So, I've been noticing my phone has been going through a lot more battery recently and part of the reason I believe is due to my Wi-Fi disconnecting and not re-connecting at times. Even if I reenter the password it still won't connect at times. I am forced to turn the antenna completely OFF and then ON again to get it working at times.
I have installed Fresh 0.53 since rooting and haven't noticed any issues with it until recently. The only other thing I have done is tried out different Kernels from ffolkes. Right now I am running the undervolted version os his kernel. Could that have something to do with it or is it unrelated to the Wi-Fi?!
BTW, I have been running the latest versions of the radio and WiMax.
no troubles here when i run flipz or any other rom on wifi
im running baked snacks and get GREAT GREAT battery life
My WiFi is pretty unreliable as well. Im running stock OTA update that was supposed to turn on N. I still get terrible WiFi reception even when very close to router. I get a lot of hang-ups as well when browsing and usually have to refresh a website 5-6 times till it finally kicks in. Either I have a terrible router, or my EVO still has really bad WiFi.
When you format the phone in recovery, you can clear out /data, /cache/, and /system. But what about the other directories at the root of the phone? If any file in there was to go bad, would a stock .tar flashed with ODIN fix it?
Odin goes all the way, even to home base.
Odin restores you back to stock or to a leak that's not been modified in any way shape or form. So, yes it can fix many problems, but you will have to re-root and re-flash Clockwork.
Then this is really weird, I'm not sure if it's hardware related or not. I've always had pretty decent 3G and 4G coverage and great speeds on both. For the past month, download rates have been abysmal at best. Most of the time I get 150kbps down and around 600kbps up on 3G and on 4G I get 100kbps both ways. Wifi works fine. If I turn 4G on and off a few times I go back to 3+ Mbps. 3G is just random and gets fixed if I go into airplane mode a few times.
I've flashed stock tars, modems, and even custom ROMs and all have the same problem. Lately 3G has been more reliably settling around 200 to 300kbps on both ways but it's still a lot less than normal.

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.
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.

happy flashing
Since the first release of oreo I started using the rom as a daily driver, later on paired with a good kernel it had some good perfomance
But after some days of using the rom i started to notice a huge battery drain caused by the Mobile network standby process?
My battery was old (OEM 2014 battery) so i decided to revert back to lineageOS just after a couple of days where I haven't had any issues with that mobile network standby
Now I'm really curious what is causing this issue,drain because I am using the phone on the same settings as on 7.1 nougat, I am living in a country where all networks run on 3G,H+,2G etc. so no 4G if this can be a cause
Changed the network modes many times and tested throughout the days but there was no sucess the drain was still persist, tried updating,downgrading bootloaders swithing modems but again no sucess
If there, in the world of android is any solution, here is the thread to discuss about this issue. :fingers-crossed:
I've wondered this too. I've been running los15 on my g900v , I rooted and boot the first ROM that would work without having or remembering todomuch, I ran the first custom kernal I could find via google, and ran whatever was noted as the latest Verizon modems. its like right off the bat, smooth , consistent battery life and nice. Then the next day I noticed things would crash, my Bt temperamental at best and restarted it just to get by. if I have sync on at home, WiFi off, it just chills , if I turn sync off and drive around town, my battery life gets eaten by the unknown. I pulled some logs to see whats up with my BT but haven't got around to it yet. But my battery too is old (I literally found my s5 in the trash) and I run weird processes and tweak settings all the time just to mess with it, so that could be it to. If I see anything weird I'll let you know.
I'm struggling with this issue for months, since the first port of an Oreo custom ROM (LOS and RR) for the Galaxy A3 Duos (my device) started being developed.
From the beginning I had this problem, and what, since then, puzzles me the most is the fact that only some of us, flashing the same ROM in the same device, experience the issue. Whenever I flash any of those ROMs, even before installing any user apps (or when running in safe mode), the drain is there, which leads me to think that the culprit must be some setting: not an app, because I have none installed; not the ROM itself, because not everybody has this problem.
Unfortunately there seems to be no developers looking into this bug.
For the sake of information, I've observed two things that should help to narrow down the issue; or maybe not.
First, all the devices affected, as far as I've searched, are double SIM.
Second, the Mobile Network Standby (MNS from now on) drain is narrowy connected with the Bluetooth drain (which "also" occurs in Oreo). I've experienced the following: If, after a full charge, I don't switch on Bluetooth at all, then what drains my battery (according to Advanced Battery Usage information) is MNS. However, if I switch bluetooth on -even if only for one minute- then what apparentlyh drains my battery is Bluetooth, at the same speed as MNS did before switching bluetooth on.
Funny enough, the battery use info reports zero minutes activity for both Bluetooth and MNS. But how can a process which runs zero minutes drain 50% of the battery?? I'm afraid that the battery use information isn't reliable. But then that's very bad news, since, in such case, it might well happen that the real juice sucker is neither MNS nor Bluetooth!! We might be dealing with a "ghost" here, since we can't even trust the battery use information provided by the OS.
If someone has something with which to contribute to this research, or any ideas, please comment.
I'm having the same trouble on android 9 betas, even better, my phone gets without signal during those times and there's nothing I could do but rebooting the phone.
How can we help solve this? it looks like it's annoying a lot of people now
