I have been using cooked roms on my blackstone for a while now. However, my concern from the beginning has been that these are battery drainer.
I bought it second hand and it had call time of around 60 Hours both IN and OUT.
On 6.1, I used internet very little, but I used to call a lot and listen to music as well for about 2-3 hours a day. In that OS, it used to go up to 3 days.
Then I came into the world of xda-developers and things changed . The battery didn't last for more than a day and a half with the usage I mentioned above. That prompted me to buy new battery.
Since then, On cooked ROM's, I leave my email check for every 15 minutes and weather to an hour. With this usage it hardly last for 2 days on the new battery and I hardly make a call!!
If I make calls, use Opera, it would die in literally half a day.
Can people share their experiences about battery life and cooked roms etc???
I really dont want to go back to 6.1 and I want to keep using 6.5 but the battery issues are really annoying now.
I have used pretty much all the ROM's (Energy, PQD, XannyTech, KWBR, blackStonehenge) with same usage and all of them have yielded same results so it's not ROM based...
Cheers.
I'm using the last ROM that Dutty made for us. With 6 email accounts checking every 15 minutes and an Outlook push account, blue tooth enabled and sometimes an hour of phone use. My phone can't go more than 4 hours on a charge.
Thanks for the heads up. In a few hours I´m getting my own Blackstone with a stock OS. I was already set to change the ROM but with this post will have to delay it a bit until a fix can be found.
Oh, it wasn't that bad at first, it could go a full day. It's just as you add programs and then remove them things get progressively worse. I really need to flash it again to clean it up but I hate having to set everything up again. I'm not a habitual flasher

Luckily, I have found one.
All you need to do is stop using your mobile on 3G.
I have tested it on Energy ROM. With 3G switched on, it lost around 25% of charge in a day on email check for every 15 min and weather for half hour. without any calls.
With 3G switched off and the rest of settings, the charge had only gone down by 12% and that included a couple of calls.
To be honest, I dont think you really need 3G unless you are using internet a lot. Even then, you may switch it on and switch it back off.
I will be trying the new MaxSense UI as well to see whether that helps the battery or not!!
I would of posted this in the development section but it would not allow me but I really like using the RoyalMIUI over CM7 just based on preferences but I just wanted to get a couple of quirks out of the way
1. Does Wi-Fi work on this rom because I use Wi-Fi at the house all the time seeing that HSPA+ speeds do not really reach my living area
2. Is there a good battery saving kernal for RoyalMiui because Miui battery comapred to CM7 battery is meh at the best.
3. Is it possible to download from the market using Wi-Fi I know the development page states an issue about that but is it possible at all?
Help help please! I want to use MIUI but without Wi-Fi, I will be CM7ing like a champ.
Yes wifi works. You can only download apps with wifi is what it says. If you are not on wifi the download will pause and you have to go into your download app that is included and fix it. Wifi crashes the first time you turn it on. Do a battery pull and reboot and you are good to go. As far as battery life, you can underclock using setcpu, but it sounds like you have wifi on all of the time so you arent going to get super amazing battery life anyway.
Alright thanks a lot for your answers, I also could not seem to get the theme manager to import the themes I downloaded and also its would not matter which kernal I used if it the stock kernal or the faux123 under volt kernal?
I thought I would share my recent findings with all of you as it appears battery consumption is a hot topic. First of all I've never had a probem with battery consumption on my DHD, I've always been happy and I'm still happy. This is just an observation.
In my house I have a good wifi signal everywhere except in my bedroom, when I'm lying in bed it can lose connection every now and then, this has not really been a problem until 2.3. It's as simple as this, if I leave wifi on with a fully charged battery next to my bed the next morning there is 10-15% battery left, if I turn wifi off then the next morning there will be 75-85% battery left.
If I'm at work with wifi on all day even though it's not connected to a wifi connection when I go home there is still at least 60% left. Clearly if you leave wifi on connected to a network and the signal drops out every now and then or if the signal is poor expect your battery to be exhausted in no time. Leaving wifi on is not the problem, well in my case it isn't, it all depends on the signal strength of what you connecting to.
Same here . and if you have a good wifi signal the battery life is much much way better than using 3g connection

This is normal behaviour, when wifi is on it will try to reconnect if it loses network, hence in your case it is continually reconnecting to the wifi and draining the battery, if this is a new issue with 2.3 it may be curable by flashing one of the older radios as it may be an issue with the new radio?
same probllem
i have the same problem with my DHD, i have stock rooted rom 2.3.3, and my bettery is draining at an alarming rate, cause it always trying to reconnect to wifi network. but the main prb is that wifi signal is strong, as my laptop has excellent signal, but my phone is strange, sometimes it has full signal, sometimes it drops and completely disconnects from wifi. as i move it arround a bit it reconnects. if i flash an older radio will it resolve this prb? and how do i flash an older radio?

You need to be Radio S-OFF to flash the radio, but if you didn't have the problem previously just try downgrading with one of the RUU's listed here
which will re-flash the older radio which should put you back to before the upgrade, a work round for now is to turn wi-fi off when not actually using it at least for now. BTW this problem doesn't appear to be present in the GB custom rom's so must be some tweak by HTC that has gone awry.
i've searched trough the forum and found some answers. htc made gb drop wifi connection when the signal drops bellow -88dcbl. cusom roms have a drop limit of 101dcbl. i was on stock (only rooted) GB 2.3.3 . I've downloaded kingdoms custom rom v1.7 intalled it but i get blank screen, only wallpaper, and can't get any further. like unlocking screen and getting in to the menu. would you recommend a custom rom that's most stable for DHD? btw my phone is rooted and all OFF. i flashed like... 4 radios all the same problem, so... stock roms are no good.

Do not need to change a custom ROM, and there is a wifi connection fix (decrease the drop threshold) flashable patch zip.
Sorry I have forgotten where is it, but I think you can search and find it among the forum.

CM 7 all the way for me, and if you must have sense ARHD is supposedly very good
Use wifi timeout app so phone can sleep properly, without significant drain.

i use coredroid v7.0 now... and it's the best rom till now, i've tested 80% or custom roms on this forum. it's the most stable and complete rom. i'm sticking to it.
Basically as the title says, my note3 is constantly waking up while on 4g. it doesnt stay in a deep sleep. over the last few days i have done some experimenting erasing apps and turning them off and force stopping. i am pretty sure it is the android system itself not a app i have. i barely have any apps installed. i use maildroid, its setup to push and checks only every 6 hours. i use fleksy for a keyboard. and hoverchat for texting. using nova for a launcher, swipe up for swiping up. pretty simple and clean i keep all of the eye tracking nfc stuff like that off just using it as a simple powerful phone to browse the internet and text.
background. i had the kitkat leak that was posted here in jan i loved it becides everything would stop responding constantly. but the battery life was amazing. so i backtracked went to the 4.3 release then did the official update with the instructions on these boards. immediatly i noticed the battery life was less and the phone wasnt staying alseep so i started the troubleshooting. it has been over a week since the update too i know sometimes new roms take a few days to stablize. but it hasnt.
so what would cause a phone to be constantly being woken up while on 4g only? the pics i included show it. the first about half of the 4 hr 38 minute one part of data i am on 4g only. the long bar of being awake at the start and end of the 4g time is me playing music. the only screenshot the first 1/3 is on 4g only. no music only texting and internet didnt use it much today.
thanks for reading
Grab wakelock detector or Better Battery Stats and let it run for a few hours, then post the log if using BBS - and check the wakelocks, it's possible your signal is fluctuating too much and causing the device to constantly seek. But a wake lock monitor will pretty much tell you exactly what it is.

I was under the impression that wakening detection doesn't work with kit kat unless rooted? I use gsam battery app sometimes and it is basically the kernal it seems.
for most of my time with the phone I am in downtown of a major city with amazing 4g when it is doing it
Update
Tried a wipe reset and it worked great tested off and on WiFi. No drain at all when screen was off. Installed apps slowly and tested and all was good. Then I left the phone on the charger overnight woke up and it was back to the being awake often when on 4g only. I am stumped any new idea's?
hmmm... reminds of of fast dormancy during the S3 days... I wonder if it applies to Note 3

Read up and figured out that its the customer. Xml file It is turned to on I tried editing it but cannot save it because it is protected file I guess. Any other way to save it?
Seems to be the bam_dmux_wakelock I googled it seems to be only when not on WiFi which is my issue. Just gotta figure out the rest
Anyone know how to edit that customer. Xml file? Fast dormacy and the bam_dmux_wakelock seem to go hand in hand. Phone was all over the place today I have 47 minutes of that wakelock with about 6 hours of off WiFi time so it's a decent drain
Hello!
I recently put a new battery into my Nexus 7 2012 3G. Before that I had roughly 17 hours of standby time (I did nothing with it, it just sat in my backpack while I'm at work), now it's exactly the same.
Now I know that in a case like this the battery has to go through a few charging cycles before everything works at 100% capacity but I did that. I put it in on Wednesday last week and I discharged and recharged it four times already without seeing any sort of improvement.
There is an issue with the wakelocks on the Nexus 7 as far as I remember. I did try different Kernels a few months ago but those didn't help and the tablet just sat on my shelf most of the time since then because it was pretty much useless to me because of the low batterylife. Right now it's running with stock ROM and Kernel.
Do you have any suggestions for me? Does the battery need more charging cycles? Are there any new Kernels or ROMs now that completely fix these issues? I really want to use this damn thing again, especially now that I spent 40 bucks on a new battery that I can't return because I threw away the old one! :good:
Thanks in advance!
Mathias
No ideas? You got some change? Come on, help a guy out!
Have you used any apps to try and hunt down any wakelocks? You may have a rogue app or service or something causing problems. Try GSAM battery monitor, it has a great detailed breakdown of this. https://play.google.com/store/apps/details?id=com.gsamlabs.bbm&hl=en .
17 hours of standby definitely sounds low to me. I'm currently running Dirty Unicorn v8.2 (final KK release) with the included kernel and could go for days on standby. I haven't run stock since the initial purchase of the device (almost 2 years ago now), so not sure about what's "normal" on stock, but that sounds low to me either way.
BTW i have a grouper not a tilapia, but that shouldn't make any difference.
Thanks I will try monitoring it with that!
Mine went on for days as well. But then, completely out of the blue and from one day to the next, the standby time went to ****.
I am pretty busy this week, but that just let's me monitor it properly for a few days while it sits on my bag. I will try flashing a different ROM and Kernel this weekend. Thanks!
I have _very_ good experiences with all kinds of SlimRoms. I have the grouper device, but with SlimBean (4.3) I had standby times for up to 10 days with wifi + sync on! My Samsung SIII has SlimBean on it and I have 3 days standby
When discussing battery issues, there's a huge difference between the wifi-only (Grouper) and wifi + 3G (Tilapia)versions of Nexus 7 2012.
I have a Tilapia, and battery life sucks. There's a bug in the OS, ever since day 1. Meaning that switching roms will have minimal effect.
Been there done that.
You should run some kind of battery monitor as PrizmaticSmoke suggested. I use BetterBatteryStats ( http://forum.xda-developers.com/showthread.php?t=1179809 ).
Running the monitor for a day or so, will most likely show that there's a constant wakelock named "baseband xmm power", chewing through your battery in about 24 hours.
Even putting the device in flight mode doesn't kill the wakelock.
I have resorted to manually selecting a 3G network and then removing the sim. I now have stand-by for about 5 days.
Tommmii, even after just 1 hour of monitoring it "baseband xmm power" is already at the top of the wakelocks that suck the battery dry.
I followed your suggestion of selecting a 3G network and removing the SIM card, but that didn't help me. I still lose about 7% during one hour of standby.
@Matttis
not to rub salt into your wound...I'm getting 0.6% / H, when the tablet is in deep sleep.
There is some good news from your monitoring, at least you know there's nothing wrong with the hardware.
The not-so-good part is that there isn't a 100% sure fix for that wakelock, all I have read point towards hit & miss solutions.
I am not willing to experiment with my own tablet, since that might bring back that pesky wakelock which has now been away for 2 months.
Are you actually using the 3G, or would you be a happy camper "downgrading" your Tilapia to a wifi-only Grouper, with the gain of normal batery-life ?
cheers,
Tom.
My boss recently gave me a SIM with a 5GB LTE plan, I might actually be better off if I just use the hotspot of my phone instead
So yeah, I'd be down with that! I do use the 3G feature, but if that means that I will get normal battery life again... You mean flashing the rom of a non-3G N7?

yup, that is the only thing I will experiment with.
Untill then, here is what i remember doing to get rid of the wakelock:
I was in another country with a prepaid burner sim.
I had manually selected the sim's network, in the hopes that this would alleviate the wakelock. It didn't help ofcourse.
I then forgot all about the previous, and travelled back home.
I then removed the foreign sim.
Wakelock gone.
Caveat : the tablet keeps reminding me that the burner sim's network isn't available... duh... I'm in another country AND the sim isn't inserted, yah I kinda figured the network won't be available.
So, what I think _might_ work : insert any sim, manually select that sim's network, disable data in the mobile network settings, eject the sim, power off, power on.
Then keep an eye on the wakelocks...
good luck.
I did exactly that. I manually selected the network, ejected the sim and now the tablet keeps reminding me that the network isn't available.
Still same issue, that didn't help me.
Is it even safely possible to install a rom for a different device? For example, could I just grab the Lollipop factory image for the N7 wifi version and flash that?

Also disable data in Mobile network settings.
Also reboot.
Then watch the wakelock for at least 30 mins, even an hour.

Possible, yes... I want to try it out when I have some time, if only to get that damn Lollipop, which is available for Grouper but not yet for Tilapia.

I went ahead and updated my tilapia to android 5.0.2 for grouper.
Wasn't easy, but it runs stable.
Unfortunately it didn't help with the baseband_xmm_power wakelock
So I took this a step further and did a "fastboot erase radio", I will repost if this helps with the battery drain.
update : no use. Reverted back to 4.4.4 KitKat, and did procedure as outlined a few posts earlier. Standby consumption is now kinda normal at 0.5% / H

I updated to LP 5.0.2 factory,and the wakelock hit me like a brick. What got it gone was Synman's GwT with carcosa kernel.
In fact it is the stock kernel that causes the wakelock,tried with Multirom(which uses patched stock kernel),and wakelock was back,using 7%/hour.
Flashing carcosa-a33-lp-anykernel removed the wakelock.
