Crappy Battery life, try this!

So I had just gotten done posting a smartass remark about how I had gotten two days on one charge with my phone, only to pull it off the charger go to work, and have the sucker die in 4 hours.
I figured out what I did, and you should try it too, it may help you out. I am running the leaked radio btw.
So earlier today I decided to go into ##778# and type the password 000000 and then modem settings and rev A and change it from Enable to eHRPD because I figured with the 4G network back I could use the dual radio 3G network. Well That is when my battery life went to ****. I pulled my phone out of my pocket to it burning hot and at 9%. I quickly changed it back to Enabled, and it survived the 9% all the way to 5% over a period of another 6 hours.
So unless you need to talk and use data at the same time, use the regular 3G network like I am, and see if your battery life doesn't improve. I still am on 4G all day, but this was literally the only feature I changed on my phone between amazing battery life and crappy battery life.

You can still do talk/data at the same time on Rev A with 3G.

Right and at the moment, no thunderbolt should have eHRPD. No matter what verizon says. So we're all running on rev a right now, and you must have done something else. EHRPD will not waste your battery any more than normal.

Actually mine is set to eHRPD. Just bought it from Vzw a few days ago, rooted and flashed DBamf 161 along with the new radio and Im still set to it.
Making me think I should switch it hmmm.... hmmmmm

I just checked mine and it was set to eHRPD by default. Does this mean I should change it to enabled or leave it alone?

It doesn't really matter what it's set to. It seems as though Verizon has made all Thunderbolts default to Rev A in 3G areas after the outage rather than eHRPD regardless of what the modem setting is. You can check under About Phone-Network-Mobile Network Type

I use the LTE on/off app and Juice Defender Beta to increase battery life.

Set my phone to eHRPD then rebooted it and it went back to enabled I think Verizon is doing a tower by tower fix.

Mine is rooted and I get almost 2 days of moderate use out of it. Its the only way to make this phone truly great.

what kernel/governer do you use?

I'm running das bamf 1.6 remix with the stock radio and the kernel it came with. I know that it isn't really necessary to wipe but I did. I used a battery calibration app and auto brightness.

worked great for me thanks

I'm also using the smartass setting as well.

What are you guys using?
sent from my B.A.M.F Thunderbolt

I'm currently using Tesla Coil 1.7.1 with imoseyon's batt saver kernel, setCPU using the smartass governor.
Today my battery life was absolutely horrible: 6 hours from 100% to 19% with 1 hour of screen on time at ~25% brightness, 8 mins of call time and maybe 2 hours of music off of my SD card.
I just can't figure this phone out...

I have noticed that as well. Some days my battery rocks, and some days it sinks like a rock. Not sure why. It's as unpredictable as my wife! LOL
sent from my B.A.M.F Thunderbolt

The other thing I do is if I know I am not going to use my 3G or 4G connection I turn it off until I need it. This Rom I use has a widget for switching it on or off.
sent from my B.A.M.F Thunderbolt

The battery sipper kernel is the only kernel for me. Using the same Rom I went from about 6 hours of constant 4g to over a day of 4g. I do have the extended battery. I leave 4g on ALL day and get more battery life than I did on any other phone. I love that Damn kernel.

So does changing the modem do anything or not? I just checked and my Rev A setting is eHRPD and under about phone, it says CDMA-eHRPD. I have not changed anything other than turn LTE off when not needed, and when I turn it off I select CDMA auto (PRL). I am using the new radio and BAMF 1.6. I get decent battery life so I am not too concerned, but I am curious.

Poor battery life ?

As the title says i have poor battery life i have everything turned off ,background data,auto sync gps and all that whit screen 100% on i get 3-4 hours of music whit a total time on of 55 mins and battery is dead ?
I calibrated this Thing didn't work but i noticed at school it drains faster... Can the fact im having only 1-2 bar of signal in school drain my battery ??

It can do. To what extent it drains your battery, I'm not sure but it likely does impact it.

according to other battery drain threads, Low signal is a MASSIVE battery drainer, Your phone will be constantly searching for a stronger signal, hence using more power to do so.
Try to use 2g networks only (GSM) in school and that may help out a little, At least if you can get a stable 2g signal, the phone wont be working overtime to get a better signal. Such as 3g..
You can always switch back to 3g after school.
Besides your in school, You should be learning, Not pissing about on facebook and XDA or whatever you kids get upto !

In areoplane mode the radio will turn off so you wont receive calls or text, But you phone wont be searching for a signal so it will improve battery

CM10: Does switching off LTE save a lot of battery?

Before I start my own exhaustive test, I thought I would ask to see if someone has already done it...
I notice in CM10, you can go to MOBILE NETWORKS in the settings and pick either:
- LTE/CDMA/EvDo
or
- CDMA/EvDo
Does switching to the latter (no LTE) produce a noticeable battery savings? Is it worth doing if you don't use data intensive apps?
Thanks!

Turning off 4G usually saves battery life.
In CM10 it definitely saved my battery life.
I still got horrible battery life on CM10 no matter what I did. I went back to touchwiz and am getting 30+ hours every charge with about 5-6 hours screen time.
Sent from my SCH-I535 using xda app-developers app

If you are in a area that 4g switches back and forth with 3g thwn ya it will save a lot battery. If you are in a good 4g area and just run in 3g ya it will too save some battery because the LTE radio isnt active (4g and 3g use different radios)

[Q] Tips for Skyrocket in Non-LTE Area

So does anybody use their Skyrocket full-time in a non-LTE area?? I'm back home now for the holidays and don't have LTE here, and my battery literally went from 97% to 37% in 2.5 hrs with 49 mins of screen on and 59 mins of awake time. Meaning no significant wakelocks. Just the radio trying to find LTE. Is the battery always that terrible for you guys in non-LTE? I get a consistent ~18 hrs with 3 hrs screen on time while on LTE 24/7.
What do you guys do?? I tried flashing the Rogers radio and switching the Network Mode, but it does the same thing as on an AT&T radio - switches right back to LTE. I tried selecting the Network Operator but I never get any choices to even select AT&T like others report. *#2263# doesn't work on CM. I tried switching the mode in *#*#4636#*#* but it switched right back to LTE. What gives? (I'm on CM10.)

For a while I was in a non lte area. I had better battery life then than I do now in an lte area. I don't do anything different. I use uclf6 radio, which gets the best signal for me.

Man that's interesting. Every time I come home to PA from Atlanta, my battery just tanks. I can't even make it through half a day. And the only difference is going from constant LTE to no LTE at all. No change in my daily routine. And I've been using UCLF6 since it came out. Now I'm on the Rogers RUXLF3 because I wanted to try switching network modes, which didn't work. I don't know why it works for everyone else.

Sometimes when you move far distances they might have to reset something with the network. When I moved from pa to Florida they did some kind of network reset or something to my old iPhone. Not sure if they still do that or not. Now I travel from Texas to Louisiana and Mississippi a lot and I don't experience any battery tank. And I don't have lte in Louisiana or Mississippi. I get better battery life there then in Houston on lte.
Are you carrier unlocked? Even if you are I don't think cm10 based roms are able to switch network mode. That's if I remember correctly, which I could be wrong since I don't use that feature.
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2

Ohhhh I didn't realize that about CM and the network mode - thanks! I think I'm gonna try out the leak or Jedi and see how things go with that. I'm not carrier unlocked - just straight up AT&T.
That's interesting about the reset for location. I never heard of that. But I bought the phone here in PA, with a PA number. I've just been down in Atlanta for grad school. We're really close with our AT&T sales rep though so I could probably ask her.

Yeah ask the rep, he probably knows more about how the network works. What's weird is, I've not had a battery drain when going to non lte areas and spending weeks there. It actually saves my battery. Here in Houston I hit 40mbps/s and it probably burns through battery 15% faster than non lte areas. I have strong signal in both areas. Usually -75 to -85dBm. So it's not a signal fluctuation issue. Do you have weak hspa signal in pa?

Looks like I'm going from about -90 to -105 dBm. So I guess that's not too great. Unfortunately, I can't tell you what I get in Atlanta.

Yea that could definitely be it. Didn't think about that. But man that just seems like a huge hit in battery life - from 18 hrs down to 4 hrs. And I never had that problem with my Captivate, or my dad's Infuse. That's why the only major variable I could think of was the LTE.

It's always looking for lte, and now it has a crappy hspa signal. I'm guessing that's it, but it could be something else.

I'm on aokp and what I have to do is search for networks manually and select AT&T. Once you do that, you can force the 2g only option. Or *#*#4636#*#* and select the network mode you want. I'm on Rogers radio on AT&T and my phone isn't unlocked.
It can take like 2 minutes to search when you first do it manually.

As I stated in the OP I tried both of those things and neither worked. I'm on Rogers radio on AT&T and not unlocked. I tried searching for Network Operator but all it does is flash a popup saying Searching and immediately disappears. I've clicked it a million times. Sometimes it takes slightly longer, but still never gives any results.
And then *#*#4636#*#* just switches the mode back immediately after I change it.

That's strange, I've only used my phone on at&t. Never unlocked it. It works fine for me.

Build prop tweaks ?

I just want to know if their is any kind of build prop tweaks to increase mobile data connection.. I live in Chicago get great T-Mobile LTE service (see screen shots) but don't seem to have strong connection.. Or does having connection full green not matter ? I remember on my GS3 there was fee build prop tweaks to fix that .. Also I'm on cataclysm rom with faux 014u kernel

Try flashing the .17 or .15 radio. It seems to help LTE performance.

so whats wrong with your data speed, its better than many other people get?

Nothing is wrong with it I was just wondering if the signal could get better/ stronger .. Like a green bar.. Not that weak yellow I was just wondering

the signal varies depending on your personal location. it can vary a few steps from one spot to another, time of day, and depending on how busy your local network is. theres nothing that with help you with your signal. from the looks of it, your data signal is good.

Thanks guys I was just curious To see if better signal will get me better battery life.. battery life is good but you know gotta always want more
