[Q] need help wuth a bad battery life and new keyboard - TouchPad General

My battery life used to be better but my touch pad has gotten its fair use.
I would like to be able to survive the day on a charge if possible with moderate use. I'm on fat and creamy with juice defender and that has helped loads but I was wondering if anyone else has some good battery saving tips or maybe a from with even better battery life.
Also my touch screen seems less sensitive than when I got the tablet (okay so maybe my tablet is more than just moderately used), and I was wondering if anyone has a keyboard with buttons easier to tap than the stock.

Some use Juice Defender to save battery. You can achieve many of the same savings by setting up profiles. One sure way to improve battery life is to use RootDim (free app) to lower screen light level (the TP screen is very good so lowering level below 25 % saves battery and still looks good.
You may to consider RandomROM's Falcon ROM... gets great battery life.

Which OS has best battery life !

SOMEONE !! HELP !!
I need to find out which ROM has the best battery life, can someone point me in the right direction pls....
Thanks

Try them all. It all depends on how you use your phone. There's no magical rom with great battery life.
If you use your phone a lot, go for a ROM which isn't overclocked.
If you want the longest idle time before recharge, I think you should set the "conservative" governor as a screen off policy and you will be fine. Of course you can also disable features such as data but you will loose many useful features of your phone. Unlike what some people says, disabling GPS doesn't improve battery life as it isn't used except when you start an application which use it.
Battery life is most affected by the screen light.
And with every rom you have to callibrate your battery. Most people with poor battery life haven't done this.
The Froyo roms are the best options because the are faster and less stressing for the juice.

They all have the same battery life (give or take 5 minutes)
All pretty similar.
Use an underclocked kernel, play around with brightness settings or use an app such as ultimate juice / juice defender to regulate 3g / wifi usage

How to callibrate my battery??
My Hero just lasts two Days with 691mhz Flykernel 11 and Elelinux 2.1 and no 3g.
I just hear a lot of music with it, connect it a few to wifi and play some games in the school.....
How long does your batteriest last?

You say two days without a charge with occasional wifi use (wifi on, screen on, phone signal on), and games playing (sound on screen on, processor busy) like it's a bad thing...
Since the mid 2000s phone capabilities have been surpassing battery performance at a remarkable rate. With the advent of the iphone and the gaining popularity android smartphones, phone feature demands have exploded while battery technology just isn't anywhere near providing the kind of battery life we expected on our dumb phones, ie, don't bother packing a charger for a two week holiday if you charge up before you leave.
This is a large reason why new technology is being created with more efficient manufacturing processes, smaller dies, etc etc, as it is easier to reduce power consumption at this time than it is to build slim, cheap, high capacity batteries.

Mine struggles to get a day battery life, with not very heavy useage... how do i calibrate my battery?

Battery use

Even running PW edo5, screen set low, and all other battery saving tips, my display still uses over 80%. Was wondering if anyone had any advice.
Sent from my SCH-I500 using XDA App
Use the phone less... jk.
I use two utilities to save battery:
Screebl Lite will use your accelerometer to automatically keep the screen on if it is being used or turn it off if not (if the phone is flat it lets the screen turn off.) It can be useful so you don't have to turn the screen on and off a lot.
Screen Filter puts a dark filter over the whole screen, to allow the phone to go way under the default brightness setting. It isn't really practical during the day but it saves a lot of battery if you can set it even at 50% and lower at night, in bed, etc..
and make sure that you aren't leaving wifi and data on when they aren't being used, same for bluetooth, gps, etc. to save battery overall.
It stands to reason that your display will use the most energy. All that 80% is telling you is that while your phone is running it is using a certain amount of power, of that certain amount your display is using 80% of it. I don't think it will ever use much less than that no matter what you do. After all when you are using your phone that is the one thing that is always active.
Why not just keep spare batteries around? The last time I ordered batteries I paid $2 each for Samsung batteries out of China. They are the ones for the Epic maybe, but the same thing other than color. Requires a custom kernel (pretty much any kernel now other than stock) to charge them in the phone. However I almost always use external chargers as I always switch dead batteries out.
Everyone worries about battery life, its a smart phone if you use it it eats batteries. All you can do is make it slightly better than it was. Or you can just keep a spare battery in your pocket just in case and use wifi, GPS, 3g, and still have a bright screen. I have 5 batteries and 2 desk chargers on my desk (2 fascinates in my house).
I believe in the Glitch V12 kernel, you can have custom display dimming settings. I'm not sure if this a completely objective observation, but it seems like I could get the dim brightness setting darker on this kernel than in the stock.
Well thanks for advice I will def give those 2 apps a look! And yes, I do use 2 batteries. The stock 1500 annd also an extended 2200 I found on Amazon. Great investment even though it does add some bulk. I use a battery calibration App with them. Just wonder if that App is enough or should I be doing some other type of calibration?
Sent from my SCH-I500 using XDA App
Should be fine, just make sure to be at 100% charge on the battery for best results.
Also let it be known that on miui with glitch my display uses 6% of my battery.
Sent from my MIUI SCH-i500
6% ????? On the DISPLAY? ??....WOW that's THE lowest I've ever seen! How is that possible?
Sent from my SCH-I500 using XDA App
6% is easily possible if you never use the phone all day. The system will hog all of the battery with the screen off. I think the most important thing is how many %/hour you lose when you are not using the phone. I think about 2.5 to 3% per hour is pretty typical for me.

[Q] System Power Saving

Anyone use this (or the custom ones) built into the Note?
Are they effective or is Juice Defender a better choice?
Regards,
Stu.
i rooted mine and dropped the clock a little under 1ghz using set cpu and i get two days of light use. a day and a half heavy use. i didnt notice a performance difference either.
Just Rooted mine and have seen battery life definitely decrease.
I am going to drop the clock and hopefully get a little better battery life.....

best app to extend battery?

There is much discussion on mastering your battery life in other sections, but concentraining on the app part alone, I would say Juice Defender has made a huge difference for me. I can get over 24 hours unplugged with about 3-5 hours of screen on time. The free Juice Defender helped a bit, but it wasn''t until I bought Juice Defender Ultimate that I saw large gains in life. I basically run my phone set up so that it kills all data connections and checks periodically (5 minute intervals) for notifications. Also, I have it set to learn so that when it knows I'm in an aread (based on tower ID, not GPS) that I do not use Wife, it will not bother looking for it. There are a ton of little settings that you can tweak to find just the right balance of saving verse use.
I've heard good things about Juice Defender as well.

I agree with both above about Juice Defender. I've had JD since my Vibrant days and found it to be very useful. May I also suggest a "all black" wallpaper and lowering your brightness to its lowest, this has also help me tons.
GL to you!
I too rep juice Defender like a champ. however............
if your getting only 4 hours battery lift, then their is probably a more serious issues. Im not sure wakelocks alone could even account for such poor battery longevity.
I would also recommend CPUspy from the market. This is a helpful tool to make sure your phone is going into deep sleep mode.

The key question is 4 hours of what? If I sat and played games for 4 hours, my phone would be dead or close to it depending on the game.
Lol. Not even! Modern combat can drain 10% of my batt in 20 mins

you need to install BetterBatteryStats to find out what's eating your battery. I use to use JuiceDefender & my biggest complaint was it was having a hard time reconnecting to wifi once the screen was on. I got fed up & went to GreenPower which has more options, IMHO.
I can get 15-16 hours of run time with 4 hours of screen time with the following. No Juice Defender.
Wifi off. Data and BT on. Screen Filter set to 75% most of the time, and 30% in pitch black. Screen Filter is a biggie - even Juice Defender can't cut the power useage of the single biggest drain on this phone... the screen.
Pls say where I can find screen filter setting. Thnx
Sent from my SAMSUNG-SGH-I717 using Tapatalk
Turning off auto brightness, and turning off screen auto rotate (and enabling it only when needed) help quite a lot!
Screen Filter is an application. Its primary use is to dim your screen far lower than the stock "low" setting. In many people's opinion the low setting is still way too bright in a dark room - Screen Filter lets you go as dim as you want, although too low and it makes everything look gray which is why I stick to 30%.
I noticed that it works along with the built-in auto brightness setting, and the app will allow you to dim the screen only a little if you want, so I started using it all the time on a 75% setting. The screen will still brigten and dim based on ambient light, but it will just be a little dimmer than stock. I've found a 75% setting along with auto brightness works well in all situations except full sun or a dark room, so I have two Widgets on my home screen - one for 75% (most of the time), one for 30% (for a dark room), and I'll turn it off for full sun. A lot less fiddling around than turning auto brightness off and manually adjusting the brightness all the time.
Since LED screens use less energy the darker they are, this effectively extends your battery run-time.

Awful Battery Life

My battery life is ridiculous. It doesn't use that much when the screens off but when it's on it uses 10% in about 15-20 minutes. I'm on a sense 4 rom and on senseless it's not much better. Even if I'm streaming music with the screen off, it's okay. It seems the screen is using a massive amount. Is there anything I can do? Thanks

Nope. Thats typical.
You'll get around 4 hours or so of continuous screen-on time, and thats IF you start with a full battery...

i get 2 hrs screen on. less if im playing games, currently im obsessed with dead trigger. ive been playing with my phone plugged in....
You can try slim rom. It worked a little for me. I have the same issue you're describing. Tho for me I also get drain while the screen is off as well due to being in a poor reception area most of the day. Also make sure ur brightness is no higher than 30%. Its just the phone man. The screen is a hog. Honestly I've Bern wondering if there's a way to turn off every other pixel on a hardware level or something cause frankly its ridic.

Yep, the screen's the culprit, and it's pretty bad. Try JuiceDefender. If you get one of the advanced versions you can really conserve battery power while the phone's not in use, which will extend the power available for screen-on use. Also, you can reduce the CPU speeds a bit, which will also reduce draw and lower the heat.
I use JD Ultimate. My idle/standby time is now very nice, but as others have said there's only about 4 hours of use with the screen on.
I keep hoping the reason for the ICS release delay is because they're working on battery life issues. :sigh:
Thanks guys. I guess it just isn't great on battery life. I've tried juice defender and stuff like that but i was never a fan. I'll give it another try. It sucks to have 50% and the next time I look it's at 40... Haha. Is auto brightness better that doing it yourself?
Turn off any auto syncing and location services if they're not needed.

I wouldn't bother, JD has never worked well at all in the Rezound.
I have one of the paid for advanced versions of JD and I don even bother installing it anymore. I think my battery life was actually worse when running that.
My solution now is to use a mugen 4000 battery. That battery lasts so long I don't even bother to set a screen timeout anymore.

Do any of those battery saving apps work?
I'm not crazy about big batteries. How is their 1900 one?
I've got about 15 hours once off newts sense 4 rom but with like 2 hours screen time. Screen time is really all that matters in deciding if ur battery lasts 5 hours or 15, unless u have things like music going on while the screen is off, but 2 hours or so is about all the screen time I can get
about 4 hours screen on with standard and 6 hours with ext battery
Same here, I've gotten up to 14-15 hours on a single charge, but with twoish hours of screen time. Other than the screen being a battery murderer on this phone, I've noticed that having poor reception really wreaks havoc on the battery also. I live in the sticks of PA where I'm in a crossover area, and continually switch between 2-4 bars signal of 1x, 3G, and 4G. And if I don't have a stable signal for a while, the phone will actually heat up and start discharging the battery due to constant searching for a signal. Sitting at work, full strength 4G signal, it only heats up when the screen is on for an extended period of time.

JuiceDefender works fine on the Rezound. The problem is that the Rezound doesn't benefit from JuiceDefender as much as other phones do, mainly because it suffers from a different problem than other phones.
JuiceDefender's strategy is to shutdown nearly every radio and process in the phone when the screen is off and there's no active communications. This works, in the sense that if you turn off the screen with 98% power, you can turn it back on a couple hours later and the phone will still have 94% battery remaining. You won't get that kind of battery life if you're running a bunch of widgets and syncing email without JD.
But the Rezound's incredible screen (and even now it remains one of the very highest quality displays in the industry) draws a lot of juice when it's running. Not coincidentally, this is also the time when the dual cores are running at maximum speed, and the heat you feel on a Rezound that's been screen-on for a few minutes is the milliamps getting sucked from your battery.
Still, JuiceDefender can help here, too. You can tinker with the brightness curve to reduce your backlighting even with the dimmer set to "Auto," and you can tinker with the CPU speeds and the governor strategy. The phone does not need to run both CPU cores at full speed to feel responsive, and yet that's what it does by default. In the Ultimate version, anyway, JuiceDefender does a good job of capping that. In fact, with the right settings I can operate my phone indefinitely without overheating it. And any heat you can't feel is energy that's staying in the battery.
JuiceDefender does work. But it helps to have reasonable expectations. That display does draw a lot more current than most other phones, and this does limit your screen-on time no matter what else you do to conserve power.
I never really cared for JuiceDefender back when I used it on my Evo 4G. It seemed to just barely save me any battery and having to wait for the radios to turn back on after every unlock was annoying me.
I will suggest that if you have the Facebook app and you're regularly using it, it might be taking up tremendous amount of battery. If you want to keep using it, at least disable it from syncing.
Also, TurboProp works pretty nice in extending my battery life. I don't think it's just a placebo, either. I can go over 24 hours on a single charge thanks to it, and that's for the stock battery, too.

Very good explanation cpurick. Totally agree with your assessment that the cpu cores need to be capped. Do you mind sharing your JD settings?
