, but I still have to charge it when I get home from work.

My battery lasted 2 days the other day. Got down to 15 percent. It's very strange. I was using it but not very often maybe once every few hours. But I played some ff7 to demo to my friends, used the gps to get directions. Most importantly I started killing all nonessential apps with astro immediately after I stopped using them. I think this is what's prolonging my battery. Sure theyre not using anymore cpu cycles but they're still taking up ram, and that is a constant drain folks.

There is no difference in draw whether you are using 1K or 256 MB, the chip will always draw the same amount of power to maintain the memory.

I measured current consumption from the battery. It takes about 20 to 60 seconds for the CPU and everything to ramp down into their sleep state. Anything that wakes it up often kills batteries quick. I believe most of the power being used is idly switching sleep states. Can't wait for custom ROMs to allow tuning.

The longest anyone has had it on their phones is like 15 hours. Give it a few days.

I fixed my gps early this morning and then set it up with a full charge to do a battery calibration. I turned 4G on to help it drain. I also used it to read xda for about 30 minutes earlier this morning (not sure why the battery stats don't seem to show everything that has been running). Here's where I'm at 8 hours later. I would say the battery life is pretty freaking great! Can't wait for some UV'ing once we get source.
Note: I have Overclock widget set to 1000/200 screen on and 400/200 screen off.

i somewhat second this i have left it unplugged all last night and i am at like 80-90 percent full with some what use..

I am still using juice defender, but my phone as been off the charger for almost 12 hours and I am probably around 75% battery left. I will be testing out turning off JuiceDefender tomorrow, but for now it looks amazing.

it some actually deads faster than 2.1

I've been having pretty fantastic battery life. So far the phone has been unplugged for 6 hours, I've been texting on and off all day, and played angry birds for about an hour. I'm sitting at 75%. Probably not fantastic but not bad.

I've noticed an improvement, but as to how much, I'm not sure. Maybe 20 to 40 percent better.

excellent battery life
61 percent with some youtube , texting surfing the web angry birds and 4g on(sleep mode for 4g works really well) and apperently my gps was on all day. Its been 7 hours and 32 minutes ..I would normally be at like 35 percent

I have definitely noticed an improvement. It seems as good as baked ultimate and that says a lot.

I am getting battery life like it's a completely different phone.
I was always rooted but with stock roms and kernels and on 2.1 my battery life was frighteningly bad. I have been on for well over 8 hours and using my phone off and on all day checking out froyo features and the battery indicator is showing still nearly full battery life. On 2.1 I would have had to pop it on the charger at around 2 pm today or earlier.
* I am going to be making a thread about LEGIT improvements that froyo gives us with this phone. There are a ton of piss and moan threads, but froyo adds a ton of features (several i'm sure I don't know about) and MUCH BETTER battery life. *

[Q] Absolute Best battery?

What rom (stock sense look) has the best battery overall. I rooted my moms evo to get her a great battery life but it still seems to be dying really quickly. I am using 4.3.1 kernel. She's only getting around 6-10 hours of battery before she has to charge it. I had the evo before and could get a full day and a half before charging it. I can't remember my setup since I switched to the evo shift. Any suggestions would be greatly appreciated, thanks.

im using the cm7 rc 2 whatever kernal is package there is PHENOMINAL im at 60% @ about 12hr..... Moderate use between wifi and 3g

That's the best you're gonna get with NORMAL usage and a REGULAR battery. All those users that say they get like a day or two are full of it. They get that long because their phones are sleeping most the time. I've used EVERY rom/kernel combo out there and the best I ever got was about 15 hours. I literally use my phone all day while at work from browsing, texting, calls, facebook ,twitter, and games. There should be a definition for moderate. I consider myself a heavy user; unplug at 7am and my phone last until about 6pm with about 20% left. Its not going get any better than that for a moderate to heavy user. From sense to aosp with the stock battery I just never achieved better results but I'm pretty happy since I get to work at 8am and get off at 5, buy 7pm its nearly dead and I just plug it up. You should invest in an extended battery imo.

I agree to a point. I mean, it all depends on usage. I can believe someone with light-moderate use can easily get a full day with the right setup. I do it now with CM/Savage, but I'm definitely not a heavy user.
I do see some people make wild claims of 2-4 days without a charge.. and I think it's possible IF you don't use your phone or you turn everything that makes it a smartphone off. Which is pointless IMO.
Nobody can really give you the perfect setup because every EVO seems to behave differently. We can only make suggestions. Make sure your mom s awareof all the things that can drain battery (push notification, updating widgets, weather updates etc etc). I would then research a good sense rom/kernel because CM7 is a definite WIP with different issues for different users, it may turn her off.
Maybe check out MikFroyo or Myns rom. I hear a lot about how good they are.

+1, its just crazy I see people throwing crazy hours out there lol. I think if your phone is sleeping 75% if the time then you shouldn't even talk about your results since that doesn't fit into the norm for usage. Most people check their phone like every 10 mins(don't quote me) I know I do lol. People throw around like 36 hours and even longer its insane to me.

Sent from my PC36100 using XDA Premium App

I don't know about not being able to get more than a day of battery life and use your phone. Using MIUI with a Savaged-Zen kernel I was able to go almost 2 days without even plugging it in once (I'm specifying this, because I've seen screenshots where people claim crazy battery life, but the graph clearly shows that the phone was plugged in and charging several times throughout that time period), and my display usage was still 44% of my battery. That was still minimal usage for me. I posted the screenshot in the MIUI thread if you care enough to check.
I do mostly agree, though. Most people posting outrageous battery life have display percentages around 5-10%, clearly never removing the phone from their pockets.
Anyway, as for the OP, the biggest missing variable is that we don't know at what percent your mom considers it necessary to charge her phone. If she plugs it in around 50% to be sure she can make it through the day, that means she could have gotten another 5-8 hours of battery life (assuming she's not draining it down to 0%). This fact could make the difference between bad battery life and a paranoid mother.

Try the ava froyo z3 I love it best rom I've used so far so guess I'm sticking with it o and get her juice defender with ultimate juice and lock it down so it kills anything she's not using

I agree with most of you people. Initially went to FreshEvo by Flipz when I rooted and battery life did not change much from when I was running stock. I have since switched to CM7 and battery life is significantly improved. Now getting 12 hours on a single charge with moderate use. I always turn 4G and wifi antenna off when not performing any data-intensive use. But I refuse to kill my 3G data connection when my phone is in my bag or desk while at work. Reality is that it IS a smart phone and killing the data to save battery life defeats the smart phone bit, no email no Facebook syncing no MMS etc. The only time I kill 3G is when I am in the mountains skiing.
My problem is that I work a 12 hour shift so 12 hours of bat life is not ideal. I have invested in an extra charger but would obviously be happy to not use this. I have heard lots of testimony that the savaged Zen kernals show some promise in improving bat life. When CM7 final drops I plan on flashing one of these kernals with the new ROM on wipe. I will stay away from the SBC version though for fear of improving battery charging but having my phone melt down or pop on the night stand next to me while I sleep... or worse in my pocket!
I will report back if I get any significant results.

+ 1 the battery needs a few cycles to break in. Also, are you rooted are you running a custom room or kernel these things can have an affect on your battery also.

a day and a half?? howd you pull that off? im usually charging about 10-14 hours thorough heavy use.

agree with everyone else, give it a few days.
I used some advice i found the said kill battery, charge full, kill battery, charge full, kill, charge, then use it. Charge it while it is off during that time.
First couple of charges, the battery would die after about 5-6 hours of constant "messing around" with the phone. Now it seems like it'll last a good time.
Im completely stock as well.

Like everyone else said you really need to give it some time to break in.
My first day with the Nexus the battery was dying as I left work (roughly 9 hours off the charger).
After owning the phone for about a month now it's changed dramatically.
It lasts well through the entire day, every day. Before I go to bed it's usually sitting around...
70-80% LIGHT use.
50% Moderate use
35-40% Heavy use. (Note: I don't play games, Heavy use to me is multiple short calls, many emails, many texts, IM)
I've never actually had the phone die on me.
I'm using CM7 (Latest Nightly) and the Netarchy CFS Kernel (default settings with the exception of VooDoo Color tweaks)
I don't use Juice Defender. Phone sits on 3G most of the day at the office, at home it sits on WiFi with the WiFi sleep policy set to never. (Wifi uses much less power then 3G, if you have WiFi, USE IT! and set sleep policy to never so WiFi stays on constantly instead of switching back to 3G when the phone is idle)
Do use a task manager but it didn't seem to make a huge difference.

Aside from letting your battery calibrate, you should try out juice defender. I know alot of people might scoff at a such an application but I've experienced over a two fold increase in battery life using said application. However I am running an undervolted netarchy 1.3.4 kernel with Oxygen, but said increase in battery life is with the same configuration.

Yeah it takes around a week to break in the battery. My battery life is pretty awesome. I usually charge it every other day now. It lasts a long time.
Sent from my Nexus S 4G using XDA App

Guys... battery break in isn't gonna change his usage from 4 hrs to 12 hrs. No battery break-in does that.
In all these cases I suggest looking at battery info in the OS itself to see if something kept the phone awake or whatever.
Sure heavy use in your first few days will always take a huge toll on battery. Calibration shouldn't totally throw off your battery life down to 4 hours either.

You guys who say heavy use, can you quantify that?
talk time per day?
texts per day?
roaming?
4g?
how many emails sent/received per day?
time on internet?

/shameless plug
try battery tweak in dev forums... i posted it in both of them

I'm in the same boat as you. Just got my Nexus S 4G on three days ago and the battery dies QUICKLY. The first day it died in 5 hours (with normal use and 4G off). By the time I unplug it and get to work, which is only a 20 minute drive, it's already down to 93%. I'm hoping everyone else is right in saying that the battery just has to be worked in a little.

I have 8 hours on battery right now with about 40% remaining in day 2 of my Nexus' usage. I made about 6 phone calls, sent out about 20 text messages, browsed the internet while waiting for a job interview and played Plants V Zombies when I was taking a dump.
I really only expect it to improve from here.

Out of curiousity, does anyone here have their "Use Wireless Networks" checked under the "Location and Security" settings (where it uses your 3G)? I have this enabled and I know this will drain my battery, but I wonder how much? The only app I have that updates my location while the screen is off is the stock News and Weather app (which only updates every 6 hours, a bug that automatically turns itself back on if you reset your phone). How much collection would Google do other than that?
Also, the other thing I have enabled is my Exchange set to push through the default Email app. However, this never really shows up on the battery usage app, so is push STILL killing the battery a lot through the stock app?
I'm just trying to see how people can get two days with 50% left after work (if just on 3G). On WIFI, MAYBE, but def not on 3G......

Is my Nexus 10 faulty?

I've had it for around a week now but I've yet to get over 6hrs battery life. I keep the display on the dimmest setting, have no bluetooth or anything on apart from wifi. I keep location services and Google Now off and I use it mainly for Internet browsing, you tube and a couple of bejewelled type games for around 10 mins a day. I haven't watched any films on it or played any real heavy duty cpu smashing games at all.
No matter what I do, I just don't get any more than 6hrs before I get the 15% battery warning.
I don't appear to have any wake locks, the battery graph shows that when the display is off, the tablet never seems to be awake.
I installed Better Battery Stats but I don't really understand what to look for.
Can anyone suggest anything before I give Google a call and they tell me factory reset and try again?
Any help would be greatly appreciated!

Mind posting a picture of your betterbattery with:
-Partial wake locks since boot
-Other since boot
If you use it like you explained you should be getting more than 6 hours.
I'm using a custom rom and kernel so that might explain why I can idle for an entire day and only lose around 6-8% depending on how many emails I get.
Typically I get around 8 hours of use which includes watching movies over stream, YouTube, flip board, email, xda surfing, and a few other things.

Thanks for the reply, I hope this is what you wanted - I'm not sure exactly how to do add files to posts but here goes..

Anyone please?

Charge your device to 100% and use your device the way you typically have been. Once you get down to red numbers, post a screen shot of the regular Android system battery usage. That might give a better picture of what's going on.
You can also charge to 100% and disconnect from the charger and let your device idle. Better battery stats is a better tool to use when you aren't using your tablet, and you are experiencing battery drain.
Also, you didn't mention whether you are stock, rooted, or rooted and ROM'ed. Please do that and we can go from there.

I've had it for around a week now but I've yet to get over 6hrs battery life. I keep the display on the dimmest setting, have no bluetooth or anything on apart from wifi. I keep location services and Google Now off and I use it mainly for Internet browsing, you tube and a couple of bejewelled type games for around 10 mins a day. I haven't watched any films on it or played any real heavy duty cpu smashing games at all.

Screen time. I thought that was kinda low after seeing loads of people get 8 - 9 hrs and some get even more!

You said 6 hours battery life in OP, implying you were getting that battery life for the device... ._.
Congrats. You have a normal device... People may be using screen filter to get those results, but why not just enjoy the screen instead of gimping it for an extra hour or two of dimly viewed screen...It's not too tough to charge it overnight.

And if its really that big an issue, go get KTManta, Franco, or any kernel that lets you reduce the maximum clock from 1.7 to 1.3 or 1.2 GHz. I have benchmarks for the Manta at frequencies ranging from 1.2 to 2.1GHz and there's not a big difference in performance.
