[onecosmics' ics rc2.1] super duper mega extremly bad battery life .

First of all , I really like the work onecosmic has been doing , keep up the good work !
I am currently using the RC2.1 build combined with fugo kernel . so far epic . I'd really want to use this rom on daily basis but the problem is that i get horrible battery life. at first I reflashed everything (including all wipe needed in the order specified) but that didn't help . I am currently on my 4th or 5h cycle of calibration but it gets worse every time .
here is a screen shot from the 2nd cycle (started fully charged ):

i lost 75% in 5hrs of normal+- use . :\
here is one from now (started fully charged )
40% in one hour . i played a couple of games for 20 minutes and thats it . it dropped me to 79% and than i stopped using my phone . the battery dropped alone to about 60% short time after that .
What can i do to improved it ? I tried to avoid widgets , reflashing and wiping , other kernels that seem to mess up my rom and get the home button not to work (nushors) ...
I thank you all in advance for your , I hope you could help me solve my problem

Check in battery settings what is using your battery so much.. if anything other than Android OS (could be till 30-40%) is consuming your battery.. take action regarding that..
if this doesn't work, then clear your battery stats through recovery and calibrate for another 3-4 full charge/discharge cycles.. should solve your problem

Tried everything . battery still sucks

I think it's the HSPA/WCDMA network type. I use GSM only and I get 1day +.

You forgot to post most importat thing, how long display was on. From screens I can see it was on alot.
If it had 3-4 hours, it's probably okay since you had data enabled aswell.

try buid 13 teamhacksung.
I'm on it! And it's better than CM7.

What means better than CM7? Can you give an example: e.g. 2 days with normal usage.

I don't have good battery life too. We just need to wait for devs to improve it...

music player not working
video player not showing all videos
can't add or remove homescreens
m on glitch kernell

Okay, means we still have to wait.

Ok, did you intall the rom with the battery full charged? This may be the problem

@chriss23: how is your battery expierence with build 13?

i am on the second battery cycle with onecosmics mod. normal use of the phone and 63% left after 32hours. its ok but when i use some apps the battery drains one percent on only a few minutes. iam unsure if this is normal. usage of android os in battery stats says 26%.. in gingerbread, this was too much but would you say its normal on ics?
thank

Hello all. I had also battery issues with the new roms of ICS. I exclude usage of data which one way or another makes things worse. I believe that issues will be fixed soon since the difference between the first versions of roms and the newest ones is significant. Freezing also some unneeded background processes always help (i use titanium for this). Playing among different kernels and undervoltaging can also help.

Too fast battery drain

Well that translates to 33 hours of battery life so that's pretty good
This phone is different from others in that the lowest frequency (384mhz) is very high (my nexus 7 stays at 104mhz a lot), so minimizing the number of apps that make use of the phone when it's locked is key, as they would make it run at 384mhz, stamina mode is good with this but I assume you already have it on
So try to search for apps that use services that always run in the background and uninstall the ones you don't use very often

The same thing happened to my SP but only for 3-4 days after flashing a rom, then it was stable and the battery decreased from 100 to 15% after 2 days (light-use) or 24 hours (3G and Location based Wifi were on, without Stamina or Low battery mode enabled).
So, have u flashed rom already?

1% in 20 minutes when display is off. i charge my phone after 15-17 hours. that's how much it actually lasts.
Stamina mode is not enabled. i will try with it too in few days. thanks for the advice though

It's interesting to do experiment with these Mods, but sometimes we have to pay the price by time and even brick!

i bricked my galaxy note once. it was a night mare which i wish never to see again:fingers-crossed:. Nexus 4 should have been a better choice this time but i din't knew SP had odexed roms

Xperia V always active

Spoiler
Okay, first of all, I'm on an Xperia V, with latest firmware (4.1), unrooted.
So lately I've been having trouble with battery life. I don't really use my phone much, since I've got a Nexus 7, but the phone just plows through the battery.
The problem was that the phone always stayed active, even with battery saving modes on. Now I didn't use many sensors, like GPS, NFC, BT, and WiFi Location, but still I couldn't get it to last very long.
Now two days ago, I factory reset it and set it up. I tried Smart Connect and Location Based WiFi to automate my phone, and battery life was pretty good, definitely better than previous.
But now today, my battery life is once again bad. I haven't really found the source of the problem, it's not an installed app that drains the battery, and the battery usage shows that 'Media' and 'Android System' drains the most battery, and that the phone stays active when it's sleeping.
I've also noticed that my signal drops frequently, even though I'm in the town.
What can I do?
TLDR; Xperia V, latest 4.1 firmware, unrooted. 'Media' and 'Android System' drain most battery, phone stays active all the time, no GPS, Location, NFC, BT. Tried factory reset. Don't know what to do. Frequent signal drops too.
I'm gonna try a factory reset without the SD-card, I don't even use it.
Here are battery and wakelock screenshots:

Err, that is normal use.
Your phone is in deep sleep for 49% off the time, that is normal. You have 38% battery after 21 hours use, that is good.
If you keep factory resetting then every time you boot it has to use media scanner again to rebuild its data bases..
My suggestion I'd to leave it for a few days to settle down, then see how it is

No, it can't be.
Android System and Google Services shouldn't drain 70% of the battery, neither should it keep the phone active 75% of the time, with less than two hours of screen on time. My Nexus 7 has been 'active' 20 minutes, with 5h of screen time and music playback.
I had the problem before, that's why I reset the phone, and now I have it again. I don't think it'll settle down.

You can always ignore my advice if you want.
But your own images show 49% deep sleep and 33% battery left after more than 20 hours use. Trust me this is good and normal, and most users here would bite their right arm off for that
Also, if you keep resetting you are going to drain the battery quicker.
But like I said, you are more than free to ignore this advice and keep resetting your phone.

I'm not ignoring your advice, I'm not resetting, I'm just trying to find an explanation and a solution. Thank you for your answer.

[Q] Poor battery life

Hi!
I've searched the forum but didn't find a straight answer. What's your battery life?
Mine, having no apps, few notifications, black face and always on get just 13h. And that's frustrating. My unit it's just three day's old and if this is the expected performance I will return it at once. What do you think?
Thanks!

I'm getting over 2 full days easy. But I also have enough ambient mode turned off so the screen is completely off, unless I get a notification or am using it.

Just a update before I put my watch on the charger.
2PM on the 19th to 8:35PM on the 21st

I usually get 2-3 days with moderate usage. Always-on screen enabled seems to be about the same as when it is disabled for me so I leave it enabled now. However, my watch screen does shut off from 0000-0650 hrs everyday. If you aren't playing with your watch a lot then 13 hours seems unreasonable.

I just checked mine : 72% remaining after 13 hours. Always on enabled - used lightly (notifications and some small utilities). I'm charging it every evening though .. just to have it 100% in the morning.

Thanks!
After a watch reboot it seems I'm getting a couple of days of battery life. I imagine I had some mysterious app depleting my battery. So I'm keeping the watch.

I have also experienced poor performance of my LG G Watch R. It will drop from 100% to 0% charge in 4-6 hours. When I look at the AndroidWear log, it shows about 15-30% power drop over various applications. I am then questioning where the other 70% power drop has gone.
This is extremely frustrating. When the Bluetooth is off on my phone, the power drop is as expected - a few percent every hour.
Anybody else have this issue? Could it be my phone? I have a Galaxy Note 3 on the Verizon network.
Thanks for any suggestions.
Cheers,
B.D.

Yes, I also had the issue today, already for the 2nd time in the past 2 weeks. Something happens and the battery starts depleting quickly ...
Any idea how can I see which apps have caused this rapid battery drain? Someone mentioned android log ...

I'm getting 2-3 hours of battery life. I've had the watch for less than 24 hours. I realize once an update is done battery life isnt optimal for a day or two on Android but this is nuts. I have screen always off and haven't installed any apps. I'm gonna give it to Monday and If I'm still seeing this drain, It's going back to Google.

I read recently that there is a bug in the battery meter when watch is shipped. It will show 100% then drop very quickly for first few days. I've had mine nearly two weeks and I get through a shift at work (8hrs) with 60%+ remaining. I work nights so I keep brightness set at 1 which probably helps. Hope it gets better after a few cycles.

Question Battery draining a bit too fast

Hi!
I'm experiencing some battery draining problems for a few months.
Overnight it uses up to about 15% and during the day with about 1h30min SOT it's down like 30%. I factory reset it, debloated it, dark mode on, Naptime with aggressive doze mode on and restricted almost all apps from running in the background with no difference.
I'm running on 12.5.4 global. Sometimes cell standby uses as much as 500 mAh.
When the battery is full it says "about 52 h 34 m left" no matter if I'm using fast or slow charging. Is this normal? I'm attaching some screen shots.

No. Unfortunately this seems to be the worst phone I have gotten so far and it's one of the expensive ones I bought. I also have problems with it not updating even though I did factory reset and tried to use select update package.

I have flashed the latest Lineage OS a week ago and the battery life is very good! The best of all MIUI or AOSP ROMs I have flashed to the moment!
At night the phone is in sleeping mode and the battery at morning is almost the same as it was at the evening, with WiFi, Bluethoot and Location switched ON - I haven't really tested how much exactly percents it tekes during the night, but I think that it's not more than 2-3% for the night.

indeed sleeping mode in custom roms is magic, but if you forget to activate it.. well good luck waking up to your alarm

Below are some stats from the latest Lineage OS
3% for almost 8 hours
I didn't get any problems with the Alarm and the deep sleep mode!

Overnight drain is too high. It's 10% even after enabling scheduled power off/on feature. Phone remains powered off for 4-5hrs at night still 10% of overnight drain is too much

2% here for more than 8 hours

That's aosp bruh. I should switch soon.
