Informal battery test

There are a lot of battery threads out there, but i wanted to try something new. I want to see how much our phones drain in real world situations. So here are the rules:
1. Use your phone normally for ten minutes.
2. Note your battery percent at the beginning and then at the end.
3. Post details about what you did, what ROM you're using, and the percent battery drain.
Hopefully we can compare our experiences and learn something.
I used my phone to surf a few websites, send one text, and use xda app. Started at 80% and ended at 77%. Using rcmix3d at 50% brightness.
I know there are tons of factors that affect battery drain, and I'm not trying to be scientific. I'm just curious how we all compare!

The only way you will get a decent idea is to test with others in your area as it will depend alot in signal strength. I would use more battery if I was bouncing between signals instead of having a steady connection.

Screen-on time is the only thing I ever look at. I've only managed to squeeze about 5h45m, out the sense-based gb ROM I've been using.
The phone does really well in standby on most if not all roms that have been flashed properly, don't have non-rom-related battery hogging app issues, and, as zelendel mentioned, signal issues.
It's this big fat screen that's obviously the biggest battery sucker.

My phone does great in standby as well, but seems to die quick when I'm actually using it. I've never had an issue with the phone dying on me though as I recharge every night. I think i had a little better battery life on miui than I'm getting now.
I know there are many many factors that go into battery performance, I'm just curious what other people actually get when using their phones.

I've gotten accustomed to putting my phone on the charger before bed as well. Mine pretty much will last the entire day... Off charger at ~8-9am, back on it at ~12am.
Averaging about 5 hrs screen on time with usually no voice calls of significant length, WiFi on, gps off, relatively stable signal.
I'm running Inspired Ace 1.0.1, and the 04.11_M2 radio. Seems I was getting a little better with the OTA radio, but signal fluctuated a lot more on that one, than with the 04.11_M2.
Edit: doesn't really use your testing procedure, just more of a general feeling, as there's so many other contributing factors...

10 minutes of on-line gaming (storm8 games) = 10% drain
WiFi off, gps off, mobile data on, screen brightness on auto, stock rom

Holly crap that's a heavy drain. I couldn't possibly use this phone with that type.of battery drain. Thanks to our great dews I managed a little over 7h screen on time. Could only accomplish that by reducing the screen brightness and UC to 768mhz. Stick speed and auto brightness I get about 6-6 1/2 screen on.

My battery will drain about 5% if I even just leave it sitting for ten minutes... I JUST rooted my Inspire and flashed the RCMix3D ROM, and it almost seems worse. Have background data, auto sync, wifi, gps, bluetooth, all that stuff shut off, too. I love this rom, but really want to find one that improves battery life!

You probably got a bad flash, or have something else running, as I mentioned in your recent thread.
Did you full wipe prior to flashing?
Try out gingerbeast, if you still have battery issues with that, after properly wiping prior to flashing of course, then it's hardware, as that ROM has produced some record-breaking battery life performance.

Mine has twice decided to randomly have days where it just drains like crazy. The battery is a lot warmer and just dies out in like 6 hours with very minimal usage. the majority of the time my battery is great but the last 2 days and then about a month ago it did this. No reason for it either, I have made no changes on my device.
Anybody seen this?

Yeah I did a full wipe before flashing. I'll be sure and try that out tomorrow, I really hope it helps. If the issue is hardware, should I contact HTC? After I believe you said my phone should still be under warranty, I called them, and indeed it is. The rep I had before must have been new or something. Thanks

From a full charge, on TPGB with wifi, gps, and sync on, and everything refreshed 3-4hrs, I lasted about 8 hours. I was using super accurate gps for 20 minute intervals or so, but it lasted the day I'd say. Some occasional web browsing.
Lucky for me my head unit on my car has a usb port. For this whole trip I left it off though.

What is best ROM for battery life?

Hello,
Anybody who flashed tons of different ROMs, can you comment which ROM provided best battery life for you. I'm not looking for absolute numbers but comparison of different ROMs as far as battery drain is corncerned for the same user.

Is less about the rom and more about the kernel and u/v u/c in my opinion...radio can have an effect too
Currently I am on coca-cola with dag's .3 kernel using the Gideon battery saver script.
I like using that on the quickwiz rom too

Ive been flashing a lot of roms the past week. I'm currently using [ROM][UXKJ2]Buoyancy v1.3.0||Rogers/AT&T||[1/25/12]
Deff the best so far. Very quick and it's been 11.5 hours and I'm at 57%! Kudos to jomeister15 and his team!

You are on ATT network and in LTE enabled zone?

Nexus had the best for me. I also hear Buoyancy is great as well. Sky ice cream sandwhich is what im running now but i charge my phone a lot. An update should be coming soon for battery life fixes on it though.

radio on or off?
I've been running TPC v3 on my 727R for about 2 weeks, with his oc startup script. My battery life wasn't so great until I decided to start turning off data while not using it. Made my battery life go through the roof.
From full charged, I was still at 69% 20 hours later. Mind you, I wasn't using it that much but even still.
Which leads me to wonder: are people actually turning radio off when not in use? Because with it on, I can't get anywhere near those numbers.

What will you be missing if background sync is off while screen is out? everything relying on push notifications will stop working or will be there some other noticeable changes?

I use skyICS and I get pretty good battery.
The pic is of my first battery cycle on skyICS, with pretty decent usage on it. The red little bit at the end is me trying to kill the battery. I had wifi on, data, sync, flashlight, and ran quadrant standard non-stop for about a 30 minutes.
I think a lot of it will depend on how you use the phone. As mentioned above, simply turning off data saves you a lot of power. Going into airplane mode saves even more. I lose almost nothing in airplane mode (I put it on at night). You can get an app in the market that will auto turn off settings for you if you're too lazy to do it yourself.

Improving Battery Life?

I'm using the Virtuous Inquisition 4.0.2 ROM and my battery life, while better than what it was pre rooting, is still not that great. When I'm outside my house and using 3G, my battery drops by about 8-10% per hour. This is quite poor compared to some of the battery usage I see on this forum with various people posting their screenshots. What exactly can I do to improve battery life?

They're are many little tricks you can do to preserve battery but one thing that actually helped me the most was switching out my stock battery for a long lasting battery. Most of us have done this this is why your seeing the different results. I personally use Anker battery. It's given me a lot more battery time than stock ever had! This is really the best way to go.As for the tricks you can check your settings and turn down or off some of the things that are draining battery like led, turn down back light , keyboard feed back, check your sync and only sync what's necessary, make sure no logging is taking place , ect. Just look for what you might think is draining battery and adjust the settings accordingly. I hope this helps you out. It had helped me. Best wishes.

Well I am using the Anker battery for a pretty long time now and I still don't anywhere close to the battery performance that most others here seem to get. What 3.32 based kernel would you suggest which would best help save battery?

I like bricked ,but try a few out and see what you think. Bricked has proven to give me the best battery life personally. Best wishes.

What battery u using

Kernels doesn't seem to help if i put brightness to 50% on virtuous rom i can get up to 4 hour screen on time whit anker battery ..
Sent From My Sexy Sensation.

you can try using juice defender, changing cell type to 2G or GSM (PRL) in 4636 menu, switch off synchro, set conservative governor or make own cpu seting (disable second core for ex.) Hypernonsense is good batterry saving aosp rom. im using it with stock kernel

HUGE battery drain with Viper ROM

Hey,
I just switched to the new Viper ROM for the DHD.
It works rockstable and very smooth, but the drain is immense.
The telephone app uses 49% power. How is that possible?
Any ideas on how to fix this bug?
Greetings from cologne.
PS: sry for posting this here. I'm still not unlocked for the developers forums

I did change my rom to viper 2 weeks ago and change also to lupus v5 kernel, and i have less battery drain than before, also maybe it s a question of Kernel...

Hi there!
Well, I have been using Viper V4 ROM for a while now and on stock Kernel [Viper V4.5 available here if you want http://forum.xda-developers.com/showthread.php?t=2128642] and in the first couple days or so I did notice a massive drain in battery life however this drain did become much better when the ROM "settled".
The second point is that I don't permanently leave my 3G, network data, wifi, etc, always on but only on a "use as you need" basis. This does not only extend your battery time duration obviously but also your eventual battery life. You might want to think long term and start to opt this way also.
Thirdly Viper ROM comes with various tweaks and one of them is for battery economy [you can find that under \menu\settings\power saver] where you can actually program 3 different modes with different times and specs at your own wish.
Fourthly I know of a great personal tweak that really works on Android phones but I really did not have to do it on Viper because as mentioned before the battery life for me is good enough [one charge=over 48 hours!] but I'll teach you nevertheless:
When your battery gets to 3% use the app Root Explorer and go to: \data\system\batterystats.bin and delete this file [batterystats.bin]. Go ahead...no fear...it won't damage your phone!
Then turn on your 3G, network data/traffic, wifi, screenlight to maximum [you must be quick before your phone turns off!!!!!]
Then put the charger in your phone and reboot with it plugged in charging and phone ON...confirm that your 3G, network data, etc is still on.
Leave all of them on until finish 100% charge...remember that will take more time to charge...after charge turn 3G, network data, wifi OFF and use as you need basis or as you would normally use but avoid always leaving them on 24 hours.
When your battery reaches 3% or even 5% this time, do the above again but DON'T EVER DELETE BATTERYSTATS.BIN AGAIN!!!!!
Do the whole process 4 or 5 times and you will notice INCREDIBLE change in battery life from there on. After these 4/5 times you can stop doing the process.
NEVER! Charge your phone at any point in the battery indicator above than 5%
I hope this helps you...please let me know.
Oh and don't forget to click on THANKS.

Thanks alot for your answers!
I've tried to calibrate the battery with your described method, but that doesn't change the high power consumption by the telephon app...
Switching the Kernel looks like a good idea to try. I will do that tomorrow and post my results here
greetings!

Hi there mate!
Yeah sure, that would be my choice also but I'm still stuck with stock kernel due to locked bootloader from SIM block...until then...
See ya later mate.

Rom based around battery?

Hey im looking for a rom that is great on battery. I just got up an hour ago and my battery is already at 90%. I feel like its going down too fast. Im using Purity rom with greenify.

Hi,
Better is to try by yourself, battery life is mainly based on your own settings and usage. If you have some rogue apps, bad network reception and your brightness at 100% (it's an example but I think you see what I mean).... Whatever the rom it will be the same thing.
1 hour... 90%... all depends of what kind of wackelocks you have, synchro, etc...
There is a ton of thread about battery life, take a look in them for help.
And: http://forum.xda-developers.com/showthread.php?t=2477889.

And also purity is awesome on battery life when I was using it... There are way too many factors to consider when talking battery life.

Stock Rom works very well. But it really does depend on the processes you run and the apps you install. Thus "best" becomes a relative term. If you have very bad network reception I'd recommend installing a kernel like Franco kernel. It stopped draining my battery even in areas of bad reception.

As it has been mentioned, battery life depends just as much on you and your usage / location / etc / etc.
Something tells me though that the roms that have in their title: Battery Saver Script might be something that focuses on what you are looking for. Just a shot in the dark...
http://forum.xda-developers.com/showthread.php?t=2611759
http://forum.xda-developers.com/showthread.php?t=2619357
One of those was literally on the front page of roms listed in Development.

I use omni rom with franco kernel r31 and I get 3 hours screen time with about 13 hours battery life most days. I use the internet a lot and text all day.

There are too many factors that affect battery life but also these threads are not allowed on XDA, as pointed out above. Try some out yourself and see which best suits your needs.
