Battery drain

Hi I have HTC Sensation, and 1,5 ghz kernel, dar forest rom. And I calibrate battery, and I am after few cycles, becouse some says that after flashing new rom, u must wait a couple o cycle to battery to be good. And my battery last about 19 hour with about 3,5 hour screen on. Is it good or bad, and what can I do if its bad

Hi,
If you are using a data plan and sync data, try increasing the frequency interval or use manual sync. Saves Battery.

Good or bad?
But, how do you guys think is it good battery life, medium or bad?

Its average

I'd agree with average. One thing you can do is install 'CurrentWidget' from the Android market and place the widget on your homescreen. Change the refresh interval to 10 seconds, turn the screen off and then wait around a minute for the phone to settle. After a while, turn the screen on again and look at the reading the widget gives. It should be around 3-5mA (that's what I get on my HD2). If it isn't you may want to try turning off different wireless things and anything you think may cause high battery drain. Turning off background data is a MUST, you have to turn it back on to use the market but with background data off I get 3-5mA whilst with it on I get around 20mA. It doesn't stop you using data, just turns off some unnecessary syncing. Despite the pathetic 1230 mah battery in my HD2, I can easily use it for a whole school day (including music on the way to school and gaming for about 20 mins before registration) and have around 40% left by the end of the day. I charge it every night anyway but it's reassuring to know it can last me that extra day if I need it. Hope this helps

if somtimes play games, music... it's normal but if you sometimes call or sms it's not good

ok
Than what is good?

average like other said..if you dont do nothing but calls and sms and it lasts like that..that would be bad..more use=more battery drain.

Try using wifi as often as possible. Also 3g is a much better battery saver than using WiMAX. Also the Tiamat SBC 4.1.0 kernerl is amazing on saving battery life! And it even works with the ICS roms.

19 hours of battery life sounds reasonable to me considering that the sensation is a dual core phone.

Oh and by the way I've recently come across articles that actually say recalibrating (wiping battery stats) your battery doesn't actually do much.
I'd rather try to avoid over charging to prolong your battery life (pull out the charger as soon as it touches 100%) and try to use it til you're out of juice instead of constantly charging.

I read somewhere, that for Li-Ion battery is no difference, that u charge it when its empty or little bit at the time.

Yes, but with Tiamat SBC 4.1.0 kernerl i dont have 1,5 ghz. And also I never flashing kernel alone. Always it goes with roms. Can I change kernel without reinstaling rom?

Battery drains has many situation, as little information you provide, it's hard to figure out how and what makes this happened.
Maybe you can check how many apps running on the background, or services still running while shouldn't run.
Or, tell you what, you also can flash your ROM to a stable one like ARHD's rom.
my 2 cents

I am using darkforest rom http://forum.xda-developers.com/showthread.php?t=1423684 tell me why ARHD is better rom, I had it for 5 minutes, but shame that this rom dontt have such simple stuff as Stock % Battery, and advanced power menu and quick settings. Ho do you think why ARHD is better than dark forrest, what are the main differences?

One X Battery Life

Is there a need for a battery saver app on your phone if you only turn on things like wifi or GPS when you actually need it? I read through the descriptions of some of them and most just manage when to turn data on or off and I do that manually so they seem unnecessary.
Additionally I just flashed Cyanogenmod 10 and calibrated my battery, but the battery life still doesn't seem to good, it drains at about 10% per hour (when I first flashed it it was ok, the 10% per hour just started today). As I said I only turn on power intensive services (wifi, data, gps, bluetooth) when I want to use them (I don't constantly turn them on and off either), I don't have anything set to auto update or auto sync (as far as I can tell), and my screen brightness is set to 0% (I'm usually inside).
The 10% per hour occurred simply when I was texting and using wifi, even then it was mostly texting.
Is there anything I am not checking for and is there anything else I can do to improve my battery life?

You are fine that's just how it is on some roms

[Q] is this battery life normal?

i have the dual sim version. both 2g. NO WI-FI AT ALL.
I usually get 3- 4 hours of screen on time. then im under 14% i just use whatsapp, a little gaming,opera mini browser. with this usage i get total 14-18 hours of battery. is this normal? my previous phone was nokua 5230 with inane battery life.

not sure..
My battery life is better i think but cant say if yours is normal ... Screenshot of battery stats would be helpful

I charged in the middle upto 80. Screen on time at that time was 3.5 hours

Hmm..your battery life doesnt seem Bad to me, but I cant tell you if its actually a normal or a Bad battery life as i have the single sim Version with tweaky one Rom and faux kernel... Sorry, that i cant tell you more, but i saw some battery threads here at xda already, maybe you should ask there. Good Luck.

1. From screenshot it says 3G.. You sure you are on 2G all the time or this was just rare case?
2.From graph it seems like you charged phone in between from pretty low to quite respectable 70 - 80%.
3. I get this kind of battery on medium usage with single charge. So if you charged in between then your battery seems poor.
4. Do check background services running and disable what you can.. From usage you specified, you should not require many running things. Use greenify to automate this things.

He says he uses WhatsApp as well? Does it work on 2G connection too?. Thought I'd point out.

If that is the case then you are definitely having less battery life buddy..
What else is running in background?

i had acdisplay but i dont use it now because i think it's eating up my battery. i have avast free, messenger, WhatsApp, clean master, dashclock widget and battery extenson . camera 360 is a bit nuisance. i close it but it starts again. also u should know that my phone was fully discharged two times when it was new
due to my carelessness. but i immediately charged it.
edit: also chrome on 2g takes up 1 or 2% every 3 or 4 minutes. it takes 3 or more hours to completely charge it with Motorola charger. I'm on GEL. got it from android police.

[Q] battery percentage falls abruptly

I have noticed that after every full charging when Battery percentage reach at 30 , from then within 10 min it falls down to 15 percent....i have tested it twice or thrice in standby mode.. What should be the reason behind it???

Make sure that all the windows are closed, Phone brightness and timeout is low, and also make sure that your battery properly fit to the mobile sometime due to this battery fall down fast.

ya i have checked....battry prblm ho sakta hai????????

Its a common problem. One desi solution for it is swith off the phone while charging and let it charge completely. Then swith it on while plugged in.
Do this atleast once a week, it solved the problem for me.

Also if your battery is more than 6 months old, consider changing the battery as the average life for micromax batteries is 7-8 months depending upon how many times you charge and discharge it.
In my case, i've to charge it atleast twice a day. Maybe because of this my stock battery bulged in 7 months.

this is what they call battdrop.
its pretty common to all

Battery problem can be solved with Kernel Change

Guys i can confirm that the battery drain problem has got solved in my phone. Running mivo rom with Kashif kernel now and no battery drain. Also checked Darky kernel v2 no battery drain.

yes, custom kernels might solve the battery issues..consider also the battery itself

Wipe battery stats
Mostly it is not the battery as the drain will be at the same rate. it usually is because of the software. You can also try wiping battery stats.

help Rom mess up my new battery

Bought a new battery
Used NamelessRom for a two days, and now my battery goes down to 50% normally, after 50% the screen goes black and phone power offu
If I try to power on, can't get even the screen on. Connect the phone to charger, boots up at 0%, instead of 50%
Go back to stock, and tried to calibrate the battery in any ways posible (supercharger scritps, leaving the phone all night charging, battery stats erased) and no luck
The voltage of the battery full charged is 4180mv (the highest value I have reached) and the minium with 0% es 3476mv
What happened?
PD: Also recieved a DM from @kael.yagami and he said the 4.4 roms have messed up with two of his batteries too.

Greetings;
I've never tested the nameless rom. And i got the same problem.
And yes.. I also had a 4.4 rom before.
Yesterday i tried:
delete the battery stats under cwm; installed "battery calibration" application.
Charged the device until full; pressed "battery calibration" button (inside the app; then gave an exaustive use to my device so i could drain my battery faster; charged the device again and so far seems ok. Im going to give another exaustive use to see how it behaves.
I also noticed (yesterday) that at reboot battery percentage gets mad by displaying:
i.e last night from about 50% (52% to be precise) to 5% instantly just with a reboot.
I went: wtf!?
I am using DDLF2 rom.
There may exist an explanation for this.
But it is too much coincidence to be the 3rd person that has installed a 4.4 rom.
It is possible though...
A rom that was designed for specific hardware/devices can make different harware and battery usage.
Due to that reason it lead me to try some alternatives.

I used kk roms in my sl since the beggining and dont have problem with battery. Its your new battery original? May be you dont know that wiping battery stats.bin you are misscalibrating your battery, thats why you have wrong indication level. Read a bit about that.
Sent from Mallorca to your face

I always thought battery stats were only "Battery Usage Information".
Didn't knew that it could mess the calibration. Wich Acording to this website:
http://m.androidcentral.com/wiping-battery-stats-doesnt-improve-battery-life-says-google-engineer
There are no effects on battery. And like i said: status info only.
I've been searching for that but couldnt find info regarding de-calibration when batterystats is deleted.
I actually do it whenever i flash a new rom. Never had a problem until now. But i dont believe it is due to the Battery stats.
Wakelocks maybe?

Ok i found my missing part of this in wich i didnt knew.
It is confirmed that battery stats stores information.
By deleting the battery stats there is no harm for your battery.
What happens when you delete the battery stats is you will delete all the infomation the battery uses to perform better.
Erasing battery stats and
Recalibrating is good when you flash a different rom. But not necessary.
The catch is whenever you delete the stats you will have to let the stats be build again. And that will take several days (if not weeks or months of charges).
Only then battery will perform on its best.
I can confirm this fact with my other phone.
It started to last 5 times longer than the day i bought it.
In this case to be precise since the last batterystats. (it was in January).
I dare to say that my other device lasts until the very last bit of battery. Wich is awsome!
Note that you can recalibrate by letting your device discharge completely (until it wont even turn on); charge it untill 100%; done.
