Battery life/4G - Motorola Droid RAZR

I've considered switching to VZW from T-Mo. One of my concerns is battery life with 4G. Can 4G be turned off with something like Juice Defender? Do you really need 4G while your phone is sleeping, pushing e-mails?

You can change it to 3g only in the network settings.
The only time I need 4g is when im showing off.

Yes, there is usually a switch between forcing LTE mode, deactivating LTE, or allowing your phone to choose between 4G and 3G based on signal strength.
Another thing to remember is when you're at home, you can use your wifi connection.
I have had both the HTC Thunderbolt and Samsung Droid Charge, so from my experience keeping 4G on is craaaaazy fast battery drain.

Yes, but can I do it systematically? Also, can the phone pick up 4G while you are on a call to instantiate voice & data simultaneously? I would use the data speeds regularly, but don't need them while the screen is off.

BUMP......

It probably can be done with smart actions? I haven't taken a good look at it yet, but seems promising.

Bump bump bump

Bump........

there are 4g toggle apps in the market making swapping service very easy.. 2 nights ago i went about 10 hours w/ 4G on with moderate use before getting a 20% battery warning.. last night i tried 4g off, went to work, forgot to plug my phone in at night and woke up to 50% battery, unplugged for 20 hours (both nights i had a full charge before leaving for work).. it's a pretty drastic difference, 4G is blazing fast tho, i'd love to be able to keep it on 24/7..

Battery life with low reception

I am amazed by the battery management of the phone. Where i work is practically a bunker, almost no signal at all. The phone keeps jumping from sprint to roaming all day. And i still manage to get out of work with 30% battery left. My epic was always on the charger.

Mine's been good at my office too (virtually no Sprint signal), I'm really happy with the battery life so far. I have missed some calls due to jumping between Sprint and Verizon, but I expected that to happen.
anything you guys did with settings or something, because that is NOT the case with me. In the back office where I work I get low signal and goes to roaming, phone barely lasts the time that im there.
Havent been at work the past two days and the battery life is great, went over 24 hrs without a charge with light usage. Dont really use it that much at work other than a few calls and txts and some very light web browsing in the areas I get data connection, not enough to kill the batter like it does I would think.

I have facebook, htc, etc to manual sync. Other than that is stock

If you don't use Facebook or any of the other carrier bloatware, uninstall it via the settings > applications menu. I was surprised how much I could remove without having root, it's really nice to see.
I managed 50 hours off of a single battery change over the past two days, battery saver mode (set to 15% threshold) finally kicked in this morning, but I have great signal strength at home and work.
IMO the battery life is much better at stock on the 3D compared to the 4G, but it still isnt great. Im sure once we get custom kernels and ROMs that things will get better.

Do you have 3G on or just 2G?
It shows the 3g icon

Musings on battery and 4g

There have been some posts on battery life being terrible lately, and here is a little alternative way to improve your battery life that I found out by accident.
We all know that Sprint 3g speeds have been taking a crapper lately, I don't think I even get 300kbps downstream anymore. I wanted to download a ROM so I quickly toggled on 4g (which I hadn't used yet on my phone) and found I was getting downstream of 2mbps - 4mbps, not great but certainly 10x as good as my 3g.
After my download, I mistakenly left 4g enabled. I come from the OG Evo where if I left 4g on my phone was dead so fast at work due to no signal. However, I found that my MoPho just put the 4g radio on standby and didn't need me to do anything and the battery wasn't draining.
So I came to this conclusion, since the 4g radio management so far seems to be pretty good for the MoPho, if the power consumption by the 4g radio is < than the factor of speed the speeds are over 3g, maybe some Angry birds, I can't remember, then it is probably worth it to leave your 4g on. Save battery + faster downloads = win!
I don't have a screencap for this, but the other day, I was off my charger for about 16 hours, had 15-20% battery left. I streamed some Pandora, downloaded a bit, read some RSS, email, a couple texts, some phone calls and had the 4g enabled all day. Not bad I say.
Doesn't 4G still have to come on every so often to push or pull email and whatnot?
Yea, but the premise is still sound I think.

does using 3g noticeably kill the battery?

check out the pic. notice when i went to 3g when i went out for a bit, my battery just dropped... i didn't use the phone that much when I was out, and it still drained that much. hmm.
actually right now I can't upload a pic. anyone else having that issue from the app?

No problems on my end bro!
VZW has had problems with their data system for the last 3 or 4 months. Your issues are probably related to to the problems all 4G phones are experiencing these days. You will see people in all the 4G forums complaining of losing data and low signals killing batteries. Saturday I was in a low signal area and kept losing 4G down to 1X and that also heated up my battery for the first time since I got the phone.

LTE 4G Rezound
i just have nothing to compare it to, because everywhere i go, i use wifi all the time lol....i haven't used just 3g in SO damn long, so i don't have a basis to compare with the rezound
Idling on 3G doesn't seem to hurt me too bad (I usually let juice defender keep it off to mitigate the risk), but actually using it is way more draining than wifi. I can sit online all night at home on wifi, but only get about two hours of solid use when I'm out and about.
Going to a 4G city this weekend for the first time. Bringing backup batteries.
I think what may be happening is that once it drops to 3g or 1x it tries hard to get back to 4g and that is what hurts more than anything.
Try forcing it to 3g only and see if you have the same drop in battery under preferably the same conditions.

Yes,that is what happened to me Saturday,it dropped to 1X and overheated trying to get back to 4G.
I did force it to 3G and it still stayed hot. But I had that happen once with my Thunderbolt, so I feel it is the vzw data signal not the phone.
3G kills battery compared to wifi.
i shut off 4g the day i got it lol...yeah, i think 3g just uses noticably more battery tahn wifi

definately. i can sit at home, connected to my wifi, and i can get like 2 or 3 days out of the battery. with light usage that is. on 3g though, with light usage, i'm lucky if i can get a full day.
3g actually saves my battery, somehow 4g and WiFi take more battery for me

Random loss of 4G service [SOLVED]

Not sure if this has been posted before, so I apologize if this is a repeated post.
I had been losing 4G service randomly over the past few days. 1X and 3G would be the the only service I would receive in places where I previously been receiving strong 4G.
The service would also return intermittently.
I have an extended battery and a standard battery, which I have been cycling through full charge / discharge.
I have Fast Boot turned off in power settings.
What I have found is that my cell network settings reset or change on their own, each time I shut down and/or do a battery pull.
Normally I have Network Mode set to LTE/CDMA and Enable Always-on mobile data is checked.
What I think is happening is that when I bring the battery down to nearly 5%, my power-saver settings shift from Performance to Normal. My LTE is then shut off and when I replace the battery with a charged one, the power saver settings remain in Normal, with LTE shut off.
I'll spend some time verifying and I guess the answer is really to not condition my batteries by discharging past 10%.
I may also be allowing this to happen by responding improperly to the low battery notification.
Hope this helps anyone experiencing loss of 4G...

Verizon has had some disruptions this week, nothing wrong with your phone.

Battery saver mode shuts off auto sync, 4G, and always on mobile data. You need to set battery in settings back to performance instead of normal or economy.

I actually checked that in the 4G outage thread, but two respondents from my area (NY/NJ) said there were no outages. But I think that's why it was so hard for me to troubleshoot the other reasons for my 4G loss.

There seem to be some quirks on the phone. I will see 1x to 3G to LTE (in that progression) if I have been in an underground parking garage, or maybe a weak WiFi that comes in and out. For the most part, when I see 1x or 3G, I assume verizon is having some issues. 99% of the time it just comes back. 1% or less (probably less), I toggle mobile networks.

4G Toggle for VZW SGS3?

searched Google, Google Play and XDA. cant find a toggle widget or even a manual method to switch to 3g that works. anyone got any ideas?
the LTE is stupid fast in my area, highest i got so far is 47.7Mbps down and 14.5Mbps up buuuut.... its murdering my battery even at idle.
when i jump on WiFi battery life seems awesome. thinking 3g will be some ware in the middle?
thanks

I'm curious as well!
I would love to be able to toggle my LTE on and off.
I really hope someone figures this out soon.
Don't see anything out there yet...the Thunderbolt app doesn't work, either. I guess patience is our only option at this point.
Would be very interested in this as well. I used 3g on my thunderbolt 99% of the time to let it last all day, this is a necessary option to have.
yea. dont get me wrong. im really loving how fast the 4G network is. its literally the fastest network ive ever been on hands down.
but... i dont really need that much speed 90% of the time. for general stuff like email and random background data services its just not worth the hit on battery life. even at idle, when im away from Wifi i watch my battery % go down the tubes...

that worked. thanks!
Thanks for link. Tried that method out, seems like all i get is 1X and never see 3G... Not sure if coverage would play a role in that cuz I have 2 bars at the moment where I work.
try toggling airplane mode to get in to 3G.
so far so good. 4G must have been why my battery was draining so fast. been 30min off the charger @ idle on 3G and still i have 100% battery left. on 4G it would already be down to about 96%.
if someone makes a toggle app that works for the VZW SGS3 i would gladly pay a few bucks for it. :good:

Tried that and it worked after couple minutes but it keeps going in and out of 3G and sometimes goes into only 1X
must have something to do with the service in your area maybe?
mine seems to work pretty easily. going back into 4G is almost instant. but when i switch into 3G it does take about 30sec or so. sometimes i see it flash the 1X icon but its very quick and only seems to be doing it when i switch it, after that it just stays in 3G.
1hr 20min off the charger and down to 99% this is a HUGE difference from what ive been seeing on 4G. :victory:
maybe. The area is kinda crappy here where I work. Even on my Nexus i was getting 3G but it would go out. We'll see what happens when I leave
