[Q] Best battery life?

Hi,
I just recently bought my Inspire and rooted/s-off/eng s-off.
I flashed Android Revolution and I can't stand that I can't have my phone for more than 6 hours before 15% battery.
Is there any other ROMs that have better battery life? I'd rather have something like an optimized stock, but I really would love better battery life.
If you're wondering, I don't do a lot on my phone--just music, texting, and mild web. No video, and some e-mail.
Thanks~

For me, CM7 has better battery life than AR.
It's AOSP though so no sense. Though honestly I don't miss sense at all. In my experience the only feature that sense has over stock is the dialer and camera.

How long were you using Revolution? ROM's need some time to even out in the OS. At first they'll rip through the battery like nobodys business. Also, did you reset the battery stats? I'm pretty sure that is in the Revolutions FAQs. I could be wrong though. Also, the ROM in my sig is a great one to try. He also had a sense version if that's your bag.

Phone Battery usage statistics
I flashed CoreDroid V5.1 two days ago, and i'm sad to say i'm experiencing similar DISMAL battery performance. I've ran specific tests on it all day today, and this is what i have seen thus far:
08:12 - 95% - Airplane mode ON
09:46 - 91%
11:32 - 86%
12:30 - 83% - Airplane mode OFF
13:27 - 73%
14:33 - 62% - Airplane mode ON
16:30 - 44%
These stats were taken with the phone NOT IN USE. The screen was off and it was sitting on my desk. So, as you can see from the list above:
with AIRPLANE MODE ON - a loss of ~3-4% per hour
with AIRPLANE MODE OFF - a loss of ~10% per hour!
This is patently ridiculous!
When airplane mode is on and the phone is not in use, it should be basically on standby, using maybe a percent every hour or two.
When airplane mode is off, 10% /per hour?! That is just INSANE! No WONDER i can't get until even 7pm before my phone is dead!
If it can be determined what is sucking down the battery with Airplane Mode ON, and that 3-4% is eliminated, then the phone should have no problem lasting >14 hours.
(As a note, i saw similar performance before i rooted, so it's not just the ROM)

Moved as not android development.

I don't know if it's just how Sense works, but whenever I view the Applications in Settings, ALL my apps are running, ALL the time.
I don't remember it being the case with my Captivate, though..

Charge your battery till it completely charged. Turn the phone off and boot into ClockMod Recovery. Wipe the battery stats and hopefully that should help with the battery.

If i leave my phone alone over night while i sleep after 8 hours it will be at 93/94%.
Download an app called CurrentWidget. It will tell you how much your battery is being used.
Remember to enable logging so you can check the log latter on your sd card .
With my phone idle I normally get ~3mA or less per minute with spikes of ~160mA once an hour or so.
The max "Screen On" time is about 2 hours per charge.
There is also an app called Traffic Monitor Widget to see how much data each app is using.
These may help you understand what your battery drains so fast.
I'm not Rooted.

I'm seeing some pretty decent battery life on CM7 RC4. Here are some screen caps.

I dunno really. I just took two more screen caps from today. Just my general days usage. I've had the phone for only a week now so I expect the battery to break in a bit more like my nexus did. I was a bit worried about the battery life and this thing lasting me throughout the day but I have been impressed so far. I never even used it with the stock ROM so I can't compare, I dislike Sense.

I've been off the charger for 13hours. I'm at 50% with 1h10min screen on time too. I've had mine for about two weeks now.

I'm running coredroid 5.1 and I fail to see that I'm loosing 10% an hour. Here's how my day was in battery faintly remembering. Woke up at 9:30 took of charger and left for work by 10. From then to I say around 1 I had around 90% only cause I was messing with my build.prop so I was restarting my phone like 20 times doing some test. Also I was ebbing a lot to look for info on what I was doing. And near the end of work around 5 I had even been playing music and games. And was around the 60% I wanna say in the high 60% I played with my phone a lot today and as of right now the same day I'm talking about I'm at 44% and been on my phone like crazy even rebooted a few times again. From what I have been doing to my phone I highly don't see how u could loose so much battery. So from now 10 to to 8 I'm at 44% that 10 hours I was playing with my phone like crazy.
Tips. Use recommended radio's. Charge to 100% clear battery bin. Also give it a few days for the Rom to get built in a little bit. also go download frail CPU its free. It'll help you save some juice when screen is off. Hope this helped.

thats because your phone is sitting in standyby 90% of the time. I've never checked my battery use and NOT had display at the very top using at least 50%. Its not wonder your battery life is great

I have been on many Roms but cm7 rc4 is the best for me. I get about 18 hrs of life with normal usage and gaming. I think Sense is the culprit on other ROMS. Also the free memory on cm7 is 200mb more than on Sense. And this is 90% of the time for me.

I don't think you can beat miui. Pulling 1-4 per min. Of all the roms, I tried this is the best. Ginger with OC kernels too.

If your talking about mA per minute. I get that with my non rooted inspire.

I have noticed something funny about the battery stats on different ROMs. In particular, on CM7, I would never get display as using more than about 10%. On the other hand, when I am running stock rooted ROM, my display always uses about 60%. This is all with similar usage patterns and similar brightness settings. What is going on there I wonder?

I have also never seen my display less than 40%! Even today.
Attached are screen caps of my usage, based on what was happening earlier.
So lets see, display was on 1 hour out of 15 hours. And that = 40%. yea. i call bull****.
Thank you to all for your suggestions thus far. I will try them all out and report back what i have found!

I am heaving very good battery life with CorDroid 5.1 But I also had good battery life with Rev roms. When I am in a fringe service area I switch to GSM only and it more than doubles my battery life with the radio I am using. If I dont need the high speed I leave it off if it is not a strong signal.

CM7 battery life Troubleshooting thread

I am loving this rom, but also having HORRID battery life, I am literally dropping 10% every 90 minutes with an extended battery.
27% Cell Standbye
26% Bluetooth
19% Display
Now I keep reading that these might be false readings, but I keep reading this as a response to those having **** for battery life... so maybe they are not false?
Anyone having good battery life show readings like this? Those with bad battery life, what are your readings?

I'm running the CM7 w/the 2.5 radio - I'm in a 100% full time 4G area, but seem to have worse battery life when the 4G radio is on, so I just keep the phone on 3G - if I need the faster data I can always turn it on and off.
I'm running the stock kernal, no overclocking or setcpu type stuff going on.
Would like to hear from folks running this ROM w/killer battery life, what are your settings, tweaks, etc. Please specify if you're running an MR1 or Mr2/2.5 version and/or running the latest OTA 2 radio that just came out like yesterday.
I just turned off my FB sync (I forgot about that). I don't have gmail set up to sync automatically either.
I'm going to do this procedure a little later today and see if it helps, this is for the EVO, but, ya know....
34. "Calibrate" battery - (1) Turn device ON, charge it for 8 hours (or until LED turns green), (2) unplug and turn it OFF, plug it back in and charge for 1 hour (or until LED turns green), (3) unplug and turn it ON, wait 2 minutes, turn it OFF, plug it back in, and charge for 1 hour (or until LED turns green), (4) unplug it, turn it ON, and use normally.
Anybody else try this?
today will be my first full day of work use w/this ROM so we'll see what happens.

Best to keep 4g off if not using it. Also, turn Bluetooth off when not in use.

i had horrible battery life the first day - then it got better. then i flashed mr2 official and battery life is really solid. getting like 15-20 hrs with 4g always on, bluetooth on sometimes. one important thing is having a custom lighting table which i will post later.

I have never, nor do I intend to ever do this. I got an extended battery for a reason. I can go all day and then some on the official roms, and all of the Sense roms.
I am not new to CM7, I have run it on both an Eris, and an Incredible. Both devices got FAR better battery life on CM7.
I am not complaining about this rom, or Slayhers hard work. I simply want to gather information so that we may help him trouble shoot.

This is exactly what I did lol, I had lost 10% in the first 90 minutes, now I am at 58% at 5 hours. I have been streaming google music for 2 hours of that 5 though. I would guess I should have seen an increase in battery usage, but have not.

The battery readings are wrong, I get a full day on 4G with my stock battery and see those numbers for cell standby etc. I use lean kernel though
Sent from my ThunderBolt using XDA Premium App

do you see those numbers for BLUE TOOTH though? We know good and well some numbers are fake, but that does not mean all.
FYI I am now at 37% and 7 hours and 7 minutes... I have not used google music since the last post and I am seeing the exact same battery drain as when I was using it.

I have absolutely horrible battery life when I'm at work (which is basically a bunker). On a normal day, my battery will be dead within 6 hours just sitting there on my desk.
However, when I am at home (great 4G signal), I see my device getting upwards of 16 hours with moderate use.
I will also say that since I upgraded to the most recent radio, I have been having much better battery life at home. Additionally, my phone has stayed much cooler with the most recent RC + new radio combination.

I heard if you change the render fx to n1 calibrated, then you will get like 1 hour extra of battery life. You can change the render fx by going to cyanogenmod settings.

11h32m11s on extended battery 69% left
The other numbers have to be wrong. Theres no way cell standby is the number one battery user.

my cell standby is also showing 30% with the new OTA 2 radio.

I switched to dream kernel (have not wiped battery stats) and am now at 88% after two hours, that puts me at 6% per hour verses yesterdays 10.

only works for AMOLED screens.
edit: to be clear, it only saves battery on AMOLED.

so what i have found is that after installing dream kernel and messing with the governor settings... along with being connected to wifi. my battery life has improved tremendously. i wiped battery stats this morning after a full charge and didnt notice any change.. then i flashed the kernel and messed with gov. settings... after rebooting ive noticed a huge huge difference.. just my 2 cents for anyone who had battery issues like me

Yesterday I was able to choke out 20 hours while in a 4G area the entire time.
Running RC 1.2, Imoseyon's leanKernel extreme mode (extremely undervolted and OCd to 1.4GHz) and using the InteractiveX governor.
Also, I just happened to reboot and surprisingly it only took away 1% of my battery. Amazing considering whenever I did that on a Sense ROM, I'd experience a battery loss ranging from 7%-10%.

What settings did you land on as best?

cpu is set max to 368 mhz(very low) but i can crank it up if im doing somethign like playing games or downloading and want speed. brightness is at about 15-20 percent. the dream kernel and mr2.0 radio have made a big diff too. the dream kernel made the biggest. usually when id power off or reboot id lose 6-10 percent same as someone else i saw post. now i lose maybe 1 percent which is a huuuuge difference considering you lose 10 percent just because you reboot. also i try to stay on wifi wherever i go. on 3g i def notice it drain quicker, but i am no expert and there are a lot of people on here who by far outexperience and outknowledge me(my new 2 words) so im sure other people have some suggestions

That is strange I am also using CM7 with an extended battery and still have 41% left after 14:56 on battery.
battery use does show
cell standby 31%

android system 19%
wifi 11%
dialer 10%
display 6%

[Q] Battery use question

Hi,
I was questionning my battery life alot lately and I've checked some thread. Yet, everybody seems to have a more "spread out" battery usage. On my phone, battery usage is always like 45% Phone idle and 45% Cell standby.
By battery life seems really random too, I let my phone on standby for a whole night and it went down from 100% to 96%. In the morning, I checked the weather and mails (that's it), then I left it on the table for the whole day and it went down about 50% !
I don't know if something is running in the background or something. Disabling background data helped a bit.
I am running MIUI, but I had the same "issue" with stock ROM and Weapon 2.6. Do I need to change my kernel (it is stock).
Thanks in advance.

I had similar experience until I upgraded from WIND's baseband to the newer T-Mobile one in the T-Mobile update. Now battery life is more reasonable.

Android System Going Rogue

I used to get great battery life with other roms on my galaxy but now since upgrading to the new ucla3 modem my battery dies extremely fast and the android system is always up around 48%! with the phone just sitting ill loose 30% over night when i used to lose 4% or 5% (about 9 hours). Any help would be great i just want to get back that amazing battery life

It definitely sounds like you have a background process running continously and you are not 'deep-sleeping'. Use CPU Spy and check to see if "time-in-state" clock cycles... you should be deep-sleeping 90% of the time during screen-off and know you have shutdown apps you normally use. My experience with UCLA3 modem is very favorable... faster data speeds and better reception coverage. I'm running it with the stock UCLA3 rom and UCLA kernel, and my Android system usage bounces around 1% to 5% CPU usage at any point in time. What rom/kernel are you running? Another suggestion is to use BetterBatteryStats app... great for checking which processes/apps generate wakups, partial wakelocks, and process times.

Ya i know what your talking about and i do have cpu spy and my phone is sleeping quite a bit but it seems that system_server just wakes it up and runs like crazy. im on nexus mod 4 and faux kernel undervolted. anything i could freeze to help with this?

BetterBatteryStats will tell you which processes ars generating wakeups and how many minutes /seconds they're actively using battery

OKay i think i found the problem with my battery drain just running a few trials to see if it really back to normal. will report back

Ya it was weird but i think that the battery drain was the ucla3 update on a rogers phone. not sure but when i went back to rogers radio and quikwiz rom my battery drain issues dissapeared :S oh well thank for your help though

Battery

I could never pump out more than 5h SoT on my opo. Right now I'm getting around 3h before I need to charge it . I'm on stock Cyanogen on 12. I've tried exodus etc and it's all the same :/ My usage isn't even that heavy, I don't play any games at all so I'm sure this is either a rom issue or faulty hardware issue not sure. Is there any setting/rom you guys recommend ? I was thinking about going back to Kitkat but which version has the best battery life ? Thanks and I appreciate any help whatsoever
PS: I disabled the Google services battery drain.

hello dev
i advice you of using this rom
resurrection remix
http://forum.xda-developers.com/oneplus-one/development/rom-resurrection-remix-lp-5-2-0-t2971715
at the moment i'm using it and it's perfect not a single problem mem leak or battery
:good:

Exodus should give you a hell of a battery life. I have heard nothing but good stuff about that ROM. I myself have not used it yet, but I'm planning to.
I get between 4,5 - 6 hours SOT with AK kernel and v1.9 of real_pac's synapse settings. I also use greenify.
Try rooting your phone and add these additional tweaks, your battery life should be much better!

I am rooted and everything. I was on exodus but it was as good as cm12 nightlies :/ Resurrection I have tried too and i only got 3h SoT I'm guessing I'm doing something wrong unfortunately . I'll try to use greenify and I'll report back

I feel you, never got more than around 3 hours of SOT. Brightness is always below 50 percent, I turn off gps when I dont use it, 3G/wifi all day long. Im running exodus as some people said it had amazing battery life, but don't really see a difference. I am rooted with he paid version of greenify + the paid version of amplify, and the power nap xposed module aswell as privacy guard on google play services. Yet I never ever even get close to the 4-9 hours SOT which some people seem to get. I really don't understand it either..

what's the awake time on your Android System or Android OS? I think I'm in the same boat, flashed BlissPop and RenderUber and left it idle with no additional settings or apps installed, then come back to it and find a good chunk of battery life gone. Both roms had Android System using 1hr of awake time.
Then I installed BBS on both roms, found nothing. Google Play Services wake up permission is disabled in Privacy Blocker, haven't installed Greenify or Servicely yet but just wondering why on stock settings there'd be such a heavy drain.
Update:
Just found something interesting. The battery drain now is just pathetic. Powered up my phone, left it idle for 30 seconds and reboot. Bam, 1% of battery life gone. Repeated this 5 times in a row, every time the phone reboots, 1% of battery will drop. It doesn't drop right after, it sometimes drop after the phone idles for about 1~2 minute but that's just insane.

This is completely normal, the boot process is very intensive and consumes more battery than if your phone was just sitting idle, or even being used normally.

For those of you desiring a phone with +6h SoT. Revert back to cm11s and be happy with your SoT. I did two days ago and I have no regrets. Running amplify with greenify simultaneously and I'm getting around 7h SoT.
