Battery Drains to early!

hey people tell me what could be the problem?? My battery drains all in a day or sometimes i have to recharge it twice in a day, but without any use it drains in two days?? what do you think is the problem?? Is the Battery Weak???
Second if i wont to buy a new battery how many mAh should it be?? My current is 1250mAh. Would a 1800mAh be of the same size as this one? will it work and fit fine in the case??
Please do reply. Thanks in Advance.

First, some more information is needed:
Are you overclocking? This is the single most likely candidate for faster battery consumption.
Are you running anything that requires a lot of processor power? Animations like the TouchFlo Cube and PointUI are hard on batteries.
How old is the phone, and subsequently the battery?
Are you leaving a lot of programs active but minimized? This can also hit the processor harder, which results again in faster battery drain.
With regards to battery replacements, I will let someone with experience in that area give you suggestions (and I will eavesdrop, because I have an old phone and am concerned about replacement myself...).

1. Im not oveclocking
2. Im running Touch Commander Suite
3. My Phone is 2 years old.
4. I leave no program minimized except one tht runs in background.
Now what can you advice?

The 1250mAh is the standard size battery for the Wizard. Anything bigger than 1250mAh will be thicker and need a bigger battery cover. I replaced mine with a new 1250mAh after 18 months of use because I didn't want to make my phone any thicker.

How much time does your new 1250mAh battery takes to discharge:
1.When nothing spcl is done except reading SMS or Calling?
2.When loads of work is done like listening songs, watching videos, using Wifi/GPRS?

How about WiFi? Do you leave it on? How about GPRS? Both radios are power-hungry, and should be shut off while not in use. Sure, it means a little wait on starting programs that require a connection, but it also means having enough battery to finish what you're doing. Which, if you've ever been lost in a strange town without a Thomas Guide, you'll agree is damned important.
Short of that, and the obvious (and relatively cheap) alternative of buying another battery, I have to point the finger at Touch Commander Suite.
Run Task Manager 3.1 (Dotfred) on your device. If TCS is using less than 5MB while running, I'll eat my hat (you'll just have to trust that I've eaten it, though... ). More crap in RAM means less battery life. It's not as dramatic a drain as the WiFi radio (the worst culprit of all), but it's probably in the top 5.

1.I dont leave anything on when im not using it.
so What would you say? should i remove Touch COmmander and install SPB Mobile Shell or anyother SPB software? will they be less battery consuming?

...
hasseb try a diferent rom...it may be the software that is draining your battery....anyway a battery shows signs of use after 2 years and a half....so if another rom doesn't do the trick...i think it's time to buy a new 1250mAh battery...other batteries can damage your phone because they have a larger energy output....and congratulations...you are a senior member now

Thanks for the info and thanks for congratulating me on becoming Senioe member. I guess the real problem was Touch Commander Suite, i uninstalled it but still timing is less so i have to buy a new battery.

high battery heat !

when i listen music for about 30 mins + and running some programs such as adobe reader or opera, i can feel a warm in my hands from the battery. actually its more like to be said a relatively high heat felt by my hands !?
is this high battery heat normal? i mean for an everyday usage.
tnx in advance
Note: i did search but didnt find anything about LEO battery heating.

The battery can sometimes get quite warm, but it should never be hot. If it heats up to much you should probably get it looked at.
The battery in the HD was a lot worse than this. I think there may have been some issues, but HTC have worked on it. Thankfully, I don't know of any HTC phones exploding anywhere yet! lol

mine gets hot as well some times especially when I use igo in my car and charge the phone at the same time but also when playing a game etc.. but I read in the manual that this is normal... although I believe heat to an extent that can burn your hand its not normal.... mine never got that hold
just my 2 cents

Hello,
If you are using something like Opera, coupled with a number of applications that are cpu intensive, then you are going to get high battery drain which equals high heat output. Some of the heat will be coming off the cpu as well but the end result is the same.
The problem is worse if you are using wifi and/or gprs and you are in a low signal area, which means that the device and the battery need to work even harder to serve your needs.
If this happens again then check your location relative to wifi and gprs and/or reduce the number of intensive applications you have running at the same time.
If this fails then you may have a fault; however I think one or all of the factors mentioned above are linked to your issue.

ok tnx for replay guys...i accept this as normal situation, and yes i definety like to use igo8...and really its soo nice to have pda such LEO that can easily open and run several such programs!

HTC HD2 - Lower CPU clock when sleeping?

1Ghz of Qualcom CPU seems to consume a lot of energy. Does anyone know how to lower the clock when it's sleeping as HD 1 can do??? I'm asking this question 'cuz the app for HD1 does not work on HD 2 (different CPU?). Thanx in advance.

i got an entire day from 9am to midnight running video for over an hour and using the phone througout the day. the battery seems to die faster at first but that last 50% is a real stayer. i had to try very hard to make it die and i wasn;t able to do so before midnight.
it's a good idea to clock down to save power but i am not sure how much it would save and if it is really worth it.

As far as I know this is already a built in feature of the HD2

that wouldn;t surprise me however IMO it'd be a chipset feature of the snapdragon.

it's built in... snapdragon when system don't need full power change clock to around 450mhz...

True. Search for LeoCpuSpeed. App that measures your frq and you can boost too...very handy

Overclocking

I was wondering if anybody would be so kind as to give me some pros/cons about overclocking my phone. Or a link to a topic as I'm sure there already is one, I searched but could not find.
Thanks,
Stew

PROS: Your phone goes faster!
It goes slower while it's asleep, so more battery (as long as you program the profile in setcpu)!
CONS:Your phone might overheat.

Thanks man I appreciate the response. When you say overheat do you mean the battery, or the actual phone? haha

Why would one, and not the other? They are touching, and crammed together....

Idk just thought I should ask....

I just figure the phone has a failsafe. I have mine at 768 and only gets ridiculously hot when charging running Google navigation. Otherwise it's just slightly warmer. When it overheats the led flashes red green and I figure its slowing the charge or stopping it to compensate.
A computer will shutdown when the heat gets to an unmanageable level to prevent damage. I figure the phone would have something similar.

It doesnt go faster while its asleep.. It scales down like any other rom/kernel would when the phone is asleep.
If you really arent sure then dont ever use an OC'ing app. Just install the kernel and let it scale on its own.

Also the only thermometer thats close to the cpu is the battery. So its not the most accurate thing to watch since its not the actually cpu temps. Just a rough estimate. Also when it get to around 40 C then set the max clock down to around default clock speeds. Or simple just let the phone relax and dont touch it. You can also take the back cover off and let it get more air..
It doesnt get hot extremely easy, so its not like youll be sending a text and it gets hot. Its only after prolonged use or doing something thats keeping the cpu from not scaling down very much (game, tethering, or etc..)

I think he meant setcpu can scale at a lower then factory frequency. But that would actually not be overclocking =P

It would actually be underclocking, yes. But it DOES give you better battery life!

I haven't noticed a difference setting my phone to 245mhz when it's asleep (well positively anyway). But when I unlock it is slow to a crawl, so I just set it 528mhz all the time and my battery life is unaffected but my phone is always very spunky.I don't have fresh toast on my phone so I haven't overclocked it yet (but may eventually)

I only had issues with overheating when charging, especially via USB to a computer. One commonly overlooked side effect is that Li-Ion batteries lose capacity faster at higher temperatures. The capacity degradation is a combination temperature, charge and number of charge cycles. The ideal situation is to be at 40% charge at 0C, but the hotter the battery, the more it degrades with time.

Could this be the source of poor SOT?

I came across some strange CPU behavior on my Exynos Note 4, and I wanted to see if there's a pattern between the SD805 and Exynos versions.
First, I used this app A1 cpu tool to get a real-time measure of cpu clocks. I installed it on both my Note 2 and Note 4.
Now, when I hover my s-pen over the screen (enough for the cursor to show) OR touch the screen, the CPU jumps up to 1300mhz (max power). On my Note 2, it will only get up to 800mhz (half of it's max CPU speed), which leads me to believe that the Note 4 is being too aggressive with CPU scaling, and it's resulting in poor screen on times.
I'd like to hear from both SD805 and Exynos users to see if they exhibit the same behavior. There should be no reason why Sammy is cranking the CPU up full tilt just to keep the s-pen cursor on the screen - or to handle touch events without anything major happening on the screen itself.

Hmm.. good observation and findings chap.. lets see what samsung has to say er... or any devs

Interesting, but if you have poor SoT, this is not the cause.

It certainly could be if my device use involves a lot of screen touch events (i.e. not watching movies). I type a lot on my phone, and if the CPU is running a full power for each key press, it can certainly cause more drain than it needs to.
EDIT : I will add that bench marking for battery life WITHOUT touching the screen gives me very respectable times. SEE SCREENSHOT

There have been more people complaining about poor SoT - the probability that all of them are using the stylus in such an intensive way seems small.
I can testify that I also use the stylus taking notes during meetings, sometimes as long as 2 hours. I never noticed a SoT reduction because of this.
However, it may be useful for you to post your battery usage stats. We could get a better understanding of the root cause. BTW, are you rooted?

Interestingly, simply hovering the s-pen over the screen will ramp up the CPU too... I have a hard time believing that it wouldn't impact battery life.

Are you measuring the consumption, like in drain per hour or something like that? I notice drain between 12% - 20% per hour simply depending on very minor differences in usage (i.e web browsing vs. tweeting). I tend to use the stylus a lot.

I am rooted and get good standby time and expected battery life (i.e with gaming). But regular SOT sucks and I barely pull 4h most days.
I'm hoping that Snapdragon users can confirm whether their device ramps up the CPU on touches too, or if it's just Exynos models (that could explain why people are experiencing such a variation in SOT between the two chips).

I wonder what happens if you still type a lot, but without using the stylus. That would measure if it's the touch events themselves or the stylus hovering.
When I said before that I don't see a SoT reduction while using the stylus it was just a subjective impression. I didn't actually measure it simply because I didn't feel it's worth measuring.
If you're right about this, I really hope Samsung comes out with a solution.

Benchmarking with actual touch events would be very time consuming, but if I could disable CPU throttling for touch events, I could test with general use.
I read somewhere that this could be done, but I haven't seen any cpu control apps that do it on my stock Note 4 kernel. Perhaps it needs to be custom (or changed by Samsung)?

So, this is what I was talking about: http://forum.xda-developers.com/showthread.php?t=2532422
"input_boost_freq = Boost CPU speed to this frequency on touch screen events. Measured in MHz."
I would LOVE to be able to adjust that on the Note 4! I believe there's either a bug or an over-aggressive use of this function.
