[Q] Vivid not coming out of 4G idle - HTC Vivid, Raider, Velocity

I've been noticing this problem with my vivid since I bought it 4 days ago. If I havent used it in a hour or so and I try to connect to any Internet site it fails with no connection.
The 4G indicator is on, but no curved lines showing activity. I assume it is in idle, but will not come out.
The workaround I am currently using is disable and re-enable 4G data.
Does this sound normal? Has anyone else noticed this? While searching I found a few related posts but most were from a few years ago.
Usage so far has been in San Jose (No LTE yet), signal shows a few bars, over (-100 db).

Try going to Settings - Power, and make sure power efficiency, power saver, and sleep mode boxes are unchecked. This should fix the issue but you may see a slight decrease in battery life.

Power Efficiency was already off
Power Saver was set to turn on at 10%
I just disabled sleep mode. That might have been it. Only time will tell.
Any idea what the default idle time is for sleep mode to be engaged? and what exactly happens in sleep mode?

With sleep mode enabled, network connections are disabled when the screen is off. I've noticed the network connections also don't appear to reconnect once you turn your screen back on for some reason unfortunately.

im using nik's trinity rom sensation xl 4.5 .. my wifi keeps going off after a while when i press the power button n the screen goes off .. its like it disconnects the wifi in standby mode :S
It's entirely possible that it does. Try another rom if it's a problem.

Have you checked your power options?
if you are on power saver mode (if the rom supports that), then every time your phone locks all network will be disconnected to save battery.

I'm using the 14_M radio right now with this rom. Been using this radio since yesterday morning and I haven't had the wifi drop or disconnect as of yet that I'm aware of. Might want to give it a try.
Check the advanced options in Wi-Fi menu of settings, maybe the Wi-Fi sleep policy settings are set to OFF whenever SLEEP/SCREEN OFF. Change it to ALWAYS ON, or NEVER WHEN CHARGING. Tends to drain the battery a lot more, if set to always on. I use wifi manager by Kostya Vasiliyev (available in the Google play store) to get fast WiFi lock-on after screen on/wake.

[Q] Does wifi turn off during sleeping mode?

Hi to everyone. I forgat to turn my wifi off during my working hours. In the nd of my shift, i check my battery and it was proximately %5 left and even i didnt use the phone during my shift. it was %50 or something before starting. Does wifi still work even on the sleeping mode?
Thanks guys
no it stays on unless you set up the power saving mode i use custom settings so that wifi etc will turn off at 40% battery
wi-fi is a big battery drainer. Always have it off if you don't need it. Same with gps, data, and auto-sync for various accounts
Try using juice defender. I think the free version always you to enable wifi control (after your phone goes into sleep mode it should turn off the wifi until you wake it up)

juice defender is in itself a battery drainer. don't use those "battery saver" apps. they're all bs. just get in a habit of turning off connections manually when you don't need them.
Are you aware of the setting: wifi settings/advanced/wifi sleep policy and set it to sleep when screen turns off?

Thanks I didn't know about that setting, but my question is once wifi turns off mobile data kicks in. Which drains battery more? Wifi or mobile data?

They both drain battery equally as much. Mobile data shouldn't kick in unless you have it toggled on.

Use Green Power to automatically disable wifi and data when the phone goes into stand by. There are lots of settings like enabling wifi at certain intervals to sync email/whatsapp/other push services.
On GB for me it's the difference between losing 25% battery overnight without it and losing only 3% when it's enabled and that's with sync every hour.
It seems that on any ICS rom wifi doesn't use any juice even when enabled in standby. Because of the kernel bug in the leaks I'm now on the official CM9 rom and after almost 9 hours with wifi turned on I only lost 4%, on every other ICS rom I tried I get the same results.

I tried juice defender ultimate but connection was on and off and time to time it took ridiculous amount of time to get the connection back :/ also I don't know why with juice defender I noticed sluggish performance phone, after uninstalling everything was much more snappy.
I have wifi on all the time and I only lose about 2-3% over night on stock, I guess it's fine the way it is for me without using all those battery "saver" apps.

I disagree. I definitely get power savings with JD compared to without it. Auto-disabling WiFi saved loads of power for a start, and my overnight drain has gone from 3-5%, to approx 1% with JD running. I'm not saying all batt saver apps are worth using, but JD works for me.
Its a lot easier to have a well-behaved app that DOESN'T use a lot of power itself manage your connection toggling rather than having to remember to do it yourself.

Wrong. WiFi uses more power. Its a separate transmitter being driven by the battery, whereas as mobile data will use the existing transmitter (phone) that's already on, but obviously drive it a little harder than if it was all off.

[Q] Battery drain from wifi on CM9?

Recently, I switched from Oat's Light n' Tasty to CM9 nightlies (currently on 20121202) which I flashed with CWM. I have noticed that the battery drains significantly faster with CM9 when the device is asleep. Looking at better battery stats I found that ath6kl_wow seems to be the culprit, which was reinforced with GSam which reported that 89% of the battery was consumed by wifi. Any ideas of what may be the problem or how to resolve the battery drain?
Thanks.
Have you gone into the advanced WiFi settings and set it to sleep when the screen is off?
Additionally you could try increasing the WiFi scan interval in the build.prop

I want to be able to get notifications from the device, so ideally i wouldn't want the wifi off when the screen is off. I haven't edited the wifi scan interval yet, any recommendations on a time i should enter into build.prop?
You could try 180, but if you are always connected it won't make a difference.

[Tutorial] Battery saving techniques

So yes this Phone's battery unfortuanatly is not well at all.. but here is how i managed mine to last a day without charging. Let me also say im a heavy user also. I text A LOT and always pull out my phone in class play a few games to pass the time or just browse my phone. So this does work for heavy / light users.
Go to Wifi/ menu / advanced and click never on Keep wifi on during sleep.
Go to settings/ Location access - Switch to off
For your brightness it will be on Auto switch that off and put it almost to the lowest as you dont really need it high just kills the battery.
- Go to the App store and download Easy Battery savor. When you access the app choose intiligent mode. It really helps !
-Dont ever use live wallpaper it just drains it so fast.
- DOwnload Faux App It really helps (Faux kernel Enhancement Project) Once downloaded go to CPU and set max clock to 1.35 instead of 1.5. it will still be buttery smooth and it will drain the battery less.
Also I am using the Franco Kernel - nightly #53 which in my opinion really helps !
- Try to turn off the WiFi usage as much as possible and you will see a huge difference.
That's all from me guys. By doing all this my battery significantly improved and lasts about a day now.
Anyways if you have better solutionson how you manage your battery and how you extend its life.
- post pictures
- post the apps you use
- post everything !
Thank you !
I use harsh. Whenever I don't game, I lower the max freq to just 810mhz, ondemand, row, mpdecision on (as harsh recommended) and it's still buttery smooth, and of course battery life is incredible, and I also do check the Disable HW Overlays and Force GPU in 2d rendering. And since no kernel controlling apps are needed, my phone feels cleaner too I can't upload battery stats yet as I'm in an area with only edge connectiom and I hate using slow internet connections

A couple of things I noticed with this. The first thing I notice is, in two of your screenshots, you appear to have mobile data disabled completely. The second thing I noticed is that your final screenshot shows 24hr 52 min on battery, yet according to your clock, a it should really be a total of 33hr 6 min since unplugged. Your first screenshot shows 88% battery remaining with it already having been unplugged for 7hr 35 min. With that screenshot showing a time of 3:11pm, that would mean your phone was unplugged at 7:36am. If the phone was unplugged at 7:36am, then how is it only showing a total of 24hr 52min at 4:42pm the next day? It should be showing 33hr 6min. That's an odd inconsistency there. All in all, even with the data that is showed in your screenshot, it shows very little use as phone idle and cell standby are both in your top 5. Your screen was your highest drain, yet there isn't anything else there accompanying it. I could be wrong, but it seems to me that all you did was keep the data turned off on your phone, and connect to wifi where available. You turned your screen on, but didn't really do anything with the phone besides having the screen just on. That said, even stock with no changes, a person can get 24 hours on a charge if they're disabling their phone and not using it.
Interesting tips however I have a few points:
Your first tip suggests having WiFi to Never stay connected during sleep. I am part of another Android forum which deals with tablets. We tested this feature as with a tablet, you are likely to leave it for hours on end before using it again. It was excellent if the tablet was not touched, however we noticed that it significantly increased the battery drain if you were regularly switching between sleep and using it.
Agree with the second but don't throw away practicality, use Location settings when they need to be use, not just turn them off and don't use them.
Leave it on auto-brightness dude, why ruin the nice visuals of a fantastic screen by having it so dark you can't see it? I only ever use lowest brightness when its dark or the battery is nearly dead.
No idea about the battery saver.
I definitely disagree with this. If you use 3G permanently, like I do, then turning on WiFi definitely reduces battery drain. I don't turn off data ever, so switching WiFi where possible is quite a useful battery saving technique.

His solution is to turn off connectivity and functionality on the phone. That defeats the purpose of even having the phone at all.
That said, I think a safe UC of maybe 200MHz can have a difference, but to me, it's all about enjoying the phone and the phone experience. No need to screw with it
Don't do the wifi feature. It will use more battery because it will constantly have to reconnect to the wifi connection every time your phone comes out of sleep mode and that will consume more battery.

Just curious, why did you buy it then? Personally, I'm leaving everything on because I bought the phone for the looks and usability.
And yes, the phone lasts me all day while using it for everything including emails, conference calls, web browsing etc.
I've set up profiles using the Smart Profiles app to quickly turn things on and off at will - hit CAR and bluetooth/GPS turn on, Wifi turns off. Hit HOME and the reverse happens, etc.

Same thing here..but I use scripts When I'm in school and all I need my phone for is some tethering and music, I activate my script that sets the max freq to just 810mhz and I undervolt an extra -50mv from the stock undervoltages of harsh, but when I'm out and away, I enjoy the full 1.5ghz quadcore beast trapped inside my pocket

Don't get me wrong, it's useful to have a decent battery life, but I really don't see the need to turn the device into an expensive brick. My suggestions, which may or may not be better than the ones in the OP, but they seem to work for me on every Android I've come across without screwing with undervolting etc:
1. Turn Auto-Sync off, or increase the duration between each sync. On my old phone, the phone would use Auto-Sync every hour or so which totally killed the battery over the course of day. I turned it off and would sync it manually (taking all of 15 seconds) on a Friday. Made a huge difference, although simply increasing the time between syncs is just as effective if not more so as you still save a bit of time (might opt for that myself :good
2. Use Inverted Apps on SAMOLED, Don't use Inverted Apps on IPS, white colour uses more battery on SAMOLED, but a lot less on IPS :fingers-crossed:
3. Get yourself a Toggle-based Notification bar, you will remember to switch off your WiFi when walking around in public. To that end, switch your WiFi off unless you are connected to a hotspot, the constant scanning will drain your battery and depending on the interval may take quite a large hit over the course of a day. If you rely on WiFi then maybe increase the scan interval time.
4. Turn off all mobile networking services when in a known signal blackspot. e.g. When work pays for us to go to a hotel on the Welsh border in Cheshire, there is absolutely no signal guaranteed unless you go to the end of the driveway, so I turn off all phone services unless I am there. Your phone will drink your battery very quickly otherwise, guaranteed. The easy solution is to use WhatsApp, switch your phone onto Airplane mode then turn on WiFi and connect to a hotspot (if they have one available, hotels usually do). This is surprisingly low on battery consumption.
So basically, just leave my phone in my pocket and not use it. Okay. Gotcha.

My battery life is amazing. I guess it just depends on what you compare it to. I had an evo 3d before, and my 3d would be dead by noon without even turning on the screen. My work blackberry lasts 5 days with fairly heavy email usage.
My N4 though, I use it fairly often for browsing, occasional calls throughout the day, streaming audio, this and that. After 12 hours of use I am still at 60% usually. From 7am to 5:30 (typically when i get out of work) I will be at 70%+
Not sure why people are so bent out of shape about it...
On my 3d if I ran facebook app or any stupid **** like that it would kill my battery like i didnt even have one.
Here's another idea get a job or pay attention in school. That will save battery life as well. I have literally seen people stare at a screen without doing anything with the phone, just because they are so obsessed with it being in their hand
Oh and my Sig does not represent the nexus in the mail

Difference Between Sleep Mode and Data Connection in Power Saver

I was just wondering that is the difference between the two. The description seems to be the same in both but they are located in 2 difference places. Sleep Mode under Power in settings and Data Connection under Power Saver. If both are turned on is there any conflict or whatnot?
Sent from my HTC One using Tapatalk 2
The power saver options turns off your data connection as soon as the screen is off then reconnects it when the screen is on. The one under power waits until your phone has been inactive for a while (6+ hours in my experience) and turns then turns the connection off. They won't conflict because enabling the one under power saver will naturally make the other one redundant.

Oh great! Thanks for the explanation. Okay so let's say power saver turns off your data when your screen is off, what happens to messaging services like what's app, viber and Facebook chat? I won't be notified of any of these when the screen is turned off on power saver mode?
