LTE causing battery life problems


pyroscott

Recommended Posts

When 3G was first introduced, it seemed like battery life plummeted because 3G service was spotty and the phones were always trying to connect to 3G while they were already connected to 2G and voice. Now it seems that many LTE users are having troubles with LTE draining their batteries prematurely. 4G coverage has not developed fully and service is spotty. Unless the user wants to continually switch their 4G radio on and off, they face the decision of fast connection or battery life. Fast Phones, Dead Batteries points out that Android and windows phone manufacturers have the opportunity of offering LTE enabled handsets before Apple comes out with a LTE handset, but some buyers are shying away due to other buyer's complaints about spotty service and atrocious battery life. It will get better as more and more towers are converted to LTE, just like when 3G was rolled out. We will all have to suffer through it for now, or fall back on 3G speeds and shut off our LTE radio for now.

That is an interesting article. It's not something I had really considered when I think about how poor battery performance is with 4G devices.

 

I just moved to a new house last month. I'm much closer to a Sprint tower now. I now always have full bars with a -65dBm to -72dBm signal. I used to have a -91dBm to -96dBm signal. My battery life has improved about 30% to 40% with the move to a better signal. In standby, my E4GT will only use about a third of it's battery life in a full day. My work BlackBerry is even more dramatic than that. I last charged it up on Friday during the work day. Right now it still is at 75%.

 

When it comes to battery life, there is no substitute for a good strong signal. And 4G would be no exception to that.

 

Thanks for posting the article!

You should wait and see the results of Qualcomm's new S4 based chips when they start being put in devices later this year. They have been able to embed the LTE modem directly on the die of the chip which according to them will help greatly with both battery life and also performance.

Currently no one else is offering this nor from what i've read has even planned to do this.

 

MWC coming up at the end of this month and then CTIA a little later after should have some devices with these chips in them and be able to give some better specs on battery life and such.

 

Signal is everything though too, esp with phones these days. lower signal typically results in lower speeds, which will also in turn make your device work longer to get the same amount of data/information.

I must be a major dork. Reading this got me really excited! Thanks for the post. :coolbeans:

Yeah they didn't give any real #'s for improvements expected but heres a link to one of the vid's they talk some about it along with some other stuff they are working on, on the side like facial recognition...

The next leap will have to be battery performance, you can only squeeze so much efficiency out of a chip set unless we start talking Star Trek stuff which is a couple of centuries ahead. I read an article last year where GM and other companies are starting to squeeze battery makers to make improvements and R&D dollars are starting to flow, at least on the car battery side for hybrids. Now if the OEM's and carriers would start making some noise on their side.

Mirasol displays and nano battery technology will extend battery life in the average smartphone and tablet to days and weeks. Mirasol displays will be on the market in a big way very soon. Nano batteries are another 24 to 36 months.

I'm not overly optimistic that we will ever see more than a day or two as the phones are just going to get more powerful. If the mid-range devices adopt some of this tech, they might get some really good life.

If I could get 24 to 48 hours of heavy usage on a 4G smartphone, I'd be stoked. I wouldn't need more than that.

Well when manufacturers start thinking a little more like how Moto did with the Razor Max you'll get closer to it. Can't tell you how much it boggles my mind that they continue to try to make phones so freaking thin but in the process still leave a "bump out" on the back for where the camera is and such. Make the back flush and battery bigger and that solves a good chunk of battery life...

The thinness craze does seem to be getting out of hand for some models, no matter how convenient it is for your pocket. Those phones could handle a bigger battery, but if we'll probably see a smaller camera one day that will make the phones even thinner.

I agree, not to mention there are always some battery-makers out there that manage to squeeze a higher capacity battery into the same size battery as the stock one. I would prefer that the camera is recessed instead of like the Evo 3D where the phone rests on the camera when it is not cased.

I agree on all this. Anything skinnier than the GSII series is gimmicky. Its not practical. And super thin phones are awkward to hold and type on.

 

Give me more battery capacity over ultra thinness. And the RAZR MAXX now proves what can be done with today's technology.

 

And since we all are looking at a battery life hit with LTE coming up, I want more battery!!!

    • Just installed the update, and it's good!  As you recommended, I turned off both TA adjustments, and turned on displaying it when it's zero.  The value is basically spot-on.  It's bouncing between 18 and 19 for the Cameron Valley site, and it is in fact between 0.87 and 0.92 miles, as displayed in the app.  This is probably a better estimate of the TA values than any other device I own provides. As far as the -44 goes, I'll have to take it out and verify that it no longer records those cases. If this device didn't have that annoying reset problem, and got the Android 14 update (and in so doing supported TA on NR and continued to allow band locking), it would easily be the best device I own.  Easily.  And would be the device I standardize on for the 5G era.  I'll probably have to wait for a future device to come out with Android 14 and then see what happens. And I know I didn't have to, but I love SCP.  It is my primary tool for tracking the goings-on of the various networks and is very easy to use and work with across my 10 phones.  I am very happy to send a token of my appreciation your way now and then.  Thanks again! - Trip
    • Sorry, I misread your message -- yes, the app would show 0 if an invalid value was being reported. I don't think I had any MediaTek devices myself, but the beta testers have had a decent variety of devices over the years.   Sorry, I didn't word that very well in my last post -- I added an option to control display of LTE TA when it is 0. By default it will now be hidden (sadly a lot of devices do not show it) but anyone who wants to display it can adjust accordingly. There will be 3 user-selectable options related to LTE TA now -- the existing correction option, correction on LTE-TDD (which is independent/in addition to the existing correction option), and TA:0 display. In your case, I'd disable the TDD option and enable the TA:0 option; the defaults will be the opposite of what I think you need.   You did not have to do that, but I sincerely appreciate it, thank you! Beta update is rolling out now, let me know how it goes.
    • In order: This is very helpful to know.  Thanks. That makes a lot of sense, though it's showing me zero rather than nothing; it looks like if it's calculating a negative number, I'm seeing zero instead.  It makes me wonder how many devices you've tested against which use the MediaTek chipset.  This is only the second one I've used, and the first one was very, very old (didn't have B41), so it's possible that the MediaTek chip doesn't need the correction while others do.  Separately, I doubt that a real world case will ever see 1282, so I imagine any value above 1281 could be ignored. I would ask you to please not hide TA values of 0, or if you hide them by default, add an option to not hide them.  I am aware that, for example, the S22 doesn't report a valid TA value and always reports zero, but zero is a legitimate value and is useful to know when trying to identify sites. I'll look forward to your impending update, and I'm going to send along another donation if I can find the link.  Thanks so much, as always!  - Trip
    • I received the reports, thanks! You didn't catch it happening (it captures the diagnostics as soon as you hit send or long-click the connection banner on the main screen), and I had sent you an e-mail to clarify which value was -3.. but your screenshots confirmed my hunch that you meant RSRQ!   I know exactly what is happening here. Somewhere along the way, I learned that TD-LTE bands (33-53) needed a TA correction of -19 applied, and I confirmed it on several devices. Perhaps that is no longer universally true.. but what you're seeing SCP display matches that correction. Below 19 you see nothing, at 19 you see 0, and above that you see TA-19. The upper limit is 1282, which is why you see 1263. Your phone must report 1282 when the TA is unknown, which is not technically safe but I can work around that. Funny enough, I had a change to TA coming in the next update that had nothing to do with your issues.. TA:0 will be hidden moving forward, since several devices report 0 when it cannot be identified. I'll have an app update out shortly that addresses all of this, let me know how it works for you and thanks for the detailed feedback!
    • Mike, We ended up going out this morning to do errands in spite of the tropical storm.  I locked the phone on LTE B41, turned off the TA correction checkbox, and watched it carefully while out and about.  I have four screenshots for you. https://imgur.com/a/kCPTCnB First, I happened to get a screenshot of it doing the -44 dBm thing.  I also tried to send you at least one set of diagnostics showing the -44 dBm but I don't know where precisely in the process it collects the diagnostics.  Hopefully there's something useful in them. The rest of the screenshots are far more interesting.  All three were taken within seconds of each other in the CVS parking lot.  The phone's diagnostic screen shows a TA of 17, and oddly, the SCP diagnostics screenshot also appears to show a TA of 17.  But SCP's normal display is showing 0.  Not entirely sure what to make of that.  It looks like SCP won't show me a value other than 0 until I hit about 19 according to the phone diagnostic screen. It also appears that when SCP is showing a TA of 1263, that's the equivalent of a null value for the TA--no TA is calculated.  The phone diagnostic screen appears to show just "12" when that's happening; the SCP diagnostic screen shows 1282 in the TA section when that happens, a difference of 19, which is highly convenient given what I noted above about the TA value.  (I can't test that the phone diagnostic screen is limited to two characters and is thus truncating 1282 to just "12" as I suspect given where I am right now.  Had I known to be looking for it, I'd have tested in the middle of nowhere yesterday.) Anything catch your eye?  Anything I can do to help more?  - Trip
