Battery loss theory - Transformer TF300T General

I have had random battery loss dinner the 4'2 upgrade. I think I know why. If I stay on one WiFi router I'm okay. But when I go to work my tablet does not go into deep sleep. I think it is searching for a WiFi signal. I have 3 wireless routers at work and since I am the sys admin my tablet is associated with all of them. When I open the tablet and lock onto a WiFi signal then it will go to sleep.

Help with wifi issue

I constantly use my tab with wifi at home and I have noticed that when my tab comes off standby (after unlocking screen) it connects to wifi, it never used to to happen. Running stock ICS, anyone started experiencing this? I think this is also why my tab runs hot and battery drains.

I think I may have solved my issue, under advance wifi settings I selected to "Always" have wifi on during sleep. My battery is not draining as much as before.

[Q] Weak wifi signal

Not sure what has been up lately, but my M has been struggling to maintain a wifi signal here at home. My old Droid Pro has full signal as does my Kindle Fire, but for the last week or 2 my M has been struggling to get the wifi signal and when it does, it's not full bars. About 1-2 bars when all my other devices have full wifi bars. Even when I am 3 feet from the modem (fios) . I've restarted the phone a couple times, but same issue. Where am I going wrong here?

Check your settings. Maybe if you choose the specific frequency for FiOS and toggle the weak connection command; that may help. Do you have any smart actions or battery saver that may be trying to optimize your WiFi radio for battery management?

Great suggestions! I did more research today and did specify which channel to broadcast on for the modem.. It may have helped a bit. As for smart actions, I do indeed have those running but only for battery level below 15 percent or specific overnight hours. I will look more into the router settings and report back my findings. Thanks for the help!

Battery tips

Alright. I'm getting horrible battery life. Do you guys have any tips? Even after a data wipe its still bad. And tips specifics to this phone or general ones? Thanks

Are you in an area with poor reception?
You can try turning GPS and WiFi off when not in use.
You can also root your phone and feeeze/remove bloatware.

I had the same issues after my update. I then went and froze mobeam, all Knox services, enterprise.knox, knoxs.eventmanager, and a Security wipe apk. Let my note drain all the way until it powered down. Let it charge full cycle while turned off. So far work 1hr and 45 mins of on screen on time I'm down 15%. I feel like that's decent. Been on xda app pretty heavy and 2 different games straight with no screen timeouts

Best tip I can give in general, whether you're experiencing bad battery life or not, is to learn how to bring down the Google based wakelocks across play store, youtube, account sync, maps, hangouts/talk etc
So how does one do this? First, do the obvious by going into each Google app - Menu key - settings - and untick things such as annoymous usage data, google mob ads etc. Delete apps you don't use if you're rooted too.
Disable Account Sync altogether if you can, location services in gps settings, bluetooth, nfc
More advanced things you can do is learn about "wakelocks" here: http://forum.xda-developers.com/showthread.php?t=1827676

Is your wifi enabled at all? If it's enabled and not connected then chances are it could be scanning for networks which would cause significant power drain.

I went into the wifi /menu/advanced and turnedoff the wifi scanning for Google Apps and location even when wifi off. That is insane! Made an hour a day difference in usage.
On a side note, the signal on this firmware is better than. The wife's retail version has no signal in a store and I had 4g with two bars

I feel like my battery life is slightly worse as well. Although that could be attributed to what seems like weaker data signal. So idle time seems to hold up just as well. But the battery seems to drain faster when using data. I was going to monitor it for several more days and if it's still bad, i'm going to try flashing the MJE modem

For those running 4.4.2 on the Verison Note 3...did you all have to subscribe to the Chinese bot-net via Kingo Root, or is there another method to install a ROM? Is Safestrap the only option, or is there a full recovery available?

My battery life has gone to hell since the 2nd 4.4.2 update on [email protected] last week. I was getty 36 to 48 hours every time. As soon as the new update went in things changed the next day. Now I am lucky to get10 to 12 hours out of it. I have started pulling app but nothing has worked.
The battery drain on my once perfect S4 is now worse then on my LG Thrill!
Some things that helped control my battery in Kit Kat
In KitKat Google changed how location services works which seems to cause a lot of the battery drain issues. If you have Wi-Fi turned off during sleep, apps are likely trying to get your location using GPS which will easily drain your battery. It seems like even with Location Services is turned off that some apps can still continue to try and request location. Personally I like using the location services and that many apps use in Android so completely disabling wasn't an option for me.
I've played around with it quite a bit myself and found these settings have helped me::
-Leaving Google Location Services on at High Accuracy has been better on my phone's battery life.
-Leave Wi-Fi always on if it's available. (Use something like Llama or Tasker to automatically turn Wi-Fi on and off.)
-Setup My Places in Locations that correspond to Wi-Fi, etc
-Try uninstalling/reinstalling updates to Google Search, Google Play Services and Google Play Store
-Go through your apps and uninstall anything you aren't using or is not from a reputable developer. A lot of apps seem to have keep awake and location permission enabled by default that don't need it. You won't see these apps in the battery screen because they hide behind tiny wake lock requests and Google Play Services.
Another tip for saving battery is to use LLama or Tasker to disable Account Syncs any time you disconnect from a Wi-Fi network.
Good Luck and Cheers
