Is your wifi staying on all the time, i.e. when it goes to sleep?

no def careful about that

Do you actually turn wifi off before putting it to sleep? I do, and have no complaints.

yes very careful about eh wifi thought there might be something else i can do

1 reinstall the ROM or
2 install a different ROM (stock or other).
I had no problems on CM7 with battery life.

Mine only seems to drop a few % a day when not used.

i think i got triple battery life after i installed 'setcpu' app.
.
hmm, but you say it was happy before cm7 and then it changed... that's not the norm. i vote for re-install ( are we voting ? )
when you installed, did you do the ( critical ) steps of clearing the dalvik and cache ?

i vote reinstall and to have the kardashians put on some island

Fascinate CM7 standby battery drain

So i have a verizon fascinate and am currently running cm7. (first tried the stable release but niw a nightly). Im eeally liking cm, but since i got it my battery life is garbage. Basically the drain seems to come from either the android os sercice or cell standby. Whenever i leave my phone inactive for a while, when i wake it up the battery has dropped a lot and tge phone is very warm. I have been modding this phone for a while, but im no android programmer. Purely based on the forum searchi. G ive done on the issue, it seemsblike cm7 has an issue with my modem or radio.
Extra info: my 3g/2g signals seem fine (always 0% time without signal). Wifi connectivity seems fine. Im also running glitch's kernal altho the problem has persisted with and without it (i did do a kernel cleaning first). I used the "go from anything to jb vanilla" guide cuz i was having issues switching to mtd at first (sry dont have a link rite now but it was on xda) . I get occassional force closes, but not really a problem. When i did a titanium back up, the very first time i flashed cm7 i Did restore system settings, but i did not do that every time since then. Ive done a fresh flash of the stable mod around 3 times trying different stuff, but this one is niggtly as i said, and each has had this issue.
If looked around a lot, and wgile this seems common, no one has posted a consistent solution or explanation to the problem, so thats what im looking for.

You could flash jt's vanilla gb rom. That has good battery life.

I have had the standby battery drain on every CM7 version and Kernel tried so far including 7.1 stable,7.0 nightlies,JT's Vanilla,and PoolParty. It's even worse if I shut phone down and don't plug in. It will drop 50 to 75% overnight with phone not on?
Has done it with undervolting,overclocking,and voltage control not even installed. This is first time I have seen others having similiar issues.
I think this is a known issue for all MTD roms on the fascinate, if I'm not mistaken.

I lose only 5% to 10% overnight on CM7 never really notice how much on MIUI cause I never ran it long enough. I guess every phone would behave differently for MTD's or maybe you have an app or mulitple ones that refreshes frequently(Fancy Widget comes to mind).
Well that really sucks, because i do enjoy cm7. But this also means if i go back to a touchwiz configuration like stock dl09 i shouldnt have these issues right?
But before that, has anyone who had these issues tried anything (ie kernels or maybe standby mode power conservation setting, etc... ) that have at least noticeably improved your battery life? Right now mines pretty unbearable (im talking 8hrs while on but totally inactive), but if i can get it up a little i might b able to manage.

I am also experiencing poor battery life. I just flashed 7.1.0 yesterday and absolutely love it. Was using com rom for a few months, but a friend said to try out cwm 7. I used to get about 6 - 8 hours of Pandora while at work and today I only got about 4 before my phone shut off. I'm going to try completely killing battery and charge with phone off tonight an see if it's any better tomorrow.
Any other suggestions? I'm not a noob when it comes to custom roms and flashing (I used to flash the **** out of my G1) but there may have been something I over looked when switching to cwm7. I wiped everything a few times before flashing including battery stats and dalvic.
My battery life is actually really good. Running latest nighty, undervolted -75 across the board,stock kernel, and no overclocking.
Just can't figure why I lose 50-75% of battery overnight when phone is shut down and not charging?
I have the same issue with CM7.1, turning phone of at 80% battery at night to find it at 25% at morning
Is there knows solution?

Atrix random reboots and screen not turning back on

Hi all,
I'm wondering if anyone can help me....I'm getting kind of desperate here! Basically my Atrix keeps randomly rebooting or getting stuck with the screen off (requiring a batter pull) . This happens about 10-20 times a day (my Atrix is far too unreliable right now to use as a daily). This seems to ONLY happen when on network (ie 2g/3g/hspa) and doesn't seem to happen on wifi. I can leave it on all night and day at home on wifi happily with no trouble but as soon as I go to work and leave it on network, the trouble starts. Its weird cause if the phone is doing something with the screen off (playing and streaming music over Bluetooth for example) it won't have any problems. Its only once I leave it at rest on the network that it turns into the most unreliable handset ever.
At first I thought it may be the neutrino rom I was running but I've since been using jokersax's amazing ics builds and the same problem persists. I did a full clean (format /data & /system plus cache and factory wipe ) and loaded on the latest beta build this morning, left it clean with zero apps except google (and xda!) and within an hour of getting to work the problem came back.
I am fully boot loader and network unlocked.
Please, if anyone has any idea I would be really grateful. I am tearing my hair out!

It is happening with me too, but, I dont realize it on happen on mobile data connection
Since i flashed beta 0.1.0 2d of Jokersax's ICS and come out of home

Why not try a more stable ROM first and see if you get reboots.You do realize some phones just cannot handle unstable roms like the cm9 builds even though they are great for some ppl it just doesn't workout also maybe you are using an oc kernel that your phone cannot handle.I would check both things first.
Try some a bit more stable.
cm7 ba2ft
wetdream
darkside
gingermod
If you get the same with those then maybe fastboot wipe and stuff like that so you can clear everything out
EDIT: flash a radio too

Hey,
Thanks, I'm going to try Gingerblur tonight... I had ruled that out as I have used darkside/gingerblur before and apart from the occasional reboot they were OK. The reboot was OK really, I know its a known issue with this model even with unrooted handsets, as long as its occasional and clean boots back to system again it doesn't really matter as I don't pin lock my sim (currently my problems are either a reboot every three minutes as soon as I switch the screen off... or, more commonly, the dead screen, needing that battery pull) .
I *suspect* that it may be the radio, but really need some solid advice on this because a couple of years ago I completely bricked my G1 by flashing the wrong radio and vowed never to touch radios again if I didn't have to....I am naturally very hesitant about radio flashing from that episode. Can anyone give me some decent advice on which radios i should be looking at for an unlocked ( but formerly Orange UK) Atrix? One very nervous owner here!
The other weird thing is that is perfectly fine when on a power source.

Hang on, I'm not making sense here, maybe it is these advanced ROMs, I was just surprised that neutrino (a cm7 based rom) also produced these reboot problems. Anyway, any advice on radios would be appreciated

As long as you flash atrix radios only you should be okay. I flashed just about every applicable radio on my brother's captivate and never bricked it.
I agree with you and previous posters, it sounds like a radio issue for sure.

I have the same problem with my Atrix running cm7 ba2ft. Sometimes it does not respond when you try to unlock, and I need to take out the battery to turn it on again. I bought the phone couple of weeks ago.
another thing to look at would be the battery my friend had similar problems with his nexus and tryed Roms and radios I bought him a new battery as a joke and the joke ended up on me cause he hasn't had the problem since let me know if this helped you aswell

Same problem here. Very aggravating.
I am having the same problem. And I am 100% stock with no mods. I just installed OTA 2.3.6 so I am waiting to see if that helped.
Yeah, I'm really worried this is a hardware problem - I've been quiet these past couple of days testing the brand new GB radio and when that still had errors i then also tried the European one - the problem still persists. I have now downloaded every Atrix radio under the sun now so may try a few more...
This is quite frustrating as a) I really want to enjoy ICS as it really is a step up from previous versions of Android and b) I no longer have the option of selling this in its current state.
I'm also going to try a new battery as WikidClown suggested above, can't harm....I can pick up one on Amazon for less than a tenner.
One thing is for sure, I don't think I will be buying Moto hardware again!

i baught my atrix used. everything was stock. still had multiple reboots and battery pulls daily. on cm9 they seem to happen less. and the battery pull only happened once. but i know the issue must still be there. might try my wifes battery. her atrix has rebooted maybe 5 times ever. 3 since this last official update (she is still lock stock and 2 smoking barrels)
OK, trying a new battery is my last hope...I did a fastboot wipe this morning and for an hour and a half it was all going so well...but then the reboot happened.
I'm getting a bit fed up with this pos hardware...I can't even sell this thing in this state.
Sent from my MB860 using XDA App
Anyone have any other experiences? I have confirmed that it isn't the battery...I bought a new batter and within 45 minutes it has rebooted once and done the screen off thing where it needs a battery pull. Complete crap.
One thing to note is that it does seem to get very warm on the back, although the internals ( behind the battery) don't seem so bad. Is there any way to keep the temp down aside from underclocking? All my roms have always been under clocked so I know that doesn't make any difference.
The other thing I might try is to use something like Noled so the phone isn't completely idle. Might drain the battery a bit unnecessarily though....why couldn't Moto have put in an amoled screen?
Anyway, will report back once I've tried it.

I used to get tons of random reboots and then I was told to get the app called "Wake My Android Pro". Settings -> Test Activity -> Auto Startup, and Stop Activity checked. Weird settings, I know, technically with stop activity checked it doesn't do anything, but ever since then I don't experience random reboots. This was a few months ago when I was on just CM7. I've always installed this app when I get a new rom and I've tried Neutrino, Darkside, Alien, Aura, CM7, Wet Dream, and currently on joker's CM9 beta 1 build and RARELY experience random reboots. It went from once an hour to once a month now. I'm also on the .36p radio if that helps.

Cheers, have downloaded and will report back. The most annoying thing about troubleshooting a problem like this is that there is no immediate 'it worked or 'it didn't work' ....it's just a waiting game! Thanks a lot though, really hope it does work (and thanks for replying, was starting to feel like I was answering threads to myself!). I have .36 radio installed already (I think, will check...it's the Brazilian one isn't it?) .
Just to check then...you have all the check boxes in wake my android ticked?

[Q] Help, new to this

Hi, I downloaded and installed XWLPY NeatRom Lite v3.5 (18th October 2012)a couple of days ago and now my battery is draining extremely fast. I tried a couple of battery managers and nothing seems to work.
Anyone with any ideas on what I can do to remedy this? Plus I can't see the update section in my settings, is it removed with this software?

The ROM doesnt have an update because the devs have removed it because you just flash an update. As for the battery drain give it a few more days if the problem persists try another ROM. If it still persists after that try recalibrating the battery or resetting the fuel gauge chip.
Hope this helps

Hi,
NeatROM 3.5 is one of the best ROMs from battery backup perspective. And I can say that because I am using it since 3.5 came out and have never had any issues.
For a better battery life, follow the steps from the link,
http://forum.xda-developers.com/showpost.php?p=33045733&postcount=8776
Please note that the instructions are prepared to get the most out of your battery. Even if you follow the few ones that you are comfortable with, you will surely see some improvement.
Please press Thanks if this has helped you.

Its simple mate. Just download an app and hit a button.
Usually battery drain is due to one of two things.
-Phone not going into deep sleep
-Wakelocks.
Download an app like CPU spy. you can use it to see whether or not your phone is going into deep sleep like it should. Also, use better battery stats to look for wakelocks. Download the app from HERE , let it run for one battery cycle and then check for wakelocks. If you dont know what those are, spend some time reading that thread.
But if you want to hold off for a couple of days, you can do that. It does take some time for a phone battery to settle when a new rom/kernel has been installed, after which battery life tends to improve.

Thank you very much for your help mate. I've tried a couple of battery managers off play (juice defender and another one). Right now kind of regretting this download, everything seems to be going wrong;
1. battery is draining @ 15% in 20 mins ( I only bought the battery last week after having the phone unlocked).
2. there's a lot of lag
3. screens keep freezing and
4. keep losing reception and constantly having to restart phone.
I only downloaded this cause after unlocking my phone it failed to update. Is there any other that I can download that works well with SGS2?
There's no dearth of ROMs for the i9100 dude. Try a couple out and see if those help. If its stability you're after, maybe use an ICS Rom rather than JB.
15% in 20 mins isn't normal even for a first day..you sure it isn't a faulty battery right? Was it giving decent life before you switched to this ROM?
Try downloading a calibration app and see what the voltage is when it says its charged 100%. Should be around 4100-4200 mAh.
As for the lags and freezes, did you wipe data, cache etc before you installed this Rom?
Sent from my GT-I9100 using xda app-developers app
I had cleared the cache in settings before installing. Like I said, my first time doing this. Seemed straight forward at the time.
Since my phone is unlocked, will it return to ics4.0.3 which is what I had before?
Battery calibration app is showing 4161mv.
Will a factory reset help?
Thanks for all the help, site can be a bit confusing sometimes lol.

Cache from settings? No. I meant clearing cache from the CWM recovery menu. If you installed the ROM via CWM, that is.
If you did, I'd suggest reinstalling it again via cwm this time clearing data, cache and dalvik cache.
Ok..I just realised I totally assumed you'd installed it using CWM. Not sure if you did.
You can return to 4.0.3 if you want. Download stock firmware from sammobile.com and install it via Odin. I'm sure there's a guide on how to do that somewhere on this site.
Just noticed someone posted instructions on maximising battery. Did you use those? It could explain the freezes if they started after that. Some phones just can't handle undervolting etc.

Morning, I downloaded some battery managers and seems to be working better and faster. Battery discharged 27% in 5 hours.
Will see how it goes over the next couple of days.

Thanks and gave a great day!
Sent from my GT-I9100 using xda app-developers app
Haha that's a lotta apps just to save battery. As long as it helps eh? 27% in 5 hours is pretty acceptable for moderately heavy use. Depends on your signal strength and whether you're using data or on WiFi etc.

Holy hell Batman at the Battery Drain!

Is anyone else getting Android OS around 50-60% battery use?
I have tried every ROM included going back to stock. I have ran the phone with nothing but Stock and no apps installed for a day and still get the same drain so I can only assume its a kernel issue.
I am not familiar with LG products in the slightest, but I had a yellow screen of death the other day...something I have never seen in my years with samsung android products. Anyone have any idea what this is maybe it is pointing to a hardware issue?
LG made a great phone, but I don't think I will keep it much longer. Locked boot loaders, no sources, and history of terrible updates have me regretting purchasing this phone. I tried my hand at building a working jb release when I first got the phone and it is going to take a skill set I do not have and I hate waiting on a company to do what they've never done in the past..

Easy, brother. I have only had one of my apps/utilities run higher than AndroidOS ever on this phone; however, that said, I think there is a problem with the way it's being calculated. I'm getting really good battery life with good sleep and still AndroidOS shows the highest by far. I know that's abnormal for it to be so high and still get good battery life, but it is what it is.
Edit: you've installed the fast dormancy toggle, right? As for the yellow screen, I've seen it once in my two months with the phone, just rebooted and carried on. Forgot what they said it was...but it is here in this forum somewhere.
Sent from my LG-E970 using xda app-developers app
I was just about to post something similar. Andriod OS being high kind of makes sense if nothing else is using the battery, although you would expect that number to fall significantly with increased screen on time and heavy app usage, which it doesn't ever seem to.
I've been having horrible battery drain lately. I'm currently traveling for business, and just use my OG for web surfing and stuff when I'm in my hotel. I leave the phone in airplane mode, with WiFi on. About two weeks ago, when I was on The Base 0.4 in that same configuration, my battery would drain maybe 1% an hour while I was sleeping.
Recently I've been on The Base 0.7.3, and my battery drains over 5% an hour while I'm sleeping. This means no screen on, no apps running, and even turning WiFi off! How does it use that much battery when it's not doing anything? Now, I'm not entirely sure what kernel I'm running. The first time I installed The Base 0.7.3 I used sk8's kernel. After getting poor battery life, I reflashed 0.7 and 0.7.3, this time choosing the freegee kernel. I'm not actually sure if the kernel changed though.
Anyway, I think I'll post again tomorrow with some screenshots from Better Battery Stats+ and CPU Spy.
I'm wondering if this recent botched update had the battery fixes we need. Hopefully they'll re-release it soon.

I leave the phone in airplane mode, with WiFi on. About two weeks ago, when I was on The Base 0.4 in that same configuration, my battery would drain maybe 1% an hour while I was sleeping.
Recently I've been on The Base 0.7.3, and my battery drains over 5% an hour while I'm sleeping. This means no screen on, no apps running, and even turning WiFi off! How does it use that much battery when it's not doing anything? Now, I'm not entirely sure what kernel I'm running. The first time I installed The Base 0.7.3 I used sk8's kernel. After getting poor battery life, I reflashed 0.7 and 0.7.3, this time choosing the freegee kernel. I'm not actually sure if the kernel changed though.
Anyway, I think I'll post again tomorrow with some screenshots from BatteryStats+ and CPU Spy.
I'm wondering if this recent botched update had the battery fixes we need. Hopefully they'll re-release it soon.

When I would get bad drain, which has happened several times, I could narrow it down to a couple things in order to solve the problem.
In my case it would always happen after installing Google+. Uninstall and reboot would usually fix the issue. If I got drain on a fresh install without g+ installed, I found that if I installed the 2.2 kernel separately as a stand alone zip, that would fix it. Don't know why but it may work for you too.
I don't have screen shots, but today I recharged at 38% after 3:10 of phone use and 1:55 screen on time and about 15 hours off charger. That's with Wi-Fi on the whole time and Bluetooth for about 9 hours. I have my work exchange account on active sync with push notifications. Facebook and Twitterer to 4 hour intervals. I'm underclocked to 1350 and using powersave gov with deadline.

Believe you are correct. There were issues on the Samsung Infuse and even the international SGS3 for a while... it was referred to as 'memory leak.' Has been worked out by devs on XDA. You can put memory leak in the XDA search above... it's above my pay grade.
Edit: It's great to see another RD here... hope you will reconsider keeping the phone and stay !!

Thanks for pointing me in the right direction. I have Google+ uninstalled, but part of me thinks Google Now may be partially the culprit (although why that would be the case with all radios off, I don't know).
I'll try a fresh install of the 2.2 kernel and see if that helps. Thanks.
I can't speak for anyone else but FDT did wonders for my battery life. I was only able to go about 12 hours prior to disabling FD.

This is good for sure... it's just that compared to other phones, Android OS and Android System should not be that high.

^^^ This is indeed worth considering.... I think the question then becomes why is it consistent among the 3 roms we are using? Maybe when JB source is out and something is built from source all will be good.

I would be less inclined to believe it is a faulty measure if we had a different ROM not built off stock (AOKP/CM10) that could produce different values. However, I seriously doubt anything built into either of the two custom ROM's is geared toward normalizing that reading. That's why they are both the same as the stock AndroidOS percentages. Jivy is probably right that it's a kernel issue. With the size battery we have, imagine the potential if it is a true reading (androidOS out-of-control) and we can get it under control down the road. We're talking double the current best battery life you've ever had on this phone at the very least.

Get BetterBatteryStats, select Since unplugged and Alarms to see what is waking the device (making it not go into a deep sleep). eBay was a big culprit for me.
The wakelock that keeps the phone awake during background data transfer (screen off) lasts 6 seconds (I am guessing it does it in multiples of 6s) regardless of how long the sync takes. Everytime email, facebook, gmail, drive, picasa, twitter, g+, google maps, ebay, calendar, contacts.. whatever wakes the phone to check something, it will be a minimum of 6 seconds.. This adds up over the course of the day and it is counted in the Android OS. Shut down syncs you don't absolutely want/need and this number will go down. All phones with the Snapdragon S4 Pro has it, especially the Nexus4. It seems they've done some kernel work to fix/reduce it but I havent really looked into it since I don't have that phone. I've seen complaints in the Droid DNA forum as well.

This. EBay for me too. BetterBatteryStats is your friend.
Anyone else experiencing scrolling lag or delay. Clearing cache and wiping dalvik fixes it but the issue returns after about two days.

[Q] Battery Help needed - Moving form the Beanstown Post

Coming from http://forum.xda-developers.com/showthread.php?t=2032447&page=835
I have been having battery drain issues on beans town ROM ever since i loaded Build 7 (currently on build 10). 20% battery drop in 4 hours of sleep (even with the Wifi and 4G off)
I am trying to determine what is causing it. I have screen capture of the warnings below and the alarm screen is blank in Better Battery Stats- The other 2 attachments are from yesterday
I have Google location off.
I am strongly considering just going back to stock at this point- the drain is not acceptable.
Stock got 2 days with normal use (I have responded to other posts where they say it depends etc etc- understand that but- big but- normal use on stock for 24 hours took it down to maybe 55%- i can drop to 55% in 8-9 hours with the phone unused in sleep on this ROM )
You may not want to come off with attitude of you want people to help. It sounds like that in op.
Two things I notice. First your wifi is on in those shots. Service to be honest nothing seems abnormal

Except you used your phone so it wasn't just sitting. How long are those phone calls for? By the way are you in a bad signal area?

Hi- no attitude but I am wondering if I am the only one seeing this or not. I realize this is "for free" support and people help here because they love the technology or just want to help- so i appreciate that- sorry if I gave that impression.
I live in a heavy populated area in Atlanta with strong signal, even in the house (at least 3bars). the calls i think were 1 min 47 seconds if i recall correctly. regarding Wifi- i may have turned it back on right before the screen shot as I saw the battery still going down at pretty much the same rate)
I am wondering if it is an inherent HW problem with either the battery or something with the air interface- motherboard
Based on the screenshots, your phone was on for just under 5 hours, and wifi was on for 4.5 hrs of that time, so 90% of the time. If wifi was on, but not connected and was scanning, I could see that causing significant drain. Also, do you have any theme installed? Any other changes made to the ROM itself?

I have wifi set to turn off when phone is asleep- when i wake the phone, I see that wifi is off and it will reconnect to the AP at my house.
I lost some train of thought when switching threads but i believe Wifi was off (I know it shows on in the screenshot)- which makes me think something is amiss here in HW. that is why i am pretty sure i turned off all interfaces last night and left them off.
I also have power saving mode on for the phone.
The phone is at 51% currently- I will place it back on charger to take it to 100% then turn off all air interfaces and see what happens
That a good plan?
Go into your apps and clear the data on wifi share... why if your phone is sleeping it needs to be using wifi 58 percent of the time? ...this tells me an app is waking the phone...so look and see what is causing the most wake locks...once you find the app causing the most wake locks... Delete it and reinstall... Then go into the settings of that app and set your sync to a reasonable interval... Last of all go have three hours of coffee at star bucks and use their wifi to check and see if your modem is causing the problem...
Other solutions....use sd maid and clean all system, apps, and ghost files..
Do a davlik and cache wipe in recovery
And last effort do a davlik and cache wipe with a reinstall of your rom...
Keep in mind after each step your phone will use excessive battery because it will be adding files and moving things around... SO patience is important when cleaning and installing because it may take a few full discharges and charges before it settles down and gives you a good idea of what your battery life will be like
Also I am wondering... Two days with your phone on stock... But a whole day while rom'd...i am wondering...did you play with you phone as much when stock?... I know I didn't... :thumbup::thumbup::thumbup:

Quick thing have you wiped both caches and fixed permissions? Sometimes that will do wonders when the phone is acting up.
Also I was just pointing out it sounded like you were giving attitude. I actually figured you were just frustrated at this point. I've seen the posts in beans thread. So I wanted you to clarify before getting flamed.
The community will get this fixed. Beans had great battery life when I ran it before switching back to Eclipse so it's something going in on your phone.

I have a great idea, get rid of the task killer or set it to manual. Task killers will destroy your battery life if set to auto kill.
Also do you have an SD card? Take it out for a few hours and see what the battery life is like. If it gets better then copy everything to your computer and format the card and copy it back.

Thanks for the pointers. I will respond to all the questions ( I think) here
I have done this previously (did not help)- suggested also by another response
1. Wiped Davlik cache and fix permissions
2. upgraded to 2.4.3 TWRP from 2.3.2
3. Wiped Davlik cache and fix permissions again (twice on 2.4.3)
4. I have not done anything with regard to the SD card- I will look at that after looking at the Wifi closer
In Wifi- I can see wifi direct share process in all in one toolbox but do not see an app- I would assume wifi is part of the kernel. I am not sure how to clean the cache or delete/reinstall the wifi direct share unless it's a .apk hanging around outside the /system/apps folder-update- i found it- cleared data and will let rthe phone run for a few hours
I did not play around with the Stock build from VZW- it was 2 days right out of the box with "normal" call use.
The reason I think it's a HW issue is that this si a replacement phone for the one the girlfriend cracked after having a new one from VZW for 20 days. That was the phone that could go 2 days on stock unaltered VZW. This I am sure is a refurb from the repair depot. I placed Beanstown 7 on it right after I got it (I practiced unlocking on the cracked original phone)

Thanks for suggestion- Advanced Task Killer is set to disable (no auto kill already). I will look at SD card once i look at Wifi
Update this morning
Girlfriend used phone for maybe 30 minutes or so this morning. I have attached the better battery Stats
I noticed that Wifi is on and running most of the time- even though it is set to turn off when phone sleeps. Is the next step then to Starbucks or can I simply turn Wifi off
When i loaded Build10, I followed the instructions.
1. Wipe Data- I did not format data
2. Factory reset
3. Wipe Davlivk Cache and cache
4. Installed ROM
Manually turn off wifi. Also do you have another battery monitor app besides bbs? Ultimately though your phone is going into deep sleep so I'm not sure what going on

Ok will do- I do not have another app but happy to buy/try another one. I do have another battery as well.
She's out with the phone for a bit- do I need to fully charge and then turn off wifi or can I reset the battery stats (assume I can) and just turn off wifi?

Just my two cents...i always use titanium or romtoolbox to delete maps as google maps was draining my battery.. Also kernel can make a difference..location servives and maps keeps wifi searching and almost constantly in use and if services on and wifi off they will keep trying to reconnect. I feel running maps is a battery waste. If i need directions i will google address. Call me old fashioned but ill read,read,understand the set my path..i prefer battery life
I get almost 48 hrs out of battery with 5hrs screen...only 24 with closer to 9hrs sscreen on, was half that with locations and maps running
