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.

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?

[Q] Phone dies at around 40% new battery

So I've bought a new battery for my nexus s and the problem is that it shuts down at around 40%, then when I plug it in it will show 0%. I looked around the forums and I have tried to calibrate the battery by resetting battery stats, draining it and then charging it to full. I have also gotten a replacement on the battery, still the same problem. The difference of these ones are that it is 1440 mAh and the original is 1500mAh. Does anyone have a suggestion to fix this problem?
Many thanks

What ROM and kernel are you using?
Either way, try a new or different ROM with a different kernel to see if does it on that one too.
Good luck

I'm using XenonHd rom and marmite kernel , I'll try and flash a different rom later. Also I don't get the problem with my stock battery it just happens on the other one which is strange. But thanks I'll give your suggestion ago

Yeah that's what I thought too, but another theory of mine is that its 60mAh different from the original so that have messed up battery meter on the phone, I've tried changing the kernel but still the same thing happens. I'll keep on trying to calibrate the battery meter to see if it makes any difference

Hi, it seems to be a bad "new" battery, anyway, to be sure, try to have a look which of your apps are running in the background, try to find if such app can cause a huge battery drain.

And also, it seems your signal from the your operator is not very stable (=battery drain) - try to switch 2G only, try to switch-of wifi, on your screenshot - the battery collapse comes at 70% (?)

Update, I have just installed a new rom and kernel, and I think it is just a extremely inaccurate battery reading as it would also turn off at 40% on the battery icon in the status bar ( The graph shows that it dies off at a higher battery percentage which I'm not sure why". But after it dies, I can turn it back on and it would still have some battery life left, approximately another 20 mins of usage before it goes completely flat. So I think wiping the cache/davlik or installing the new rom made a slight difference.
'pgcz' The huge battery drain you may see from the battery graph is not battery drain, but it is me using the phone, playing apps etc. until it turns off so I can get a screen shot to upload onto here but thank you
I will keep on trying the battery calibration method I've found which hopefully would help, otherwise I'll just leave the situation as it is and keep the battery as a backup one

ok, I understood your graph now, anywat, if you are going to run new rom and kernel, I can recommend rom Jelly Shot v.3.2 (or upper) with Marmite 8.4 CM kernel

Battery Lifespan?

How do I know when to change my battery?
I'm using cm10.1 07/14 for 5 months now without issues,but for past 3 days 5-8% battery discharge during standby, heating on charging or web browsing or even ui browsing and unusually low RAM.
Or is it some apps or games I've recently installed. I suspect that it might be new version of AVG antivirus, any ideas?
Please help! Thanks

Is your battery OEM or third party?

Other than the battery/charge issue, the cm11 is awesome!! Thanks to Scott!!!

Using original battery. I'm on cm10.1 14/07 a.k.a Android 4.2.2!
Deleted some games and apps and battery is stabilising a little during standby, but on slight use it loses 8% minimum!

Have you flashed custom ROMs on the phone? If so, you should go and get an app like Battery Calibrator, which could recalibrate the battery and display the proper battery percentage. It's possible that your battery is fine, but your phone doesn't know any better since flashing ROMs mess up the cache.

Battery Drain For KitKat 4.4.2

Anyone encountered battery draining after updated to KitKat XXUENA6 via software update
Sent from my SM-N9005 using xda app-developers app

Think it just needs a couple of battery cycles to even itself out.

I'm getting some decent battery life - about 20% more per day, for my average usage (ending the day around 65%), than stock (rooted). I'm running Omega v7.1.
As suggested, give it a few cycles.

yes, I have,
I found it's because the EMail sync, if I disabled mail sync battery life is better.

I have problem with my android system, it's drain more battery than my screen on.
I just installed BBS, Gsam Battery Monitor, and Watchdog but I can't get the infromation what did android system do with my battery
Anyone can help me ?

Since 4.4.2, leaving my phone overnight would drain 0% battery (or sometimes, very rarely, 1%).
I'm using Greenify (I Greenify everything except WhatsApp and Nova Launcher) and on a typical school day I can end up with between 50%-60% of battery.
The more draining things I disabled include Google's location reporting service and always-on WiFi scanning. Perhaps you may check

Battery life is really bad , not as good as it used to be , certainly not as good as my Stock Note 2 was!!!!!!!... please any suggestions?
Nothing works,tried all the tips around here (except for rooting), before kitkat (on jelly bean mj7) I used to have that annoying android os bug, when I received kitkat, the bug was resolved but got replaced by another unexplaicable drain by "android system" !!!!!!!!!!!!!!!!!!!!!!!
" android system " and " media " drain are too Damn high... 2 hard resets didn't even help at all.... And I'm on the gsm only mode with gps off all the time.......
I'm really getting fed up with Samsung and their crap software , this is my third note device and the most buggy one... and it's really getting ridiculous ...
Any suggestions would be highly appreciated.
Cheers.

All in necessary bloatware disabled. Sync on. Olways with wifi in home or 3g out. Locations disabled. Amazing battery life .

Same here. My Android System is next to the screen with 30%
Gesendet von meinem SM-N9005 mit Tapatalk

mine is at 20 %. screen at 18 % haha . still got 4 hours of on screen time with H+ on all the time , autosync , and semi debloated ( as much as possible without root ). No location or freaky stuff.

have problem with the Android System also. I'm now at 25%, Android System 37%, Screen 24% (2h57m). Location, Sync off. Hope someone can help with this. Thanks.

Same here, android system is the second consumer after the display. Very bad battery life after kit kat. On 4.3 i was getting 2 days easy and now under the same condition i get 1 day.

Hmm are you on ORO? I'm from bucharest too but let's talk English here
Anyway mine today seems stabilised. Android system is the second one now but still kinda high...

I'm on NC2 now. I have an unbranded phone and i tried all firmwares from sammobile, some with full wipe and still have battery drain. I even began to get rid of some apps but i don't think it is app related. I had exatly the same apps on 4.3 with much better battery life.

Having horrible battery life with my Note 3 after the update. The android system shows up using 50%.... It's been 4 hrs off the charger and I'm already down to 70% battery life. Just horrible.

I have a question for everyone who's suffering from the battery drain in KitKat and who seem to have Android System at the top of the list constantly:
Do you by any chance have a service called gsiff_daemon as a major cause for battery drain? You should be able to check this with Better Battery Stats or Gsam Battery Monitor apps.
I'm just trying to find out something and I could be wrong but it would be good to hear from people who have a draining battery.

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.
